Description

Technical Field

[0001] The utility model relates to the field technology of connecting line testing equipment, in particular to a tension testing device. Background Art

[0002] Terminal cables are designed to facilitate the connection of wires. They are essentially a piece of metal enclosed in insulating plastic, with holes at both ends for insertion. The number and spacing of wires can be freely selected, making connections easier and faster, significantly reducing the size of electronic products. They are widely used for data transmission between mobile components and motherboards, between PCBs, and in miniaturized electrical devices. After packaging, terminal cables undergo a tensile test. The terminal and cable ends of the cable are fixed separately, and the cable is pulled to test the tensile strength of the cable-terminal connection. This ensures the quality of assembled products and meets customer needs.

[0003] For the convenience of measurement, a connecting wire terminal tension test device is generally used for testing. For example, China Publication No. CN217542649U discloses a wiring harness terminal tension test device, which includes a base, a tension tester, and a cable fixing structure provided at the connection end of the tension tester; a terminal fixing structure, the terminal fixing structure including a fixing platform, a sliding groove provided on the fixing platform, and two clamping blocks slidably arranged in the sliding groove. The fixing platform is provided with a positioning assembly for fixing the position of the clamping blocks, and the base is provided with a traction assembly for driving the fixing platform to move. Although it can automatically adjust the distance between the clamping blocks by setting the clamping blocks close to or away from each other and using a drive motor to adapt to the tension test process of wire harnesses of different sizes and improve applicability, it is driven by a drive motor for clamping and the traction motor for pulling the wire harness for testing. In order to avoid the situation where the motor-driven traction force is too large or too small, it is necessary to select a tuning motor, which increases the design difficulty. In addition, the selection of motor drive requires power, the overall structure is relatively complex, and the cost is high.

[0004] Therefore, it is necessary to develop a new technology to solve the above problems. Utility Model Content
