Description
これにより、締結ボルトと第1のナットとの締結時に締付力によって第1の貫通孔周辺が変形するのを抑制し、絶縁部材を固定部材に強固に取付けることができる。
これにより、第2の貫通孔の内周面にネジ部を容易に構成することができる。
図1は、本開示の実施の形態1に従う接続部材が用いられる組電池を搭載した電動車両1の全体構成を示した図である。なお、以下では、電動車両1が電気自動車(EV(Electric Vehicle))である場合について代表的に説明するが、本開示に従う接続部材が用いられる組電池は、EVに搭載されるものに限定されず、ハイブリッド車両(HV(Hybrid Vehicle))やプラグインHV等の組電池を搭載した車両全般、さらには車両以外の用途にも適用可能である。
上記の実施の形態1では、接続部材200を固定部材50から取外す場合に、ボルト252の先端部が固定部材50に押付けられるので、固定部材50が摩耗し得る。そこで、この実施の形態2では、固定部材50の摩耗を防止するための対策が採られる。
絶縁部材205を固定部材50から取外す場合に固定部材50が摩耗するのを防止するための構成は、上記のような構成を有する摩耗抑制板300に限定されるものではない。たとえば、図9に示されるように、上記の摩耗抑制板300に代えて、絶縁部材205に形成される貫通孔250の下方に、クリップ構造等により固定部材50の上面に取付けられる摩耗抑制板310を設けてもよい。
上記の各実施の形態においては、接続部材200(200A)が固定部材50に取付けられる場合に、接続部材200(200A)に設けられるバスバー210の両端部が差込み式のコネクタ40に挿入されることによってバスバー210とモジュールから延びるバスバー30とが電気的に接続されるものとしたが、バスバー210とバスバー30との接続構造は、このようなコネクタに限定されるものではない。
