ABSTRACT:
The present invention discloses a color cathode ray tube and a deflection yoke. In accordance with the present invention the color cathode ray tube has a color cathode ray tube main body. The main body has a glass panel portion and a glass funnel portion connected to a rear part of the glass panel portion. An electron gun is located at the rear part of the color cathode ray tube main body. The color cathode ray tube also has a deflection yoke. The deflection yoke has a saddle shaped horizontal deflection coil located at a rear periphery of the color cathode ray tube main body, a saddle shaped vertical deflection coil located outside the saddle shaped horizontal deflection coil, and a core located outside the saddle shaped vertical deflection coil. A screen side flange portion of the horizontal deflection coil or the vertical deflection coil form a projection toward the screen side. The surface of the screen side flange portion of the horizontal deflection coil or the vertical deflection coil opposing the glass funnel portion of the color cathode ray tube conforms to the surface of the glass funnel portion.
