Description
そこで、本発明は、上記従来例の未解決の課題に着目してなされたものであり、復帰用付勢力を増大することなく、耐振動衝撃性能を向上させることができる電磁開閉器を提供することを目的としている。
また、本発明に係る電磁開閉器の第2の態様は、前記永久磁石が、前記消弧室容器の対向側壁の外側における前記可動接触子の長手方向と直交する位置に当該可動接触子と対向して配設されている。
また、本発明に係る電磁開閉器の第3の態様は、前記磁気回路が、前記永久磁石と対向する消弧室容器の内面側における前記一対の固定接触子間に対向して配設されて前記開成位置の可動プランジャと接触する第1の磁気ヨークと、前記可動プランジャの前記第1の磁気ヨークと接触する部位とは反対側の部位に対向するとともに、前記永久磁石の背面側に接する第2の磁気ヨークとを備えている。
図1は本発明の接点装置を電磁開閉器としての電磁接触器に適用した場合の一例を示す断面図である。この図1において、1は接点装置であって、この接点装置1の下面側に電磁石装置2が配設されている。
接点装置1は、例えば非磁性体且つ絶縁体又は内壁に絶縁処理を施した密閉容器である消弧室容器3を有し、この消弧室容器3内に接点機構4が配設されている。消弧室容器3は、下端面が開放された有底筒体3aと、この有底筒体3aの下端面を閉塞する底板部3bとで構成されている。底板部3bは、中央部に後述する可動プランジャ13の軸部13aを挿通する挿通孔3cが形成されている。
また、可動接触子5は、図1及び図2に示すように、平板状に形成され、固定接触子4a,4bの上端側に所定距離を隔てて接離自在に対向配置されている。この可動接触子5は後述する可動プランジャ13に固定支持された接触子ホルダ6に接触スプリング7によって下方に付勢されて装着されている。
