Connector for detecting incomplete engagement

摘要

One electrical connector 10 has no moving parts and the mating connector 20 has moving parts. This is made possible since connector locking projections 12 and detecting ribs 13, which serve as a first and second abutments respectively, are formed on the outer peripheral surface of one connector 10. The other connector 20, has a locking member 23 that fits with the locking projection 12, and a movable shutter 24 that overlies the locking member 23. The detecting rib 13, engages the shutter 24 which permits bending and thus latching of the locking member 23 only when the shutter 24 is to the retracted position. Once latched the shutter is movable to an advanced position to prevent the connectors being pulled apart.
