Description

【０００１】
【発明の属する技術分野】
本発明は、主として導電性パターンが形成された基板間同士の高密度な接続用に供される電気コネクタであって、詳しくは機械的強度を確保して糸状部材による複数のコンタクトが高密度にして高精度に配備された構造の電気コネクタに関する。
【０００２】
【従来の技術】
従来、この種の高密度なコンタクトを備えた電気コネクタの一例としては、経糸及び緯糸の一方に導電性繊維と弾力性に富んだ絶縁性繊維とを用い、且つ他方に絶縁性繊維のみを用いるか、或いは経糸及び緯糸の一方に導電性繊維のみを用い、且つ他方に弾力性に富んだ絶縁性繊維のみを用いるものとした上、これらのコンタクトとしての導電性繊維、及びインシュレータとしての絶縁性繊維を交互に編んだ構造の異方性導電布（特許文献１）が挙げられる。
【０００３】
又、同様な電気コネクタの他例としては、導電性の線材を三次元方向に繊り上げた三次元繊物体を筐体兼端子板となるケース内に収設し、各線材の端部をケースを構成している外壁板の対応する各端子に接続することで三次元繊物体における各線材の任意の交点を接点又は非接点とする構造の電気機器の接続基体（特許文献２）が挙げられる。

【発明が解決しようとする課題】
上述した特許文献１の異方性導電布の場合、コンタクトとしての導電性繊維、及びインシュレータとしての絶縁性繊維を交互に編んだ構造であるため、作製時に繊維を編むときの密度を一定にしながらピッチ寸法を一様に保つことが困難である（特に繊維に潰れ等があるとコンタクトを高精度に配備し難い）ことにより、生産性が悪くなってしまうばかりでなく、仕上がりとして機械的強度を確保した上でコンタクトを高密度にして高精度に配備することが困難になっているという問題がある。
【０００７】
又、特許文献２の電気機器の接続基体の場合においても、基本的に三次元繊物体の作製に用いられる導電性の線材の繊り上げに手間がかかると共に、ケースを構成している外壁板に設けられる端子の密度が高くて端子部品の総数も膨大になって複雑な構造となることを回避できないためにケースの作製にも手間がかかってしまう上、三次元繊物体における各線材の端部をケースの膨大な数の端子に接続した上で三次元繊物体の各線材の任意の交点を接点又は非接点とする構造であることにより、全体の作製に際して特許文献１の場合と比べて更に生産性が悪くなり、結果として同様に機械的強度を確保した上でコンタクトを高密度にして高精度に配備することが困難になっている他、この場合には外観上でケースにおける各端子が接点用のものか非接点用のものかを容易に識別し難い構造となるために取り扱いが不便であるという問題もある。
【０００８】
本発明は、このような問題点を解決すべくなされたもので、その技術的課題は、機械的強度を確保した上でコンタクトが高密度にして高精度に配備された構造の電気コネクタを提供することにある。

【００１４】
この電気コネクタにおいて、複数本の絶縁線は、板状基体における一対のハウジング基体の一方のものに対する複数のロケータの組み付けに応じて複数の切り欠き部と該複数の切り欠き部同士が当接されて形成される複数の貫通孔とに対して垂直方向に配列されるものの一つおきに一方向の列としてそれぞれ位置決めされるように先端側を取り付けてから後続する隣り合うロケータにおける該複数の切り欠き部同士が当接されて形成される該複数の貫通孔に対して中途部分を該一方向の列に沿うように順次くぐらせて装着されたことは好ましく、更にこの電気コネクタにおいて、複数本の絶縁線は、複数のロケータのうちの一対のハウジング基体の一方のもの寄りのものにおける複数の切り欠き部に対して先端側が一つおきに一方向の列として取り付けられる第１の絶縁線、並びに該複数の切り欠き部の垂直方向における反対側のものに対して隣り合うロケータにおける該複数の切り欠き部が当接されて形成される複数の貫通孔に対して先端側が一つおきに別な一方向の列として取り付けられる第２の絶縁線として区別されることは好ましい。

【発明の実施の形態】
以下に本発明の実施の形態について、図面を参照して詳細に説明する。図１は、本発明の一つの実施の形態に係る電気コネクタの基本構造を示した外観斜視図である。
【００１７】
この電気コネクタは、技術的概要として、両方の主面を貫通するように複数の貫通孔が一方向に延びて所定の間隔で形成され、且つ同一平面上で一方向とは垂直な垂直方向（以下も同様な旨を示すものとする）にも近接して延びて格子状に配列されるように形成された絶縁性の板状基体２と、板状基体２における各貫通孔に対してそれぞれ装着されて両方の主面のうちの一方の主面と他方の主面とに対して揃って露呈されることで平坦な基板面の導電性パターンにおける複数箇所に接触可能であると共に、近接するもの同士がそれぞれ非接触となるように波状に配置された糸状部材による複数のコンタクトとを有している。
【００１８】
具体的に言えば、複数のコンタクトは、各貫通孔に対して一方向に配列されたもの毎に両方の主面のうちの一方の主面側から他方の主面側へと順次連続的にくぐらせて板状基体２における一方向に延びた帯状局部毎に介装される複数本（ここでは１０本）の絶縁線１における表面にメッキ等の表面処理によりそれぞれ所定の間隔を持たせて設けられた複数の導電膜１ａから成るものである。即ち、ここでの各絶縁線１は、各導電膜１ａ間に絶縁部１ｂが露呈されることにより、その表面に導電膜１ａと絶縁部１ｂとが交互に配置されるもので、各貫通孔への装着に際しては、一方向に配列されたもの毎（ここでは１０列分に１０本を要することを示す）に介装された状態で各導電膜１ａの両端部がそれぞれ板状基体２における両方の主面のうちの一方の主面と他方の主面とに対して揃って露呈されることで平坦な基板面の導電性パターンにおける複数箇所に接触可能に配置されると共に、各導電膜１ａの両端部の一方向に配列されたものにあっての垂直方向で近接するもの同士がそれぞれ非接触となるように配置されている。
【００１９】
又、板状基体２は、一方向の両側に配置される垂直方向に延在した一対のハウジング基体２ａと、これらの一対のハウジング基体２ａの間で一対の位置決めシャフト３を用いて一方向にスライド可能に取り付けられると共に、互いに一方向で当接された状態で各貫通孔を形成可能であるように垂直方向に沿った両側にそれぞれ一様な形状（ここではＶ字状形状である場合を示すが、Ｕ字状形状とすることも可能である）の複数の切り欠き部４が設けられて成る垂直方向に延在した複数（ここでは４つ）のロケータ２ｂとを組み合わせて成るものである。

【００２１】
図２では、上述したように、一対のハウジング基体２ａ及び各ロケータ２ｂを組み合わせて成る板状基体２の各貫通孔に対して各絶縁線１をくぐらせて介装した状態で各絶縁線１における各導電膜１ａの両端部がそれぞれ板状基体２における両方の主面のうちの一方の主面（例えば配線基板５側）と他方の主面（例えば配線基板６側）とに対して揃って露呈されることで平坦な配線基板５，６面の導電性パターンにおける複数箇所に接触されるように配置され、且つ各導電膜１ａの両端部の一方向に配列されたものにあっての垂直方向で近接するもの同士がそれぞれ非接触となるように配置される様子を示している。

【００２３】
図３では、一対のハウジング基体２ａが各ロケータ２ｂを組み込む側の垂直方向に隔たった位置に一対の位置決めシャフト３を装着固定するための装着孔を有し、各ロケータ２ｂが各切り欠き部４を間に配置させて垂直方向に隔たった位置に一対の位置決めシャフト３を挿通させるための挿通孔を有しており、これによって、板状基体２が一対のハウジング基体２ａの一方のものの装着孔に一対の位置決めシャフト３の一端側をそれぞれ装着固定した状態で一対の位置決めシャフト３の中途部分に各ロケータ２ｂの挿通孔をそれぞれ通して順次各ロケータ２ｂを当接させて組み付けてから一対の位置決めシャフト３の他端側を一対のハウジング基体２ａの他方のものの装着孔にそれぞれ装着固定して構成されることを示している。
【００２４】
図４は、上述した板状基体２に対して各絶縁線１を取り付ける様子を示した分解斜視図である。
【００２５】
図４では、各絶縁線１が板状基体２における一対のハウジング基体２ａの一方のものに対する各ロケータ２ｂの組み付けに応じて各切り欠き部４と各切り欠き部４同士が当接されて形成される各貫通孔とに対して垂直方向に配列されるものをそれぞれ位置決めした上で各貫通孔の一方向に沿って取り付けられることを示している。
【００２６】
具体的に言えば、各絶縁線１は、板状基体２における一対のハウジング基体２ａの一方のものに対する各ロケータ２ｂの組み付けに応じて各切り欠き部４と各切り欠き部４同士が当接されて形成される各貫通孔とに対して垂直方向に配列されるものの一つおきに一方向の列としてそれぞれ位置決めされるように先端側を取り付けてから後続する隣り合うロケータ２ｂにおける各切り欠き部４同士が当接されて形成される各貫通孔に対して中途部分を一方向の列に沿うように順次くぐらせて装着されるものである。即ち、各絶縁線１は、図４に示されるように各ロケータ２ｂのうちの一対のハウジング基体２ａの一方のもの寄りのものにおける各切り欠き部４に対して先端側が一つおきに一方向の列として取り付けられる総計５本の第１の絶縁線を含む他、ここでの各切り欠き部４の垂直方向における反対側のものに対して隣り合うロケータ２ｂにおける各切り欠き部４が当接されて形成される各貫通孔に対して先端側が一つおきに別な一方向の列として取り付けられる図示されない総計５本の第２の絶縁線を有しており、総計１０本の配線が区別されて取り付けられることによって、図１に示したような構成が得られるようになっている。
【００２７】
このような構成の電気コネクタの場合、一対のハウジング基体２ａ間にスライド可能に複数のロケータ２ｂを配置して板状基体２を構成し、各ロケータ２ｂに設けられた各切り欠き部４と各切り欠き部４同士が当接されて形成される各貫通孔とを一様な形状で高精度に並設させるようにした上、各貫通孔に対して表面上に導電膜１ａと絶縁部１ｂとが交互に設けられて成る各絶縁線１を一方向に沿ってくぐらせてコンタクト（導電膜１ａ）を位置決めして取り付けするときに各ロケータ２ｂ間の各切り欠き部４周囲の壁面に各絶縁線１の表面が挟み込まれて安定して適確に狭ピッチ化配置を行うことができる（１本の絶縁線１で数芯分の接点を得られる）ため、各絶縁線１を取り付けての全体の組み付け作製時にコンタクトの密度を一定にしながらピッチ寸法を一様に保つことが容易であり、しかも各絶縁線１を一方向に沿って各貫通孔にくぐらせるように用いているために仕上がりとして機械的強度を確保した上でコンタクトを高密度にして高精度に配備することができ、全体の作製時の生産性も向上される。
【００２８】
【発明の効果】
以上に説明したように、本発明の電気コネクタによれば、一対のハウジング基体間にスライド可能に複数のロケータを配置して板状基体を構成し、各ロケータに設けられた各切り欠き部と各切り欠き部同士が当接されて形成される各貫通孔とを一様な形状で高精度に並設させるようにした上、これらの各貫通孔に対して表面上に導電膜と絶縁部とが交互に設けられて成る各絶縁線を一方向に沿ってくぐらせてコンタクトとしての導電膜を位置決めして取り付けするときに各ロケータ間の各切り欠き部周囲の壁面に各絶縁線の表面が挟み込まれて安定して適確に狭ピッチ化配置を行うことができる（１本の絶縁線１で数芯分の接点を得られる）ため、従来の特許文献１のような繊維を編む場合の構造とは異なり、各絶縁線を取り付けての全体の組み付け作製時にコンタクトの密度を一定にしながらピッチ寸法を一様に保つことが容易となり、しかも各絶縁線を一方向に沿って各貫通孔にくぐらせるように用いているために仕上がりとして機械的強度が確保されてコンタクトを高密度にして高精度に配備することができ、結果として全体の作製時における生産性も向上されるようになる。

BACKGROUND OF THE INVENTION
The present invention is an electrical connector mainly used for high-density connection between substrates on which conductive patterns are formed. Specifically, a mechanical strength is ensured, and a plurality of contacts made of thread-like members are made high-density. The present invention relates to an electrical connector having a structure arranged with high accuracy.
[0002]
[Prior art]
Conventionally, as an example of an electrical connector having such a high-density contact, one of warp and weft is made of conductive fiber and elastic insulating fiber, and the other is made of only insulating fiber. Or only one of the warp and weft is made of conductive fibers and the other is made of only insulating fibers rich in elasticity, and the conductive fibers as these contacts and the insulation as insulators. An anisotropic conductive cloth having a structure in which fibers are knitted alternately (Patent Document 1) can be mentioned.
[0003]
As another example of a similar electrical connector, a three-dimensional fiber object in which conductive wires are finely arranged in a three-dimensional direction is placed in a case serving as a housing and terminal plate, and the end of each wire is A connection base of an electric device having a structure in which an arbitrary intersection of each wire in a three-dimensional fiber object is a contact or non-contact by connecting to corresponding terminals of the outer wall plate constituting the case (Patent Document 2) is given.

[Problems to be solved by the invention]
In the case of the anisotropic conductive cloth of Patent Document 1 described above, since the structure is a structure in which conductive fibers as contacts and insulating fibers as insulators are alternately knitted, the density when the fibers are knitted at the time of production is kept constant. It is difficult to keep the pitch dimension uniform (especially, if the fibers are crushed, it is difficult to place the contact with high precision), not only the productivity will deteriorate, but also the mechanical strength as the finish will be reduced. There is a problem that it is difficult to arrange the contacts with high density with high accuracy after securing.
[0007]
Also, in the case of the connection base of the electric device of Patent Document 2, it is basically time-consuming to make a conductive wire used for producing a three-dimensional fiber object, and the outer wall plate constituting the case Since the density of terminals provided on the terminal is too high and the total number of terminal parts is too large to avoid a complicated structure, it is time-consuming to manufacture the case, and the end of each wire rod in the three-dimensional fiber object Compared with the case of patent document 1 in the whole manufacture by connecting the part to a huge number of terminals of the case and making an arbitrary intersection of each wire rod of the three-dimensional fiber object as a contact or non-contact In addition, the productivity deteriorates, and as a result, it is difficult to arrange the contacts with high density with high mechanical accuracy while ensuring mechanical strength. For contacts Or handling for either the easily identifiable hard structures intended for non-contact there is a problem that it is inconvenient.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an external perspective view showing a basic structure of an electrical connector according to one embodiment of the present invention.
[0017]
As a technical outline, this electrical connector has a plurality of through-holes extending in one direction so as to penetrate both main surfaces and formed at a predetermined interval, and a vertical direction perpendicular to the one direction on the same plane ( The following will also indicate the same), and the insulating plate-like substrate 2 formed so as to be closely arranged and arranged in a grid pattern, and each through-hole in the plate-like substrate 2 respectively. By being mounted and exposed to one main surface and the other main surface of both the main surfaces, it is possible to contact a plurality of locations in the conductive pattern on the flat substrate surface and to be close to each other It has the some contact by the thread-like member arrange | positioned in a wave shape so that things may become non-contact each.
[0018]
Specifically, the plurality of contacts are sequentially sequentially from one main surface side of both main surfaces to the other main surface side for each one arranged in one direction with respect to each through hole. The surface of the plurality of (in this case, 10) insulating wires 1 interposed between the strip-like local portions extending in one direction in the plate-like substrate 2 is provided with a predetermined interval by a surface treatment such as plating. It consists of a plurality of conductive films 1a provided. That is, each insulating wire 1 here is such that the insulating portions 1b are exposed between the respective conductive films 1a, whereby the conductive films 1a and the insulating portions 1b are alternately arranged on the surface thereof. At the time of mounting to the plate-shaped substrate 2, both ends of each conductive film 1 a are respectively inserted in one array arranged in one direction (here, 10 lines are required for 10 rows). Each of the main surfaces is arranged so as to be able to come into contact with a plurality of portions of the conductive pattern on the flat substrate surface by being exposed to one main surface and the other main surface, and each conductive film. The ones arranged in one direction at both ends of 1a are arranged so as to be in non-contact with each other adjacent in the vertical direction.
[0019]
Further, the plate-like base 2 is formed in one direction by using a pair of housing bases 2a extending in the vertical direction disposed on both sides in one direction and a pair of positioning shafts 3 between the pair of housing bases 2a. It is slidably mounted and has a uniform shape on both sides along the vertical direction so that each through-hole can be formed in a state of being in contact with each other in one direction (in this case, it is a V-shaped shape). As shown, it is formed by combining a plurality of (in this case, four) locators 2b extending in the vertical direction and provided with a plurality of notches 4 (which may be U-shaped). is there.
[0020]
FIG. 2 is a side cross-sectional view showing the connection arrangement structure when the wiring boards 5 and 6 are connected using this electrical connector corresponding to the internal structure of the cross section in the AA line direction in FIG. .
[0021]
In FIG. 2, as described above, each insulated wire 1 is inserted in a state where each insulated wire 1 passes through each through hole of the plate-like substrate 2 formed by combining a pair of housing bases 2 a and each locator 2 b. Both end portions of each conductive film 1a are aligned with respect to one main surface (for example, the wiring substrate 5 side) and the other main surface (for example, the wiring substrate 6 side) of both main surfaces of the plate-like substrate 2 respectively. It is arranged so as to be in contact with a plurality of places in the conductive pattern on the flat wiring boards 5 and 6 by being exposed, and arranged in one direction at both ends of each conductive film 1a. It shows a state in which those adjacent in the vertical direction are arranged so as not to contact each other.
[0022]
FIG. 3 is a perspective view showing the detailed structure of the plate-like substrate 2 used in the above-described electrical connector in an exploded state before each insulating wire 1 is attached.
[0023]
In FIG. 3, the pair of housing bases 2 a have mounting holes for mounting and fixing the pair of positioning shafts 3 at positions vertically spaced on the side where the locators 2 b are assembled, and each locator 2 b has each notch 4. Are disposed in the vertical direction and have a through hole through which the pair of positioning shafts 3 are inserted, so that the plate-like base body 2 has a mounting hole for one of the pair of housing base bodies 2a. With one end of each of the pair of positioning shafts 3 mounted and fixed to each other, the insertion holes of each locator 2b are passed through the middle portions of the pair of positioning shafts 3 so that the respective locators 2b are sequentially brought into contact with each other and assembled. It is shown that the other end side of the shaft 3 is mounted and fixed in the mounting holes of the other one of the pair of housing bases 2a.
[0024]
FIG. 4 is an exploded perspective view showing the manner in which each insulating wire 1 is attached to the plate-like substrate 2 described above.
[0025]
In FIG. 4, each notch portion 4 and each notch portion 4 are brought into contact with each other in accordance with the assembly of each locator 2b to one of the pair of housing bases 2a in the plate-like base 2 in FIG. It is shown that the components arranged in the vertical direction with respect to the respective through holes are positioned and attached along one direction of each through hole.
[0026]
Specifically, each notch 4 and each notch 4 come into contact with each other in accordance with the assembly of each locator 2b to one of the pair of housing bases 2a in the plate-like base 2. The notches in the adjacent locators 2b that follow after the tip side is attached so that every other one of the holes arranged in the vertical direction with respect to the formed through-holes is positioned as a row in one direction. The through-holes formed by abutting the portions 4 with each other are attached by passing through the intermediate portions sequentially along a line in one direction. That is, as shown in FIG. 4, each insulating wire 1 is in one direction at every other end side with respect to each notch portion 4 of one of the pair of housing bases 2a of each locator 2b. In addition to a total of five first insulated wires attached as a row, each notch 4 in adjacent locator 2b abuts on the other side in the vertical direction of each notch 4 here Each of the through holes formed in this way has a total of five second insulation wires (not shown) that are attached as alternate one-direction rows at every other tip side, and a total of ten wires are distinguished. Thus, the configuration as shown in FIG. 1 can be obtained.
[0027]
In the case of such an electrical connector, a plurality of locators 2b are slidably arranged between a pair of housing bases 2a to form a plate-like base 2, and each notch 4 provided in each locator 2b and each notch 4 are provided. The through holes formed by contacting the notches 4 with each other are arranged in a uniform shape with high accuracy, and the conductive film 1a and the insulating portion 1b are formed on the surface with respect to the through holes. When the contact (conductive film 1a) is positioned and attached by passing through the insulating wires 1 formed alternately with each other along the one direction, each of the wires is provided on the wall surface around each notch 4 between the locators 2b. Since the surface of the insulated wire 1 is sandwiched and the pitch can be arranged stably and accurately with a narrow pitch (one insulated wire 1 can provide contacts for several cores), each insulated wire 1 is attached. Keep the contact density constant during assembly It is easy to keep the pitch dimension uniform, and since each insulating wire 1 is used to pass through each through hole along one direction, the contact is made after ensuring the mechanical strength as the finish. It is possible to deploy with high density and high accuracy, and productivity at the time of overall production is also improved.
