Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a booster device for amplifying a television signal or the like received by an antenna and then supplying the amplified signal to a receiver, and more particularly, an amplification part for amplifying a received signal and a power supply part of the booster device are detachable. It can be freely separated,
The present invention relates to a power-source-separated booster device that can be used as an integrated type or can be used separately.

[0002]

2. Description of the Related Art Television signals or CATV received by an antenna
Conventionally, it is conventionally possible to mechanically separate the booster device for amplifying the upper and lower signals into a power supply part and an amplifying part so that both can be used integrally or both can be used separately. More widely known. For example, Japanese Utility Model Application Laid-Open Nos. 57-31885, 57-53695 and 57-2741 disclose a structure in which a power source section and an amplifying section can be mechanically separated.

In these prior arts, a housing in which a power supply circuit is housed (also referred to as a power supply section) and a housing in which an amplifier circuit is housed (also referred to as an amplifier section) are detachable structures. When installing the entire booster device indoors, both housings are joined to form an integrated type, and when installing the amplification unit outdoors, the two housings are separated and the amplification unit is installed near the outdoor antenna. The power supply is installed indoors, and the two are connected by a cable.

[0004]

The above-mentioned conventional technique is
It is only related to the mechanical structure of joining / separating between the two housings, and there is only a description that electrical connection between the power supply unit and the amplification unit is performed by a power supply line. For this reason, when it is used as an integrated type indoors, the structure in which both housings are mechanically joined becomes bulky, and in addition to this, a transfer is made to electrically connect the power supply section and the amplification section. Wiring work is required. If this electrical wiring cable is exposed to the outside of the housing, there is a problem that the appearance is spoiled.

Further, electrical connection is made when the amplifying part of the booster device is installed outdoors apart from the power supply part and when the amplifying part of the booster device and the power supply part are used indoors side by side. If the lines are different, there is a problem in that the connection can be erroneous when a general user installs the line by himself.

It is an object of the present application to provide a power source separation type booster device in which a power supply unit and an amplification unit can be used by arranging them side by side or by separating them with a simple structure. Another purpose is to send power from the power supply unit to the amplification unit at the same time as receiving the signal from the amplification unit and send the signal to the receiver of the next stage through the power supply unit when the amplification unit is far away. Another object of the present invention is to provide a booster device having a separate power supply unit. For other purposes, even if the amplification unit and the power supply unit are combined and integrated, or even if the amplification unit and the power supply unit are separated from each other, the electric connection state between them is the same, and even an amateur can make an error-free connection. An object of the present invention is to provide a booster device with a separated power supply unit. Another purpose is to combine the amplifier and the power supply unit together so that the power supply unit and the amplification unit can be electrically connected near each other without exposing the electrical wiring to the outside, and the appearance is not spoiled. An object of the present invention is to provide a booster device with a separated power supply unit. Other objects and advantages will be readily apparent from the drawings and the following description related thereto.
