ABSTRACT:
A flexible coil winding structure of a flyback transformer is disclosed, which comprises a magnetizable core at the center portion, a first conductor line pattern and a second conductor line pattern at both sides, and a pair of flexible insulator sheets at both sides for substantially insulating the overall coil winding structure and protecting it from its surroundings while in service. The first and second conductor line patterns are arranged so as to provide the coiled circuit pattern. A pair of insulating strips are provided between the magnetizable core and the first and second conductor line patterns. Also, the coil winding structure includes an electrical connection for connecting the upper portions and the lower portions of the first and second conductor line patterns so that they provide the coiled circuit pattern. The electrical connection may be provided by soldering or welding, etc. A manufacturing process of the flexible coil winding structure is also disclosed.
