Hidden Causes Of Abnormal Temperature Rise In Cold-pressed Pins And Terminal Chain Damage

In the maintenance conditions of crimp contact, temperature rise-related faults are often misdiagnosed as material problems of crimp contact pin. More common clues after disassembly come from the geometry of the crimping points, the crimping force curve, and the conductor compression ratio deviation.

On the production line side, it is recommended to use quantifiable methods for control: crimp socket contact Crimping height should be randomly inspected with gauges; crimping force or stroke curves should be monitored for trends; pull-out force should be used as a batch threshold; and microslicing should be used to locate abnormal compression ratios and flaring problems. Lubrication or oil contamination can alter crimping force and cause fluctuations in crimping height; tool wear can also amplify these discrepancies.
