Patent ID: 7470157

Claim:
A connector, comprising: a housing made of a resin and including at least one cavity for accommodating at least one terminal fitting, a resiliently deformable lock projecting into the cavity and a deformation space being defined on a side of the lock opposite the cavity, the lock being deformable into the deformation space during insertion of the terminal fitting into the cavity and resiliently returning towards the cavity for engaging the terminal fitting that has been inserted into the cavity; and a front retainer made of a resin and having a side wall insertable into the deformation space to prevent deformation on the lock away from the terminal fitting to retain the terminal fitting upon being mounted to a proper position on the housing; wherein: the front retainer includes a front wall, at least one locking arm projecting back from the front wall and formed with an engaging portion and the housing having at least one insertion space for receiving the locking arm, at least one lock being formed on a wall surface of the insertion space to face the locking arm substantially in a direction of thermal deformation resulting from the molding of the locking arm, the lock being configured for engaging the engaging portion and holding the front retainer on the housing.
