In order to achieve the above object, the wiring device mounting apparatus of the present invention according to claim 1 is a makeup in which an opening of the wiring device is provided in a mounting plate of the wiring device such as an outlet block. In a wiring device mounting device in which a plate is locked, a locking edge portion is projectingly provided on the mounting plate, a rounded portion is provided at the tip of the locking edge portion, and a locking plate projectingly mounted on the mounting plate is provided on the decorative plate. It is characterized in that a locking projection that can be locked at the edge is provided in a protruding manner.

According to a second aspect of the present invention, there is provided a wiring device mounting apparatus according to the first aspect, wherein the mounting plate is made of metal, the decorative plate is made of synthetic resin, and the mounting plate is made of synthetic resin. The roundness of the tip of the locking edge is characterized in that the tip of the locking edge is formed by bending into a cylindrical shape.

In the present invention, the wiring device includes a switch and the like in addition to the outlet block.

Further, in the present invention, it is preferable to use a material such as a coated steel plate, aluminum or the like as the wiring device mounting plate in terms of strength, cost and the like. Further, in the present invention, the decorative plate is preferably made of synthetic resin such as ABS resin and ACS resin in terms of cosmetic properties and light weight.

[0009]

In the wiring device mounting apparatus of the present invention, the mounting plate is provided with a rounded locking edge, and the decorative plate is locked by the locking edge projected on the mounting plate. Since the stop projection is provided, the decorative plate can be attached to the mounting plate by locking the locking protrusion of the decorative plate with the locking edge of the mounting plate, and the locking edge of the mounting plate is rounded. Since it is provided, even if the decorative plate is repeatedly attached and detached, the locking protrusions are not easily worn away.

Embodiments of the present invention will now be described with reference to the drawings. 1 is an exploded perspective view showing an example of the wiring device mounting apparatus of the present invention, FIG. 2 is a cross-sectional view of the wiring device mounting apparatus of the present invention shown in FIG. 1, and FIG. 3 is a perspective view seen from the rear side of an outlet block.

In FIG. 1, reference numeral 1 denotes a gypsum board wall to which a wiring device such as an outlet block is to be attached, and a vertically elongated rectangular opening 11 is formed at a place where the outlet block is mounted.

Reference numeral 2 is a mounting plate made of painted steel plate, and the mounting plate 2 has a size enough to cover the opening 11 of the wall 1 to be mounted. -Shaped electric wire insertion hole 23 is provided in three steps, a mounting hole 24 is formed in the upper and lower central portions thereof, locking edges 25 are projected on both sides thereof, and the tip of the locking edge 25 has a cylindrical shape. It is bent and rounded.

An outlet block 3 is provided with an outlet insertion hole 31 on the front surface thereof, and hooks 32 projecting upward and to the left and right of the rear surface thereof, and one end of the electric wire 4 is connected from the substantially central portion of the rear surface. ing.

Reference numeral 4 is a substantially C-shaped sandwiching metal fitting, which has a female screw hole 41 at its tip.

6 is a decorative plate made of ABS resin,
Through holes 61, 61, 61 are formed on the front surface at a position corresponding to the outlet block 3, and the mounting plate 2 is formed on the rear surface.
Rib-shaped locking projections 62, 62 that engage with the locking edge 25 are provided so as to project, and heads having a circular cross section are provided at the tips of the locking projections 62, 62. The locking projections 62 may be provided in spots like mushroom-shaped projections 62a as shown in FIG.

To assemble the wiring device mounting apparatus of the present invention, hook the hook 32 of the outlet block 3 from the front of the mounting plate 2 into the wiring device mounting hole 22 of the mounting plate 2, and attach the electric wire 33 of the outlet block 3 to the mounting plate. 2 is inserted into the wire insertion hole 23.

The mounting plate 2 has wiring device mounting holes 2
2. Since the elliptical electric wire insertion hole 23 is provided in three steps, three outlet blocks 3 can be attached.

In this way, the rear surface of the mounting plate 2 with the outlet block 3 mounted on the front surface is brought into contact with the front surface of the peripheral edge portion of the opening 11 of the mounting wall 1, and the mounting plate 2 opens the opening 11 of the mounting wall 1. Block.

The clamp metal fitting 4 is applied to the rear surface of the wall 1 to be mounted, the screw 5 is inserted into the mounting hole 23 at the upper and lower center of the mounting plate 2, and the tip of the screw 5 is screwed into the female screw hole 41 of the clamp metal fitting 4. The mounting plate 2 is mounted on the front surface of the wall 1 to be mounted.

Decorative plate 6 from the front of mounting plate 2
As shown in FIG. 2, the locking projections 62 of the decorative plate 6 are engaged with the locking edges 25 on both sides of the decorative plate 6 to mount the decorative plate 6 in front of the mounting plate 2. When the outlet block 3 is replaced, the decorative plate 6 can be easily detached from the locking edge 25 of the mounting plate 2 by pulling out the decorative plate 6 forward.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific structure is not limited to this embodiment, and there are design changes and the like within the scope not departing from the gist of the present invention. Also included in the present invention. For example, in the illustrated embodiment, wiring devices such as triple outlet blocks are attached vertically, but only one wiring device such as one outlet block is attached or two wiring devices are attached horizontally.
For example, a wiring device such as an outlet block having more than one station can be attached. Further, as the mounting plate, not only a rectangular plate but also a circular plate, an elliptical plate or the like can be used. or,
The means for mounting the mounting plate on the wall to be mounted may be mounted not only by using the sandwiching metal but also by bolts and nuts.

[0022]

In the wiring device mounting device of the present invention, the mounting plate is provided with the locking edge portion, the tip of the locking edge portion is rounded, and the decorative plate is projected on the mounting plate. Since the locking projections that can be locked to the locking edge are projected, the decorative plate can be attached to the mounting plate by locking the locking projections of the decorative plate to the locking edges of the mounting plate. Since the locking edge portion of the plate is rounded, the locking protrusion is not easily worn even when the decorative plate is repeatedly attached and detached.
