DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a serial unit for TV listening.

[0002]

2. Description of the Related Art Conventionally, a series unit for TV listening, especially B
There is an S series unit in which a switch box mounting frame is integrated, but in this conventional example, a plate is attached from the surface and an outlet is directly exposed to an instrument exposure window provided on the plate. Was something.

[0003]

Therefore, this type of device has a poor image of a wiring device having a large plate thickness and a large dignity. The present invention has been made in view of the above-described problems, and its object is to provide a wiring device having a solid dignity corresponding to a wiring device plate including a lower frame, a plate frame, and a decorative cover. It is an object of the present invention to provide a serial unit for TV listening that can be handled.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a lower frame having a window in the center and an opening window attached to the surface of the lower frame and corresponding to the window. It is to be attached to a wiring device plate composed of a provided plate frame and a decorative cover fitted to an opening window of the plate frame, and at both ends of the series unit chassis, the back surfaces of both ends of the lower frame are fixed. A mounting piece having a mounting hole for the switch box is integrally formed with a low step with respect to the series unit chassis surface, and a lower frame window hole and a plate frame opening window are formed on the serial unit chassis surface. And an outlet that is exposed to the surface from the appliance exposure hole of the decorative cover.

[0005]

According to the TV series listening unit of the present invention, both ends of the lower frame are fixed to the mounting pieces at both ends fixed to the switch box, and the outlet on the surface of the series unit chassis is connected to the window hole and the lower frame. It is exposed to the front side from the opening window of the plate frame. At this time, since the surface of the series unit chassis is positioned on the front side by an amount corresponding to the step with the mounting piece, the thickness of the lower frame and the plate frame can be absorbed, and the outlet for the conventional plate can be used. Next, if a decorative cover is fitted into the opening window of the plate frame and the outlet is exposed through the device exposure hole of the decorative cover, the mounting of the wiring device plate including the lower frame, the plate frame, and the decorative cover is completed.

Together with the series unit chassis 1.

A side body 3E in which a core receiving blade 6 of a coaxial cable is disposed in a groove 3F from a cutout hole 1E of the side plate 1B on the side of the main body 3A of the outlet 3 along the surface of the side plate 1B.
Is provided. The core wire receiving blade 6 has a configuration in which the core wire is sandwiched between two spring pieces.
It is connected to a circuit in the series unit chassis 1 via E.

The side plate 1B is provided with a holding member 7 for contacting the exposed braided wire of the coaxial cable and fixing the coaxial cable to the side plate 1B, corresponding to the core wire receiving blade 6. The holding member 7 includes a holding piece 7A for holding the coaxial cable and a fixing piece 7 having a hole through which the screw 8 is inserted.
The coaxial cable inserted between the holding piece 7A and the side plate 1B is held down and fixed by screwing the screw 8 into the screw hole 9 of the side plate 1B through the coil spring 10 to fix the coaxial cable.

At both ends of the series unit chassis 1, mounting pieces 11 are integrally provided so as to be one step lower in the back direction than the surface of the series unit chassis 1. The mounting pieces 11 correspond to both ends of the mounting frame for the switch box. The mounting pieces 11 are provided with mounting holes 12 for the switch box and L-shaped holes 13 for mounting hardware for the wall panel. A screw hole 15 for fixing the frame 14 with a screw is provided. At the side ends of both sides of the mounting hole 12, a rising piece 16 which is bent and turned upright is integrally formed.
The edge on the side of the attachment piece 11 of the extension piece integrally extended further inward from the edge forms a locked portion 19 of a locking claw 18 of the decorative cover 17 described later. Further, the side edge of the anti-attachment piece 11 of the extension piece is inclined toward the series unit chassis 1 to serve as a guide surface 19A of the locking claw 18.

A wiring device plate 20 composed of a lower frame 14, a plate frame 21, and a decorative cover 17 is mounted on the BS series unit assembled as shown in FIGS. At the time of mounting, first, the back surface of both ends of the lower frame 14 is made to correspond to the front side of the corresponding mounting piece 11, and the fixing screw 2 attached to the both ends of the lower frame 14 is attached.
2 is screwed into the screw hole 15 to fix the lower frame 14.

At this time, the portion including the mounting hole 12 of the mounting piece 11 and the portion of the series unit chassis 1 face the window hole 23 of the lower frame 14, and the outlet 3 is opened.
Protrude more to the front side. FIG. 4 is a front view showing this mounting state. Next, locking claws (not shown) formed on the back surface of both sides of the plate frame 21 are inserted and locked into locking holes 24 provided on both sides of the lower frame 14, and the plate frame 21 is moved to the lower frame. 1
4 Fix to the surface. At this time, the plate frame 21 having a thickness
The outlet 3 attached to the surface plate A of the series unit chassis 1 having a step with respect to the attachment piece 11 protrudes from the opening window 25 of the plate frame 21 to the surface side.

Finally, the decorative cover 17 is fitted into the opening window 25 of the plate frame 21 while fitting the outlet 3 to the appliance exposure hole 26 provided at the center of the decorative cover 17 to expose the outlet 3 on the surface. At this time, the makeup cover 17
Locking claw 1 formed integrally on the back surface on both sides of both ends
8 is inserted into the opening window 25 and the window hole 23, and the locking claw 18 is further guided to the locked portion 19 along the guide surface 19A and locked by the locked portion 19, and the decorative cover 17 is removed. Fix it.
With this fixing, the mounting of the wiring device plate 20 is completed.
FIG. 5 is a cross-sectional view showing a state in which the wiring tool plate 20 is attached.

[0014]

According to the present invention, the series unit for TV co-listening is provided with the both ends of the lower frame fixed to the mounting pieces at both ends to be fixed to the switch box. When exposed to the front side from the opening window of the frame, the surface of the series unit chassis is positioned on the front side by the step with the mounting piece, so it can absorb the thickness of the lower frame decorative frame, and the conventional plate In addition, since the wiring device plate including the lower frame, the plate frame, and the decorative cover is attached to the wiring device, the wiring device has a dignified appearance in appearance.
