Description

本発明は、電磁リレーに係り、特に絶縁性部材にて形成されたベースに、電磁石部、接極子、カード、可動端子及び固定端子が並列に設けられた電磁リレーに関する。   The present invention relates to an electromagnetic relay, and more particularly to an electromagnetic relay in which an electromagnet portion, an armature, a card, a movable terminal, and a fixed terminal are provided in parallel on a base formed of an insulating member.

上述した電磁リレーとして、例えば特許文献1に記載されたものが知られている。図8は、従来の電磁リレーに示す側面図である。同図に示すように、電磁リレー10は、樹脂等の絶縁性部材にて方形状に形成されたベース20に、電磁石部21、接極子22、カード23、可動端子24及び固定端子25が並列に設けられたものである。電磁石部21は、ヨーク21aと、ヨーク21aに固定したコイル21bとから構成される。電磁石部21に通電することで電磁力を発生し、接極子22を吸着する。   As the electromagnetic relay described above, for example, the one described in Patent Document 1 is known. FIG. 8 is a side view showing a conventional electromagnetic relay. As shown in the figure, in an electromagnetic relay 10, an electromagnet portion 21, an armature 22, a card 23, a movable terminal 24, and a fixed terminal 25 are arranged in parallel on a base 20 formed in a rectangular shape with an insulating member such as resin. Is provided. The electromagnet portion 21 includes a yoke 21a and a coil 21b fixed to the yoke 21a. By energizing the electromagnet portion 21, electromagnetic force is generated and the armature 22 is attracted.

接極子22は、略く字状に形成されており、中央部22aが電磁石部21の上端のヨーク21a側で支承されている。また、接極子22は、図示せぬヒンジバネによって電磁石部21に固定されている。図8は、電磁石部21に通電を行っていないときの状態を示している。この状態では、接極子22は、先端部22bがカード23に接触した状態で停止しているが、電磁石部21に通電が行われると、基端部22cが電磁石部21に吸着されるので中央部22aを中心に回動する。電磁石部21への通電が行われなくなると、接極子22はヒンジバネによって元の状態に戻る。すなわち、接極子22の先端部22bがカード23に接触した状態に戻る。   The armature 22 is formed in a substantially square shape, and the central portion 22 a is supported on the yoke 21 a side at the upper end of the electromagnet portion 21. The armature 22 is fixed to the electromagnet portion 21 by a hinge spring (not shown). FIG. 8 shows a state when the electromagnet portion 21 is not energized. In this state, the armature 22 is stopped with the distal end portion 22b in contact with the card 23. However, when the electromagnet portion 21 is energized, the proximal end portion 22c is attracted to the electromagnet portion 21 so It rotates around the part 22a. When the electromagnet portion 21 is not energized, the armature 22 returns to the original state by the hinge spring. That is, it returns to the state where the tip 22b of the armature 22 is in contact with the card 23.

カード23は、支軸23bと、第1の枝部23dと、第2の枝部23fとから構成される。支軸23bは、ベース20に回動自在に支承された下端部23aから伸張する部分である、第1の枝部23dは、支軸23b上の一点から接極子22に接触する第1の圧接点23cに向けて支軸23bに対して垂直な方向に伸張する部分である。第2の枝部23fは、支軸23b上の他の一点から可動端子24に接触する第2の圧接点23eに向けて支軸23bに対して垂直な方向に伸張する部分である。カード23は、ベース20の軸受け部20aで接極子22及び可動端子24の方向へ回動自在に支承されており、接極子22の回動に連動して回動し、可動端子24の可動接点24aを固定端子25の固定接点25aに接触させる。   The card 23 includes a support shaft 23b, a first branch portion 23d, and a second branch portion 23f. The support shaft 23b is a portion that extends from a lower end portion 23a that is rotatably supported by the base 20, and the first branch portion 23d is a first pressure contact that contacts the armature 22 from one point on the support shaft 23b. This is a portion that extends in a direction perpendicular to the support shaft 23b toward the point 23c. The second branch portion 23f is a portion that extends in a direction perpendicular to the support shaft 23b from the other point on the support shaft 23b toward the second pressure contact 23e that contacts the movable terminal 24. The card 23 is supported by the bearing portion 20 a of the base 20 so as to be rotatable in the direction of the armature 22 and the movable terminal 24, and is rotated in conjunction with the rotation of the armature 22. 24 a is brought into contact with the fixed contact 25 a of the fixed terminal 25.

上述した従来の電磁リレー10は、カード23の可動端子24を押す第2の圧接点23eが、接極子22と接触する第1の圧接点23cよりも上方にあり、カード23が下端を中心に回動して可動端子24の可動接点24aと固定端子25の固定接点25aをオン・オフするようにしている。しかしながら、このような構造では次のような課題が生ずる。すなわち、接極子22とカード23が回動したときに、図8中の矢印Aで示すように、上方に力が逃げてカード23が可動端子24を水平に押すことができないため、可動端子24の可動接点24aと固定端子25の固定接点25aとが全面で均一に接触しない。   In the conventional electromagnetic relay 10 described above, the second pressure contact 23e that pushes the movable terminal 24 of the card 23 is above the first pressure contact 23c that contacts the armature 22, and the card 23 is centered on the lower end. By rotating, the movable contact 24a of the movable terminal 24 and the fixed contact 25a of the fixed terminal 25 are turned on / off. However, such a structure causes the following problems. That is, when the armature 22 and the card 23 are rotated, as indicated by an arrow A in FIG. 8, the force escapes upward and the card 23 cannot push the movable terminal 24 horizontally. The movable contact 24a and the fixed contact 25a of the fixed terminal 25 do not contact uniformly over the entire surface.

本発明は前記実情に鑑みてなされたものであり、接極子がカードを略水平に押すことができて、可動端子の可動接点と固定端子の固定接点とを略全面で接触させることができる電磁リレーを提供することを目的とする。   The present invention has been made in view of the above situation, and an armature can push a card substantially horizontally, so that a movable contact of a movable terminal and a fixed contact of a fixed terminal can be brought into contact with substantially the entire surface. The purpose is to provide a relay.

本発明の電磁リレーは、絶縁性部材で形成されたベースに立設され、可動接点を有する可動端子と、固定接点を有し、該固定接点が前記可動端子の可動接点と対向させて前記ベースに立設された固定端子と、前記可動端子から離間し、前記ベースに立設された電磁石部と、前記電磁石部の先端に支点を有し、前記電磁石部に通電することで回動する接極子と、前記可動端子と前記接極子との間に位置し、前記ベースにて前記接極子及び前記可動端子の方向に回動自在に支承され、前記接極子と接触する第1の圧接点を有するとともに、前記第1の圧接点から離間した位置で前記可動端子と接触する第2の圧接点を有するカードと、を具備する電磁リレーであって、前記カードと前記接極子の当接面のうち少なくとも一方が、他方から離間する方向に傾斜した傾斜面を有する。   The electromagnetic relay of the present invention is erected on a base formed of an insulating member, has a movable terminal having a movable contact, and a fixed contact, and the fixed contact is opposed to the movable contact of the movable terminal. A fixed terminal that is erected on the base, an electromagnet portion that is erected on the base and spaced from the movable terminal, and a fulcrum at the tip of the electromagnet portion that rotates by energizing the electromagnet portion. A first pressure contact that is positioned between a pole, the movable terminal, and the armature, is rotatably supported by the base in the direction of the armature and the movable terminal, and contacts the armature. And a card having a second pressure contact that contacts the movable terminal at a position spaced apart from the first pressure contact, the electromagnetic relay comprising a contact surface between the card and the armature At least one of them is separated from the other It has an inclined surface that is inclined direction.

また、上記電磁リレーにおいて、前記傾斜面は、面とり部で構成される。   Moreover, the said electromagnetic relay WHEREIN: The said inclined surface is comprised by the chamfering part.

また、上記電磁リレーにおいて、前記接極子の前記傾斜面は、前記接極子を前記第1の圧接点近傍で曲げ加工することで形成される。   In the electromagnetic relay, the inclined surface of the armature is formed by bending the armature in the vicinity of the first pressure contact.

また、上記電磁リレーにおいて、前記カードは、支軸と、前記支軸上の一点から前記第1の圧接点に向けて前記支軸に対して垂直な方向に伸張する第1の枝部と、前記支軸上の他の一点から前記第2の圧接点に向けて前記支軸に対して垂直な方向に伸張する第2の枝部とを具備する。   In the electromagnetic relay, the card includes a support shaft, a first branch portion extending in a direction perpendicular to the support shaft from one point on the support shaft toward the first pressure contact, A second branch extending in a direction perpendicular to the support shaft from the other point on the support shaft toward the second pressure contact.

また、上記電磁リレーにおいて、前記カードは、前記支軸の少なくとも一部を含みそれぞれ前記支点から前記第1の圧接点及び前記第2の圧接点を結ぶ第1及び第2の梁部を備える。   In the electromagnetic relay, the card includes first and second beam portions that include at least a part of the support shaft and connect the first pressure contact and the second pressure contact from the fulcrum, respectively.

本発明は、ベースに対してカードを接極子及び可動端子の方向に回動自在でかつ水平方向に僅かに前後可能に支承するとともに、接極子とカードとの当接面のうち少なくとも一方に、他方から離間する方向に傾斜させた傾斜面を設けたので、接極子がカードを略水平に押すことができ、可動端子の可動接点と固定端子の固定接点を略全面で接触させることができる。   The present invention supports the card so that it can rotate in the direction of the armature and the movable terminal with respect to the base and can be slightly moved back and forth in the horizontal direction, and at least one of the contact surfaces of the armature and the card, Since the inclined surface inclined in the direction away from the other side is provided, the armature can push the card substantially horizontally, and the movable contact of the movable terminal and the fixed contact of the fixed terminal can be brought into contact with substantially the entire surface.

以下、本発明を実施するための好適な実施の形態について、図面を参照して詳細に説明する。   DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments for carrying out the invention will be described in detail with reference to the drawings.

図1は、本発明の一実施の形態に係る電磁リレーを示す側面図である。なお、図1において前述した図8と共通する部分には同一の符号を付けている。   FIG. 1 is a side view showing an electromagnetic relay according to an embodiment of the present invention. 1 that are the same as those in FIG. 8 described above are denoted by the same reference numerals.

図1において、本実施の形態の電磁リレー1は、電磁石部21と、接極子22と、ベース2と、カード3と、可動端子24と、固定端子25とを備える。カード3とベース2以外の電磁石部21、接極子22、可動端子24及び固定端子25の各部材は、前述した図8の従来の電磁リレー10の各部材と同一のものであるので、説明を省略する。   In FIG. 1, the electromagnetic relay 1 of the present embodiment includes an electromagnet unit 21, an armature 22, a base 2, a card 3, a movable terminal 24, and a fixed terminal 25. Since the members of the electromagnet portion 21, the armature 22, the movable terminal 24, and the fixed terminal 25 other than the card 3 and the base 2 are the same as those of the conventional electromagnetic relay 10 shown in FIG. Omitted.

ベース2は、従来の電磁リレー10のベース20と同様に樹脂等の絶縁性部材にて方形状に形成されている。このベース2に、電磁石部21、カード3、可動端子24及び固定端子25が並列に立設される。特に、ベース2のカード3を支承するカード支承部2aは、カード3の下端部(支点)3aを回動自在でかつ水平方向に前後移動可能とする両端円弧状の長方形空間として形成されている。カード3の詳細は後述するが、図2に示すように、カード3の下端部3aが2分割され、それぞれ水平方向に靴底状に突出したキック部をなすように形成されている。図2(a)は左側面図、図2(b)は右側面図である。この下端部3aがベース2のカード支承部2aに収容される。望ましくはカード支承部2aも、小突起2bを有し、カード下端部3aの中心を支承するようにしてもよい。   The base 2 is formed in a square shape with an insulating member such as a resin, like the base 20 of the conventional electromagnetic relay 10. On the base 2, an electromagnet portion 21, a card 3, a movable terminal 24, and a fixed terminal 25 are erected in parallel. In particular, the card support portion 2a for supporting the card 3 of the base 2 is formed as a rectangular space having a circular arc shape on both ends that allows the lower end portion (fulcrum) 3a of the card 3 to be rotatable and move back and forth in the horizontal direction. . Although details of the card 3 will be described later, as shown in FIG. 2, the lower end portion 3a of the card 3 is divided into two parts, and each is formed so as to form a kick part protruding in the shape of a shoe sole in the horizontal direction. 2A is a left side view, and FIG. 2B is a right side view. This lower end portion 3 a is accommodated in the card support portion 2 a of the base 2. Desirably, the card support part 2a may also have a small protrusion 2b to support the center of the card lower end part 3a.

図3は、ベース2のカード支承部2aを上から見た図である。カード3の下端部3aは、カード支承部2aで回動自在でかつ水平方向(矢印B、Cで示す方向)に前後移動可能に支承される。カード支承部2aの水平方向の長さL1が、可動端子24の可動接点24aと固定端子25の固定接点25a間の距離を超える大きさとなっており、カード3の水平方向の移動距離を可動接点24aと固定接点25a間の距離以上となるようにしている。   FIG. 3 is a view of the card support portion 2a of the base 2 as viewed from above. The lower end 3a of the card 3 is supported by the card support 2a so as to be rotatable and movable back and forth in the horizontal direction (directions indicated by arrows B and C). The horizontal length L1 of the card support portion 2a is larger than the distance between the movable contact 24a of the movable terminal 24 and the fixed contact 25a of the fixed terminal 25, and the horizontal movement distance of the card 3 is determined by the movable contact. It is made to be more than the distance between 24a and the fixed contact 25a.

カード3は、ベース2上の接極子22と可動端子24との間に位置し、ベース2にて接極子22及び可動端子24の方向へ回動自在に支承される。図4は、カード3の概観を示す図である。同図において、カード3は、前述した下端部3aから伸張する支軸3bの他に、第1の枝部3dと、第2の枝部3fと、梁部3g及び梁部3hとを備える。第1の枝部3dは、支軸3b上の一点から第1の圧接点3cに向けて支軸3bに対して垂直方向に伸張されたものである。第2の枝部3fは、支軸3b上の他の一点から第2の圧接点3eに向けて支軸3bに対して垂直方向に伸張されたものである。梁部3gは、支軸3bを含み下端部3aから第1の圧接点3cを結ぶ三角形状を成すものである。梁部3hは、支軸3bを含み下端部3aから第2の圧接点3eを結ぶ三角形状を成すものである。本実施の形態の電磁リレー1のカード3は、図8に示す従来の電磁リレー10のカード23と比べて梁部3g、3hを有している分、機械的強度が大きく、撓み難くなっている。ちなみに、この梁部3g、3hがない従来の場合すなわち、図9(a)に示すように形成した場合、動作時に、図9(b)に示すように撓みが生じ、接点位置がずれ、良好なオン・オフ動作ができなくなることがある。   The card 3 is positioned between the armature 22 on the base 2 and the movable terminal 24, and is supported by the base 2 so as to be rotatable in the direction of the armature 22 and the movable terminal 24. FIG. 4 is a diagram showing an overview of the card 3. In the figure, the card 3 includes a first branch portion 3d, a second branch portion 3f, a beam portion 3g and a beam portion 3h in addition to the support shaft 3b extending from the lower end portion 3a. The first branch portion 3d extends in a direction perpendicular to the support shaft 3b from one point on the support shaft 3b toward the first pressure contact 3c. The second branch portion 3f extends in the direction perpendicular to the support shaft 3b from the other point on the support shaft 3b toward the second pressure contact 3e. The beam portion 3g has a triangular shape including the support shaft 3b and connecting the first pressure contact 3c from the lower end portion 3a. The beam portion 3h has a triangular shape including the support shaft 3b and connecting the second pressure contact 3e from the lower end portion 3a. Compared with the card 23 of the conventional electromagnetic relay 10 shown in FIG. 8, the card 3 of the electromagnetic relay 1 according to the present embodiment has the beam portions 3g and 3h, and therefore has high mechanical strength and is difficult to bend. Yes. By the way, in the conventional case without these beam portions 3g and 3h, that is, when formed as shown in FIG. 9A, bending occurs as shown in FIG. On / off operation may not be possible.

カード3の第1の枝部3dの先端が面取りされている。図5は、接極子22とカード3との接触箇所を示す図である。同図に示すように、カード3の第1の枝部3dの接極子22と接触する当接面3iには、接極子22から離間する方向に面取りされている。カード3の第1の枝部3dの先端を面取りしたことと、カード3をベース2に対して回動自在でかつ水平方向に前後移動を可能にしたことにより、接極子22が略水平にカード3を押すことができる。またこのとき、梁部3g、3hで補強されたカード3が容易に撓むことがないので、接極子22はカード3を確実に押すことができる。カード2を略水平に押すことで、可動端子24の可動接点24aと固定端子25の固定接点25aを略全面で接触させることができる。   The tip of the first branch 3d of the card 3 is chamfered. FIG. 5 is a diagram illustrating a contact portion between the armature 22 and the card 3. As shown in the figure, the contact surface 3 i that contacts the armature 22 of the first branch 3 d of the card 3 is chamfered in a direction away from the armature 22. Since the tip of the first branch portion 3d of the card 3 is chamfered and the card 3 is rotatable with respect to the base 2 and can be moved back and forth in the horizontal direction, the armature 22 can be moved substantially horizontally. 3 can be pressed. At this time, since the card 3 reinforced by the beam portions 3g and 3h is not easily bent, the armature 22 can reliably push the card 3. By pushing the card 2 substantially horizontally, the movable contact 24a of the movable terminal 24 and the fixed contact 25a of the fixed terminal 25 can be brought into contact with substantially the entire surface.

このように、本実施の形態の電磁リレー1によれば、カード3をベース2に対して回動自在でかつ水平方向に前後移動可能に支承するとともに、カード3の第1の枝部3dの先端の接極子22と接触する当接面3iに対し、接極子22から離間する方向に面取りしたので、接極子22が略水平にカード3を押すことができ、可動端子24の可動接点24aと固定端子25の固定接点25aを略全面で接触させることができる。   Thus, according to the electromagnetic relay 1 of the present embodiment, the card 3 is supported so as to be rotatable with respect to the base 2 and movable back and forth in the horizontal direction, and the first branch 3d of the card 3 is supported. Since the contact surface 3i that contacts the front armature 22 is chamfered in a direction away from the armature 22, the armature 22 can push the card 3 substantially horizontally, and the movable contact 24a of the movable terminal 24 The fixed contact 25a of the fixed terminal 25 can be brought into contact with substantially the entire surface.

なお、本実施の形態の電磁リレー1では、カード3側に面取りを行ったが、接極子22側に面取りを行うようにしてもよいし、カード3と接極子22の双方で行ってもよい。   In the electromagnetic relay 1 of the present embodiment, the chamfering is performed on the card 3 side, but the chamfering may be performed on the armature 22 side, or both the card 3 and the armature 22 may be performed. .

図6は、接極子22側に面取りを行った場合の接極子22とカード3との接触箇所を示す図である。同図に示すように、接極子22のカード3の第1の枝部3dと接触する当接面22dには、カード3の第1の枝部3dから離間する方向に面取りされている。接極子22側に面取りを行っても接極子22が略水平にカード3を押すことができる。   FIG. 6 is a diagram illustrating a contact portion between the armature 22 and the card 3 when chamfering is performed on the armature 22 side. As shown in the figure, the contact surface 22d of the armature 22 that contacts the first branch 3d of the card 3 is chamfered in a direction away from the first branch 3d of the card 3. Even if the armature 22 is chamfered, the armature 22 can push the card 3 substantially horizontally.

また、面取りを行う以外に、例えば接極子22の先端部22bを曲げ加工して傾斜面を形成することも可能である。図7は、接極子22の先端部22bを曲げ加工して傾斜面を形成した場合の接極子22とカード3との接触箇所を示す図である。同図に示す例では、接極子22の先端部22bをカード3の第1の圧接点3c近傍で曲げ加工して傾斜面22eを形成したものである。一般的に接極子22には金属が用いられることから、曲げ加工を容易に行うことができる。接極子22の先端部22bを曲げ加工して傾斜面22eを形成しても接極子22が略水平にカード3を押すことができ、可動端子24の可動接点24aと固定端子25の固定接点25aを略全面で接触させることができる。傾斜面22eは面とり部22fで構成される。
なお、第1及び第2の梁部は、支軸を含む面であってもよいし、支軸の少なくとも一部を含み、それぞれ第1及び第2の圧接点に向けて伸張する線状部材であってもよい。
In addition to chamfering, for example, the tip 22b of the armature 22 can be bent to form an inclined surface. FIG. 7 is a diagram illustrating a contact portion between the armature 22 and the card 3 when the tip 22b of the armature 22 is bent to form an inclined surface. In the example shown in the figure, the tip 22b of the armature 22 is bent near the first pressure contact 3c of the card 3 to form an inclined surface 22e. Since metal is generally used for the armature 22, bending can be easily performed. Even if the tip 22b of the armature 22 is bent to form the inclined surface 22e, the armature 22 can push the card 3 substantially horizontally, and the movable contact 24a of the movable terminal 24 and the fixed contact 25a of the fixed terminal 25 can be pressed. Can be brought into contact with substantially the entire surface. The inclined surface 22e includes a chamfered portion 22f.
The first and second beam portions may be surfaces including a support shaft, or include at least a part of the support shaft, and linear members that extend toward the first and second pressure contacts, respectively. It may be.
