  • Patent number: 6764324
    Abstract: A lever-type connector assembly has mating female and male connectors (10, 50). The female connector (10) has a lever (40) with a cam plate (41) and a resilient lock (46) that is deformable within the plane of the cam plate (41). The resilient lock (46) engages a receiving portion (33A) on the female connector (10) for holding the lever (40) at an initial position. The connector (50) has an unlocking rib (55) that deforms the resilient lock (46) out of engagement with the receiving portion (33A). As a result, the lever (40) can rotate for connecting the connectors (10, 50). Since the resilient lock (46) deforms in the plane of the cam plate (41), there is no need to provide space for deformation of the resilient lock (46) along a thickness direction of the cam plate (41).
