Deflection unit for a cathode ray tube and method of manufacturing a saddle-shaped deflection coil

摘要

A deflection unit (4) includes a saddle-shaped deflection coil (30). The deflection coil includes at either the front or rear end a concave part having a left and right corner (41, 42) which define a line (43). The concave part is flanked at either side by adjacent portions (38, 39). It holds that: alpha>beta where alpha angle between a line (43) through the two corners (40, 41) of the concave part (40) and inner windings of the concave part (40), and beta is an angle between said line (43) and the inner windings at the outer side of a corner (41,42).
