Abstract

Deflection coil, obtained by bending into a part-cylindrical shape a coil comprising a plurality of glue-coated insulated wires simultaneously wound side by side without insulating intermediate layers, each wire forming a flat spiral.

Claims

1. A CRT deflection coil having a partially cylindrical shape comprising, a plurality of glue-coated insulated wires that are located side by side without an intermediate insulating layer therebetween so that each wire forms a flat spiral winding with an aperture and a plurality of turns, each of said apertures being substantially identical, said windings being mounted together with the apertures in alignment to form an integral deflection coil unit having a plurality of identical concentric flat spirals disposed side by side, and wherein the flat coil composed of the flat spiral windings has the shape of a partial cylinder.

2. A deflection coil as claimed in claim 1 wherein each of the wires that make up a spiral winding have a cylindrical cross-section, said wires being adapted to be connected together in a plurality of configurations.

3. A deflection coil as claimed in claim 1 wherein each of the wires that make up a spiral winding have a substantially identical cylindrical cross-section.
