Grounding for electrical connectors

An electrical connector, comprising:

• a first shell having at least one first wall made of an electrically conductive material, wherein the at least one first wall forms a first cavity;
• an insert disposed within the first cavity;
• at least one connector pin disposed within and traversing the insert;
• an electrically conductive face seal that abuts against a distal end of the insert within the first cavity and against an inner surface of the at least one wall of the first shell, wherein the at least one connector pin traverses at least one first aperture in the electrically conductive face seal, wherein the electrically conductive face seal provides a solid ground path with the first shell;
• and
• at least one insulating bushing disposed within the at least one first aperture in the electrically conductive face seal, wherein the at least one insulating bushing is further disposed between the electrically conductive face seal and the at least one connector pin, wherein the at least one insulating bushing electrically isolates the at least one connector pin from the electrically conductive face seal;
• wherein the at least one first aperture in the electrically conductive face seal comprises a first portion and a second portion, wherein the first portion has a first outer perimeter, and wherein the second portion has a second outer perimeter, wherein the first outer perimeter is greater than the second outer perimeter.
