DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to FIGS. FIG. 1 is an exploded view showing a wiring device according to the present invention. FIG. 2 is a state diagram showing a state in which the wiring device according to the present invention is mounted on a mounting surface, where (a) shows a front view, (b) shows a side view,
(C) shows a rear view. 3A and 3B show a fireproof cover, FIG. 3A shows a front view, FIG. 3B shows a side view, and FIG. 3C shows a top view. FIG. 4 is an explanatory view showing a method of attaching the fireproof cover to the plate frame.

In the wiring device of the present embodiment, the wiring device of the non-fireproof structure can be easily changed to the fireproof structure by attaching a fireproof cover to the back surface of the wiring device of the nonfireproof structure. . At that time, it is possible to cover most of the back surface of the wiring device using the fireproof cover, so that it is possible to provide a wiring device excellent in fire resistance.

As shown in FIG. 1, a wiring device according to the present embodiment has a plate frame 1 attached to an embedding hole formed in a wall or the like, and a plate frame formed so as to close an outer peripheral portion of the plate frame 1. 1 and a decorative plate 3 attached to the base 1.

Here, the wiring module 4 is detachably attached to a rectangular opening formed in the center of the plate frame 1. The opening only needs to be such that one wiring module can be attached. Further, a panel cover 5 is provided in the opening 30 of the frame-shaped decorative plate 3 so as to close a gap between the decorative plate 3 and the wiring module 4. In addition, for example, it is turned on /
In the case of a wiring module 4 such as a piano handle switch that is turned off, a handle (not shown) is used instead of the panel cover 5.

A fire-resistant cover 6 made of a fire-resistant material such as a hot-dip galvanized steel plate is claw-fitted to the back surface of the plate frame 1. As shown in FIG. 3, the fireproof cover 6 has an insertion hole 6b in the center of the bottom surface into which the connection line L connected to the wiring module 4 is inserted. Claw receiving portion 16a and claw receiving hole 16b to be formed
There are a total of four engaging claws 6c, two on each side end, which are elastically fitted to each other. The fireproof cover 6 has screw engaging portions 6d having a concave shape on both side ends, and is engaged and fixed to the plate frame 1 not only by claw fitting but also by mounting screws 12a.

The plate frame 1 is provided with a disc-shaped frame main body 1a slightly larger than an embedding hole formed in a mounting surface such as a wall surface, and the above-mentioned rectangular opening is formed in the center. At the opposite peripheral portions corresponding to the respective central portions of the four sides of the opening, screw holes 12 used for screwing when the mounting surface is sandwiched between the clamp and the plate frame are formed, and the structure of the mounting surface is formed. There are provided two holding portions 13 used for fixing the plate frame 1 to the mounting surface by holding the material between the scissors 7 arranged on the back surface.

Here, the pair of screw holes 12 is for fixing the plate frame 1 to the mounting surface using, for example, a wood screw or the like, and the mounting screws 12a are provided in the scissors fitting 7 through the screw holes 12. Screw hole 7b. Clamping part 1
Numeral 3 is provided so as to extend from the lower surface of the plate frame 1 and along a concave portion 6a of the fireproof cover 6 described later.
And guides the handle 7a suspended from the scissors 7 to facilitate the penetration into the handle hole 17 provided in the plate frame 1. Handle 7
With a, it is possible to reduce the problem that the scissors 7 drop to the back surface of the mounting surface.

The holding portion 13 has a U-shaped cross section that opens outward, and guides a handle 7a that is suspended from the scissors 7 using the U-shaped interior.
7 is bent after being inserted, and the plate frame 1 is temporarily fixed to the mounting surface. That is, since the plate frame 1 can be fixed to the mounting surface by the mounting screws 12a while being temporarily fixed by the handle 7a, the mounting screws 12a can be easily screwed. The handle 7a used for temporary fixing is cut off at an appropriate position because the handle 7a becomes unnecessary if it is fixed by the mounting screw 12a.

The plate frame 1 is formed with a fitting hole 19 for fitting and mounting the decorative plate 3. The plate frame 1 is provided with a fitting concave portion and a fitting hole for mounting a panel cover 5 that closes a gap between the decorative plates 3 other than the upper surface portion where the operation portion of the wiring module 4 is formed.

Next, a description will be given of a wiring module 4 embedded in a mounting surface such as a wall surface using the wiring device of the present embodiment. The wiring module 4 attached using the wiring device is formed into a standardized size module. The wiring module 4 is provided with a locking projection (not shown), and the wiring module 4 is fitted by fitting the locking projection to a locking claw (not shown) provided on the plate frame 1.
Are fixed to the plate frame 1.

In the wiring apparatus according to the present embodiment, the wiring module 4 is mounted on the plate frame 1, the connection line L is inserted into the insertion hole 6 b of the fireproof cover 6, and then the connection line L is mounted on the wiring module 4. , Fireproof cover 6 to plate frame 1
The wiring device can be made to have a fire-resistant structure simply by fitting it with a claw.

[0018]

As described above, according to the first aspect of the present invention, the plate frame attached to the embedding hole formed in the attachment surface such as the wall surface and the outer peripheral portion of the plate frame are closed. And a panel cover attached to the decorative plate by exposing an upper surface portion of one wiring module attached to an opening formed in the plate frame and being mounted in the decorative plate. Since a fire-resistant cover engaged and fixed so as to cover a portion embedded in the mounting surface from the back surface of the plate frame is provided, it is not necessary to bury the fire-resistant cover in the mounting surface in advance, which is simple. In addition, it is possible to provide a wiring device capable of changing a wiring device having a non-fireproof structure to a fireproof structure.
