Abstract:
1. A connector with a housing having opposite front and rear ends and a cavity extending between the ends, a lock provided in the cavity, the lock being temporarily resiliently deformed by insertion of a terminal fitting into the cavity along an inserting direction from the rear towards the front of the housing, and the lock being resiliently restored to engage the terminal fitting when the terminal fitting reaches a proper depth, thereby preventing the terminal fitting from coming out, wherein: an outer wall of the terminal fitting substantially facing the lock has a locking projection projecting towards and engageable with the lock, the locking projection being arcuate in a transverse direction aligned transverse to the inserting direction, a recess is formed in a surface of the lock for sliding contact with the locking projection, the recess being arcuate in the transverse direction and being elongated along the inserting direction, and sliding-contact surfaces of the locking projection and the recess have substantially conforming shapes in the transverse direction for minimizing a required resilient deformation of the lock during insertion of the terminal fitting into the cavity.
