Connector and a method of assembling such connector
First Claim
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.

Abstract
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).
