Description

Description: BACKGROUND OF THE INVENTION The present invention relates to an input line plate with a mixer in which a so-called guard plate is provided with a mixer for mixing an output signal from a BS converter and a reception signal in the UHF or VHF band. Things.

[Conventional technology]

Conventionally, when a radio wave received by a receiving antenna is drawn indoors, there is a rainproof incoming line cover. This rainproof cover has a configuration in which a coaxial cable is drawn directly from outdoors to indoors.

[Problems to be solved by the invention]

However, since the conventional rainproof cover does not have a structure in which outdoor and indoor wiring can be separated by a connector or the like,
It is difficult to separate indoor and outdoor wiring, and with the recent spread of satellite broadcast receivers, the need to mix the output signal of the BS converter with the received signal in the UHF or VHF band has increased. However, I could not respond to this.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and the invention according to claim 1 and the invention according to claim 2 allow the indoor wiring and the outdoor wiring to be separated from each other. The wiring to the outside can be easily connected. In addition, the output signal of the BS converter can be mixed with the UHF or VHF band reception signal. It is an object of the present invention to provide an inlet plate with a mixer which can be converted.

A third object of the present invention is to provide an input wire plate with a mixer that can separate the mixers to be housed and can expose and dispose the mixers independently.

[Means for solving the problem]

In order to achieve the above-mentioned object, the invention according to claim 1 provides a guard plate body including a base frame and a cover having one end pivotally supported on the base frame so as to be openable and closable, and a BS housed in the guard plate body. Converter output signal and UH
It consists of a mixer that mixes F and VHF band received signals, and a mounting frame that is arranged on the back of the base frame and attaches the plate body to the embedded box, and connects each of the signals to the mixer. An F-type plug is provided as a connection portion, and a connector for indoor wiring is provided so as to face a window hole of the base frame.

The invention according to claim 2 provides a guard plate body including a base frame and a cover having one end pivotally supported on the base frame so as to be freely opened and closed, an output signal from a BS converter housed in the guard plate body, and UHF and A mixer for mixing the received signal in the VHF band, and a mounting frame disposed on the back of the base frame and mounting the plate body to the buried box, and a connection portion for connecting the signals to the mixer. A connector consisting of a connection fitting for inserting and connecting the core wire of a coaxial cable and a holding fitting which is pivotally supported so as to be openable and closable and presses and fixes a shield portion of the coaxial cable, and faces a window hole of the base frame. Is provided with a connector for indoor wiring.

According to a third aspect of the present invention, in the first or second aspect, the chassis of the mixer is fitted into the opening window of the mounting frame through the window hole of the base frame, and the locking projections provided on the inner edges on both sides of the opening window are provided. It is detachably engaged with engaging holes formed on both side surfaces of the chassis.

[Action]

According to the present invention, it is possible to arrange the mixer outdoors by taking measures against rain by the guard plate body, and furthermore, the BS
Since the F-type connector or connector is provided to connect the output signal from the converter and the UHF or VHF band reception signal, outdoor wiring and indoor wiring can be performed separately and separately. . Then, since the wiring on the indoor side and the wiring on the outdoor side are connected via the mixer, and an output in which each signal is mixed can be taken out, only one wiring on the indoor side is required. Can be simplified.

According to the third aspect of the present invention, since the mixer and the mounting frame are removably engaged with each other, the mixer can be independently used as an exposed arrangement type mixer.
