【考案の詳細な説明】
本考案は一体威型した合成樹脂の弾力性乃至可撓性を利
用して分割型界磁磁石を簡単に組込み固定すべくなした
固定装置に関するものである。[Detailed Description of the Invention] The present invention relates to a fixing device that utilizes the elasticity or flexibility of an integrally molded synthetic resin to easily incorporate and fix a split field magnet.
従来に於いては円筒内にC型磁石を壁面に摺接し磁石と
磁石との間にU字形のばね材を介在してC型磁石を円筒
内に固定していたが軸方向の固定ができないためにばね
材以外にストッパ一部品をわざわざ別に用意しなければ
ならず部品が余分にかかると共にばね材を通し磁気短絡
が生じ有効磁束が減少したり又はね材に制約を受は軸方
向の固定が出来ないという欠点があった。Conventionally, the C-shaped magnet was fixed inside the cylinder by sliding it in contact with the wall and interposing a U-shaped spring material between the magnets, but it was not possible to fix it in the axial direction. Therefore, it is necessary to prepare a separate part for the stopper in addition to the spring material, which adds extra components and causes a magnetic short circuit through the spring material, reducing the effective magnetic flux or restricting the spring material from fixing it in the axial direction. The drawback was that it was not possible.
本考案はこれらの点に鑑みなされたもので以下に図示の
実例によりその内容について説明する。The present invention has been devised in view of these points, and its contents will be explained below using illustrated examples.
1は合成樹脂製の楕円リングでその短軸方向に剛体とし
ての一対のストッパー突起2を設けてありその巾tは、
C型磁石3及び4をケース本体5内に適性配置した際の
外側間隔中t1と内側間隔中t2との中間の巾を採用し
である。1 is an elliptical ring made of synthetic resin, and a pair of rigid stopper protrusions 2 are provided in the direction of its short axis, and its width t is as follows:
When the C-shaped magnets 3 and 4 are appropriately arranged in the case body 5, the width is set to be an intermediate width between the outer interval t1 and the inner interval t2.
即ちtl〉t>t2である。That is, tl>t>t2.
6は楕円リング1の長軸方向に設けた一対の位置決め突
起でケース本体5に穿った切欠部7に嵌合すべくなして
あり、円周方向への回動を止めるものである。Reference numeral 6 denotes a pair of positioning protrusions provided in the longitudinal direction of the oval ring 1, which are designed to fit into a notch 7 formed in the case body 5, and prevent rotation in the circumferential direction.
次に斜上の構成より成る本考案装置の組立て順序につい
て説明する。Next, the assembly sequence of the device of the present invention having a diagonal configuration will be explained.
先ずケース本体5内にC型磁石3及び4を適性配置する
。First, the C-shaped magnets 3 and 4 are appropriately arranged inside the case body 5.
然る後、楕円リング1の長軸側、具体的には位置決め突
起6を矢標A及びB方向に加圧変形し略円環状にしスト
ッパー突起2をC型磁石3.4の外側間隔中t1の近い
部分に挿入した後、加圧力を解く。Thereafter, the long axis side of the elliptical ring 1, specifically the positioning protrusion 6, is pressurized and deformed in the directions of arrows A and B to form a substantially annular shape, and the stopper protrusion 2 is inserted into the outer interval t1 of the C-shaped magnet 3.4. After inserting it near the area, release the pressure.
すると略円環状に加圧変形せしめられていた楕円リング
1は復元弾力により原形に復帰すべく作用しストッパー
突起2の巾tが内側間隔中t2より大であるためC型磁
石3,4を突つばる態様となりケース本体5内に固定す
ることとなる。Then, the elliptical ring 1, which had been pressurized and deformed into a substantially annular shape, acts to return to its original shape due to its restoring elasticity, and because the width t of the stopper protrusion 2 is larger than the inner interval t2, the elliptical ring 1 hits the C-shaped magnets 3, 4. It will be in a brim shape and will be fixed inside the case body 5.
尚、この際位置決め突起6はケース本体5の切欠部7内
に嵌合せしめる。At this time, the positioning protrusion 6 is fitted into the notch 7 of the case body 5.

にし軸方向への作用力に対し外れないように改善したも
のである。(Fig. 5) The embodiment shown in Figs. 8 to 10 is another embodiment, and is characterized in that a protrusion fitting hole 8 is bored in the case body 5, and the positioning protrusion 6 of the oval ring 1 is inserted into the case body 5. By doing so, the connection between the elliptical ring 1 and the case body 5 is made more secure, and it is improved so that it will not come off against the force acting in the axial direction.

正しい磁石の固定が可能となる等その実益する処多大な
ものがある。Therefore, in the present invention, the stopper protrusion 2 as a rigid body provided in the short axis direction of the elliptical ring is inserted into the gap that spreads radially between the C-shaped magnets 3 and 4 as seen diagonally above. The acting force always acts in the direction of the center, making it possible to securely fix the C-shaped magnet, and when inserting the stopper protrusion 2, it is inserted into the wide outer gap t1 in the gap, making the assembly process smooth and easy. Moreover, since a pair of positioning protrusions 6 are provided in the long axis direction of the integrally molded oval ring, rotation in the circumferential direction can be prevented, and the magnet can be fixed in the correct position. There are many things.
