Claims (1)
- 入出力に対応した一対の端子部と、固定接点を有し一方の端子部と接続される端子板と、固定接点と接離する可動接点を有し他方の端子部と接続される可動接触子とが一乃至複数の極毎に器体に収納され、各極の可動接触子を所定の間隔を空けて保持し且つ各可動接点が各固定接点に接触した際の接圧を付与する接圧ばねを内部で保持する複数の保持部を軸部で互いに連結して成り、各可動接触子を連動して動作させるクロスバーと、オン位置とオフ位置との間で回動自在なハンドルを有するとともにハンドルの回動動作をクロスバーに伝達することにより各可動接点を各固定接点に接離させる複数のリンク部材から成る開閉機構と、開閉機構の均衡を崩す方向の勢力を蓄積した状態で開閉機構の均衡を保持するラッチ部材と、固定接点および可動接点間に過電流が流れるとラッチ部材を駆動して開閉機構の均衡を崩し、可動接点を固定接点から強制的に開極させる過電流遮断機構とを備えた接点装置であって、クロスバーは、自身に設けられた軸部を軸として可動接点が固定接点と接触する位置と離れる位置との間で回動自在であって、端子板は、接点の接離方向と略平行で且つ各接点と対向する延出片を有し、延出片には、可動接点の動作範囲と対向する位置に強制開極時に発生するアークガスを逃がし、且つクロスバーの軸部に向かう方向の電磁気力を弱めるための逃がし孔が設けられたことを特徴とする接点装置。
