A deflection yoke includes a coil, a base board, and a terminal. The terminal is mounted on the base board. The terminal extends from the base board. The terminal has a first portion and a second portion. The first portion of the terminal extends from the base board and has a substantially circular cross-section. The second portion of the terminal extends from the first portion thereof and has a cross-section with a corner. A lead extending from the coil is wound on the first and second portions of the terminal as a winding on the terminal. The winding has a first portion and a second portion. The first portion of the winding extends around the first portion of the terminal. The second portion of the winding extends around the second portion of the terminal. At least part of of the second portion of the winding is soldered to the second portion of the terminal while at least part of the first portion of the winding is non-soldered.

A deflection yoke 200 is comprised of a pair of separators 1, 1 formed in a funnel shape, having a large brim and a small brim. A first flange 1a is formed on the small brim, and a second flange 1b is formed on the large brim. A substrate 5 is held by at least one of the first flange and the second flange. A protective cover 26 is provided for protecting the substrate independently from the substrate by being held to the first flange and the second flange.

A mis-convergence correction device includes a first controlled coil unit, a second controlled coil unit, a controlling coil unit, and a coil holder. The first controlled coil unit includes first and second drum cores and a first controlled coil. Each of the first and second drum cores has circular flanges at its opposite ends respectively. The first controlled coil is provided on a portion of the first drum core between its flanges and also a portion of the second drum core between its flanges. The second controlled coil unit includes third and fourth drum cores and a second controlled coil. Each of the third and fourth drum cores has circular flanges at its opposite ends respectively. The second controlled coil is provided on a portion of the third drum core between its flanges and also a portion of the fourth drum core between its flanges. The controlling coil unit is located between the first and second controlled coil units. The coil holder accommodates the first and second controlled coil units and the controlling coil unit. The coil holder has first and second halves. The first half has a hold portion for each of the flanges of the first, second, third, and fourth drum cores. The hold portion has first and second inclined surfaces being non-parallel to each other. The first inclined surface contacts the related flange only at a first point as viewed in a cross-section of the related flange. The second inclined surface contacts the related flange only at a second point as viewed in the cross-section of the related flange. The first and second points are separate from each other.

The present invention provides deflection yoke devices used for a cathode ray tube. One of the deflection yoke devices of the present invention comprises a compensation coil having a bobbin formed with a hollow in which an internal thread is cut, a screw core forcibly fitting in the hollow of the bobbin and a damping material interposed between the bobbin and the screw core to prevent the displacement of the screw core when an external vibration or a shock is applied to the deflection yoke device. Another of the deflection yoke devices comprises a compensation coil having a bobbin formed with a cylindrical hollow in which an internal thread is cut, and a screw core fitting in the internal thread of the cylindrical hollow to allow the screw core to be displaced in a longitudinal direction of the cylindrical hollow, wherein the bobbin comprises first and second halves which are made by dividing the bobbin into two parts along a longitudinal direction of the bobbin, and a retainer section is provided on one of the first and second halves so as to extend to another of the first and second halves to allow the screw core to be pressed so that the displacement of the screw core due to vibration or shock is prevented.

A deflection yoke includes a bobbin having a cavity formed in the longitudinal direction of the bobbin, and an adjusting coil having a magnetic core on which a thread is cut. The core inserted into the cavity is slidable in the longitudinal direction of the bobbin. The core has a marker formed on only one of ends of the core in the longitudinal direction. The core has been inserted into the cavity from the one end formed with the marker or the other end. The marker is formed on only one of ends of the core before or after the thread is cut thereon.

A deflection yoke is comprised of a pair of separators 1a, 1b. A cylindrical neck 3 is formed on the pair of separators. Magnetic rings 7, 8, 10, 11 are installed on the neck. A spacer 19 is inserted between the magnet rings 8 and 10. A clamp band 5 is installed on the cylindrical neck, and fastens the deflection yoke to a neck of a cathode ray tube. The spacer has protuberances 19a, 19b. Projections 20a, 20b are formed on the pair of separators so as to engage with the protuberances for restricting rotation of the spacer.
