[0002] In power systems, cables are essential for transmitting electrical energy. Their continuity and stability are crucial to the normal operation of the entire system. They also play a key role in cable maintenance. When a cable fault occurs somewhere, maintenance personnel can isolate the faulty section by installing intermediate connectors on both sides of the fault point for repair.

[0003] A Chinese patent with patent publication number CN205231656U discloses a cable connector, including a main body, a locking nut and a fixing nut. The locking nut is threadedly connected to one end of the main body, and the fixing nut is threadedly connected to the other end of the main body. The end of the main body connected to the fixing nut is set as a plug-in end, and a groove is opened on the outer wall of the plug-in end along its axial direction. A brake block is provided in the groove for cooperating with the box to prevent the main body from rotating.

[0004] In the cable connector provided by this patent, a brake block structure is adopted to solve the problem of damage to the sealing gasket, but the cost of this structure is relatively high. Utility Model Content

[0006] The purpose of the utility model can be achieved through the following technical solutions: a cable waterproof connector, comprising a cable connector body, a cable connector nut and a cable connector nut, the cable connector body comprising a locking claw, a front threaded body, a flange body and a rear threaded body, the locking claw, front threaded body, flange body and rear threaded body are distributed in sequence, the front side of the cable connector nut is an arc body, the cable connector nut is internally provided with an internal thread, the internal thread is meshed and connected with the front threaded body, the locking claws are arranged in a circular array and a number of gaps are formed between the locking claws, a sealing ring is provided inside the locking claw, a number of protrusions are formed on the sealing ring, the protrusions extend into the gaps, a protective block is formed at the front end of the locking claw, the protective block is in contact with the outer side of the sealing ring, and the cable connector nut is meshed and connected with the rear threaded body.

[0007] In the above-mentioned cable waterproof connector, the diameter of the outer end portion of the locking claw is smaller than the diameter of the inner end portion.

[0008] In the above-mentioned cable waterproof connector, the diameter of the outer end portion of the sealing ring is smaller than the diameter of the inner end portion.

[0009] In the above-mentioned cable waterproof connector, the protrusion extends to the outer end surface of the sealing ring.

[0010] In the above-mentioned cable waterproof connector, the side surface of the locking claw inside the gap is an inclined surface.

[0011] In the above-mentioned cable waterproof connector, a sealing gasket is sleeved on the outside of the rear threaded body, the sealing gasket is fitted with one side of the flange body and is clamped by the flange body and the cable connector nut.

[0012] Compared with the prior art, the cable waterproof connector provided by the utility model has the following beneficial effects: 1. Through the structural setting that the outer end of the locking claw is smaller than the inner end, and through the connection structure that the convex body is provided on the sealing ring and the convex body is engaged with the gap, the sealing ring can be stably fixed inside the locking claw; 2. The side surfaces of the locking claw on both sides of the convex body and the gap are inclined surfaces, which reduce the squeezing effect of the locking claw on the sealing ring and reduce the risk of damage to the sealing ring; 3. Through the structural setting of the protective block on the outside of the locking claw, the sealing ring is further protected. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figures 1 to 4As shown, this embodiment includes a cable connector body 1, a cable connector nut 2, a cable connector nut 3, a sealing ring 4 and a sealing gasket 5. The cable connector body 1 is an integral body and the cable connector body 1 includes a locking claw 11, a front threaded body 12, a flange body 13 and a rear threaded body 14. The locking claw 11 and the rear threaded body 14 are the two end parts of the cable connector body 1. The front threaded body 12 is in contact with the inner side of the locking claw 11. The flange body 13 is located between the front threaded body 12 and the rear threaded body 14. An internal thread 22 is provided inside the cable connector nut 2. The cable connector nut 2 is sleeved on the outside of the locking claw 11 and the front threaded body 12 and is engaged with the front threaded body 12 through the internal thread 22. The front side of the cable connector nut 2 is Arc body 21, the locking claw 11 is located inside the arc body 21, the number of locking claws 11 is several and the locking claws 11 are arranged in a circular array, and a gap 111 is formed between each locking claw 11. The sealing ring 4 is arranged inside the locking claw 11, and the sealing ring 4 is formed with protrusions 41 with the same number as the gaps 111. The shape of the protrusion 41 is the same as the gap 111 and the protrusion 41 extends into the gap 111 to engage the sealing ring 4 with the locking claw 11. A protective block 112 is formed at the front end of the locking claw 11, and the protective block 112 is in contact with the outer side of the sealing ring 4. The cable joint nut 3 is engaged with the rear threaded body 14, and the sealing gasket 5 is in contact with one side of the flange body 13 and the sealing gasket 5 is clamped by the flange body 13 and the cable joint nut 3.
