Patent ID: 7131869

Claim:
A connector comprising a housing made of resin and having opposite front and rear ends, the housing having at least one cavity extending from the rear end towards the front end for receiving a terminal fitting, a deformation space substantially adjacent the cavity and being defined partly by a wall facing towards the cavity, at least one lock having a base end unitary with the wall and a projecting end projecting angularly from the wall and partly into the cavity so that the deformation space is defined between the lock and the wall, the lock being temporarily deformable into the deformation space in response to forces exerted by inserting the terminal fitting into the cavity and being resiliently restorable to lock the terminal fitting when the terminal fitting reaches a proper depth, the wall including a bulge projecting towards the lock and into the deformation space from a location substantially adjacent the base of the lock, the bulge being inclined so that a bulging distance thereof gradually increases along a substantial length of the lock and towards the base end of the lock for ensuring a structural continuity of the wall, whereby the inclination of the bulge uses a of dead space between the wall and lock.
