The bus connector that this embodiment provided adopts the design of similar joint, and the contained angle between the both ends tie point can rotate the regulation at will to utilize isolation washer 7 to keep apart each electrode, the succinct stability of structure can effectively improve the construction of bus duct and arrange the flexibility.

The left end and the right end of the bent protective sleeve are respectively provided with a first connecting seat 11 and a second connecting seat 21, the butt joint end 3 of the first splicing piece 1 is fixed on the first connecting seat 11, the butt joint end of the second splicing piece 2 is fixed on the second connecting seat 21, and the front ends of the first connecting seat 11 and the second connecting seat 21 are both provided with butt joint fixing pieces 9. The first connecting seat 11 and the second connecting seat 21 are used for correspondingly fixing the butt joint end 3, and the external bus duct is convenient to butt joint. The docking fixture 9 may be a conventional bus connector structure on the market, as disclosed in the patent document with patent number CN112751300A entitled "a bus connector and bus duct", for fixedly connecting an external bus duct with the present embodiment.

The bending protection sleeve comprises an organ hose 8, and two ends of the organ hose 8 are fixedly connected with a first connecting seat 11 and a second connecting seat 21 respectively. The organ hose 8 is soft and bendable, and can effectively protect the internal structure of the equipment while the rotational degree of freedom is not influenced.

The inner sides of the first connecting seat 11 and the second connecting seat 21 are wrapped with sealing rubber strips 10. The sealing rubber strip 10 can be isolated from the outside and inside the bent protective sleeve, so that the structural safety is improved, and electric leakage is avoided.

The rotating shaft comprises a fastening bolt 61 which is connected with the rotating hole 5 in a penetrating mode, a fastening nut 62 is sleeved at the front end of the fastening bolt 61 in a threaded mode, the front end of the fastening bolt 61 penetrates through the organ hose 8, and the fastening nut 62 is arranged on the outer side of the organ hose 8.
