しかしながら、回路基板用コネクタを構成する前記内部端子は、回路基板上のプリントパターンへの半田付けに関し、内部端子と回路基板との電気的接続およびその接続強度を十分に確保することができない場合がある。この点を図6を参照して説明すると、内部端子1は製造過程においてキャリア2から切り離されるが、その内部端子1とキャリアとの切断位置であるキャリア接続切断位置3を回路基板接続部4とキャリア2との間に設定した場合、このようなキャリア接続切断位置3で該キャリア2を切断する、回路基板接続部4の端面5は切断面となることから、この切断面にはめっきがない状態になってしまう。   However, the internal terminals constituting the circuit board connector may not be able to ensure sufficient electrical connection and connection strength between the internal terminals and the circuit board in connection with soldering to the printed pattern on the circuit board. is there. This point will be described with reference to FIG. 6. The internal terminal 1 is separated from the carrier 2 in the manufacturing process, but the carrier connection cutting position 3, which is a cutting position between the internal terminal 1 and the carrier, is connected to the circuit board connecting portion 4. When set between the carrier 2 and the carrier connection cutting position 3, the carrier 2 is cut, and the end surface 5 of the circuit board connecting portion 4 is a cut surface. It becomes a state.

従って、回路基板上で回路基板接続部4の端面5の位置にフィレットの半田を載せようとしても思うように載らず、図7に示すように、裾広がり形状となるフィレット7の形成ができなくなってしまう。この結果、回路基板接続部4と回路基板上のプリントパターンとの電気的接続および接続強度を十分に確保することが困難になり、コネクタの基板に対する接続の信頼性が低下するという問題点があった。   Accordingly, it is not possible to place the fillet solder on the circuit board at the position of the end surface 5 of the circuit board connecting portion 4 as expected, and as shown in FIG. 7, the fillet 7 having a flared shape cannot be formed. End up. As a result, it is difficult to ensure sufficient electrical connection and connection strength between the circuit board connecting portion 4 and the printed pattern on the circuit board, and there is a problem that the reliability of connection of the connector to the board is lowered. It was.

また、この問題点を解決するために、キャリア接続切断位置を、図8に示すように内部端子1における連結部8の位置に設定すると、この場合は回路基板接続部4にめっきが有ることからフィレット7が形成されて、電気的接続を十分に確保することができるようになる。しかしながら、キャリア接続切断位置3で切断を行うような工程では、切断の際の外力が半田付け部分に加わり、回路基板接続部4に歪を生じてしまう惧れがある。   In order to solve this problem, when the carrier connection cutting position is set to the position of the connecting portion 8 in the internal terminal 1 as shown in FIG. 8, in this case, the circuit board connecting portion 4 has plating. Fillet 7 is formed, and sufficient electrical connection can be secured. However, in the process of cutting at the carrier connection cutting position 3, an external force at the time of cutting may be applied to the soldered portion, and the circuit board connecting portion 4 may be distorted.

更に、図9に示すように、電気接触部9とキャリア2との間にキャリア接続切断位置3を設定する場合に合っては、切断面にバリが残ったままであると、相手側内部端子との接続の際にこのバリが引っ掛かってしまったり、相手側内部端子に傷を付けるという不都合があった。   Furthermore, as shown in FIG. 9, when the carrier connection cutting position 3 is set between the electric contact portion 9 and the carrier 2, if the burr remains on the cut surface, There was a problem that this burr was caught during the connection, and the counterpart internal terminal was scratched.

本発明は、上述した事情に鑑みてなされたものであり、その目的は、回路基板用コネクタの内部端子の回路基板に対する半田による電気的接続の信頼性を高めることができる回路基板用コネクタの内部端子提供することにある。 The present invention has been made in view of the above-described circumstances, and an object thereof is the inside of a circuit board connector that can improve the reliability of electrical connection of the internal terminals of the circuit board connector to the circuit board by soldering. To provide a terminal.

上記()の構成の回路基板用の内部端子によれば、キャリアとの分断面が従来のように電気接触部や回路基板接続部に作られないため、電気接続部が相手側端子の電気接触部にスムースに接続しなかったり、相手端子の電気接触部を損傷したり、回路基板接続部の前記プリントパターンに対する半田付けが不完全になったりすることはない。また、キャリアを分断する幅(分断する矩形片の面積)を調整することで、回路基板用コネクタ組付け状態において回路基板用コネクタと回路基板との接続部分で生じるインピーダンスの乱れを抑えることができる。これにより、同軸ケーブル側のインピーダンスとの整合を取ることができ、高周波特性の劣化を最小限に抑えることができる。
また、分断されたキャリアが内部端子として回路基板用コネクタ内の絶縁部材へ装着される際に、切欠がその絶縁部材内に強く係合される。従って、その絶縁部材に対し内部端子を脱抜不可能に硬く保持することができ、内部端子の取り付け状態を安定化することができる。
上記()の構成の回路基板用の内部端子によれば、前記矩形片の一部である打出し片が外部端子に近接して対面するため、この打出し片と外部端子との間の対地静電容量が増大する。この打出し片の形成することによって、矩形片のサイズを大型化することなく、高い値の対地静電容量を設定できる。従って、一般に回路基板用コネクタの内部端子と回路基板との接続部分で低くなるインピーダンスを、打出し片による静電容量の増加によって高インピーダンスに導くことができる。
上記()の構成の回路基板用の内部端子によれば、打出し片と外部端子との間の対地静電容量をより増大させることができる。
According to the internal terminal for a circuit board having the configuration of ( 1 ) above, since the divided section with the carrier is not formed in the electrical contact part or the circuit board connection part as in the prior art, the electrical connection part is the electrical terminal of the counterpart terminal. There is no smooth connection to the contact portion, no damage to the electrical contact portion of the mating terminal, or incomplete soldering of the circuit board connection portion to the printed pattern. Further, by adjusting the width for dividing the carrier (the area of the rectangular piece to be divided), it is possible to suppress the disturbance of impedance that occurs at the connection portion between the circuit board connector and the circuit board in the assembled state of the circuit board connector. . Thereby, matching with the impedance on the coaxial cable side can be achieved, and deterioration of the high frequency characteristics can be minimized.
Further , when the divided carrier is attached as an internal terminal to the insulating member in the circuit board connector, the notch is strongly engaged in the insulating member. Therefore, the internal terminal can be firmly held against the insulating member so as not to be removed, and the mounting state of the internal terminal can be stabilized.
According to the internal terminal for a circuit board having the configuration of ( 2 ) above, since the projecting piece which is a part of the rectangular piece faces in close proximity to the external terminal, there is a gap between the projecting piece and the external terminal. The ground capacitance increases. By forming this projecting piece, a high value of the ground capacitance can be set without increasing the size of the rectangular piece. Therefore, the impedance which is generally lowered at the connection portion between the internal terminal of the circuit board connector and the circuit board can be led to a high impedance by increasing the electrostatic capacitance due to the projecting piece.
According to the internal terminal for a circuit board having the configuration ( 3 ), the ground capacitance between the projecting piece and the external terminal can be further increased.

本発明によれば、回路基板用コネクタの内部端子の回路基板に対する半田による電気的接続および接続強度の信頼性を高めることができ、キャリアの切断時に半田付け部に歪が発生するのを防止できるとともに、回路基板用コネクタと回路基板との接続部分で生じるインピーダンスの乱れを抑えて、高周波性能の劣化を回避することができる。   ADVANTAGE OF THE INVENTION According to this invention, the reliability of the electrical connection and the connection intensity | strength by solder with respect to the circuit board of the internal terminal of the connector for circuit boards can be improved, and it can prevent generating a distortion in a soldering part at the time of a cutting | disconnection of a carrier. At the same time, it is possible to suppress the disturbance of the impedance generated at the connection portion between the circuit board connector and the circuit board, and to avoid the deterioration of the high frequency performance.

以下、本発明の一実施の形態にかかる回路基板用コネクタの内部端子を、図面を参照して説明する。図1は、本発明に係る実施形態の回路基板用コネクタの内部端子を示す斜視図を示す。符号21は本発明における内部端子を示している。内部端子21は、回路基板22上に設けられる回路基板用コネクタ(同軸コネクタ)23を構成する一部品であって、後述する連鎖端子41を分断することによって形成される。   Hereinafter, internal terminals of a circuit board connector according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing internal terminals of a circuit board connector according to an embodiment of the present invention. Reference numeral 21 denotes an internal terminal in the present invention. The internal terminal 21 is a component constituting a circuit board connector (coaxial connector) 23 provided on the circuit board 22 and is formed by dividing a chain terminal 41 described later.

まず、内部端子21の構成について説明する。内部端子21は、電気接触部25と、回路基板接続部26と、これらを連結する連結部27と、を有している。電気接触部25は、回路基板用同軸コネクタ23との接続相手となる相手側同軸コネクタ(図示省略)の相手側内部端子と接触する部分であって、拡径可能な弾性を有する筒状に形成されている(相手側内部端子はピン状の雄型形状になっている)。   First, the configuration of the internal terminal 21 will be described. The internal terminal 21 has an electrical contact portion 25, a circuit board connection portion 26, and a connection portion 27 that connects them. The electrical contact portion 25 is a portion that contacts a counterpart internal terminal of a counterpart coaxial connector (not shown) that is a counterpart to the circuit board coaxial connector 23, and is formed in a cylindrical shape having elasticity capable of expanding the diameter. (The other-side internal terminal has a pin-shaped male shape).

回路基板接続部26は、細長い板状をなしており、回路基板22のプリントパターン28に半田付けされる部分として形成されている。回路基板接続部26は、表裏が平坦となるように形成されている。   The circuit board connecting portion 26 has an elongated plate shape and is formed as a portion to be soldered to the printed pattern 28 of the circuit board 22. The circuit board connecting portion 26 is formed so that the front and back sides are flat.

連結部27は、上記のように電気接触部25と回路基板接続部26とを連結する部分であり、一端が電気接触部25に、他端が回路基板接続部26に連設されている。連結部27は電気接触部25の軸に沿って延び、回路基板22に平行となる水平方向部分29と、この水平方向部分29および回路基板接続部26に直交するように延びる垂直方向部分30と、水平方向部分29の途中に(一部に)延設された面積の広い矩形片31と、を有し、略L字状に折り曲げ形成されている。   The connecting portion 27 is a portion that connects the electrical contact portion 25 and the circuit board connection portion 26 as described above, and has one end connected to the electrical contact portion 25 and the other end connected to the circuit board connection portion 26. The connecting portion 27 extends along the axis of the electrical contact portion 25 and is parallel to the circuit board 22, and the vertical portion 30 extends perpendicular to the horizontal portion 29 and the circuit board connecting portion 26. The rectangular piece 31 having a large area extending in the middle (partly) of the horizontal portion 29 is bent into a substantially L shape.

矩形片31は、後述のキャリア41を長手方向の所定の間隔ごとに切断し、該キャリア41を分断して形成されたものの一つであり、水平方向部分29の左右両端部から突出するような形状に形成されている。従って、この矩形片31の幅Wは、水平方向部分29の幅Lに比べて十分に長めの寸法となっている。また、矩形片31は水平方向部分29と同じ肉厚で表裏とも水平方向部分29に同一平面となる板状に形成されている。   The rectangular piece 31 is one formed by cutting a carrier 41, which will be described later, at predetermined intervals in the longitudinal direction and dividing the carrier 41, and protrudes from the left and right ends of the horizontal portion 29. It is formed into a shape. Therefore, the width W of the rectangular piece 31 is sufficiently longer than the width L of the horizontal portion 29. The rectangular piece 31 has the same thickness as the horizontal portion 29 and is formed in a plate shape that is flush with the horizontal portion 29 on both sides.

なお、この矩形片31の幅Wは、後述する連鎖端子のキャリア切断時に適宜設定可能である。この矩形片31の幅は、回路基板用コネクタ23と回路基板22との接続部分、詳しくは回路基板用コネクタ23に取り付けられる内部端子21と回路基板22のプリントパターン28との接続部におけるインピーダンスの乱れ(不揃い)を解消とするために最適長さに設定できる。例えば、インピーダンスを上げたい場合には矩形片31の幅Wを短くして該矩形片31の面積を小さくし、インピーダンスを下げたい場合には矩形片31の幅Wを長くして該矩形片31の面積を大きくするようなサイズに切断すればよい。好適には、所望の高周波特性が得られるように、シミュレーションや試作品を用いて矩形片31の面積を決定する。   Note that the width W of the rectangular piece 31 can be set as appropriate at the time of carrier cutting of a chain terminal described later. The width of the rectangular piece 31 is the impedance of the connection portion between the circuit board connector 23 and the circuit board 22, specifically the connection portion between the internal terminal 21 attached to the circuit board connector 23 and the printed pattern 28 of the circuit board 22. It can be set to an optimum length to eliminate disturbances (unevenness). For example, when the impedance is desired to be increased, the width W of the rectangular piece 31 is shortened to reduce the area of the rectangular piece 31, and when the impedance is desired to be lowered, the rectangular piece 31 is increased in width W. What is necessary is just to cut | disconnect to the size which enlarges the area of. Preferably, the area of the rectangular piece 31 is determined using simulation or a prototype so that a desired high-frequency characteristic can be obtained.

また、キャリアを分断して形成された矩形片31の2つの分断面には、抜け止め用の円弧状の切欠32が形成されている(切欠32の形成するための処理については、図2を参照して後述する。)。この切欠32は、内部端子21を回路基板用コネクタ23内の絶縁部材に固定する際に、その円弧状の切欠32が絶縁部材の内部に食い込むように嵌合される。このため、内部端子21がコネクタの絶縁部材内に脱抜されることなく確実かつ安定的に保持される。なお、このような安定的な脱抜防止効果は、前記円弧状切欠32に代えて各種形状の切欠や突部とすることによっても得られ、設計者の任意とするところである。   In addition, arc-shaped notches 32 for retaining are formed in two divided sections of the rectangular piece 31 formed by dividing the carrier (see FIG. 2 for the processing for forming the notches 32). It will be described later with reference.) The notch 32 is fitted so that the arc-shaped notch 32 bites into the insulating member when the internal terminal 21 is fixed to the insulating member in the circuit board connector 23. For this reason, the internal terminal 21 is reliably and stably held without being removed from the insulating member of the connector. Such a stable removal prevention effect can also be obtained by using various shapes of notches and protrusions instead of the arcuate notches 32, and is arbitrarily determined by the designer.

図2は、本発明に係る実施形態の回路基板用コネクタの連鎖端子を示す斜視図を示す。この連鎖端子40は、長尺の帯状金属板をプレスにより打ち抜いて形成された帯状のキャリア41と、このキャリア41の幅方向の一端側に連設された複数の電気接触部25と、キャリア41の幅方向の他端側に該キャリア41を挟んで電気接触部25と対向する位置に連設された複数の回路基板接続部26と、を有する。この連鎖端子40は、導電性を有する金属板をプレス加工し、その後めっき処理を施すことによって、図示の形状に形成されている。   FIG. 2: shows the perspective view which shows the chain terminal of the connector for circuit boards of embodiment which concerns on this invention. The chain terminal 40 includes a strip-shaped carrier 41 formed by punching a long strip-shaped metal plate by pressing, a plurality of electrical contact portions 25 continuously provided on one end side in the width direction of the carrier 41, and the carrier 41. And a plurality of circuit board connecting portions 26 connected in a position facing the electrical contact portion 25 with the carrier 41 interposed therebetween on the other end side in the width direction. The chain terminal 40 is formed in the shape shown in the figure by pressing a conductive metal plate and then performing a plating process.

そして、電気接触部25およびこれに対向する回路基板接続部26を結ぶ各直線(仮想線)Nの略中間位置には、キャリア41の上面から下面にかけて貫通する透孔33が形成されている。この透孔33は、これまでのキャリアにも、キャリアの曲げに対する強度を向上させるために、また、その透孔33の位置に基づいてキャリア41に連設された電気接触部25および回路基板接続部26の位置(つまり、内部端子21の位置)を特定することために設けられていたものであり、このため、本発明の実施形態においても、キャリア自体が変形したり撓んだりすることに対する耐性を向上させることができる。   A through hole 33 penetrating from the upper surface to the lower surface of the carrier 41 is formed at a substantially intermediate position between the straight lines (virtual lines) N connecting the electric contact portion 25 and the circuit board connecting portion 26 facing the electric contact portion 25. The through-hole 33 is used to improve the strength against bending of the carrier in the conventional carrier, and to connect the electric contact portion 25 and the circuit board connected to the carrier 41 based on the position of the through-hole 33. This is provided to specify the position of the portion 26 (that is, the position of the internal terminal 21). Therefore, even in the embodiment of the present invention, the carrier itself is deformed or bent. Resistance can be improved.

このようにして形成されるキャリア41が、長さ方向の所定の間隔W(前述の内部端子21の幅Wと一致。)で分断されることによって、図1に示すような内部端子21が得られる。図2に示すキャリア41の分断位置は、電気接触部25およびこれに対向する回路基板接続部26を結ぶ各直線(仮想線)N間の略中間位置であって、キャリア41の長手方向に直交する幅方向(図2に示すような分断面42上)である(このため、分断面42である内部端子21の矩形片31の両端部には、めっきが施されていない。)。なお、この分断位置では、透孔33を分割するようにキャリア41が切断されるため、図1に示すに、内部端子21の矩形片31が形成されると同時に、切欠32が矩形片31に形成される。   The carrier 41 formed in this manner is divided at a predetermined interval W in the length direction (matching the width W of the internal terminal 21 described above), whereby the internal terminal 21 as shown in FIG. 1 is obtained. It is done. The dividing position of the carrier 41 shown in FIG. 2 is a substantially intermediate position between each straight line (virtual line) N connecting the electrical contact portion 25 and the circuit board connecting portion 26 facing the electrical contact portion 25, and orthogonal to the longitudinal direction of the carrier 41. The width direction (on the dividing surface 42 as shown in FIG. 2) (for this reason, plating is not applied to both ends of the rectangular piece 31 of the internal terminal 21 which is the dividing surface 42). At this dividing position, since the carrier 41 is cut so as to divide the through hole 33, the rectangular piece 31 of the internal terminal 21 is formed at the same time as shown in FIG. It is formed.

このようにして分断されて得られる図1に示す内部端子21は、キャリア41から分断された後も、回路基板接続部26にはめっきが施された状態である。従って、回路基板接続部26の回路基板22上のプリントパターン28に対する好適な半田フィレットによる半田接続が可能になり、回路基板接続部26とプリントパターン28との電気接続が確実なものとなる。   The internal terminal 21 shown in FIG. 1 obtained by dividing in this way is in a state where the circuit board connecting portion 26 is plated even after being divided from the carrier 41. Therefore, solder connection by a suitable solder fillet to the printed pattern 28 on the circuit board 22 of the circuit board connecting portion 26 is possible, and the electrical connection between the circuit board connecting portion 26 and the printed pattern 28 is ensured.

また、キャリア41は分断後も内部端子21の一部として用いられるため、図3、図5、図6に示す従来の連鎖端子のように、内部端子を取り出した後に不要になったキャリアを廃棄することがなくなる。更に、キャリア41の分断による矩形部31の形状、つまり面積を適正化することによって、回路基板用コネクタ23と回路基板22との接続箇所におけるインピーダンスの乱れを回避し、更にケーブル側とのインピーダンスマッチングを取ることによって、高周波特性の劣化を最小限に抑えることができる。このため、本発明の実施形態では、内部端子21を製造するために発生し得る無駄を省くことができ、環境負荷の低減を図ることができるとともに、従来廃棄されるしかなかったキャリアをインピーダンスマッチングを図るための有用な構成として活用することができる。   Further, since the carrier 41 is used as a part of the internal terminal 21 even after being divided, the unnecessary carrier after the internal terminal is taken out is discarded as in the conventional chain terminal shown in FIGS. There is no longer to do. Further, by optimizing the shape of the rectangular portion 31 by dividing the carrier 41, that is, the area, impedance disturbance at the connection portion between the circuit board connector 23 and the circuit board 22 is avoided, and impedance matching with the cable side is further performed. By taking this, the deterioration of the high frequency characteristics can be minimized. For this reason, in the embodiment of the present invention, waste that may occur in order to manufacture the internal terminal 21 can be eliminated, the environmental load can be reduced, and the carrier that has been conventionally discarded can be impedance-matched. It can be utilized as a useful configuration for achieving the above.

なお、本発明の実施形態では、キャリア41の分断位置は、電気接触部25およびこれに対向する回路基板接続部26を結ぶ各直線(仮想線)N間の略中間位置としたが、これに限るものではない。キャリア41における、隣り合う電気接触部25および回路基板接続部26の間に位置する箇所を、切断しさえすればよい。このとき、その切断位置が透孔33を通過するようにしておけば、別途切欠32を形成する処理を追加することなく、簡易に切欠32を形成することができる。   In the embodiment of the present invention, the dividing position of the carrier 41 is a substantially intermediate position between each straight line (virtual line) N connecting the electric contact portion 25 and the circuit board connecting portion 26 facing the electric contact portion 25. It is not limited. What is necessary is just to cut | disconnect the location located in the carrier 41 between the adjacent electrical contact part 25 and the circuit board connection part 26. FIG. At this time, if the cutting position passes through the through-hole 33, the notch 32 can be easily formed without adding a separate process for forming the notch 32.

なお、本発明の実施形態では、電気接触部25およびこれに対向する回路基板接続部26を結ぶ各直線(仮想線)Nの略中間位置に透孔33を設けるようにしたが、電気接触部25およびこれに対向する回路基板接続部26を結ぶ各直線N上に透孔33を設けるようにしてもよい。この構成は、切欠32を形成するための処理を別途行う必要があるものの、本発明の効果、すなわち、内部端子21を製造するために発生し得る無駄を省くことができ、環境負荷の低減を図ることができるとともに、従来廃棄されるしかなかったキャリアをインピーダンスマッチングを図るための有用な構成として活用することを実現することができる。   In the embodiment of the present invention, the through hole 33 is provided at a substantially intermediate position between the straight lines (virtual lines) N connecting the electrical contact portion 25 and the circuit board connection portion 26 facing the electrical contact portion 25. 25 and a through hole 33 may be provided on each straight line N connecting the circuit board connecting portion 26 opposed to this. Although this configuration requires a separate process for forming the notch 32, the effect of the present invention, that is, waste that may occur in order to manufacture the internal terminal 21, can be eliminated, and the environmental load can be reduced. In addition to being able to achieve this, it is possible to realize utilization of a carrier that has conventionally been discarded as a useful configuration for impedance matching.

ところで、回路基板用コネクタ23は、図3の本発明に係る実施形態の回路基板用コネクタを示す縦断正面図に示すように、円筒中空状の外部端子50と、その外部端子50の内部に固定され、内部端子21によって貫通される取付孔52が形成された絶縁部材51と、外部端子50の外表面を覆うコネクタハウジング54と、を備えている。ここで、内部端子21によって絶縁部材51の取付孔52が貫通されている状態において、矩形片31の外部端子50に対する対地静電容量は、内部端子21の矩形片31の平面部分とこれを囲む外部端子50の内周面と外部端子50との間隔Hに反比例し、一方、これらの平面部と内周面との対向面積に比例する(C=ε0S/d、Cは静電容量、ε0は絶縁部材の誘電率、Sは対向面積、dは間隔)ことから、間隔Hが小さくなるほど内部端子21の対地静電容量が高くなって、インピーダンスが高い状態となり、また、対向面積Sが大きくなるほど内部端子21の対地静電容量が高くなって、インピーダンスが高い状態となる。 By the way, the circuit board connector 23 is fixed to a cylindrical hollow external terminal 50 and to the inside of the external terminal 50 as shown in a longitudinal front view of the circuit board connector according to the embodiment of the present invention shown in FIG. And an insulating member 51 in which a mounting hole 52 that is penetrated by the internal terminal 21 is formed, and a connector housing 54 that covers the outer surface of the external terminal 50. Here, in the state where the mounting hole 52 of the insulating member 51 is penetrated by the internal terminal 21, the ground capacitance with respect to the external terminal 50 of the rectangular piece 31 surrounds the planar portion of the rectangular piece 31 of the internal terminal 21 and this. It is inversely proportional to the distance H between the inner peripheral surface of the external terminal 50 and the external terminal 50, while it is proportional to the facing area between these flat portions and the inner peripheral surface (C = ε 0 S / d, C is the capacitance) , Ε 0 is the dielectric constant of the insulating member, S is the facing area, and d is the spacing). Therefore, the smaller the spacing H, the higher the ground capacitance of the internal terminal 21 and the higher the impedance, and the facing area. As S increases, the ground capacitance of the internal terminal 21 increases and the impedance becomes high.

このため、(対向面積Sが大きい)矩形片31を前述のように形成することによって、内部端子21とこの内部端子21を絶縁部材を介して覆う外部端子との間に発生する静電容量を、増加させることができる。この静電容量の増加により回路基板用コネクタ23のインピーダンスを局所的に高めて、内部端子21と回路基板22との接続部にて低下するインピーダンスの低下分を補い、平均化するように調整できる。この結果、前記接続部を含む伝送路全体の高周波特性を向上することができる。   For this reason, the electrostatic capacitance generated between the internal terminal 21 and the external terminal that covers the internal terminal 21 via the insulating member is formed by forming the rectangular piece 31 (having the large facing area S) as described above. Can be increased. The increase in capacitance can locally increase the impedance of the circuit board connector 23 to compensate for the decrease in impedance that decreases at the connection portion between the internal terminal 21 and the circuit board 22 and can be adjusted to be averaged. . As a result, it is possible to improve the high frequency characteristics of the entire transmission line including the connection portion.

ところが、幅広の矩形片31を形成することによって、この矩形片31を持つ内部端子21の大型化、ひいては回路基板用コネクタ23の大型化が避けられなくなることが想定される。   However, it is assumed that by forming the wide rectangular piece 31, the size of the internal terminal 21 having the rectangular piece 31 and the size of the circuit board connector 23 cannot be avoided.

そこで、本発明の実施の形態では、さらに、矩形片31に打出し片53を設ける。この打出し片53は、矩形片31の一部が、外部端子50に近接する方向に突出されたものである。これにより矩形片31を大型化することなく、この矩形片31の一部を使って内部端子21の外部端子50に対する対地静電容量を増加させる(高める)ことができる。この結果、回路基板用コネクタ23のインピーダンスを局所的に高くするように調整することができる。以下、打出し片53を形成した矩形片31を有する内部端子21について詳細に説明する。   Therefore, in the embodiment of the present invention, the punch piece 53 is further provided on the rectangular piece 31. The punching piece 53 is a part in which the rectangular piece 31 is protruded in a direction approaching the external terminal 50. Thereby, without increasing the size of the rectangular piece 31, it is possible to increase (enhance) the ground capacitance of the internal terminal 21 with respect to the external terminal 50 using a part of the rectangular piece 31. As a result, the impedance of the circuit board connector 23 can be adjusted to be locally increased. Hereinafter, the internal terminal 21 having the rectangular piece 31 in which the projecting piece 53 is formed will be described in detail.

図3から図5は、矩形片31に打出し片53を形成した内部端子21を持つ回路基板用コネクタ23を示す。図3は、この回路基板用コネクタ23の縦断面図、図4は、この回路基板用コネクタ23の平断面図、図5は、図3におけるX-X線断面図である。図3から図5において、内部端子21の形状およびサイズは、基本的に図1に示したものと略同じである。連結部27を構成する水平方向部分29には、幅広の(面積の広い)矩形片31が形成されている。   3 to 5 show a circuit board connector 23 having an internal terminal 21 in which a projecting piece 53 is formed on a rectangular piece 31. 3 is a longitudinal sectional view of the circuit board connector 23, FIG. 4 is a plan sectional view of the circuit board connector 23, and FIG. 5 is a sectional view taken along line XX in FIG. 3 to 5, the shape and size of the internal terminal 21 are basically the same as those shown in FIG. A wide (wide) rectangular piece 31 is formed in the horizontal portion 29 constituting the connecting portion 27.

この矩形片31は、絶縁部材51の中心部を貫通する取付孔52に挿入(圧入)可能なサイズ、形状をなす。従って、取付孔52に挿入可能なサイズ、形状であれば、前記矩形以外の例えば多角形片等とすることもできる。なお、絶縁部材51は、円筒状の外部端子50の内周に移動不可能に装着されている。   The rectangular piece 31 has a size and a shape that can be inserted (press-fitted) into a mounting hole 52 that penetrates the central portion of the insulating member 51. Accordingly, a polygonal piece or the like other than the rectangle can be used as long as the size and shape can be inserted into the mounting hole 52. The insulating member 51 is mounted on the inner periphery of the cylindrical external terminal 50 so as not to move.

矩形片31の略中央部には、その矩形片31の下面から上方へ向かって打出し加工された打出し片53が突設されている。この打出し片53は、矩形片31のいずれか一方の面に対してコの字形状の切り込みを施し、その切り込みによって囲まれる部位を一方の面から他方の面に向かって押し出すことにより形成される。以後、矩形片31は、打出し片53と、打出し片53を囲む矩形片本体55と、によって構成されるものとする。このようにして矩形片31に形成された打出し片53は、基部(この基部は、コの字を形作る切り込みの、2つの終端を結ぶ箇所に位置する。)が矩形片本体55に略垂直に立ち上がり、この立ち上がり部に続く部分が矩形片本体55と平行な平坦部となる。この打出し片53はこれの打出し量、つまり矩形片本体55からの高さおよびコの字の形状によって囲まれる面積に応じて外部端子50に対する対地静電容量決まる。このため、打出し量を適宜変更することによって、対地静電容量を調整することができる。なお、打出し片53の立ち上がり部に続く部分の形状は、矩形片本体55によって形成される平面と平行であるものに限らない。別の形状としては、外部端子50の内周面といずれの箇所においても等距離を保つ円弧部としてもよい。   A projecting piece 53 that is ejected upward from the lower surface of the rectangular piece 31 is projected from the substantially central portion of the rectangular piece 31. The punching piece 53 is formed by making a U-shaped cut on one surface of the rectangular piece 31 and pushing a portion surrounded by the cut from one surface toward the other surface. The Henceforth, the rectangular piece 31 shall be comprised by the launch piece 53 and the rectangular piece main body 55 surrounding the launch piece 53. FIG. The punched piece 53 thus formed on the rectangular piece 31 has a base portion (this base portion is located at a position connecting two ends of the cut forming the U-shape) substantially perpendicular to the rectangular piece main body 55. The portion following the rising portion becomes a flat portion parallel to the rectangular piece main body 55. This grounding piece 53 has a grounding electrostatic capacitance with respect to the external terminal 50 determined according to the amount of this sticking, that is, the area surrounded by the height from the rectangular piece body 55 and the U-shaped shape. For this reason, the ground capacitance can be adjusted by appropriately changing the launch amount. The shape of the portion following the rising portion of the launch piece 53 is not limited to being parallel to the plane formed by the rectangular piece body 55. As another shape, it is good also as an arc part which maintains equidistance in the inner peripheral surface of the external terminal 50 in any location.

なお、打出し片53を形成するための切り込みの形状は、コの字に限られるものではない。要は、打出し片53となる矩形片31の一部を一面から他面にかけて押し出すために、矩形片53の一面における任意の二点を結ぶように切り込みを形成しておけばよい。   In addition, the shape of the cut for forming the ejection piece 53 is not limited to the U-shape. In short, in order to extrude a part of the rectangular piece 31 serving as the punching piece 53 from one surface to the other surface, a notch may be formed so as to connect any two points on one surface of the rectangular piece 53.

また、矩形片本体55には、内部端子21の絶縁部材51からの抜けを防ぐための円弧状の切欠32が、矩形片本体55の両側縁の互いに対応する位置に前述のように形成されている。また、絶縁部材51とともに内部端子21を覆うように支持する外部端子50が、絶縁材料からなるコネクタハウジング54内に収納されている。   Further, the rectangular piece main body 55 is formed with arc-shaped cutouts 32 for preventing the internal terminal 21 from coming off from the insulating member 51 at positions corresponding to each other on both side edges of the rectangular piece main body 55 as described above. Yes. In addition, an external terminal 50 that supports the insulating member 51 so as to cover the internal terminal 21 is housed in a connector housing 54 made of an insulating material.

絶縁部材51には、図5に示すように、絶縁部材51の底面から見て凸型の取付孔52が長手方向に貫通するように設けられている。この取付孔52のうち下部の幅広の孔部52aは、底面から見て、矩形片本体55を絶縁部材51の軸方向に沿って挿通できるサイズの長矩形をなす。上部の幅狭の孔部52bは、打出し片53が絶縁部材の軸方向に沿って挿通可能なサイズの長矩形をなす。そして、これらの各孔部52a、52bを合わせた高さは、電気接触部25をその絶縁部材51の一端(図3において、右端)から外へ貫通させることができるサイズともなっている。また、絶縁部材51内周の軸方向の中央部付近には、内側に向けて突出する突起51cが周方向に沿って形成されている。なお、絶縁部材51が僅かでも弾性(伸縮)機能を持つ場合には、その突起を省くこともできる。   As shown in FIG. 5, the insulating member 51 is provided with a convex attachment hole 52 penetrating in the longitudinal direction when viewed from the bottom surface of the insulating member 51. The lower wide hole portion 52 a of the mounting hole 52 has a long rectangular shape that allows the rectangular piece body 55 to be inserted along the axial direction of the insulating member 51 when viewed from the bottom surface. The narrow hole portion 52b at the top forms a long rectangle of a size that allows the projecting piece 53 to be inserted along the axial direction of the insulating member. The combined height of the holes 52a and 52b is a size that allows the electrical contact portion 25 to penetrate from one end (the right end in FIG. 3) of the insulating member 51 to the outside. Further, in the vicinity of the central portion in the axial direction of the inner periphery of the insulating member 51, a protrusion 51c protruding inward is formed along the circumferential direction. In addition, when the insulating member 51 has a slight elasticity (extension / contraction) function, the projection can be omitted.

外部端子50に取り付けられた絶縁部材51に内部端子21を装着する場合には、その内部端子21の電気接触部25の先端を、絶縁部材51の左端側から孔52a、52b内に挿入する。そして、この電気接触部25を孔部52a、52bに貫通させた後、さらに奥深く挿入し、矩形片31を各孔52a、52b内に深く押し込む。   When the internal terminal 21 is attached to the insulating member 51 attached to the external terminal 50, the tip of the electrical contact portion 25 of the internal terminal 21 is inserted into the holes 52a and 52b from the left end side of the insulating member 51. And after making this electrical contact part 25 penetrate the hole parts 52a and 52b, it inserts further deeply and pushes the rectangular piece 31 deeply in each hole 52a and 52b.

この内部端子21の押し込みによって、図3および図4に示すように、矩形片31が孔部52a内の前記幅方向の略中央部に至る。これにより、その絶縁部材51の突起51cに矩形片本体55の切欠32が嵌まり込む。これにより、内部端子21は絶縁部材51および外部端子50に対し軸方向の位置決めと抜け止めがなされ、かつ絶縁部材51内に保持される。   By pushing in the internal terminal 21, the rectangular piece 31 reaches the substantially central portion in the width direction in the hole 52a as shown in FIGS. Thereby, the notch 32 of the rectangular piece body 55 is fitted into the protrusion 51 c of the insulating member 51. As a result, the internal terminal 21 is axially positioned and retained with respect to the insulating member 51 and the external terminal 50, and is held in the insulating member 51.

また、このように矩形片31が絶縁部材51および外部端子50に対し軸方向の位置決めと抜け止めがなされると、打出し片53の平面部(または円弧部)は、孔部52b内にあって外部端子50側に近接した位置に臨む。このため、この打出し片52の平坦部(または円弧部)は外部端子50に対する静電容量を増加するように機能し、この部分のインピーダンスを局所的に高める。この結果、この高インピーダンスは回路基板用コネクタ23と回路基板22との接続部分でのインピーダンスの低下を補い、回路基板用コネクタ23全体のインピーダンスを所望のものにすることを補償する。   In addition, when the rectangular piece 31 is axially positioned and prevented from coming off with respect to the insulating member 51 and the external terminal 50 in this way, the flat portion (or arc portion) of the projecting piece 53 is in the hole 52b. Facing the external terminal 50 side. For this reason, the flat part (or arc part) of this projecting piece 52 functions to increase the capacitance with respect to the external terminal 50, and locally increases the impedance of this part. As a result, this high impedance compensates for a decrease in impedance at the connection portion between the circuit board connector 23 and the circuit board 22 and compensates for the desired impedance of the entire circuit board connector 23.

従って、前述のようなインピーダンスの乱れを解消することができ、また、同軸ケーブル側のインピーダンスとの整合安定的に維持でき、前記接続部分での高周波特性の劣化を最小限に抑えることができる。この場合において、打出し片53の形状およびサイズは、設計段階で前記低インピーダンスの補償値に応じて決定される。   Therefore, the disturbance of the impedance as described above can be eliminated, the matching with the impedance on the coaxial cable side can be maintained stably, and the deterioration of the high frequency characteristics at the connecting portion can be minimized. In this case, the shape and size of the projecting piece 53 are determined in accordance with the low impedance compensation value at the design stage.

以上、本発明の実施の形態では、外部端子50に対する対地静電容量を増加するための打出し片53を矩形片31に設けたことで、回路基板用コネクタ23と回路基板22との接続部分で低くなるインピーダンスの低下分を補い、回路基板用コネクタ23全体のインピーダンスを所望のものにすることができる。この結果、この回路基板用コネクタ23を含む伝送路全体の高周波特性を向上することができる。   As described above, in the embodiment of the present invention, the projecting piece 53 for increasing the ground capacitance with respect to the external terminal 50 is provided in the rectangular piece 31, so that the connection portion between the circuit board connector 23 and the circuit board 22 is provided. Therefore, the impedance decrease of the circuit board connector 23 can be made as desired. As a result, the high frequency characteristics of the entire transmission line including the circuit board connector 23 can be improved.
