  • Patent number: 5797758
    Abstract: A female connector for engagement with a male connector housing is provided. The female connector includes a female connector housing and a lever. The connector housing has a pair of axle parts formed to project from sidewalls. The lever is provided with a pair of bearing bores into which the axle parts are to be inserted. At a leading end of each axle part, a push projection is formed to extend perpendicular to the axle parts. Each bearing bore is provided with an insertion notch for allowing the push projection to pass. The insertion notch is positioned such that the push projection touches a solid part of the lever at its rotational beginning and end positions that the lever can occupy. Further, the insertion notch is also positioned such that the push projection passes above the insertion notch on the lever's rotational path to the end position. By this arrangement, the lever can be prevented from slipping out of the axle parts of the female connector housing.
