Then, the cover 1 is fitted to the body 2 and the legs of the U-shaped assembly frame 11 are fitted into the grooves 54 and 55 from the cover 1 side, and the forked portion 57 at the tip of the leg is fitted.
Are deformed and spread to lock, whereby both ends of the body 2 and the cover 1 are joined by the assembling frame 11. Also, the rivet 12 is inserted from the hole 52,
By inserting the body 2 and the cover 1 by caulking and fixing them, the substantially central portion in the longitudinal direction of the body 2 and the cover 1 is connected with the caulking studs 12. In this manner, the cover 1 is connected to the body 2 to assemble and form a double outlet in which two sets of plug insertion portions 4 are provided side by side in the case 3.

The outlet mounting frame 8 is formed by arranging two mounting openings 9 in the longitudinal direction, and the two mounting openings 9 are provided at both ends in the direction in which the two mounting openings 9 are arranged. The part is provided with a locked part 10. The middle frame 13 between the two mounting openings 9 is provided with a substantially E-shaped jig insertion opening 14 at a position corresponding to one of the locked parts 10. A substantially E-shaped jig insertion opening 14a is formed in the portion of the outlet mounting frame 8 corresponding to the locked portion 10 at the end of the opening 9 opposite to the middle frame 13 of the mounting opening 9. Is provided. Here, the edges of the jig insertion openings 14 and 14a on the side of the locked portion 10 are shown in FIG.
As shown in FIG. 4 (a), it is deformed so as to be recessed toward the jig insertion openings 14, 14a.

In order to incorporate a double outlet into the outlet mounting frame 8 as described above, the projections 50 on both sides of the cover 1 of the case 3 are respectively fitted to the two mounting openings 9 of the outlet mounting frame 8. The locking portion 7 is locked to the locked portion 10 while being fitted. in this case,
As shown in FIG. 14A, of the locked portions 10 provided on both sides of the two mounting openings 9, the portions which do not correspond to the substantially E-shaped jig insertion openings 14 and 14 a are formed. The locking portion 7 is fitted into the locking portion 10, and then the jig 60 is inserted into the jig insertion openings 14 and 14 a and the jig 60 is operated to deform the edges of the jig insertion openings 14 and 14 a. Let the jig insertion port 14, 14
Each of the locked portions 10 corresponding to a is locked to the locking portion 7. Here, when the jig 60 is inserted into the jig insertion slot 14, the bottom of the concave portion 1 a of the cover 1 portion of the case 3 is located behind the middle frame 13, but behind the jig insertion slot 14. Since the escape recess 15 exists, when the jig 60 is inserted into the jig insertion port 14 as shown in FIG.
14 can be released by inserting the leading end portion of the jig 60 into the escape recess 15. Therefore, after the jig 60 is inserted in the direction of the arrow A in FIG. 14B, the jig as shown in FIG. When the work 60 is moved in the direction of arrow B for caulking and fixing work, the jig 60 should be sufficiently hooked to the edge of the jig insertion port 14 even if the outlet mounting frame 8 is, for example, about 1.2 mm thick. It will be possible to hold and press it, and as a result,
The locking of the locked portion 10 and the locking portion 7 by the operation of the jig 60 can be performed using a machine, and automation can be performed.
By the way, when there is no escape recess 15 as shown in FIG. 15B, the jig 60 cannot be pressed against the edge of the jig insertion opening 14 with a sufficient margin, and Jig 6
0 may deviate, and automation is not possible. Also, since the case 3 does not exist on the back of the jig insertion opening 14a, the jig 60 can be sufficiently inserted into the jig insertion opening 14a to obtain a sufficient hooking margin. There is no problem in automating the process.

The double outlet is mounted on the outlet mounting frame 8 as described above.
The case 3 is placed in a concave portion of a wall of a building, and the outlet mounting frame 8 is mounted near the opening. In the present invention of the above embodiment, two sets of plug insertion portions 4 are provided in the case 3 side by side, and a blade receiving portion 5 provided in the plug insertion portion 4 and a blade provided in the adjacent plug insertion portion 4 are provided. Since two corresponding receiving parts 5 are electrically connected to each other, and two pairs of electrically connected blade receiving parts 5 are connected to the external wiring, two connecting parts 6 are provided. One connecting part 6 can be connected to the power supply side, and the sending wiring can be connected to the other one connecting part 6. For this reason, the feed wiring can be performed without the joint box when the feed wiring is performed in the double outlet.

By the way, according to the present invention, even if the plug is plugged into or out of the double outlet as described above, or if the plug is unplugged improperly, the cover 1 and the body 2 are located at the center of the double outlet. Since the cover 1 and the body 2 are joined by the caulking studs 12, there is no gap between the cover 1 and the body 2 in the central portion in the longitudinal direction. Even if the case 3 is warped, no gap is formed between the cover 1 and the body 2 at the central portion in the longitudinal direction.
