1229476 玖、發明說明： 【發明所屬之技術領域】 本發明有關於用來將FPC(Flexible Printed Circuit) 等之平形柔軟電纜連接在電路板之電氣連接器。 【先前技術】 習知之電氣連接器具備有外殼，係具有用來插入平形柔 軟電纜之開口部，並藉由被保持在該外殼之多個連接部壓 接在從開口部插入之平形柔軟電纜，用來達成對該平形柔 軟電纜之電氣連接。 在此種電氣連接器中，有可藉由轉動開啟可相對轉動地 被安裝在外殼之蓋子，在多數個連接部的壓接位置形成可 插入平形柔軟電纜之插入空間，使在無插入力下將平形柔 軟電纜插入到該插入空間内者。此種電氣連接器係所謂之 ZIF(Zero Insertion Force)型者，在平形柔軟電纜插入 後，使蓋子閉合時，多個連接部壓接在該平形柔軟電纜， 用來達成電氣連接。 在此種電氣連接器中，例如在使蓋子閉合之狀態，成為 該蓋子受到閉合方向之力之作用，使蓋子不容易開啟。但 是，在製造時，搬運中和使用中等，電氣連接器受到外力（振 動等）之作用之情況時，會造成蓋子之開啟，所裝著之平形 柔軟電纜脫落，或造成蓋子破損之疑慮。 因此提案有一種電氣連接器（參照例如日本專利特開 2 0 0 2 - 2 5 2 0 6 7號公報），藉由在閉合狀態使蓋子滑動到指定 之鎖定位置，使被設在蓋子之接合部，接合在電氣連接器 5 312/發明說明書(補件)/93-06/93108834 1229476 之指定位置（例如，金屬製之補強翼片），可以將蓋子鎖定 在閉合狀態。 但是，在上述方式之電氣連接器中，必需在蓋子所被安 裝之開口部近傍設置鎖定機構用之零件，或是延長設置補 強翼片。因此，最好是以更簡單之構成形成可以將蓋子鎖 定在閉合狀態之機構。 另外，在上述方式之電氣連接器中，不論平形柔軟電纜 是否插入到插入空間，蓋子在閉合狀態下皆可滑動。因此， 當為使平形柔軟電纜插入到插入空間而開啟蓋子時，必需 在使蓋子開啟之同時注意使蓋子不會滑動到鎖定位置。因 此，平形柔軟電纜之安裝困難為其問題。隨著近年來之電 子機器（行動電話，數位視頻攝影機，類比視頻攝影機等） 之小型化，最好使電氣連接器小型化和薄型化，但是在小 型（薄型）之電氣連接器中，會使上述之問題特別顯著。 本發明係針對此種背景所完成，其目的係提供可以以更 簡單之構成將蓋子鎖定在閉合狀態之電氣連接器。 另外，本發明之另一目的是提供容易安裝平形柔軟電纜 之電氣連接器。 【發明内容】 本發明係關於電氣連接器（1，1 0 1 )，其被組裝在電路板 (8 )，用來將平形柔軟電纜（7 )電氣連接在上述電路板。該 電氣連接器具有：外殼（2 )，係具有用來插入上述平形柔軟 電纜之開口部（2 6 );及多個連接部（5，6 )，係被保持在上述 外殼，壓接在從上述開口部插入之上述平形柔軟電纜，用 6 312/發明說明書(補件)/93-06/93108834 1229476 來對該平形柔軟電纜電氣連接；及蓋子（4 )，係可以相 動地安裝在上述外殼上，用來使上述開口部開閉；及 部（5 7 2 )，係用來將該蓋子鎖定成為不會從閉合狀態轉 為開啟狀態。上述蓋子具有與上述多個連接部面對之 部（4 5 )，藉由從閉合狀態轉動成為開啟狀態，利用上 受部將上述多個連接部往壓接方向之相反方向舉起， 形成用來插入上述平形柔軟電纜之插入空間（2 7 )。另 上述鎖定部係被設在上述多個連接部中之至少一個之 部（5 )，在上述蓋子沿著電纜插入方向（D)滑動到指定 定位置之狀態，與上述接受部接合用來限制該接受部 另外，括弧内之英數字表示後面所述之實施形態之 構成元件等，但是本發明無意被解釋成只限於該實施 態。以下和在此項中相同。 依據本發明，在多個連接部中之至少1個之連接部 鎖定部，藉由使蓋子滑動，鎖定部和蓋子之接受部接 用來限制接受部，可以將蓋子鎖定在閉合狀態，因此 以以更簡單之構成將蓋子鎖定在閉合狀態。 上述多個連接部（5，6 )中之至少1個之連接部（5 )最 設有阻擋部（5 7 1 )，係可在上述插入空間（2 7 )未插入有 平形柔軟電纜（7 )之情況下，限制伴隨上述蓋子（4 )之 鎖定方向（電纜插入方向）之滑動時產生之上述接受部 之變位；另外一方面，在上述插入空間插入有上述平 軟電纜，使上述蓋子閉合之情況下，藉由上述多個連 在上述壓接方向之相反方向，被舉起與上述平形柔軟 312/發明說明書(補件)/93-06/93108834 對轉 鎖定 動成 接受 述接 可以 外， 連接 之鎖 〇 對應 形 設置 合， ，可 好更 上述 朝向 (45) 形柔 接部 電纜 7 1229476 之厚度對應之指定量，用來藉以使上述蓋子可以從上述接 受部退避在鎖定方向滑動。 依據此種構，成，在平形柔軟電纜未插入到插入空間之狀 態，因為蓋子被阻擋部限制成不能依鎖定方向滑動，所以 可將蓋子維持在可開閉狀態。因此，在將平形柔軟電纜插 入到插入空間之情況時，因為僅使蓋子開啟就可以形成插 入空間，所以平形柔軟電纜之安裝變為容易。 又，在平形柔軟電纟覽未插入到插入空間之狀態，因為不 能使蓋子在鎖定方向滑動，所以不能將該蓋子鎖定。但是， 在此狀態下，藉由接受部被限制在與接受部面對之多個連 接部上，將蓋子維持在閉合狀態。因此，因為可以防止蓋 子容易進行開閉，所以在該電氣連接器之製造時或搬運中 等，可以防止蓋子開啟而破損。 上述鎖定部（5 7 2 )和上述阻擋部（5 7 1 )，係亦可具備於在 上述多個連接部中之至少1個之連接部（5 )上所設有之突 出部（5 7 )上。 在此情況，最好使上述接受部（4 5 )，在上述插入空間（2 7 ) 未插入有上述平形柔軟電纜（7 )之情況下，伴隨上述蓋子（4 ) 之朝向鎖定方向之滑動，被上述突出部（5 7 )之上述阻擋部 (5 7 1 )限制；另一方面，在上述插入空間插入有上述平形柔 軟電纜之情況時，伴隨上述蓋子之朝向鎖定方向之滑動， 進入到在上述突出部和上述平形柔軟電纜之間所形成之空 間（4 6 )内，成為被上述突出部之上述鎖定部（5 7 2 )限制。 最好使上述蓋子（4 )設有接合部（4 3，4 7 )，係可對應該蓋 8 312/發明說明書(補件)/93-06/93108834 1229476 子在閉合狀態下在鎖定方向之滑動，而接合在上述電氣連 接器（1，1 0 1 )之指定位置（3 6，3 7 )，用來限制該蓋子朝向開 啟狀態之轉動。藉由此種構成，利用蓋子和電氣連接器之 指定位置之接合，可以更確實地將蓋子鎖定在閉合狀態。 本發明之電氣連接器最好更包含有補強翼片（3 )，係被 壓入至上述外殼（2 )，用來補強上述電氣連接器（1，1 0 1 )對 上述電路板（8 )之結合。在此情況，上述接合部（4 3，4 7 )亦 可以接合在上述補強翼片，用來限制上述蓋子（4 )之朝向開 啟狀態之轉動。 補強翼片，係例如使其電路板側之端面接觸在電路板， 藉由在該接觸部進行焊接，該接觸部的周圍被焊料所覆 蓋，以補強電氣連接器對電路板之固定。如此，利用對電 路板之固定被之補強翼片和接合部之接合，成為限制蓋子 朝向開啟狀態之變位之構成，藉此可以限制接合部使其穩 定，可以更確實的防止蓋子之開啟。 本發明之電氣連接器最好更包含有滑動限制部（4 8 )，係 用來限制上述蓋子（4 )從上述鎖定位置在鎖定解除方向（電 規插入方向之相反方向）進行滑動。 依據此種構成，藉由滑動限制部之限制，可形成若不以 手動使蓋子變位時，則不能使其在鎖定解除方向滑動之構 成。因此，在該電氣連接器之使用中等，可以防止由於振 動等使蓋子意外地在鎖定解除方向滑動，造成蓋子之開啟 而使平形柔軟電纜脫落。 另外，在鎖定位置不只可以鎖定蓋子之開閉，而且藉由 9 312/發明說明書(補件)/93-06/93108834 1229476 滑動限制部可以限制蓋子之滑動，所以可以更容易辨識電 纜之裝著完成。 本發明之電氣連接器亦可以更包含有補強翼片（3 )，係 被壓入至上述外殼（2 )，用來補強上述電氣連接器（1 0 1 )之 對上述電路板（8 )之結合。在此情況，上述滑動限制部（4 8 ) 最好藉由上述蓋子（4 )和上述補強翼片之接合以限制上述 蓋子之滑動。藉由此構成，利用對電路板之固定被補強之 補強翼片和滑動限制部之接合，因為可以限制蓋子之變位 使其穩定，所以可以更確實的防止蓋子之開啟。 上述鎖定部（5 7 2 )亦可以被設定在上述多個連接部（5，6 ) 中之指定之第1連接部（5 )。在此情況下，上述電氣連接器 最好更包含有鎖定位置限制部（6 6 1 )，具備在與上述多個連 接部中之上述第1連接部不同之第2連接部（6)上，在上述 插入空間（2 7 )插入有平形柔軟電纜（7 )之狀態，用來限制依 鎖定方向滑動之上述蓋子（4)，使其滑動不會超過上述鎖定 位置。 另外，亦可使上述第1連接部（5 )在上述蓋子（4 )之鎖定 方向被壓入到上述外殼（2 );上述第2連接部（6 )在上述蓋 子之鎖定解除方向，被壓入到上述外殼。 在此情況，最好形成第1連接部（5 )和第2連接部（6 )沿 著一方向（與電纜插入方向正交之方向）交替配置，且第1 連接部之對電路板（8 )之第1固定部（5 4 )和第2連接部之電 路板之第2固定部（6 4 )沿著上述一方向排列成為交錯狀之 構成。藉由此種構成，即使在第1連接部和第2連接部之 10 312/發明說明書(補件)/93-06/93108834 1229476 間隔（p i t c h )狹窄之情況時，亦可以確保具有充分之空間用 來將各個固定部焊接在電路板上。因此，可以防止形成在 各個固定部之周圍之焊料互相干涉而發生短路，同時，亦 可提高組裝密度。 本發明中，上述及其他目的之特徵和效果，藉由參照附 圖之下述對實施形態之說明，可更加明白。 【實施方式】 圖1係表示本發明之一實施形態之電氣連接器1外觀構 造之示意圖，圖1(a)是平面圖，圖1(b)是前視圖，圖1(c) 是後視圖，圖1 ( d )是右側視圖。但是，在圖1 ( a )〜（c )中， 將省略電氣連接器1之左右方向之中間部之圖示。 該電氣連接器1係例如使用在行動電話，數位視頻攝影 機，類比視頻攝影機等之較小型電子機器之連接器，左右 方向之長度為13mm程度，前後方向之長度為大約5mm程 度，高度為1 mm程度。電氣連接器1具備合成樹脂製之外 殼2，係具有例如由上板部21，下板部2 2和左右側板部 23區晝而成之内部空間24。該電氣連接器1係用來電氣連 接組裝有該電氣連接器1之電路板，和從外殼2之前方沿 著插入方向D插入到内部空間24之FPC(FlexiblePrinted Circuit)等之平形柔軟電纜。 在外殼2之左右側板部2 3，分別形成有從前端延伸到後 方之壓入孔25，在各個壓入孔25，從前方壓入有補強翼片 3，係用來補強該電氣連接器1之對電路板之固定。各個補 強翼片3係由例如經由對金屬板沖切加工和折曲加工而製 11 312/發明說明書(補件)/93-06/93108834 1229476 成，具有：壓入部31，係被壓入至壓入孔2 5 ;及主體部 3 2，係在安裝狀態下從外殼2之側板部2 3突出至前方。 主體部3 2之下緣構成對電路板之固定部3 3，藉由對該 固定部3 3和電路板之接觸部進行焊接，在該固定部3 3之 全周被焊料覆蓋以補強電氣連接器1對電路板之固定。另 外，在壓入部3 1之下端緣例如形成有繫止突起部3 4，係 用來使從前方壓入到壓入孔25之壓入部31，繫止在該壓 入孔2 5。 外殼2係例如其上板部2 1之前後方向之長度為下板部 22之前後方向之長度之大約一半之形成，藉此，外殼2之 上側之前半（被1對之補強翼片3在主體部3 2包夾之部份） 構成使平形柔軟電纜插入至内部空間2 4之開口部2 6，此 開口部2 6係；藉由可以以沿著左右方向同軸延伸之金屬製 之轉動軸4 1為中心進行轉動之合成樹脂製之蓋子4進行開 閉。在蓋子4内，例如埋設有用來補強該蓋子4之金屬板 42 ° 各個轉動軸4 1，係從蓋子4之左右兩端面之後端部朝向 左右方向突出，藉由此等之轉動軸41插入到形成在對應之 補強翼片3之主體部3 2之上部係側之導引孔3 5，蓋子4 可相對於補強翼片3轉動地被安裝導引孔3 5係在前後方向 延伸，在後方開放之缺口部，旋轉軸41係沿著導引孔3 5 之方式，使蓋子4可以在前後方向滑動。 在蓋子4之左右兩端面之前後方向中央部之下部，係例 如接合部4 3突出形成。另外，在各個補強翼片3之主體部 12 312/發明說明書(補件)/93-06/93108834 1229476 3 2之上部之前端部，例如，形成突出部3 6，在開口部2 6 側折曲成為突出近似梯形狀（例如〇 . 1 5 m m程度，在使蓋子 4開啟，經由開口部2 6將平形柔軟電纜插入到外殼2内之 後，使蓋子4閉合，在並使其滑動到後方之情況下，蓋子 4之各個接合部4 3在對應之補強翼片3之突出部3 6之下 方進行滑動。然後，在使蓋子4滑動到最後側之狀態，例 如平面視下，接合部4 3在其前後方向之長度（例如，〇 · 4丨η m 程度）全體，成為與突出部36上下重疊。 依據此種構成，在使蓋子4滑動到最後側之狀態，因為 該接合部4 3被各個補強翼片3之突出部3 6從上方限制， 所以可以確實地防止蓋子4之開啟。特別是，補強翼片3 因為經由焊接被強固地固定在電路板，所以可以穩定地限 制蓋子4之接合部4 3，而確實地防止蓋子4之開啟。 但是，例如在使蓋子4和補強翼片3之一方形成之凸 部，和形成在另外一方之凹部接合之構造中，亦可以限制 蓋子4之開啟。 另外，蓋子4之接合部4 3並不只限於接合在補強翼片3 者，亦可以為接合在電氣連接器1之其他之部份（例如，外 殼2 )之構成。 在外殼2中，設有用來壓接在被插入至插入空間2 7之 平形柔軟電纜，以達成該平形柔軟電纜與電路板之電氣連 接之多個連接部5，6 (例如合計3 5個）以面臨開口部2 6的 方式被保持著。各個連接部5，6係由例如金屬板之沖切加 工製成。該多個連接部5，6，例如在平面視下，係在左右 13 312/發明說明書(補件)/93-06/93108834 1229476 方向隔開等間隔（例如Ο . 3 ui m間距程度）（參照圖1 ( a ))平行 地被配置。 在本實施形態中，在多個連接部5，6係例如包含有從前 方壓入到外殼2之第1連接部5，及從後方壓入到外殼2 之第2連接部6二種，此等第1和第2連接部5，6在沿著 左右方向交替地被配置。 但是，第1連接部5和第2連接部6對於外殼2之壓入 方向並不只限於上述之方向，亦可以為第1連接部5從後 方壓入至外殼2，而將第2連接部6從前方壓入到外殼2 之構成。另外，亦可以為將第1連接部5及第2連接部6 從相同之方向（前方或後方）壓入之構成。 圖2及圖3係沿著圖1 ( c )之A _ A線之剖面圖。另，圖4 及圖5係沿著圖1 ( c )之B - B線之剖面圖。 參照圖2〜圖5，各個連接部（圖2，3所示之第1連接部 5和圖4，5所示之第2連接部6 )，係其前端部（可動片部 53, 63之前端部）突出到外殼2之上板部21之前方（蓋子4 側）。在蓋子4之後端緣，在對應於各個連接部5，6之前端 部之位置，形成有用來防止蓋子4在開閉時與各個連接部 5, 6之前端部互相干涉之凹槽44。 在凹槽4 4内，係例如形成有具有剖面近似橢圖形狀之 凸輪形狀之接受部4 5，在使蓋子4閉合之狀態，接受部4 5 成為使其橢圖剖面之長軸在前後方向延伸。在不將平形柔 軟電纜7插入至外殼2内，使蓋子4閉合之狀態（圖2 (a) 和圖4 ( a ))下，各個連接部5，6之前端部之下面，非接觸 14 312/發明說明書(補件)/93-06/93108834 1229476 地面對對應之接受部4 5之上面，在此狀態下，成為 接部5, 6上無應力之作用。另外，接受部4 5之形狀 限於剖面近似橢圓形狀者，亦可為具有其他之凸輪？ 從圖2 ( a )和圖4 ( a )所示之狀態開啟蓋子4時，4 接部5 , 6被進行旋轉之接受部4 5舉起，在連接部5 接位置形成高度等於或大於平形柔軟電纜7之厚度 空間2 7 (參照圖2 ( b )及圖4 ( b ))。經由該插入空間 以使平形柔軟電纜7插入到連接部5，6之内方。此 連接器1可以使平形柔軟電纜7在無插入力下插入 謂之 ZIF (Zero Insertion Force)型者。 以下，參照圖2和圖3，說明關於伴隨蓋子4之 平形柔軟電纜7之插入，第1連接部5之動作態樣。 表示未插入平形柔軟電纜7，使蓋子4閉合之狀態， 表示從圖2 ( a )之狀態使蓋子4開啟之狀態。另外， 表示在蓋子4開啟之狀態插入平形柔軟電纜7之狀 3 ( b )表示從圖3 ( a )之狀態使蓋子4閉合之狀態，圖 表示使蓋子4滑動到後方之狀態。 第1連接部5係例如具備有：固定片部5 1，係在 之内部空間24之底部之前後方向延伸；彈性變形名 係從該固定片部5 1之後端部突出至上方，成為彎曲 側之形狀；及可動片部5 3，係被連設在彈性變形部 並延伸到上板部2 1之前方。在固定片部5 1之前端 成有突出到下方（電路板8側）之引線部5 4，藉由在 部5 4，及電路板8之組裝面上之焊接區之接觸部上 312/發明說明書(補件)/93-06/93108834 各個連 並不只 衫狀者。 善由連 ，6之壓 之插入 27，可 種電氣 ，即所 開閉及 圖 2(a) 圖 2(b) 圖 3(a) 態，圖 3(c) 外殼2 P 52， 向前方 52上， 部，形 該引線 進行焊 15 1229476 接，該接觸部之周圍被焊料所覆蓋。藉此，使第1連接部 5被固定在電路板8，並使該第1連接部5電氣連接到電路 板8 〇 另外，在固定片部51之係端部，形成有突出至後方之 壓入部55，藉由壓入部55從前方壓入到形成在外殼2之 壓入孔2 8内，第1連接部5被固定在外殼2上。在壓入部 5 5之上端緣，例如形成有繫止突起部5 5 1，係使從前方壓 入到壓入孔28之壓入部55繫止在該壓入孔28。 從可動片部5 3之中央部，例如，壓接在插入至插入空 間2 7之平形柔軟電纜7上（所謂上接點型之）之連接部5 6 向下方突出。另外，在固定片部51之中央部，於比面對連 接部5 6之位置稍微靠前之位置，形成有突出到上方之加壓 部5 1 1。另外，在可動片部5 3之前端部（接受部4 5之後 側），係有在未插入平形柔軟電纜之情況（圖2 ( a )之狀態） 下，以蓋子4不能向後方滑動之方式來限制接受部4 5之阻 擋部57，向下方突出形成。 如圖2 ( a)所示，在不將平形柔軟電纜7插入到外殼2 内，使蓋子4閉合之狀態，即使蓋子4滑動到後方，因為 沿著接觸面5 8滑動之接受部4 5被阻擋部5 7之前面（滑動 限制面5 7 1 )限制，所以不能滑動到更後方。當從圖2 ( a ) 所示之狀態使蓋子4開啟時，伴隨蓋子4之轉動，接受部 4 5進行旋轉（參照圖2 ( b ))。因為接受部4 5具有剖面近似 橢圖之凸輪形狀，所以伴隨接受部4 5之旋轉，使可動片 部5 3之前端部被舉起。藉此，在可動片部5 3和固定片部 16 312/發明說明書(補件)/93-06/93108834 1229476 5 1之間（連接部5 6和加壓部5 1 1之間）形成高度等於或大 於平型柔軟電纜7之厚度之插入空間2 7。 如圖2 ( b )所示，在蓋子4最開啟之狀態，因為接受部 45之剖面長度方向（橢圖剖面之長軸方向）和可動片部53 之前端部之下面（接觸面58)略成為正交，所以從受作用力 向下方之可動片部53之接觸面施加在接受部45之力，不 在該接受部4 5之旋轉方向（使蓋子4閉合之方向）發生作 用。因此，在使蓋子4最開啟時，維持圖2 ( b)所示之狀態。 然後，如圖3 ( a )所示，從電氣連接器1之前方將平形柔 軟電纜7插入至該插入空間2 7，當使蓋子4轉動到前方 時，藉由作用於可動片部53之作用力，從接觸面58向使 接受部4 5旋轉之方向施力，用來使蓋子4成為閉合狀態（參 照圖3 (b))。在此狀態，可動片部5 3之接觸部5 6之前端 從上方壓接在平形柔軟電纜7。在此同時，因為加壓部5 1 1 在壓接位置略靠前之位置，將平形柔軟電纜7加壓至上 方，所以平形柔軟電纜7被牢固地被包夾在第1連接部5， 用來達成此等之間之電氣連接。 在圖3 ( b )所示之狀態，因為接觸部5 6被壓接在平形柔 軟電纜7上，所以成為可動片部5 3被舉起平形柔軟電纜7 之厚度部份之狀態。藉此，在阻擋部5 7和平形柔軟電纜7 之上面之間，形成可以使接受部4 5通過之充分高度之空間 4 6，當從圖3 ( b)所示之狀態，使蓋子4滑動到後方時，接 受部4 5成為位於形成在阻擋部5 7之下方之空間4 6内之狀 態（參照圖3 ( c ))。 17 312/發明說明書(補件)/93-06/93108834 1229476 在圖3 ( c)所示之狀態，即使欲使蓋子4開啟時，因為蓋 子4之後端緣接觸在平形柔軟電纜7之上面，接收部4 5 之上面接觸在阻擋部5 7之下面（轉動限制面5 7 2 )，所以不 能使接受部4 5旋轉，而不能使蓋子4開啟。 依據本實施例，因為在第1連接部5設置阻擋部5 7，藉 由使蓋子4滑動，將阻擋部5 7和蓋子4之接受部4 5接合， 用來限制接受部4 5之旋轉，可以將蓋子4鎖定在閉合狀 態。因此，可以以更簡單之構成將蓋子4鎖定在閉合狀態。 另外，在平形柔軟電纜7未被插入至外殼2内之狀態（圖 2 ( a )及（b )之狀態），因為接受部4 5受到阻擋部5 7之限制， 使蓋子4不能滑動到後方，所以可維持蓋子4之開閉狀態。 因此，在將平形柔軟電纜7插入到外殼2内之情況下，因 為只需要使蓋子4開啟就可以形成插入空間2 7，所以可以 容易地安裝平形柔軟電纜7。 在平形柔軟電纜7未被插入至插入空間2 7之狀態，因 為不能使蓋子4滑動，所以不能鎖定該蓋子4。但是，在 此狀態，因為該接受部4 5被限制在與接受部4 5面對之多 個連接部5，6，所以蓋子4被維持在閉合狀態。因此，由 於可以防止蓋子4太易於開閉，所以可以防止在該電氣連 接器1之製造時或搬運中等由於蓋子4之意外開啟而破損。 在本實施形態中，係說明關於滑動限制面5 7 1及轉動限 制面5 7 2具備於同一構件上（阻擋部5 7 )之構成，但也可 為分別具備於不同構件上之構成。 其次，參照圖4及圖5，說明伴隨蓋子4之開閉和平形 18 312/發明說明書(補件)/93-06/93108834 1229476 柔軟電纜7之插入，第2連接部6之動作態樣。圖4 (a)表 示未插入平形柔軟電纜7，使蓋子4閉合之狀態，圖4 (b) 表示從圖4 ( a )之狀態使蓋子4開啟之狀態。另，圖5 ( a ) 表示在蓋子4開啟之狀態下，插入平形柔軟電纜7之狀態， 圖5 ( b )表示從圖5 ( a )之狀態使蓋子4閉合之狀態，圖5 ( c )

4，用來將壓入部6 5壓入至外殼2， 以將第2連接部6固定在外殼2。在壓入部6 5之下端緣， 例如形成有繫止突起部6 5 1，係用來使從後方壓入到内部 空間2 4之第2連接部6之壓入部6 5，繫止在外殼2之内 面〇 在壓入部65之後端下部，形成有突出至下方（電路板8 側）之引線部6 4，在該引線部6 4及電路板8之組裝面上之 焊接區之接觸部，藉由進行焊接該接觸部之周圍被焊料所 覆蓋。藉此，第2接觸部6被固定在電路板8上，用來使 該第2連接部6對電路板8電氣連接。 在本實施形態中，因為第1連接部5之引線部5 4從外 殼2之前端部突出至下方，第2連接部6之引線部6 4從外 19 312/發明說明書(補件)/93-06/93108834 1229476 殼2之後端部突出，所以在從下方看該電氣 況下，各個連接部5, 6之引線部5 4, 6 4沿著 成為交錯狀（參照圖1 ( b )和c )。藉此，即使 5和第2連接部6之間隔（pitch)為狹窄之情 以確保充分之空間用來將各個引線部5 4，6 4 8，所以可以防止形成在各個引線部5 4，6 4之 相干涉而發生短路，並可以提高組裝密度。 可動片部6 3之前端部係成為例如近似L字 包含有：（所謂上接點型之）接觸部6 6，係大 延伸，從上方壓接在被插入至插入空間2 7之 7上；及接觸部6 7，從接觸部6 6之上端突出

a)所示，從電氣連接器1之前方將平形柔 軟電纜7插入至插入空間2 7，當使蓋子4轉動至前方時， 藉由作用於對可動片部6 3之作用力，從接觸面6 8向使接 受部4 5旋轉之方向施力，用來使蓋子4成為閉合狀態（參 照圖5 ( b))。在此狀態，可動片部6 3之接觸部6 6之前端 從上方壓接在平形柔軟電纜7上。在此同時，因為加壓部 6 1 1在壓接位置之略靠前位置，將平形柔軟電纜7加壓至 上方，所以平形柔軟電纜7牢固地被包夾在第2連接部6， 以達成此等之間電氣連接。 在從圖5 ( b )所示之狀態使蓋子4滑動到後方時（參照圖 5(c))，接受部4 5接觸在接觸部6 6之前面（滑動限制面 6 6 1)，可以使蓋子4不會更進一步的滑動到後方。此時， 在第1連接部5，阻擋部5 7成為位於接受部4 5之上面。 另外一方面，在拆下連接在該電氣連接器1之平形柔軟 電纜7之情況下，利用與上述之態樣相反之態樣使蓋子4 變位即可。亦即，使蓋子4變位至前方，在使蓋子4成為 可開閉之狀態之後，使蓋子4開啟藉由將第1和第2連接 部5，6舉起，用來解除各個連接部5，6對平形柔軟電纜7 之壓接，將平形柔軟電纜7向前抽出時，即可以將平形柔 軟電纜7從電氣連接器1拆下。 圖6係顯示本發明之另一實施形態之電氣連接器1 0 1之 21

F型。該電氣連接器1 0 1與第 1實施形態之電氣連接器1不同之處係只在於蓋子4及補 助翼片3之接合位置之構成，因此，關於其他之構成，在 圖中附加相同之符號，而省略其說明。 在蓋子4之左右兩端面之下部，例如形成有從中央部至 前端，突出至側方之接合部4 7。另，在各個補強翼片3之 主體部3 2之上部之前端部，例如形成有折曲之突出部3 7， 係在開口部2 6側突出成為近似V字狀（例如，0 . 1 3mm程 度）。在蓋子4開啟，經由開口部2 6將平形柔軟電纜7插 入至外殼2内之後，使蓋子4閉合，壓入至後方（插入方向 D )時，蓋子4之各個接合部4 7係滑動至對應之補強翼片3 之突出部3 7下方。然後，在將蓋子4壓入到最後側（鎖定 位置）之狀態，例如在平面視下，接合部4 7之後端部（例如 0.3mm程度）成為與突出部37上下重疊。 依據此種構成，在將蓋子4壓入到最後側之狀態，因為 該接合部4 7被各個補強翼片3之突出部3 7限制，所以可 以確實地防止蓋子4被開啟。特別是，補強翼片3因為經 由焊接被強固地固定在電路板8，所以可以穩定地限制蓋 22 312/發明說明書(補件)/93-06/93108834 1229476 子4之接合部4 7，可以更確實的防止蓋子4之開啟。 在蓋子4之左右兩端面之前後方向中央部之上部，例如 形成有在平面視下近似三角形狀之限制部4 8，突出至側 方。如圖6及圖7所示，在蓋子4位於最近前側之狀態， 限制部4 8成為接觸在補強翼片3之突出部3 7之近前側之 面之狀態。當從此狀態將蓋子4壓入到後方時，藉由限制 部4 8，突出部3 7被按壓至外側，使補強翼片3彈性變形。 然後，當更進一步將蓋子4壓入至後方時，限制部4 8跨越 突出部3 7移動至突出部3 7之後方側。在此狀態，補強翼 片3回到原來之狀態，突出部3 7被擋住在限制部4 8，朝 向蓋子4之近前側（解除鎖定方向）之滑動受到限制，所以 若不對蓋子4施加外力使其變位時，不會使其滑動到近前 側。 該電氣連接器1 0 1，係第1實施形態之電氣連接器1同 樣地，當蓋子4位於最近前側時，可以使蓋子4開啟，但 是當蓋子4位於最深側（鎖定位置）時，不能使蓋子4開啟。 如上述，在將蓋子4壓入到最深側之狀態，若不對蓋子4 施加外力使其變位時，不能使其滑動到近前側。因此，在 該電氣連接器1 0 1在使用中等，可以防止由於振動使蓋子 4意外的滑動到近前側，使蓋子4開啟而造成平形柔軟電 纜7之脫落。 特別是因為藉由與被強固地固定在電路板8之補強翼片 之接合，可以穩定地限制蓋子4滑動到近前側，所以可以 更確實的防止蓋子4之開啟。 23 312/發明說明書(補件)/93-06/93108834 1229476 另外，因為不只在鎖定位置可以鎖定蓋子4之開閉，而 且藉由限制部4 8可以限制蓋子4之滑動，所以可以提高電 繞裝著操作之完成感。 但是，其構成並不只限於藉由從蓋子4突出之接合部4 7 及補強翼片3之突出部3 7之接合，用來限制蓋子4之開 啟，或藉由從蓋子4突出之限制部48及補強翼片3之突出 部3 7之接合，用來限制蓋子4之滑動之構成，例如，亦可 以為藉由形成在蓋子4和補強翼片3中之一方之凸部及形 成在另外一方之凹部之接合，用來限制蓋子4之開閉或滑 動之構成。 另外，蓋子4之接合部4 7或限制部4 8並不只限於接合 在補強翼片3者，亦可以為接合在電氣連接器1之其他部 份（例如，外殼2 )之構成。 本發明並不只限定於以上之實施形態之内容，亦可為在 申請專利範圍之範圍内進行之各種變更。 例如，在插入空間2 7未插入有平形柔軟電纜7之狀態用以P方止 蓋子4滑動之阻擋部5 7 ;及藉由該阻擋部5 7和蓋子4之接受部

electrical connector for connecting a flat flexible cable such as FPC (Flexible Printed Circuit) to a circuit board. [Prior art] A conventional electrical connector is provided with a housing having an opening portion for inserting a flat flexible cable, and the flat flexible cable inserted from the opening is crimped by a plurality of connection portions held in the housing, Used to achieve electrical connection to the flat flexible cable. In this type of electrical connector, there is a cover that can be installed in the housing in a relatively rotatable manner by turning to open. At the crimping position of a plurality of connecting portions, an insertion space can be inserted into a flat flexible cable, so that it can be inserted without force Insert the flat flexible cable into this insertion space. This type of electrical connector is a so-called ZIF (Zero Insertion Force) type. When the flat flexible cable is inserted and the cover is closed, a plurality of connecting portions are crimped to the flat flexible cable to achieve electrical connection. In such an electrical connector, for example, when the lid is closed, the lid is subjected to a force in the closing direction, making it difficult to open the lid. However, when the electrical connector is subjected to external force (vibration, etc.) during manufacture, during transportation and use, it may cause the cover to open, the flat flexible cable mounted to it to fall off, or the cover may be damaged. Therefore, there has been proposed an electrical connector (refer to, for example, Japanese Patent Laid-Open Nos. 2 0 2-2 5 2 0 6 7), and the lid is slid to the designated lock position by sliding the lid in the closed state to engage the lid. It can be locked in the closed position by engaging in the specified position of the electrical connector 5 312 / Invention Specification (Supplement) / 93-06 / 93108834 1229476 (for example, a metal reinforcing tab). However, in the above-mentioned electrical connector, it is necessary to provide parts for the locking mechanism near the opening where the cover is installed, or to extend the reinforcing fins. Therefore, it is desirable to form a mechanism capable of locking the lid in a closed state with a simpler structure. In addition, in the electrical connector of the above-mentioned method, the lid can be slid in the closed state regardless of whether the flat flexible cable is inserted into the insertion space. Therefore, when the cover is opened in order to insert the flat flexible cable into the insertion space, care must be taken so that the cover does not slide to the locked position while the cover is opened. Therefore, the difficulty in installing flat flexible cables is a problem. With the miniaturization of electronic devices (mobile phones, digital video cameras, analog video cameras, etc.) in recent years, it is desirable to reduce the size and thickness of electrical connectors. However, in small (thin) electrical connectors, The above problems are particularly significant. The present invention has been made in view of such a background, and an object thereof is to provide an electrical connector that can lock a cover in a closed state with a simpler structure. In addition, another object of the present invention is to provide an electrical connector for easily mounting a flat flexible cable. SUMMARY OF THE INVENTION The present invention relates to an electrical connector (1, 101) which is assembled on a circuit board (8) for electrically connecting a flat flexible cable (7) to the circuit board. The electrical connector has: a housing (2) having an opening (2 6) for inserting the flat flexible cable; and a plurality of connection parts (5, 6) held in the housing and crimped in The flat flexible cable inserted into the opening is electrically connected to the flat flexible cable using 6 312 / Invention Specification (Supplement) / 93-06 / 93108834 1229476; and the cover (4) can be installed in the above-mentioned manner in a phase-shifting manner. The housing is used to open and close the opening portion; and the portion (5 7 2) is used to lock the cover so as not to change from the closed state to the open state. The cover has a portion (4 5) facing the plurality of connecting portions, and is turned from a closed state to an open state. The upper receiving portion lifts the plurality of connecting portions in a direction opposite to the crimping direction, and is used for forming. Insert the insertion space (2 7) of the flat flexible cable. In addition, the locking portion is provided in at least one of the plurality of connecting portions (5), and the cover is slid to a predetermined position along the cable insertion direction (D), and is engaged with the receiving portion to restrict In addition, the alphanumeric characters in the parentheses indicate constituent elements and the like of the embodiment described later, but the present invention is not intended to be interpreted as being limited to the embodiment. The following are the same as in this item. According to the present invention, the sliding portion of at least one of the plurality of connecting portions locks the receiving portion by restricting the receiving portion by sliding the cover. The locking portion can be locked in the closed state. With a simpler structure, the lid is locked in a closed state. At least one of the plurality of connection portions (5, 6) is provided with a blocking portion (5 7 1), and a flat flexible cable (7) can be inserted into the insertion space (2 7). ), Restrict the displacement of the receiving part caused by sliding in the locking direction (cable insertion direction) of the cover (4); on the other hand, insert the flat flexible cable into the insertion space to make the cover In the case of being closed, the above-mentioned flat flexible 312 / Invention Manual (Supplement) / 93-06 / 93108834 can be lifted to accept the connection by the above-mentioned multiple connected in the opposite direction of the crimping direction. In addition, the connecting lock 〇 correspondingly fits, and can be changed to a specified amount corresponding to the thickness of the above-mentioned (45) -shaped flexible joint cable 7 1229476, so that the cover can be retracted from the receiving portion and slide in the locking direction. . According to this configuration, in a state where the flat flexible cable is not inserted into the insertion space, the lid is restricted by the blocking portion so that it cannot slide in the locking direction, so the lid can be maintained in an openable and closable state. Therefore, when the flat flexible cable is inserted into the insertion space, since the insertion space can be formed only by opening the cover, the installation of the flat flexible cable becomes easy. In addition, in a state where the flat-shaped flexible electric view is not inserted into the insertion space, the lid cannot be slid in the locking direction, so the lid cannot be locked. However, in this state, the lid is kept closed because the receiving portion is restricted to a plurality of connecting portions facing the receiving portion. Therefore, since the lid can be prevented from being easily opened and closed, the lid can be prevented from being opened and damaged during the manufacture or transportation of the electrical connector. The locking portion (5 7 2) and the blocking portion (5 7 1) may be provided with a protruding portion (5 7) provided on at least one of the connecting portions (5) of the plurality of connecting portions. )on. In this case, it is preferable that the receiving portion (4 5) slides in the locking direction with the cover (4) when the flat flexible cable (7) is not inserted in the insertion space (2 7). Restricted by the blocking portion (5 7 1) of the protruding portion (5 7); on the other hand, when the flat flexible cable is inserted in the insertion space, the cover slides in the locking direction and enters the A space (4 6) formed between the protruding portion and the flat flexible cable is restricted by the locking portion (5 7 2) of the protruding portion. Preferably, the cover (4) is provided with a joint (4 3, 4 7), which can correspond to the cover 8 312 / Invention Specification (Supplement) / 93-06 / 93108834 1229476 in the locked state in the locked direction. Slide and engage in the specified position (36, 37) of the electrical connector (1, 1 0 1) to limit the rotation of the cover toward the open state. With this structure, the lid can be locked in the closed state more securely by engaging the lid with the specified position of the electrical connector. The electrical connector of the present invention preferably further includes a reinforcing fin (3), which is pressed into the casing (2) to reinforce the electrical connector (1, 101) to the circuit board (8). Combination. In this case, the joint portion (4, 3, 7) may also be joined to the reinforcing fin to restrict the rotation of the cover (4) toward the open state. The reinforcing fin is, for example, the end surface on the circuit board side is brought into contact with the circuit board, and the contact portion is soldered, and the periphery of the contact portion is covered with solder to reinforce the fixing of the electrical connector to the circuit board. In this way, the joining of the reinforcing fins and the joints to the circuit board is used to restrict the displacement of the lid toward the open state, so that the joints can be restricted and stabilized, and the lid can be more reliably prevented from being opened. The electrical connector of the present invention preferably further includes a slide restricting portion (48) for restricting the cover (4) from sliding from the locked position in the unlocking direction (the direction opposite to the insertion direction of the electric gauge). According to this configuration, it is possible to form a structure in which the lid cannot be slid in the unlocking direction unless the lid is manually displaced by the restriction of the slide restricting portion. Therefore, in the use of this electrical connector, it is possible to prevent the cover from being accidentally slid in the unlocking direction due to vibration and the like, which can cause the cover to open and the flat flexible cable to come off. In addition, in the locked position, not only the opening and closing of the cover can be locked, but also the sliding of the cover can be restricted by 9 312 / Invention Manual (Supplement) / 93-06 / 93108834 1229476, so it is easier to identify the completion of the cable installation. . The electrical connector of the present invention may further include a reinforcing fin (3), which is pressed into the housing (2) to reinforce the electrical connector (101) to the circuit board (8). Combined. In this case, it is preferable that the sliding restricting portion (4 8) restricts the sliding of the lid by engaging the lid (4) and the reinforcing fin. With this configuration, the joining of the reinforcing fins that are fixed to the circuit board and the sliding restriction portion can restrict the displacement of the lid and stabilize it, so that the lid can be more reliably prevented from being opened. The locking portion (5 7 2) may be set to a designated first connecting portion (5) among the plurality of connecting portions (5, 6). In this case, it is preferable that the electrical connector further includes a lock position restricting portion (6 6 1), which is provided on a second connection portion (6) different from the first connection portion of the plurality of connection portions. A state where a flat flexible cable (7) is inserted in the insertion space (2 7) is used to restrict the cover (4) sliding in the locking direction so that the sliding does not exceed the locked position. In addition, the first connecting portion (5) may be pressed into the housing (2) in the locking direction of the cover (4); the second connecting portion (6) may be pressed in the unlocking direction of the cover. Into the enclosure. In this case, it is preferable to form the first connection portion (5) and the second connection portion (6) alternately arranged in one direction (direction orthogonal to the cable insertion direction), and the first connection portion is opposite to the circuit board (8). ), The first fixing portion (5 4) and the second connection portion (6 4) of the circuit board of the second connection portion are arranged in a staggered pattern along the above-mentioned direction. With this configuration, even when the pitch of the first connection part and the second connection part is 10 312 / Invention Specification (Supplement) / 93-06 / 93108834 1229476 is narrow, a sufficient space can be ensured Used to solder the various fixing parts to the circuit board. Therefore, it is possible to prevent solders formed around the respective fixing portions from interfering with each other to cause a short circuit, and at the same time, it is possible to increase the assembly density. The features and effects of the above and other objects in the present invention will be made clearer by the following description of embodiments with reference to the accompanying drawings. [Embodiment] Fig. 1 is a schematic diagram showing an appearance structure of an electrical connector 1 according to an embodiment of the present invention. Fig. 1 (a) is a plan view, Fig. 1 (b) is a front view, and Fig. 1 (c) is a rear view. Figure 1 (d) is a right side view. However, in FIGS. 1 (a) to (c), the illustration of the middle portion in the left-right direction of the electrical connector 1 will be omitted. The electrical connector 1 is a connector for smaller electronic devices such as mobile phones, digital video cameras, and analog video cameras. The length in the left-right direction is about 13 mm, the length in the front-back direction is about 5 mm, and the height is 1 mm. degree. The electrical connector 1 includes a casing 2 made of synthetic resin, and has an internal space 24 formed by, for example, an upper plate portion 21, a lower plate portion 22, and left and right side plate portions 23. The electrical connector 1 is used to electrically connect a circuit board on which the electrical connector 1 is assembled, and a flat flexible cable such as an FPC (Flexible Printed Circuit) inserted into the internal space 24 from the front side of the housing 2 in the insertion direction D. Pressing holes 25 extending from the front end to the rear are formed in the left and right side plate portions 23 of the housing 2, respectively. Reinforcing fins 3 are press-fitted from the front in each pressing-in hole 25 to reinforce the electrical connector 1 It is fixed to the circuit board. Each of the reinforcing fins 3 is made of, for example, a punching process and a bending process of a metal plate 11 312 / Invention Specification (Supplement) / 93-06 / 93108834 1229476, and has a press-in portion 31, which is pressed into The press-in holes 25 and the main body portion 32 protrude from the side plate portion 23 of the housing 2 to the front in the installed state. The lower edge of the main body portion 32 constitutes a fixing portion 33 for the circuit board. By soldering the contact portion between the fixing portion 33 and the circuit board, the entire periphery of the fixing portion 33 is covered with solder to reinforce the electrical connection. Device 1 fixes the circuit board. In addition, a lower end edge of the press-fitting portion 31 is formed with, for example, a stop projection 34 for press-fitting the press-fitting portion 31 from the front into the press-fitting hole 25 to be stopped at the press-fitting hole 25. The outer casing 2 is formed, for example, by a length in the front-rear direction of the upper plate portion 21 which is about half of the length in the front-rear direction of the lower plate portion 22. Thus, the upper half of the upper side of the outer casing 2 (reinforced by a pair of fins 3 in the The main body part 3 2 is a part of the package) constituting an opening 2 6 for inserting a flat flexible cable into the internal space 2 4, and this opening part 2 6 is a metal rotating shaft that can extend coaxially in the left-right direction. A cover 4 made of synthetic resin, which is rotated around the center 1 is opened and closed. In the cover 4, for example, a metal plate 42 for reinforcing the cover 4 is embedded. Each of the rotation shafts 41 is protruded from the left and right end surfaces of the cover 4 toward the left and right directions, and the rotation shaft 41 is inserted into the cover. A guide hole 3 5 is formed on the upper part side of the main body part 3 2 of the corresponding reinforcing fin 3, and the cover 4 is rotatably installed with respect to the reinforcing fin 3. The guide hole 3 5 extends in the front-rear direction and rear In the opened notch portion, the rotation shaft 41 follows the guide hole 3 5 so that the cover 4 can slide in the front-rear direction. The lower part of the central part in the front-rear direction of the left and right end faces of the lid 4 is formed by protruding parts such as the joint part 43. In addition, in the main body portion 12 312 / Invention Manual (Supplement) / 93-06 / 93108834 1229476 3 2 of each of the reinforcing fins 3, the front end portion is formed, for example, a protruding portion 36 is formed, and the opening portion 2 6 is folded at the side The curve becomes a prominent approximate ladder shape (for example 〇. About 15 mm, after opening the cover 4 and inserting the flat flexible cable into the housing 2 through the opening portion 26, the cover 4 is closed, and each of the joint portions 4 of the cover 4 is slid to the rear 3 Slide below the corresponding protrusions 36 of the corresponding reinforcing fins 3. Then, in a state where the cover 4 is slid to the rearmost side, for example, the entire length of the joint portion 43 in the front-rear direction (for example, about 0.4 mm) is overlapped with the protrusion portion 36 in a plan view. According to this configuration, in a state where the lid 4 is slid to the rearmost side, the engaging portion 43 is restricted from above by the protruding portions 36 of the reinforcing fins 3, so that the lid 4 can be reliably prevented from being opened. In particular, since the reinforcing fin 3 is firmly fixed to the circuit board by soldering, the joint portion 4 3 of the lid 4 can be stably restricted, and the lid 4 can be reliably prevented from being opened. However, for example, in a structure in which a convex portion formed on one of the lid 4 and the reinforcing fin 3 is joined to a concave portion formed on the other side, the opening of the lid 4 may be restricted. In addition, the joint portion 43 of the cover 4 is not limited to those joined to the reinforcing fins 3, and may also be constituted by being joined to other parts of the electrical connector 1 (for example, the housing 2). The housing 2 is provided with a plurality of connection portions 5, 6 (for example, a total of 3 to 5) for crimping the flat flexible cable inserted into the insertion space 27 to achieve the electrical connection between the flat flexible cable and the circuit board. It is held so as to face the opening portion 26. Each of the connecting portions 5, 6 is made of, for example, a punching process of a metal plate. The plurality of connecting portions 5, 6 are spaced at equal intervals (for example, 0) in the direction of left and right 13 312 / Invention Specification (Supplement) / 93-06 / 93108834 1229476, for example, in a plan view. 3 ui m pitch degree) (see Fig. 1 (a)) are arranged in parallel. In this embodiment, the plurality of connection portions 5, 6 include, for example, a first connection portion 5 which is pressed into the housing 2 from the front, and a second connection portion 6 which is pressed into the housing 2 from the rear. The first and second connection portions 5 and 6 are alternately arranged in the left-right direction. However, the direction in which the first connection portion 5 and the second connection portion 6 are pressed into the housing 2 is not limited to the above-mentioned direction. The first connection portion 5 may be pressed into the housing 2 from behind, and the second connection portion 6 may be pressed in. The structure is pushed into the housing 2 from the front. Alternatively, the first connection portion 5 and the second connection portion 6 may be pressed in from the same direction (front or rear). 2 and 3 are cross-sectional views taken along line A_A in FIG. 1 (c). 4 and 5 are cross-sectional views taken along line B-B in FIG. 1 (c). Referring to FIGS. 2 to 5, each connecting portion (the first connecting portion 5 shown in FIGS. 2 and 3 and the second connecting portion 6 shown in FIGS. 4 and 5) is a front end portion (a movable piece portion 53, 63 The front end portion) protrudes in front of the plate portion 21 above the casing 2 (the cover 4 side). A recess 44 is formed at the rear end edge of the cover 4 to prevent the cover 4 from interfering with the front end of each connection portion 5, 6 at the position corresponding to the front end portion of each connection portion 5, 6. In the groove 4 4, for example, a receiving portion 45 having a cam shape having a cross-sectional approximate oval shape is formed. When the cover 4 is closed, the receiving portion 4 5 has the major axis of the oval cross section in the front-rear direction. extend. In the state where the flat flexible cable 7 is not inserted into the housing 2 and the cover 4 is closed (Fig. 2 (a) and Fig. 4 (a)), the lower end of the front end of each connection portion 5, 6 is non-contact 14 312 / Invention Specification (Supplement) / 93-06 / 93108834 1229476 The surface faces the upper surface of the corresponding receiving portion 45. In this state, it becomes a stress-free effect on the connecting portions 5, 6. In addition, the shape of the receiving portion 45 is limited to those having an approximately elliptical cross section, and may have other cams? When the cover 4 is opened from the state shown in FIG. 2 (a) and FIG. 4 (a), the 4 connecting parts 5 and 6 are lifted by the rotating receiving part 4 5 to form a height equal to or greater than the flat shape at the connecting part 5 The thickness space 2 7 of the flexible cable 7 (refer to FIG. 2 (b) and FIG. 4 (b)). Through the insertion space, the flat flexible cable 7 is inserted into the connection portions 5 and 6. This connector 1 allows a flat flexible cable 7 to be inserted without a insertion force, so-called ZIF (Zero Insertion Force) type. The operation of the first connection portion 5 with respect to the insertion of the flat flexible cable 7 with the cover 4 will be described below with reference to Figs. 2 and 3. The state in which the flat flexible cable 7 is not inserted and the cover 4 is closed is shown, and the state in which the cover 4 is opened from the state of FIG. 2 (a) is shown. In addition, the state where the flat flexible cable 7 is inserted when the cover 4 is opened 3 (b) shows a state where the cover 4 is closed from the state shown in FIG. 3 (a), and the figure shows a state where the cover 4 is slid to the rear. The first connecting portion 5 includes, for example, a fixing piece portion 51 that extends forward and backward from the bottom of the internal space 24; and an elastic deformation name protrudes upward from a rear end portion of the fixing piece portion 51 to become a curved side. And the movable piece portion 53 are connected to the elastic deformation portion and extend to the front of the upper plate portion 21. A lead portion 5 4 is formed at the front end of the fixed piece portion 51 to protrude downward (on the side of the circuit board 8). Instruction (Supplement) / 93-06 / 93108834 Each company is not just shirt-shaped. Good cause, the pressure of 6 is inserted into 27, which can be kind of electrical, that is, the state of opening and closing and Fig. 2 (a), Fig. 2 (b), Fig. 3 (a), Fig. 3 (c), housing 2 P 52, forward 52 , The shape of the lead is to be soldered 15 1229476, and the contact area is covered by solder. Thereby, the first connection portion 5 is fixed to the circuit board 8, and the first connection portion 5 is electrically connected to the circuit board 8. In addition, a pressure protruding to the rear is formed at the end portion of the fixing piece portion 51. The push-in portion 55 is pushed into the push-in hole 28 formed in the case 2 from the front by the press-fit portion 55, and the first connection portion 5 is fixed to the case 2. At the upper edge of the press-fitting portion 55, for example, a stop protrusion 5 51 is formed to stop the press-fitting portion 55 pressed into the press-fitting hole 28 from the front. From the central portion of the movable piece portion 53, for example, a connection portion 5 6 crimped to a flat flexible cable 7 (so-called upper contact type) inserted into the insertion space 27 is protruded downward. In addition, in the central portion of the fixed piece portion 51, a pressing portion 5 1 1 is formed to be slightly forward from a position facing the connecting portion 56. In addition, at the front end portion of the movable piece portion 53 (rear side of the receiving portion 45), there is a case where the flat flexible cable is not inserted (the state of FIG. 2 (a)), so that the cover 4 cannot slide backward. The blocking portion 57 to restrict the receiving portion 45 is formed to protrude downward. As shown in Fig. 2 (a), when the flat flexible cable 7 is not inserted into the casing 2 and the cover 4 is closed, even if the cover 4 slides to the rear, the receiving portion 4 5 is slid along the contact surface 5 8 The blocking portion 5 7 is restricted by the front surface (sliding restriction surface 5 7 1), so it cannot slide to the rear. When the lid 4 is opened from the state shown in FIG. 2 (a), the receiving portion 45 is rotated with the rotation of the lid 4 (see FIG. 2 (b)). Since the receiving portion 45 has a cam shape with an approximately elliptical cross-section, the front end portion of the movable piece portion 5 3 is lifted with the rotation of the receiving portion 45. Thereby, a height is formed between the movable piece portion 5 3 and the fixed piece portion 16 312 / Invention Specification (Supplement) / 93-06 / 93108834 1229476 5 1 (between the connection portion 5 6 and the pressurizing portion 5 1 1). The insertion space 2 7 is equal to or greater than the thickness of the flat flexible cable 7. As shown in FIG. 2 (b), in the state where the cover 4 is most opened, the length of the cross section of the receiving portion 45 (the direction of the long axis of the ellipsoidal section) and the underside of the front end portion of the movable piece portion 53 (contact surface 58) are slightly omitted. Since it is orthogonal, the force applied to the receiving portion 45 from the receiving surface to the contact surface of the movable piece portion 53 below does not act in the direction of rotation of the receiving portion 45 (the direction in which the lid 4 is closed). Therefore, when the lid 4 is most opened, the state shown in FIG. 2 (b) is maintained. Then, as shown in FIG. 3 (a), the flat flexible cable 7 is inserted into the insertion space 2 7 from the front of the electrical connector 1, and when the cover 4 is turned forward, it acts on the movable piece portion 53. The force is applied from the contact surface 58 in a direction to rotate the receiving portion 45 to bring the lid 4 into a closed state (see FIG. 3 (b)). In this state, the front end of the contact portion 5 6 of the movable piece portion 53 is crimped to the flat flexible cable 7 from above. At the same time, since the pressing portion 5 1 1 is slightly forward of the crimping position and presses the flat flexible cable 7 upward, the flat flexible cable 7 is firmly sandwiched between the first connecting portion 5 and To achieve these electrical connections. In the state shown in FIG. 3 (b), since the contact portion 56 is crimped to the flat flexible cable 7, the movable piece portion 53 is lifted up to the thickness portion of the flat flexible cable 7. Thereby, a space 4 6 is formed between the blocking portion 5 7 and the upper surface of the flexible flexible cable 7 at a sufficient height to allow the receiving portion 4 5 to pass. When the cover 4 is slid from the state shown in FIG. 3 (b) At the rear, the receiving portion 45 is placed in a space 46 formed below the blocking portion 57 (see FIG. 3 (c)). 17 312 / Invention Specification (Supplement) / 93-06 / 93108834 1229476 In the state shown in Figure 3 (c), even when the cover 4 is to be opened, the rear edge of the cover 4 contacts the flat flexible cable 7, The upper portion of the receiving portion 45 is in contact with the lower portion of the blocking portion 5 7 (the rotation restricting surface 5 7 2), so the receiving portion 4 5 cannot be rotated, and the lid 4 cannot be opened. According to this embodiment, since the blocking portion 57 is provided in the first connecting portion 5, the blocking portion 5 7 and the receiving portion 45 of the cover 4 are engaged by sliding the cover 4 to restrict the rotation of the receiving portion 45. The lid 4 can be locked in a closed state. Therefore, the cover 4 can be locked in the closed state with a simpler configuration. In addition, in a state where the flat flexible cable 7 is not inserted into the casing 2 (a state of FIGS. 2 (a) and (b)), the receiving portion 45 is restricted by the blocking portion 57, so that the cover 4 cannot slide to the rear Therefore, the opened and closed state of the cover 4 can be maintained. Therefore, in the case where the flat flexible cable 7 is inserted into the housing 2, since the insertion space 2 7 can be formed only by opening the cover 4, the flat flexible cable 7 can be easily installed. In the state where the flat flexible cable 7 is not inserted into the insertion space 27, the cover 4 cannot be slid, so the cover 4 cannot be locked. However, in this state, since the receiving portion 45 is restricted to a plurality of connecting portions 5, 6 facing the receiving portion 45, the lid 4 is maintained in a closed state. Therefore, since the lid 4 can be prevented from being opened and closed too easily, it can be prevented from being damaged due to the accidental opening of the lid 4 during the manufacture or transportation of the electrical connector 1. In the present embodiment, the configuration is described in which the slide restricting surface 5 71 and the rotation restricting surface 5 7 2 are provided on the same member (blocking portion 5 7), but may be separately provided on different members. Next, referring to FIG. 4 and FIG. 5, description will be given of the operation of the second connecting portion 6 with the insertion of the flexible cable 7 with the opening and closing of the cover 4 and the flat shape 18 312 / Invention Specification (Supplement) / 93-06 / 93108834 1229476. Fig. 4 (a) shows a state where the flat flexible cable 7 is not inserted and the cover 4 is closed, and Fig. 4 (b) shows a state where the cover 4 is opened from the state of Fig. 4 (a). In addition, Fig. 5 (a) shows a state where the flat flexible cable 7 is inserted with the lid 4 opened, and Fig. 5 (b) shows a state where the lid 4 is closed from the state shown in Fig. 5 (a), and Fig. 5 (c) Shows the state where the cover 4 is slid behind. The second connecting portion 6 includes, for example, an approximately rectangular press-fitting portion 65, which is disposed behind the inner space 24 of the housing 2 and has a height substantially the same as the height of the inner space 24. The fixed piece portion 61 is formed from the pressing portion. The front end of the lower portion of the entry portion 65 extends to the front along the bottom of the internal space 24; and the movable piece portion 63 is extended from the front end of the upper portion of the press-in portion 65 to the front of the upper plate portion 21 via the elastic deformation portion 62. square. The second connection portion 6 is inserted into the inner space 2 4 of the casing 2 from the rear to press the press-in portion 65 into the casing 2 to fix the second connection portion 6 to the casing 2. A lower edge of the press-fitting portion 65 is formed with, for example, a retaining protrusion 6 5 1 for pressing the second connection portion 6 of the second connection portion 6 from the rear into the inner space 2 4, and is secured to the housing 2. On the inner surface, at the lower end of the press-fit portion 65, a lead portion 64 protruding to the lower side (the circuit board 8 side) is formed, and the contact portion of the soldering area of the lead portion 64 and the assembly surface of the circuit board 8 is formed by The periphery of the contact portion is covered with solder by soldering. Thereby, the second contact portion 6 is fixed to the circuit board 8 for electrically connecting the second connection portion 6 to the circuit board 8. In this embodiment, since the lead portion 54 of the first connection portion 5 protrudes from the front end portion of the housing 2 to the lower side, the lead portion 64 of the second connection portion 6 is from the outside 19 312 / Invention Specification (Supplement) / 93 -06/93108834 1229476 The rear end of the case 2 protrudes, so when looking at the electrical condition from below, the lead portions 5 4, 6 4 of each connection portion 5, 6 are staggered along the edges (see Fig. 1 (b) and c ). Thereby, even if the pitch between 5 and the second connection portion 6 is narrow to ensure a sufficient space for using the respective lead portions 5 4, 6 4 8, it is possible to prevent the lead portions 5 4, 6 from being formed. The interference of 4 causes short circuit, which can improve the assembly density. The front end portion of the movable piece portion 63 becomes, for example, an approximately L-shape, and includes: (a so-called upper contact type) a contact portion 66 which extends greatly and is crimped from above into the insertion space 2 7-7; And the contact portion 67, the protruding surface from the upper end of the contact portion 66 constitutes a contact surface 68 contacting the receiving portion 45. In addition, a pressing portion 6 11 is formed at the front end portion 4 and is located slightly forward from the contact position and protrudes upward. As shown in Fig. 4 (a), the flat flexible electric gauge 7 is not inserted. When the lid 4 is opened from the closed state of the lid 4, the receiving part 45 is rotated (see Fig. 4 (b)). Since it has a cam shape with an approximately elliptical cross section, the front end portion of the movable piece portion 63 is lifted with the receiving name. Thereby, the insertion space between the movable fixed piece portion 61 (the contact portion 66 and the pressing portion 6 1 1 or more than the thickness of the flat flexible cable 7 is shown in FIG. 4 (b), and the cover 4 In the most opened state, the length direction of the section (long axis direction of the elliptical section) and the lower end of the movable end (contact surface 68) are slightly orthogonal. Therefore, '312 / Invention Specification (Supplement) / 93-06 / 93108834 In the case of connector 1, the left and right directions are arranged in the first connection portion, because the solder can be soldered around the circuit board, so that the flat flexible cable in the up and down direction to the front, the lower t fixed piece 61 The part 66 faces into the housing 2, and as the lid 4 rotates, the receiving part 45 rotates the furnace 45, and the sheet part 63 and the solid part 21 form a height 21. Receiving part 4 5 previously moved from receiving force 20 1229476 downward contact surface 68 of movable part 63 exerted a force on receiving part 45, not in the direction of rotation of receiving part 4 5 (close lid 4 (Direction), so when the lid 4 is most opened, the state shown in FIG. 4 (b) is maintained. Then, as shown in FIG. 5 (a), the flat flexible cable 7 is inserted into the insertion space 2 7 from the front of the electrical connector 1, and when the cover 4 is rotated to the front, it acts on the movable piece portion 63. The urging force is applied from the contact surface 68 to a direction in which the receiving portion 45 is rotated, so that the lid 4 is closed (see FIG. 5 (b)). In this state, the front end of the contact portion 6 6 of the movable piece portion 63 is crimped to the flat flexible cable 7 from above. At the same time, since the pressing portion 6 1 1 is slightly forward of the crimping position and presses the flat flexible cable 7 upward, the flat flexible cable 7 is firmly sandwiched by the second connecting portion 6 to achieve These are electrically connected. When the cover 4 is slid to the rear from the state shown in FIG. 5 (b) (refer to FIG. 5 (c)), the receiving portion 45 contacts the front surface of the contact portion 6 6 (the sliding restriction surface 6 6 1), so that The cover 4 does not slide further to the rear. At this time, in the first connection portion 5, the blocking portion 57 is positioned above the receiving portion 45. On the other hand, when the flat flexible cable 7 connected to the electrical connector 1 is detached, the cover 4 may be displaced by using a shape opposite to that described above. That is, the cover 4 is moved forward, and after the cover 4 is opened and closed, the cover 4 is opened, and the first and second connecting portions 5 and 6 are lifted to release the respective connecting portions 5, When 6 pairs of flat flexible cables 7 are crimped, the flat flexible cables 7 can be removed from the electrical connector 1 when the flat flexible cables 7 are pulled out forward. FIG. 6 is a perspective view showing an appearance structure of an electrical connector 1 0 1 of 21 312 / Invention Specification (Supplement) / 93-06 / 93108834 1229476 according to another embodiment of the present invention. Fig. 7 is a plan view of the electrical connector 101. However, as shown in Fig. 7, the middle part in the left-right direction of the electrical connector 101 is omitted. The electrical connector 101 is, for example, similar to the electrical connector 1 of the first embodiment, and is used to electrically connect a flat flexible cable 7 such as an FPC to the circuit board 8. The flat flexible cable 7 can be inserted without force. Next, it is inserted into the insertion space 27 and becomes a so-called ZIF type. This electrical connector 101 differs from the electrical connector 1 of the first embodiment only in the configuration of the joint position of the cover 4 and the auxiliary wing 3, and therefore, the same symbols are added to the drawings for other configurations. , And its description is omitted. At the lower portions of the left and right end surfaces of the lid 4, for example, there are formed joint portions 47 that protrude from the central portion to the front end to the side. In addition, at the front end portion of the upper portion of the main body portion 3 2 of each of the reinforcing fins 3, for example, a bent protruding portion 37 is formed to protrude into an approximately V shape (for example, 0. 1 3mm degree). After the cover 4 is opened and the flat flexible cable 7 is inserted into the housing 2 through the openings 26, the cover 4 is closed and pushed into the rear (insertion direction D), and each joint portion 4 7 of the cover 4 slides to correspond Below the protruding part 3 7 of the reinforcing fin 3. Then, in a state where the cover 4 is pushed to the rearmost side (locked position), for example, in plan view, the rear end portion (eg, 0. (Approximately 3 mm) overlaps with the protrusion 37. According to this configuration, in the state where the cover 4 is pushed to the rearmost side, the engaging portion 47 is restricted by the protruding portions 37 of the reinforcing fins 3, so that the cover 4 can be reliably prevented from being opened. In particular, since the reinforcing fin 3 is firmly fixed to the circuit board 8 by soldering, the cover 22 312 / Invention Manual (Supplement) / 93-06 / 93108834 1229476 Sub-joint 4 7 can be stably More securely prevents the lid 4 from being opened. On the upper portion of the central portion in the front-rear direction of the left and right end surfaces of the cover 4, for example, a restricting portion 48 formed in a substantially triangular shape in plan view is formed to project to the side. As shown in Figs. 6 and 7, in a state where the cover 4 is located on the nearest front side, the restricting portion 48 is in a state of contacting the surface on the front side of the protruding portion 37 of the reinforcing fin 3. When the cover 4 is pushed into the rear from this state, the protruding portion 37 is pressed to the outside by the restricting portion 48, and the reinforcing fin 3 is elastically deformed. Then, when the cover 4 is pushed back further, the restricting portion 48 moves across the protruding portion 37 to the side behind the protruding portion 37. In this state, the reinforcing flap 3 returns to the original state, the protruding portion 37 is blocked by the restricting portion 48, and the sliding toward the front side (unlocking direction) of the cover 4 is restricted. Therefore, if no external force is applied to the cover 4, When it is displaced, it does not slide to the near side. This electrical connector 101 is the electrical connector 1 of the first embodiment. Similarly, when the cover 4 is located on the nearest front side, the cover 4 can be opened. However, when the cover 4 is located on the deepest side (locked position), it cannot be opened. The lid 4 is opened. As described above, when the cover 4 is pushed into the deepest side, it cannot be slid to the near side when the cover 4 is not displaced by applying an external force. Therefore, in the use of the electrical connector 101, it is possible to prevent the cover 4 from being accidentally slid to the front side due to vibration, and the cover 4 is opened to cause the flat flexible cable 7 to fall off. In particular, since the cover 4 can be stably restricted from sliding to the near side by being engaged with the reinforcing fins which are firmly fixed to the circuit board 8, the cover 4 can be prevented from being opened more reliably. 23 312 / Invention Manual (Supplement) / 93-06 / 93108834 1229476 In addition, the lid 4 can be locked and closed not only in the locked position, but also the lid 4 can be restricted from sliding by the restricting portion 48, so the electrical winding can be improved. The sense of completion of the operation. However, the configuration is not limited to the engagement of the engaging portion 4 7 protruding from the cover 4 and the protruding portion 37 of the reinforcing fin 3 to restrict the opening of the cover 4 or the restricting portion 48 protruding from the cover 4. The engagement with the protruding portion 37 of the reinforcing fin 3 is used to restrict the sliding of the cover 4. For example, it may be a convex portion formed on one of the cover 4 and the reinforcing fin 3 and formed on the other side. The engagement of the recesses is used to restrict the opening and closing or sliding of the lid 4. In addition, the joint portion 47 or the restricting portion 48 of the cover 4 is not limited to those joined to the reinforcing fins 3, and may be constituted by being joined to other parts of the electrical connector 1 (for example, the housing 2). The present invention is not limited to the contents of the above embodiments, and may be various changes made within the scope of the patent application. For example, in a state where the flat flexible cable 7 is not inserted in the insertion space 2 7, the blocking portion 5 7 that prevents the lid 4 from sliding; and the engagement of the blocking portion 5 7 and the receiving portion 45 of the lid 4 is locked. The locking mechanism for opening the position prevention cover 4 is not limited to the configuration provided in the first connection portion 5, and may also be a configuration in which at least one of the blocking portion and the locking mechanism is provided with the second connection portion. In addition, all of the plurality of connection portions may have the same configuration as the first connection portion 5. The first connection portion 5 and the second connection portion 6 are not limited to those that are crimped on the flat flexible cable 7 from above, and can also be flat on the flat flexible cable 312 / Invention Manual (Supplement) / 93-06 / 93108834 24 1229476 The cable 7 is crimped and becomes the so-called lower contact type. In the above embodiment, FPC is used as an example of the flat flexible cable 7. However, the electrical connector 1,101 of the present invention can also be applied to the installation of other flat flexible cables such as FFC (Flexible Flat Cable). So far, the embodiments of the present invention have been described in detail, but these are only specific examples for clearly explaining the technical content of the present invention. The present invention should not be construed as being limited to these specific examples, and the spirit and scope of the present invention are limited only by Limited by the scope of the attached patent application.
