Description
たとえば、レーザ溶接などによる溶接には、バスバーと対応するセル端子との間に十分な物理的接触が必要である。しかし、製造位置公差の蓄積によりセル端子が異なる垂直位置にあるときには問題が生じる。剛性のバスバーを有することも、バスバーの一方の側を下方に押して対応する端子に押し付けるとき、バスバーの他方の側が対応するセル端子から持ち上げられることがあるため、問題である。
別法として、バスバー130および電池セル端子120、122は、異なる金属から製造することができる(たとえば、バスバー130をアルミニウムとし、電池セル端子120、122を銅とする)。任意選択で、バスバー130は、たとえば、一部分をアルミニウム(またはアルミニウム合金)とし、一部分を銅(または銅合金)とするなど、バイメタルとすることができる。
端子タブ134、136を独立して位置決め可能にすることで、端子タブ134、136を電池セル端子120、122に対して適切に位置決めすることが可能になる。例示的な実施形態では、基部132は、端子タブ134、136の独立した動きを可能にするように可撓性を有する。
したがって、第1の端子タブ134は、第1の脚部140および可撓継手144の前方に位置決めされる。第2の端子タブ136は、第1の脚部140および可撓継手144の前方に位置決めされる。端子タブ134、136は、第1の脚部140の前方に位置決めされることに加えて、またはその代替として、第2の脚部142の前方に位置決めすることができる。
終端部194は、圧接接続などによって、回路モジュール108のワイヤにはんだ付け、圧着、または他の形で終端させることができる。終端部194は、バスバー130にカチッと嵌めることができる端子とすることができる。終端部194は、バスバー130に直接終端させることができるワイヤとすることができる。
たとえば、ワイヤ198は、回路モジュール108の回路基板にプレス嵌めすることができる。ワイヤ198は、回路モジュール108の回路基板にはんだ付けすることができる。ワイヤ198は、回路モジュール108(図9参照)のワイヤにはんだ付け、圧着、または他の形で終端させることができる。
