[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] The present utility model provides a highly stable terminal block Figures 1 to 7 as shown, which is provided with a safety protection structure, including a terminal board 1. A partition 2 is fixedly connected to the upper surface of the terminal board 1. A plurality of partitions 2 are provided, and the plurality of partitions 2 are equidistantly distributed. A groove 3 is opened at the top of the partition 2, and a clamping plate 4 is fixedly connected between the plurality of grooves 3. A first terminal box 5 and a second terminal box 6 are respectively arranged between two adjacent partitions 2. The first terminal box 5 and the second terminal box 6 are respectively located on both sides of the clamping plate 4, and both the first terminal box 5 and the second terminal box 6 are fixedly connected to the terminal board 1. Both the first terminal box 5 and the second terminal box 6 are used for connecting wires.

[0029] Considering that when connecting wires to the terminal block, usually only the screw fixation method is adopted, when the wire is pulled by an external force, it is easy to become loose and cause poor contact. To realize the positioning of the wire, a square box 11 is fixedly connected to the side of the first terminal box 5 facing away from the second terminal box 6. A C-shaped clamp 12 is fixedly connected to the end of the square box 11 away from the first terminal box 5. A square groove 20 is opened on the upper surface of the bottom of the C-shaped clamp 12, and the square groove 20 communicates with the square box 11. A sliding column 21 is slidably connected inside the square groove 20, and a top plate 22 is fixedly connected to the top of the sliding column 21. The wire is clamped into its interior through the opening of the C-shaped clamp 12, and the end of the wire is positioned inside the first terminal box 5. When the sliding column 21 extends out of the interior of the square groove 20, it will drive the top plate 22 to move towards the wire direction and cooperate with the C-shaped clamp 12 to complete the clamping and positioning of the wire. When the wire is accidentally pulled by an operator or other situations, since the wire is positioned inside the C-shaped clamp 12 by the top plate 22, the connection between the wire and the first terminal box 5 is kept stable, avoiding safety problems caused by loosening and improving the safety of using the terminal block.

[0030] In addition, the same reinforcement structure can also be provided on the second terminal box 6.

[0031] And a plurality of first terminal boxes 5 and second terminal boxes 6 are provided, and the terminal block can be used for mutual docking of multiple cable lines.

[0032] A first threaded rod 8 passes through the top of the first terminal box 5. The first threaded rod 8 is threadedly connected to the first terminal box 5. One end of the first threaded rod 8 located inside the first terminal box 5 is rotatably connected to a first pressing plate 23. The first pressing plate 23 abuts against the inner wall of the first terminal box 5. The top of the first threaded rod 8 is fixedly connected to a first rotating block 9. A first electric contact plate 7 is arranged inside the first terminal box 5. The first electric contact plate 7 is fixedly connected to the inner wall of the first terminal box 5. The first electric contact plate 7 cooperates with the first pressing plate 23.

[0033] During operation, the end of the wire is inserted into the first terminal box 5 and is located between the first electric contact plate 7 and the first pressing plate 23. By rotating the first threaded rod 8 through the first rotating block 9, the first pressing plate 23 moves towards the first electric contact plate 7, so that the end of the wire is fixed between the first electric contact plate 7 and the first pressing plate 23.

[0034] A control component for controlling the position of the sliding column 21 is arranged on the first terminal box 5. The control component includes a sliding groove 13, a square opening 16 and a first air cavity 19. The sliding groove 13 is opened on the inner wall of the first terminal box 5. The first air cavity 19 is opened inside the wall body of the first terminal box 5. The sliding groove 13 communicates with the first air cavity 19 through the square opening 16. The first air cavity 19 communicates with the square box 11.

[0035] The control component further includes an upper sliding plate 14, a round rod 15, a lower sliding plate 17 and a spring 18. The upper sliding plate 14 is slidably connected to the upper half of the sliding groove 13, and the upper sliding plate 14 is fixedly connected to the first pressing plate 23. The lower sliding plate 17 is slidably connected to the lower half of the sliding groove 13. One end of the spring 18 is fixedly connected to the lower surface of the lower sliding plate 17, and the other end of the spring 18 is fixedly connected to the bottom of the sliding groove 13. The round rod 15 is fixedly connected to the upper surface of the lower sliding plate 17. The upper sliding plate 14 abuts against the top of the round rod 15.

[0036] During operation, the end of the wire is inserted into the first terminal box 5 and is located between the first electric contact plate 7 and the first pressing plate 23. By rotating the first threaded rod 8 through the first rotating block 9, the first pressing plate 23 moves towards the first electric contact plate 7. When the first pressing plate 23 moves, it drives the upper sliding plate 14 to slide downward inside the sliding groove 13. The upper sliding plate 14 presses the lower sliding plate 17 to slide downward through the round rod 15. The gas in the lower half of the sliding groove 13 enters the inside of the square groove 20 through the square opening 16, the first air cavity 19 and the square box 11. The sliding column 21 extends out of the inside of the square groove 20, which will drive the top plate 22 to move towards the wire direction and cooperate with the C-shaped clamp 12 to complete the clamping and positioning of the wire.

[0037] A second threaded rod 26 passes through the top of the second terminal box 6. The second threaded rod 26 is threadedly connected to the second terminal box 6. One end of the second threaded rod 26 located inside the second terminal box 6 is rotatably connected to a second pressing plate 25. The second pressing plate 25 abuts against the inner wall of the second terminal box 6. The top of the second threaded rod 26 is fixedly connected to a second rotating block 27.

[0038] A second electric contact plate 24 is arranged inside the second terminal box 6. The second electric contact plate 24 is fixedly connected to the inner wall of the second terminal box 6. The second terminal box 6 cooperates with the second pressing plate 25.

[0039] During operation, the end of the wire is inserted into the second terminal box 6 and is located between the second electric contact plate 24 and the second pressing plate 25. By rotating the second threaded rod 26 through the second rotating block 27, the second pressing plate 25 moves towards the second electric contact plate 24, so that the end of the wire is fixed between the second pressing plate 25 and the second electric contact plate 24.

[0040] Considering that the general connection and fixing method of the existing terminal is bolt fastening connection, and when connecting, the wire is inserted into the directly energized connecting piece on the terminal, with poor safety. Therefore, it is generally necessary to cut off the power supply to make the connection. And it is rather troublesome to cut off the power supply in order to connect a cable. Therefore, a first electric contact piece 10 is provided on the first terminal box 5. The first electric contact piece 10 is connected to the first electric contact plate 7. A second electric contact piece 31 is provided on the second terminal box 6. The second electric contact piece 31 is connected to the second electric contact plate 24.

[0041] A protection component is arranged between the first terminal box 5 and the second terminal box 6. The protection component includes a third threaded rod 28, a third rotating block 29 and a pressing piece 30. The third threaded rod 28 is rotatably connected to the clamping plate 4. The pressing piece 30 is slidably connected between the corresponding two partition plates 2. The pressing piece 30 cooperates with the first electric contact piece 10 and the second electric contact piece 31. The third rotating block 29 is fixedly connected to the top of the third threaded rod 28.

[0042] During operation, after the first terminal box 5 and the second terminal box 6 are respectively connected to the wire, the third threaded rod 28 is rotated through the third rotating block 29, and the pressing piece 30 moves downward and abuts against the first electric contact piece 10 and the second electric contact piece 31, completing the connection of the first electric contact piece 10 and the second electric contact piece 31. By providing structures such as the third threaded rod 28, the third rotating block 29 and the pressing piece 30, when the first terminal box 5 and the second terminal box 6 are connected to the wire, it is not necessary to cut off the overall power supply for connection, and it is convenient to repair and replace the first terminal box 5 and the second terminal box 6, ensuring the safety of the operation.
