Description

Technical Field

[0001] The utility model relates to the technical field of cable continuity detection, and more particularly to a wireless configurable wire harness detection device. Background Art

[0002] Cabinet products in the railway industry require electrical wiring to ensure the normal operation of railway equipment. Typically, the production of a set of cabinets involves a large amount of wiring work. At the same time, the internal wiring will be adjusted according to different configuration requirements. Before the cabinet is powered on, the overall wiring status of the cabinet needs to be tested to determine the correctness of the connection and whether there are any circuit breaks. For a long time, wiring continuity testing has required the cooperation of multiple people. Using a multimeter, multiple groups of cables are tested for continuity one by one in sequence, and the test results are recorded manually. This method consumes a lot of manpower and time, resulting in low production efficiency. Cable continuity testing cannot be completed in some unoccupied and small locations, and manual measurement makes it difficult to achieve 100% accuracy in test results. Utility Model Content
