Power supply unit and its high current connector

Abstract

A power supply device and its high-current connector are disclosed. The power supply device includes a high-current connector and a mating bus. The mating bus includes two electrodes with opposing inner walls. The high-current connector includes an insulating structure and two mating members corresponding to the electrodes. Each mating member has two terminal groups, each terminal group including a plurality of high terminals, a plurality of middle terminals, and a plurality of low terminals. The high-conducting portion of each high terminal, the middle-conducting portion of each middle terminal, and the low-conducting portion of each low terminal are located in three staggered positions. During mating, all high, middle, and low-conducting portions of one terminal group of each mating member abut against one inner wall of each electrode, and all high, middle, and low-conducting portions of the other terminal group of each mating member abut against the other inner wall of each electrode. This achieves the effect of carrying a large current without overheating.
