The partition 2 10 is movably connected to the connection frame 1, the partition 1 9 is fixed in the connection frame 1, and the rotating rod 11 is connected to a positioning mechanism for positioning the plug board 7.

[0020] The existing bus duct includes a busbar body 5 , two plug-in boards 7 connected to the ends of the busbar body 5 , and four copper bars 6 , wherein the four copper bars 6 are located between the two plug-in boards 7 .

[0021] When the distance between the two busbar bodies 5 is appropriate, the rotating handle 2 drives the rotating rod 11 to rotate, so that the two partition plates 3 14 move synchronously in the direction close to the partition plate 1 9, and the multiple copper bars 6 are squeezed to achieve a tighter fit between the connected copper bars 6, avoiding the hidden danger of poor contact, and replacing the traditional bolt locking without the need for tools; at the same time, the rotation of the rotating rod 11 can drive the two clamping plates 3 to approach each other, so that the positioning block 13 is pressed against the corresponding positioning groove 8, and the positioning and locking of the plug plate 7 is achieved, thereby improving the stability of the connection between the two busbar bodies 5 and the connecting frame 1. It is safe and reliable to use, flexible and convenient to operate, and shortens the operation time.

[0022] The insulating partition also includes a plurality of movable blocks 17, which are connected to the top and bottom ends of partition one 9, partition two 10, and partition three 14. An upper slide groove 16 and a lower slide groove 12 are provided inside the connecting frame 1. The movable blocks 17 match the upper slide groove 16 and the lower slide groove 12 to further improve the stability of the movement of partition three 14 and partition two 10.

[0023] The rotating rod 11 is threadedly connected to the moving block 17 of the partition three 14, and the internal threads of the two moving blocks 17 are in opposite directions. The rotating rod 11 is slidingly connected to the moving block 17 of the partition two 10, and the moving block 17 of the partition one 9 is fixedly connected to the connecting frame 1.

[0024] When the rotating rod 11 rotates clockwise, the two partition plates 3 14 approach each other to squeeze and fix the copper bus 6. At this time, the spring 18 is compressed, and the two clamping plates 3 approach each other synchronously, so that the positioning block 13 is connected to the corresponding positioning groove 8 to achieve the locking purpose; when the rotating rod 11 rotates counterclockwise, the two partition plates 3 14 move away from each other, and the compressed spring 18 returns, synchronously driving the two partition plates 2 10 to return, which is convenient for synchronously loosening multiple copper bus bars 6, and the two clamping plates 3 move away from each other synchronously, so that the positioning block 13 is separated from the corresponding positioning groove 8 to achieve the loosening purpose.

[0025] A plurality of springs 18 are arranged in the upper slide groove 16 and the lower slide groove 12 , and both ends of the spring 18 are connected to the moving block 17 .

[0027] The rotating rod 11 is threadedly connected to the two sliding blocks 15, the internal threads of the two sliding blocks 15 are in opposite directions, the end of the rotating rod 11 is connected to the handle 2, and the rotating rod 11 is rotatably connected to the connecting frame 1 to improve the rotation stability of the rotating rod 11.

[0028] Slots 4 matching the plug-in boards 7 are provided at the top and bottom of the connection frame 1. The plug-in boards 7 at the ends of the busbar bodies 5 can be inserted into the connection frame 1. The plug-in boards 7 slide on the slots 4 to change the spacing between the two busbar bodies 5 and adjust according to installation requirements.

[0029] Working principle: insert the ends of the two busbar bodies 5 into the connection frame 1, slide the plug-in board 7 on the slot 4, apply thrust or pull force to the busbar body 5, and change the distance between the two busbar bodies 5. At this time, the positioning block 13 is aligned with the positioning slot 8. When the distance between the two busbar bodies 5 is appropriate, the rotating handle 2 drives the rotating rod 11 to rotate. When the rotating rod 11 rotates clockwise, the two partitions 3 14 move synchronously in the direction close to the partition 1 9, so as to achieve the extrusion and fixation of the copper bar 6, and the fit is tighter, and the hidden danger of contact failure is not easy to occur. At this time, the spring 18 is in a compressed state. At the same time, the rotating rod 11 can drive the two clamping plates 3 to approach each other, so that the positioning block 13 is pressed against the corresponding positioning slot 8, and the clamping plate 3 and the plug-in board 7 are docked, thereby improving the stability of the connection between the two busbar bodies 5 and the connection frame 1, preventing the copper bar 6 from loosening, and using it safely and reliably. At this time, the rotating rod 11 is in a tightened state. When the busbar body 5 is to be loosened, the rotary handle 2 drives the rotating rod 11 to rotate in a counterclockwise direction, so that the two partition plates 3 14 move away from each other, and the compressed spring 18 drives the partition plate 2 10 to return, thereby loosening the multiple copper bars 6. At the same time, the two clamping plates 3 move away from each other, so that the positioning block 13 is separated from the positioning groove 8, and the plug-in plate 7 is loosened. The spacing between the two busbar bodies 5 can be adjusted again, and the operation is flexible and convenient with high efficiency.
