Connector and connector assembly

摘要

An auxiliary connector ( 14 ) has cavities ( 35 ) for receiving terminal fittings ( 13 ) and resilient locks ( 40 ) that deform in a deforming direction (DD) that extends along an arranging direction of the cavities ( 35 ). The locks ( 40 ) are configured for holding the terminal fittings ( 13 ) in the cavities ( 35 ). A retainer ( 39 ) is formed integrally with the auxiliary connector ( 14 ) via a hinge ( 75 ) at an opening edge of a retainer accommodating hole ( 73 ) in a side surface of the auxiliary connector ( 14 ) facing a direction intersecting the deforming direction (DD) of locks ( 40 ). The retainer ( 39 ) has locking protrusions ( 78 ) for redundantly locking the terminal fittings ( 13 ) in the cavities ( 35 ). The locking protrusions ( 78 ) of the retainer ( 39 ) are arranged at substantially the same positions for all cavities ( 35 ).
