Description

【０００１】
【発明の属する技術分野】
この発明は、フレクシブルフラットケーブル（ＦＦＣ）やフレクシブルプリント基板（ＦＰＣ）等の扁平導体をプリント基板に接続するための扁平導体用コネクタに関するものである。
【０００２】
【従来の技術】
従来、この種の扁平導体用コネクタとしては、例えば特開２００１−２５７０２０号公報に開示された技術がある。
この技術は、図１０に示すように、ハウジング１００内に列設された接触端子１０１に扁平導体２００を直接挿入し、ハウジング１００に回動自在に取り付けられた操作部材１０２を下方に閉じることで、扁平導体２００を接触端子１０１の突起部１０１ａに押しつける構造になっている。
また、扁平導体用コネクタの他の例として、特開２００２−６３９５９号公報や米国特許４，７１８，８５９号公報に開示された技術がある。
この技術は、図１１に示すように、操作部材１０２に扁平導体２００用の挿入口１０２ａを設け、扁平導体２００をこの挿入口１０２ａに予め挿入した後、操作部材１０２を下方に閉じることで、扁平導体２００を接触端子１０１の突起部１０１ａに押し付ける構造となっている。
【０００３】
【発明が解決しようとする課題】
しかし、上記した従来の扁平導体用コネクタでは、次のような問題がある。
図１０に示した扁平導体用コネクタでは、扁平導体２００を接触端子１０１に直接挿入した後、操作部材１０２を閉じる構造であるので、扁平導体２００と接触端子１０１との位置ズレが生じ易く、接触不良が生じ易い。
また、接触端子１０１の突起部１０１ａが扁平導体２００を介して操作部材１０２を上方に押し、操作部材１０２を開けようとする。このため、操作部材１０２の閉状態を維持するために、ハウジング１００と操作部材１０２との両端部にロック機構１１０を設けている。しかし、ロック機構１１０が操作部材１０２の両端部のみを係止する機構であるので、図１２に示すように、操作部材１０２の中央部分が接触端子１０１の押上力によって上方に撓み、扁平導体２００と接触端子１０１との接触不良が生じ易い。
【０００４】
一方、図１１に示した扁平導体用コネクタでは、扁平導体２００を操作部材１０２の挿入口１０２ａに予め挿入した状態で、操作部材１０２を閉じる構造であるので、扁平導体２００と接触端子１０１との位置ズレによる接触不良のおそれは少ない。
しかし、この扁平導体用コネクタも、操作部材１０２の閉状態を維持するためのロック機構が操作部材１０２の両端部のみを係止する機構であるので、上記図１０に示した扁平導体用コネクタと同様に操作部材１０２の中央部分が上に撓んで接触不良を生じ易いという問題点を有している。
【０００５】
この発明は上述した課題を解決するためになされたもので、操作部材全体を均等にロックして、扁平導体と複数の接触端子との接触を確実に維持することができる扁平導体用コネクタを提供することを目的とするものである。
【０００６】
【課題を解決するための手段】
上記課題を解決するために、請求項１の発明は、開口を有するハウジングと、先端側を当該開口に向けてハウジング内に列設され且つハウジングの上面部側に位置するアーム部及び下面部側に位置するガイド部を有した複数の接触端子と、扁平導体を挿入するための受入口部及び接触端子のアーム部とガイド部との間に回動自在に遊嵌されたカム部を有する操作部材と、を具備する扁平導体用コネクタであって、各接触端子のガイド部は、ハウジングの奥に向かってせり上がる傾斜部を有し、各接触端子のアーム部は、傾斜部の頂部よりもハウジングの開口側に偏位して扁平導体側を向く扁平導体接触用突部を有し、操作部材のカム部は、受入口部に挿入された扁平導体を支持する上面部と、操作部材の開時にガイド部の傾斜部に当接する前面部と、当該前面部下位に設けられ且つ操作部材の閉時に傾斜部の頂部に乗り上がる角部とを有する構成とした。
かかる構成により、カム部の前面部が各接触端子のガイド部の傾斜部に当接している操作部材の開時において、扁平導体を受入口部から挿入すると、扁平導体がカム部の上面部で支持される。この状態で、操作部材を閉じながらハウジングの奥側に押圧していくと、カム部がガイド部上を登る。そして、操作部材の閉時には、カム部の角部が傾斜部の頂部に乗り上がる。この結果、カム部の上面に支持された扁平導体が接触端子のアーム部の扁平導体接触用突部に圧接されて下方力を受けると共に、カム部がガイド部の頂部から上方力を受ける。このとき、各接触端子のアーム部の扁平導体接触用突部が、傾斜部の頂部よりもハウジングの開口側に偏位して設定されているので、操作部材全体は閉じる方向に力を受ける。
【０００７】
特に、請求項２の発明は、請求項１に記載の扁平導体用コネクタにおいて、各接触端子のガイド部は、ハウジングの開口近傍に立設され、操作部材の閉操作時に、カム部の後面部に接触しながら当該カム部をハウジングの奥側に押し込むガイド突起を有する構成とした。
かかる構成により、操作部材の閉操作時には、カム部の後面部が各接触端子のガイド部のガイド突起に接触し、当該カム部がハウジングの奥側に押し込まれる。
【０００８】
また、請求項３の発明は、請求項１または請求項２に記載の扁平導体用コネクタにおいて、操作部材の両側部に軸部を突設すると共にハウジングの両側部に軸受部を設け、当該軸受部に操作部材の軸部を回動自在に遊嵌した構成としてある。
【０００９】
【発明の実施の形態】
以下、この発明の実施の形態について図面を参照して説明する。
図１は、この発明の一実施形態に係る扁平導体用コネクタを示す斜視図であり、図２は、操作部材の閉時の状態を示す斜視図であり、図３は、扁平導体用コネクタの底面側を示す斜視図である。
図１〜図３に示すように、この扁平導体用コネクタは、ハウジング１と複数の接触端子２と操作部材３とを具備している。
【００１０】
ハウジング１は、上面部１ａと下面部１ｂと両側の側面部１ｃとで構成され、その前面には、開口１０が形成されている。そして、ハウジング１の両側端部には、軸受部１１が設けられている。
図４及び図５は、図２の矢視Ａ−Ａ断面図である。
これらの図に示すように、ハウジング１の側面部の切欠き１１ａに固定金具１１ｂを圧着することで、軸受部１１を画成している。
【００１１】
接触端子２は、図１〜図３に示すように、先端部側をハウジング１側に向けてハウジング１内に等間隔で複数列設されている。
図６は、図２の矢視Ｂ−Ｂ断面図である。
図６に示すように、各接触端子２は、ハウジング１の下面部１ｂ側に位置するガイド部２０と上面部１ａ側に位置するアーム部２１とを有している。
【００１２】
ガイド部２０は、ハウジング１の開口１０近傍に突設されたガイド突起２２と、このガイド突起２２の奥側に形成された傾斜部２３とを有している。傾斜部２３は、ハウジング１の奥側に向かってせり上がり、接触端子２全体の略中央位置に頂部２４を有している。
【００１３】
一方、アーム部２１は、ガイド部２０と一体に形成され、上面部１ａに沿って開口１０側に延出している。
このアーム部２１の先端下側には、扁平導体接触用突部２５が突設されている。この扁平導体接触用突部２５の突設位置は、傾斜部２３の頂部２４の位置よりも距離ｔだけ開口１０側に偏位している。
【００１４】
操作部材３は、上記接触端子２の間に回動自在に嵌められた部材であり、その両端部には、軸部３０が突設されている。
具体的には、図４に示すように、軸部３０が操作部材３の先端部側に設けられ、ハウジング１の軸受部１１内に回動自在に遊嵌されている。なお、軸受部１１の固定金具１１ｂと切欠き１１ａとの間隙１１ｃは、軸部３０の直径よりも狭く設定され、軸部３０が軸受部１１から抜けないようになっている。
このようにして、ハウジング１に回動自在に取り付けられた操作部材３は、図６に示すように、扁平導体２００を挿入するための受入口部３１と、接触端子２のガイド部２０とアーム部２１との間に回動自在に遊嵌されたカム部３２とを有している。
【００１５】
カム部３２は、平面状の上面部３３及び前面部３４と、角部３５と、若干湾曲した後面部３６とを有している。
上面部３３は、操作部材３の受入口部３１から挿入された扁平導体２００を指示する部分であり、前面部３４は、カム部３２の後方に傾斜し、操作部材３の開時に接触端子２の傾斜部２３が当接するように設定されている。また、角部３５は、前面部３４の下位に設けられた鈍角部分である。後面部３６は、緩やかな曲面をなすが、その上端と前面部３４の上端との距離Ｄがガイド突起２２と頂部２４との距離ｄよりも大きく設定され、後面部３６がガイド突起２２に必ず接触するようになっている。
【００１６】
次に、この扁平導体用コネクタが示す作用について説明する。
まず、図６に示すように、操作部材３を上方に回動させて開き、カム部３２の前面部３４を接触端子２のガイド部２０の傾斜部２３に当接させると、後面部３６がガイド突起２２に当たって、操作部材３が開状態を保持する。
そして、扁平導体２００を操作部材３の受入口部３１に挿入すると、扁平導体２００がカム部３２の上面部３３に載置される。
【００１７】
次に、上記状態から、図７に示すように、操作部材３を下方に回動させて閉じていくと、ガイド部２０のガイド突起２２がカム部３２の後面部３６を接触端子２の奥側に押す状態になる。すなわち、操作部材３のかかる閉操作時においては、ガイド突起２２がカム部３２を接触端子２の奥側に押し込み、カム部３２の角部３５がガイド部２０の傾斜部２３に接触しながら、頂部２４側に登っていく。これと並行して、カム部３２の上面部３３に支持された扁平導体２００が接触端子２のアーム部２１を押し上げていく。
【００１８】
最後に、図８に示すように、カム部３２の角部３５が頂部２４に乗り上がると、操作部材３が完全に閉じた状態になると共に操作部材３が接触端子２の水平段部２６に当接する。
かかる閉時においては、扁平導体２００がアーム部２１の扁平導体接触用突部２５から下方力Ｆ１を受け、カム部３２がガイド部２０の頂部２４から角部３５を介して上方力Ｆ２を受けた状態になる。
このとき、扁平導体２００と扁平導体接触用突部２５との接触位置が頂部２４と角部３５との接触位置よりもハウジング１の開口１０側に偏位しているので、下方力Ｆ１と上方力Ｆ２とが共同して操作部材３を閉じる方向に回動させようする。同時に、接触端子２の水平段部２６がストッパとして機能して、操作部材３を略水平に支持する。この結果、操作部材３は各接触端子２によって完全にロックされた状態になる。
【００１９】
ところで、接触端子２は、図１に示すように、ハウジング１内に等間隔で複数列設されているので、図９に示すように、操作部材３全体が複数の接触端子２によって均等にロックされる。したがって、上述した従来の扁平導体用コネクタのように、操作部材３の中央部分が上方に撓んで接触不良を起こす事態は生じない。
【００２０】
このように、この実施形態の扁平導体用コネクタによれば、操作部材３の閉時に、複数の接触端子２が操作部材３全体を均等にロックするので、扁平導体２００と接触端子２のアーム部２１との電気的接触が確実に維持されるという効果がある。
【００２１】
【発明の効果】
以上詳しく説明したように、この発明によれば、操作部材の閉時に、複数の接触端子が操作部材全体を閉じる方向に作用するので、特別なロック機構を設けることなく、操作部材全体を均等にロックすることができ、この結果、扁平導体と複数の接触端子との接触を確実に維持することができるという優れた効果がある。
特に、接触端子のガイド部にガイド突起を設け、操作部材の閉操作時に、このガイド突起がカム部の後面部に接触しながら当該カム部をハウジングの奥側に押し込む構成とすることで、操作部材の操作を容易且つ正確に行うことができる。

BACKGROUND OF THE INVENTION
The present invention relates to a flat conductor connector for connecting a flat conductor such as a flexible flat cable (FFC) or a flexible printed circuit board (FPC) to a printed circuit board.
[0002]
[Prior art]
Conventionally, as this type of flat conductor connector, for example, there is a technique disclosed in Japanese Patent Laid-Open No. 2001-257020.
In this technique, as shown in FIG. 10, the flat conductor 200 is directly inserted into the contact terminals 101 arranged in the housing 100, and the operation member 102 rotatably attached to the housing 100 is closed downward. The flat conductor 200 is pressed against the protrusion 101 a of the contact terminal 101.
Other examples of the flat conductor connector include techniques disclosed in Japanese Patent Application Laid-Open No. 2002-63959 and US Pat. No. 4,718,859.
In this technique, as shown in FIG. 11, the operation member 102 is provided with an insertion port 102a for the flat conductor 200, and after the flat conductor 200 is inserted into the insertion port 102a in advance, the operation member 102 is closed downward. The flat conductor 200 is pressed against the protrusion 101 a of the contact terminal 101.
[0003]
[Problems to be solved by the invention]
However, the conventional flat conductor connector described above has the following problems.
The flat conductor connector shown in FIG. 10 has a structure in which the operation member 102 is closed after the flat conductor 200 is directly inserted into the contact terminal 101, so that the positional deviation between the flat conductor 200 and the contact terminal 101 is likely to occur. Defects are likely to occur.
Further, the protruding portion 101 a of the contact terminal 101 pushes the operation member 102 upward through the flat conductor 200 to open the operation member 102. For this reason, in order to maintain the closed state of the operation member 102, lock mechanisms 110 are provided at both ends of the housing 100 and the operation member 102. However, since the lock mechanism 110 is a mechanism that locks only both ends of the operation member 102, the central portion of the operation member 102 is bent upward by the push-up force of the contact terminal 101 as shown in FIG. And contact failure between the contact terminals 101 are likely to occur.
[0004]
On the other hand, the flat conductor connector shown in FIG. 11 has a structure in which the operation member 102 is closed in a state in which the flat conductor 200 is inserted into the insertion port 102a of the operation member 102 in advance. There is little risk of contact failure due to misalignment.
However, since this flat conductor connector is also a mechanism in which the lock mechanism for maintaining the closed state of the operation member 102 is a mechanism for locking only both ends of the operation member 102, the flat conductor connector shown in FIG. Similarly, there is a problem in that the central portion of the operation member 102 is bent upward to easily cause a contact failure.
[0005]
The present invention has been made to solve the above-described problem, and provides a flat conductor connector that can uniformly lock the entire operation member and reliably maintain contact between the flat conductor and the plurality of contact terminals. It is intended to do.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a first aspect of the present invention is a housing having an opening, and an arm portion and a lower surface portion side that are arranged in the housing with the front end side facing the opening and located on the upper surface portion side of the housing. An operation having a plurality of contact terminals having guide portions located in the center, a receiving portion for inserting a flat conductor, and a cam portion freely fitted between the arm portion and the guide portion of the contact terminal. A guide for each contact terminal, the guide portion of each contact terminal has an inclined portion that rises toward the back of the housing, the arm portion of each contact terminal is more than the top of the inclined portion There is a flat conductor contact projection that is displaced toward the opening side of the housing and faces the flat conductor, and the cam portion of the operation member includes an upper surface portion that supports the flat conductor inserted into the receiving portion, and Before contacting the inclined part of the guide part when opening And parts, and configured to have a corner portion rides on top of the closed to the inclined portion of and the operating member provided on the lower the front portion.
With this configuration, when the flat conductor is inserted from the receiving portion when the operation member in which the front surface portion of the cam portion is in contact with the inclined portion of the guide portion of each contact terminal is opened, the flat conductor is formed on the upper surface portion of the cam portion. Supported. In this state, when the operation member is closed and pressed toward the back side of the housing, the cam portion climbs on the guide portion. When the operation member is closed, the corner portion of the cam portion rides on the top portion of the inclined portion. As a result, the flat conductor supported on the upper surface of the cam portion is pressed against the flat conductor contact protrusion of the arm portion of the contact terminal and receives a downward force, and the cam portion receives an upward force from the top of the guide portion. At this time, since the flat conductor contact protrusions of the arm portions of the contact terminals are set so as to be displaced from the top of the inclined portion toward the opening side of the housing, the entire operation member receives a force in the closing direction.
[0007]
Particularly, the invention according to claim 2 is the flat conductor connector according to claim 1, wherein the guide portion of each contact terminal is erected in the vicinity of the opening of the housing, and the rear surface portion of the cam portion is closed when the operation member is closed. The cam part has a guide protrusion that pushes the cam part into the back side of the housing while being in contact with the housing.
With this configuration, when the operation member is closed, the rear surface portion of the cam portion comes into contact with the guide protrusion of the guide portion of each contact terminal, and the cam portion is pushed into the back side of the housing.
[0008]
According to a third aspect of the present invention, in the flat conductor connector according to the first or second aspect of the present invention, the shaft portion protrudes from both sides of the operation member and the bearing portion is provided at both sides of the housing. The shaft portion of the operation member is loosely fitted to the portion so as to be freely rotatable.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a perspective view showing a flat conductor connector according to an embodiment of the present invention, FIG. 2 is a perspective view showing a closed state of an operation member, and FIG. 3 is a view of the flat conductor connector. It is a perspective view which shows a bottom face side.
As shown in FIGS. 1 to 3, the flat conductor connector includes a housing 1, a plurality of contact terminals 2, and an operation member 3.
[0010]
The housing 1 includes an upper surface portion 1a, a lower surface portion 1b, and side surface portions 1c on both sides, and an opening 10 is formed on the front surface thereof. And the bearing part 11 is provided in the both-sides edge part of the housing 1. As shown in FIG.
4 and 5 are sectional views taken along line AA in FIG.
As shown in these drawings, a bearing 11 is defined by crimping a fixing metal 11b to a notch 11a on a side surface of the housing 1.
[0011]
As shown in FIGS. 1 to 3, the contact terminals 2 are provided in a plurality of rows at equal intervals in the housing 1 with the tip end side facing the housing 1.
6 is a cross-sectional view taken along the line BB in FIG.
As shown in FIG. 6, each contact terminal 2 has a guide portion 20 located on the lower surface portion 1 b side of the housing 1 and an arm portion 21 located on the upper surface portion 1 a side.
[0012]
The guide portion 20 includes a guide protrusion 22 that protrudes in the vicinity of the opening 10 of the housing 1 and an inclined portion 23 that is formed on the back side of the guide protrusion 22. The inclined portion 23 rises toward the back side of the housing 1 and has a top 24 at a substantially central position of the entire contact terminal 2.
[0013]
On the other hand, the arm portion 21 is formed integrally with the guide portion 20 and extends toward the opening 10 along the upper surface portion 1a.
A flat conductor contact protrusion 25 is provided on the lower side of the tip of the arm 21. The projecting position of the flat conductor contact projecting portion 25 is shifted to the opening 10 side by a distance t from the position of the top portion 24 of the inclined portion 23.
[0014]
The operation member 3 is a member that is rotatably fitted between the contact terminals 2, and shaft portions 30 are projected from both ends thereof.
Specifically, as shown in FIG. 4, the shaft portion 30 is provided on the distal end side of the operation member 3 and is loosely fitted in the bearing portion 11 of the housing 1 so as to be freely rotatable. The gap 11c between the fixing bracket 11b of the bearing portion 11 and the notch 11a is set to be narrower than the diameter of the shaft portion 30 so that the shaft portion 30 cannot be removed from the bearing portion 11.
In this way, the operation member 3 rotatably attached to the housing 1 includes a receiving portion 31 for inserting the flat conductor 200, a guide portion 20 of the contact terminal 2, and an arm as shown in FIG. And a cam portion 32 that is rotatably fitted between the portion 21 and the portion 21.
[0015]
The cam portion 32 has a flat upper surface portion 33 and a front surface portion 34, a corner portion 35, and a slightly curved rear surface portion 36.
The upper surface portion 33 is a portion indicating the flat conductor 200 inserted from the receiving port portion 31 of the operation member 3, and the front surface portion 34 is inclined rearward of the cam portion 32, and the contact terminal 2 is opened when the operation member 3 is opened. The inclined portion 23 is set so as to abut. Further, the corner portion 35 is an obtuse angle portion provided below the front surface portion 34. The rear surface portion 36 has a gentle curved surface, but the distance D between the upper end of the rear surface portion 36 and the upper end of the front surface portion 34 is set to be larger than the distance d between the guide projection 22 and the top portion 24, and the rear surface portion 36 is always on the guide projection 22. It comes to contact.
[0016]
Next, the operation of the flat conductor connector will be described.
First, as shown in FIG. 6, when the operation member 3 is rotated upward to open and the front surface portion 34 of the cam portion 32 is brought into contact with the inclined portion 23 of the guide portion 20 of the contact terminal 2, the rear surface portion 36 is moved. The operation member 3 is held in the open state by hitting the guide protrusion 22.
When the flat conductor 200 is inserted into the receiving port 31 of the operation member 3, the flat conductor 200 is placed on the upper surface portion 33 of the cam portion 32.
[0017]
Next, from the above state, as shown in FIG. 7, when the operating member 3 is rotated downward and closed, the guide protrusion 22 of the guide portion 20 causes the rear surface portion 36 of the cam portion 32 to move behind the contact terminal 2. It will be pushed to the side. That is, during the closing operation of the operation member 3, the guide protrusion 22 pushes the cam portion 32 into the back side of the contact terminal 2, and the corner portion 35 of the cam portion 32 contacts the inclined portion 23 of the guide portion 20. Climb to the top 24 side. In parallel with this, the flat conductor 200 supported by the upper surface portion 33 of the cam portion 32 pushes up the arm portion 21 of the contact terminal 2.
[0018]
Finally, as shown in FIG. 8, when the corner portion 35 of the cam portion 32 rides on the top portion 24, the operation member 3 is completely closed and the operation member 3 is moved to the horizontal step portion 26 of the contact terminal 2. Abut.
When closed, the flat conductor 200 receives the downward force F1 from the flat conductor contact protrusion 25 of the arm portion 21, and the cam portion 32 receives the upward force F2 from the top portion 24 of the guide portion 20 via the corner portion 35. It becomes a state.
At this time, since the contact position between the flat conductor 200 and the flat conductor contact protrusion 25 is shifted to the opening 10 side of the housing 1 with respect to the contact position between the top 24 and the corner 35, the downward force F1 and the upward force Together with the force F2, the operation member 3 is rotated in the closing direction. At the same time, the horizontal step portion 26 of the contact terminal 2 functions as a stopper, and supports the operation member 3 substantially horizontally. As a result, the operation member 3 is completely locked by the contact terminals 2.
[0019]
By the way, since the contact terminals 2 are arranged in a plurality of rows at equal intervals in the housing 1 as shown in FIG. 1, the entire operation member 3 is evenly locked by the plurality of contact terminals 2 as shown in FIG. Is done. Therefore, unlike the above-described conventional flat conductor connector, a situation in which the central portion of the operation member 3 is bent upward and poor contact does not occur.
[0020]
Thus, according to the flat conductor connector of this embodiment, when the operation member 3 is closed, the plurality of contact terminals 2 evenly lock the entire operation member 3. There exists an effect that the electrical contact with 21 is maintained reliably.
[0021]
【The invention's effect】
As described above in detail, according to the present invention, when the operating member is closed, the plurality of contact terminals act in a direction to close the entire operating member, so that the entire operating member can be evenly provided without providing a special locking mechanism. As a result, there is an excellent effect that the contact between the flat conductor and the plurality of contact terminals can be reliably maintained.
In particular, the guide terminal of the contact terminal is provided with a guide protrusion, and when the operation member is closed, the guide protrusion is in contact with the rear surface of the cam part, and the cam part is pushed into the back of the housing. The operation of the member can be performed easily and accurately.
