[0002] The wire harness tester is the most basic test instrument to ensure the quality and reliability of the wire harness. It can eliminate early failure products with faults such as short circuit, open circuit, wrong wiring, poor contact and instantaneous open circuit through the wire harness continuity test method, thereby improving product quality. Therefore, it is widely used in wire harness testing of household appliances, communication equipment, aircraft, automobiles and military instruments and equipment.

[0003] Among them, the wire harness tensile test equipment is a common test method used to determine the strength and stability of wire or cable harnesses under stress.

Through the setting of the first belt 21 and the second belt 22, the first belt 21 is provided in the connecting frame 2, and the first belt 21 drives the rotation of the second belt 22, so that the pulling assembly 20 moves up to test the wire harness. During the process, the limit plate 27 moves up to the outer wall of the fixed block 3, so that the pulling assembly 20 and the limit plate 27 work synchronously, reducing the energy consumption of the equipment.
