What is the purpose of connector metal plating?

　　Connector is a very important part of the profession of electronic components,and engaged in electronic engineering and technical personnel can be found:most of the connector will be plated with a very special layer of plating.So what is the role of the connector plating in the end?The reason why the connector should have contact plating,this is because the plating can not only maintain the connector to reduce the environment to reduce its corrosion interference,increase the durability of the connector and wear resistance,it can also assist in the establishment and maintenance of stable connector impedance from the electrical function.Specific performance such as:

　　First,the connector plating anti-corrosion function

　　Connector is the first thing to think about that is corrosion maintenance.Today,most of our electrical connector contact shrapnel are made of copper alloy,and copper alloy in the typical electrical connector operating environment that is the most simple to be corroded,such as oxidation and vulcanisation.In fact,the contact plating is used to close the contact shrapnel and the operating environment,and thus isolated,to avoid copper corrosion.Of course,the plating material also needs to ensure that the operating environment is not endangered.

　　Second,the connector plating helps to improve mechanical function

　　And the mechanical function of the parameters related to the first is to affect the durability of the plating or wear and tear and with the elements of the force.If you want to think about these elements,then in the same fundamental role there will be two different points of view,that is,multi-point contact interface in the relative motion process of cold welding sharing.The most important mechanical properties include hardness,ductility and coefficient of friction of the plated material.These characteristics depend on the connotative properties of the plating material and its application of the work process,therefore,the connector plating is very important.
