Electrical connector assembly and system

An electrical connector system comprising:

• a header comprising a leading end having a plurality of contact pins that are insertable into an electronic device and a plurality of separated stripline ground plates extending from the leading end toward a mating end of the header;
• and
• an electrical connector assembly coupleable with the mating end of the header, the electrical connector assembly comprising a plurality of electrical connectors secured in a stacked configuration, each electrical connector including:
• a plurality of electrical cable terminations for mating with a corresponding plurality of contact pins of the header, each electrical cable termination comprising:
• a tubular housing of electrically conductive material having inner walls defining an opening and first and second opposed open ends;
• an inner housing of electrically insulating material inserted into the tubular housing from at least one of the open ends thereof, the inner housing comprising at least one inner space configured to receive an electrical contact in a fixed relative position;
• and
• at least one electrical contact positioned in the inner housing and configured to be connected to an electrical cable;
• and
• a planar insulative connector body having an upper surface and an opposing lower surface, the upper and lower surfaces defined by a front edge, a back edge, and two longitudinal side edges, the upper surface including a plurality of longitudinal channels, each channel containing one of the plurality of electrical cable terminations, the front edge of the connector body having a plurality of openings for guiding the contact pins into the mating electrical cable terminations positioned within the channels,
• wherein at least two electrical cable terminations make electrical contact with a common stripline ground plate when the header and the electrical connector assembly are in a mated configuration.
