FERRITE CORE COUPLING DEVICE OF FLYBACK TRANSFORMER

摘要

PURPOSE: A ferrite core coupling device of a flyback transformer is provided to couple and fix easily a ferrite core without using an additional U-shaped clip by inserting an upper and a lower core into a core support portion. CONSTITUTION: A ferrite core(4) is installed in a flyback transformer case. The ferrite core(4) is divided into an upper core(2) and a lower core(3). One side of the ferrite core(4) is inserted into the inside of a bobbin(1) which is installed in the inside of the flyback transformer case. The other side of the ferrite core(4) is arranged at the outside of the flyback transformer case. A gap is formed between the upper and the lower cores(2,3). A core support portion(6) is installed at the outside of the flyback transformer case. A core insertion groove(5) is formed at the core support portion(6). An elastic fixing section(7) is formed on both inner wall faces of the core insertion groove(5). A fixing section support groove(8) is formed on both inner wall faces of the core support portion(6).
