Factors affecting the life of spring thimble

　　Due to the development of science and technology, electronic and electrical products are developing towards refinement, ease of installation and long service life. The volume of the spring charging pin is telescopic design, which can meet the needs of electronic and electrical products, so the spring charging pin is used by many manufacturers. The service life of the spring charging needle can determine the service life of electronic products, so what factors will affect the service life of the spring charging needle?

　　1. Friction and corrosion: The friction of the spring charging needle during work and various corrosive media in the working environment will reduce the service life of the spring charging needle.

　　2. Electrical failure: Generally, electrical failure refers to a problem with the connection between the wire and the terminal, which directly affects the service life of the spring charging pin. In order to solve this problem, there is now an enhanced new type of crimping technology, which is an upgraded version of the traditional crimping technology. After testing, it was found that this technology can greatly reduce electrical faults, and it has been gradually used in actual production.

　　3. Plugging problem: The plugging and unplugging of the spring charging pin is an important reason that affects its service life. It is very difficult to control the plugging force. If it is small, it is easy to fall off, and if it is large, it is easy to damage. Nowadays, most of them control different insertion and extraction forces according to different places of use, which can ensure the application of some spring charging pins to a certain extent, but cannot completely solve this problem.

　　The above points are the reasons that have a greater impact on the service life of the spring charging needle, and are also more difficult to solve. If the above problems can be solved, the service life of the spring charging pin will be longer, which will also make the spring charging pin more widely used.
