Description

TECHNICAL FIELD The present invention relates to a push switch case mounting structure for mounting a case accommodating a push switch to a mounting member such as a panel of an automobile.

(Prior Art) Conventionally, in this type of push switch case, as shown in FIG. 7, a case 22 having a locking claw 21 is fitted into a mounting hole 5 formed in a panel 4 from the outside to perform the locking. Nail 21
By engaging with the inner edge of the mounting hole 5, it is attached with one touch, and it cannot be easily pulled out from the outside.

(Problems to be Solved by the Invention) However, in such a one-touch push switch case mounting structure, the case 22 is removed from the panel 4 when the parts such as the valve are replaced or the push switch body is replaced due to a switch failure. When detaching, it is usually impossible to work from the inside, so it was necessary to forcibly pull out from the outside to remove the locking claw 21. Therefore, the locking claw 21 is damaged and the locking function is impaired, the case 22 cannot be used again, and the vicinity of the mounting hole 5 of the panel 4 is deformed or scratched. there were.

The present invention has been made in view of such problems, and an object thereof is to provide a push switch case mounting structure that can be easily mounted and dismounted from the outside.

(Means for Solving Problems) In order to solve the problems, the present invention accommodates a mounting member having a mounting hole and a push switch, and
A case in which a flange portion and an engagement hole that come into contact with the outer edge of the mounting hole are formed, and the case is covered.
The case has a first claw portion that locks from the inside at the edge of the engagement hole, and a second claw portion that projects to the outside of the engagement hole and that locks at the tip to the inside edge of the mounting hole. And a cover formed with elastic legs having elastic pieces.

(Example) Next, one example of the present invention will be described with reference to the drawings.

In FIG. 1, 1 is a case for accommodating the push switch 2, 3 is a cover for covering the case 1, and 4 is a panel as a mounting member for fitting the case 1 into the mounting hole 5 for mounting.

The case 1 has a flange portion 1a that abuts the outer edge of the mounting hole 5 of the panel 4 around the surface thereof, an operation hole 7 through which the knob 6 of the push switch 2 projects in the center, and a cover on the side surface. The engaging hole 8 from which an elastic piece 13 of 3 described below projects
have.

The cover 3 has gate-shaped guides 9 on both sides thereof and elastic leg portions 10 standing upright in the respective guides 9. The elastic leg portion 10 has a first claw portion 11 in the middle which engages with the edge of the engagement hole 8 of the case 1 when the cover 3 is mounted on the case 1. Further, the elastic leg portion 10 has an elastic piece 13 protruding to the outside of the engagement hole 8 of the case 1 at the tip of the first claw portion 11 when the cover 3 is attached to the case 1, and When attached to the panel 4, the elastic piece 13 has a second claw portion 12 that is locked to the edge of the mounting hole 5. Here, the spring rigidity of the elastic piece 13 is smaller than the spring rigidity of the elastic leg portion 10.

In the case 1 and the cover 3 having the above-described configurations, first, as shown in FIG. 2, the elastic leg portion 10 is bent inward and biased, and the cover 3 is inserted into the case 1 together with the push switch 2. At this time, the cover 3 is guided by the guide 9 along the inner surface of the case 1, so that the push switch 2 can be stably operated without shaking or rattling at the time of insertion.
Can be inserted.

Then, at the moment when the cover 3 covers the case 1, the first claw portion 1
1 reaches the engagement hole 8 and, as shown in FIG. 3, the elastic leg portion 10 biased at the time of insertion is restored by its elasticity, so that the first claw portion 11 is locked to the edge of the engagement hole 8. At the same time, the elastic piece 13 and the second claw portion 12 thereof project outside the engagement hole 8. Therefore, the cover 3 is securely fixed to the case 1 by locking the first claw portion 11 to the edge of the engagement hole 8, and it is not necessary to use a fixing component such as a screw.

When the case 1 is fitted into the mounting hole 5 of the panel 4 in this state, as shown in FIGS. 3 and 4, the engaging hole 8 of the case 1 is inserted.
At the same time that the more protruding second claw portion 12 gets over the edge of the mounting hole 5 and locks inward, the flange portion 1a abuts the outer edge, and the mounting of the case 1 is completed. Here, when the second claw portion 12 gets over the edge of the mounting hole 5, the elastic piece 13 bends inward, but the elastic leg portion 10 has a larger spring rigidity than the elastic piece 13 and does not bend. Therefore, there is no possibility that the first claw portion 11 will come off and the cover 3 will come off.

The case 1 can be removed from the panel 4 by strongly pressing the knob 6 of the push switch 2.
That is, as shown in FIG. 5, when the knob 6 is strongly pushed, the locking of the first claw portion 11 is released, and the elastic piece 13 is inserted into the engaging hole 8.
Since the second claw portion 12 is disengaged while retracting and retracting inward of the case 1, the case 1 can be pulled out from the mounting hole as shown in FIG. Here, in order to make it easy to release the locking of the first claw portion 11, the edge of the engagement hole 8 that locks with the first claw portion 11 may be formed to be slightly inclined as shown in the figure. preferable.

(Effects of the Invention) As is apparent from the above description, according to the present invention, the push switch case can be easily attached to and detached from the attachment member. Further, in spite of the structure having a small number of parts, the push switch and the cover can be attached / detached to / from the case with one touch.
