An electrical connector includes a first-housing, a second-housing, a slideable-skirt, and a terminal-lock. The second-housing is configured to mate with the first-housing along a longitudinal-mating-axis. The second-housing defines a slot in a top-side of the second-housing extending along a lateral-axis orthogonal to the longitudinal-mating-axis. The slideable-skirt is mounted to the second-housing and is moveable from a pre-stage position to a seated-position along the longitudinal-mating-axis. The slideable-skirt overlays a portion of a perimeter of the second-housing and defines cam-slots on a first-side and a second-side of the slideable-skirt. The terminal-lock is disposed within the slot and is moveable from a terminal insertion position to a locking position. The terminal-lock includes cam-posts extending from a first-end and a second-end of the terminal-lock disposed within the cam-slots. The terminal-lock moves from the terminal insertion position to the locking position as the slideable-skirt is moved from the pre-stage position to the seated-position.
