ABSTRACT:
The present invention discloses that a primary and a secondary winding coil are respectively wound around the core and are separated by an insulating layer; and the secondary winding coil has a winding portion wound around the core through at least a circle to define two winding terminals, wherein each winding terminal of the winding portion is connected with an extending section extended to the outside of the transformer and is connected with an electricity connecting section at the rear end thereof. The electricity connecting section has plural pins electrically welded on a circuit board, thereby the extending section that is connected with a rectification switch and increases the contact areas with the air for achieving a heat-dispersing effect and the electricity connecting section are crossing connected between the secondary winding coil and the circuit board to save the space on the circuit board for arranging the secondary winding coil.
