It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] Example: Figure 1 - Figure 5 As shown, a cable connector assembly includes a left housing 1 and a right housing 2 symmetrically arranged. A gap is left between the adjacent ends of the left housing 1 and the right housing 2 to minimize frictional resistance when the left housing 1 and the right housing 2 rotate relative to each other.

[0025] The left shell 1 and the right shell 2 are provided with annular sealing grooves 8 on the circumferential sides of the ends close to the gap, and the left shell 1 and the right shell 2 are rotatably connected through the annular sealing grooves 8 by a connecting structure between the adjacent ends, the connecting structure comprising a connecting ring 9 sleeved between the adjacent ends of the left shell 1 and the right shell 2, the connecting ring 9 being bent inward at both ends to form annular sealing members 10, the inner circle of the annular sealing members 10 extending into the annular sealing grooves 8 and being rotatably connected with the left shell 1 and the right shell 2 through the annular sealing grooves 8, so that the left shell 1 and the right shell 2 can rotate relative to each other while having strong sealing between them;

[0026] The left shell 1 and the right shell 2 are integrally formed with insulating plates 3 at the ends away from each other, one of the insulating plates 3 being fixedly connected with a left outer annular electrode 4, and the insulating plate 3 inside the left outer annular electrode 4 being fixedly connected with a left inner annular electrode 5;

[0027] The other insulating plate 3 is fixedly connected with a right outer annular electrode 6 whose outer wall is in contact with the inner wall of the left outer annular electrode 4, and the outer diameter of the left inner annular electrode 5 is smaller than the inner diameter of the right outer annular electrode 6, so as to avoid short circuit as much as possible after being electrified;

[0028] The insulating plate 3 inside the right outer annular electrode 6 is fixedly connected with a right electrode column 7, and the free end of the right electrode column 7 extends into the left inner annular electrode 5 and is in contact with the inner wall of the left inner annular electrode 5, so that the left outer annular electrode 4 and the right outer annular electrode 6, and the left inner annular electrode 5 and the right electrode column 7 are electrically connected;

[0029] The end of the left outer annular electrode 4 away from the insulating plate 3 is bent inward to form an inner flange, and the end of the right outer annular electrode 6 away from the insulating plate 3 is bent outward to form an outer flange, and the left outer annular electrode 4 and the right outer annular electrode 6 are limited by the inner flange and the outer flange, so as to avoid relative slipping between the left outer annular electrode 4 and the right outer annular electrode 6 when subjected to external tension, and to avoid the problem of open circuit and failure to supply power;

[0030] The two insulating plates 3 are each provided with a cable wiring assembly on the side away from each other, the cable wiring assembly comprising two groups of wiring terminals 11, the two groups of wiring terminals 11 being respectively mounted on the two insulating plates 3, and the two wiring terminals 11 in one group being electrically connected with the left outer annular electrode 4 and the left inner annular electrode 5 respectively, and the two wiring terminals 11 in the other group being electrically connected with the right outer annular electrode 6 and the right electrode column 7 respectively, so that the user can connect the live wire and the zero wire of two cables with the two groups of wiring terminals 11 respectively when in use, thereby realizing the connection of the cables;

[0031] The side of the insulation plate 3, on which the wiring terminal 11 is installed, is fixedly connected with a sealing sleeve 12, an outer thread is formed on the outer wall of the end of the sealing sleeve 12 away from the insulation plate 3, and the free end of the wiring terminal 11 is screwed with a sealing end cover 13 through the outer thread. After the wiring is completed, the sealing end cover 13 can be screwed on the sealing sleeve 12, so that a sealed cavity is formed in the sealing sleeve 12 and isolated from the outside, and the connection between the cable and the wiring terminal 11 is sealed and protected.

[0032] An wiring hole 14, which is aligned with the wiring terminal 11, is formed on the sealing end cover 13, the inner diameter of the wiring hole 14 is greater than the diameter of the cable, a rubber sealing ring is embedded in the wiring hole 14, and the rubber sealing ring can seal the connection between the cable and the wiring hole 14, further improving the sealing performance.

[0033] A limiting tube 15, which is aligned with the wiring hole 14, is fixedly connected to the inner wall of the insulation plate 3, the outer diameter of the limiting tube 15 gradually decreases from the end close to the sealing end cover 13 to the end away from the sealing end cover 13, and a plurality of annular expansion grooves 16 are formed on the free end of the limiting tube 15. Before the cable is connected to the wiring terminal 11, the cable is first passed through the limiting tube 15, the inner diameter of the smaller end of the limiting tube 15 is smaller than the outer diameter of the cable coating, and when the cable is passed through, the sidewall of the smaller end of the limiting tube 15 is extruded by the cable and expands along the expansion grooves 16 and tightly abuts against the cable coating to fix the cable. When the cable is subjected to external tension, the tension acts on the limiting tube 15, which can avoid the connection between the cable and the wiring terminal 11 being directly subjected to stress when the cable is subjected to external tension, thereby avoiding the problem that the cable and the wiring terminal 11 are easily separated.

[0034] It should be noted that, in use, two cables to be connected are passed through the limiting tube 15 from the wiring holes 14 formed in the two sealing end covers 13, the two cable ends are respectively welded and fixed to the two groups of wiring terminals 11, then the sealing end covers 13 are moved to be attached to the sealing sleeves 12, and the two sealing end covers 13 are respectively screwed on the two sealing sleeves 12, thereby completing the connection of the cables. Since the left outer annular electrode 4 and the right outer annular electrode 6, and the left inner annular electrode 5 and the right electrode column 7 can rotate relative to each other, when the cable is subjected to external torque, the left shell 1 and the right shell 2 can rotate relative to each other, thereby compensating for the torque acting on the cable, and avoiding the problem that the connection part between the cable and the connector is easily damaged by the torque.

[0035] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the present application. It should be noted that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
