Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a switch device for audio equipment, communication equipment, etc.

(b) Prior Art Conventionally, as this type of device, those shown in FIGS. 3 and 4 are known.

That is, 1 is a micro switch having a pressing part 2 and a terminal 3, 4 is a resin bracket having a switch storage part 5, a mounting part 6, and an opening part 8, and 21 is a resin bracket having a push button part 22, an arm part 23 and a round hole. 24 is a pressing member provided.

Terminal 3 of micro switch 1 is connected to printed circuit board 1
4 is soldered and fixed, and the bracket 4 has the micro switch 1 stored in the switch storage section 5.
The mounting portion 6 is mounted in a mounting hole (not shown) of the printed circuit board 14.

A projection 15a provided on the upper case 15 is fitted into the round hole 24 of the pressing member 21, and the pressing member 21 is rotatable about the projection 15a in the direction of the arrow.
By pressing the push button part 22, the pressing part 2 of the micro switch 1 is pressed, and the micro switch 1 is operated.

In this conventional device, the arm portion 23 is formed long and thick because the pressing operation of the pressing member 21 requires a rotational movement close to a reciprocating movement without any play in the vertical and horizontal directions. Therefore, it has been difficult to make the device smaller and thinner due to the space occupied by the arm.

(c) Problems to be solved by the invention This invention solves problems in conventional devices, namely by improving the structure of the pressing member, which has been a major obstacle in making devices smaller and thinner. The present invention provides a thinner switch device.

(d) Means for solving the problem The present invention stores the switch in the switch storage part of the bracket, inserts the leg of the push button into the guide hole of the bracket, and engages the flange of the push button with the locking claw of the bracket. By stopping the push button, the push button can be mounted on the bracket so as to be freely pressed while restricting the movement of the push button in the horizontal and vertical directions.

(E) Function The push button can be pressed smoothly in the vertical direction because its horizontal movement is restricted by inserting the leg into the guide hole of the bracket, and its vertical movement is restricted by the locking claw of the bracket. It will not fall off the bracket.

(f) Examples The present invention will be explained below with reference to FIGS. 1 and 2. FIG. 1 is an exploded perspective view of one embodiment of the present invention.

Reference numeral 1 designates a micro switch, which has a pressing portion 2 at an upper portion 1a and a terminal 3 at a lower portion 1b. Reference numeral 4 denotes a resin bracket, and a switch storage portion 5 and a mounting portion 6 having an engaging claw 7 at the tip are provided at two locations on the side surface of the main body. Two guide holes 9 are provided on the upper surface 4a of the bracket 4, sandwiching an opening 8 that communicates with the switch housing 5, and a locking claw 10 is inserted into the opening 8.
They are arranged opposite to each other perpendicularly to the line connecting the guide holes 9 at two locations with the guide hole 9 in between. A push button 11 has two legs 12 that are slightly thinner than the guide hole 9 of the bracket 4 described above, and a collar 13 is provided around the push button.

Next, the assembly of the device of the present invention will be explained. Second
The figure is a side sectional view of the device of the present invention. After soldering the terminals 3 of the micro switch 1 to the printed circuit board 14, connect the engaging claws 7 of the left and right mounting sections 6 of the bracket 4 to the printed circuit board 14 so that the switch storage section 5 of the bracket 4 stores the switch 1. Engage with the mounting hole (not shown). When bracket 4 is attached to printed circuit board 14 in this way, switch 1
The pressing part 2 is exposed from the opening 8.

Next, the two legs 12 of the push button 11 are inserted into the guide hole 9 of the bracket 4, and the locking claws 10 of the bracket 4 arranged opposite to each other are pushed apart using the elasticity of the resin, and the flange 13 of the push button 11 is pushed open. is locked by the locking claw 10.

Then, since the lower surface 11a of the push button 11 is located above the pressing portion 2 of the switch 1, the switch 1 is operated by pressing the push button 11 in the direction of the arrow. At this time, the horizontal movement of the push button 11 is regulated by the guide hole 9 of the bracket 4, and the vertical movement of the push button 11 is regulated by the locking pawl 10 of the bracket 4, and the push button 11 is prevented from falling off from the bracket 4. Prevented.

The upper case 15 is provided with a through hole 17, and the push button 11 is configured to protrude from the through hole 17 and be operated.

(g) Effects of the invention As explained above, according to the invention, the horizontal and vertical movements of the push button can be restricted by the structure of the bracket, so there is no need for long and thick arms like in conventional devices. This allows devices to be made smaller and thinner.
