[0031] Furthermore, the clamping assembly 202 includes a connecting sleeve 202a sleeved on the cable body 100, and a clamping sleeve 202b arranged on the connecting sleeve 202a. The size of the connecting sleeve 202a is adapted to the first cable 101 and the second cable 102. The clamping sleeve 202b is coaxial with the connecting sleeve 202a. The size of the clamping sleeve 202b is slightly larger than the connecting sleeve 202a. The inner wall of the clamping sleeve 202b is provided with a slope for clamping the clamping claw 201b, and the slope of the slope of the clamping sleeve 202b is greater than the slope of the clamping claw 201b.

[0032] Further, a slide groove 202c is provided on the tightening sleeve 202b, a spring block 202d is provided in the slide groove 202c, a receiving groove 202e is provided in the tightening sleeve 202b, and a rotating ring 202f is sleeved on the tightening sleeve 202b.

[0037] Specifically, the groove 301a is an annular groove, the first sealing ring 301b is arranged in the groove 301a, the first sealing ring 301b partially extends out of the groove 301a, and the tightening head 301c at the top of the clamping claw 201b tightens the first sealing ring 301b when the connecting sleeve 202a is fixed, so that the first sealing ring 301b is deformed and fills the gap.

[0038] Furthermore, the first sealing ring 301b is interference fit with the groove 301a, the first sealing ring 301b corresponds to the position of the tightening head 301c, the setting position of the first sealing ring 301b does not affect the normal activity of the connecting sleeve 202a, and the first sealing ring 301b is in contact with the surface of the cable body 100 in a normal state.

[0039] The rest of the structure is the same as that of Example 1.

[0040] Operation process: When the connecting sleeve 202a is installed, as the clamping sleeve 202b presses down the clamping claw 201b, the connecting sleeve 202a gradually approaches the top of the clamping claw 201b, and the tightening head 301c gradually squeezes the first sealing ring 301b and deforms it. After the first sealing ring 301b is deformed, it fills the gap between the connecting sleeve 202a and the cable body 100.

[0047] Operation process: When the two clamping sleeves 202b are fixed on the clamping claws 201b during use, the two sealing sleeves 302a approach each other from the outside of the terminal sleeve 201a until they fit together. At this time, the second sealing ring 302c is pressed into the sealing groove 302b, thereby closing the connection between the two sealing sleeves 302a, protecting and sealing the terminal sleeve 201a inside to prevent water from entering. After the two sealing sleeves 302a fit together, the claws 302e are clamped in the corresponding fixing grooves 302f to connect the two sealing sleeves 302a to prevent them from detaching to both sides. When disassembling, rotate one sealing sleeve 302a to disengage each claw 302e from the fixing groove 302f to unlock it.
