TV cable from the socket to the TV. Types of television sockets and methods of their installation. Instructions for connecting the socket

In modern apartments or houses, two or more televisions are often installed. Previously, when only one TV was installed, a TV cable connected to a collective antenna did not cause much trouble. It could always be hidden, for example, under the baseboard, although this was not always possible.

Laying of television cables

Now, with several televisions, the problem of television cables becomes very acute. Using the old installation methods, all rooms will simply be wrapped in wires. You also need to remember about the Internet wires. Therefore, with so many wires, special measures are needed to reliably hide them without disturbing the interior of the premises. Connecting a Legrand television outlet will help to radically solve this issue.

Ideally, all cables should be tucked away with electrical wires prior to plastering. Moreover, the quality of such cables should be very high and, accordingly, high-quality installation with the provision of additional protection... To avoid possible interference, keep power and antenna cables at least two centimeters apart. Although modern TVs are capable of cutting out all the interference, it is better to have additional insurance.

The cable itself must have a high-quality braid that is resistant to most interference. Since, in addition to the antenna, the TV is also connected to the network, it is necessary to use an outlet for the power and antenna cables. If you need to connect any additional equipment, there may be more power outlets.

Using a splitter

In order to distribute a television signal to several televisions, a special device called a splitter is used. This device has one input and several outputs. The initial signal of the antenna cable is strong enough for one TV set.

When connecting multiple TVs, the signal strength may drop significantly. In order not to pay the provider for the connection additional TVs, you can connect a TV amplifier. In the connection diagram, it is located as close as possible to the signal source. Usually, this is the entrance to the apartment or a TV panel installed in the entrance.

Thus, connecting a Legrand TV outlet solves a large number of problems. The interior of the premises is preserved, and the signal quality remains at the proper level.

How to connect a TV outlet Legrand

Before proceeding with the repair work in the apartment, it is necessary to plan the design of the future premises. An important aspect of this issue is planning the placement of furniture, interior items, and household appliances. First of all, this is due to the need to optimally distribute electrical wiring and install it in the right places, including television ones. To properly connect a TV outlet, you just need to know its device, general principle work and installation procedure.

Coaxial cable device

The main difference that makes the difference between electrical and television outlets is the structure of the cable that connects to each of them. If the standard electrical wire consists of two or three separate cores, covered with insulation, which are connected to the corresponding contacts of the socket using bolted connections, then the design of the antenna cable is somewhat different.

TV coaxial cable is very easy to identify by appearance... It is a fairly thick wire of round cross-section with one solid conductive core made of copper inside. This center conductor is covered with a dense layer of insulation, on top of which is a screen of aluminum foil and thin steel wire. In most cases, PVC insulation is used as the outer protective coating of the cable.

Poor manufacturing or damage to any of the antenna wire elements leads to a significant deterioration in the signal quality, therefore, the laying of such lines should be treated with maximum responsibility.

Let's take a closer look at the device and purpose of the TV cable components:

1. Insulation. It is made of dielectric (usually polyethylene) and serves to exclude galvanic connection between the conductive core and the screen.
2. Screen. In any coaxial cable, this element is designed to prevent the emission of a high-frequency signal into space. Its other function is to protect against electromagnetic interference, to which the transmitted signal is very sensitive. In addition, two wires are required to allow the high frequency current to flow, so in this case the shield is used as the second conductor. Such a cable is called asymmetrically shielded.
3. Conductive conductor. It is the main part of the structure, since it serves to transmit an electrical signal.
4. The outer shell, which is designed to protect live parts from mechanical stress.

As can be understood from the design of the cable, connecting it to a television outlet is the connection of the center conductor and screen to the corresponding contacts. To understand the features of connecting such wires, it is necessary to briefly consider the device and the purpose of the main parts of the television outlet.

It should also be noted that when laying the antenna cable, do not place it in the immediate vicinity of electrical wires.

When connecting electricity consumers, sufficiently strong magnetic fields around the current-carrying conductors of the power wiring elements. Such fields can significantly distort the transmitted high-frequency TV / SAT signal. In addition, some household appliances are capable of emitting electromagnetic waves, which also affect the quality of the TV signal. And although at present such devices are becoming less and less, and almost all models of modern TVs are equipped with special filters that to one degree or another eliminate such an effect, the possibility of interference should be taken into account. For example, Legrand does not recommend placing power cables closer than 2 cm from the antenna.

As for the manufacturers of equipment used for the installation of electrical networks and information transmission systems, then, of course, one of the leaders in this market is the French company Legrand. Today it has representative offices in more than 60 countries of the world, and Legrand has been supplying products to our country since 1980.

Today, electrical stores offer a wide range of electrical and television Legrand sockets, switches, splitters, adders, amplifiers and other electrical products. The high quality of all Legrand devices has provided them with widespread recognition, however, when buying such equipment, you should beware of counterfeits.

Types of TV sockets

Depending on the purpose and use of the TV cable in the apartment in the wiring diagram, the sockets are divided into three main groups:

1. Solitary. The simplest and most common devices. Used to connect one TV set to a splitter or antenna.
2. Terminal. Used to install at the end - serial connection of sockets. This device should not be confused with single outlets. For stable operation of any of the Legrand TV sockets in the loop, there must be a certain characteristic impedance of the line, which is created by the terminal TV outlet.
3. Checkpoints. They are designed to be installed in the middle of a loop. The design of such devices provides for the connection of the antenna wire to them from both sides. One of these wires is incoming, it comes from the previous device connected to the splitter, and the other is outgoing (used to transmit the signal to the next outlet).

TV socket device

The main parts included in the design of any TV outlet are:

• TV socket housing (or printed circuit board), which is designed to connect the antenna cable to it. In a single socket, this part does not have any electronic circuits and only serves to ensure reliable contact between its elements.

• Front panel. This structural element of the device performs not only a protective, but also a decorative function. It can be chosen to match the interior of the room as much as possible. Depending on the purpose of the Legrand socket, it may have additional outputs, for example SAT and R. The TV-R-SAT socket is connected using one cable coming from a special combiner.

• Caliper. Serves for fastening all structural elements of the socket to each other, as well as for reliable fixation of the device in the installation box.

Connecting a TV socket

To connect such an outlet, you must adhere to a simple algorithm:

1. Prepare and install. For the installation of built-in devices, which are most common at the present time, it is necessary to drill a hole in the wall for the box. In addition, to lay an antenna cable suitable for such an outlet, you will have to gouge the wall. These works are associated with the appearance of a large amount of dust, so they are trying to coincide with the repairs in the apartment.
2. Prepare the cable. To do this, it is necessary to remove the layer of the protective shell about 3 cm from its end. Next, you need to carefully release the central conductor from the insulation at a distance of 1 cm from the edge.
3. Separate the housing from the bezel and support.
4. Connect the center conductor to the corresponding terminal on the housing using a screw connection.
5. Fix the cable screen with a special clamp, while ensuring their reliable electrical contact.
6. Attach the board to the support and fix the entire structure in a pre-prepared mounting box.
7. Install the front of the TV outlet.
8. Connect the antenna wire from the TV to the corresponding socket of the socket (TV-R-SAT)

It should be noted that there are designs of television outlets, the method of attaching the antenna wire to which may differ slightly. For example, Legrand sockets can use hinged or spring mounts. In any case, the basic principle of the connection remains unchanged.

Connecting a group of television outlets

It has long become normal to have two or more TVs in one apartment that can receive a signal from a cable television (TV) provider or satellite dish(SAT). In order to properly connect Legrand TV sockets, you can use the following diagram.

The diagram for connecting television outlets shown in the figure is called "star connection" and has a number of advantages:

• Slight signal attenuation.
• Since all the wires exit from one place, it is convenient to place the input box in it.
• There is no need to use an unnecessary number of loop-through sockets, which has a positive effect on the signal quality.
• The failure of one device does not in any way affect the quality of the work of all the others.

In this diagram, TV sockets are connected through a special device called a splitter. It is designed to split a TV or SAT signal into equal parts, transmitted to separate devices without losing its quality. These are not the only type of splitters used for routing antenna cables. Another common type of these devices is TAP. Their main difference is that the splitter divides the signal into equal parts by the number of subscribers and can be used as a signal adder. As for the TAP type splitter, it separates some part of the tv (SAT) signal and transmits it to the number of pins provided by the design.

When choosing a splitter, you should pay attention to its frequency characteristics. There are two main types of these devices:

1. Splitters designed for installation in digital television networks. They have operating frequencies not exceeding 1 GHz.
2. Splitters for satellite dishes (SAT). And the operating frequencies are in the range of up to 2.5 GHz.

Signal attenuation is another important selection criterion for these devices. If possible, you need to install a splitter that has this parameter as the minimum in the used frequency range.

If the signal coming from the provider or TV antenna is too weak or the TVs to which it is planned to be transmitted are too many, then you need to take care of installing an amplifier (for example, the SAT Legrand amplifier).

Another connection method is to use a serial circuit, an indispensable element of which is a through socket.

This scheme provides for a series connection of loop-through sockets, the last of which must be terminal. It should be noted that with such a connection there is some signal attenuation, so it is undesirable to use a large number of elements in it. The advantage of such a scheme can be called a significant savings in cable.

In this article, you will learn how to install and connect a Legrand TV outlet, as well as how to connect a TV outlet to a TV. In order not to waste your time, I will not talk about installing a socket box, since a whole article is devoted to this moment. We will determine that the socket box is already installed and a TV cable is connected to it.

To understand the very process of connecting a TV outlet, you need to tell a little about the device of a coaxial TV cable. I used a cable labeled RG-6U CCA (75 ohms).

1. PVC sheath
2. Outer conductor (shield), consisting of a metal braid and a foil covered with a layer of aluminum
3. Dielectric - insulation made of polyethylene or semi-air dielectric filling
4. Inner conductor represented by a single copper conductor

I would like to note that the TV cable can be presented in another design, for example, the screen can consist of copper wires, and the inner conductor can be stranded, but we will focus on this design.

2. Preparing a TV cable for connection

To connect to a television outlet, we need to prepare the cable connected to the socket. For this:

1 - Remove PVC insulation

2 - We make a twist from a metal braid ("screen"), and cut off the foil. As mentioned above, I use an RG-6U cable and it has a rather "liquid" braid (few wire elements), so I twist it. There are cables with a more massive braid, in such cases it is simply shifted to cut off the dielectric and expose the copper core. By the way, you don't have to cut the foil, sometimes it is left, and there are quite a few examples and schemes on the network where the foil remains. But as I understand it, the foil acts as an additional screen that protects the signal from interference (for example, when a TV cable is laid next to a power cable) and does not affect the quality of the connection.

3 - We expose the copper core, carefully removing the insulation (dielectric).

The step-by-step process of preparing a coaxial cable for a TV outlet is shown in the photo below:

The cable is ready, now you can go directly to the outlet itself.

3. Connecting a TV outlet

The Legrand TV outlet is shown in the photo below:

Back side view:

1. To connect the cable to the outlet, unscrew the bolt and open the metal cover:

The plastic housing of the TV socket must be removed prior to installation because it covers the bolt holes. In some of the photos below, there is a socket in the case. there the purpose is to show what and where we connect

2. Then we loosen the bolt, which is necessary to fix the inner conductor (copper core)

3. The copper rod of the TV cable must be inserted into the hole on the left, and the wire winding (screen) must be in contact with the body, I wrapped it around the cable insulation (see photo below):

Now that the TV outlet is installed, you need to prepare a cable to connect it to the TV.

4. Preparing a TV cable to connect a TV to a TV outlet

For this we need a piece of TV cable and a set of antenna adapters (photo below)

One adapter is needed to connect to the TV outlet and the other to connect to the TV. We measure the required length of the cable and cut it off. Then we need to prepare both ends of the cable for installing the adapters. They are prepared in the same way as the cable for connecting to a TV outlet is prepared (the process is shown in the photo below)

Now, using the ready-made cable, we connect the TV to the TV outlet. The connection process is complete.

The modern family now has a couple of televisions, set-top boxes, DVD players, computers. And not all of this abundance is ready to work without cables via Wi-Fi, and the signal power with a bunch of devices will simply not be enough. Therefore, the good old cable and TV outlet have a legal "residence permit" in an apartment or house.

If you are planning a renovation, then it's time to get puzzled by hiding all the cables in the walls so that the apartment does not resemble the lair of a cybernetic spider.

Therefore, let's figure out which sockets are needed for the TV. How many to take, where to put, what to look for and how not to get confused in tricky names.

The main types of TV sockets

Manufacturers divide TV antenna sockets into three types:

• single;
• terminal;
• checkpoints.

Single or simple TV socket

A single or simple outlet is always used independently and this is its main difference with a terminal TV outlet. If sellers in stores or would-be foreman tell you that there is no difference, look for other specialists and a retail outlet. Because, there is still a difference, and it is concluded in the following. A single TV outlet provides an attenuation of no more than 1.5 decibels of power, and the final one - as much as 10 decibels. That is, to put it simply, if you "stick" instead of a simple outlet with a terminal when installing a single point, your TV will show badly, with interference.

On a note! Therefore, remember, if you have 1 TV, 1 cable and 1 outlet, then it is always a simple single.

Looking ahead, let's say that in the connection scheme with a splitter (for several receivers), simple sockets are used.

Pass-through TV socket

A through television outlet is essentially a tee. It has 1 input and 2 outputs, one of them is for connecting the cable from the TV, and the second for the cable to the next pass-through or terminal outlet. These types of sockets are always installed together, one or more passable and at the finish - terminal.

We must say right away that we do not recommend getting involved in the installation of pass-through TV sockets. Each of them "cuts" the signal power stronger than the terminal one. So with low power and without installing an amplifier, a very weak signal will come to the last TVs in the chain. Limit yourself to four pieces in a bundle so as not to get into this situation.

Terminal TV socket

The terminal socket closes the chain of checkpoints, this is its main function. But you can put them on parallel assemblies as well.

The online store site offers a large selection of television sockets of all types

You can buy both products of leading European brands and Russian ones.

For connoisseurs of interesting design and for those who prefer a single stylist for all wiring accessories, TV sockets from the popular series are suitable:

• Legrand: Valena, Etika, Celian, Galea Life;
• GIRA: SYSTEM 55, E 22, F100;
• Schneider Electric: Sedna, Glossa, Odace, Unica;

Choose your series for exclusive home TV network equipment or a more democratic working version.

Connection diagrams for TV sockets

We figured out the types of sockets for a TV cable, now let's see the diagrams.

There are 2 main schemes for connecting a television cable and sockets - parallel, it is also a "star" and serial, it is also a pass-through. Here, in fact, there are no discoveries of America, the same principles as for the installation of any power grids. Television - differs only in lower voltage and refers to low current.

Connection of sockets for TV according to the "star" scheme

An apartment most often has one TV cable entry for connecting one TV receiver. But now few people have only one TV set, 2-3, or even more. And all of them must somehow be connected to the cable. This can be done through a splitter or splitter.

The device has an input and several outputs. Such a scheme with the use of a splitter is called the "star".

As you can see from the figure, there is also a signal amplifier in the circuit. Usually, the installed power is supplied on the input TV cable, which is enough for 1-2 receivers. But if there are more TVs, and the neighbors are also not lagging behind, the input value may not be enough. Alternatively, you can ask for extra capacity from the company that provides you with "television". They usually have reserves for this. Or be puzzled by the installation of the amplifier as in the picture.

Single or terminal TV sockets are suitable for star connection. Because from the splitter to each TV, its own cable will go.

One tip for choosing a type. If you plan to occupy all the sockets in the star scheme, both terminal and simple ones will do. If any remains unused - take the terminal, so that there is no interference on TV screens. The point is this. The termination receptacle has a "built-in" 75 ohm impedance, just like in line. And she doesn't care if the cable is plugged into the TV. The single socket does not receive "its" resistance for balance and borrows it from the TV. And when there is no connected receiver, the imbalance of the outlet with the line is reflected on the screens of other TVs in the form of all kinds of image distortions.

Pluses of "star" connection

• Convenient cable management with attachment in the junction box. It is good for installation and for checking, everything is collected at one point.
• A malfunction on one line does not destroy the entire system, because the lines are independent. If any incident with a cable or outlet happens on one branch, the rest will work as if nothing had happened.
• The television signal loses a minimum of power, and with an amplifier, it does not lose at all, but is additionally fed.

As for the significant cable consumption with such a scheme, it depends on how the wiring is done. A good master will “spread” the cable optimally and the difference with a single thread pull will be minimal.

Loop-through connection

We have the same initial data, one input and several TV installation points, which must be provided with TV signals. A loop-through daisy chain or "loopback" is the laying of one cable with inserts of loop-through sockets. And installation as the last outlet - terminal.

Pass-through sockets are made as a tee, they have an input and 2 outputs, that is, the socket receives the signal and divides it into 2 branches. On one you can put the cable from the TV, and on the other end of the cable to the next through socket. And the cycle repeats. The last in this chain is the terminal TV outlet, which closes the circuit. It is not even necessary to stick a telly into it, but it should be.

As already mentioned, it is undesirable to make such a scheme infinite, the signal power drops from point to point. And even with the installation of an amplifier, using the right cable and the right F-connectors, it can turn out that the latest TVs will show very badly. Despite the built-in automatic amplification and signal control system in the receivers.

Helpful advice! Before building any scheme, ask your provider how many TVs you can put on the line for free. Because, some service providers stipulate this, and exceeding the limit must be paid. And if you do it arbitrarily, you will run into a fine. There are also such tricks, however. So ask.

We have at the very least decided on the schemes, now let's talk about the installation.

How to install a TV outlet

Yes, in fact, just like any other, neatly and in its place.

Let's start with the height where to put the darling. Let's say right away - chase advisers, fans of European standards and with their "15 centimeters from the floor" in the neck. Our task is to hide the tails of the power and antenna cables behind the TV, so that it is beautiful and convenient. And according to the European standard, then you will have to hang the TV to the floor and watch from there.

Of course, there are also such fans of home cinemas, but there are far fewer of them than those who have a TV set hanging at a normal height.

Therefore, be guided by the edges of the TV screen so that neither sockets nor cords stick out. And if, in addition to the TV receiver, other devices are connected, install the sockets in convenient accessibility. Or you have to pretend to be a monkey, trying to reach the cherished food point.

How to choose a TV outlet by type of installation

In an amicable way, it is advisable to hide all cables in the walls, like ordinary power ones. Then there will be no tails anywhere and no damage to them. Hidden gasket - the best option and with the right cable, you will completely forget about its existence. If you have such a wiring done or you are just in the process of repairing, then take television sockets of hidden installation.

But if repairs are not planned, and there are suddenly more TVs, the gasket will be external. It can be done using skirting boards with channels and cable channels. In this case, overhead television sockets are needed.

Connecting a TV cable to an outlet is a fairly simple matter. But it has certain nuances, ignorance of which leads to complaints about their work.

The fact is that at the moment there are three types of TV sockets on the market. Each type of these wiring devices is designed for use in a specific circuit. And the wrong choice can lead to a significant deterioration in image quality. Yes and technical specifications sockets have certain differences that you should pay attention to.

But first, let's decide how to connect a TV outlet and what circuits are used for this? At the moment, there is a serial connection scheme, the so-called "star" and a mixed scheme. The mixed scheme is a derivative of the first two options.

Serial connection diagram of TV sockets

A sequential connection scheme is quite simple to implement, the price of its installation is an order of magnitude lower, but at the same time for a modern digital television it doesn't fit. Based on this, the scope of its application is constantly decreasing.

So:

• The essence of this scheme is as follows. From a signal source - this can be an antenna or an input signal cable TV, the first TV socket is connected. Another one is powered from this outlet, from the second third and so on to the number of outlets we need.
• To implement this scheme, two types of sockets are used - through and terminal. has two inputs for connecting a TV cable. The first is used to connect the incoming cable, and the second is used to connect the next outlet in the circuit.
• The last one in this scheme should be. It has only one entry for connecting a cable from the penultimate outlet in the circuit.

• The main feature of the feed-through and terminal outlets is the presence of special filters in them. The fact is that any TV, when receiving a television signal, generates a so-called reflected signal. It manifests itself in the form of noise or a superimposed image on an adjacent TV.
• In order to avoid special filters are used in the outlets. These filters attenuate the reflected signal. But there is also a certain nuance here. The fact is that such a filter extinguishes not only the reflected, but also the main signal.

Note! The drop in the signal level at the terminal and loop-through sockets by manufacturers in most cases is indicated separately. This parameter is called the signal drop per pass and usually ranges from 10 to 15 dB. It is clear that the lower this value, the better.

• Based on this, before connecting the TV cable to the outlet according to the loop-through scheme, you need to calculate the maximum possible number of outlets in the circuit. In this matter, we should start from the standards GOST 28324-89, which normalizes the signal level in our country.
• So for our country the standard is 57 - 83dB. For comparison, in Europe this standard is 57 - 74dB. And here it should be noted that more high level signal does not always mean better image quality. Often, an increase in the signal power above the normalized values ​​leads to the opposite effect.
• Based on this, many manufacturers recommend installing an additional amplifier for every 3 to 4 sockets.

Connection diagram of TV sockets "star"

Connecting a TV outlet can also be done according to the so-called "star" scheme. This scheme somewhat more expensive to implement, but it provides the same high-quality signal level at all sockets in the circuit. In addition, it practically does not limit us in their number.

• The essence of this scheme is as follows. From an antenna or other signal source, the cable is connected to a so-called splitter or multiplier. This device splits the signal and TV sockets are connected from it.
• The number of connected TV sockets depends on the number of splitter pins. It can range from two to 32 or more. Single sockets are used to connect to the splitter.

• The single socket has no features or built-in filters. In fact, this is an ordinary adapter, which, due to transient processes on switching, gives a signal drop of no more than 3dB.

• If the input signal is weak, then the instruction recommends installing an amplifier before the splitter. This will enhance the signal on all TV sockets. At the same time, this compensates for the drop in the signal level in the multipliers themselves. After all, it is in it that not only the signal separation circuit is located, but also the reflected signal suppression circuit.
• Mixed wiring is derived from star and series wiring.

Choice of TV sockets

Having an idea of ​​how to connect a TV outlet, you can proceed directly to their choice (see). Each type of socket has its own selection parameters. Therefore, in order to make our article more visual, we will summarize them in a general table.

Connecting TV outlets

After you have chosen the connection diagram, sockets and cable, you can go directly to the question of how to connect a TV cable to an outlet. The answer to this question largely depends on the type of cable attachment you choose, as well as the type of outlet.

• Before proceeding directly to the connection, you must correctly lay the cable and put it in the junction boxes. Like ordinary electrical wiring, this can be done in two ways - open and hidden.
• The open method involves laying the cable in skirting boards or special plastic boxes. In this case, do not allow contact between television and power cables. Otherwise, if the power cable is damaged, the TV cable may be damaged, which can lead to damage to the entire TV network and TVs connected to it.
• It is also impossible to allow joint laying of several TV cables in one box. This can result in noise and overlapping images.
• Before connecting the cable to the TV outlet in a hidden way, you should lay the grooves. Due to the greater thickness of the TV cable, their depth should be higher than for power wires. In this case, the rule on the inadmissibility of contact between power and television cables, as well as on the joint laying of several television cables, should also be observed.

Note! Joint laying of power and television cables is quite acceptable in the absence of contact. This is due to the fact that most televisions have power frequency interference cancellation.

So:

• The next important aspect is the correct stripping of the cable for the connection. The video on the pages of our site should help you with this.
• Now with regard to the connection itself. The most common is the cable screw connection. It involves fixing the cable to the socket with screws.
• In this case, after stripping, the cable is launched under a special mount. This must be done in such a way that the central core sits in its place of attachment. We should have a cable braid under a special mount. After that, we clamp one screw for fixing the central core and two screws for fixing the braid.

Note! With all types of fastening, it is critical that the braid does not intersect with the wire of the central core. Failure to do so will result in either simple interference or damage to the amplifier.

• Some manufacturers, for example lezard, produce sockets with clamping types of fastening. In this case, after stripping the cable, you do not need any tools.

• The essence of this method is reduced to fastening by means of a mechanical lock. To make the connection, you just need to open the lock, insert the cable into it and fix the central core in the right place. After that, the lock is closed, which provides not only fixing the cable, but also the required contact of the cable with the contacts of the socket.
• But at a TV outlet, the connection can also be carried out according to the quick installation scheme. Its essence boils down to the use of special clamps that provide reliable contact with the cable. At the same time, the operation of this connection method is identical to the scheme with a mechanical lock.
• Separately, I would like to note the connection of pass-through sockets. Indeed, in this case, two cables are attached to one outlet. It is very important here not to confuse incoming and outgoing cables. To do this, manufacturers usually put designations such as "entry" and "exit" or designation with arrows.

Output

As you can see, connecting a cable to a TV outlet is not so difficult. The main thing is to choose the right scheme and the type of sockets required for this scheme. Otherwise, this procedure should not cause difficulties even for people who are very far from telecommu- nications.

TV socket(TV socket) is a device designed to connect your TV to a television, satellite or radio network. Allows you to create aesthetic and easy-to-use connections (the cable is usually hidden in the walls or under the floor plinth). There is a possibility of parallel connection of two or more devices, as well as the possibility of increasing the number of network sections. TV sockets differ in connection method, manufacturer, appearance and operating frequency.

Think you've figured it out what is this device? Are you ready to buy a TV outlet? Do not hurry! Let's first figure it out in order to avoid misunderstandings. Below it is shown and described what types of TV sockets are, their device, as well as features that should be taken into account before choosing a television outlet.

Types of TV sockets

Television sockets, depending on the installation features, are individual, through and terminal.

Summarizing all of the above: pass-through and terminal sockets are used if and only if several TVs are used in the network receiving a television signal. Do you need a TV socket to connect a TV (one)? Buy a single socket! Do you need sockets for, for example, four TVs? Buy 3 incoming sockets and 1 end outlet. We figured out the types of television outlets, let's move on.

You can view the catalog of individual, pass-through, terminal TV sockets on our website.

TV socket device

Any TV outlet consists of several basic parts:

• corps (which is also called printed circuit board) required to connect to the antenna cable;
• a front panel that performs a protective and aesthetic function (can be selected in accordance with the general style of the room and personal design preferences);
• an adder required to connect a radio or satellite antenna in addition to the main one;
• support - which serves as the basis for fastening all parts of the socket into a single structure, as well as providing reliable fixation of the socket in the installation box.

Features of the choice of television outlets

Suppose you trust the well-known brand Legrand Valena (we fully support you in your choice). What parameters do the buyer need to know when choosing Legrand Valena TV sockets? On sale you can find sockets with clock frequency in the range from 5 to 2400 MHz. You should know that each type of signal (satellite, cable, radio) has its own operating frequency:

• cable TV or TV from an outdoor antenna works with a frequency from 45 to 1000 MHz;
• radio and television signals are transmitted with a frequency of 92 to 108 MHz;
• with a frequency from 950 to 2500 MHz - cable and satellite TV signal in combination with a radio signal.

Thus, the sockets should be selected according to the type of signal: R (radio), TV (cable or antenna TV) and SAT ( satellite television). Very often, one socket combines several jacks at once: TV + R, TV + SAT, TV + R + SAT. Thanks to this, signals of different standards and frequency ranges can be summed into a single cable to obtain the required signal in the corresponding socket.

As for manufacturers, here the buyer can choose a device from dozens of companies, the most famous of which are such as: Legrand, ABB, Shneider and others. Mechanisms like these are usually standardized and compatible with each other's hardware from third party brands.

Today on the market there can be found terminal, single and pass-through TV sockets. The listed products are characterized not only by the name, but also have a different design and purpose. Terminal and through-hole TV sockets, the difference of which is both in design and in application - these are just some of the types of those TV sockets that are available today.

Some unknowingly use them not quite correctly. Because of this, a negative attitude towards such electrical outlets is formed and is growing dissatisfaction with the quality of the TV signal... However, the correct installation of the desired type of socket is quite capable of correcting this situation. Therefore, in order not to become a victim of ignorance in the same way, we will talk in more detail about the types of TV sockets, and also determine the purpose for which each of them is designed and what it is needed for.

Types and schemes of use

To fully understand the specifics of installing TV sockets, as well as to understand where and what type is used, how to connect a TV outlet, you need to consider not only them design features, but also wiring diagrams. Since for wiring the coverage of a television signal, based on its frequency, various methods and connection schemes are used.

The structure of different TV sockets

Let's start with the differences that TV outlets have. It is conditioned various fields of application, which we will talk about below.

Let's start with the simplest TV socket - single. The specified socket is simply a contact connection, which makes it possible to connect the TV antenna cable to the network. According to the instructions of the manufacturing plants, the degree of signal drop in them does not exceed 1 - 2 dB, which is caused only by the transition resistances of contact mergers.

The terminal socket in this matter is an order of magnitude more complicated. In addition to the direct contact connection, it also contains a special circuit, which is intended to "extinguish" the reflected signal.

Description of the circuit

The bottom line is that each TV not only picks up the television signal, but also returns part of it to the network. The part that it returns is commonly referred to as the reflected signal. Compared to the main one, the power of the reflected signal is not so high, however, together with several TVs, this can cause significant interference.

Reflected signal can be seen on some other TV as a superimposed image or as noise. And in order to avoid this effect, a special circuit is used to suppress the reflected signal.

As a result, the terminal socket, with the exception of losses of 1 - 2 dB, which are caused by switching resistances, still suffers losses from 8 to 15 dB, which also cause the specified filter to work.

Be careful! GOST 28324–89 unambiguously states that the signal frequency should be 57–83 dB. Increasing, let alone decreasing, signal strength can lead to interference and a decrease in the proper image quality. As a result, it turns out that even the presence of one terminal socket significantly reduces the signal level.

But the device of the through socket is even more complicated. In addition to the filter and the contact connection itself, it contains one more contact interface for connecting other TV sockets. As a result of a decrease, the signal level at such an outlet can reach about 15 - 20 dB.

At the end of such a diagram the terminal socket is installed without fail. It differs from the checkpoint, as we have already found out, only by the presence of only one entrance. And its filter is entirely controlled with the reflected signal.

The main disadvantage of this connection method is the gradual deterioration of the signal in each subsequent outlet. At the same time, the cost of implementing such a scheme is significantly lower due to the lack of the need to purchase an antenna socket - a splitter.

Quite often and effectively the so-called hybrid or a mixed scheme. Its essence lies in the summing up of part of the sockets according to the pass-through scheme, and the part according to the "star" scheme. This makes it possible to save money with a fair removal of devices for connection from the splitter.

Connection algorithm

The question of how and in what cases a through socket should be used has been considered in detail, now you can proceed to the task of connecting it. It is quite possible to perform this procedure on your own, and this does not require special tools or skills.

Be careful! Mount TV cable together with power wires is prohibited. Since damage to the power wiring can lead to a large voltage on the TV cable. And this, again, will lead to malfunction of all TVs. Moreover, the power cable can also interfere with the broadcast.

Now we proceed directly to connecting the TV outlet.

After completing all these steps, you can start connecting the next socket.

It should also be mentioned that numerous manufacturers, in an effort to speed up and facilitate the installation process, have used all kinds of folding locks and spring clips. But still, the process of installation has not really changed from the innovations. The only thing they were able to eliminate was the need to use a screwdriver.

As you can see, the installation process of terminal, loop-through or single TV sockets is not so laborious. In this matter, the main condition is to choose the right the outlet itself and its connection diagram... We hope that our article has guided the reader in this matter, and now anyone can easily choose and connect exactly the TV outlet that suits a particular circuit.
