Since a plurality of wiring devices 2 can be attached to the middle frame 3, in addition to attaching one wiring device 2, a plurality of types of wiring devices 2 can be attached in combination. For example, in addition to attaching the outlet 2a as the wiring device 2 as shown in FIG. 7A, the outlet 2a and the earth terminal 2c are combined as shown in FIG. 7B, or the outlet 2a as shown in FIG. And a grounded outlet 2b and a ground terminal 2c.

In the places where the wiring device 2 is not attached to the middle frame 3, the same size as that of the wiring device 2
7 (a) by attaching the blank plate 50 by engaging the claw pieces 10 with the claw engagement holes 11a and 11b using the blank plate 50 formed with the “0”.
An opening is not formed in the middle frame 3 as shown in FIG. In order to remove the wiring device 2 attached to the middle frame 3 from the middle frame 3 as described above, the inside of the tongue piece 27 on one side 3b on the longitudinal side of the middle frame 3 needs to be fixed with a tip of a flathead screwdriver or the like. 10b, the tongue 27 is elastically bent slightly in the direction of the arrow in FIG. 10B, and the engagement of the claw 10 of the wiring device 2 into the claw engagement hole 11b can be performed. .

The inner frame 3 to which the wiring device 2 is attached in this manner
Are arranged in the rainproof cover 1 above the engaging flange piece 9 and the decorative frame 4 is arranged in the rainproof cover 1 below the engaging flange piece 9. Rainproof cover 1
Attached to the inner circumference of the opening on the lower surface of the. When attaching the decorative frame 4 to the rainproof cover 1, the decorative frame 4 is inserted into the rainproof cover 1 from an opening on the lower surface and is pushed upward to engage with the engaging pieces 5 provided on each of the engagement pieces 5 at both ends of the decorative frame 4. The inclined surface 8a on the upper surface of the projection 8 hits the lower edge of the engagement flange piece 9 of the rainproof cover 1. However, when the decorative frame 4 is further pushed up, the elastic tongue piece 38 is elastically deformed inward, and the engagement projection 8 Is displaced inward, and when the engagement protrusion 8 is pushed upward from the engagement collar piece 9,
As shown in FIG. 6A, the inclined surface 8 a on the lower surface of the engaging projection 8 is locked on the upper edge of the engaging flange 9, and the flange 7 of the decorative frame 4 contacts the lower surface of the engaging flange 9. Touch In this manner, the engaging flange piece 9 of the rainproof cover 1 is engaged between the engaging protrusion 8 of the decorative frame 4 and the flange piece 7 to attach the decorative frame 4 to the inner periphery of the rainproof cover 1. A decorative frame 4
Can be attached with one touch by an engagement means. Conversely, by strongly pulling the decorative frame 4 downward, it is possible to disengage the engagement by the engaging projection 8 and remove the decorative frame 4 below the rainproof cover 1.

Next, when the middle frame 3 to which the wiring device 2 is attached is put into the rainproof cover 1 through the opening on the back and pushed down, the middle frame 3 is placed between the engagement pieces 5 at both ends of the decorative frame 4. The fitting projections 28 provided on the engagement pieces 6 at both ends of the middle frame 3 are guided by the guide inclined surface 37a of the guide projection 37 at the upper end of each engagement piece 5, and 5 and is fitted in the fitting hole 35 of the engaging piece 5 as shown in FIG. By fitting the fitting projection 28 into the fitting hole 35 in this manner, each engaged piece 6 of the middle frame 3 is engaged with the inside of each engaging piece 5 of the decorative frame 4, and the decorative frame 4 The inner frame 3 can be fixed to the inner frame 3 in this manner, and the inner frame 3 can be attached by one-touch operation by the engaging means. At this time, even if the elastic tongue piece 38 of the decorative frame 4 is slightly deformed inward due to the engagement of the engaging projection 8 with the engaging flange piece 9 of the rainproof cover 1, the elastic piece 30 of the middle frame 3 is not deformed. To easily deform along the inner surface of the elastic tongue 38, the engaging piece 5 of the decorative frame 4
This does not hinder the engagement of the engaged piece 6 of the middle frame 3 between them. In this way, as shown in FIG. 2, the wiring device 2 attached to the middle frame 3 can be mounted in the rainproof cover 1 via the decorative frame 4, and the rainproof type wiring device as shown in FIG. It can be assembled. Further, when the inner frame 3 is engaged with the decorative frame 4 and joined in this manner, the locking projections 32 of the inner frame 3 are locked on the upper surface of the engaging flange pieces 9 of the rainproof cover 1, and the inner frame 3 is locked. 3 is prevented from dropping below the rainproof cover 1.

In this manner, the wiring device 2 is connected to the rainproof cover 1.
After the tip of an electric wire 52 wired inside the wall is inserted and connected to an electric wire insertion hole 51 containing a quick connection terminal of the wiring device 2, the screw 53 is connected to the screw hole 2 of the rainproof cover 1.
By screwing into the screw holes 46 at both ends of the mounting frame 42 through the mounting frame 2, the rainproof cover 1 incorporating the wiring device 2 can be mounted on the wall surface 13.

In the rainproof type wiring device mounted on the wall surface 13 as described above, when a plug or the like is inserted into the wiring device 2 such as an outlet, the cord 14 such as the plug is imaginary line in FIG. As shown by the arrow, the rainproof cover 1 can be hooked on the hooking piece 48 of the cord hooking tool 12 provided at the lower end of the rear inner surface.
When the cord 14 is hooked on the hook piece 48 of the cord hooking device 12 as described above, even if a tensile force acts on the cord 14 as indicated by an arrow, the tension is received by the cord hooking device 12 and inserted into the wiring device 2. It is possible to prevent the plug or the like from directly acting on the plug or the like, and to prevent the plug or the like from being accidentally removed from the wiring device 2.

Although the decorative frame 4 is formed as a separate member from the rainproof cover 1 in the above embodiment, the decorative frame 4 may be formed integrally with the inner periphery of the rainproof cover 1. Good.
