  • Passive locking cam and groove coupling
    Patent number: 6447016
    Abstract: A passive locking Cam & Groove female coupling, consisting of a locking latch mounted straddling the exterior of each cam arm attached to the coupling. The latch interlocks with a stop on the coupling body to provide a passive lock when the arm is closed. To open the cam arm, an intentional movement is applied to the latch so that the latch will pivot back and clear the stop thus allowing the cam arm to open.
