Abstract
Description
第1実施形態に係るアース接続構造について、図面を参照しながら説明する。
第1実施形態に係るアース接続構造100が用いられる車両1の概略構成について、図1を参照しながら説明する。車両1は、自動車(電気自動車、ハイブリッド電気自動車等を含む)であるものとする。
第1実施形態に係るアース接続構造100の構成について、図2(a)、2(b)、3を参照しながら説明する。
低インダクタンス材130Aと公知の単芯丸型電線とを導通連結部130に使用した場合の比較評価について、表1を参照しながら説明する。
第1実施形態では、導通連結部130は、低いインダクタンスを有する低インダクタンス材130A、すなわち、背景技術で説明した導通連結部(電流容量により径が設定される単芯丸型電線)よりも低いインダクタンスを有する低インダクタンス材130Aによって構成される。このため、低インダクタンス材130Aによりインピーダンスを小さくすることができるので、特に、高周波数の交流電流成分に対する低インピーダンス化を実現できる。導通連結部130の低インピーダンス化によって電位降下が生じ難く、電位降下の作用によってノイズ電圧が上昇してしまうことを抑制でき、電位上昇に起因するノイズを抑制することができる。その結果、車両に搭載される電装機器へのノイズによる悪影響(電装機器が不安定になることや機能しないこと)を防止することができる。
第1実施形態に係るアース接続構造100の変更例について、図4を参照しながら説明する。なお、第1実施形態に係るアース接続構造100と同一部分には同一の符号を付して、相違する部分を主として説明する。
第2実施形態に係るアース接続構造について、図面を参照しながら説明する。なお、第1実施形態に係るアース接続構造100と同一部分には同一の符号を付して、相違する部分を主として説明する。
第2実施形態に係るアース接続構造100Aの構成について、図5―9を参照しながら説明する。
第2実施形態では、ワッシャー140は、ボディBD側に向けて突出する突起142を備える。突起142がボディBDの塗装(カチオン塗装面)や錆止め等の外装Eを削り取るため、ワッシャー140とボディBDとの導通性が向上する。このため、ボディBDの外装Eが削られない場合と比較して、ワッシャー140とボディBDの地金との間(ボルトB周辺)おける電気抵抗が小さくなり、特に、直流電流成分に対する電気抵抗が小さくなる。このため、ボルトB周辺で生じる電位降下の作用によってノイズ電圧が上昇してしまうことを抑制でき、電位上昇に起因するノイズを抑制することができる。
第2実施形態に係るアース接続構造100Aの変更例について、図10を参照しながら説明する。なお、第2実施形態に係るアース接続構造100Aと同一部分には同一の符号を付して、相違する部分を主として説明する。
第3実施形態に係るアース接続構造について、図面を参照しながら説明する。なお、上述した第1実施形態に係るアース接続構造100や第2実施形態に係るアース接続構造100Aと同一部分には同一の符号を付して、相違する部分を主として説明する。
第3実施形態に係るアース接続構造100Bの構成について、図11―14を参照しながら説明する。
第3実施形態では、ワッシャー140に、防水パッキン140Aが設けられる。これにより、ワッシャー140の内周側に水などの液体が侵入することなく、突起142によってボディBDの塗装(カチオン塗装面)や錆止め等の外装Eが削り取られた箇所へ液体が付着することを防止できる。このため、ボディBDの外装Eの耐久性を向上させることができる。
第4実施形態に係るアース接続構造について、図面を参照しながら説明する。なお、第1実施形態に係るアース接続構造100、第2実施形態に係るアース接続構造100A、第3実施形態に係るアース接続構造100Bと同一部分には同一の符号を付して、相違する部分を主として説明する。
第4実施形態に係るアース接続構造100Cの構成について、図15、16を参照しながら説明する。
第4実施形態では、複数本のアース電線20のうちのノイズ発生源とされるアース電線20に取り付けられる磁性体のフェライト180を備える。これにより、高周波数の電流が接続金具150に流入することを阻止でき、接続金具150内の電位差を抑制することができる。このため、接続金具150内での電位上昇を抑制でき、ボディBDの電位により近づいた電位にすること(すなわち、接続金具150とボディBDとの間を等電位化すること)ができる。従って、電位上昇に起因するノイズを抑制することができる。
上述したように、本発明の実施形態を通じて本発明の内容を開示したが、この開示の一部をなす論述及び図面は、本発明を限定するものであると理解すべきではない。この開示から当業者には様々な代替実施の形態、実施例及び運用技術が明らかとなる。
