The main electrical performance connector electrical performance of the connector comprises a contact resistance, insulation resistance and dielectric strength. ① contact resistance of high-quality electrical connectors should have a low and stable contact resistance. Connector contact resistance from a few cents to tens milliohms range. ② measure the insulation resistance between the electrical connector contacts and the contact member and the insulating properties of the housing waterproof wire connectors index, ranging on the order of several hundred to several thousand megohms megohms. ③ said dielectric strength or resistance, voltage, medium-voltage wire connector suppliers, tolerance is the ability to characterize the connector between contacts or contacts with the housing rated test voltage. Salt spray connector work in an environment containing moisture and salt in, its metal structure, the contact surface treatment layer may produce galvanic corrosion, impact connector physical and electrical properties. In order to evaluate the electrical connector withstand this environment capability wire connector, the salt spray test prescribed. It is the connector hanging in a temperature-controlled test chamber with a predetermined concentration of sodium chloride solution with compressed air ejection plug-in wire connector to form a salt spray atmosphere, the exposure time defined by product specification, at least 48 h.
