摘要： A deflection yoke for a cathode ray tube comprises a funnel shaped separator means 1a, 1b having a cylindrical neck portion 3 where a magnetic ring is attached. The magnetic ring is engaged with upward holding portions 33a, 33b and with downward holding portions 32a, 32b, which hold such magnetic ring. Root portions 33a3 and 33b3 of the downward holding portions 32a and 32b are substantially inflexible, where the inner circumference of the magnetic ring substantially contacts the root portions 33a3 and 33b3, and the root portions 33a3 and 33b3 restrict the position of magnetic ring from being disengaged from the protrusions 33a1 and 33b1 when the downward holding portions 33a and 33b are forced to disengage the magnetic ring.

摘要： 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.

摘要： 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.
