Description

【０００１】
【発明の属する技術分野】
本発明は、電極端子およびこの電極端子の接触に用いる押圧手段ならびにこれらを用いた電気部品検査用ソケットに係り、特に、耐剥離性に優れた電極端子、および、この電極端子の接触安定性に優れた押圧手段、ならびに、これらを用いた電気部品検査用ソケットに関する。
【０００２】
【従来の技術】
従来から、一方の電極端子に対して他方の電極端子を接触可能とした電極端子が知られている。このような一方の電極端子に対して他方の電極端子を接触可能とした電極端子として、電気部品の品位や動作などの検査に用いる電気部品検査用ソケットを例示して説明する。
【０００３】
一般に、電気部品、例えば液晶表示パネル、エレクトロルミネセンスパネル、プラズマディスプレイパネルなどの各種の表示パネルは、ガラスなどの絶縁性素材により形成された基板上にＩＴＯなどにより形成された多数（複数）の電極端子を備えている。そこで、表示パネルの製造工程においては、駆動用ＩＣタブなどの周辺回路接続前の表示パネルに対して、表示欠陥箇所や表示品位などの検査が行われる。この種の表示パネルの表示あるいは性能などを検査する場合、表示パネルの表示部に駆動用の電力を供給するための表示パネル検査用ソケットと称されるコンタクト部材を備えた電気部品検査用ソケットが使用されている。
【０００４】
この種の電気部品検査用ソケットは、絶縁性を有するポリイミド、ポリエステルなどの樹脂製のフィルム基板上に銅などの薄膜により電気部品としての表示パネルの電極端子の形状に応じた所定のパターンの多数（複数）の電極端子が形成されたコンタクト部材を有している。そして、表示パネルの検査時には、一方の電極端子としての表示パネルの電極端子と、他方の電極端子としての電気部品検査用ソケットのコンタクト部材の電極端子とを重ね合わせて一方の電極端子と他方の電極端子とを相対移動させることによりアライメント調整と称される位置合わせを行った後に、前記電気部品検査用ソケットのコンタクト部材の電極端子の背面側を押圧手段としてのゴム様弾性体などにより形成された弾性支持体の押圧面により押圧して、表示パネルの多数の電極端子と電気部品検査用ソケットのコンタクト部材の多数の電極端子とを弾力的に個別に接触させるようになっている。
【０００５】
ところで、近年の電気部品としての表示パネルなどにおいては、表示部の解像度の向上が図られており、この表示部の解像度の向上にともなって表示パネルの電極端子の高密度化および微細ピッチ化が図られている。そして、表示パネルの電極端子の高密度化および微細ピッチ化にともない、コンタクト部材の電極端子も高密度化および微細ピッチ化が図られている。このコンタクト部材の電極端子の高密度化および微細ピッチ化は、電極端子の長手方向に対して直交する方向の幅を狭く形成することにより対応している。
【０００６】
【発明が解決しようとする課題】
しかしながら前述した従来の一方の電極端子に対して他方の電極端子を接触可能とした電極端子、例えば電気部品たる表示パネルの電極端子に接触する電気部品検査用ソケットのコンタクト部材の幅の狭い電極端子は、フィルム基板との接触面積が小さいので、電気部品検査用ソケットのコンタクト部材の電極端子の背面側を押圧手段としての弾性支持体の押圧面により押圧して、コンタクト部材のフィルム基板および電極端子を表示パネルの電極端子に対して弾力的に接触させる際の電極端子の厚さ方向への押圧力を表示パネルの検査毎に繰り返し加えることで、コンタクト部材の電極端子がフィルム基板から剥離しやすいという問題点があった。特に、表示パネルの電極端子とコンタクト部材の電極端子とを重ね合わせて表示パネルの電極端子とコンタクト部材の電極端子とを軽く接触させて位置合わせを行う場合、コンタクト部材の幅の狭い電極端子をフィルム基板から剥離するように、表示パネルの電極端子による外圧が加わるので、コンタクト部材の電極端子がフィルム基板から剥離しやすいという問題点があった。したがって、従来のコンタクト部材の電極端子は、剥離しやすく、耐久性に劣るという問題点があった。
【０００７】
また、図１０に示すように、近年の表示パネル１の電極端子２としては、図１０に示すガラスなどの絶縁性素材により形成された基板３上にＩＴＯなどからなる電極端子２を直接形成したものばかりではなく、図１１および図１２、あるいは図１３に示すように、電極端子２を平面ほぼ長方形の開口部４を具備する絶縁層５により覆って、絶縁層５（図１０から図１３において絶縁層５の厚さを誇張して示す）の開口部４に表示パネル１の電極端子２の電極露出部２Ａをそれぞれの長手方向をほぼ平行にして凹設した構成のものが、表示パネル１の電極端子２の高密度化および微細ピッチ化した際の電極端子２の耐久性を向上することができるなどの理由により用いられている。このような、絶縁層５の開口部４に電極露出部２Ａを凹設した表示パネル１の電極端子２は、相互に隣位する電極露出部２Ａの間に位置する絶縁層５の間に凹部６が形成されるのが一般的であり、位置合わせを行う場合、図示しないコンタクト部材の幅の狭い電極端子が絶縁層５の凹部６に入り込んで、コンタクト部材の電極端子がフィルム基板から剥離しやすいとともに、コンタクト部材を円滑に移動することができないという問題点があった。
【０００８】
さらに、位置合わせを行った後に、表示パネル１の電極端子２に対して図示しないコンタクト部材の電極端子の背面側を押圧手段としての弾性支持体により押圧する場合、表示パネル１の電極端子２の電極露出部２Ａが絶縁層５の開口部４に凹設されていること、および、図示しないコンタクト部材の弾性支持体の押圧面が電極露出部２Ａ、詳しくは絶縁層５の開口部４の面積より大きく形成されていることなどの理由により、表示パネル１の電極端子２の電極露出部２Ａに対して図示しないコンタクト部材の電極端子を適正に接触させることができない、つまり電極露出部２Ａに対して所定の押圧力で接触するコンタクト部材の電極端子の接触面積が小さくなり、接触安定性に劣るという問題点があった。
【０００９】
さらにまた、コンタクト部材の幅の狭い電極端子は、位置合わせを行った後に、表示パネル１の電極端子２に対してコンタクト部材の電極端子の背面側を押圧手段としての弾性支持体により押圧すると、コンタクト部材の電極端子がフィルム基板とともに弾性変形するので、コンタクト部材の電極端子は、表示パネル１の検査を行う毎にフィルム基板とともに弾性変形を繰り返すので、コンタクト部材の電極端子がフィルム基板から剥離しやすいという問題点があった。
【００１０】
そこで、高密度化および微細ピッチ化をした場合においても耐剥離性、耐接触安定性などに優れた電極端子と、接触安定性に優れた電極端子の接触に用いる押圧手段と、これらを用いた電気部品検査用ソケットとが望まれている。
【００１１】
本発明はこれらの点に鑑みてなされたものであり、高密度化および微細ピッチ化を図った場合においても耐剥離性に優れた電極端子を提供することを第１の目的とし、高密度化および微細ピッチ化を図った場合においても接触安定性に優れた電極端子を提供することを第２の目的とし、高密度化および微細ピッチ化を図った場合においても接触安定性に優れた電極端子の接触に用いる押圧手段を提供することを第３の目的とし、これらの電極端子および／または押圧手段を用いた電気部品検査用ソケットを提供することを第４の目的とする。
【００１２】
【課題を解決するための手段】
前述した目的を達成するため特許請求の範囲の請求項１に記載の本発明の電極端子の特徴は、一方の電極端子に対してフィルム基板上に形成された他方の電極端子を接触可能とした電極端子において、前記他方の電極端子は、直線状に延在する部分を有しており、この直線状に延在する部分の一部に、その長手方向に対して直交する方向の幅の狭い幅狭部を形成し、この幅狭部を前記一方の電極端子に対して接触可能に形成した点にある。そして、このような構成を採用したことにより、例えば、一方の電極端子としての電気部品たる表示パネルの電極端子に接触する他方の電極端子としての電気部品検査用ソケットのコンタクト部材の電極端子の幅の狭い幅狭部は、高密度化および微細ピッチ化を図った場合においても表示パネルの電極端子に確実に接触する。さらに、表示パネルの電極端子に接触する電気部品検査用ソケットのコンタクト部材の電極端子は、幅狭部以外の部位を大きくして電極端子全体としてのフィルム基板との接触面積を大きくすることができるので、電極端子全体としてのフィルム基板に対する耐剥離性を向上させることができ、その結果、長期間に亘り安定した機能を保持することができ耐久性に優れたものとなる。したがって、電極端子の高密度化および微細ピッチ化を図った場合においてもフィルム基板上に形成する各種の電極端子の耐剥離性および耐久性を確実に向上させることができる。
【００１４】
また、特許請求の範囲の請求項２に記載の本発明の電極端子の特徴は、開口部を具備する絶縁層により電極端子を覆って絶縁層の開口部に電極露出部を凹設してなる一方の電極端子に対してフィルム基板上に形成された他方の電極端子を接触可能とした電極端子において、前記他方の電極端子にその長手方向に対して直交する方向の幅の一部を前記電極露出部の長手方向に対して直交する方向の幅より狭くしてなる幅狭接触部を形成し、前記電極露出部に対して前記幅狭接触部の一部をそれぞれの長手方向をほぼ平行にして接触可能に形成した点にある。そして、このような構成を採用したことにより、例えば、一方の電極端子としての電気部品たる表示パネルの電極端子に接触する他方の電極端子としての電気部品検査用ソケットのコンタクト部材の電極端子の幅の狭い幅狭接触部は、高密度化および微細ピッチ化を図った場合においてもフィルム基板とともに弾性変形して表示パネルの電極端子の凹設された電極露出部に入り込んで確実に接触するので、接触安定性を向上することができる。さらに、表示パネルの電極端子の凹設された電極露出部に接触する電気部品検査用ソケットのコンタクト部材の電極端子の幅狭接触子は、幅狭接触部以外の部位を大きくして電極端子全体としてのフィルム基板との接触面積を大きくすることができるので、電極端子全体としてのフィルム基板に対する耐剥離性を向上させることができ、その結果、長期間に亘り安定した機能を保持することができ耐久性に優れたものとなる。さらに、電気部品検査用ソケットのコンタクト部材の電極端子は、幅狭接触部以外の部位を大きくして電極端子全体としてのフィルム基板との接触面積を大きくすることができるので、表示パネルの電極端子の凹設された電極露出部に接触する際に、フィルム基板とともに弾性変形を繰り返した場合においてもフィルム基板に対する耐剥離性を向上させることができ、その結果、長期間に亘り安定した機能を保持することができ耐久性に優れたものとなる。したがって、電気部品の電極端子の電極露出部が絶縁層の開口部に凹設されている場合に電極端子の高密度化および微細ピッチ化を図った場合においても、フィルム基板上に形成する各種の電極端子の耐剥離性および耐久性ならびに接触安定性を確実に向上することができる。
【００１５】
また、特許請求の範囲の請求項３に記載の本発明の電極端子の特徴は、請求項２において、前記幅狭接触部の長手方向の少なくとも一端側に前記幅狭接触部より幅の広い幅広部を形成した点にある。そして、このような構成を採用したことにより、例えば、一方の電極端子としての電気部品たる表示パネルの電極端子に接触する他方の電極端子としての電気部品検査用ソケットのコンタクト部材の電極端子の幅広部は、高密度化および微細ピッチ化を図った場合においても幅狭接触部の長手方向の少なくとも一端側の面積を大きくして電極端子全体としてのフィルム基板との接触面積を大きくすることができるので、電極端子全体としてのフィルム基板に対する耐剥離性をより確実に向上させることができ、その結果、長期間に亘り安定した機能をより確実に保持することができ耐久性に優れたものとなる。したがって、電極端子の高密度化および微細ピッチ化を図った場合においてもフィルム基板上に形成する各種の電極端子の耐剥離性および耐久性をより確実に向上させることができる。
【００１６】
また、特許請求の範囲の請求項４に記載の本発明の電極端子の特徴は、開口部を具備する絶縁層により複数の電極端子を覆って絶縁層の開口部に各電極端子毎に電極露出部を凹設するとともに、相互に隣位する各電極露出部の間に位置する絶縁層に凹部を形成してなる一方の電極端子に対してフィルム基板上に形成された他方の複数の電極端子を個別に接触可能とした電極端子において、前記他方の複数の電極端子にその長手方向に対して直交する方向の幅の一部を前記電極露出部の長手方向に対して直交する方向の幅より狭くしてなる幅狭接触部をそれぞれ形成し、前記電極露出部に対して前記幅狭接触部の一部をそれぞれの長手方向をほぼ平行にして個別に接触可能に形成するとともに、前記各電極端子に前記電極露出部の長手方向に対して直交する方向の幅より広くかつ前記絶縁層に形成した凹部の幅より広い絶縁層当接部を形成した点にある。そして、このような構成を採用したことにより、例えば、一方の電極端子としての電気部品たる表示パネルの電極端子に接触する他方の電極端子としての電気部品検査用ソケットのコンタクト部材の電極端子の幅の狭い幅狭接触部は、高密度化および微細ピッチ化を図った場合においてもフィルム基板とともに弾性変形して表示パネルの電極端子の凹設された電極露出部に入り込んで確実に接触するので、接触安定性を向上することができる。さらに、絶縁層当接部は、幅狭接触部以外の部位を大きくして電極端子全体としてのフィルム基板との接触面積を大きくすることができるので、電極端子全体としてのフィルム基板に対する耐剥離性を向上させることができ、その結果、長期間に亘り安定した機能を保持することができ耐久性に優れたものとなる。さらに、絶縁層当接部は、電極端子全体としてのフィルム基板との接触面積を大きくすることができるので、幅狭接触部が電気部品の電極端子の凹設された電極露出部に接触する際に、フィルム基板とともに弾性変形を繰り返した場合においてもフィルム基板に対する耐剥離性を向上させることができ、その結果、長期間に亘り安定した機能を保持することができ耐久性に優れたものとなる。さらにまた、絶縁層当接部は、位置合わせを行う場合、表示パネルの絶縁層と当接するので、表示パネルの絶縁層に形成された凹部に幅狭接触部が入り込むのを確実に防止することができ、その結果、電極端子全体としてのフィルム基板に対する耐剥離性を向上させることができるとともに、コンタクト部材を円滑に移動することもできる。したがって、電気部品の電極端子の電極露出部が絶縁層の開口部に凹設されている場合に電極端子の高密度化および微細ピッチ化を図った場合においても、フィルム基板上に形成する各種の電極端子の耐剥離性および耐久性ならびに接触安定性を確実に向上することができる。
【００１７】
また、特許請求の範囲の請求項５に記載の本発明の電極端子の特徴は、請求項４において、前記幅狭接触部の長手方向の少なくとも一端側に前記絶縁層当接部を形成した点にある。そして、このような構成を採用したことにより、例えば、一方の電極端子としての電気部品たる表示パネルの電極端子に接触する他方の電極端子としての電気部品検査用ソケットのコンタクト部材の電極端子の絶縁層当接部は、高密度化および微細ピッチ化を図った場合においても幅狭接触部の長手方向の少なくとも一端側の面積を大きくして電極端子全体としてのフィルム基板との接触面積を大きくすることができるので、電極端子全体としてのフィルム基板に対する耐剥離性をより確実に向上させることができ、その結果、長期間に亘り安定した機能をより確実に保持することができ耐久性に優れたものとなる。したがって、電極端子の高密度化および微細ピッチ化を図った場合においてもフィルム基板上に形成する各種の電極端子の耐剥離性および耐久性をより確実に向上させることができる。
【００１８】
また、特許請求の範囲の請求項６に記載の本発明の電極端子の接触に用いる押圧手段の特徴は、請求項２、請求項３、請求項４又は請求項５に記載の電極端子の背面側に配設され、一方の電極端子の電極露出部の面積より大きいほぼ平坦な押圧面を具備する弾性支持体を有し、この弾性支持体の押圧面のうちの幅狭接触部の前記電極露出部と対向する部位を強圧するように形成した点にある。ここでいう押圧面のうちの幅狭接触部の電極露出部と対向する部位を強圧するとは、例えば電気部品たる表示パネルの電極端子に接触する電気部品検査用ソケットのコンタクト部材の電極端子の背面側に配設される押圧手段をゴム様弾性体からなる弾性支持体により形成し、この弾性支持体のコンタクト部材の電極端子と対向する部位に電極露出部の面積より大きいほぼ平坦な押圧面を形成するとともに、押圧面のうちの電極露出部と対向する部位のゴム硬さをそれ以外の部位より高く形成したり、押圧面のうちの電極露出部と対向する部位の下部に押圧面とソケット本体の上面との間の間隔をそれ以外の部位より狭くするためのリブを形成したり、コンタクト部材の電極端子の背面側の電極露出部と対向する部位に部分的に凸部を銅箔パターンなどにより設けたりすることなどにより達成することができる。そして、このような構成を採用したことにより、例えば、一方の電極端子としての電気部品たる表示パネルの電極端子に接触する他方の電極端子としての電気部品検査用ソケットの電極端子の押圧手段としてのゴム様弾性体からなる弾性支持体の押圧面は、幅狭接触部が表示パネルの電極端子の凹設された電極露出部に接触する際に、幅狭接触部の電極露出部と対向する部位を強く押圧して幅狭接触部の電極露出部と対向する部位をフィルム基板とともに弾性変形させて電極露出部に確実に当接させることができ、その結果、幅狭接触部と凹設された電極露出部との接触安定性を確実に向上することができる。したがって、電極端子の高密度化および微細ピッチ化を図った場合においても、電気部品に対するフィルム基板上に形成する各種の電極端子の接触安定性を確実に向上することができる。
【００１９】
また、特許請求の範囲の請求項７に記載の本発明の電気部品検査用ソケットの特徴は、請求項１、請求項２、請求項３、請求項４又は請求項５に記載の電極端子を有する点にある。そして、このような構成を採用したことにより、請求項１、請求項３又は請求項５に記載の電極端子を有する場合には耐剥離性および耐久性に優れた電極端子を備えた電気部品検査用ソケットを容易に実現することができ、請求項２又は請求項４に記載の電極端子を有する場合には剥離性および耐久性ならびに接触安定性に優れた電極端子を備えた電気部品検査用ソケットを容易に実現することができる。
【００２０】
また、特許請求の範囲の請求項８に記載の本発明の電気部品検査用ソケットの特徴は、請求項６に記載の押圧手段を有する点にある。そして、このような構成を採用したことにより、電気部品の電極端子に対して接触安定性に優れた電気部品検査用ソケットを容易に実現することができる。
【００２１】
【発明の実施の形態】
以下、本発明を図面に示す実施形態により説明する。
【００２２】
図１は本発明に係る電極端子を用いた本発明に係る電気部品検査用ソケットの第１実施形態の要部を示す概略平面図である。
【００２３】
本実施形態の電気部品検査用ソケットは、電気部品、例えば、液晶表示パネル、エレクトロルミネセンスパネル、プラズマディスプレイパネルなどの各種の表示パネルを用いる場合の、いわゆる表示パネル検査用ソケットの例を示してある。また、本実施形態の電気部品検査用ソケットの電極端子を除く構成については、従来公知のものと同様とされている。よって、本実施形態の電気部品検査用ソケットにおいては、電極端子の構成に係わる要部の構成についてのみ説明し、その他の構成の詳しい説明については省略する。さらにまた、電気部品の電極端子の構成については、前述したように高密度化および微細ピッチ化を図ったものであり、前述したものと同一の構成については図面中に同一の符号を付しその詳しい説明は省略する。
【００２４】
図１に示すように、本実施形態の電気部品検査用ソケット３０の他方の電極端子としてのコンタクト部材３１の電極端子１０は、絶縁性を有するポリイミド、ポリエステルなどの樹脂により製せられたフィルム基板３２上に銅やアルミニウムなどの薄膜によりほぼ櫛歯状に形成されている。すなわち、本実施形態の電極端子１０は、従来と同様に、一方の電極端子との電気的な接続に用いる直線状に延在する部分を有しており、この直線状に延在する部分が相互に平行に配列されている。この電極端子１０の形状は、前述した一方の電極端子としての電気部品たる表示パネル１の電極端子２（図１０から図１３参照）の形状や設計コンセプトなどの必要に応じて決定すればよく、特に、本実施形態の形状に限定されるものではない。
【００２５】
前記電極端子１０の直線状に延在する部分の図１左右方向に示す長手方向の一部には、図１左右方向に示す電極端子１０の直線状に延在する部分の長手方向に対して直交する図１上下に示す方向の幅の狭い幅狭部１１が形成されている。そして、幅狭部１１のうちの図１に２本の鎖線の間に挟まれた、図１左右方向に示す電極端子１０の長手方向の中央部分の大部分が、電気部品たる表示パネル１の電極端子２と接触する接触部１２とされている。すなわち、本実施形態の他方の電極端子１０は、直線状に延在する部分を有しており、この直線状に延在する部分の一部に、その長手方向に対して直交する方向の幅の狭い幅狭部１１が形成されており、この幅狭部１１が一方の電極端子２に対して接触可能に形成されている。したがって、幅狭部１１の図１左右に示す長手方向の両端側には、幅狭部１１より図１上下に示す方向の幅の広い幅広部１３が形成されている。なお、幅広部１３は、図１左右に示す電極端子１０の幅狭部１１の長手方向の少なくとも一方に形成されていればよい。

つぎに、前述した構成からなる本実施形態の作用について説明する。
【００２７】
本実施形態の電気部品検査用ソケット３０の電極端子１０によれば、一方の電極端子としての電気部品たる表示パネル１の電極端子２（図１０から図１３参照）に接触する他方の電極端子としての電気部品検査用ソケット３０のコンタクト部材３１の電極端子１０には、直線状に延在する部分が設けられており、この直線状に延在する部分の一部に、その長手方向に対して直交する方向の幅の狭い幅狭部１１が形成されており、この幅狭部１１の接触部１２は、電極端子の高密度化および微細ピッチ化を図った場合においても表示パネル１の電極端子２に確実に接触する。さらに、電極端子１０は、幅狭部１１以外の部位を大きくして電極端子１０全体としてのフィルム基板３２との接触面積を大きくすることができるので、電極端子１０全体としてのフィルム基板３２に対する耐剥離性を向上させることができ、その結果、長期間に亘り安定した機能を保持することができ耐久性に優れたものとすることができる。また、幅狭部１１の長手方向の両端側に形成された幅広部１３は、電極端子の高密度化および微細ピッチ化を図った場合においても幅狭部１１の長手方向の少なくとも一端側、本実施形態においては両端側の面積を大きくして電極端子１０全体としてのフィルム基板３２との接触面積を大きくすることができるので、電極端子１０全体としてのフィルム基板３２に対する耐剥離性をより確実に向上させることができ、その結果、長期間に亘り安定した機能をより確実に保持することができ耐久性に優れたものとすることができる。
【００２８】
したがって、本実施形態の電極端子１０によれば、電極端子の高密度化および微細ピッチ化を図った場合においても耐剥離性および耐久性を確実に向上することができる。
【００２９】
また、本実施形態の電気部品検査用ソケット３０によれば、耐剥離性および耐久性に優れた電極端子１０を容易に実現することができるので、長期間に亘り安定した機能を確実に保持することができる。
【００３０】
図２は本発明に係る電極端子を用いた本発明に係る電気部品検査用ソケットの第２実施形態の要部を示すものであり、本実施形態の電気部品検査用ソケットは、電気部品たる表示パネルの電極端子間のショートの検査に用いるため、前述した第１実施形態の電気部品検査用ソケットの電極端子の変形例を示したものであり、その他の構成は前述した第１実施形態と同様の構成とされている。よって、本実施形態の電気部品検査用ソケットにおいては電極端子の構成に係わる要部についてのみ説明し、その他の構成の説明は省略する。また、前述した実施形態のものと同一ないし相当する構成については、図面中に同一の符号を付し、その詳しい説明は省略する。
【００３１】
図２に示すように、本実施形態の電気部品検査用ソケット３０Ａのコンタクト部材３１Ａの電極端子１０Ａは、前述した第１実施形態のほぼ櫛歯状の電極端子１０を２組１対として噛み合うように配設するとともに、それぞれの電極端子１０の接触部１２が相互に平行に延在するようにして間隔をおいて交互に繰り返し配置されている。
【００３２】
このような構成の本実施形態の電気部品検査用ソケット３０Ａのコンタクト部材３１Ａの電極端子１０Ａによれば、前述した第１実施形態の電極端子１０と同様の効果を奏することができる。
【００３３】
また、本実施形態の電気部品検査用ソケット３０Ａによれば、耐剥離性および耐久性に優れた電極端子１０を容易に実現することができるので、長期間に亘り安定した機能を確実に保持することができる。
【００３４】
図３は本発明に係る電極端子を用いた本発明に係る電気部品検査用ソケットの第３実施形態の要部を示すものであり、本実施形態の電気部品検査用ソケットは、前述した第１実施形態の電気部品検査用ソケットの電極端子のさらに他の変形例を示したものであり、その他の構成は前述した第１実施形態と同様の構成とされている。よって、本実施形態の電気部品検査用ソケットにおいては電極端子の構成に係わる要部についてのみ説明し、その他の構成の説明は省略する。また、前述した実施形態のものと同一ないし相当する構成については、図面中に同一の符号を付し、その詳しい説明は省略する。
【００３５】
図３に示すように、本実施形態の電気部品検査用ソケット３０Ｂのコンタクト部材３１Ｂの電極端子１０Ｂは、絶縁性を有するポリイミド、ポリエステルなどの樹脂により製せられたフィルム基板３２上に、銅などの薄膜によりほぼ櫛歯状に形成されている。この電極端子１０Ｂの形状は、一方の電極端子としての電気部品たる表示パネル１の電極端子２（図１０から図１３参照）の形状や設計コンセプトなどの必要に応じて決定すればよく、特に、本実施形態の形状に限定されるものではない。
【００３６】
前記電極端子１０Ｂの図３左右方向に示す長手方向の一部には、図３左右方向に示す電極端子１０Ｂの長手方向に対して直交する図３上下に示す方向の幅の狭い幅狭接触部１１Ｂが形成されている。この幅狭接触部１１Ｂの幅寸法ＬＡは、図１０に示す電気部品たる表示パネル１の絶縁層５のない場合の電極端子２の幅寸法Ｌ１あるいは図１２および図１３に示す電気部品たる表示パネル１の絶縁層５を有する場合の絶縁層５の開口部４に形成された電極端子２の電極露出部２Ａの幅寸法Ｌ１（図１２、図１３参照）より小さく（ＬＡ＜Ｌ１）形成されている。そして、幅狭接触部１１Ｂのうちの図３に２本の鎖線の間に挟まれた、図３左右方向に示す電極端子１０Ｂの幅狭接触部１１Ｂの図３左右方向に示す電極端子１０Ｂの長手方向の中央部分の大部分が、電気部品たる表示パネル１の電極端子２あるいは電極露出部２Ａと接触する接触部１２Ｂとされている。
【００３７】
前記幅狭接触部１１Ｂの図３左右に示す長手方向の両端側には、幅狭接触部より幅の広い幅広部１３Ｂが形成されている。この幅広部１３Ｂの幅寸法ＬＢは、図１０に示す電気部品たる表示パネル１の絶縁層のない場合の相互に隣位する電極端子２の間の幅寸法Ｌ２あるいは図１２および図１３に示す電気部品たる表示パネル１の絶縁層５を有する場合の絶縁層５の開口部４に形成された電極端子２の相互に隣位する電極露出部２Ａの間に位置する絶縁層５の間の凹部６の幅寸法Ｌ２（図１２、図１３参照）より大きく（ＬＢ＞Ｌ２）形成されており、表示パネル１の検査時において表示パネル１の絶縁層５に当接する絶縁層当接部１３ＢＡとしても機能するようになっている。なお、幅広部１３Ｂは、図３左右に示す電極端子１０Ｂの長手方向の少なくとも一方に形成されていればよい。
【００３８】
このような構成の本実施形態の電気部品検査用ソケット３０Ｂの電極端子１０Ｂによれば、一方の電極端子としての電気部品たる表示パネル１の電極端子２に接触する他方の電極端子としての電気部品検査用ソケット３０Ｂのコンタクト部材３１Ｂの電極端子１０Ｂには、表示パネル１の電極端子２の電極露出部２Ａの幅寸法Ｌ１より幅の狭い幅狭接触部１１Ｂが形成されており、この幅狭接触部１１Ｂの接触部１２Ｂは、電極端子の高密度化および微細ピッチ化を図った場合においても表示パネル１の絶縁層５を有しない場合の電極端子２に確実に接触させることができる。また、幅狭接触部１１Ｂの接触部１２Ｂは、表示パネル１の絶縁層５を有する場合の凹設された電極端子２の電極露出部２Ａに対しては、フィルム基板３２とともに弾性変形して表示パネル１の電極端子２の凹設された電極露出部２Ａに入り込んで確実に接触するので、接触安定性を向上することができる。また、表示パネル１の電極端子２あるいは電極露出部２Ａに接触する電極端子１０Ｂは、幅狭接触部１１Ｂ以外の部位を大きくして電極端子１０Ｂ全体としてのフィルム基板３２との接触面積を大きくすることができるので、電極端子１０Ｂ全体としてのフィルム基板３２に対する耐剥離性を向上させることができ、その結果、長期間に亘り安定した機能を保持することができ耐久性に優れたものとなる。
【００３９】
また、電極端子１０Ｂの幅狭接触部１１Ｂの長手方向の両端側に形成された幅広部１３Ｂは、電極端子の高密度化および微細ピッチ化を図った場合においても幅狭接触部１１Ｂの長手方向の少なくとも一端側、本実施形態においては両端側の面積を大きくして電極端子１０Ｂ全体としてのフィルム基板３２との接触面積を大きくすることができるので、電極端子１０Ｂ全体としてのフィルム基板３２に対する耐剥離性をより確実に向上させることができ、その結果、長期間に亘り安定した機能をより確実に保持することができ耐久性に優れたものとすることができる。さらに、絶縁層５の間の凹部６の幅寸法Ｌ２より大きく（ＬＢ＞Ｌ２）形成された幅広部１３でもある絶縁層当接部１３ＢＡは、表示パネル１の検査時において位置合わせを行う場合、表示パネル１の絶縁層５と当接して、表示パネル１の絶縁層５に形成された凹部６に幅狭接触部１１Ｂが入り込むのを確実に防止することができ、その結果、電極端子１０全体としてのフィルム基板３２に対する耐剥離性を向上させることができるとともに、コンタクト部材３１を円滑に移動させることができる。
【００４０】
したがって、本実施形態の電極端子１０Ｂによれば、電極端子の高密度化および微細ピッチ化を図った場合に、電気部品たる表示パネル１の電極端子２の電極露出部２Ａが絶縁層５の開口部４に凹設されている場合においても、フィルム基板３２上に形成する電極端子１０Ｂの耐剥離性および耐久性ならびに接触安定性を確実に向上することができる。
【００４１】
また、本実施形態の電気部品検査用ソケット３０Ｂによれば、耐剥離性および耐久性ならびに接触安定性に優れた電極端子１０Ｂを容易に実現することができるので、長期間に亘り安定した機能を確実に保持することができる。
【００４２】
図４は本発明に係る電極端子および本発明に係る電極端子の接触に用いる押圧手段を用いた本発明に係る電気部品検査用ソケットの第４実施形態の位置合わせ状態の要部を示す概略断面図である。
【００４３】
本実施形態の電気部品検査用ソケットは、電気部品、例えば、液晶表示パネル、エレクトロルミネセンスパネル、プラズマディスプレイパネルなどの各種の表示パネルを用いる場合の、いわゆる表示パネル検査用ソケットの例を示してある。また、本実施形態の電気部品検査用ソケットのコンタクト部材の電極端子の構成については、前述した図３に示す第３実施形態の電極端子が用いられている。さらにまた、電気部品たる表示パネルの電極端子の構成については、前述した図１２に示す電極露出部を有する電極端子が用いられている。よって、本実施形態の電気部品検査用ソケットにおいては、電極端子の接触に用いる押圧手段に係わる要部の構成についてのみ説明し、その他の構成の詳しい説明については省略する。また、前述した実施形態のものと同一ないし相当する構成については、図面中に同一の符号を付し、その詳しい説明は省略する。
【００４４】
図４に示すように、本実施形態の電気部品検査用ソケット３０Ｃは、ほぼ四角枠状に形成されたソケット本体３５を有している。そして、ソケット本体３５には、図４に示す表示パネル１の表示部７と電極端子２とが下を向くようにして装着される。そのためソケット本体３５の図４上方に示す上面側には、電極端子２と接触させられる所定パターンの電極端子１０Ｂ（図３参照）を有するコンタクト部材３１Ｂが所定の間隔をおいて配設されている。このコンタクト部材３１Ｂの電極端子１０Ｂの図４下方に示す背面側には、電気部品たる表示パネル１の電極端子２の電極露出部２Ａ（図１２、図１３参照）と、コンタクト部材３１Ｂの電極端子１０Ｂの接触部１２Ｂとを弾力的に押圧して接触させる押圧手段としての、ゴム様弾性体、例えばシリコーンゴムの成形品などからなる弾性支持体４０が突設されている。
【００４５】
この弾性支持体４０は、コンタクト部材３１Ｂの電極端子１０Ｂの配列方向に沿って延びており、弾性支持体４０の図４上方に示す上面には、前記電極露出部２Ａの面積より大きいほぼ平坦な押圧面４１が形成されている。そして、弾性支持体４０の下部には装着部４２が形成されており、この装着部４２をソケット本体３５の上面に形成された装着溝３６に挿入することにより、弾性支持体４０がソケット本体３５に固着されるようになされている。さらに、ソケット本体３５の装着溝３６の図４左右に示す短手方向のほぼ中央部には、弾性支持体４０の押圧面４１のうちの前記電極露出部２Ａと対向する部位の下方に位置する押圧面４１とソケット本体３５の上面との間の間隔Ｄを、それ以外の部位における押圧面４１とソケット本体３５の上面との間の間隔ＤＯより狭くするためのリブ３７がその先端をソケット本体３５の上面から上方に突出するようにして上方に向けて突設されている。このリブ３７の図４左右に示す方向の長さは、電極端子１０Ｂの幅狭接触部１１Ｂの接触部１２Ｂの長さ、言い替えると電極露出部２Ａの長手方向の長さとほぼ同等かあるいは若干短くされており、コンタクト部材３１Ｂの電極端子１０Ｂの配列方向に沿って延びている。そして、弾性支持体４０の下部には、リブ３７が挿入されるリブ用穴４３が形成されている。これらにより、弾性支持体４０の押圧面４１のうちの前記電極露出部２Ａと対向する部位が強圧当接部４１ａとされ、それ以外の部位が低圧当接部４１ｂとされている。
【００４６】
なお、前記リブ３７を複数に分割して、前記電極露出部２Ａと対向する部位にのみ設ける構成としてもよい。
【００４７】
また、押圧面４１に強圧当接部４１ａと低圧当接部４１ｂとを形成する他の例としては、強圧当接部４１ａを硬さの高いゴムにより形成し、低圧当接部４１ｂを強圧当接部４１ａより硬さの低いゴムにより形成する構成を例示することができる。この場合には、必ずしもリブ３７を設ける必要はない。もちろん、押圧面４１に強圧当接部４１ａと低圧当接部４１ｂとを形成する構成は、他の公知の構成であってもよい。
【００４８】
さらにまた、電気部品検査用ソケット３０Ｃとしては、押圧面４１とコンタクト部材３１のフィルム基板３２との間に公知の摺動シートを介在させる構成としてもよい。
【００４９】
またさらに、電気部品検査用ソケット３０Ｃとしては、電極端子１０Ｂのかわりに、前述した各電極端子１０，１０Ａを用いる構成としてもよい。
【００５０】
つぎに、前述した構成からなる本実施形態の作用について図４から図７により説明する。
【００５１】
図５は図４の電気部品検査用ソケットの検査状態の要部を示す概略断面図、図６は図５の６−６線に沿った側断面図、図７は図５の７−７線に沿った側断面図である。
【００５２】
本実施形態の電気部品検査用ソケット３０Ｃの電極端子１０Ｂの接触に用いる押圧手段としての弾性支持体４０によれば、表示パネル１の電極端子２の電極露出部２Ａとコンタクト部材３１Ｂの電極端子１０Ｂの幅狭接触部１１Ｂの接触部１２Ｂとの位置合わせを行う場合には、図４に示すように、弾性支持体４０の上面に形成された電極露出部２Ａの面積より大きい面積の押圧面４１が、電極端子１０Ｂの背面側に位置するので、表示パネル１の検査時の位置合わせ時には、一方の電極端子としての表示パネル１の電極端子２の電極露出部２Ａと、他方の電極端子としての電気部品検査用ソケット３０Ｃのコンタクト部材３１Ｂの電極端子１０Ｂの接触部１２Ｂとを重ね合わせて電極露出部２Ａと接触部１２Ｂとを容易かつ円滑に相対移動させることができる。
【００５３】
また、表示パネル１の検査時において、コンタクト部材３１Ｂの電極端子１０Ｂの幅狭接触部１１Ｂの接触部１２Ｂが表示パネル１の電極端子２の凹設された電極露出部２Ａに接触する際には、図５および図６に示すように、押圧面４１のうちの強圧当接部４１ａが、電極端子１０Ｂの幅狭接触部１１Ｂの電極露出部２Ａと対向する部位、すなわち接触部１２Ｂを強く押圧して接触部１２Ｂをフィルム基板３２とともに弾性変形させて表示パネル１の電極露出部２Ａの内部に接触部１２Ｂを入り込ませることができる。この時、押圧面４１のうちの低圧当接部４１ｂは、図５および図７に示すように、電極端子１０Ｂの接触部１２Ｂ以外の幅広部１３Ｂとしての絶縁層当接部１３ＢＡを表示パネル１の絶縁層５に弱く押圧する。
【００５４】
このような構成の本実施形態の電気部品検査用ソケット３０Ｃの電極端子の接触に用いる押圧手段としての弾性支持体４０によれば、表示パネル１の検査時において、弾性支持体４０の押圧面４１のうちの強圧当接部４１ａが幅狭接触部１１Ｂのうちの接触部１２Ｂの電極露出部２Ａと対向する部位を強く押圧して接触部１２Ｂをフィルム基板３２とともに弾性変形させて電極露出部２Ａに確実に当接させることができ、その結果、幅狭接触部１１Ｂの接触部１２Ａと凹設された電極露出部２Ａとの接触安定性を確実に向上することができる。
【００５５】
したがって、本実施形態の電極端子１０Ｂの接触に用いる押圧手段としての弾性支持体４０によれば、電極端子の高密度化および微細ピッチ化を図った場合においても、電気部品たる表示パネル１に対するフィルム基板３２上に形成する電極端子１０Ｂの接触安定性を確実に向上することができる。なお、電極端子１０Ｂのかわりに、前述した各電極端子１０，１０Ａを用いる構成とした場合であっても、各電極端子１０，１０Ａの接触安定性を確実に向上することができる。すなわち、各種の電極端子の接触安定性を確実に向上することができる。
【００５６】
また、本実施形態の電気部品検査用ソケット３０Ｃによれば、接触安定性に優れた押圧手段を容易に実現することができるので、長期間に亘り安定した機能を確実に保持することができる。
【００５７】
図８および図９は本発明に係る電極端子および本発明に係る電極端子の接触に用いる押圧手段を用いた本発明の電気部品検査用ソケットの第５実施形態を示すものであり、図８は位置合わせ状態を示す要部の概略断面図、図９は検査状態を示す要部の概略断面図である。
【００５８】
本実施形態の電気部品検査用ソケットは、前述した図４に示す第４実施形態の電気部品検査用ソケットの押圧手段の変形例を示すものであり、その他の構成は前述した図４に示す第４実施形態の電気部品検査用ソケットと同様とされている。よって、本実施形態の電気部品検査用ソケットにおいては、押圧手段に係わる要部についてのみ説明し、その他の構成の説明は省略する。また、前述した図４に示す実施形態のものと同一ないし相当する構成については、図面中に同一の符号を付し、その詳しい説明は省略する。
【００５９】
図８に示すように、本実施形態の電気部品検査用ソケット３０Ｄは、ほぼ四角枠状に形成されたソケット本体３５Ｄを有しており、このソケット本体３５Ｄの図８上方に示す上面側には、電極端子２と接触させられる所定パターンの電極端子１０Ｂ（図３参照）を有するコンタクト部材３１Ｄが所定の間隔をおいて配設されている。このコンタクト部材３１Ｄの電極端子１０Ｂの図８下方に示すフィルム基板３２の背面側の電極露出部２Ａと対向する部位には、押圧手段４０Ｄの一部を構成する凸部４０Ｄａが設けられている。この凸部は、例えば、フィルム基板３２の背面側の電極露出部２Ａと対向する部位に、電極端子１０Ｂの幅狭接触部１１Ｂの幅寸法ＬＡより短く、電極露出部２Ａの長手方向の長さより短い範囲で銅箔パターンを形成することにより設けられている。
【００６０】
また、ソケット本体３５Ｄのコンタクト部材３１Ｄの電極端子１０Ｂの図８下方に示す背面側には、電気部品たる表示パネル１の電極端子２の電極露出部２Ａ（図１２、図１３参照）と、コンタクト部材３１Ｄの電極端子１０Ｂの接触部１２Ｂとを弾力的に押圧して接触させるための押圧手段４０Ｄの一部を構成するゴム様弾性体、例えばシリコーンゴムの成形品などからなる断面ほぼ四角形の弾性支持体４０Ｄｂが突設されている。この弾性支持体４０Ｄｂは、コンタクト部材３１Ｄの電極端子１０Ｂの配列方向に沿って延びており、弾性支持体４０Ｄの図８上方に示す上面には、前記電極露出部２Ａの面積より大きいほぼ平坦な押圧面４１Ｄが形成されている。そして、弾性支持体４０Ｄｂの下部をソケット本体３５Ｄの上面に形成された断面ほぼ四角形の装着溝３６Ｄに挿入することにより、弾性支持体４０Ｄｂがソケット本体３５Ｄに固着されるようになされている。
【００６１】
このような構成の本実施形態の電気部品検査用ソケット３０Ｄの電極端子１０Ｂの接触に用いる押圧手段４０Ｄによれば、表示パネル１の電極端子２の電極露出部２Ａとコンタクト部材３１Ｄの電極端子１０Ｂの幅狭接触部１１Ｂの接触部１２Ｂとの位置合わせを行う場合には、図８に示すように、押圧手段４０Ｄの一部を構成する弾性支持体４０Ｄｂの上面に形成された電極露出部２Ａの面積より大きい面積の押圧面４１Ｄが、電極端子１０Ｂの背面側に位置するので、表示パネル１の検査時の位置合わせ時には、一方の電極端子としての表示パネル１の電極端子２の電極露出部２Ａと、他方の電極端子としての電気部品検査用ソケット３０Ｄのコンタクト部材３１Ｄの電極端子１０Ｂの接触部１２Ｂとを重ね合わせて電極露出部２Ａと接触部１２Ｂとを容易かつ円滑に相対移動させることができる。
【００６２】
また、表示パネル１の検査時において、コンタクト部材３１Ｄの電極端子１０Ｂの幅狭接触部１１Ｂの接触部１２Ｂが表示パネル１の電極端子２の凹設された電極露出部２Ａに接触する際には、図９に示すように、弾性支持体４０Ｄｂの押圧面４１Ｄのうちの一部が凸部４０Ｄａを介してフィルム基板３２に当接するので、電極端子１０Ｂの幅狭接触部１１Ｂの電極露出部２Ａと対向する部位、すなわち接触部１２Ｂを強く押圧して接触部１２Ｂをフィルム基板３２とともに弾性変形させて表示パネル１の電極露出部２Ａの内部に接触部１２Ｂを入り込ませることができる。この時、押圧面４１のうちの凸部４０Ｄａと当接しない部位は、電極端子１０Ｂの接触部１２Ｂ以外の幅広部１３Ｂとしての絶縁層当接部１３ＢＡを表示パネル１の絶縁層５に弱く押圧する。
【００６３】
このような構成の本実施形態の電気部品検査用ソケット３０Ｄの押圧手段４０Ｄによれば、前述した第４実施形態の押圧手段としての弾性支持体４０と同様の効果を奏することができる。
【００６４】
また、本実施形態の電気部品検査用ソケット３０Ｄによれば、前述した第４実施形態の電気部品検査用ソケット３０Ｃと同様に、接触安定性に優れた押圧手段を容易に実現することができるので、長期間に亘り安定した機能を確実に保持することができる。
【００６５】
なお、本発明が表示パネル以外の電気部品、例えば半導体集積回路（ＩＣ）や複数の電気部品が搭載されている回路基板などについても適用可能であることは言うまでもない。
【００６６】
また、本発明は前記各実施形態に限定されるものではなく、必要に応じて変更することができる。
【００６７】

The present invention relates to excellent pressing means and an electrical component inspection socket using the same.

[Prior art]
2. Description of the Related Art Conventionally, an electrode terminal that allows one electrode terminal to contact the other electrode terminal has been known. As an example of such an electrode terminal capable of contacting one electrode terminal with the other electrode terminal, an electrical component inspection socket used for inspection of the quality and operation of the electrical component will be described as an example.
[0003]
2. Description of the Related Art In general, various display panels such as an electric component, for example, a liquid crystal display panel, an electroluminescence panel, and a plasma display panel are provided on a substrate formed of an insulating material such as glass by a large number (a plurality) formed of ITO or the like. It has electrode terminals. Therefore, in the manufacturing process of the display panel, the display panel before the connection of the peripheral circuit such as the driving IC tab is inspected for a defective display portion and a display quality. When inspecting the display or performance of this type of display panel, an electrical component inspection socket having a contact member called a display panel inspection socket for supplying driving power to a display unit of the display panel is required. It is used.
[0004]
This type of socket for electrical component inspection has a large number of predetermined patterns corresponding to the shape of electrode terminals of a display panel as an electrical component on a film substrate made of resin such as polyimide or polyester having an insulating property by a thin film of copper or the like. It has a contact member on which a plurality of electrode terminals are formed. When inspecting the display panel, the electrode terminal of the display panel as one electrode terminal and the electrode terminal of the contact member of the electrical component inspection socket as the other electrode terminal are overlapped, and one electrode terminal and the other electrode terminal are overlapped. After performing positioning called alignment adjustment by relatively moving the electrode terminal, the back side of the electrode terminal of the contact member of the socket for electrical component inspection is formed of a rubber-like elastic body or the like as a pressing means. The plurality of electrode terminals of the display panel and the plurality of electrode terminals of the contact member of the electrical component inspection socket are elastically and individually contacted by being pressed by the pressing surface of the elastic support.
[0005]
By the way, in a display panel or the like as an electric component in recent years, the resolution of a display section has been improved, and with the improvement of the resolution of the display section, the density and pitch of electrode terminals of the display panel have been increased. It is planned. As the electrode terminals of the display panel have higher densities and finer pitches, the electrode terminals of the contact members have also higher densities and finer pitches. The higher density and finer pitch of the electrode terminals of the contact member are met by forming the electrode terminals narrower in the direction perpendicular to the longitudinal direction.
[0006]
[Problems to be solved by the invention]
However, the above-described conventional electrode terminal that allows one electrode terminal to contact the other electrode terminal, for example, a narrow electrode terminal of a contact member of an electrical component inspection socket that contacts an electrode terminal of a display panel as an electrical component. Since the contact area with the film substrate is small, the back side of the electrode terminal of the contact member of the electrical component inspection socket is pressed by the pressing surface of the elastic support as the pressing means, and the film substrate and the electrode terminal of the contact member are pressed. The electrode terminal of the contact member is easily peeled off from the film substrate by repeatedly applying the pressing force in the thickness direction of the electrode terminal when making the elastic contact with the electrode terminal of the display panel every time the display panel is inspected. There was a problem. In particular, when the electrode terminal of the display panel and the electrode terminal of the contact member are overlapped and the electrode terminal of the display panel and the electrode terminal of the contact member are lightly contacted for alignment, the electrode terminal having a narrow width of the contact member is used. Since external pressure is applied by the electrode terminals of the display panel so as to separate from the film substrate, there is a problem that the electrode terminals of the contact member are easily separated from the film substrate. Therefore, there has been a problem that the electrode terminals of the conventional contact member are easily peeled off and have poor durability.
[0007]
Further, as shown in FIG. 10, as the electrode terminals 2 of the display panel 1 in recent years, the electrode terminals 2 made of ITO or the like are directly formed on a substrate 3 formed of an insulating material such as glass shown in FIG. As shown in FIG. 11, FIG. 12, or FIG. 13, the electrode terminal 2 is covered with an insulating layer 5 having an opening 4 having a substantially rectangular plane, and the insulating layer 5 (see FIGS. 10 to 13). The display panel 1 has a configuration in which the electrode exposed portions 2A of the electrode terminals 2 of the display panel 1 are recessed in the openings 4 of the insulating layer 5 (the thickness of the insulating layer 5 is exaggerated) so that their longitudinal directions are substantially parallel to each other. The electrode terminals 2 are used for the reason that the electrode terminals 2 can be made denser and have a fine pitch and the durability of the electrode terminals 2 can be improved. Such an electrode terminal 2 of the display panel 1 in which the electrode exposed portion 2A is recessed in the opening 4 of the insulating layer 5 has a concave portion between the insulating layers 5 located between the electrode exposed portions 2A adjacent to each other. In general, when positioning is performed, a narrow electrode terminal (not shown) of the contact member enters the concave portion 6 of the insulating layer 5, and the electrode terminal of the contact member peels off from the film substrate. In addition, there is a problem that the contact member cannot be moved smoothly.
[0008]
Furthermore, when the back side of the electrode terminal of the contact member (not shown) is pressed against the electrode terminal 2 of the display panel 1 by the elastic support as the pressing means after the alignment, the electrode terminal 2 of the display panel 1 is pressed. The electrode exposed portion 2A is recessed in the opening 4 of the insulating layer 5, and the pressing surface of the elastic support of the contact member (not shown) is formed on the electrode exposed portion 2A, specifically, the area of the opening 4 of the insulating layer 5. For example, the electrode terminal of the contact member (not shown) cannot be properly brought into contact with the electrode exposed portion 2A of the electrode terminal 2 of the display panel 1 because of being formed larger. As a result, the contact area of the electrode terminal of the contact member that comes into contact with a predetermined pressing force is reduced, resulting in poor contact stability.
[0009]
Furthermore, when the narrow electrode terminal of the contact member is aligned, and then the back side of the electrode terminal of the contact member is pressed against the electrode terminal 2 of the display panel 1 by an elastic support as pressing means, Since the electrode terminals of the contact member elastically deform together with the film substrate, the electrode terminals of the contact member repeatedly elastically deform together with the film substrate each time the display panel 1 is inspected. There was a problem that it was easy.
[0010]
Therefore, even in the case of high density and fine pitch, an electrode terminal excellent in peeling resistance, contact resistance and the like, and a pressing means used for contacting the electrode terminal excellent in contact stability, and these were used. There is a need for an electrical component inspection socket.
[0011]
The present invention has been made in view of these points, and a first object of the present invention is to provide an electrode terminal excellent in peeling resistance even when high density and fine pitch are achieved. A second object is to provide an electrode terminal having excellent contact stability even when a fine pitch is achieved, and to provide an electrode terminal having excellent contact stability even when a high density and fine pitch are achieved. A third object is to provide a pressing means used for the contact of the electronic component, and a fourth object is to provide an electrical component inspection socket using these electrode terminals and / or the pressing means.

Furthermore, the electrode terminal of the contact member of the socket for electrical component inspection that comes into contact with the electrode terminal of the display panel can increase the area other than the narrow portion to increase the contact area of the electrode terminal with the film substrate as a whole. Therefore, the resistance of the electrode terminal as a whole to the film substrate can be improved, and as a result, a stable function can be maintained for a long period of time and the durability is excellent.

Furthermore, the narrow contact of the electrode terminal of the contact member of the electrical component inspection socket that contacts the recessed electrode exposed portion of the electrode terminal of the display panel is enlarged by increasing the area other than the narrow contact portion to form the entire electrode terminal. As the contact area with the film substrate can be increased, the peel resistance of the electrode terminal as a whole to the film substrate can be improved, and as a result, a stable function can be maintained for a long period of time. It will be excellent in durability. Furthermore, since the electrode terminals of the contact members of the socket for electrical component inspection can have a large area other than the narrow contact portion to increase the contact area of the electrode terminals with the film substrate as a whole, the electrode terminals of the display panel can be enlarged.
