Coil support for an electromagnetic deflection unit

摘要

A hollow coil support for an electromagnetic deflection unit adapted to surround a part of a cathode-ray tube, the inside of the support carrying a deflection coil wound directly thereon, the support at each of its respective ends having a slotted annular member with groups of turns longitudinally extending from the slots in one annular member to the slots in the other annular member, and means provided between the ends of the support for locally supporting the longitudinal group of turns such that they are free from engagement with the inner surface of the support.
