Problem causing poor pin socket on charge gun terminal

　　There are some small problems in the pin socket on the charging gun terminal. Let's learn about it with the small coding.

　　1、 Unreasonable crimping of pin socket on charging gun terminal causes contact resistance too high and temperature rise too high

　　The crimping contact surface of the cable core and terminal is facing to the point, and there is not enough contact surface.

　　The crimping force is too large, which causes the broken line, which makes the load flow smaller.

　　The crimping force is too small, which causes the poor crimping, which leads to the virtual connection.

　　2、 The material selection of pin socket on the charging gun terminal and the improper selection of coating cause the temperature rise too high after use and burn down

　　The selection of copper core material and the selection of coating will affect the conductivity between the charging gun body and socket, and the hardness of the terminal will be affected by the different materials.

　　The difference is too large, after the times exceed a certain number, the coating on the surface will be damaged to different degrees. The contact resistance generated during the matching is too high, and the temperature rise will also be affected.

　　The treatment of anti-static plug has an effect on the coordination of terminals.

　　3、 The plug of pin socket on the charging gun terminal is easy to fall off

　　The connection between plug and terminal is not reliable and easy to loosen. When the charging gun product is designed, the temperature rises, the plug is easy to fall off, and the structure design has some problems.

　　4、 The accuracy of the pin socket on the charging gun terminal is insufficient, and the coordination between the charging gun and the pin socket is poor, which leads to virtual connection

　　The machining accuracy of copper core is unreasonable and the tolerance is too large, which causes the matching with the pin socket too tight or too loose.

　　The deformation of elastic shape behind the charging socket is unreasonable, which leads to deviation from the matching of copper core.

　　The plug form of charging socket at vehicle end is different, which leads to the inconsistent contact resistance.
