A connector has a housing (20) with cavities (26) for receiving terminals (10). A lock (30) projects is provided in each cavity (26) and has a forwardly tapered locking surface (32) that is sloped to project more forward at the base than at the top. The connector also has a retainer (50) with a rest

A connector has a housing (20) with cavities (26) for receiving terminals (10). A lock (30) projects is provided in each cavity (26) and has a forwardly tapered locking surface (32) that is sloped to project more forward at the base than at the top. The connector also has a retainer (50) with a restricting plate (53) to prevent displacement of the locks (30) toward deformation spaces (36). Push-up protrusions (60) of the restricting plate (53) slip under the lower surfaces of the locks (30) as the retainer (50) is pushed towards a full locking position and push the locks (30) up towards cavities (26). A cam action of the sloped locking surfaces (32) pushes the female terminals (10) forward and against front walls (27).

1. A connector having a housing with opposite front and rear ends and at least one cavity extending between the front and rear ends and configured for receiving at least one terminal fitting, a resiliently displaceable lock provided on an inner wall of the cavity, the lock being configured for being resilient displaced by the terminal fitting during insertion of the terminal fitting into the cavity along an inserting direction, the lock resiliently returning when the terminal fitting is inserted a specified distance into the cavity so that a locking surface of the lock engages an engaging portion of the terminal fitting for locking the terminal fitting so as not to come out, the locking surface of the lock being slanted to form an obtuse angle with respect to the inserting direction, the obtuse angle being oriented so that portions of the locking surface projecting farther into the cavity are farther from the front end of the cavity when the lock is not deformed, a retainer mounted to the housing and configured for entering a deformation space for the lock to prevent the resilient displacement of the lock, whereby the obtuse angle of the locking surface enables the lock to urge the terminal fitting towards the front end of the cavity.2. The connector of claim 1, wherein the retainer includes at least one pushing portion for engaging the lock to displace the lock towards the terminal fitting upon entering the deformation space.3. The connector of claim 2, further comprising means for holding the retainer at a first position where the retainer is retracted from the deformation space to permit the resilient displacement of the locking and at a second position where the retainer is located in the deformation space.4. The connector of claim 1, wherein the lock comprises a disengagement operable portion for engaging a disengagement jig inserted into the housing.5. The connector of claim 4, wherein the disengagement operable portion is inclined with respect to the inserting direction and has a greater angle of inclination than the angle of the locking surface.6. The connector of claim 1, wherein, the locking surface defines an angle of inclination with respect to the inserting direction of between approximately 100° and approximately 150°.7. The connector of claim 6, wherein the locking surface defines an angle of inclination with respect to the inserting direction of between approximately 105° and approximately 140°.8. The connector of claim 6, wherein the locking surface defines an angle of inclination with respect to the inserting direction of between approximately 110° and approximately 135°.
