【考案の詳細な説明】
本考案は高周波用小型変成器等に使用されるトロイダル
磁心に関する。[Detailed Description of the Invention] The present invention relates to a toroidal magnetic core used in small high frequency transformers and the like.
従来、高周波用変成器等に使用される磁心は、一般に、
第１図に示すような形状のトロイダル磁心１である。Conventionally, magnetic cores used in high frequency transformers, etc. are generally
This is a toroidal magnetic core 1 having a shape as shown in FIG.
この磁心に巻線を施すには第２Ａ図に示すように、指で
磁心１を保持して行なうか、第２Ｂ図に示すように治具
９を使用して磁心１を保持して行なうかしている。To wind the magnetic core, either hold the magnetic core 1 with your fingers as shown in Fig. 2A, or use a jig 9 to hold the magnetic core 1 as shown in Fig. 2B. are doing.
しかし、変成器の高周波化および小型化に伴いトロイダ
ル磁心の小型化が必要となり、前記２つの巻線保持方法
では次のような多くの欠点が生じてきている。However, as the frequency of the transformer becomes higher and the size thereof becomes smaller, it becomes necessary to make the toroidal magnetic core smaller, and the above-mentioned two winding holding methods have many drawbacks as described below.
例えば、前者の場合、（１）磁心の保持が難しい。For example, in the former case, (1) it is difficult to hold the magnetic core;
（２）巻線が施された上から保持した場合、巻線がよご
れたり巻線が動いたりする。(2) If the wire is held from above the winding, the winding may get dirty or move.
（３）巻線途中で巻線がゆるみやすい。(3) The winding tends to loosen during winding.
また、後者の場合、（１）磁心の小型化に伴い治具９に
設けられた磁心保持部分６の磁心全体に対する占有率が
犬となり、巻線効率が劣下する。In the latter case, (1) as the magnetic core becomes smaller, the occupation ratio of the magnetic core holding portion 6 provided in the jig 9 to the entire magnetic core becomes smaller, and the winding efficiency deteriorates.
（２）巻線が施された上から保持すると、巻線を損傷す
る。(2) Holding from above the winding will damage the winding.
本考案の目的は上記欠点を除去した磁心を提供すること
にある。An object of the present invention is to provide a magnetic core that eliminates the above-mentioned drawbacks.
本考案の磁心は、磁心の外側円周部に少なくとも３箇所
の凹部を設けた構成を有している。The magnetic core of the present invention has a configuration in which at least three recesses are provided on the outer circumference of the magnetic core.
次に本考案について図面を参照して詳細に説明する。Next, the present invention will be explained in detail with reference to the drawings.
第３Ａ図および第３Ｂ図は本考案の一実施例を示す図で
ある。FIGS. 3A and 3B are diagrams showing an embodiment of the present invention.
図は巻線が施される前の磁心を示しており、凹部３，４
および５が磁心２の外側円周部に設けられている。The figure shows the magnetic core before winding, with recesses 3 and 4.
and 5 are provided on the outer circumference of the magnetic core 2.
第４Ａ図および第４Ｂ図は磁心２の保持方法を示す図で
あり、保持用ピン１０，１１および１２の先端部を磁心
２に設けられた凹部３，４および５に挿入することによ
り簡単に磁心２を保持することができる。4A and 4B are diagrams showing a method of holding the magnetic core 2, which can be easily performed by inserting the tips of the holding pins 10, 11, and 12 into the recesses 3, 4, and 5 provided in the magnetic core 2. The magnetic core 2 can be held.
このため、巻線を容易に施すことができ、巻線の動き、
ゆるみ、よごれおよび損傷がなくなる。Therefore, the winding can be easily applied, and the movement of the winding,
Eliminates looseness, dirt and damage.
また、ピン先端部の磁心全体に対する占有率が小さいの
で巻線効率もよい。Furthermore, since the pin tip portion occupies a small proportion of the entire magnetic core, the winding efficiency is also good.
以上、本考案には、巻線を容易に施すことができ品質お
よび巻線効率のよい変成器を製作できるという効果があ
る。As described above, the present invention has the advantage that it is possible to manufacture a transformer in which winding can be easily applied and the quality and winding efficiency are high.
