Description

Technical Field

[0001] The invention relates to the field of wire harness detection equipment, in particular to a cable wire harness detection device. Background Art

[0002] A cable harness is a wire assembly that brings together multiple wires or cables and fixes them into a whole with insulating materials. It is commonly used in automobiles, aircraft, industrial equipment and other fields. A cable harness is usually composed of multiple insulated wires, each of which has its own function and purpose. Each wire has a layer of insulating material on the outside to prevent current short circuits and protect the wires from the external environment. The material of the insulating layer can be plastic, rubber or other insulating materials.

[0003] When testing the cable harness, the existing testing device is connected to the harness connector via the wiring terminal, and the cable is tested by the testing equipment. Since there are multiple wires inside the cable, the wires need to be connected to the wiring terminals in sequence, and the testing operation is cumbersome. In addition, the wire connectors cannot be distinguished and sorted, which is not conducive to subsequent testing and use. When one of the wires needs to be tested, the connectors at both ends of the wire cannot be quickly found. Summary of the invention
