Patent ID: 7575464

Claim:
A connector, comprising: a housing; a resiliently deformable lock arm formed on the housing, at least one projection projecting laterally from at least one lateral side of the lock arm; and at least one rib projecting on the housing at a position substantially adjacent to the lock arm, the rib being configured to define at least one clearance between a lateral end of the projection and the respective rib, the rib having a first thick portion adjacent the housing, a thin portion adjacent the first thick portion and opposed to the projection of the lock arm and a second thick portion adjacent the thin portion and spaced farther from the housing than the projection so that the clearance between the lateral end of the projection and the rib is configured to define a channel shape in rear view, the second thick portion having a slanted surface adjacent the thick portion and facing toward the projection for limiting outward displacement of the lock arm, a widthwise distance between a base end of an inner surface of the rib facing the lock arm and a lateral end of the projection being less than a clearance between the slanted surface of the second thick portion and the lateral end of the projection so that the inner surface at the base end of the rib contacts the lateral end of the projection to suppress loose lateral movements of the lock arm when the lock arm is deformed resiliently.
