  • Patent number: 6737797
    Abstract: The invention relates to a cathode-ray tube having funnel sealed at one end to a faceplate panel with a viewing screen on an interior surface thereof, the funnel and the faceplate panel form an evacuated envelope, and a mask frame assembly supported within the envelope and in proximity to the screen. The cathode-ray tube includes a knee action circuit connector which electrically connects the internal conductive coating which is supported on an inside surface of the funnel. The knee action circuit connector is disposed between the exterior surface of the magnetic shield and the inside surface of the funnel and extends from the magnetic shield to form a curved first contact portion resiliently engaging the conductive coating of the funnel and a second contact portion extending from the curved portion and urged inwardly against the exterior surface of the internal magnetic shield thereby making electrical contact between the conductive coating and the internal magnetic shield.
