この構成によれば、冷媒流路の流入口及び流出口が、端子接触部に対して後方を向いて開口しているので、これら流入口及び流出口に接続されて後方に延びる冷却チューブに発生する曲げを緩和できる。これにより、冷却チューブの曲げの復元力を低減して、冷却チューブとの接続部分からの冷媒漏れを抑制できる。また、端子本体部の側方に突出した端子拡張部に、冷媒流路の流入口及び流出口が形成されているので、後方を向いて開口した流入口及び流出口を端子本体部に設け易くなる。
また、この構成によれば、少なくとも冷媒流路が形成される端子本体部と端子拡張部の境界に、継ぎ目ないし割れ目などが存在しないので、端子の内部での冷媒漏れ及び電気抵抗の上昇を抑制できる。
この構成によれば、冷媒が熱伝導率の高い内壁面に接触することとなり端子の冷却効率を向上させることができる。
本発明の第3態様は、上記第2態様の端子において、前記冷媒流路が、前記端子本体部と一体で成形されていてもよい。
この構成によれば、冷媒に直接接触して直接冷却できるので端子の冷却効率をさらに向上させることができる。
この構成によれば、冷媒流路の流入口及び流出口が、端子接触部に対し斜め後方を向いて開口しているので、端子全体の最大幅寸法を小さくすることができる。これにより、給電コネクタのケースなどに端子を導入し易くなり、また、端子の母材を小さくすることができるため、コスト低減が可能となる。

なお、金属性の内壁面を有する冷媒流路2に絶縁性冷媒を流す場合、絶縁層や絶縁膜を形成した内壁面に比べて金属性の内壁面は熱伝導率が高いため、端子の冷却効率を向上させることができる。
また、冷媒流路2を、端子本体部10と一体で成形する場合、冷媒に直接接触して直接冷却できるので端子の冷却効率をさらに向上させることができる。別体で成形する場合に比べて、冷媒流路2と端子本体部10との隙間の空気の断熱作用を抑えられるためである。
