Description

[Detailed Description of the Invention] The present invention aims to provide a switch device suitable for ultra-compact, particularly thin electronic equipment.

FIG. 1 shows a conventional switch device commonly used in tape recorders.

In the figure, 1 is a printed wiring board on which electronic components are attached, 2 is a conductive leaf spring fixed to the printed wiring board 1 with pins 3 and 4, and its contact portion 5 is connected to the wiring board 1. It extends vertically.

6 is displaced when the switch is operated, and the conductive leaf spring 2
This is a contact member that comes into contact with and separates from the contact portion 5 of the.

In such a configuration, as the contact member 6 is displaced from the position shown by the solid line to the position shown by the broken line, the contact part 5 of the conductive plate spring 2 is also pressed and displaced from the position shown by the solid line to the position shown by the broken line, thereby performing a switch operation. Let's do it.

In such a switch, it is difficult to shorten the length of the contact part 5 because the elastic force of the contact part 5 makes good contact with the contact member 6. It is not suitable for miniaturization, especially for thinning.

The present invention aims to provide a switch device that is improved in this respect, and will be described below with reference to FIG. 2, which is an embodiment.

In the figure, reference numeral 7 indicates a printed wiring board on which electronic components are attached, and reference numeral 8 indicates one end 9 fixed to one surface of the printed wiring board 7 with a pin 10, and is parallel to the printed wiring board 7 as much as possible. A conductive plate spring is attached to the printed wiring board 7 through a hole 11 formed in the printed wiring board 7.
A contact portion 12 that protrudes from the other surface and is bent in a dogleg shape is formed.

Reference numeral 13 denotes a contact member which is displaced in parallel to the printed circuit board 7 during the switching operation of the switch, and which exerts a switching action by coming into contact with and separating from the contact portion 12 of the conductive plate spring 8.

In such a configuration, when the contact member 13 is displaced from the position shown by the solid line to the position shown by the broken line, the contact member 13 comes into contact with the contact part 12, so that the contact part 12 changes to the position shown by the solid line. It is displaced from the position to the position shown by the broken line.

When the contact member 13 and the contact portion 12 of the conductive plate spring 8 are in the position shown by the broken line, the contact member 13 and the contact portion 12 are in contact with each other, so the switch is in a closed state. become.

When the contact member 13 is moved from this state to the position shown by the solid line, the contact member 13 becomes separated from the contact portion 12 of the conductive leaf spring 8, so that the switch becomes open.

The switch opening/closing operation according to the present invention is performed in this way. According to this switch, the pressing force of the contact member 13 in the direction of the arrow A is bent into the dogleg shape formed on the conductive leaf spring 8. Since the contact portion 12 absorbs the displacement, the amount of displacement in the direction of arrow B, that is, in the direction perpendicular to the surface of the printed wiring board 7 is small, and the thickness can be reduced.

In this embodiment, the contact portion 12 is connected to the hole 11 of the printed wiring board 7.
Although the structure is made to project more toward the opposite surface, it is also possible to provide a notch so as to project toward the opposite surface.

As explained above, the switch device of the present invention has a conductive plate spring attached to one surface of a printed wiring board so as to be parallel to the printed wiring board, and a hole or notch formed in the printed wiring board. The contact portion bent in a dogleg shape is made to protrude through the other surface of the printed wiring board, and the contact member that exerts the switching action is displaced parallel to the printed wiring board. It has the advantage of being able to shorten the length in the direction perpendicular to the surface of the printed circuit board, and the present invention is suitable for ultra-miniaturization, especially thinning, of electronic devices such as tape recorders. .
