Abstract
Description
最初に、本開示の実施態様を列記して説明する。
本開示のコネクタは、
(1)取付対象に対向する対向面を有する合成樹脂製のハウジングと、前記ハウジングに収容された接続用端子と、電線の端末に接続されて前記ハウジングに収容された通電用導体と、前記ハウジングを覆う金属製のシールドシェルと、を備え、前記シールドシェルは、前記ハウジングの前記対向面を覆う延出部を有し、前記ハウジングは、前記接続用端子と前記通電用導体を締結する金属製の第1締結部材を収容する第1収容凹部と、前記ハウジングと前記シールドシェルの前記延出部を締結する金属製の第2締結部材を収容する第2収容凹部と、を有し、前記第1収容凹部と前記第2収容凹部が共通の樹脂壁を隔てて隣接している、コネクタである。
本開示の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、本開示は、これらの例示に限定されるものではなく、特許請求の範囲によって示され、特許請求の範囲と均等の意味およ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、本開示の実施形態1のコネクタ10について、図1から図10を用いて説明する。例えば、図1に示すように、コネクタ10は、取付対象であるインバータ等の機器12の筐体14に取り付けられて使用される。より詳細には、図4に示すように、コネクタ10の底面には、(後述する接続用端子34を構成する)一対の雌端子16,16が下方に向かって突出して設けられている。一方、図7に示すように、機器12の筐体14内には、機器側コネクタ18が設けられており、筐体14を貫通して設けられた挿通孔20を挿通して、機器側コネクタ18に設けられた一対の雄端子22,22が上方に向かって突出して設けられている。そして、コネクタ10が機器12の筐体14に取り付けられることにより、コネクタ10の雌端子16と機器12の雄端子22が接続されるようになっている。なお、コネクタ10は、任意の向きで配置することができるが、以下では、上下方向,左右方向,前後方向を、図中に示す上下方向,左右方向および前後方向を基準として説明する。また、複数の同一部材については、一部の部材にのみ符号を付し、他の部材については符号を省略する場合がある。
図7および図9に示すように、機器側コネクタ18は、一対の雄端子22,22と、一対の雄端子22,22を収容して機器12の筐体14内に固定される機器側ハウジング24を有している。
コネクタ10は、合成樹脂製のハウジング26を備えている。図5,図6および図8に示すように、ハウジング26は、コネクタ10が機器12の筐体14に取り付けられた際に取付対象である機器12の筐体14に対向する対向面28を有している。ハウジング26内には、電線を構成するシールド電線30の端末に接続された通電用導体32が収容されている。また、図9に示すように、ハウジング26内には、接続用端子34が収容されている。接続用端子34は、ハウジング26の対向面28側に配置されている。接続用端子34は、コネクタ10が機器12の筐体14に取り付けられた際に、機器側コネクタ18の雄端子22と嵌合して相互に接続されるようになっている。通電用導体32と接続用端子34は、後述するように、ハウジング26内で接続されている。さらに、コネクタ10は、ハウジング26の前方側を覆う金属製のシールドシェル36を備えている。
図5および図6に示すように、ハウジング26は、前後方向に長尺の略矩形状に構成されている。ハウジング26の後方側は、後述するようにシールドブラケット110によって覆われており、ハウジング26の前方側は、金属製のシールドシェル36によって覆われている。ハウジング26の前方側は箱形状に構成され、上方に開口する上方開口部38を有している。図2および図8に示すように、上方開口部38は、矩形平板状の蓋体40によって覆われている。蓋体40には、左右方向に対向する周縁部から下方に向かって突出する被係合枠体41が設けられている。被係合枠体41と、上方開口部38を構成する角筒状の周壁42の左右方向に対向する外周面に突設された突起部43と、が係合することにより、蓋体40がハウジング26の周壁42に対して固定されている。また、蓋体40の被係合枠体41の内側には、蓋体40の底面から下方に向かって垂れる環状の垂壁部44が形成されている。垂壁部44の外周面には環状のシール部材収容溝部45が形成されており、シール部材46が収容されることにより、蓋体40によりハウジング26の上方開口部38がシールされるようになっている。
図8および図9に示すように、シールドシェル36は、ハウジング26の前方側を覆うように配置されている。そして、シールドシェル36は、ハウジング26の対向面28を覆う延出部87を有している。延出部87には、後述する中間シールド部材102を収容する中間シールド部材収容孔88が貫設されている(図4,図9参照)。シールドシェル36は矩形箱形状を有しており、上方および後方に向かって開口している。図1等に示すように、シールドシェル36の上方側は、矩形平板状の金属製の蓋部89をボルト締めすることにより覆蓋されている。図1に示すように、左右方向に対向するシールドシェル36の一対の側壁90,90が前方側に延び出しており、延び出した一対の延出壁91,91の間に、固定部92が設けられている。図10に示すように、固定部92には、上下に離隔して形成された一対の固定壁94,94に対して、左右方向に離隔して一対のボルト挿通孔96,96が設けられている。また、図7に示すように、機器12の筐体14には、一対の有底円筒形状を有し、中央にそれぞれボルト挿通孔98を有する一対のボス100,100が上方に向かって突設されている。ボルト挿通孔96をボルト挿通孔98に位置合わせした後、固定部92をボス100に対してボルト101を締結して固定することにより、コネクタ10が機器12の筐体14に固定される。この結果、図10に示すように、シールドシェル36は、固定部92において機器12の筐体14に接続されている。
図8に示すように、シールドブラケット110が、ハウジング26の筒部72の外周面を覆うように配置されている。シールドブラケット110とハウジング26の筒部72の外周面間は、シール部材84によってシールされている。図4および図8に示すように、シールドブラケット110は、底面側において、前方に向かって矩形状に突出する突出部112を有している。この突出部112において、シールドブラケット110は、シールドシェル36に対してねじ留めされて接続されている。また、シールドブラケット110の後方側は、前方側に比べて小径とされている。この小径とされた部分において、シールドブラケット110と、シールド電線30のシールド部材である編組線76と、が金属製の押圧リング114によって径方向内方に押し付けられて固定されている。これにより、シールドブラケット110と編組線76が接続されている。以上の結果、シールド部材である編組線76がシールドシェル36の延出部87に接続されている。しかも、前述したように、シールドシェル36は、固定部92において機器12の筐体14に接続されている。
図9に示すように、まず雄端子22が上下方向に延出した状態で機器側ハウジング24に収容され保持された機器側コネクタ18を準備する。機器側コネクタ18の図示しない固定部を機器12の筐体14に対してボルト締結により固定する。次に、図5および図6に示すように、ハウジング26を準備する。ハウジング26から雌端子収容部58は取り外しておく。このハウジング26に対して、シールドシェル36を装着後、第2収容凹部68に対してボルト締結することによりシールドシェル36の延出部87をハウジング26の第2収容凹部68に収容されたナット66に接続する。これにより、ハウジング26に対してシールドシェル36が固定される。次に、雌端子収容部58内に、柔軟導体56および連結金具54が接続された雌端子16を収容する。続いて、雌端子収容部58をフード部64に収容し、ハウジング26の底壁48に突設された係合突部63に対して雌端子収容部58の被係合枠体60を係合することにより、所定位置に固定する。続いて、シールド電線30が接続された通電用導体32を後方側からハウジング26に挿入後、通電用導体32の先端部を連結金具54が載置された第1収容凹部52上に載置する。ここで、小径とされたシールドブラケット110の後端部は、シールドブラケット110と、シールド電線30のシールド部材である編組線76と、が押圧リング114により固定して接続されている。これにより、シールドブラケット110と編組線76が接続される。そして、シールドブラケット110を、ハウジング26の筒部72の外周面を覆うように配置後、シールドブラケット110の突出部112においてシールドブラケット110をシールドシェル36の延出部87に対してボルト締結して接続および固定する。これにより、シールド部材である編組線76がシールドシェル36の延出部87に接続される。
以上、本開示の具体例として、実施形態1について詳述したが、本開示はこの具体的な記載によって限定されない。本開示の目的を達成できる範囲での変形、改良等は本開示に含まれるものである。例えば次のような実施形態の変形例も本開示の技術的範囲に含まれる。

(3)上記実施形態1では、第1締結部材(ナット50)と第2締結部材(ナット66)は、対向面28と取付対象である機器12の筐体14の対向方向に交差する方向(前後方向)における投影で、ほぼ完全に重なり合っていたが、これに限定されない。第1締結部材(ナット50)と第2締結部材(ナット66)は、機器12の筐体14の対向方向に交差する方向(前後方向)における投影で、重なり合っていてもよいし、重なっていなくてもよい。
