The popularity of electronic products makes current electronic and electrical products tend to be refined, easy to install, and have a 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, so spring charging The needle is loved by many connector manufacturers. People are most concerned about the length of the service life of electronic and electrical products. 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: If there are various corrosive substances in the working environment and friction of the spring charging needle, the service life of the spring charging needle will be reduced.
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 effectively solve this problem, there is now an enhanced new type of crimping technology, which is an upgraded version of the previous crimping technology. After testing, this technology can reduce the occurrence of electrical faults to a large extent, and has been gradually applied in 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. If it is small, it will fall off, and if it is large, it will be damaged. The most commonly used method now is to control the different insertion and extraction forces according to the 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 three points are the reasons that have a greater impact on the service life of the spring charging needle, and they are also more difficult to solve. As long as these problems can be solved, the service life of the spring charging needle will become longer, and the spring will be charged. Needles are more widely used.
