<p>A bus connector comprises an insulating coating (1) and a bracket (3) provided in the inner cavity of the insulating coating. The bracket has the shape of a cylinder. The side wall of the bracket is provided with multiple locking slots (31). A contact piece (41,42) is located in each locking slot. Lengths of the contact pieces in adjacent locking slots are different so as to form two or more groups of contact piece groups (4) with different lengths. The contact pieces with different lengths in the contact piece groups are orderly mounted in the locking slots of the bracket at intervals to form two or more turns of contact piece contact rings (5) at two ends of the bus connector. Spring mechanisms (6) are formed around two ends of the contact piece groups. The bus connector increases electrical contact area between the contact piece and the bar-shaped contact of the ring main unit, so as to spread the contact heating points, reduce the local temperature rise, and improve conductivity.</p> |
