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18,18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 legs 18 b, 18 c, engagement between the armature 16 and the stationary magnet 13, At all times, the armature 16 is urged in the direction of pulling it away from the fixed magnet 13.

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 → movable contact 22 → flexible conductor 23 → connecting conductor 24 → heater mounting portion 12c → When the current flows through the path from the heater portion 12b to the load side terminal 12a, the bimetal 14 is heated by the heat generated by the heater portion 12b, and the tip portion 14a of the bimetal 14 is curved in the direction of arrow A as shown in FIG. Due to this curvature, the trip bar 25a is pushed by the tip portion 14a of the bimetal 14, and the opening / closing mechanism portion 25 operates to trip the circuit breaker.

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13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。 Next, when the other foot 18c of the return spring 18 temporarily hooked on the second spring hook 16f of the armature 16 is removed from the second spring hook 16f with a finger or a pin or the like, the armature 16 automatically recovers. other leg 18c of the spring 18 engages the spring engaging portion 13 b of the stationary magnet 13, the movable piece 16a of the armature 16 against the stopper 10c of the case 10 by the biasing force of the return spring 18 (shown in FIG. 1) It comes into contact and is installed in the specified mounting position.
