The Insulation Integrity Of The Cold-pressed Pin Crimper Should Be Tested Immediately After Crimping.

After the contact crimper crimping is completed, the corresponding crimped terminals and insulation layers need to undergo a rigorous integrity check. For each crimp point, visual and mechanical verification should be performed to confirm that the terminal is not deformed or cracked, the insulation area is completely covered, and the insulated terminal has not pierced the conductor. If the terminal is bent, the brush is in an abnormal position, there is a tapered hole, or the insulation layer is damaged, it should be judged as a failure of crimping d sub contact crimper.

For the insulated crimped portion, tensile and bending tests should be performed according to industry standards. By gently pulling the wire or bending it repeatedly, observe whether there is slippage or cracks between the insulation layer and the conductor, thus determining whether the crimping of the contact crimping tool is secure. If the insulating sleeve cannot properly support the cable, or the wire becomes loose after insertion and removal, this does not meet the crimping specifications.
