Patent attributes
An opening (36) where two terminal fittings (50) are exposed is formed in a surface of a housing (20). A connection detecting member (70) is movable along the surface of the housing (20) between a retracted position and a detection position. The connection detecting member (70) has a shorting terminal mounting portion (85) into which a shorting terminal (60) is mounted. The shorting terminal (60) holds the terminal fittings (50) in a shorted state and releases the shorted state as the two housings (20, 100) are connected properly and the connection detecting member (70) reaches the detection position. The connection detecting member (70) is arranged at a height position overlapping a deformation space for a lock arm (40) between the housing (20) and the lock arm (40). The shorting terminal mounting portion (85) projects lateral to the lock arm (40) while extending along the surface of the housing (20).
