Half-fitting prevention connector

摘要

A half-fitting prevention connector (1) includes a pair of male and female connectors (2, 3) which are fittable to each other. A spring member (5) is received in the male connector (2) and prevents a half-fitted condition of the male and female connectors due to a resilient force thereof. A lock arm (10) is elastically-displaceably supported on a housing of one of the male and female connectors through interconnecting portions (30). The sum of the transverse cross-sectional areas of the interconnecting portions (30) is smaller than the transverse cross-sectional area of the lock arm (10) so that the whole of the lock arm (10) is not elastically deformed when canceling a fitted condition of the male and female connectors. When the male and female connectors are completely fitted to each other, the spring member (5) urges the lock arm (10) in such a direction that the lock arm (10) can retain the mating connector (3). <IMAGE>
