Description
固定/可動接点間に接点溶着が生じた状態でのトリップ動作時に、ラッチが上リンクの拘束干渉を受けずに釈放位置へ回動可能となるよう、トグルリンクの上リンクとラッチとの間をスライド可能に枢支連結するものとし、具体的には上リンクの上端に長穴形の軸受部を形成し、該軸受部の長穴にラッチに設けた連結軸部を嵌合してラッチと上リンクとの間をスライド可能に枢支連結する。
また、接点が溶着した状態でのトリップ動作で可動接触子が開極しない場合に、手動によるハンドル操作でハンドルがOFF位置に移動するのを阻止するアイソレーション機構として、上リンクの側縁に凸状カムを形成するとともに、該凸状カムに対向してハンドルレバーのON側サイドにアーム状のストッパ片を設ける(請求項2)。

Claims (2)
- 主回路の固定接触子および回動式の接触子ホルダに保持した可動接触子、接触子ホルダに連繋した開閉機構、操作ハンドル、および過電流引外し装置を装備した回路遮断器であって、前記開閉機構が、先端をフレームに枢支して操作ハンドルに結合したハンドルレバーと、一端をフレームに軸支し、常時は先端爪部をラッチ受けに係止して鎖錠位置に係止保持されているラッチと、トグルピンを介して結合された上リンクと下リンクからなり、上リンク,下リンクの他端をそれぞれラッチ,接触子ホルダに枢支連結して架け渡したトグルリンクと、前記トグルピンとハンドルレバーの上端との間に張架した開閉スプリングとの組立体からなり、ハンドルのON,OFF操作により主回路接点を開閉し、また過電流の通流時には前記ラッチを釈放して開閉機構をトリップ動作させるようにしたものにおいて、
固定/可動接点間に接点溶着が生じた状態でのトリップ動作時に、ラッチが上リンクの拘束干渉を受けずに釈放位置へ回動可能となるよう、上リンクの上端に長穴形の軸受部を形成し、該軸受部の長穴にラッチに設けた連結軸部を嵌合してトグルリンクの上リンクとラッチとの間をスライド可能に枢支連結したことを特徴とする回路遮断器。 - 請求項1に記載の回路遮断器において、主回路接点が溶着した状態で操作ハンドルがOFF位置に移動するのを阻止するアイソレーション機構として、上リンクの側縁に凸状カムを形成するとともに、該凸状カムに対向してハンドルレバーのON側サイドにアーム状のストッパ片を設けたことを特徴とする回路遮断器。
