Abstract
Abstract A shielded electrical connector is disclosed for mating with a complementary electrical connector. The shielded connector includes a dielectric housing. A first region of the housing has a plurality of first terminals mounted therein in a first given array for interconnection with a plurality of first terminals of the complementary connector. A second region of the housing has a plurality of second terminals mounted therein in a second given array for interconnection with a plurality of second terminals of the complementary connector. An air gap is provided in the dielectric housing between the first and second arrays of terminals to form a barrier to reduce the capacitive coupling and crosstalk between the terminals in the first and second arrays thereof.
