Description

本発明は、例えば、携帯電話、ＰＤＡ、パーソナルコンピュータ、電子ゲーム機等において使用される、光導波路などのフレキシブル配線基板を接続したコネクタから、当該フレキシブル配線基板が外力で容易に外れないようにするコネクタのロック機構に関するものである。   The present invention prevents a flexible wiring board from being easily detached by an external force from a connector connected to a flexible wiring board such as an optical waveguide, which is used in, for example, a mobile phone, a PDA, a personal computer, an electronic game machine, and the like. The present invention relates to a connector locking mechanism.

従来、光信号若しくは電気信号またはこれらを組合わせたもののフレキシブルなケーブルをコネクタに接続する際には、抜け止めとして例えば、図６に示すように、フレキシブル基板１６の側縁部に、係止用の突起１６ａを設けたものが知られている（特許文献１参照）。これは、コネクタ１５側の押圧部材１５ａに、押圧面側に向かって突出する抜け止め部１５ｂが設けられ、このコネクタ１５に装着されるフレキシブル基板１６の嵌合部の一部に、突出部１６ａが形成されていて、前記押圧部材１５ａを軸部中心に回転させて閉鎖すると、前記抜け止め部１５ｂが前記突出部１６ａをロックする、というものである。
特開２００３−２０８９４６号公報 Conventionally, when connecting a flexible cable of an optical signal or an electric signal or a combination of these to a connector, as a retainer, for example, as shown in FIG. The thing which provided the processus | protrusion 16a of this is known (refer patent document 1). This is because the pressing member 15a on the connector 15 side is provided with a retaining portion 15b that protrudes toward the pressing surface, and the protruding portion 16a is formed on a part of the fitting portion of the flexible substrate 16 that is attached to the connector 15. When the pressing member 15a is rotated around the shaft portion and closed, the retaining portion 15b locks the protruding portion 16a.

また、前記ケーブルにおいて、光信号を有する場合における光導波路とコネクタ側の発光素子（受光素子）との結合方法は、光信号をレンズで集光させるか、位置精度を高めて直接素子と結合させるものである。   In addition, in the cable, when the optical signal has an optical signal, the optical waveguide and the light emitting element (light receiving element) on the connector side can be combined with the optical signal by condensing the optical signal with a lens or directly with the element. Is.

しかし、従来のコネクタのロック機構においては、ケーブルの幅を越えて外側に飛び出しており、ケーブルの歩留まりが悪くなる。また、逆に、ケーブルに切り欠きや、孔部を設けて抜け止めとすると、ケーブルが引っ張られたときにケーブルの破損などが大きくなり、電気信号路や光導波路に対するダメージが避けられなくなる。   However, in the conventional connector locking mechanism, the cable protrudes outward beyond the width of the cable, resulting in poor cable yield. On the other hand, if the cable is notched or provided with a hole to prevent the cable from being damaged, the cable is greatly damaged when the cable is pulled, and damage to the electric signal path and the optical waveguide cannot be avoided.

一方、光導波路における結合方法においても、ケーブルをコネクタに接合させて、単に、抜け止めを防止する手段を設けただけでは、取付けの寸法誤差により接合部の光学結合効率が向上しない。これを向上させようとすると、組立精度を高めねばならず、微調節が必要となって手間の掛かる作業となる。よって、コネクタ組立の作業工数が増大してコストが嵩むことになる。本発明に係るコネクタのロック機構は、このような課題を解決するために提案されたものである。   On the other hand, also in the coupling method in the optical waveguide, the optical coupling efficiency of the joint portion is not improved due to the dimensional error of the attachment simply by joining the cable to the connector and simply providing a means for preventing the cable from coming off. In order to improve this, assembly accuracy must be increased, and fine adjustment is required, which is a laborious operation. Therefore, the man-hours for connector assembly increase and the cost increases. The connector locking mechanism according to the present invention has been proposed in order to solve such problems.

本発明に係るコネクタのロック機構の上記課題を解決して目的を達成するための要旨は、信号伝達用フレキシブル配線基板を蓋部材の閉蓋作用によって接続部に固定して光信号又は電気信号を伝達させるコネクタのロック機構において、前記接続部に収納される前記フレキシブル配線基板の片側面に、所望の板厚を有する補強板が固着されていて、前記蓋部材で前記補強板を押圧して前記接続部に固定するとともに、前記接続部を閉蓋する蓋部材に、前記接続部に装着されたフレキシブル配線基板の補強板の抜去側の側端面に係止して、当該フレキシブル配線基板の抜去を阻止する抜去防止部材が設けられていて、前記補強板は、蓋部材の閉蓋作用を緩和させる緩衝性部材で形成されており、
前記フレキシブル配線基板は、光信号用フレキシブル配線基板、電気信号用フレキシブル配線基板または光・電気信号用フレキシブル配線基板のうちのいずれか一つであって、前記蓋部材には、接続部に閉蓋されてフレキシブル配線基板をロックする際に、前記フレキシブル配線基板を挿入方向に向けて付勢する付勢手段が設けられていることである。 The gist of the present invention for solving the above-mentioned problems of the connector locking mechanism according to the present invention is to fix the signal transmission flexible wiring board to the connecting portion by the lid-closing action of the lid member, and to transmit an optical signal or an electrical signal. In the connector locking mechanism to be transmitted, a reinforcing plate having a desired plate thickness is fixed to one side surface of the flexible wiring board accommodated in the connecting portion, and the reinforcing plate is pressed against the reinforcing plate by the lid member. While fixing to the connection part, the lid member that closes the connection part is engaged with the side end surface on the extraction side of the reinforcing plate of the flexible wiring board attached to the connection part, and the flexible wiring board is removed. An extraction preventing member for blocking is provided, and the reinforcing plate is formed of a cushioning member that relaxes the closing action of the lid member,
The flexible wiring board is any one of an optical signal flexible wiring board, an electrical signal flexible wiring board, or an optical / electrical signal flexible wiring board, and the lid member is closed at a connection portion. When the flexible wiring board is locked, an urging means for urging the flexible wiring board in the insertion direction is provided.

前記付勢手段は、フレキシブル配線基板の先端面が接続部の挿入方向側の壁面に常に当接する状態を維持するように付勢していることである。
更に、前記フレキシブル配線基板が光信号用フレキシブル配線基板又は光・電気信号用フレキシブル配線基板である場合に、フレキシブル配線基板の先端面と受発光素子との間には平行レンズが設けられているが好ましい。
前記補強板は、その内部にフレキシブル配線基板の先端部を仮固定するための磁性粉が含有されて形成されていることを含むものである。 The biasing means biases the front end surface of the flexible wiring board so as to maintain a state in which the front end surface is always in contact with the wall surface on the insertion direction side of the connection portion.
Furthermore, when the flexible wiring board is an optical signal flexible wiring board or an optical / electrical signal flexible wiring board, a parallel lens is provided between the front end surface of the flexible wiring board and the light emitting and receiving element. preferable.
The reinforcing plate includes that the inside of the reinforcing plate contains magnetic powder for temporarily fixing the tip of the flexible wiring board .

本発明のコネクタのロック機構によれば、信号伝達用フレキシブル配線基板を蓋部材の閉蓋作用によって接続部に固定して光信号又は電気信号を伝達させるコネクタのロック機構において、前記接続部に収納される前記フレキシブル配線基板の片側面に、所望の板厚を有する補強板が固着されていて、コネクタの接続部に固定されるので蓋部材により確実に固定される。また、前記補強板の抜去側の側端面に係止する抜去防止部材が前記接続部を閉蓋する蓋部材に設けられているので、フレキシブル配線基板が引っ張られても容易に抜け出すことがない。よって、確実な接続状態が維持されて光信号又は電気信号の接続安定性が高く、信頼性が高く維持される。   According to the connector locking mechanism of the present invention, the signal transmission flexible wiring board is fixed to the connection portion by the lid closing action of the lid member, and is accommodated in the connection portion in the connector lock mechanism for transmitting an optical signal or an electric signal. A reinforcing plate having a desired plate thickness is fixed to one side surface of the flexible printed circuit board, and is fixed to the connection portion of the connector, so that it is securely fixed by the lid member. In addition, since the removal preventing member that is locked to the side end surface on the removal side of the reinforcing plate is provided on the lid member that closes the connection portion, it does not easily come out even if the flexible wiring board is pulled. Therefore, a reliable connection state is maintained, the connection stability of the optical signal or the electric signal is high, and the reliability is maintained high.

前記フレキシブル配線基板は、光信号用フレキシブル配線基板、電気信号用フレキシブル配線基板または光・電気信号用フレキシブル配線基板のうちのいずれか一つであり、各種のフレキシブル配線基板に適用できるロック構造である。
また、前記蓋部材には、接続部に閉蓋されてフレキシブル配線基板をロックする際に、フレキシブル配線基板を挿入方向に付勢する付勢手段があるので、接続が確実に行われて安定する。更に、接続部の挿入方向側の壁面に前記フレキシブル配線基板の先端面が常に当接する状態を維持するように前記付勢手段が付勢するので、安定した接続状態が維持され、信頼性が向上するものである。 The flexible wiring board is one of a flexible wiring board for optical signals, a flexible wiring board for electrical signals, or a flexible wiring board for optical / electrical signals, and has a lock structure applicable to various flexible wiring boards. .
The lid member has a biasing means for biasing the flexible wiring board in the insertion direction when the flexible wiring board is locked by being closed by the connecting portion, so that the connection is reliably performed and stabilized. . Further, since the urging means urges the state where the front end surface of the flexible wiring board is always in contact with the wall surface on the insertion direction side of the connection portion, a stable connection state is maintained and reliability is improved. To do.

フレキシブル配線基板が光信号用フレキシブル配線基板又は光・電気信号用フレキシブル配線基板である場合に、フレキシブル配線基板の先端面と受発光素子との間には平行レンズが設けられているので、光接合効率を減少させることなく、取付位置寸法を比較的ラフに設計できて、組立が容易となって組立工数も低減できてコスト低減となる。   When the flexible wiring board is a flexible wiring board for optical signals or a flexible wiring board for optical / electrical signals, a parallel lens is provided between the front end surface of the flexible wiring board and the light emitting / receiving element. Without reducing efficiency, the mounting position dimensions can be designed relatively rough, making assembly easier, reducing the number of assembly steps, and reducing costs.

更に、前記補強板は、その内部に磁性粉が含有されて形成されているようにすることで、コネクタにおける接続部に、フレキシブル配線基板の先端部を載置してそのまま仮固定できるので、作業が容易となって作業能率が向上する。   Furthermore, since the reinforcing plate is formed with magnetic powder contained therein, the tip of the flexible wiring board can be placed on the connecting portion of the connector and temporarily fixed as it is. Becomes easier and the work efficiency is improved.

本発明に係るコネクタ１のロック機構Ａは、図１−Ａ、図１−Ｂに示すように、信号伝達用フレキシブル配線基板２を蓋部材３の閉蓋作用によって接続部４に固定して光信号又は電気信号を伝達させるコネクタのロック機構において、前記接続部４に収納される前記フレキシブル配線基板２の先端部２ａにおける片側面に、所望の板厚を有する補強板５が固着されていて、前記接続部４に装着された前記補強板５の抜去側の側端面５ａに係止して当該フレキシブル配線基板４の抜去を阻止する抜去防止部材６が、前記接続部４を閉蓋する蓋部材３に設けられていることである。   As shown in FIGS. 1A and 1B, the lock mechanism A of the connector 1 according to the present invention fixes the signal transmitting flexible wiring board 2 to the connection portion 4 by the lid closing action of the lid member 3. In the connector locking mechanism for transmitting a signal or an electric signal, a reinforcing plate 5 having a desired plate thickness is fixed to one side surface of the distal end portion 2a of the flexible wiring board 2 housed in the connection portion 4. A removal preventing member 6 that locks on the side end surface 5a on the removal side of the reinforcing plate 5 attached to the connection portion 4 and prevents the flexible wiring board 4 from being removed is a lid member that closes the connection portion 4. 3 is provided.

前記コネクタ１は、図２に示すフレキシブル配線基板用の接続コネクタであり、合成樹脂製の本体１ａに、金属製のシェル１ｂが全体に被せられ、そのシェル１ｂに表面実装用の脚部１ｃが設けられ、金属製の蓋部材３が前記本体１ａから突設された回転軸１ｄに回転自在に支持されている。   The connector 1 is a connector for a flexible wiring board shown in FIG. 2, and a metal shell 1b is entirely covered on a synthetic resin main body 1a, and a surface mounting leg 1c is provided on the shell 1b. A metal lid member 3 is rotatably supported on a rotating shaft 1d protruding from the main body 1a.

前記本体１ａの下面に突設されているボス１ｅは、プリント基板に実装される際の位置決めとなるものである。また、前記本体１には、接続部４に電気信号用のコンタクト７が圧入等の手段で固着されている。このコネクタ１の全体の大きさは、縦が約１２ｍｍ、横が約５ｍｍ、高さが約２ｍｍ程度の小さなものである。   The boss 1e protruding from the lower surface of the main body 1a is used for positioning when mounted on a printed circuit board. In the main body 1, an electrical signal contact 7 is fixed to the connection portion 4 by means such as press fitting. The overall size of the connector 1 is as small as about 12 mm in length, about 5 mm in width, and about 2 mm in height.

前記フレキシブル配線基板２は、光信号用フレキシブル配線基板、電気信号用フレキシブル配線基板または光・電気信号用フレキシブル配線基板のうちのいずれか一つである。この実施例では、光・電気信号用の光電複合フレキシブル配線基板の例を示している。   The flexible wiring board 2 is one of a flexible wiring board for optical signals, a flexible wiring board for electrical signals, or a flexible wiring board for optical / electrical signals. In this embodiment, an example of a photoelectric composite flexible wiring board for optical / electrical signals is shown.

前記蓋部材３には、接続部４に閉蓋されてフレキシブル配線基板２をロックする際に、接続部４の挿入方向側の壁面８ａに前記フレキシブル配線基板２の先端面２ｂが常に当接する状態を維持するように、当該フレキシブル配線基板２を挿入方向に向けて付勢する付勢手段１０が、図３に示すように、設けられている。   When the lid 3 is closed by the connecting portion 4 to lock the flexible wiring board 2, the tip surface 2 b of the flexible wiring board 2 is always in contact with the wall surface 8 a on the insertion direction side of the connecting portion 4. As shown in FIG. 3, a biasing means 10 that biases the flexible wiring board 2 toward the insertion direction is provided.

この実施例では、例えば、蓋部材３の左右の側壁３ａ，３ｂの軸部分において、回転中心１ｇからの距離が途中から短くなるようなスリット３ｃを設ける。そして、回転軸１ｄ側に、前記スリット３ｃに係合する突起１ｆを形成する。   In this embodiment, for example, slits 3c are provided in the shaft portions of the left and right side walls 3a and 3b of the lid member 3 so that the distance from the rotation center 1g is shortened from the middle. And the protrusion 1f engaged with the said slit 3c is formed in the rotating shaft 1d side.

前記スリット３ｃは、蓋部材３が略直角に起立された全開状態から、水平に閉蓋される手前位置までの間は、半径ｒでスリットが形成され、それから閉蓋されるまでの間は、半径ｒの円弧ではなく半径ｒよりも短い距離の点から半径に対して直交する方向に直線状にした直線部分３ｄにして形成されている。   The slit 3c has a radius r between the fully open state in which the lid member 3 is erected at a substantially right angle and the front position where the lid member 3 is horizontally closed, and until the lid is closed. It is not a circular arc of radius r, but is formed as a linear portion 3d that is linear from a point at a distance shorter than radius r in a direction orthogonal to the radius.

これにより、前記突起１ｆが、回転してきたスリット３ｃの直線部分３ｄにかかると、図３（Ｂ）に示すように、回転軸１ｄの回転中心１ｇからの距離が半径ｒより短いので、相対的に蓋部材３が挿入方向に付勢される。   As a result, when the protrusion 1f is applied to the linear portion 3d of the slit 3c that has rotated, the distance from the rotation center 1g of the rotation shaft 1d is shorter than the radius r as shown in FIG. The lid member 3 is biased in the insertion direction.

上記実施例はあくまでも、一例であり、このほか、図５（Ａ）〜（Ｃ）に示すように、、円弧状突起１１により、側壁３ａ，３ｂに設けられて係合する窓３ｅが付勢する方向に寄せられるようにしたり、斜めスライド部１２に蓋部材３の一部（蓋部材３が逆向きに取り付けられている例である）が係合して付勢方向に寄せられるようにしたり、その他、蓋部材３全体が合成樹脂製であって付勢力が作用するように変形可能にしたり、種々の公知の付勢手段を採用できるものである。   The above embodiment is merely an example. In addition, as shown in FIGS. 5A to 5C, the arc-shaped protrusion 11 urges the windows 3e provided on the side walls 3a and 3b to be engaged. Or a part of the lid member 3 (which is an example in which the lid member 3 is attached in the opposite direction) is engaged with the oblique slide portion 12 so as to be brought toward the biasing direction. In addition, the entire lid member 3 is made of synthetic resin and can be deformed so that an urging force is applied, or various known urging means can be employed.

前記フレキシブル配線基板２が光信号用フレキシブル配線基板又は光電複合フレキシブル配線基板である場合に、図４（Ａ），（Ｂ）に示すように、フレキシブル配線基板２の端面２ｂと受発光素子９との間には平行レンズ８が設けられている。尚、符号９は、光信号用の受発光素子を示している。よって、光電複合フレキシブル配線基板２の端面２ｂと、受発光素子９との理想的な距離を、厳密に設定する必要がなく、ラフに設定することができるので組立工数の削減となる。   When the flexible wiring board 2 is an optical signal flexible wiring board or a photoelectric composite flexible wiring board, as shown in FIGS. 4A and 4B, the end face 2b of the flexible wiring board 2 and the light receiving and emitting elements 9 A parallel lens 8 is provided between them. Reference numeral 9 denotes an optical signal receiving and emitting element. Therefore, the ideal distance between the end face 2b of the photoelectric composite flexible wiring board 2 and the light emitting / receiving element 9 does not need to be set strictly, and can be set roughly, thereby reducing the number of assembling steps.

前記補強板５は、図２に示すように、平板状の板部材であり、例えば、合成樹脂製である。尚、蓋部材３で押圧されるので、衝撃を避けるために硬質材ではなく、クッションのように緩衝性のある部材が好ましい。また、接合部４に仮置きした際に、簡単に落下しないように、この接合部４において弱く付着していることが好ましい。そこで、この補強板５の内部に、磁性粉が含有されて形成されるようにする。これにより、コネクタ１の接合部４にフレキシブル配線基板２の先端部２ａを載置したときに、金属製のコンタクト７に磁着することになって、仮置き状態が維持されて、当該フレキシブル配線基板２の先端部２ａが簡単に落下することがない。こうして、蓋部材３で先端部２ａを閉蓋するまで、作業が安定する。   As shown in FIG. 2, the reinforcing plate 5 is a flat plate member, and is made of, for example, a synthetic resin. In addition, since it presses with the cover member 3, in order to avoid an impact, not a hard material but a member with a buffer property like a cushion is preferable. Further, when temporarily placed on the joint 4, it is preferable that the joint 4 is weakly attached so that it does not fall easily. Therefore, the reinforcing plate 5 is formed so as to contain magnetic powder. Thereby, when the front-end | tip part 2a of the flexible wiring board 2 is mounted in the junction part 4 of the connector 1, it will magnetically adhere to the metal contacts 7, and a temporary placement state is maintained, The said flexible wiring The tip 2a of the substrate 2 is not easily dropped. In this way, the operation is stabilized until the tip 2a is closed with the lid member 3.

前記蓋部材３の抜去阻止部材６は、閉蓋状態で、補強板５を押さえ、その端部で直交して屈曲した阻止板６ａが設けられていて、抜去方向への抜け防止作用をする。   The removal preventing member 6 of the lid member 3 is provided with a blocking plate 6a that holds the reinforcing plate 5 in a closed state and is bent orthogonally at the end thereof, and prevents the removal in the removal direction.

以上のようにして形成されるコネクタ１のロック機構Ａにより、図１−Ａ（Ｂ）、図１−Ｂ（Ｂ）に示すように、コネクタ１の蓋部材３を全開させた状態にして、コネクタ１の接続部４に光電複合フレキシブル配線基板２の先端部２ａを載置する。   With the locking mechanism A of the connector 1 formed as described above, as shown in FIGS. 1A and 1B, the lid member 3 of the connector 1 is fully opened, The tip portion 2 a of the photoelectric composite flexible wiring board 2 is placed on the connection portion 4 of the connector 1.

前記先端部２ａは、コンタクト７に電気配線を接続させ、端面２ｂを挿入方向の壁面に当接させ突き当てにする。補強板５に、磁性粉が適宜量で含有されていれば、コンタクト７に吸着して、光電複合フレキシブル配線基板２が脱落しないように載置される。   The distal end portion 2a connects an electrical wiring to the contact 7 and abuts the end surface 2b against the wall surface in the insertion direction. If the reinforcing plate 5 contains magnetic powder in an appropriate amount, the reinforcing plate 5 is placed so as to be attracted to the contact 7 and the photoelectric composite flexible wiring board 2 does not fall off.

そして、蓋部材３を水平に倒して閉蓋させる。すると、抜去防止部材６の阻止板６ａにより、図４（Ａ）に示すように、補強板５が抜去方向に移動するのを阻止する。また、図３（Ｂ）に示すように、付勢手段１０により、フレキシブル配線基板２の端面２ａが壁面８ａに当接して維持され、光信号の光学結合効率の減少が抑えられる。   Then, the lid member 3 is tilted horizontally to close the lid. Then, the blocking plate 6a of the removal preventing member 6 prevents the reinforcing plate 5 from moving in the removal direction as shown in FIG. Further, as shown in FIG. 3B, the end face 2a of the flexible wiring board 2 is maintained in contact with the wall surface 8a by the biasing means 10, and the decrease in optical coupling efficiency of the optical signal is suppressed.

更に、前記付勢する付勢手段１０があることで、平行レンズ８を使用することができて受発光素子９の位置決めが容易となり、それによってコネクタ１の組立工数の削減となるものである。   Further, the presence of the urging means 10 for urging makes it possible to use the parallel lens 8 and facilitate the positioning of the light emitting / receiving element 9, thereby reducing the number of assembly steps of the connector 1.
