Description

Technical Field

[0001] This utility model relates to the field of miniature detection switch technology, and specifically to a miniature detection switch. Background Technology

[0002] A miniature detection switch is a small switching device used to detect the position, state, or action of an object. Specifically, a miniature detection switch changes its internal mechanical structure or electronic components through actions such as touching, pressing, or approaching an external object, thereby opening or closing the circuit and outputting a signal to the control system. For example, a mechanical miniature detection switch uses external force to deform an internal spring to make contact and conduct the circuit; while a photoelectric switch determines the object's position or state by detecting the object's blocking or reflection of light. However, conventional push-button switches with spring contacts have a large spring travel range and insufficient contact and rebound response speed, resulting in insufficient switch sensitivity and failing to meet the requirements of detection switches. Therefore, a miniature detection switch is provided to solve these problems. Utility Model Content

The first terminal and the second terminal are disposed on the same side of the adhesive base, and the third terminal and the fourth terminal are disposed on the other side of the adhesive base.

[0005] In a preferred embodiment of this utility model, the first terminal is opposite to the third terminal, the second terminal is opposite to the fourth terminal, the first terminal and the third terminal are both independent terminals, and the second terminal and the fourth terminal are both non-connecting terminals.

[0006] As a preferred embodiment of this utility model, the outer sides of both ends of the rubber base are provided with bayonets, and the bayonets are matched and engaged with card plates, which are disposed at both ends of the iron shell.

[0007] As a preferred technical solution of this utility model, the iron shell has a limiting port at the end opposite the button, the button extends to the outside of the limiting port, and the card plate has a T-shaped structure.

[0008] As a preferred embodiment of this utility model, the contact end of the contact piece is directly opposite the first terminal and the third terminal, and the spring piece fits into the interior of the rubber base.

[0009] The present invention has the following advantages: by using the iron shell in conjunction with the clips on both sides to snap onto the top of the rubber base, the spring, contact piece, and button can be quickly encapsulated inside the rubber base, resulting in a compact structure and convenient assembly and disassembly.

[0010] The product is assembled from terminals, rubber bases, springs, contact pieces, buttons, and a metal shell.

[0016] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to the following: Figures 1-4 This utility model discloses a miniature detection switch, including: a rubber base 1, terminals and a pressing assembly. The pressing assembly includes a spring 10, a button 11 and a contact piece 13. A shaft groove 12 is provided inside one side of the upper end of the rubber base 1. One end of the button 11 is movably connected inside the rubber base 1 through the shaft groove 12. The spring 10 is located below the button 11 and the contact piece 13 is located between the button 11 and the spring 10.

[0020] The terminals include a first terminal 2, a second terminal 3, a third terminal 4, and a fourth terminal 5. The first terminal 2 and the second terminal 3 are located on the same side of the base 1, and the third terminal 4 and the fourth terminal 5 are located on the other side of the base 1. The first terminal 2 and the third terminal 4 are opposite to each other, and the second terminal 3 and the fourth terminal 5 are opposite to each other. The first terminal 2 and the third terminal 4 are both independent terminals, and the second terminal 3 and the fourth terminal 5 are both non-connecting terminals.

[0021] The rubber base 1 has a bayonet 6 on both outer sides, and a locking plate 7 is matched and locked on the bayonet 6. The locking plate 7 is set at both ends of the iron shell 8. The iron shell 8 has a limit port 9 at the end facing the button 11. The button 11 extends to the outside of the limit port 9. The locking plate 7 has a T-shaped structure. The contact end of the contact piece 13 is facing the first terminal 2 and the third terminal 4. The spring piece 10 fits into the inside of the rubber base 1. Through the spring piece 10, the pressing distance of the button 11 is shortened, so that the terminal and the contact piece 13 make quick contact, and the detection switch responds faster.

[0022] Specifically, in this utility model, the iron shell 8, together with the two side clamping plates 7, is fastened to the top of the rubber base 1, thereby quickly encapsulating the spring piece 10, contact piece 13, and button 11 inside the rubber base 1. In use, simply press the button 11 located outside the limiting port 9, and the button 11 will press the spring piece 10 and the contact piece 13, thereby causing the contact piece 13 to simultaneously contact the first terminal 2 and the third terminal 4, thereby quickly realizing the circuit connection. When the hand stops pressing the button 11, under the elastic force of the spring piece 10, it can automatically rebound and push the button 11 back to its original position, thereby lifting the contact piece 13 to disconnect the circuit between the first terminal 2 and the third terminal 4.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
