Abstract
Description
最初に本開示の実施態様を列記して説明する。
本開示のグロメットユニット及びワイヤハーネスの具体例を、以下に図面を参照しつつ説明する。なお、本開示はこれらの例示に限定されるものではなく、請求の範囲によって示され、請求の範囲と均等の意味及び範囲内での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にかかるグロメットユニット及びこれを備えるワイヤハーネスについて説明する。図1は実施形態1にかかるグロメットユニット60及びこれを備えるワイヤハーネス10を示す斜視図である。図2は実施形態1にかかるグロメットユニット60及びこれを備えるワイヤハーネス10を示す底面図である。図3は図2のIII-III線に沿った断面図である。図4は図3の領域Aの拡大図である。
ワイヤハーネス10は、コネクタ20と配線部材50とグロメットユニット60とを備える。コネクタ20は、相手側コネクタと接続される接続部分を有する。配線部材50はコネクタ20における端子40と接続されて、コネクタ20から外方に延びている。グロメットユニット60は、グロメット62と、障壁部材80とを備える。グロメット62は、コネクタ20及び配線部材50の一部を覆う。障壁部材80は、グロメット62に取付けられている。本例では、コネクタ20がインレット20である例が説明される。コネクタ20は、インレット20である必要は無く、車両に搭載される如何なるコネクタであってもよい。
ここではインレット20は、上記接続部分と固定部28とを有する。固定部28は、車両への固定に用いられる部分である。ここでは、複数の部品が組み合わされてインレット20における接続部分及び固定部28が構成されている。インレット20は、かかる複数の部品として、第1部材22と第2部材32と端子40とを備える。
グロメットユニット60におけるグロメット62について、図1から図6に加えて図7を参照しつつ説明する。図7はグロメット62を示す斜視図である。
障壁部材80について、図1から図7に加えて図8から図10を参照しつつ説明する。図8は障壁部材80を示す斜視図である。図9は障壁部材80を示す一方側面図である。図10は障壁部材80を示す他方側面図である。
以上のように構成されたグロメットユニット60及びこれを備えるワイヤハーネス10によると、障壁部材80が排水筒部69の内部の排水路を部分的に塞ぐことによって、排水路において、グロメット62の内部の水が排水可能である状態に保たれつつ、グロメット62の外部の塵等が侵入困難な状態となることができる。障壁部材80は、グロメット62及びコネクタ20とは別に成形された部材であるため、グロメット62及びコネクタ20において構造の変更が必須でなくなる。これらより、グロメット62及びコネクタ20の構造の複雑化を抑制しつつ、排水筒部69からの塵等の侵入を抑制できる。
これまで、障壁部材80は、少なくとも1つの側壁82と、少なくとも1つの仕切84とを有するものとして説明されたが、このことは必須の構成ではない。例えば、障壁部材80は、1つの仕切84のみを有する形状に形成されていてもよい。つまり、障壁部材80は、平板状に形成されて、表面の法線方向がZ方向と交差する方向となるように、排水筒部69の内部に配置されていてもよい。
上記例では、グロメット62に障壁部材80が取付けられるものとして説明されたが、グロメット62に障壁部材80が取付けられずに、グロメット62の排水筒部69に直接的に仕切84が設けられてもよい。つまり、グロメットは、本体部63、排水筒部69及び仕切84を有する形状に金型一体成形されていてもよい。
