Abstract
Description
この発明は、小型の電子機器に実装される電子部品やプリント基板間を接続するためのプリント基板の接続構造とその接続用のＦＰＣ及び電子機器に関するものである。 The present invention relates to an electronic component mounted on a small electronic device and a printed circuit board connection structure for connecting printed circuit boards, an FPC for the connection, and an electronic device.
近年の電子機器、例えば、デジタルカメラや携帯電話等は小型化が加速している。こうした電子機器に実装される電子部品やプリント基板間を接続するには、平型柔軟ケーブル（以下、ＦＰＣ）が使用されている。 Recent electronic devices such as digital cameras and mobile phones have been increasingly miniaturized. A flat flexible cable (hereinafter referred to as FPC) is used to connect between electronic components and printed circuit boards mounted on such electronic devices.
また、ＦＰＣのように屈曲性を持って接続する手段として、ＦＦＣ（Ｆｌｅｘｉｂｌｅ Ｆｌａｔ Ｃａｂｌｅ）も良く知られている。ＦＦＣは導体を平行に並べて両側端子以外を絶縁体で覆ってＦＰＣのように曲げて配線することができる。 As a means for connecting with flexibility like FPC, FFC (Flexible Flat Cable) is also well known. The FFC can be wired by arranging conductors in parallel, covering other than both side terminals with an insulator, and bending it like an FPC.
このＦＰＣは、柔軟性のある樹脂からなる基板の表面に銅箔等の導電性物質を所望のパターンで配置したもので、該導電性のパターンによってコネクタ端子等を介して供給された電気信号を各部に供給するようになっている。 In this FPC, a conductive material such as copper foil is arranged in a desired pattern on the surface of a substrate made of a flexible resin, and an electric signal supplied via a connector terminal or the like by the conductive pattern is used. It is designed to be supplied to each part.
このようなＦＰＣでは、例えば、
「（１）．配線途中に部品を配置する。
（２）．配線を途中で入れ替える。
（３）．電源／ＧＮＤがコネクタで連続する複数ラインに設定されている。」
等の場合に、接続途中では複数ラインを分離せずに１つの太いラインにまとめてインピーダンスを低下させる、などができる。
In such an FPC, for example,
“(1). Parts are arranged in the middle of wiring.
(2). Replace the wiring in the middle.
(3). The power supply / GND is set to a plurality of continuous lines at the connector. "
In such a case, it is possible to reduce the impedance by combining the lines into one thick line without separating the lines during the connection.
しかし、ＦＰＣではコネクタへの接続方向を間違えると機器が正常に作動できなくなることも考えられる。 However, in FPC, if the connection direction to the connector is wrong, the device may not be able to operate normally.
また、上述したようなデジタルカメラや携帯電話等のように小さい機器では、多くの端子全体にわたって均一な力を与えるために金属部材を用いた大型化コネクタよりも、モールド部材が主の小型化コネクタを複数用いた方がトータル容量として有利となる場合がある。このような小型化コネクタとして複数のＦＰＣを用いることで、ＦＰＣで接続する部品にピン数が少ないコネクタが用いられたメーカーの汎用品が選択できる。また、汎用品であれば、同じピン数の複数備品の購入となるのでコスト的に有利である。更に、同じ構造のコネクタを採用することで信頼性も全く同じように考えることができる。 Also, in small devices such as the digital cameras and mobile phones as described above, the molded member is mainly a miniaturized connector rather than a large-sized connector using a metal member in order to give a uniform force over many terminals. It may be advantageous to use a plurality of the total capacity. By using a plurality of FPCs as such miniaturized connectors, it is possible to select a general-purpose product of a manufacturer in which a connector having a small number of pins is used as a component to be connected by FPC. In addition, a general-purpose product is advantageous in terms of cost because it requires the purchase of a plurality of equipment with the same number of pins. Furthermore, the reliability can be considered in exactly the same way by adopting a connector having the same structure.
しかし、一般的に使用されるコネクタに対応したＦＰＣの両端部に形成される端子形状は似ているため、ＦＰＣの端子を基板の接続部へ挿入する際に、作業者がＦＰＣの挿入先を誤って挿入してしまうことがある。この場合、装置が動作しなかったり、最悪の場合装置が破損するという問題がある。この問題を解決するため、特殊な形状のコネクタとＦＰＣの組み合わせにより、誤った挿入が出来ないようにする誤挿入防止用のコネクタの技術が既に知られている。 However, since the terminal shapes formed at both ends of the FPC corresponding to the commonly used connector are similar, when inserting the FPC terminal into the connection portion of the board, the operator selects the FPC insertion destination. It may be inserted by mistake. In this case, there is a problem that the device does not operate or the device is damaged in the worst case. In order to solve this problem, there has already been known a technique of a connector for preventing erroneous insertion that prevents erroneous insertion by combining a specially shaped connector and an FPC.
この誤挿入防止用のコネクタの技術としては、例えば、一対一組のＦＰＣの側縁に突起部を設けて、この突起部によりＦＰＣが基板の接続部に接続されるのを防止するようにした技術が知られている（例えば、特許文献１参照）。 As a technique of the connector for preventing erroneous insertion, for example, a protrusion is provided on the side edge of a pair of FPCs so that the FPC is prevented from being connected to the connection part of the board by the protrusion. A technique is known (see, for example, Patent Document 1).
しかし、今までの誤挿入防止用のコネクタでは、汎用性が少ないためラインナップが限られていることから、コネクタの仕様に合わせて周辺部品を設計する必要があるなど、設計の自由度が狭められるという問題があった。また、特殊形状であることからコストも高いという問題があった。 However, the conventional connectors for preventing incorrect insertion have limited versatility, so the lineup is limited. Therefore, it is necessary to design peripheral parts according to the connector specifications, and the degree of design freedom is narrowed. There was a problem. Moreover, since it was a special shape, there existed a problem that cost was also high.
そこで、本発明は、従来の課題に鑑みてなされたものであり、汎用的なコネクタを使用した場合でも、ＦＰＣの誤挿入を防止できるプリント基板の接続構造とその接続用のＦＰＣ及び電子機器を提供することを目的とするものである。 Therefore, the present invention has been made in view of the conventional problems, and there is provided a printed circuit board connection structure capable of preventing erroneous insertion of an FPC even when a general-purpose connector is used, and an FPC and an electronic device for the connection. It is intended to provide.
この目的を達成するため、この発明は、第１のプリント基板の上に設けられた第１配線用コネクタ部と、第２のプリント基板の上に設けられた第２配線用コネクタ部と、前記第１配線用コネクタ部と第２配線用コネクタ部を接続するＦＰＣを備え、前記配線用コネクタ部は前記ＦＰＣが挿入される方向と直交する方向に配置された同一構造で同一ピン数からなる１組の配線用コネクタをそれぞれ有するプリント基板の配線構造であって、前記ＦＰＣは、前記第１のプリント基板上の一方の配線用コネクタと前記第２のプリント基板上の一方の配線用コネクタを接続する第１配線部と、前記第１のプリント基板上の他方の配線用コネクタと前記第２のプリント基板上の他方の配線用コネクタを接続する第２配線部と、該第１の配線部と第２の配線部を一体とするように接続する接続部とを備え、
前記ＦＰＣが正しい向きで前記配線用コネクタに接続されたときは、前記第１のプリント基板と第２のプリント基板のいずれか一方に配置された突起部が干渉を回避し、該ＦＰＣが正しくない向きで前記配線用コネクタに接続されたときは前記突起部に対して前記接続部が干渉するように、前記突起部および前記接続部の外形形状が設定されていることを特徴とする。
To achieve this object, the present invention provides a first wiring connector portion provided on a first printed board, a second wiring connector portion provided on a second printed board, An FPC for connecting the first wiring connector portion and the second wiring connector portion is provided, and the wiring connector portion has the same structure and the same number of pins arranged in a direction orthogonal to the direction in which the FPC is inserted.

A first wiring portion that connects the other wiring connector on the first printed circuit board and the other wiring connector on the second printed circuit board, and the first wiring portion, Second arrangement Parts and a connecting portion connecting to the integrally,
When the FPC is connected to the wiring connector in the correct orientation, the protrusions disposed on either the first printed circuit board or the second printed circuit board avoid interference, and the FPC is incorrect. The external shape of the protrusion and the connection portion is set so that the connection portion interferes with the protrusion when connected to the wiring connector in a direction.
また、プリント基板の接続用のＦＰＣはプリント基板の配線構造に用いたＦＰＣを有し、電子機器はこのＦＰＣを用いて接続されたプリント基板を有する。 Further, the FPC for connecting the printed circuit board has the FPC used for the wiring structure of the printed circuit board, and the electronic device has the printed circuit board connected by using this FPC.
この構成によれば、汎用的なコネクタを使用した場合においても、ＦＰＣの誤挿入を防止できる。 According to this configuration, even when a general-purpose connector is used, erroneous insertion of the FPC can be prevented.

[作用]
このような構成のプリント基板の接続構造の作用を説明する。
As shown in FIG. 1A, the connection terminal portions 10b and 11b at one end of the first and second FPC portions 10 and 11 are connected to the FPC connection connector substrates 4 and 5 of the first printed circuit board 1, respectively. The connection terminal portions 10a and 11a at the other ends of the first and second FPC portions 10 and 11 are connected to the FPC connection connector substrates 6 and 7 of the second printed circuit board 2, respectively, thereby the first and second printed circuit boards. 1 and 2 are normally connected.
[Action]
The operation of the printed circuit board connection structure having such a configuration will be described.
図３（ａ）に示したように、ＦＰＣ３の第１，第２ＦＰＣ部１０，１１の接続端子部１０ａ，１１ａを第２のプリント基板２のＦＰＣ接続用コネクタ基板６，７に接続使用とした場合、ＦＰＣ３の接続規制用連結部１２が第２のプリント基板２の接続規制突部９に当接して、接続端子部１０ａ，１１ａがＦＰＣ接続用コネクタ基板６，７の接続口６ａ，７ａに挿入接続されるのは阻止される。 As shown in FIG. 3A, the connection terminal portions 10a and 11a of the first and second FPC portions 10 and 11 of the FPC 3 are connected to the FPC connection connector substrates 6 and 7 of the second printed circuit board 2. In this case, the connection restricting connecting portion 12 of the FPC 3 abuts on the connection restricting protrusion 9 of the second printed circuit board 2, and the connection terminal portions 10 a and 11 a are connected to the connection ports 6 a and 7 a of the FPC connecting connector substrates 6 and 7. Insertion and connection are prevented.
一方、図３（ｂ）に示したように、ＦＰＣ３の第１，第２ＦＰＣ部１０，１１の接続端子部１０ｂ，１１ｂを第２のプリント基板２のＦＰＣ接続用コネクタ基板６，７に接続使用とした場合、ＦＰＣ３の接続規制用連結部１２は接続規制突部９に当接することがないので、接続端子部１０ｂ，１１ｂはＦＰＣ接続用コネクタ基板６，７の接続口６ａ，７ａに挿入接続される。この状態では、接続端子部１０ａ，１１ａは図１Ａに示したように第１のプリント基板１に設けたＦＰＣ接続用コネクタ基板４，５のＦＰＣ接続口４ａ，５ａに挿入接続できる。 On the other hand, as shown in FIG. 3B, the connection terminal portions 10b and 11b of the first and second FPC portions 10 and 11 of the FPC 3 are connected to the FPC connection connector substrates 6 and 7 of the second printed circuit board 2. In this case, since the connection restricting connecting portion 12 of the FPC 3 does not contact the connection restricting protrusion 9, the connection terminal portions 10b and 11b are inserted and connected to the connection ports 6a and 7a of the FPC connecting connector boards 6 and 7, respectively. Is done. In this state, the connection terminal portions 10a and 11a can be inserted and connected to the FPC connection ports 4a and 5a of the FPC connection connector boards 4 and 5 provided on the first printed circuit board 1 as shown in FIG. 1A.
このように図１，図１Ａは、一対一組とするＦＰＣ（第１，第２ＦＰＣ部１０，１１）を、突起部（接続規制突部９）が実装された第２のプリント基板２のＦＰＣ接続用コネクタ基板６，７にＺＩＦ（Zero Insertion Force socket）、ＮｏｎＺＩＦコネクタ接続する構成を示したものである。 As described above, FIG. 1 and FIG. 1A show the FPC (first and second FPC portions 10 and 11) as a pair, and the FPC of the second printed circuit board 2 on which the protruding portion (connection restricting protruding portion 9) is mounted. The structure which connects ZIF (Zero Insertion Force socket) and NonZIF connector to the connector board | substrates 6 and 7 for a connection is shown.
この図１，図１Ａは二つのＦＰＣ（第１，第２ＦＰＣ部１０，１１）を接続して一対一組としたＦＰＣ３を示したものである。ＦＰＣ３の端からある一定の距離Ａを離して接続されている。もう一方の端からある一定の距離Ｂだけ離して接続されている。図示したように距離Ａ＜距離Ｂである。接続部に関しては、ＦＰＣと同一材料であるが、テープ等の外部的に貼り付けを行い接続しても良い。 FIG. 1 and FIG. 1A show an FPC 3 in which two FPCs (first and second FPC units 10 and 11) are connected to form a pair. They are connected at a certain distance A from the end of the FPC 3. The other end is connected at a certain distance B. As shown, distance A <distance B. The connection portion is made of the same material as that of the FPC, but may be connected by attaching it externally such as a tape.
また、ＦＰＣ接続用コネクタ基板６，７の端からある一定の距離Ｃだけ離れた面を移動規制面として有するチップ部品が移動規制突部（突起部）９として実装されている。距離Ｃは、Ｃ＞Ａを成り立つように実装されている。チップ部品であるＦＰＣ接続用コネクタ基板６，７の高さに関しては、特に規定はしない。 Further, a chip component having a surface that is a certain distance C away from the ends of the FPC connection connector boards 6 and 7 as a movement restricting surface is mounted as a movement restricting protrusion (projection) 9. The distance C is mounted so that C> A. The height of the FPC connector boards 6 and 7 that are chip parts is not particularly specified.
尚、ＺＩＦとは、Zero Insertion Force socketの略で、ＣＰＵの脱着を行うソケットの機構のひとつで、ソケットの脇に取り付けられたレバーの操作によってＣＰＵチップの抜き差しが行える機構のことである。ＣＰＵが入出力を行う接触部分はピンと呼ばれるが、最近の高性能なＣＰＵは有するピンの数が数百本にのぼる。これらを通常のソケットに挿入したり取り外したりするには、ある程度の力を入れる必要があり、装着が甘くて接触不良を起こしたり、取り外しの際にピンが曲がってしまうといった事態が生じやすい。これをうまく脱着するにはある程度の技術の習熟が必要になる。ＺＩＦソケットでは、ＣＰＵの固定と解放をレバー操作によって行う。レバーを上げてＣＰＵをソケットに挿入し、レバーを元に戻すと、ピンは挟まれて固定され、確実に装着される。取り外す際もレバーを上げてピンを解放すればよい。いずれにしても、ＺＩＦでは抜き差しに力を加える必要がない（Ｚｅｒｏ Ｉｎｓｅｒｔｉｏｎ Ｆｏｒｃｅである）。 ZIF is an abbreviation for Zero Insertion Force socket, which is one of the socket mechanisms for attaching and detaching the CPU. The CPU chip can be inserted and removed by operating a lever attached to the side of the socket. The contact portion where the CPU performs input / output is called a pin, but recent high-performance CPUs have hundreds of pins. In order to insert or remove them from a normal socket, it is necessary to apply a certain amount of force, and it is easy to cause a situation where the mounting is not easy and poor contact occurs, or the pins are bent during removal. A certain level of skill is required to remove and install it. In the ZIF socket, the CPU is fixed and released by operating the lever. When the lever is raised, the CPU is inserted into the socket, and the lever is returned to the original position, the pin is pinched and fixed, and is securely attached. When removing it, you can lift the lever to release the pin. In any case, it is not necessary to apply force to the insertion / extraction in ZIF (Zero Insertion Force).
従って、実施例１では、詳細な図示および説明は省略したが、ＦＰＣ接続用コネクタ基板（配線用コネクタ）４〜７にＺＩＦが用いられている。 Therefore, in the first embodiment, although detailed illustration and description are omitted, ZIF is used for the FPC connection connector boards (wiring connectors) 4 to 7.
以上説明した実施例１では、ＦＰＣ接続用コネクタ基板（配線用コネクタ）４〜７の側面に開口するＦＰＣ接続口４ａ〜７ａを設けて、ＦＰＣ３の第１ＦＰＣ部１０の接続端子部１０ａ，１１ａをＦＰＣ接続用コネクタ基板４，５の側面からＦＰＣ接続口４ａ，５ａに接続し、ＦＰＣ３の第１ＦＰＣ部１０の接続端子部１０ａ，１１ｂをＦＰＣ接続用コネクタ基板６，７の側面から接続口６ａ，７ａに接続することにより、第１，第２のプリント基板１，２を接続するように構成したが、必ずしも接続方向は上述した実施例に限定されるものではない。しかも、実施例１では、ＦＰＣ接続用コネクタ基板（配線用コネクタ）４〜７にＺＩＦコネクタを用いたが必ずしもこれに限定されるものではない。例えば、ＢｔｏＢ（Ｂｏａｒｄ ｔｏ Ｂｏａｒｄ）コネクタを用いて、第１，第２のプリント基板１，２を接続する構成としても良い。尚、ＢｔｏＢコネクタ（ボードtoボードコネクタ）は、周知であるのでその詳細な接続構造の図示および説明は省略する。 In Example 1 demonstrated above, the FPC connection port 4a-7a opened to the side surface of the connector board | substrate (wiring connector) 4-7 for FPC connection is provided, and connection terminal part 10a, 11a of the 1st FPC part 10 of FPC3 is provided. The FPC connection connector boards 4 and 5 are connected to the FPC connection ports 4a and 5a from the side surfaces, and the connection terminal portions 10a and 11b of the first FPC portion 10 of the FPC 3 are connected to the connection ports 6a and 6a from the side surfaces of the FPC connection connector boards 6 and 7, respectively. Although the first and second printed circuit boards 1 and 2 are connected by connecting to 7a, the connection direction is not necessarily limited to the above-described embodiment. Moreover, in the first embodiment, ZIF connectors are used for the FPC connection connector boards (wiring connectors) 4 to 7, but the invention is not necessarily limited thereto. For example, the first and second printed circuit boards 1 and 2 may be connected using a BtoB (Board to Board) connector. Since the BtoB connector (board-to-board connector) is well known, the detailed connection structure is not shown or described.
このＢｔｏＢコネクタを用いた接続構造に用いる構成としては、例えば、図４（ａ），（ｂ），図５に示したような構成としても良い。即ち、図４（ａ），（ｂ），図５に示したように、ＺＩＦコネクタであるＦＰＣ接続用コネクタ基板（配線用コネクタ）４〜７に変えてＢｔｏＢ（Ｂｏａｒｄ ｔｏ Ｂｏａｒｄ）コネクタのソケットであるＦＰＣ接続用コネクタ基板（配線用コネクタ）４Ａ〜７Ａを用いると共に、ＢｔｏＢ用のＦＰＣ３Ａの第１ＦＰＣ部１０ＡにＢｔｏＢ接続用の接続端子部１０ｃ，１０ｄを設け、ＢｔｏＢ用のＦＰＣ３Ａの第２ＦＰＣ部１１ＡにＢｔｏＢ接続用の接続端子部１１ｃ，１１ｄを設けて、ＦＰＣ３ＡでＦＰＣ接続用コネクタ基板（配線用コネクタ）４Ａと６Ａおよび５Ａと７Ａを接続する構成としても良い。 As a configuration used for the connection structure using the BtoB connector, for example, the configurations shown in FIGS. 4A, 4B, and 5 may be used. That is, as shown in FIGS. 4 (a), 4 (b), and 5, a BtoB (Board to Board) connector socket is used instead of the FPC connector board (wiring connector) 4-7 that is a ZIF connector. A certain FPC connection connector board (wiring connector) 4A to 7A is used, and BtoB connection terminal portions 10c and 10d are provided on the first FPC portion 10A of the BtoB FPC 3A, and the second FPC portion 11A of the BtoB FPC 3A. In addition, connection terminal portions 11c and 11d for BtoB connection may be provided to connect the FPC connection connector boards (wiring connectors) 4A and 6A and 5A and 7A with the FPC 3A.
この場合、ＦＰＣ接続用コネクタ基板（配線用コネクタ）４Ａと接続端子部１０ｃとでＺＩＦコネクタが構成されると共に、ＦＰＣ接続用コネクタ基板（配線用コネクタ）６Ａと接続端子部１０ｄとでＺＩＦコネクタが構成される。また、ＦＰＣ接続用コネクタ基板（配線用コネクタ）５Ａと接続端子部１１ｃとでＺＩＦコネクタが構成され、ＦＰＣ接続用コネクタ基板（配線用コネクタ）７Ａと接続端子部１１ｄとでＺＩＦコネクタが構成される。この構成の配置等を以下に説明する。 In this case, the FPC connector board (wiring connector) 4A and the connection terminal portion 10c constitute a ZIF connector, and the FPC connection connector board (wiring connector) 6A and the connection terminal portion 10d constitute a ZIF connector. Composed. Further, the FPC connector board (wiring connector) 5A and the connection terminal portion 11c constitute a ZIF connector, and the FPC connection connector board (wiring connector) 7A and the connection terminal portion 11d constitute a ZIF connector. . The arrangement of this configuration will be described below.
図４（ａ）に示したように、実施例１のＦＰＣ接続用コネクタ基板４，５と同様に第１のプリント基板１にはＢｔｏＢコネクタであるＦＰＣ接続用コネクタ基板（配線用コネクタ）４Ａ，５Ａが近接して設けられ、実施例１のＦＰＣ接続用コネクタ基板（配線用コネクタ）６，７と同様に第２のプリント基板２にはＢｔｏＢコネクタであるＦＰＣ接続用コネクタ基板６Ａ，７Ａが近接して設けられている。そして、ＦＰＣ接続用コネクタ基板４Ａ〜７Ａには、側面ではなく上面に開口するＦＰＣ接続口４ｃ〜７ｃが形成されている。また、第２のプリント基板２には、実施例１と同様に接続規制突部９が設けられている。 As shown in FIG. 4A, the FPC connection connector board (wiring connector) 4A, which is a BtoB connector, is provided on the first printed circuit board 1 in the same manner as the FPC connection connector boards 4 and 5 of the first embodiment. 5A is provided in the vicinity, and FPC connection connector boards 6A and 7A, which are BtoB connectors, are close to the second printed circuit board 2 in the same manner as the FPC connection connector boards (wiring connectors) 6 and 7 of the first embodiment.

Further, the second printed circuit board 2 is provided with a connection restricting protrusion 9 as in the first embodiment.
一方、ＦＰＣ３Ａは上述した実施例１のＦＰＣ３の第１ＦＰＣ部１０，第２ＦＰＣ部１１と同様に平板状の第１ＦＰＣ部１０Ａ，第２ＦＰＣ部１１Ａを有するが、実施例１と異なる構成は平板状の第１ＦＰＣ部１０Ａの両端部に面と直交する方向に突出する接続端子部１０ｃ，１０ｄが設けられ、第２ＦＰＣ部１１Ａの両端部に面と直交する方向に突出する接続端子部１１ｃ，１１ｄが設けられている点である。 On the other hand, the FPC 3A includes the first FPC portion 10A and the second FPC portion 11A that are flat like the first FPC portion 10 and the second FPC portion 11 of the FPC 3 of the first embodiment described above. Connection terminal portions 10c and 10d projecting in a direction orthogonal to the surface are provided at both ends of the first FPC portion 10A, and connection terminal portions 11c and 11d projecting in a direction orthogonal to the surface are provided at both ends of the second FPC portion 11A. This is the point.
また、第１ＦＰＣ部１０Ａ，第２ＦＰＣ部１１Ａは、接続端子部１０ｃ，１１ｃ側の端部近傍の部分がＦＰＣ３の接続規制用連結部（接続部）１２で連結されている。このＦＰＣ３の接続規制用連結部１２は、接続端子部１０ｃ，１１ｃが接続用コネクタ基板６Ａ，７ＡのＦＰＣ接続口６ｃ，７ｃ上に配設されたとき、接続規制突部９上に位置するように設けられている。しかも、図５に示したように接続規制突部９の高さをＥとし、接続用コネクタ基板６Ａ，７Ａの高さをＤとすると、高さ（距離）Ｅは高さ（距離）Ｄよりも高く設定され（高さＥ＞高さＤ）ている。そして、図４（ａ），図５に示したように、接続規制用連結部１２が第２のプリント基板２側に配設されて接続規制突部９に当接した状態では、接続端子部１０ｃ，１１ｃがＦＰＣ接続用コネクタ基板６Ａ，７ＡのＦＰＣ接続口６ｃ，７ｃに挿入されないようになっている。 Further, the first FPC portion 10A and the second FPC portion 11A are connected at the connection terminal portions 10c, 11c side near the end portion by the connection restricting connection portion (connection portion) 12 of the FPC 3. The connection restriction connecting portion 12 of the FPC 3 is positioned on the connection restriction protrusion 9 when the connection terminal portions 10c and 11c are disposed on the FPC connection ports 6c and 7c of the connection connector boards 6A and 7A. Is provided. Moreover, as shown in FIG. 5, when the height of the connection restricting protrusion 9 is E and the height of the connector boards 6A and 7A for connection is D, the height (distance) E is higher than the height (distance) D. Is also set high (height E> height D). As shown in FIGS. 4A and 5, in the state where the connection restricting coupling portion 12 is disposed on the second printed circuit board 2 side and is in contact with the connection restricting protrusion 9, the connection terminal portion. 10c and 11c are not inserted into the FPC connection ports 6c and 7c of the FPC connection connector boards 6A and 7A.
一方、図４（ｂ）に示したように、接続規制用連結部１２が第１のプリント基板１側に配設された状態では、接続規制用連結部１２が接続規制突部９に当接することはない。この状態では、図４（ａ）の接続端子部１０ｃ，１１ｃを図４（ａ）のＦＰＣ接続用コネクタ基板６Ａ，７ＡのＦＰＣ接続口５ｃ，４ｃに挿入接続し、図４（ａ）の接続端子部１０ｄ，１１ｄを図４（ａ）のＦＰＣ接続用コネクタ基板６Ａ，７ＡのＦＰＣ接続口７ｃ，６ｃに挿入接続することができる。そして、この接続により図４（ｂ）のようにＦＰＣ３Ａの第１ＦＰＣ部１０ＡによりＦＰＣ接続用コネクタ基板４Ａ，６Ａが正常に接続され、第２ＦＰＣ部１１ＡによりＦＰＣ接続用コネクタ基板５Ａ，７Ａが正常に接続される。 On the other hand, as shown in FIG. 4B, in the state where the connection restricting connecting portion 12 is disposed on the first printed circuit board 1 side, the connection restricting connecting portion 12 contacts the connection restricting protrusion 9. There is nothing. In this state, the connection terminal portions 10c and 11c of FIG. 4A are inserted and connected to the FPC connection ports 5c and 4c of the FPC connection connector boards 6A and 7A of FIG. 4A, and the connection of FIG. The terminal portions 10d and 11d can be inserted and connected to the FPC connection ports 7c and 6c of the FPC connection connector boards 6A and 7A shown in FIG. As a result of this connection, as shown in FIG. 4B, the FPC connector boards 4A and 6A are normally connected by the first FPC section 10A of the FPC 3A, and the FPC connector boards 5A and 7A are normally connected by the second FPC section 11A. Connected.
上述した実施例１，２では、一対一組の第１，第２ＦＰＣ部１０，１１（又は１０Ａ，１１Ａ）からなるＦＰＣ３（３Ａ）は接続規制用連結部（接続部）１２が直線であるため、第１，第2のプリント基板１，２へのＦＰＣ接続用コネクタ基板（コネクタ）の実装ずれ、ＦＰＣ３の形状の製造公差により接続ができない場合がある。 そこで、第１，第2のプリント基板１，２へのＦＰＣ接続用コネクタ基板（コネクタ）の実装ずれがあっても、接続規制用連結部１２の形状を曲線にすることにより、自由度が増し、ＦＰＣ接続が容易となり解消可能となる。本実施例では、接続規制用連結部１２がＳ字状に形成されている。 In the first and second embodiments described above, the FPC 3 (3A) including the pair of the first and second FPC portions 10 and 11 (or 10A and 11A) has a straight connection restriction connecting portion (connection portion) 12. In some cases, the FPC connection connector board (connector) may not be mounted on the first and second printed circuit boards 1 and 2 and the FPC 3 may have a manufacturing tolerance in shape. Therefore, even if the FPC connection connector board (connector) is not mounted on the first and second printed boards 1 and 2, the degree of freedom is increased by making the shape of the connection restricting coupling portion 12 curved. FPC connection becomes easy and can be eliminated. In this embodiment, the connection restricting coupling portion 12 is formed in an S shape.
この場合、接続規制用連結部１２の材料としては、補強板などの硬い材料を避け、柔軟な材料により構成する。例えば、接続規制用連結部１２にはＦＰＣ３と同一材料を用いているが、接続規制用連結部１２としては柔軟性のある粘着テープ等を用いても良い。 In this case, as a material of the connection restricting coupling portion 12, a hard material such as a reinforcing plate is avoided and the material is constituted by a flexible material. For example, although the same material as that of the FPC 3 is used for the connection restricting connecting portion 12, a flexible adhesive tape or the like may be used as the connection restricting connecting portion 12.
この場合、例えば、図７に示したように構成しても良い。この図７では、第１，第２ＦＰＣ部１０，１１を所定間隔に配置した状態で、第１ＦＰＣ部１０の一端部近傍の部分の一面（図７の第１ＦＰＣ部１０の上面）と第２ＦＰＣ部１１の一端部近傍の部分の一面（図７の第２ＦＰＣ部１１の上面）とに第1の粘着テープ片１２ａの両端部を貼り付ける。また、第１ＦＰＣ部１０の一端部近傍の部分の他面（図７の第１ＦＰＣ部１０の下面）と第２ＦＰＣ部１１の一端部近傍の部分の他面（図７の第２ＦＰＣ部１１の下面）とに第２の粘着テープ片１２ｂの両端部を貼り付ける。そして、第１，第２の粘着テープ片１２ａ，１２ｂの中間部１２ａ１，１２ｂ１を互いに接着させて接続規制用連結部１２とすることにより、第１，第２ＦＰＣ部１０，１１の一端部近傍の部分をテープで外部的に貼り付けを行い接続した構成としている。 In this case, for example, it may be configured as shown in FIG. In FIG. 7, in a state where the first and second FPC units 10 and 11 are arranged at a predetermined interval, one surface near the one end of the first FPC unit 10 (the upper surface of the first FPC unit 10 in FIG. 7) and the second FPC unit The both ends of the 1st adhesive tape piece 12a are affixed on one surface (upper surface of the 2nd FPC part 11 of FIG. 7) of the part of the 11 end part vicinity. Also, the other surface of the first FPC unit 10 near one end (the lower surface of the first FPC unit 10 in FIG. 7) and the other surface of the second FPC unit 11 near the one end (the lower surface of the second FPC unit 11 in FIG. 7). ) And affixing both ends of the second adhesive tape piece 12b. Then, the intermediate portions 12a1 and 12b1 of the first and second adhesive tape pieces 12a and 12b are bonded to each other to form the connection restricting coupling portion 12, thereby the vicinity of one end portion of the first and second FPC portions 10 and 11. The parts are connected by attaching them externally with tape.
また、接続規制用連結部１２は２つの湾曲部Ｓ１，Ｓ２を有し、接続端子部１０ａ，１１ａ側の湾曲部Ｓ１から接続端子部１０ａ，１１ａ先端までの距離をＦとし、接続端子部１０ｂ，１１ｂ側の湾曲部Ｓ２から接続端子部１０ｂ，１１ｂ先端までの距離をＧとしたとき、距離Ｇ＞距離Ｆとなっている。 The connection restricting coupling portion 12 has two curved portions S1 and S2. The distance from the curved portion S1 on the connection terminal portions 10a and 11a side to the tip of the connection terminal portions 10a and 11a is F, and the connection terminal portion 10b. , 11b, the distance G from the curved portion S2 to the tips of the connecting terminal portions 10b, 11b is G> distance F.
尚、第１配線部（第１ＦＰＣ部１０）と第２配線部（第２ＦＰＣ部１１）と接続部（接続規制用連結部１２）を別体構造とすることで、ＦＰＣ製造時の基本となるシートサイズ（ワークサイズ）にＦＰＣの配線部を設定できので、ＦＰＣ部１０，１１等で示した配線部の個数を自由に増減できる。
（変形例）
このように接続部自体は汎用の粘着テープで代用して第１配線部（第１ＦＰＣ部１０）＋第２配線部（第２ＦＰＣ部１１）＋接続部（粘着テープ片１２ａ，１２ｂからなる接続規制用連結部１２）として１つのＦＰＣ３とすることもできる。この場合、粘着テープの貼り付け基準となる位置を示す目印などを第１配線部である第１ＦＰＣ部１０と第２配線部である第２ＦＰＣ部１１の表面および裏面に対応して設けておいて、この目印の部分に粘着テープ片１２ａ（１２ｂ）を貼り付けるようにすると良い。この目印としては、特定パターン、外形穴、外形溝、線などを用いることができる
例えば、図８（ａ）は目印の一例を示したもので、粘着テープの貼り付け基準となる位置を示すテープ幅のパターン目印Ｍを第１配線部である第１ＦＰＣ部１０と第２配線部である第２ＦＰＣ部１１の表面および裏面に対応して設けておいて、このパターン目印Ｍの部分に粘着テープ片１２ａ（１２ｂ）を貼り付けることにより、図８（ｂ）のように第１，第２ＦＰＣ部１０，１１を粘着テープ製の接続規制用連結部（接続部）１２としたものである。この構成によれば、パターン目印Ｍに一致するように粘着テープ片１２ａ（１２ｂ）を貼り付けることで、第１，第２ＦＰＣ部１０，１１の間隔や、粘着テープ片１２ａ（１２ｂ）の第１，第２ＦＰＣ部１０，１１の長手方向への接着位置を正確且つ容易に設定できるので、貼り付け作業が容易となる。
（発明の実施の形態の説明１）
以上説明したように、この発明の実施の形態のプリント基板の接続構造は、第１のプリント基板１の上に設けられた配線用コネクタ部１ａと、第２のプリント基板２の上に設けられた配線用コネクタ部２ａと前記第１配線用コネクタ部１ａと第２配線用コネクタ部２ａを接続するＦＰＣ３を備えている。しかも、前記配線用コネクタ部１ａ，２ａは、前記ＦＰＣ３が挿入される方向と直交する方向に配置された同一構造で同一ピン数からなる１組（一対）の配線用コネクタ（ＦＰＣ接続用コネクタ基板４，５とＦＰＣ接続用コネクタ基板６，７、又はＦＰＣ接続用コネクタ基板４Ａ，５ＡとＦＰＣ接続用コネクタ基板６Ａ，７Ａ）をそれぞれ有する。また、前記ＦＰＣ３は前記第１のプリント基板１上の一方の配線用コネクタ（ＦＰＣ接続用コネクタ基板４又は４Ａ）と前記第２のプリント基板２上の一方の配線用コネクタ（ＦＰＣ接続用コネクタ基板６又は６Ａ）を接続する第１配線部（第１ＦＰＣ部１０又は１０Ａ）と、前記第１のプリント基板１上の他方の配線用コネクタ（ＦＰＣ接続用コネクタ基板５又は５Ａ）と前記第２のプリント基板２上の他方の配線用コネクタ（ＦＰＣ接続用コネクタ基板７又は７Ａ）を接続する第２配線部（第２ＦＰＣ部１１又は１１Ａ）と、該第１の配線部（第１ＦＰＣ部１０又は１０Ａ）と第２の配線部（第２ＦＰＣ部１１又は１１Ａ）を一体とするように接続する接続部（接続規制用連結部１２）とを備えている。そして、前記ＦＰＣ３が正しい向きで前記配線用コネクタ（ＦＰＣ接続用コネクタ基板４，５とＦＰＣ接続用コネクタ基板６，７、又はＦＰＣ接続用コネクタ基板４Ａ，５ＡとＦＰＣ接続用コネクタ基板６Ａ，７Ａ）に接続されたときは、前記第１のプリント基板１と第２のプリント基板２のいずれか一方に配置された突起部（接続規制突部９）に対して前記接続部（接続規制用連結部１２）が干渉を回避し、該ＦＰＣ３が正しくない向きで前記配線用コネクタ（ＦＰＣ接続用コネクタ基板４，５とＦＰＣ接続用コネクタ基板６，７、又はＦＰＣ接続用コネクタ基板４Ａ，５ＡとＦＰＣ接続用コネクタ基板６Ａ，７Ａ）に接続されたときは前記突起部（接続規制突部９）に対して前記接続部（接続規制用連結部１２）が干渉するように、前記突起部（接続規制突部９）および前記接続部（接続規制用連結部１２）の外形形状が設定されている。
The first wiring part (first FPC part 10), the second wiring part (second FPC part 11), and the connection part (connection restricting connecting part 12) are formed as separate structures, which is the basis for FPC manufacturing. Since the FPC wiring section can be set to the sheet size (work size), the number of wiring sections indicated by the FPC sections 10 and 11 can be freely increased or decreased.
(Modification)
In this way, the connection part itself is replaced with a general-purpose adhesive tape, and the first wiring part (first FPC part 10) + second wiring part (second FPC part 11) + connection part (connection regulation comprising adhesive tape pieces 12a, 12b) One connecting part 12) may be one FPC3. In this case, marks or the like indicating the position to be a reference for attaching the adhesive tape are provided corresponding to the front and back surfaces of the first FPC portion 10 as the first wiring portion and the second FPC portion 11 as the second wiring portion. The adhesive tape piece 12a (12b) may be attached to the mark portion. As this mark, a specific pattern, an outer shape hole, an outer shape groove, a line, or the like can be used. For example, FIG. 8A shows an example of a mark, which indicates a position that is a reference for attaching an adhesive tape.

（発明の実施の形態の説明２）
また、この発明の実施の形態のプリント基板の接続構造において、前記ＦＰＣ（３，３Ａ）は、前記接続部（接続規制用連結部１２）を除いて前記第１の配線部（第１ＦＰＣ部１０又は１０Ａ）と第２の配線部（第２ＦＰＣ部１１又は１１Ａ）が分離している。
According to this configuration, even when a general-purpose connector is used, erroneous insertion of the FPC (3, 3A) can be prevented. By eliminating erroneous insertion in this manner, the manufacturing cost can be reduced because failures in the printed circuit board and the FPC are reduced.
(Description of Embodiment 2 of the Invention)
In the printed circuit board connection structure according to the embodiment of the present invention, the FPC (3, 3A) includes the first wiring portion (first FPC portion 10) except for the connection portion (connection restricting coupling portion 12). Or 10A) and the second wiring part (second FPC part 11 or 11A) are separated.
この構成によれば、第１の配線部（第１ＦＰＣ部１０又は１０Ａ）と第２の配線部（第２ＦＰＣ部１１又は１１Ａ）をＦＰＣ（３，３Ａ）に設けることで、ＦＰＣ（３，３Ａ）のプリント基板（第1，第2のプリント基板１，２）に接続される配線接続部分が少なくなるので、第１の配線部（第１ＦＰＣ部１０又は１０Ａ）と第２の配線部（第２ＦＰＣ部１１又は１１Ａ）をＦＰＣ（３，３Ａ）はこれらをまとめた一つの配線部にした場合に比べて自由に動くことができ、コネクタ（ＦＰＣ接続用コネクタ基板４，５又は６，７）の取り付けばらつきなどに対処し易くなる。しかも、単純に第１の配線部（第１ＦＰＣ部１０又は１０Ａ）と第２の配線部（第２ＦＰＣ部１１又は１１Ａ）の２つの配線部を接続部（接続規制用連結部１２）でつなぐ構成であるので、第１の配線部（第１ＦＰＣ部１０又は１０Ａ）と第２の配線部（第２ＦＰＣ部１１又は１１Ａ）の接続部（接続規制用連結部１２）から配線用コネクタ（ＦＰＣ接続用コネクタ基板４〜７）までの距離はある程度離れることになって、各配線部（第１ＦＰＣ部１０，１１又は１０Ａ，１１Ａ）は自由に動くことができる。
（発明の実施の形態の説明３）
また、この発明の実施の形態のプリント基板の接続構造において、前記突起部（接続規制突部９）は、前記１組のコネクタの間に対応する位置で且つ前記ＦＰＣ（３，３Ａ）の挿入方向側の位置に配置された電子部品とする。
According to this configuration, the FPC (3, 3A) is provided by providing the first wiring portion (first FPC portion 10 or 10A) and the second wiring portion (second FPC portion 11 or 11A) in the FPC (3, 3A). ) Of printed circuit boards (first and second printed circuit boards 1 and 2) are reduced, so that the first wiring section (first FPC section 10 or 10A) and the second wiring section (first The FPC (3, 3A) can be moved freely compared to the case where the FPC (3, 3A) is a single wiring unit, and the connector (connector board for FPC connection 4, 5 or 6, 7). This makes it easier to deal with mounting variations. In addition, the first wiring portion (first FPC portion 10 or 10A) and the second wiring portion (second FPC portion 11 or 11A) are simply connected by a connecting portion (connection restricting coupling portion 12). Therefore, the wiring connector (for FPC connection) from the connection portion (connection restricting connection portion 12) between the first wiring portion (first FPC portion 10 or 10A) and the second wiring portion (second FPC portion 11 or 11A). The distance to the connector boards 4 to 7) is somewhat deviated, and each wiring part (first FPC part 10, 11 or 10A, 11A) can move freely.
(Description 3 of the embodiment of the invention)
In the printed circuit board connection structure according to the embodiment of the present invention, the protrusion (connection restricting protrusion 9) is located at a position corresponding to between the pair of connectors and the FPC (3, 3A) is inserted. It is assumed that the electronic component is disposed at a position on the direction side.
この構成によれば、突起部を配設する位置が第１の配線部と第２の配線部の間であるので、ＦＰＣ全体が大きくなることがない。しかも、プリント基板に設ける突起部として電子部品（例えばある程度高さのあるチップ抵抗やチップコンデンサ）を接続規制突部９として用いることで、突起部（接続規制突部９）を個別に用意しなくても済むことになる。尚、組立時に突起部が目立つように特定色のモールド部材をプリント基板の所定箇所に穴を設けて取り付けることなども考えられる。
（発明の実施の形態の説明４）
