Description

Technical Field

[0001] The utility model relates to the technical field of wire harness continuity detection, in particular to a wire harness continuity detection fixture. Background Art

[0002] Wire harness continuity detection is a test method for testing whether the wire harness connection is correct. The wire harness is usually composed of multiple wires or leads, which are used to transmit electrical signals from one point to another. The wire harness continuity detection can detect whether the wires or leads in the wire harness are correctly connected, and whether there are short circuits, open circuits or other faults. The detection process is usually carried out using a continuity tester or a domitter. The continuity is judged by passing current through the wires or leads of the wire harness and detecting whether current flows. The commonly used detection device is to connect the plug of the wire harness to the socket and then connect all the lead ends to the detection equipment one by one. However, some wire harnesses have dozens of leads and the leads are thin and soft. If they are connected one by one, it will be a waste of time and lead to low production efficiency. Workers usually manually press the connection structure when plugging and unplugging the plug, which hurts their hands. Utility Model Content
