The outer surface of the end block 4 is fixedly connected to a baffle 6, and the inner surface of the baffle 6 is rotatably connected to a fastening component 7. A groove 14 is provided in the wall at the bottom of the center block 2, and the side of the groove 14 is set as a curved surface 15. The groove 14 is connected to the protrusion on the bus duct. Since the curved surface 15 is bent upward, any point of the corresponding protrusion on the bus duct can fit with the curved surface 15, so that the plug is fixed in position when it is not installed by bolts. The side threaded hole 3 is also provided in the wall of the center block 2, and the side threaded hole 3 passes through the inner wall of the center block 2 and extends to the outside of the shell 1. After the bolt is inserted into the side threaded hole 3, the bolt is rotated to connect and fix the connecting side plate installed on the outside of the bus duct to the plug.

[0022] The bottom of the end block 4 is fixedly connected to the outer surface of the center block 2, and the outer surface of the center block 2 is fixedly connected to the outer surface of the baffle 6. Since there is a certain space between the center block and the end block 2, when the position of the plug on the bus duct is fixed, the baffle 6 can prevent small debris from entering the plug. A through hole 13 is opened in the wall at the bottom of the outer shell 1, and the through hole 13 is also opened in the wall of the baffle 6. The outer surface of the fastening assembly 7 is threadedly connected to the inner surface of the outer shell 1. The fastening assembly 7 on the baffle 6 is rotated so that the lower half of the fastening assembly 7 is inserted into the bus duct. The baffle 6 can fix the fastening assembly 7 in the plug and it is not easy to lose, and the baffle 6 can prevent small debris from entering the plug and affecting the rotation of the fastening assembly 7.

[0023] The fastening assembly 7 includes a knob 8, the bottom of which is fixedly connected to a connecting rod 9, the outer surface of which is slidably connected to a slider 10, a sliding groove 12 is provided in the wall of the connecting rod 9, the outer surface of the sliding groove 12 is slidably connected to the outer surface of the slider 10, and the knob 8 is turned to rotate the connecting rod 9, and the upper half of the slider 10 is stuck in the sliding groove 12 on the connecting rod 9, then the rotating connecting rod 9 will drive the slider 10 to rotate, and the lower surface of the slider 10 is fixedly connected to a threaded rod 11, the outer surface of the threaded rod 11 is threadedly connected to the inner surface of the shell 1, the outer surface of the connecting rod 9 is rotatably connected to the inner surface of the baffle 6, the threaded rod 11 rotates with the slider 10, and the rotating threaded rod 11 will be raised and lowered in the through hole 13 due to its threaded connection with the inner surface of the shell 1, that is, rotating the knob 8 can make the threaded rod 11 descend and be inserted into the corresponding hole on the bus duct, so that the plug is also fixed on the bus duct in the vertical direction.

[0024] Working principle:

[0025] When in use, after the plug made of aluminum die-casting is placed as a whole at the end of the bus duct, the groove 14 at the bottom of the center block 2 is connected to the protrusion on the bus duct. Since the curved surface 15 is bent upward, the corresponding protrusion on the bus duct can fit with the curved surface 15, so that the plug is fixed in position when it is not installed by bolts. Then, the installation position on the connecting side plate installed outside the bus duct is aligned with the side threaded holes 3 on the shell 1 and the center block 2. Then, the bolts are inserted into the side threaded holes 3 and then rotated to connect and fix the connecting side plate to the plug. Then, the fastening assembly 7 on the baffle 6 is rotated so that the lower half of the fastening assembly 7 is inserted into the bus duct. First, the knob 8 is rotated to make the connection The rod 9 rotates, and since the upper part of the slider 10 is stuck in the slide groove 12, the rotating connecting rod 9 will drive the slider 10 to rotate, and the lower surface of the slider 10 is fixedly connected to the threaded rod 11, and the threaded rod 11 will rotate accordingly. The rotating threaded rod 11 will be raised and lowered in the through hole 13 due to its threaded connection with the inner surface of the shell 1. The knob 8 is turned to make the threaded rod 11 descend and insert it into the corresponding hole on the bus duct, so that the plug is also fixed on the bus duct in the vertical direction. When installing the cover plate, the operator aligns the installation position of the cover plate installed on the upper surface of the plug with the installation holes 5 on the end blocks 4 on both sides of the inside of the shell 1, and then uses bolts to fix the cover plate and the plug.
