<p>PURPOSE:To prevent short-circuiting between the ringingless parallel circuits of a flyback transformer and, at the same time, to simplify the connecting process of the parallel circuits. CONSTITUTION:In a flyback transformer provided with a low-voltage coil bobbin 4 wound with a primary coil, high-voltage coil bobbin 8 wound with a secondary coil in split winding, high-voltage diodes 17a-17f, and ringingless parallel circuits 6, expansion terminal sections 13b-13f from which terminal pins are protruded are provided in parallel with the DC-side terminal sections 12a-12f and AC-side terminal sections 11a-11f of the coil bobbin 8 and the circuits 6 are connected and fixed between the terminal sections 13b-13f in parallel with the diodes 17a-17f. As a result, the parallel circuits 6 do not come into contact and are not short-circuited with the terminals of the diodes 17a-17f nor the terminal sections of the coil bobbins and, at the same time, the manufacturing process of the ringingless parallel circuits can be simplified, because the circuits can be connected in the same process together with the diodes 17a-17f.</p> |
