Electrical connectors with tapered terminal passageways

An electrical connector comprising:

• a housing having a housing first end, a housing second end, and a housing main body defining a recess, a recess base, a projection, a projection end, and a plurality of terminal passageways, the recess extending from the housing first end toward the housing second end and to the recess base, the recess base disposed a first distance from the housing first end, the projection extending from the recess base toward the housing first end and to the projection end;
• and
• each terminal passageway of the plurality of terminal passageways having an inner wall, the inner wall having an inner wall first end disposed at the projection end, an inner wall second end disposed between the projection end and the housing second end, an inner wall length extending from the inner wall first end to the inner wall second end, an inner wall first portion, an inner wall second portion, and an inner wall third portion, the inner wall first portion having a first inside diameter, the inner wall second portion having a second inside diameter, the inner wall third portion having a third inside diameter, the inner wall first portion extending from the inner wall first end toward the inner wall second end and to the inner wall second portion, the inner wall second portion extending from the inner wall first portion toward the inner wall second end and to the inner wall third portion, the inner wall third portion extending from the inner wall second portion to the inner wall second end, the first inside diameter being greater than the second inside diameter, the second inside diameter being greater than the third inside diameter, the inner wall tapering along a portion of the inner wall length extending from the inner wall first end toward the inner wall second end, the inner wall first portion and the inner wall second portion meeting at a first location along the inner wall length, the inner wall second portion and the inner wall third portion meeting at a second location along the inner wall length, the first location disposed a second distance from the housing first end, the second location disposed a third distance from the housing first end, the first distance being greater than the second distance, the third distance being greater than the second distance, the third distance being closer to the first distance than the second distance.
