The intermittent rotation of the conveyor belt will transport the wiring harness cables forward in a quantitative manner.

[0016] The crimping device for automobile wiring harness cables described in the present invention adopts a structure that drives the first rack to move toward one end when the hydraulic cylinder contracts. The movement of the first rack to one end will drive the baffle to move toward one end. The movement of the baffle to one end will move the cylindrical joint inside the third hollow groove toward the direction of the cable, so that the cylindrical joint can be automatically loaded and moved along the arc plate, and the cylindrical joint can be moved to the outside of the stripped end of the cable.
