Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a wiring component mounting device used when, for example, wiring devices such as electrical outlets and light switches are mounted in a flat state on a wall or floorboard.

[Prior art and its drawbacks]

Conventionally, wiring devices such as electrical outlets and switches have been attached to a wall A in a flat manner as shown in FIG. That is, the locking fitting 13 is movably attached to the mounting piece 12 of the unit plate 11 of the wiring device, and the screw 14 is screwed between the locking fitting 13 and the above-mentioned mounting piece 12 to close the wall A. The unit plate 11 was fixed in a sandwiched manner.

However, in this structure in which the screw 14 is screwed between the unit plate mounting piece 12 and the locking fitting 13 to sandwich the wall A, the length of the screw 14 is limited, and If the opening angle between the mounting piece 12 and the metal fitting 13 becomes large, it becomes difficult to screw the screw 14 in, so there is a drawback that it cannot be applied to the wall A having a large plate thickness.

[Purpose of invention]

This idea was created in view of the problems mentioned above. For example, even if the wall dimensions are very thick,
It is an object of the present invention to provide a wiring component mounting device that enables reliable and simple mounting.

[Key points of the idea]

In other words, the wiring component mounting device according to this invention is
Passing a screw through a screw insertion hole formed in a mounting piece of the unit plate, and sandwiching a clamping metal fitting having support points on both sides of the unit plate between the metal fitting screwed onto the screw and the mounting piece, The space between the clamping metal fitting and the mounting piece is opened and closed about the support point in accordance with the vertical movement of the abutting metal fitting as the screw rotates.

[Example of idea]

An embodiment of this invention will be described below with reference to the drawings.

FIG. 1 shows the assembled structure of this wiring component mounting device, which is equipped with a unit plate 11 to which wiring devices can be mounted as required. A mounting piece 12 is integrally provided at the end of this unit plate 11, and a screw insertion hole 21 is formed in this mounting piece 12. Further, support pieces 22a and 22b are provided on both sides of the unit plate 11 at right angles downwardly to the plate surface, and support holes 23 are provided in the support pieces 22a and 22b.
a, 23b are formed. Next, at the lower part of the mounting piece 12, there is provided a clip 24 whose main body is sandwiched between the support pieces 12 on both sides and whose one end engages with the support holes 23a and 23b. One end of this clip 24 is provided with support holes 23a and 23b of the unit plate 11.
Protrusions 25a and 25b that can be engaged with are provided, and a corrugated biting protrusion 26 facing the direction of the mounting piece 12 is formed on the other end side. A long hole 27 is formed in the flat plate surface between this biting projection 26 and the projections 25a and 25b, and tongue pieces 28a and 28b are provided on both sides of the flat plate at right angles downward to form an engaging hole 29a. , 29b. Furthermore, the engagement hole 29 is located at the bottom of the clip 24.
A stopper fitting 30 that engages with a and 29b is provided. A tipping prevention piece 31 is formed at the end of this fitting 30, and an engaging hole 2 for the clipping fitting 24 is formed at both ends.
A key-shaped engagement piece 32 that can be engaged with 9a and 29b
a, 32b are provided, and rotation prevention pieces 33a, 3 are provided.
3b is formed. A screw hole 3 is provided in the center of this fitting 30 to be screwed into a screw 34 inserted through the screw insertion hole 21 of the unit plate mounting piece 12.
form 5. In this case, the engagement holes 32a and 32b provided on both sides of the stopper fitting 30 are inserted into the clamping fitting 24.
When engaged with the engagement holes 29a, 29b, the rotation prevention pieces 33a, 33b on both sides of the metal fitting 30 are sandwiched between the tongue pieces 28a, 28b of the clamping metal fitting 24, respectively.

Now, as shown in FIGS. 2A to 2D, the stopper fitting 30 is assembled into the clamping fitting 24. That is,
Rotate the anti-fall piece 31 of the stopper 30 along the lower surface of the clip 24 as shown by arrows a and b, and fit the engaging pieces 32a and 32 of the clip 30 into the engagement holes 29a and 29b of the clip 24, respectively. 32b is engaged. Then, the protrusions 25a and 25b of the clip 24 in which the stopper 30 is installed are inserted into the support hole 2 of the unit plate 11 in an open state in which both sides of the clip 24 are not sandwiched between the support pieces 22a and 22b.
3a, 23b, and then rotate the clip 24 around the protrusion engaging portion so that both sides thereof are sandwiched between the support pieces 22a, 22b.
is screwed from the screw insertion hole 21 of the unit plate mounting piece 12 to the screw hole 35 of the stopper fitting 30 via the elongated hole 27 of the clip fitting 24. FIG. 3 shows how the metal fittings 24, 30 are assembled into the unit plate 11, viewed from the bottom side of the unit plate 11. In this case, when the screw 34 is screwed into the abutting metal fitting 30, even if the screw 34 is in the maximum open state, both sides of the clamping metal fitting 24 are sandwiched between the unit plate support pieces 22a and 22b. Also, the metal fitting 3
Since both sides of the clip 24 are sandwiched between the tongue pieces 28a and 28b of the clip 24, the protrusions 25a and 25b of the clip 24 do not fall out of their support holes 23a and 23b, and the stopper 30 The engaging pieces 32a and 32b are connected to the engaging hole 2 of the clip 24.
It will never fall off from 9a and 29b.

In other words, in order to mount the mounting device constructed in this manner on, for example, a thick wall A, first loosen the screws 34 as far as they will go so that the distance between the unit plate mounting piece 12 and the biting protrusion 26 of the clip 24 is equal to that of the unit. The support holes 23a and 23b of the plate 11 are moved in an arc with the support holes 23a and 23b serving as fulcrums to keep the plate 11 wide open. and,
As shown in FIG. 4, the wall body A is inserted between the widely opened unit plate mounting piece 12 and the biting protrusion 26, and the screw 34 is tightened and sandwiched therebetween. As a result, the clip 24 is attached to the support hole 2 of the unit plate 11.
3a, 23b as fulcrums, it moves in an arc in the direction shown by arrow c, and the biting protrusion 26 moves against the wall A.
It is in a state where it strongly bites into the back side of. Therefore, the wiring unit can be easily and reliably attached even to the thick wall A.

In this case, the screw 34 is inserted into the elongated hole 27 of the clip 24.
Since it is screwed onto the stopper fitting 30 through Since the screws 34 do not fall off from the unit plate mounting piece 12, tightening the screws 34 is extremely easy.

[Effect of idea]

As described above, according to this invention, the space between the clip and the mounting piece is opened and closed in response to the vertical movement of the stopper as the screw inserted into the unit plate mounting piece rotates. For example, even if the thickness of the wall changes, the wall plate can be easily sandwiched, and the wiring unit can be installed reliably and easily.
