Claims (6)
- スイッチの過熱破壊式電力切断方法であって、
第1弾性部材の第1弾性力が操作部材を介して過熱破壊部材と可動導電部材に同時に付勢し、該第1弾性力の付勢方向が、該可動導電部材を第1導電部材と第2導電部材に同時に接触させる方向であり、電流通路を形成することができる工程と、
第2弾性部材の第2弾性力が該操作部材を介して該可動導電部材に作用し、該第2弾性力の付勢方向が該可動導電部材を該第1導電部材または該第2導電部材から遠ざける方向である工程と、
該可動導電部材が該第1導電部材と該第2導電部材に同時に接触するとき、該過熱破壊部材が電流の伝達に必要な経路以外に設置され、かつ該過熱破壊部材が該可動導電部材から離れた位置に設置され、該電流の伝達に必要な経路以外で、該過熱破壊部材が該電流通路の熱エネルギーを受け取ることができる工程と、
該電流通路の熱エネルギーが、順に該可動導電部材、該第1弾性部材を経由して、該過熱破壊部材に伝達される工程と、
該過熱破壊部材が該熱エネルギーを受け取り、温度が上昇して破壊温度に近付くと、該第1弾性力の付勢により、該過熱破壊部材が破壊または変形され、それに伴い該第1弾性部材に変形が生じ、これにより該可動導電部材に作用する該第1弾性力の付勢が小さくなるか失われ、該第2弾性力により該可動導電部材の位置が変化し、該可動導電部材が該第1導電部材と該第2導電部材を同時に導通しなくなり、該電流通路が中断される工程と、
を含むことを特徴とする、スイッチの過熱破壊式電力切断方法。 - 前記過熱破壊部材の破壊温度が100℃〜400℃の間であることを特徴とする、請求項1に記載のスイッチの過熱破壊式電力切断方法。
- 前記過熱破壊部材がプラスチック材料で製造されることを特徴とする、請求項2に記載のスイッチの過熱破壊式電力切断方法。
- 前記過熱破壊部材が金属または合金で製造されることを特徴とする、請求項2に記載のスイッチの過熱破壊式電力切断方法。
- 前記合金の主要成分が、ビスマス、カドミウム、錫、鉛、ジスプロシウム、インジウムのうちいずれか2種類以上を含むことを特徴とする、請求項4に記載のスイッチの過熱破壊式電力切断方法。
- 前記合金が、錫ビスマス合金である、または錫とビスマス中にさらに、カドミウム、インジウム、銀、錫、鉛、アンチモン、銅のいずれか、または組み合わせが添加されることを特徴とする、請求項4に記載のスイッチの過熱破壊式電力切断方法。
