[0027] Please refer to Figures 1-3 , the present invention provides a new technical solution: a connecting device for a busbar trunking, used to connect two busbar trunking bodies 1. A plurality of docking copper bars 2 are fixedly connected to both busbar trunking bodies 1, and two insulating protective side plates 17 are fixedly connected to both busbar trunking bodies 1. A protective shell 6 is fixedly installed between the two busbar trunking bodies 1 by screws;

[0028] A docking fixing component is arranged between the two busbar trunking bodies 1. The docking fixing component is used to connect the two busbar trunking bodies 1. The docking fixing component includes a torsion-shear bolt 3, an insulating connection plate 4, an inner hole insulating sleeve 5 and a guide post 8;

[0029] An equidistant adjustment component is provided between two busbar trunking bodies 1. The equidistant adjustment component is used to adjust the spacing of a plurality of insulating connection plates 4 so as to facilitate alignment with different butt copper bars 2. The equidistant adjustment component includes a first roller 10, a chute rail 11, a pulling plate 12, a gradient chute 13 and a second roller 16;

[0030] The torsion-shear type bolt 3 in the butt joint fixing component penetrates through a plurality of insulating connection plates 4. Inner hole insulating sleeves 5 for insulation are provided at the connection positions between the torsion-shear type bolt 3 and the insulating connection plates 4. Two guide posts 8 rotatably penetrate through a plurality of insulating connection plates 4.

[0031] Furthermore, inner hole insulating sleeves 5 of the same type are provided at the connection positions between the two guide posts 8 and the insulating connection plates 4. The surfaces of the plurality of insulating connection plates 4 close to the corresponding butt copper bars 2 are all made of conductive materials. The insulating connection plates 4 are used to connect two corresponding butt copper bars 2;

[0032] A guide post fixing plate 7 for fixing the guide posts 8 is fixedly connected between the screw head end of the insulating connection plate 4 and the two guide posts 8. A nut is threadedly sleeved on the end of the torsion-shear type bolt 3 away from the screw head. The torsion-shear type bolt 3 is a torsion-shear type high-strength bolt.

[0033] Furthermore, the equidistant adjustment component further includes a plurality of roller fixing posts 9. The plurality of roller fixing posts 9 are all fixedly connected to the upper surface of the insulating connection plate 4. The plurality of first rollers 10 are all rotatably connected to the outer surfaces of the corresponding roller fixing posts 9.

[0034] Furthermore, the two chute rails 11 are both rotatably connected to the corresponding busbar trunking bodies 1. The pulling plate 12 is arranged between the two chute rails 11. The gradient chute 13 is opened on the outer surface of the pulling plate 12.

[0035] Furthermore, the spacing of the plurality of gradient chutes 13 is in a uniform gradient shape. The outer surfaces of the plurality of first rollers 10 are respectively adapted to the inner walls of the corresponding gradient chutes 13. The outer surface of the first roller 10 is in an hourglass shape.

[0036] Furthermore, a handle 14 for pulling the pulling plate 12 is fixedly connected to the upper surface of the pulling plate 12. A fixing shaft 15 is fixedly connected to one end of the pulling plate 12. The two second rollers 16 are respectively rotatably connected to both ends of the fixing shaft 15. The two second rollers 16 are respectively slidably connected to the inner walls of the corresponding chute rails 11.

[0037] Further, when in use, by setting the pulling handle 14, the handle 14 drives the second roller 16 to move in the chute rail 11 through the fixed shaft 15 on the pulling plate 12. When the pulling plate 12 moves, it can drive a plurality of first rollers 10 to contract equidistantly and approach each other through a plurality of gradient chutes 13 thereon. This enables the plurality of first rollers 10 to drive a plurality of insulating connection plates 4 to slide along the axis direction of the guide post 8 through the roller fixing posts 9 thereon, so that the distance between the plurality of insulating connection plates 4 can gradually become smaller until the distance between the plurality of insulating connection plates 4 can be adapted to the docking copper bar 2. At this time, rotate the chute rail 11 so that the chute rail 11 rotated by 90° can drive the plurality of insulating connection plates 4 and the like thereon to rotate to between the two docking copper bars 2. Then, by continuously pulling the handle 14, drive the plurality of insulating connection plates 4 to continuously tighten. This enables uniform adjustment, which enables the conductive material on the insulating connection plates 4 to be initially connected to the corresponding two docking copper bars 2. At this time, by tightening the nut on the torque-shear bolt 3, the positions of the plurality of insulating connection plates 4 are initially fixed. Then, by rotating the pulling plate 12 by 180° until it is separated from the plurality of chute rails 11, at this time, continuously tighten the gradient chute 13 until the screw head of the gradient chute 13 is broken off. At this time, the tightening degree of the torque-shear bolt 3 reaches the qualified standard. At this time, the insulating connection plates 4 fix the two docking copper bars 2 completely. Then, by using screws, the protective housing 6 is fixedly installed on the outer surfaces of the two busbar bodies 1. At this time, the installation is completed. By setting the equidistant adjustment component, it is allowed to flexibly adjust the distance between the insulating connection plates 4 according to actual needs to adapt to docking copper bars 2 of different sizes and specifications. This improves the adaptability and versatility of the equipment, and by setting the torque-shear bolt 3 in the docking and fixing component, it ensures good contact between the insulating connection plates 4 and the docking copper bars 2, improving the reliability and stability of the electrical connection.

[0038] Further, through the set equidistant adjustment component, the distance between the plurality of insulating connection plates 4 can be effectively adjusted. Through the design of the equidistant adjustment component and the gradient chute 13, the automatic and uniform adjustment of the distance between the insulating connection plates 4 is realized. This improves the installation efficiency and accuracy, and also avoids the problem in the traditional method that the adjustment of the distance between the plurality of insulating connection plates 4 requires a large amount of manual operation and it is difficult to ensure the uniformity and accuracy of the distance, making it difficult to align with the docking copper bar 2 for connection.

[0039] Working principle: When in use, by setting and pulling the handle 14, the handle 14 drives the second roller 16 to move in the chute rail 11 through the fixed shaft 15 on the pulling plate 12. When the pulling plate 12 moves, it can drive a plurality of first rollers 10 to contract equidistantly and approach each other through the plurality of gradient chutes 13 thereon. This enables the plurality of first rollers 10 to drive a plurality of insulating connecting plates 4 to slide along the axis direction of the guide post 8 through the roller fixing posts 9 thereon, so that the distance between the plurality of insulating connecting plates 4 can gradually become smaller until the distance between the plurality of insulating connecting plates 4 is adapted to the docking copper bar 2. At this time, rotate the chute rail 11 so that the chute rail 11 rotated by 90° can drive the plurality of insulating connecting plates 4 and the like thereon to rotate to between the two docking copper bars 2. Then, by continuously pulling the handle 14, drive the plurality of insulating connecting plates 4 to continuously tighten, which enables uniform adjustment, so that the conductive material on the insulating connecting plates 4 can be initially connected to the corresponding two docking copper bars 2. At this time, by tightening the nut on the torque-shear type bolt 3, the positions of the plurality of insulating connecting plates 4 are initially fixed. Then, by rotating the pulling plate 12 by 180° until it is separated from the plurality of chute rails 11, at this time, continuously tighten the gradient chute 13 until the screw head of the gradient chute 13 is broken off. At this time, the tightening degree of the torque-shear type bolt 3 reaches the qualified standard. At this time, the insulating connecting plates 4 fix the two docking copper bars 2 completely. Then, by using screws, fix and install the protective housing 6 on the outer surfaces of the two busbar bodies 1. At this time, the installation is completed.
