Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mounting structure for push buttons arranged in communication equipment, audio equipment, etc., and relates to a mounting structure that can be easily configured and assembled.

(Prior Art) A conventional mounting structure for a push button for operating a push switch disposed on the back side of a panel in communication equipment, audio equipment, etc. has been configured as shown in FIGS. 1 and 2, for example.

In this mounting structure, a decorative panel 21 having buttonholes 21a and a sub-panel 22 disposed on the back side thereof are used, and the sub-panel 22 includes a mounting collar 2 that protrudes from the back surface of the decorative panel 22.
3 by tightening the screw 24. A switch mounting base 25 is protruded from the back side of the sub-panel 22, and a micro switch 26 is mounted on this with screws 2.
The screws are tightened at 7. The push button 28 consists of a large diameter part 28a serving as an operation part and a small diameter part 28b formed at the rear end.The large diameter part 28a projects from the button hole 21a, and the small diameter part 28b is formed in the subpanel 22. A coil spring 29 is interposed between the large diameter portion 28a of the push button and the sub panel 22, and is arranged to protrude rearward from the through hole 22a and correspond to the operating portion 26a of the micro switch 26. In addition, the pushbutton 2 above
A circumferential groove 2 is provided in the small diameter portion 28b to prevent the part 8 from falling off.
8c, and an "E" ring 30 is fitted therein.

However, the above-mentioned device requires a sub-chassis 22, a mounting collar 23, a screw 24, an E-ring 30, etc., which increases the cost due to the large number of parts and makes the installation work troublesome. It had drawbacks such as requiring a large space for installation.

(Purpose of the invention) The purpose of the invention is to eliminate the drawbacks of the conventional push button mounting structure described above, reduce the number of parts, reduce costs, and facilitate the installation work. An object of the present invention is to provide a mounting structure for a push button, which allows the mounting of a push button.

(Structure of the invention) The pushbutton mounting structure according to the invention includes a switch mount protruding from near the button hole formed in the panel to the back side of the panel, and a push button attached to the switch mount to be pressed. The pushbutton is arranged so that it slides using the switch mount as a guide.
In the pushbutton mounting structure, the pushbutton is actuated by pushing the pushbutton against a spring means interposed between the pushbutton and the pushbutton, wherein the switch mounting base has a plate shape, and the pushbutton has a button hole. A roughly semicircular flange that abuts the operating part of the push switch is integrally molded on the rear end of the operating part that protrudes from the flange, and guide parts are formed on both sides of the lower end of the flange, and the guide part is adapted to slide by engaging with the side edge of the switch mount, and one end of the coil spring serving as the spring means is inserted into a fitting recess formed at the rear end of the operating part of the push button. It is also characterized in that it is held by a guide projection formed in the center of the fitting recess.

(Example) An example of the push button mounting structure according to the present invention will be described based on FIGS. 3 and 4.

In the figure, 1 is a panel, 2 is a plate-shaped switch mounting base protruding from near the button hole 3 on the back side of the panel 1, and a micro switch 5 is mounted on a positioning boss 4 provided at the rear of the top surface. After the two are engaged, they are screwed together with a screw 6 through the screw holes 2a and 5a.

Reference numeral 7 designates a push button body which is inserted from the back side of the panel so that the operating section 8 protrudes from the button hole 3 of the panel 1, and has a substantially semicircular shape at its rear end that abuts the operating section 5b of the micro switch 5. The flange portion 9 is integrally molded, and the flange portion 9
Guide portions 10 are provided at the lower ends of both sides so as to be able to slide onto the switch mount 2, so that the operating portion 8 is disposed so as to be freely retractable from the button hole 3.

Reference numeral 11 denotes a spring means such as a coil spring placed between the micro switch 5 and the push button body 7, and when installing it,
A fitting recess 12 is formed in the operating portion 8, and a guide protrusion 13 is provided in the center thereof, and one end of the coil spring is inserted into the fitting recess 12 so as to be held by the guide protrusion 13. This prevents the coil spring from shifting.

(Effect of the invention) According to the push button mounting structure according to the invention, the switch mounting base that should protrude from the back side of the panel is in the form of a plate, and the push button is attached to the rear end of the operating part that protrudes from the button hole. A roughly semicircular flange that comes into contact with the operating section of the push switch is integrally molded, and guide portions are formed on both sides of the lower end of the flange, and the guide portions engage with the side edges of the switch mount. Since the switch mounting base and the push button are designed to slide together, it is not only easy to mold the switch mounting base and the push button, but also ensures reliable sliding action. Since the coil spring is inserted into a fitting recess formed at the rear end of the operating section and is held by a guide protrusion projected at the center of the fitting recess, the coil spring can be arranged in a small space. There are effects such as being able to reliably prevent the spring from shifting.
