Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an embedded BS booster.

[Conventional technology] Conventional BS boosters have been of the exposed type.

[Problem H to be solved by the invention] Since the S booster uses a plug outlet for power input, it requires an AClooV outlet nearby. In addition, in order to supply power to the UV booster,
This requires a current-passing type distributor, complicating the design of the receiving system. Moreover, since it is an exposed type, there is a problem that when it is attached to a wall, the protrusion is large and ugly.

The present invention has been made in view of the above points, and its purpose is to enable easy embedded installation using a ready-made embedded switch box, to perform so-called advanced wiring, and to provide a power source for UV boosters and BS converters. To provide an embedded type BS booster that can be easily supplied.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a power supply means for supplying DC power via coaxial cables connected to a BS converter and a UV booster, respectively, and a BS converter. Both sides of the booster body, which has built-in signal amplification means for amplifying signals from A locking protrusion is provided for this purpose.

[Operation] The present invention provides an embedded switchboard/socket that allows advance wiring by locking the locking protrusions on the locking portions of the mounting frame attached to the ready-made multiple embedded switchboard/socket on both sides of the booster body. The booster body can be installed and stored, so there is no need for a power outlet near the installation location like in the past, and it doesn't protrude into the wall like an exposed type, so it doesn't look ugly, and it also makes it easier to use for BS converters and other devices. Since direct current power can be supplied to the UV converter from the built-in power supply means via the coaxial cable, the receiving antenna system can be easily designed without requiring a current passing type distributor or the like as in the conventional case.
