A third magnetic sheet 16 is fixedly provided on the inner wall of the chamber 15 on the side away from the plug 2. The end of the plug 2 is sleeved with a sealing sleeve 5 that is engaged with the outside of the outer insulating sleeve 7, and the third magnetic sheet 16 is sealed with the sealing sleeve 5.

Because the first magnetic sheet 10 and the third magnetic sheet 16 are attracted to each other, the chamber 15 is tightened, so that the chamber 15 is sealed at the position where the plug 2 is attached to the charging socket 4, the waterproof performance is good, and it has a certain suction force, and it is not easy to cause poor contact between the plug 2 and the charging socket 4 due to dragging the cable 1.

Since the damping of the surface of the first elastic expansion zone 17 that fits the second elastic expansion zone 18 and the outer ring surface of the second elastic expansion zone 18 is large, when the first elastic expansion zone 17 is stretched, the second elastic expansion zone 18 is also stretched to a certain extent, so that the conductive core 8 can be better inserted into the conductive core jack 13, thereby achieving the purpose of strengthening the contact and avoiding the phenomenon of poor contact when the plug 2 is docked with the charging socket 4.
