A connector installation device wherein a connector has a stationary connector element and another connector element that is movable along an engagement axis with the stationary connector element and mates therewith. An insertion cam is movable perpendicular to the engagement axis of the mating connector elements. An insertion drive mechanism is interconnected with the insertion cam and is movable along an installation axis perpendicularly to the engagement axis. A drive force applied to the insertion drive mechanism translates the insertion cam along the installation axis into contact with an insertion drive surface of the insertion cam. Pressure against the insertion drive surface translates the movable connector element along the engagement axis toward the stationary connector element. The gentle easing of the engagement of the moveable and stationary connector elements allows sufficient opportunity for guidance mechanisms on the connector housings to orient the male pins for insertion into corresponding female receptacles.
