A protective inner shell 300 is arranged on the outer side of the cable body 200, and a protective outer shell 100 is arranged on the outer side of the protective inner shell 300. The protective inner shell 300 is of a two-piece structure. The arranged protective outer shell 100 and protective inner shell 300 can form two protective layers at the connection of the cable body 200, thus ensuring the sealing effect at the connection of the cable body 200. The material of the arranged protective inner shell 300 can be selected as rubber material. Arc-shaped clamping grooves for clamping the cable body 200 are opened at both ends of the protective inner shell 300. A central connecting sleeve 310 is fixed at the center of the inner wall bottom end of the bottom protective inner shell 300. The opposite sides of the two cable bodies 200 are clamped with the outer wall of the central connecting sleeve 310. The protective outer shell 100 is of a two-piece structure. The protective outer shell 100 is clamped on the outer wall of the protective inner shell 300. Positioning insertion rods 321 are fixed at the side ends of the outer wall of the protective inner shell 300. A plurality of positioning insertion rods 321 are uniformly arranged in an annular array. Annular clamping blocks 110 are fixed at the positions on the inner wall of the protective outer shell 100 corresponding to both sides of the outer wall of the cable body 200. Annular clamping grooves 301 are opened at the positions on the outer wall of the cable body 200 corresponding to the annular clamping blocks 110. The outer walls of the annular clamping blocks 110 are connected with the inner walls of the annular clamping grooves 301. Specifically, when the protective outer shell 100 is closed, the annular clamping blocks 110 can be inserted into the annular clamping grooves 301 opened at the corresponding positions on the outer wall of the protective inner shell 300, so as to press and fix the protective inner shell 300;

[0027] Positioning slots are opened at the positions on the inner wall of the protective outer shell 100 corresponding to the positioning insertion rods 321. The outer walls of the positioning insertion rods 321 are connected with the inner walls of the positioning slots. The opened positioning slots and the fixed positioning insertion rods 321 are for clamping the inner wall of the protective outer shell 100 and the outer wall of the protective inner shell 300. At the same time, they can cooperate with the annular clamping blocks 110 to position the center of the outer wall of the protective inner shell 300. Buffer rubber pads 320 are also arranged at the side ends of the outer wall of the cable body 200 corresponding to the inner wall of the protective outer shell 100. The ends of the buffer rubber pads 320 far from the cable body 200 are abutted against the side ends of the inner wall of the protective outer shell 100. Springs 322 are arranged on both sides of the buffer rubber pads 320. Both ends of the springs 322 are abutted against the opposite outer walls of the protective outer shell 100 and the cable body 200. The material of the arranged buffer rubber pads 320 can be selected as rubber layer. The arranged buffer rubber pads 320 can cooperate with the springs 322 to buffer and weaken the impact force exerted on the protective outer shell 100 from the outside, so as to avoid the loosening of the contact points of the cable body 200 due to external impact;

[0028] Sealing connection components are provided on both sides of the outer wall of the protective housing 100. The sealing connection components include port sealing plates 400. An arc-shaped groove matching the cable main body 200 is provided at the bottom end of the outer wall of the port sealing plate 400. The outer wall of the port sealing plate 400 abuts against the outer wall of the cable main body 200 through the arc-shaped groove. Through holes are provided at both ends of the outer wall of the protective housing 100 at positions corresponding to the cable main body 200. The diameter of the provided through holes is larger than the diameter of the cable main body 200, so that a gap is left between the protective housing 100 and the cable main body 200. Sealing ring gaskets 420 for sealing the gap between both ends of the protective housing 100 and the cable main body 200 are connected to the outer wall of the port sealing plate 400 away from the arc-shaped groove. The provided port sealing plate 400 can be composed of four sections. When in use, the two port sealing plates 400 can be inserted into the gap at the joint of the through hole and the cable main body 200, so that the sealing ring gasket 420 can seal the through hole and the cable main body 200, keeping the inside of the protective housing 100 in a closed state and avoiding the influence of dew or rain in the external environment on the connection stability of the cable main body 200. Reinforcing rods 410 are fixed to the outer wall of the port sealing plate 400 away from the sealing ring gasket 420. The plurality of reinforcing rods 410 are uniformly arranged in an annular array. The reinforcing rods 410 are arranged outside the protective housing 100. Fixing plates 411 are fixed to the ends of the reinforcing rods 410 away from the port sealing plate 400. Adjacent two fixing plates 411 are fixed by locking bolts. Specifically, after the two port sealing plates 400 and the sealing ring gaskets 420 are aligned and inserted into both ends of the protective housing 100, the reinforcing rods 410 provided on both sides will be aligned, so that the two fixing plates 411 can also be aligned. Then the personnel can take out the screws and nuts to fix the two fixing plates 411, so that the port sealing plate 400 can be fixed outside the protective housing 100, and at the same time, the two protective housings 100 can be fixed.

[0029] The usage process of the present utility model is as follows: Those skilled in the art first dock and connect the connection ends of the two cable bodies 200 through the central connection sleeve 310 provided on the bottom protection inner shell 300, and the data between the cable bodies 200 is connected through a special cable connector.

Then, the two protection outer shells 100 are taken out and the two protection outer shells 100 are vertically aligned and clamped on the outer wall of the protection inner shell 300, so that the annular clamping block 110 can be clamped in the opened annular clamping groove 301, and the positioning insertion rod 321 will be inserted into the positioning slot, so that the protection outer shell 100 can clamp the cable body 200. One end of the provided buffer rubber pad 320 and the spring 322 can be optionally fixed on the inner wall of the protection outer shell 100 or the outer wall of the cable body 200. In this way, after the protection outer shell 100 is clamped on the outer wall of the protection inner shell 300, the other ends of the provided buffer rubber pad 320 and the spring 322 will abut against the inner wall of the corresponding protection outer shell 100 or the outer wall of the cable body 200, so as to buffer and weaken the vibration and impact applied by the external environment to the protection outer shell 100, thereby improving the stability of the connection of the cable body 200;

[0030] After completion, the operator can take out the port sealing plate 400, and then insert the end of the port sealing plate 400 fixed with the sealing ring gasket 420 into the outer wall of the cable body 200, so that the sealing ring gasket 420 can seal the gap between the cable body 200 and the through hole. The upper and lower port sealing plates 400 will be aligned in the through hole, so as to seal the entire gap. When the port sealing plate 400 is placed, the two reinforcing rods 410 and the fixing plate 411 are aligned. Then, the screws and nuts can be taken out to lock and fix the two fixing plates 411, so that the port sealing plate 400 can be fixed on both sides of the protection outer shell 100, and at the same time, the protection outer shell 100 can be fixed, so that the protection outer shell 100 can ensure the fixing effect on the protection inner shell 300.
