前記第1クリップ端子ユニットと前記第2クリップ端子ユニットとの間に前記相対接続端子が挿入されて一部分に前記相対接続端子が接触する接続部と、
前記接続部から延び、前記端子ハウジングの側壁によって支持されるように構成された支持部と、を備える。
前記バッテリー管理ユニットに備えられた印刷回路基板を貫通するように前記本体部から延びたリードと、を備え得る。
前記第1クリップ端子ユニットの左側に位置した左側壁と、
前記第2クリップ端子ユニットの右側に位置した右側壁と、
前記第1クリップ端子ユニット及び前記第2クリップ端子ユニットの後側に位置する後側壁と、を備え得る。
前記接続部と一体で連結され、前記相対接続端子を基準で両側に位置し、前記端子ハウジングに固定されるように構成された固定部と、

前記接続部は、バネ力によって前記相対接続端子と接触し得る。
また、本発明の一実施例によると、コネクターが端子ハウジングの側壁によって支持されるように第2延長構造から後方へ曲げられて延びた第3延長構造を備えることで、支持部の第3連結構造によって相対接続端子が挿入される力を効果的に相殺することができる。また、第3連結構造は、側壁に密着してコネクターに発生した熱を効果的に端子ハウジングへ伝達できる。これによって、コネクターの放熱性能を高めることができる。
