[0010] Furthermore, the electrical appliance end of the cable is also sleeved with a protective tube, one end of the protective tube extends into the interior of the pressure-proof shell, and the other end of the protective tube is connected to the cable.

[0011] The utility model further prevents water from entering the connection between the terminal and the electrical connector by arranging a protective tube, thereby further improving the waterproof performance.

[0012] Furthermore, the protective tube is a corrugated tube.

[0013] The utility model can ensure that the protective tube is bent according to the wiring conditions of the whole vehicle by using the corrugated tube as the protective tube, thereby preventing the protective tube from being damaged during wiring.

[0014] Furthermore, the protective tube and the cable are connected by binding with a wear-resistant tape.
