  • Patent number: 5742218
    Abstract: In a flyback transformer, mounting pins for mounting components protrude from each of projecting jaw sections of a bobbin of a high-voltage coil section. A holder for the anode lead is positioned and secured to the bobbin, and the mounting pin which serves as the anode end of the high-voltage coil section is electrically connected to electrically conductive rubber or a connection fitting provided at one end of the holder. The flyback transformer comprises a connection pin having a male-contact shape protruding from one of the jaw sections. The connection pin is inserted into and held by the electrically conductive rubber or the connection fitting provided for the holder and is electrically connected to the mounting pin serving as the anode end of the high-voltage coil section.

  • Patent number: 4639663
    Abstract: A fly-back transformer to be used for use in the supply of a DC high voltage into a cathode-ray tube such as TV image receiving machine or the like. The ringing removing wire connected with the secondary winding through the distributed capacity with respect to the secondary winding to form a closed circuit of ringing current together with the secondary winding is connected in parallel to the primary winding through the DC resistance component, so that the ringing may be damped by the closed circuit.
