Description

【0001】
【発明の属する技術分野】
本発明は、フレキシブルフラットケーブルやフレキシブルプリント配線基板などのフレキシブル基板と、プリント配線基板等とを電気的に接続するためのフレキシブル基板用コネクタに関するものである。
【0002】
【従来の技術】
従来、この種のフレキシブル基板用コネクタには、フレキシブル基板の挿入時にはコンタクトからの接触圧を受けずに低い挿入力で挿入でき、フレキシブル基板の挿入後には所定の接触圧でコンタクトと接触して安定した電気的接続が得られるゼロ・インサーション・フォース(ZIF)構造のものが知られている。
例えば、フレキシブル基板の挿入時には、スライダをハウジングから出す方向へ移動し、コンタクトからの接続圧を受けずに低い挿入力でフレキシブル基板をハウジング内の所定位置まで挿入し、フレキシブル基板の挿入後には、スライダをハウジングに入る方向へ移動してスライダの押圧片部でフレキシブル基板をコンタクト側へ押圧し、所定の接触圧でコンタクトと接触するように構成されていた。
【0003】
【発明が解決しようとする課題】
しかしながら、前述の従来例では、フレキシブル基板をハウジング内の所定位置まで挿入してからスライダを移動しなければならないため、フレキシブル基板のハウジング内への挿入が不十分なときに、安定した電気的接続が得られないという問題点があった。
また、フレキシブル基板の挿入後においても、スライダの押圧片部がフレキシブル基板をコンタクト側へ押圧しているだけなので、フレキシブル基板の抜け止めが不十分になり易いという問題点があった。
【0004】
本発明は、上述の問題点に鑑みなされたもので、挿入時におけるフレキシブル基板のハウジング内への挿入が不十分なときであってもスライダによってフレキシブル基板をハウジング内の所定位置まで挿入することができ、挿入後においてもフレキシブル基板の抜け止めを強化できるフレキシブル基板用コネクタを提供することを目的とするものである。
【0005】
【課題を解決するための手段】
請求項1の発明によるフレキシブル基板用コネクタは、挿入凹部(15)が形成されたハウジング(1)と、ハウジング(1)内に組み込まれたコンタクト(7〜7)と、挿入凹部(15)への挿抜が可能なスライダ(4)とを具備し、スライダ(4)を挿入凹部(15)へ挿入することによって、挿入凹部(15)に挿入されたフレキシブル基板(8)をコンタクト(7〜7)側へ押圧し、フレキシブル基板(8)の接触部をコンタクト(7〜7)の接触部(74〜74)に接触させるフレキシブル基板用コネクタであって、スライダ(4)のフレキシブル基板(8)を押圧する側の面に、挿入凹部(15)に挿入されるフレキシブル基板(8)の補強材(82)に係合可能な段差部(45,45)を形成し、スライダ(4)の抜去側部分に切り欠き部(44)を形成し、切り欠き部(44)は、スライダ(4)の抜去側とフレキシブル基板(8)を押圧する側とその反対側との3方向に向かって開口して形成され、切り欠き部(44)の抜去側に向かう面と段差部(45,45)が補強材(82)と係合する面とが略同一面上に位置するように形成されていることを特徴とするものである。
【0006】
上述の構成において、フレキシブル基板(8)の挿入時においてフレキシブル基板(8)の挿入凹部(15)内への挿入が不十分な時でも、スライダ(4)の挿入凹部(15)への挿入時に段差部(45,45)がフレキシブル基板(8)の補強材(82)に係合してフレキシブル基板(8)を挿入凹部(15)内の所定位置まで移動させることができる。また、挿入後においては、スライダ(4)の段差部(45,45)がフレキシブル基板(8)の補強材(82)に係合してフレキシブル基板(8)の抜け止めに寄与することができる。
さらに、スライダ(4)の挿入凹部(15)からの抜去側部分に切り欠き部(44)を形成し、この切り欠き部(44)が、スライダ(4)の抜去側とフレキシブル基板(8)を押圧する側とその反対側との3方向に向かって開口し、切り欠き部(44)の抜去側に向かう面と段差部(45,45)が補強材(82)と係合する面とが略同一面上に位置するように形成されているので、フレキシブル基板(8)の補強材(82)がスライダ(4)の段差部(45,45)に係合可能な位置まで挿入されているか否かを切り欠き部(44)を介して目視することができ、フレキシブル基板(8)が挿入凹部(15)内の所定位置まで適切に挿入されているか否かを容易に確認することができる。
【0007】
請求項2の発明は、請求項1に記載の発明において、ハウジング(1)の両側に操作スペースを設けることなくスライダ(4)の移動の容易化を図るために、ハウジング(1)に回動可能に支持され、この回動に連動してスライダ(4)をハウジング(1)側へ移動させる操作レバー(6)を具備したことを特徴とするものである。
【0008】
請求項3の発明は、請求項2の発明において、小型化を維持しつつ操作レバー(6)を十分な強度で回動支持するために、取付片部(21,31)がハウジング(1)の両側壁に固着されてハウジング(1)の側壁との間でスライダ(4)のスライド腕部(42,42)を案内する据え付け具(2,3)を具備し、スライド腕部(42,42)の内壁面に操作レバー(6)の回動腕部(62,62)を回動可能に収容する凹部(49,49)を形成し、回動腕部(62,62)の先端部に取付片部(21,31)の枢支孔(24,34)に回動可能に支持される枢軸(63,63)を形成したことを特徴とするものである。
【0009】
請求項4の発明は、請求項3の発明において、操作レバー(6)の回動でスライダ(4)をハウジング(1)側へ移動してロックするときにクリック感を生じさせるとともに、ロックされた操作レバー(6)が振動等の外力で容易に回動するのを防止するためにスライド腕部(42,42)の内壁面に係合段部(53,53)を形成し、回動腕部(62,62)に、操作レバー(6)の回動時に係合段部(53,53)と所定の押圧力で当接可能な係合突起(67,67)を形成したことを特徴とするものである。
【0010】

【0021】
係合段部53は、上部垂直内壁面54、下部垂直内壁面55及び傾斜内壁面56を具備し、上部垂直内壁面54の内壁面は凹部49の内壁面52と略平行で内壁面52より内側に位置して形成され、下部垂直内壁面55の内壁面は上部垂直内壁面54と略平行で若干外側に位置して形成され、傾斜内壁面56は上部垂直内壁面54と下部垂直内壁面55の間に位置して傾斜段差をもって形成されている。

【0027】
つぎに、図1を用いて組み立て方法について説明する。
(1) まず、ハウジング1のコンタクト収容部18〜18に背面側からコンタクト7〜7を挿入することによってコンタクト7〜7をハウジング1内に組み込む。このとき、コンタクト7の取付片部72は、係止突起を具備しているのでコンタクト収容部18の保持孔18c内に圧入、係止され、コンタクト7の接触片部71はコンタクト収容部18の収容溝18a内に遊嵌状態で収容され、収容溝18a内で上下方向に弾性変形可能となる。
【0028】
(2) ついで、ハウジング1の側板部12,12に形成された係止溝16,16に、据え付け具2,3の取付片部21,31を下部側から圧入、係止することによって据え付け具2,3をハウジング1に組み込む。この組み込みによってハウジング1の一方の側板部12と据え付け具2の外側片部22及び底側片部26とによるU字状の案内部27が形成されるとともに、ハウジング1の他方の側板部12と据え付け具3の外側片部32及び底側片部36とによるU字状の案内部37が形成される。
【0029】
(3) ついで、前記(2)で形成された案内部27,37に、スライダ4のスライド腕部42、42を前面側から挿入することによってスライダ4を組み込む。このとき、スライド腕部42、42の抜け止め突起48、48が据え付け具2,3の案内孔25、35に遊嵌状態で係合し、スライダ4の移動範囲を規制するとともに、スライダ4のハウジング1からの抜け止めとなる。
【0030】
(4) ついで、前記(3)でハウジング1に組み込まれたスライダ4の凹部49、49に操作レバー6の回動腕部62、62を上部側から挿入することによって操作レバー6を組み込む。このとき、操作レバー6の枢軸63、63を据え付け具2,3の枢支孔24、34に挿入し、操作レバー6が枢軸63、63を中心として回動可能となっている。また、組み込まれた操作レバー6を背面側へほぼ90度回動したときには、操作レバー6の係合突起67、67がスライダ4の係合段部53、53に所定の押圧力で当接する。
【0031】
つぎに、前期実施形態例の作用を図12及び図13を併用して説明する。
まず以下の(A)において、操作レバー6の回動に連動してスライダ4が前後方向に移動する作用を説明し、ついで以下の(B)において、ハウジング1の挿入凹部15内にフレキシブル基板8を低い挿入力で挿入し、操作レバー6の回動でスライダ4を移動して押圧片部46がフレキシブル基板8の接触部をコンタクト77〜7の接触部74〜74に弾性接触させる作用について説明する。
【0032】
(A): 操作レバー6の回動によるスライダ4の移動作用
(1) 図12(a)に示す初期状態(出荷状態)は、図2,図3及び図4の状態に該当する。この初期状態では、操作レバー6の後方カム面65、65がスライダ4の後方ホロアー面51、51に当接し、操作レバー6の係合突起67、67がスライダ4の傾斜内壁面56、56に所定の押圧力で当接し、操作レバー6が振動等の外力で点Oを中心として左回りに回動しないように規制されている。
点Oは、据え付け具2,3の枢支孔24、34に回動可能に支持された枢軸63、63の中心を表す。
【0033】
(2) 図12(a)の状態において、操作レバー6を矢印で示す左回り方向に回動すると、前方カム面64、64がスライダ4の前方ホロアー面50、50を押圧してスライダ4を矢印で示す左方向へ移動させ、同図(b)に示す状態となる。
【0034】
(3) 図12(b)の状態において、操作レバー6をさらに矢印で示す左回り方向に回動し、前記(1)の初期状態に対して所定角度(例えば77.3度)回動すると、前方カム面64、64が前方ホロアー面50、50をさらに押圧してスライダ4を矢印で示す左方向に移動させ、同図(c)に示す状態となって移動がとまる。これは、スライダ4の抜け止め突起48、48が据え付け具2,3の案内孔25、35の端部に当接して移動範囲を規制しているからである。
【0035】
(4) 図12(c)の状態は図13(b)の状態に該当し、スライダ4の前面側を水平面Hより若干上方へ移動させてフレキシブル基板8の低挿入での挿入を可能とする。すなわち、図12(c)に示すようにスライダ4が左方向に移動すると、図13(a)に示すように天板部13の前面側内壁面との係合していた押圧片部46の前面側の外壁面が同図(b)に示すように係合を解かれて押圧片部46の背面側の上側壁面と係合し、スライダ4の前面側を水平面Hより若干上方へ移動させるからである。
水平面Hは、フレキシブル基板用コネクタの他方の接続対象であるプリント配線基板等の表面を表す。
【0036】
(5) 図12(c)の状態において、操作レバー6を矢印で示す右回り方向に回動すると、操作レバー6の後方カム面65、65がスライダ4の後方ホロアー面51、51を押圧してスライダ4を矢印で示す右方向へ移動させ同図(d)に示す状態となる。
【0037】
(6) 図12(d)の状態において、操作レバー6をさらに矢印で示す右回り方向に回動すると、後方カム面65、65が後方ホロアー面51、51を矢印で示す右方向に移動させ、同図(e)に示す初期状態に戻る。
このとき、操作レバー6の係合突起67、67は、係合段部53、53との係合において、初めはスライダ4の上部垂直内壁面54,54に所定の押圧力で当接し続けているが、操作レバー6の回動が進んで初期状態に戻る直前にはそれまでの押圧力より小さな押圧力で傾斜内壁面56、56に当接するので、クリック感が生じる。
また、操作レバー6の係合突起67、67が係合段部53、53の傾斜内壁面56、56と係合することによって、操作レバー6が振動等の外力で左回り方向に回動するのを規制している。
【0038】
(B): フレキシブル基板8の挿入、接続作用
(1) 図13(a)に示す初期状態において、操作レバー6を左回り方向に回動すると、前記(A)(2)(3)で説明した作用により、スライダ4が左方向に移動するとともに前面側を水平面Hより上へ移動させる。
このため、図13(b)に示すように、コンタクト7〜7の接触部74〜74とスライダ4の押圧片部46の間にフレキシブル基板8の厚さより広い間隙が確保され、フレキシブル基板8を低挿入力で挿入凹部15内へ挿入することができる。
このフレキシブル基板8の挿入凹部15内への挿入は、通常、フレキシブル基板8の先端部が背板部14の内壁面に当接する位置か、その近傍位置のいわゆる所定位置までとなる。
【0039】
(2) 前記(1)でフレキシブル基板8の挿入凹部15内への挿入が低挿入力で可能な状態において、図13(b)に示すように、フレキシブル基板8の挿入凹部15内への挿入が所定位置まで達しない不十分なときであっても、フレキシブル基板8の補強材82の前面側端部がスライダ4の段差部45、45に係合可能な位置まで挿入されていれば、操作レバー6の右回り方向の回動によるスライダ4の右方向への移動によって、同図(c)に示すように、フレキシブル基板8の先端部を挿入凹部15内の所定位置まで移動させ、フレキシブル基板8の接触部をコンタクト7〜7の接触部74〜74に所定の弾性力で接触させることができる。
すなわち、フレキシブル基板8の不完全挿入を防止して、フレキシブル基板8とプリント配線基板等との電気的な接続を確実にすることができる。
【0040】
(3) 前記(2)でフレキシブル基板8の補強材82の前面側端部がスライダ4の段差部45、45に係合可能な位置まで挿入されているか否かは、スライダ4の切り欠き部44を介して目視することができるので、フレキシブル基板8の挿入凹部15内への仮挿入を容易にすることができるとともに、フレキシブル基板8の挿入凹部15内への挿入状態の確認を容易にすることができる。
【0041】
(4) 図13(b)の挿入状態から同図(c)のロック状態に至る直前においては、前記(A)(6)の作用によりクリック感が生じるので、ロック状態になったことを容易に確認することができる。また、ロック状態になった後には、前A)(6)の作用により記操作レバー6の左回りの回動を規制しているので、振動等の外力でロック解除となるのを防止できる。
【0042】
(5) 図13(c)のロック状態においては、スライダ4の段差部45、45がフレキシブル基板8の補強材82の前面側端部に係合してフレキシブル基板8の抜け止めに寄与しているので、フレキシブル基板8の抜け止めを強化することができる。
【0043】
前期実施形態例では、操作レバー6に前方カム面64、64及び後方カム面65、65を形成するとともに、スライダ4の凹部49、49に前方ホロアー面50、50及び後方ホロアー面51、51を形成した、カム機構を用いた場合について説明したが、本発明はこれに限るものでなく、操作レバー6の回動運動をスライダ4の往復直線運動に変換させるものであれば、リンク機構などの他の機構を用いたものについても利用することができる。
