携帯電話やＣＣＤカメラ等に使用されるコネクタは、狭ピッチで極薄（所謂軽薄短小）であり、１つのタイプは主にハウジングとコンタクトとを備え、ハウジングにＦＰＣを挿入し、コンタクトの接触部に接触させる構造のもの（所謂、ノンＺＩＦタイプ）やまた違うタイプとしては主にハウジングとコンタクトとスライダーとを備え、ハウジングとスライダーとでＦＰＣを挟持する構造のもの（所謂、ＺＩＦタイプとピアノタッチタイプ）がある。ハウジングとスライダーとでＦＰＣを保持する方法には、色々考えられるが、中でもハウジングにＦＰＣを挿入した後にスライダーを挿入しＦＰＣをコンタクトに押しつける構造のものが多い。また、客先の仕様や狭ピッチを図るためには、前記コンタクトの接続部を前記ハウジングの嵌合口側に配置しなければならないこともある。
ハウジングには、コンタクトが挿入される所要数の挿入孔が設けられるとともにＦＰＣが挿入される嵌合口が設けられている。
コンタクトは主にＦＰＣと接触する接触部と基板等に接続する接続部とハウジングに固定される固定部とを備えている。このコンタクトは、圧入等によってハウジングに固定されている。
下記にＺＩＦタイプとしての特許文献１（実開平６−６０９８３号）とピアノタッチタイプとしての特許文献２（特開平１３−２５７０２０号）、を例示する。また、ＦＦＣをロックする構造として、特許文献３（実開平６−８２７８３号）を例示する。
例えば、ゼロインサーションフォース構造としては、実開平６−６０９８３号がある。実開平６−６０９８３号の要約によると、その目的は、電子機器や通信機器内の狭いスペースに使用されるスライダー付プリント基板用コネクタに関するものであり、その構成は、コネクタのスライダーの両側端部にそのスライダーが挿入されるハウジングへの挿入ガイドとして手前側が固定されたＵ字形状のアーム部を形成し、そのＵ字形状のアーム部の開放端側に凸部を設けるとともに、Ｕ字形状のアーム部の開放端が挿入方向から目視できるように切欠部を設け、ハウジングの両側端部にはスライダーの凸部が係合する傾斜面を有する突出部を設け、スライダーをフレキシブル・プリント基板の接続端子部とともにハウジングに挿入されるとき、当該スライダーの凸部がハウジングの傾斜面を有する突出部を乗り越えることにより、そのＵ字形状のアーム部の開放端が一時的に外側に広げられ、かつ挿入完了時にその開放端が正常位置に復帰するようにしたコネクタが開示されている。所謂、ピアノタッチ構造としては、特開平１３−２５７０２０号に、コネクタのコンタクトとＦＰＣ叉はＦＦＣのパターンとの位置合わせを確実に行うことを目的とし、該文献２には、ＦＰＣ叉はＦＦＣが挿入される開口側の、コネクタの端子ブロックの各コンタクト間の稜線上に突起を列設して、端子ブロックにＦＰＣ叉はＦＦＣを挿入した後に、スライダを移動させることによってＦＰＣ叉はＦＦＣを前記コンタクトに押圧させ、前記スライダでＦＰＣ叉はＦＦＣをコンタクトに押しつけ電気接続させる際に、この突起がＦＰＣ又叉はＦＦＣのパターン間の凹部に入ることにより、コネクタのコンタクトとＦＰＣ叉はＦＦＣのパターンとの位置合わせを確実に行うものが開示されている。フレキシブルフラットケーブルをロックする構造として、実開平６−８２７８３号に、フレキシブルケーブルの裏面にリジットな補強板が取り付けられているフラットケーブルでも容易にスライダーの爪に係止させることを目的とし、該文献３にはコンタクトピンを内装し、フラットケーブルを差し込む嵌合空間を形成したハウジングの嵌合空間内に、スライダーを挿抜自在に且つ抜き出し時に外側に回動可能に取り付け、前記嵌合空間にフラットケーブルを差し込んでからスライダーを嵌合空間に押し込むと、フラットケーブルがコンタクトピンに電気的に接続されるコネクタにおいて、前記スライダーのフラットケーブル当接面に、フレキシブルケーブルの裏面に補強板があてがわれたフラットケーブルのフレキシブルケーブル及び補強板に形成された係止部に挿入係止される係止突子を突設したものが開示されている。 Connectors used for cellular phones, CCD cameras, and the like are narrow pitch and extremely thin (so-called light thin short), and one type mainly includes a housing and a contact, an FPC is inserted into the housing, and a contact portion of the contact A structure in which the FPC is held between the housing and the slider (so-called ZIF type and piano touch). Type). There are various methods for holding the FPC between the housing and the slider. However, there are many methods in which the FPC is inserted into the housing and then the slider is inserted and the FPC is pressed against the contact. In addition, in order to achieve customer specifications and narrow pitches, the contact connection portion may have to be arranged on the fitting port side of the housing.
The housing is provided with a required number of insertion holes into which the contacts are inserted and a fitting port into which the FPC is inserted.
The contact mainly includes a contact portion that comes into contact with the FPC, a connection portion that is connected to a substrate or the like, and a fixed portion that is fixed to the housing. This contact is fixed to the housing by press fitting or the like.
Examples of Patent Document 1 (Japanese Utility Model Publication No. 6-60983) as a ZIF type and Patent Document 2 (Japanese Patent Laid-Open No. 13-257020) as a piano touch type are shown below. Further, Patent Document 3 (Japanese Utility Model Publication No. 6-82783) is exemplified as a structure for locking the FFC.
For example, Japanese Utility Model Publication No. 6-60983 is available as a zero insertion force structure. According to the summary of Japanese Utility Model Laid-Open No. 6-60983, the object is related to a connector for a printed circuit board with a slider used in a narrow space in an electronic device or a communication device. A U-shaped arm portion fixed on the front side is formed as an insertion guide to the housing into which the slider is inserted, and a convex portion is provided on the open end side of the U-shaped arm portion. A notch is provided so that the open end of the arm can be seen from the insertion direction, and a protruding part having an inclined surface that engages the convex part of the slider is provided on both side ends of the housing, and the slider is connected to the flexible printed circuit board. When the slider is inserted into the housing together with the terminal portion, the protruding portion of the slider gets over the protruding portion having the inclined surface of the housing. U-shaped open end of the arm portion of the shape is expanded outwardly temporarily and connector open end upon completion of insertion was made to return to the normal position is disclosed. The so-called piano touch structure is disclosed in Japanese Patent Application Laid-Open No. 13-257020 for the purpose of surely aligning the contact of the connector with the FPC or FFC pattern. Projections are arranged on the ridge lines between the contacts of the connector terminal block on the opening side to be inserted, and after inserting the FPC or FFC into the terminal block, the slider is moved to move the FPC or FFC to the above-mentioned position. When the FPC or FFC is pressed against the contact by the slider and electrically connected to the contact by the slider, this protrusion enters the recess between the FPC or FFC pattern, so that the connector contact and the FPC or FFC pattern A device that reliably aligns the position is disclosed. As a structure for locking a flexible flat cable, Japanese Utility Model Laid-Open No. 6-82783 aims to easily lock a flat cable having a rigid reinforcing plate attached to the back surface of the flexible cable with a slider claw. 3, a contact pin is built in, and a slider is mounted in the fitting space of the housing in which a flat cable is inserted into the fitting space. In the connector where the flat cable is electrically connected to the contact pin when the slider is pushed into the mating space, the reinforcing plate is applied to the flat cable abutment surface of the slider and the back surface of the flexible cable. Flexible cable and reinforcement of flat cable Those which projects a locking cam which is inserted and locked is disclosed in the locking portion formed on.

近年では、客先の仕様によって、４〜１０芯と言った少芯数の要求も増えてきている。ＦＰＣの挿入力は小さい方が良いが、ＦＰＣの保持力は大きい方がよい。このようにＦＰＣの挿入力と保持力には相反することが要求されている。上述した所謂ノンＺＩＦタイプでは、ＦＰＣの挿入力と保持力は、前記コンタクトの接触圧（力）によって決まる。即ち、ＦＰＣの保持力は、コンタクトの芯数にコンタクト１芯当たりの接触圧を乗じた力になる。客先からの保持力５Ｎという要求に対して、１０芯以下では、５Ｎという保持力を確保することができず、ＦＰＣが抜けてしまい接続不良になると言った解決すべき課題があった。
また、上述したＺＩＦタイプの即ち、前記ＦＰＣを前記ハウジングに挿入した後に前記スライダーで前記ＦＰＣを前記コンタクトへ押しつけるものでも、スライダーを挿入した分の初期値が上がるだけで、依然としてコンタクトの接触圧の影響が大きく、客先からの保持力５Ｎという要求に対して、１０芯以下では、５Ｎという保持力を確保することができず、ＦＰＣが抜けてしまい接続不良になると言った課題を解決出来なかった。
なお、文献３のように、フレキシブルケーブルの係止部に突設したスライダーの係止突子を挿入係止されるものでも、スライダーの挿入方向とフレキシブルケーブルの挿入方向が同一のため、依然として、コンタクトの接触圧の影響が大きく、客先からの保持力５Ｎという要求に対して、１０芯以下では、５Ｎという保持力を確保することができず、ＦＰＣが抜けてしまい接続不良になると言った課題を解決出来なかった。 In recent years, demands for a small number of cores, such as 4 to 10 cores, have been increasing according to customer specifications. The FPC insertion force should be small, but the FPC retention force should be large. As described above, it is required that the insertion force and the holding force of the FPC conflict with each other. In the so-called non-ZIF type described above, the insertion force and holding force of the FPC are determined by the contact pressure (force) of the contact. That is, the holding force of the FPC is a force obtained by multiplying the number of contacts by the contact pressure per contact. In response to a customer's request for a holding force of 5N, there was a problem to be solved that a holding force of 5N could not be secured if the number of cores was 10 or less, and the FPC was lost, resulting in poor connection.
Further, even if the above-mentioned ZIF type, that is, the FPC is inserted into the housing and then the FPC is pressed against the contact by the slider, the initial value of the amount of insertion of the slider only increases, and the contact pressure of the contact still remains. The impact is so great that, with respect to the customer's requirement of 5N holding power, if it is 10 cores or less, the holding power of 5N cannot be secured, and the problem that the FPC will come off and connection failure will not be solved. It was.
In addition, even in the case of inserting and locking the slider locking protrusion protruding from the locking portion of the flexible cable as in Reference 3, the insertion direction of the slider and the insertion direction of the flexible cable are the same. The contact pressure of the contact is large, and in response to the customer's request for a holding force of 5N, a holding force of 5N cannot be secured if the core is 10 cores or less, and the FPC will come off, resulting in poor connection. The problem could not be solved.

文献２と文献３とを組み合わせて、文献３のように、文献２に示した所謂ピアノタッチタイプのものに、ＦＰＣに係止部とスライダーに係止突子とを設けたロック構造にすると、ＦＰＣの挿入方向とスライダーの回転方向が違うために芯数が少なくてもＦＰＣの保持力は確保できるが、スライダーには弾性がないので無理にＦＰＣを保持力以上の力で引っ張るとスライダー若しくはＦＰＣが破損してしまう。また、ＦＰＣがこじられる場合には、ＦＰＣを挿入方向と反対方向に引っ張るというよりは、斜め上方へ引っ張るのが一般的であるが、この場合にはスライダーの回転方向と同方向になるため、要求された保持力を得られないことがあった。 Combining literature 2 and literature 3, as in literature 3, the so-called piano touch type shown in literature 2, with a locking structure in which a locking portion and a locking protrusion on the slider are provided on the FPC, Since the insertion direction of the FPC and the rotation direction of the slider are different, the holding force of the FPC can be secured even if the number of cores is small. However, since the slider is not elastic, if the FPC is forcibly pulled with a force greater than the holding force, the slider or FPC Will be damaged. In addition, when the FPC is twisted, it is common to pull the FPC obliquely upward rather than pulling it in the direction opposite to the insertion direction, but in this case, since it is the same direction as the rotation direction of the slider, The required holding force could not be obtained.

そこで、本出願人は、少芯数のコネクタでも、要求されたＦＰＣの保持力を確保することができ、接続不良にも繋がらないコネクタとして、特願２００２−３７３４０３を提案している。この特願２００２−３７３４０３で、ＦＰＣと着脱自在に嵌合するコネクタであって、ＦＰＣと接触する接触部を有する所要数のコンタクトと、このコンタクトが保持・固定されるとともにＦＰＣが挿入される嵌合口を有するハウジングとを備えるコネクタにおいて、ＦＰＣに係止部を設け、係止部と係合する係合部を有するロック部材をハウジングに装着し、ロック部材の係合部をＦＰＣの係止部に係合させることによりＦＰＣがハウジングから抜けないようにするコネクタを提案している。
しかしながら、本出願人が行った上記提案のようなロック構造では、ロック部材の係合部がＦＰＣの係止部に係合した際に、前記係合部の先端がＲ形状をしているため、Ｒ形状部分が前記係止部にかかっているので、ロック部材が外れ易く、保持力が４Ｎしかもたないといった課題があった。 Therefore, the present applicant has proposed Japanese Patent Application No. 2002-373403 as a connector that can secure the required FPC holding force even with a connector with a small number of cores and does not lead to poor connection. In this Japanese Patent Application No. 2002-373403, a connector that is detachably fitted to an FPC, a required number of contacts having a contact portion that comes into contact with the FPC, and a fitting in which the FPC is inserted while holding and fixing the contact. In a connector including a housing having a joint, a locking portion is provided on the FPC, a lock member having an engaging portion that engages with the locking portion is mounted on the housing, and the engaging portion of the lock member is used as the locking portion of the FPC. A connector that prevents the FPC from coming out of the housing by being engaged with the connector is proposed.
However, in the lock structure such as the above proposal made by the present applicant, when the engaging portion of the lock member is engaged with the engaging portion of the FPC, the tip of the engaging portion has an R shape. Since the R-shaped portion is applied to the locking portion, there is a problem that the lock member is easily detached and the holding force is only 4N.

本発明は、このような従来の問題点に鑑みてなされたもので、少芯数のコネクタでも、要求されたＦＰＣの保持力を確保することができ、接続不良にも繋がらないコネクタを提供せんとするものである。 The present invention has been made in view of the above-described conventional problems, and even with a connector with a small number of cores, the required FPC retention force can be secured, and a connector that does not lead to poor connection is not provided.

The contact portion 30, the elastic portion 40, the fulcrum portion 38, and the connection portion 34 are arranged in a substantially U shape. The connection portion 34 is a surface mount type (SMT) as in the case of the first contact 14, but may be a dip type.

前記支点部３８と前記弾性部４０と前記押受部３２とは、第一コンタクト１４と同様に、前記ＦＰＣ２２が挿入された際に、前記回動部材１８の押圧部５０が前記第二コンタクト１６の押受部３２と延設部４２との間で回動すると、前記押受部３２が押圧部５０によって押し上げられることで前記第二コンタクト１６の支点部３８を支点にし、前記第二コンタクト１６の弾性部５０が前記接触部３０側に傾くことによって、前記接触部３０が前記ＦＰＣ２２側に押圧される。前記支点部３８と前記弾性部４０と前記押受部３２の大きさや形状は、このような作用を果たすために、適宜設計されている。また、前記第二コンタクト１６の押受部３２の先端に突出部４４を設け、回動部材１８の押圧部５０を回動させるとき、前記回動部材１８の係止孔４８に係合させることで、回動部材１８の回動に対する強い反発力に対抗し、回動部材１８の中央部が図１（Ａ）の矢印「ロ」方向に膨れてしまうことを防ぐようにすることが望ましいが、ピッチの狭小化による前記回動部材１８の強度を考慮すると、第一コンタクト１４及び第二コンタクト１６の内、第一コンタクト１４に設けておけば、十分である。前記突出部４４の大きさは、このような役割を果たすことが出来れば如何なる大きさでもよく、回動部材１８の係止孔４８に引っ掛かる程度に適宜設計する。 As with the first contact 14, the fulcrum 38, the elastic portion 40, and the pressing portion 32 are configured so that when the FPC 22 is inserted, the pressing portion 50 of the rotating member 18 is the second contact 16. When the support portion 32 and the extension portion 42 are rotated, the support portion 32 is pushed up by the pressing portion 50, so that the fulcrum portion 38 of the second contact 16 serves as a fulcrum, and the second contact 16. When the elastic part 50 is inclined toward the contact part 30, the contact part 30 is pressed toward the FPC 22 side. The sizes and shapes of the fulcrum part 38, the elastic part 40, and the pressing part 32 are appropriately designed in order to achieve such an action. Further, a protrusion 44 is provided at the tip of the pressing portion 32 of the second contact 16, and when the pressing portion 50 of the rotating member 18 is rotated, it is engaged with the locking hole 48 of the rotating member 18. in, against the strong repulsive force against the rotation of the rotating member 18, it is desirable that the central portion of the rotating member 18 so as prevent you blistering arrow "b" direction in FIG. 1 (a) Considering the strength of the rotating member 18 due to the narrowing of the pitch, it is sufficient to provide the first contact 14 among the first contact 14 and the second contact 16 . The size of the protrusion 44 may be any size as long as it can fulfill such a role, and is appropriately designed to be caught in the locking hole 48 of the rotating member 18.

第一コンタクト１４及び第二コンタクト１６ともに上述したような略倒Ｈ字形状にしたが、例えば、第一コンタクト１４に代えて、図示はしないが、一方のコンタクトの支点部から延設した方向に設けたＦＰＣとの接触部を削除した略逆ｈ字形状にしたコンタクトを使用してもよい。
また、前記第二コンタクト１６も同様に、図示はしないが、主にＦＰＣ２２と接触する接触部と基板に接続する接続部とハウジングに固定する固定部と前記接触部と前記接続部との間に設けられた弾性部及び支点部と前記弾性部から延設された押受部を備えた、略逆ｈ字形状のものでもよく、前記接触部と前記弾性部と前記支点部と前記接続部とが略コ字形状に配置されている。 Although both the first contact 14 and the second contact 16 have a substantially inverted H shape as described above, for example, in place of the first contact 14, although not illustrated, in a direction extending from the fulcrum portion of one contact You may use the contact made into the substantially reverse h character shape which deleted the contact part with provided FPC.
Similarly, although not shown, the second contact 16 is mainly between a contact portion that contacts the FPC 22, a connection portion that is connected to the substrate, a fixing portion that is fixed to the housing, and the contact portion and the connection portion. A substantially inverted h-shape having an elastic part and a fulcrum part provided and a pressing part extending from the elastic part may be used, and the contact part, the elastic part, the fulcrum part, and the connection part, Are arranged in a substantially U-shape.

最後に、回動部材１８について説明する。この回動部材１８は電気絶縁性のプラスチックであり、公知技術の射出成形によって製作され、この材質としては寸法安定性や加工性やコスト等を考慮して適宜選択するが、一般的にはポリブチレンテレフタレート（ＰＢＴ）やポリアミド（６６ＰＡ、４６ＰＡ）や液晶ポリマー（ＬＣＰ）やポリカーボネート（ＰＣ）やこれらの合成材料を挙げることができる。前記回動部材１８は主にハウジング１２の嵌合口２４と反対側に回動可能に装着される軸４６部分と前記第一コンタクト１４及び前記第二コンタクト１６の押受部３２を押圧する押圧部５０と前記第一コンタクト１４及び前記第二コンタクト１６の突出部４４が係合する係止孔４８とを備えている。前記軸４６は、回動部材１８を回動するための支点であり、ハウジング１２の長手方向両側に回動部材１８が回動可能に適宜装着されている。また、長手方向両側には、前記第一コンタクト１４及び前記第二コンタクト１６の押受部３２を押圧した際に回動部材１８が高さ（図面の上）方向に持ち上がらないようにするためにハウジング１２と係合するロック部が設けられている。ロック部の形状や大きさ等は、ハウジング１２に係合できれば如何なるものでもよく、上述の役割やコネクタ１０の大きさや強度等を考慮して適宜設計する。 Finally, the rotating member 18 will be described. The rotating member 18 is an electrically insulating plastic and is manufactured by a known technique of injection molding. This material is appropriately selected in consideration of dimensional stability, workability, cost, etc. Examples include butylene terephthalate (PBT), polyamide (66PA, 46PA), liquid crystal polymer (LCP), polycarbonate (PC), and synthetic materials thereof. The rotating member 18 mainly includes a shaft 46 portion rotatably mounted on the opposite side of the fitting port 24 of the housing 12 and a pressing portion that presses the pressing portion 32 of the first contact 14 and the second contact 16. 50 and a locking hole 48 with which the projection 44 of the first contact 14 and the second contact 16 engages. The shaft 46 is a fulcrum for rotating the rotation member 18, and the rotation member 18 is appropriately mounted on both sides in the longitudinal direction of the housing 12 so as to be rotatable. Further, on both sides in the longitudinal direction, the rotation member 18 is prevented from being lifted in the height (upper drawing) direction when the pressing portions 32 of the first contact 14 and the second contact 16 are pressed. A lock portion that engages with the housing 12 is provided.

また、前記回動部材１８を回動した際に、回動部材１８の回動に対する反発力が強く、回動部材の中央部が図１（Ａ）の矢印「ロ」方向に膨れてしまうことを防ぐようにする為に、前記第一コンタクト１４の突出部４４が係合する係止孔４８が別個独立に設けられている。前記係止孔４８を別個独立に設けることで、回動部材１８の強度アップや回動時の変形を防止している。
上述した前記回動部材１８は前記ハウジング１２の嵌合口２４と反対側（一方のコンタクトの接続部側）に回動自在に装着されている。 The pressing portion 50 of the rotating member 18 is a portion that is pressed against the pressing portion 32 of the first contact 14 and the second contact 16 , and the shape thereof is preferably an elongated shape. In this embodiment, an elliptical shape is used. I am doing. By thus forming an elliptical shape, the rotating member 18 is rotated in the direction of the arrow “A” as shown in FIG. 1A, and between the pressing portion 32 and the connecting portion 34 of the first contact 14. By rotating, the pressing portion 32 of the first contact 14 is lifted by the change in the size of the pressing portion 50, and the FPC 22 is pressed against the contact portion 30 side of the first contact 14. As the shape of the pressing portion 50, the pressing portion 32 of the first contact 14 can be rotated between the pressing portion 32 and the connecting portion 34, and the pressing portion 32 of the first contact 14 is pushed up by the difference in size such as the major axis and the minor axis. Anything can be used.
Further, upon rotating the rotating member 18, stronger repulsive force against rotation of the rotating member 18, the central portion of the rotating member resulting in blisters arrow "B" direction in FIG. 1 (A) In order to prevent this, a locking hole 48 with which the protrusion 44 of the first contact 14 engages is provided separately. By providing the locking holes 48 separately and independently, the strength of the rotating member 18 is prevented from being increased and deformation at the time of rotation is prevented.
The rotating member 18 described above is rotatably mounted on the side opposite to the fitting port 24 of the housing 12 (the connection portion side of one contact).
