Description

[Detailed Description of the Invention] The present invention relates to a moderation mechanism for a slide switch. In the moderation mechanism of a conventional slide switch, a concavo-convex portion serving as a moderation generating means is fixedly provided on the inner surface of a switch casing, and a surface of a slider facing the concave-convex portion is provided to freely slide within the casing. In addition, a slider has been widely used in which the slider is moved with moderation by interposing an action ball biased by a spring.

The present invention provides a new moderation mechanism with a simple structure that does not impair the conventional comfortable moderation generation.Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

In the figure, reference numeral 1 denotes a switch casing, and an arc-shaped guide groove 4 partitioned by arc walls 2 and 3 is formed at the rear of the inner bottom surface of the switch casing. Also,
In front of the arcuate wall 3, a shaft-shaped pin 6 is provided on the bottom surface near the side wall 5 of the casing, and an arbitrary number of blind holes 8 for receiving one end of the compression spring 7 are provided in the front surface of the arcuate surface 3. It is being Reference numeral 9 denotes a movable moderation plate according to the present invention, which has a shaft hole 10 at one end that is rotatably supported by a shaft pin 6 provided on the bottom surface of the casing, and a back surface corresponding to the blind hole 8. An arbitrary number of blind holes 11 are formed to receive the other end of the compression spring 7, and on the opposite side there is a moderation generating uneven portion 12 that generates moderation in cooperation with a moderation pin 16 provided on the lower surface of the slider, which will be described later. is formed.

On the other hand, the slider 13 has a spring-biased contact 14 on its upper surface, and two guide pins 15, 15 on its lower surface that fit into the arcuate guide groove 4 and slide left and right. A moderation pin 16 that cooperates with the moderation plate 9 is integrally provided at the front apex position of an isosceles triangle whose base is a line connecting these two guide pins. A cylindrical roller 17 is rotatably attached to the pin to facilitate sliding movement of the slider 13.

Reference numeral 18 is an operating lever provided in front of the slider, and reference numeral 19 is a terminal plate having a fixed terminal that comes into contact with the contactor 14.

As shown in FIG. 2, this slider 13 has guide pins 15 on the lower front surface fitted into guide grooves 4 on the bottom of the casing, and a moderation pin 16 on the lower front surface of the movable moderation plate 9 pushed forward by a spring 7. It is assembled so that it is in contact with the uneven parts of the
It is closed from above by a terminal plate 19.

The compression spring 7 can be set in one of several blind holes by applying pressure to the moderation plate 9.

Next, the operation will be explained.

Now, as shown in FIG. 2, the slider 13 is engaged with the right end concave portion of the moderation generating unevenness portion 12 of the moderation plate 9. When the lever 18 is actuated to the left from this position, the slider is regulated by the arc-shaped guide groove 4 and moves to the position while making a fan-shaped movement. The installed moderation pin 16 moves to the moderation recess of the device and switches the circuit.

In addition, since the movement locus of the moderation pin 16 is a circular arc-shaped locus centered on the guide groove 4, when moving from to to, etc., the convex portion between the concave portions is pressed against the biasing force of the spring 7. It is something to do. Therefore, the moderation plate 9 rotatably supported by the shaft pin 6 is
The left and right movement of the actuating lever 18, in cooperation with the moderation pin 16, performs a rocking motion with a rhythmic moderation corresponding to the undulating shape of the moderation generating uneven portion 12.

FIG. 3 shows another embodiment according to the present invention, in which the guide groove 4 is linear and provided in the front of the casing, and the torsion coil spring 7 is installed in the rear of the casing.
By using a, the uneven portion of the moderation plate 9 is brought into pressure contact with the moderation pin 16.

As described above, the present invention includes a slider 13 that slides inside a casing 1, and a moderation plate 13 that is biased by a spring member and one end of which is rotatably supported by a shaft pin 6. It is designed to generate moderation through the cooperative action of
It has the following effects.

(1) Since the moderation plate is a separate body, it can be easily set up with any moderation generation unevenness, and can be replaced extremely easily.

(2) The mounting position of the spring member can be set arbitrarily, and the operating force of the operating lever 18 can be changed depending on this position.

(3) By combining 1 and 2 above and the length of the actuating lever 18, many types of switches that generate comfortable moderation can be set with a small number of parts.

As described above, the present invention has great practical utility value.
