A deflection yoke includes a hollow funnel-shaped tapered piece, a first set of winding hooks provided on a small-aperture portion of the tapered piece, a second set of winding hooks provided on a large-aperture portion of the tapered piece, and a deflection coil including first through n-th winding bundles. The first winding bundle includes a bundle of conductor wound onto a center winding hook at the center of the first set of winding hooks and onto the second winding hooks. The second winding bundle includes a bundle of conductor wound onto the center winding hook, the winding hooks adjacent thereto on either side, and onto the second winding hooks. The third and subsequent winding bundles include bundles of conductors wound onto the center winding hook, a plurality of winding hooks adjacent thereto on either side, and onto the second winding hooks. The first through n-th winding bundles are wound onto the first set of winding hooks in a same direction, and aligned on the first set of winding hooks. The first through n-th winding bundles are arranged in an order such that the first winding bundle is closest to an end of the small-aperture portion of the tapered piece, and the n-th bundle is farthest from the end of the small-aperture portion of the tapered piece.

Deflection yoke

The saddle windings of the vertical deflection coils 31, 32 of a CRT are provided with external lines 11, 12 which establish distributed capacitances with the turns of the windings. Such lines present low impedance flow paths for unbalanced ringing currents induced in the vertical deflection coils by a high frequency horizontal deflection field, thus damping/dissipating the ringing currents and preventing their distortion of the displayed image.
