For example, the capacitance adjusting member 14 having only a mechanism for maintaining the distance between the connecting portions 12 and 13 (for example, a frame) may be used. It is also possible to form an air layer between the connecting portions 12 and 13.

接続構造１を組み立てる際には、第１グランド端子３の先端を第２グランド端子６のグランド側収容溝１５に収容してグランド側接続部１２を形成すると共に、第１給電端子４の先端を第２給電端子７の給電側収容溝１６に収容して給電側接続部１３を形成し、両接続部１２，１３間に静電容量調整部材１４を配置して、固定機構により両接続部１２，１３を静電容量調整部材１４に押しつけて固定する。この際、図１（ａ）の破線で囲んだ部分に示されるように、第１グランド端子３の先端面をグランド側収容溝１５の底面に、第１給電端子４の先端面を給電側収容溝１６の底面にしっかりと接触させた状態で、両接続部１２，１３を固定することが望ましい。 When assembling the connection structure 1, the tip of the first ground terminal 3 is accommodated in the ground-side accommodation groove 15 of the second ground terminal 6 to form the ground-side connection portion 12, and the tip of the first power supply terminal 4 is The power supply side receiving groove 13 of the second power supply terminal 7 is accommodated to form the power supply side connection portion 13, the capacitance adjusting member 14 is disposed between the both connection portions 12, 13, and the both connection portions 12 are fixed by a fixing mechanism. , 13 are pressed against the capacitance adjusting member 14 and fixed.

It is desirable to fix both connection parts 12 and 13 in a state where they are firmly in contact with the bottom surface of the groove 16.
ここで、接続部１２，１３におけるインピーダンスの調整方法について説明しておく。 Here, the adjustment method of the impedance in the connection parts 12 and 13 is demonstrated.
本実施の形態に係る接続構造１では、両接続部１２，１３間の静電容量を調整することにより、接続部１２，１３におけるインピーダンスを調整して、接続部１２，１３におけるインピーダンス不整合を低減させる。 In the connection structure 1 according to the present embodiment, the impedance at the connection parts 12 and 13 is adjusted by adjusting the capacitance between the connection parts 12 and 13, so that the impedance mismatch at the connection parts 12 and 13 is reduced. Reduce.
静電容量Ｃは、静電容量調整部材１４（ここでは誘電体）の比誘電率をε、接続部１２，１３間の距離（第１グランド端子３と第１給電端子４間の距離、または第２グランド端子６と第２給電端子７間の距離）をＬ、両接続部１２，１３の対向部分の断面積をＡとすると、下式（１）
Ｃ＝ε・ε0（Ａ／Ｌ） ・・・（１）
但し、ε0：真空の誘電率（８．８５×１０-12Ｆ／ｍ）
で表される。
The capacitance C is the dielectric constant of the capacitance adjusting member 14 (here, a dielectric) ε, the distance between the connecting portions 12 and 13 (the distance between the first ground terminal 3 and the first power supply terminal 4, or When the distance between the second ground terminal 6 and the second power supply terminal 7 is L, and the cross-sectional area of the facing portions of the connecting portions 12 and 13 is A, the following formula (1)
C = ε · ε 0 (A / L) (1)
However, ε 0 : Dielectric constant of vacuum (8.85 × 10 −12 F / m)
It is represented by
よって、静電容量調整部材１４として用いる誘電体の比誘電率ε、接続部１２，１３間の距離Ｌ、両接続部１２，１３の対向部分の断面積Ａのうち１つまたは複数を調整することにより、両接続部１２，１３間の静電容量Ｃを適切な値に調整することが可能になる。 Therefore, one or more of the relative dielectric constant ε of the dielectric used as the capacitance adjusting member 14, the distance L between the connecting portions 12 and 13, and the cross-sectional area A of the opposing portions of the connecting portions 12 and 13 are adjusted. This makes it possible to adjust the capacitance C between the connection portions 12 and 13 to an appropriate value.
本実施の形態では、各端子３，４，６，７を保持する構造を別途備えない場合について説明したが、これに限らず、第１端子部２に第１グランド端子３と第１給電端子４を整列保持する機構を設けたり、第２端子部５に第２グランド端子６と第２給電端子７を整列保持する機構を設けてもよく、さらに両端子部２，５を覆うようにハウジング等を設けて、コネクタタイプとしてもよい。 In the present embodiment, a case where a structure for holding the terminals 3, 4, 6, and 7 is not separately provided has been described. However, the present invention is not limited to this, and the first terminal portion 2 includes the first ground terminal 3 and the first power supply terminal. 4 may be provided, or the second terminal portion 5 may be provided with a mechanism for aligning and holding the second ground terminal 6 and the second power supply terminal 7, and the housing may be further covered with the terminal portions 2 and 5. Etc. may be provided as a connector type.
この場合、第１端子部２を、第１グランド端子３と第１給電端子４間の距離を可変に構成すると共に、第２端子部５を、第２グランド端子６と第２給電端子７間の距離を可変に構成することが望ましい。これにより、接続部１２，１３間に設ける静電容量調整部材１４の材質や大きさ（つまり、上述の式（１）におけるεとＬ）を調整すれば、両接続部１２，１３間の静電容量Ｃを容易に変更することが可能となり、汎用性を高めることができる。 In this case, the first terminal portion 2 is configured such that the distance between the first ground terminal 3 and the first power feeding terminal 4 is variable, and the second terminal portion 5 is disposed between the second ground terminal 6 and the second power feeding terminal 7. It is desirable to make the distance of the variable. As a result, if the material and size of the capacitance adjusting member 14 provided between the connecting portions 12 and 13 (that is, ε and L in the above equation (1)) are adjusted, the static between the connecting portions 12 and 13 is adjusted. The capacitance C can be easily changed, and versatility can be improved.
以上説明したように、本実施の形態に係る接続構造１では、第１グランド端子３と第２グランド端子６とを接続するグランド側接続部１２と、第１給電端子４と第２給電端子７とを接続する給電側接続部１３とを、当該両接続部１２，１３間の静電容量Ｃを調整するための静電容量調整部材１４を介して対向配置している。 As described above, in the connection structure 1 according to the present embodiment, the ground-side connection portion 12 that connects the first ground terminal 3 and the second ground terminal 6, the first feeding terminal 4, and the second feeding terminal 7. Are connected to each other via a capacitance adjusting member 14 for adjusting the capacitance C between the connecting portions 12 and 13.
このように構成することで、静電容量調整部材１４として用いる誘電体の比誘電率ε、接続部１２，１３間の距離Ｌ、両接続部１２，１３の対向部分の断面積Ａのうち１つまたは複数を調整することにより、両接続部１２，１３間の静電容量Ｃを適切な値に調整し、接続部１２，１３におけるインピーダンス不整合を低減させることが可能になる。 With this configuration, one of the relative dielectric constant ε of the dielectric used as the capacitance adjusting member 14, the distance L between the connecting portions 12 and 13, and the cross-sectional area A of the facing portions of the connecting portions 12 and 13 is 1 By adjusting one or more, it is possible to adjust the capacitance C between the connection portions 12 and 13 to an appropriate value and reduce impedance mismatch at the connection portions 12 and 13.
接続構造１は、接続部１２，１３での伝送損失を低減できるため、大電流を用いる非接触用給電装置等の高周波コネクタに用いる接続構造として好適である。 Since the connection structure 1 can reduce transmission loss in the connection parts 12 and 13, it is suitable as a connection structure used for a high-frequency connector such as a non-contact power supply device using a large current.
また、接続構造１では、第１グランド端子３、第１給電端子４、第２グランド端子６、および第２給電端子７を平板状に形成しているため、静電容量Ｃの計算が容易となり、設計を容易とすることができる。なお、静電容量Ｃの計算は若干複雑になるが、各端子３，４，６，７を平板状でない形状、例えば断面形状が楕円形状となるように形成することも、当然に可能である。 Moreover, in the connection structure 1, since the 1st ground terminal 3, the 1st electric power feeding terminal 4, the 2nd ground terminal 6, and the 2nd electric power feeding terminal 7 are formed in flat form, the calculation of the electrostatic capacitance C becomes easy. Design can be made easy. Although the calculation of the capacitance C is slightly complicated, it is of course possible to form the terminals 3, 4, 6 and 7 so that they are not flat, for example, the cross-sectional shape is elliptical. .
次に、本発明の他の実施の形態を説明する。 Next, another embodiment of the present invention will be described.
図３（ａ），（ｂ）に示す接続構造３１は、図１の接続構造１において、グランド側収容溝１５を第２グランド端子６の先端面の中央部に形成すると共に、給電側収容溝１６を第２グランド端子６の先端面の中央部に形成し、第２グランド端子６と第２給電端子７を断面視で反時計周りに９０度回転した凹字状に形成したものである。 The connection structure 31 shown in FIGS. 3A and 3B is the same as the connection structure 1 shown in FIG. 1 except that the ground side accommodation groove 15 is formed at the center of the distal end surface of the second ground terminal 6 and the power supply side accommodation groove. 16 is formed at the center of the front end surface of the second ground terminal 6, and the second ground terminal 6 and the second power supply terminal 7 are formed in a concave shape rotated 90 degrees counterclockwise in a cross-sectional view.
接続構造３１では、第１グランド端子３と第２グランド端子６の間と、第１給電端子４と第２給電端子７の間に段差ができるので、静電容量調整部材１４を断面視で反時計周りに９０度回転したＴ字状に形成し、段差によってできた空間を埋めるようにしている。 In the connection structure 31, there is a step between the first ground terminal 3 and the second ground terminal 6 and between the first power supply terminal 4 and the second power supply terminal 7, so that the capacitance adjusting member 14 is shown in a cross-sectional view. It is formed in a T-shape rotated 90 degrees clockwise to fill the space created by the steps.
本実施の形態では、第１端子部２の端子３，４が接触する部分の静電容量調整部材１４を、段差によってできた空間よりも若干低く形成し、第１端子部２の端子３，４にバネ力（押さえつける力）を作用させることで、両接続部１２，１３を静電容量調整部材１４にしっかりと固定するようになっている。なお、第１端子部２の端子３，４が接触する部分の静電容量調整部材１４を、段差によってできた空間よりも若干高く形成し、第２端子部５の端子６，７にバネ力（押さえつける力）を作用させることで、両接続部１２，１３を静電容量調整部材１４に固定するよう構成することも可能である。 In the present embodiment, the capacitance adjusting member 14 at the portion where the terminals 3 and 4 of the first terminal portion 2 are in contact is formed slightly lower than the space formed by the step, and the terminals 3 and 3 of the first terminal portion 2 are formed. By applying a spring force (pressing force) to 4, both connecting portions 12 and 13 are firmly fixed to the capacitance adjusting member 14. In addition, the capacitance adjusting member 14 in the portion where the terminals 3 and 4 of the first terminal portion 2 are in contact with each other is formed slightly higher than the space formed by the step, and the spring force is applied to the terminals 6 and 7 of the second terminal portion 5. It is also possible to configure so that both the connecting portions 12 and 13 are fixed to the capacitance adjusting member 14 by applying (pressing force).
また、図４に示す接続構造４１のように、静電容量調整部材１４を直方体状のままとし、段差によってできた空間を埋めないように構成することも当然に可能である。ただし、接続構造４１では、第１端子部２の端子３，４に強いバネ力（押さえつける力）を作用させると、端子３，４の先端部に変形が生じてしまうおそれがあるため、両グランド端子３，６、両給電端子４，７を接続した状態で保持する機構を別途設けることが望ましい。 Further, as in the connection structure 41 shown in FIG. 4, it is naturally possible to configure the capacitance adjusting member 14 to be a rectangular parallelepiped shape so as not to fill the space formed by the steps. However, in the connection structure 41, if a strong spring force (pressing force) is applied to the terminals 3 and 4 of the first terminal portion 2, there is a risk that the tip portions of the terminals 3 and 4 may be deformed. It is desirable to separately provide a mechanism for holding the terminals 3 and 6 and the power feeding terminals 4 and 7 in a connected state.
なお、図３，４に示した接続構造３１，４１では、段差の前後で領域を分けて静電容量Ｃを計算する必要がある。図３の接続構造３１では、第１給電端子４と第１グランド端子３間に空気層が介在しないため、図４の接続構造４１よりも静電容量Ｃの計算が容易である。 In the connection structures 31 and 41 shown in FIGS. 3 and 4, it is necessary to calculate the capacitance C by dividing the region before and after the step. In the connection structure 31 in FIG. 3, since the air layer is not interposed between the first power supply terminal 4 and the first ground terminal 3, the capacitance C can be calculated more easily than the connection structure 41 in FIG. 4.
本発明は上記実施の形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々の変更を加え得ることは勿論である。 The present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the spirit of the present invention.
