AI Technical Summary
Existing automotive through-wall connectors are prone to short circuits in lithium battery systems due to protruding bolts, and the risk of short circuits increases when the connector clips loosen under vibration.
The lead-to-lithium countersunk wall connector is adopted, with the connection hole designed as a countersunk hole. The bolt and nut are lower than the surface of the insulating base. Combined with the high insulation performance base material and the one-piece molded structure, it enhances mechanical strength and protection, and avoids tools or clamps from contacting the nut.
It effectively eliminates short-circuit hazards, reduces leakage risks, and enhances resistance to rotational torque. It is suitable for lead-to-lithium conversion upgrades in existing vehicle models and meets the insulation and protection requirements of high-voltage systems.
