Description

Technical Field

[0001] This utility model relates to the field of contact switch technology, specifically a contact switch springback protection structure. Background Technology

[0002] In existing contact switch technology, the contact parts of the switch often lack an effective rebound mechanism after disconnection. This leads to wear of the contact points after frequent operation, thereby reducing the service life of the switch. In addition, due to the lack of rebound protection, the switch may generate an electric arc when disconnecting the circuit. This can not only damage the internal contact materials of the switch, but also potentially damage the machine tool circuit, leading to faults such as open circuits.

[0003] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a contact switch springback protection structure. Utility Model Content

[0004] The purpose of this invention is to provide a contact switch rebound protection structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A contact switch rebound protection structure technical solution includes a pole, a mounting crossbar at the top of the pole, a rebound seat mounted on the mounting crossbar, a stepped groove inside the rebound seat, a spring installed in the stepped groove, a switch button above the spring, and a switch connecting seat at the bottom of the mounting crossbar, the switch connecting seat passing through the crossbar and the rebound seat and connected to the switch button.

[0007] As a preferred technical solution, the stepped groove is engaged with the spring, and the two ends of the spring are respectively in close contact with the switch button and the stepped groove.

[0008] As a preferred technical solution, the mounting crossbar and the surface of the spring seat are provided with an insulating layer, which is used to prevent current leakage.

[0009] As a preferred technical solution, the spring seat is fixedly installed on the mounting crossbar by bolts, and the bottom of the stepped groove is provided with a through opening for connecting the switch connector.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention relates to a spring-loaded protection structure for contact switches, which effectively extends the service life of the contact switches. By incorporating a spring-loaded base and spring inside the switch, it ensures that the contact points rebound quickly after disconnection, thereby reducing wear on the contact points. Simultaneously, the spring absorbs the arc energy generated during disconnection, preventing damage to the internal materials of the switch and the machine tool circuitry from the arc. Furthermore, by providing an insulating layer on the mounting bar and the surface of the spring-loaded base, this invention also prevents current leakage, further improving circuit safety. This invention provides a simple, low-cost, and highly effective spring-loaded protection structure for contact switches. Attached Figure Description

[0013] Figure 2 This is a schematic diagram of a spring structure for a contact switch rebound protection structure.

[0014] In the attached diagram, the following are the reference numerals: 1. Upright pole; 2. Mounting crossbar; 3. Spring-loaded seat; 31. Step groove; 4. Spring; 5. Switch button; 51. Switch connector. Detailed Implementation

[0015] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0016] like Figure 1 , Figure 2 As shown, this utility model provides a contact switch spring-loaded protection structure: a vertical rod 1, a mounting crossbar 2, a spring-loaded seat 3, a stepped groove 31, a spring 4, a switch button 5, and a switch connecting seat 51. The vertical rod 1 serves as the support for the entire structure, with the mounting crossbar 2 at its top, and the spring-loaded seat 3 mounted on the crossbar 2. The spring-loaded seat 3 has a stepped groove 31 inside, and the spring 4 is installed within the stepped groove 31. The switch button 5 is positioned above the spring 4. The switch connecting seat 51 is located on the bottom surface of the mounting crossbar 2, passing through the crossbar 2 and the spring-loaded seat 3, and is connected to the switch button 5.

[0017] The stepped groove 31 is engaged with the spring 4, and both ends of the spring 4 are in close contact with the switch button 5 and the stepped groove 31, respectively. This design ensures that the spring 4 can be compressed when the switch button 5 is pressed and quickly rebound when released, thus achieving rapid rebound of the contact point.

[0018] The mounting bar 2 and the spring-loaded seat 3 are provided with an insulating layer to prevent current leakage. The insulating layer can be any suitable insulating material, such as plastic, rubber, or ceramic coating, to ensure the safety of the entire structure in electrical applications.

[0019] The spring-loaded seat 3 is fixedly mounted on the mounting crossbar 2 by bolts, and the bottom of the stepped groove 31 has a through-hole for connecting the switch connector 51. This design allows the switch connector 51 to be connected to an external circuit while maintaining the stability and reliability of the structure.

[0020] When the circuit needs to be closed, the user presses switch button 5, compressing spring 4, closing the contacts, and allowing current to flow. When the user releases switch button 5, the elastic force of spring 4 causes switch button 5 to quickly rebound, opening the contacts and breaking the circuit. The presence of spring 4 not only ensures rapid rebound of the contacts and reduces wear, but also absorbs the arc energy generated during disconnection, thus protecting the internal materials of the switch and the machine tool circuit from damage. The insulation layer further ensures that current does not leak, improving the safety of the entire circuit system.

[0021] Through the above structure and working method, the contact switch rebound protection structure of this utility model can effectively extend the service life of the contact switch, reduce maintenance costs, and improve the overall safety of the circuit system.

[0022] The working principle and usage process of this utility model: After assembling each component of this solution in sequence, work according to the above implementation methods according to actual needs to complete all working steps.
