FIG. 2 is a perspective view showing a mounting bracket for an electric device according to an embodiment of the present invention. FIG. 1 is a side view showing a state where the mounting bracket for the electric device is mounted and fixed to the mounting plate 20. It is sectional drawing. As shown in FIGS. 1 and 2, the mounting bracket for an electric device is mounted on and fixed to a mounting plate 20 and clamps and holds the electric device 30, and holds the mounting plate 20 together with the mounting body 2 a. And two scissors fittings 3, 3. FIG. 4 is a front view (a), a bottom view (b), and a side view (c) showing the fitting main body 2a, and FIG. 5 is a front view (a) and a bottom view (b) showing the scissor fitting 3. ) And a side view (c).

The metal fitting body 2a is provided with four hook-shaped locking claws 4 which are hooked and locked in locking grooves (not shown) provided on the back side of the electric device 30 as in the prior art. ing. The metal fitting body 2a is provided with an electric wire insertion port 6 through which an electric wire (not shown) connected to the electric device 30 is inserted. The metal fitting body 2a further includes a screw 11,
Screw holes 9, 9 for inserting 11 are provided.

The scissors fitting 3 is connected to the fitting body 2a. As shown in FIG. 2, the scissors fitting 3 and the fitting body 2a hold the mounting plate 20 from the front and back. Has become. FIG. 3 shows the scissor fitting 3
(A) showing a state in which the metal fitting body 2a is connected to
And a bottom view (b) and a side view (c).

The scissors fitting 3 has connecting claws 3c, 3c for hooking and connecting to the fitting main body 2a. The connecting holes for removably engaging the connecting claws 3c, 3c respectively with the fitting main body 2a. 10 and 10 are provided. However, the connecting holes 10 are provided at four places in the fitting main body 2a to connect the two scissor fittings 3. The scissors metal fitting 3 has its connecting claws 3c, 3c connected to the metal fitting body 2a.
By inserting it into the connection holes 10 and sliding it in one direction, it is engaged and connected to the metal fitting body 2a. Of course, the scissor fitting 3 connected to the fitting main body 2a can be removed from the fitting main body 2 by the reverse procedure.

Further, the scissors fitting 3 includes the screw 11
Is provided with a screw hole 3a. In a state where the scissor fitting 3 is slidably engaged with the fitting main body 2a, the positions of the screw round holes 9 provided in the fitting main body 2a and the screwing holes 3a provided in the scissor fitting 3 overlap. . Further, the scissors 3 have elastic plates 3b, 3b.
b are integrally disposed, and as shown in FIG. 2, in a state where the mounting plate 20 is sandwiched between the scissors fitting 3 and the fitting main body 2a, the fitting is elastically displaced in accordance with the thickness of the mounting plate 20, The mounting plate 20 is elastically pressed.

When the mounting bracket for an electric device having the above structure is mounted and fixed to the mounting plate 20, the mounting plate 20
And a screw insertion hole 20b, 20b corresponding to the screw round hole 9, 9, and the two scissors 3, 3 are connected to the metal fitting body 2a through the cable insertion hole 20a. And the fixture main body 2a and the scissor fittings 3, 3 are connected to the torsion screws 11, 1 through the torsion hole 9, the torsion hole 20b, and the screw hole 3a, respectively.
1 is screwed and fixed to each other. At this time, the edge of the wire insertion opening 20a of the mounting plate 20 is clamped at two places by the fitting main body 2a and the two scissors fittings 3,3.

Further, in the mounting bracket for an electric device of the present embodiment, the screw main bodies 2a are provided with screw holes 11, 8 for inserting the screws 11, 11 therethrough. The elongated holes 8 for the torsion are elongated holes extending in the lateral direction of the metal fitting body 2a. FIG. 6 is a diagram illustrating an example of a usage mode of the electrical device mounting bracket according to the present embodiment, and illustrates a case where the mounting bracket is mounted and fixed to a relatively thick mounting plate 20 such as a wall material. In this case, a female screw groove for screwing the screws 11, 11 can be formed in the mounting plate 20, so that the scissors metal fitting 2 is removed from the metal fitting body 2a, and the screw long hole is formed as in the conventional case. 8, 8 through the screw 11, 11
1, the screw body 2a may be directly screwed and fixed to the mounting plate 20. After that, the electric device 30 may be locked to the metal fitting body 2a. In the present invention, the scissor fitting 3 and the fitting main body 2a may be integrally connected to each other, for example, by connecting them so as to be pivotable with each other. However, as in the present embodiment, the scissor fitting 3 , 3 and the metal fitting body 2 can be detachably attached, as described above, can be screw-fastened not only to the thin mounting plate but also to the relatively thick mounting plate 20. Becomes The metal fitting body 2a is attached to the mounting plate 2 by the screws 11,11.
0, the screw holes 9 and 9
May be substituted for the insertion holes of the screws 11.

FIG. 8 is a view showing a state in which the metal main body 2a is locked to the electric device 30, and shows a use mode of the electric device mounting bracket when a plurality of electric devices 30 are connected. FIG. In FIG. 8, the position of the electric wire insertion port 20a when the metal fitting main body 2a is fixed to the mounting plate 20 is superimposed. In the conventional mounting bracket for an electric device, the screw hole 8 through which the screw 11 is inserted is a round hole. Therefore, when connecting a plurality of electric devices 30 of the same module, a very large wire insertion port 20a is required.
Although it was necessary to provide the mounting plate 20 with the mounting plate 20, it was very troublesome. However, as shown in FIG.
Since the size of “a” can be made smaller than in the case described above, the configuration is very convenient for connecting a plurality of electric devices 30 of the same module.

Further, when the metal fitting body 2a is directly screwed and fixed to the mounting plate 20 by the screws 11, 11 through the elongated holes 8, 8, as in the prior art, the screw 1
1, the metal fitting main body 2a itself is deformed and cannot be reused. Therefore, in the mounting bracket for an electric device of the present embodiment, the elongated metal screw holes 8 and 8 are not provided. Reinforcing ribs 7, 7 were provided on the edge. The ribs 7, 7 are formed by recessing a metal plate in a groove shape. Further, the width of the bent portion at both end edges of the metal fitting body 2a is configured to be thicker than the conventional one. With these configurations, deformation of the metal fitting body 2a itself due to screw tightening can be suppressed and reuse becomes possible.

FIG. 7 is a view showing an engagement state between the locking claw 4 of the main body fitting 2a of the present embodiment and the locking groove 30a of the electric device 30, but in this embodiment, The locking claw 4 is provided with a step 4a, and an engagement dowel 30b is provided at the bottom of the locking groove 30a to engage with the step 4a. When the main body fitting 2a and the electrical device 30 are hooked and locked, as shown in FIG. 7A, the four locking claws 4 of the mounting bracket for the electrical device are respectively connected to the four locking claws of the electrical device 30. After being inserted into each of the locking grooves 30a, the electric device 30 is slid in the direction of the arrow in the figure with respect to the mounting bracket 2 for the electric device. Then, as shown in FIG. 7 (b), the engaging dowel 30 goes over the tip of the locking claw 4 and engages with the step 4a, and the hook-shaped tip of the locking claw 4 is Groove end 30c of the locking groove 30a
And the electric device 30 is connected to the metal fitting body 2a.
Hooked and locked. That is, by engaging the step portion 4a and the engagement dowel 30b, a feeling that the locking claw 4 is completely locked in the locking groove 30a is generated, and the locking claw is formed with a small force. 4 cannot be easily removed from the locking groove 30a, and the electric device 30 can be firmly and removably attached and fixed to the metal fitting body 2a.
