Abstract
A deflection yoke for a color cathode ray tube has a cone part and a neck holder part. The neck holder part is attached on the outer circumferential surface of the neck of the CRT. The cone part can be rotated against the neck holder part and the neck holder part can be disconnected from the cone part. In the neck holder part, elastic bridges are equally arranged on the outer circumferential surface of a tubular plug. A plurality of ratchets are projected on the elastic bridges. Furthermore, teeth are equally arranged on the inner circumferential surface of the opening of the cone part. The teeth receive the tubular plug in order to mesh with the plurality of ratchets.
Claims5
A deflection yoke having a cone part and a neck holder part,
- wherein said neck holder part comprises:
- segmental pieces formed on one side of said neck holder part, said neck holder having another side defined by a flange;
- a tubular plug extending from the other side of said neck holder part;
- a plurality of ratchets equally arranged on the outer circumferential surface of said plug, and wherein said cone part comprises:
- a pair of separators symmetrically joined to each other and having a vertical and horizontal deflection coil on the inner and outer circumferential surface;
- and
- teeth equally arranged on the inner circumferential surface of an opening defined in said cone part for connecting with said plug of said neck holder part and meshing with said plurality of ratchets.
A deflection yoke comprising:
- a neck holder having at one side thereof a tubular plug, the tubular plug having a plurality of ratchets disposed around the tubular plug, and on another side thereof having means for attachment to a neck of a cathode ray tube;
- and
- a cone part having deflection coils and means for separating the coils, and means for defining an opening in an end of said cone part and having teeth on an inner circumference thereof for meshing with the ratchets of the neck holder.
