Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an actuator device for a switch that is installed in a narrow space.

Conventional Structure and Problems With the miniaturization of electronic devices, it has been desired to miniaturize not only various parts but also switches. However, since it is usually not possible to reduce the number of parts,
The actuator device of a switch that is smaller than a certain point has the disadvantage that its operation becomes uncertain and assembly becomes difficult.

In addition, as shown in Fig. 1, the micro switch 1
When operating the micro switch 1 by inserting the knob 2 into a hole of a size similar to the thickness of the knob 2 provided in a cassette (not shown), etc., it is difficult to position the knob 2 and the hole, and the operation may be difficult. There was a problem in that it was uncertain.

Purpose of the invention In view of the above-mentioned drawbacks, the present invention is arranged in a narrow area,
Furthermore, the present invention provides a switch actuator device that operates reliably with minute strokes.

Structure of the Invention In order to achieve the above object, the present invention includes an operation guide shaft portion formed with one end bent upward, a guide shaft portion formed with the other end bent upward, and the guide shaft portion. In this configuration, an actuator having a transmission guide portion formed by bending its upper end in the horizontal direction is mounted together with a microswitch on a mounting plate such that the transmission guide portion of the actuator contacts the knob of the microswitch.

It can be formed with a small number of components, consisting of a mounting plate, an actuator, and a micro switch, and can be operated reliably even with a small stroke.

DESCRIPTION OF EMBODIMENTS A switch actuator device according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 2 is an exploded perspective view of an actuator device of a switch according to an embodiment of the present invention. On the surfaces of the parts 4 and 5, guide holes 6 and 7 provided on the same axis, and a guide slit part 8 provided on the same center line as the guide hole 7,
A switch attachment hole 9 and the like are formed at the other end.

Reference numeral 10 designates an actuator, which includes an operation guide shaft portion 11 with one end bent upward, a guide shaft portion 12 with the other end bent upward, and an end portion of the guide shaft portion 12 bent in the horizontal direction. A transmission guide portion 13 is formed.

Here, between the guide holes 6 and 7 of the bending parts 4 and 5 of the mounting plate 3, the actuator 10 is inserted from the bottom direction.
A guide shaft portion 12 is disposed in the guide slit 8 of the operation guide shaft 11 .

Next, switch mounting hole 9 at one end of mounting plate 3
The convex portion 14 of the micro switch 1 is inserted into the
The microswitch 1 is attached to the mounting plate 3 through the holes 15, screws 16, and nuts 17.

The operating state will be explained with reference to FIG.

When the upper end of the actuator 10 is pressed in the direction of arrow A, the actuator 10 slides while its top and bottom surfaces are guided by the guide holes 6 and 7 of the mounting plate 3 and the guide slit portion 8, and the micro switch 1 Push the knob 2 in the direction of arrow B to operate.

Next, when the pressing force applied to the upper end of the actuator 10 in the direction of arrow A is released, the restoring force of the microswitch 1 acts, and the state shown in FIG. 3 is restored.

Effects of the invention As described above, the switch of this invention operates reliably with a small number of components consisting of a mounting plate, an actuator, and a micro switch, and when assembled, the actuator mechanism can be constructed simply by inserting the parts. It is highly productive and cost-effective, and has great practical value.
