Deflection unit for a color television display tube

A deflection unit for a color television display tube having a neck portion a display screen and a partly flared outer surface portion therebetween, said deflection unit comprising a field deflection coil, a line deflection coil, each of said deflection coils being formed by a pair of diametrically oppositely positioned coil portions, and an annular core of a magnetically permeable material surrounding at least the line deflection coil, each line deflection coil portion being in the form of a saddle coil and having conductors wound to produce first and second side members, a front end and a rear end which together define a window, said front end being in the form of a flange, the front ends of the coil portions of said line deflection coil, when said deflection unit is mounted on a display tube, being closer to the display screen than are the rear ends, with said front ends substantially surrounding a part of the flared portion of the display tube and the plane of the flange-like front ends being at an angle to the longitudinal axis of said display tube, and said first and second side members extending mainly parallel to the tube axis characterized in that the front ends of the line deflection coil portions together define a path whose length is greater than the length of a path around the flared portion of the display tube at which said front ends are intended to surround.
