Power connector assembly

A power connector assembly, being adapted to be mounted to a first board, wherein the power connector assembly comprises:

• a first mating terminal mounted to the first board and electrically connecting the first board, the first mating terminal has a fitting portion and a supporting rod and a mating rod which extend from the fitting portion and are arranged as a step from large to small, the mating rod and the supporting rod therebetween have a position-limiting step portion constituted by the step, the first mating terminal being mounted to the first board by means of the fitting portion;
• a busbar;
• a first receptacle mounted to the busbar and electrically connecting the busbar, the first receptacle comprises a conductive shell which is mounted to the busbar and a conductive spring which is provided in the conductive shell and is electrically connected with the conductive shell, wherein, the mating rod of the first mating terminal inserts into the first receptacle and elastically contacts and electrically connects the conductive spring;
• a position-limiting member provided to a tip of the mating rod of the first mating terminal, the first receptacle is retained between the position-limiting step portion of the first mating terminal and the position-limiting member with a gap, and the first receptacle is capable of rotating relative to the mating rod, so that the busbar is capable of rotating relative to the first mating terminal and the first board.
