Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved mounting device for a microswitch operated via an actuator.

For example, a vending machine is equipped with many selection buttons, and by inserting coins into the vending machine and pressing the appropriate selection button,
It is now possible to purchase desired items. In such an article vending mechanism, when the selection button is pressed, an actuator of a microswitch is activated via an actuator, and the electric signal from the microswitch operates the article vending mechanism. .

By the way, conventionally, the above-mentioned microswitch is fixed to a board provided in correspondence with a selection button with two screws. The actuator has been incorporated into a microswitch, or the microswitch has been attached with a fixing screw. Therefore, with this configuration, a tool for tightening the screws must be used to attach the micro switch or actuator, which is time consuming and has a problem of poor workability. Furthermore, the workability is not as good when it is removed for repair or inspection as when it is installed.

This idea was made based on the above circumstances,
The purpose is to provide a microswitch mounting device that allows the microswitch and actuator to be easily attached and detached without using screws, thereby improving workability.

Hereinafter, one embodiment of the present invention will be explained based on drawings in which it is applied to a vending mechanism of a vending machine.
is the main body that constitutes the operation section of the sales mechanism. As will be described later, the main body 1 consists of a front plate 2 attached to the front of the vending machine and a base plate 3 vertically protruding from one side of the front plate 2 approximately at the center.
A first opening 4 is formed in one side of the front plate 2 partitioned by the substrate 3, and a second opening 5 is formed in the other side.

A display lamp 6 is provided in the first opening 4 so as to project therefrom. In other words, this indicator lamp 6
, a mounting plate 8 extends from one side of the housing 7. A pair of first engaging pins 9, 9 having elastically deformable engaging portions 9a are attached to the periphery of the first opening 4 so as to connect the engaging portions 9a, 9a to the mounting plate 8.
They are protruded from each other so that they are slightly narrower than the width of the two. Then, the indicator lamp 6 is assembled by inserting the housing 7 into the first opening 4, and elastically engaging both sides of the mounting plate 8 with the engaging portions 9a, 9a of the first engaging pins 9, 9. Let it be.

Further, the substrate 3 of the main body 1 has a second opening 5.
A pair of first mounting pins 1 on opposite sides
0 and 10 are spaced apart and protrudingly provided. These first
In the vicinity of the mounting pins 10, 10, there is an engaging portion 11.
A pair of second engaging pins 11, 11 which are elastically deformable and have a diameter 11a are provided in a spaced apart manner so that their engaging portions 11a, 11a are opposed to each other. Furthermore, a second mounting pin 12 is provided protruding near the first mounting pin 10 that is closer to the second opening 5 . The substrate 3 has a pair of mounting holes 13a, 1
3a, the micro switch 13 has its mounting holes 13a, 13a fitted into the first mounting pins 10, 10, and one side is elastically inserted into the engagement portions 11a, 11a of the second engagement pins 11, 11. They are engaged and attached. Furthermore, the second mounting pin 1
2 includes a winding portion 1 having an actuator 14 formed at one end of the actuator 14 made of, for example, a belt-shaped leaf spring.
4a are fitted together. This actuator 14 has one second winding portion near the winding portion 14a.
The second end is held between the engaging pin 11 of the micro switch 13 and the end face of the micro switch 13, and the middle part faces away from the actuator 13b of the micro switch 13, and the other end is bent into a substantially U-shape. It protrudes from the opening 5.

The main body 1 configured as described above is fixed to the inner surface of a panel 15 of the vending machine with screws 16 through a connecting hole 2a formed in one end of the front plate 2. A through hole 17 is bored in the panel 15 so that a portion corresponding to the main body 1, that is, the indicator lamp 6 is exposed. Furthermore, a selection button 18 is provided on the inner surface of the panel 15 with one end pivotally attached. A midway portion of the selection button 18 protrudes from the through hole 17, and the other end abuts a U-shaped portion of the actuator 14 protruding from the second opening 5 of the front plate 2 of the main body 1. Therefore, by pressing the selection button 18, the actuator 14 is displaced using the clamped portion near the winding portion 14a as a fulcrum, and the midway portion moves toward the micro switch 1.
The actuator 13b of No. 3 is operated by pressing.

The main body 1, the first and second mounting pins, and the first and second engagement pins are integrally molded from synthetic resin.

According to the above configuration, the microswitch 13 and the actuator 14 can be attached to the substrate 3 without using screws. That is, the micro switch 13 has its mounting holes 13a, 13
If a is inserted into the first mounting pins 10, 10,
The second engaging pins 11, 11 are elastically deformed and these engaging parts 11a, 11a are connected to the micro switch 13.
This micro switch 1
3 can be attached to the substrate 3. On the other hand, in order to remove the micro switch 13 from the board 3, the pair of engaging pins 11, 11 are inserted into these engaging parts 11a,
11a is elastically deformed in the direction of separation, the side surface of the micro switch 13 and the engaging portions 11a, 11a are disengaged, and the micro switch 13 is inserted into the first mounting pins 10, 10 from the mounting holes 13a, 13a.
Just remove it in the direction that it will come out. Further, the actuator 14 can be attached and detached by fitting and removing the winding portion 14a onto the second mounting pin 12.

Therefore, the microswitch 13 and the actuator 14 can be easily attached to and detached from the substrate 3 by hand without using any tools.

Further, the indicator lamp 6 held on the substrate 3 by the first engaging pins 9, 9 can also be attached and detached by elastically deforming the first engaging pins 9, 9 in the same way as the micro switch 13 described above. Can be done.

As described above, the present invention has a pair of first
A pair of elastically deformable engagement pins having a mounting pin and an engagement portion are provided protrudingly, and the first mounting pin is inserted into the mounting hole of the microswitch, so that a part of the microswitch is fitted with the above-mentioned engagement pin. A winding part is formed at one end of the actuator made of an elastic material, and the winding part is fitted onto a second mounting pin protruding from the substrate to connect the middle part of the actuator. Since they are arranged to face the actuator of the microswitch, the microswitch and actuator can be attached to the board without using screws as in the conventional case. Therefore, there is a practical effect that the microswitch and actuator can be easily and efficiently attached to and detached from the substrate without using any tools.
