Description

Technical Field

[0001] The utility model relates to the technical field of cable testing, in particular to a cable tensile testing device. Background Art

[0002] Tensile testing machines are often used to test the mechanical properties of wires and cables. Usually, samples such as wires and cables or cable sheaths are clamped by the clamp of the tensile testing machine, and then the clamp is moved to apply tension to the sample. The force on the sample is detected in real time by the tensile sensor, thereby simulating the mechanical stress it is subjected to and testing the tensile strength and breaking force of the wires and cables.

However, when clamping the cable, when the pulling force on the cable becomes greater and greater, it may cause the clamped end of the cable to fall off or loosen, which may affect the data of the cable tensile test and reduce the accuracy of the test data.
