Abstract

To enable a worker to be able to quickly and correctly verify that a slide-type cam member has moved into a closed position, making it possible for a housing of a mating connector to be moved into a completely engaged position, a resilient latch member, which extends toward a housing from an upper end of a side wall section of a cam member, is located on the cam member. A latch section, which has an aperture that receives a protrusion of the latch member, is located on an upper part of the housing. As the cam member is moved from a first position to a closed position, the latch member is depressed downward as a result of the protrusion moving along a second surface of the latch section. When the cam member has moved into the closed position, the protrusion is received by the aperture and, by virtue of the interrelationship, the latch member resiles to its original shape. When this occurs, a first surface of the latch member is brought into contact with the second surface of the latch section, thereby producing an audible sound signifying complete engagement between matable connectors.
