柔軟電纜之前端部近傍之近前側，使該平形柔軟電纜之前 端部從近前側斜上方朝向開口部，使1對之導引用突部接 觸在上述1對之導引面。藉此，限制1對之導引用突部之 前端之朝向幅度方向（與***方向正交之方向）之變位，以 達成該平形柔軟電纜之幅度方向之定位。 然後，使 1對之導引用突部沿著1對之導引面，將 平形柔軟電纜之前端部更進一步導引到接受部側 時，1對之導引用突部從導引面落下到接受部，成為 藉由接受部接受平形柔軟電纜之前端部。然後，若使 平形柔軟電纜對電路板之表面成為大致平行時，1對 之導引用突部受到接受部掛在導引之階梯面，使平形 柔軟電纜即使被拉到近前側亦不會脫落。藉此達成平 形柔軟電纜之***方向之定位，在此狀態使蓋子閉合 時，可將平形柔軟電纜固定在電氣連接器。 但是，在上述方式之電氣連接器中，平形柔軟電纜幾乎 不撓曲，成為使其前端部從近前側斜上方朝向開口部。因 此，在1對之導引用突部接觸在對應之導引面之狀態，自 該導引用突部對導引面，由於平形柔軟電纜之撓曲產生之 按壓力幾乎不作用。因此，其後使1對之導引用突部沿著 6 312/發明說明書(補件)/93-06/93109220 1241755 導引面，將平形柔軟電纜之前端部更進一步的導引到接受 部側，使該平形柔軟電纜之前端部落下至接受部時，平形 柔軟電纟覽從撓曲狀態返回之量變小。 在此情況，因為幾乎不會產生使平形柔軟電纜之前端部 落下到接受部時之喀喱音（裝著音），所以作業者不容易明 白是否確實定位，會有不能良好進行定位之情況。 伴隨近年來之電子機器（個人電腦等）之小型化，最好是 使電氣連接器小型化和薄型化，但在小型（薄型）之電氣連 接器中，平形柔軟電纜之定位特別困難。 本發明係針對此種背景所完成，其目的是提供可以更良 好進行安裝平形柔軟電纜時之定位之電氣連接器。 【發明内容】 本發明係關於電氣連接器（1 )，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 器包含有：接受部（9 )，從上述電路板側接受被***到上述 電氣連接器之平形柔軟電纜之前端部；階梯面（2 9 7 )，用來 從電纜***方向（D )近前側限制被突設在上述接受部所接 受之平形柔軟電纜之前端部之兩側緣之1對導引用突部， 藉以對該平形柔軟電纜進行定位；1對之第1導引面 ( 2 9 3 )，對於上述接受部，在電纜***方向近前側，經由上 述階梯面被配置成高於上述接受部，與上述電路板之表面 大致平行地延伸，用來從上述電路板側導引朝向上述接受 部之平形柔軟電纜之上述1對之導引用突部；及1對之第 2導引面（2 9 5 )，對於上述1對之第1導引面，在上述電路 7 312/發明說明書(補件)/93-06/93丨09220 1241755 板之相反側，隔開一定間隔的面對，從上述電路板之相反 側導引朝向上述接受部之平形柔軟電纜之上述1對之導引 用突部使其朝向上述接受部。 另外，括弧内之英數字表示後面所述之實施形態之對應 構成元件等，但是本發明無意被解釋成只限於該實施形 態。以下與此項相同。 依據此構成，在將平形柔軟電纜安裝到該電氣連接器 時，以平形柔軟電纜之導引用突部通過第1導引面和第2 導引面之間之空間（導引凹部）内之方式，成為使平形柔軟 電纜之前端部從近前側大致水平地（與電路板之表面大致 平行的）朝向接受部側。通常，因為電路板之表面和第1 導引面之距離較短，所以摘取平形柔軟電纜之前端部近傍 之近前側，若不從其摘取部份使近前側（前端部之相反側） 之部份大幅撓曲到上方（電路板之相反側）時，要使平形柔 軟電纜之前端部從近前側大致水平地朝向接受部側會有困 難。在此情況，在導引凹部内被導引之平形柔軟電纜之前 端部之導引用突部，接觸在第1導引面，從該導引用突部 對第1導引面，作用有因平形柔軟電纜之撓曲而產生之按 壓力。 因此，其後，使導引用突部沿著第1導引面，將平形柔 軟電纜之前端部導引到接受部側，當該平形柔軟電纜之前 端部從第1導引面落下至接受部時，因為平形柔軟電纜之 撓曲量變大，所以從撓曲狀態返回之平形柔軟電纜之前端 部，對接受部強力地碰撞。在此情況，當平形柔軟電纜之 8 312/發明說明書(補件)/93-06/93109220 1241755 前端部碰撞接受部時，因為產生喀喱音，所以作業者容易 明白平形柔軟電纜之定位之達成。因此，可以更良好地進 行定位。 在比較小型（薄型）之電氣連接器中，特別是平形柔軟電 纜之定位會有困難，所以上述之效果更高。 另，構成1對之第2導引面之構件（突緣構件）因為被配 置在電氣連接器之前端上部之容易看見之位置，所以使平 形柔軟電纜之前端部朝向導引凹部時，若以突緣構件作為 目標，可以更容易地導引平形柔軟電纜。 最好使上述1對之第2導引面（2 9 5 )對於藉由上述階梯 面（2 9 7 )而被定位之平形柔軟電纜（7 )之上述1對之導引用 突部（7 1 )，被配置在偏移至電纜***方向近前側之位置。 依據此構成，1對之第2導引面對於藉由階梯面而被定 位之平形柔軟電纜之1對之導引用突部，因為偏移至電纜 ***方向近前側，所以藉由接受部所接受到之平形柔軟電 纜之1對之導引用突部，成為可以從上方（電路板之相反側） 辨識。因此，作業者可以辨識平形柔軟電纜之定位之確實 達成。 最好使上述1對之第1導引面（2 9 3 )具有延伸部，係使 其電纜***方向近前側之端部超過與上述1對之第2導引 面（2 9 5 )面對之位置，延伸至電纜***方向（D )近前側。 依據此構成，因為1對之第1導引面之電纜***方向近 前側之端部具有不與1對之第2導引面面對之區域，所以 在俯視電路板之平面圖中，第1導引面之前端部向上方開 9 312/發明說明書(補件)/93-06/93109220 1241755 放。因此，使平形柔軟電纜之前端部朝向導引凹部時，即 使在其前端部之位置稍微偏移至上方（電路板之相反側）之 情況下，第2導引面亦可以經由不與第1導引面面對之部 份（缺口）導引至導引凹部（第1導引面側），所以平形柔軟 電纜之幅度方向（與電纜***方向正交之方向）之定位可以 更容易。 亦可為包含有構成上述一對之第2導引面（295)之1對 突緣構件2 9 4之構成。 在此情況，亦可在上述突緣構件之電纜***方向近前側 形成有缺口（296)，藉由該缺口，在上述1對之第1導引面 之電纜***方向近前側之端部，形成不與上述1對之第2 導引面面對之區域。 本發明之上述及其他目的，特徵及效果，藉由參照附圖 之下述實施形態之說明當可更加明白。 【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之外觀 構成示意圖，顯示使蓋子4開啟之狀態。圖1 ( a )係表示平 面圖，圖1 ( b )係表示前視圖，圖1 ( c )係表示右側視圖。但

connector for connecting a flat flexible cable such as FPC (Flexible Printe, etc.) to a circuit board [prior art] The conventional electrical connector has a housing, There are openings for inserting cables, and a plurality of flat flexible cables inserted through the openings are held by the casing to achieve electrical connection to the cables (see, for example, Japanese Patent Laid-Open No. 11 1 and Japanese Unexamined Patent Publication No. 8-1 0 0 9 40). In this type of electrical connector, an opening space is formed by opening a cover of a relatively rotatable housing to form a crimping position into which a flat flexible cable is inserted. People who can insert a non-insertion flexible cable into this insertion space (refer to, for example, Japanese Publication No. 2 0 0-2 1 4 7 8). This type of electrical connector is a so-called Insertion Force type. When the thin insert is closed, a plurality of connection parts are crimped to the flat flexible cable, and the air connection is made. In addition, such an electrical connector includes, for example, a flat flexible end portion that accepts insertion from an opening portion from below (on a circuit board side), and a flat flexible mouth portion that is inserted in such a manner that the front end portion is received by the receiving portion. The flat flexible cable is guided at the front end, and then the cover is closed, so that the flat flexible electrical connector can be connected. 312 / Invention Manual (Supplement) / 93-06 / 93109220 d Circuit) ο Press into the flat flexible joint. The flat flexible -329619 is installed under multiple connection parts to make the flat flexible QIF special open ZIF ( After Zero, the cover is used to reach the electrical receiving part. Before the flexible cable, the flexible cable is pulled from the open to the crimping position. The cable is fixed in the 5 1241755. A pair of guide surfaces are provided on the front side for guiding a pair of guide protrusions protruding from both side edges of the front end of the flat flexible cable inserted into the receiving portion from below. The surface is arranged one step higher than the receiving portion. When the flat flexible cable is mounted on the electrical connector, the near end of the front end of the flat flexible cable is taken off, so that the front end of the flat flexible cable is diagonally above the front side Toward the opening, the guide protrusion of one pair is brought into contact with the guide surface of the above one pair. As a result, the change in the width direction (direction orthogonal to the insertion direction) of the front end of the guide protrusion of one pair is restricted. Bit to reach the level Positioning of the flexible cable in the direction of amplitude. Then, with one pair of guiding protrusions along the guiding surface of one pair, when the front end of the flat flexible cable is further guided to the receiving portion side, one pair of guiding protrusions The part falls from the guide surface to the receiving part, and becomes the front end of the flat flexible cable received by the receiving part. Then, when the flat flexible cable is made substantially parallel to the surface of the circuit board, one pair of guide protrusions receives the receiving part Hanging on the stepped surface of the guide, so that the flat flexible cable will not fall off even if it is pulled to the near side. This achieves the positioning of the flat flexible cable in the insertion direction. When the cover is closed in this state, the flat flexible cable can be fixed at Electrical connector. However, in the electrical connector of the above-mentioned method, the flat flexible cable is hardly flexed, and its front end portion is inclined obliquely from the front side toward the opening portion. Therefore, the guide protrusions in one pair are in contact with each other. In the state of the guide surface, the pressing force generated by the deflection of the flat flexible cable from the guide projection to the guide surface has almost no effect. Therefore, one pair of guides is subsequently guided. Use the protrusion along the guide surface of 6 312 / Invention Specification (Supplement) / 93-06 / 93109220 1241755 to further guide the front end of the flat flexible cable to the side of the receiving portion, so that the front end of the flat flexible cable is tribal When going down to the receiving section, the amount of return of the flat flexible electrical view from the flexed state becomes small. In this case, there is almost no click sound (loading sound) when the front end of the flat flexible cable goes down to the receiving section. Therefore, it is not easy for the operator to understand whether the positioning is accurate or not. With the miniaturization of electronic devices (personal computers, etc.) in recent years, it is desirable to reduce the size and thickness of electrical connectors. In small (thin) electrical connectors, the positioning of flat flexible cables is particularly difficult. The present invention has been made in view of such a background, and an object thereof is to provide an electrical connector which can better perform positioning when installing a flat flexible cable. SUMMARY OF THE INVENTION The present invention relates to an electrical connector (1), which is assembled on a circuit board (8) for electrically connecting a flat flexible cable (7) to the circuit board. The electrical connector includes a receiving portion (9) for receiving from the circuit board side the front end of the flat flexible cable inserted into the electrical connector; and a stepped surface (2 7 7) for receiving the cable from the direction of insertion (D ) Near the front side, a pair of guide protrusions protruding from both sides of the front end of the flat flexible cable accepted by the receiving section is used to position the flat flexible cable; one pair of the first guide surface ( 2 9 3), the receiving portion is located near the receiving portion near the cable insertion direction, is higher than the receiving portion via the stepped surface, and extends substantially parallel to the surface of the circuit board for guiding from the circuit board side The above-mentioned one pair of guide reference protrusions of the flat flexible cable facing the above-mentioned receiving portion; and the second guide surface (2 9 5) of the one pair, for the first guide surface of the one pair, in the above circuit 7 312 / Specification of the Invention (Supplement) / 93-06 / 93 丨 09220 1241755 The opposite side of the board, facing at a certain interval, and guided from the opposite side of the circuit board toward the above-mentioned one pair of flat flexible cables of the receiving part Guide the protrusions towards the above Reception Department. In addition, the alphanumeric characters in parentheses indicate corresponding 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 is the same as this. According to this configuration, when the flat flexible cable is attached to the electrical connector, the guide protrusion of the flat flexible cable passes through the space (guide recess) between the first guide surface and the second guide surface. So that the front end portion of the flat flexible cable is approximately horizontal (approximately parallel to the surface of the circuit board) from the near side toward the receiving portion side. Generally, because the distance between the surface of the circuit board and the first guide surface is short, remove the near front side of the front end of the flat flexible cable. If you do not remove it from the front side (the opposite side of the front end) It is difficult to make the front end of the flat flexible cable from the near side to the receiving side when the part is flexed to the upper side (the opposite side of the circuit board). In this case, the guide protrusion on the front end of the flat flexible cable guided in the guide recess contacts the first guide surface, and the guide protrusion projects a flat shape on the first guide surface. Pressing force caused by flex of flexible cable. Therefore, after that, guide the guide protrusion along the first guide surface to guide the front end portion of the flat flexible cable to the receiving portion side, and when the front end portion of the flat flexible cable falls from the first guide surface to the receiving portion At this time, since the amount of flex of the flat flexible cable becomes large, the front end portion of the flat flexible cable returned from the flexed state strongly collides with the receiving portion. In this case, when the flat flexible cable 8 312 / Invention Specification (Supplement) / 93-06 / 93109220 1241755 hits the front end of the receiving section, a click sound is generated, so the operator can easily understand the positioning of the flat flexible cable. . Therefore, positioning can be performed more favorably. In relatively small (thin) electrical connectors, the positioning of flat flexible cables can be difficult, so the above effects are even higher. In addition, since the member (flange member) constituting the second guide surface of the pair is arranged at an easily visible position at the upper part of the front end of the electrical connector, when the front end of the flat flexible cable faces the guide recess, The flange member is targeted to make it easier to guide a flat flexible cable. Preferably, the second guide surface (2 9 5) of the above-mentioned one pair guides the projection (7 1) of the above-mentioned one pair of the flat flexible cable (7) positioned by the above-mentioned stepped surface (2 7 7). ) Is placed at a position offset to the front side of the cable insertion direction. According to this configuration, the guide protrusions of the one pair and the second guide surface of the one pair of flat flexible cables positioned by the stepped surface are shifted to the front side of the cable insertion direction, so they are accepted by the receiving portion. The flat lead of the pair of flat flexible cables can be identified from above (opposite to the circuit board). Therefore, the operator can recognize that the positioning of the flat flexible cable is indeed achieved. It is preferable that the first guide surface (2 9 3) of the above-mentioned one pair has an extension portion such that the end near the front side of the cable insertion direction exceeds the second guide surface (2 9 5) of the above-mentioned one pair. Position to the front of the cable insertion direction (D). According to this configuration, since the end near the cable insertion direction of the first guide surface of the pair has a region that does not face the second guide surface of the pair, the first guide The front end of the leading surface is opened upward 9 312 / Invention Specification (Supplement) / 93-06 / 93109220 1241755. Therefore, when the front end of the flat flexible cable is directed toward the guide recess, even when the position of the front end portion is slightly shifted to the upper side (opposite to the circuit board), the second guide surface can pass through the first guide surface. The part (notch) facing the guide surface is guided to the guide recess (first guide surface side), so the positioning of the width direction (direction orthogonal to the cable insertion direction) of the flat flexible cable can be easier. It may be a structure including a pair of flange members 2 94 which constitute the second guide surface (295) of the pair. In this case, a notch (296) may be formed near the cable insertion direction of the flange member, and the notch may be formed at the end near the front side of the cable insertion direction of the first pair of first guide surfaces.

The electrical connector 1 is provided with a housing 2 made of synthetic resin, and includes, for example, an upper plate portion 10 312 / Invention Specification (Supplement) / 93-06 / 93109220 1241755 2 1, a lower plate portion 2 2 and left and right side plate portions 2 3 The interior space drawn by the district 2 4. 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 7 such as an FPC (Flexible Printed Circuit) inserted into the housing 2 through an insertion direction port from the front. The left and right side plate portions 23 of the casing 2 are respectively formed with press-fitting holes 25 extending from the front end to the rear, and the respective press-fitting holes 25 are, for example, pressurized metal reinforcing fins 3 from the front. Each of the reinforcing fins 3 is made, for example, by punching a metal plate, and includes: a press-in portion 31, which is press-fitted into the press-in hole 2 5; and a main body portion 32, which is removed from the housing 2 in a mounted state. The side plate portion 23 projects forward. The upper end edge of the main body portion 32 extends to the same height as the side plate portion 23 of the case 2 (see FIG. 1 (c)). At the upper end of the rear edge of the main body portion 32, a protruding portion 3 2 1 is formed to protrude to the rear. The protruding portion 32 is spaced apart from the protruding portion 211 protruding to the front from the upper edge of the front edge of the side plate portion 23 of the casing 2 in a state where the reinforcing fin 3 is pressed into the casing 2 from the front. Face each other. At the lower edge of the press-fitting portion 31, for example, two lock projections 34 are formed to lock the press-fitting portion 31 pressed into the press-fitting hole 25 from the front. The casing 2 has, for example, a shape in which the lower plate portion 22 protrudes more forward than the upper plate portion 21 and the side plate portion 23, whereby the front end portion of the upper side of the casing 2 (by a pair of reinforcing fins 3) The main body portion 32 is a part of the clip) forming an opening portion 26 for inserting the front end portion of the flat flexible cable 7. The openings 26 are opened and closed by, for example, a synthetic resin cover 4 that can be rotated around a metal rotating shaft 41 that extends coaxially in the left-right direction. 11 312 / Invention Manual (Supplement) / 93-06 / 93109220 1241755 Each rotation axis 41 is protruded from the left and right end surfaces of the cover 4 in the left-right direction. The rear edge of the main body portion 32 of the reinforcing flap 3 and the front edge of the side plate portion 23 facing it, and the protruding portions 3 2 1 and 2 1 1 protruding from the main body portion 32 and the side plate portion 23 respectively. The enclosed space is formed with an insertion hole 35 through which the rotating shaft 41 of the cover 4 is inserted. The cover 4 is rotatably installed by inserting each rotation shaft 41 of the cover 4 into the corresponding insertion hole 35. The housing 2 is formed with a plurality of connection portions 5 and 6 (for example, a total of 80 pieces), and is crimped to the inserted flat flexible cable 7 to achieve electrical connection between the flat flexible cable 7 and the circuit board so as to face the opening portion. 2 6 way is maintained. Each of the connection portions 5 and 6 is made, for example, by punching a metal plate. The plurality of connecting portions 5 and 6 are arranged parallel to each other at equal intervals (for example, about 0.3 leg pitch) in the left-right direction in a plan view. In the present embodiment, the plurality of connection portions 5 and 6 include, for example, two types of the first connection portion 5 pressed into the housing 2 from the front, and the second connection portion 6 pressed into the housing 2 from the rear. The first and second connecting 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, but the first connection portion 5 may be pressed into the housing 2 from the rear, and the second connection portion 6 is from the front. The structure in which the square is pressed into the housing 2 may be a structure in which the first connection portion 5 and the second connection portion 6 are pressed in from the same direction (front or rear). From the left and right sides of the front end of the lower plate portion 2 2 of the housing 2, the guide portions 29 project forward, and are used to guide the front end of the flat flexible cable 7 when the flat flexible cable 7 is installed in the electrical connector 1. unit. Each guide portion 29, Example 12 312 / Invention specification (Supplement) / 93-06 / 93109220 1241755 If formed to have a height substantially the same as that of the side plate portion 23 of the housing 2, an upper portion of the inner surface 291 is formed at The guide recesses 2 9 2 extending straight in the front-to-rear direction are used to guide the front end of the flat flexible cable 7. The width (length in the left-right direction) of the flat flexible cable 7 mounted on the electrical connector 1 is approximately the same as the distance between the inner surfaces 2 9 1 of the two guide portions 29. On the left and right side edges of the front end of the flat flexible cable 7, guide reference protrusions 71 are respectively formed to guide the inner bottom surface of the front guide guide recess 2 9 2 through the guide recess 2 9 2 to form a first guide. The lead surface 2 9 3 is used to guide the guide protrusion 71 of the flat flexible cable 7 in the guide recess 2 9 2 from below. In addition, a second guide surface 295 is formed on the upper surface of the guide recess 292, and is formed by the lower surface of the flange member 2 9 4 protruding from the upper end edge of the guide portion 29 to the inside (left-right direction) for guiding from above. The projection 71 is guided by the guide of the flat flexible cable 7 in the guide recess 2 9 2. The first guide surface 2 9 3 and the second guide surface 2 9 5 face each other with a certain interval (for example, about 0.7 coffee). The length in the left-right direction of the front side of the cover 4 (opposite to the rotation axis 41) is approximately the same as the distance between the front ends of the flange members 2 9 4 of the two guide portions 29. Therefore, when the lid 4 is closed, the lower surface of the front end of the lid 4 is received by the first guide surface 293, and the guide recess 292 is blocked by the lid 4. At the front ends of the left and right sides of the lid 4, engaging claws 43 are respectively protruding to lock the lid 4 in a closed state. When the cover 4 is turned from the open state to the closed state, after the engaging claws 4 3 collide with the flange member 2 9 4, the elastic claws of the respective parts 4 3, 2 9 4 are deformed to thereby engage the claws 4 3 from Below the flange member 2 9 4. Thereby, the engaging claw portion 4 3 is connected to 13 312 / Invention specification (Supplement) / 93-06 / 93109220 1241755 is closed under the flange member 294 (the second guide surface 295), and is used to lock the cover 4 in the closed position. status. The left and right end portions of the rear side of the cover 4 (the side of the rotating shaft 41) are projecting portions 42 protruding in the left-right direction than the left and right end portions of the front side of the cover 4. The length in the left-right direction of the rear side of the cover 4 (the portion provided with the protruding portion 42) is approximately the same as the distance between a pair of reinforcing fins 3. When the cover 4 is closed, the opening 2 6 is covered by the cover 4 as a whole. cover. Figures 2 and 3 are cross-sectional views taken along line A-A of Figure 1 (a).

A front end portion of the fixing piece portion 51 projects to the front of the lower plate portion 22 of the housing 2 'and a lead portion 54 is formed at a front end portion thereof to project downward (on the circuit board 8 side). Soldering is performed by soldering 312 on the assembly surface of the lead portion 54 and the circuit board 8 / invention supplementary) / 93-06 / 93109220 15 1241755, and the periphery of the contact portion is covered with solder. The first connection portion 5 is fixed to the circuit board 8 to electrically connect the first connection portion 5 to the circuit board 8. In addition, at the rear end of the fixing piece portion 51, a press-fitting portion 55 protruding to the rear is formed, and the press-fitting portion 55 is pushed into the press-fitting hole 281 formed in the housing 2 from the front to press the first The connection portion 5 is fixed to the casing 2. On the upper edge of the press-fitting part 5 5, for example, a locking protrusion 5 5 1 is formed, so that the press-fitting part 55 pressed into the press-fitting hole 281 from the front is stopped at the press-fitting hole 281 ° at the cover 4 A groove 4 41 is formed at a position corresponding to the front end of the lid contacting portion 52, and is used to prevent the interference of the lid pressing portion 52 when the lid 4 is opened and closed. In this groove 441, a contact portion 45 is formed for contacting the front end of the lid pressing portion 52 from below. The peripheral surface (contact surface 4 5 1) on the side of the lid pressing portion 5 of the contact portion 4 5 is a peripheral surface having a slightly circular cross section, and the contact portion 45 that rotates with the opening and closing of the lid 4 is contacted with The lid pressing portion 5 2 of the contact surface 4 5 1 can be smoothly rotated. A protruding portion 5 2 1 is formed at the front end of the lid pressing portion 5 2 and projects downward along the contact surface 451 of the facing contact portion 45. Referring to FIGS. 4 and 5, the second connection portion 6 includes, for example, a substantially rectangular fixing piece portion 61 that is disposed at an end portion behind the internal space 24 of the housing 2 and has a height that substantially matches the height of the internal space 24. ; The movable piece portion 63, which extends from the front end of the lower portion of the fixed piece portion 61 to the front along the bottom of the internal space 24; and the press-in portion 65, which extends straight from the front end of the upper portion of the fixed piece portion 61 to the upper plate Department 2 1 before. From the front end of the movable piece section 63, a flat flexible cable (the so-called lower contact type) which is crimped from the bottom of 16 312 / Invention Specification (Supplement) / 93-06 / 93109220 1241755 to the insertion space 2 7 ) The contact portion 6 6 projects upward. By inserting the second connection portion 6 into the inner space 2 4 of the housing 2 from behind, the press-in portion 65 is pressed into the press-in hole 2 8 2 formed in the housing 2, thereby fixing the second connection portion 6. On the housing 2. At the lower edge of the press-in portion 65, for example, a stopper projection 6 51 is formed to stop the press-in portion 65 of the second connection portion 6 which is pressed into the press-in hole 282 from the rear. A recess 4 4 2 is formed at a position of the cover 4 corresponding to the front end of the press-fitting portion 65, and is used to prevent interference of the press-fitting portion 65 when the cover 4 is opened and closed. A lead portion 64 that protrudes downward (on the circuit board 8 side) is formed at the lower end of the rear end of the fixed piece portion 61, and the contact portion of the solder portion on the assembly surface of the lead portion 64 and the circuit board 8 is formed. Soldering, the periphery of this contact part is covered with solder. Thereby, the second connection portion 6 is fixed to the circuit board 8, and the second connection portion 6 is electrically connected to the circuit board 8. In this embodiment, since the lead portion 54 of the first connection portion 5 projects downward from the front end portion of the case 2 and the lead portion 64 of the second connection portion 6 projects downward from the rear end portion of the case 2, it is from below When the electrical connector 1 is viewed, the lead portions 5 4 and 64 of each of the connecting portions 5 and 6 are arranged in a staggered manner along the left-right direction. Thereby, even when the pitch between the first connection portion 5 and the second connection portion 6 becomes narrow, a sufficient space can be secured for soldering the lead portions 54 and 64 to the circuit board 8, Therefore, it is possible to prevent the solder formed around each of the lead portions 5 4 and 64 from being short-circuited due to interference with each other, and the assembling density can be improved. As shown in Fig. 2 (a) and Fig. 4 (a), when the cover 4 is closed, 17 3 12 / Invention Manual (Supplement) / 93-06 / 93109220 1241755 is opened in the receiving section 9 (Contact 66 of each connection portion 5 and 6) and the cover 4 to form an insertion space 2 7 having a height equal to or greater than the thickness of the flat shape 1 and opening the guide 2 9 2 blocked by the cover 4 (refer to FIG. 2). (b) and Figure 4 (b)). When the flat flexible cable 7 is mounted on the electrical connector 1, as shown in FIG. 4 (b), the front end of the flat flexible 7 is approximately horizontal from the front side (with the circuit board) with the cover 4 opened. The table of 8 is parallel) in the insertion direction D toward the guide recess 2 9 2 side, so that a pair of projections 7 1 are in contact with the corresponding first guide surfaces 2 9 3 (see and FIG. 5 (a)). Thereby, the direction of the width direction (horizontal direction orthogonal to the insertion direction D) of the guide protrusions 71 of one pair is used to achieve the positioning of the width direction of the flat flexible cable 7. In this embodiment, 296 is formed at the front end portion of the flange member 294, and the front end portion of the first guide surface 293 has a region that does not face the second guide 3. That is, the first guide surface 293 has an extension portion, and an end portion near the front side in the insertion direction D extends beyond the surface of the second guide surface 295 to the front side in the cable insertion direction D. Therefore, when the front end portion of the flat first guide surface 293 is opened upward through the notch 296 so that the front end portion of the flat flexible cable 7 faces the guide recess portion 2 9 2 side, the position of the front end portion is slightly offset from the guide recess portion 2 9 2. Moving to the top and bottom, the guide protrusion 71 can be guided to the recess 2 9 2 (the first guide surface 2 9 3 side) through the notch 296, so the positioning of the flat flexible cable in the degree direction becomes easier. Then, guide the guide protrusion 71 through the guide recess 2 9 2, step 312 / Invention specification (Supplement) / 93-06 / 93109220 section 56, cable 7 guide recess Figure 2 (b) The approximate surface of the flexible cable Guide figure 3 (a) The front end is displaced, and the gap q 295 is seen from its cable position. With this, even if the situation reaches the width of the guide 7 "Flat 18 1241755 The front end of the flexible cable 7 is further guided to the rear (deep side), the guide protrusion 7 1 is guided from the first guide surface 2 9 3 It drops to the receiving part 9 and becomes the front end part which receives the flat flexible cable 7 by the receiving part 9. Then, as shown in FIG. 3 (b) and FIG. 5 (b), if the surface of the flat flexible electrical view 7 is substantially parallel to the surface of the circuit board 8, the guide protrusion 71 is hung on the receiving section 9 and the first guide The stepped surface 2 9 7 of the surface 2 9 3 does not fall off even if the flat flexible cable 7 is moved closer to the front side. Thereby, it is used to achieve the positioning of the insertion direction D of the flat flexible cable 7. In this embodiment, since the distance between the surface of the circuit board 8 and the first guide surface 293 is short (for example, about 1.5 legs), the front end of the flat flexible cable 7 is taken away from the near front side. When the portion near the front side (opposite side of the front end portion) is largely deflected upward from the extracted portion, the front end portion of the flat flexible cable 7 should be approximately horizontally from the front side toward the guide recess 2 9 2 side. Difficulties. In this case, the guiding protrusion 71 leading to the front end of the flat flexible cable 7 guided into the guiding recess 2 9 2 contacts the first guiding surface 293, and from this guiding protrusion 7 to 1 The guide surface 2 9 3 acts as a pressing force due to the elbow of the flat flexible electrical system 7. Therefore, thereafter, the guide protrusion 71 is guided along the first guide surface 2 9 3 to guide the front end portion of the flat flexible cable 7 to the receiving portion 9 side, and the front end portion of the flat flexible cable 7 is guided from the first guide portion. When the lead surface 2 9 3 is dropped to the receiving portion 9, the amount of deflection of the flat flexible cable 7 increases, so the front end of the flat flexible cable 7 returned from the flexed state strongly collides with the receiving portion 9. In this case, when the front end portion of the flat flexible cable 7 collides with the receiving portion 9, a click sound is generated (installation sound), so the operator can easily understand the flat flexible cable 19 312 / Invention Specification (Supplement) / 93- 06/93109220 1241755 The positioning of cable 7 was reached. Therefore, positioning can be performed more favorably. In a smaller (thin) type electrical connector like the electrical connector 1 of this embodiment, the positioning of the flat flexible cable 7 is particularly difficult, so the above-mentioned effect is higher. Since the flange member 2 9 4 is arranged at an easily visible position on the upper part of the front end of the electrical connector 1, when the front end portion of the flat flexible cable 7 faces the guide recess 2 9 2, if the flange member 2 9 4 is used The aim is to make it easier to guide the flat flexible cable 7. In addition, in this embodiment, the pair of second guide surfaces 2 9 5 are arranged so as to face only the corresponding first guide surfaces 2 9 3 and not to face the receiving portion 9. That is, a pair of second guide surfaces 2 9 5 and a pair of guide reference projections 7 1 of the flat flexible cable 7 positioned by the stepped surface 2 9 7 are arranged to be offset to the cable insertion direction D Near the front side. As a result, notch portions 91 are formed at the left and right ends of the receiving portion 9 (behind the stepped surface 2 97) in a planar view and facing upward (see FIG. 1 (a)). The pair of guiding and guiding portions 71 of the flat flexible cable 7 received can be identified from above through the notch 91. Therefore, the operator can recognize that the positioning of the flat flexible cable 7 is actually achieved, so that the positioning can be performed better. When the cover 4 is closed from the state shown in FIGS. 3 (b) and 5 (b), the flat flexible cable 7 can be fixed to the electrical connector 1. At this time, because the front end of the flat flexible cable 7 is inserted into the insertion space 27, when the cover 4 is to be closed, the rear end of the rotating cover 4 comes into contact with the flat flexible cable 7. Then, when the cover 4 is further rotated, the first connecting portion 5 and the second connection 20 are connected via the flat flexible cable 7 through the rear edge of the cover 4 312 / Instruction Manual (Supplement) / 93-06 / 93109220 1241755 The movable piece portions 5 3 and 6 3 of the portion 6 are pressed downward and elastically deformed. Then, as shown in FIGS. 3 (c) and 5 (c), when the lid 4 is closed, the elastically deformed movable piece portions 5 3 and 63 of the first connection portion 5 and the second connection portion 6 return to their original positions. status. In this state, the upper surface of the front end of the flat flexible cable 7 is in contact with the lower surface of the cover 4. A pressure portion 30 is formed at the end edge behind the lower surface of the lid 4 so as to protrude downward. As shown in FIGS. 3 (c) and 5 (c), in the state where the cover 4 is closed, the flat flexible cable 7 is firmly fixed at the first end because the pressing portion 30 presses the front end of the flat flexible cable 7 from above. 1 连接 部 5 和 第二 连接 部 6。 The connection portion 5 and the second connection portion 6. The present invention is not limited to the contents of the above embodiments, and various changes can be made within the scope of the patent application. For example, the receiving portion 9 for receiving the front end portion of the flat flexible cable 7 is not limited to the front portion of the contact portion 5 6 and 6 6 of the first connection portion 5 and the second connection portion 6. The first guide surface 2 9 3 constitutes the receiving surface of the lower stage. The first guide surface 293 and the second guide surface 295 are not limited to those composed of the same member (guide portion 2 9), and may be constituted by different members, respectively. The first connection portion 5 and the second connection portion 6 are not limited to the so-called lower contact type which is crimped to the flat flexible cable 7 from below, but may also be the so-called upper contact type which is crimped to the flat flexible cable 7 from above. .
