Description

本願の特許請求の範囲に記載された発明は、回路基板に取り付けられて、当該回路基板から外部への、あるいは、外部から当該回路基板への、電磁波シールドが必要とされる信号の伝達に供される同軸コネクタ装置に関する。   The invention described in the claims of the present application is attached to a circuit board and serves to transmit a signal that requires electromagnetic shielding from the circuit board to the outside or from the outside to the circuit board. The present invention relates to a coaxial connector device.

回路基板に配された導体を流れる高周波信号は、当該回路基板から外部へと、あるいは、外部から当該回路基板へと伝送されるにあたり、外部からのノイズの混入防止,外部への漏洩防止等のため、電磁波シールドが必要である信号として扱われることが多い。このような、電磁波シールドが必要である信号についての、特定の回路基板から他の回路基板等の外部への伝送、あるいは、特定の回路基板への他の回路基板等の外部からの伝送が行われるに際しては、当該特定の回路基板に取り付けられるものとされる同軸コネクタ装置が用いられる。   When a high-frequency signal flowing through a conductor arranged on a circuit board is transmitted from the circuit board to the outside or from the outside to the circuit board, noise from the outside is prevented and leakage to the outside is prevented. Therefore, it is often handled as a signal that requires an electromagnetic wave shield. Such signals that require electromagnetic shielding are transmitted from a specific circuit board to the outside such as another circuit board or from the outside such as another circuit board to the specific circuit board. In this case, a coaxial connector device that is attached to the specific circuit board is used.

回路基板に取り付けられる同軸コネクタ装置は、通常、絶縁基体に、信号の伝達に供される信号接続導体と、信号接続導体に供給される信号に対する電磁波シールド作用をもたらすべく接地電位を伝達する接地接触導体と、が配されて構成される。そして、その使用に際しては、例えば、他の回路基板に取り付けられた他の同軸コネクタ装置と嵌合接続される状態におかれ、その信号接続導体が、他の同軸コネクタ装置における信号導体に係合接触するとともに、その接地接続導体が、他の同軸コネクタ装置における接地導体に係合接触するものとされる。それにより、伝送されるにあたって電磁波シールドが必要とされる信号の信号接続導体を通じた回路基板間における伝送が、信号接続導体と共に絶縁基体に配された接地接続導体による電磁波シールドが果たされるもとで行われる。   A coaxial connector device attached to a circuit board usually has a ground contact that transmits a ground potential so as to provide a signal connection conductor for signal transmission and an electromagnetic wave shielding action for the signal supplied to the signal connection conductor to an insulating substrate. And a conductor. In use, for example, the signal connection conductor is engaged with a signal conductor in another coaxial connector device in a state of being fitted and connected to another coaxial connector device attached to another circuit board. At the same time, the ground connection conductor engages and contacts the ground conductor in another coaxial connector device. As a result, transmission between the circuit boards through the signal connection conductor of a signal that requires an electromagnetic shield for transmission is performed by the ground connection conductor arranged on the insulating base together with the signal connection conductor. Done.

斯かる回路基板に取り付けられる同軸コネクタ装置として、平板状を成す絶縁基体に、円筒形状を成す信号接続導体と、信号接続導体を包囲する円筒形状を成す接地接続導体とが配されて構成されたものが、従来提案されている(例えば、特許文献1参照。)。   As a coaxial connector device attached to such a circuit board, a cylindrical signal connection conductor and a cylindrical ground connection conductor surrounding the signal connection conductor are arranged on a flat insulating substrate. The thing is proposed conventionally (for example, refer patent document 1).

特許文献1に開示されている従来提案されている同軸コネクタ装置(同軸コネクタプラグ(10)) にあっては、平板状を成す絶縁基体(絶縁体(16)) に、円筒形状を成す信号接続導体(中心導体(14a))と円筒形状を成す接地接続導体(外部導体(12a))とが、接地接続導体が信号接続導体を包囲するものとされて配されており、これらの信号接続導体及び接地接続導体の夫々は、一体構造をとるものとされている。そして、このような従来提案されている同軸コネクタ装置は、フレキシブルプリント基板のような回路基板上に実装されたもとで、それに他の同軸コネクタ装置(同軸コネクタレセプタクル(110))が装着されるものとされ、その際には、円筒形状を成す信号接続導体の内側に他の同軸コネクタ装置の円柱形状を成す信号導体(中心導体(114a))が挿入されて信号接続導体に係合接触接続されるとともに、円筒形状を成す接地接続導体の内側に他の同軸コネクタ装置の円筒形状を成す接地導体(外部導体(112a))が挿入されて接地接続導体に係合接触接続される。   In the conventionally proposed coaxial connector device (coaxial connector plug (10)) disclosed in Patent Document 1, a cylindrical signal connection is made to a flat insulating substrate (insulator (16)). A conductor (center conductor (14a)) and a cylindrical ground connection conductor (external conductor (12a)) are arranged such that the ground connection conductor surrounds the signal connection conductor. Each of the ground connection conductor and the ground connection conductor has an integral structure. And, such a conventionally proposed coaxial connector device is mounted on a circuit board such as a flexible printed circuit board, and another coaxial connector device (coaxial connector receptacle (110)) is mounted thereon. In this case, a signal conductor (center conductor (114a)) having a cylindrical shape of another coaxial connector device is inserted inside the signal connection conductor having a cylindrical shape and engaged and connected to the signal connection conductor. At the same time, a cylindrical grounding conductor (external conductor (112a)) of another coaxial connector device is inserted inside the cylindrical grounding connection conductor and engaged and connected to the grounding connection conductor.

斯かるもとで、円筒形状を成す信号接続導体には、各々が信号接続導体の仮想中心軸(z軸)に沿う方向に伸びる3個のスリットが設けられており、それにより、他の同軸コネクタ装置の信号導体が信号接続導体の内側に挿入されるときには、他の同軸コネクタ装置の信号導体によって信号接続導体が各スリットの幅を広げるようにして外側に押し広げられ、他の同軸コネクタ装置の信号導体の信号接続導体に対する接触接続が確実に行われるようにされている。また、円筒形状を成す接地接続導体には、その仮想中心軸(z軸)に沿う方向に伸びる1個のスリット(S) が設けられており、それにより、他の同軸コネクタ装置の接地導体が接地接続導体の内側に挿入されるときには、他の同軸コネクタ装置の接地導体によって接地接続導体がスリット(S) の幅を広げるようにして外側に押し広げられ、他の同軸コネクタ装置の接地導体の接地接続導体に対する係合接触接続が確実に行われるようにされている。   Under such circumstances, the cylindrical signal connection conductor is provided with three slits each extending in a direction along the imaginary central axis (z-axis) of the signal connection conductor. When the signal conductor of the connector device is inserted inside the signal connection conductor, the signal connection conductor is pushed outward by the signal conductor of the other coaxial connector device so as to widen the width of each slit. The contact connection of the signal conductor to the signal connection conductor is ensured. In addition, the cylindrical ground connection conductor is provided with one slit (S) extending in the direction along the imaginary central axis (z-axis), so that the ground conductor of other coaxial connector devices can be connected. When inserted inside the ground connection conductor, the ground connection conductor of the other coaxial connector device is pushed outward by widening the slit (S) by the ground conductor of the other coaxial connector device. Engagement contact connection to the ground connection conductor is ensured.

特開2013−118121号公報JP 2013-118121 A

上述のような、平板状を成す絶縁基体に、各々が一体構造をとるものとされた、円筒形状を成す信号接続導体と信号接続導体を包囲する円筒形状を成す接地接続導体とが配され、信号接続導体に3個のスリットが設けられるとともに、接地接続導体に1個のスリットが設けられて構成された、従来の同軸コネクタ装置においては、それに他の同軸コネクタ装置が装着されるとき、円筒形状を成す信号接続導体が、その内側に挿入される他の同軸コネクタ装置の信号導体によって、3個のスリットの夫々の幅を広げるようにして外側に押し広げられ、また、円筒形状を成す接地接続導体が、その内側に挿入される他の同軸コネクタ装置の接地導体によって、1個のスリットの幅を広げるようにして外側に押し広げられるので、信号接続導体と接地接続導体との夫々が、内側からの外力を受けて変形を生じることになる。とりわけ、信号接続導体を包囲する接地接続導体にあっては、円筒形状における径が信号接続導体に比して大とされたもとで1個のスリットの幅を広げるものとされるので、その変形の度合いが比較的大とされる。   As described above, each of the insulating bases having a flat plate shape is provided with a cylindrical signal connection conductor and a cylindrical ground connection conductor surrounding the signal connection conductor, each of which has an integral structure, In the conventional coaxial connector device in which the signal connection conductor is provided with three slits and the ground connection conductor is provided with one slit, when another coaxial connector device is mounted on the signal connection conductor, A signal connection conductor having a shape is pushed outward by a signal conductor of another coaxial connector device inserted inside thereof so as to widen each of the three slits, and a grounding having a cylindrical shape. Since the connection conductor is pushed outward by widening the width of one slit by the ground conductor of another coaxial connector device inserted inside the connection conductor, it is in contact with the signal connection conductor. Each of the connecting conductors will result in a deformation by an external force from the inside. In particular, in the ground connection conductor that surrounds the signal connection conductor, the width of one slit is increased while the diameter of the cylindrical shape is larger than that of the signal connection conductor. The degree is relatively large.

それにより、従来の同軸コネクタ装置における接地接続導体は、それに他の同軸コネクタ装置が装着されるときにもたらされる変形に起因して、塑性変形を生じたものとなってしまう虞がある。特に、装置の小型化・偏平化がより一層図られて、信号接続導体及び接地接続導体についての円筒形状における仮想中心軸方向の寸法が低減される場合には、接地接続導体が塑性変形を生じたものとなる虞が増大することになってしまう。さらに、接地接続導体は、一体構造をとるもとで円筒形状を成して1個のスリットが設けられたものとされているので、その内側に挿入される他の同軸コネクタ装置の接地導体に対する接触圧や挿入抵抗力の設定・制御が、難しいことになるという不都合を伴っている。   As a result, the ground connection conductor in the conventional coaxial connector device may be plastically deformed due to deformation caused when another coaxial connector device is attached thereto. In particular, when the size and flattening of the device is further reduced and the dimensions of the signal connection conductor and the ground connection conductor in the cylindrical shape in the imaginary central axis direction are reduced, the ground connection conductor undergoes plastic deformation. There is an increased risk of becoming unintentional. Furthermore, since the ground connection conductor has a cylindrical shape and is provided with a single slit in an integrated structure, the ground connection conductor is connected to the ground conductor of another coaxial connector device inserted inside the ground connection conductor. Setting and control of contact pressure and insertion resistance is accompanied by the inconvenience.

斯かる点に鑑み、本願の特許請求の範囲に記載された発明は、絶縁基体に相手方コネクタにおける信号導体に係合接触する信号用接触部を有した信号接続導体と信号用接触部の周囲において相手方コネクタにおける接地導体に係合接触する接地用接触部を有した接地接続導体とが設けられて構成されたもとで、接地接続導体がその接地用接触部が係合接触する相手方コネクタにおける接地導体から受ける外力に起因して塑性変形を生じたものとなってしまう虞を抑制することができるとともに、接地接続導体についての相手方コネクタにおける接地導体に対する接触圧や挿入抵抗力の設定・制御を容易とすることができる同軸コネクタ装置を提供する。   In view of such a point, the invention described in the claims of the present application is based on the signal connection conductor having the signal contact portion engaged with the signal conductor in the mating connector on the insulating base and the periphery of the signal contact portion. And a ground connection conductor having a ground contact portion that engages and contacts the ground conductor in the mating connector, and the ground connection conductor is connected to the ground conductor in the mating connector that engages and contacts the ground contact portion. The risk of plastic deformation due to the external force received can be suppressed, and the setting and control of the contact pressure and insertion resistance force of the mating connector with respect to the grounding conductor can be facilitated. A coaxial connector device is provided.

上述のように構成される本願発明に係る同軸コネクタ装置は、信号接続導体と複数の接地接続導体とが相互絶縁状態をもって配された絶縁基体が、例えば、回路基板に配置されたもとにおいて、信号導体と接地導体とを備えた相手方コネクタとの嵌合接続がなされて使用される。絶縁基体が回路基板に配置されたもとにおいては、信号接続導体の信号用接続部が、外部信号端子とされる回路基板に設けられた信号端子に接続されるとともに、接地接続導体の接地用接続部が、外部接地端子とされる回路基板に設けられた接地端子に接続される。   In the coaxial connector device according to the present invention configured as described above, the signal conductor is formed on the circuit board, for example, when the insulating base in which the signal connection conductor and the plurality of ground connection conductors are arranged in a mutually insulated state. And a mating connector with a mating connector provided with a ground conductor.

そして、本願発明に係る同軸コネクタ装置が相手方コネクタとの嵌合接続状態におかれるときには、絶縁基体の中央突出部内に配された信号接続導体の信号用接触部が相手方コネクタにおける信号導体に係合接触するとともに、相手方コネクタにおける接地導体が、複数の接地接続導体が成す環状配列の内側に嵌合挿入されて複数の接地接続導体の夫々における接地用接触部に接触するものとされ、それにより、絶縁基体の外環部に配された複数の接地接続導体の夫々の接地用接触部が相手方コネクタにおける接地導体に係合接触することになる。その際、相手方コネクタにおける接地導体が複数の接地接続導体が成す環状配列の内側に嵌合挿入されて複数の接地接続導体の夫々における接地用接触部に接触する状態をとるとき、相手方コネクタにおける接地導体が、複数の接地接続導体の夫々における接地用接触部にそれを押圧する外力を及ぼし、接地用接触部に複数の接地接続導体が成す環状配列の外側に向かう変位を生じさせるが、斯かる接地用接触部の変位は、接地用接触部と接地用接続部とを連結する可動弾性屈曲部により吸収されて、接地接続導体の他の部分の不所望な変形をまねかないものとされる。   When the coaxial connector device according to the present invention is placed in a mating connection state with the mating connector, the signal contact portion of the signal connection conductor disposed in the central projecting portion of the insulating base is engaged with the signal conductor in the mating connector. In addition to contact, the ground conductor in the mating connector is fitted and inserted into the inside of the annular array formed by the plurality of ground connection conductors, and is in contact with the ground contact portion in each of the plurality of ground connection conductors. Each of the ground contact portions of the plurality of ground connection conductors arranged on the outer ring portion of the insulating base comes into engagement contact with the ground conductor in the mating connector. At that time, when the ground conductor in the mating connector is fitted and inserted into the inside of the annular array formed by the plurality of ground connection conductors and is brought into contact with the ground contact portion in each of the plurality of ground connection conductors, The conductor exerts an external force that presses the grounding contact portion of each of the plurality of ground connection conductors, and causes a displacement toward the outside of the annular array formed by the plurality of ground connection conductors in the ground contact portion. The displacement of the ground contact portion is absorbed by the movable elastic bending portion that connects the ground contact portion and the ground connection portion, and does not cause undesired deformation of other portions of the ground connection conductor.

また、本願発明に係る同軸コネクタ装置にあっては、所定の間隔をおいて絶縁基体の中央突出部を包囲して環状に配列されるものとして絶縁基体の外環部に配された複数の接地接続導体は、それらの各々の絶縁基体の外環部に対する位置を個別に調整する位置調整を行うことが可能とされていて、斯かる位置調整により、複数の接地接続導体についてのそれらが成す環状配列の内側に嵌合挿入されて接地用接触部に接触する相手方コネクタにおける接地導体に対する接触圧や挿入抵抗力の設定・制御を行うことができ、さらには、複数の接地接続導体が成す環状配列の径を変更することもできる。   Further, in the coaxial connector device according to the present invention, a plurality of grounds arranged on the outer ring portion of the insulating base as surrounding the central projecting portion of the insulating base at predetermined intervals and arranged in an annular shape The connection conductors can be individually adjusted in position with respect to the outer ring portion of each of the insulating bases.

First, as shown in FIG. In addition, a counterpart attached to a circuit board 26 (shown by imaginary lines in FIG. 6) different from the circuit board 25 at a position facing the coaxial connector device 10 attached to the circuit board 25. A connector 27 is disposed. The mating connector 27 is formed of an insulating material such as a synthetic resin material and has a cylindrical portion 29a (shown in FIG. 9 described later) made of a conductive material on an insulating base 28 disposed on the circuit board 26.

Thereafter, the mating connector 27 attached to the circuit board 26 is moved from the position shown in FIG. 6 toward the coaxial connector device 10 attached to the circuit board 25, and is fitted and connected to the coaxial connector device 10. As shown in FIGS. 7 (perspective view) and FIG. 8 (plan view), the mating connector 27 attached to the circuit board 26 is fitted and connected to the coaxial connector device 10 attached to the circuit board 25. It is done.

相手方コネクタ27が同軸コネクタ装置10に嵌合接続されたもとにあっては、図8におけるIX−IX線断面を示す図9に示されるように、相手方コネクタ27における信号導体29の円柱状部29aが、同軸コネクタ装置10における絶縁基体11の中央突出部14に形成された空洞16内に挿入され、同軸コネクタ装置10における空洞16に配された信号接続導体12の信号用接触部18が、それを形成する一対の相互対向弾性片によって信号導体29の円柱状部29aを挟持する。それにより、同軸コネクタ装置10における信号接続導体12の信号用接触部18が相手方コネクタ27における信号導体29に係合接触する状態が得られる。また、それとともに、相手方コネクタ27における接地導体30の環状部30aが、同軸コネクタ装置10における複数の接地接続導体13 が成す環状配列の内側に嵌合挿入されて、複数の接地接続導体13 の夫々における接地用接触部20に接触する。それにより、同軸コネクタ装置10における複数の接地接続導体13の夫々の接地用接触部20が相手方コネクタ27における接地導体30に係合接触する状態が得られる。   When the mating connector 27 is fitted and connected to the coaxial connector device 10, as shown in FIG. 9 showing a cross section taken along line IX-IX in FIG. 8, the columnar portion 29 a of the signal conductor 29 in the mating connector 27 is formed. The signal contact portion 18 of the signal connection conductor 12 inserted into the cavity 16 formed in the central projecting portion 14 of the insulating base 11 in the coaxial connector device 10 and disposed in the cavity 16 in the coaxial connector device 10 The cylindrical portion 29a of the signal conductor 29 is sandwiched by a pair of mutually opposing elastic pieces to be formed. As a result, a state is obtained in which the signal contact portion 18 of the signal connection conductor 12 in the coaxial connector device 10 engages and contacts the signal conductor 29 in the counterpart connector 27. At the same time, the annular portion 30a of the ground conductor 30 in the mating connector 27 is fitted and inserted inside the annular array formed by the plurality of ground connection conductors 13 in the coaxial connector device 10, so that each of the plurality of ground connection conductors 13 is provided. In contact with the contact portion 20 for grounding. As a result, a state is obtained in which each of the ground contact portions 20 of the plurality of ground connection conductors 13 in the coaxial connector device 10 engages and contacts the ground conductor 30 of the counterpart connector 27.

このようにして、相手方コネクタ27における接地導体30の環状部30aが、同軸コネクタ装置10における複数の接地接続導体13 が成す環状配列の内側に嵌合挿入されて、複数の接地接続導体13 の夫々における接地用接触部20に接触する際には、相手方コネクタ27における接地導体30の環状部30aが、同軸コネクタ装置10における複数の接地接続導体13 の夫々における接地用接触部20にそれを押圧する外力を及ぼし、その接地用接触部20に複数の接地接続導体13が成す環状配列の外側に向かう変位を生じさせるが、斯かる接地用接触部20の変位は、それに伴って当該接地接続導体13 における接地用接触部20と接地用接続部21とを連結する可動弾性屈曲部22が弾性変位することにより、可動弾性屈曲部22によって吸収される。即ち、同軸コネクタ装置10における複数の接地接続導体13 の夫々の接地用接触部20に、それに接触する相手方コネクタ27における接地導体30の環状部30aによってもたらされる変位は、当該接地接続導体13 の可動弾性屈曲部22により吸収されて、接地接続導体13の他の部分の不所望な変形をまねかないものとされるのである。   In this manner, the annular portion 30a of the ground conductor 30 in the mating connector 27 is fitted and inserted inside the annular array formed by the plurality of ground connection conductors 13 in the coaxial connector device 10, and each of the plurality of ground connection conductors 13 is inserted. In contact with the ground contact portion 20, the annular portion 30 a of the ground conductor 30 in the mating connector 27 presses it against the ground contact portion 20 in each of the plurality of ground connection conductors 13 in the coaxial connector device 10. An external force is applied, and the ground contact portion 20 is displaced toward the outside of the annular array formed by the plurality of ground connection conductors 13. The displacement of the ground contact portion 20 is accompanied by the displacement of the ground connection conductor 13. When the movable elastic bending portion 22 that connects the ground contact portion 20 and the ground connection portion 21 is elastically displaced, the movable elastic bending portion 22 is moved. Thus it is absorbed. That is, the displacement caused by the annular portion 30a of the ground conductor 30 in the mating connector 27 that contacts each ground contact portion 20 of the plurality of ground connection conductors 13 in the coaxial connector device 10 is movable. It is absorbed by the elastic bent portion 22 and does not cause undesired deformation of other portions of the ground connection conductor 13.

なお、相手方コネクタ27における接地導体30の環状部30aが、同軸コネクタ装置10における複数の接地接続導体13 の夫々の接地用接触部20に接触する際には、図9に示されるように、接地用接触部20に設けられた接触突起20aが接地導体30の環状部30aに設けられた凹部に係合して、複数の接地接続導体13 の夫々の接地用接触部20に接触した接地導体30の環状部30aを係止する。それにより、相手方コネクタ27における接地導体30の環状部30aが同軸コネクタ装置10における複数の接地接続導体13 の夫々の接地用接触部20に接触した状態が安定に維持される。   When the annular portion 30a of the ground conductor 30 in the mating connector 27 contacts each of the ground contact portions 20 of the plurality of ground connection conductors 13 in the coaxial connector device 10, as shown in FIG. The contact protrusion 20a provided on the contact portion 20 engages with the recess provided on the annular portion 30a of the ground conductor 30 to contact the ground contact portion 20 of each of the plurality of ground connection conductors 13. The annular portion 30a is locked. Thus, the state in which the annular portion 30a of the ground conductor 30 in the mating connector 27 is in contact with the ground contact portions 20 of the plurality of ground connection conductors 13 in the coaxial connector device 10 is stably maintained.

そして、回路基板26に取り付けられた相手方コネクタ27が回路基板25に取り付けられた同軸コネクタ装置10に嵌合接続されたもとにあっては、同軸コネクタ装置10が取り付けられた回路基板25と相手方コネクタ27が取り付けられた回路基板26とが、同軸コネクタ装置10における信号接続導体12及び複数の接地接続導体13及び相手方コネクタ27における信号導体29及び接地導体30を通じて、電気的に接続されることになり、伝送にあたって電磁波シールドが必要とされる信号の回路基板25と回路基板26との間での伝送が可能とされる。   Then, when the counterpart connector 27 attached to the circuit board 26 is fitted and connected to the coaxial connector device 10 attached to the circuit board 25, the circuit board 25 to which the coaxial connector device 10 is attached and the counterpart connector 27 are connected.

上述の同軸コネクタ装置10によれば、相手方コネクタ27との嵌合接続状態におかれるにあたり、相手方コネクタ27における接地導体30の環状部30aが、複数の接地接続導体13が成す環状配列の内側に嵌合挿入されて複数の接地接続導体13の夫々における接地用接触部20に接触するものとされ、それにより、絶縁基体11の外環部15に配された複数の接地接続導体13の夫々の接地用接続部20が相手方コネクタ27における接地導体30に係合接触することになる際に、相手方コネクタ27における接地導体30が、複数の接地接続導体13の夫々における接地用接触部20に、それを押圧する外力を及ぼして生じさせる複数の接地接続導体13が成す環状配列の外側に向かう変位が、接地用接触部20と接地用接続部21とを連結する可動弾性屈曲部22により吸収されて、接地接続導体13の他の部分の不所望な変形をまねかないものとされるので、複数の接地接続導体13の夫々がその接地用接触部20が係合接触する相手方コネクタ27における接地導体30から受ける外力に起因して塑性変形を生じたものとなってしまう虞を抑制することができる。   According to the above-described coaxial connector device 10, the annular portion 30 a of the ground conductor 30 in the mating connector 27 is placed inside the annular array formed by the plurality of ground connection conductors 13 when the mating connector 27 is fitted and connected.

The displacement toward the outside of the annular array formed by the plurality of ground connection conductors 13 generated by applying an external force that presses the ground contact portion 20 and the ground connection portion 2 Are absorbed by the movable elastic bending portion 22 that couples the two, the ground connection conductor 13 is not undesirably deformed, so that each of the ground connection conductors 13 is connected to the ground contact portion. It is possible to suppress the possibility of plastic deformation due to an external force received from the ground conductor 30 in the mating connector 27 with which the connector 20 is engaged and contacted.

また、同軸コネクタ装置10にあっては、所定の間隔をおいて絶縁基体11の中央突出部14を包囲して環状に配列されるものとして絶縁基体11の外環部15に配された複数の接地接続導体13が、それらの各々の絶縁基体11の外環部15に対する位置を個別に調整する位置調整を行うことが可能とされていて、それにより、複数の接地接続導体13についてのそれらが成す環状配列の内側に嵌合挿入されて接地用接触部20に接触する相手方コネクタ27における接地導体30に対する接触圧や挿入抵抗力の設定・制御を行うことができ、さらには、複数の接地接続導体13が成す環状配列の径を変更することもできるので、複数の接地接続導体13の夫々についての相手方コネクタ27における接地導体30に対する接触圧や挿入抵抗力の設定・制御を容易とすることができる。   Further, in the coaxial connector device 10, a plurality of elements disposed on the outer ring portion 15 of the insulating base 11 are arranged so as to surround the central projecting portion 14 of the insulating base 11 with a predetermined interval. The position of the ground connection conductor 13 can be adjusted by individually adjusting the position of each of the insulating bases 11 with respect to the outer ring portion 15. It is possible to set and control the contact pressure and the insertion resistance force with respect to the ground conductor 30 in the mating connector 27 that is fitted and inserted into the annular arrangement formed to come into contact with the ground contact portion 20, and moreover, a plurality of ground connections Since the diameter of the annular array formed by the conductors 13 can also be changed, the contact pressure or insertion resistance of the ground connector 30 in the mating connector 27 for each of the plurality of ground connection conductors 13 can be changed.
