That is, devices that connect two active devices, transmit current or signal. In all the electronic components that make up the whole system, the connector looks like the structure is simple and can not get attention, but its failure probability is the highest. The three basic features of the connector1. Mechanical performance In terms of connection function, the insertion force is an important mechanical property; another important mechanical property is the mechanical life of the connector. 2. Electrical performance The main electrical performance of the connector includes contact resistance, insulation resistance and electrical strength. 3. Environmental performance Common environmental performance including temperature, moisture, salt spray, vibration and shock. Terminals There are three common types of fatal faults:2. Poor insulation3. Fixed badly The quality of the connector gold-plated layer is one of the important parameters to evaluate the quality of the connector. The base material of the connector is a copper alloy, the surface coating is gold and its alloy, between the base copper and the surface gold plating.
