- the movable iron piece 4 When the coil 24 is energized and the electromagnet block 2 is excited, the movable iron piece 4 is attracted to the attracted portion 63 by the magnetic pole portion 25 of the iron core 22 and resists the urging force of the movable contact piece 52 as shown in FIG. Rotate. As a result, the movable contact piece 52 is elastically deformed, and the movable contact 62 is closed to the fixed contact 57 of the fixed contact piece 51.
- the movable iron piece 4 loses the attractive force of the iron core 22 and rotates by the elastic force of the movable contact piece 52.
- the second projecting portion 67 formed on the card member 65 of the movable iron piece 4 collides with the elastic contact portion 46 of the hinge spring 44.
- the second protrusion 67 is made of synthetic resin, and the elastic contact portion 46 is elastically deformed. And the contact state of the 2nd protrusion part 67 and the elastic contact part 46 is obtained early after the movable iron piece 4 starts rotation. Therefore, the collision sound hardly occurs.
- the first protrusion 66 made of synthetic resin contacts the intermediate portion of the yoke 41 while the movable contact piece 4 is further rotated to elastically deform the elastic contact portion 46. For this reason, the rotational speed of the movable iron piece 4 is reduced, and the generation of the collision sound is sufficiently suppressed here. As described above, the movable iron piece 4 smoothly returns to the initial position without generating a collision sound, and the movable contact 62 is separated from the fixed contact 57 and located at the open position.
- each magnetic circuit constitutes a closed loop, and there is almost no magnetic flux leakage to the surroundings.
- the presence of the intermediate protrusion 80 can effectively apply a magnetic force to the contact open / close position, that is, the arc generated between the contacts.
- a force acts on the generated arc in a direction perpendicular to the contact opening direction, and this arc is greatly extended, so that the arc is extinguished rapidly.
- the movable contact piece 52 is configured to open and close between the two fixed contact pieces 51, the arc current at the time of opening the contact flows in the direction shown in FIG.
- the magnetic poles of the permanent magnet 76 are set so as to have different polarities on the opposing surface so that a magnetic flux direction that can be deformed is obtained. That is, the arc is more reliably extinguished by deforming the arc toward the intermediate wall side of the connecting member 77. Therefore, if the configuration of the contact opening / closing part 3 is different, the magnetic pole of the permanent magnet 76 may be set according to the difference.
- the operating voltage of the electromagnet block 2 can be adjusted as follows. That is, the operating voltage of the electromagnet block 2 can be suppressed by changing the inclination angle of the elastic contact portion 46 of the hinge spring 44. Specifically, when the inclination angle of the elastic contact portion 46 with respect to the yoke 41 is increased, the magnetic field generated from the magnetic pole portion 25 of the iron core 22 acts on the attracted portion 63 of the movable iron piece 4 as shown in the graph of FIG. The position of the operating point can be changed with respect to a change in force (suction force curve).
- FIG. 14 shows a configuration in which a connection member 77 is composed of a first connection portion 111 and a second connection portion 112, as in the case shown in FIG. 13.
- the second side walls 115a and 115b are different from each other in that the second side walls 115a and 115b are not bent half, but are bent at right angles from the intermediate walls 113a and 113b in the same manner as the first side walls 114a and 114b.
- the 1st connection part 111 and the 2nd connection part 112 are used in the state which made the intermediate
- a closed loop of the magnetic circuit can be formed at each of the two contact opening / closing positions, and magnetic flux leakage can be more effectively prevented.
- FIG. 16 shows a structure in which the intermediate projecting portion 137 is a flat plate integrally projecting from the central portion of the intermediate wall 133.
- the intermediate projecting portion 137 is formed by welding, bonding, or the like a plate material having the same shape as the opposing walls 134a, 134b to the central portion of the intermediate wall 133 with respect to a substantially U-shaped member including the intermediate wall 133 and the opposing walls 134a, 134b. Alternatively, it may be formed at the same time as the facing wall during press working.

Description
接離可能な一対の接点からなる接点組を、少なくとも2組、接離方向とは直交する並設方向に配置してなる接点開閉部と、
前記接点開閉部を駆動して接点を開閉させる電磁石ブロックと、
前記全ての接点組に対して並設方向の両側と、前記各接点組の間とにそれぞれ突出する突出部を、中間部を介して互いに連続させてなる、磁性材料からなる接続部材と、少なくとも両側に位置する突出部の対向位置にそれぞれ設けた永久磁石とからなるアーク消弧部材と、
を備えたものである。
前記ケースは、前記アーク消弧部材の突出部及び永久磁石を配置可能な凹部を備えるのが好ましい。
前記接点は、前記ベースから突出する接触片の一端部に固定され、
前記アーク消弧部材は、前記接続部材の中間部を、前記接触片の突出方向側の接点近傍に配置するのが好ましい。
固定接触片と、この固定接触片に対向して配置した可動接触片とを有する接点開閉部を備え、電磁石ブロックを励磁・消磁して可動接触片を駆動し、この可動接触片に設けた可動接点を固定接触片に設けた固定接点に開閉するようにした電磁継電器であって、
前記固定接触片は、前記固定接点を有する、少なくとも2つで構成され、
前記可動接触片は、前記可動接点を有する、少なくとも一対の接触片部を備え、
前記各接触片部の両側と、各接点開閉位置の間とにそれぞれ突出する突出部を、中間部を介して互いに連続させた接続部材と、少なくとも両側に位置する突出部の対向位置にそれぞれ設けた永久磁石とからなるアーク消弧部材を設けたものである。
図1から図5は、本実施形態に係る電磁継電器を示す。この電磁継電器は、大略、ベース1に、電磁石ブロック2、接点開閉部3、及び、可動鉄片4を設け、ケース5を被せたものである。
ベース1は、図6に示すように、合成樹脂材料を成形加工することにより平面視矩形状に形成され、長手方向の2箇所には、第1装着部6と第2装着部7が設けられている(以下、長辺に沿って長手方向に延びる方向をX軸、短辺に沿って短手方向に延びる方向をY軸、高さ方向に延びる方向をZ軸として説明する)。
電磁石ブロック2は、図7及び図8に示すように、鉄心22にスプール23を介してコイル24を巻回したものである。
ヨーク41は、磁性材料を略L字形となるように折り曲げたものである。ヨーク41の一端部には、前記鉄心22の一端部を挿通して加締固定するための開口部41aが形成されている。ヨーク41の他端部は幅広となって、その下端部両側には突出部42がそれぞれ形成されている。両突出部42の間には、後述する可動鉄片4が位置し、一方の角部が可動鉄片4を回動可能に支持する支点として機能している。ヨーク41の中間部外面には、上下2箇所に加締用の突起43が形成されている。
接点開閉部3は、図4及び図5に示すように、銅等の導電性材料を板状にプレス加工した、固定接触片51と可動接触片52とで構成されている。
可動鉄片4は、図7及び図8に示すように、板状の磁性材料をプレス加工により略L字形に形成したものである。可動鉄片4の一端側は、鉄心22の磁極部25に吸引される被吸引部63である。被吸引部63の先端部及び基部は幅狭となっており、スプール23の底面に形成したガイド突部35と、ヨーク41の下端部に形成した突出部42との干渉がそれぞれ回避されている。可動鉄片4の他端側には開口部64が形成されている。開口部64にはヒンジバネ44が挿通し、被吸引部63の角部に圧接している。可動鉄片4の他端部は幅狭となっており、又、開口部64の上方側にはカード部材65が一体化されている。
ケース5は、図2に示すように、合成樹脂材料を下面が開口する箱状としたものである。ケース5の上面角部には密閉用孔71が形成されている。密閉用孔71は、ベース1とケース5の嵌合部分のシール後に熱封止される。ケース5の上面縁部(ガス抜き孔71と反対側)には、両側及び中央部にスリット状の凹部72がそれぞれ形成されている。各及ぶ72の間には、上面よりも窪んだ凹所73が形成されており、その上面中央部には突起74がそれぞれ形成されている。
続いて、前記構成からなる電磁継電器の組立方法について説明する。
次に、前記構成からなる電磁継電器の動作について説明する。
すなわち、ヒンジバネ44の弾性当接部46の傾斜角度を変更することにより、電磁石ブロック2の動作電圧を抑えることが可能となる。詳しくは、ヨーク41に対する弾性当接部46の傾斜角度を大きくすると、図12のグラフに示すように、鉄心22の磁極部25から発生させた磁界により可動鉄片4の被吸引部63に作用する力の変化(吸引力曲線)に対して、動作点の位置を変更することができる。つまり、弾性当接部46の傾斜角度を大きくすることにより、接点が開放してから第1突出部66に弾性当接部46が当接するまでの力を小さくして、そのときに必要となる力を抑えることができる。この結果、吸引力曲線が、図示されるものよりも小さい位置で変化するように、電磁石ブロック2の動作電圧を抑制することが可能となる。
なお、本発明は、前記実施形態に記載された構成に限定されるものではなく、種々の変更が可能である。
この構成によれば、前記実施形態に比べて磁束漏れをより一層効果的に防止することができ、永久磁石76にそれほど磁力の大きなものを使用しなくても、接点間に十分に磁束を集中させることが可能となる。
この構成によれば、2組の接点開閉位置のそれぞれで磁気回路の閉ループを形成することができ、磁束漏れをより一層効果的に防止することが可能となる。
この構成によれば、中間突出部127は前記実施形態のように両側部だけではなく、図13と同様に、ほぼ全面に中間突出部127を配置することができるようになっている。これにより、図13と同様に、磁束漏れを効果的に防止することが可能となる。
