COIL BOBBIN-CUM-WOUND IRON CORE HOLDER FOR HIGH-FREQUENCY TRANSFORMER, AND HIGH-FREQUENCY TRANSFORMER

PROBLEM TO BE SOLVED: To provide a coil bobbin-cum-iron core holder for a high-frequency transformer that can hold an amorphous wound iron core on the assumption that the amorphous wound iron core is used as it is after annealing, and around which a primary coil and a secondary coil can be wound, and to provide a high-frequency transformer using the same.SOLUTION: A coil bobbin-cum-iron core holder for a high-frequency transformer consists of a synthetic resin frame body 1 comprising: a pair of iron core holding parts 6 and 6 holding an amorphous wound iron core 3 configured by annealing an amorphous magnetic steel strip wound a predetermined number of times in a cylindrical shape; and a pair of coupling parts 7 and 7 coupling the iron core holding parts at a predetermined interval. The frame body is divided at an intermediate part of both iron core holding parts; and two opposed pairs of divided iron core holding parts 6A and 6B comprise, at end parts, engaging parts 8 and 9 that can be coupled with each other in a state where the amorphous wound iron core are externally inserted. A coil holding part 10 for winding a coil strand for a high frequency wave is continuously formed outside both coupling parts and inside both iron core holding parts. 【課題】アモルファス巻鉄心を焼鈍後、そのままの状態で使用することを前提に、アモルファス巻鉄心を保持するとともに、一次コイルと二次コイルを巻回することが可能な高周波変成器用コイルボビン兼巻鉄心ホルダーを提供し、併せてそれを用いた高周波変成器を提供する。【解決手段】所定回数円筒状に巻回されたアモルファス磁性鋼帯が焼鈍されてなるアモルファス巻鉄心３を保持する一対の鉄心保持部６，６と、鉄心保持部を所定間隔を隔てて連結する一対の連結部７，７とを備えた合成樹脂製の枠体１からなり、枠体は両鉄心保持部の中間部で分割し、対向する二対の分割鉄心保持部６Ａ，６Ｂはアモルファス巻鉄心を外挿した状態で互いに連結可能な係合部８，９を端部に備え、両連結部の外側と両鉄心保持部の内部に、高周波用コイル素線を巻き付けるためのコイル保持部１０を連続して形成している。【選択図】図６
