High-voltage transformer

The utility model relates to a high-voltage transformer, which is applied to the cold cathode lamp tube and comprises a winding tube, two wire bodies which are respectively winded on the winding tube and two iron cores which are arranged on the winding tube in a matching mode. Wherein, two wire bodies respectively wind the winding tube to define out a primary side and a secondary side, and two wiring feet are arranged on the secondary side of the winding tube to make the wire bodies of the secondary side connected, providing the two cold cathode lamp tubes on the back end to connect. The wiring feet are respectively arranged at the starting winding position and the winding position of the last end of the wire body winded on the secondary side of the winding tube, avoiding the interference generated by the existing high-voltage transformer which arranges the wire body of the secondary side in a loop mode. Because the distance between the two wiring feet is enlarged, the high-voltage transformer eliminates the electric arc effect and is more practical.
