Description

[Detailed Description of the Invention] This invention relates to a mounting device for an operation button for operating a button switch provided inside the equipment in an audio equipment or the like.

Conventionally, there has been an operation button mounting device with a large surface area as shown in FIG.

Fig. 1 is a partially sectional front view, in which 1 is an operation panel, 2 is a bushing mold fitted into a through hole of this operating panel, and 3 is a bushing mold that can be slid freely into this bushing mold. The inserted operating button, 4 is a holder fixed to the tip of the sliding part 3a of this operating button, 5 is interposed between this holder and the bushing mold 2, and the operating button 3 is moved in the direction of the bushing switch 6. It is a spring that biases the

In the conventional device configured as described above, when the operation button 3 is pressed, the bushing switch 6 is turned on by being pressed by the sliding portion 3a.

At this time, the button switch 6 is locked and the operation button 3
The insertion position shown by the solid line is maintained by the pressing force of the spring 5.

Next, when the operation button 3 is pressed again, the button switch 6 is unlocked and the operation button 3 is pushed back, returning to the protruding position shown by the dashed line 3b, and the button switch 6 is turned off.
It will be in state F.

Since the conventional operation button mounting device is configured as described above, the operation button 3 is attached in order to hold the spring 5.
In addition to the main body, a holder 4 was required as a separate part, and the holder had to be attached after the spring was attached.

When the holder 4 is integrated with the operation button 3, the diameter of the spring 5 must be larger than the maximum diameter of the design part on the front of the operation button 3, and in that case, the operation button must be placed closer to the back of the operation panel. The disadvantage was that it had to be incorporated.

This invention was made in order to eliminate the drawbacks of the conventional ones as described above, and by integrating the operation button 3 and the holder 4, and fitting the spring 5 after incorporating it into the bushing mold 2, the number of parts can be reduced. It is an object of the present invention to provide an operation button mounting device which has the same function as the conventional one and can act on an operation button having a large surface area with a small diameter spring.

An embodiment of this invention will be described below with reference to the drawings.

Fig. 2 is a perspective view showing the state before installation, and Fig. 3 is a perspective view showing the state after installation. In the figures, 1 to 5 indicate the same or equivalent parts as in Fig. The portion 3a is made of a plate-shaped body having a smaller cross-sectional area than the design portion on the front surface of the operation button 3, and the holder 4 is integrally formed at the tip of this sliding portion 3a.

7 is a through hole provided in the bush mold 2 to receive the sliding part 3a, and 8 is provided on both sides of this through hole to receive the sliding part 3a.
9 is an H-shaped hole provided in the sliding part 3a and into which the spring 5 is inserted; 10 is a rib provided at the tip of this hole to hold the spring 5; 11 is a sliding hole; This is an elastic claw-shaped stopper provided at the tip of the portion 3a.

To install the operation button 3, first insert the sliding portion 3a in the direction of arrow A through the through hole 7 of the bushing mold 2.

A stopper 11 consisting of an elastic claw of the sliding part 3a bends inward when sliding with the guide 8 of the bush mold 2, and opens outward after passing through the guide 8 to prevent it from falling off.

When the button 3 is inserted all at once into the bushing mold 2 and the spring 5 is inserted into the through hole 9 of the sliding part 3a, the spring 5 connects to the holder 4 consisting of the tip of the through hole 9 and the rib 10, and the bushing. It is held between molds 3.

The state after assembly is as shown in FIG.

This device is constructed as described above, and the operation of the operation button 3 is the same as that shown in FIG.

Although a rectangular button is used as the operation button 3 in the above embodiment, it may be circular or other shapes, and the shape of the sliding portion is not limited to that shown in the drawings, and other shapes can be used.

Further, the stopper 11 may also have a different structure as long as it can prevent the sliding portion from falling off.

This invention is applicable not only to audio equipment but also to the operation of bush switches in other equipment.

As above 1. According to this invention, the operation button and holder are integrated to reduce the number of parts, and a small diameter spring can act on the operation button with a large surface area.In addition, when installing the operation button, it is possible to insert it from the operation panel surface. In addition, the spring can be inserted after the operation button is inserted, making the work easier, and the guide and stopper are provided, which has the effect of preventing the operation button from wobbling or falling off. .
