An electrical connector, comprising: a first housing including a plurality of electrical terminals; a second housing: configured to mate with the first housing along a longitudinal mating axis, including a plurality of corresponding electrical terminals configured to mate with the plurality of electrical terminals of the first housing, and containing a slot in a top side of the second housing extending along a lateral axis orthogonal to the longitudinal mating axis; a slidable skirt: mounted to the second housing and moveable from a pre-stage position to a seated position along the longitudinal mating axis, overlaying a portion of a perimeter of the second housing, containing cam slots on a first side and a second side of the slidable skirt, and containing an actuation rib projecting from an inner surface of the slidable skirt; and a terminal lock: disposed within the slot, moveable from a terminal insertion position to a terminal locking position along a transverse axis orthogonal to the lateral axis and the longitudinal mating axis, inhibiting a longitudinal movement of the plurality of corresponding electrical terminals while in the terminal locking position, allowing the longitudinal movement of the plurality of corresponding electrical terminals while in the terminal insertion position, including a flexible lock, the flexible lock retains the terminal lock at the top side of the second housing, characterized in that the terminal lock includes cam posts extending from a first end and a second end of the terminal lock that are disposed within the cam slots of the slidable skirt, the terminal lock moves from the terminal insertion position to the locking position as the slidable skirt is moved from the pre-stage position to the seated position by the assembler as the cam posts travel in the cam slots, and wherein the actuation rib disengages the flexible lock and enables the terminal lock to move in the direction normal to the longitudinal mating axis when the slidable skirt is moved from the pre-stage position to the seated position. a first housing including a plurality of electrical terminals; a second housing: configured to mate with the first housing along a longitudinal mating axis, including a plurality of corresponding electrical terminals configured to mate with the plurality of electrical terminals of the first housing, and containing a slot in a top side of the second housing extending along a lateral axis orthogonal to the longitudinal mating axis;
