Description
18はシングルトーション形のねじりコイルバネ、すなわち復帰スプリングであり、密着巻きされたコイル部18aと、一対の足18b,18cを有し、アーマチュア16と固定マグネット13との間に係合し、常時はアーマチュア16を固定マグネット13から引き離す方向に付勢している。
18 single torsion type of the torsion coil spring, that is, the return spring, a coil portion 18a which is tightly wound, a pair of
上記のように構成された回路遮断器においては、図3において、過負荷電流が電源側端子20→固定接触子21→可動接触子22→可撓導体23→接続導体24→ヒータ取付部12c→ヒータ部12b→負荷側端子12aの経路で流れると、ヒータ部12bの発熱でバイメタル14が加熱され、バイメタル14の先端部14aが図3に示すように、矢印A方向に湾曲する。この湾曲により、バイメタル14の先端部14aでトリップバー25aを押し、開閉機構部25が動作して回路遮断器をトリップさせる。
In the circuit breaker configured as described above, in FIG. 3, the overload current is the power supply side terminal 20 → fixed contact 21 →
次に、アーマチュア16の第二のばね掛け部16fに仮掛止されている復帰スプリング18の他方の足18cを、指またはピン等で第二のばね掛け部16fから外すと、自動的に復帰スプリング18の他方の足18cは固定マグネット13のばね係合部13bに係合し、アーマチュア16の可動片16aは復帰スプリング18の付勢力でケース10のストッパ10c(図1に示す)に当接して、所定の取付け位置に組込まれる。
