Abstract:
A half-fitting prevention connector, comprising:a pair of connector housings fittable to each other; an elastic lock arm formed on one of the connector housings, the lock arm extending in a fitting direction of the connector housings; an engagement projection formed on the lock arm; a return spring contractibly supported on the lock arm along a longitudinal direction of the lock arm; an arm guide portion disposed on the other one of connector housings, the arm guide portion causing the lock arm to deform elastically toward an outer surface of the one of the connector housings in a half-fitted condition of the connector housings; a spring abutment portion formed on the other one of connector housings, the spring abutment portion abutting against one end portion of the return spring during connector fitting operation, so that the lock arm is elastically deformed toward the outer surface of the one of the connector housings while causing the return spring to resiliently deform, thereby producing a disengaging force urging the connector housings away from each other; and an arm retaining portion disposed on the other one of connector housings, the arm retaining portion retaining the engagement projection of the lock arm to lock the connector housings when the connector housings are completely fitted to each other after an elastic deformation of the lock arm is cancelled by the arm guide portion.
