，具有以連結部連結的上腕部與下腕部的橫η字型的鎖定 配件（鎖定構件），該鎖定配件的上腕部，朝較連結部更 靠近扁平型導體的***側的後方，水平延伸，在其後部形 成有爪狀的鎖定部（卡合部）。該鎖定部，朝向扁平型導 體側’作成朝下方突出的大致倒三角形，當連接器使用時 ’當可動構件（滑塊）朝用來將扁平型導體朝端子的接觸 部按壓的關閉位置移動時，上述鎖定配件的上腕部，在其 前部被可動構件的凸輪部抬起，利用槓桿原理，讓上腕部 的後部朝下方傾斜，於是，鎖定部朝下方移位。結果，讓 上述鎖定部從上方朝向：***於上腕部與下腕部之間的扁 平型導體的形成爲缺口部或孔部的被卡止部，與該被卡止 部的前緣卡止，防止扁平型導體不經意脫落。 -5- 201203739 [先前技術文獻] [專利文獻] [專利文獻1] 日本特開2004-221067 【發明內容】 [發明欲解決的課題] 專利文獻1的連接器，爲了防止扁平型導體不經意脫 落，卡止於該扁平型導體的被卡止部的只有鎖定配件的鎖 定部，並且，該鎖定部相對於扁平型導體的面從上方，也 就是從其中一側卡止於上述被卡止部。可是，上述鎖定部 是作成大致倒三角形。於是，雖然扁平型導體與端子的接 觸部具有預定的接觸壓力而處於正式的連接狀態，而當將 扁平型導體強力地朝拔出方向拉時，扁平型導體的被卡止 部，將拔出方向的力帶到上述大致倒三角形的鎖定部的前 部斜緣》該力量，在前部斜緣產生朝上方的分力，結果， 將鎖定配件的上腕部的後部朝上方回復，減少了該後部也 就是鎖定部的移位的量》也就是說，會產生：鎖定部與被 卡止部的卡止量減少、或脫落這樣的不經意的扁平型導體 脫落的情形。 本發明鑑於這種情形，在使用鎖定配件的電路基板用 電連接器，其課題是要提供一種電路基板用電連接器，在 扁平型導體的正式的連接狀態下，即使不經意有較強力量 作用於扁平型導體的拔出方向，鎖定部與被卡止部的卡止 -6- 201203739 量也能隨時保持得很大，或者藉由補強該被卡止部讓卡止 狀態不會改變’而能確實達成防止脫落。 [用以解決課題的手段] 本發明的電路基板用電連接器，是配置於電路基板上 ，將所***的扁平型導體與電路基板電連接的電連接器， 是具有： 設置有：維持金屬板的平坦的板面所作成而與扁平型 導體接觸的接觸部、與電路基板連接的連接部、按壓扁平 型導體的按壓部、以及用來承受使該按壓部朝按壓方向移 位的力的被壓部，在與上述板面成直角的方向排列的複數 的端子； 設置有：與端子同樣地維持金屬板的平坦的板面所作 成而與扁平型導體卡止而鎖定的鎖定部、以及用來承受使 該鎖定部移位的力的被壓部，配置成板面與上述端子平行 的鎖定配件； 形成有用來將***的扁平型導體的連接部分予以收容 的收容空間，在上述接觸部與扁平型導體接觸的位置保持 上述端子，且保持鎖定配件的殼體； 以及設置有用來將力量施加到上述端子及鎖定配件的 被壓部的加壓部，能夠於：可***扁平型導體的開啓位置 、與將扁平型導體朝端子的接觸部按壓，並且將鎖定部帶 到鎖定位置的關閉位置之間移動的可動構件； 上述端子及鎖定配件，藉由將以扁平型導體的***方 201203739 向作爲長軸方向延伸的上腕部與下腕部，在其長軸方向中 間位置藉由連結部連結所形成，端子，其上腕部在較連結 部更靠近扁平型導體的***方向前側的前部具有被壓部， 在後部具有按壓部，鎖定配件其上腕部在前部具有被壓部 ，在後部具有突起狀的鎖定部。 在電路基板用電連接器，在本發明，殼體或保持於殼 體的構件，具有：相對於扁平型導體***用的載置面形成 爲較高的突部，鎖定部與突部是對於扁平型導體從上下進 行作用。 在這種構造的本發明，當扁平型導體在載置面上*** 至預定位置時，該扁平型導體的被卡止部，相對於藉由殼 體或殼體所保持的構件所形成的突部，在前方位置，在上 下方向也就是扁平型導體的厚度方向，具有與該突部的重 複範圍，當拔出方向的力作用於扁平型導體時，成爲卡止 於該突部的位置關係（前者的位置關係）、或是成爲被卡 止部的周邊位於突部上，扁平型導體在該部分朝上方彎曲 的位置關係（後者的位置關係）。 前者的位置關係的情況，相對於扁平型導體的被卡止 部，鎖定配件的鎖定部從上方卡止，在端子排列方向在與 該鎖定部不同的位置，讓在殼體或殼體所保持的構件形成 的突部，從下方卡止。 相對於上述被卡止部，由於鎖定部與突部從上下卡止 ，所以扁平型導體在上下的任何方向都維持卡止。並且， 扁平型導體在端子的按壓部被向下方按壓，所以與殻體的 -8- 201203739 卡止部的卡止在充裕的範圍，即使朝扁平型導體的力伴隨 朝上方的分力，將扁平型導體抬起，也藉由來自上述按壓 部的力且藉由鎖定配件的鎖定部加以卡止。 接著，在後者的位置關係的情況，由於扁平型導體的 被卡止部的周邊位於突部上，所以在抬起被卡止部的位置 ，在前後方向並未與突部卡止。可是，藉由該抬起’加深 了被卡止部與上述鎖定部的卡合。於是，即使扁平型導體 被朝上方抬起，當然也藉由來自上述按壓部的力卡止於鎖 定部，即使朝下方偏移，藉由來自上述突部的抬起力’則 不會加大該偏移而確保與鎖定部的卡止》 在本發明，突部可作成：可在前後方向與扁平型導體 的被卡止部卡止，且設置成位於該扁平型導體的下面側的 卡止突起。在該情況，扁平型導體的被卡止部，會在上下 方向與該卡止突起具有重複範圍，結果，成爲在前後方向 卡止的位置。 在本發明，鎖定配件的鎖定部與殻體的卡止突起，其 位置是在用來伸入：在扁平型導體的側緣形成爲被卡止部 的缺口凹部。 在本發明，殼體的卡止突起，其位置在：在上下方向 在較端子的接觸部更下方處。 扁平型導體雖然***成配置於端子的接觸部上，而此 時，殼體的卡止突起，是位在較接觸部更下方，所以不會 成爲扁平型導體要進行插拔時的障礙。且另一方面，當連 接器使用時，藉由讓可動構件來到關閉位置，將扁平型導 -9- 201203739 體朝下方按壓，讓扁平型導體的被卡止部確實地來到可與 殼體的卡止突起卡止的位置，所以藉由讓突部位於較接觸 部更下方，則不會有卡止偏移的情形。 在本發明，殻體，在端子排列方向的兩端部，具有： 對於扁平型導體進行在上下方向及端子排列方向的限制的 限制部，該限制部，具有：在前後方向朝較端子的後端更 後方延伸的延伸部。 藉由作成這樣方式，則當扁平型導體***時，在該扁 平型導體與端子的接觸部相接之前，以限制部決定在上下 方向及端子排列方向的位置，所以在上述方向，扁平型導 體不會有多餘動作，能在預定的位置進行順暢的***，不 會損傷到接觸部。 並且，在本發明，端子，其下腕部在前後方向在與該 按壓部對應的位置，具有接觸部。藉由將按壓部與接觸部 在前後方向配置在對應位置，則在接觸部與扁平型導體的 接觸能更確實且穩定。 在本發明，突部，在端子排列方向在與鎖定配件不同 的位置，較高地形成至：當可動構件位於關閉位置時，較 鎖定配件的鎖定部的下端部更上方的位置。藉此，鎖定部 與突部，其與扁平型導體的被卡止部的卡止量變大。 [發明效果] 如上述，在本發明，殻體或殼體所保持的構件，在端 子排列方向在與鎖定配件不同的位置，具有突部，該突部 -10- 201203739 相對於用來***扁平型導體的載置面較高地形成至：當可 動構件在關閉位置時，較鎖定配件的鎖定部的下端部更上 方的位置，所以當扁平型導體在載置面上***至預定位置 時，該扁平型導體的被卡止部，相對於藉由殼體或殼體所 保持的構件所形成的突部，在前方位置在上下方向也就是 在扁平型導體的厚度方向，與該突部共同作用，所以當拔 出方向的力作用於扁平型導體時，成爲卡止於該突部的位 置關係、或成爲被卡止部的周邊位於突部上，扁平型導體 在該部分朝上方彎曲的位置關係，前者的位置關係的情況 ，扁平型導體即使在上下偏移的狀態，在拔出方向受到不 經意的較強力量，鎖定部與突部的其中一方成爲較弱卡止 的狀態，另一方也會成爲較強的卡止狀態，所以在兩者的 共同作用下，能隨時充裕地卡止，確實地防止扁平型導體 脫落。並且，扁平型導體在端子的按壓部被向下方按壓， 所以形成鎖定部的鎖定配件的上腕部，也會阻止產生像： 扁平型導體的被卡止部從殼體的突部脫落並且從鎖定配件 的鎖定部脫落這樣過大的移位，所以上述來自上下的鎖定 部與卡止突起達成的卡止能穩定地確保。而且在後者的位 置關係的情況，扁平型導體的被卡止部的周邊位於突部上 ，所以雖然被卡止部在被抬起的位置，與突部在前後方向 並未卡止，而藉由該抬起，會加深被卡止部與上述鎖定部 的卡合。於是，即使將扁平型導體朝上方抬起，也當然藉 由來自上述按壓部的力量而卡止於鎖定部，即使朝下方偏 移，藉由來自上述突部的抬起力，不會加大該偏移，確保 -11 - 201203739 與鎖定部的卡止。 【實施方式】 以下根據附圖，來說明本發明的實施方式。 第1圖是顯示本實施方式的電路基板用電連接器（以 下「連接器」）的全體，以及該連接器連接的扁平型導體 的前端部的連接部分的立體圖。 扁平型導體F，在其前端部下面，將覆蓋部去除而導 體部（沒有圖示）露出，在上面將薄片狀的補強材F1安裝 成：較該導體部朝更前方朝向連接器1突出。該補強材F1 ，在較導體部更前方的左右的側緣形成有缺口狀的被卡止 部F2。 連接器1，是具有：由金屬板作成的端子10、20、鎖 定配件30、將上述構件予以保持的殼體40、以及可自由轉 動地支承於殼體40的可動構件60。 端子10、20、與鎖定配件30,都是維持金屬板的平坦 面所作成。端子由兩種端子1〇、2 0所構成，將其在與端子 10、20的板面成直角的方向排列成交互位置，與在同方向 位於兩端的端子10、20鄰接而設置鎖定配件30。 兩種端子10、20，如在該端子10、20的剖面圖也就是 第2圖（A ) 、（ B )所示，都作成橫Η型，具有：分別朝 橫方向延伸的上腕部11、21、下腕部12、22、以及將兩腕 部在其長軸方向中間部連結的連結部1 3 ' 2 3。上腕部1 1、 21，在作爲扇平型導體F的***方向的前方的前部’形成 -12- 201203739 有以後述的可動構件的凸輪部按壓的被壓部14、24，在後 部形成有從上方按壓扁平型導體的按壓部15、25。在下腕 部12、22的前部，形成有上述凸輪用的支承部16、26，而 在後部形成有用來與扁平型導體的導體部接觸用的接觸部 17、27。且在下腕部12、22，設置有：與電路基板焊接用 的連接部18、28。 以上，雖然針對兩種端子1 〇、20的共通點來敘述，接 著針對差異點來說明。 端子10的上腕部11，如第2圖（A)所示，在前部的下 緣處設置的被壓部1 4作成凹部，而從連結部1 3朝後方長長 地延伸而在其後端設置有突狀的按壓部1 5。相對的，端子 2 0的上腕部21，如第2圖（B)所示，在前部的下緣處設置 的被壓部24是以直狀緣部形成，且從連結部23朝後方延伸 的部分，較上述端子10的情況更短，在其後端設置有突狀 的按壓部25。 端子10的下腕部12，如第2圖（A)所示，從連結部13 朝前方延伸而在延伸到殼體40外的部分形成有連接部1 8 » 連接部18，具有朝下方凹入彎曲的溝狀的固定部18A。在 連結部1 3與連接部1 8之間的部‘分，形成有：上緣作成凹狀 用來收容凸輪部的支承部16。相對的，端子20的下腕部22 ，如第2圖（B )所示，在從連結部23朝前方延伸的部分的 上緣，作成大致直狀緣部形成了支承部26,朝後方延伸的 部分延伸到殼體40外，具有：與上述端子10的連接部18大 致前後對稱的形態的連接部28及固定部28A。該端子20的 -13- 201203739 下腕部22，在前後方向，在連結部23與連接部28的中間部 ，在與上腕部21的按壓部25對應的位置，設置有突狀的接 觸部27。 這樣形成的兩種端子1〇、20，如第1圖所示，將端子 10從前方且將端子20從後方朝殼體40安裝，將其交互排列 〇 鎖定配件30，如第2圖（C)及第3圖所示，作成與端 子20類似的橫Η字型，與端子20同樣地，具有上腕部31與 下腕部32，兩者在其長軸方向中間部藉由連結部33連結。 該鎖定配件30，在前部，上腕部31與下腕部32，都作成與 上述端子20相同的型態，在上腕部31的前部，以直狀緣部 形成有被壓部34，在下腕部32的前部形成有大致直狀緣部 的支承部36。該鎖定配件30的後部，有與上述端子20不同 之處。上腕部31的後部，其長度較端子20更長，在與端子 1 〇大致相同位置，形成有朝後方延伸的鎖定腕3 1 Α。在其 後端設置有：朝向下方的較大的突出狀的鎖定部35。上述 鎖定腕3 1 A，朝向後上方傾斜延伸。該鎖定腕3 1 A，當上 述被壓部34被後述關閉位置的可動構件的凸輪部按壓而朝 上方抬起移位時，因爲槓桿原理，以連結部3 3爲支點朝下 方移位，結果，變成來到大致水平位置。在該情況，鎖定 腕3 1 A即使不在完全水平的位置，或有些許的傾斜，只要 是實質上可稱爲水平姿勢的姿勢即可。例如，當可動構件 在開啓位置時具有傾斜的鎖定腕，當可動構件來到關閉位 置時，雖然其傾斜角度變小而變得接近水平位置，而仍然 -14- 201203739 有些許的傾斜，或是即使超過水平位置而在相反側產生些 許的傾斜，在其傾斜度很小的情況，都可說是實質上& # 平位置。在上述鎖定腕31A的後端處設置的突出狀的鎖定 部35，前緣35A作成大致垂直緣，後緣35B朝前下方傾斜。 該鎖定部35，在上腕部31在被壓部3 4沒有受到來自凸輪部 的力的狀態，當***扁平型導體F時，是成爲與該扁平型 導體F的前端緣干涉的在高度方向的位置關係。在上述下 腕部32的後端，設置有與端子2〇的連接部28相同型態的固 定腳38，在這裡形成有溝狀的固定部38 A ^ 將上述端子10、20及鎖定配件30予以保持的殻體40， 是由電絕緣材所作成，如第1圖所示，作成較平坦的大致 長方體外型，如第2圖，前後（在圖中的右方及左方）貫 穿而形成有：分別將端子10、20及鎖定配件30予以保持的 端子保持溝41、42及鎖定配件保持溝43。該端子保持溝41 、42及鎖定配件保持溝43，以將板狀的端子10、2 0及鎖定 配件30面對保持成讓與其板面保持些許間隙的方式，在第 2圖在與紙面成直角的方向形成爲與其板厚度相當的溝寬 度的狹縫。相對於端子保持溝41、42及鎖定配件保持溝43 ，端子10、20及鎖定配件30，藉由在其下緣形成的突起19 、2 9及突起39，卡止於溝底而在上下緣堅固地保持。該端 子保持溝41、42及鎖定配件保持溝43，在殼體4〇的前部與 朝向上方大幅缺口的前部空間44連通，並且在前後方向藉 由從中間位置朝向後方形成的扁平型導體F用的作爲收容 空間的***溝45所連通。藉由該***溝45的形成’殼體40 -15- 201203739 在其上下位置變得具有上壁46及下壁47，在該上壁46及下 壁47的面，端子保持溝41、42作成爲開口溝的型態。該上 壁46，在鎖定配件30的位置，讓該鎖定配件30的鎖定腕 3 1 A進入的溝部48上下貫穿而形成爲狹縫狀。下壁47相對 於端子1 〇，前端較薄地形成爲大致錐狀，作成讓端子1 〇的 溝狀的固定部18A嵌裝的保持部47A，相對於端子20及鎖 定配件30，作成在後端同樣形成的端子20及鎖定配件30的 各個固定部28A及38A用的保持部47A。在上述下壁47朝上 方開口的端子10用的端子保持溝41，以允許端子10的下腕 部12的後部朝下方撓曲的方式，其溝底41A朝向後方形成 爲錐狀，其溝深度依序變大。 殼體40，從第1圖判斷，在端子排列方向的兩端部， 設置有：較包含端子排列範圍的兩端的鎖定配件30彼此間 的範圍的後端緣更朝後方延伸的延伸部49。該延伸部49， 如第2圖所示，從後方觀察的形狀作成橫U字型，以從後方 收容扁平型導體F的寬度方向兩側緣（在寬度方向被卡止 部F2存在的範圍）的方式，形成有***溝45的寬度方向兩 端部分。該延伸部49，在後方的入口部在上下具有錐狀的 導入面49A、49Β»上述延伸部49的其***溝45的內側面及 上下內面，形成有：用來將所***的扁平型導體F限制其 寬度方向及上下方向的位置的限制部50。在該限制部50之 中的與扁平型導體***時的載置面相同高度的下內面，設 置有··與扁平型導體F的被卡止部F2卡止的作爲突部的卡 止突起51。該卡止突起51，從第1圖來看，是在端子排列 -16- 201203739 方向相對於鎖定配件30偏離的位置，在前後方向，從第2 圖（C)來看，設置在與鎖定配件30的鎖定部35大致相同 的位置。該卡止突起51其縱剖面作成梯形，前緣51A爲垂 直面，後緣51B爲錐狀面。該卡止突起51的上面51C是平坦 面，如顯示當可動構件在開啓位置時的第2圖（C)所示， 高度設定成：雖然位於較鎖定部35的下端更下方，而當藉 由可動構件來到關閉位置而鎖定部3 5朝下方移位時，位於 較該鎖定部35的下端更上方。當可動構件在開啓位置時， 如第2圖（A) 、（B)所示，上述卡止突起51的上面，位 在：較在端子10、20的下腕部12、22處設置的接觸部17、 27的上端更下方。 在本發明，當可動構件來到關閉位置時，鎖定部3 5與 卡止突起51，是對於扁平型導體的被卡止部F2從上方及下 方補充卡止。於是，如上述例子，當可動構件來到關閉位 置時，卡止突起51的上面51C，不一定要位於較鎖定部35 的下端更上方，也可位於較鎖定部35的下端更下方，也可 獲得上述補充達到的效果。並且，在本發明，卡止突起， 不藉由殼體形成也可以，也可在藉由殼體所保持的其他構 件，例如在補強配件形成也可以，並且，也可在具有鎖定 腕部的配件本體形成爲與鎖定部相對向。 端子10、20及鎖定配件30，如上述，在端子保持溝41 、42及鎖定配件保持溝43的溝底被堅固地保持，在與溝內 面之間形成有些許的間隙，而與該端子1 〇、20及鎖定配件 30的板面之間的間隙，藉由該端子10、20及鎖定配件3〇的 -17- 201203739 部位，有大小的差異，也就是說溝寬度有寬有窄。 如顯示在連結部13、23及33所位置的高度的橫剖面的 第4圖所示，在包含上述連結部1 3、23、3 3的各區域的端 子保持溝41、42及鎖定配件保持溝43的溝寬度，較在其他 區域的溝寬度更大，形成了寬幅部41A、42A、43A。在該 寬幅部41A、42A、43A的區域，與端子10、20及鎖定配件 30的板面之間，分別形成有：較其他區域更寬的間隙hi、 h2、h3。在本實施方式，hi = h2。相對於在端子排列方向 交互配置的該端子10、20，寬幅部41A、42A，其位置在 前後方向（在第4圖上下方向）錯開。在該第4圖，可清楚 看出上述的卡止突起51在端子排列方向其位置偏離於鎖定 配件3 0，而接近該鎖定配件3 0 »在上述第4圖的例子，是 將端子10、20的連結部13、23設置在前後方向不同的位置 ，在前後方向在與該連結部13、23對應的區域設置寬幅部 41 A、42A，寬幅部41 A、42A其位置也在前後方向錯開。 相對的，作爲不同的型態’端子1〇、20的連結部13、23， 如第5圖所示，當在前後方向位於相同位置時，寬幅部4 1 A 、42A，也可形成爲經過錐狀部而前後錯開移往寬幅部 41A、42A。並且，連結部13、23，作爲將上腕部11、21 與下腕部1 2、2 2連結的型態具有與兩腕部的間隔相當的上 下方向的長度’所以即使該連結部1 3、2 3在前後方向在相 同位置，如第6圖所示，在上下方向不同的位置設置寬幅 RH 音 &目1 。 以 以有 可置 也設 h2地 men hi轉 隔由 間自 的可 大’ 較 1 成器 形接 開連 錯在 下， 上示 ，所 A 圖 2 1 '4第 A 如 -18- 201203739 絕緣材作成的可動構件6〇。該可動構件60，位在：於殼體 40的前部形成的前部空間44。該可動構件60，涵蓋殼體40 的寬度（在端子排列方向的尺寸）而延伸，在從第2圖（A )〜（C )所示的垂立姿勢的開啓位置，到朝橫方向橫倒 的第9圖（A)〜（C)的關閉位置之間可自由轉動。該可 動構件60’是用來將朝下方的移位施加到端子10、20、鎖 定配件30的上腕部1 1、21、3丨的後部，所謂開啓位置，是 在產生該移位之前，可將扁平型導體F朝殼體40的***溝 45***的該可動構件60的位置，另一方面，所謂的關閉位 置，是產生移位而將***後的扁平型導體F朝下方壓入的 位置。 上述可動構件60，在開啓位置，如第2圖（A )〜（C )，具有從前部空間44朝上方突出的操作部61，在較該操 作部61更下方的部位，形成有前後貫穿的狹縫狀的溝部62 。該溝部62，在端子排列方向形成在與各端子10、20及鎖 定配件30對應的位置，該溝部62的溝寬度（在第2圖（A) 〜（C)在相對於紙面成直角的方向的溝內寬度尺寸）爲 稍大於對應的上述端子10、20及鎖定配件3 0的板厚度。在 溝部62的下部，設置有：作爲對於端子10、20及鎖定配件 3 0的加壓部的與各端子1〇、20及鎖定配件30對應的凸輪部 63 ' 64、65。各凸輪部63、64、65形成爲將溝部62的相對 向的溝內面彼此予以連結。 對應於端子1〇設置的凸輪部63，如第2圖（A)所示， 當可動構件60在開啓位置時’具有作成橫長的長圓形剖面 •19- 201203739 形狀，在端子10的下腕部12的前部上緣處形成的凹狀的支 承部16內，對於上腕部1 1的被壓部14具有間隔而成爲非接 觸的狀態。第2圖（A)的該凸輪部63的橫長，設定爲較同 圖的上述支承部16與被壓部14的間隔更大。於是，當可動 構件60來到關閉位置時，如後述，上述凸輪部63爲縱長姿 勢，將上述被壓部1 4朝上方按壓使其彈性移位。 與端子20對應設置的凸輪部64，如第2圖（B )所示， 當可動構件60在開啓位置時，具有將上述端子10用的橫長 的長圓形的凸輪63的右上角部變形成角狀的剖面形狀，而 與上述支承部26相接。在該圖的高度尺寸也是大於上述凸 輪部63。於是，凸輪部64在左部爲半圓形，在右部具有平 坦面且其下部作成類似圓形的形狀。該凸輪部64，當可動 構件60在開啓位置時，相對於在端子20的上腕部21處形成 的被壓部24，爲具有間隔的非接觸的狀態，當可動構件60 來到關閉位置時，成爲縱長姿勢，將該被壓部24朝上方按 壓使其彈性移位。 對應於鎖定配件30而設置的凸輪部65，雖然剖面形狀 類似上述凸輪部64，而即使可動構件60在開啓位置，也相 接於：在鎖定配件30的上腕部31處形成的被壓部34。當可 動構件60來到關閉位置時，該凸輪部65按壓上述被壓部34 使其彈性移位。 分別對應於兩種端子10、20的凸輪部63、64，當可動 構件60來到關閉位置時，從其旋轉軸線的方向，也就是在 第2圖與紙面成直角的方向觀察，是如第7圖（Α)的位置 -20- 201203739 關係。在第7圖（A )，當可動構件60在關閉位置時，成爲 縱長姿勢的凸輪部63與凸輪部64，從端子10的被壓部14與 支承部1 6分別受到相同力的反作用力A、B，從端子20的被 壓部24與支承部26分別受到相同力的反作用力C、D。朝其 中一方的凸輪部63的反作用力A、B，其作用線一致而在通 過凸輪的旋轉中心P的一條線X上。相對的，在另一方的凸 輪部64，藉由其寬度較凸輪部63更寬，且上端的圓弧偏向 右側，讓來自被壓部24的反作用力C位於較上述凸輪部63 的反作用力A更右邊，來自支承部26的反作用力作用於凸 輪部64的平坦的底面，所以反作用力D的中心成爲其中心 位置，結果會具有與上述反作用力C相同線Y上的作用線。 也就是說，當同時看凸輪部63、64時，反作用力A與B在一 條線X上達成平衡，且反作用力C與D會在離開線X的其他 線Y上達成平衡。於是，在凸輪部63、64的兩方，在互相 離開上述凸輪的旋轉中心P的位置承受，在上下方向平衡 的反作用力A、B及同樣在上下方向的平衡的反作用力C、 D，在關閉位置的可動構件60，在關閉位置，會成爲中立 狀態。可動構件60，即使從該中立狀態，朝開啓位置方向 或其相反方向偏移，因爲上述兩條線X、Y上的反作用力A 、8及（：、D造成的力矩，而會回到當初的中立狀態，能穩 定保持中立狀態。 該中立狀態，將兩種凸輪部63、64的反作用力B、D相 對於反作用力A、C的位置關係置換也能獲得。在第7圖（ B)，當可動構件在關閉位置時，以讓兩種凸輪部63、64 -21 - 201203739 的長軸交叉的方式形成兩凸輪部的話’其中一方的凸輪部 63的反作用力A、B的作用線互相錯開’且另一方的凸輪部 64的反作用力C、D的作用線也互相錯開。可是，同時觀察 兩種凸輪部63、64的話’四種反作用力八、8、（：、〇’與 第7圖（A )的情況相比，只要將反作用力B、D的位置對 調，則全體與第7圖（B )時同樣達成平衡。在該情況’中 立狀態也很穩定。 接著，針對該構成的本實施方式的電路基板用電連接 器，說明其使用方法。 (1) 首先，將如第1圖所示的連接器1配置在電路基 板（沒有圖示）的預定位置，將端子1 〇、20的連接部1 8、 28與鎖定配件30的固定腳38的兩者，與電路基板的各個對 應部焊接。銲錫可能會從在下腕部12、22、3 2處形成的上 述連接部18、28及固定腳38，沿著端子10、20及鎖定配件 30的各個板面而上升。可是，端子10、20及鎖定配件30的 下腕部12、22、32，僅以連結部13、23、33連結於上腕部 1 1、2 1、3 1，所以即使假設銲錫上升，銲錫爲了達到上腕 部1 1、2 1、3 1，銲錫必須通過該連結部1 3、2 3、3 3。可是 ，從第4圖〜第6圖看來，相對於連結部13、23、33，殻體 4〇在寬幅部41 A、42 A、43 A形成有很大的間隙，所以銲錫 上升在該處停止，不會到達上腕部11、21、31。該阻止銲 錫上升的效果，針對助焊劑（flux )也能同樣得到。 (2) 接著，如第2圖（A)〜（C)所示，將可動構件 60帶到垂立的開啓位置，準備扁平型導體F的***。在該 -22- 201203739 可動構件60處於開啓位置的狀態，端子10、20及鎖定配件 30的被壓部Μ、24、34’沒有從可動構件60的對應凸輪部 63、64、65受到任何力量，於是，按壓部15、25、35沒有 移位在最初的位置’端子1〇、20’在容易接收扁平型導體 F的狀態。鎖定配件30 ’如上述’其按壓部35在與扁平型 導體F的***路線干涉的位置。 (3)然後，如第8圖（Α)〜（C)所示，將扁平型導 體F朝殻體40的***溝45***。此時’扁平型導體F，在與 端子10、20相接之前，藉由在朝後方延伸的殼體4 0處設置 的延伸部49的限制部50 ’限制在上下及側方的位置，在預 定位置***。於是，當***時，端子1〇、2 0不會從扁平型 導體F受到過度的力量。當扁平型導體F***時，如上述， 可動構件60在開啓位置，端子10、20的按壓部15、25，尙 未朝下方移位，對於端子1〇、20，扁平型導體F容易地進 入到上腕部11、21與下腕部12、22之間。當扁平型導體F ***時，鎖定配件30，如上述，鎖定部35在與扁平型導體 F干涉的位置，所以扁平型導體F以其前端一邊將該鎖定部 35推起一邊前進。鎖定腕31Α，從扁平型導體F***前，朝 向後上方傾斜，所以當以鎖定部35的傾斜的後緣35Β承受 來自扁平型導體F的抵接力時，藉由朝上方的分力而朝傾 斜增大的方向撓曲移位，扁平型導體F容易前進。當扁平 型導體F前進至預定位置時，如第8圖（C)所示，鎖定部 35伸入到作爲扁平型導體F的缺口部的被卡止部F2，成爲 以前緣35Α可相對於該被卡止部F2的前緣卡止的狀態。在 -23- 201203739 該狀態，上述鎖定腕3 1 A，回到當初的傾斜度。從第8圖（ C )可看出，上述鎖定部35從上方伸入到扁平型導體F的被 卡止部F2，並且雖然該扁平型導體F相對於殼體40的卡止 突起51是位於上方，而在前後方向上述被卡止部F2是在該 卡止突起51的位置，成爲可與在端子排列方向設置在與鎖 定部35不同位置的該卡止突起51卡止的狀態。 (4 )接著，將可動構件60，如第9圖所示朝順時鐘方 向帶到關閉位置。在該關閉位置，可動構件60的凸輪部63 、64、65成爲縱長姿勢，凸輪部63將端子10的被壓部14朝 上方按壓抬起，凸輪部64將端子20的被壓部24朝上方按壓 抬起，凸輪部65將鎖定配件30的被壓部34朝上方按壓抬起 。當將被壓部14、24、3 4抬起時，端子10、20及鎖定配件 30的上腕部11、21、31，分別將連結部13、23、33作爲支 點，利用槓桿原理，較該連結部13、23、3 3更後方的部分 朝下方傾斜，讓後端的按壓部1 5、25朝下方移位。端子1 0 、20，藉由其按壓部15、25，將扁平型導體F朝下方按壓 ，提高該扁平型導體F與端子10、20的接觸部17、27的接 觸壓力而確實電連接，得到正式的連接狀態。另一方面， 鎖定配件30，讓朝向後上方傾斜的鎖定腕3 1 A以減少其傾 斜度的方式朝下方撓曲移位，成爲水平位置。在該水平位 置，鎖定部35朝下方移位至與下腕部32相接，更加強與上 述扁平型導體F的被卡止部F2的卡止。並且，扁平型導體F 藉由端子10' 20的按壓部15、25朝下方按壓而下降，所以 成讓上述殼體40的卡止突起51進入到上述被卡止部F2內的 -24- 201203739 狀態。扁平型導體F ’朝該被卡止部F 2內，鎖定部3 5從上 方進入，卡止突起51從下方進入，朝後方拉扁平型導體f 時的卡止力會強力作用。在該狀態，也就是在可動構件60 在關閉位置的狀態，凸輪部63、64，在第7圖（A )的狀態 ，確實維持中立狀態，即使可動構件6 0些許朝任何方向旋 轉，都能回復原本的中立狀態。 (5)當扁平型導體F在正式的連接狀態時，當有不經 意的外力朝後方也就是朝拔出方向拉時，扁平型導體F的 被卡止部F2的前緣，會將鎖定配件30的鎖定部35在其前緣 35 A朝後方按壓。該前緣35 A是垂直的，所以與被卡止部 F2堅固地卡合，受到朝後方的反作用力，將鎖定腕31八朝 後方拉。可是，該鎖定腕31A，當可動構件6 0在關閉位置 時，朝向水平方向，對於水平方向沒有傾斜，所以即使受 到上述反作用力導致的拉伸力，也不會產生朝上方的分力 ，維持該水平方向的姿勢，鎖定功能不會變弱。上述前緣 3 5 A，即使沒有完全垂直，即使稍微上下傾斜，只要實質 上爲垂直即可。 本發明，並不限定於第1圖〜第9圖所示的型態，可進 行各種變更。例如，形成於殼體的突部不需要作成卡止突 起，也可在扁平型導體的被卡止部的周邊，形成爲較該扁 平型導體用的載置面更高的型態。在第1〇圖的情況，殼體 40，對於扁平型導體F***時的載置面52，形成有在鎖定 配件30的周邊變高的突部5 Γ 。該突部5 Γ ，從第1 1圖（ A) 、（ B)可看出，形成爲從鎖定配件30的鎖定部35的前 -25- 201203739 方周邊朝前方延伸。在該型態，當可動構件60來到關閉位 置時，扁平型導體F，在端子排列範圍被朝向上述載置面 52朝下方按壓，在被卡止部F2存在的側部，藉由上述突部 51’相對地抬起，在寬度方向彎成凹狀。也就是說，將被 卡止部F2朝上抬起而與鎖定部35確實地卡止。 接著，在上述的實施方式，鎖定配件30的上腕部31的 鎖定腕31A，可動構件60在開啓位置，被壓部34沒有從該 可動構件60受到任何力，朝向後上方傾斜，當可動構件60 來到關閉位置時，上述上腕部31的被壓部34被可動構件60 的凸輪部65按壓，藉由讓鎖定腕31A成爲水平方向的姿勢 ，讓鎖定部35朝下方移位，而在第12圖所示的本實施方式 ，也可在開啓位置，上述上腕部31從凸輪部63受到力，鎖 定腕3 1 A成爲朝後上方傾斜的姿勢，在關閉位置，解除該 力量而採取水平方向的姿勢。 在第12圖（A)，可動構件60，在操作部61的下緣且 作爲與溝部62的交界的部分，具有大致半圓形的凸輪部65 作爲加壓部。該凸輪部65，當如第12圖（A)所示的可動 構件60在開啓位置時，會滑起到：鎖定配件30的上腕部31 的前部的上緣處形成的被壓部34，將該被壓部3 4朝下方按 壓。於是’作爲上腕部31的後部的鎖定腕31A，以連結部 33爲支點，移位成朝後上方傾斜的姿勢。當可動構件60繞 著軸部66轉動，帶到第1 2圖（B )所示的關閉位置時，上 述凸輪部65從被壓部34脫離，解除鎖定腕3 1 A的移位，該 鎖定腕3 1 A成爲水平狀態的姿勢。 -26- 201203739 本發明，當對應於在扁平型導體的上面形成導體部的 情況時，端子在下腕部不需要具有接觸部，上腕部的按壓 部可兼作接觸部而與上述導體部接觸。也可混合：在下腕 部具有接觸部的端子、以及上腕部的按壓部兼作接觸部的 端子’作成所謂的交錯式配置。 【圖式簡單說明】 第1圖是顯示作爲本實施方式的電路基板用電連接器 、與***於該連接器的扁平型導體的一部分的立體圖。 第2圖是針對第1圖的連接器，可動構件在開啓位置且 扁平型導體***前的剖面圖，（A )是在端子排列方向，

[PRIOR ART DOCUMENT] [Patent Document 1] [Patent Document 1] Japanese Patent Laid-Open No. 2004-221067 [Problem to be Solved by the Invention] The connector of Patent Document 1, In order to prevent the flat conductor from being inadvertently removed, Only the locking portion of the locking fitting is locked to the locked portion of the flat conductor, and, The locking portion is opposite to the face of the flat conductor, That is, the one side is locked to the above-mentioned locked portion. but, The lock portion is formed in a substantially inverted triangle shape. then, Although the contact portion of the flat conductor and the terminal has a predetermined contact pressure and is in a formal connection state, And when the flat conductor is pulled strongly in the pull-out direction, The locked portion of the flat conductor, Bringing the force of the pull-out direction to the front bevel of the above-mentioned substantially inverted triangular locking portion, the force, Producing a component upward toward the front bevel, result, Rescuing the rear of the upper wrist of the locking accessory upwards, The amount of displacement of the rear portion, that is, the locking portion is reduced. That is, Will produce: The locking amount of the locking portion and the locked portion is reduced, Or the case where such an inadvertent flat conductor falls off. The present invention is directed to this situation, An electrical connector for a circuit board using a locking fitting, The subject is to provide an electrical connector for a circuit board. In the formal connection state of the flat conductor, Even if you inadvertently have a strong force acting on the pull-out direction of the flat conductor, The lock of the locking part and the locked part -6- 201203739 can also be kept at any time. Alternatively, it is possible to surely prevent the falling off by reinforcing the locked portion so that the locked state does not change. [Means for Solving the Problem] The electrical connector for a circuit board of the present invention, Is configured on the circuit board, An electrical connector that electrically connects the inserted flat conductor to the circuit substrate, Is with: The settings are: a contact portion that maintains a flat surface of the metal plate and is in contact with the flat conductor, a connection portion connected to the circuit board, Pressing the pressing portion of the flat conductor, And a pressed portion for receiving a force for displacing the pressing portion in the pressing direction, a plurality of terminals arranged at right angles to the plate surface; The settings are: In the same manner as the terminal, the flat plate surface of the metal plate is maintained, and the locking portion that is locked by the flat conductor is locked. And a pressed portion for receiving a force for displacing the locking portion, a locking fitting configured to be parallel to the terminal; Forming a receiving space for receiving the connecting portion of the inserted flat type conductor, The terminal is held at a position where the contact portion is in contact with the flat conductor, And retaining the housing of the locking accessory; And a pressurizing portion provided with a pressed portion for applying a force to the terminal and the locking fitting, Can be: The open position of the flat conductor can be inserted, Pressing the contact portion of the flat conductor toward the terminal, And a movable member that moves the locking portion between the closed positions of the locked position; The above terminals and locking accessories, By inserting the flat conductor 201203739 into the upper wrist and the lower wrist as the long axis direction, The middle position in the long axis direction is formed by the joint of the joint portion, Terminal, The upper wrist portion has a pressed portion at a front portion of the front side closer to the insertion direction of the flat conductor than the joint portion, There is a pressing portion at the rear, The locking fitting has an upper portion having a pressed portion at the front portion, There is a protruding locking portion at the rear. Electrical connector for circuit board, In the present invention, a housing or a member held in the housing, have: The mounting surface for inserting the flat conductor is formed as a high protrusion. The locking portion and the projection function from the top to the bottom for the flat conductor. In the present invention of this configuration, When the flat conductor is inserted into the predetermined position on the mounting surface, The locked portion of the flat conductor, Relative to the protrusion formed by the member held by the casing or the casing, In the forward position, In the upper and lower directions, that is, the thickness direction of the flat conductor, Has a repeat range with the protrusion, When the force of the pull-out direction acts on the flat conductor, The positional relationship (positional relationship of the former) that is locked in the protrusion, Or the periphery of the locked portion is located on the protrusion. The positional relationship in which the flat conductor is bent upward in the portion (the positional relationship of the latter). The positional relationship of the former, Relative to the locked portion of the flat conductor, The locking portion of the locking fitting is locked from above, In the terminal arrangement direction at a position different from the locking portion, a projection formed by a member held in the housing or the housing, Get stuck from below. Relative to the above-mentioned locked portion, Since the locking portion and the protrusion are locked from above and below, Therefore, the flat conductor remains locked in any direction up and down. and, The flat conductor is pressed downward at the pressing portion of the terminal. Therefore, the locking of the locking portion of the housing -8-201203739 is in ample range, Even if the force toward the flat conductor is accompanied by the upward force, Lift the flat conductor, It is also locked by the force from the pressing portion and by the locking portion of the locking fitting. then, In the case of the positional relationship of the latter, Since the periphery of the locked portion of the flat conductor is located on the protrusion, So when lifting the position of the locked portion, It is not locked with the protrusion in the front and rear direction. but, By the lifting, the engagement between the engaged portion and the locking portion is deepened. then, Even if the flat conductor is lifted upwards, Of course, the force from the pressing portion is also locked to the locking portion. Even if it is offset downwards, The lifting force from the protrusions does not increase the offset and secures the locking with the locking portion. In the present invention, The protrusion can be made into: It can be locked in the front and rear direction with the locked portion of the flat conductor. Further, it is provided as a locking projection located on the lower surface side of the flat type conductor. In this case, The locked portion of the flat conductor, Will have a repeating range with the locking projection in the up and down direction, result, It becomes a position to lock in the front and rear direction. In the present invention, Locking the locking portion of the fitting and the locking projection of the housing, Its position is used to reach: The side edge of the flat conductor is formed as a notch recessed portion of the locked portion. In the present invention, The locking projection of the housing, Its location is: In the up and down direction, it is lower than the contact portion of the terminal. The flat type conductor is inserted into a contact portion disposed at the terminal, At this time, The locking projection of the housing, Is located below the contact area, Therefore, it does not become an obstacle when the flat conductor is to be inserted and removed. And on the other hand, When the connector is used, By bringing the movable member to the closed position, Press the flat guide -9- 201203739 body down, The locked portion of the flat conductor is surely brought to a position where it can be locked with the locking projection of the housing. So by having the protrusions located below the contact area, There will be no jamming. In the present invention, case, At both ends of the terminal arrangement direction, have: The flat conductor is limited in the vertical direction and the terminal arrangement direction. The restriction, have: An extension extending in the front-rear direction toward the rear of the terminal. By doing this way, Then when the flat conductor is inserted, Before the flat conductor is connected to the contact portion of the terminal, The position of the up-and-down direction and the terminal arrangement direction is determined by the restriction portion. So in the above direction, The flat conductor does not have extra movements. Smooth insertion at a predetermined location, Will not damage the contact. and, In the present invention, Terminal, The lower wrist portion is at a position corresponding to the pressing portion in the front-rear direction, Has a contact portion. By arranging the pressing portion and the contact portion in the front-rear direction at the corresponding positions, The contact between the contact portion and the flat conductor can be more reliable and stable. In the present invention, Projection, In the position where the terminals are arranged differently from the locking fittings, Higher formation to: When the movable member is in the closed position, A position higher than the lower end portion of the locking portion of the locking fitting. With this, Locking portion and protrusion, The amount of engagement with the locked portion of the flat conductor becomes large. [Effect of the Invention] As described above, In the present invention, a member held by the housing or the housing, In the position where the terminals are arranged differently from the locking fittings, With a protrusion, The projection -10- 201203739 is formed relatively high with respect to the mounting surface for inserting the flat conductor: When the movable member is in the closed position, More than the lower end of the locking portion of the locking fitting, Therefore, when the flat conductor is inserted into the predetermined position on the mounting surface, The locked portion of the flat conductor, a protrusion formed by a member held by a casing or a casing, In the front position, in the up and down direction, that is, in the thickness direction of the flat conductor, Working with the protrusion, So when the force of the pull-out direction acts on the flat conductor, Become a positional relationship that is locked in the protrusion, Or the periphery of the locked portion is located on the protrusion. a flat conductor in which the portion is bent upward, The positional relationship of the former, The flat conductor is in a state of being shifted up and down, A strong force that is inadvertently pulled out in the direction of pulling out, One of the locking portion and the protruding portion is in a weakly locked state. The other side will also become a strong stuck state. So with the combined effect of the two, Can be fully locked at any time, It is sure to prevent the flat conductor from coming off. and, The flat conductor is pressed downward at the pressing portion of the terminal. So the upper wrist of the locking fitting that forms the locking portion, Will also prevent the production like: The locked portion of the flat conductor is detached from the projection of the housing and is excessively displaced from the locking portion of the locking fitting, Therefore, the above-described locking from the upper and lower locking portions and the locking projection can be stably ensured. And in the case of the positional relationship of the latter, The periphery of the locked portion of the flat conductor is located on the protrusion, So although the locked portion is in the raised position, The protrusion is not locked in the front and rear direction, And by lifting it up, The engagement between the engaged portion and the lock portion is deepened. then, Even if the flat conductor is lifted up, Of course, it is locked in the locking portion by the force from the pressing portion. Even if it is biased downward, By the lifting force from the above-mentioned protrusion, Will not increase the offset, Make sure that -11 - 201203739 is locked with the locking part.
