US Patent 7448888 Connector and a connector assembly

A male terminal protection plate (30) is moved together with a female housing (50) in a direction separating from a receptacle (12), any further movement of the male terminal protection plate (30) in the separating direction can be prevented when a pair of locking projections (37) come into engagement with the upper edges of a pair of engaging grooves (18). Since the pair of locking projections (37) and the pair of engaging grooves (18) are arranged at the opposite sides of a cam pin (34), about which the male terminal protection plate (30) could be inclined, in a direction normal to moving directions of the male terminal protection plate (30), the inclination of the male terminal protection plate (30) can be prevented.
