Description

Technical Field

[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the components that are bundled to form a circuit connection, after the contact terminal (connector) made of copper material is crimped with the wires and cables, and then covered with an insulator or an additional metal shell.

[0003] Automotive wires are different from ordinary household wires. They are generally copper multi-core soft wires. Some soft wires are as thin as hair. Several or even dozens of soft copper wires are wrapped in plastic insulating tubes (polyvinyl chloride), which are soft and not easy to break. Due to the particularity of the automotive industry, the manufacturing process of automotive wiring harnesses is also more special than other ordinary wiring harnesses. Usually, automotive wiring harnesses are manufactured by manual operation. Workers need to pull the wires little by little until the wire tube is passed to the specified position. This method has high work intensity, low efficiency, and poor precision, and cannot meet the needs of large-scale mass production.

[0004] Existing automatic pipe threading equipment can generally only use a certain type of pipe for pipe threading operations, and its application scope is relatively narrow. Utility Model Content
