Abstract:
1. An electrical connector comprising: a connector housing having mating and terminating ends, the connector housing having a housing cavity and a leading edge at the mating end that defines an opening to the housing cavity, wherein a central axis extends through the housing cavity between the mating and terminating ends, the connector housing forming an internal step that extends radially toward the central axis in the housing cavity, the internal step having a step surface that faces toward the mating end; a dielectric insert positioned within the housing cavity, the insert having an engagement end, a back end, and an intermediate portion extending therebetween; and an electrical contact held by the insert along the central axis and configured to engage a coupling connector in the housing cavity; wherein the insert has a recess surface that faces the mating end and extends a radial distance outward from the electrical contact, the insert including a dielectric rim at the engagement end that projects an axial distance from the recess surface toward the mating end, the dielectric rim surrounding and being radially spaced from the electrical contact, the dielectric rim and the recess surface defining an impedance-control space that circumferentially surrounds the electrical contact about the central axis, wherein the axial distance of the dielectric rim and the radial distance of the recess surface are sized to obtain a target impedance for the electrical connector; wherein the dielectric insert is sized and shaped to be inserted through the opening in a direction that is from the mating end to the terminating end in order to position the insert at an operative location, the step surface of the connector housing directly engaging the back end of the insert to positively stop the insert at the operative location.
