まず、図1及び図2を用いて、実施の形態に係る蓄電素子10の全般的な説明を行う。図1は、実施の形態に係る蓄電素子10の外観を示す斜視図である。図2は、実施の形態に係る蓄電素子10の容器100内に配置されている構成要素を示す斜視図である。具体的には、図2は、蓄電素子10を、容器100の蓋板110と容器本体101とを分離して示す斜視図である。
次に、本実施の形態に係る蓄電素子10における、電極端子の蓋板110への取り付け構造について、図3〜図6を用いて説明する。なお、本実施の形態では、電極端子200及び300それぞれの蓋板110への取り付け構造は共通している。そのため、以下では、負極側の電極端子200の蓋板110への取り付け構造について説明し、正極側の電極端子300の蓋板110への取り付け構造についての図示及び説明は省略する。
図7は、実施の形態の変形例1に係る上絶縁部材250aの構成概要を示す斜視図である。図7に示す上絶縁部材250aは、上記実施の形態に係る上絶縁部材250に換えて、端子本体201及び容器100の間に配置される部材である。本変形例に係る上絶縁部材250aには、軸部210(図3参照)が貫通する貫通孔252が形成されており、かつ、上絶縁部材250aは、端子本体201の端面202(図3参照)に沿って配置された側壁部251を有している。
図8は、実施の形態の変形例2に係る上絶縁部材250bの構成概要を示す平面図であり、図9は、実施の形態の変形例2に係る電極端子200aの構成概要を示す平面図である。
以上、本発明に係る蓄電素子について、実施の形態及びその変形例に基づいて説明した。しかしながら、本発明は、上記実施の形態及び変形例に限定されるものではない。本発明の趣旨を逸脱しない限り、当業者が思いつく各種変形を上記実施の形態または変形例に施したものも、あるいは、上記説明された複数の構成要素を組み合わせて構築される形態も、本発明の範囲内に含まれる。
