摘要:
A coil-winding frame body for deflection yoke coil, includes: a straight portion formed as a neck side; a trumpet-shaped curved surface portion spreading outward from the end of the straight portion toward a head side; and a plurality of flanges formed on the inner face of the body for defining a plurality of coil-winding grooves and walls, and each of the grooves is elongated from the neck side to the head side and into which a wire ribbon will be wound in layers. In the thus constructed coil-winding frame body, at least one of the plurality of coil-winding grooves includes a main groove in the straight portion which in turn is divided in the curved surface portion into a plurality of branch grooves, and the plurality of branch grooves are arranged such that an extended line from an inner side wall of each the branch groove converges at a common end point on the straight portion of an inner side wall of the main groove, whereas an extended line from an outer side wall of each of the branch grooves converges at a common end point on the straight portion of an outer side wall of the main groove.
