Contact resistance: The contact resistance of a high-voltage connector is usually composed of several parts such as the crimping resistance of its internal conductive terminals, the resistance of the terminal body, and the shrinkage resistance of the pinhole contact area.
Electromagnetic shielding: In order to avoid the electromagnetic field generated by the high-voltage and large current inside the high-voltage connector from interfering with the stability and accuracy of signal transmission, it is usually necessary to perform electromagnetic shielding design on the high-voltage connector.
High-voltage interlock: High-voltage interlock is referred to as HVIL, which is the abbreviation of Hazardous Voltage Interlock Loop. High-voltage interlock refers to a safety design method that uses low-voltage signals to monitor the integrity and continuity of high-voltage circuits.
In addition, the high-voltage interlock function is integrated in the high-voltage connector. It is necessary to ensure that when the high-voltage connector is connected or disconnected, the HVIL circuit is disconnected first and then connected, and a necessary time difference is maintained in the middle.
