Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a switch operating device used in electronic equipment such as radio receivers.

2. Description of the Related Art Generally, a switch operation device for an electronic device is formed by arranging a horizontal switch on a printed wiring board so that force can be transmitted in a straight line. Further, a hinge portion serving as an operating member is integrally formed on one side of the cabinet, and is formed long in a plane to enhance the hinge effect.

A conventional switch operating device will be described below with reference to the drawings. FIGS. 3 and 4 show a conventional switch operating device. Figures 3 and 4
In the figure, 1 is a cabinet, and 2 is an operation button, which is provided at the tip of a hinge 3 integrally formed on one side of the cabinet 1. 4 is a horizontal switch, which is soldered onto the printed wiring board 5. Here, an operating button 2 is held by a hinge 3 integrated with the cabinet 1, and an operating portion 4a of a horizontal switch 4 soldered to a printed wiring board 5 is opposed to the operating button 2 in line with the operating button 2. or,
The hinge 3 is formed to be long in plane with respect to the cabinet 1 in order to enhance the hinge effect.

In the switch operating device configured as described above, when the operating button 2 is pressed, the operating button 2
bends due to the hinge effect of the hinge 3 and presses the operating section 4a of the model switch 4 to operate it.

Problems to be Solved by the Invention However, with the above configuration, there is no flexibility in the arrangement of the horizontal switch 4 and the operation button 2, and there is no flexibility in the arrangement of the horizontal switch 4 and the operation button 2. The disadvantage was that the operation became unstable due to variations in the gap a. Furthermore, there is a limit to the length of the hinge 3 to be increased in order to improve the hinge effect, making it difficult to obtain a stable hinge effect.

In view of the above-mentioned problems, the present invention provides a switch operating device that can absorb variations in the gap a and ensure a stable hinge effect in a narrow range.

Means for Solving the Problems In order to solve the above problems, the switch operation device of the present invention has a tongue piece on the inner surface side of the tip inside the recess formed on one side of the cabinet, using the side wall of the recess. The present invention is characterized in that a hinge is formed, and an operating portion of a vertical switch soldered onto a printed circuit board is opposed to the side surface of the tongue in the rotational movement range of the hinge.

Function The present invention has the above-mentioned configuration, and by making the length of the hinge L-shaped, it is possible to increase the stable hinge effect, and by having the operating point on the side of the tongue, it is inexpensive and stable. This has the advantage of allowing the use of tall vertical switches.

Embodiments Hereinafter, a switch operating device of the present invention will be described with reference to drawings of embodiments.

1 and 2 show a switch operating device according to a first embodiment of the present invention. Figure 1,
In FIG. 2, 11 is a cabinet, which has a recess 15 on one side thereof. Reference numeral 12 denotes a hinge, which has a tongue piece 13 at its tip as an operation button. Here, the hinge 12 is constructed using the side wall of the recess 15 and has a substantially L-shape. 16 is a vertical switch, and printed wiring board 1
7 is soldered on top. L-shaped hinge 12 integrated with recess 15 provided in cabinet 11
The button 13 is held by the button 12, and the operating portion 16a of the vertical switch 16 soldered to the printed circuit board 17 is opposed to the side surface of the tongue of the button 12.

In the switch operation device configured as described above, by pressing the button 13, the L-shaped hinge 1
The button 13 is bent due to the hinge effect of No. 2, and the operating portion 16a of the vertical switch 16 is operated.

As described above, according to this embodiment, since the L-shaped hinge is formed using the wall surface of the recess provided on one side of the cabinet, the distance between the fulcrum and the point of action can be increased, and , the fulcrum is located behind the point of action and a large action angle can be achieved.
Therefore, by arranging a vertical switch soldered on a printed wiring board to the side of the tongue at the tip of the hinge, it is possible to absorb variations in the gap a, ensure a stable hinge effect in a narrow range, and ensure reliable switch operation. operations can be performed.

Effects of the invention As described above, according to the invention, an L-shaped hinge having a tongue on the inner surface of the tip is formed using the side wall of the recess formed on one side of the cabinet.
While pressing the inner surface of the tip, the rotational fulcrum of the hinge is located on the outer edge of the side wall of the rear recess, so the operation is easy, and the point of action on the switch is at the tip of the tongue further ahead, so the operation is easy. The switch can be operated with a stroke larger than the stroke, ensuring a stable hinge effect within a narrow range and ensuring reliable switch operation.
