Description

Technical Field

[0001] The utility model relates to the technical field of tension testing, and more particularly to an adjustable wire harness terminal tension tester. Background Art

[0002] After the harness terminal tensile tester is produced, it needs to be subjected to tensile testing to detect the connection strength between the cable and the terminal. The stability of the connection between the terminal and the cable is very important. If the cable is separated from the terminal, it will cause serious consequences.

[0003] The Chinese patent authorization number is CN202120052083.4, which discloses a wire harness terminal tensile tester, including a base, a tensile meter, a first fixing mechanism, a second fixing mechanism and a driving mechanism. The base is arranged in a long strip shape, and the tensile meter is installed and fixed on the base. One end of the first fixing mechanism is connected to the tensile meter, and the end of the first fixing mechanism away from the tensile meter is provided with a clamp for clamping the terminal. The second fixing mechanism is slidably arranged on the side of the first fixing mechanism away from the tensile meter. The second fixing mechanism is used to clamp and fix the wire harness connected to the terminal. The base is also provided with a guide groove arranged along the length direction of the wire harness. The driving mechanism is arranged on the base to drive the sliding seat to slide along the length direction of the guide groove.

[0004] Although the above-mentioned patent disclosure can realize the tensile test of the wiring harness terminal, the second fixing mechanism is directly moved by the driving device. Due to the limited size of the gear, the second fixing mechanism moves too far when the driving device is rotated, resulting in a large error between the detection data. Therefore, an adjustable wiring harness terminal tensile tester is proposed. Utility Model Content
