以下図面により本考案の実施例を説明する。 An embodiment of the present invention will be described below with reference to the drawings.
【０００７】 〔実施例１〕 図１は本考案の小型ソレノイドを示す半面破砕平面図であり、図１の（ａ）は 長さ３〜４ｍｍ、巾２ｍｍ、厚さ２ｍｍの寸法からなるサマリウムコバルト系永 久磁石３を使用した長さ１４〜１５ｍｍ、巾６〜９ｍｍ、厚さ２ｍｍ程度の寸法 の小型ソレノイドである。材質純鉄又はＳＰＣｅからなる長さ１０ｍｍ、巾６〜 ７ｍｍ、厚さ２ｍｍ程度の寸法のＵ字型ヨーク２内に永久磁石３が配置され、前 記Ｕ字型ヨーク２は巻線１のボビン６の内径部に圧入等により固定されている。 巻線用ボビン６は、ヨークと同じ材質で、高さ４〜５ｍｍ、巾６〜７ｍｍ、厚さ ２ｍｍ程度の台形をした可動ヨーク４とＵ字型ヨークの吸着面側の端部より射出 成型時に一体成型されたガイド５が可動ヨーク４外周部をおおう様に付けられて おり、可動ヨーク４の吸着、離反の際、ガイド内から可動ヨーク４が出ないよう に設定されている。[First Embodiment] FIG. 1 is a plan view of a crushed half surface of a small solenoid of the present invention. FIG. 1A shows a samarium cobalt having a length of 3 to 4 mm, a width of 2 mm and a thickness of 2 mm. It is a small solenoid that uses the permanent magnet 3 and has a length of 14 to 15 mm, a width of 6 to 9 mm, and a thickness of about 2 mm. A permanent magnet 3 is arranged in a U-shaped yoke 2 having a length of 10 mm, a width of 6 to 7 mm, and a thickness of about 2 mm, which is made of pure iron or SPCE, and the U-shaped yoke 2 is a bobbin of the winding 1. It is fixed to the inner diameter portion of 6 by press fitting or the like. The winding bobbin 6 is made of the same material as the yoke and is injection-molded from the end of the U-shaped yoke on the suction side of the trapezoidal movable yoke 4 having a height of 4 to 5 mm, a width of 6 to 7 mm, and a thickness of about 2 mm. At one time, a guide 5 which is integrally formed is attached so as to cover the outer peripheral portion of the movable yoke 4, and it is set so that the movable yoke 4 does not come out of the guide when the movable yoke 4 is attracted or separated.
【０００８】 〔実施例２〕 図１（ｂ）は永久磁石を使用しない小型ソレノイドの半面破砕平面図である。 Ｕ字型ヨーク２内に永久磁石が配置されておらずに、Ｕ字型ヨーク２は巻線１を 有するボビン６の内径部に圧入等により固定される。巻線用ボビン６は可動ヨー ク４とＵ字型ヨーク２の吸着面側の端部より射出成形時に一体成形されたガイド ５が可動ヨーク４の外周部を覆うように付けられており、可動ヨーク４の吸着、 離反の際ガイド５内から可動ヨーク４が出ないように設定されている。本考案の ガイドを設けることにより、可動ヨークが動作時の吸着面の位置ズレや装置内外 からの粉じん付着防止が可能となった。Example 2 FIG. 1B is a plan view of a half surface of a small solenoid that does not use a permanent magnet. No permanent magnet is arranged in the U-shaped yoke 2, and the U-shaped yoke 2 is fixed to the inner diameter portion of the bobbin 6 having the winding 1 by press fitting or the like. The winding bobbin 6 is attached to the movable yoke 4 and the U-shaped yoke 2 from the end on the suction surface side by a guide 5 integrally formed during injection molding so as to cover the outer peripheral portion of the movable yoke 4. It is set so that the movable yoke 4 does not come out of the guide 5 when the yoke 4 is attracted or separated. By providing the guide of the present invention, it is possible to prevent the displacement of the suction surface when the movable yoke operates and to prevent dust from adhering to the inside and outside of the device.
