Electrical connector including heat dissipation holes

An electrical connector assembly comprising:

• an electrical connector comprising:
• a housing comprising
• a housing body defining a first outer perimeter, and
• a shroud defining a second outer perimeter and having a first surface and a second surface opposite the first surface in a mating direction;
• a plurality of electrical conductors supported by the housing body, the electrical conductors defining respective mounting ends that extend through a mounting interface of the housing body and are configured to mount to a substrate, and mating ends that are configured to mate with respective ones of a plurality of complementary electrical conductors of a second electrical connector in the mating direction;
• and
• at least one heat dissipation hole extending through the shroud and comprising a first end open at the first surface and a second end open at the second surface, wherein:
• the second outer perimeter is disposed outboard with respect to the first outer perimeter along a direction perpendicular to the mating direction such that at least a portion of each of the mating ends is surrounded by the second outer perimeter and the at least one heat dissipation hole is unobstructed by the second electrical connector when the electrical connector is mated to the second electrical connector;
• and
• at least a portion of the first end is disposed at a location outboard of the first outer perimeter and inboard of the second outer perimeter;
• a substrate;
• a first electrical trace carried by the substrate, wherein the substrate carries at least one first mounting location at the first electrical trace;
• and
• a second electrical trace different than the first electrical trace and carried by the substrate, wherein the substrate defines at least one second mounting location at the second electrical trace,
• wherein a portion of the first electrical trace is aligned with a portion of the second electrical trace along a direction perpendicular to the mating direction, and the at least one first mounting location is aligned with the at least one second mounting location along a common centerline that is oriented along the mating direction, and
• wherein the at least one first mounting location is configured to physically and electrically connect to at least one mounting end of a first one of the electrical conductors, and the at least one second mounting location is configured to physically and electrically connect to at least one mounting end of a second one of the electrical conductors.
