[0002] A car is a vehicle that has its own power to drive and can be driven without tracks or electricity. In a broad sense, vehicles that are driven by their own mechanical energy are generally called cars; the car wiring harness is the network body of the car circuit. Without the wiring harness, there is no car circuit. The wiring harness refers to a component that is formed by crimping the terminals made of copper materials with wires and cables, and then plastic-pressing the insulators or adding metal shells on the outside to form a connecting circuit. From the perspective of function, the car wiring harness can be divided into two types: power lines that carry power to drive actuators and signal lines that transmit sensor input commands. After the wires are crimped inside the terminals, the connection strength between the terminals and the wires needs to be tested to avoid loose connections between the wires and terminals, which may cause the wires to detach from the terminals during use.

[0003] At present, the test of automobile wiring harness requires that one end of the wiring harness with a terminal passes through the test board, and the other end of the wiring harness is fixed, and then the fixed end of the wiring harness is pulled to complete the tension test of the automobile wiring harness. Due to the large number of automobile wiring harnesses, the fixation of multiple wiring harnesses increases the workload, thereby affecting the efficiency of the test. Utility Model Content
