HIGH-SPEED CONNECTOR

A high-speed connector, comprising several wafers (101) mounted in parallel, wherein each wafer comprises an insulator (1011) and shielding plates (1012, 1013) mounted on two sides of the insulator; differential pairs are arranged in the insulator; the shielding plates on two sides of the insulator are bent at crimping ends of the differential pairs so as to form a plurality of shielding cavities (1014); and each shielding cavity accommodates the crimping end of one differential pair. The shielding plates are arranged on two sides of each wafer, and folded pieces are bent on the shielding plates on each side in the direction orthogonal to the shielding plate so as to form side walls orthogonal to the shielding plates, so that a three-dimensional and circumferential differential pair isolation cavity is formed in an area where the differential pairs come into contact with a circuit board, the differential pairs are in a state of being completely enclosed by the shielding plates and the folded pieces, and an ar
