Why are electronic connectors with metal plating?

Electronic connectors, often called terminals, are very important components in the electronic components profession, and those working in electronic engineering can also find that most terminals are coated with a very special coating. Then, what is the special meaning of the plating on the terminal? The reason why the terminal should have contact plating is that this coating can not only maintain the terminal to reduce the corrosion of the environment, but also add durability and wear resistance of the terminal. It can help establish and maintain a stable terminal impedance from the electrical function. Specific performance is as follows:

 

First, the terminal plating helps to improve the mechanical function

The parameters related to mechanical function are primarily the factors that affect the durability of the coating or the wear and fit. If you want to think about these elements, then there will be two different views under the same fundamental role, that is, the sharing of cold welding in the multi-touch interface during the relative motion process. The most important mechanical functions include hardness, ductility and the coefficient of friction of the coating data. These characteristics depend on the connotation nature of the coating data and the process of operation used. Therefore, terminal plating is very important.

 

Second, the anti-corrosion function of the terminal plating

The first thing to think about is the corrosion maintenance. Today, most of our terminal contact shrapnel are made of copper alloy, which is the easiest to corrode in typical terminal operating environments, such as oxidation and vulcanization. In fact, the contact coating is used to close the contact spring and the working environment and then separate to avoid copper corrosion. Of course, the coating data also needs to be protected from damage (at least in the harmful range) in the operating environment.
