Deflection yoke

A deflection yoke apparatus, comprising:

• a saddle-type coil bobbin having a front end portion and a rear end portion;
• first guide grooves formed in an inner surface of said coil bobbin and extending across the front end portion and the rear end portion;
• at least one second guide groove formed at the outer surface of the front end portion;
• at least one third guide groove formed at the outer surface of the rear end portion;
• a multi-wire conductor wound around said saddle-type coil bobin to form a coil, the conductor having a substantially circular cross section and being routed through said first guide grooves, said at least one second guide groove, and said at least one third guide groove such that respective turns of the coil are sequentially layered in said first guid groove in a winding sequence order;
• wherein said at least one second guide groove and said at least one third guide groove have a width in a range of 1.0 to 1.5 times a diameter of said conductor and said conductor being laid substantially side by side in said first guide grooves, said at least one second guide groove, and siad at least one third guide groove.
