Improved bus duct with efficient connection

The utility model relates to the technical field of bus ducts, in particular to an improved bus duct with high connection efficiency, which comprises bus duct shells and a connecting assembly detachably arranged between two adjacent bus duct shells, and the connecting assembly comprises an upper connecting plate and a lower connecting plate. The two adjacent bus duct shells can be quickly inserted and fixed, the upper connecting plate and the lower connecting plate can be clamped and fixed through the arrangement that the fixing blocks and the fixing grooves are matched with the limiting blocks and the limiting grooves, and fastening bolts are sequentially inserted into the first mounting holes and the second mounting holes, so that the fastening effect is improved. The connecting assembly is further fixedly connected with the bus duct shell, so that the problems of looseness and displacement deviation during splicing of multiple sections of bus ducts are avoided, stable electrical connection between the sect
