The two ends of the connecting body 1 are respectively provided with a fixed end and a snap-on end. The connecting body 1 is provided with a fixing structure at the fixed end. After the cable passes through the connecting body 1, the fixing structure can fasten the cable. The connecting body 1 is provided with a snap-on structure at the snap-on end. The snap-on structure can snap-on and fix the cable connector to the distribution box. This new snap-on cable connector omits the nut fastening operation, saves materials, and improves the installation and fixing efficiency of the cable connector.

[0037] Specifically, the fixing structure includes a fixing tube 21, one end of which is fixedly connected to the connecting body 1, a deformable clamping piece 22 is provided on the top of the other end of the fixing tube 21, an external thread is provided on the outer side of the fixing tube 21 body, and the fixing tube 21 is provided with a locking nut 23 through the external thread, and a locking hole 24 with a gradually decreasing inner diameter is provided at one end of the locking nut 23, and the locking nut 23 is screwed into the fixing tube 21 through one end of the fixing tube 21 provided with the clamping piece 22. During the movement of the locking nut 23, the locking hole 24 compresses the clamping piece 22 to deform to achieve the tightening of the cable.

[0038] A waterproof ring 25 is provided inside the fixing tube 21 . The waterproof ring 25 is an elastic waterproof ring 25 , which can be deformed under a force and has a highly effective waterproof effect.

[0039] Specifically, the clamping structure includes a clamping tube 31, one end of which is connected to the connection body 1, and a plurality of elastic clamping plates 32 are arranged around the outer side of the other end of the clamping tube 31, and the outer diameter of the clamping plate 32 is smaller than the inner diameter. Since the outer diameter of the elastic clamping plate 32 is smaller than the inner diameter, the clamping plate 32 can be deformed to easily enter the cable hole. After the clamping tube 31 enters the cable hole, the clamping plate 32 is reset to realize the snap connection. This method of clamping by using the elastically deformable clamping plate 32 with a gradually increasing inner diameter is efficient in installation and simple in operation.

[0040] Preferably, the clamping tube 31 is provided with a clamping groove 33 for accommodating the clamping plate 32 at the lower part of the clamping plate 32 , the outer end surface of the clamping plate 32 is fixedly connected to the clamping groove 33 , and the clamping plate 32 is arranged in a tilted shape.

[0041] For distribution box bodies of different thicknesses, the outer side of the clamping tube 31 body is provided with an external thread, and the inner side of the connecting body 1 is provided with an internal thread matching the external thread. The clamping tube 31 and the connecting body 1 are adjustably connected through the thread.

[0042] A shock absorbing pad 34 is sleeved on the clamping tube 31 . The shock absorbing pad 34 is located inside the clamping plate 32 . A spring pad 37 is provided inside the shock absorbing pad 34 .

[0043] The shock-absorbing pad 34 and the spring pad 37 improve the stability of the cable connector, and the cable connector has the functions of being waterproof, dustproof and shockproof.

[0044] In addition, a plurality of limiting columns 35 are protruded on the inner side of the shock absorbing pad 34 , and a limiting groove 36 is provided on the clamping tube 31 . The limiting columns 35 are clamped into the limiting groove 36 to limit the shock absorbing pad 34 .

[0045] In practical application:

[0046] A fixing structure and a clamping structure are respectively provided at both ends of the clamping cable connector connection body 1. After the cable passes through the connection body 1, the fixing structure can tighten the cable. The clamping structure can directly press the cable connector to the distribution box body, omitting the nut tightening operation, saving materials, and improving the installation and fixing efficiency of the cable connector.

[0047] The clamping structure includes a clamping tube 31 and a plurality of elastic clamping plates 32. The outer diameter of the clamping plate 32 is smaller than the inner diameter. Thus, the cable connector is pressed into the cable hole from the outer side of the clamping tube 31. Since the outer diameter of the elastic clamping plate 32 is smaller than the inner diameter, the clamping plate 32 can be deformed and easily enter the cable hole. After the clamping tube 31 enters the cable hole, the clamping plate 32 is reset to realize the snap connection. This method of clamping using the elastically deformable clamping plate 32 with a gradually increasing inner diameter is efficient in installation and simple in operation.

[0048] The clamping tube 31 is provided with a clamping groove 33 for accommodating the clamping plate 32 at the lower part of the clamping plate 32. The clamping plate 32 is plate-shaped, and the outer end face of the clamping plate 32 is fixedly connected to the clamping groove 33, and the other side faces of the clamping plate 32 are non-contacting with the clamping groove 33. The clamping plate 32 is tilted, and a clamping groove 33 is provided below the clamping plate 32. The tilted clamping plate 32 has an elastic variation range. This structure is simple to manufacture and has strong buckle stability.

[0049] The clamping tube 31 is connected to the connecting body 1 in an adjustable threaded manner. Rotating the clamping tube 31 can adjust the distance between the clamping plate 32 and the connecting body 1. By adjusting the distance between the clamping plate 32 and the connecting body 1, distribution box bodies of different thicknesses can be clamped, thereby improving the stability and adaptability of the cable connector clamping.

[0050] A shock absorbing pad 34 is sleeved on the clamping tube 31 and is located on the inner side of the clamping plate 32 . A plurality of limiting columns 35 are protruded on the inner side of the shock absorbing pad 34 . A limiting groove 36 is provided on the clamping tube 31 . The limiting columns 35 can be inserted into the limiting groove 36 to limit the shock absorbing pad 34 .

[0051] A spring pad 37 is provided inside the shock-absorbing pad 34 . The spring pad 37 has elastic deformation, which improves the stability of the cable connector installation.
