Description

[Detailed Description of the Invention] The present invention relates to a wiring device, which includes a case body 8 made of metal and having a U-shaped cross section, and a case cover made of metal and having a U-shaped cross section covered above the case body 8. 7
In the wiring device device in which a case 1 is formed with the case 1 and an end cap 4 is fitted to the end of the case 1, the end of the case cover 7 and the side end in the elongated direction are bent to form a two-layer structure. The folded portion 31 is shaped, and the end cap 4
This relates to a wiring device device characterized in that ribs 33 which are engaged with the step portions of the folded portion 31 of the case cover 7 are projected from both sides of the case cover 7.

The present invention provides a wiring device for preventing an end cap fitted to a case cover from easily coming off.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In the figure, reference numeral 1 denotes a rectangular cylindrical case composed of a metal case cover 7 and a metal case body 8.

The case cover 7 is a long piece with a U-shaped cross section, and both ends of the case cover 7 and both ends in the longitudinal direction are bent by a predetermined width to form an outer layer and a folded inner layer, as shown in FIG. A folded portion 31 consisting of two layers, . They each form 31□.

Reference numeral 32 denotes a stepped portion formed by the thickness of the folded layer of the folded portion 31.

4 is an end cap made of insulating material such as synthetic resin,
This end cap 4 is fitted to an end inside the case 1, and has a knockout portion 13 that is opened at the bottom and is made thinner at a portion near the center of the outer surface to make it easier to tear.

This knockout portion 13 is to be struck with a screwdriver or the like when necessary to allow the broken electric wire to pass through.

Further, both sides of the end cap 4 are narrowed down one step to allow a substantially U-shaped elastic projection 5 to protrude inwardly, and the image tip of this projection 5 has a surface perpendicular to the direction in which the projection 5 projects. A joint box 3, which connects an outlet disposed inside the case 1 and an electric wire for supplying commercial power from the outside, is brought into contact with the collar 6, respectively.

Rectangular parallelepiped ribs 33 protrude from both sides of the protrusion 5 of the end cap 4, respectively.

When the end cap 4 is fitted onto the case cover 7, the rib 33 is engaged with the stepped portion 32 of the folded portion 31.

That is, the outer surface of the rib 33 is locked to the folded portion 311 side, and the lower surface of the rib 33 is locked to the folded portion 312 side.

In addition, a folded part 34 consisting of two layers is formed at both ends of the case body 8, and the folded part 34 can hide the broken surface of the case body 8, so that it will not be damaged even if it is touched. There is no such thing.

FIG. 2 shows a state in which the end cap 4 is fitted onto the case cover 7, and as shown in FIG. 2C, the vertical surfaces of the end cap 4 and the case cover 7 are flush with each other.

By the way, the end cap 4 and case cover 7 are used for a multiple outlet with multiple outlets as shown in Fig. 3, and in Fig. 3, four outlet bodies 15 are used to insert the plug. Four mouths 11 are formed.

Blade holder springs 17, 17 each having one end connected to a pair of cords 12 are placed on an outlet body 15, and an insertion hole 36 is formed thereon through which the tip of the blade holder spring 17 is inserted.
9 and two leaf springs 20, 20 and two doors 21 and 21 are arranged, and the outlet body 15, the middle frame 19, and the door 2 are arranged.
A cover 22 having a head 23 and a plug insertion hole 11 is placed above the plug 1 .

Install these outlets at predetermined positions on the case body 8, and insert the fixing screws 16 from the bottom surface of the case body 8 through the insertion holes 37 of the case body 8 and the through holes 27 on both sides of the outlet body 15, and insert them into the cover 22. Screw it into the hole.

In this way, the outlet consisting of the outlet body 15 and the cover 22 is fixed to the case body 8 with the two fixing screws 16 and 16.

Furthermore, the case cover 7 is provided with an opening window 24 for exposing the plug insertion port 11 of the cover 22 above the outlet.
to cover.

The assembly screw 25 is passed from the upper surface of the case cover 7 through the insertion hole 38 of the case cover 7 and the through hole 39 of the cover 22 and screwed into the tapped hole 40 of the outlet body 15.

In this way, the case cover 7 is fixed to the outlet with the assembly screws 25.

As mentioned above, in the present invention, the ends and longitudinal side edges of the metal case cover are bent to form a folded part consisting of two layers, so that the broken surface of the case cover is not bent inward. There is no risk of injury even if you touch it with your hands.Furthermore, the end cap that is fitted to the case cover has ribs protruding from both sides to be engaged with the stepped part of the folded part of the case cover. The ribs and the stepped part of the folded part of the case cover lock together, so even if the case cover is removed from the case body during installation, the end cap will not fall off, making installation easier.Moreover, no set screws are required, making installation easier. It has the advantage of improving
