DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a connector, and more particularly to a relay connector or a rear locking connector having a zero insertion force (ZIF) structure for making two pieces of The flexographic printed boards (hereinafter referred to as "FPC") are connected to each other. [Prior Art] Previously, a relay connector having a ZIF structure for an FPC has, for example, a case where the first and second flexible substrates 3, 4 are inserted into the casing 9 for positioning, by sliding the cover 25 In the sliding manner, the flexible substrates 3, 4 are elastically contacted at the opposite end portions 17, 19 of the contact member 1 by a predetermined contact pressure, so that the first and second flexible substrates 3, 4 are mutually Electrical connector (refer to Patent Document 1). Further, in the case of the relay connector having the ZIF structure for the FPC, there is a type in the substantially meandering contact member 10 incorporated in the outer casing 20, and the rotating beam 1 is rotated by the rod 30 so that the contact beam 12 is in contact. The portion 16 is in contact with the FPC 40 and is electrically connected (see Patent Document 2). [Patent Document 1] Japanese Patent Laid-Open Publication No. Hei 9- No. Hei. No. Hei. No. Hei. The active contact of the contact is contacted on one side, and the other side is contacted inside the outer casing. Therefore, only one of the upper or lower sides of the front end portion can be connected to the FPC with the connection pad, which defines the connectable FPC, and the use convenience is not good. Moreover, as the device is miniaturized, the components of the connector must also be miniaturized. 1299224
L 但若要確保高度接觸可靠性，則須有高的零件精確度、組裝 精確度，而有製造、組裝耗時、生産性低的問題。 本發明係鑑於前述問題，其課題在於提供一種連接器， 可連接一端部的上下面之任一面設有連接焊墊的FPC，使用 方便性佳，製造、組裝容易且接觸可靠性高。 本發明相關之連接器係爲了解決前述課題，將可撓印刷 基板一端部插入在外殻内，且藉由使壓接構件動作的方式， 將保持在前述外殼内的接觸件的主動接點，壓接在前述可撓 • 印刷基板一端部且電氣連接者，其係構成藉由突設在前述接 觸件的從動接點、和形成與前述從動接點相對且彈壓在前述 從動接點側的主動接點，來挾持前述可撓印刷基板一端部且 電氣連接。 根據本發明，由於藉由從動接點及主動接點挾持FPC — 端部且電氣連接，即使是設在FPC—端部上下面之任一面的 連接焊墊亦可連接，使用方便性佳。 且，接觸件的主動接點係彈壓在從動接點側，且主動接 ® 點和從動接點挾持設在FPC—端部的連接焊墊，因此即使當 外殼或接觸件等的構成零件的尺寸精確度、組裝精確度不穩 定時，前述主動接點將變位以吸收、緩和前述外殻等之變 動。因此，由於從動接點或主動接點之至少任一方經常地壓 接在設於FPC—端部的連接焊墊，故可維持接觸可靠性且容 易製造及組裝。 本發明相關之實施形態上，亦可構成一種藉由將可撓印 刷基板一端部插入在外殼内，將前述可撓印刷基板一端部壓 1299224 接在保持於前述外殻内的接觸件的主動接點且電氣連接之 連接器，藉由從前述接觸件以可彈性變形方式延伸的從動接 點、和形成與前述從動接點相對且彈壓在前述從動接點側的 主動接點，來挾持前述可撓印刷基板一端部且電氣連接。 根據本實施形態，除了前述效果之外，由於從動接點係 從接觸件以可彈性變形方式延伸，因此從動接點吸收、緩和 零件精確度、組裝精確度的變動，並追從外力所造成的FPC 變位，而有獲得一種接觸可靠性更高的連接器之效果。 •【實施方式】 根據第1圖至第17圖之附圖，說明本發明相關之連接 器之實施形態。 第1實施形態係如第1圖至第15圖所示，應用於中繼 用連接器10之情形，係由外殻20、第1、第2接觸件30、 40、暫時固定零件50、操作桿60、第1、第2FPC70、80所 構成。 外殼20係如第4圖所示，在與外殼本體2 1相對的正面 ® 及背面各自形成有相互連通之開口部21a、21b，且從相對的 兩側面各自與腕部2 2、2 2平行地延伸。然後，如第4 B圖所 示，前述外殼本體21的背面側之中，以預定間距交替地設 有壓入溝24、25，用於將後述之第1、第2接觸件30、40 壓入從下方緣部延伸的承受部23上，。且，在位於兩端的 前述壓入構24、24外側，各自形成壓入溝26、26，用於壓 入暫時固定零件50。然後，前述腕部22係於其内向面之上 段部，形成有錐面22a及軸承部22b。再者，前述内向面之 1299224 t 攀 件30的下邊部33係吊下在連結部31，且未接觸在外殼20。 第2接觸件4 〇係第6圖所示，由正面具有大致Η形狀 的導電性板簧材料所構成。即，從連結部41上端部在兩側 延伸有上邊部42，此外從其下端部在兩側延伸有下邊部43。 前述上邊部42之一端側形成有扣止爪42a，此外另一端側設 有扣合爪42b及支點部42c。且，前述下邊部43之一端側設 有弟1主動接點4 3 a，且另一·端側設有第2主動接點4 3 b。 再者’前述上邊部42的下邊緣部之中，從動接點44a係從 春前述連結部4 1上端部附近，延伸成與前述第1主動接點43a 相對’且前述從動接點44a基部突設有扣止用突起44b。然 後’在前述上邊部42的前述連結部4 1附近，加工形成有突 出的壓入用突起44c。 然後’前述第2接觸件40係如第2B圖所示，藉由從開 □部21b壓入在設於前述外殻20的壓入溝25之方式，扣止 爪42a及扣止用突起44b係扣止在外殼20内部，且前述扣 合爪42b係扣合在開口部2 1 a上方緣部而止脫。此時，前述 ®第2接觸件40的下邊部43係吊下在連結部4 1，且未接觸在 外殼2 0。 此外，從第2B、2C圖得知，藉由將前述第丨、第2接觸 件30、40各自組入在前述外殻20的方式，第1接觸件30 的從動接點34a及第1主動接點33a，係比第2接觸件40的 從動接點44a及第1主動接點43a，更位於外殼20的深度側。 因此，前述第1、第2接觸件30、40係在不同的位置各自電 性連接於後述第1 FPC70。 1299224 τ 同樣地’第1接觸件30之第2主動接點33b，係比第2 接觸件之第2主動接點43b更位於外殼2〇之深度側。因此， 上述第1、第2接觸件3〇, 34係在不同的位置，分別電性連 接於後述之第2 FPC80。 暫時固定零件50係如第7圖所示，由正面具有大致Η 形狀的板簧材料所構成。即，從連結部5 1上端部在兩側延 伸有上邊部52 ’此外從其下端部在兩側延伸有下邊部53。 前述上邊部52—端側形成有扣止爪52a，此外另一端側設有 • 扣合爪52b。且，前述下邊部53—端側設有可動爪53a，此 外另一端側設有操作部53b。再者，前述上邊部52的下邊緣 部之中，在前述連結部51上端部附近突設有扣止用突起54a。 然後，前述暫時固定零件50係如第13B圖所示，藉由 壓入設在前述外殼20的壓入溝26的方式，扣止爪52a及扣 止用突起54a係扣止在外殼20内部，且前述扣合爪52b係 扣合在開口部21b上方緣部而止脫。此時，前述暫時固定零 件50的下邊部53係吊下在連結部51，且未接觸在外殼20。 Φ 操作桿6 0係如第8圖所示，從桿本體6 1兩側端部’各 自延伸有延伸部62、62。在前述桿本體6 1以預定間距交替 地並設有開縫63、64。在前述開縫63、64内’形成跨設之 操作部63a、64a，該操作部63a、64a係壓接在前述第1、第 2接觸件30、40的支點部32b、42c (第2B、2C圖）。 另一方面，在前述延伸部62的外向面，將旋轉軸65各 自突設在同一軸心上’並將暫時固定用突部66各自突設在 同一軸心上。且，在前述延伸部62内向面，各自突設有推 -11- 1299224 壓部67，在前述推壓部67外周面，各自形成有壓接用肋 67 a(第8C圖）。再者，在前述延伸部62外周緣部，各自突設 有扣合爪部6 8。 然後’前述操作桿60係將前述旋轉軸65，沿著前述外 殼20的錐面22a推入，藉由使前述腕部22彈性變形的方式， 將前述旋轉軸65嵌合在軸承部22b，並將前述暫時固定用突 部66嵌合在前述外殼20的第1凹部22c。 因而，如第1 1圖及第12圖所示，藉由使操作桿60伏 φ 倒的方式，暫時固定用突部66係以旋轉軸65爲中心，依序 扣合在第1、第2、第3凹部22c、22d、22e，並藉由扣合爪 部68扣合在外殻20的第1凹部22c的方式，成爲鎖定狀態。 第1FPC70係如第9圖所示，爲了易於進行對前述外殼 20的組裝作業，將補強板7 1從內面墊在可撓樹脂膜一端部 的下面，而形成有不折曲的前端部72。且，在前述前端部 72上面將2種連接焊墊73、74，以預定間距交替地設成交 錯狀。再者，前述第1FPC係於其前端部72兩側，各自形成 φ 有暫時固定用缺口部75。 第2FPC80係如第10圖所示，爲了易於對前述外殼20 的組裝作業，將補強板81從內面墊在可撓樹脂膜一端部的 上面，而形成有不折曲的前端部8 2。且，在前述前端部8 2 下面將2種連接焊墊83、84,以預定間距交替地設成交錯狀。 接著，說明關於在由前述構成零件所構成的中繼用接觸 件10，連接第1、第2FPC70、80的方法。首先，如第13圖 所示，操作桿60的暫時固定用突部66係扣合在第1凹部部 1299224 * * 22c，並藉由操作部63a、64a壓接在第1、第2接觸件30、 40的支點部42c，32b的方式，支持成不搖動。 然後，如第14圖所示，從外殼20的開口部21 a及開縫 21c插入第1FPC70的前端部72，且抵接在外殻20内的定位 部21d。然後，將前述操作桿60大致垂直地拉起時，前述操 作桿60係以旋轉軸部65爲支點轉動，且暫時固定用突部66 扣合在第2凹部22d，且前述操作桿60的推壓部67將暫時 固定零件50的操作部53b下推。因此，暫時固定零件50的 • 下邊部5 3係以連結部5 1下端部爲支點轉動，且藉由可動爪 5 3a扣止在第1FPC70的缺口部75之方式，而扣止第1FPC70。 此時，操作桿60的暫時固定用突部66係扣合在第2凹部 22d，因此使操作桿60不自動復原，第1FPC70亦不脫落。 然後，如第15圖所示，將第2FPC 80從外殼20的開口 部21 b插入後，當操作桿6 0完全伏倒時，暫時固定用突部 66嵌合在第3凹部22e，且扣合爪部68扣合在第1凹部22c。 因此，如第2B、2C圖所示，操作桿60的桿本體61經由第 ® 2FPC80，將第1、第2接觸件30、40的第2主動接點33b、 43b下推。其結果，第2FPC 80的連接焊墊83、84和第1、 第2接觸件30、40的第2主動接點33b、43b各自電氣連接。 再者，第1、第2接觸件30、40的下邊部33、43係以連結 部31、4 1的下端部爲支點各自轉動，使第1接觸件3〇的從 動接點34a和第1主動接點33a挾持第1FPC70的連接焊墊 73且電氣連接。同樣地，第2接觸件40的從動接點44a和 第1主動接點43a挾持第1FPC70的連接焊墊74且電氣連接， 1299.224 而完成連接作業。 根據本實施形態，將第1FPC70暫時固定在外殻20之 後，可將第2FPC80組裝在外殼20且電氣連接，不須將第i、 第2FPC70、80同時地定位在外殻20。因此，易於進行第1、 第2FPC7 0、80的連接作業，而有提高作業性之優點。 且，根據本實施形態，如第2 B、2 C圖所示，將第丨？？〇70 沿著外殻20的上段部27上拉時，插入在前述第1FPC70的 外殼20的前端部72爲硬的板狀體，且以外殻20的定位部 • 21d爲支點，抵接在開口部21a上方緣部。但是，第1FPC70 的連接焊墊73、74係由第1、第2接觸件30、40的從動接 點3 4a、3 4a強力壓接，因此不會有降低接觸可靠性的情形。 且，第1、第2接觸件30、40的第1主動接點33a、43a係 彈壓在上方，因此不會有顯著降低接觸件壓力的情形。 另一方面，將第1FPC70沿著外殻20的下段部28下拉 時，外殻20的下段部28比上段部27更伸出。因此，將插 入在第1FPC70的外殻20内的前端部72強力地規定位置， ^ 而無前述傾斜的情形。其結果，第1、第2接觸件3 0、40之 從動接點33a、43a及第1主動接點33a、43a對第1FPC70 的連接焊墊73、74的接觸壓，各自不會有顯著降低的情形， 而不會降低接觸可靠性。尤其，第丨、第2接觸件3 0、40的 第1主動接點33a、43a係彈壓在上方，因此可防止接觸壓 顯著地降低。再者，從動接點34a、44a可若干彈性變形， 因此不會有接觸可靠性顯著降低的情形。 因此’根據本實施形態，即使將第1FPC70拉到上下方， 1299224 其接點焊墊73、74仍接觸在第1、第2接觸件30、40的從 動接點33a、43a及第1主動接點34a、44a。因此，即使在 前端部下面連接設有連接焊墊的FPC(未圖示），亦不會使接 觸可靠性降低，而獲得一種連接自由度大且泛用性佳的中繼 連接器10。且，下段部28比上段部27推出，因此易於將第 1FPC70插入外殻20時的定位，而有進一步提高連接作業性 之優點。 第2實施形態係如第1 6圖及第1 7圖所示，可安裝在印 • 刷基板，即適用於後方鎖定式連接器1 1的情形。後方鎖定 式連接器1 1係指外殼中的FPC插入位置和操作桿的安裝位 置爲位於相反側的連接器。 本實施形態相關之外殻20係如第1 7 B圖所示，在要插 入FPC的（未圖示）開口部21a兩側緣部，突設有上段部27 和下段部27。尤其，前述上段部27係位於比前述下段部28 推出在外方之位置，而與第1實施形態同樣，可防止FPC拉 到上下方向所造成的不良情形。 ® 且’接觸件90係由正面具有大致η形狀的導電性板簧 材料所構成者。即，從連結部91上端部在兩側延伸有上邊 部9 2 ’此外從其下端部在兩側延伸有下邊部9 3。前述上邊 部92之一端側形成有主動接點92a，此外另一端側設有操作 部9 2b °且’前述下邊部93的一端側設有扣止爪93a，此外 另一端側設有支點部93b。再者，前述下邊部93的上邊緣部 之中’從動接點94係從前述連結部9丨下端部附近，延伸成 與前述主動接點92a相對。 -15- 1299224 然後’前述接觸件90係藉由壓入設在前述外殼20的壓 入溝25的方式，將扣止爪93a扣止在外殼20内而止脫。此 時，前述接觸件90的上邊部92係支持在連結部9 1，未接觸 在外殼20。因此，藉由轉動安裝在前述外殻20的操作桿60 的方式，推壓部69將前述上邊部92刃操作部92b上推，以 連結部9 1的上端部爲支點轉動前述上邊部9 2，且以從動接 點94和主動接點92a挾持未圖示的FPC的連接焊墊部並電 氣連接。其它因爲和前述第1實施形態大致同樣，因此在同 Φ —部分附加同一符號而省略說明。 本發明相關之連接器亦可適用於前述中繼用連接器及 後方鎖定型連接器以外的連接器。 【圖式簡單說明】

However, in order to ensure high contact reliability, high part accuracy and assembly accuracy are required, and manufacturing, assembly, and production are low. The present invention has been made in view of the above problems, and an object thereof is to provide a connector which can be connected to an FPC having a connection pad provided on either one of the upper and lower surfaces of one end portion, which is easy to use, easy to manufacture and assemble, and high in contact reliability. In order to solve the above problems, the connector according to the present invention inserts one end portion of the flexible printed circuit board into the casing, and operates the pressure contact member to press the active contact of the contact member held in the casing. Connected to one end of the flexible printed circuit board and electrically connected, the structure is formed by a driven contact protruding from the contact member and formed opposite to the driven contact and biased on the driven contact side The active contact contacts the one end of the flexible printed circuit board and is electrically connected. According to the present invention, since the FPC-end portion is electrically connected by the driven contact and the active contact, even the connection pads provided on either the upper and lower sides of the FPC-end portion can be connected, which is convenient to use. Moreover, the active contact of the contact is biased on the driven contact side, and the active contact point and the driven contact hold the connection pad provided at the FPC-end, so even when the component such as the outer casing or the contact member When the dimensional accuracy and assembly accuracy are unstable, the active contact is displaced to absorb and mitigate the fluctuation of the outer casing or the like. Therefore, since at least one of the driven contact or the active contact is often pressed against the connection pad provided at the end of the FPC, contact reliability can be maintained and manufacturing and assembly can be easily performed. According to an embodiment of the present invention, the movable printed circuit board may be inserted into the outer casing, and one end of the flexible printed circuit board may be pressed 1299224 to be actively connected to the contact member held in the outer casing. And a connector that is electrically connected, by a driven contact extending from the contact member in an elastically deformable manner, and an active contact that is opposite to the driven contact and that is biased on the driven contact side One end of the flexible printed circuit board is held and electrically connected. According to the present embodiment, in addition to the above-described effects, since the driven contact extends from the contact member in an elastically deformable manner, the driven contact absorbs, relaxes the accuracy of the part, the variation of the assembly accuracy, and follows the external force. The resulting FPC is displaced, and there is the effect of obtaining a connector with higher contact reliability. [Embodiment] An embodiment of a connector according to the present invention will be described based on the drawings of Figs. 1 to 17 . The first embodiment is applied to the relay connector 10 as shown in Figs. 1 to 15 and is composed of the outer casing 20, the first and second contacts 30 and 40, the temporary fixing member 50, and the operation.

Then, as shown in FIG. 4B, press-in grooves 24 and 25 are alternately provided at predetermined intervals among the back side of the casing body 21 for pressing the first and second contacts 30 and 40 which will be described later. It is inserted into the receiving portion 23 extending from the lower edge. Further, press-in grooves 26 and 26 are formed outside the press-fit structures 24 and 24 at both ends to press the temporary fixing member 50. Then, the arm portion 22 is formed on a portion above the inner surface thereof, and a tapered surface 22a and a bearing portion 22b are formed. Further, the lower edge portion 33 of the 1299224 t climbing member 30 of the inward surface is suspended from the joint portion 31 and is not in contact with the outer casing 20. The second contact member 4 is composed of a conductive leaf spring material having a substantially meandering shape as shown in Fig. 6 . That is, the upper side portion 42 extends from both sides of the upper end portion of the joint portion 41, and the lower side portion 43 extends from both sides of the lower end portion. The one end side of the upper side portion 42 is formed with a locking claw 42a, and the other end side is provided with a fastening claw 42b and a fulcrum portion 42c. Further, one end side of the lower side portion 43 is provided with a first active contact 4 3 a, and the other end side is provided with a second active contact 4 3 b. Further, among the lower edge portions of the upper side portion 42, the driven contact 44a extends from the vicinity of the upper end portion of the connecting portion 4 1 in the spring to face the first active contact 43a' and the driven contact 44a A locking projection 44b is protruded from the base. Then, in the vicinity of the connecting portion 4 1 of the upper side portion 42, a projecting press-fitting projection 44c is formed. Then, as shown in FIG. 2B, the second contact member 40 is pressed into the press-fitting groove 25 provided in the outer casing 20 from the opening portion 21b, and the locking claw 42a and the locking projection 44b are fastened. The buckle is fastened inside the outer casing 20, and the fastening claw 42b is fastened to the upper edge of the opening portion 21a to be stopped. At this time, the lower side portion 43 of the second contact member 40 is suspended from the joint portion 41 and is not in contact with the outer casing 20. Further, as is apparent from FIGS. 2B and 2C, the driven contact 34a and the first contact of the first contact 30 are formed by incorporating the second and second contacts 30 and 40 into the outer casing 20, respectively. The active contact 33a is located further on the depth side of the outer casing 20 than the driven contact 44a and the first active contact 43a of the second contact 40. Therefore, the first and second contacts 30 and 40 are electrically connected to the first FPC 70, which will be described later, at different positions. 1299224 τ Similarly, the second active contact 33b of the first contact 30 is located further on the depth side of the casing 2 than the second active contact 43b of the second contact. Therefore, the first and second contacts 3, 34 are electrically connected to the second FPC 80, which will be described later, at different positions. The temporary fixing member 50 is composed of a leaf spring material having a substantially Η shape on the front side as shown in Fig. 7. That is, the upper side portion 52' is extended from both sides of the upper end portion of the joint portion 5 1 and the lower side portion 53 is extended from both sides of the lower end portion. The upper side portion 52 is formed with a locking claw 52a on the end side, and the other end side is provided with a fastening claw 52b. Further, the lower side portion 53 is provided with a movable claw 53a on the end side, and the other end side is provided with an operation portion 53b. Further, among the lower edge portions of the upper side portion 52, a locking projection 54a is protruded in the vicinity of the upper end portion of the coupling portion 51. Then, as shown in FIG. 13B, the temporary fixing member 50 is press-fitted into the press-fitting groove 26 of the outer casing 20, whereby the locking claw 52a and the locking projection 54a are fastened inside the outer casing 20. Further, the engaging claws 52b are fastened to the upper edge of the opening 21b to be stopped. At this time, the lower side portion 53 of the temporary fixing member 50 is suspended from the connecting portion 51 and is not in contact with the outer casing 20. Φ The operating lever 60 is an extension portion 62, 62 extending from the end portions 'on both sides of the lever main body 6 1 as shown in Fig. 8. The slit bodies 63 are alternately provided at predetermined intervals in the foregoing rod main body 61, and slits 63, 64 are provided. The operation portions 63a and 64a are formed in the slits 63 and 64, and the operation portions 63a and 64a are crimped to the fulcrum portions 32b and 42c of the first and second contacts 30 and 40 (second B, 2C picture). On the other hand, on the outward direction of the extending portion 62, the rotating shafts 65 are respectively protruded from the same axis "and the temporary fixing projections 66 are respectively projected on the same axis. Further, in the inner surface of the extending portion 62, a pressing portion -11-1299224 is formed, and a pressing rib 67a (Fig. 8C) is formed on each of the outer peripheral surfaces of the pressing portion 67. Further, a fastening claw portion 68 is protruded from the outer peripheral edge portion of the extending portion 62. Then, the operation lever 60 pushes the rotation shaft 65 along the tapered surface 22a of the outer casing 20, and the rotation shaft 65 is fitted to the bearing portion 22b so that the wrist portion 22 is elastically deformed. The temporary fixing projection 66 is fitted to the first recess 22c of the outer casing 20. Therefore, as shown in FIGS. 1 and 12, the temporary fixing projection 66 is engaged with the first and second portions in the order of the rotation shaft 65 by reversing the operation lever 60 volts φ. The third recessed portions 22c, 22d, and 22e are locked in a state in which the engaging claw portion 68 is engaged with the first recessed portion 22c of the outer casing 20. As shown in Fig. 9, the first FPC 70 is formed so as to facilitate the assembly work on the outer casing 20, and the reinforcing plate 71 is placed on the lower surface of one end portion of the flexible resin film from the inner surface to form a front end portion 72 that is not bent. . Further, two types of connection pads 73 and 74 are alternately disposed on the front end portion 72 at predetermined intervals. Further, the first FPC is formed on both sides of the front end portion 72, and each of the φ has a temporary fixing notch portion 75. As shown in Fig. 10, in the second FPC 80, in order to facilitate the assembly work of the outer casing 20, the reinforcing plate 81 is placed on the upper surface of one end portion of the flexible resin film from the inner surface, and a front end portion 8 2 which is not bent is formed. Further, two kinds of connection pads 83 and 84 are alternately arranged in a staggered manner at a predetermined pitch under the front end portion 8 2 . Next, a method of connecting the first and second FPCs 70 and 80 to the relay contact 10 composed of the above-described components will be described. First, as shown in Fig. 13, the temporary fixing projection 66 of the operation lever 60 is fastened to the first recessed portion 1299224**22c, and is crimped to the first and second contacts by the operation portions 63a and 64a. The fulcrum portions 42c and 32b of 30 and 40 are supported so as not to be shaken. Then, as shown in Fig. 14, the front end portion 72 of the first FPC 70 is inserted into the opening portion 21a of the outer casing 20 and the slit 21c, and abuts against the positioning portion 21d in the outer casing 20. Then, when the operation lever 60 is pulled up substantially vertically, the operation lever 60 is pivoted about the rotation shaft portion 65, and the temporary fixing projection 66 is engaged with the second recess 22d, and the operation lever 60 is pushed. The pressing portion 67 pushes down the operation portion 53b of the temporary fixing member 50. Therefore, the lower portion 5 3 of the temporary fixing member 50 is rotated about the lower end portion of the connecting portion 5 1 and the first claw portion 75 is engaged with the notch portion 75 of the first FPC 70 to lock the first FPC 70. At this time, since the temporary fixing projection 66 of the operation lever 60 is engaged with the second recess 22d, the operation lever 60 is not automatically restored, and the first FPC 70 does not fall off. Then, as shown in Fig. 15, after the second FPC 80 is inserted from the opening 21b of the outer casing 20, when the operating lever 60 is completely collapsed, the temporary fixing projection 66 is fitted into the third recess 22e, and the buckle is engaged. The claw portion 68 is engaged with the first recess 22c. Therefore, as shown in Figs. 2B and 2C, the lever main body 61 of the operating lever 60 pushes down the second active contacts 33b and 43b of the first and second contacts 30 and 40 via the second 2FPC 80. As a result, the connection pads 83 and 84 of the second FPC 80 and the second active contacts 33b and 43b of the first and second contacts 30 and 40 are electrically connected to each other. Further, the lower side portions 33, 43 of the first and second contacts 30, 40 are rotated by the lower end portions of the connecting portions 31, 41, respectively, so that the driven contacts 34a and the first contacts 3'' The active contact 33a holds the connection pads 73 of the first FPC 70 and is electrically connected. Similarly, the driven contact 44a of the second contact 40 and the first active contact 43a hold the connection pads 74 of the first FPC 70 and are electrically connected, 1299.224, to complete the connection work. According to the present embodiment, after the first FPC 70 is temporarily fixed to the casing 20, the second FPC 80 can be assembled to the casing 20 and electrically connected, and the i-th and second FPCs 70 and 80 need not be simultaneously positioned in the casing 20. Therefore, it is easy to perform the connection work of the first and second FPCs 70 and 80, and the workability is improved. Further, according to the present embodiment, as shown in Figs. 2B and 2C, what is the third? ? When the 〇70 is pulled up along the upper portion 27 of the outer casing 20, the front end portion 72 of the outer casing 20 inserted into the first FPC 70 is a hard plate-like body, and the positioning portion 21d of the outer casing 20 is used as a fulcrum to abut the opening. The upper edge of the portion 21a. However, since the connection pads 73 and 74 of the first FPC 70 are strongly pressed by the driven contacts 34a and 34a of the first and second contacts 30 and 40, the contact reliability is not lowered. Further, since the first active contacts 33a and 43a of the first and second contacts 30 and 40 are biased upward, the contact pressure is not significantly lowered. On the other hand, when the first FPC 70 is pulled down along the lower portion 28 of the outer casing 20, the lower portion 28 of the outer casing 20 projects more than the upper portion 27. Therefore, the distal end portion 72 inserted into the outer casing 20 of the first FPC 70 is strongly defined in position, and there is no such inclination. As a result, the contact pressures of the driven contacts 33a and 43a and the first active contacts 33a and 43a of the first and second contacts 30 and 40 to the connection pads 73 and 74 of the first FPC 70 are not significantly different. Reduced conditions without reducing contact reliability. In particular, since the first active contacts 33a and 43a of the second and second contacts 30 and 40 are biased upward, the contact pressure can be prevented from being remarkably lowered. Further, the driven contacts 34a, 44a can be elastically deformed a plurality of times, so that there is no case where the contact reliability is remarkably lowered. Therefore, according to the present embodiment, even if the first FPC 70 is pulled up and down, the contact pads 73 and 74 of 1299224 are in contact with the driven contacts 33a and 43a of the first and second contacts 30 and 40, and the first active. Contacts 34a, 44a. Therefore, even if an FPC (not shown) provided with a connection pad is connected under the front end portion, the reliability of the contact is not lowered, and a relay connector 10 having a large degree of connection freedom and excellent versatility is obtained. Further, since the lower portion 28 is pushed out than the upper portion 27, it is easy to position the first FPC 70 when it is inserted into the outer casing 20, and the connection workability is further improved. The second embodiment can be attached to the printed circuit board as shown in Figs. 6 and 17 and is suitable for the case of the rear lock type connector 1 1 . The rear locking connector 1 1 refers to the FPC insertion position in the housing and the mounting position of the operating lever to the connector on the opposite side. In the casing 20 according to the present embodiment, as shown in Fig. 7B, the upper portion 27 and the lower portion 27 are protruded from both side edges of the opening portion 21a (not shown) to be inserted into the FPC. In particular, the upper portion 27 is located outwardly from the lower portion 28, and similarly to the first embodiment, it is possible to prevent the FPC from being pulled up and down. ® and the 'contact member 90' is composed of a conductive leaf spring material having a substantially n-shape on the front side. That is, the upper side portion 9 2 ' extends from both sides of the upper end portion of the joint portion 91, and the lower side portion 9 3 extends from both sides of the lower end portion. An active contact 92a is formed on one end side of the upper side portion 92, and an operation portion 92b is provided on the other end side. The one end side of the lower side portion 93 is provided with a locking claw 93a, and the other end side is provided with a fulcrum portion 93b. . Further, among the upper edge portions of the lower side portion 93, the driven contact 94 extends from the vicinity of the lower end portion of the connecting portion 9 so as to face the active contact 92a. -15 - 1299224 Then, the contact member 90 is biased into the casing 20 by press-fitting into the press groove 25 provided in the outer casing 20 to be stopped. At this time, the upper side portion 92 of the aforementioned contact member 90 is supported by the joint portion 9.1 without contacting the outer casing 20. Therefore, by pressing the operating lever 60 attached to the outer casing 20, the pressing portion 69 pushes up the upper edge portion 92 operating portion 92b, and rotates the upper edge portion 9 with the upper end portion of the connecting portion 9 1 as a fulcrum. And the connection pad portion of the FPC (not shown) is held by the driven contact 94 and the active contact 92a and electrically connected. Others are substantially the same as in the first embodiment, and therefore, the same reference numerals will be given to the same portions as Φ, and the description thereof will be omitted. The connector according to the present invention can also be applied to connectors other than the above-described relay connector and rear lock connector.
