The current general high-voltage connector system integrates a high-voltage interlock function inside the lock while providing multiple lock options. Through the logic sequence of the high-voltage interlock, the connector system with the high-voltage interlock can be disconnected when energized, and the power terminal and the interlock terminal will be connected/disconnected in sequence. In the design of such automotive high-voltage connectors, most of the terminals use a 90-degree or 180-degree plug design to provide EMI shielding in addition to the high-voltage interlock function. And the entire connection system will use a wide temperature and wire diameter range to adapt to many hybrid and pure electric vehicle applications.
