改良された小型寸法の電気コネクタにして、キャビティ内の電気コンタクトに 嵌合され得るそれぞれのプラグに係合するために多数のプラグ受容キャビティ内 に延びるシールドを備える電気コネクタを提供することが望ましい。 本発明は、シールド型電気コネクタに関し、キャビティ内の電気コンタクトに 嵌合し得るそれぞれのプラグに係合する多数のプラグ受容キャビティ内に導電性 シェルが延びることによって小型寸法が実現される電気コネクタに関する。本発 明によれば、従来の電気コネクタに比較して部品数が減らされ、これにより組立 が簡略化され、製造コストが低減される。 本発明の利点は、多数のプラグ受容キャビティを完全に囲むシールドに関し、 そのシールドは外側シェルに係合する第2のシェルを含み、その第2のシェルは 小型の構成を実現するために多数のプラグ受容キャビティ内に延びる。

以下に添付図面を参照して、本発明の好適実施形態が示されるが、それにおい て、 図1は、部品が互いに分解された電気コネクタの斜視図であり、 図2及び図3は、図1のコネクタを後方及び前方より見た斜視図であり、 図4は、図1のコネクタを側方より見たコネクタの断面図であり、2つの嵌合 されるプラグ型電気コネクタが破線で示され、 図5は、図1に示されるコネクタの部品である絶縁ハウジングの斜視図であ り、 図6は、図1に示されるコネクタの部品である第2のシェルの斜視図であり、 図7は、図5に示されるハウジングを後方より見た斜視図であり、 図8及び図9は、図1に示されるコネクタの部品である導電性電気コンタクト の斜視図であり、 図10は、図5に示されるハウジングを後方から見た斜視図であり、図8及び 図9のコンタクトが共に示され、 図11は、図1に示されるコネクタの部品である外側の導電性シェルを前方か

のプラグ受容キャビティ3内の2列の電気コンタクト2、及びハウジング4を包 囲する外側導電性シェル6と外側シェル6の内側でプラグ受容キャビティ3内の 位置に置かれる第2の導電性シェル7とを含むシールド5を有する。例えばコネ クタ1は、2つのプラグ受容キャビティ3を含むように示される。図4に破線又 は点線で示されるように、それぞれの電気プラグコネクタ8は、コネクタ1に嵌 合されるために各プラグ受容キャビティ3に挿入され得る。プラグコネクタ8の 各々は絶縁オーバモールド10から突出する導電性シェル9を有する。図示され ないものの、プラグコネクタ8の各々は更にシェル9に囲まれる絶縁ハウジング 、及びコネクタ1のそれぞれのプラグ受容キャビティ3に挿入されてコネクタ1 のコンタクト2に係合されて電気的に接続されるハウジ ング内の相手電気コンタクトを有する。相手プラグコネクタ8の従来の構造は米 国特許第5,017,156号及び米国特許第5,2676,882号に開示さ れる。 図5、図7、及び図10を参照すれば、ハウジング4は一体的にモールドされ たプラスチックの構成から成る。ハウジングの隔壁11は2つのプラグ受容キャ ビティ3間で前方に延び、その背中合わせの面は各プラグ受容キャビティ3に面 する。キャビティ3は類似の形状を有し、一方のキャビティ3の形状は他方のキ ャビティ3の形状に対して反転した向きとされる。隔壁11に平行な第2の隔壁 12は、それぞれのプラグ受容キャビティ3を2つの部分に分離し、各キャビテ ィはシェル受容キャビティ部13とコンタクト受容キャビティ部14とに分離さ れる。 図8及び図9を参照すれば、電気コンタクト2が開示される。各コンタクト2 は一体の構造となるよう金属から打ち抜き折り曲げ形成される。湾曲した接触部 16が形成される片持ち梁状のばね15は、下方に曲げ形成される細長端子17 から前方に延長される。図8に示されるコンタクト2の端子部17は図9に示さ れるコンタクト2の比較的短い端子部17よりも長く形成される。ばね15の後 方の広幅の固定部18は突縁を有する。端子部17の広幅の固定部19は突縁を 有する。 図7及び図10を参照すると、多数のコンタクト受容通路20がハウジングの 後側から前方に延長され、上列及び下列を有するよう配置される。広幅のスロッ ト21は各通路20の頂側に沿って延びる。より長いコンタクト2は上側の列の 各通路20を延び、より短いコンタクト2は下側の列の各通路20に沿って延び る。コンタクト2の広幅部分18は、各スロット21に圧入係合されて、コンタ クト2を制止する。 各通路20の下側には、対応するコンタクト位置決めプレート22がハウジン グの他の部分から後方に突出する。細長の端子受容スロット23は、コンタクト 位置決めプレート22の各々の後側に形成される。上側のプレート22のスロッ ト23は、下側のプレート22の各スロット23に位置合わせされる。コンタク ト2の端子17は各通路20から後方に延び、対応するスロット23を通して下 側に延長される。コンタクト2のより短い端子部17は下側のプレート22の対 応スロットを通して延び、より長い端子部17は両プレート22のスロット23 を通して延びる。このように下側プレート22の各スロット23は2つの端子1 7を受容する。よって、端子17は図示されない回路基板の開口を通して実装さ れるためにプレート22によって位置合わせされる。各端子部17の広幅部19 は下側プレート22の対応スロット23内に圧入され、端子17を移動しないよ うに保持する。 図4及び図13によれば、各電気コンタクト2上の湾曲接触部15は通路20 に沿って延びる。通路20は各プラグ受容キャビティ3に開口し、それぞれの隔 壁12に沿って溝を形成する。接触部15は溝に沿って延びコンタクト受容キャ ビティ14に面する。 図4、図6、図10及び図12によれば、第2の導電性シェル7は厚さを有す る金属シートの打ち抜き折り曲げにより形成される一体構造を成し、よって金属 シートの厚さは第2のシェル7の板厚を形成する。第2のシェル7は、曲げられ た角部25で各ウエブ26に結合される離間されたプレート24を含み、ウエブ 26はプレート24から横方向に延びる。開いたシーム27は対応するプレート 24からウエブ26の一つを分離する。プレート24は図4及び図7に示すよう にハウジング4内に離間されたスロット28に沿って摺動して装着される。スロ ット28はハウジング4内を後から前へと延びる。図2に示され るように、第2のシェル7は上列のコンタクト2の端子部17より前方に位置す る。このように、第2のシェル7はそれらのコンタクト2がハウジング4に組み 立てられる前にハウジング4に組み付けられる。片持ち梁状ラッチ指29は各プ レート24に後方に向けて突出し、プレート24の板厚方向に打ち出される。プ レート24が離間されたスロット28に沿って挿入されるとき、ラッチ指29は 弾性的に撓み、各スロット28に受容されるとき外方に戻される。ラッチ指29 は図4及び図12に示すように各スロット28内で後壁30に面し、第2のシェ ル7のハウジング4に対する後方への移動を阻止する。 第2のシェル7のプレート24は、ハウジング4の隔壁11に沿って摺動して 装着され、それに沿って位置決め固定される。更に、第2のシェル7のプレート 24は、隔壁11の背中合わせの面上を延びる。片持ち梁状ばね指31は各プレ ート24から前方に突出する。第2のシェル7上のばね指31はプレート24か ら前方に延びて、各プラグ受容キャビティ3内を延長され、プラグ受容キャビテ ィ3内に受容される各プラグ型電気コネクタ8に係合される。ばね指31の各々 は隔壁11に窪んで形成された対応する窪み部33内を延びる湾曲端部32を有 する。端部32は対応するプラグ受容キャビティ3に沿って延び、プラグ受容キ ャビティ3内に受容される各プラグ型電気コネクタ8に接触すべく、対応するプ ラグ受容キャビティ3に沿って延びる。第2のシェル7のばね指31は、各プラ グ受容キャビティ3内の電気コンタクト3とともに各プラグ受容キャビティ3内 を延び、これによりプラグ受容キャビティ3に受容されるためのプラグ型電気コ ネクタ8は、第2のシェル7のばね指31及び電気コンタクト2に係合接続され る。 図4によれば、各プラグ8は対応する接触部14に入り、対応するコンタクト 列内のコンタクト15に接触する。プラグコネクタ8の導電性シェル9は、 接触部14及び同じプラグ受容キャビティ13の対応するシェル受容部13に入 る。 図2、図3、図11及び図12によれば、導電性を有する外側シェル6は厚さ を有する金属シートの打ち抜き折り曲げにより形成される一体構造を成し、よっ て金属シートの厚さは外側シェル6の板厚を形成する。外側シェル6は曲げられ た角部35で結合される4つの壁34を有し、壁34の一つは開いたシーム36 で分離される。4つの壁34は外側シェルの開口前端を囲むよう形成され、各壁 34上の外方に曲げられたリップ37が前端に近接して置かれる。 ハウジング4及び外側シェル6は、図2及び図3の如くラッチ38によりラッ チ係合されるが、ラッチ38はくさび形状に突出するハウジング4の突起40を 受容するために外側シェル6の対応壁34に開口39を有する。突起40は前か ら後の方向に傾斜し、よって突起40は外側シェル6の開口後端に押し入れられ 、対応壁34の開口39にラッチ係合される。 スロット開口41は、図2及び図3の如く対応する対向壁34を後から前に延 び、外側シェル6の開口後端に連通する。ハウジング4の対向壁から突出する細 長リブ42は、ハウジング4に対する外側シェル6の回動を防止すべくスロット 開口41に沿って延びる。リブ42は、ハウジング4が開口後端に挿入されると きに後からスロット開口41に入れられる。 外側シェル6の4つの壁34は、外側シェル6の開口後端を囲むよう置かれる 。図11に示すように、シーム36によって分離される壁34は、後側開口43 を有する。開口43を形成するために金属を切除するのでなく、開口43を形成 するために除去されるべき金属は、開口43に位置合わせされる細長電気端子部 44とされる。端子部44は対応する対向壁34に結合され、それらから突出す る。端子部44はコネクタ1が実装されるための図示されない回路 基板の開口に接続される。図4及び図5に示すように、ハウジング4上の肩45 は前方に面し、開口43に受容され、ハウジング4が外側シェル6に対して前方 に移動するのが阻止される。ハウジング4は肩45がハウジング43の端に面す るまで外側シェル6の開口後端内に挿入される。 外側シェル6の4つの壁34の各々のばね指46は、外側シェル6の開口前端 に近接する。各ばね指46は、外側シェル6内部へと突出する湾曲片47を含む 片持ち梁状ビームとされる。対応する対向壁34上のばね指46は前から後へと 延びる。対応する他の対向壁34部分のばね指46は後から前へと延びる。各ば ね指46は外側シェル6の板厚から曲げ出され、壁34の内側に突出される。図 4を参照すれば、分離された壁34のばね指46は、前方に面し、対応するプラ グ受容キャビティ3に沿って、コンタクト受容部14に沿って延びる。対向壁3 4のばね指46は、他のプラグ受容キャビティ3のシェル受容部13に受容され るが、シェル受容部13は外側シェル6とハウジング4の対応する外側壁との間 に位置する。図4及び図13に示されるように、シェル受容凹部13は各隔壁1 2の側部上に延びる。分離された壁を結合する2つの壁34の各々のばね指46 は、シェル受容凹部13に沿って延び、更に各隔壁12の側部を延びる。ばね指 46は、プラグコネクタ8がコネクタ1に嵌合されるためにプラグ受容キャビテ ィ3内に受容されるとき、各プラグコネクタ8のシェル9に係合する。このよう に、外側シェル6及び第2のシェル7の互いの係合、及びプラグコネクタ8の各 シェル9との係合により電気接続が効果的に行われる。 図2、図3、図10及び図12によれば、第2のシェル7はハウジングの凹部 48を橋渡しするように置かれる。外側シェル6は凹部48内に突出し、第2の シェル7に係合する。更に詳細には、外側シェル6の各側壁34上の追加 のばね指49が外側シェル6の後端に近接し、ばね指46に類似の構造を有する よう設けられる。外側シェル6の追加のばね指49は、第2のシェル7上の各ウ エブ26に係合するようハウジング4の凹部48内に延出し、これにより第2の シェル7は外側シェル6に係合し、両者間の電気接続を実現できる。 本発明の効果は、多数のプラグ受容キャビティを完全に囲むシールドにあり、 そのシールドは外側シェルに係合する第2のシェルを有し、第2のシェルは小型 の構成を実現するために多数のプラグ受容キャビティ内部に延びる。 他の効果はシールドにあり、それは外側シェルに係合接続される第2のシェル を有し、外側シェルと第2のシェルの両方はコネクタの多数のプラグ受容キャビ ティの各々の内部を延び、外側シェル及び第2シェルの両方がプラグ受容キャビ ティに受容される電気プラグコネクタの各々に係合接続可能とされる。DETAILED DESCRIPTION OF THE INVENTION Shielded electrical connector The present invention
