[0035] When the bus duct 1 is connected with the horizontal bend 2, the protective moving plate 10 is rotated, and a part of the conductive row joint 4 on the connecting end of the bus duct 1 is exposed.

[0043] Further, the inner wall between the displacement frame 5 and the pushing and spacing member 7 is provided with a reinforcing frame 23. The reinforcing frame 23 improves the stability of the pushing and spacing member 7.

[0044] The working principle of the bus duct and the horizontal bend of the bus duct thereof in the embodiment is as follows: first, the protective moving plate 10 is rotated to expose a part of the electric busbar connector 4 on the connecting end of the bus duct 1, and the elastic member 12 generates an elastic force at this time.

[0045] Then, the outer cylinder 8 is rotated on the horizontal bend 2, the two threaded columns 9 connected by threads on the outer cylinder 8 are relatively moved, the two threaded columns 9 drive the two displacement frames 5 to relatively move, and the two displacement frames 5 relatively move, the conical distance adjusting member 6 and the pushing and spacing member 7 on the opposite sides are driven to move. The four branches of the electric busbar connector 4 are simultaneously moved and dispersed by the inclined surface of the conical distance adjusting member 6, so that the four branches of the electric busbar connector 4 on the horizontal bend 2 are connected with the four branches of the electric busbar connector 4 on the bus duct 1.

[0046] Then, the branches of each electric busbar connector 4 are separated by the insulating plate, and finally the protective moving plate 10 is rotated to the between the two side sealing plates 3 of the bus duct 1 by the elastic force of the elastic member 12.
