Lock-detecting Connector

A lock-detecting connector capable of surely detecting semi-connection or complete connection thereof is provided . The lock-detecting connector consists of a male connector having a pair of protecting walls on both sides of a locking arm, a female connector having an engaging projection to bend the locking arm and to engage the arm in a resiled state thereof and having a notched opening for receiving the protecting walls, and a lock-detecting member installed on a rear portion of the male connector, wherein the lock-detecting member has a pair of detecting arms abutting on the respective rear ends of the protecting walls, the detecting arms have respective outwardly-facing projections, and front corner-potions formed on both sides of the notched opening press the outwardly-facing projections inwardly. Slits for receiving the respective outwardly-facing projections are provided on the protecting walls, and upwardly-facing projections for abutting on the respective protecting walls are provided on the detecting arms. An interfering portion is provided on a lower portion of the rear end of the locking arm, and a pair of first-stop projections to abut on the locking arm in a bent state thereof and a second-stop projection to abut on the interfering portion are provided on the lock-detecting member. The locking-detecting member has a provisional engaging arm. Thus, a lock-detecting connector capable of surely detecting semi-connection or complete connection thereof can be realized.
