Abstract

An electrical connector is provided for mating with a complementary connector. The electrical connector includes a dielectric housing having a mating portion. A cross-shaped ground plate structure is disposed in the mating portion of the housing when the electrical connector is mated with the complementary connector. The cross-shaped ground plate structure defines four plate edges and four quadrants. At least one terminal is mounted in the mating portion of the housing in at least some of the quadrants defined by the cross-shaped ground plate structure. A pair of outboard terminals are mounted in the mating portion of the housing outside a pair of the plate edges of the cross-shaped ground plate structure.
