Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness continuity testing technology, specifically to a multi-station parallel intelligent testing device for automotive wiring harness continuity. Background Technology

[0002] Automotive wiring harnesses are the core of a vehicle's electrical network; without them, there is no automotive electrical system. A wiring harness is an assembly consisting of copper-plated contact terminals (connectors) crimped to wires and cables, then covered with a molded insulator or an outer metal shell, and bundled together to form a connected circuit. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing, and downstream application industries. Wiring harnesses have a wide range of applications, including automobiles, home appliances, computer and communication equipment, and various electronic instruments. Body wiring harnesses connect the entire vehicle body and are generally H-shaped.

[0003] Automotive wiring harnesses differ from ordinary household wiring. Ordinary household wiring is made of single-core copper wire and has a certain degree of rigidity. Automotive wiring harnesses, on the other hand, are made of multi-core copper wire, some of which are as thin as hair. Several or even dozens of soft copper wires are wrapped in plastic insulating tubes (polyvinyl chloride), making them more flexible. Automotive wiring harnesses require continuity testing.

[0004] There is an existing method (CN202111659115.8) for efficiently detecting the continuity of automotive wiring harnesses. This method involves providing a testing workbench, connecting the automotive wiring harness using a plug-in module, outputting voltage from the power supply output terminal, receiving feedback from the power supply feedback terminal, and finally displaying the sampled value for comparison. This method efficiently detects the continuity and product quality of the wiring harness. However, it has shortcomings: the existing equipment has poor testing efficiency, poor testing adaptability, and poor shaft adaptability, making it inconvenient to use. Therefore, a multi-station parallel intelligent testing device for the continuity of automotive wiring harnesses is needed to solve the above problems. Utility Model Content
