Description
【考案の詳細な説明】 （産業上の利用分野） 本考案は小型コイル特にノイズ防止用の小型トロイダ
ルコイルの構造に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a structure of a small coil, especially a small toroidal coil for noise prevention.
（従来の技術） 従来，小型モータなどのノイズ防止用の小型トロイダ
ルコイルは，第２図に示すように小型のトロイダルコア
１（例えば外径4mm,内径3mm,厚さ1mm）に巻線２を巻き
回し，巻線２の端部をコア１の直径方向にかつ同じ方向
に延ばした構造であった。(Prior Art) Conventionally, a small toroidal coil for noise prevention of a small motor or the like has a small toroidal core 1 (for example, outer diameter 4 mm, inner diameter 3 mm, thickness 1 mm) with a winding 2 as shown in FIG. The structure is such that the winding 2 is wound and the end of the winding 2 is extended in the diameter direction of the core 1 and in the same direction.
（考案が解決しようとする問題点） このような従来の小型トロイダルコイルは通常巻線の
太さが小さい（例えば直径0.3mm）ので延ばした端部が
変形し易く延在方向や間隔を一定に維持することが難し
く，またコアが割れ易いので穏やかに扱う必要があり，
そのために自動実装機による装着ができないという問題
があった。(Problems to be solved by the invention) Since such a conventional small toroidal coil usually has a small winding thickness (for example, a diameter of 0.3 mm), the extended end is easily deformed and the extending direction and the interval are constant. It is difficult to maintain, and the core is fragile, so it must be handled gently.
Therefore, there is a problem that the mounting cannot be performed by the automatic mounting machine.
（問題点を解決するための手段） 本考案の目的は自動実装機による装着が可能な小型ト
ロイダルコイルを提供することである。(Means for Solving Problems) An object of the present invention is to provide a small toroidal coil which can be mounted by an automatic mounting machine.

の開口溝６の両外側に植設されている。The insulating case 3 is a rectangular thick plate made of an insulating material, and is formed with an annular groove 4 having a depth sufficient for accommodating the toroidal coil on one side to the one short side, and the annular groove is formed in the annular groove. Is provided with a central cylinder 8 for holding and fixing the toroidal coil at its center, and a semi-cylindrical stand-off insulating projection 5 is provided at the central portion of the side face on the short side left with a thick wall. Shallow opening grooves 6 leading to the annular groove 4 on both sides of the piece 5.
Is protruding. Further, the case 3 has two pin terminals 7 (for example, a diameter of 0.6 mm) extending in the protruding direction of the insulating protrusion 5.
Are planted on both outer sides of the opening groove 6.

とができる。The toroidal coil as shown in FIG. 2 is fitted in the annular groove 4 of the insulating case 3 as described above, the end of the winding 2 is drawn out of the opening groove 6 to the outside of the case 3, and the end of the pin terminal 7 is removed. A small coil is completed by connecting with the solder. The inner peripheral surface of the toroidal coil is the central cylinder 8 of the annular groove 4.
If the end portion of the winding wire 2 is fixed to the pin terminal 7 by applying tension so as to contact the toroidal coil, the toroidal coil does not jump out of the case 3 in any posture of the small coil. Further, by providing the central column 8, it is possible to prevent the coil from jumping out of the insulating case 3 due to vibration or the like generated when the small coil is mounted on the automatic mounting machine.
このような小型コイルであるからトロイダルコイルに
触れないで取扱うことができ，ピン端子は変形しにくい
ので，コイル単体として自動実装機により扱うことがで
きる。またピン端子を十分に長くして小型コイルを一定

作り自動実装機に掛けることも容易である。With such a small coil, it can be handled without touching the toroidal coil, and the pin terminals are not easily deformed, so the coil can be handled as a single coil by an automatic mounting machine. It is also easy to make the pin terminals long enough to form a series of parts in which small coils are fixed to the mount tape at the ends of the pin terminals at regular intervals and to hang them on the automatic mounting machine.

組立および取扱いの自動化に極めて有効である。(Effect of the Invention) As described above, according to the present invention, the toroidal coil is automatically mounted because the pin terminals are housed in the insulating case, exposed to the outside, do not touch other articles, and do not pop out from the case. It is extremely effective for automating assembly and handling without damage when mounted by machine.
