Description

本発明は、電力量計などに内蔵されて、電力の供給を制御するためのパワーラッチングリレーに関するものである。 The present invention relates to a power latching relay that is built in a watt hour meter or the like and controls the supply of power.

従来、電力の供給を制御するためのパワーラッチングリレーとして、例えば、特開２０１０−４４９７３号公報（特許文献１）などに開示されたものが提案されている。 Conventionally, as a power latching relay for controlling supply of electric power, for example, one disclosed in JP 2010-44973 A (Patent Document 1) has been proposed.

特開２０１０−４４９７３号公報（特許文献１）に開示されたパワーラッチングリレーは、ケースの側壁部に沿って延びるバスバー６０（端子部材）に固定された可動バネ６４（可動接点部材）を、シャフト８１を中心に制限された角度を回動するＬ字型のアクチュエータ８０（回動リンク）に取り付けたカード１００で動かして接点の開閉を制御している。アクチュエータ８０には、永久磁石９５を挟んだアマチュア９０が取り付けられており、電磁石部３０に順方向・逆方向に電流を流すことで、アクチュエータ８０が動作する。 A power latching relay disclosed in Japanese Patent Application Laid-Open No. 2010-44973 (Patent Document 1) has a movable spring 64 (movable contact member) fixed to a bus bar 60 (terminal member) extending along a side wall portion of a case as a shaft. Opening and closing of the contacts is controlled by moving the card 100 attached to an L-shaped actuator 80 (rotating link) that rotates at a limited angle around 81. An actuator 90 having a permanent magnet 95 sandwiched therebetween is attached to the actuator 80, and the actuator 80 operates by causing a current to flow through the electromagnet unit 30 in the forward direction and the reverse direction.

特開２０１０−４４９７３号公報JP 2010-44973 A

しかしながら、特開２０１０−４４９７３号公報（特許文献１）に開示されたパワーラッチングリレーは、アクチュエータ８０を電磁石部３０で直接的に動作させる構成を採用しているため、ケース内の電磁石部３０の設置位置に制限がある。すなわち、電磁石部３０を固定接点を備えたバスバー７０の近傍に配置すると、Ｌ字型のアクチュエータ８０の２つのアーム部に囲まれる空間（図７のＡの符号を付した領域）に部材を配置することができない。そこで従来のパワーラッチングリレーでは、ケースに左延長部１１を設けることにより、ケース内に無駄な空間が生じないようにしているが、ケースの形状が矩形ではなくなってしまう問題が生じる。そのため、従来のパワーラッチングリレーでは、無駄な空間が生じないようにしながら、パワーラッチングリレーを更に小型化するのには限界があった。 However, since the power latching relay disclosed in Japanese Patent Application Laid-Open No. 2010-44973 (Patent Document 1) employs a configuration in which the actuator 80 is directly operated by the electromagnet unit 30, the electromagnet unit 30 in the case There are restrictions on the installation position. That is, when the electromagnet portion 30 is disposed in the vicinity of the bus bar 70 having a fixed contact, the member is disposed in a space surrounded by the two arm portions of the L-shaped actuator 80 (a region denoted by reference numeral A in FIG. 7). Can not do it. Therefore, in the conventional power latching relay, the left extension portion 11 is provided in the case so that no useless space is generated in the case, but there is a problem that the shape of the case is not rectangular. Therefore, the conventional power latching relay has a limit in further reducing the size of the power latching relay while avoiding useless space.

本発明の目的は、ケース内に無駄な空間が生じることがなく、小型化が可能なパワーラッチングリレーを提供することにある。 An object of the present invention is to provide a power latching relay that can be reduced in size without generating useless space in the case.

本発明の他の目的は、上記目的に加えて、耐衝撃性に優れたパワーラッチングリレーを提供することにある。 Another object of the present invention is to provide a power latching relay excellent in impact resistance in addition to the above object.

本発明の他の目的は、小型化しながらも、耐電圧性能を確保したパワーラッチングリレーを提供することにある。 Another object of the present invention is to provide a power latching relay that ensures a withstand voltage performance while being miniaturized.

本発明のパワーラッチングリレーは、大きく捉えて、絶縁ケースと、第１及び第２の端子部材と、可動接点部材と、回動リンクと、電磁コイル装置と、回動部材と、駆動部分とを備えている。絶縁ケースは、第１の方向に延びる第１の辺、第１の辺と直交する第２の方向に延びる第２の辺、第１の辺と平行に第１の方向に延びる第３の辺及び第２の辺と平行に第２の方向に延びる第４の辺からなる矩形状の底壁部と、第１及び第２の方向と直交する第３の方向に第１乃至第４の辺から立ち上がる第１乃至第４の側壁部とを備えた周壁部とを有するケース本体と、ケース本体の開口部を覆う閉塞部材とからなり、第４の側壁部に第２の方向に間隔を開けて設けられた第１及び第２の端子導出孔を備えている。第１の端子部材は、一端に接点部材固定部を有し且つ他端に端子部を備え、接点部材固定部が第１の側壁部と第２の側壁部の交差部近傍に位置し且つ第１の側壁部に沿って延びて、第１の端子導出孔から端子部を突出させるようにケース本体内に配置されている。可動接点部材は、一端が第１の端子部材の接点部材固定部に固定され、第１の端子部材に沿って延びて、他端に可動接点が設けられている。第２の端子部材は、第１の端子部材から第２の方向に間隔をあけて並び、可動接点と接触可能に対向する位置に固定接点を備え且つ第２の端子導出孔から端子部を突出させるようにケース本体内に配置されている。回動リンクは、第１の端子部材から第２の方向に間隔をあけて配置され、接点部材固定部の近傍にあって第３の方向に延びる第１の仮想中心線を中心にして回動する軸部と、接点部材固定部よりも可動接点に近い位置で可動接点部材と接触する接触部と、第１の仮想中心線と直交し接触部と第１の仮想中心線とを通る第１の仮想直線との間の角度が９０度以下となる第２の仮想直線に沿い第１の仮想中心線から所定の距離離れた位置にある被嵌合部とを備えている。電磁コイル装置は、第２の端子部材と第３の側壁部との間に配置されている。回動部材は、電磁コイル装置の発生する磁界の作用によって、第３の方向に延びる第２の仮想中心線を中心にして所定の角度範囲内を回動するように支持されている。駆動部分は、回動部材に設けられ且つ電磁コイル装置と第２の側壁部との間に形成された空間内に延びて回動リンクの被嵌合部と緩く嵌合される嵌合部を備え、回動部材と一緒に第２の仮想中心線を中心として所定の角度範囲と同じ角度範囲内を回動する。 The power latching relay of the present invention can be roughly divided into an insulating case, first and second terminal members, a movable contact member, a rotating link, an electromagnetic coil device, a rotating member, and a driving portion. I have. The insulating case includes a first side extending in the first direction, a second side extending in the second direction orthogonal to the first side, and a third side extending in the first direction parallel to the first side. And a rectangular bottom wall portion consisting of a fourth side extending in the second direction parallel to the second side, and the first to fourth sides in a third direction orthogonal to the first and second directions A case main body having a peripheral wall portion provided with first to fourth side wall portions that rise from the side wall, and a closing member that covers the opening of the case main body, and is spaced from the fourth side wall portion in the second direction. Provided with first and second terminal lead-out holes. The first terminal member has a contact member fixing portion at one end and a terminal portion at the other end, the contact member fixing portion is located near the intersection of the first side wall portion and the second side wall portion and It extends along the side wall portion of 1 and is arranged in the case body so as to project the terminal portion from the first terminal lead-out hole. One end of the movable contact member is fixed to the contact member fixing portion of the first terminal member, extends along the first terminal member, and a movable contact is provided at the other end. The second terminal member is arranged at a distance from the first terminal member in the second direction, has a fixed contact at a position facing the movable contact so as to be able to come into contact, and protrudes the terminal portion from the second terminal lead-out hole. It is arranged in the case body so that The rotation link is arranged around the first virtual center line that is disposed at a distance from the first terminal member in the second direction and is adjacent to the contact member fixing portion and extends in the third direction. A contact portion that contacts the movable contact member at a position closer to the movable contact than the contact member fixing portion, and a first portion that is orthogonal to the first virtual center line and passes through the contact portion and the first virtual center line. And a fitted portion located at a predetermined distance away from the first virtual center line along a second virtual straight line having an angle with the virtual straight line of 90 degrees or less. The electromagnetic coil device is disposed between the second terminal member and the third side wall. The rotating member is supported so as to rotate within a predetermined angular range about the second virtual center line extending in the third direction by the action of the magnetic field generated by the electromagnetic coil device. The drive portion includes a fitting portion that is provided on the rotation member and extends into a space formed between the electromagnetic coil device and the second side wall portion and is loosely fitted to the fitting portion of the rotation link. And rotating within the same angular range as the predetermined angular range around the second virtual center line together with the rotating member.

駆動部分の嵌合部と回動リンクの被嵌合部との嵌合状態は、駆動部分が所定の角度範囲内を回動することにより、回動リンクが制限された角度範囲内を回動するように構成されている。回動リンクは、電磁コイル装置のコイルに順方向の励磁電流が流れて駆動部分が所定の角度範囲の一端に位置するときに第１の位置にあり、電磁コイル装置のコイルに逆方向の励磁電流が流れて駆動部分が所定の範囲の他端に位置するときに第２の位置にある。そして、可動接点部材は、回動リンクが第１の位置にあるときに、接触部により押圧されて、可動接点と固定接点との接触が解除され、回動リンクが第２の位置にあるときに、接触部による押圧が解除されて可動接点と固定接点とが接触するように構成されている。 The fitting state between the fitting portion of the drive portion and the fitted portion of the rotation link is rotated within the angle range where the rotation link is limited by the drive portion rotating within a predetermined angle range. Is configured to do. The rotating link is in the first position when a forward excitation current flows through the coil of the electromagnetic coil device and the drive portion is positioned at one end of a predetermined angle range, and the reverse excitation is applied to the coil of the electromagnetic coil device. When the current flows and the drive part is located at the other end of the predetermined range, it is in the second position. The movable contact member is pressed by the contact portion when the rotation link is in the first position, the contact between the movable contact and the fixed contact is released, and the rotation link is in the second position. In addition, the movable contact and the fixed contact come into contact with each other by releasing the pressing by the contact portion.

このように各構成部材を配置すれば、回動リンクが第１の側壁部に沿って延びる第１の仮想直線と、第２の側壁部に沿って延びる第２の仮想直線に沿う形状にすることができるため、各構成部材を矩形状の絶縁ケース内に収納した場合に、無駄な空間が生じることがない。また、回動する駆動部分を介して回動リンクを回動させるように構成しているため、電磁コイル装置の配置位置をある程度自由に設定することが可能になる。そのため、絶縁ケース内に各構成部材を高い実装密度で収納することができ、パワーラッチングリレーを小型化することが可能になる。 If each constituent member is arranged in this way, the rotation link has a shape along the first imaginary straight line extending along the first side wall and the second imaginary straight line extending along the second side wall. Therefore, when each component member is housed in a rectangular insulating case, useless space does not occur. In addition, since the rotation link is configured to rotate via the rotating drive portion, the arrangement position of the electromagnetic coil device can be freely set to some extent. Therefore, each component can be stored in the insulating case with a high mounting density, and the power latching relay can be downsized.

回動部材を回動させることができれば電磁コイル装置及び回動部材の構成は任意である。例えば、電磁コイル装置は、所定の間隔をあけて第２の方向に並んで対向する一対の磁極片と、該一対の磁極片に磁気的に接続された鉄心と、鉄心を磁化するコイルとを備えた構造とすることができる。回動部材は、一対の磁極片の自由端部と対向する両端部に永久磁石により磁化されて極性の異なる磁極が発現するように構成する。そして、回動部材の回動中心である第２の仮想中心線を、一対の磁極片の間の間隔の中心を通るように配置する。このように電磁コイル装置及び回動部材を構成すれば、電磁コイル装置のコイルに流す電流の向きを順方向・逆方向に流すことで、接点の開閉を確実に行うことができる。また、回動部材が永久磁石によって磁化されているため、回動部材が回動する角度範囲の一端と他端において回動部材を自己保持することが可能であるため、回動部材を第１の位置または第２の位置に動かした後は、コイルに電流を流すことなく回動部材の位置を保持することができる。その結果、第１の方向、第２の方向及び第３の方向のいずれの方向に対する衝撃にも強くすることができ、且つ、回動部材を回動させた後にコイルに電流を流し続ける必要がないため、消費電力を抑えることができる。 The configuration of the electromagnetic coil device and the rotation member is arbitrary as long as the rotation member can be rotated. For example, an electromagnetic coil device includes a pair of magnetic pole pieces facing each other in a second direction at a predetermined interval, an iron core magnetically connected to the pair of magnetic pole pieces, and a coil that magnetizes the iron core. It can be set as the structure provided. The rotating member is configured such that magnetic poles having different polarities are developed by being magnetized by permanent magnets at both ends of the pair of magnetic pole pieces facing the free ends. And the 2nd virtual center line which is the rotation center of a rotation member is arrange | positioned so that the center of the space | interval between a pair of magnetic pole pieces may be passed. If the electromagnetic coil device and the rotating member are configured in this way, the contact can be reliably opened and closed by flowing the direction of the current flowing through the coil of the electromagnetic coil device in the forward direction and the reverse direction. In addition, since the rotating member is magnetized by the permanent magnet, the rotating member can be self-held at one end and the other end of the angle range in which the rotating member rotates. After moving to the position 2 or the second position, the position of the rotating member can be held without passing an electric current through the coil. As a result, it is possible to withstand impacts in any of the first direction, the second direction, and the third direction, and it is necessary to continue to pass current through the coil after rotating the rotating member. Therefore, power consumption can be reduced.

駆動部分の嵌合部と、回動リンクの被嵌合部とによる嵌合部分の構成も任意である。例えば、回動リンクの被嵌合部は、駆動部分の嵌合部を駆動部分の回動方向の両側から挟む第１及び第２の被当接部を有するように構成し、駆動部分が一方の方向に回動して、嵌合部が第１の被当接部を押圧することで回動リンクが第１の位置から第２の位置に変位し、駆動部分が他方の方向に回動して、嵌合部が第２の被当接部を押圧することで回動リンクが第２の位置から第１の位置に変位するように嵌合部と第１及び第２の被当接部の構造を定めればよい。 The structure of the fitting part by the fitting part of a drive part and the to-be-fitted part of a rotation link is also arbitrary. For example, the fitted portion of the rotation link is configured to have first and second abutted portions that sandwich the fitting portion of the drive portion from both sides in the rotation direction of the drive portion, and the drive portion is one side. When the fitting portion presses the first contacted portion, the rotation link is displaced from the first position to the second position, and the drive portion rotates in the other direction. Then, the fitting portion and the first and second contacted portions are displaced so that the rotation link is displaced from the second position to the first position when the fitting portion presses the second contacted portion. What is necessary is just to define the structure of a part.

可動接点部材は、可動接点を固定接点に接離できるものであれば構成は任意である。可動接点と固定接点を確実に接離するために、可動接点部材を第１の端子部材の接点部材固定部に固定される支持部と、この支持部から第１の端子部材に沿って延びて、自由端に可動接点が設けられた板バネ部とから構成してもよい。板バネ部は回動リンクが第２の位置から第１の位置に変位する過程で可動接点を固定接点に押し付ける力を蓄え、回動リンクが第２の位置に変位する際に力を放出するように構成されている。このように構成すれば、板バネ部が有するバネ力によって、可動接点を固定接点に確実に押し付けることができる。 The configuration of the movable contact member is arbitrary as long as the movable contact can contact and separate from the fixed contact. In order to securely contact and separate the movable contact and the fixed contact, a support portion that fixes the movable contact member to the contact member fixing portion of the first terminal member, and extends from the support portion along the first terminal member The leaf spring portion may be configured with a movable contact provided at the free end. The leaf spring portion stores a force that presses the movable contact against the fixed contact in the process of the rotation link being displaced from the second position to the first position, and releases the force when the rotation link is displaced to the second position. It is configured as follows. If comprised in this way, a movable contact can be reliably pressed on a fixed contact with the spring force which a leaf | plate spring part has.

支持部に曲げによる応力が集中することを防ぐために、さらに、支持部と隣接する位置に第１の仮想直線に向かって凸になった屈曲部または湾曲部を設けてもよい。その場合には、回動リンクの軸部と接触部との間に、回動リンクと板バネ部の屈曲部または湾曲部が干渉しないようにするための凹部を形成しておけばよい。また、板を撓ませる荷重は、板の厚みの３乗に比例して増加することが知られている。ただし、板バネ部には電流が流れるため、電気的な抵抗を下げる必要もある。そのため、板バネ部を撓ませやすくし、且つ、電気抵抗を低くするために、可動接点部材を２枚以上の金属板を重ねて構成して、屈曲部または湾曲部において、金属板の相互間に隙間が生じるように板バネ部の形状を定めることが好ましい。 In order to prevent stress due to bending from concentrating on the support part, a bent part or a curved part that protrudes toward the first virtual straight line may be provided at a position adjacent to the support part. In that case, it is only necessary to form a recess for preventing the rotating link and the bent portion or the bending portion of the leaf spring portion from interfering between the shaft portion and the contact portion of the rotating link. Further, it is known that the load for bending the plate increases in proportion to the cube of the plate thickness. However, since an electric current flows through the leaf spring portion, it is necessary to lower the electrical resistance. Therefore, in order to make the leaf spring part easier to bend and lower the electric resistance, the movable contact member is formed by stacking two or more metal plates, and the bent portions or the curved portions are arranged between the metal plates. It is preferable to define the shape of the leaf spring portion so that a gap is formed in the plate.

絶縁ケース内にコンパクトに各構成部材を収納すると、各構成部材間の距離も近づくため、耐電圧性能が低くなる。そこで、各構成部材間、特に、接近した状態で配置されている可動接点部材と電磁コイル装置との間に、電磁コイル装置と可動接点部材とを電気的に絶縁する絶縁隔壁を設けることが好ましい。絶縁隔壁を設けることで、沿面距離が伸びて、耐電圧性能を確保することができる。 When each component member is housed in a compact manner in the insulating case, the withstand voltage performance is lowered because the distance between the component members is also reduced. Therefore, it is preferable to provide an insulating partition that electrically insulates the electromagnetic coil device and the movable contact member between the constituent members, in particular, between the movable contact member and the electromagnetic coil device that are arranged close to each other. . By providing the insulating partition wall, the creepage distance can be extended and the withstand voltage performance can be ensured.

絶縁隔壁は、沿面距離を長くして絶縁効果を高めるために、ケース本体の底壁部から第３の方向に延びて、第１乃至第４の側壁部よりも低い第１の絶縁隔壁と、閉塞部材からケース本体に向かって第３の方向に延びて、第１の絶縁壁と組み合わせられる第２の絶縁壁部とから構成することができる。 In order to increase the creepage distance and enhance the insulation effect, the insulating partition wall extends from the bottom wall portion of the case body in the third direction and is lower than the first to fourth side wall portions; A second insulating wall portion that extends in the third direction from the closing member toward the case body and is combined with the first insulating wall can be used.

可動接点を固定接点に対して確実に押し付けるようにするために、コイル部と、互いに対して９０度以下の角度でコイル部の接線方向に突出する一対のアーム部とを一体に備えたトーションスプリングをさらに備えるようにすることができる。トーションスプリングのコイル部を回動リンクの軸部に固定し、トーションスプリングの一対のアーム部の一方を、第２の仮想直線に沿って回動リンクに固定し、トーションスプリングの一対のアーム部の他方を、可動接点部材の板バネ部に固定することで、可動接点を固定接点に向かって付勢することができる。 A torsion spring integrally including a coil portion and a pair of arm portions projecting in a tangential direction of the coil portion at an angle of 90 degrees or less with respect to each other in order to press the movable contact with respect to the fixed contact. Can be further provided. The coil portion of the torsion spring is fixed to the shaft portion of the rotation link, and one of the pair of arm portions of the torsion spring is fixed to the rotation link along the second imaginary straight line. By fixing the other to the leaf spring portion of the movable contact member, the movable contact can be biased toward the fixed contact.

なお、トーションスプリングを備えながら、パワーラッチングリレーの第３の方向の寸法を大きくしないようにするために、可動接点部材に、トーションスプリングの一対のアーム部の他方を通すためのスリットを形成し、可動接点部材の他端には、トーションスプリングの一対のアーム部の他方の端部が接触する接触部を設けてもよい。このように構成すれば、トーションスプリングを可動接点部材に形成されたスリットに通すことができ、パワーラッチングリレーの第３の方向の寸法を小さくできる。また、可動接点部材の中央にスリットを形成することで、可動接点を均等に付勢することが可能になる。 In addition, a slit for passing the other of the pair of arm portions of the torsion spring is formed in the movable contact member so as not to increase the dimension in the third direction of the power latching relay while including the torsion spring. You may provide the contact part which the other edge part of a pair of arm part of a torsion spring contacts in the other end of a movable contact member. If comprised in this way, a torsion spring can be passed through the slit formed in the movable contact member, and the dimension of the 3rd direction of a power latching relay can be made small. In addition, by forming a slit in the center of the movable contact member, the movable contact can be evenly biased.

なお、コイルには、第１の端子部材と第２の端子部材との間に流す制御対象の交流電圧を半波整流して得られる交流電圧と同期した動作電圧を印加し、一方の極性の動作電圧を印加すると順方向の励磁電流が流れ、他方の極性の動作電圧を印加することで逆方向の励磁電流が流れる励磁回路を用いて励磁電流を供給することができる。このような励磁回路を用いる場合には、交流電圧がゼロになるタイミングで回動部材が回動するように、コイルの巻数、永久磁石の保持力並びに回動部材の重量及び形状を決定することにより、可動接点と固定接点とが接触する際、また、接触が解除される際のアークの発生による接点の消耗を軽減することができる。 The coil is applied with an operating voltage synchronized with the AC voltage obtained by half-wave rectifying the AC voltage to be controlled flowing between the first terminal member and the second terminal member, and having one polarity. When an operating voltage is applied, an exciting current in the forward direction flows, and by applying an operating voltage of the other polarity, the exciting current can be supplied using an exciting circuit in which an exciting current in the reverse direction flows. When using such an excitation circuit, determine the number of turns of the coil, the holding force of the permanent magnet, and the weight and shape of the rotating member so that the rotating member rotates at the timing when the AC voltage becomes zero. Accordingly, it is possible to reduce contact consumption due to generation of an arc when the movable contact and the fixed contact come into contact with each other and when the contact is released.

［パワーラッチングリレーの動作］
図４（Ａ）及び（Ｂ）並びに図５（Ａ）及び（Ｂ）により、本実施の形態のパワーラッチングリレー１の開閉動作を説明する。図４（Ａ）及び図５（Ａ）は、閉塞部材７を取り除いた状態を示すパワーラッチングリレー１の平面図である。図４（Ｂ）及び図５（Ｂ）は、接点の開閉を説明するために、端子部材９，１３、可動接点部材１１、トーションスプリング９５以外の部材を省略し、また、回動リンク１５の形状を点線で表した図である。 [Operation of power latching relay]
The opening / closing operation of the power latching relay 1 of this embodiment will be described with reference to FIGS. 4 (A) and 4 (B) and FIGS. 5 (A) and 5 (B). 4 (A) and 5 (A) are plan views of the power latching relay 1 showing a state where the blocking member 7 is removed. 4B and 5B, members other than the terminal members 9 and 13, the movable contact member 11, and the torsion spring 95 are omitted in order to explain the opening and closing of the contacts. It is the figure which represented the shape with the dotted line.

＜開動作＞
図４（Ａ）及び（Ｂ）は、本実施の形態のパワーラッチングリレー１が開状態になった状態を示している。すなわち、後述の閉状態のパワーラッチングリレー１のコイル１０１に接続された給電用端子１２３Ａ，１２３Ｂから電流を流して、磁極片１０９の自由端部１１３にＮ極が発現し、磁極片１１１の自由端部１１５にＳ極が発現するようにコイル１０１を励磁すると、磁性金属片１３１の端部１３１ａが磁極片１０９に吸引され、また、磁性金属片１２９の端部１２９ｂが磁極片１１１に吸引されて回動部材１９が第２の仮想中心線ＩＣ２を中心にして回動する。すると、回動部材１９と一緒に回動する駆動部分２１によって第１の被当接部８９Ａが押圧され、回動リンク１５が第１の仮想中心線ＩＣ１を中心に回動して第１の位置（開状態）に位置するようになる。回動リンク１５が第１の位置にあると、回動リンク１５の接触部８５により押圧されて、可動接点６５，６５と固定接点７５，７５との接触が解除されて接点が開状態になり、電力が供給されない状態になる。 <Opening action>
4A and 4B show a state in which the power latching relay 1 of the present embodiment is in an open state. That is, current flows from power supply terminals 123A and 123B connected to the coil 101 of the power latching relay 1 in the closed state, which will be described later, and an N pole appears at the free end 113 of the pole piece 109, thereby freeing the pole piece 111. When the coil 101 is excited so that the S pole appears at the end 115, the end 131 a of the magnetic metal piece 131 is attracted to the magnetic pole piece 109, and the end 129 b of the magnetic metal piece 129 is attracted to the magnetic pole piece 111. Thus, the rotation member 19 rotates about the second virtual center line IC2. Then, the first abutted portion 89A is pressed by the drive portion 21 that rotates together with the rotation member 19, and the rotation link 15 rotates about the first virtual center line IC1 to form the first It comes to be in the position (open state). When the rotation link 15 is in the first position, it is pressed by the contact portion 85 of the rotation link 15 to release the contact between the movable contacts 65, 65 and the fixed contacts 75, 75, and the contact is opened. The power is not supplied.

＜閉動作＞
図５（Ａ）及び（Ｂ）は、本実施の形態のパワーラッチングリレー１が閉状態になった状態を示している。すなわち、開状態のパワーラッチングリレー１のコイル１０１に接続された給電用端子１２３Ａ，１２３Ｂから開動作の場合と逆方向の電流を流して、磁極片１０９の自由端部１１３にＳ極が発現し、磁極片１１１の自由端部１１５にＮ極が発現するようにコイル１０１を励磁すると、磁性金属片１２９の端部１２９ａが磁極片１０９に吸引され、また、磁性金属片１３１の端部１３１ｂが磁極片１１１に吸引されて回動部材１９が第２の仮想中心線ＩＣ２を中心にして回動する。すると、回動部材１９と一緒に回動する駆動部分２１によって第２の被当接部８９Ｂが押圧され、回動リンク１５が第１の仮想中心線ＩＣ１を中心に回動して第２の位置（閉状態）に位置するようになる。回動リンク１５が第２の位置にあると、回動リンク１５の接触部８５の押圧が解除されて、可動接点６５，６５と固定接点７５，７５とが接触し、接点が閉状態になり、電力が供給される状態になる。 <Closed action>
5A and 5B show a state where the power latching relay 1 of the present embodiment is in a closed state. That is, a current in the direction opposite to that in the opening operation is supplied from the power feeding terminals 123A and 123B connected to the coil 101 of the power latching relay 1 in the open state, and the S pole appears at the free end 113 of the pole piece 109. When the coil 101 is excited so that the N pole appears at the free end 115 of the magnetic pole piece 111, the end 129a of the magnetic metal piece 129 is attracted to the magnetic pole piece 109, and the end 131b of the magnetic metal piece 131 is The rotating member 19 is attracted by the magnetic pole piece 111 and rotates about the second virtual center line IC2. Then, the second contacted portion 89B is pressed by the drive portion 21 that rotates together with the rotation member 19, and the rotation link 15 rotates about the first virtual center line IC1 to form the second It comes to be in the position (closed state). When the rotation link 15 is in the second position, the pressing of the contact portion 85 of the rotation link 15 is released, the movable contacts 65 and 65 and the fixed contacts 75 and 75 come into contact, and the contact is closed. , Power is supplied.

なお、図５（Ｂ）に示すように、可動接点部材１１の接触部６９は、トーションスプリング９５のアーム部９９Ｂによって押圧されるように構成されているため可動接点６５，６５と固定接点７５，７５とが確実に接触する。 5B, the contact portion 69 of the movable contact member 11 is configured to be pressed by the arm portion 99B of the torsion spring 95, so that the movable contacts 65, 65 and the fixed contact 75, 75 is in reliable contact.

本実施の形態では、回動部材１９が回動して接点が開状態または閉状態になった後は、逆方向に励磁電流を流すまでは、永久磁石１２７の有する磁力によって回動部材１９の位置は自己保持される。したがって、パワーラッチングリレー１が動作したことを確認できた後は、励磁電流を止めることが可能であり、開状態・閉状態を変更したいときにのみコイル１０１の励磁電流を流せばよく、また、励磁電流の向きを変えることにより、接点の開状態・閉状態を切り替えることが可能である。 In the present embodiment, after the rotating member 19 is rotated and the contact is in the open state or the closed state, the magnetic force of the permanent magnet 127 is applied until the exciting current is applied in the reverse direction. The position is self-holding. Therefore, after confirming that the power latching relay 1 has been operated, it is possible to stop the exciting current, and it is only necessary to flow the exciting current of the coil 101 only when it is desired to change the open state / closed state. By changing the direction of the exciting current, it is possible to switch the contact between the open state and the closed state.

［コイルの励磁］
接点を開閉させるためには、接点を開閉する必要がある時にコイル１０１に直流電流を流せばよい。しかしながら、固定接点７５，７５と可動接点６５，６５との消耗を軽減するために、本実施の形態では、コイル１０１に励磁電流を流すタイミングを最適化できる励磁回路を有効に利用して動作するようにパワーラッチングリレーが設計されている。 [Excitation of coil]
In order to open and close the contacts, a direct current may be passed through the coil 101 when the contacts need to be opened and closed. However, in order to reduce the consumption of the fixed contacts 75 and 75 and the movable contacts 65 and 65, the present embodiment operates by effectively using an excitation circuit that can optimize the timing of supplying an excitation current to the coil 101. The power latching relay is designed as follows.

図６（Ａ）は、パワーラッチングリレー１で制御する対象の主回路の交流電圧波形である。すなわち、第１の端子部材９と第２の端子部材１３の間に印加される交流の電圧波形である。本実施の形態のパワーラッチングリレー１に対して適用することが望まれる励磁回路は、図６（Ａ）の交流電圧波形を入力として、半波整流を行い、交流電圧波形と同期した図６（Ｂ）に示す動作電圧を出力する。この励磁回路では、図６（Ｂ）に示すように、接点を開状態から閉状態にする場合は、正の極性の半波をコイルに印加し、接点を閉状態から開状態にする場合には、負の極性の半波をコイルに印加して、図６（Ｃ）に示す波形の励磁電流を流す。本実施の形態のパワーラッチングリレーでは、接点の開閉指示が出てから交流電圧がゼロになるタイミング（図６の例では、ｔ１及びｔ２）で回動部材１９が回動するように、コイル１０１の巻数、永久磁石１２７の保持力並びに回動部材１９を構成する磁性金属片１２９，１３１の重量及び形状（特に、端部１２９ａ，１２９ｂ、１３１ａ，１３１ｂの重量及び形状）を定めている（図６（Ｄ））。そのため、固定接点７５，７５と可動接点６５，６５とが接触する際、また、接触が解除される際には、接点間にほとんど電流が流れず、アークの発生による接点の消耗を防ぐことができる。接点が開閉されることにより、第１の端子部材９と第２の端子部材１３には、図６（Ｅ）の波形の電圧が出力されることになる。 FIG. 6A is an AC voltage waveform of the main circuit to be controlled by the power latching relay 1. That is, an AC voltage waveform applied between the first terminal member 9 and the second terminal member 13. The excitation circuit that is desired to be applied to the power latching relay 1 of the present embodiment receives the AC voltage waveform of FIG. 6A as an input, performs half-wave rectification, and is synchronized with the AC voltage waveform of FIG. The operating voltage shown in B) is output. In this excitation circuit, as shown in FIG. 6B, when the contact is changed from the open state to the closed state, a positive half wave is applied to the coil, and the contact is changed from the closed state to the open state. Applies a negative half-wave to the coil and passes an excitation current having a waveform shown in FIG. In the power latching relay of the present embodiment, the coil 101 is rotated so that the rotating member 19 rotates at a timing (t1 and t2 in the example of FIG. 6) when the AC voltage becomes zero after the contact opening / closing instruction is issued. , The holding force of the permanent magnet 127, and the weight and shape of the magnetic metal pieces 129, 131 constituting the rotating member 19 (particularly, the weight and shape of the end portions 129a, 129b, 131a, 131b) are determined (FIG. 6 (D)). Therefore, when the fixed contacts 75 and 75 and the movable contacts 65 and 65 come into contact with each other and when the contact is released, almost no current flows between the contacts, thereby preventing contact consumption due to the occurrence of an arc. it can. When the contact is opened and closed, the voltage having the waveform of FIG. 6E is output to the first terminal member 9 and the second terminal member 13.

なお、本実施の形態では、回動リンク１５の形状はＬ字型であるが、回動リンク１５の形状はこれに限られるものではなく、第１の仮想直線ＩＬ１と第２の仮想直線ＩＬ２との間の角度θが９０度以下となる条件を満たせば、どのような形状のものを採用してもよい。 In the present embodiment, the shape of the rotation link 15 is L-shaped, but the shape of the rotation link 15 is not limited to this, and the first virtual straight line IL1 and the second virtual straight line IL2 are not limited thereto. Any shape may be adopted as long as the condition that the angle θ between and the angle θ is 90 degrees or less is satisfied.

また、駆動部分の嵌合部１３９と回動リンクの被嵌合部８９による嵌合は、本実施の嵌合構造に限られるものではない。例えば、回動リンクの端部に駆動部分の回動軌道に合わせた形状の溝を形成して、この溝に沿って駆動部分の嵌合部が動くような嵌合構造を採用してもよい。 In addition, the fitting by the fitting portion 139 of the driving portion and the fitted portion 89 of the rotation link is not limited to the fitting structure of the present embodiment. For example, a fitting structure may be employed in which a groove having a shape matching the rotation trajectory of the drive portion is formed at the end of the rotation link, and the fitting portion of the drive portion moves along this groove. .

本発明によれば、回動リンクが第１の側壁部に沿って延びる第１の仮想直線と、第２の側壁部に沿って延びる第２の仮想直線に沿う形状にすることができ、また、電磁コイル装置の配置位置を自由に設定することが可能になり、ケース内に無駄な空間が生じることがなく、小型化が可能なパワーラッチングリレーを得ることができる。また、可動接点と固定接点を確実に固定することができるため、耐衝撃性に優れたパワーラッチングリレーを得ることができる。さらに、小型化しながらも、耐電圧性能を確保したパワーラッチングリレーを得ることができる。 According to the present invention, the rotation link can be shaped along a first imaginary straight line extending along the first side wall and a second imaginary straight line extending along the second side wall. The arrangement position of the electromagnetic coil device can be freely set, and a power latching relay that can be reduced in size without generating a useless space in the case can be obtained. In addition, since the movable contact and the fixed contact can be securely fixed, a power latching relay excellent in impact resistance can be obtained. Furthermore, it is possible to obtain a power latching relay that ensures a withstand voltage performance while being miniaturized.
