Description

本発明は、電磁継電器に関する。   The present invention relates to an electromagnetic relay.

特許文献1に開示されている電磁継電器は、内部に収容部を有する矩形箱形の樹脂製ハウジングと、このハウジングに固定された2つの固定接点側端子および2つの可動接点側端子とを備えている。この電磁継電器の収容部には、各固定接点側端子に設けられた2つの固定接点部と、各可動接点側端子に設けられた2つの可動接触片と、各可動接触片に設けられかつ各固定接点部に対向するように配置された2つの可動接点部と、供給された電流の方向により極性が反転する電磁石部と、電磁石部の極性に応じて異なる方向に回動する1つの回動ブロックと、回動ブロックと各可動接触片とを接続する2つの可動部材とを備えている。   The electromagnetic relay disclosed in Patent Document 1 includes a rectangular box-shaped resin housing having an accommodating portion therein, and two fixed contact side terminals and two movable contact side terminals fixed to the housing. Yes. The accommodating portion of the electromagnetic relay includes two fixed contact portions provided on each fixed contact side terminal, two movable contact pieces provided on each movable contact side terminal, and each movable contact piece provided on each movable contact piece. Two movable contact portions arranged so as to face the fixed contact portion, an electromagnet portion whose polarity is reversed depending on the direction of the supplied current, and one rotation that rotates in different directions depending on the polarity of the electromagnet portion A block, and two movable members that connect the rotating block and each movable contact piece are provided.

前記電磁継電器では、回動ブロックが回動することで、各可動部材を移動させて各可動接触片を弾性変形させて、可動接点部を対向する固定接点部に対して接触または開離させるようになっている。また、回動ブロックは、内部に永久磁石が収容された直方体状のハウジングと、このハウジングを挟むように配置された2つの矩形板状の鉄片とで構成されている。2つの鉄片の一方には、鉄片の長手方向の先端部から鉄片の長手方向に延びる腕部を有している。   In the electromagnetic relay, as the rotating block rotates, each movable member is moved, each movable contact piece is elastically deformed, and the movable contact portion is brought into contact with or separated from the opposite fixed contact portion. It has become. The rotating block includes a rectangular parallelepiped housing in which a permanent magnet is accommodated, and two rectangular plate-shaped iron pieces arranged so as to sandwich the housing. One of the two iron pieces has an arm portion extending in the longitudinal direction of the iron piece from the longitudinal end portion of the iron piece.

US2009/0033446A1US2009 / 0033446A1

前記電磁継電器では、各可動部材に、鉄片の腕部を係止する係止孔が設けられており、鉄片の腕部を可動部材の係止孔で係止することで、回動ブロックと各可動部材とが接続されているため、各可動部材は、回動ブロックの鉄片の腕部の延在方向に対して十分に位置規制されていない。このため、回動ブロックの回動に伴う各可動部材の動作が安定せず、例えば、可動接触片を十分に弾性変形させることができなかったり、また、移動中に各可動部材が他の部材と接触して発生した樹脂屑により各可動接点部と対応する固定接点部との間に接触不良が生じたりして、各可動接点部と対応する固定接点部との間の接触信頼性が低下するおそれがある。   In the electromagnetic relay, each movable member is provided with a locking hole for locking the arm portion of the iron piece, and by locking the arm portion of the iron piece with the locking hole of the movable member, Since the movable member is connected, the position of each movable member is not sufficiently regulated with respect to the extending direction of the arm portion of the iron piece of the rotating block. For this reason, the operation of each movable member accompanying rotation of the rotation block is not stable, for example, the movable contact piece cannot be sufficiently elastically deformed, or each movable member is moved to another member during movement. The contact reliability between each movable contact part and the corresponding fixed contact part is lowered due to the resin waste generated in contact with each other, resulting in poor contact between each movable contact part and the corresponding fixed contact part. There is a risk.

そこで、本発明は、固定接点部および可動接点部間の接触信頼性を向上できる電磁継電器を提供することを課題とする。   Then, this invention makes it a subject to provide the electromagnetic relay which can improve the contact reliability between a fixed contact part and a movable contact part.

位置規制部93は、板状を有し、一対の壁部91における第1腕部721の延在方向の先端部側の端部(すなわち、図6の上端部)に設けられ、第1腕部721の溝部77に配置されて、第1可動部材90の第1腕部721の延在方向(図6の上下方向)への位置を規制する。位置規制部93は、回動軸71の延在方向において、接続部92の連結部921から一対の突起部922に向かって延びており、その先端部931が、連結部921と一対の突起部922との間に位置している。   The position restricting portion 93 has a plate shape and is provided at an end portion on the distal end side in the extending direction of the first arm portion 721 (that is, the upper end portion in FIG. 6) in the pair of wall portions 91, and the first arm It arrange | positions at the groove part 77 of the part 721, and regulates the position to the extending direction (up-down direction of FIG. 6) of the 1st arm part 721 of the 1st movable member 90. FIG. The position restricting portion 93 extends from the connecting portion 921 of the connecting portion 92 toward the pair of projecting portions 922 in the extending direction of the rotation shaft 71, and the distal end portion 931 thereof is connected to the connecting portion 921 and the pair of projecting portions. 922.

なお、第1可動部材90の一対の壁部91、接続部92、および、位置規制部93は一体に形成されており、一対の壁部91における位置規制部93の先端部931から一対の突起部922までの部分911が、相互に離れる方向に弾性変形可能になっている。これにより、第1可動部材90を第1腕部721に対して着脱可能に接続できるようになっている。   The pair of wall portions 91, the connecting portion 92, and the position restricting portion 93 of the first movable member 90 are integrally formed, and a pair of protrusions from the distal end portion 931 of the position restricting portion 93 in the pair of wall portions 91. Portions 911 up to the portion 922 can be elastically deformed in directions away from each other. Thereby, the 1st movable member 90 can be connected with respect to the 1st arm part 721 so that attachment or detachment is possible.

第2可動部材100は、図2に示すように、ベース11の第2側壁112に沿って延びる略直方体状を有し、その長手方向の第3側壁113側の端部(すなわち、図2の上端部)で回動ブロック70の第2腕部722に接続され、その長手方向の第4側壁114側(すなわち、図2の下端部)で第2可動接触片51に接続されている。この第2可動部材100は、回動ブロック70の回動方向に応じて移動して第2可動接触片51を弾性変形させて第2可動接点部52を第2固定接点部41に対して接触または開離させる。   As shown in FIG. 2, the second movable member 100 has a substantially rectangular parallelepiped shape extending along the second side wall 112 of the base 11, and an end portion on the third side wall 113 side in the longitudinal direction (that is, in FIG. 2). The upper end portion is connected to the second arm portion 722 of the rotation block 70, and is connected to the second movable contact piece 51 on the fourth side wall 114 side in the longitudinal direction (that is, the lower end portion in FIG. 2). The second movable member 100 moves in accordance with the rotation direction of the rotation block 70 to elastically deform the second movable contact piece 51 to contact the second movable contact portion 52 with the second fixed contact portion 41. Or let it open.

詳しくは、第2可動部材100は、回動ブロック70の回動を第2可動接点部52が第2固定接点部41に対して接触または開離する接離方向(すなわち、図2の上下方向)の直線運動に変換可能であり、かつ、回動ブロック70の第2腕部722の先端部に回動ブロック70の回動を許容しつつ接続されていると共に、第2可動接触片51の延在方向における第2側壁112側の端部(すなわち、図2の右側の端部)に接続されている。すなわち、第2可動部材100は、回動ブロック70の回動により接離方向に移動して、第2可動接触片51の延在方向における第2側壁112側の端部を第2可動接点部52が第2固定接点部41に対して接触または開離する接離方向に移動させる。   Specifically, the second movable member 100 is configured so that the rotation of the rotation block 70 is in the contact / separation direction in which the second movable contact portion 52 contacts or separates from the second fixed contact portion 41 (ie, the vertical direction in FIG. 2). ) And is connected to the distal end portion of the second arm portion 722 of the rotation block 70 while allowing the rotation of the rotation block 70, and the second movable contact piece 51. It is connected to the end on the second side wall 112 side in the extending direction (that is, the end on the right side in FIG. 2). That is, the second movable member 100 moves in the contact / separation direction by the rotation of the rotation block 70, and the end portion on the second side wall 112 side in the extending direction of the second movable contact piece 51 is moved to the second movable contact portion. 52 moves in the contact / separation direction in which the second fixed contact portion 41 contacts or separates.

なお、第2可動部材100は、第1可動部材90と同じ構成を有している。このため、第2可動部材100についての説明は、第1可動部材90の説明を援用して、省略する。   The second movable member 100 has the same configuration as the first movable member 90. For this reason, the description of the second movable member 100 is omitted by using the description of the first movable member 90.

前記電磁継電器1では、図2に示す動作状態(すなわち、回動ブロック70の第2鉄片75の第1端部751が、第1ヨーク62の吸着部622に接触し、回動ブロック70の第1鉄片74の第2端部742が、第2ヨーク63の吸着部632に接触して、第1可動接点部32と第1固定接点部21とが接触し、第2可動接点部52と第2固定接点部41とが接触した状態)の電磁継電器1の電磁石部60に所定方向(例えば、図2のA方向)の電流を供給して、回動ブロック70を回動ブロック70の回動軸71の延在方向から見て時計回りに回転させる。すると、回動ブロック70の回転に伴って、各腕部721、722も時計回りに回転し、第1可動部材90をベース11の第4側壁114に向かって移動させて、第1可動接点部32を第1固定接点部21から開離させると共に、第2可動部材100をベース11の第3側壁113に向かって移動させて、第2可動接点部52を第2固定接点部41から開離させる。これにより、電磁継電器1は、動作状態から復帰状態(すなわち、回動ブロック70の第1鉄片74の第1端部741が、第1ヨーク62の吸着部622に接触し、回動ブロック70の第2鉄片75の第2端部752が、第2ヨーク63の吸着部632に接触して、第1可動接点部32が第1固定接点部21から開離し、第2可動接点部52が第2固定接点部41から開離接触した状態)になる。   In the electromagnetic relay 1, the operation state shown in FIG. 2 (that is, the first end 751 of the second iron piece 75 of the rotating block 70 comes into contact with the suction portion 622 of the first yoke 62, and the The second end portion 742 of the iron piece 74 comes into contact with the suction portion 632 of the second yoke 63, the first movable contact portion 32 and the first fixed contact portion 21 come into contact, and the second movable contact portion 52 and the second 2 in a state in which the fixed contact portion 41 is in contact) current in a predetermined direction (for example, direction A in FIG. 2) is supplied to the electromagnet portion 60 of the electromagnetic relay 1 to rotate the rotation block 70. The shaft 71 is rotated clockwise as viewed from the extending direction. Then, along with the rotation of the rotation block 70, the arm portions 721 and 722 also rotate clockwise to move the first movable member 90 toward the fourth side wall 114 of the base 11, and thereby the first movable contact portion. 32 is separated from the first fixed contact portion 21, and the second movable member 100 is moved toward the third side wall 113 of the base 11 to separate the second movable contact portion 52 from the second fixed contact portion 41. Let As a result, the electromagnetic relay 1 returns from the operating state (that is, the first end 741 of the first iron piece 74 of the rotation block 70 contacts the suction portion 622 of the first yoke 62). The second end 752 of the second iron piece 75 comes into contact with the suction portion 632 of the second yoke 63, the first movable contact portion 32 is separated from the first fixed contact portion 21, and the second movable contact portion 52 is the second movable contact portion 52. 2 is in a state of being in contact with the fixed contact portion 41.

動作状態の電磁継電器1では、第1可動接触片31に対して、接離方向に交差する第1可動接触片31の延在方向の一方側(例えば、図2の左側)に配置されている第1固定接点側端子20または第1可動接点側端子30(ここでは、第1固定接点側端子20)が、電流が供給される端子である。また、第2可動接触片51に対して、第1可動接触片31の延在方向の他方側(例えば、図2の右側)に配置されている第2固定接点側端子40または第2可動接点側端子50(ここでは、第2固定接点側端子40)が、電流が供給される端子である。すなわち、前記電磁継電器1では、通電時において、第1固定接点側端子20、第1可動接点側端子30、および、第1可動接触片31で構成される導通経路と、第2固定接点側端子40、第2可動接点側端子50、および、第2可動接触片51で構成される導通経路とに、相互に反対方向の電流が流れる。   In the electromagnetic relay 1 in the operating state, the first movable contact piece 31 is disposed on one side (for example, the left side in FIG. 2) in the extending direction of the first movable contact piece 31 that intersects the contact / separation direction. The first fixed contact side terminal 20 or the first movable contact side terminal 30 (here, the first fixed contact side terminal 20) is a terminal to which current is supplied. Further, the second fixed contact side terminal 40 or the second movable contact disposed on the other side (for example, the right side in FIG. 2) of the first movable contact piece 31 in the extending direction with respect to the second movable contact piece 51. The side terminal 50 (here, the second fixed contact side terminal 40) is a terminal to which current is supplied. That is, in the electromagnetic relay 1, when energized, the conduction path constituted by the first fixed contact side terminal 20, the first movable contact side terminal 30, and the first movable contact piece 31, and the second fixed contact side terminal. 40, currents in opposite directions flow through the conduction path formed by the second movable contact side terminal 50 and the second movable contact piece 51.

また、復帰状態の電磁継電器1の電磁石部60に所定方向とは異なる方向(例えば、図2のB方向)の電流を供給して、回動ブロック70を回動ブロック70の回動軸71の延在方向から見て反時計回りに回転させる。すると、回動ブロック70の回転に伴って、各腕部721、722も反時計回りに回転し、第1可動部材90をベース11の第3側壁113に向かって移動させて、第1可動接点部32を第1固定接点部21に対して接触させると共に、第2可動部材100をベース11の第4側壁114に向かって移動させて、第2可動接点部52を第2固定接点部41に対して接触させる。   Further, a current in a direction different from a predetermined direction (for example, a B direction in FIG. 2) is supplied to the electromagnet portion 60 of the electromagnetic relay 1 in the restored state, so that the rotation block 70 is connected to the rotation shaft 71 of the rotation block 70. Rotate counterclockwise when viewed from the extending direction. Then, as the rotation block 70 rotates, the arm portions 721 and 722 also rotate counterclockwise, and the first movable member 90 is moved toward the third side wall 113 of the base 11, so that the first movable contact is made. The portion 32 is brought into contact with the first fixed contact portion 21, and the second movable member 100 is moved toward the fourth side wall 114 of the base 11, so that the second movable contact portion 52 becomes the second fixed contact portion 41. Make contact.

前記電磁継電器1では、第1可動部材90が、位置規制部93により回動ブロック70の第1腕部721の延在方向に対して位置規制され、第2可動部材100が、位置規制部93により回動ブロック70の第2腕部722の延在方向に対して位置規制されているため、回動ブロック70の回動に伴う第1可動部材90および第2可動部材100の動作の安定性を高めることができる。その結果、例えば、各可動接触片31、51を十分に弾性変形させることができなかったり、また、移動中に各可動部材90、100が他の部材と接触して発生した樹脂屑により各可動接点部32、52と対応する固定接点部21、41との間に接触不良が生じたりすることを防止して、第1固定接点部21および第1可動接点部32間の接触信頼性、および、第2固定接点部41および第2可動接点部52間の接触信頼性を向上できる。   In the electromagnetic relay 1, the position of the first movable member 90 is restricted by the position restricting portion 93 with respect to the extending direction of the first arm portion 721 of the rotation block 70, and the second movable member 100 is restricted by the position restricting portion 93. Therefore, the position of the second arm portion 722 of the rotating block 70 is restricted with respect to the extending direction of the rotating block 70, so that the operation of the first movable member 90 and the second movable member 100 accompanying the rotation of the rotating block 70 is stable. Can be increased. As a result, for example, the movable contact pieces 31 and 51 cannot be sufficiently elastically deformed, or the movable members 90 and 100 are moved by the resin scrap generated when the movable members 90 and 100 come into contact with other members during the movement. The contact reliability between the first fixed contact portion 21 and the first movable contact portion 32 is prevented by preventing contact failure between the contact portions 32 and 52 and the corresponding fixed contact portions 21 and 41, and The contact reliability between the second fixed contact portion 41 and the second movable contact portion 52 can be improved.

また、一対の壁部91が、相互に離れる方向に弾性変形可能であり、第1腕部721および第2腕部722の先端部の溝部77よりも回動軸71の近くでかつ回動軸71の延在方向の他方の端部に、一対の突起部922を着脱可能に係止する凹部78が設けられている。これにより、第1可動部材90を第1腕部721に対して着脱可能に接続でき、第2可動部材100を第2腕部722に対して着脱可能に接続できるので、電磁継電器1の組み立てが容易になり、生産性の高い電磁継電器1を実現できる。   Further, the pair of wall portions 91 can be elastically deformed in a direction away from each other, closer to the rotation shaft 71 than the groove portion 77 at the distal end portion of the first arm portion 721 and the second arm portion 722 and the rotation shaft. A recess 78 is provided at the other end in the extending direction of 71 to detachably engage the pair of protrusions 922. Accordingly, the first movable member 90 can be detachably connected to the first arm portion 721, and the second movable member 100 can be detachably connected to the second arm portion 722. Therefore, the assembly of the electromagnetic relay 1 can be performed. It becomes easy and the electromagnetic relay 1 with high productivity can be realized.

また、第1腕部721および第2腕部722が、先端部の接離方向の両側にそれぞれ設けられ、一対の壁部91に向かって突出する一対の湾曲面79を有し、一対の湾曲面79の各々が、対向する一対の壁部91の各々に接触して第1腕部721および第2腕部722を揺動可能に配置されている。これにより、回動ブロック70の回動を接離方向の直線運動に円滑に変換することができる。   Further, the first arm portion 721 and the second arm portion 722 have a pair of curved surfaces 79 provided on both sides in the contact / separation direction of the tip portion and projecting toward the pair of wall portions 91, respectively, and a pair of curves Each of the surfaces 79 is disposed so as to be able to swing the first arm portion 721 and the second arm portion 722 in contact with each of the pair of opposing wall portions 91. Thereby, rotation of the rotation block 70 can be smoothly converted into linear movement in the approaching / separating direction.

なお、前記電磁継電器1では、第1固定接点側端子20、第1可動接点側端子30、および、第1可動接触片31で構成された回路と、第2固定接点側端子40、第2可動接点側端子50、および、第2可動接触片51で構成された回路とが設けられているが、これに限らない。回路数は、少なくとも1つあればよい。すなわち、固定接点側端子、可動接点側端子、および、第1可動接触片の組を少なくとも1組備えていればよい。   In the electromagnetic relay 1, a circuit composed of the first fixed contact side terminal 20, the first movable contact side terminal 30, and the first movable contact piece 31, the second fixed contact side terminal 40, and the second movable contact side. Although the circuit comprised by the contact side terminal 50 and the 2nd movable contact piece 51 is provided, it is not restricted to this. The number of circuits may be at least one. That is, it is only necessary to include at least one set of the fixed contact side terminal, the movable contact side terminal, and the first movable contact piece.

また、各腕部721、722の凹部78は、省略することができる。すなわち、各腕部721、722は、対応する可動部材90、100に対して着脱可能でなくても構わない。   Further, the concave portions 78 of the arm portions 721 and 722 can be omitted. That is, the arm portions 721 and 722 may not be detachable from the corresponding movable members 90 and 100.

また、各腕部721、722に湾曲面79を設けているが、これに限らない。回動ブロック70の回動を接離方向の直線運動に変換することができれば、湾曲面79は省略してもよいし、他の構成を採用してもよい。   Moreover, although the curved surface 79 is provided in each arm part 721,722, it is not restricted to this. As long as the rotation of the rotation block 70 can be converted into a linear motion in the approaching / separating direction, the curved surface 79 may be omitted or another configuration may be adopted.
