Abstract

A dielectric member for controlling impedance for use in an electrical connector. The dielectric member including a housing made of dielectric material and a dielectric rib. The dielectric rib extends from a conductor receiving end of the housing in a direction away from a mating end. The rib is spaced equidistant from each of the conductor receiving openings. The rib extends in a direction which is essentially parallel to a longitudinal axis of the housing. Conductor engaging surfaces are provided on the rib, with a first conductor engaging surface of the conductor engaging surfaces being opposed to a second conductor engaging surface of the conductor engaging surfaces. The first conductor engaging surface and the second conductor engaging surface are spaced apart a distance, wherein the impedance of the conductors proximate the rib is approximately the same as the impedance of the cable.
