Abstract:
A half-fitting prevention connector, comprising:a first connector and a second connector fittable to each other, the connectors including housings, respectively;a spring member receivable in the housing of said first connector;a slider receivable in the housing of said first connector;a lock arm provided in the housing of said first connector, the lock arm having an engagement portion;wherein a half-fitted condition of the connectors is prevented by a resilient force of the spring member, and when said first connector is to be fitted relative to said second connector, the slider cooperates with the spring member to move between a lock position where the slider causes the lock arm to be engaged with the housing of said second connector and a non-lock position;a completely-retaining portion which retains the engagement portion of the lock arm, the completely-retaining portion being formed on the housing of said second connector; anda provisionally-retaining portion which retains the engagement portion with a retaining force smaller than that of the completely-retaining portion, the provisionally-retaining portion being formed on the housing of said second connector, wherein the completely-retaining portion and the provisionally-retaining portion are juxtaposed to each other in a direction of a width of the housing of said second connector, wherein the width direction is perpendicular to the engaging direction of said first and second connectors, andwherein, when the slider is moved to the lock position in a completely locked position, the slider deforms the lock arm in the direction of the width of the housing so as to displace the engagement portion of the lock arm from the provisionally-retaining portion of the completely-retaining portion.
