産業上の利用分野
本発明は各種民生、産業用電子機器に用いられるトラン
スに関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to transformers used in various consumer and industrial electronic devices.
従来例の構成とその問題点
一般にトランスに用いられるコイルボビンは安全規格に
規定された1次、2次巻線間の空間沿面距離を確保する

間に第3図に示す1次巻線3を巻線する。その後第3図
に示す絶縁テープ4を巻き付けさらに1次巻線の引出し
リード5と6と2次巻線7との空間、沿面距離を確保す
るため2次巻線用コイルスペーサ8を用いそのコイルス
ペーサ8の上に2次巻線7が巻線されている。Conventional structure and its problems Coil bobbins used in transformers generally have convex portions as shown in Figures 1 and 2 in order to ensure the spatial creepage distance between the primary and secondary windings stipulated by safety standards. 1 and 2 are provided, and a primary winding 3 shown in FIG. 3 is wound therebetween. Thereafter, the insulating tape 4 shown in FIG. A secondary winding 7 is wound on the spacer 8 .
以上のようなトランスの構造では2次巻線用のコイルス
ペーサ8が必要でありトランスの材料費アップ及び工数
アップになるとともにコイルの占積率も悪くなるという
欠点があった。The transformer structure as described above requires a coil spacer 8 for the secondary winding, which increases the cost of materials and man-hours for the transformer, and has the disadvantage that the space factor of the coil also deteriorates.
発明の目的
本発明は、1次巻線の巻始め引出しリード及び巻終わり
引出しリードを1次2次巻線間の空間・沿面距離確保の
だめのコイルボビンの凸起部の中にかくれるようなボビ

サが削除でき安価なトランスを提供するものである。Purpose of the Invention The present invention provides a bobbin in which a winding start lead and a winding end lead of a primary winding are hidden in a convex part of the coil bobbin to ensure space and creepage distance between the primary and secondary windings. With this structure, the coil spacer for the secondary winding can be omitted, providing an inexpensive transformer.
発明の構成
本発明は、巻始め及び巻終わシの引出しリードをピン端

用の凸起部に空間を設けるものでこの中に巻始め及び巻
終わりリードをかくれるように配線するものである。こ
のようにすれば引き出しリードは確実に2次巻線から安
全規格に規定された空間・沿面距離が確保できるため2
次巻線用コイルスペーサ−が削除できるため安価にトラ
ンスを製造することができる。Structure of the Invention The present invention provides a space in the coil bobbin and a convex part for securing creepage distance when winding the lead-out leads at the start and end of the winding around the pin terminal, and a space is provided in the convex part for securing the creepage distance. The wiring is to be hidden. In this way, the pull-out lead can secure the space and creepage distance specified in the safety standards from the secondary winding.
Since the coil spacer for the next winding can be eliminated, the transformer can be manufactured at low cost.
実施例の説明
以下本発明の一実施例を第4図〜6図によって説明する
。第4図、第5図の1aが凸起である。DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 to 6. 1a in FIGS. 4 and 5 is a convex portion.
この凸起は、ビン端子部9と一体のものであり、巻始め
及び巻終わりの引出しリードがビン端子に巻き付けられ
るように空間1oa、1obが設けられている。この空
間の中にかくれるように巻始め及び巻き終わり引出しリ
ード5,6を通しビン端子部に巻き付けられる。こうす
れば引き出しリード線は凸起部の中にかくれ第6図に示
す如く2次巻線7を巻線するとき従来例第3図のコイル
スペーサ−8を使用せずに1次2次巻線間の空間・沿面
距離が確実に確保することができる。This protrusion is integral with the bottle terminal portion 9, and spaces 1oa and 1ob are provided so that the lead-out leads at the beginning and end of winding can be wound around the bottle terminal. The winding start and winding end pull-out leads 5 and 6 are passed through the winding start and winding end so as to be hidden in this space and are wound around the bottle terminal portion. In this way, the lead wire is hidden inside the protrusion, and when winding the secondary winding 7 as shown in FIG. Space and creepage distance between lines can be ensured.
発明の効果
以上のように本発明は2次巻線用コイルスペーサ−を削
除できるため、スペーサ取付工数、スペーサー材料費の
低減及び巻線の占積率をアップすることができる。よっ
て安価なトランスを製造することができる。Effects of the Invention As described above, since the present invention can eliminate the coil spacer for the secondary winding, it is possible to reduce the spacer installation time and spacer material cost, and increase the space factor of the winding. Therefore, an inexpensive transformer can be manufactured.
