Factors that affect the life of spring thimble by friction

　　Now almost everyone has a mobile phone and other electronic devices, and more and more electronic devices are used with the development of technology.

　　Current electronic and electrical products are developing in the direction of refinement, ease of installation and long service life. The spring charging needle is small in size and has a retractable design, which can well meet the needs of current electronic and electrical products. Therefore, the spring charging needle is Many connector manufacturers like it. The service life of electronic and electrical products is one of the issues that people are most concerned about. The service life of electronic products depends on the service life of the spring charging pin to some extent. So what factors will affect the service life of the spring charging pin?

　　1. Friction and corrosion: The friction of the spring charging needle and the corrosive substances 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 is also the reason that directly affects the service life of the spring charging pin. In order to effectively solve this problem, there is currently an enhanced new type of crimping technology, which is an upgraded version of the previous crimping technology. Through testing, this technology can reduce electrical failures to a large extent, and has been gradually applied to actual production.

　　3. Plugging problem: The plugging problem of the spring charging pin is an important reason that affects the service life of the spring charging pin. The plugging force is difficult to control, it is easy to fall off if it is small, and it will be damaged if it is large. Nowadays, the most widely used method is to control different insertion and extraction forces according to different places of use, which can ensure the use of some spring charging pins to a certain extent, but cannot completely solve this problem.

　　The above three points are factors that have a greater impact on the service life of the spring charging needle, and are also several problems that are more difficult to solve. If the above problems are solved, the service life of the spring charging needle will be prolonged, which will also make the application of the spring charging needle more extensive.
