The present disclosure provides an electrical connector assembly having electrical connectors that are matingly connected and disconnected by operation of a lever actuator of one of the connectors. The lever is pivotally connected to one of the connectors and includes a drive gear at an end thereof. Each drive gear has gear teeth and a cam projection. The gear teeth of the drive gear mesh with gear teeth of a follower or mating gear pivotally mounted on the housing of the connector carrying the lever. The mating gear also includes a cam projection. The other connector has cam grooves positioned to engage with each cam projection such that movement of the lever causes drive gear to pivot all the cam projections to engage cam grooves and move the connectors to a fully mated condition.
