Description

本発明は、電磁波の侵入や放射を防止するシールド付きコネクタに係り、更に詳しくは、コネクタの嵌合構造に関するものである。   The present invention relates to a shielded connector for preventing electromagnetic waves from entering and radiating, and more particularly to a connector fitting structure.

従来、シールド付きコネクタ１５は、図６乃至図７に示すように、レセプタクルコネクタ１６とプラグコネクタ１７とも、内側にコンタクト１６ａ，１７ａを配設し、その外側を囲うように、金属製シールド用のシェル１６ｂ，１７ｂが囲ってあり、外側に嵌合用の合成樹脂製の外壁１６ｃ，１７ｃがある。   Conventionally, as shown in FIG. 6 to FIG. 7, the shielded connector 15 has contacts 16a and 17a disposed on the inside of the receptacle connector 16 and the plug connector 17 so as to surround the outside thereof. Shells 16b and 17b are enclosed, and outer walls 16c and 17c made of synthetic resin for fitting are provided outside.

上記レセプタクルコネクタ１６とプラグコネクタ１７とが嵌合して、コンタクト１６ａ，１７ａの接続を図ると共に、シェル１６ｂ，１７ｂ同士が電気的に接続されてシールド効果が発揮される（特許文献１参照）。
特開平９−１７５１３号公報 The receptacle connector 16 and the plug connector 17 are fitted to connect the contacts 16a and 17a, and the shells 16b and 17b are electrically connected to each other so that a shielding effect is exhibited (see Patent Document 1).
Japanese Patent Laid-Open No. 9-17513

しかし、従来のシールド付きコネクタ１５では、図８に示すように、レセプタクルコネクタ１６側のシェル１６ｂと外壁１６ｃと、プラグコネクタ１７側のシェル１７ｂと外壁１７ｃとが、互いに交互に重畳されるようになっているので、部材の厚さが積み重なって、レセプタクルコネクタの全体の外形寸法が大きくなってしまう。即ち、図８に示すように、シェル１７ｂがレセプタクルコネクタ１６側のシェル１６ｂに嵌合されると、前記シェル１６ｂの一部が接触バネになっており、そのバネの突起部１６ｄにより、外側に撓むことになる。その撓み分がＣ２寸法である。よって、シェル１７ｂの外側を囲撓する絶縁体１７ｃは、前記撓み分Ｃ２とレセプタクルコネクタ１６側のシェル１６ｂの板厚Ｄ寸法を重ねた分を避けねばならない。これにより、外壁１７ｃが大きくなり、それを受け入れて嵌合するレセプタクルコネクタ１６側の外壁１６ｃの幅も大きくなってしまう。本発明に係るシールド付きコネクタは、このような課題を解決するために提案されたものである。   However, in the conventional shielded connector 15, as shown in FIG. 8, the shell 16b and the outer wall 16c on the receptacle connector 16 side, and the shell 17b and the outer wall 17c on the plug connector 17 side are alternately superimposed on each other. Therefore, the thickness of the members is stacked, and the overall outer dimensions of the receptacle connector are increased. That is, as shown in FIG. 8, when the shell 17b is fitted into the shell 16b on the receptacle connector 16 side, a part of the shell 16b becomes a contact spring, and the protrusion 16d of the spring moves outward. It will bend. The amount of deflection is the C2 dimension. Therefore, the insulator 17c surrounding and bending the outside of the shell 17b must avoid the overlap between the bending portion C2 and the thickness D of the shell 16b on the receptacle connector 16 side. As a result, the outer wall 17c becomes larger, and the width of the outer wall 16c on the receptacle connector 16 side that receives and fits the outer wall 17c also becomes larger. The shielded connector according to the present invention has been proposed in order to solve such problems.

本発明に係るシールド付きコネクタの上記課題を解決して目的を達成するための要旨は、レセプタクルコネクタの接続部における中心部にコンタクトと、該コンタクトの周囲を囲撓する金属製シェルと、該シェルの外側を囲撓する絶縁体とが夫々配設され、これに嵌合するプラグコネクタにおいてはその接続部における中心部にコンタクトと、前記レセプタクルコネクタ側のシェルの内側に嵌合する金属製シェルと、該シェルを囲撓すると共に前記レセプタクルコネクタ側の絶縁体の内側に嵌合する絶縁体とが夫々配設され、当該レセプタクルコネクタとプラグコネクタとを嵌合させるシールド付きコネクタにおいて、前記プラグコネクタ側の筒状の絶縁体が前記シェルと組立用の所定の間隙を有するとともに前記レセプタクルコネクタ側のシェルにおける接触バネ用の撓み分の間隙を設けずに形成され、且つ、この絶縁体の板厚の寸法を前記レセプタクルコネクタ側のシェルの板厚分と該シェルにおける接触バネの撓み分との合計寸法以上とし、当該プラグコネクタ側の絶縁体の一部に、前記レセプタクルコネクタ側の接触バネが嵌合時に入り込んでプラグコネクタ側のシェルに接触するように当該シェルを露出させる切欠き部を設けたことである。   SUMMARY OF THE INVENTION The gist for solving the above-mentioned problems of the shielded connector according to the present invention is to provide a contact at the center of the connecting portion of the receptacle connector, a metal shell that surrounds the periphery of the contact, and the shell. In the plug connector fitted to each of the insulators, a contact is formed at the center of the connecting portion, and a metal shell is fitted inside the shell on the receptacle connector side. An insulator that surrounds the shell and fits inside the insulator on the receptacle connector side, and a shielded connector that fits the receptacle connector and the plug connector on the plug connector side. The cylindrical insulator has a predetermined gap for assembly with the shell, and is provided on the receptacle connector side. The gap of the contact spring in the shell is formed without providing a gap, and the thickness of the insulator is determined by the thickness of the shell on the receptacle connector side and the deflection of the contact spring in the shell. Provide a notch that exposes the shell so that the contact spring on the receptacle connector side enters when contacting the plug connector side shell and contacts the shell on the plug connector side in part of the insulator on the plug connector side. That is.

本発明のシールド付きコネクタによれば、プラグコネクタ側の絶縁体の切欠き部によりレセプタクルコネクタ側のシェルの接触バネを受け入れると共に、プラグコネクタ側のシェルとの嵌合で外側に撓む前記接触バネの板厚分と撓み分とが、当該プラグコネクタ側の絶縁体における切欠き部の板厚の範囲内で収められて、該絶縁体とシェルとの間に間隙が不要となりプラグコネクタの全体寸法が従来よりも小さくできる。よって、これと嵌合するレセプタクルコネクタの全体寸法も小さくすることができて、シールド付きコネクタの小型化が達成される。なお、前記プラグコネクタ側の切欠き部がある方向を横方向とすればそれに直交する縦方向においても、プラグコネクタ側の絶縁体が小型化されたことで、レセプタクルコネクタ側の絶縁体も小型化される。   According to the shielded connector of the present invention, the contact spring of the receptacle connector side shell is received by the notch portion of the insulator on the plug connector side, and the contact spring is bent outward by fitting with the shell on the plug connector side. The plate thickness and deflection are accommodated within the thickness range of the notch in the insulator on the plug connector side, so that no gap is required between the insulator and the shell, and the overall dimensions of the plug connector Can be made smaller than before. Therefore, the overall size of the receptacle connector fitted to this can be reduced, and the miniaturization of the shielded connector can be achieved. If the direction where the notch on the plug connector side is defined as the horizontal direction, the insulator on the plug connector side is also miniaturized in the vertical direction perpendicular thereto, so that the insulator on the receptacle connector side is also reduced in size. Is done.

本発明に係るシールド付きコネクタ１は、図１（Ａ）〜（Ｃ）と図２乃至図３に示すように、レセプタクルコネクタ２の接続部２ａにおける中心部に４個のコンタクト３と、該コンタクト３の周囲一部を囲撓する金属製シェル４ａと、接触バネ（グランドバネ）４ｂと、該シェル４ａ及び接触バネ４ｂの外側を囲撓する絶縁体５とが夫々配設されている。前記絶縁体５の外側には、更に、シェル６が被冠されており、前記シェル４及び接触バネ４ｂと電気的に導通されている。なお、図３に示す接続部４ｃは、絶縁体５にこのシェル４を挿着した時に、絶縁体５の外側に張り出して、前記シェル６と接触させて電気的に導通させるものである。   As shown in FIGS. 1A to 1C and FIGS. 2 to 3, the shielded connector 1 according to the present invention includes four contacts 3 at the center of the connection portion 2a of the receptacle connector 2, and the contacts. 3, a metal shell 4a that surrounds a part of the periphery of 3, a contact spring (ground spring) 4b, and an insulator 5 that surrounds the outside of the shell 4a and the contact spring 4b are disposed. A shell 6 is further covered on the outside of the insulator 5 and is electrically connected to the shell 4 and the contact spring 4b. In addition, when the shell 4 is inserted into the insulator 5, the connection portion 4 c shown in FIG. 3 protrudes to the outside of the insulator 5 and is brought into contact with the shell 6 for electrical conduction.

前記レセプタクルコネクタ２に嵌合するプラグコネクタ７においては、図４（Ａ）〜（Ｃ）に示すように、その接続部７ａにおける中心部に４個のコンタクト８と、前記レセプタクルコネクタ２側のシェル４ａの内側に嵌合する金属製シェル９と、該シェル９を囲撓すると共に前記レセプタクルコネクタ２側の絶縁体５の内側に嵌合する絶縁体１０とが夫々配設されている。   In the plug connector 7 to be fitted to the receptacle connector 2, as shown in FIGS. 4A to 4C, four contacts 8 and a shell on the receptacle connector 2 side are provided at the center of the connecting portion 7a. A metal shell 9 fitted inside 4a and an insulator 10 surrounding the shell 9 and fitted inside the insulator 5 on the receptacle connector 2 side are respectively provided.

前記プラグコネクタ７における、符号１１は嵌合時のロック用の爪を示し、符号１２は、ケーブルを示す。図５に示すように、このプラグコネクタ７側の筒状の絶縁体１０が、前記シェル９と組立用の所定の間隙ｃ１を有するとともに、前記レセプタクルコネクタ２側のシェル４における接触バネ４ｂ用の撓み分の間隙（図８において示すＣ２）を設けずに形成され、且つ、この絶縁体１０の板厚の寸法を前記レセプタクルコネクタ２側のシェル４の板厚分（図８おいて示すＤ）と、該シェル４ａにおける接触バネ４ｂの撓み分（図８において示すＣ２）との合計寸法以上とするものである。これにより、絶縁体１０の板厚分内で、接触バネ４ｂが撓むことになり、よって、この絶縁体１０の設計において、当該接触バネ４ｂの撓み分（Ｃ２）を含んで大きくする必要が無くなる。   In the plug connector 7, reference numeral 11 denotes a locking claw at the time of fitting, and reference numeral 12 denotes a cable. As shown in FIG. 5, the cylindrical insulator 10 on the plug connector 7 side has a predetermined gap c1 for assembly with the shell 9, and is used for the contact spring 4b in the shell 4 on the receptacle connector 2 side. The gap is formed without providing a gap (C2 shown in FIG. 8), and the thickness of the insulator 10 is set to the thickness of the shell 4 on the receptacle connector 2 side (D shown in FIG. 8). And the total dimension of the deflection of the contact spring 4b in the shell 4a (C2 shown in FIG. 8). As a result, the contact spring 4b bends within the thickness of the insulator 10. Therefore, in the design of the insulator 10, it is necessary to increase the contact spring 4b including the deflection (C2). Disappear.

また、前記プラグコネクタ７側の絶縁体１０の一部に、図４（Ｂ），（Ｃ）と図５とに示すように、前記レセプタクルコネクタ２側の接触バネ４ｂが嵌合時に入り込んで、プラグコネクタ７側のシェル９に接触するように当該シェル９を露出させる切欠き部１０ａを設ける。   Further, as shown in FIGS. 4 (B), 4 (C) and FIG. 5, a contact spring 4b on the receptacle connector 2 side enters into a part of the insulator 10 on the plug connector 7 side during fitting, A notch 10a for exposing the shell 9 is provided so as to contact the shell 9 on the plug connector 7 side.

前記切欠き部１０ａにおいて、レセプタクルコネクタ２とプラグコネクタ７とが嵌合され接続されると、レセプタクルコネクタ２側の接触バネ４ｂと、プラグコネクタ７側のシェル９とが直接接触して電気的に導通する。これにより、シェル４ａ、接触バネ４ｂ、シェル６、シェル９とによりシールド作用が発揮される。   When the receptacle connector 2 and the plug connector 7 are fitted and connected in the notch 10a, the contact spring 4b on the receptacle connector 2 side and the shell 9 on the plug connector 7 side are in direct contact with each other to be electrically connected. Conduct. Thereby, the shield action is exhibited by the shell 4a, the contact spring 4b, the shell 6 and the shell 9.

このように形成されるレセプタクルコネクタ２とプラグコネクタ７とを使用すると、図５に示すように、レセプタクルコネクタ２側のコンタクト３に、プラグコネクタ７側のコンタクト８とが嵌合する。そして、レセプタクルコネクタ２の接続部２ａにプラグコネクタ７のシェル９が挿入されると、切欠き部１０ａに入り込む接触バネ４ａにおける突起部４ｄが当接して、当該接触バネ４ｂが外側に撓む。   When the receptacle connector 2 and the plug connector 7 formed as described above are used, the contact 8 on the plug connector 7 side is fitted to the contact 3 on the receptacle connector 2 side as shown in FIG. When the shell 9 of the plug connector 7 is inserted into the connection portion 2a of the receptacle connector 2, the protruding portion 4d of the contact spring 4a entering the notch portion 10a comes into contact, and the contact spring 4b bends outward.

前記接触バネ４ｂが撓んでも、前記切欠き部１０ａにおける絶縁体１０の板厚分Ｅの範囲内に収められている。これにより、プラグコネクタ７の横方向（左右方向）における幅は、Ｓ＋２×（Ｃ１＋Ｂ＋Ｃ１＋Ｅ）となる。Ｃ１は、組立誤差用のクリアランスである。また、レセプタクルコネクタ２の横幅Ｗ１は、Ｗ１＝Ｓ＋２×（Ｇ＋Ｆ＋Ｅ＋Ｂ＋３Ｃ１）となる。   Even if the contact spring 4b is bent, the contact spring 4b is accommodated within the range of the thickness E of the insulator 10 in the notch 10a. Thereby, the width of the plug connector 7 in the lateral direction (left-right direction) is S + 2 × (C1 + B + C1 + E). C1 is a clearance for assembly error. The lateral width W1 of the receptacle connector 2 is W1 = S + 2 × (G + F + E + B + 3C1).

これを従来のシールド付きコネクタ１５におけるプラグコネクタ１７とレセプタクルコネクタ１６とで比較すると、プラグコネクタ１７ではＳ＋２×（Ｃ１＋Ｂ＋Ｃ１＋Ｄ＋Ｃ２＋Ｅ）となっており、本発明に係るプラグコネクタ７が２×（Ｄ＋Ｃ２）だけ小さい寸法となる。また、従来のレセプタクルコネクタ１６の横幅Ｗ２は、Ｗ２＝Ｓ＋２×（Ｇ＋Ｆ＋Ｅ＋Ｂ＋Ｃ２＋Ｄ＋３Ｃ１）となっており、これも本発明に係るレセプタクルコネクタ２が、２×（Ｄ＋Ｃ２）だけ小さい寸法となる。   When this is compared between the plug connector 17 and the receptacle connector 16 in the conventional shielded connector 15, the plug connector 17 is S + 2 × (C1 + B + C1 + D + C2 + E), and the plug connector 7 according to the present invention is smaller by 2 × (D + C2). It becomes a dimension. Further, the lateral width W2 of the conventional receptacle connector 16 is W2 = S + 2 × (G + F + E + B + C2 + D + 3C1), and the receptacle connector 2 according to the present invention also has a size that is smaller by 2 × (D + C2).

このようにして、シールド付きコネクタ１におけるプラグコネクタ７とレセプタクルコネクタ２との小型化が可能となったものである。プリント基板に実装した場合に、前記シールド付きコネクタ１の横幅が狭くなった事で、実装有効面積が拡張され、高密度実装に貢献するものである。   In this way, the plug connector 7 and the receptacle connector 2 in the shielded connector 1 can be reduced in size. When mounted on a printed circuit board, the effective width of the mounting is expanded because the width of the shielded connector 1 is reduced, contributing to high-density mounting.
