Description

【0001】
【発明の属する技術分野】
本発明は基板端部に接続されるコネクタに係り、特に、プラズマディスプレイパネルの端部に接続されるコネクタに関する。
【0002】
図1(A)に示すように、プラズマディスプレイパネル(以下、PDPという)10は、上面に処理が施された下側のガラス基板11と下面に処理が施された上側のガラス基板12とが積層された構造である。16が表示面である。下側のガラス基板11の端部11aは、上側のガラス基板12の周縁より外側に張り出しており、この部分にパッド列13が形成されている。パッド列13は、パッド14,15が例えば0.25mmのピッチで千鳥状に並んでいる構成である。
【0003】
PDP10の縁には、プラズマディスプレイパネル用コネクタが下側のガラス基板11の端部11aを挟み込んで接続されている。
【0004】
【従来の技術】
従来のプラズマディスプレイパネル用コネクタ(以下、PDP用コネクタという)20は、図1(B)に示すように、ガラス基板11の端部11aを挟み込む凹部21の箇所に、ばね性の腕部22を有する構成である。凹部21の寸法Aは、ガラス基板11の厚さtより少し小さい。
【0005】
PDP用コネクタ20は、腕部22を拡げるように弾性変形させつつ、ガラス基板11の端部11aに押し込んで、端部11aに嵌合させて接続されている。
【0006】
【発明が解決しようとする課題】
このため、PDP用コネクタ20をガラス基板11の端部11aに突き当てた状態でパッドに対して位置を合わせたとしても、PDP用コネクタ20を差し込む過程で位置ずれが発生し、接続した状態で、端子部材23のコンタクト部23aの位置がパッド15に対してずれる場合が起き易かった。この位置ずれが発生して電気的接続が正常でない場合には、位置ずれを修正することが必要となるけれども、修正作業は難しく、コネクタ20を引き抜いて外し、再度、接続することが必要となり、作業が面倒であった。
【0007】
また、コネクタ20を接続する過程及びコネクタ20を引き抜く過程で、ばね性の腕部22がガラス基板11及びパッド15を擦することになり、ガラス基板11及びパッド15を傷める虞れもあった。
【0008】
そこで、本発明は、上記課題を解決した基板端部に接続されるコネクタを提供することを目的とする。
【0009】
【課題を解決するための手段】
請求項1の発明は、パッドを有する基板の端部に、該基板の端部を挟んで接続されるコネクタにおいて、
底側に脚部を有する略枠状のシェル部材と、
夫々がコンタクト部を有する複数の端子部材がそのコンタクト部が突き出た状態で並んで固定してある端子部材保持体とを有し、
該端子部材保持体が該シェル部材の内部に組み込まれており、該シェル部材の脚部と上記端子部材のコンタクト部との間に、上記基板の端部を緩く受け入れる凹部が形成してあり、
上記凹部に嵌合した基板の端部を上記端子部材のコンタクト部に押し付ける押し付け機構を有し、
上記端子部材のコンタクト部が弾性変形し、上記凹部に嵌合した基板の端部が弾性変形したコンタクト部と上記押し付け機構との間に挟まれ、且つ、該コンタクト部と上記パッドとが弾性的に接触する構成とし、
上記シェル部材は、脚部をコネクタの長手方向の両端側に有する形状であり、
上記押し付け機構はブリッジ部材であって、当該ブリッジ部材は、前記両側側の脚部よりも前記コンタクト部が突き出た方向側にオフセットされて位置し前記脚部の間を跨る山形部と、両側の脚部に下方からねじ止めされて取り付けられるねじ止め部とを有し、前記山部は上記基板の端部を上記端子部材のコンタクト部に押し付けることを特徴とする。
【0010】
基板の端部に緩く嵌合して、押し付け機構によって寄せられるため、基板の端部及びパッドが擦られることが起きず、基板の端部及びパッドを傷めることを防止出来る。コンタクト部とパッドとの位置合わせは、押し付け機構を最終的な状態とする前になされるため、コンタクト部とパッドとの位置合わせを容易に行うことが出来る。よって、接続の信頼性を向上させることが出来る。
【0015】
ブリッジ部材の山形部が基板の端部に当る面積は広くなり、基板の端部に傷みは発生しにくい。
【0016】
請求項2の発明は請求項1記載のコネクタにおいて、
上記シェル部材は、その天板部に、上記端子部材のコンタクト部を見ることが可能である切欠部を有する構成としたものである。
【0017】
切欠部を通して見て、コンタクト部とパッドとの位置関係を確認することが可能となり、押し付け機構を最終的に動かす前に、コンタクト部とパッドとが一致するように位置関係を調整することが容易となる。
【0018】
【発明の実施の形態】
各図において、X1−X2は、PDP10の横方向及びPDP用コネクタ30の端子部材の並び方向である。Y1−Y2は、PDP10の縦方向及びPDP用コネクタ30の端子部材の長手方向である。Y1側がコンタクト部が突き出している側である。Z1−Z2は、PDP10の厚さ方向及びPDP用コネクタ30の厚さ方向である。
【0019】
[第1実施例]
図2乃至図6は、本発明の第1実施例になるPDP用コネクタ30を示す。PDP用コネクタ30は、特に図6に示すように、第1の端子部材保持体40と、第2の端子部材保持体50と、シェル部材60と、2つの楔部材70、71とを有する。
【0020】
第1の端子部材保持体40は、第1の端子部材41が0.5mmの等間隔で並んだ状態でインサート成形されている略直方体形状の細長い電気絶縁性の部材であり、X1−X2の両端にフランジ部42,43を有する。第1の端子部材41は、Y1方向に突き出ている第1のコンタクト部41aを有し、Y2方向に突き出ている端子部41bを有する。
【0021】

【0022】
シェル部材60は、金属製でありプレス加工されて製造された略長方形の枠形状であり、天板部61と、両側の側板部62,63と、側板部62,63の下端から内側に折り曲げられて底側の両側に形成されている脚部64,65とを有する。側板部62,63のうち脚部64,65の側には、ガラス基板11の端部11aが嵌合する切欠部66,67が形成してある。脚部64,65のY1側は、傾斜面64a,65aとなっている。天板部61には、後述する接続時に、第1、第2のコンタクト部41a、51aが夫々PDP10上のパッド14,15上に位置していることを目視によって確認するために利用される切欠部61a,61bが形成してある。
【0023】
第1の端子部材保持体40と第2の端子部材保持体50とは、凸部44を凹部53に嵌合されて位置決めされて重なっており、この状態で、シェル部材60の内部に圧入されて組み込まれている。
【0024】
第1のコンタクト部41aは切欠部52bに嵌合して位置を決められ、且つX1−X2への動きを規制されている。また、第1のコンタクト部41aはY1側、第2のコンタクト部51aはY2側に位置している。よって、第1のコンタクト部41aと第2のコンタクト部51aとは、PDP10上のパッド14,15の並びに対応した並びで千鳥状に並んでおり、位置を決められており、且つ、X1−X2への動きを制限されている。
【0025】
脚部64,65と第1、第2のコンタクト部41a、51aとの間には、ガラス基板11の端部11aを緩く受け入れる凹部80が形成される。この凹部80のZ1−Z2方向の寸法Bは、ガラス基板11の端部11aの厚さtより大きい。
【0026】
第2の端子部材保持体50には、脚部64,65に対向する部分に、Y1−Y2方向に延在する溝部54、55が形成してある。第2の端子部材保持体50の溝部54、55と脚部64,65とが、楔部材70、71が差し込まれるトンネル56,57を形成している。溝部54、55は、楔部材70、71の最終挿入位置を決めるストッパ部54a、55aを有する。
【0027】
楔部材70、71は、略T字形状であり、先端に傾斜面部70a、71aを有し、基部に腕部70b、71bを有する。楔部材70、71が押し付け機構を構成する。
【0028】
上記のPDP用コネクタ30は、図7及び図8に示すように、端子部41b、51bを折り曲げ、この折り曲げた端子部41b、51bを半田付けされて、小さいサイズの回路基板90に実装してある。回路基板90には、上記のトンネル56,57に対応する部位に、開口91,92が形成してある。
【0029】
次に、上記構成のPDP用コネクタ30をPDP10に接続する作業等について説明する。
【0030】
PDP用コネクタ30のPDP10への接続は、以下の手順で行う。
【0031】
▲1▼ 図7(A)に示すように、PDP用コネクタ30の凹部80をPDP10のガラス基板11の端部11aとゆるく嵌合させる。凹部80の奥側の第2の端子部材保持体50の面50aが端部11aの端面11bと突き当たる状態とする。
【0032】
▲2▼ PDP用コネクタ30をPDP10に対してZ2方向にシフトさせ、楔部材70、71を開口91,92を通して、トンネル56,57内に軽く突き刺し、傾斜面部70a、71aがガラス基板11の端部11aを支える状態とする。
【0033】
▲3▼ 切欠部61a,61bから覗いて、第1、第2のコンタクト部41a、51aのパッド14,15に対する位置を確認し、必要に応じてPDP用コネクタ30をX1−X2方向に適宜僅かに動かして、第1、第2のコンタクト部41a、51aを夫々パッド14,15上に位置させる。
【0034】
▲4▼ この状態で、治具を使用して、楔部材70、71を最終位置まで押し込む。最終位置は、腕部70b、71bがストッパ部54a、55aに当った位置である。
【0035】
以上によって、図7(B)に示す状態となって、PDP用コネクタ30のPDP10への接続が完了する。ガラス基板11の端部11aが楔部材70、71によってZ1方向に押し上げられて第1、第2のコンタクト部41a、51a側に寄せられ、第1、第2のコンタクト部41a、51aがZ1方向に弾性変形され、第1、第2のコンタクト部41a、51a自身の弾性力Fによって、第1、第2のコンタクト部41a、51aと楔部材70、71との間にガラス基板11の端部11aを挟むことによって、PDP用コネクタ30はPDP10に機械的に接続される。また、第1、第2のコンタクト部41a、51aが夫々パッド14,15に弾性的に接触されて、PDP用コネクタ30がPDP10と電気的に接続される。
【0036】
PDP用コネクタ30は、図8に示すように、PDP10の縁に沿って並んだ状態となる。
【0037】
ここで、楔部材70、71はPDP10の外側の位置から挿入されるため、PDP10の裏面から挿入する場合に比べて、PDP10を擦るようなことが起きず、しかも、邪魔するものがなく、挿入する作業はし易い。
【0038】
[第2実施例]
図9に示すように、本発明の第2実施例になるPDP用コネクタ30Aは、上記の第1実施例になるPDP用コネクタ30における楔部材70、71に代えて、押しねじ100,101を使用した構成である。
【0039】
シェル部材60Aは、脚部64,65にねじ孔64a,65aが形成してある構成である。第1の端子部材保持体40と第2の端子部材保持体50とは重なった状態で、シェル部材60Aの内部に圧入されて組み込まれている。押しねじ100,101はZ2側からねじ孔64a,65aに螺合してある。押しねじ100,101が押し付け機構を構成する。
【0040】
PDP用コネクタ30AのPDP10への接続は、以下の手順で行う。
【0041】
図10(A)に示すように、PDP用コネクタ30の凹部80をPDP10のガラス基板11の端部11aと突き当たるまで、ゆるく嵌合させる。次いで、押しねじ100,101を締めて、押しねじ100,101を凹部80内に突き出させ、PDP用コネクタ30を押してPDP10に対してZ2方向に変位させ、第1、第2のコンタクト部41a、51aがパッド14,15と軽く接触する状態とする。この状態で、切欠部61a,61bから覗いて、第1、第2のコンタクト部41a、51aのパッド14,15に対する位置を確認し、必要に応じてPDP用コネクタ30をX1−X2方向に適宜僅かに動かして、第1、第2のコンタクト部41a、51aを夫々パッド14,15上に位置させる。第1、第2のコンタクト部41a、51aが夫々パッド14,15上に位置することを確認して、この状態で、押しねじ100,101をきつく締める。
【0042】
以上によって、図10(B)に示す状態となって、PDP用コネクタ30BのPDP10への接続が完了する。即ち、第1、第2のコンタクト部41a、51aの弾性力によって、第1、第2のコンタクト部41a、51aとねじ104.105の先端部がガラス基板11の端部11aを挟んで、PDP用コネクタ30AはPDP10に機械的に接続される。また、第1、第2のコンタクト部41a、51aが夫々パッド14,15に弾性的に接触されて、PDP用コネクタ30AがPDP10と電気的に接続される。
【0043】
押しねじ100,101を弛めれば、PDP用コネクタ30AはPDP10から外すことが可能となる。
【0044】
[第3実施例]
図11に示すように、本発明の第3実施例になるPDP用コネクタ30Bは、上記の第1実施例になるPDP用コネクタ30Aにおける楔部材70、71に代えて、ブリッジ部材110を使用した構成である。
【0045】
図11,図12及び図13に示すように、シェル部材60Aの内部に、第1の端子部材保持体40と第2の端子部材保持体50とは重なった状態で、圧入されて組み込まれている。
【0046】
ブリッジ部材110は、台形の山形部111と、山形部111の両端の固定部112、113とよりなる構成であり、ねじ114,115により固定部112、113を脚部64,65に固定されて、脚部64,65の間に渡してある。ブリッジ部材110及びねじ114,115が押し付け機構を構成する。
【0047】
PDP10へ接続する前では、PDP用コネクタ30Bは、図14(A)に示す状態にある。ねじ114,115はねじ孔64a,65aに緩く螺合してあり、ブリッジ部材110はZ2方向に移動しており、山形部111は脚部64,65に対応する高さに位置している。
【0048】
PDP用コネクタ30BのPDP10への接続は、以下の手順で行う。
【0049】
図14(A)に示すように、PDP用コネクタ30Bの凹部80をPDP10のガラス基板11の端部11aと突き当たるまで、ゆるく嵌合させる。次いで、ねじ114,115を締めて、ブリッジ部材110をZ1方向に変位させ、PDP用コネクタ30をPDP10に対してZ2方向に変位させ、第1、第2のコンタクト部41a、51aがパッド14,15と軽く接触する状態とする。この状態で、切欠部61a,61bから覗いて、第1、第2のコンタクト部41a、51aのパッド14,15に対する位置を確認し、PDP用コネクタ30をX1−X2方向に適宜僅かに動かして、第1、第2のコンタクト部41a、51aを夫々パッド14,15上に位置させる。この状態で、ねじ114,115をきつく締める。
【0050】
以上によって、図14(B)に示す状態となって、PDP用コネクタ30BのPDP10への接続が完了する。即ち、ガラス基板11の端部11aがPDP用コネクタ30Bに対して第1、第2のコンタクト部41a、51a側に寄せられ、第1、第2のコンタクト部41a、51aがZ1方向に弾性変形され、この弾性力によって、第1、第2のコンタクト部41a、51aとブリッジ部材110は、台形の山形部111とがガラス基板11の端部11aを挟んだ状態となって、PDP用コネクタ30BはPDP10に機械的に接続される。また、第1、第2のコンタクト部41a、51aが夫々パッド14,15に弾性的に接触されて、PDP用コネクタ30BがPDP10と電気的に接続される。
【0051】
ここで、山形部101がガラス基板11の端部11aに押し当る部分の面積は広く、ガラス基板11が傷む虞れはない。
【0052】
ねじ114、115を弛めれば、PDP用コネクタ30BはPDP10から外すことが可能となる。
【0053】
なお、上記各実施例のPDP用コネクタ30、30A、30Bは、液晶パネルの端の部分への接続にも適用できる。
【0054】
【発明の効果】
以上説明したように、請求項1乃至4の発明によれば、基板の端部に緩く嵌合して、押し付け機構によって寄せられるため、基板の端部及びパッドが擦られることが起きず、基板の端部及びパッドを傷めることを防止出来る。コンタクト部とパッドとの位置合わせは、押し付け機構を最終的な状態とする前になされるため、コンタクト部とパッドとの位置合わせを容易に行うことが出来る。よって、接続の信頼性を向上させることが出来る。請求項2の発明によれば、楔部材が凹部とは反対側から組み込まれるため、楔部材を組み込む作業を基板を無用に擦らないで行うことが出来る。請求項3の発明によれば、押しねじを締める簡単な作業で接続を行うことが出来る。請求項4の発明によれば、ブリッジ部材の山形部が基板の端部に当る面積は広くなり、基板の端部に傷みが更に発生しにくいように出来る。
【0055】
請求項5の発明によれば、シェル部材の天板部の切欠部を通して見て、コンタクト部とパッドとの位置関係を視覚によって確認することが可能となり、押し付け機構を最終的な状態とする前に、コンタクト部とパッドとが一致するように位置関係を調整することを容易に行うことが出来る。

BACKGROUND OF THE INVENTION
The present invention relates to a connector connected to an end of a substrate, and more particularly to a connector connected to an end of a plasma display panel.
[0002]
As shown in FIG. 1A, a plasma display panel (hereinafter referred to as PDP) 10 includes a lower glass substrate 11 whose upper surface has been processed and an upper glass substrate 12 whose lower surface has been processed. It is a laminated structure. Reference numeral 16 denotes a display surface. The end portion 11a of the lower glass substrate 11 projects outward from the periphery of the upper glass substrate 12, and a pad row 13 is formed in this portion. The pad row 13 has a configuration in which the pads 14 and 15 are arranged in a staggered pattern at a pitch of, for example, 0.25 mm.
[0003]
A plasma display panel connector is connected to the edge of the PDP 10 with the end portion 11a of the lower glass substrate 11 interposed therebetween.
[0004]
[Prior art]
As shown in FIG. 1B, a conventional plasma display panel connector (hereinafter referred to as a PDP connector) 20 has a spring-like arm portion 22 at a position of a concave portion 21 that sandwiches an end portion 11a of a glass substrate 11. It is the composition which has. The dimension A of the recess 21 is slightly smaller than the thickness t of the glass substrate 11.
[0005]
The PDP connector 20 is pushed into the end portion 11a of the glass substrate 11 while being elastically deformed so as to expand the arm portion 22, and is fitted into the end portion 11a to be connected.
[0006]
[Problems to be solved by the invention]
For this reason, even if the PDP connector 20 is abutted against the end portion 11a of the glass substrate 11 and the position is adjusted with respect to the pad, a positional shift occurs in the process of inserting the PDP connector 20 and the PDP connector 20 is connected. The position of the contact portion 23a of the terminal member 23 is likely to shift with respect to the pad 15. If this misalignment occurs and the electrical connection is not normal, it is necessary to correct the misalignment, but the correction work is difficult, and it is necessary to pull out the connector 20 and reconnect it. The work was troublesome.
[0007]
Further, in the process of connecting the connector 20 and the process of pulling out the connector 20, the spring-like arm portion 22 rubs the glass substrate 11 and the pad 15, which may damage the glass substrate 11 and the pad 15.
[0008]
Then, an object of this invention is to provide the connector connected to the board | substrate edge part which solved the said subject.
