Why Insert The Cold-pressing Needle Into The Cable Sheath?

Inserting crimp contact male into the cable sheath aims to penetrate the insulation layer, allowing crimp socket contact to directly contact the conductor, establishing a stable electrical path and reducing contact resistance. This also achieves mechanical positioning and uniform contact.

This process originates from the insulation piercing and female crimp contact bonding principles and is commonly used in batch assembly and quality inspection processes. It requires a specialized crimping die, controlled crimping and insertion forces, and is supplemented by non-destructive testing or resistance measurement to determine contact consistency.
