オス側同軸コネクタ及びメス側同軸コネクタは、同軸ケーブルの芯線に接続される内導体端子と、同軸ケーブルの編組に接続される外導体端子（シールド端子）と、これら内導体端子及び外導体端子の間に介在する誘電体（絶縁体）と、コネクタ同士の嵌合を行うためのコネクタハウジングとを備えてそれぞれ構成されている。外導体端子は、内導体端子の外側を覆って電磁的にシールドすることができるような形状に形成されている。   The male side coaxial connector and the female side coaxial connector include an inner conductor terminal connected to the core wire of the coaxial cable, an outer conductor terminal (shield terminal) connected to the braid of the coaxial cable, and the inner conductor terminal and the outer conductor terminal. Each is provided with a dielectric (insulator) interposed therebetween and a connector housing for fitting the connectors together. The outer conductor terminal is formed in a shape that covers the outside of the inner conductor terminal and can be electromagnetically shielded.

下記特許文献１に開示された同軸ケーブル用コネクタは、オス側同軸コネクタ及びメス側同軸コネクタの各シールド端子が次のような形状に形成されている。すなわち、シールド端子は、互いに接触し合う電気接触部の形状が断面コ字状となる形状に形成されている。具体的には、対向する一対の側壁と、これらを連結する連結壁と、一対の側壁により形成される上縁開放部とを有して、断面コ字状となる形状に形成されている。   In the coaxial cable connector disclosed in the following Patent Document 1, the shield terminals of the male side coaxial connector and the female side coaxial connector are formed in the following shapes. That is, the shield terminal is formed in a shape in which the shape of the electrical contact portion that contacts each other has a U-shaped cross section. Specifically, it has a pair of side walls that face each other, a connecting wall that connects them, and an upper edge opening formed by the pair of side walls, and is formed in a U-shaped cross section.

上記形状のシールド端子は、オス側同軸コネクタ及びメス側同軸コネクタが嵌合して電気接触部同士が接続状態になると、一方の電気接触部の上縁開放部が他方の電気接触部の連結壁によって覆われるようになる。
特表２００５−５２９４４９号公報 When the male coaxial connector and the female coaxial connector are fitted and the electrical contact portions are connected to each other, the upper edge opening portion of one electrical contact portion is the connecting wall of the other electrical contact portion.

上記従来技術にあっては、シールド端子の電気接触部が断面コ字状に形成されることから、オス側同軸コネクタ及びメス側同軸コネクタが嵌合してシールド端子の電気接触部同士が接続状態になると、接続状態部分の断面形状が矩形状になる。ところが、接続状態部分の理想的な断面形状は一般的に丸形であると言われることから、従来技術にあっては理想形状と形状が違うこととなり、結果、電気的性能の低下が懸念され、これが問題点となっている。   In the above prior art, since the electrical contact part of the shield terminal is formed in a U-shaped cross section, the male side coaxial connector and the female side coaxial connector are fitted and the electrical contact parts of the shield terminal are connected to each other. Then, the cross-sectional shape of the connected state portion becomes rectangular. However, since it is said that the ideal cross-sectional shape of the connected portion is generally round, in the prior art, the ideal shape is different from the shape, and as a result, there is a concern about a decrease in electrical performance. This is a problem.

この他、シールド端子に限ることでないが、端子の小型化やコスト低減を図ることについての要望は常にあり、対応する必要がある。   In addition, although not limited to shield terminals, there is always a demand for miniaturization of terminals and cost reduction, and it is necessary to respond.

本発明は、上記した事情に鑑みてなされたもので、電気的性能の低下を防止し、小型化及びコスト低減も図ることが可能な同軸ケーブル用コネクタを提供することを課題とする。   The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a coaxial cable connector that can prevent a reduction in electrical performance, and can be reduced in size and cost.

上記課題を解決するためになされた請求項１記載の本発明の同軸ケーブル用コネクタは、各同軸ケーブルの端末に設けられるオス側同軸コネクタとメス側同軸コネクタとを備えて構成される同軸ケーブル用コネクタにおいて、前記オス側同軸コネクタを構成するオス側シールド端子は、前記同軸ケーブルの編組に接続されるオス側編組接続部と、半円筒形状に形成され且つ端子軸に沿ってのびる一対の端面を有するオス側電気接触部とを含み、前記メス側同軸コネクタを構成するメス側シールド端子は、前記同軸ケーブルの編組に接続されるメス側編組接続部と、前記オス側電気接触部に対する電気的接続部としてのメス側電気接触部とを含み、該メス側電気接触部は、略半円筒形状の略半円筒部と、該略半円筒部に形成され且つ前記オス側電気接触部の前記一対の端面をそれぞれ受ける一対の相手端子受け部と、端子軸に交差する方向にのび且つ前記一対の相手端子受け部が前記オス側電気接触部を受けた時に該オス側電気接触部の外面に接触する片持ち形状の相手端子接触バネ部と、前記略半円筒部に連続し且つ前記メス側電気接触部の形成時に合わせ目が生じ且つ前記相手端子接触バネ部が連成される端子合わせ目部とを有することを特徴としている。   The coaxial cable connector of the present invention according to claim 1 made to solve the above-mentioned problems is for a coaxial cable configured to include a male-side coaxial connector and a female-side coaxial connector provided at the end of each coaxial cable. In the connector, the male side shield terminal constituting the male side coaxial connector has a male side braid connection portion connected to the braid of the coaxial cable, and a pair of end faces formed in a semi-cylindrical shape and extending along the terminal axis.

A pair of mating terminal receiving portions formed on the portion. Accordingly, when the electrical contact portions of the male and female shield terminals are in a connected state, the cross-sectional shape of the connected state portion is substantially round. Since the male-side electrical contact portion contacts the counterpart terminal contact spring portion in addition to the pair of counterpart terminal receiving portions in the female-side electrical contact portion, the contact portion is sufficiently secured. According to the present invention, since the electrical contact portion has a semi-cylindrical shape, at least this portion is small. Further, the cost is reduced by the amount that is reduced.

The cylindrical portion 23 is formed as a portion for matching impedance.

以上、図１ないし図３を参照しながら説明してきたように、本発明によれば、オス側シールド端子１は、半円筒形状のオス側電気接触部２を有しており、メス側シールド端子２１は、このメス側電気接触部２２に、略半円筒形状の略半円筒部２６と、一対の相手端子受け部２８とを有している。従って、オス側同軸コネクタ及びメス側同軸コネクタが嵌合し合い、オス側電気接触部２及びメス側電気接触部２２同士が図３（ｂ）に示す如く接続状態となると、この接続状態部分の断面形状は、ほぼ理想的な略丸形になり、結果、電気的性能の低下を防止することができる。   As described above with reference to FIGS. 1 to 3, according to the present invention, the male shield terminal 1 has the semi-cylindrical male electrical contact portion 2, and the female shield terminal. 21 has a substantially semi-cylindrical substantially semi-cylindrical portion 26 and a pair of mating terminal receiving portions 28 on the female-side electrical contact portion 22. Accordingly, when the male side coaxial connector and the female side coaxial connector are fitted to each other and the male side electrical contact portion 2 and the female side electrical contact portion 22 are connected to each other as shown in FIG. The cross-sectional shape becomes a substantially ideal substantially round shape, and as a result, a decrease in electrical performance can be prevented.

この他、本発明によれば、オス側電気接触部２及びメス側電気接触部２２がそれぞれ半円筒形状となる構造を有することから、この半円筒形状となる構造によって小型化を図ることができる。また、小型化の分だけコスト低減も図ることができる。   In addition, according to the present invention, since the male-side electrical contact portion 2 and the female-side electrical contact portion 22 each have a semi-cylindrical shape, it is possible to reduce the size by the semi-cylindrical structure. . Further, the cost can be reduced by the size reduction.

本発明は本発明の主旨を変えない範囲で種々変更実施可能なことは勿論である。   It goes without saying that the present invention can be variously modified without departing from the spirit of the present invention.
