  • Patent number: 3947793
    Abstract: A multi-layer toroidal deflection yoke includes a flared ferrite core and grooved ring members respectively disposed at the large and small diameter ends of the core to determine the position of several layers of toroidally wound conductor turns which form the deflection windings. The large diameter ring member includes radially extending tabs forming conductor receiving pockets therebetween. Each pocket has a width less than the combined diameters of the generally side-by-side conductor turns wound in the pocket. Each pocket includes first and second conductor seat portions at different heights so that the first conductor turn is retained in the first seat portion by a first tab and the second seat, the second conductor turn is retained by the first conductor turn and a second tab and subsequent conductor turns are similarly retained.
