Description

[Detailed explanation of the idea] [Technical field] The present invention provides a mounting frame for a wiring device.

[Background Art] As shown in FIG. 11, a conventional mounting frame for a wiring device is formed of a dimensional module to which a plurality of wiring devices can be attached.
If one of the wiring devices 2a is a power outlet and the other 2b is a telephone outlet, the wiring contractor will be different. Therefore, when connecting the wiring device 2a and the cable 3a when the connection between the wiring device 2b and the cable 3b previously routed inside the wall 6 has already been completed, the mounting frame 1 is attached to the switch box 4. Remove the fixing screw 5, temporarily separate the mounting frame 1 from the switchbox 4, and at the same time pull out the cable 3b, which has already been connected and is stored in the switchbox 4, and in this state connect the cable 3a to the wiring device 2a. Connect. and then cable 3a
and 3b are housed in the switchbox 4, and the mounting frame 1 is fixed to the switchbox 4 with fixing screws 5.

The cable 3b of the wiring device 2b, which has been previously constructed by the above work, is temporarily placed in the switch box 4.
Even though it is stored in the cable 3b, the person carrying out the subsequent work will have to pull it out again to carry out the work he is responsible for, and if the excess length of the cable 3b is short, it may be difficult to perform the connection work, or cable 3
This requires both a and 3b to be housed in the switch box 4, which poses the problem of making construction extremely difficult.

[Purpose of the invention] The present invention was created in view of the above-mentioned problems, and its purpose is that when multiple wiring devices with different functions are installed, each wiring device can be independently connected to other wiring devices. To provide a mounting frame for wiring equipment that allows construction work to be carried out without affecting the equipment at all.

[Disclosure of the Invention] The present invention includes an opening window for attaching a ready-made one-module wiring device, and a sub-mounting frame at the other end formed by drilling at least a mounting hole and a plate fixing screw hole in the frame side of one end. A concave-convex joint is provided on the frame side to removably connect another mounting hole to the other end of another sub-mounting frame, and when connecting both sub-mounting frames, the dimension between the mounting holes at both ends is adjusted to the mounting pitch of the switch box. They are characterized in that they have corresponding dimensions, and the dimensions between the plate fixing screw holes serve as the mounting pitch for the plate.

The present invention will be explained below with reference to examples.

Example 1 Figure 1 shows this example, in which the sub-mounting frame 1
a and 1b are made of metal plate material and have the same shape, and each sub-mounting frame 1a and 1b has an opening window 7 bored in the center into which the central protrusion of a ready-made one-module wiring device is fitted. However, the center protrusion 11 of the wiring devices 2a, 2b is attached to the opening edges on both sides of the opening window 7.
Protrusions 8a and 8b are provided to engage with engagement recesses 12 provided on both sides of the base of the holder. One protrusion 8
A hole 9 for inserting a jig is provided on the back of a, and by deforming the connecting piece 10 connected to the sub-mounting frames 1a and 1b toward the opening window 7 side with the jig, the protrusion 8a can be inserted into the opening window. The wiring devices 2a, 2b are fixed to the sub-mounting frames 1a, 1b by protruding in seven directions and engaging with the engagement recesses 12 of one of the wiring devices 2a, 2b. At this time, the other protrusion 8b is connected to the other engagement recess 12 of the wiring devices 2a, 2b.
is engaged with.

Now, mounting holes 13a, 13b are bored in both upper and lower end frame sides of each sub-mounting frame 1a, 1b, and a plate fixing screw hole 16 corresponding to the mounting hole 15 of the plate 14 is bored in one frame side, and the plate fixing screw hole 16 corresponding to the mounting hole 15 of the plate 14 is bored in the other frame A substantially circular projection 17 is formed on one side of the outer edge of the frame, and a notch hole 18 having the same shape as the projection 17 is formed on the other side.

Then, the protrusion 17 on one side 1a is fitted into the notch hole 18 on the other side 1b, and the protrusion 17 on the other side 1b is fitted into the notch hole 18 on one side 1a. Both sub-mounting frames 1
When a and 1b are connected, the dimension between the upper and lower plate fixing screw holes 16 corresponds to the mounting pitch of the mounting holes 15 of the ready-made plate 14, which corresponds to the mounting frame of the normal 3-module size. .
Note that 29 in the figure is a scissor fitting engagement hole.

Next, construction using this example will be explained.
First, when installing the wiring devices 2a, 2b using the switchbox 4 shown in FIG. 1, a switchbox cover 19 is placed over the opening of the switchbox 4 in this embodiment. This attachment is carried out by fastening a fixing screw (not shown) inserted into the screw hole 20 on the switchbox 4 side through the mounting hole 21 of the switchbox cover 19. The switch box cover 19 has its central portion protruding forward, and the extent of the protrusion ensures a margin for painting the wall material, and is also referred to as a coating margin cover. Then, openings 22a, 22b corresponding to the wiring devices 2a, 2b are bored in the upper and lower parts of this protrusion, and each opening 22a,
A fixing screw hole 2 is provided in the center of the upper and lower opening edges of 22b, respectively.
A projecting piece 31 with holes 3a and 23b protrudes, and the dimension between each fixed screw hole 23a and 23b exactly corresponds to the dimension between the upper and lower mounting holes 13a and 13b provided in each sub-mounting frame 1a and 1b. are doing.

Here, a cable (not shown) that has been pre-wired in the wall is introduced into the switch box 4 through the knockout hole 26 of the switch box 4,
Further, the cables are led out through the openings 22a and 22b of the switch box cover 19. Next, the wiring devices 2a, 2b are attached to each of the sub-mounting frames 1a, 1b, and the sub-mounting frames 1a, 1b are inserted into the fixing screw holes 23a, 23b provided corresponding to the openings 22a, 22b of the switch box cover 19. The sub-mounting frames 1a, 1b are fixed to the switchbox cover 19 by screwing fixing screws (not shown) inserted through the mounting holes 13a, 13b.
At this time, the sub-mounting frames 1a and 1b are connected by the above-mentioned concave-convex joint.

Next, when connecting the wiring devices 2a, 2b and the pre-wired cables, when one 2a is a power outlet and the other 2b is a telephone outlet, the cable is connected to the wiring devices 2a, 2b. Since each contractor is different, for example, an electrician will remove only the sub-mounting frame 1a to which the wiring device 2a, which is a power outlet, is attached, connect the corresponding cable to the wiring device 2a, and attach the sub-mounting frame to the switch box cover 19. Fix 1a.

Further, a telephone worker who connects a wire to a wiring device 2b such as a telephone outlet removes only the sub-mounting frame 1b to which the wiring device 2b is attached, and connects the corresponding cable to the wiring device 2b. After this connection, the sub-mounting frame 1b is fixed to the switchbox cover 19 again.

FIG. 3 shows a case of so-called boxless construction in which the switch box 4 is not used. The screw hole 30 of the scissor fitting 31 is engaged with the L-shaped engagement hole 29 drilled in the mounting frames 1a, 1b, and the fixing screw 5 inserted through the mounting hole 13a, 13b of each sub-mounting frame 1a, 1b is inserted. By fastening the sub-mounting frames 1a, 1b to the scissors 28, the wall panel 6' is held between the sub-mounting frames 1a, 1b and the scissors 28, and the sub-mounting frames 1a, 1b are fixed.

Embodiment 2 In this embodiment, each sub-mounting frame 1 is
In this case, the openings 22a and 22b of the switchbox cover 19 shown in FIG. 1 are connected vertically to form one opening 22. A screw hole 2 corresponding to the mounting hole 13b is provided at the center side edge of 22.
A projecting piece 31 having a hole 3b is provided in a protruding manner. Therefore, in this embodiment, the boundary between the openings 22a and 22b of the switchbox cover 19 in FIG. 1 is unnecessary. In this embodiment, the engagement hole 29 for the scissors, which was provided in the sub-mounting frames 1a and 1b of the first embodiment, is not provided.

Embodiment 3 In this embodiment, the concave-convex joint for connecting the sub-mounting frames 1a and 1b is formed by a rectangular protrusion 17' and a concave notch 18' having the same shape as the protrusion 17', as shown in FIG. A mounting hole 13b is bored in the protrusion 17', and a protrusion 31 is provided at the center of both opening edges of the switch box cover 19 to correspond to the mounting hole 13b, and is vertically shifted relative to the center line. are projected, and a screw hole 13b is bored in each of the projecting pieces 31.

[Effects of the invention] The invention provides an opening window for attaching a ready-made one-module wiring device, and a sub-mounting frame at the other end, which is formed by drilling at least a mounting hole and a plate fixing screw hole in the frame side of one end. Since there is a concave-convex joint on the frame side that removably connects another mounting hole to the other end of another sub-mounting frame, it goes without saying that one sub-mounting frame can be used as an independent mounting frame. It can be used as a mounting frame to attach multiple wiring devices by connecting two sub-mounting frames, and when connecting both sub-mounting frames, the dimension between the mounting holes at both ends corresponds to the mounting pitch of the switch box. year,
Moreover, since the dimension between the plate fixing screw holes is used as the mounting pitch of the plate, it is of course possible to attach it to a ready-made switchbox, and also to use a ready-made plate, and each sub-mounting frame can be connected to each other in a detachable manner. Therefore, when connecting cables that have been pre-wired to wiring devices attached to each sub-mounting frame, each sub-mounting frame can be removed separately and the cables can be connected. Therefore, each wiring device requires a different wiring contractor. However, it is possible to pay attention only to the cable of the corresponding wiring device, and there is no trouble associated with the work of pulling out the cable that has been connected from the switch box and storing it again.
