図１２の斜視図に示したコネクタ端子５１０においては、端子本体５１１から延在した２つの板状の接触部５１２ａ、５１２ｂが、端子本体５１１に対して直角に曲げられており、これらの接触部５１２ａ、５１２ｂ間に相手コネクタ端子を挟む構造となっている。図１３（ｄ）に示すように、電子機器側の相手コネクタ２は、相手コネクタ端子２ａ、絶縁体２ｂ、外部導体２ｃを有しており、コネクタ端子同士の接触領域における径方向断面図である図１３（ｅ）に示すように、相手コネクタ端子２ａと接触部５１２ａ、５１２ｂとが接触することにより相手コネクタ端子２ａとコネクタ端子５１０とが電気的に接続されている。 In the connector terminal 510 shown in the perspective view of FIG. 12, two plate-like contact portions 512a and 512b extending from the terminal body 511 are bent at a right angle with respect to the terminal body 511, and these contact portions. A mating connector terminal is sandwiched between 512a and 512b.

しかしながら、２枚の板状のコネクタ端子を用いるコネクタでは、以下のような問題が生じる。 However, a connector using two plate-like connector terminals has the following problems.

すなわち、図１３（ｅ）に示すように、相手コネクタ端子の断面形状が環状であるのに対し、コネクタ端子の断面形状が直線状であり、両者の接触部分の断面形状に大きな違いがある。そのため、同軸ケーブルによって高周波信号を伝送する場合に、コネクタ端子と相手コネクタ端子との間において、特性インピーダンスの不整合により電圧定在波比（ＶＳＷＲ（Voltage Standing Wave Ratio））が増大し、電気信号の伝送ロスが大きくなる。その結果、同軸ケーブルによる高周波信号を含む広帯域信号の効率的な伝送ができない。 That is, as shown in FIG. 13 (e), the cross-sectional shape of the mating connector terminal is annular, whereas the cross-sectional shape of the connector terminal is linear, and there is a great difference in the cross-sectional shape of the contact portion between them. Therefore, when a high frequency signal is transmitted through a coaxial cable, a voltage standing wave ratio (VSWR (Voltage Standing Wave Ratio)) increases between the connector terminal and the mating connector terminal due to the mismatch of characteristic impedance, and the electric signal Transmission loss increases. As a result, it is impossible to efficiently transmit a broadband signal including a high-frequency signal using a coaxial cable.

そこで、本発明は、同軸ケーブルによる高周波信号を含む広帯域信号の効率的な伝送を可能とするコネクタ端子及びその製造方法並びにコネクタを提供することを目的とする。 Therefore, an object of the present invention is to provide a connector terminal, a manufacturing method thereof, and a connector that enable efficient transmission of a broadband signal including a high-frequency signal by a coaxial cable.

The coaxial cable 50 has an inner conductor 51, an insulator 52, an outer conductor 53, and a jacket 54 in this order from the radial center. The inner conductor 51 is passed through the opening 15 provided in the holding surface 16 of the inner conductor connecting portion 14 of the connector terminal 10 and is soldered to the inner conductor connecting portion 14 so that the inner conductor 51 is electrically connected to the connector terminal 10. It is connected to the. The outer conductor 53 of the coaxial cable 50 is electrically connected to the shell 30 at the outer conductor connecting portion 31.

A housing 40 is housed in the main body 32. An annular space 20 is formed between the main body portion 41 of the housing 40 and the main body portion 32 of the shell 30 to receive an external conductor of a mating connector described later.

次に、図２、図３を用いて本発明の一実施形態に係るコネクタ端子１０について説明する。図２（ａ）〜（ｅ）は図１のＬ型同軸コネクタ１と相手コネクタ２との接続状態を示した図である。図２（ａ）は上面図、図２（ｂ）は側面図、図２（ｃ）は図２（ａ）のＡ−Ａ’断面図、図２（ｄ）は図２（ｂ）のＢ−Ｂ’断面図、図２（ｅ）は図２（ｂ）のＣ−Ｃ’断面図をそれぞれ示している。相手コネクタ２の構成は、前述した図１３（ｄ）における相手コネクタ２の構成と同一であり、相手コネクタ端子２ａ、絶縁体２ｂ、外部導体２ｃを有している。 Next, the connector terminal 10 which concerns on one Embodiment of this invention using FIG. 2, FIG. 3 is demonstrated. FIGS. 2A to 2E are views showing a connection state between the L-shaped coaxial connector 1 and the mating connector 2 of FIG. 2A is a top view, FIG. 2B is a side view, FIG. 2C is a cross-sectional view along AA ′ in FIG. 2A, and FIG. 2D is B in FIG. -B 'sectional drawing and FIG.2 (e) have each shown CC' sectional drawing of FIG.2 (b). The configuration of the mating connector 2 is the same as the configuration of the mating connector 2 in FIG. 13D described above, and includes a mating connector terminal 2a, an insulator 2b, and an external conductor 2c.

図２（ｅ）に示すように、本実施形態に係るＬ型同軸コネクタ１では、コネクタ端子１０の筒状部１２の断面形状が、相手コネクタ端子２ａの断面形状と同様にほぼ環状となっており、筒状部１２が相手コネクタ２ａを取り囲むようにして両者が接続されている。 As shown in FIG. 2 (e), in the L-shaped coaxial connector 1 according to the present embodiment, the cross-sectional shape of the tubular portion 12 of the connector terminal 10 is substantially annular, similar to the cross-sectional shape of the mating connector terminal 2a. The two are connected so that the cylindrical portion 12 surrounds the mating connector 2a.

図３（ａ）は図１に示す本発明の一実施形態に係るコネクタ端子１０の斜視図である。図３（ａ）に示すように、コネクタ端子１０は、環状の端子本体１１と、端子本体１１の図面において下面から延在する筒状部１２と、端子本体１１の端部から外側に延在した内部導体接続部１４とを有している。筒状部１２には、その軸方向に伸びる２本のスリット１３が形成されており、これによりばね構造が得られ、筒状部１２の内部に、相手コネクタ端子２ａが嵌挿される。ここで、コネクタ端子間の安定した接続のため、相手コネクタ端子２ａの外径よりも筒状部１２の内径を小さく設計している。内部導体接続部１４は、端子本体１１の図面において上面と直交し且つ同軸ケーブル５０の内部導体５１の外径とほぼ同じ径の開口１５が形成された保持面１６を有している。ここで、コネクタ端子１０の筒状部１２は、後述するように、絞り加工によって形成されたものである。 FIG. 3A is a perspective view of the connector terminal 10 according to the embodiment of the present invention shown in FIG. As shown in FIG. 3A, the connector terminal 10 includes an annular terminal body 11, a cylindrical part 12 extending from the lower surface in the drawing of the terminal body 11, and an outer side extending from the end of the terminal body 11. Internal conductor connection portion 14. Two slits 13 extending in the axial direction are formed in the cylindrical portion 12, whereby a spring structure is obtained, and the mating connector terminal 2 a is inserted into the cylindrical portion 12. Here, in order to stably connect the connector terminals, the inner diameter of the cylindrical portion 12 is designed to be smaller than the outer diameter of the mating connector terminal 2a. The inner conductor connecting portion 14 has a holding surface 16 in which an opening 15 that is orthogonal to the upper surface in the drawing of the terminal body 11 and has substantially the same diameter as the outer diameter of the inner conductor 51 of the coaxial cable 50 is formed. Here, the cylindrical portion 12 of the connector terminal 10 is formed by drawing as described later.

図３（ｂ）は図３（ａ）のコネクタ端子１０と同軸ケーブル５０の内部導体５１との接続状態を示した図である。図３（ｂ）に示すように、内部導体５１の先端部は開口１５を貫通し、内部導体接続部１４においてコネクタ端子１０にはんだ付けされている（図３（ｂ）の７００）。 FIG. 3B is a view showing a connection state between the connector terminal 10 of FIG. 3A and the inner conductor 51 of the coaxial cable 50. As shown in FIG. 3B, the tip of the inner conductor 51 passes through the opening 15 and is soldered to the connector terminal 10 at the inner conductor connecting portion 14 (700 in FIG. 3B).

Ｌ型同軸コネクタ１においては、相手コネクタ端子２ａの断面形状が環状であるのに対して、コネクタ端子１０の断面形状もほぼ環状となるために、図１３（ｅ）に示す従来の同軸コネクタ５と比較して、相手コネクタ端子２ａとコネクタ端子１０との接触部分における断面形状の差が小さくなっている。そのため、同軸ケーブル５０によって高周波信号を伝送する場合に、同軸ケーブルとコネクタ端子との間及びコネクタ端子と相手コネクタ端子との間において特性インピーダンスの不整合により電圧定在波比が大きくならないので、電気信号の伝送ロスを少なくすることができる。その結果、同軸ケーブル５０による高周波信号を含む広帯域信号の効率的な伝送が可能となる。 In the L-type coaxial connector 1, the cross-sectional shape of the mating connector terminal 2 a is annular, whereas the cross-sectional shape of the connector terminal 10 is also substantially annular. Therefore, the conventional coaxial connector 5 shown in FIG. As compared with the above, the difference in cross-sectional shape at the contact portion between the mating connector terminal 2a and the connector terminal 10 is small. Therefore, when a high-frequency signal is transmitted through the coaxial cable 50, the voltage standing wave ratio does not increase due to the mismatch of characteristic impedance between the coaxial cable and the connector terminal and between the connector terminal and the mating connector terminal. Signal transmission loss can be reduced. As a result, it is possible to efficiently transmit a broadband signal including a high-frequency signal through the coaxial cable 50.

また、本実施形態に係るコネクタ端子１０には、端子本体１１の端部から外側に延在した内部導体接続部１４が設けられているため、同軸ケーブル５０の内部導体５１とコネクタ端子１０とのはんだ付けによる接続領域を広く確保でき、同軸ケーブル５０とコネクタ端子１０との間の伝送効率が向上する。 Further, since the connector terminal 10 according to the present embodiment is provided with the inner conductor connecting portion 14 that extends outward from the end portion of the terminal body 11, the inner conductor 51 of the coaxial cable 50 and the connector terminal 10 are connected to each other. A wide connection area by soldering can be secured, and the transmission efficiency between the coaxial cable 50 and the connector terminal 10 is improved.

また、本実施形態に係るコネクタ端子１０において、内部導体接続部１４には、端子本体１１の側面と直交し且つ同軸ケーブル５０の内部導体５１の外径とほぼ同じ径の開口１５が形成された保持面１６が設けられている。開口１５を円形にすることにより、同軸ケーブル５０の位置決めが容易になり、はんだ付けの作業性が向上する。そして、コネクタ端子１０が微小なものであっても、コネクタ端子１０と同軸ケーブル５０の内部導体５１との接続位置のずれを防止することができるため、製品の伝送能力などの品質を安定化できる。また、保持面１６ははんだの流出を防止する機能も有している。 In the connector terminal 10 according to the present embodiment, the inner conductor connecting portion 14 is formed with an opening 15 that is orthogonal to the side surface of the terminal body 11 and has the same diameter as the outer diameter of the inner conductor 51 of the coaxial cable 50. A holding surface 16 is provided. By making the opening 15 circular, positioning of the coaxial cable 50 is facilitated, and soldering workability is improved. And even if the connector terminal 10 is very small, it is possible to prevent displacement of the connection position between the connector terminal 10 and the inner conductor 51 of the coaxial cable 50, so that quality such as product transmission capability can be stabilized. . The holding surface 16 also has a function of preventing the solder from flowing out.

また、筒状部１２が絞り加工によって形成されたものであるので、コネクタ端子１０を、微小なものであっても、簡易な方法で製造することができる。 Moreover, since the cylindrical part 12 is formed by drawing, even if the connector terminal 10 is very small, it can be manufactured by a simple method.

次に、図７〜図１１を用いて、本発明に係るコネクタ端子１０の製造方法の一実施形態について説明する。図７〜図１１はそれぞれ図１に示すコネクタ端子１０の製造工程における一工程を示した図であり、それぞれにおいて、（ａ）は上面図、（ｂ）は（ａ）の側面図、（ｃ）は（ａ）のＧ−Ｇ’断面図を示している。 Next, an embodiment of a method for manufacturing the connector terminal 10 according to the present invention will be described with reference to FIGS. 7 to 11 are views showing one process in the manufacturing process of the connector terminal 10 shown in FIG. 1, in which (a) is a top view, (b) is a side view of (a), and (c). ) Shows a GG ′ cross-sectional view of (a).

次に、上記のように形成された筒状部１１に対して、図１０に示すように、打ち抜き加工によりその軸方向に伸びる２本のスリット１３を形成する。ここでは打ち抜き加工によるが、この方法には限られない。 (Slit processing)
Next, as shown in FIG. 10, two slits 13 extending in the axial direction are formed by punching the cylindrical portion 11 formed as described above. Although it is based on punching here, it is not limited to this method.

（曲げ工程）
次に、図１１に示すように、延出部２０２を開口１５よりも内側の位置で折り曲げることによって、筒状部１２の軸方向に延びた保持面１６を形成する。ここで、端子本体１１の端部から外側に延在した部分が内部導体接続部１４となる。以上のようにしてコネクタ端子１０を製造することが出来る。
(Bending process)
Next, as shown in FIG. 11, the holding surface 16 extending in the axial direction of the tubular portion 12 is formed by bending the extending portion 202 at a position inside the opening 15. Here, the portion extending outward from the end portion of the terminal body 11 becomes the internal conductor connecting portion 14. The connector terminal 10 can be manufactured as described above.

本実施形態に係るコネクタ端子１０の製造方法では、平板状部材６００に対して絞り加工を施すことによって、環状の端子本体１１と、端子本体１１の一側面から延在した筒状部１２とを形成する絞り加工工程と、絞り加工工程で形成された筒状部１２に対して、その軸方向に伸びる２本のスリット１３を形成するスリット形成工程を有しているために、同軸ケーブル５０による高周波信号を含む広帯域信号の効率的な伝送が可能となるコネクタ端子１０を、微小なものであっても、平板状部材６００から簡易な方法で製造することができる。 In the manufacturing method of the connector terminal 10 according to the present embodiment, the flat plate member 600 is subjected to a drawing process so that the annular terminal body 11 and the cylindrical portion 12 extending from one side surface of the terminal body 11 are obtained. The coaxial cable 50 has a drawing process for forming and a slit forming process for forming two slits 13 extending in the axial direction of the cylindrical portion 12 formed in the drawing process. Even if the connector terminal 10 capable of efficiently transmitting a broadband signal including a high-frequency signal is minute, it can be manufactured from the flat plate member 600 by a simple method.

また、本実施形態に係るコネクタ端子１０の製造方法では、絞り工程が、平板上部材６００に対して絞り加工を施すことによって、平板状部材６００の一側面から突出し且つ底面を有する突出部６０３を形成する第１の絞り加工工程と、突出部６０３の底面に対して絞り加工を施すことによって、環状の端子本体１１と、端子本体１１の一側面から延在した筒状部１２とを形成する第２の絞り加工工程とを有しているために、筒状部１１を効率的に形成できる。 Moreover, in the manufacturing method of the connector terminal 10 according to the present embodiment, the drawing step performs drawing processing on the flat plate member 600 so that the protruding portion 603 protruding from one side surface of the flat plate member 600 and having a bottom surface is formed. The annular terminal body 11 and the cylindrical portion 12 extending from one side surface of the terminal body 11 are formed by performing a drawing process on the first drawing process to be formed and the bottom surface of the protrusion 603. Since it has a 2nd drawing process, the cylindrical part 11 can be formed efficiently.

さらに、本実施形態に係るコネクタ端子１０の製造方法では、端子本体１１の外周縁から外側に延在した部分に同軸ケーブル５０の内部導体５１の外径とほぼ同じ径の開口１５を形成する開口形成工程と、端子本体１１の外周縁から外側に延在した部分を折り曲げることによって、筒状部１２の軸方向に延びた保持面１６を形成する曲げ工程とを有しているために、同軸ケーブル５０の内部導体５１とコネクタ端子１０との接続領域を、簡易な方法で広く確保することができ、同軸ケーブル５０とコネクタ端子１０の間の伝送効率が向上する。また、コネクタ端子１０と同軸ケーブル５０の内部導体５１との接続位置のずれを防止するための保持面１６及び開口１５を簡易な方法で形成することができる。なお、保持面１６を形成することで、保持面と端子本体１１の外周縁との間には、筒状部１２の軸方向と直交する中間面が形成される。保持面１６に形成された開口１５は、中間面と同じ高さから、保持面１６内を筒状部１２から離れる方向に延在している。端子本体１１の外周縁には導体接続部１４だけが接続されている。 Furthermore, in the method for manufacturing the connector terminal 10 according to the present embodiment, the opening 15 having the same diameter as the outer diameter of the inner conductor 51 of the coaxial cable 50 is formed in a portion extending outward from the outer peripheral edge of the terminal body 11. Since there is a forming step and a bending step of forming the holding surface 16 extending in the axial direction of the cylindrical portion 12 by bending a portion extending from the outer peripheral edge of the terminal body 11 to the outside, it is coaxial. A connection region between the inner conductor 51 of the cable 50 and the connector terminal 10 can be secured widely by a simple method, and the transmission efficiency between the coaxial cable 50 and the connector terminal 10 is improved. Moreover, the holding surface 16 and the opening 15 for preventing the displacement of the connection position between the connector terminal 10 and the inner conductor 51 of the coaxial cable 50 can be formed by a simple method. In addition, by forming the holding surface 16, an intermediate surface orthogonal to the axial direction of the tubular portion 12 is formed between the holding surface and the outer peripheral edge of the terminal body 11. The opening 15 formed in the holding surface 16 extends from the same height as the intermediate surface in a direction away from the cylindrical portion 12 in the holding surface 16. Only the conductor connecting portion 14 is connected to the outer peripheral edge of the terminal body 11.

次に、図４〜図６を用いて、本実施の形態に係るコネクタ端子１０の変形例について説明する。図４〜図６は、本実施の形態に係るコネクタ端子１０の変形例の斜視図であり、図４は第１変形例、図５は第２変形例、図６は第３変形例を示している。 Next, a modified example of the connector terminal 10 according to the present embodiment will be described with reference to FIGS. 4 to 6 are perspective views of modifications of the connector terminal 10 according to the present embodiment. FIG. 4 shows a first modification, FIG. 5 shows a second modification, and FIG. 6 shows a third modification. ing.

図４に示すように、第１変形例に係るコネクタ端子２１０については、スリット２１３の幅がコネクタ端子１０のスリット１３よりも広くなっている。また、図５に示すように、第２変形例に係るコネクタ端子３１０については、スリット３１３の数が４本であり、コネクタ端子１０よりも多い。また、図６に示すように、第３変形例に係るコネクタ端子４１０については、スリット４１３の数が１本であり、コネクタ端子１０よりも少ない。その他の部分は、コネクタ端子１０の各部分に対応しているので説明を省略する。このように、本実施の形態に係るコネクタ端子１０は用途に応じた変形が可能である。 As shown in FIG. 4, in the connector terminal 210 according to the first modification, the width of the slit 213 is wider than the slit 13 of the connector terminal 10. Further, as shown in FIG. 5, the connector terminal 310 according to the second modification has four slits 313 and is larger than the connector terminal 10. Also, as shown in FIG. 6, the connector terminal 410 according to the third modification has one slit 413 and is smaller than the connector terminal 10. The other portions correspond to the respective portions of the connector terminal 10 and will not be described. Thus, the connector terminal 10 according to the present embodiment can be modified according to the application.

本実施形態に係るＬ型同軸コネクタの信号伝送性能を評価するため、電圧定在波比の周波数特性を計算した。ここでは、本実施形態に係るコネクタ端子１０を用いたＬ型同軸コネクタ１、本実施形態の変形例に係るコネクタ端子２１０、３１０、４１０を用いたＬ型同軸コネクタ、さらに比較例として、従来のコネクタ端子５１０を用いたＬ型同軸コネクタ５を計算の対象としている。コネクタ端子１０、２１０、３１０、４１０、５１０をそれぞれ相手コネクタ端子２ａと接続した状態で、同軸ケーブル５０からＬ型同軸コネクタを介して相手コネクタ２へ電気信号を伝送する場合の入力電圧値と、相手コネクタ２側での出力電圧値とから、各周波数に対応した電圧定在波比を計算した。 In order to evaluate the signal transmission performance of the L-shaped coaxial connector according to this embodiment, the frequency characteristic of the voltage standing wave ratio was calculated. Here, the L-type coaxial connector 1 using the connector terminal 10 according to the present embodiment, the L-type coaxial connector using the connector terminals 210, 310, 410 according to the modification of the present embodiment, and a comparative example, The L-type coaxial connector 5 using the connector terminal 510 is a calculation target. An input voltage value when an electrical signal is transmitted from the coaxial cable 50 to the mating connector 2 via the L-shaped coaxial connector in a state where the connector terminals 10, 210, 310, 410, 510 are connected to the mating connector terminal 2a, The voltage standing wave ratio corresponding to each frequency was calculated from the output voltage value on the mating connector 2 side.

図１４〜図１８にその計算結果を示した。図１４〜図１８は、コネクタ端子１０、２１０、３１０、４１０及び従来のコネクタ端子５１０を用いたＬ型同軸コネクタについての、電圧定在波比の周波数特性を示したものである。 The calculation results are shown in FIGS. 14 to 18 show the frequency characteristics of the voltage standing wave ratio for the L-type coaxial connector using the connector terminals 10, 210, 310, 410 and the conventional connector terminal 510.

電圧定在波比は、電気信号の伝送経路において反射波が全くない場合に１となる。従って、この値が小さく、且つ１に近いほど反射が少なく、電気信号の伝送ロスが少ない。一般に、伝送機器の信号伝送性能を示す基準として、電圧定在波比が１〜１．５の範囲内に収まる周波数帯域が用いられており、この周波数帯域では信号伝送可能と評価できる。計算の結果、図１４〜図１８について、電圧定在波比が１〜１．５の範囲内にある周波数帯域は、それぞれ以下のようになった。
（１）図１４：０〜１２.０ＧＨｚ以上
（２）図１５：０〜１２.０ＧＨｚ以上
（３）図１６：０〜約１１．８ＧＨｚ
（４）図１７：０〜約１１．８ＧＨｚ
（５）図１８：０〜約７．７ＧＨｚ The voltage standing wave ratio is 1 when there is no reflected wave in the electric signal transmission path. Therefore, the smaller this value is and the closer it is to 1, the less the reflection and the less the transmission loss of the electric signal. In general, a frequency band in which the voltage standing wave ratio falls within a range of 1 to 1.5 is used as a reference indicating the signal transmission performance of a transmission device, and it can be evaluated that signal transmission is possible in this frequency band. As a result of the calculation, with respect to FIGS. 14 to 18, the frequency bands in which the voltage standing wave ratio is in the range of 1 to 1.5 are as follows.
(1) FIG. 14: 0 to 12.0 GHz or more (2) FIG. 15: 0 to 12.0 GHz or more (3) FIG. 16: 0 to about 11.8 GHz
(4) FIG. 17: 0 to about 11.8 GHz
(5) FIG. 18: 0 to about 7.7 GHz

この結果に示すように、従来のコネクタ端子５１０（図１８）を用いた場合に比べて、本実施形態に係るコネクタ端子１０（図１４）を用いた場合に、より高周波の信号の伝送が可能となった。 As shown in this result, it is possible to transmit a higher frequency signal when the connector terminal 10 (FIG. 14) according to the present embodiment is used than when the conventional connector terminal 510 (FIG. 18) is used. It became.

また、本実施の形態に係るコネクタ端子を用いた場合（図１４〜図１７）において、０〜約１２ＧＨｚの周波数帯域に亘って電圧定在波比が１〜１．５の範囲内に収まっており、従来のコネクタ端子５１０を用いた場合（図１８）に比べて、高周波信号を含む広帯域信号のより効率的な伝送が可能となった。 When the connector terminal according to the present embodiment is used (FIGS. 14 to 17), the voltage standing wave ratio falls within the range of 1 to 1.5 over the frequency band of 0 to about 12 GHz. Therefore, compared with the case where the conventional connector terminal 510 is used (FIG. 18), it has become possible to transmit a broadband signal including a high frequency signal more efficiently.

ここではＬ型同軸コネクタ側に電気信号を入力し、相手コネクタ２側における出力値を計算したが、入力、出力の方向が逆であってもほぼ同様の結果となると考えられる。 Here, an electric signal is input to the L-shaped coaxial connector side, and an output value on the mating connector 2 side is calculated. However, it is considered that substantially the same result is obtained even if the input and output directions are reversed.

以上、本発明の好適な実施の形態について説明したが、本発明は上述の実施の形態に限られるものではなく、特許請求の範囲に記載した限りにおいて様々な変更が可能なものである。 The preferred embodiments of the present invention have been described above.

また、開口１５の径を内部導体５１の外径より大きく、且つ、絶縁体５２の外径より小さく設計することで、内部導体５１のみを開口１５に通し、絶縁体５２の端面を保持面１６に当接させることができるため、同軸ケーブル５０の位置決めを容易にすることができる。 Further, by designing the diameter of the opening 15 to be larger than the outer diameter of the inner conductor 51 and smaller than the outer diameter of the insulator 52, only the inner conductor 51 passes through the opening 15, and the end face of the insulator 52 serves as the holding surface 16. Therefore, the coaxial cable 50 can be easily positioned.
