Abstract
In a deflection yoke employing a saddle-shaped deflection coil of a bobbin-winding type, a fusion layer for fusing at least those wires of the coil disposed in proximity to each other is provided in each bent portion of the deflection yoke, whereby occurrence of corona at the bent portions can be effectively prevented.
Claims15
A deflection yoke comprising:
- a saddle-shaped deflection coil which is formed into a saddle-like shape by winding wires around a main body portion provided on a bobbin with bent portions around groove portions provided at both axial ends of said main body portion;
- wherein each of the bent portions formed by winding said wires around said groove portions has a fusion layer for fusing at least those of said wires disposed in proximity to each other.
The method of forming a fusion layer in a deflection yoke comprising:
- providing a generally saddle-shaped deflection coil with bent wire portions at the axial ends of said coil, the reference axis conforming to that of a CRT for which said coil is intended, and
- providing a fusion layer for at least said bent wire portions and, in turn, for at least those wires disposed in proximity to each other.
