Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a mounting device for a switch used in a portable electric light or the like.

Conventional configuration and its problems As shown in Fig. 1, in the conventional installation of this type of switch, the operation button 2a of the switch 2 protrudes outward from the inside of the box-shaped case 1, and in that state, the case 1 is Switch cover 3 made of rubber etc. from the outside
cover the operation button 2', and then screw the screw 4 through the switch cover 3 and the case 1 to the switch 2'.
The switch 2 was installed by screwing it into the flange portion 2b of the switch. However, with this configuration, the assembly operation is very troublesome and time consuming, and the waterproof effect is extremely uncertain as it depends on the tightening condition of the set screw 4.

Purpose of the invention In view of the above-mentioned conventional problems, it is an object of the present invention to make it possible to install a switch with simple work and to ensure its waterproof effect.

Structure of the Invention In order to achieve the above object, the present invention provides a holding member that holds the flange part of the waterproof switch cover in a superposed state on the flange part of the switch, and also connects this holding member to the waterproof switch cover. The switch cover is inserted into the case so as to protrude outward from the opening hole of the case, and a rail-shaped projection is provided on the side wall of the inner surface of the case,
By inserting an elastic mounting member between the upper surface of this projection and the holding member from the end opening side of the case, the ring-shaped projection provided on the upper surface of the flange of the waterproof switch cover can be attached to the upper surface of the case. It is configured to be pressed against the inner surface of the case. According to this structure, when attaching the switch to the case, a mounting member with elastic force is attached to the top surface of a rail-shaped protrusion provided on the inner side wall of the case to hold the switch, etc. The switch can be installed by simply inserting it from the open end side of the case between the holding member and the holding member, which simplifies the installation process compared to the conventional screw fastening process.As a result, assembly work efficiency is improved. In addition, the waterproof effect of the switch can be improved by pressing the ring-shaped protrusion provided on the upper surface of the flange of the waterproof switch cover against the inner surface of the upper part of the case.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In Figures 2 and 3, 11
1 is a headlight case (hereinafter referred to as the case) which has an open end and an opening hole 12 on the top surface.The end opening of this case 11 has a front base (sometimes (not shown) is removably attached. Reference numeral 13 denotes a rail-shaped projection integrally formed on the left and right side walls of the inner surface of the case 11;
Reference numeral 4 designates a switch that is mounted in the case 11 so that an operation button 15 projects outward from the opening hole 12. A flange portion 16 is formed on the upper outer periphery of the switch 14. 17 is the switch 14
This waterproof switch cover 17 is made of rubber and has a ring-shaped protrusion 19 on the upper surface of the flange 18. is forming. 20 is the switch 14
A holding member that holds the flange portion 16 of the waterproof switch cover 17 and the flange portion 18 of the waterproof switch cover 17 in an overlapping state, and a groove 21 is provided at the lower outer peripheral edge of the holding member 20 at opposing positions. There is.
Reference numeral 22 denotes a mounting member inserted between the upper surface of the protrusion 13 provided on the case 11 and the holding member 20. This mounting member 22 is made of synthetic resin and has a U-shape. groove 21
Convex portions 23 that elastically engage are provided at opposing positions.

In the above configuration, the switch 14 is connected to the case 11.
When installing the switch 14 on the flange 16 of the switch 14 and the flange 18 of the waterproof switch cover 17, first hold them with the holding member 20 in an overlapping state, and then attach the holding member 20 to the waterproof switch cover 17. The mounting member 22 is inserted into the case 11 so as to protrude outward from the opening hole 12 of the case 11, and then the mounting member 22 is inserted between the upper surface of the protrusion 13 of the case 11 and the holding member 20 in the direction of the arrow. By inserting the mounting member 22, the convex portion 23 of the mounting member 22 elastically engages with the groove 21 of the holding member 20, and the mounting is completed. With this installation,
Since the ring-shaped protrusion 19 provided on the upper surface of the flange portion 18 of the waterproof switch cover 17 comes into pressure contact with the inner surface of the case 11, the switch 14 can be reliably waterproof.

In addition, in one embodiment of the present invention, the holding member 2
0 is provided with a concave groove 21, and a convex portion 2 is provided on the mounting member 22.
3 is provided, but conversely, the holding member 20 is provided with a convex portion, and the mounting member 22 is provided with a convex portion.
A groove may be provided in the groove.

Effects of the invention As described above, according to the invention, when attaching a switch to a case, a mounting member having elastic force is
The switch can be installed by simply inserting it from the open end of the case between the top surface of the rail-shaped protrusion provided on the inner side wall of the case and the holding member that holds the switch, etc., so the installation work is much easier than conventional methods. Compared to screw fastening work, it is extremely simplified, and as a result,
As well as improving assembly workability,
The waterproof effect of the switch is also excellent because the ring-shaped protrusion provided on the upper surface of the flange of the waterproof switch cover presses against the inner surface of the upper part of the case.
