Abstract: A substrate assembly includes a first substrate having a first surface and an oppositely facing second surface. Signal pathways are provided on the first surface. The signal pathways extend to first openings which extend inward from an edge of the substrate. First ground pathways are provided on the first surface. Each of the first ground pathways are positioned adjacent at least one of the signal pathways. The first ground pathways extend to second openings which extend inward from the edge of the substrate. Signal contacts are mounted to the first substrate. The signal contacts have first mounting surfaces which provide mechanical and electrical engagement with the first openings. Ground contacts are mounted to the first substrate. The ground contacts have second mounting surfaces which provide mechanical and electrical engagement with the second openings.

Abstract: An electrical connector assembly for mating with a mating connector assembly. The connector assembly includes a housing with a cable receiving portion and a mating portion. The housing has a first surface and an oppositely facing second surface. The mating portion has a mating projection which extends from the first surface in a direction away from the second surface. The mating projection has a circular cross-sectional configuration. The mating projection has an angled wall which extends from the first surface to a mating face, the angled wall is angled relative to a plane of the first surface and a plane of the mating face. The mating face has contacts which extend therethrough. The contacts has circular engagement sections arranged concentrically about a center of the mating face. A nonconductive coating applied to the angled wall.
