High speed, high density interconnect system for differential and single-ende d transmission systems on backplane / motherboards

摘要

A electrical interconnection system includes spacers (2110) comprising rows of first and second interposers (30, 32 Fig.1) , first and second pluralities of shielding members (200, 202, 204, 206 Fig 2) situated respectively therein, at least one cable (40, 42 Fig 2) comprising a central conductor (120, 122 Fig 2) and a conductive shield (128 Fig 2) and a dielectric (124 Fig 2) therebetween. The outer jacket of the cable is in electrical contact with at least some of the shielding members located in the first and second interposers. All of the cable sections have one end exposed on a first plane and a second end exposed on a second plane. One end of the cables central conductors are connected to conductive elements (300, 302, 304, 306 Fig 3) that are disposed within apertures within the interposers. The opposing end of the conductive element extends through its respective aperture. The contacts within the interposers may be buttons of coiled or depressed wire. In an alternative embodiment a spring contact located within a shouldered top hat holder may be used.
