[0031] The auxiliary seal 45 includes a rotating seat 451 and an auxiliary support rod 452, wherein the rotating seat 451 is rotatably arranged on the sealing support rod 44, the output end of the rotating seat 451 is rotatably arranged with the auxiliary support rod 452, and an elastic sealing pad 46 is wrapped between the plurality of the auxiliary support rods 452, and the elastic sealing pad 46 bypasses the rotating seat 451, wraps around the plurality of the sealing support rods 44 and is fixedly connected to the conical ring 42;

[0032] That is to say, the plurality of auxiliary support rods 452 and the elastic sealing pad 46 can form a sealing ring, and the size of the sealing ring can be changed by driving the plurality of sealing support rods 44 to rotate and slide, and the plurality of auxiliary support rods 452 can maintain a gathered state under the elastic force of the elastic sealing pad 46, that is, when the auxiliary support rod 452 is attached to the cable, the elastic sealing pad 46 can wrap around the cable to seal the cable, and through the rotation of the rotating seat 451, when the sealing support rod 44 rotates, the auxiliary support rod 452 can always be attached to the cable surface through the rotation of the rotating seat 451 and its own rotation, that is, effective sealing is achieved for cables of different specifications;

[0036] In this embodiment, Figure 6 A connecting groove is provided on the connecting member 1 31 , a metal guide rod 311 is fixedly arranged in the connecting groove, and a metal guide ring 321 is fixedly arranged on the connecting member 2 32 , and the metal guide ring 321 can be inserted into the connecting groove and electrically connected to the metal guide rod 311 .

[0037] In this embodiment, Figure 7 The core clamping member 33 includes a clamping ring 331, a clamping rod 332, a driving ring 333 and a second swivel ring 334, wherein the two clamping rings 331 are respectively fixedly arranged on the first connecting member 31 and the second connecting member 32, a plurality of clamping rods 332 are arranged in a circular sliding manner inside the clamping ring 331, a sliding rod 1 335 is fixedly arranged on the clamping rod 332, a driving ring 333 is rotatably arranged on the outer side of the clamping ring 331, a plurality of arc grooves 1 336 are opened on the driving ring 333, the sliding rod 1 335 slides along the arc groove 1 336, and a swivel ring 2 334 is slidably arranged on the driving ring 333;

[0038] It should be noted that the clamping ring 331 and the clamping rod 332 are both metal conductors, and the two clamping rings 331 are electrically connected to the metal guide ring 321 and the metal guide rod 311 respectively;

[0039] The driving ring 333 is fixed with a plurality of protrusions, and the second rotating ring 334 is provided with a plurality of grooves, and the protrusions are inserted into the grooves and slide along the grooves;

[0040] The first connecting member 31 and the second connecting member 32 are both rotatably provided with ratchets 34, and the ratchet 34 is fixedly provided with a gear ring 1 341;

[0041] A second gear ring 337 is fixedly disposed on one side of the second rotating ring 334 close to the ratchet wheel 34 , and the first gear ring 341 and the second gear ring 337 can mesh with each other.

[0042] When implementing, it is only necessary to insert the wire core into the clamping ring 331 and then rotate the swivel ring 2 334 so that the driving ring 333 drives the multiple clamping rods 332 to slide and clamp the wire core. Then, the connecting piece 1 31 is connected to the connecting piece 2 32 to complete the connection of the two wire cores, making the connection of the wire core more convenient and quick. Moreover, through the design of the ratchet 34, the swivel ring 2 334 can only rotate in one direction when it is in contact with the ratchet 34, that is, the clamping rod 332 will not loosen after clamping the wire core. When the wire core needs to be loosened, it is only necessary to drive the swivel ring 2 334 to slide and disengage from the ratchet 34 to rotate the swivel ring 2 334 in the opposite direction, that is, to loosen the wire core. Moreover, through the design of the gear ring 1 341 and the gear ring 2 337, no matter how the swivel ring 2 334 is rotated, it can be engaged with the ratchet 34, thereby making the work of fixing the wire core on the wire core connector 3 more convenient and quick.

[0045] During implementation, when the snap ring 11 is inserted into the sealing groove 21, the snap ring 11 can drive the multiple blocks 22 to slide and squeeze the spring 24. When the snap ring 11 is out of the engagement range of the block 22, the block 22 slides under the action of the spring 24 to clamp the snap ring 11, thereby realizing the engagement between the shell 1 and the shell 2 2. When it is necessary to separate the shell 1 from the shell 2 2, it is only necessary to rotate the rotating ring 3 23 so that the block 22 slides under the action of the slide bar 221 and the arc groove 2 231, that is, the block 22 no longer engages the snap ring 11, and then the shell 1 and the shell 2 2 are separated, thereby further making the connection of the cables more convenient and quick.

[0046] In summary, when the present invention is implemented, the cable seal 4 and the sealing cover 5 are designed so that the connecting ends of the cable and the outer shell 1 and the outer shell 2 can be sealed to prevent water from penetrating from between the cable and the outer shell 1 and the outer shell 2 to the inside of the outer shell 1 and the outer shell 2 to cause damage to the cable, and the sealing size of the cable seal 4 can be adjusted, that is, cables of any specifications can be effectively sealed. In addition, the design of the wire core clamp 33 makes it only necessary to put the wire core into the clamp ring 331 when connecting, and then rotate the swivel 334 to connect the wire core with the connector 1 31 and the connector 2 32, and then connect the connector 1 31 with the connector 2 32 to complete the connection of the two sections of the cable core, thereby making the connection of the wire core more convenient and quick, and the outer shell 1 and the outer shell 2 are connected by a clamping method, which further makes the connection of the cable more convenient and quick, and a completely sealed space can be formed between the connected outer shell 1, the outer shell 2 and the cable, further improving its waterproofness and protection of the cable.
