When the second energized copper sheet 520 is inserted into the insulating ceramic sheet 420, the second connecting sleeve 500 moves toward the first connecting sleeve 400, and the second connecting ring 510 approaches the first connecting ring 410. The connecting plate 412 on one side of the first connecting ring 410 is inserted into the interior of the mounting groove 512. When the protruding elastic blocks 413 on both sides of the connecting plate 412 contact the inner wall of the mounting groove 512, the elastic blocks 413 are squeezed into the interior of the telescopic groove as the connecting plate 412 is inserted into the interior of the mounting groove 512, compressing the retaining spring 414. When the sealing ring 411 on one side of the first connecting ring 410 is inserted into the interior of the sealing groove 511, one end of the connecting plate 412 passes through the mounting groove 512, and the elastic block 413 moves out of the mounting groove 512.

[0050] S3. The user pushes the sealing sleeve 300, and the sealing sleeve 300 is sleeved on the surface of another bus duct body 100, and fits with one side of the connecting protrusion 130 on the surface of the bus duct body 100. The sealing sleeve 300 can protect the first connecting sleeve 400 and the second connecting sleeve 500;

[0051] S4. The user drives the connecting block 135 through the buckle opening 136, and the connecting block 135 drives the connecting rod 133 to move. The connecting rod 133 drives the movable block 134 to move inside the movable groove 131 to compress the compression spring 132. The user rotates the rotating bar 320. When the rotating bar 320 rotates to the position of the connecting rod 133, the connecting rod 133 is inserted into the inside of the slot 321. As the rotating bar 320 rotates, the connecting rod 133 moves relatively inside the slot 321. When the rotating bar 320 cannot rotate, the user releases the connecting block 135, and the movable block 134 moves inside the movable groove 131 under the action of the compression spring 132. The movable block 134 drives the connecting block 135 to move through the connecting rod 133, so that the connecting block 135 is inserted into the inside of the connecting groove 322. The rotating bar 320 can be limited, so that the sealing sleeve 300 is connected to the adjacent bus duct body 100, thereby facilitating the connection between adjacent bus duct bodies 100.
