DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring device mounting frame.

[0002]

2. Description of the Related Art FIG. 6 shows a conventional mounting frame 1 '. The mounting frame 1' is made of synthetic resin and is mounted on a construction surface such as a wall surface. Ridged ears 2 and 3 are formed on both upper and lower sides of the mounting frame 1 ′, respectively, and the right ear 2 in the drawing includes a wide projection 4 and a narrow recess 5. , Left ear 3
Is composed of a wide recess 7 in which the projection 4 fits and a narrow projection 6 in the recess 5. Therefore, when the mounting frames 1 'are arranged adjacent to each other, the projections 4, 6 of the ears 2, 3 and the recesses 5, 7 are fitted and positioned.

[0003]

However, in the conventional example, since the projections 4 and 6 project in the horizontal direction, they can be positioned in the vertical direction, but they are easily shifted in the horizontal direction. There was a problem that positioning was difficult. The present invention has been made in view of the above points, and has as its object to provide a wiring device mounting frame that allows easy and reliable positioning of up and down, left and right when connecting the mounting frames. It is what it was.

According to a first aspect of the present invention, there is provided a frame body for holding the wiring device with a part of the wiring device inserted into an opening, and for mounting the frame body on a wall surface. Play with the pair of long holes through which the screws are inserted
Up the hole for attaching the frame and the locking piece protruding from the wiring device.
A flexible outer piece locked between the side pieces of the frame body;
A bridging piece for connecting the side pieces to the side pieces; an L-shaped first protrusion protruding from both ends of one side edge of the frame body and bending in opposite directions to each other; L are projected from both ends of the other side edge of the other frame body, and the distal ends thereof are bent in opposite directions so as to mesh with the first projections of another frame body arranged adjacent to the frame body. A second projection of the mold is provided on the frame body.

According to the above construction, the first projections are respectively provided at both ends of one side edge of the frame main body in the vertical direction, and both the first projections are formed so that the tips thereof are in the vertical direction of the frame main body. It is formed in an L-shape that is bent in opposite directions to each other, and second projections are provided at both ends of the other side edge in the vertical direction of the frame body, respectively, and provided on another frame body arranged adjacently. The two second protrusions are formed in an L-shape so as to mesh with the first protrusions, respectively. Therefore, when the two frame bodies are connected to each other, the first protrusion and the second protrusion are connected to each other. As a result, not only the vertical movement of the frame main body is prohibited, but also the horizontal movement (longitudinal direction of the long hole) of the frame main body is prohibited. That is, the positioning of the frame body in the vertical and horizontal directions is facilitated. In addition, the frame body

Embodiments of the present invention will be described below with reference to the drawings. 2 to 5, the frame body 1 is made of a synthetic resin, and an opening 10 for disposing a wiring device is formed in the center. At the top and bottom of the frame body 1, a long hole 11 for screw insertion for mounting to a switch box provided in the wall, a pair of screw holes 12 for screw insertion for directly mounting to the wall, and a plate frame mounting , And an L-shaped insertion hole 14 for inserting and locking the locking portion of the scissors for holding the frame body 1 with the construction material interposed therebetween.

The size of the frame main body 1 is such that three wiring devices each having a size equivalent to one standardized wiring device module can be mounted. The structure in which the outlet, the switch 15, and the like, which are wiring devices, are detachably mounted is formed as follows. That is, on one side piece 18 of the frame main body 1, three pairs of locking holes 19 penetrating on both sides are formed. A pair of locking pieces 17 protruding from a metal assembly frame 16 of the switch 15 are inserted and locked into the pair of locking holes 19.

On the outside of the other side piece 20 of the frame main body 1, a flexible outer piece 22 is integrally formed via two bridging pieces 21 on both sides and a middle piece. A flexible and convex locking projection 23 is formed on the outer piece 22 between the bridging pieces 21, and the other locking piece 17 of the switch 1 is locked on both sides of the central piece 24. A locking step 25 is formed. Switch 15
In order to attach the lock piece 17 to the frame body 1, one of the locking pieces 17 of the switch 15 is inserted and locked into the locking hole 19 of the side piece 18 of the frame body 1, and the other locking piece 17 is locked by the locking projection 23. The switch 15 is mounted on the frame main body 1 at a position where the switch 15 is pressed against the front side while bending outward and the locking piece 17 is locked over the locking step 25. When the switch 15 is detached from the frame main body 1, the tip of the screwdriver is inserted between the side piece 20 and the locking projection 23 and twisted, so that the locking projection 23 is removed.
Is bent outward to release the locking piece 17 from the locking with the locking step 25.

Next, the gist of the present invention will be described. As shown in FIG. 2, FIG. 4 (a), and FIG. 5 (a), ear portions 30, 31 are integrally formed at both upper and lower ends of both side edges of the frame main body 1, respectively. The ear portion 30 provided on one side edge of the frame main body 1 includes an L-shaped projection 32 that is partially protruded from the side edge of the frame main body 1 and whose distal ends are bent away from each other. Further, the other ear portion 31 includes an L-shaped protrusion 33 whose front ends are bent toward each other so as to have a shape that meshes with the protrusion 32 provided on the other frame main body 1 disposed adjacently. . That is, as shown in FIG. 1, when the two frame bodies 1 are connected, the projections 32, 33 of the both ears 30, 31 are engaged with each other, so that the frame body 1 is positioned vertically and horizontally.
