The influence of different plating metal types on the surface of the pin jack of the car connector

　　The type of metal plating on the exterior of the automobile connector and the thickness of the metal plating have an impact on the service life of the automobile connector, and this method can also be used for the enhancement of the service life of the pin jack of the automobile connector.

　　In short, the thicker the nickel layer of the automotive connector terminal, the stronger the wear resistance of the gold-plated layer; the smoother the surface, that is, the lower the roughness, this will cause the friction to be particularly small; therefore In the process of normal use of the connector, attention should be paid to the maintenance of the electrical connector to reduce human damage to the electrical connector.

　　When connecting the car connector, the pin can be opened with absolute force, and it will be easier when separating, so the car connector needs more force to be inserted than when it is pulled out. Therefore, we must pay great attention to the strength of insertion and removal when solving this problem.

　　The interaction of the forces of inserting and unplugging the automobile connector can easily cause the connector to wear out. For example, if you want to reduce wear, you can increase the strength of the gold-plated layer that contacts the surface, so that friction can be effectively reduced.

　　The most important operation is to be able to plate the outer contact surface of the car connector with nickel first and then gold. This will cause less friction than directly plating gold on copper.
