The invention relates to improved combination means for achieving positive placement of an internal electrical contactor in a cathode ray tube to effect and maintain a definitively oriented connection between an internal magnetic shield and a conductive coating disposed on the interior surface of the funnel portion of the tube envelope. Discrete portions of the shield are modified to form a pair of contactor positioning nubs and a cooperating indentation to contain a portion of the contactor in desired alignment therewith.

A cathode-ray tube has an internal magnetic shield and at least one contact spring attached to the shield. The shield includes a land with an outer edge and an inner edge. The spring includes two portions, an improved clasp portion attached to the shield at the land, and a contact leaf portion. The improved clasp portion includes a flat body with a reverse bend hook at a first end, and a latch and a catch at an end opposite to the first end. The hook engages the outer edge of the land, and the latch engages the inner edge of the land. The catch includes a bent end portion that forms an acute angle with the remainder of the catch. The bent end portion is positioned to engage the inner edge of the land if the spring is rotated about the hook. The leaf portion is connected to and extends from the latch.

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.
