What is the standard range of insertion and withdrawal force for charging connectors, and what do excessive or insufficient force indicate?
According to IEC 62196 and GB/T 20234 standards, both single-pin and overall insertion/withdrawal forces of charging connectors have specified limit requirements:
1.Standard scope: For example, per GB/T requirements, the overall insertion force of AC charging connectors is generally no greater than 100 N, and the withdrawal force is no less than 50 N (to prevent accidental disconnection); for DC high-power connectors, due to larger terminal dimensions, the insertion force typically does not exceed 140 N;
2. Excessive insertion/withdrawal force: Possible causes include terminal misalignment, foreign objects or deformation inside the interface, increased friction due to worn terminal plating, or a jammed locking mechanism. Long-term forceful mating accelerates terminal wear and housing damage;
3. Insufficient insertion/withdrawal force: Possible causes include fatigued terminal elastic elements, excessive terminal wear reducing normal force, or loose/retracted terminals at the cable end. Insufficient force causes poor contact, abnormal temperature rise, and even connector disconnection during charging, posing safety hazards.
If a noticeable abnormal change in insertion/withdrawal force is noticed during use, stop using and inspect the interface condition. DEGSON charging connectors are designed with strict terminal normal force control to ensure insertion/withdrawal force stays within the qualified range, while maintaining contact reliability after tens of thousands of mating cycles.
