It includes a cable connector body, a protective shell is arranged on the outside of the cable connector body, and a buffer spring is fixedly connected between the inside of the protective shell and the cable connector body. The shock-absorbing cable connector for high-voltage cables is provided with a buffer spring, shock-absorbing particles, a limit sleeve and a limit sleeve rod. When the protective shell is impacted by external force, the protective shell will squeeze the buffer spring, and the buffer spring will buffer the protective shell according to its own elasticity. Buffering the protective shell can reduce the impact force on the cable connector body and the high-voltage cable. The shock-absorbing particles can further reduce the impact force on the cable connector body and the high-voltage cable. When the external force disappears, the buffer spring drives the protective shell to rebound and restore. It solves the problem that the high-voltage cable connector does not have an effective shock-absorbing function and the high-voltage cable is easily damaged during use.
