[0021] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0022] 1. A support and traction docking mechanism is set up. Through the cooperation of the card slot and the card block, the semi-arc sleeve can be conveniently limited to the outside of the ring by using the connection block, which improves the convenience of splicing. The ring and the semi-arc sleeve support the arc cover together, making it easy to splice the two arc covers on the outside of the ring. The wire mesh is reinforced to prevent separation and ensure the stability of the splicing. The heat is transferred through the thermal conductive strip to facilitate heat dissipation. At the same time, the arc cover and the corrugated tube are filled with flame-retardant cotton to improve the flame retardant effect of the cable. Through the cooperation of the elastic rope, the ring and the semi-arc sleeve, the cable can be pulled to reset after being bent;

[0023] When two cables need to be connected, the two half-arc sleeves at the adjacent ends of the two conductors are removed from the rings. Then, by utilizing the telescopic characteristics of the elastic rope, the half-arc sleeves can be pulled to move, so that the half-arc sleeve on one conductor is clamped to the outside of the ring of the other conductor, and the half-arc sleeve on the other conductor is clamped to the outside of the ring on one conductor, forcing the elastic ropes on the two conductors to cross and pull each other, pulling the two cables together, thereby improving the convenience of connection.

[0024] 2. A connection reinforcement mechanism is provided. Through the cooperation of the sleeve and the buckle, it is convenient to sleeve on the outside of the outer bushing. Then, through the cooperation of the active gear ring and the driven gear ring, it is convenient to rotate the rotating ring to push the shaft sleeve outside the buckle ring to rotate together, thereby pushing the pin to rotate and descend, and embed into the positioning hole outside the fixed ring, fixing the position of the armored extension tube, sealing ring and sleeve;

[0025] During splicing, the sealing ring and sleeve at the other end of the armored extension tube are sleeved onto another cable and fixed by a rotating ring, which improves the convenience and stability of the connection between the two cables. In addition, due to the bending and extension characteristics of the armored extension tube, the cable can be bent conveniently, which improves adaptability. At the same time, the inner wall of the sealing ring fits tightly with the outer side of the outer sleeve to ensure sealing. In addition, when splitting the cable, the cable can be peeled according to the position of the fixing ring to expose the sleeve and the semi-arc sleeve, which is convenient for subsequent connection and improves adaptability.

[0026] 3. A heat conduction and filling mechanism is set up. The insulation tape and rubber sleeve are combined to improve the insulation effect of the cable and prevent leakage. The groove, arc-shaped support plate and rubber tube are combined to support the rubber sleeve, leaving a gap between the rubber sleeve and the heat-conducting layer to facilitate the subsequent diffusion of heat. At the same time, because the arc-shaped support plate and rubber tube are elastic, they ensure the support effect while facilitating the bending of the cable.

[0027] The combination of the thermal conductive layer and the carbon fiber facilitates the transfer of heat generated by the conductor, allowing the heat to diffuse and transfer in the gap between the rubber sleeve and the thermal conductive layer, thereby improving the heat dispersion effect, preventing heat concentration, and reducing the temperature inside the cable. At the same time, the flame retardant layer increases the flame retardant effect of the cable, and the flame retardant layer is reinforced with reinforcing ribs and reinforcing nets to increase the strength of the flame retardant layer and prevent breakage.

[0028] In summary, through the cooperation of the support and traction docking mechanism and the connection reinforcement mechanism, with the use of auxiliary tools, the two cables can be spliced, aligned, and fixed together. At the same time, the two connections are extensible and bendable, which is convenient for bending and ensures the stability of the connection. In addition, the inside of the cable is filled through the heat conduction and filling mechanism to improve the flame retardancy and heat dissipation of the cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] An outer sleeve 401 is sleeved on the outside of the wire mesh 312, and a fixing ring 402 is equidistantly fixed on the outside of the outer sleeve 401.

The outer side of the rotating ring 411 is evenly provided with anti-slip grooves, and the active gear ring 412 and the driven gear ring 410 are meshed with each other.

[0053] The inner liner 2 is provided with a heat conduction and filling mechanism 5, which includes an insulating tape 501, a heat conduction layer 502, a rubber sleeve 503, an arc-shaped support plate 504, a rubber tube 505, a groove 506, a carbon fiber strip 507, a flame retardant layer 508, a reinforcing rib 509 and a reinforcing mesh 510;

[0054] An insulating tape 501 is wound around the outside of the conductor 1, and a heat-conducting layer 502 is sleeved on the outside of the insulating tape 501. A rubber sleeve 503 is sleeved on the outside of the heat-conducting layer 502. Arc-shaped support plates 504 are equidistantly clamped on the inner wall of the rubber sleeve 503, and a rubber tube 505 is filled between the arc-shaped support plates 504 and the rubber sleeve 503. Grooves 506 are opened on the outside of the heat-conducting layer 502 at positions corresponding to the inner sides of the arc-shaped support plates 504, and carbon fiber strips 507 are clamped between two adjacent grooves 506 on the outside of the heat-conducting layer 502. In order to improve the heat conduction effect, the insulating tape 501 is spirally wound around the outside of the conductor 1, and the inside of the heat-conducting layer 502 is filled with thermal grease. One end of the arc-shaped support plate 504 is embedded in the groove 506.

[0055] The outer side of the rubber sleeve 503 is sleeved with a flame retardant layer 508, and the inside of the flame retardant layer 508 is equidistantly clamped with reinforcing ribs 509, and the outer side of the flame retardant layer 508 is sleeved with a reinforcing net 510. In order to ensure the supporting effect of the arc-shaped support plate 504, the outer side of the rubber tube 505 is in contact with the inner wall of the arc-shaped support plate 504, and the inside of the rubber tube 505 is filled with filling cotton. The flame retardant layer 508 is filled with chlorinated paraffin and chlorinated polyethylene, and the outer side of the reinforcing net 510 is in contact with the inner wall of the inner sleeve 2.

[0056] The working principle and usage process of the present invention are as follows: First, the conductor 1 is wrapped with the insulating tape 501 and cooperates with the rubber sleeve 503 to improve the insulation effect of the cable and prevent leakage. Then, the arc-shaped support plate 504 is limited by the cooperation of the groove 506, so that the arc-shaped support plate 504 can support the rubber sleeve 503, leaving a gap between the rubber sleeve 503 and the heat-conducting layer 502 to facilitate subsequent heat diffusion. At the same time, because the arc-shaped support plate 504 and the rubber tube 505 are elastic, the support effect is ensured while facilitating the bending of the cable.

[0057] Next, the heat-conducting layer 502 is used to facilitate the transfer of heat generated by the conductor 1, so that the heat is diffused in the gap between the rubber sleeve 503 and the heat-conducting layer 502, thereby reducing the temperature. The carbon fiber strips 507 are used to transfer the heat laterally, further improving the heat dispersion effect, preventing heat from being concentrated, and reducing the temperature inside the cable. At the same time, the flame-retardant layer 508 is used to increase the flame-retardant effect of the cable. The reinforcing ribs 509 and the reinforcing mesh 510 are used to reinforce the flame-retardant layer 508, thereby increasing its strength and preventing breakage.

[0058] Then, by cooperating with the clamping block 306 and the clamping slot 308, the connecting block 304 is conveniently limited to the inside of the embedded groove 307 on the outside of the ring 302, so that the connecting block 304 and the semi-arc sleeve 303 are spliced ​​on the outside of the corrugated tube 301, which facilitates the cooperation between the ring 302 and the semi-arc sleeve 303 to support the arc cover 309, and facilitates the splicing of the two arc covers 309 on the outside of the ring 302. At the same time, the two arc covers 309 are reinforced by the wire mesh 312 to prevent separation and ensure the stability of the splicing. At the same time, the arc cover 309 and the corrugated tube 301 are filled with flame retardant cotton 310 to further improve the flame retardant effect of the cable. Then, by the telescopic characteristics of the elastic rope 305, and cooperating with the ring 302 and the semi-arc sleeve 303, the cable is pulled back to its original position after being bent.

[0059] Next, when two cables are to be butted together, the two semi-arc sleeves 303 at the adjacent ends of the two conductors 1 are removed from the ferrules 302. The elastic ropes 305 are then used to facilitate the pulling and moving of the semi-arc sleeves 303 so that the semi-arc sleeve 303 on one conductor 1 is clamped onto the outer side of the ferrule 302 of the other conductor 1, while the semi-arc sleeve 303 on the other conductor 1 is clamped onto the outer side of the ferrule 302 of the one conductor 1. The elastic ropes 305 on the two conductors 1 are intertwined and pulled together, pulling the two cables for splicing and forcing the two cables to fit together, thus completing the preliminary butt connection of the two cables.

[0060] Finally, during the docking process, the sealing rings 404 and sleeves 406 at both ends of the armored extension tube 405 are respectively sleeved on the outside of the two cables, and the buckle 407 is sleeved on the outside of the fixed ring 402. Then, the rotating ring 411 is rotated to drive the active gear ring 412 to rotate, and through the cooperation of the driven gear ring 410, the shaft sleeve 408 is pushed to rotate, forcing the pin 409 to rotate and descend, and embed into the positioning hole 403 outside the fixed ring 402, so as to position and reinforce the two cables, thereby improving the stability of the connection between the two cables. In addition, due to the bending and extension characteristics of the armored extension tube 405, it is convenient for the cable to be bent, thereby improving adaptability. At the same time, the inner wall of the sealing ring 404 is tightly fitted with the outer side of the outer sleeve 401 to ensure sealing. In addition, when splitting the cable, according to the position of the fixed ring 402, the skin is peeled off to facilitate exposing the ring 302 and the semi-arc sleeve 303, which is convenient for subsequent connection and improves adaptability.

[0061] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
