Operation And Inspection When Cold Crimping Needles Produce Smoke

Before operation, a thorough inspection of the overall structure of contact crimper is essential. Check the tightness of the connector, cable contact areas, and power connections, ensuring there is no looseness or dust accumulation. Verify the pressure distribution at the contact points and the conductor specifications against the crimp connector; mismatches will generate additional heat during crimping.

If abnormal smoke appears during the crimping process of d sub contact crimper, operation should be stopped and the mechanical moving parts of the equipment should be visually inspected. Unusual noises or vibrations may indicate wear or insufficient lubrication of mechanical parts, which can cause high temperatures at metal contact surfaces. Regularly cleaning oil and plating residue from the crimp connector and conductor surfaces helps reduce frictional heat and maintain good contact.

Confirm that the power supply parameters are stable and operating within the range specified in the contact crimping tool manual. Under conditions of large load variations or voltage fluctuations, internal coils and control modules may locally overheat, causing smoke. Inspect the connectors and cable insulation for circuit connections; address any signs of damage or melting promptly.
