Description

Technical Field

[0001] The utility model relates to the technical field of inspection jigs, in particular to an inspection jig for detecting automobile wiring harness circuits. Background Art

[0002] An automotive wiring harness is a circuit assembly consisting of copper wire terminals crimped onto electrical wires and cables, then covered with a plastic-molded insulator or metal casing. As automotive electrical features and functions continue to increase, the wiring harnesses connecting these components are becoming increasingly complex, making them a common source of vehicle failures. These failures can range from component failure to component corrosion, even leading to vehicle burns. To ensure the safety, reliability, and quality of wiring harnesses, rigorous and rapid inspection and screening are essential to promptly identify and eliminate substandard products such as poor contact (open circuits, momentary disconnections), poor insulation (short circuits), and assembly errors. A wiring harness is a group of metal wires and cables tied together to connect signals and power between carrying devices. It is a wiring component that connects various electrical devices in the automotive circuit. It is composed of an insulating sheath, terminal blocks, wires, and insulating wrapping materials. An inspection jig is needed to detect automotive wiring harness circuits. However, in actual use, automotive daytime running lights with similar structures still have many defects. For example, in the process of detecting whether the wiring harness is qualified, the terminal blocks and wiring ports of the wiring harness need to be frequently inserted and removed. Sometimes, the wiring harness cannot be inserted vertically or the force is unevenly applied, which makes the inside of the wiring port easily damaged, affecting subsequent wiring harness detection. Therefore, it is necessary to design an inspection jig for detecting automotive wiring harness circuits. Utility Model Content
