[0021] According to the above structure, when docking, several connecting plates 3 are respectively contacted and connected with several docking components 4, so as to realize the electrical connection of the two bus ducts. After the docking is completed, the protective component 2 is covered on the outside of the docking point to protect the inner connecting plates 3 and docking components 4, to prevent water and dust in the air from falling on the connecting plates 3 and docking components 4, and to improve the sealing and protective performance of the bus duct.

[0022] like Figure 3 and 4 As shown, the docking component 4 includes a docking plate 41 arranged at one end of the busbar trough body 1, an insulating block 42 is fixedly connected to one side of the docking plate 41, a slide groove 43 is symmetrically opened on one side of the insulating block 42, and a slide bar 31 matching the slide groove 43 is symmetrically opened on one side of the connecting plate 3 and one side of one of the baffles 5.

[0023] According to the above structure, when docking, the docking plate 41 and the insulating block 42 are inserted into the gap between two adjacent connecting plates 3, and the docking plate 41 is contacted and connected with the corresponding connecting plate 3 to achieve electrical connection between the two. The setting of the insulating block 42 can increase the extrusion force between the docking plate 41 and the connecting plate 3, thereby improving the stability of the connection between the docking plate 41 and the connecting plate 3. When docking, the two slide bars 31 on one side of the connecting plate 3 are respectively slid into the two slide grooves 43 on one side of the insulating block 42 to improve the stability of the slide groove 43 in the gap, thereby further improving the stability of the connection between the docking plate 41 and the connecting plate 3.

[0024] like Figure 3 As shown, the baffle plate 5 is L-shaped, and a plurality of connecting plates 3 are arranged between two baffle plates 5 .

[0025] According to the above structure, the two baffles 5 are limited at both sides respectively, ensuring that the plurality of connecting plates 3 and the plurality of docking components 4 are between the two baffles 5 after docking, thereby preventing deformation due to extrusion.

When docking, the docking plate 41 and the insulating block 42 are inserted into the gap between two adjacent connecting plates 3, and the docking plate 41 is contacted and connected with the corresponding connecting plate 3 to realize the electrical connection between the two. The setting of the insulating block 42 can increase the extrusion force between the docking plate 41 and the connecting plate 3, thereby improving The stability of the connection between the docking plate 41 and the connecting plate 3. During the docking process, the two slide bars 31 on one side of the connecting plate 3 slide into the two slide grooves 43 on one side of the insulating block 42 respectively, thereby improving the stability of the slide groove 43 in the gap and further improving the stability of the connection between the docking plate 41 and the connecting plate 3. The two baffles 5 are respectively limited on both sides to ensure that after docking, a plurality of connecting plates 3 and a plurality of docking components 4 are between the two baffles 5 to prevent deformation due to extrusion. When the two bus ducts are plugged in and docked, the plug 6 is inserted into the inside of the sleeve 21. After being plugged in, the connecting cover 22 is sleeved on one end of the bus duct body 1 of the adjacent bus duct, thereby improving the sealing and improving the protection strength of the connecting plate 3 and the docking component 4.
