Description

【0001】
【発明の属する技術分野】
本発明は、コンタクトを保持する絶縁ハウジングの外周面に電気的ノイズを防止するシールド用の金属シェルを備えたシールド型コネクタに関する。
【0002】
【従来の技術】
電気コネクタの略箱形の絶縁ハウジングの外周面に電気的ノイズを防止する目的で金属製のシールド部材を配置することが知られている。この種のシールド型電気コネクタの一例が実開平5−34679号公報、特開平10−83866号公報等に開示されている。開示された電気コネクタは基板実装型のコネクタであり、金属板により構成される略コ字形状の一対のシールド部材が略箱形の絶縁ハウジングの外周の4面あるいは3面に重なるように配置される。
【0003】
図15及び図16に、こうした従来のシールド型電気コネクタの例を示す。なお、図15にリセプタクルコネクタRが示され、図16にプラグコネクタPが示されているが、プラグコネクタPに対してリセプタクルコネクタRが小さいために、図15を拡大して示している。
【0004】
この図15に示すリセプタクルコネクタRの場合、シールド部材は、一番外側に配置する平面略コ字形の金属シェル320と、その金属シェル320と内部の絶縁ハウジングとの間に配置された断面略コ字形状のシールド金属板330とにより構成されている。金属シェル320は、絶縁ハウジングの前面と両側面の3面を覆うように配置され、シールド金属板330は、絶縁ハウジングの上面と両側面の3面を覆うように配置される。これにより、絶縁ハウジングの前面、上面及び両側面の4面がシールドされる。シールド金属板320には、プラグコネクタ(相手方コネクタ)Pのシールド金属を兼ねた端子部310の表面の係合凹部311に係合する係合片303が設けられている。
【0005】
金属シェル320は、前面シールド部分323と両側の側面シールド部分324、324を有する。そして、前面シールド部分323には、プラグコネクタPの端子部310を挿入するための開口321を形成する嵌合筒部307が設けられている。この嵌合筒部307は図示のように略四角筒状に形成されていて、前面側に突出している。この金属シェル320は、金属板の打ち抜き加工後に、嵌合筒部307の部分を絞り加工により形成している。308は嵌合極性を与えるための凸部であり、312は凸部308と嵌合する凹部である。313はピンコンタクトを示す。
【0006】
【発明が解決しようとする課題】
近年の電気コネクタは小型化される傾向にあり、上述の基板実装型コネクタにおいても小型であることが要求される。加えて、製造コストが安く、寸法安定性も高いことが望まれる。また、小型化を図りつつ、シールド性能の向上及びその安定化を図ることも重要である。
【0007】
しかしながら、上述のようなコネクタにおいては、特に、嵌合筒部307を絞り加工により形成しているために、製造コストが高く、外形も大きくなって小型化を図り難いという問題がある。また、嵌合筒部307を絞り加工するため、その嵌合筒部307の寸法安定性が良くないという問題もある。さらに、このように絞り加工した嵌合筒部307の部分は、プラグコネクタPの嵌合時に「こじり」等による大きな力が作用すると、その力の程度によっては絞りが戻る、いわゆる開きが生じる恐れがないとは言えない。この点は、挿抜が頻繁に繰り返されるコネクタにおいては、十分に配慮する必要がある。
【0008】
また、この種のコネクタに関し、必要なシールド性能を維持しつつさらに小型化並びに軽量化を図るという観点から検討してみると、絶縁ハウジング自体にも改良の余地が残されていることが分かった。即ち、従来の絶縁ハウジングは6面を有する略箱形に構成されている。しかし、絶縁ハウジング本来の機能に着目した場合、複数のコンタクトを保持する機能の他に、絶縁ハウジングを覆うシールド部材と複数のコンタクトとを電気的に絶縁状態に保持する機能を発揮できれば良い。この点、従来の絶縁ハウジングは、強度的にも優れた金属シールド部材で覆う構造としているにもかかわらず、余分な肉厚や構造部分を有していたため、それ以上の小型化並びに軽量化を図り難いという問題があった。
【0009】
一方、挿抜が頻繁に繰り返されるコネクタにおいては、嵌合部分の摩耗や変形などによりプラグコネクタとリセプタクルコネクタとのシールド部材どうしの接触安定性(接触強さ)が次第に低下してがたつきが生じる場合がある。そのため、挿抜の頻度やその状態によってはノイズ成分を基板側のアースに導く接地安定性が損なわれたり、挿抜の安定性が損なわれたりする恐れがある。
【0010】
特に、接地安定性については、がたつきにより、プラグ側とリセプタクル側との電気的接続が不安定になり、伝幡してきたノイズ成分を基板側のアースに安定的に導くことが困難になってしまう懸念があった。
【0011】
本発明は、これらのような点に鑑みてなされたものであり、その目的は、シールド型コネクタの特にリセプタクル側において、小型化並びに軽量化を図ることができ、また、長期間の酷使に耐えてプラグ側との接続信頼性並びに挿抜の安定性を高めるとともに、プラグ側との接続時におけるノイズ成分の除去に極めて効果的なシールド型コネクタを提供することにある。
【0012】
【課題を解決するための手段】
前記課題を解決するため、本発明は以下の手段を採用した。
本発明の第1の手段は、コンタクトを保持した絶縁ハウジングと、その絶縁ハウジングの表面に重なるシールド部材とを備え、そのシールド部材は、相手方コネクタの端子部が嵌合する嵌合用開口の周囲を囲む枠部分を有する金属シェルと、その金属シェルと絶縁ハウジングとの間に配置される金属シールドとを含むシールド型コネクタであって、
前記絶縁ハウジングは、複数の開口を有する略箱形に形成されていて、その上面の一部を形成する上板部分と、底面の一部を形成する底板部分と、相手方コネクタの端子部の挿入口を有する前面部分と、コンタクトの引き出し口を有する背面部分とを有し、かつ、両側面部分が解放されていてその解放された両側面部分が前記シールド部材により覆われていることを特徴とする。
【0013】
この手段によれば、絶縁ハウジングの両側の側面部分を解放して両側の側板部分を無くす構成とすることで、その分、絶縁ハウジング自体を小さくかつ軽量化することができ、これによりコネクタ全体の小型化並びに軽量化を図ることができる。また、絶縁ハウジングの解放された両側面部分はシールド部材により覆われているので、コネクタ全体の強度及び必要なシールド性能も十分に確保されることになる。
【0014】
本発明の第2の手段は、第1の手段における金属シールドが、絶縁ハウジングの上面を覆う上面シールド部分と、絶縁ハウジングの解放された両側面部分を覆う側面シールド部分とを有し、それら側面シールド部分に、相手方コネクタの端子部の嵌合時にその端子部の相対する左右の側面に接触して端子部の嵌合状態を保持するバネ片がそれぞれ設けられていることを特徴とする。
【0015】
この第2の手段によれば、金属シールドの側面シールド部分にバネ片が設けられているが、絶縁ハウジングの両側面部分は解放されているので、両バネ片は相手方コネクタの端子部の側面にそれぞれ接触することができ、端子部をがたつきなく安定状態に保持する。これにより、相手方コネクタであるプラグ側と、リセプタクル側との電気的接続が安定になり、伝幡してきたノイズ成分を基板側のアースに安定的に導くことが可能になる。また、端子部の側面にバネ片が接触することで、プラグコネクタの挿抜時に端子部側面とバネ片との間に摩擦による抵抗と位置決め作用が生じる。この抵抗及び位置決め作用はバネ片により安定しているため、挿抜の安定性も向上する。
【0016】
本発明の第3の手段は、第1及び第2の手段における金属シールドの上面シールド部分に、相手方コネクタの端子部の嵌合時にその端子部表面の凹部に係合する係合片が設けられ、その係合片は、絶縁ハウジングの上板部分に形成された開口を通して絶縁ハウジング内に導かれていることを特徴とする。
【0017】
この第3の手段によれば、金属シールドの上面シールド部分に設けた係合片が端子部表面の凹部に係合して端子部を保持する。したがって、バネ片の位置決め作用の他にこの係合片による位置決め作用も端子部に加わるため、端子部はさらに安定状態に保持される。これによりプラグ側とリセプタクル側との電気的接続の安定性(接地安定性)及び挿抜の安定性をさらに良好にすることができる。絶縁ハウジングの上板部分には係合片を絶縁ハウジング内に導く開口が形成されているため、この開口も絶縁ハウジングの軽量化に寄与する。
【0018】
【発明の実施の形態】
以下、本発明の実施の形態を、添付の図1〜図14を参照して説明する。
これらの図に示す実施の形態は、本発明を、回路基板に挿入して実装するいわゆるディップタイプの電気コネクタに適用したものである。
【0019】
このシールド型コネクタRは、図1の斜視図、図2の正面図及び図3の断面図等に示すように、コンタクト1を保持した絶縁ハウジング10と、その絶縁ハウジング10の表面に重なるシールド用の金属シェル20とを備える。金属シェル20には、相手方コネクタ(図16参照)の端子部を嵌合するための嵌合用開口21とその嵌合用開口21の周囲を囲む枠部分22とが設けられている。
【0020】
枠部分22は、嵌合用開口21の周囲を一周する繋ぎ目のない連続した金属板の部分として形成されている。嵌合用開口21の中央下部には、枠部分22の一部から突出する凸部22aが形成されている。この凸部22aは、相手コネクタとの嵌合極性を付与する凸部である。なお、相手コネクタについては、図16と同様の既存のプラグコネクタが使用可能であるため、ここでは特別に図示していない。
【0021】
絶縁ハウジング10は、複数の開口を有する略箱形であって、全体が高強度の樹脂により形成されている。この絶縁ハウジング10について、具体的に説明する。絶縁ハウジング10は、図3、図4、図8、図9に示すように、その上面の一部を形成する上板部分10aと、底面の一部を形成する底板部分10bと、相手方コネクタの端子部の挿入口21を有する前面部分10cと、コンタクトの引き出し口11aを有する背面部分10dとを備えている。したがって、この絶縁ハウジング10は、図8及び図9から明らかなように両側面部分が解放されていて、側板部分が初めから設けられていない断面略コ字型(図4参照)の樹脂成形品として構成されている。
【0022】
絶縁ハウジング10の上板部分10aには、図3に示すように、後述する金属シールド30の係合片32を絶縁ハウジング10内に導くための開口10eが設けられている。また、この上板部分10aのうち、前面部分10c寄りの部分は金属シェル20の板厚の分だけ薄くした薄肉部10fに形成されている。これは金属シールド30の上に金属シェル30が部分的に重なるために、上板部分10aの板厚を調整することで、金属シェル20の表面と金属シールド30の表面とが面一になるように配慮したものである。
【0023】
絶縁ハウジング10には側板部分が設けられていないことから、図4に示すように、背面部分10dが、上板部分10a及び底板部分10bを片持ち状態で支持する構造となる。このため、背面部分10dについては絶縁ハウジング10全体の強度を高める目的で図示のように厚肉に形成している。
【0024】
絶縁ハウジング10の内部には、コンタクト保持部11と、相手方コネクタのピンコンタクトが挿入される挿入口12とを有する。コンタクト1の先端部2は、絶縁ハウジング10の先端保持部13に保持されている。コンタクト1の先端部2の近くには、挿入口12内へ突出するように湾曲した湾曲部3が形成され、挿入口12内へ挿入されるピンコンタクトとの接触強さが高まるように配慮されている。
【0025】
コンタクト1のタイン4は、絶縁ハウジング10の背面部分10dの引き出し口11aから引き出され、下方へ曲げられて真っ直ぐに延び、絶縁ハウジング10の下面よりも下方へ突出している。このタイン4の部分は基板のスルーホール等に挿入されて半田付けされる。図示例のコネクタRは4ピンコネクタであり、したがってコンタクト1も4つ配置されている。各コンタクト1のタイン4が集中するのを防ぐため各タイン4を千鳥配置としている。
【0026】
金属シェル20は、図10に示すように、導電性金属板を打ち抜き加工して展開形状の金属シェル20Aを形成した後に曲げ加工して形成したもので、▲1▼で示す前面シールド部分23と、▲2▼で示す両側の側面シールド部分24、24と、▲3▼で示す上面シールド部分25と、▲4▼で示す底面シールド部分26と、▲5▼で示す係合片27、27と、▲6▼で示す固定片28、28とを有し、これらの部分が絶縁ハウジング10の表面への重なり部分を構成している。▲1▼〜▲6▼で示す各重なり部分は図中破線で示す位置から曲げ加工される。これにより、金属シェル20は、絶縁ハウジング10の6面のそれぞれに少なくとも一部が重なる重なり部分を有する構成となる。
【0027】
このように、金属シェル20が絶縁ハウジング10の6面のそれぞれに少なくとも一部が重なる重なり部分を有することで、それら重なり部分の曲げ加工を施すだけで、金属シェル20を絶縁ハウジング10に対して容易にかつしっかりと固定することができる。
【0028】
また、金属シェル20の展開形状のもの20Aが破線部分から曲げ加工されて形成される繋ぎ目(図1参照)は、絶縁ハウジング10の両側面側に位置し、各繋ぎ目が面一となるように係合される係合片27、27を有することで、繋ぎ目が外側へ張り出さないようにしてその分、外形を小さく納めることができる。しかも、繋ぎ目が開かないようにするための係合片27と係合する切り欠き29、29は、双方の板厚の範囲内で係合片27と緊密に係合し合うように配慮している。図において、符号24aは図示しない回路基板等に形成されるスロットに差し込まれて半田付けされる突出片を示している。
【0029】
図1は金属シェル20の曲げ加工後の斜視図で、内部の絶縁ハウジング10を覆った状態の完成されたコネクタRを示しているが、このコネクタRには、さらに、金属板の加工(打ち抜きと曲げ加工)により形成した前記金属シールド30が設けられている。この金属シールド30は、絶縁ハウジング10と金属シェル20との間に配置され、金属シェル20により拘束された形態となっている。
【0030】
図11にその金属シールドの正面図を、図12にその断面図を、図13にその平面図を、図14にその右側面図をそれぞれ示している。
この金属シールド30は、正面から見て略コ字形に形成され、絶縁ハウジング10の上面の一部を覆う上面シールド部分31と、絶縁ハウジング10の解放された両側面を覆う側面シールド部分33、33と、それら側面シールド部分に形成されたバネ片34、34と、相手方コネクタの端子部に係合する係合片32とを有している。
【0031】
各バネ片34、34は、リセプタクルコネクタRに対する相手方コネクタの端子部の嵌合時にその端子部表面(相対する両側面)に接触して端子部の嵌合状態を保持する機能を有するように設定され、端子部をがたつきなく安定状態で保持する。即ち、各バネ片34、34は、側面シールド部分33、33に連続した基端部34a、34aと、その基端部から延びる自由端部34b、34bとを有する板状であり、その自由端部34b、34bが側面シールド部分に沿って絶縁ハウジングの背面側へ延びている。
【0032】
両側面シールド部分33、33に、それぞれ板状の各バネ片34、34を形成するために、両側面シールド部分33、33に側面からみて略コ字形の切り抜き35、35を形成している。各バネ片34、34は基端部34a、34a付近に曲げを入れることで、ほぼ肉厚程度の範囲で内側に突出している。これにより、各バネ片34、34は、端子部が挿入される嵌合用開口21の左右の内壁面側にそれぞれ配置され、各バネ片34、34が端子部の相対する左右の側面にそれぞれ接触するように配慮されている。
【0033】
係合片32は屈曲部32aを介して後方へ曲げられてその自由端部32bが絶縁ハウジング10内に位置している。そして、その自由端部32bの近くに、端子部表面の凹部に係合する係合凸部32cが設けられている。
【0034】
本実施の形態では、絶縁ハウジング10の両側の側面部分を解放して両側の側板部分を無くす構成とすることで、その分、絶縁ハウジング10自体を小さくかつ軽量化することができ、これによりコネクタ全体の小型化並びに軽量化を図ることができる。また、絶縁ハウジング10の解放された両側面部分は金属シェル20及び金属シールド30の側面シールド部分24及び33により覆われているので、コネクタ全体の強度及び必要なシールド性能も十分に確保されることになる。
【0035】
また、金属シールド30の側面シールド部分33、33にバネ片34、34が設けられているが、絶縁ハウジング10の両側面部分は解放されているので、両バネ片34、34はプラグコネクタ(P)の端子部(310)の側面にそれぞれ接触することができ、端子部をがたつきなく安定状態に保持する。これにより、相手方コネクタであるプラグコネクタ(P)と、リセプタクルコネクタRとの電気的接続が安定になり、伝幡してきたノイズ成分を基板側のアースに安定的に導くことが可能になる。また、端子部表面にバネ片34、34が接触することで、プラグコネクタの挿抜時に端子部表面とバネ片34、34との間に摩擦による抵抗と位置決め作用が生じる。この抵抗及び位置決め作用はバネ片の存在により安定しているため、挿抜の安定性も向上する。
【0036】
また、左右に配置したバネ片34、34が端子部の相対する左右の側面に接触するように設定することで、端子部を両側から挟み込むように保持することができる。これにより、プラグ側とリセプタクル側との電気的接続の安定性(接地安定性)及び挿抜の安定性がさらに良好になる。
【0037】
また、各バネ片34は板状でその自由端部34bが側面シールド部分33に沿って絶縁ハウジング10の背面側へ延びている。このため、各バネ片34、34の一部を図示のように互いに接近する方向に曲げるだけの簡単な加工で端子部表面に接触可能にすることができる。その場合、各バネ片34、34は板状であるので、端子部表面に均一に面接触させるようにすることもできる。また、各バネ片34、34の自由端部34bは、端子部の挿抜方向へ沿って延びているので、その自由端部34b、34bの存在が端子部の挿抜に支障を招くこともない。
【0038】
なお、以上の実施の形態によれば、相手方コネクタの端子部が嵌合する嵌合用開口21及び枠部分22を含む展開形状の金属シェルを金属板材の打ち抜き加工により形成することで、嵌合用開口21の寸法安定性を図り、高精度な嵌合用開口21とすることができる。また、絞り加工に代えて打ち抜き加工ですむため、製作容易で低コスト化及び小型化を図ることが可能になる。さらに、嵌合用開口21を囲む枠部分22は絞りや繋ぎ目のない連続した金属板の部分で形成されるため、強度的にも優れた形状となる。
【0039】
【発明の効果】
以上のように、本発明によれば、シールド型コネクタの特にリセプタクル側において、小型化並びに軽量化を図ることができ、また、長期間の酷使に耐えてプラグ側との接続信頼性並びに挿抜の安定性を高めるとともに、プラグ側との接続時におけるノイズ成分の除去に極めて効果的なシールド型コネクタを提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a shielded connector including a shield metal shell for preventing electrical noise on an outer peripheral surface of an insulating housing that holds a contact.
[0002]
[Prior art]
It is known that a metal shield member is disposed on the outer peripheral surface of a substantially box-shaped insulating housing of an electrical connector for the purpose of preventing electrical noise. Examples of this type of shielded electrical connector are disclosed in Japanese Utility Model Laid-Open No. 5-34679, Japanese Patent Laid-Open No. 10-83866, and the like. The disclosed electrical connector is a board-mounted connector, and a pair of substantially U-shaped shield members made of a metal plate are arranged so as to overlap four or three surfaces of a substantially box-shaped insulating housing. The
[0003]
15 and 16 show examples of such conventional shielded electrical connectors. 15 shows the receptacle connector R, and FIG. 16 shows the plug connector P. Since the receptacle connector R is smaller than the plug connector P, FIG. 15 is shown enlarged.
[0004]
In the case of the receptacle connector R shown in FIG. 15, the shield member includes a planar substantially U-shaped metal shell 320 disposed on the outermost side, and a substantially cross-sectional shape of the cross-section disposed between the metal shell 320 and the internal insulating housing. The shield metal plate 330 is shaped like a letter. The metal shell 320 is disposed so as to cover the three surfaces of the front surface and both side surfaces of the insulating housing, and the shield metal plate 330 is disposed so as to cover the three surfaces of the upper surface and both side surfaces of the insulating housing. Thereby, the four surfaces of the front surface, the upper surface, and both side surfaces of the insulating housing are shielded. The shield metal plate 320 is provided with an engagement piece 303 that engages with an engagement recess 311 on the surface of the terminal portion 310 that also serves as a shield metal of the plug connector (mating connector) P.
[0005]
The metal shell 320 has a front shield part 323 and side shield parts 324 and 324 on both sides. The front shield portion 323 is provided with a fitting cylinder portion 307 that forms an opening 321 for inserting the terminal portion 310 of the plug connector P. The fitting cylinder portion 307 is formed in a substantially square cylinder shape as shown in the figure, and protrudes to the front side. In the metal shell 320, after the metal plate is punched, a portion of the fitting cylinder portion 307 is formed by drawing. Reference numeral 308 denotes a convex portion for giving a fitting polarity, and reference numeral 312 denotes a concave portion that fits the convex portion 308. Reference numeral 313 denotes a pin contact.
[0006]
[Problems to be solved by the invention]
In recent years, electrical connectors tend to be miniaturized, and the above-described board-mounted connectors are also required to be small. In addition, it is desired that the manufacturing cost is low and the dimensional stability is high. It is also important to improve and stabilize the shielding performance while reducing the size.
[0007]
However, in the connector as described above, since the fitting tube portion 307 is formed by drawing, there is a problem that the manufacturing cost is high, the outer shape is large, and it is difficult to reduce the size. Moreover, since the fitting cylinder part 307 is drawn, there is a problem that the dimensional stability of the fitting cylinder part 307 is not good. Furthermore, when a large force due to “squeezing” or the like is applied to the portion of the fitting cylinder portion 307 that has been drawn in this manner when the plug connector P is fitted, the so-called opening may occur, depending on the degree of the force. It cannot be said that there is no. This point needs to be sufficiently considered in a connector in which insertion and extraction are frequently repeated.
[0008]
In addition, when examining this type of connector from the viewpoint of further reducing the size and weight while maintaining the necessary shielding performance, it was found that there is still room for improvement in the insulating housing itself. . That is, the conventional insulating housing is formed in a substantially box shape having six surfaces. However, when paying attention to the original function of the insulating housing, it is only necessary to exhibit the function of electrically maintaining the shield member and the plurality of contacts covering the insulating housing in addition to the function of holding the plurality of contacts. In this regard, the conventional insulating housing has a structure that is covered with a metal shield member that is excellent in strength, but has an extra thickness and a structural portion. Therefore, further reduction in size and weight can be achieved. There was a problem that it was difficult to plan.
[0009]
On the other hand, in connectors where insertion and removal are frequently repeated, the contact stability (contact strength) between the shield members of the plug connector and the receptacle connector gradually decreases due to wear or deformation of the fitting portion, resulting in rattling. There is a case. Therefore, depending on the frequency of insertion / extraction and the state thereof, there is a risk that the grounding stability for guiding the noise component to the ground on the substrate side may be impaired, or the stability of insertion / extraction may be impaired.
[0010]
In particular, regarding grounding stability, the electrical connection between the plug side and the receptacle side becomes unstable due to rattling, making it difficult to stably guide the transmitted noise component to the ground on the board side. There was a concern.
[0011]
The present invention has been made in view of the above points, and an object of the present invention is to reduce the size and weight of the shield-type connector, particularly on the receptacle side, and to withstand long-term abuse. It is an object of the present invention to provide a shielded connector that is highly effective in removing noise components when connected to the plug side, while improving the connection reliability with the plug side and the stability of insertion / extraction.
[0012]
[Means for Solving the Problems]
In order to solve the above problems, the present invention employs the following means.
According to a first aspect of the present invention, an insulating housing holding a contact and a shield member overlapping the surface of the insulating housing are provided, and the shield member surrounds a fitting opening into which a terminal portion of the mating connector is fitted. A shielded connector including a metal shell having a surrounding frame portion, and a metal shield disposed between the metal shell and the insulating housing,
The insulating housing is formed in a substantially box shape having a plurality of openings, and an upper plate portion that forms a part of the upper surface, a bottom plate portion that forms a part of the bottom surface, and insertion of a terminal portion of the mating connector A front portion having a mouth, and a rear portion having a contact outlet, and both side portions are open and the open side portions are covered with the shield member. To do.
[0013]
According to this means, the side portions on both sides of the insulating housing are released and the side plate portions on both sides are eliminated, so that the insulating housing itself can be made smaller and lighter, and thus the entire connector can be reduced. A reduction in size and weight can be achieved. Further, since the both side surfaces of the insulating housing that are released are covered with the shield member, the strength of the entire connector and the necessary shielding performance are sufficiently ensured.
[0014]
According to a second means of the present invention, the metal shield in the first means has a top shield part that covers the top surface of the insulating housing and side shield parts that cover the released side surface parts of the insulating housing. Each of the shield portions is provided with a spring piece that contacts the left and right side surfaces facing each other when the terminal portion of the mating connector is fitted to hold the fitting state of the terminal portion.
[0015]
According to this second means, the spring pieces are provided on the side shield part of the metal shield, but since both side parts of the insulating housing are released, both spring pieces are placed on the side face of the terminal part of the mating connector. Each can be contacted, and the terminal portion is held in a stable state without rattling. Thereby, the electrical connection between the plug side which is the counterpart connector and the receptacle side becomes stable, and the transmitted noise component can be stably guided to the ground on the board side. Further, when the spring piece comes into contact with the side surface of the terminal portion, frictional resistance and positioning action occur between the terminal side surface and the spring piece when the plug connector is inserted and removed. Since this resistance and positioning action are stabilized by the spring piece, the stability of insertion / extraction is also improved.
[0016]
According to a third means of the present invention, an engagement piece is provided on the upper surface shield portion of the metal shield in the first and second means to engage with the concave portion of the terminal portion surface when the terminal portion of the mating connector is fitted. The engaging piece is guided into the insulating housing through an opening formed in the upper plate portion of the insulating housing.
[0017]
According to the third means, the engagement piece provided on the upper shield portion of the metal shield engages with the recess on the surface of the terminal portion to hold the terminal portion. Therefore, in addition to the positioning action of the spring piece, the positioning action by the engaging piece is also applied to the terminal part, so that the terminal part is held in a more stable state. Thereby, the electrical connection stability (grounding stability) between the plug side and the receptacle side and the stability of insertion / extraction can be further improved. Since an opening for guiding the engaging piece into the insulating housing is formed in the upper plate portion of the insulating housing, this opening also contributes to the weight reduction of the insulating housing.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to FIGS.
In the embodiments shown in these drawings, the present invention is applied to a so-called dip type electrical connector that is mounted by being inserted into a circuit board.
[0019]
As shown in the perspective view of FIG. 1, the front view of FIG. 2, the cross-sectional view of FIG. 3, etc., this shield-type connector R has a shield housing that overlaps the surface of the insulation housing 10 that holds the contacts 1. Metal shell 20. The metal shell 20 is provided with a fitting opening 21 for fitting a terminal portion of a mating connector (see FIG. 16) and a frame portion 22 surrounding the fitting opening 21.
[0020]
The frame portion 22 is formed as a continuous metal plate portion that makes a round around the fitting opening 21. A convex portion 22 a that protrudes from a part of the frame portion 22 is formed at the center lower portion of the fitting opening 21. This convex part 22a is a convex part which provides fitting polarity with the other party connector. The mating connector is not specifically shown here because an existing plug connector similar to that of FIG. 16 can be used.
[0021]
The insulating housing 10 has a substantially box shape having a plurality of openings, and is entirely formed of high-strength resin. The insulating housing 10 will be specifically described. As shown in FIGS. 3, 4, 8, and 9, the insulating housing 10 includes an upper plate portion 10 a that forms part of the top surface, a bottom plate portion 10 b that forms part of the bottom surface, and a mating connector. A front portion 10c having a terminal insertion port 21 and a back portion 10d having a contact outlet 11a are provided. Therefore, as is apparent from FIGS. 8 and 9, the insulating housing 10 is a resin molded product having a substantially U-shaped cross section (see FIG. 4) in which both side surface portions are open and side plate portions are not provided from the beginning. It is configured as.
[0022]
As shown in FIG. 3, the upper portion 10 a of the insulating housing 10 is provided with an opening 10 e for guiding an engagement piece 32 of a metal shield 30 described later into the insulating housing 10. Further, of the upper plate portion 10 a, the portion near the front surface portion 10 c is formed in a thin portion 10 f that is thinned by the plate thickness of the metal shell 20. This is because the metal shell 30 partially overlaps the metal shield 30, so that the surface of the metal shell 20 and the surface of the metal shield 30 are flush with each other by adjusting the thickness of the upper plate portion 10a. It is something that takes into account.
[0023]
Since the insulating housing 10 is not provided with a side plate portion, as shown in FIG. 4, the back surface portion 10d has a structure that supports the upper plate portion 10a and the bottom plate portion 10b in a cantilever state. For this reason, the back surface portion 10d is formed thick as shown in order to increase the strength of the insulating housing 10 as a whole.
[0024]
The insulating housing 10 has a contact holding portion 11 and an insertion port 12 into which a pin contact of the mating connector is inserted. The tip 2 of the contact 1 is held by the tip holding part 13 of the insulating housing 10. A curved portion 3 that is curved so as to protrude into the insertion port 12 is formed near the distal end portion 2 of the contact 1, and consideration is given to increase the contact strength with the pin contact that is inserted into the insertion port 12. ing.
[0025]
The tine 4 of the contact 1 is drawn out from the lead-out port 11 a of the back surface portion 10 d of the insulating housing 10, is bent downward and extends straight, and protrudes downward from the lower surface of the insulating housing 10. This tine 4 portion is inserted into a through hole or the like of the substrate and soldered. The connector R in the illustrated example is a 4-pin connector, and therefore four contacts 1 are also arranged. In order to prevent the tines 4 of the contacts 1 from concentrating, the tines 4 are arranged in a staggered manner.
[0026]
As shown in FIG. 10, the metal shell 20 is formed by punching a conductive metal plate to form an unfolded metal shell 20A and then bending it. , (2) side shield portions 24, 24 on both sides, (3) top shield portion 25, (4) bottom shield portion 26, (5) engagement pieces 27, 27 , {Circle over (6)}, and these portions constitute overlapping portions on the surface of the insulating housing 10. Each overlapping portion indicated by (1) to (6) is bent from the position indicated by the broken line in the figure. As a result, the metal shell 20 has an overlapping portion that at least partially overlaps each of the six surfaces of the insulating housing 10.
[0027]
As described above, since the metal shell 20 has overlapping portions at least partially overlapping each of the six surfaces of the insulating housing 10, the metal shell 20 can be attached to the insulating housing 10 only by bending the overlapping portions. Can be fixed easily and firmly.
[0028]
Further, joints (see FIG. 1) formed by bending the metal shell 20 having a developed shape 20A from the broken line portion are located on both side surfaces of the insulating housing 10, and the joints are flush with each other. By having the engagement pieces 27 and 27 engaged in this manner, the outer shape can be reduced by a small amount so that the joint does not protrude outward. In addition, the notches 29 and 29 that engage with the engagement piece 27 for preventing the joint from being opened are considered to be closely engaged with the engagement piece 27 within the range of both plate thicknesses. ing. In the figure, reference numeral 24a denotes a protruding piece that is inserted into a slot formed in a circuit board (not shown) and soldered.
[0029]
FIG. 1 is a perspective view of the metal shell 20 after bending, and shows the completed connector R in a state of covering the inner insulating housing 10. The connector R further includes processing (punching) of a metal plate. And the metal shield 30 formed by bending). The metal shield 30 is disposed between the insulating housing 10 and the metal shell 20 and is constrained by the metal shell 20.
[0030]
FIG. 11 is a front view of the metal shield, FIG. 12 is a sectional view thereof, FIG. 13 is a plan view thereof, and FIG. 14 is a right side view thereof.
The metal shield 30 is formed in a substantially U-shape when viewed from the front, and includes a top shield portion 31 that covers a part of the top surface of the insulating housing 10 and side shield portions 33 and 33 that cover both released side surfaces of the insulating housing 10. And spring pieces 34 and 34 formed on the side shield portions, and an engagement piece 32 that engages with a terminal portion of the mating connector.
[0031]
Each spring piece 34, 34 is set so as to have a function of contacting the terminal part surface (opposite side faces) and maintaining the fitting state of the terminal part when the terminal part of the mating connector is fitted to the receptacle connector R. The terminal portion is held in a stable state without rattling. That is, each spring piece 34, 34 is plate-shaped having base end portions 34a, 34a continuous to the side shield portions 33, 33 and free end portions 34b, 34b extending from the base end portions. The portions 34b, 34b extend to the back side of the insulating housing along the side shield portions.
[0032]
In order to form the plate-like spring pieces 34, 34 on the side shield portions 33, 33, respectively, substantially U-shaped cutouts 35, 35 are formed on the side shield portions 33, 33 as viewed from the side. Each spring piece 34, 34 protrudes inward in the range of about the wall thickness by bending the proximal end portions 34a, 34a. Thereby, each spring piece 34 and 34 is each arrange | positioned at the left-and-right inner wall surface side of the fitting opening 21 in which a terminal part is inserted, and each spring piece 34 and 34 contacts the left and right side surfaces which a terminal part opposes, respectively. Considered to be.
[0033]
The engaging piece 32 is bent rearward through the bent portion 32 a and the free end portion 32 b is located in the insulating housing 10. And the engagement convex part 32c engaged with the recessed part of the terminal part surface is provided near the free end part 32b.
[0034]
In the present embodiment, the side portions on both sides of the insulating housing 10 are released to eliminate the side plate portions on both sides, so that the insulating housing 10 itself can be made smaller and lighter, and thus the connector. The overall size and weight can be reduced. In addition, since the released both side portions of the insulating housing 10 are covered with the side shield portions 24 and 33 of the metal shell 20 and the metal shield 30, the strength of the entire connector and the necessary shield performance can be sufficiently secured. become.
[0035]
Further, although the spring pieces 34 and 34 are provided on the side shield portions 33 and 33 of the metal shield 30, both the side pieces of the insulating housing 10 are released, so that both the spring pieces 34 and 34 are plug connectors (P ) Can be in contact with the side surfaces of the terminal portion (310), and the terminal portion can be held in a stable state without rattling. Thereby, the electrical connection between the plug connector (P), which is the counterpart connector, and the receptacle connector R becomes stable, and the transmitted noise component can be stably guided to the ground on the board side. Further, when the spring pieces 34 and 34 come into contact with the surface of the terminal portion, frictional resistance and positioning action are generated between the terminal portion surface and the spring pieces 34 and 34 when the plug connector is inserted and removed. Since the resistance and the positioning action are stable due to the presence of the spring piece, the insertion / extraction stability is also improved.
[0036]
In addition, by setting the spring pieces 34, 34 arranged on the left and right so as to contact the left and right side surfaces facing each other, the terminal portion can be held so as to be sandwiched from both sides. As a result, the electrical connection stability (grounding stability) between the plug side and the receptacle side and the stability of insertion / extraction are further improved.
[0037]
Each spring piece 34 has a plate shape, and its free end 34 b extends along the side shield part 33 toward the back side of the insulating housing 10. For this reason, it is possible to make contact with the surface of the terminal portion by a simple process of bending a part of each of the spring pieces 34, 34 in a direction approaching each other as shown. In that case, since each spring piece 34 and 34 is plate-shaped, it can also be made to make a surface contact uniformly to the terminal part surface. In addition, since the free ends 34b of the spring pieces 34, 34 extend in the insertion / extraction direction of the terminal portion, the presence of the free ends 34b, 34b does not hinder the insertion / extraction of the terminal portion.
[0038]
In addition, according to the above embodiment, the opening for fitting is formed by punching the metal plate material by forming the unfolded metal shell including the fitting opening 21 and the frame portion 22 into which the terminal portion of the mating connector is fitted. Thus, the dimensional stability of 21 can be achieved, and a highly accurate fitting opening 21 can be obtained. In addition, since punching is required instead of drawing, it is easy to manufacture and can be reduced in cost and size. Furthermore, since the frame portion 22 surrounding the fitting opening 21 is formed by a continuous metal plate portion without a diaphragm or a joint, the shape is excellent in strength.
[0039]
【The invention's effect】
As described above, according to the present invention, it is possible to reduce the size and weight of the shield-type connector, particularly on the receptacle side, and to withstand long-term abuse and to improve the connection reliability and insertion / removal of the plug side. It is possible to provide a shielded connector that is highly effective in improving stability and removing noise components when connected to the plug side.
