[0015] Compared with the prior art, the utility model provides a new energy vehicle anti-stretching and anti-bending cable, which has the following beneficial effects:

[0016] 1. This kind of tensile and bending resistant cable for new energy vehicles ensures that the second core can be stretched by winding and squeezing the second core inside the connecting cover. When the cable is stretched, the second core is stretched by the force, and at the same time, the movable block follows the second core to leave the inner wall of the connecting cover, ensuring that the cable as a whole meets the tensile and bending resistance conditions.
