I was positioning it.

(Problems to be solved by the invention) However, in the above-described conventional device for mounting an electric device, since the plate member is bent to form the rising portion and the collar portion, the bottom surface of the mounting bracket is particularly deformed. It was easily warped, and there were problems in strength such as displacement and fixing.

In addition, when an object collides with an electric device, the mounting bracket is deformed by the external force, and it is necessary to consider using a thick plate to prevent the set light from being out of focus. .

(Means for Solving the Problem) Therefore, a key-shaped protrusion having protrusions formed on the left and right of the bottom surface of the main body of the electric device and a recessed groove, and either one of the protrusions is slidable under back pressure. And a rising part facing from the bottom and a flange part provided outside the rising part to form a flange part, and bent upward in a direction perpendicular to the rising part and between the flange parts. A space is formed to form a side wall to form a mounting metal fitting, the flange portions are fitted between the recessed grooves, and the projection provided on the bottom surface of the electric device is sandwiched between the side walls to be mounted. , To prevent misalignment.

(Operation) The attachment device for an electric device configured as described above is between the member to be attached and the electric device and fixes each other.

Therefore, a hook-shaped protrusion with a groove formed by providing a protrusion on either the left or right side of the bottom surface of the main body of the electric device on the mounting bracket screwed to the member to be mounted, and a similar groove facing the protrusion. The formed slider is arranged so as to be pressed by a leaf spring, and the width of the protrusion is sandwiched between the side walls of the mounting bracket.
The flange portions are fitted and attached between the recessed grooves, and the positioning is fixed.

(Effects of the Invention) As described in detail above, according to the present invention, the following effects can be achieved.

Protrusions are provided on the left and right sides of the bottom surface of the main body of the electric device to form a concave groove, and one of the concave grooves is a slider that is slidable by receiving back pressure. Formed within the width of the main body of the electric device, and provided with a rising part facing from the bottom surface and a flange part by bending to the outside of the rising part, and bending upward in a direction perpendicular to the rising part. Since the side wall is provided, and the projecting piece is further provided to extend in the direction of the flanges on the left and right of the side wall to form the mounting metal fitting, (1) the rising portion bent from the bottom surface of the mounting metal fitting, and its Since a slight gap is provided between the flange part bent outward, the side wall and the projecting piece, a slight strain or deformation can be allowed due to the elasticity of the rising part and the side wall, and the width of the main body of the electric device can be allowed. Since the projections are sandwiched between the side walls also in the direction, it is possible to prevent rattling of the electric device.

Therefore, it has a feature that the mounting member and the electric device can be completely fixed to the front, rear, left and right of the electric device.

(2) Since the mounting holes are provided on the bottom surface and side wall of the mounting bracket, it is possible to mount on the bottom surface and on the side surface in two directions depending on the member to be mounted. Since the work can be done with one touch, maintenance is extremely easy.

(3) For a pair of mounting holes (mounting pitch A) provided on the side surface of the main body of the electric device, the mounting holes (mounting pitch B) provided on the side wall of the mounting metal fittings should be provided at a total of four locations. It is possible to use mounting holes at necessary locations according to the above, and therefore it is possible to mount to various members to be mounted, and it is possible to provide a mounting device for a wide variety of electric devices.

(4) Since the electrical equipment is provided with a protrusion having a width approximately equal to the inner dimension of the side wall of the mounting bracket, the side wall of the mounting bracket will fall or be deformed by the protrusion even if the screws are strongly tightened in the mounting holes provided on the side wall. It can be mounted firmly without performing.
