【発明の属する技術分野】
本発明は、例えば各種電子機器の回路基板同士を接続するための基板接続用コネクタ及びコネクタ接続用基板に関するものである。
【０００２】
【従来の技術】
従来、例えばパーソナルコンピュータの回路基板同士を接続するためのコネクタとして、基板の接続部を挿入可能な基板挿入口を有する絶縁性のコネクタ本体と、コネクタ本体内に基板挿入口の長手方向に沿って配列された複数の端子とを備え、コネクタ本体の基板挿入口に基板の接続部を挿入することにより、各端子を基板の接続部に設けた複数の導電部にそれぞれ接触させるようにしたものが知られている（例えば、特許文献１参照。）。

【０００４】
【発明が解決しようとする課題】
ところで、前記従来例では、基板の各導電部をコネクタの端子配列方向に一列に配置しているため、多数の端子を高密度に配置したコネクタとの接続においては、各導電部の端子配列方向の長さ及び間隔を微小に形成しなければならない。このため、端子配列方向への基板の位置ずれに対する許容範囲を十分に確保することができず、隣接する導電部同士の短絡や接触不良を生じ易いという問題点があった。
【０００５】
本発明は前記問題点に鑑みてなされたものであり、その目的とするところは、端子を高密度に配置した場合でも、端子配列方向への基板の位置ずれに対する許容範囲を十分に確保することのできる基板接続用コネクタ及びコネクタ接続用基板を提供することにある。
【０００６】
【課題を解決するための手段】
本発明は前記目的を達成するために、請求項１では、接続対象物としての基板の接続部を挿入可能な基板挿入口を有する絶縁性のコネクタ本体と、コネクタ本体内に基板挿入口の長手方向に沿って配列された複数の端子とを備え、コネクタ本体の基板挿入口に基板の接続部を挿入することにより、各端子を基板の接続部に設けた複数の導電部にそれぞれ接触させるようにした基板接続用コネクタにおいて、前記各端子の基板との接触部を互いに隣接する接触部同士が基板の挿入方向に所定距離だけずれるように配置している。これにより、導電部をコネクタの各端子の接触部にそれぞれ対応するように互いに隣接する導電部同士がコネクタへの挿入方向に所定距離だけずれるように配置した基板と接続することにより、基板の各導電部の端子配列方向の長さを大きくすることができ、端子配列方向への基板の位置ずれに対する許容範囲を十分に確保することが可能となる。
【０００７】
また、請求項２では、請求項１記載の基板接続用コネクタにおいて、前記各端子を端子配列方向及び基板挿入方向に直交する方向に弾性変形可能に形成している。これにより、請求項１の作用に加え、前記方向への基板との位置ずれが各端子の弾性変形によって吸収される。
【０００８】
また、請求項３では、請求項２記載の基板接続用コネクタにおいて、前記コネクタ本体に各端子の前記弾性変形を許容する空間部を設けている。これにより、請求項２の作用に加え、空間部によって各端子がコネクタ本体と干渉することなく弾性変形する。
【０００９】
また、請求項４では、請求項１、２または３記載の基板接続用コネクタに接続されるコネクタ接続用基板であって、コネクタとの接続部に設けた複数の導電部をコネクタの各端子の接触部にそれぞれ対応するように互いに隣接する導電部同士がコネクタへの挿入方向に所定距離だけずれるように配置している。これにより、互いに隣接する導電部同士がコネクタへの挿入方向にずれていることから、基板の各導電部の端子配列方向の長さを大きくすることができ、請求項１、２または３記載の基板接続用コネクタと接続することにより、端子配列方向への基板の位置ずれに対する許容範囲を十分に確保することが可能となる。
【００１０】
また、請求項５では、請求項４記載のコネクタ接続用基板において、前記各導電部をコネクタの端子配列方向に延びるように形成するとともに、互いに隣接する導電部同士を互いの一部がコネクタへの挿入方向に間隔をおいてコネクタの端子配列方向に重なり合うように設けている。これにより、請求項４の作用に加え、互いに隣接する導電部同士がコネクタの端子配列方向に重なり合うように設けられていることから、各導電部を端子配列方向に長く形成することが可能となる。
【００１１】
【発明の実施の形態】
図１乃至図８は本発明の一実施形態を示すもので、図１はコネクタの上面側斜視図、図２はその側面断面図、図３はコネクタ及び基板の斜視図、図４はその接続状態を示す斜視図、図５はコネクタの側面断面図、図６及び図７はコネクタ及び基板の要部拡大正面図、図８はコネクタの側面断面図である。
【００１２】
同図に示すコネクタ１は、絶縁性のコネクタ本体２と、コネクタ本体２の長手方向に配列された複数の端子３，４とからなり、各端子３，４は配列方向に一つずつ交互に配置されている。
【００１３】
コネクタ本体２は合成樹脂の成形品からなり、その上面には基板挿入口２ａが設けられている。コネクタ本体２は各端子３，４が配置される複数の端子孔２ｂをコネクタ本体２の長手方向に間隔をおいて有し、各端子孔２ｂはコネクタ本体２の前端側及び後端側にそれぞれ設けられている。前端側及び後端側の各端子孔２ｂはそれぞれ基板挿入口２ａに連通しており、各端子孔２ｂの下端側はコネクタ本体２の下面に開口している。また、コネクタ本体２の前面下部及び背面下部には各端子孔２ｂに連通する空間部としての開口部２ｃが設けられ、開口部２ｃはコネクタ本体２の下端から上下方向ほぼ中央まで延びるスリット状に形成されている。
【００１４】
各端子３，４はそれぞれ弾性変形可能な導電性の金属からなり、その上端側を下方に屈曲させることにより、一側方に突出する山形の接触部３ａ，４ａを形成している。各端子３（４）は、前端側及び後端側の端子孔２ｂに互いに接触部３ａ（４ａ）が対向するように配置され、各接触部３ａ（４ａ）を基板挿入口２ａ内に突出させている。この場合、一方の端子３は上下方向に長く、他方の端子３は短く形成され、各端子３，４は互いに接触部３ａ，４ａの上下方向の位置が異なるようになっている。即ち、各端子３，４の接触部３ａ，４ａは、互いに隣接する接触部３ａ，４ａ同士が基板挿入方向（Ｙ方向）に距離Ｈだけずれるように配置されている。また、各端子３，４の下端側には基板との接続部３ｂ，４ｂが設けられ、各接続部３ｂ，４ｂはコネクタ本体２の前方（後方）に延出するように形成されている。
【００１５】
前記コネクタ１は、例えばパーソナルコンピュータの回路基板としての一対の基板５，６同士を接続するために用いられる。即ち、コネクタ１は、図３に示すように一方の基板５の下面に下向きに取付けられ、他方の基板６を下方から挿入することにより、各基板５，６同士を接続するようになっている。
【００１６】
この場合、他方の基板６の一端側にはコネクタ１に挿入される接続部６ａが突設され、接続部６ａの両面には多数の導電部６ｂが設けられている。各導電部６ｂは、基板６に印刷された所定の導電パターン（図示せず）に導通しており、コネクタ１の各端子３，４にそれぞれ対応するように、互いに隣接する導電部６ｂ同士がコネクタ１への挿入方向（Ｙ方向）に距離Ｈだけずれるように計２列に配置されている。即ち、各列の導電部６ｂ間の距離Ｈは、各端子３，４の接触部３ａ，４ａ間の距離Ｈに等しい。また、各導電部６ｂは、図６に示すようにコネクタ１の端子配列方向（Ｘ方向）に延びるように形成されるとともに、互いに隣接する導電部６ｂ同士が互いの一部をコネクタ１への挿入方向に距離Ｌ１ だけ間隔をおいて端子配列方向に長さＬ２ だけ重なり合うように設けられている。
【００１７】
以上の構成において、一方の基板５に取付けられコネクタ１に他方の基板６を接続する場合、基板６の接続部６ａをコネクタ１の基板挿入口２ａに挿入すると、互いに対向する各端子３，４の接触部３ａ，４ａ間に基板６の接続部６ａが介入し、各接触部３ａ，４ａが基板６の各導電部６ｂに圧接する。
【００１８】
ここで、基板挿入時等に基板６とコネクタ１とが端子配列方向（Ｘ方向）に位置ずれを生じた場合、端子３（４）の接触部３ａ（４ａ）と導電部６ｂとの位置ずれは、導電部６ｂの端子配列方向の長さＡだけ許容される。この場合、基板６では互いに隣接する導電部６ｂ同士がコネクタ１への挿入方向（Ｙ方向）に距離Ｈだけずれるように配置されているため、各導電部６ｂの長さＡを大きくすることができ、基板６とコネクタ１との位置ずれを生じても、隣接する導電部６ｂ同士の短絡や接触不良を生ずることがない。この場合、コネクタ１への基板挿入方向への位置ずれは、各導電部６ｂの基板挿入方向の長さＢだけ許容される。
【００１９】
また、基板６とコネクタ１とが端子配列方向及び基板挿入方向に直交する方向（Ｚ方向）に位置ずれを生じた場合には、図８に示すように各端子３，４の下端側がＺ方向に弾性変形し、基板６のＺ方向への位置ずれが吸収される。その際、各端子３，４の下端側の変位は、コネクタ本体２の開口部２ｃによってコネクタ本体２と干渉することなく許容される。
【００２０】
このように、本実施形態によれば、コネクタ１の各端子３，４の接触部３ａ，４ａを互いに隣接する接触部３ａ，４ａ同士が基板６の挿入方向に所定距離Ｈだけずれるように配置するとともに、基板６の各導電部６ｂを各端子３，４の接触部３ａ，４ａにそれぞれ対応するように互いに隣接する導電部６ｂ同士がコネクタ１への挿入方向に所定距離Ｈだけずれるように配置したので、各端子３，４を高密度に配置した場合でも、端子配列方向への基板６の位置ずれに対する許容範囲を十分に確保することができる。従って、基板６とコネクタ１との位置ずれによる導電部６ｂ同士の短絡や接触不良を確実に防止することができ、接続信頼性の向上を図ることができる。
【００２１】
この場合、各導電部６ｂをコネクタ１の端子配列方向に延びるように形成するとともに、互いに隣接する導電部６ｂ同士を互いの一部がコネクタ１への挿入方向に距離Ｌだけ間隔をおいてコネクタ１の端子配列方向に重なり合うように設けたので、各導電部６ｂを端子配列方向に長く形成することができ、基板６とコネクタ１との位置ずれに対する接続信頼性をより一層向上させることができる。
【００２２】
また、コネクタ１の各端子３，４を端子配列方向及び基板挿入方向に直交する方向に弾性変形可能に形成したので、同方向への位置ずれを各端子３，４の弾性変形によって吸収することができ、基板６との相対位置の誤差を解消することができる。
【００２３】
この場合、コネクタ本体２に各端子３，４のＺ方向への弾性変形を許容する開口部２ｃを設けたので、開口部２ｃによって各端子３，４をコネクタ本体２と干渉することなく弾性変形させることができ、コネクタ１と基板６との位置ずれが大きい場合でも、位置ずれを確実に吸収することができる。
【００２４】
尚、前記実施形態では、コネクタ本体２に設けた開口部２ｃによって空間部を形成するようにしたものを示したが、各端子３，４の弾性変形を許容可能であれば、コネクタ本体２に溝や隙間を設けることによって空間部を形成するようにしてもよい。
【００２５】
【発明の効果】
以上説明したように、請求項１の基板接続用コネクタによれば、端子を高密度に配置した場合でも、端子配列方向への基板の位置ずれに対する許容範囲を十分に確保することができるので、基板との位置ずれによる導電部同士の短絡や接触不良を確実に防止することができ、接続信頼性の向上を図ることができる。
【００２６】
また、請求項２の基板接続用コネクタによれば、請求項１の効果に加え、端子配列方向及び基板挿入方向に直交する方向への基板の位置ずれを吸収することができるので、同方向への基板との相対位置の誤差を解消することができる。
【００２７】
また、請求項３の基板接続用コネクタによれば、請求項２の効果に加え、各端子をコネクタ本体と干渉することなく弾性変形させることができるので、基板との位置ずれが大きい場合でも、位置ずれを確実に吸収することができる。
【００２８】
また、請求項４のコネクタ接続用基板によれば、請求項１、２または３記載の基板接続用コネクタと接続することにより、端子が高密度に配置されている場合でも、コネクタの端子配列方向への位置ずれに対する許容範囲を十分に確保することができるので、基板との位置ずれによる導電部同士の短絡や接触不良を確実に防止することができ、接続信頼性の向上を図ることができる。
【００２９】
また、請求項５のコネクタ接続用基板によれば、請求項４の効果に加え、各導電部を端子配列方向に長く形成することができるので、コネクタとの位置ずれに対する接続信頼性をより一層向上させることができる。

[Problems to be solved by the invention]
By the way, in the conventional example, since the conductive portions of the substrate are arranged in a line in the terminal arrangement direction of the connector, in connection with a connector in which a large number of terminals are arranged at high density, the terminal arrangement direction of each conductive portion is high.

The conductive parts adjacent to each other are arranged so as to be shifted by a predetermined distance in the direction of insertion into the connector so as to correspond to the contact parts, respectively. The conductive parts adjacent to each other are shifted from each other in the direction of insertion into the connector, so that the length of each conductive part of the substrate in the terminal arrangement direction can be increased. By connecting to the board connection connector, it is possible to sufficiently secure an allowable range for displacement of the board in the terminal arrangement direction.
[0010]

[0017]
In the above configuration, when the other board 6 is connected to the connector 1 which is attached to one board 5, when the connecting portion 6 a of the board 6 is inserted into the board insertion opening 2 a of the connector 1, the terminals 3, 4 facing each other are connected. The connecting portion 6a of the substrate 6 intervenes between the contact portions 3a and 4a, and the contact portions 3a and 4a are pressed against the conductive portions 6b of the substrate 6.
[0018]
Here, when the board 6 and the connector 1 are displaced in the terminal arrangement direction (X direction) when the board is inserted or the like, the displacement between the contact portion 3a (4a) of the terminal 3 (4) and the conductive portion 6b. Is allowed by the length A of the conductive portion 6b in the terminal arrangement direction. In this case, since the conductive portions 6b adjacent to each other on the substrate 6 are arranged so as to be shifted by the distance H in the insertion direction (Y direction) into the connector 1, the length A of each conductive portion 6b may be increased. As a result, even if the displacement between the substrate 6 and the connector 1 occurs, there is no short circuit or poor contact between the adjacent conductive portions 6b. In this case, the displacement of the connector 1 in the board insertion direction is allowed by the length B of each conductive portion 6b in the board insertion direction.
[0019]
When the board 6 and the connector 1 are displaced in a direction (Z direction) orthogonal to the terminal arrangement direction and the board insertion direction, the lower ends of the terminals 3 and 4 are moved in the Z direction as shown in FIG. The substrate 6 is elastically deformed, and the displacement of the substrate 6 in the Z direction is absorbed. At this time, displacement of the lower ends of the terminals 3 and 4 is allowed by the opening 2c of the connector main body 2 without interfering with the connector main body 2.
[0020]
As described above, according to the present embodiment, the contact portions 3a and 4a of the terminals 3 and 4 of the connector 1 are arranged such that the contact portions 3a and 4a adjacent to each other are shifted by the predetermined distance H in the insertion direction of the substrate 6. At the same time, the conductive portions 6b of the substrate 6 are shifted by a predetermined distance H in the direction of insertion into the connector 1 so that the adjacent conductive portions 6b correspond to the contact portions 3a, 4a of the terminals 3, 4, respectively. Since the terminals are arranged, even when the terminals 3 and 4 are arranged at a high density, an allowable range for the displacement of the substrate 6 in the terminal arrangement direction can be sufficiently ensured. Therefore, a short circuit or poor contact between the conductive portions 6b due to a displacement between the substrate 6 and the connector 1 can be reliably prevented, and connection reliability can be improved.
[0021]
In this case, each conductive portion 6b is formed so as to extend in the terminal arrangement direction of the connector 1, and the adjacent conductive portions 6b are separated from each other by a distance L in a direction in which a part of each of the conductive portions 6b is inserted into the connector 1. 1, the conductive portions 6b can be formed to be long in the terminal arrangement direction, and the connection reliability with respect to displacement between the board 6 and the connector 1 can be further improved. .
[0022]
In addition, since the terminals 3 and 4 of the connector 1 are formed so as to be elastically deformable in a direction orthogonal to the terminal arrangement direction and the board insertion direction, the displacement in the same direction is absorbed by the elastic deformation of the terminals 3 and 4. Thus, the error of the relative position with respect to the substrate 6 can be eliminated.
[0023]
In this case, since the connector body 2 is provided with the opening 2c that allows the terminals 3 and 4 to elastically deform in the Z direction, the terminals 3 and 4 are elastically deformed without interference with the connector body 2 by the opening 2c. Therefore, even when the positional deviation between the connector 1 and the substrate 6 is large, the positional deviation can be reliably absorbed.
[0024]
In the above embodiment, the space is formed by the opening 2c provided in the connector main body 2. However, if the elastic deformation of each of the terminals 3 and 4 can be permitted, the connector main body 2 may be formed. The space may be formed by providing a groove or a gap.
[0025]

[0026]
Further, according to the board connecting connector of the second aspect, in addition to the effect of the first aspect, the displacement of the board in the direction perpendicular to the terminal arrangement direction and the board insertion direction can be absorbed, so that the board can be moved in the same direction. The error of the relative position with respect to the substrate can be eliminated.
[0027]
According to the third aspect of the present invention, in addition to the effect of the second aspect, each terminal can be elastically deformed without interfering with the connector main body. The displacement can be reliably absorbed.
[0028]
