コア１，３を挟持固定して成るものであった。Conventionally, this type of coil has a well-known structure shown in FIG. 1, in which two pot-shaped cores 1 and 3 are stacked one on top of the other, and a U-shaped upper holding metal fitting 5 is placed over the core 1 from above. A hole 7 is formed at the tip, and a protruding piece 11 shaped at the tip of the lower presser fitting 9 placed over the core 3 from below is hooked into the hole 7 of the upper fitting 5, and the upper and lower fittings 5 and 9 are stacked together. It was made by clamping and fixing the pot-shaped cores 1 and 3 together.
１３はボビン、１５はボビンに巻回されたコイルを、ま
た１７は上側金具５とツボ型コア１の間に介在する板バ
ネである。13 is a bobbin, 15 is a coil wound around the bobbin, and 17 is a leaf spring interposed between the upper metal fitting 5 and the pot-shaped core 1.
この構造の閉磁路型コイルは、上側金具５の穴７へ下側
金具９の突片１１を引掛けた後でなければ、重ね合せた
ツボ型コアが固定されない。In the closed magnetic circuit coil having this structure, the stacked pot-shaped cores are not fixed until the protruding piece 11 of the lower metal fitting 9 is hooked into the hole 7 of the upper metal fitting 5.
従って組立中にツボ型コア１，３が動き易く、コアの扱
いが煩雑になるばかりでなく、構成部品の損傷の原因に
もなっていた。Therefore, the pot-shaped cores 1 and 3 tend to move during assembly, which not only complicates handling of the cores but also causes damage to the component parts.
さらに動き易いツボ型コア１゜３に上下の金具５，９を
被せる作業もめんどうであった。Furthermore, it was troublesome to cover the easily movable pot-shaped core 1°3 with the upper and lower metal fittings 5 and 9.
本考案は、以上の欠点を改善した閉磁路型コイルを提供
するものである。The present invention provides a closed magnetic circuit coil that has improved the above-mentioned drawbacks.
以下図面を参照しつつ、本考案の一実施例を説明する。An embodiment of the present invention will be described below with reference to the drawings.
第２図は本考案の実施例を示す横断面図、第３図は同底
面図である。FIG. 2 is a cross-sectional view showing an embodiment of the present invention, and FIG. 3 is a bottom view of the same.
本考案は図示の様に、２個のツボ型コア１，３を互いに
被せ合う様に重ね合せてなる閉磁路型コイルにおいて、
そのツボ型コア１゜３を収納するケース１９の内側下部
に突起２１を２つ対向して形成し、そのツボ型コア１，
３の外周側面に縦溝２５を２つ対向して設け、前記突起

に収納したツボ型コア１，３を４５°程回転させること
により、ケース１９の突起２１でツボ型コア３の底面を
支持した閉磁路型コイルである。As shown in the figure, the present invention is a closed magnetic circuit coil in which two pot-shaped cores 1 and 3 are stacked so as to cover each other.
Two protrusions 21 are formed facing each other on the inner lower part of the case 19 that houses the pot-shaped core 1.
Two vertical grooves 25 are provided facing each other on the outer circumferential side of the case 19, and the grooves 25 of the pot type cores 1 and 3 are aligned with the protrusion 21, and the pot type cores 1 and 3 housed in the case 19 are rotated by about 45 degrees. Thus, it is a closed magnetic circuit type coil in which the bottom surface of the pot-shaped core 3 is supported by the protrusion 21 of the case 19.
第３図Ａはケース１９にツボ型コア１，３を収納した状
態を、同図Ｂはツボ型コア１，３を回転した後の底面図
を示している。FIG. 3A shows a state in which the pot-shaped cores 1 and 3 are housed in the case 19, and FIG. 3B shows a bottom view after the pot-shaped cores 1 and 3 have been rotated.
１３はボビン、１５はコイル、１７はケース１９内側天
井とツボ型コア１の上面間に介在し、ツボ型コア１，３
を下方に押圧する板バネで、前記ツボ型コア１，３は、
ケース１９内面天井と突起２１の間で弾性的に保持・固
定される訳である。13 is a bobbin, 15 is a coil, and 17 is interposed between the inner ceiling of the case 19 and the upper surface of the pot-shaped core 1, and the pot-shaped cores 1 and 3.
The pot-shaped cores 1 and 3 are plate springs that press downward.
This means that it is elastically held and fixed between the inner ceiling of the case 19 and the protrusion 21.
また、２３はツボ型コア１，３を回転させる為のドライ
バー溝で、２７は端子ピンを示す。Further, 23 is a driver groove for rotating the pot type cores 1 and 3, and 27 is a terminal pin.
本考案は、ケース１９の内側下部に突起２１を形威し、
その突起位置に損金する縦溝２５をツボ型コア１，３の
外周側面に設けることによって、突起２１が形成されて
いても障害とならずにケース１９内へ極めて簡単にツボ
型コア１，３を収納できる（第３図Ａ）。The present invention forms a protrusion 21 on the inner lower part of the case 19,
By providing a vertical groove 25 on the outer circumferential surface of the pot-shaped cores 1, 3 at the position of the protrusion, the pot-shaped cores 1, 3 can be inserted into the case 19 very easily without becoming an obstacle even if the protrusion 21 is formed. can be stored (Figure 3A).
そして、ツボ型コア１，３をある程度回転させておけば
、ケースの突起２１が障害となってツボ型コア１，３が
ケース１９より外れることはなく、ケース１９内に収納
される（第３図Ｂ）。If the pot type cores 1 and 3 are rotated to a certain extent, the pot type cores 1 and 3 will not come off from the case 19 due to the protrusion 21 of the case, and will be stored in the case 19 (the third Figure B).
ツボ型コア１．３を回転させる角度は任意であり、ケー
スの突起２１がツボ型コア３の溝２５以外の位置にくれ
ば、その底面を支持できる。The angle at which the pot-shaped core 1.3 is rotated is arbitrary, and if the protrusion 21 of the case is placed in a position other than the groove 25 of the pot-shaped core 3, the bottom surface of the pot-shaped core 3 can be supported.
ツボ型コア１，３の回転方法は種々の方法がある。There are various methods for rotating the pot-shaped cores 1 and 3.
例えば前述の如くツボ型コア１，３上面・底面にドライ
バー溝２３を形成することにより外部から容易に回転で
きる。For example, as described above, by forming the driver grooves 23 on the top and bottom surfaces of the pot-shaped cores 1 and 3, they can be easily rotated from the outside.
なお、ツボ型コアの回転は最少限下側に位置するツボ型
コア３のみで本考案の目的を達成できる。Note that the purpose of the present invention can be achieved by rotating the pot-shaped core only by rotating the pot-shaped core 3 located on the lower side.
所で、本考案に用いるケース１９は、導電性金属でも合
成樹脂でもよく、材質、形状を自由に決定できる。Incidentally, the case 19 used in the present invention may be made of conductive metal or synthetic resin, and the material and shape can be freely determined.
しかしツボ型コアを回転させる為に円筒状が適する。However, a cylindrical shape is suitable for rotating the pot-shaped core.
ケース１９に形成する突起２１の数・位置も任意である
。The number and position of the protrusions 21 formed on the case 19 are also arbitrary.
そしてその突起２１に掴合するツボ型コア１，３の外周
側面に溝２５を設ければよい。Then, grooves 25 may be provided on the outer peripheral surfaces of the pot-shaped cores 1 and 3 that engage with the protrusions 21.
また、本考案において、ツボ型コア１，３の固定をより
強固にする為には、ケース１９に収納したツボ型コア１
，３を回転した後、ケース１９下部にピッチ等を充填す
ればよい。In addition, in the present invention, in order to more firmly fix the pot-shaped cores 1 and 3, the pot-shaped cores 1 and 3 are housed in the case 19.
, 3, the lower part of the case 19 may be filled with pitch, etc.
以上説明した様に本考案の組立は、ツボ型コア１．３を
ケース１９内に次々に収納する作業から戒り、従来の様
にツボ型コア１，３が動くこともなく組立中の扱いが簡
単である。As explained above, the assembly of the present invention avoids the work of storing the pot-shaped cores 1 and 3 one after another in the case 19, and allows the pot-shaped cores 1 and 3 to be handled during assembly without moving as in the conventional case. is easy.
また収納するツボ型コア１，３やコイル１５等も組立中
ケース１９によって保護され損傷することもなくなる。Further, the pot-shaped cores 1, 3, coil 15, etc. to be stored are protected by the case 19 during assembly and will not be damaged.
さらに上下の金具５，９による組立と異なり、収納した
ツボ型コア１，３をちょっと回転させるだけで、ツボ型
コア１，３をケース内に支持・固定でき、作業が簡単に
なるばかりでなく下側の金具を必要としないので部品点
数を減少でき、コスト低減を図ることができる。Furthermore, unlike assembly using the upper and lower metal fittings 5 and 9, the pot-shaped cores 1 and 3 can be supported and fixed within the case by simply rotating the stored pot-shaped cores 1 and 3, which not only simplifies the work but also Since a lower metal fitting is not required, the number of parts can be reduced, and costs can be reduced.
