Reference numeral 45 denotes a thin plate-shaped mounting plate, a notch 46 having an opening at the upper end is formed in the center, and a pair of mounting holes 47 and a pair of holes 48 are formed on both sides of the notch 46. .
【０００４】 次に、このような構成の電磁石装置の組立方法を説明する。先ず、コイル２３ が巻回されたコイルボビン１５をヨーク２の側面部３、４間に嵌合固定する。こ のとき、中空部１９と穴９とが連通するとともに、水平面部３ａが中空部１９の 下端に位置する。次に、水平面部３ａ側からアーマチュア１０の支持板４０を中 空部１９内に挿入して、アーマチュア１０を中空部１９内に嵌挿し、支持板４０ の先端部を穴９から突出させる。Next, a method of assembling the electromagnet device having such a configuration will be described. First, the coil bobbin 15 around which the coil 23 is wound is fitted and fixed between the side surface portions 3 and 4 of the yoke 2. At this time, the hollow portion 19 and the hole 9 communicate with each other, and the horizontal surface portion 3 a is located at the lower end of the hollow portion 19. Next, the support plate 40 of the armature 10 is inserted into the hollow portion 19 from the side of the horizontal surface 3a, the armature 10 is inserted into the hollow portion 19, and the tip of the support plate 40 is projected from the hole 9.
【０００５】 切欠部２６を支持板４０の凹部４１に嵌挿させながら、固定板２５を側面部４ に沿って上方から下方に摺動させて、凹部４１を凹部４４に係合させ、ダボ８に 穴２８を嵌合させて位置決めすることにより、固定板２５を側面部４に仮固定す る。しかるのち、取付板４５を側面部４に沿って下方から上方に摺動させて、ダ ボ８に穴４８を嵌合させて位置決めするとともに、前記切欠部２６と切欠部４６ とで支持板４０を支持することにより、この切欠部２６と４６とを支点としてア ーマチュア１０を揺動自在に支持する。ねじ３６を穴４８、２８を挿通し、ねじ 孔７に螺合させることにより、取付板４５と固定板２５とを側面部４に取付ける 。While inserting the notch 26 into the recess 41 of the support plate 40, the fixing plate 25 is slid downward from above along the side surface portion 4 to engage the recess 41 with the recess 44, and the dowel 8 The fixing plate 25 is temporarily fixed to the side surface portion 4 by fitting and positioning the hole 28 in the. After that, the mounting plate 45 is slid upward from the lower side along the side surface part 4 to fit the hole 48 into the dowel 8 for positioning, and the notch portion 26 and the notch portion 46 support the support plate 40. The armature 10 is swingably supported by using the notches 26 and 46 as fulcrums. The mounting plate 45 and the fixed plate 25 are attached to the side surface portion 4 by inserting the screw 36 into the holes 48 and 28 and screwing the screw 36 into the screw hole 7.
【０００６】 最後に、コイルスプリング４２をフック部１１ａ、１７ａ間に掛け渡すことに より、アーマチュア１０の吸引部１１にヨーク２の水平面部３ａから離間する方 向の揺動習性が付与される。 このように組み立てられた電磁石装置においては、コイル２３に通電されると 、ヨーク２と、アーマチュア１０との間に磁気回路が形成され、アーマチュア２ の吸引部１１が、コイルスプリング４２の付勢力に抗して、水平面部３ａに吸引 される。Finally, by wrapping the coil spring 42 between the hook portions 11 a and 17 a, the suction portion 11 of the armature 10 is provided with a swinging habit in a direction away from the horizontal surface portion 3 a of the yoke 2. In the electromagnet device assembled in this way, when the coil 23 is energized, a magnetic circuit is formed between the yoke 2 and the armature 10, and the attraction portion 11 of the armature 2 acts on the biasing force of the coil spring 42. Against it, it is sucked to the horizontal plane portion 3a.
【０００７】[0007]
上述した従来の電磁石装置においては、図６に詳細に示すように、アーマチュ ア１０に固定した支持板４０を固定板２５の切欠部２６と取付板４５の切欠部４ ６とで挟持し、この点Ｂを揺動支点した構造としているため、アーマチュア１０ の揺動動作の際に、摩擦による揺動動作のロスを防止するために、アーマチュア １０の下端部とヨーク２の側面部４の穴９の下端面とが接触しないように、アー マチュア１０とヨーク４との間にあらかじめエアーギャップＣを設けている。こ のため、従来の電磁石装置においては、磁気効率が悪化し、アーマチュアの動作 時間が遅れ、消費電力も多くなるといった問題点があった。 In the conventional electromagnet device described above, as shown in detail in FIG. 6, the support plate 40 fixed to the armature 10 is sandwiched between the notch portion 26 of the fixing plate 25 and the notch portion 46 of the mounting plate 45. Since the structure in which the point B is a fulcrum fulcrum, the lower end of the armature 10 and the hole 9 of the side surface part 4 of the yoke 2 are prevented in order to prevent a loss of the oscillating motion due to friction during the oscillating motion of the armature 10. An air gap C is previously provided between the armature 10 and the yoke 4 so as not to contact the lower end surface of the. For this reason, the conventional electromagnet device has problems that the magnetic efficiency is deteriorated, the operation time of the armature is delayed, and the power consumption is increased.
【０００８】 したがって、本考案は上記した従来の問題点に鑑みてなされたものであり、そ の目的とするところは、磁気効率を向上させた電磁石装置を提供することにある 。Therefore, the present invention has been made in view of the above-mentioned conventional problems, and an object thereof is to provide an electromagnet device having improved magnetic efficiency.
【０００９】[0009]
この目的を達成するために、本考案に係る電磁石装置は、対向する一対の側面 部を有し、一方の側面部に切欠きを設け、他方の側面部に水平面部を形成した断 面略コ字状のヨークと、対向する一対の鍔が形成され、これら鍔間を連結する中 空状の胴部にコイルが巻回され、前記ヨークの側面部間に取付けられたコイルボ ビンと、このコイルボビンの胴部内に嵌挿され一端側が前記ヨークの水平面部に 対向し、他端側がヨークの切欠きに臨み、この他端側を揺動支点としてヨークに 支持されたアーマチュアとからなる電磁石装置であって、前記一方の側面部の表 面に固定板を取付け、この固定板に前記アーマチュアの端縁を突き当てるととも に、一方の側面部の切欠きの端縁をアーマチュアの揺動支点とする。 In order to achieve this object, an electromagnet device according to the present invention has a pair of side faces facing each other, one side face is provided with a notch, and the other side face is formed with a horizontal plane portion. A character-shaped yoke and a pair of flanges facing each other are formed. A coil is wound around a hollow body connecting the flanges, and a coil bobbin mounted between the side surfaces of the yoke, and the coil bobbin. Of the armature supported by the yoke with the other end facing the notch of the yoke and the other end facing the horizontal surface of the yoke, and the other end of the armature being supported by the yoke. Then, a fixing plate is attached to the surface of the one side surface, the edge of the armature is abutted against the fixing plate, and the edge of the notch of the one side surface is used as the swinging fulcrum of the armature. .
【００１０】[0010]
本考案によれば、常に、アーマチュアとヨークとが揺動支点で接触した状態を 保持するので、磁気効率が低下することがない。 According to the present invention, since the armature and the yoke are always kept in contact with each other at the swing fulcrum, the magnetic efficiency is not lowered.
【００１１】[0011]
以下、本考案の一実施例を図に基づいて説明する。図１は本考案に係る電磁石 装置の分解斜視図、図２は同じく断面図、図３は要部断面図である。これらの図 において、従来技術と同一の構成あるいは同等の構成については、同一の符号を 付し詳細な説明は省略する。ヨーク２の側面部４には、中央には、上端が開口し た切欠部５が、上端両側部には、段部６が、それぞれ形成されている。１２はア ーマチュア１０の先端側にかしめ固定された薄板状の板ばねで、先端に向かって 上方に傾斜した傾斜部１３が形成され、傾斜部１３の先端側両側部には一対の凹 部１４が凹設されている。 An embodiment of the present invention will be described below with reference to the drawings. 1 is an exploded perspective view of an electromagnet device according to the present invention, FIG. 2 is a sectional view of the same, and FIG. 3 is a sectional view of essential parts. In these drawings, the same or similar configurations as those of the conventional technique are designated by the same reference numerals, and detailed description thereof will be omitted. On the side surface portion 4 of the yoke 2, a notch portion 5 having an open upper end is formed in the center, and step portions 6 are formed on both side portions of the upper end. Reference numeral 12 denotes a thin plate-shaped leaf spring that is caulked and fixed to the tip end side of the armature 10. An inclined portion 13 is formed so as to incline upward toward the tip end, and a pair of concave portions 14 are formed on both side portions on the tip end side of the inclined portion 13. Is recessed.
【００１２】 コイルボビン１５の一方側の鍔１６の上端両側部には、コイル端子２１が植設 された端子取付部２０と凸部２２が一体形成されている。固定板２５の中央には 、上端が開口した切欠部２６が設けられている。この切欠部２６の下端までの高 さＨは、前記ヨーク２の側面部４の切欠部５の下端までの高さｈよりもやや大に 形成されている。３０は薄板状のばね部材で形成された保持板で、略中央に打ち 抜き孔３１が穿設され、この打ち抜き孔３１内に逆Ｔ字状の保持部３２が保持板 ３０に連設されており、この保持板３０の下端両側部側には、凹部３３が形成さ れている。３４は取付孔、３５は穴である。On both sides of the upper end of the collar 16 on one side of the coil bobbin 15, a terminal mounting portion 20 in which a coil terminal 21 is implanted and a convex portion 22 are integrally formed. At the center of the fixed plate 25, a notch 26 having an open upper end is provided. The height H of the cutout portion 26 to the lower end is slightly larger than the height h of the side surface portion 4 of the yoke 2 to the lower end of the cutout portion 5. Reference numeral 30 denotes a holding plate formed of a thin plate-shaped spring member. A punching hole 31 is formed substantially in the center, and an inverted T-shaped holding portion 32 is continuously provided to the holding plate 30 in the punching hole 31. A recess 33 is formed on both sides of the lower end of the holding plate 30. Reference numeral 34 is a mounting hole, and 35 is a hole.
【００１３】 次に、このような構成の電磁石装置の組立方法を説明する。先ず、コイルボビ ン１５を、凸部２２を段部６に係合させて位置決めしながら、ヨーク２の両側面 部３、４間に嵌合させて固定する。しかるのち、固定板２５の穴２８を側面部４ のダボ８に位置決めし、この状態を保持しながら、アーマチュア１０の支持板１ ２側からコイルボビン１５の中空部１９内に、支持板１２が固定板２５の切欠部 ２６内に臨むまで挿入する。このとき、固定板２５の切欠部２６の下端部が側面 部４の切欠部５の下端面から上方に突出しているので、アーマチュア１０の前端 部が、固定板２５の裏面に突き当たる。Next, a method of assembling the electromagnet device having such a configuration will be described. First, the coil bobbin 15 is fitted and fixed between the side surface portions 3 and 4 of the yoke 2 while the convex portion 22 is engaged with the step portion 6 for positioning. After that, the hole 28 of the fixing plate 25 is positioned in the dowel 8 of the side surface portion 4, and while maintaining this state, the supporting plate 12 is fixed in the hollow portion 19 of the coil bobbin 15 from the supporting plate 12 side of the armature 10. The plate 25 is inserted until it comes into the notch 26. At this time, since the lower end portion of the cutout portion 26 of the fixed plate 25 projects upward from the lower end surface of the cutout portion 5 of the side surface portion 4, the front end portion of the armature 10 abuts the back surface of the fixed plate 25.
【００１４】 そして、保持板３０の打ち抜き孔３１に支持板１２の先端を嵌入させ、保持板 ３０を側面部４に沿って上方から下方に摺動させ、穴３５をダボ８に位置決めさ せて、ねじ３６を取付孔３４、２７を挿通させてねじ孔７に螺合させることによ り、保持板３０と固定板２５を側面部４に本固定する。このとき、凹部１４が凹 部３３に係合し、傾斜部１３が保持部３２により押し下げられるので、傾斜部１ ３のばね性により、図３に示すように、アーマチュア１０の先端の角部Ａがヨー ク２の側面部４の切欠部５の下端面に押し付けられ、同時に吸引部１１がヨーク ２の水平面部３ａから離間する方向に回動付勢される。換言すれば、アーマチュ ア１０は、点Ａを揺動支点として、ヨーク２に支持される。Then, the tip of the support plate 12 is fitted into the punching hole 31 of the holding plate 30, the holding plate 30 is slid from the upper side to the lower side along the side surface portion 4, and the hole 35 is positioned in the dowel 8. The holding plate 30 and the fixing plate 25 are finally fixed to the side surface portion 4 by inserting the screws 36 into the mounting holes 34 and 27 and screwing the screws 36 into the screw holes 7. At this time, since the concave portion 14 engages with the concave portion 33 and the inclined portion 13 is pushed down by the holding portion 32, due to the springiness of the inclined portion 13, as shown in FIG. Is pressed against the lower end surface of the cutout portion 5 of the side surface portion 4 of the yoke 2, and at the same time, the suction portion 11 is rotationally biased in a direction away from the horizontal surface portion 3 a of the yoke 2. In other words, the armature 10 is supported by the yoke 2 with the point A as the swing fulcrum.
【００１５】 このように組み立てられた電磁石のアーマチュア１０は、通常は、図２に示す ように、板ばね１２の傾斜部１３により、揺動支点Ａを中心として、吸引部１１ が水平面部３ａから離間する方向に回動付勢されており、コイル２３に通電され ると、揺動支点Ａを中心として、板ばね１２のばね性に抗して、吸引部１１が水 平面部３ａに吸引されて、アーマチュア１０が回動する。In the electromagnet armature 10 assembled in this way, as shown in FIG. 2, normally, the inclined portion 13 of the leaf spring 12 causes the suction portion 11 to move from the horizontal plane portion 3a about the swing fulcrum A. When the coil 23 is energized to rotate away from the coil 23 and the coil 23 is energized, the suction portion 11 is attracted to the horizontal surface portion 3a against the elasticity of the leaf spring 12 about the swing fulcrum A. Then, the armature 10 rotates.
【００１６】 このように、アーマチュア１０の角部Ａがヨーク２の側面部４の切欠部５の下 端面に押し付けられこの点Ａを揺動支点として、ヨーク２に支持されることによ り、アーマチュア１０とヨーク２とが常に接触状態を保持するので、ヨーク２と アーマチュア１０との間の磁気効率が良好となり、アーマチュア１０に対する吸 引力が増大し、動作時間も短縮される。As described above, the corner portion A of the armature 10 is pressed against the lower end surface of the cutout portion 5 of the side surface portion 4 of the yoke 2 and is supported by the yoke 2 with the point A as a swing fulcrum. Since the armature 10 and the yoke 2 are always kept in contact with each other, the magnetic efficiency between the yoke 2 and the armature 10 is improved, the attraction force for the armature 10 is increased, and the operation time is shortened.
【００１７】[0017]
以上説明したように本考案によれば、一方の側面部の表面に取付けた固定板に アーマチュアの前端部を突き当てるとともに、ヨークの一方の側面部の切欠きの 上端部をアーマチュアの揺動支点とし、この揺動支点において、常にアーマチュ アをヨークと接触状態としているので、アーマチュアとヨークとの間の磁気効率 が向上し、このため、コイルの消費電力が少なく済み、また、アーマチュアの動 作時間も短縮される。さらに、アーマチュアに対する吸引力が増大するので、ア ーマチュアを復帰させる付勢力を大とすることが可能なので、外部からの振動、 衝撃に対しての誤動作も防止される。 As described above, according to the present invention, the front end of the armature is abutted against the fixing plate attached to the surface of one side surface, and the upper end of the notch on one side surface of the yoke is set as the swinging fulcrum of the armature. Since the armature is always in contact with the yoke at this swing fulcrum, the magnetic efficiency between the armature and the yoke is improved, which reduces the power consumption of the coil and the operation of the armature. It also saves time. Further, since the suction force for the armature is increased, the biasing force for returning the armature can be increased, and malfunctions due to external vibrations and shocks are also prevented.
