The present invention provides a coupling structure for mounting a core of a flyback transformer. The flyback transformer comprises a low-voltage bobbin, a housing, a lower core, an upper core and the coupling structure. The low-voltage bobbin comprises a winding shaft and a skirt. The winding shaft has an upper opening for receiving the upper core. The skirt has a lower opening for receiving the lower core. The lower opening defines an internal surface of the skirt. The coupling structure comprises at least one upper coupling device formed on the housing for mounting the upper core and at least one lower coupling device formed on the internal surface of the skirt for mounting the lower core. The upper core is mounted on the housing through the winding shaft by the upper coupling device. The lower core is mounted on the low-voltage bobbin through the skirt by the lower coupling device.
