Abstract
Abstract A connector having a pair of opposed housings capable of being fitted to and detached from each other, guide slits formed in one of the housings, driven pins provided on the other housing, and a lever rotatably attached to the one of the housings and capable of engaging with the driven pins. The housings are fitted to or detached from each other by an operation of rotating the lever. Mating engagement holes and projections capable of engaging with each other when the housings are normally fitted are provided on one of the housings and the lever, and other engagement holes and projections for fitting confirmation are provided on the other housing and the lever. Therefore the operator can easily confirm the locked state of the lever with eye. Also, the facility with which the connector is designed and manufactured is improved.
