    • 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.
    • 偏转线圈包括中空的漏斗形锥形件,设置在锥形件的小孔部上的第一组绕线钩,设置在锥形件的大开口部上的第二组绕线钩, 包括第一至第n绕组的偏转线圈。 第一绕组束包括缠绕在第一组绕线钩的中心处的中心绕线钩上的导体束并且到第二绕线钩上。 第二绕组包括卷绕在中心卷绕钩上的导体束,在任一侧相邻的绕组钩和第二绕组钩。 第三和随后的绕组包括卷绕在中心绕线钩上的导体束,在任一侧相邻的多个绕线钩,并且到第二绕线钩上。 第一至第n绕组束以相同的方向卷绕到第一组绕线钩上,并在第一组绕线钩上对准。 第一至第n绕组束的排列顺序使得第一绕组束最靠近锥形件的小孔部分的端部,并且第n束从小型端部的端部离开, 锥形片的开口部分。
