Description

Technical Field

[0001] The present invention relates to the field of wire harness terminal crimping equipment, and specifically relates to a crimping component. Background Art

[0002] During the processing of wire harnesses, it is necessary to crimp wires and terminals. There is no component for crimping the exposed conductive wire area of the wire. During the crimping process of the wire core and the terminal, there is a situation where the terminal leaks the core wire. That is to say, the core wire in the wire is not completely crimped and wrapped by the terminal, resulting in the scrapping of the terminal and the wire, which is not conducive to ensuring the crimping yield.
