| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a transformer having a low loss which maintains the strength of a bobbin fitting portion and reduces the distance between an inner winding and an outer winding.SOLUTION: An outer bobbin 102 comprises an undivided unitary body, and the outer periphery of an upper flange portion 101b of an inner bobbin 101 or an inner winding 105 is smaller than the inner periphery of a lower surface of a hollow cylindrical portion 102d of the outer bobbin 102, and the clearance 200 between the upper flange portion 101b of the inner bobbin and the upper portion of the hollow cylindrical portion 102d of the outer bobbin is configured to cover the upper portion 103a of a cover 103.SELECTED DRAWING: Figure 3
【課題】ボビン嵌め合わせ部分の強度を保ち、内側巻線と外側巻線との距離を縮めた低損失なトランスを提供する。【解決手段】外側ボビン１０２は分割されていない一体物からなり、内側ボビン１０１の上鍔部１０１ｂあるいは内側巻線１０５の外周が、外側ボビン１０２の中空筒部１０２ｄ下面の内周より小さく、内側ボビン上鍔部１０１ｂと外側ボビン中空筒部１０２ｄの上部とのクリアランス２００を、カバー１０３の上部１０３ａが覆う構造とした。【選択図】図３ |
