ABSTRACT:
In a flyback transformer, an insulating cover is interposed between a main body casing and a focusing pack casing. A through-hole is formed through a ceramic resistor accommodated in the focusing pack casing. A fixing hole is formed through the insulating cover in a coaxial relationship with the through-hole. A slider is fixed on a rotatable knob for a variable resistor, which is supported on the focusing pack casing. One of two tongues of the slider is maintained in contact under pressure with a variable resistor of the ceramic resistor, and the other tongue is arranged coaxially with the fixing hole and is maintained in contact under pressure with a wire-shaped output terminal. The terminal is press-fitted in the fixing hole. Another flyback transformer is also disclosed, which comprises a cylindrical holder portion. An exposed portion of a conductor of a voltage output lead wire is formed in an L-shaped bent portion which is press-fitted in the holder portion, whereby the L-shaped bent portion is resiliently held at a basal portion thereof. A conductive rubber is connected to an output terminal. A free end portion of the conductor extends out from the holder portion into the conductive rubber.
