Abstract
Description
最初に本開示の実施態様を列記して説明する。
本開示の充電コネクタの具体例を、以下に図面を参照しつつ説明する。なお、本発明はこれらの例示に限定されず、請求の範囲によって示され、請求の範囲と均等の意味および範囲内におけるすべての変更が含まれることが意図される。
以下、実施形態1にかかる電気接続ユニットについて説明する。図1は、電気接続ユニット10を示す概略図である。この電気接続ユニット10は、自動車内に設置されるものである。
以下、実施形態2にかかる電気接続ユニットについて説明する。図4は、電気接続ユニット210を示す概略図である。本実施形態の説明では、実施形態1との相違点が主に説明され、実施形態1との共通点については説明が省略されることがある。実施形態2においては、実施形態1の電気接続ユニット10に代えて、電気接続ユニット210が利用される。この電気接続ユニット210もまた、自動車内に設置される。
以下、実施形態3にかかる電気接続ユニットについて説明する。図6は、電気接続ユニット310に対して第1電源20、第2電源30および負荷装置40が接続される具体的構成例を示す概略図である。本実施形態の説明では、実施形態1との相違点が主に説明され、実施形態1との共通点については説明が省略されることがある。実施形態3においては、実施形態1の電気接続ユニット10に代えて、電気接続ユニット310が利用される。この電気接続ユニット310もまた、自動車内に設置される。
実施形態1および実施形態3の第2電源30が丸端子32と接続されるがこれに限定されない。第2電源30が、丸端子に代えてネジで締結可能なY型端子と接続されてもよい。つまり、第2電源30に接続される端子は、厚み方向に端子を貫通する貫通部を有する端子であればよく、貫通部は周りが囲まれた孔であってもよいし、端子の周縁部に達するスリット状の貫通部であってもよい。ただし、電源用接続部53との接続面積の広大化の観点からは、第2電源30に接続される端子は、丸端子であることが好ましい。
