Description

Technical Field

[0001] The present application relates to the technical field of automobile wiring harness manufacturing, and in particular to an automobile wiring harness connection terminal crimping machine. Background Art

[0002] Wire harness terminals are the connecting ends used for electrical connection in the wire harness system. Similarly, in the automotive wire harness system, in order to achieve quick plug-in of wires, one or both ends of the wires usually need to be connected to terminals, and the terminals are crimped onto the wire cores of the wires through terminal crimping equipment. According to different classification standards, wire harness terminals are divided into many types. In automotive wire harnesses, some wire harness terminals are larger in size and the corresponding wires are thicker. This type of wire harness terminals is mainly used in electrical components that need to transmit larger currents or withstand larger voltages. Compared with the crimping process of small-sized wire harness terminals, for the crimping of large-sized wire harness terminals, a larger and more stable crimping force is required to ensure the electrical contact and mechanical stability of the wire harness terminals in the wire harness, and a higher process precision is required to ensure the accuracy of the crimping position and meet the corresponding crimping standards.

[0003] Currently, when a crimping machine is used to crimp a connection terminal onto a wire harness, an operator places the wire harness on the crimping machine, and the crimping machine cuts the connection terminal from a steel strip and crimps it onto the wire harness. After the connection terminal is crimped onto the wire harness, the end of the connection terminal is wrapped around the waterproof plug, thereby improving the waterproof performance of the wire harness.

[0004] However, when crimping the connection terminals of wire harnesses in batches, the operator takes the bundled wire harnesses with one hand, takes one wire from the bundle with the other hand, and then places the taken-out wire harness on the crimping table of the crimping machine, which results in relatively average crimping efficiency of the wire harnesses.
