Abstract
Abstract A coaxial electrical connector assembly including an insulative housing having a ground plate with a plurality of apertures sized to receive signal contacts without contact with the ground plate and other apertures sized to engage ground terminals is disclosed. Tabs formed by slits are deflected by the ground terminals inserted into these apertures. This coaxial connector can be employed as an input or output to signal and ground pins used in a backplane connector which form part of a backplane connector assembly for interconnection of a plurality of daughterboards to a motherboard.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
222 words
An electrical connector assembly for interconnecting a plurality of coaxial conductors to an array of ground and signal pins in a printed circuit board assembly, the connector assembly including: a plurality of signal contacts each attachable to a signal conductor in a coaxial conductor and including means for establishing contact with a signal pin; a plurality of ground contacts, each attachable to a braid surrounding the signal conductor in a coaxial conductor; and a ground plate having a plurality of first, second and third apertures, each said first aperture being larger than a signal pin so that the said signal pin can be inserted therethrough without engaging the said ground plate; each said second aperture having means for engaging a ground contact inserted therethrough; each said third aperture including means for engaging a ground pin inserted therethrough, said means for engaging a said ground contact and a said ground pin respectively in the said second and third apertures comprising a plurality of tabs having tapered edges, said tabs in said second apertures extending from one side of said ground plate and said tabs in said third apertures extending from the opposite side of said ground plate, said ground contacts being insertable into the second apertures and said ground pins being insertable into said third apertures from opposite sides of said ground plate.
Claim 2
Dependent Claim
