Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案はインダクタを構成するトロイダルコアの巻線方法を含む構造に係り、 特に電線を巻回せずに構成したインダクタに関するものである。 The present invention relates to a structure including a winding method of a toroidal core that constitutes an inductor, and particularly to an inductor configured without winding an electric wire.

【0002】[0002]

【従来の技術】[Prior art]

従来のインダクタは、図3に示すようにトロイダルコア3への巻線は、銅線に 絶縁材をコーティングした電線13を使用し、1ターンずつ巻回しているが、特 にトロイダルコア3の軸方向の長さが長いものは、電線を複数回巻回する場合、 電線をトロイダルコアの内径内を貫通させる巻回作業が困難であった。更にトロ イダルコアの内径内で複数の電線が、交鎖したり、キンク(ひねられて出来る小 さな輪)が生じていた。 In the conventional inductor, as shown in FIG. 3, the winding to the toroidal core 3 uses the electric wire 13 in which a copper wire is coated with an insulating material and is wound one turn at a time. In the case where the length of the wire is long, it is difficult to wind the wire through the inside diameter of the toroidal core when the wire is wound multiple times. In addition, multiple wires crossed inside the inner diameter of the toroidal core, and kinks (small loops formed by twisting) occurred.

【0003】[0003]

【考案が解決しようとする課題】[Problems to be solved by the device]

従来のインダクタはトロイダルコアの内径内に1ターンずつ電線を貫通させる 作業を繰り返しおこない、電線の巻回作業に多くの時間を要していた。更にトロ イダルコアの軸方向の長さが長いトロイダルコアへの電線の巻回は、軸方向の中 心付近に電線のたるみ、ならびにキンクが生じ、内径内の電線の占有率が悪くな り、巻回数に限界があった。更に、電線のたるみは、巻層間の接触となり、レヤ ーショート(耐圧不良)の原因にもなっていた。一方、巻線の巻き始め、巻き終 わりの電線13の導体部がそのまま入出力端子となるので、該インダクタを装置 に組み込む作業中に折れ曲がり、作業性を悪くしていた。 In the conventional inductor, the work of passing the wire through the inside of the toroidal core one turn at a time was repeated, and it took a lot of time to wind the wire. Furthermore, when a wire is wound around a toroidal core with a long axial length of the toroidal core, the wire slacks and kinks occur near the center of the axial direction, and the occupancy rate of the wire within the inner diameter deteriorates. There was a limit to the number of times. Furthermore, the slack of the electric wire causes contact between the winding layers, which is also a cause of layer short circuit (poor pressure resistance). On the other hand, since the conductor portion of the electric wire 13 at the beginning and end of the winding serves as the input / output terminal as it is, it bends during the work of incorporating the inductor into the device, which deteriorates the workability.

【課題を解決するための手段】[Means for Solving the Problems]

本考案は、トロイダルコアの内径内に複数本の導体で形成された短冊状のフラ ットケーブルを遊貫し、該フラットケーブルの両端の導体の露出部を複数本の導 体パターンを形成したプリント基板の該導体パターンに結合し、該複数本の導体 並びに導体パターンが、該トロイダルコアを巻回して1本に連がる導体に構成し たインダクターにおいて、トロイダルコアの外径及び内径断面形状を矩形状に構 成し、該トロイダルコアの矩形状の内径の長尺方向に幅方向が位置するように該 フラットケーブルを遊貫させ、一方該トロイダルコアの外周辺に位置するプリン ト基板の両端のフラットケーブルと接続する配線ランド部には該プリント基板の 該トロイダルコアと接する面の反対面に溝をもつ端子台を構成する。 The present invention is a printed circuit board in which a strip-shaped flat cable formed of a plurality of conductors is loosely inserted into the inner diameter of a toroidal core, and a plurality of conductor patterns are formed on the exposed portions of the conductors at both ends of the flat cable. Of the toroidal core, wherein the plurality of conductors and the conductor pattern are wound around the toroidal core to form a continuous conductor. The toroidal core is formed into a shape, and the flat cable is allowed to penetrate so that the width direction is located in the longitudinal direction of the rectangular inner diameter of the toroidal core. A terminal block having a groove on the surface opposite to the surface of the printed circuit board that contacts the toroidal core is formed in the wiring land portion connected to the flat cable.

【作用】[Action]

本考案は、トロイダルコアへの巻線において、フラットケーブルとプリント基 板の導体によってコイルを形成し該コイルの巻き初め、巻き終わりに相当する部 分に端子台を構成したもので、1回の巻回作業で同時に複数回の巻線作業が出来 、作業性の向上、信頼性の向上が可能となる。 According to the present invention, a coil is formed by a conductor of a flat cable and a printed board in winding to a toroidal core, and a terminal block is formed at a portion corresponding to a winding start and a winding end of the coil. The winding work can be performed multiple times at the same time, improving workability and reliability.

【実施例】【Example】

図1は本考案による実施例を示す部品構成図である。フラットケーブル1がU 字状に形成してあり、両端は絶縁被膜を除去した左右各1本ずつの導体露出部7 及び複数の導体露出部8が露出している。図面上左右は対称である。フラットケ ーブル1の導体露出部7及び8のピッチ5と、プリント基板2の穴つき配線ラン ド11の隣接する穴ピッチ6は同じ寸法とし、導体露出部7、8は配線ランド1 1に容易に挿入できる構造並びに寸法である。配線ランド11は、両面でも、あ るいは、導体パターン12が形成された面だけでもよい。トロイダルコア3は外 径に比較し、軸方向の長さが長く、外径及び内径断面形状を矩形状に形成したも のである。プリント基板2の長尺方向寸法はトロイダルコア3の軸方向の長さよ り長くなっている。4は端子台であり、左右各1個が構成されている。フラット ケーブル1の巻き始め並びに巻き終わりに相当する左右各1本ずつの導体露出部 7は他の導体露出部8より長くしてある。端子台4は左右各1本ずつの導体露出 部7が貫通できる穴9、並びにプリント基板2の配線ランド11を収納する溝1 0が設けてある。 FIG. 1 is a component block diagram showing an embodiment according to the present invention. The flat cable 1 is formed in a U shape, and one end of each of the left and right conductor exposed portions 7 and a plurality of conductor exposed portions 8 from which the insulating coating is removed are exposed at both ends. The left and right sides in the drawing are symmetrical. The pitch 5 of the conductor exposed portions 7 and 8 of the flat cable 1 and the adjacent hole pitch 6 of the holed wiring land 11 of the printed circuit board 2 have the same size, and the conductor exposed portions 7 and 8 can be easily attached to the wiring land 11. It is a structure and dimensions that can be inserted. The wiring land 11 may be on both sides or only on the side where the conductor pattern 12 is formed. The toroidal core 3 has a longer axial length than the outer diameter, and the outer diameter and the inner diameter have a rectangular cross section. The lengthwise dimension of the printed circuit board 2 is longer than the axial length of the toroidal core 3. Reference numeral 4 denotes a terminal block, one on each of the left and right sides. The left and right conductor exposed portions 7 corresponding to the winding start and winding end of the flat cable 1 are made longer than the other conductor exposed portions 8. The terminal block 4 is provided with holes 9 through which conductor exposed portions 7 are provided on the left and right, and a groove 10 for accommodating a wiring land 11 of the printed circuit board 2.

【0007】 フラットケーブル1をトロイダルコア3の内径内に遊貫させた後フラットケー ブル両端の導体露出部7、8をプリント基板2の配線ランド11の穴に挿入する 。フラットケーブル1の1ターン目の導体露出部8はプリント基板2の最端部の 配線ランド11に接続され、プリント基板2の配線パターン12によって2ター ン目の巻き始めに相当する配線ランド11及び2ターン目の導体露出部8に接続 される。この関連をくり返すことで複数回の巻線がトロイダルコア3に巻回され たことになる。プリント基板2とフラットケーブル1の接続は平面状であるので 半田ディップ等の方法によりプリント基板2を1度に半田熔接処理できる。イン ダクタの巻き始めと巻き終わりに相当する端子は、端子台4の穴9をフラットケ ーブル1の導体露出部7を貫通させ、そのまま導体露出部7をインダクタの端子 としている。導体露出部7、8を半田熔接後はフラットケーブル1、プリント基 板2、トロイダルコア3並びに端子台4はそれぞれ樹脂系接着剤で接着固定し一 体化させる。After the flat cable 1 is loosely inserted into the inner diameter of the toroidal core 3, the conductor exposed portions 7 and 8 at both ends of the flat cable are inserted into the holes of the wiring land 11 of the printed circuit board 2. The exposed conductor portion 8 of the first turn of the flat cable 1 is connected to the wiring land 11 at the end of the printed circuit board 2, and the wiring pattern 12 of the printed circuit board 2 causes the wiring land 11 and the wiring land 11 corresponding to the start of winding of the second turn. It is connected to the exposed conductor 8 of the second turn. By repeating this relationship, multiple windings are wound around the toroidal core 3. Since the connection between the printed circuit board 2 and the flat cable 1 is flat, the printed circuit board 2 can be solder-welded at one time by a method such as solder dipping. The terminals corresponding to the winding start and winding end of the inductor are such that the hole 9 of the terminal block 4 penetrates the exposed conductor portion 7 of the flat cable 1 and the exposed conductor portion 7 serves as the inductor terminal. After the conductor exposed portions 7 and 8 are welded by soldering, the flat cable 1, the printed board 2, the toroidal core 3 and the terminal block 4 are bonded and fixed with a resin adhesive to be integrated.

【考案の効果】[Effect of device]

以上述べたごとく、トロイダルコアの内径内に遊貫したフラットケーブルの導 体とトロイダルコアの外側に位置するプリント基板の導体パターンを接続し端子 台を構成することによって、信頼性が高く巻線作業性の良いインダクタの提供が 可能となった。 As described above, by connecting the conductor of the flat cable that penetrates the inside of the toroidal core and the conductor pattern of the printed circuit board located outside the toroidal core to form the terminal block, the winding work is highly reliable. It has become possible to provide inductors with good performance.
