Adapter usable with an electronic interconnect for high speed signal and data transmission

An adapter for an electronic interconnect assembly has a high speed coaxial interconnect for a coaxial transmission line having a central signal conductor and a surrounding shield conductor. The coaxial interconnect has a male side and a female side, with the female side including a shield sleeve having a chamber that receives a male shield contact on the male side. The shield sleeve has a contact with a compliant portion that flexibly grips the male shield contact. A mechanical alignment facility portion selected from a pair of alignment facility portions including a closely mating pocket and body has one of the male side or female side of the coaxial interconnect. An electrical signal connector is electrically coupled to the selected male or female of the coaxial interconnect.
