Connectors are very important components in electronic products, and those engaged in electronic engineering can also find that most connectors will be coated with a layer of metal coating. So what is the special meaning of plating connectors?
The reason why the connector should have contact coating is that this coating can not only maintain the connector to reduce the corrosion and interference of the environment, but also add the durability and anti-wear ability of the connector. It can also help to establish and maintain a stable connector impedance from the aspect of electrical function.
The specific performance is as follows:
1、 The parameters that help to strengthen the mechanical function and the mechanical function are the factors that affect the durability of the coating, wear and match force. If we want to consider these factors, there will be two different views under the same fundamental role, that is, the sharing of cold welding of multi-point contact interface in the process of relative motion. The most important mechanical functions include hardness, ductility and friction coefficient of coating material. These characteristics depend on the connotation and nature of the coating data and the operation process used. Therefore, the connector coating is very important.
2、 Corrosion maintenance is the first consideration for connectors with anti-corrosion function. Nowadays, most of our electrical connector contact shrapnel are made of copper alloy, which is the easiest to be corroded in a typical electrical connector working environment, such as oxidation and vulcanization. In fact, the contact coating is used to close the contact shrapnel and the working environment, and then isolate to avoid copper corrosion. Of course, the coating materials also need to be protected from harm (at least in the harmful range) in the working environment.
