Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a push button used in audio equipment, video equipment, etc. In particular, it is possible to control the amount of pushing of the push button, and prevent damage to the hinge due to overstroke and damage to the switch. This invention relates to a push button that can be prevented from being damaged.

[Conventional technology]

As shown in FIGS. 4 and 5, in the conventional push button, the integrally formed spring portion of the push button main body 3 is fixed to the boss 10 of the front panel 1, and when the push button is pressed, the push rod 31 moves to the base plate 5. A structure is used that operates a switch 4 attached to the switch.

[Problem that the invention attempts to solve]

The conventional push button as described above does not have a means for regulating the amount by which the push button is pressed, and has the disadvantage that if the push button is operated many times with overstroke, the spring portion may be damaged or the switch may be damaged.

[Means for solving problems]

The present invention was devised for the purpose of providing a push button that can solve the problems of the prior art as described above, and includes a push rod provided on the back of the push button body, the lower surface of the push button body extended, A spring portion bent downward at a right angle from the extension portion is integrally molded with resin, and the lower end of the spring portion is fixed to a boss on the panel side, and the tip of the pressing rod is a stopper integrally provided on the front panel. When the push button is inserted through the slit of the stopper and pressed against the spring section, the amount by which the push button is pressed is regulated by the slit section of the stopper.

[Effect]

According to the push button of the present invention, when the push button is pushed in, the push rod 31 is regulated by the slit 12 of the stopper 11 that is integrally provided on the front panel, so that the spring part may be damaged or the switch may be damaged. does not occur.

〔Example〕

EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention is demonstrated based on the Example shown in drawing.

In the drawings, FIG. 1 is an exploded perspective view of the push button of the present invention as seen from the back, FIG. 2 is a sectional view of the main part, and FIG. 3 is a sectional view of the main part when the push button is pushed in. 4 is a partial perspective view of a conventional push button seen from the back, and FIG. 5 is a sectional view taken along line A--A in FIG. 4.

In the description of the push button of the present invention and the conventional push button, common parts are indicated by the same reference numerals.

In the push button of the present invention, a tapered pressing rod 31 that becomes thinner toward the tip is integrally provided on the back surface of the push button body 3. Further, the lower surface of the push button main body 3 extends inward of the front panel 1, and is integrally provided with a spring portion 2 bent downward at a right angle from the tip of the extension portion.

On the other hand, a stopper 11 having an inverted L-shaped cross section is integrally provided on the front panel 1 from the upper edge of the opening 13. Also, opening 1
A boss 10 is integrally provided at an inner position below 3.

At the position where the lower part of the spring part 2 is fixed to the boss 10 by the screw 21, the tip of the pressing rod 31 is inserted into the slit 12 provided in the stopper 11. At this time, as shown in FIG.
It comes into contact with the upper end of the body to restrict outward movement.

Further, as shown in FIG. 3, when the push button is pushed against the spring portion 2, the tip of the push rod 31 comes into contact with the switch 4 attached to the base plate 5, and is activated. At this time, the back surface 32 of the push button comes into contact with the inner surface of the stopper 11, and the amount by which the push button body 3 is pressed is regulated.

[Effect of idea]

Since the present invention has the configuration as explained above,
The pushing amount of the push button is regulated, and there is no damage to the spring part or damage to the switch due to overstroke, which is the case with conventional switches.
Furthermore, since the structure is simple, space is saved even when the switches are connected in series, and assembly is easy.

[Brief explanation of the drawing]

The drawings show an embodiment of the present invention. Figure 1 is an exploded perspective view of the push button of the present invention seen from the back, Figures 2 and 3 are sectional views of the main parts, and Figure 4 is a view of the conventional push button. FIG. 5 is a partial perspective view seen from the back, and a sectional view taken along the line A--A in FIG. 4. 3...Push button body, 31...Press rod,
2...Spring part, 11...Stopper, 12...Slit, 4...Switch, 32...Back side of push button.

Claims (1)
