The role of metal plating in automotive connectors
1. The anti-corrosion function of automobile connector plating.
The first consideration for automotive connectors is corrosion resistance. Today, most EV connector contact shrapnel are mostly made of copper alloys, which are susceptible to corrosive effects such as oxidation and vulcanization in a typical EV connector operating environment.
2. The coating of automotive connectors helps to improve mechanical properties.
The parameters related to the mechanical function of the new energy vehicle connector are mainly factors affecting the durability of the coating or the wear-fit force. If these factors are taken into account, then there will be two different factors under the action of the same fundamentals. That is, the sharing of multi-point contact interfaces during relative motion in cold welding. Important mechanical properties include the hardness, ductility and friction coefficient of the coating material, and these properties need to depend on the inherent properties of the coating material and its application. Depending on the workflow, the plating of automotive connectors is very important.
