<p>PURPOSE:To reduce the variations of the quality of a title fly-back transformers by mounting a focus variable resistor on the upper surface of an insulating case, and connecting an anode lead wire and inserting an anode lead wire into a conductive rubber connected to a high voltage output part through the variable resistor. CONSTITUTION:A lid-shaped focus variable resistor 19 is placed on the upper part of a cylindrical insulating case 18. The focus variable resistor 19 is constructed by applying a resistor 23 on a ceramic board 22 and providing variable resistance thumbs 24, 25 where resistance is adjusted by trimming. Further, a cylindrical protrusion 29 for insertion of an anode lead wire 8 is provided. A resistor 23 of the focus variable resistor 19 is brought into contact with conductive rubber 32 attached to a diode 9, and the conductive rubber 32 is inserted into the cylindrical protrusion 29, and further the anode lead wire 8 is inserted into the conductive rubber 32 for connection. Hereby, variations of performance and so on are reduced.</p> |
