Significance of Terminal Plating Application
It can not only reduce the corrosion of the terminal material surface, but also improve the insertion force state. Reduce friction, reduce insertion force The main factors that affect the coefficient of friction between terminals include: material, surface roughness, and surface treatment. When the terminal material is fixed, the friction coefficient between the terminals is fixed, and the relative roughness is relatively large. When the surface of the terminal is treated with a coating, the coating material, coating thickness, and coating finish have a positive impact on the friction coefficient. To prevent oxidation and corrosion after the terminal plating is damaged, the connectors interact with each other through interference fit within 10 effective times of plugging and unplugging. When there is contact pressure, the relative displacement between the male and female terminals will cause the surface of the terminal to move during movement. The coating is broken or slightly scratched, resulting in uneven thickness or even exposure of the coating, resulting in changes in mechanical structure, scratches, adhesion, wear debris, material transfer, etc., as well as heat generation.
