[0021] Embodiment 1:

[0022] As shown in the accompanying drawings, Figure 1 , 2The embodiment shown in figures 1, 2, 3, 4, 5 provides a cable with a sealed moisture-proof cable end, which comprises a cable body 1, a connecting ring 2 is sleeved on one end of the cable body 1, a sealing sleeve 3 is arranged at one end of the connecting ring 2, a fixing ring 4 is jointly arranged at the connecting position of the connecting ring 2 and the sealing sleeve 3, auxiliary rotating structures are arranged on both sides of the outer wall of the fixing ring 4, the auxiliary rotating structures comprise a breaking plate 5, a receiving groove 6 is formed in the outer wall of the fixing ring 4, the breaking plate 5 is arranged in the receiving groove 6, a rectangular block 7 is fixedly arranged at one end of the breaking plate 5, shaft pins 8 are arranged at both ends of the rectangular block 7, the rectangular block 7 is rotatably connected in the receiving groove 6 through the shaft pins 8, a movable cavity 9 is formed in the breaking plate 5, an extension plate 10 is slidably arranged in the movable cavity 9, an abutting plate 11 is arranged at one end of the extension plate 10, an extrusion plate 12 is arranged at the other end of the extension plate 10 in the movable cavity 9, a return spring 13 is connected between the extrusion plate 12 and the movable cavity 9, outer threads are arranged on the surfaces of the connecting ring 2 and the sealing sleeve 3, inner threads are arranged on the inner wall of the fixing ring 4, the fixing ring 4 is threadedly connected with the connecting ring 2 and the sealing sleeve 3, two locking holes are formed in the inner wall of the receiving groove 6, two locking pins 21 are fixedly arranged on the outer wall of the abutting plate 11, and the locking pins 21 are matched with the locking hole structure.

[0023] Specifically, unlike the prior art, the structure is used for assisting the fixing ring 4 to threadedly rotate to disassemble and assemble the connecting ring 2 and the sealing sleeve 3, so that the fixing ring 4 is not too tightly connected and is difficult to disassemble due to corrosion. Specifically, the connecting ring 2 is sleeved on the outside of the cable body 1 to prevent moisture from entering the insulating layer 101 at the end of the cable body 1, and the sealing sleeve 3 is connected at one end of the connecting ring 2 to prevent moisture from entering the conductor 100.

[0024] After the connecting ring 2 and the sealing sleeve 3 are connected, the fixing ring 4 is threadedly connected with the connecting ring 2 and the sealing sleeve 3 by rotating the fixing ring 4, so as to ensure the stability of the connection between the connecting ring 2 and the sealing sleeve 3.

[0025] When the connecting ring 2 and the sealing sleeve 3 are disassembled for maintenance of the cable, and when the fixing ring 4 is too tightly connected or is difficult to disassemble due to corrosion, the operator uses the auxiliary rotating structure. Since the top position of the abutting plate extends out of the outside of the receiving groove 6, the operator can slide the abutting plate 11 to one side, so that the extension plate 10 drives the extrusion plate 12 to slide in the sliding cavity of the breaking plate 5, and the return spring 13 is extruded.

[0026] Since auxiliary rotation structures are provided on both sides of the outer wall of the fixed ring 4, the operator can easily rotate the fixed ring 4 by holding the two 90° rotating levers 5 and applying pressure to rotate it, thereby avoiding the fixed ring 4 being too tight or corroded and difficult to remove.

[0027] The lever plate 5 can be rotated back into the storage slot 6 and locked by the locking pin 21 and locking hole to prevent the lever plate 5 from falling out of the storage slot 6 for no reason.

[0029] Specifically, the cable body 1 is composed of a conductor 100, an insulation layer 101, an embedded layer 102, a filler layer 103, a braided layer 104, a waterproof layer 105, and a sheath layer 106.

[0030] The conductor 100 is used for the energization of the entire cable body 1. The insulation layer 101 provides protection and insulation for the conductor 100. The filling layer 103 between the embedded layer 102 and several insulation layers 101 can ensure the stability of the three sets of insulation layer 101 structures. The braided layer 104 is a metal braided layer 104, which improves the tensile strength of the cable. The waterproof layer 105 can prevent the cable body 1 from being affected by water. The sheath layer 106 is a rubber sheath layer 106, which effectively improves the service life of the cable.
