Description

Technical Field

[0001] The present invention relates to the technical field of wire harness terminal processing, and specifically relates to a wire harness terminal processing device for automobiles. Background Art

[0002] An automotive wire harness is the network main body of an automotive circuit. Without a wire harness, there would be no automotive circuit. A wire harness refers to a component formed by crimping contact terminals made of copper material onto a wire and cable, and then externally molding an insulator or adding a metal housing, etc., and bundling the wire harness to form a circuit connection. The wire harness industrial chain includes wire and cable, connectors, processing equipment, wire harness manufacturing, and downstream application industries. The wire harness is widely used in automobiles, household appliances, computers and communication equipment, various electronic instruments and meters, etc.

[0003] When processing existing automotive wire harness terminals, crimping is required. However, the exposed wire cores of the wire harness are sometimes in a scattered state. After the scattered wire cores are inserted into the terminal, some wire cores will be outside the terminal in a divergent state. After the crimping operation, the terminal is only crimped to some of the wire cores, resulting in an unstable crimping effect of the processing device. Summary of the Invention
