PURPOSE:To simplify the structure of a flyback transformer by providing a projection having a guide groove at a part of the circumference of a cylindrical case with a bottom and engaging a thick film printed resistor with this guide groove. CONSTITUTION:A projection a' is formed at a part of the circumference of a cylindrical case b' with a bottom, a guide groove 7 is formed on the inner surface of the projection a', a thick film printed resistor 5' is engaged with the guide groove 7, and high voltage coils 3-2 is connected via a rectifier 4-2 to one end of the resistor 5'. Then, high voltage coils 3-1, 3-2 and rectifiers 4-1, 4-2 are covered with insulating material in the case b'. Thus, the shape of the case can be simplified, thereby facilitating the mass production of the transformer. |
