【発明の属する技術分野】
本発明はフレキシブル回路板（ＦＰＣ）を受容し、これと電気的接続されるフレキシブル回路板用コネクタに関する。
【０００２】
【従来の技術】
従来のこの種のフレキシブル回路板用コネクタの一例が特開昭６１−１３１３８２号に開示される。図５にこのフレキシブル回路板用コネクタ１００を示す。図５（ａ）に示すようにフレキシブル回路板用コネクタ１００はフォ−ク型のコンタクト１５０を収容する絶縁ハウジング１３０及び別体のプラグ部材１１０を有する。図５（ｂ）及び（ｃ）に断面図にして示すように、フレキシブル回路板用コネクタ１００は、プラグ部材１１０を（ｂ）に示す仮係止位置に置いてフレキシブル回路板Ｆを受容し、次にプラグ部材１１０を（ｃ）に示す本係止位置まで高さ方向に摺動させることによりフレキシブル回路板Ｆをプラグ部材１１０とコンタクト１５０との間に弾性的に挟持し、フレキシブル回路板Ｆとコンタクト１５０との電気的接続を実現する。
【０００３】
【発明の解決すべき課題】
しかしながら、上述の公報に開示されるフレキシブル回路板用コネクタ１００はフレキシブル回路板の接続を手作業で行うのには適しているが、プラグ部材１１０を直線的摺動により係止位置から本係止位置に移動するよう構成されているため、プラグ部材１１０を仮係止位置で安定に維持できないこと、及びプラグ部材１１０が仮係止位置にしてフレキシブル回路板Ｆを絶縁ハウジング１３０に受容させるのが難しいことからロボット等により行う自動組立接続には適していない。本発明の目的は自動組立接続に適した構成を具えるフレキシブル回路板用コネクタを提供することにある。
【０００４】
【課題を解決するための手段】
本発明に係るフレキシブル回路板用コネクタは、複数のコンタクトを収容する絶縁ハウジングの一面に略矩形の開口を形成し、該開口の一縁側にフレキシブル回路板を位置合わせして配置する回路板配置部を設け、対向縁側に前記絶縁ハウジングに対して回動可能なプラグ部材を仮係止して配置し、前記プラグ部材を仮係止位置から本係止位置へ向けて回動させることにより、前記プラグ部材の回動半径方向に略直角な面と前記複数のコンタクトとの間に前記フレキシブル回路板を弾性的に挟持し、前記フレキシブル回路板を前記複数のコンタクトと電気的に接続させるフレキシブル回路板用コネクタであって、前記コンタクトは、前記開口の一縁側に位置する接触アーム、及び前記開口の前記対向縁側に位置すると共に先端に水平に突出する舌状部が設けられて略Ｌ字形状をなすプラグ支持アームからなる接触部を有し、前記プラグ部材の回動過程において、前記プラグ支持アームの前記舌状部は前記プラグ部材の突起と略常時当接しているフレキシブル回路板用コネクタにおいて、前記プラグ部材の本係止位置において、略直角に曲げられて前記絶縁ハウジングの前記開口内に押し入れられた前記フレキシブル回路板及び前記プラグ部材を、前記接触アームと前記プラグ支持アームとの間に弾性的に挟持し、前記プラグ部材の前記回動半径に略直角な面は、前記プラグ部材の前記仮係止位置において前記フレキシブル回路板用コネクタの略上端に位置する吸着面を構成することを特徴とする。
【０００５】
好ましくは、前記プラグ部材は前記絶縁ハウジングに対して前記仮係止位置から約９０度の回動により前記本係止位置に至り、該本係止位置においては前記プラグ部材は前記一面側で前記絶縁ハウジングと略同一面となるよう配置される。
【０００６】
更に前記回路板配置部は略平坦な回路板収容部と、前記フレキシブル回路板と係合する係合突起とを含むよう構成されても良い。
【０００７】
更に前記プラグ部材は前記仮係止位置から前記本係止位置までの回動の間、略常時前記複数のコンタクトと接触する突起を有するのが好ましい。
【０００８】
更に好ましくは前記絶縁ハウジングは前記開口を頂側に向けて回路基板上に実装されるのが良い。このとき前記プラグ部材は前記本係止位置で前記フレキシブル回路板を前記回路基板に平行に延出させるガイド片を有するのが好ましい。更に前記フレキシブル回路板を前記コンタクトとの間に狭持する前記面は吸着装置により吸着され前記フレキシブル回路板用コネクタを所定の実装位置に配置するための吸着面として使用できるのが好ましい。
【０００９】
【発明の実施の形態】
以下に図面を参照して本発明の好適実施形態となるフレキシブル回路板用コネクタについて詳細に説明する。
【００１０】
図１は組立前のフレキシブル回路板用コネクタを示す斜視図であり、プラグ部材を仮係止位置にして示す図である。図２乃至図４はプラグ部材が仮係止位置から本係止位置に至るまでの過程を示す断面図である。
【００１１】
フレキシブル回路板用コネクタ１０は複数のコンタクト５０を収容する絶縁ハウジング３０、及びプラグ部材７０を有する。複数のコンタクト５０は列を成して配置され、絶縁ハウジング３０は複数のコンタクト５０の配置方向に細長に形成される。フレキシブル回路板用コネクタ１０は回路基板（図示せず）上に実装されるが絶縁ハウジング３０の長さ方向の両端側壁面３０ａ、３０ｂには回路基板への固定を補強するための補強部材８０が取り付けられる。更にプラグ部材７０は両端側壁面３０ａ、３０ｂに軸支され、絶縁ハウジングに対して回動可能に保持される。図１乃至図４には回動軸をＰとして示す。図１によれば回動軸Ｐはプラグ部材７０の本体７１から側方に延長された略Ｌ字形状のアーム７２を通る位置にある。即ちアーム７２にはプラグ部材７０を絶縁ハウジング３０に対して回動可能に取り付けるための軸支手段が設けられる。更に、側壁面３０ａ、３０ｂはアーム７２と係合してプラグ部材７０を仮係止位置に維持するための姿勢維持用突起３２が設けられる。後述の如くアーム７２を収容する凹部３３、及び該凹部３３に沿った位置に形成される爪３４を有する。
【００１２】
図２乃至図４によればコンタクト５０は変形フォ−ク形状の接触部５１、絶縁ハウジング３０へ固定されるための圧入部５２、及び回路基板への接続のための半田付タイン部５３を有する。接触部５１は圧入部５２に比較的近い位置に配置されるプラグ支持アーム５５、及び圧入部５２から離れた位置まで延びる接触アーム５６を有する。プラグ支持アーム５５の端５５ａは接触アーム５６の端５６ａよりも高さ方向に高い位置に置かれ、端５５ａの近傍には舌状部５５ｂが水平に突出するよう設けられ略Ｌ字形状とされる。また接触アーム５６の端５６ａの近傍には接触用突起５６ｂが設けられる。接触部５１の作用については後述する。
【００１３】
図１乃至図４より理解されるように絶縁ハウジング３０には頂側に向いて開く略矩形の開口３０ｃが形成される。上述した複数のコンタクト５０の接触部５１はこの開口３０ｃ内に配置され、後述の如くプラグ部材７０との協働作用により開口３０ｃ内に受容されるフレキシブル回路板Ｆと電気的に接続される。図２乃至図４から理解されるようにプラグ部材７０の回動軸Ｐは開口３０ｃのエッジ（縁）３６に寄って位置する。図１乃至図２に示すようにプラグ部材７０が仮係止位置にあるときは、プラグ部材７０はこの絶縁ハウジング３０のエッジ３６側に位置する。また開口３０ｃのエッジ３６と対向する逆エッジ（逆縁）３７側には略平坦な回路板収容部３９ａとその両側に位置してフレキシブル回路板Ｆに形成された凹部９９と係合する位置合わせ用の係合突起３９ｂとから成る回路板配置部が構成される。
【００１４】
以下にフレキシブル回路板用コネクタとフレキシブル回路板Ｆとの自動組立接続の工程について順を追って説明する。
【００１５】
組立接続の第１工程ではプラグ部材７０を仮係止位置において、フレキシブル回路板Ｆを絶縁ハウジング３０の頂面３０ｄに配置する。このときフレキシブル回路板Ｆの凹部９９と絶縁ハウジング３０の一対の突起３９ｂとが係合するのでフレキシブル回路板は所定位置に正確に配置される。
【００１６】
図２にはフレキシブル回路板Ｆを所定位置に配置して示すが、組立接続の第２工程ではプラグ部材７０が図２に示す仮係止位置から図４に示す本係止位置に向けて図３中の矢印Ｒ方向に回動される。図２に示されるようにプラグ部材７０は第１面７０ａ、該第１面７０ａと略直交する第２面７０ｂ、該第２面７０ｂと対向位置に設けられる突起７０ｃ、該突起７０ｃに沿って位置する第３面７０ｄ及び第１面７０ａと対向位置にある第４面７０ｅを有する。図２に示すように仮係止位置においてはプラグ部材７０は直立して置かれ第１面７０ａが略垂直方向に、第２面７０ｂが略水平方向に向くように置かれる。第１面７０ａは図２に示す如くフレキシブル回路板Ｆの端位置を決定するストッパ面として機能し得る。更に水平方向に延びる第２面７０ｂは、フレキシブル回路板用コネクタ１０を回路基板の所定位置に自動配置するよう吸着装置に吸着されるための吸着面を構成する。また第３面７０ｄはコンタクト５０の舌状部５５ｂと略当接する。
【００１７】
図３にはプラグ装置７０の回動中途の状態が示される。回動の過程で第１面７０ａ、及び第１面７０ａと第２面７０ｂとの境界に位置する曲面７０ｆがフレキシブル回路板Ｆを開口３０ｃ内に押し入れる。図示されるように回動中途の状態でもプラグ部材７０の突起７０ｃに沿う第３面７０ｄはコンタクト５０の舌状部５５ｂに当接する。
【００１８】
図４にはプラグ部材７０を回動が完了した本係止位置に置いて示す。仮係止位置から本係止位置に到る過程で、プラグ部材７０は略９０°回動され、プラグ部材７０のアーム７２が凹部３３内に受容される。プラグ部材７０が本係止位置に達すると爪３４がプラグ部材７０に形成された、図示しない係合肩と係合し、これによりプラグ部材７０が本係止位置に維持される。プラグ部材７０が本係止位置にあるとき、フレキシブル回路板Ｆはコンタクト５０の接触アーム５６とプラグ部材７０の第２面７０ｂとの間に弾性的に挟持されて、接触用突起５６ｂを介して電気的接続される。接続されたフレキシブル回路板Ｆはプラグ部材７０のガイド片７８によって案内され側方（水平方向）に延出される。コンタクト５０のプラグ支持アーム５５は接触用突起５６ｂと対向する位置でプラグ部材７０の突起７０ｃと弾性的に当接し、プラグ部材７０を支持する。プラグ部材７０の軸支手段は若干の遊びを有するので、プラグ部材７０とフレキシブル回路板Ｆとはコンタクト５０の接触アーム５６とプラグ支持アーム５５との間に弾性的に挟持され、これによりフレキシブル回路板Ｆとコンタクト５０との安定した電気的接続が提供される。なお、プラグ部材７０が仮係止位置から本係止位置まで回動する過程で、プラグ部材７０の突起７０ｃに沿う第３面７０ｄが舌状部５５ｂと略常時当接する位置にある。これによりプラグ部材７０の突起７０ｃはコンタクト５０の舌状部５５ｂの下側位置にスムーズにまわり込むことができ、プラグ支持アーム５５に不要な力が加わる慮れがない。
【００１９】
また図４から理解されるようにプラグ部材７０が本係止位置にあるときには第４面７０ｅは絶縁ハウジング３０の頂面３０ｄと略一面を成す。従って図２乃至図４に示すプラグ部材７０の回動過程において、プラグ部材７０を回動させる（図３中に回動方向を矢印Ｒで示す。）ために、図３中に示すＴｒの如き回動力を加えても良いし、同図に示すＦｓの如く、直線的に摺動する部材による押圧力を加えても良い。後者の場合、摺動部材の一部を頂面３０ｄの近接位置で摺動させることによりプラグ部材７０を本係止位置まで完全に回動させることができる。
【００２０】
以上の如く本発明の好適実施形態となるフレキシブル回路板用コネクタについて説明したが、これは本発明を制限するものではなく、当業者により様々な変形変更が可能である。
【００２１】
【発明の効果】
本発明のフレキシブル回路板用コネクタによれば、複数のコンタクトを収容する絶縁ハウジングの一面に略矩形の開口を形成し、該開口の一縁側にフレキシブル回路板を位置合わせして配置する回路板配置部を設け、対向縁側に絶縁ハウジングに対して回動可能なプラグ部材を係止して配置し、プラグ部材を本係止位置へ向けて回動させることにより回路板配置部に配置されたフレキシブル回路板を絶縁ハウジングの開口内に押し入れるよう構成されるので、フレキシブル回路板とコネクタとの接続組立を自動組立装置により容易に行うことができる。特にフレキシブル回路板を所定位置に配置して接続できるので接続の信頼性が高く、また、接続組立までの間プラグ部材を安定的に絶縁ハウジング上に維持できる。加えて、プラグ部材の回動によりフレキシブル回路板との接続時に効果的なワイピング作用を行うことができるので確実な電気的接続が実現される。

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a flexible circuit board connector according to a preferred embodiment of the present invention will be described in detail with reference to the drawings.
[0010]
FIG. 1 is a perspective view showing a flexible circuit board connector before assembly, and shows a plug member in a temporary locking position. 2 to 4 are cross-sectional views showing the process from the temporary locking position to the final locking position of the plug member.
[0011]

The plurality of contacts 50 are arranged in a row, and the insulating housing 30 is formed in an elongated shape in the arrangement direction of the plurality of contacts 50. The flexible circuit board connector 10 is mounted on a circuit board (not shown), but reinforcing members 80 for reinforcing the fixing to the circuit board are provided on both side wall surfaces 30a, 30b in the length direction of the insulating housing 30. It is attached. Further, the plug member 70 is pivotally supported on the side wall surfaces 30a and 30b at both ends, and is held so as to be rotatable with respect to the insulating housing. 1 to 4, the rotation axis is indicated as P. According to FIG. 1, the pivot axis P is at a position passing through a substantially L-shaped arm 72 extending laterally from the main body 71 of the plug member 70. That is, the arm 72 is provided with a shaft support means for rotatably mounting the plug member 70 with respect to the insulating housing 30. Further, the side wall surfaces 30a and 30b are provided with posture maintaining protrusions 32 for engaging the arm 72 and maintaining the plug member 70 in the temporary locking position. As will be described later, it has a recess 33 for accommodating the arm 72 and a claw 34 formed at a position along the recess 33.
[0012]
2 to 4, the contact 50 has a deformed fork-shaped contact portion 51, a press-fit portion 52 for fixing to the insulating housing 30, and a soldered tine portion 53 for connection to a circuit board. . The contact portion 51 includes a plug support arm 55 disposed at a position relatively close to the press-fit portion 52 and a contact arm 56 extending to a position away from the press-fit portion 52. An end 55a of the plug support arm 55 is placed at a position higher in the height direction than the end 56a of the contact arm 56, and a tongue-like portion 55b is provided in the vicinity of the end 55a so as to protrude horizontally, and has an approximately L shape. The A contact projection 56 b is provided in the vicinity of the end 56 a of the contact arm 56. The operation of the contact portion 51 will be described later.
[0013]
As understood from FIGS. 1 to 4, the insulating housing 30 is formed with a substantially rectangular opening 30 c that opens toward the top. The contact portions 51 of the plurality of contacts 50 described above are disposed in the opening 30c, and are electrically connected to the flexible circuit board F received in the opening 30c by the cooperative action with the plug member 70 as described later. As understood from FIGS. 2 to 4, the rotation axis P of the plug member 70 is located closer to the edge 36 of the opening 30 c. As shown in FIGS. 1 and 2, when the plug member 70 is in the temporary locking position, the plug member 70 is positioned on the edge 36 side of the insulating housing 30. Further, on the side of the reverse edge (reverse edge) 37 opposite to the edge 36 of the opening 30c, there is a position for engaging with a substantially flat circuit board housing part 39a and a concave part 99 formed on the both sides of the flexible circuit board F. A circuit board disposing portion comprising the engaging protrusions 39b is configured.
[0014]
The process of automatically assembling and connecting the flexible circuit board connector and the flexible circuit board F will be described below in order.
[0015]
In the first step of assembly connection, the flexible circuit board F is disposed on the top surface 30 d of the insulating housing 30 in the temporary locking position of the plug member 70. At this time, since the concave portion 99 of the flexible circuit board F and the pair of protrusions 39b of the insulating housing 30 are engaged, the flexible circuit board is accurately arranged at a predetermined position.
[0016]
FIG. 2 shows the flexible circuit board F arranged at a predetermined position. In the second step of assembly connection, the plug member 70 is shown from the temporary locking position shown in FIG. 2 to the final locking position shown in FIG. 3 in the direction of arrow R. As shown in FIG. 2, the plug member 70 includes a first surface 70a, a second surface 70b substantially orthogonal to the first surface 70a, a protrusion 70c provided at a position facing the second surface 70b, and the protrusion 70c. It has the 3rd surface 70d located and the 4th surface 70e in the position facing the 1st surface 70a. As shown in FIG. 2, in the temporary locking position, the plug member 70 is placed upright so that the first surface 70a faces in a substantially vertical direction and the second surface 70b faces in a substantially horizontal direction. The first surface 70a can function as a stopper surface that determines the end position of the flexible circuit board F as shown in FIG. Further, the second surface 70b extending in the horizontal direction constitutes a suction surface for sucking the flexible circuit board connector 10 to the suction device so that the flexible circuit board connector 10 is automatically arranged at a predetermined position of the circuit board. The third surface 70d substantially abuts on the tongue 55b of the contact 50.
[0017]
FIG. 3 shows a state in which the plug device 70 is being rotated. In the course of rotation, the first surface 70a and the curved surface 70f positioned at the boundary between the first surface 70a and the second surface 70b push the flexible circuit board F into the opening 30c. As shown in the drawing, the third surface 70 d along the protrusion 70 c of the plug member 70 abuts against the tongue-like portion 55 b of the contact 50 even in the middle of rotation.
[0018]
FIG. 4 shows the plug member 70 in the fully locked position where the rotation is completed. In the process from the temporary locking position to the final locking position, the plug member 70 is rotated by approximately 90 °, and the arm 72 of the plug member 70 is received in the recess 33. When the plug member 70 reaches the full locking position, the claw 34 engages with an engagement shoulder (not shown) formed in the plug member 70, whereby the plug member 70 is maintained in the full locking position. When the plug member 70 is in the final locking position, the flexible circuit board F is elastically sandwiched between the contact arm 56 of the contact 50 and the second surface 70b of the plug member 70, and via the contact protrusion 56b. Electrically connected. The connected flexible circuit board F is guided by the guide piece 78 of the plug member 70 and extends laterally (horizontal direction). The plug support arm 55 of the contact 50 elastically contacts the projection 70c of the plug member 70 at a position facing the contact projection 56b, and supports the plug member 70. Since the shaft support means of the plug member 70 has some play, the plug member 70 and the flexible circuit board F are elastically sandwiched between the contact arm 56 of the contact 50 and the plug support arm 55, whereby the flexible circuit. A stable electrical connection between the plate F and the contacts 50 is provided. In the process in which the plug member 70 rotates from the temporary locking position to the final locking position, the third surface 70d along the protrusion 70c of the plug member 70 is in a position that is almost always in contact with the tongue 55b. As a result, the protrusion 70c of the plug member 70 can smoothly enter the lower position of the tongue-like portion 55b of the contact 50, and there is no need to apply unnecessary force to the plug support arm 55.
[0019]
As understood from FIG. 4, when the plug member 70 is in the final locking position, the fourth surface 70 e is substantially flush with the top surface 30 d of the insulating housing 30. Therefore, in order to rotate the plug member 70 in the rotation process of the plug member 70 shown in FIGS. 2 to 4 (in FIG. 3, the direction of rotation is indicated by an arrow R), a Tr as shown in FIG. A rotational force may be applied, or a pressing force by a member that slides linearly may be applied, such as Fs shown in FIG. In the latter case, the plug member 70 can be completely rotated to the full locking position by sliding a part of the sliding member at a position close to the top surface 30d.
[0020]
As described above, the flexible circuit board connector according to the preferred embodiment of the present invention has been described. However, this does not limit the present invention, and various modifications can be made by those skilled in the art.

【The invention's effect】
According to the connector for a flexible circuit board of the present invention, a circuit board arrangement in which a substantially rectangular opening is formed on one surface of an insulating housing that accommodates a plurality of contacts, and the flexible circuit board is aligned and arranged on one edge side of the opening. A flexible plug is provided in the circuit board arrangement portion by providing a portion and locking the plug member that can rotate with respect to the insulating housing on the opposite edge side, and rotating the plug member toward the main locking position. Since the circuit board is configured to be pushed into the opening of the insulating housing, the connection assembly of the flexible circuit board and the connector can be easily performed by the automatic assembly apparatus. In particular, since the flexible circuit board can be arranged and connected at a predetermined position, the connection reliability is high, and the plug member can be stably maintained on the insulating housing until connection assembly. In addition, an effective wiping action can be performed at the time of connection with the flexible circuit board by turning the plug member, so that a reliable electrical connection is realized.
