Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating button mounting structure, and more particularly to an operating button mounting structure for electric equipment.

[0002]

2. Description of the Related Art Generally, when operating a switch of an electric device, a structure in which an operation button is pressed to push the switch is used. Then, as shown in FIG. 4, an L-shaped mounting portion 42 is integrally formed on the operation button 41,
The mounting portion 42 is fixed to the housing 40 by screwing or bonding with a screw 43.

Further, in the case of the operation button as shown in FIG. 5, when the right end of the operation button 50 is pressed as shown by the broken line in FIG. 5A, the left end of the operation button 50 rises and the switch 52 does not operate. There is. Therefore, in FIG.
As shown in (b), exactly the same switches 53, 5
4 is provided, no matter where the operation button 50 is pressed, at least one of the switch 53 and the switch 54 is pressed,
I used a switch that operates.

[0004]

However, attaching the operation button to the housing by screwing or adhering has a problem in that the assembly work is troublesome. Further, in order to ensure the switch operation of the operation button, attaching two switches causes a problem of high cost. The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide an operation button mounting structure that is easy to assemble and has high reliability in switch operation.

[0005]

SUMMARY OF THE INVENTION In view of the above, the present invention provides a hook portion for locking an operation button to be pressed and operated integrally with a housing, and engaging the hook portion of the operation button on the housing. It is characterized in that it is configured to have a locking portion for stopping. In addition, a guide is provided in a housing in which an operation button that is pressed and operated is provided, the guide is provided along the pressing direction of the operation button, and the guide and the operation button are arranged close to each other. It is a feature.

[0006]

[Function] Since the operation button is provided with the hook portion for locking the operation button to the housing, and the housing is provided with the locking portion for locking the operation button hook portion, the operation button has the hook portion. It is attached to the housing by being locked to the locking portion. Therefore, screwing work or bonding for attaching the operation button to the housing is not necessary, and the assembling work is facilitated. Further, since the guide is provided close to the periphery of the operation button, the operation button does not tilt when the operation button is pressed. Therefore, the switch is reliably operated by the operation button.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A mounting structure for an operation button according to the present invention will be described with reference to FIGS. 1 and 2 show the first embodiment of the present invention.
It is a figure which shows the Example of. In the drawing, reference numeral 1 denotes a housing, and this housing 1 is provided with an opening 3 for assembling an operation button 2 and a locking hole 1a as a locking portion for fixing the operation button 2 to the housing 1. ing. The operation button 2 is provided with an operation portion 2a, one side portion of the operation button 2 is provided with an abutting portion 2b that abuts the back surface of the housing 1, and the other side portion is provided with the operation button 2 on the housing. An arm portion 2d provided with a hook 2c for attaching to 1 is formed. A pressing portion 2e for pressing the switch is provided on the back surface of the operation portion 2a of the operation button 2.

A tact switch 4 (hereinafter, referred to as a switch) operated by the operation button 2 is assembled to a printed circuit board 5, and the printed circuit board 5 is fixed to the printed circuit board 5 by mounting it on the housing 1. A hole 6 is provided as a means. The housing 1 has a pair of fixing pieces 7 having a substantially U-shaped cross section for fixing the end portion of the printed board 5, and a support having a hook for fixing the substantially central portion of the printed board 5. The piece 8 and the piece 1 are integrally provided on the housing 1 as fixing means.

In the operation button mounting structure thus configured, the hook 2c of the operation button 2 is engaged with the locking hole 1 of the housing 1.
While inserting the operation portion 2a of the operation button 2 into the housing 1
The operation button 2 is attached to the housing 1 by inserting the operation button 2 into the opening 3. Next, the end portions 5a of the printed circuit board 5 are fitted into the grooves 7a of the fixed piece 7, respectively, and are moved in the direction of arrow A. Then, the hooks 8a of the support piece 8 are fitted into the holes 6 of the printed circuit board 5, and the printed matter is printed. The substrate 5 is fixed by the fixed piece 7 and the support piece 8. At this time, the switch 4 on the printed circuit board 5 is arranged at a predetermined position operated by the operation button 2. The operation button 2 can move in the direction of arrow B with the hook 2c as a fulcrum, and
Since the arm portion 2d has flexibility, it is possible to operate the switch 4 with the operation button 2.

3A and 3B are views showing a second embodiment of the present invention. FIG. 3A is a side view and FIG. 3B is a plan view of operation buttons. Operation buttons are shown. In this embodiment, the operation button 11 has an elongated shape in plan view, and the operation button 11 is provided with an operation portion 11a and a projection-shaped pressing portion 11b on the opposite back surface. The switch 12 is arranged at a position facing to. A collar 11c is provided on the side of the operation button 11. On the other hand, a guide 14 having a substantially L-shaped cross section is provided in the housing 13 so as to surround the operation button 11. The guide 14 is provided along the pressing direction of the operation button 11, and the operation button 11 and the guide 14 are provided.
And are in close proximity.

In the operation button mounting structure thus constructed, for example, even if the end portion 11d of the operation button 11 is pressed, the side surface 11e of the operation button 11 contacts the guide 14 as shown in FIG. 5 (a). The operation button 11 does not tilt, and therefore, even if the end portion of the operation button 11 is pressed, the switch 12 can be easily operated.

[0012]

According to the present invention, since the operation button is constructed as described above, the operation button can be surely attached by being fitted in the housing, so that the screwing work is unnecessary and the assembling work is facilitated. Play. In addition, since the guide is formed on the housing so that the operation button does not tilt when pressed, it is possible to perform reliable switch operation even with an elongated operation button, and there are multiple switches with similar functions as in the past. There is an effect that a mounting structure with high reliability of operation is maintained without individually mounting.
