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.

[0021] The utility model provides: a connector with a fastening structure, such as Figure 1-4 As shown, it includes a junction box 1, both sides of the junction box 1 are provided with wire locking nuts 8, a base 17 is fixedly installed at the bottom of the junction box 1, a back plate 7 is fixedly provided on the upper surface of the base 17, a wiring board 15 is fixedly provided on the side of the back plate 7, a fixing bolt 16 is bolted to the side of the wiring board 15 away from the back plate 7, a fastening plate 4 is slidably provided on the upper surface of the base 17 and located on the side of the wiring board 15, and a fastening assembly 3 for reinforcing the fastening strength of the wiring board 15 and the fixing bolt 16 is provided on the corresponding surface of the fastening plate 4 and the back plate 7, and two groups of cables are passed through the two groups of locking wires. Nut 8, then connect the two groups of cables through the terminal board 15, and then tighten them with the fixing bolts 16, then rotate the wire locking nut 8 to clamp the cables, then insert the fastening plate 4 and the clamping column 9 into the outer arc surface of the connecting rod 11, and then rotate the clamping column 9 to make the first limiting column 12 snap into the inside of the clamping groove 21, and then rotate the rotating disk 19 to drive the fastening plate 4 and the clamping column 9 to move toward the back plate 7, so that the fixing bolts 16 are tightened through the fastening plate 4, thereby strengthening the connection strength of the two groups of cables, thereby improving the stability of the overall connector during use.

[0022] The fastening assembly 3 includes a connecting rod 11, a first limiting column 12, a second limiting column 13 and a fixed column 14. The fixed column 14 is fixedly installed on the side of the back plate 7 close to the fastening plate 4. The connecting rod 11 is arranged through the side of the back plate 7 close to the fastening plate 4. The first limiting column 12 and the second limiting column 13 are both fixedly installed on the outer arc surface of the connecting rod 11. The first limiting column 12 and the second limiting column 13 are vertically arranged on the outer arc surface of the connecting rod 11, and the distance between the first limiting column 12 and the second limiting column 13 is consistent with the width of the fastening plate 4 and the clamping column 9, thereby ensuring that the first limiting column 12 can lock the position of the clamping column 9.

[0023] A clamping column 9 is provided on the side of the fastening plate 4 away from the back plate 7, and a through hole 20 corresponding to the first limiting column 12 is transversely opened on the side of the clamping column 9, and a clamping groove 21 corresponding to the first limiting column 12 is opened on the side of the clamping column 9 away from the fastening plate 4. When it is necessary to strengthen the fastening of the terminal block 15 and the fixing bolt 16, the clamping column 9 is rotated to make the first limiting column 12 embedded in the clamping groove 21, so that the first limiting column 12 squeezes the clamping column 9 to drive the fastening plate 4 to press against the terminal block 15 and the fixing bolt 16, thereby strengthening the overall fastening of the connector.

[0024] A rotating disk 19 is rotatably provided on one side of the back plate 7 away from the fastening plate 4, one end of the connecting rod 11 is threadedly provided inside the rotating disk 19, and the other end of the connecting rod 11 slides through the fastening plate 4, the back plate 7, the clamping column 9 and the fixing column 14. One end of the connecting rod 11 located inside the back plate 7 is provided with a thread corresponding to the inside of the rotating disk 19.

[0025] A connecting hole 10 corresponding to the first limiting column 12 is formed through the side of the fastening plate 4, and a clamping hole 18 corresponding to the fixing bolt 16 is formed on the side of the fastening plate 4 close to the back plate 7. When the fastening plate 4 presses the fixing bolt 16, the fixing bolt 16 will be embedded in the clamping hole 18, thereby tightening the fixing bolt 16 while preventing the fixing bolt 16 from rotating, and the connecting hole 10 is set to be a hole corresponding to the vertical first limiting column 12, so that the first limiting column 12 can pass through the connecting hole 10, thereby removing the fastening plate 4.

[0026] A limiting groove corresponding to the second limiting column 13 is provided on one side of the fixing column 14 close to the fastening plate 4, and the fixing column 14 is located on the upper part of the terminal block 15. When the fastening plate 4 presses the terminal block 15 and the fixing bolt 16 tightly, the first limiting column 12 is snapped into the inside of the snap-in groove 21. At this time, the second limiting column 13 is snapped into the inside of the limiting groove, thereby avoiding double insurance and preventing the connecting rod 11 from rotating, causing the fastening plate 4 to loosen.

[0027] A top cover 6 is bolted on the top of the junction box 1, and several groups of mounting blocks 2 are fixedly arranged on the side of the junction box 1. Several groups of connecting bolts 5 corresponding to the mounting blocks 2 are opened on the side of the top cover 6. After the cable wiring is completed, the connecting bolts 5 are screwed into the corresponding mounting blocks 2, so that the junction box 1 and the top cover 6 are fixedly connected, thereby protecting the internal devices of the junction box 1.
