What Causes A Heavy-duty Connector To Fail Waterproof, Resulting In Poor Touch And A Circuit Breaker?

The M16 cable gland at the end of heavy duty 2 pin connector has requirements on cable gripping force and torque resistance. The standard says that the tensile strength of heavy duty connector 16 pin reaches 80N and the torque resistance value is greater than 0.45N.m. However, in actual use, heavy duty connector 5 pin may be subject to strong artificial pulling and twisting. In this way, the actual data of heavy duty connector 6 pin may be far from the standard value. Moreover, this force is maintained between the two heavy duty electrical contacts for a long time. After long-term field use at heavy duty industrial connector, it usually ends up causing heavy duty male female connector to be not waterproof or with poor contact and thus break the circuit.
