The stationary piece structure includes a stationary piece frame, two stationary elastic pieces integrally mounted on the stationary piece frame, and a spring installed between the stationary elastic pieces and the stationary piece frame. The bottom of the base has a receiving cavity, and the Hall element is fixedly disposed in the receiving cavity. This relates to the field of Hall sensor switch technology. By setting a stationary piece structure and setting a spring between the stationary piece frame and the stationary elastic pieces, even if the elasticity of the stationary elastic pieces weakens, the spring force can generate an elastic force on the stationary elastic pieces to compensate for the weakened elasticity, ensuring a firm and reliable contact between the stationary elastic pieces and the wiring post, thus ensuring the stability of the wiring.

Description

Technical Field

[0001] This utility model relates to the field of Hall sensor switch technology, specifically a Hall sensor magnetic shaft switch. Background Technology

[0002] Typically, the conduction principle of a push-button switch is achieved by the up-and-down movement of a guide core, which triggers the conduction component to open and close, thus realizing the push-button switch's on / off function. The conduction component usually consists of a stationary contact and a moving contact. The conduction core triggers the moving contact of the moving contact to come into contact with and separate from the stationary contact of the stationary contact to achieve the on / off function.

[0003] When a push-button switch is used for a long time, the moving contact of the moving plate and the stationary contact of the stationary plate frequently come into contact and separate. Over time, the elasticity of the moving plate and the lens weakens, resulting in insufficient contact between the moving plate and the lens, which affects the stability and safety of the push-button switch, and may even cause it to fail to perform the on and off functions. Summary of the Invention

[0004] In view of the problems existing in a Hall sensor magnetic shaft switch, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a Hall sensor magnetic shaft switch, which solves the problem that when a push-button switch is used for a long time, the moving contact of the moving plate and the stationary contact of the stationary plate frequently come into contact and separate. Over time, the elasticity of the moving plate and the lens weakens, resulting in insufficient contact between the moving plate and the lens, which affects the stability and safety performance of the push-button switch, and may even lead to the inability to achieve the on and off functions.

The stationary piece structure includes a stationary piece frame, and two stationary elastic pieces integrally formed on the stationary piece frame. A spring is installed between the stationary elastic pieces and the stationary piece frame.

[0007] In a preferred embodiment of the Hall sensor magnetic shaft switch described in this utility model, the bottom of the base has a receiving cavity, and the Hall element is fixedly disposed in the receiving cavity.

[0008] In a preferred embodiment of the Hall sensor magnetic shaft switch described in this utility model, a support and stabilizing ring is provided inside the receiving cavity, and the support and stabilizing ring is sleeved on the wiring plug.

[0011] In a preferred embodiment of the Hall sensor magnetic shaft switch described in this utility model, the conductive sheet has wire terminals, and the base has a through hole for external wires to pass through and connect to the wire terminals.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] This utility model provides a Hall sensor magnetic shaft switch. Please refer to [link / reference]. Figure 1-4 The system includes a base 1, with a housing 2 connected to the top of the base 1. The base 1 and the housing 2 are fixed together by bolts. A switch moving plate structure is slidably connected to the housing 2. A Hall element 10 is mounted on the base 1. A stationary plate structure is fixedly connected to the top of the Hall element 10, and a wiring plug 5 is fixedly connected to the bottom of the Hall element 10. The stationary plate structure includes a stationary plate frame 9, on which two stationary elastic plates 91 are integrally formed. A spring 16 is installed between the stationary elastic plates 91 and the stationary plate frame 9. Figure 2 As shown, spring 16 is in a compressed state at this time.

[0020] The base 1 has a receiving cavity 13 at its bottom, and the Hall element 10 is fixedly disposed in the receiving cavity 13. A support and stabilizing ring 11 is disposed in the receiving cavity 13, and the support and stabilizing ring 11 is sleeved on the wiring plug 5.

[0021] The base 1 has a notch 6 at its bottom and an L-shaped through hole 12 that connects the notch 6 and the receiving cavity 13. The L-shaped through hole 12 allows for heat dissipation of the Hall element 10. The base 1 has a mounting block (not shown in the figure) on its outer bottom. The mounting block has mounting holes and can be used to fix the base 1. The notch 6 prevents the base 1 from fully contacting the object supporting the switch, thus ensuring the heat dissipation effect of the Hall element 11.

[0022] The switch moving plate structure includes a lifting plate 4 that is slidably connected to the base 1. A conductive plate 7 is fixedly connected to the bottom of the lifting plate 4, and terminals 8 are welded to both ends of the conductive plate 7.

[0023] The conductive sheet 7 has a wire terminal 71, and the base 1 has a through hole 18 for external wires to pass through and connect to the wire terminal 71.

[0024] The top of the encapsulation shell 2 is equipped with a U-shaped plate 3, and the top of the lifting plate 4 is integrally provided with a pull plate 15. The pull plate 15 passes through the U-shaped plate 3 and is slidably connected to the U-shaped plate 3. The top of the lifting plate 4 is provided with a groove, and a magnetic block 14 is embedded in the groove. When the magnetic block 14 is in contact with the U-shaped plate 3, the magnetic block 14 can be magnetically attracted to the U-shaped plate 3, thereby preventing the lifting plate 4 from descending.

[0025] The bottom outer wall of the U-shaped plate 3 has an integral fixing block 31, which is fixed to the encapsulation shell 2 by bolts.

[0026] The spring 16 has a first mounting plate 101 and a second mounting plate 102 welded to its two ends respectively. The first mounting plate 101 and the second mounting plate 102 are respectively connected to the static spring plate 91 and the static plate frame 9 by bolts.

[0027] In practical use, such as Figure 2 As shown, at this time, the terminal 8 is inserted between the two static elastic plates 91, and the two static elastic plates 91 deform and clamp the terminal 8; even if the elasticity of the static elastic plate 91 weakens, the elastic force of the spring 16 can generate elastic force on the static elastic plate 91 to compensate for the weakening of the elasticity of the static elastic plate 91.

[0028] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
