Structure of Balance Coil of Deflection Yoke of Cathod Ray Tube

摘要

PURPOSE: A balance coil structure is provided to achieve improved work efficiency by permitting the starting part and ending part of the coil to be directly inserted into the circuit board. CONSTITUTION: A bobbin(53) has side plates(55,55') where protrusions(55a) are formed so as to fix a balance coil(50) to a circuit board(60). An intermediate plate(57) is arranged between the side plates. The intermediate plate has coil winding portions(56,56') formed at the left and right sides of the intermediate plate. The side plates have coil hanging portions(55b) with guide grooves(55c) for guiding a starting part(51a) and an ending part(51b) of the coil wound on the coil winding portions.
