The principles of installing sockets for TV and conventional connectors are similar, since in both cases the same type of socket is used. There are only minor differences in the way of installation work. In this article, we will take a closer look at how to connect a TV outlet.
Varieties of television sockets
There are two types of television outlets: final (terminal) and through. Also, the connectors are classified according to their purpose: for terrestrial TV (designated as TV), for radio (R), for satellite TV (SAT). In addition, there are combined types of sockets on sale: TV (45-1000 MHz), TV + R (92-108 MHz), TV + SAT (950-2500 MHz), TV + R + SAT.
Advice! It is desirable that the socket be the same color as the power connectors - this will make it easier to fit into the interior. If the sockets are installed in single block, then not only the color, but also the manufacturer of the devices must be the same.
The final connectors are so named because they are the final node on the network. This type of TV sockets is distinguished by a high-definition signal, no interference due to a characteristic impedance of 75 ohms. Terminal connectors can work with several standards: both individually and in combination (TV, TV + R, TV + R + SAT).
Another type of connectors is the TV through socket. Such devices are used to receive a signal and further transport it to other connection points. Signal transmission between the sockets is carried out over a coaxial cable. The device is equipped with a pair of jacks (one at the input and one at the output). The TV is connected at the input, and at the output there is a wire going to another consumer. In this case, the last outlet in the diagram is always the final one. Pass-through connectors are not used for constructing circuits in which the satellite signal due to technical incompatibility with most of the solutions.
The loop-through TV socket does not differ from the terminal with front panel... But on the back there are two connectors with arrows input and output Connection diagrams
There are many schemes for connecting a TV connector. A splitter is used to process the signal. This device outwardly looks like a small box and performs the function of splitting the signal. As well as in telephone lines, when transmitting digital electrical signals you cannot do without their separation.
The principle of operation of the splitter is to divide the signal into identical packages... Further, the divided segments are transmitted to the input part of the television connectors. The splitter is designed in such a way that for all TVs receiving a signal, regardless of their number, a signal of equal quality will be transmitted. As a result, within the same apartment, there is no sense in a separate antenna for each TV.
Connection can be done in one of two ways:
- Asterisk pattern when removed old cable, and a new one is routed through the splitter.
- Loop circuit.
Below we will figure out how to connect an outlet, while paying attention to the advantages of the schemes under consideration.
Asterisk scheme
This circuit uses a splitter to split the signal, split it into packets, and amplify. The device is placed at the cable entrance to the dwelling from the entrance. Further, the antenna conductors are wired to consumers. Installing a TV outlet using such a simple technology is most often used, since the splitter provides a number of advantages:
- The cable is located in a technically protected place, which is important both during installation work and during further preventive examinations.
- The signal is stable.
- The split signal packets are delivered uninterruptedly to all TV receivers in the apartment.
Daisy chain connection
This method of mounting a TV outlet involves the use of a loop. The main cable is directed to any of the TVs available in the house, and then wiring to other receivers is carried out directly on the connector. The wiring is a branch into two or more parts (depending on the number of TVs available).
Connection in this way is called daisy chain. In this case, the connectors connected by a loop must be pass-through, except for the last one, which is the terminal one.
The daisy chain scheme allows you to save on cable consumption, but it also has disadvantages. The disadvantage of the loopback system is that the quality of the first receiver will be higher than that of the subsequent ones. However, with sufficient TV signal strength, the difference will be almost imperceptible. In addition, one should take into account the fact that modern television technology equipped with the ability to amplify the signal, and this happens in automatic mode.
Daisy chain connection through TV through sockets So, the uneven distribution of the signal in in this case can be considered an insignificant drawback. Other disadvantages of the loopback system include the following:
- The scheme, where there are through and terminal TV outlet, will cost more than the standard "asterisk" scheme.
- In the event of an open circuit, all subsequent consumers are deprived of the television signal.
Installation on the example of a Schneider socket
As an example, let us analyze the installation of a through socket outlet from the French company "Schneider Electric" (model tv socket rj45). The task is to connect two TVs to one cable in a loop-through loop.
When installing an outlet for a TV cable, we provide for a small surplus of the cable itself - it should go out of the mounting box. Next, we clean a small section of the insulating material on the cable. At the same time, we keep the central core and the shielding braid intact.
We start by removing the front panel, slightly unscrew the holding bolt. This is to ensure free cable exit through the hole.
There are arrows on the connector housing. We insert the cable to the end in the direction indicated by the arrows. Then we press the cable with the clamping screw (tighten it). The cable must be securely fastened, but the screw must be tightened with care so as not to pinch the line. We perform exactly the same manipulations with the second end. We install the connector in such a way as to avoid kinks on the cable.
Note! Before installing the television outlet, you should inspect the wire fixing area for the possibility short circuit main conductor with braid.
When the cable is inserted and secured, put on the bezel. The panel is fixed using special branded latches. We check with a building level the accuracy of the horizontal installation of the connector. If everything is in order, we finally fix the panel with the fixing bolts and close it with a frame.
Lezard Connector Connection
Sockets from the Lezard company are inexpensive and differ good quality... However, when choosing Lezard products, you need to take into account the presence on it printed circuit board... The fact is that the boards are equipped with a component such as a capacitor. This part is located next to the center conductor retainer and the connector for cable connection... The capacitor is impervious to the supply voltage that must be applied to active antenna... Therefore, these connectors are only suitable for passive antennas.
If, nevertheless, there is a desire to adapt such an outlet to an active antenna, instead of a filtering capacitor, you need to put standard conductor... This is done by shorting and sealing a piece copper wire instead of a capacitor.
The very connection of the TV socket consists in the installation of the signal conductor of the TV cable in the central socket terminal. You also need to fix the screen with a bracket.
Note! Do not allow short circuits of the main conductor passing the signal to the braid. Otherwise, the screen will be broken, protecting from the loss of the television signal in the cable.
Legrand connector connection
The TV socket from the French manufacturer "Legrand" is distinguished by the convenience of connection, but it is also quite expensive.
When connecting the connector, we fix the central cable core in a special spring clip. We press the foil braid to the body using a hinged mount.
Remove the attachment cover that covers the coaxial cable connection areas. To do this, carefully pry off the cover with a screwdriver, thereby releasing the latch.
We remove the outer insulating layer and the inner dielectric material of the cable approximately one centimeter in length. We direct the cable into the connector, and fix the copper core with a self-clamping terminal.
Note! Contact of the braid with the socket housing is achieved thanks to the plate, which is connected to its outer insulator, firmly pressing against the cable shield.
When the cable is connected to the connector, we install the latter in the socket. We fix the socket with a pair of self-tapping screws. Next, clamp the screws with the spacers of the socket clamps. We tighten the self-tapping screws of the socket box until it stops. We put the front panel of the connector in its place. The TV socket on the wall is installed and ready for use.
A television socket is a special device that, depending on the specific type of construction, is capable of performing various tasks. In particular, by means of sockets, you can connect a number of devices in parallel, increase the network area, etc.
Types of sockets
The shops trading network Leroy Merlin offers its customers television sockets of the following types:
- Pass-through devices are equipped with an input and two outputs, one of which can be connected necessary equipment, and to the other - the next outlet. When laying the network, it must be borne in mind that each outlet leads to the fact that the signal becomes somewhat weaker, and therefore the installation is too a large number similar devices impractical. Pass-through models are needed in order to connect several devices at once, they are operated in most cases in combination with terminal sockets.
- Terminal sockets complete the network, improve the quality of the television picture, for which the characteristic impedance is at the level of 75 ohms.
- Individual sockets also complete the network, but do not have the same impressive resistance as their wave counterparts, which can cause problems with the image.
Selection and installation principles
When choosing an outlet, be sure to find out about it. operating frequency... Likewise, if you plan to connect to the product in the future additional devices eg modem, select models with dedicated inputs.
When installing the socket on the wall, it is better to use special boxes that reduce the mechanical load on the element and increase its durability.

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 den 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
| TV socket single Legrand Etika | TV socket single Legrand Valena | TV socket simple Schneider Electric Glossa | TV socket simple Schneider Electric Unica |
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 socket 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
| TV socket Legrand Etika through passage | TV socket through Legrand Valena | TV socket through Schneider Electric Glossa | TV socket through Schneider Electric Unica |
A straight-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 outlets are always installed together, one or more passable and at the finish - terminal.
We must say right away that we do not recommend getting carried away with the installation of pass-through TV sockets. Each of them "cuts" the signal power stronger than the terminal one. So when weak power and without installing an amplifier, the last TVs in the chain will receive a very weak signal... Limit yourself to four pieces in a bundle so as not to get into this situation.
Terminal TV socket
| TV outlet terminal Legrand Etika | TV outlet terminal Legrand Valena | TV outlet terminal Schneider Electric Sedna | Terminal TV socket Schneider Electric Unica |
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 from leading European brands and Russian ones.
For connoisseurs interesting design and for those who prefer a single style 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;

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 connection diagrams tv cable and sockets - parallel, it is 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 using a splitter is called "star".
As you can see from the figure, there is also a signal amplifier in the circuit. Usually, the input TV cable is supplied installed capacity, 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 some 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 a line. And she doesn't care if the cable is plugged into the TV. Single socket did not receive "her" 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 distortion.
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. Good master"Spreads" 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. Checkpoint sequential circuit or "loopback" is the laying of one cable with cut-out 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 terminal tv socket, which closes the contour. 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, when using correct cable and required F-connectors it may turn out that 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 those who feed and antenna cables for the TV, so that it is nice and comfortable. And according to the European standard, you then 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 much 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 the hidden installation television sockets.
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.

How to choose a TV cable
Unambiguously in terms of the quality of signal transmission and the strength of the insulation. The attenuation in the cable should be minimal, and the insulation should reliably protect the core from external influences. For hidden styling, only representatives are better suited. These are SAT 703, SAT 50, DG113, F1160BVM COMMSCOPE (RG-11) cables.
| SAT 703 cable | SAT 50 cable | DG113 cable | F1160BVM COMMSCOPE cable (RG-11) |
They are single core copper cables with an insulating foam layer and a durable shell that will feel great under plaster.
For outdoor installation, RG-6 cable is suitable, but if you want to get more quality signal, choose cables from the first list. The RG-6 cable can be used to connect the TVs themselves to the sockets.
How to connect a TV cable to an outlet
The supply antenna cable is connected to the socket in a special socket with a screw. At the same time, the central core is carefully released from the insulation and fixed in the hole. For better fixation with the second screw, through a special plate, a part of the braided cable is fixed. This ensures that there is no movement and protects the central core from fracture.
Helpful advice! If you are far from an electrician, then it is better not to lay the television cables yourself. Entrust the work to the specialists, they know all the tricks and subtleties. For example, they will not forget that distances must be maintained between the antenna cables and the supply cables. Lay at least 3 centimeters apart. Otherwise, there will be interference, especially on cables like RG-6 and similar.
Mysterious socket TV RD SAT and its brothers
In addition to ordinary TV sockets, manufacturers offer products with mysterious names tv rd sat, tv fm sat, tv sat, TV-RD, tv + rj 45. In fact, there is nothing mysterious about them, and these are simply combined sockets for connecting 2- 3 different receivers.
It's no secret that providers most often offer sets of terrestrial television, radio, satellite and internet in addition. If you don't want to pull a bunch of cables into the apartment, then a mixer block is placed in the switchboard on the site. It collects signals from several antenna cables to one outgoing one, and it is brought into the apartment. And then to separate the frequencies of different broadcasts, a combined socket is installed to connect a group of receivers.
Such sockets will also come in handy in houses with cable networks. There, adder blocks can be one at the entrance and one cable is pulled to the consumer at once. For separation different frequencies signal and you need a combined socket.
Let's look at the intricacies of names using the example of Legrand products
TV-RD-SAT sockets
TV-RD-SAT sockets can be found in the Valena and Galea Life series. They are designed to connect a TV (TV), radio (RD) and satellite receiver(SAT). Suitable for cable networks, by type there are checkpoints or terminal.
| Legrand Galea Life TV-RD-SAT socket through | Legrand Galea Life TV-RD-SAT socket outlet |
TV-FM-SAT sockets
TV-FM-SAT sockets are present in the Celiane and Valen series. They are used as single TV cables in home wiring. They are connected according to the "star" scheme, directly connecting to the splitter along one line. In the socket itself, you can turn on a TV and radio receiver, as well as a satellite receiver.
The main difference that characterizes a television outlet from electrical outlet is the structure of the cable connected to the product. Coaxial cable consists of one solid core, enclosed in dense insulation with a screen made of foil-clad metal and thin steel wire, on top of the whole structure is closed with an outer protective sheath made of PVC insulation.
Important: The shield in the coaxial cable, also called asymmetrically shielded, has the function of protecting against high frequency signals into the surrounding area. It prevents interference, to which the signal received by the object is sensitive. Besides protective shield serves as a second conductor to ensure the flow of high-frequency current through the cable.
According to their functional purpose, television sockets are divided into three main types - these are:
- single sockets, their resistance is characterized by an insignificant value of internal resistance;
- pass-through, installed in the middle of the loop, the cable is connected to these sockets from both sides,
- end they are characterized by large value internal resistance;
Single sockets refer to simple type and are considered a common wiring product, are used to connect television receiver... Work is carried out through a splitter or crab from one antenna.
A loop-through socket is used to connect two or more TVs, the connection is made by dividing the TV signal for each TV. The operation of the product is based on the supply of one cable from the antenna, the other cable leaves the outlet and goes to the TV.
The terminal socket is used to terminate the multi-socket television network... Main characteristics large internal wave impedance up to 75 Ohm, it is equal to the wave impedance in the television line, due to this it decreases negative impact television receivers on top of each other, as a result of improving the quality of the television signal, the picture of the television image is improved. 
Fig. No. 1. Front panel of the television outlet
Operating frequencies typical for combined sockets
A television receiver (TV) operates at frequencies from 5 to 862 MHz.
Radio receiver ( FM ) its range is from 87.5 to 108 MHz.
Satellite television ( SAT ) from 95 to 2400 MHz.
The scheme of the terminal socket "star" - TV-RD-SAT, terminal or terminal sockets are used to improve the picture quality to get rid of interference, switching channels on one TV does not affect the image of another TV receiver.
Features of the design of television sockets
Modern TV sockets
Currently, designs have been created for television outlets that combine various functions Is the connection of the television consumer ( TV) , radio points (FM) and satellite (SAT) receiver.
By schemes : TV— RD— SAT; TV— FM— SAT; TV— RD, for three and two output connectors, a socket that includes the abbreviation in its marking RD, serves as a terminal socket. Connection is carried out according to the topology "star" and "loop"
Features of the device of television sockets
Modern TV sockets in their design imply the presence of a main spring or screw terminal contact for connecting the central core of the television cable. The auxiliary terminal (special bracket) is used to connect the braided shield. Feed-through sockets have two pairs of terminals for connecting incoming and outgoing cables.
Modern sockets from Legrand, ABB and other European brands do not require when connecting additional training TV cable, it is enough to insert the bare core into the contact terminal and it will automatically clamp it, puncture the main insulation and clamp the cable. The connection turns out to be very reliable.

Star scheme
The TV socket for this circuit is used with one input and multiple outputs for 2; 3; 4 outputs. The input signal must have sufficient power to provide a good TV signal, otherwise the picture on the last TV set will be poor. 
Rice. No. 3. Star scheme.
To amplify the signal, apply tv amplifier, which will provide an increase in the signal power, it is recommended to install it next to the TV signal source, directly in the switchboard or next to the input of the TV cable into the apartment.
Recommendation: when installing a "star" television scheme. Do not lay a branch and incoming cable, interference may appear, and the quality of the TV signal will deteriorate. The "star" scheme is the best option for connection digital television... NV receivers are connected using a router, the function of which can be a digital splitter or hub. It can be a set-top box SD, a CAM-model receiver, it is suitable for receiving an IPTV signal.
Loop circuit (loop-through)
The circuit uses series-connected feed-through sockets and terminal socket... There is practically no signal quality degradation in the circuit, the quality depends on the correct connection of the television cable to the F-connector. Using this connection makes it possible to connect three TV sets from loop-through sockets and two more from a single (individual) and dead-end outlet. 
Rice. No. 3 Loop-through circuit for connecting television sockets.
The wiring of the "loop" and "star" circuits is carried out through a splitter, which serves as a separator of the TV and SAT signal into identical parts without loss of signal quality; the splitter is also used as a signal adder. In addition to the splitter, the TAP splitter performs a similar function, it divides the signal into several outputs. Splitters used for television receivers use an operating frequency of 1Hz, devices that perform a similar function for satellite receivers have frequencies up to 2.5GHz.

Before proceeding renovation works in the apartment, it is necessary to plan the design of future premises. An important aspect of this issue is planning the placement of furniture, interior items, as well as household appliances... First of all, this is due to the need to optimally distribute the electrical wiring and install it in the right places, including television. 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 is 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.
Television coaxial cable is very easy to identify by outward appearance... It is a fairly thick round wire 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. As an outdoor protective coating cable in most cases, PVC insulation is used.
Poor manufacturing or damage to any of the elements of the antenna wire leads to a significant deterioration in the quality of the signal, therefore, the laying of such lines should be treated with maximum responsibility.
Let's take a closer look at the device and purpose. component parts tv cable:
- Insulation. It is made of dielectric (usually polyethylene) and serves to exclude galvanic connection between the conductive core and the screen.
- Screen. In any coaxial cable this element is designed to prevent the emission of high frequency signal into space. Its other function is to protect against electromagnetic interference to which he is very sensitive transmitted signal... In addition, to ensure the flow of current high frequency two wires are required, so in this case the shield is used as the second conductor. Such a cable is called asymmetrically shielded.
- Conductive core. She happens to be main part design, since it serves to transmit an electrical signal.
- 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 peculiarities 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 Appliances have the ability to radiate electromagnetic waves that also affect the quality of the TV signal. And although at present such devices are becoming less and less, and almost all models modern TVs are equipped with special filters, to one degree or another eliminate such influence, nevertheless, 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.
- 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 elements of the socket structure 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:
- 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 chisel 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.
- Prepare the cable. To do this, you need to remove the layer 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.
- Separate the housing from the bezel and support.
- Connect the center conductor to the corresponding terminal on the housing using a screw connection.
- Fix the cable screen with a special clamp, while ensuring their reliable electrical contact.
- Attach the board to the support and fix the entire structure in a pre-prepared mounting box.
- Install the front of the TV socket.
- 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 connection principle remains unchanged.
Connecting a group of television outlets
It has long been normal for two or more TVs in one apartment to receive a signal from a provider. cable TV(TV) or from 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 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 according to 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.
