US Patent 10218117 Electrical connector with assist lever

An electrical connector includes a first housing. A second housing is movable relative to the first housing. A lever is mounted on the first housing for relative rotational movement. The lever can move between a pre-stage position and a final position. The lever engages the second housing to move the second housing linearly between a pre-stage position and a seated position relative to the first housing. A lock on the first housing retains the lever in the final position relative to the first housing.
