Description

ソレノイドsolenoid
　本発明は、ソレノイドに関する。 The present invention relates to a solenoid.
　図９は、ソレノイドにおける吸引力ＦとストロークＳとの相対関係を示す一般的な説明図（グラフ）である。図９において、縦軸は、プランジャを吸引する力（引き込むための力）である吸引力Ｆを示し、単位は、［Ｎ］である。横軸は、プランジャの直線運動の移動量（移動距離）であるストロークＳを示し、単位は、［ｍｍ］である。 FIG. 9 is a general explanatory diagram (graph) showing the relative relationship between the suction force F and the stroke S in the solenoid. In FIG. 9, the vertical axis indicates a suction force F that is a force for attracting the plunger (force for pulling in), and the unit is [N]. The horizontal axis indicates the stroke S that is the movement amount (movement distance) of the linear motion of the plunger, and the unit is [mm].
　この図９に示すように、ソレノイドは、吸引力Ｆの値がストロークＳの値に対してほぼ二乗に反比例する。すなわち、ソレノイドは、ストロークＳの値が小さいと、吸引力Ｆの値が大きくなり、逆に、ストロークＳの値が大きいと、吸引力Ｆの値が小さくなる特性を有する。ストロークＳの値を小さくして吸引力Ｆの値を大きくするソレノイドとして以下の特許文献１がある。 As shown in FIG. 9, in the solenoid, the value of the suction force F is almost inversely proportional to the square of the value of the stroke S. That is, the solenoid has a characteristic that when the value of the stroke S is small, the value of the suction force F increases, and conversely, when the value of the stroke S is large, the value of the suction force F decreases. There is the following Patent Document 1 as a solenoid that decreases the value of the stroke S and increases the value of the suction force F.
　特許文献１のソレノイドは、コイル部材と、コイル部材のプランジャ挿通孔に挿通されたプランジャと、プランジャと支持板部との間に架け渡されるように配置された作動レバーと、から構成されている。特許文献１のソレノイドは、作動レバーの中間部がプランジャに力点軸により揺動可能に支持され、かつ、作動レバーの尾部が支点軸支持部である支持板部に支点軸により揺動可能に支持されている。特許文献１のソレノイドは、支点軸を支点と、力点軸を力点とし、作動レバーの先端部を作用点として、「てこの原理」を応用するものである。 The solenoid of Patent Document 1 includes a coil member, a plunger inserted through a plunger insertion hole of the coil member, and an operating lever arranged to be bridged between the plunger and the support plate portion. . In the solenoid of Patent Document 1, the intermediate portion of the operating lever is supported by the plunger so as to be swingable by a force shaft, and the tail portion of the operating lever is supported by the support plate portion which is a fulcrum shaft support portion so as to be swingable by the fulcrum shaft. Has been. The solenoid disclosed in Patent Document 1 applies the “leverage principle” with a fulcrum shaft as a fulcrum, a power point axis as a power point, and the tip of the operating lever as an action point.
　以下、図１０（Ｂ）、（Ｃ）を参照して、特許文献１のソレノイドと一般のソレノイドの「てこの原理」について説明する。図１０（Ｂ）、（Ｃ）中、符号「Ｐ１」は、支点である。「Ｐ２Ｂ」は、ソレノイドの通電遮断時状態で、プランジャの直線運動前の力点である。「Ｐ２Ａ」は、ソレノイドの通電時状態で、プランジャの直線運動後の力点である。「Ｐ３Ｂ」は、ソレノイドの通電遮断時状態で、プランジャの直線運動前の作用点である。「Ｐ３Ａ」は、ソレノイドの通電時状態で、プランジャの直線運動後の作用点である。「Ｓ２Ｂ」および「Ｓ２Ｃ」は、力点のストロークであって、プランジャの直線運動の移動量すなわちストロークＳである。「Ｓ３Ｂ」および「Ｓ３Ｃ」は作用点のストロークである。「Ｚ」はコイルの中心線であって、プランジャの直線運動の中心線である。 Hereinafter, with reference to FIGS. 10B and 10C, the “leverage principle” of the solenoid of Patent Document 1 and a general solenoid will be described. In FIGS. 10B and 10C, reference numeral “P1” is a fulcrum. “P2B” is a power point before the linear movement of the plunger in a state where the solenoid is de-energized. “P2A” is a power point after linear movement of the plunger in a state where the solenoid is energized. “P3B” is the operating point before the linear movement of the plunger in the state where the solenoid is de-energized. “P3A” is a point of action after linear movement of the plunger in a state where the solenoid is energized. “S2B” and “S2C” are strokes of the power point, and are the movement amount of the linear motion of the plunger, that is, the stroke S. “S3B” and “S3C” are strokes of the action point. “Z” is the center line of the coil and the center line of the linear movement of the plunger.
　図１０（Ｂ）に示す特許文献１のソレノイドは、作動レバーの尾部が支点Ｐ１であり、作動レバーの中間部が力点Ｐ２Ｂ（Ｐ２Ａ）であり、作動レバーの先端部が作用点Ｐ３Ｂ（Ｐ３Ａ）である。すなわち、特許文献１のソレノイドは、支点Ｐ１と作用点Ｐ３Ｂ（Ｐ３Ａ）とが、プランジャの直線運動の中心線Ｚであって、力点Ｐ２Ｂ（Ｐ２Ａ）を挟んで位置するものである。この特許文献１のソレノイドにおいて、支点Ｐ１から力点Ｐ２Ｂ（Ｐ２Ａ）までの距離を、支点Ｐ１から作用点Ｐ３Ｂ（Ｐ３Ａ）までの距離の２分の１とする。すなわち、支点Ｐ１から力点Ｐ２Ｂ（Ｐ２Ａ）までの距離と、力点Ｐ２Ｂ（Ｐ２Ａ）から作用点Ｐ３Ｂ（Ｐ３Ａ）までの距離とを、同等する。すると、力点のストロークＳ２Ｂは、作用点のストロークＳ３Ｂの２分の１となる。 In the solenoid of Patent Document 1 shown in FIG. 10B, the tail portion of the operating lever is the fulcrum P1, the middle portion of the operating lever is the force point P2B (P2A), and the tip of the operating lever is the action point P3B (P3A). It is. That is, in the solenoid of Patent Document 1, the fulcrum P1 and the action point P3B (P3A) are the center line Z of the linear motion of the plunger and are located with the force point P2B (P2A) in between. In the solenoid of Patent Document 1, the distance from the fulcrum P1 to the force point P2B (P2A) is set to one half of the distance from the fulcrum P1 to the action point P3B (P3A). That is, the distance from the fulcrum P1 to the force point P2B (P2A) is equal to the distance from the force point P2B (P2A) to the action point P3B (P3A). Then, the stroke S2B of the power point becomes half of the stroke S3B of the action point.
　一方、図１０（Ｃ）に示す一般のソレノイドは、プランジャの直線運動の中心線Ｚ上に力点Ｐ２Ｂ（Ｐ２Ａ）を有し、支点Ｐ１と作用点Ｐ３Ｂ（Ｐ３Ａ）とが、プランジャの直線運動の中心線Ｚであって、力点Ｐ２Ｂ（Ｐ２Ａ）に対して一側に位置するものである。この一般のソレノイドにおいて、支点Ｐ１から力点Ｐ２Ｂ（Ｐ２Ａ）までの距離と、支点Ｐ１から作用点Ｐ３Ｂ（Ｐ３Ａ）までの距離とを、同等する。すると、力点のストロークＳ２Ｃは、作用点のストロークＳ３Ｃと同等となる。 On the other hand, the general solenoid shown in FIG. 10C has a force point P2B (P2A) on the centerline Z of the linear motion of the plunger, and the fulcrum P1 and the action point P3B (P3A) are the linear motion of the plunger. The center line Z is located on one side with respect to the force point P2B (P2A). In this general solenoid, the distance from the fulcrum P1 to the force point P2B (P2A) is equal to the distance from the fulcrum P1 to the action point P3B (P3A). Then, the stroke S2C of the power point becomes equal to the stroke S3C of the action point.
　この結果、図１０（Ｂ）に示す特許文献１のソレノイドの作用点のストロークＳ３Ｂと、図１０（Ｃ）に示す一般のソレノイドの作用点のストロークＳ３Ｃとを同等とした場合。この場合においては、図１０（Ｂ）に示す特許文献１のソレノイドの力点のストロークＳ２Ｂすなわちプランジャの直線運動のストロークＳを、図１０（Ｃ）に示す一般のソレノイドの力点のストロークＳ２Ｃすなわちプランジャの直線運動のストロークＳに対して２分の１とすることができる。これにより、図１０（Ｂ）に示す特許文献１のソレノイドは、図１０（Ｃ）に示す一般のソレノイドに対して、吸引力を大きくすることができる。 As a result, the stroke S3B of the solenoid acting point of Patent Document 1 shown in FIG. 10B is equivalent to the stroke S3C of the general solenoid acting point shown in FIG. 10C. In this case, the stroke S2B of the solenoid power point shown in FIG. 10B, that is, the stroke S of the linear motion of the plunger shown in FIG. One half of the stroke S of the linear motion can be set. Thereby, the solenoid of patent document 1 shown to FIG. 10 (B) can enlarge suction force with respect to the general solenoid shown to FIG. 10 (C).

（実施形態１の作用の説明）
　この実施形態１に係るソレノイド１は、以上のごとき構成からなり、以下、その作用について説明する。 (Description of the operation of the first embodiment)
The solenoid 1 according to the first embodiment is configured as described above, and the operation thereof will be described below.
　まず、ソレノイド１の無通電時状態においては、図４に示すように、弾性部材３５のばね力により、作動部材３は、通常状態にある。この時の支点Ｐ１、力点Ｐ２Ｂおよび作用点Ｐ３Ｂは、図４、図１０（Ａ）に示す状態にある。 First, when the solenoid 1 is not energized, the operating member 3 is in a normal state by the spring force of the elastic member 35 as shown in FIG. At this time, the fulcrum P1, the force point P2B, and the action point P3B are in the state shown in FIGS. 4 and 10A.
　ここで、リード線２４を介してコイル２３に通電する。すると、コイル２３において磁気が発生する。この磁気により、フレーム２０、フロントフレーム２１、プランジャ２５およびフィクストコア２６が磁化されて、プランジャ２５がボビン２２中にコイル２３の中心線Ｚ方向に直線的に引き込まれる（図３中の実線矢印を参照）。 Here, the coil 23 is energized via the lead wire 24. Then, magnetism is generated in the coil 23. Due to this magnetism, the frame 20, the front frame 21, the plunger 25, and the fixed core 26 are magnetized, and the plunger 25 is linearly drawn into the bobbin 22 in the direction of the center line Z of the coil 23 (see the solid line arrow in FIG. 3). reference).
　すると、プランジャ２５の当接ピン２５３と、その当接ピン２５３が当接している作動部材３の当接部５０と、からなる運動変換部材５（力点Ｐ２Ａ、Ｐ２Ｂ）を介して、プランジャ２５の直線運動が作動部材３の回転運動に変換される。これにより、作動部材３は、回転中心線Ｃ１（支点Ｐ１）を中心として、図４に示す通常状態から図３に示す作動状態に、弾性部材３５のばね力に抗して時計方向に回転して（図３中の実線矢印を参照）、作動状態を維持する。また、作動部材３の一端部の作動部が作動して仕事をする。 Then, the movement of the plunger 25 via the motion conversion member 5 (power points P2A, P2B) including the contact pin 253 of the plunger 25 and the contact portion 50 of the operating member 3 with which the contact pin 253 is in contact. The linear motion is converted into the rotational motion of the actuating member 3. As a result, the operating member 3 rotates clockwise around the rotation center line C1 (fulcrum P1) from the normal state shown in FIG. 4 to the operating state shown in FIG. 3 against the spring force of the elastic member 35. (See the solid line arrow in FIG. 3) to maintain the operating state. In addition, the operating portion at one end of the operating member 3 operates to work.
　このように、ソレノイド１の通電時状態においては、図３に示すように、磁力により、作動部材３は、作動状態にある。この時の支点Ｐ１、力点Ｐ２Ａおよび作用点Ｐ３Ａは、図３、図１０（Ａ）に示す状態にある。 Thus, when the solenoid 1 is energized, the operating member 3 is in an operating state by the magnetic force, as shown in FIG. At this time, the fulcrum P1, the force point P2A, and the action point P3A are in the state shown in FIGS. 3 and 10A.
　そして、コイル２３への通電を遮断すると、磁力が消去され、弾性部材３５のばね復帰力により、プランジャ２５がボビン２２中からコイル２３の中心線Ｚ方向に直線的に突出する（図４中の実線矢印を参照）。これにより、作動部材３は、運動変換部材５（力点Ｐ２Ａ、Ｐ２Ｂ）を介して、回転中心線Ｃ１（支点Ｐ１）を中心として、図３に示す作動状態から図４に示す通常状態に、反時計方向に回転して（図４中の実線矢印を参照）、通常状態を維持する。また、作動部材３の一端部の作動部が作動を停止して仕事を停止する。 When the power supply to the coil 23 is cut off, the magnetic force is erased, and the plunger 25 projects linearly from the bobbin 22 in the direction of the center line Z of the coil 23 by the spring return force of the elastic member 35 (in FIG. 4). (See solid arrow). As a result, the operating member 3 moves from the operating state shown in FIG. 3 to the normal state shown in FIG. 4 around the rotation center line C1 (fulcrum P1) via the motion converting member 5 (force points P2A, P2B). Rotate clockwise (see solid arrow in FIG. 4) to maintain normal state. Moreover, the operation | movement part of the one end part of the operation member 3 stops operation | movement, and stops work.
　プランジャ２５のコイル２３の中心線Ｚ方向の直線運動の移動量が、図４、図１０（Ａ）に示すように、ストロークＳ２Ａ（Ｓ）となる。また、作動部材３の回転時においては、ガイド部２１１とガイド凸部３３とにより、作動部材３の回転がガイドされる。 The movement amount of the linear motion in the center line Z direction of the coil 23 of the plunger 25 is a stroke S2A (S) as shown in FIGS. Further, when the operating member 3 rotates, the rotation of the operating member 3 is guided by the guide portion 211 and the guide convex portion 33.
（実施形態１の効果の説明）

Mounting is possible, and the linear motion of the plunger 25 is changed to the rotational motion of the operating member 3 between the center line Z of the coil 23 and the rotational center line C1 of the mounting member 4 among the intermediate portions of the coil member 2 and the operating member 3. The motion converting member 5 to be converted is provided. Here, in the solenoid 1 according to the first embodiment, the rotation center line C1 is the fulcrum P1, the motion conversion member 5 is the force points P2A and P2B, and the operating part side of one end of the operating member 3 is the action points P3A and P3B.

Compared to the solenoid of Patent Document 1, the center line Z of the coil 23, that is, the center line Z of the linear movement of the plunger 25, can be positioned on the fulcrum P1 side. As a result, the solenoid 1 according to the first embodiment can further reduce the stroke S2A (S) of the linear motion of the plunger 25 and obtain a larger suction force F.
　例えば、図１０（Ａ）に示すこの実施形態１に係るソレノイド１は、図１０（Ｂ）に示す特許文献１のソレノイドと同様に、支点Ｐ１からプランジャ２５の直線運動の中心線Ｚまでの距離を、支点Ｐ１から作用点Ｐ３Ｂ（Ｐ３Ａ）までの距離の２分の１とする。すなわち、支点Ｐ１からプランジャ２５の直線運動の中心線Ｚまでの距離と、プランジャ２５の直線運動の中心線Ｚから作用点Ｐ３Ｂ（Ｐ３Ａ）までの距離とを、同等する。また、図１０（Ａ）に示すこの実施形態１に係るソレノイド１における作用点のストロークＳ３Ａと、図１０（Ｂ）に示す特許文献１のソレノイドにおける作用点のストロークＳ３Ｂと、を同等する。 For example, the solenoid 1 according to the first embodiment shown in FIG. 10A is a distance from the fulcrum P1 to the center line Z of the linear motion of the plunger 25, similarly to the solenoid of Patent Document 1 shown in FIG. Is half of the distance from the fulcrum P1 to the action point P3B (P3A). That is, the distance from the fulcrum P1 to the center line Z of the linear motion of the plunger 25 is equal to the distance from the center line Z of the linear motion of the plunger 25 to the action point P3B (P3A). Further, the stroke S3A of the action point in the solenoid 1 according to the first embodiment shown in FIG. 10A is equivalent to the stroke S3B of the action point in the solenoid of Patent Document 1 shown in FIG. 10B.

（実施形態２の作用の説明）
　この実施形態２に係るソレノイド１Ａは、以上のごとき構成からなり、以下、その作用について説明する。 (Description of operation of Embodiment 2)
The solenoid 1A according to the second embodiment is configured as described above, and the operation thereof will be described below.
　まず、ソレノイド１Ａの無通電時状態においては、図１４に示すように、弾性部材３５のばね力により、作動部材３Ａは、通常状態にある。この時の支点Ｐ１、力点Ｐ２Ｂおよび作用点Ｐ３Ｂは、図１０（Ａ）、図１４に示す状態にある。 First, when the solenoid 1A is not energized, the operating member 3A is in a normal state by the spring force of the elastic member 35 as shown in FIG. At this time, the fulcrum P1, the force point P2B, and the action point P3B are in the states shown in FIGS.
　ここで、コイル２３に通電すると、プランジャ２５Ａがボビン２２中にコイル２３の中心線Ｚ方向に直線的に引き込まれる（図１３中の実線矢印を参照）。これにより、運動変換ピン５１の一端部と、運動変換ピン５１の一端部が当接する当接面５２とからなる運動変換部材５Ａ（力点Ｐ２Ａ、Ｐ２Ｂ）を介して、プランジャ２５Ａの直線運動が作動部材３Ａの回転運動に変換される。 Here, when the coil 23 is energized, the plunger 25A is linearly drawn into the bobbin 22 in the direction of the center line Z of the coil 23 (see the solid line arrow in FIG. 13). Thereby, the linear motion of the plunger 25A is actuated via the motion converting member 5A (power points P2A, P2B) including the one end portion of the motion converting pin 51 and the contact surface 52 with which one end portion of the motion converting pin 51 contacts. It is converted into the rotational motion of the member 3A.
　この結果、作動部材３Ａは、回転中心線Ｃ１（支点Ｐ１）を中心として、図１４に示す通常状態から図１３に示す作動状態に、弾性部材３５のばね力に抗して時計方向に回転する（図１３中の実線矢印を参照）。作動部材３Ａの作動状態時の支点Ｐ１、力点Ｐ２Ａおよび作用点Ｐ３Ａは、図１０（Ａ）、図１３に示す状態にある。 As a result, the actuating member 3A rotates clockwise around the rotation center line C1 (fulcrum P1) from the normal state shown in FIG. 14 to the actuating state shown in FIG. 13 against the spring force of the elastic member 35. (See solid arrow in FIG. 13). The fulcrum P1, the force point P2A, and the action point P3A when the operating member 3A is in the operating state are in the states shown in FIGS.
　そして、コイル２３への通電を遮断すると、弾性部材３５のばね復帰力により、プランジャ２５Ａがボビン２２中からコイル２３の中心線Ｚ方向に直線的に突出する（図１４中の実線矢印を参照）。これにより、作動部材３Ａは、運動変換部材５Ａ（力点Ｐ２Ａ、Ｐ２Ｂ）を介して、回転中心線Ｃ１（支点Ｐ１）を中心として、図１３に示す作動状態から図１４に示す通常状態に、反時計方向に回転する（図１４中の実線矢印を参照）。プランジャ２５Ａのコイル２３の中心線Ｚ方向の直線運動の移動量が、図１０（Ａ）、図１４に示すように、ストロークＳ２Ａ（Ｓ）となる。 When the energization to the coil 23 is interrupted, the plunger 25A linearly protrudes from the bobbin 22 in the direction of the center line Z of the coil 23 by the spring return force of the elastic member 35 (see the solid line arrow in FIG. 14). . As a result, the operating member 3A moves from the operating state shown in FIG. 13 to the normal state shown in FIG. 14 around the rotation center line C1 (fulcrum P1) via the motion converting member 5A (force points P2A and P2B). Rotate clockwise (see solid line arrow in FIG. 14). The movement amount of the linear motion in the center line Z direction of the coil 23 of the plunger 25A is a stroke S2A (S) as shown in FIGS.
（実施形態２の効果の説明） (Description of the effect of Embodiment 2)

　すなわち、前記の実施形態１に係るソレノイド１は、プランジャ２５の当接ピン２５３と、その当接ピン２５３が当接している作動部材３の当接部５０と、からなる運動変換部材５（力点Ｐ２Ａ、Ｐ２Ｂ）を、取付部材４の回転中心線Ｃ１の支点Ｐ１とプランジャ２５の直線運動の中心線Ｚとの間に、位置させるものである。これに対して、この実施形態２に係るソレノイド１Ａは、運動変換ピン５１の一端部と、運動変換ピン５１の一端部が当接する当接面５２とからなる運動変換部材５Ａ（力点Ｐ２Ａ、Ｐ２Ｂ）を、取付部材４の回転中心線Ｃ１の支点Ｐ１とプランジャ２５Ａの直線運動の中心線Ｚとの間に、位置させるものである。 That is, the solenoid 1 according to the first embodiment includes the motion conversion member 5 (power point) including the contact pin 253 of the plunger 25 and the contact portion 50 of the operation member 3 with which the contact pin 253 is in contact. P2A, P2B) is positioned between the fulcrum P1 of the rotation center line C1 of the mounting member 4 and the center line Z of the linear motion of the plunger 25. In contrast, the solenoid 1A according to the second embodiment has a motion conversion member 5A (power points P2A, P2B) including one end portion of the motion conversion pin 51 and a contact surface 52 with which one end portion of the motion conversion pin 51 contacts. ) Between the fulcrum P1 of the rotation center line C1 of the mounting member 4 and the center line Z of the linear motion of the plunger 25A.
　この結果、この実施形態２に係るソレノイド１Ａは、前記の実施形態１に係るソレノイド１と同様の効果を達成することができる。すなわち、この実施形態２に係るソレノイド１Ａは、プランジャ２５Ａの直線運動のストロークＳ２Ａ（Ｓ）をさらに小さくして、さらに大きな吸引力Ｆが得られる。しかも、この実施形態２に係るソレノイド１Ａは、プランジャ２５Ａの直線運動を作動部材３Ａの回転運動に確実に変換させることができる。 As a result, the solenoid 1A according to the second embodiment can achieve the same effect as the solenoid 1 according to the first embodiment. That is, in the solenoid 1A according to the second embodiment, the stroke S2A (S) of the linear motion of the plunger 25A is further reduced, and a larger suction force F is obtained. Moreover, the solenoid 1A according to the second embodiment can reliably convert the linear motion of the plunger 25A into the rotational motion of the actuating member 3A.
