Causes Of Abnormal Temperature At The Connection Point Of The Cold-pressed Needle

female crimp contact plays a crucial role in conductor connections within electrical systems. When male crimp contact is continuously operating, insufficient crimping may create tiny gaps at the contact surface. Current flowing through these high-resistance areas can induce Joule heating, leading to localized temperature increases.

The quality of the crimping process for crimp contact directly affects its conductivity. If the crimping depth of crimp contact pin is insufficient or the crimping force is unevenly distributed, the metal contact area will be reduced. Under prolonged load operation, this poor contact will gradually increase resistance, exacerbating heat generation.
