Description

[Detailed Description of the Invention] The present invention relates to a push button mounting structure in electronic equipment such as a car stereo.

Conventionally, the mounting structure for pushbuttons with large operating strokes, such as the eject button of a car stereo, has generally been as shown in FIG. On the other hand, elastic engaging pawls 15 are provided at both ends of the lower surface of the push button 12 to engage with the rear side of the mouth edge 14 of the push button mounting window 13.
15 is provided in a protruding manner, and the push button 12 is attached to the push button mounting window 13 by strongly pushing in while aligning the engaging claws 15, 15 with the mouth edge 14.

However, in the above-mentioned conventional device, the engaging claw 15 is strongly bent during installation, causing breakage, and a large force is also applied to the panel side during installation, causing damage to the area around the push button mounting window 13. A certain degree of wall thickness is required, and the push button mounting window 13 cannot be placed near the edge of the panel, resulting in a dead space at the edge 16 of the panel.

The purpose of the present invention is to solve the above-mentioned drawbacks of the conventional ones, to prevent the application of excessive force when attaching a pushbutton to a pushbutton mounting window, and to make it possible to attach a pushbutton to the edge of a panel, thereby making it possible to attach a pushbutton to an electronic device. The purpose is to provide a mounting structure.

Hereinafter, the configuration of the present invention will be explained based on FIGS. 2 and 3, which are examples thereof.

In the figure, reference numeral 1 denotes a car stereo panel, in which a push button mounting window 3 is formed so as to be located on the end side of the panel surface, and one side edge of the push button mounting window 3 is opened in the side plate of the panel 1. 2.
Reference numeral 4 denotes a push button to be attached to the push button mounting window 3, and a hook-shaped portion 5 is provided at the left and right ends of the back surface 6 of the push button.
A protruding engaging claw 5 having a shape a is formed, and a protrusion 6a that comes into contact with the switch is formed at the center of the back surface 6.

Reference numerals 7 and 7 designate guide portions formed on the rim of the opening 2 so that the engaging claw 5 can pass through when the push button 4 is attached through the opening 2, and the hook-shaped portion of the engaging claw 5. It serves as an escape groove for 5a. Therefore, the push button 4 can be inserted into and removed from the push button mounting window 3 from the direction of arrow A, and no unreasonable force is applied during mounting. Further, a restraining plate 8 is formed on the panel 1 so as to be located within the push button mounting window 3, so that when the push button 4 is pressed, the back surface of the restraining plate 8 comes into contact with the panel 1 to prevent the push button 4 from being buried excessively. It's summery. Note that the restraining plate 8 has a recess 8 into which the protrusion 6a of the push button 4 is loosely fitted.
A is provided.

Reference numeral 9 denotes an illumination plate made of a light guide, which is attached to the push button 4 when the push button 4 is attached to the push button mounting window 3, and which emits light from a light source (not shown) arranged on the back side of the panel 1. The position of the push button 4 is displayed by guiding light. 10 is a panel 1 so as to close the opening 2 side of the push button mounting window 3.
This is a decorative board placed on the side panel of the Of course, this decorative board may also be attached so as to cover the entire front surface of the panel 1.

According to the push button mounting structure for an electronic device according to the present invention, there is provided a push button mounting window formed in a panel of the electronic device and having one edge open, and a locking member that engages with the edge of the push button mounting window. A push button provided with a matching claw, a guide portion provided in the push button mounting window so that the engaging claw can be inserted from the opening edge side, and a closing member for closing the opening edge side of the push button mounting window. Therefore, when attaching the push button to the push button mounting window, no excessive force is applied, and there is no need to consider the strength of the engaging claw or the push button mounting window, and there is no need to worry about breakage of the engaging claw. There is no possibility that this will occur. Furthermore, since the pushbutton can be attached to the end of the panel surface, there is no dead space as in the conventional case, and the present invention is particularly suitable as a pushbutton mounting structure for a car stereo with a high mounting density on the panel surface.

In addition, since a lighting plate made of a light guide is placed on the push button when the push button is attached from the opening edge side of the push button mounting window, the light from the light source placed on the back side of the panel is guided to the push button. The position of the object can be reliably displayed by optical display.
