Abstract
An electromagnetic deflection unit for a cathode ray tube, comprising has at least one support (4) with a flange (8) at its narrow end (5), which has a tangential groove into which merge radial grooves (14). Two sets of deflection coils (18, 19) are wound directly onto the support (4). The turns thereof traverse the radial grooves (14), the turns of at least one set of deflection coils (18) being bent into the tangential groove. The radial grooves (14) have longitudinally extending portions (16), which are filled by the turns traversing them. The bottom portion (20) of the tangential grooves lie on the surface of an oval cylinder. The deflection unit has a high sensitivity, large axial sliding tolerance and permits correction of various kinds of deflection errors.
