In this case, a sufficient insulation distance between the magnetic core and the winding can be ensured, and a coil bobbin with a simple shape can be used, so that the height can be suppressed and the product can be made small and inexpensive.
実施例
以下、本発明の実施例を添付の図面第１図〜第５図を用
いて説明する。Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings FIGS. 1 to 5.
第１図において、１１は合成樹脂の成形によって構成さ
れるコイルボビンで、このコイルボビン１１は端子１２
を植設し、側面にリード線溝１３を設けた端子板１４と
、この端子板１４の上面に角筒状の巻胴部１５とから構
成されている。In FIG. 1, 11 is a coil bobbin constructed by molding synthetic resin, and this coil bobbin 11 has a terminal 12.
The terminal board 14 has a lead wire groove 13 on its side surface, and a rectangular tube-shaped winding body 15 on the upper surface of the terminal board 14.
１６は先端にコイルボビン１１の巻胴部１５の先端をは
めこむ角状の凹部１７を設けた巻軸であシ、この巻軸１

軸１６の端面を巻始めとして巻線１８を巻回して、この
巻線１８の巻始めや巻終シの引出線を端子板１３のリー
ド線ガイド溝１３を通して端子１２に巻付けて半田処理
などで接続しコイル部品を完成させる。Reference numeral 16 denotes a winding shaft having an angular recess 17 in which the end of the winding trunk 15 of the coil bobbin 11 is fitted.
The winding trunk 16 of the coil bobbin 11 is fitted into the recess 17 of the coil bobbin 11, and by rotating the winding shaft 16, the winding 18 is wound starting from the end surface of the winding shaft 16. The lead wires at the beginning and end of winding No. 18 are passed through the lead wire guide groove 13 of the terminal plate 13, wound around the terminal 12, and connected by soldering or the like to complete the coil component.
また、第２図、第３図において、巻軸１６の凹部１７の
開口端にテーパ部１了＆を設ける構成とすることによシ
、巻線１８の端部をピラミッド形に積層していくことが
でき、巻線１８の端部でのくずれを防止することができ
る。In addition, in FIGS. 2 and 3, by providing a tapered portion 1 at the open end of the recess 17 of the winding shaft 16, the ends of the winding 18 are stacked in a pyramid shape. This makes it possible to prevent the ends of the winding 18 from collapsing.
さらにコイルボビン１１の巻胴部１６が円筒形の場合は
、第４図に示すように巻軸１６の凹部１７を円形とする
ことで対応できる。Furthermore, if the winding trunk 16 of the coil bobbin 11 is cylindrical, this can be accommodated by making the recess 17 of the winding shaft 16 circular, as shown in FIG.
上述のような方法によυ製作されたコイル部品をトラン
スに利用すると第５図に示すようになる。When a coil component manufactured by the method described above is used in a transformer, the result will be as shown in FIG.
すなわち、巻線１８を巻回したコイルボビン１１にＥＩ

ンスとなるが、磁心１９と巻線１８との絶縁距離は、巻
胴部１６の先端から巻軸１６の凹部１７の深さ分下方に
位置しているため十分確保できることになる。That is, EI is applied to the coil bobbin 11 around which the winding 18 is wound.
A transformer is created by incorporating a type or EF type magnetic core 19, but the insulation distance between the magnetic core 19 and the winding 18 is located below the tip of the winding trunk 16 by the depth of the recess 17 of the winding shaft 16. Therefore, it is possible to secure sufficient amount.
したがって、コイルボビン１１としては鍔のない分高さ
を低くでき、しかも、コイルボビ７１１の形状としてき
わめて単純にできるだめ、成形も容易となシコスト面で
も著しく有利となる。Therefore, the height of the coil bobbin 11 can be reduced due to the lack of a flange, and the shape of the coil bobbin 711 can be extremely simple, which is extremely advantageous in terms of cost since it can be easily molded.
