Deflection coil

Abstract

A deflection coil is provided which comprises a coil frame having a flared coil bobbin and guides provided at the front and rear ends of the coil bobbin and integrated therewith. The guide at the front end of the coil frame has a first plurality of circumferentially spaced coil winding insertion slots therein and the guide at the rear end of the coil frame has a second plurality of circumferentially based coil winding insertion slots therein. The first plurality of slots is greater than the second plurality of slots. The deflection coil further comprises a saddle-type coil along the inside surface of the coil frame which has a plurality of wires passing through predetermined coil winding insertion slots in the guide at the front and rear ends of the coil frame. The saddle-type coil winding has a distribution in the slots for producing a magnetic field having a strong pin-shaped field at the front end thereof and a barrel-shaped field at the rear end thereof.
