A high-current connector and a high-current connection device, the high-current connection device comprises a circuit board and at least one group of (two) high-current connectors. Each high-current connector comprises a conductive mating member and a conductive combined shunt. The conductive mating member has a main body and an alignment soldering leg, the main body is formed as a columnar body and has a bottom surface and a top surface, the alignment soldering leg integrally extends from the bottom surface and protrudes from the bottom surface. The conductive combined shunt has a base portion combined with the main body and a plurality of shunt pins extending from at least two opposite sides of the base portion, and the plurality of shunt pins are positioned on both sides of the alignment soldering leg. The alignment soldering leg of the high-current connector is inserted into and electrically connected to the middle conductive holes of the circuit board, and the shunt pins of the high-current connector are respectively inserted into and electrically connected to the first conductive holes of the circuit board.
