The wiring harness refers to the contact terminal (connector) punched from copper material, which is crimped with the wires and cables, and then plastic-pressed with an insulator or an additional metal shell, etc., to form a component connecting the circuit with the wiring harness. The automotive wiring harness mainly protects the automotive circuit, reduces wear and tear, and prevents water stains from entering. In order to ensure the sealing of the wiring harness and protect the wires, the wiring harness must be tested for water leakage during inspection.

[0003] After searching, the Chinese patent publication number is CN216012604U, which discloses a water leakage inspection device for automotive wiring harnesses. By setting up multiple clamping mechanisms, the equipment can simultaneously inspect multiple wiring harnesses, and with the cooperation of the weighing component, the quality of the wiring harness can be quickly inspected. It can also better find defective products mixed in the wiring harness, speed up the inspection progress of the wiring harness, and thus improve the work efficiency of the staff.

[0004] However, during use of the above patent, after immersion, when the surface of the wire harness is dried by a fan, the fan has a better drying effect on the wire harness close to the side, while water droplets still exist on the surface of the wire harness far away from the fan, affecting the subsequent weight measurement and thus the accuracy of the implementation.
