Description
図1は、本実施形態に係る接点部材としての固定接点10を備える摺動接点1を示す模式図である。摺動接点1は、固定接点10と、固定接点10との接触・非接触を切り替え可能な可動接点2とを備える。
次に、本実施形態に係る接点部材としての固定接点10の製造方法について説明する。なお、以下では、メッキにより表面層12を形成する製造方法について説明するが、表面層12を形成する方法はこれに限られるものでは無く、例えば、溶射等により形成してもよい。
固定接点10の耐アーク性の評価を行った。具体的には、まず、導電性基体11として、銅合金を、母材13としてパラジウム合金を、基材粒子14aとして酸化亜鉛を、被覆層14bとして二酸化ケイ素を用いた固定接点10を作成した。そして、作成した固定接点10を備える摺動接点1を用い、15V、1Aの電流を流した状態で開閉操作を行い、摺動接点1の操作回数と、操作した際のアークの発生時間との関係を測定した。また、比較のため、表面層12中に分散粒子14を含まない従来品についても、摺動接点1の操作回数と、操作した際のアークの発生時間との関係を測定した。測定結果を図3に示す。
次に、本実施形態に係る摺動接点の適用例について説明する。図4の(a)は、摺動接点を備えるスイッチ(電気機器)100の構成を示す概観斜視図であり、図4の(b)は、スイッチ100の部分拡大図である。なお、実際には、スイッチ100の少なくとも一部は、図示しないケースに収容されている。
