It can only perform a single high-voltage test. However, high-voltage testing is only one of the tests for automotive wiring harnesses. Tensile strength testing, bending strength testing, and torsional strength testing are also standards for verifying whether automotive wiring harnesses meet the standards. However, the automotive wiring harness high-voltage test bench can only perform a single high-voltage test. When performing other tests, it is necessary to transfer the test to other test benches, which has the disadvantage of limited functionality. Utility Model Content

The two dual-axis cylinders drive the two corresponding L-shaped clamps 6 to move to the opposite position to fix the front and rear ends of the automotive wiring harness.

[0046] Then, the second servo motor 15 is started, which drives the bidirectional bolt rod 19 to rotate.
