The U-shaped slot not only uses too many compression springs, but also has too many U-shaped slots themselves, resulting in high manufacturing costs for the wiring structure. The wiring structure only has a waterproof function for the branch cable, but no clamping and fixing function. Therefore, a medium-voltage distribution network wiring structure is proposed to solve the above problems. Utility Model Content

[0008] Furthermore, the insert tube is connected to the junction box, and the mounting groove is located on the inner side wall of the insert tube.

[0009] Furthermore, the number of the mounting slots, the first springs and the clamping plates is not less than two, and the two clamping plates are positioned opposite to each other.

[0010] Furthermore, one end of the clamping plate close to the junction box is inclined, and the waterproof cylinder is threadedly connected to the insert cylinder.

[0011] Furthermore, the first waterproof ring is in contact with the outer wall of the junction box, and the main cable and the branch cable both pass through the second waterproof ring.

[0012] Furthermore, the fixed wiring board and the movable wiring board are both L-shaped, and the branch cable is located between the fixed wiring board and the movable wiring board.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] In the case implementation, the plug 211 is connected to the junction box 1, and the installation groove 212 is located on the inner wall of the plug 211. The number of the installation groove 212, the first spring 213 and the clamping plate 214 is not less than two. The two clamping plates 214 are positioned opposite to each other, and the end of the clamping plate 214 close to the junction box 1 is oblique. The main cable 3 and the branch cable 4 both pass through the plug 211. The main cable 3 and the branch cable 4 are both located between the two clamping plates 214. The main cable 3 and the branch cable 4 can be clamped and fixed by the two clamping plates 214, so it has a clamping and fixing function.

[0026] In the case implementation, the waterproof tube 221 is threadedly connected to the insert tube 211, the first waterproof ring 222 is in contact with the outer wall of the junction box 1, and the main cable 3 and the branch cable 4 both pass through the second waterproof ring 223. The first waterproof ring 222 and the second waterproof ring 223 can prevent water from entering the inner side of the insert tube 211, thus having a waterproof function.

[0027] In the case implementation, the fixed cable plate 501 and the movable cable plate 504 are both L-shaped, and the branch cable 4 is located between the fixed cable plate 501 and the movable cable plate 504. The branch cable 4 can be tightened and fixed in the current position only by the fixed cable plate 501, the mounting plate 502, the second spring 503 and the movable cable plate 504. It can be seen that the manufacturing cost of the cable arrangement mechanism 5 is lower.

[0028] When implementing, follow these steps:

[0029] 1) First, let the main cable 3 and the branch cable 4 pass through the insert tube 211 and the second waterproof ring 223;

[0030] 2) Then the clamping plate 214 clamps and fixes the main cable 3 and the branch cable 4;

[0031] 3) Then place the branch cable 4 between the fixed cable plate 501 and the movable cable plate 504;

[0032] 4) Finally, the waterproof tube 221 is threadedly connected to the insert tube 211.

[0033] In summary, the medium-voltage distribution network wiring structure can clamp and fix the main cable 3 and the branch cable 4 through two clamps 214, so it has a clamping and fixing function, and can prevent water from entering the inner side of the insert 211 through the first waterproof ring 222 and the second waterproof ring 223, so it has a waterproof function.

[0034] Moreover, the branch cable 4 can be tightened and fixed in the current position only by fixing the cable arrangement plate 501, the mounting plate 502, the second spring 503 and the movable cable arrangement plate 504. It can be seen that the manufacturing cost of the cable arrangement mechanism 5 is lower, which solves the problem that the wiring structure only has a clamping and fixing function for the main cable but no waterproof function, the U-shaped slot not only uses too many compression springs, but also the number of U-shaped slots themselves is too large, resulting in high manufacturing cost, and the wiring structure only has a waterproof function for the branch cable but no clamping and fixing function.
