Coil separator for deflection yoke

A deflection yoke for a cathode ray tube, comprising:

• a pre-formed deflection coil assembly wound by a coil winding machine in the shape of a saddle for deflection of an electron beam in horizontal and vertical directions;
• said coil assembly including a pair of horizontal deflection coils spaced vertically by vertical coils, said horizontal coils being wound annularly at upper and lower ends of said vertical coils, and
• a coil separator surrounding an outer periphery of said pre-formed coil assembly;
• said coil separator including:
• a screen portion of conical shape having a lower end with a band at said lower end, said screen portion coaxially surrounding an axis of said deflection coil assembly such that said screen portion surrounds said vertical coils of the deflection coil assembly in a position in which said band surrounds the horizontal deflection coil at the lower end of the coil assembly while the horizontal deflection coil at the upper end of the coil assembly extends above said screen portion,
• a neck portion prepared separately from said screen portion, said neck portion including a wire guiding portion and a yoke clamp fastening portion, and
• means for coaxially connecting said neck portion to an upper end of said screen portion such that said wire guiding portion surrounds said horizontal deflection coil of said deflection coil assembly which extends above the screen portion,
• said coil separator comprising left and right portions which are fitted on and assembled around said deflection coil assembly such that the horizontal deflection coil at the upper end of the deflection coil assembly extends above the screen portion.
