[0048] It should be noted that the side of the support assembly 131 away from the monomer 121 is provided with a first assembly hole, and the outer shell 110 is provided with a second assembly hole opposite the first assembly hole; the bus duct unit 100 further comprises a limiting piece 140, the limiting piece 140 is provided through the first assembly hole and the second assembly hole, so as to limit the support assembly 131 in the inner of the outer shell 110.
[0049] Wherein, the cross section of the first assembly hole can be a complete circular structure, or a notched circular structure.
[0050] Specific to the embodiment, the cross section of the first assembly hole is a notched circular structure, and the notch on the first assembly hole is located on the side of the support assembly 131 away from the monomer 121, under the joint action of each monomer 121 and the limiting piece 140, the fixation of the support assembly 131 can be realized.

[0059] It should be noted that in the busbar trough unit 100 of the utility model, the outer shell 110 can be made of steel material, which has good strength and can be sealed by the poured first insulation piece to achieve better sealing effect. Since the outer shell 110 is not manufactured by pouring, the use of insulating material can be reduced, and the cost can be saved.

[0066] It should be noted that the joint protection shell 200 includes two protection side plates 210 and two protection cover plates 220, and the two protection side plates 210 and the two protection cover plates 220 cooperatively form a containing cavity, and the connector 300 is arranged in the containing cavity.
