<p>PROBLEM TO BE SOLVED: To try to improve a work efficiency and to lower cost of manufacturing of a flyback transformer by simplifying the suppression of an unwanted radiation and to improve reliability by firmly fixing a ferrite core. SOLUTION: Ferrite core containers 30 and 31 are formed the fitted boundary face between a case 11 for a flyback transformer 11 coil and a case 12 for a high-voltage bleeder resistor. A focus cable 4 and a screen cable 4 are covered by ferrite core 7. The ferrite core 7 is worked in the ferrite core case 30 and 31, and the both cases 11 and 12 are fitted firmly each other, and the ferrite core 7 is fixed firmly in the semicylindrical inner hollow, formed by both the ferrite core case 30 and 31. The simple fitting of both the cases 11 and 12 with covering the cable 4 by the ferrite core 7 and working the ferrite core 7 into both the ferrite core cases 30 and 31 enables to suppressing an unwanted radiation from the cable 4. The ferrite core 7 is also firmly fixed.</p> |
