DEFLECTION YOKE

摘要

PURPOSE: A deflection yoke is provided to reduce a contact surface area between plural inner arms and an outer face of a coil separator by using a knurling side. CONSTITUTION: A deflection yoke includes a conical coil separator(10), a plurality of inner arms(20), and a knurling side. The conical coil separator is formed with a screen portion(11) of large diameter and a neck portion(13) of small diameter. Deflection coils are installed on an inner face and an outer face of the coil separator in order to deflect electron beams horizontally and vertically. The inner arms are adhered in a predetermined interval between the neck portion and the screen portion of the coil separator in order to convert the pin magnetic field to the barrel magnetic field. The knurling side is formed on the outer face of the coil separator in order to reduce a contact surface area between the inner arms and the outer face of the coil separator.
