【考案の詳細な説明】 本考案はトランス用絶縁紙に関する。
一般に１つのボビンにコイルを巻回する小型の
電源トランスにおいては、絶縁、耐電圧等を確保
する観点から１次巻線と２次巻線を形成する下巻
線と上巻線との間に絶縁部材が挿入されている。
しかして、従来、上下の巻線間に挿入されるこの
種の絶縁部材としては幅広の絶縁テープやツバを
有する中間絶縁ボビン等が用いられている。すな
わち、前者においては下巻線上に幅広の絶縁テー
プを巻く構造となつているが、この構造のものは
巻き付けの際、特にコイルの角部において引張る
力が加わるために絶縁テープはその両側がボビン
ツバ部から離れて内側にめくれ易く、よつて巻き
付け作業に注意を要すると共に、その部分におい
て上巻線のいわゆる線落ちが生じトランスの絶縁
不良、耐電圧不良等を招来する欠点がある。
また、後者の中間絶縁ボビンは、第１図に示す
ように、軸方向に２分割された２つの成形品から
なるボビンａ，a′から形成され、これらのツバを
有するボビンａ，a′を対向配置することによつて
下巻線の周囲を取り囲み下巻線と上巻線との絶縁
を確保するようになつている。したがつて、中間
絶縁ボビンによれば前者の絶縁テープを用いた場
合に比べ、ツバを有するため、線落ちが防止され
絶縁性は顕著に向上する利点はあるが、ボビン
ａ，a′を形成するための金型が必要となり、通常
この種の金型は高価であり、必然的に電源トラン
スのコスト高を招来する欠点がある。
本考案は上記の点に鑑み提案されたもので、安
価であると共に、作業性にも優れ、かつ良好な絶
縁性を有するトランス用絶縁紙を提供することを
目的とするものである。
以下、図面に沿つて本考案を説明する。
第２図および第３図は本考案の実施例を示すも
ので、同図中Ａは本考案にかかる絶縁紙で、この
絶縁紙Ａは、波形加工を施され、幅方向に向かつ
て延びるヒダが連続して多数形成され、かつ紙の
如き材質からなる絶縁材１と、この絶縁材１の片
面上に、その両側部１ａ，１ｂを除いて貼着され
る前記絶縁紙１の幅寸法より若干幅狭のプラスチ
ツクフイルムの如き材質からなる薄い絶縁材２と
により構成されている。
しかして使用にあつては、第４図イに示すよう
に、コイルボビン３の胴部上に巻回された下巻線
４の上に、同図ロに示すように、本考案にかかる
絶縁紙Ａを巻き付ければ良い。すなわち、絶縁紙
２の幅寸法はコイルボビン３の胴部の幅寸法と実
質的に等しく形成されており、コイルボビン３の
両端のツバ３ａ，３ｂ間に、絶縁紙Ａの背面、つ
まり絶縁紙２が貼着されていない他方の片面を当
接せしめて下巻線４上に絶縁紙Ａを巻き付けてゆ
く。この場合、絶縁紙Ａの両側部１ａ，１ｂは中
央部分に絶縁紙２が貼着されているため、その縁
によつてツバ３ａ，３ｂの内壁面に沿つて容易に
折れ曲がり、この両側部１ａ，１ｂは第１図に示
した中間絶縁ボビンａ，a′のツバとして作用する
ようになつている。また、絶縁紙Ａの巻き付けに
際して、絶縁紙Ａには連続したヒダが形成されて
いるため、下巻線４の外周に沿つて容易に曲げる
ことができ作業性が良好であると同時に、ヒダが
巻き付け時に作用する引張る力を吸収するので、
角部で絶縁材Ａの両側部１ａ，１ｂが内側にめく
れることがない。しかして、下巻線４上に絶縁紙
Ａを巻き付けた後は、ハ図に示すように、上巻線
５を巻回すれば電源トランスを構成することがで
きる。
第５図は下巻線４と上巻線５との間に絶縁紙Ａ
が挿入された状態を示す電源トランスの断面図で
ある。
以上の通り本考案によれば、波形加工を施した
絶縁材の片面に、その両側部を除いて絶縁材を貼
り合せて構成したから、 (イ) 単なる幅広の絶縁テープに比べ絶縁紙の両側
部がツバとして作用するため、巻き幅に対して
めくれたりすること等がなく、線落ちを防止し
得、よつて絶縁不良、耐電圧不良を起こすこと
がない。
(ロ) また、ヒダが形成されているため、下巻線上
の巻き付け作業性が良好である。
(ハ) 更に、成型品の中間絶縁ボビンのように金型
を何等要することがないため、その分コストダ
ウンを達成し得る。
等の効果を有する。
