Factors that affect the life of spring thimble in friction

time:2020-11-28 Views:207

  Electronic products are becoming more popular, so that current electronic and electrical products are developing in the direction of refinement, simple installation and long service life. The spring-loaded charging needle is small in size and has a retractable design, which can solve the current electronic and electrical products. Therefore, the spring charging pin has been favored by many connector manufacturers. Nowadays, people are more concerned about the service life of electronic and electrical products. The service life of spring charging pins can also determine the service life of electronic products to some extent. So what factors will affect the service life of spring charging pins?

Factors that affect the life of spring thimble in friction(图1)

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

  2. Electrical failure: Electrical failure usually refers to a problem with the connection between the wire and the terminal, which is also a direct factor in 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. Through 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 factor affecting 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 is easy to damage when it is large. The most commonly used method is to control 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 points are the reasons for the relatively large impact on the service life of the spring charging needle, and it is also a relatively difficult problem to solve. As long as the above mentioned problems can be solved, the service life of the manufactured spring charging needle will become longer. , Which can also make the application of spring charging needles more extensive.
