ABSTRACT:
A locking connector housing capable of insuring an inserting load necessary for locking, improving unlocking performance, and insuring reliability in the strength of a lock arm, is provided. Both lateral sides of a front end of a lock arm are supported by front support portions. The lock arm has a retaining projection, engageable with a retaining portion of a mating housing, and an unlocking portion. The front end support portions are disposed on a pair of protective walls erected on an upper wall surface of a housing. A rear end portion of the lock arm is folded back to form a band portion, with a tail end of the band portion being supported by a rear support portion on the upper wall surface of the housing. Reinforcing ribs are arranged on both lateral ends of the lock arm, each reinforcing rib being such that the height thereof is tapered from the front to the rear. The lock arm having the reinforcing ribs 14 and the band portion allows the housings to be engaged and locked, and requires only a small unlocking force.
