摘要：The mechanical performance of the cable is directly related to the electrical performance of the cable, and even affects the safety, reliability and durability of the whole charging process. Electric vehicle charging cable is different from the traditional wire and cable, which has higher requirements for the mechanical properties of the cable. In this paper, the tension test is carried out on the insulation or sheath of the cable. By observing the phenomenon of "slipping" and "end breaking" in the process of the test, the structure of the flat push collet is optimized. It can be seen from the comparative test analysis that the improved chuck mechanism has a great effect on improving the test accuracy and reliability.
