Description

本願の特許請求の範囲に記載された発明は、中心導体とそれを内部絶縁体を介して包囲する外側導体とが外部絶縁体により被覆されて成る同軸ケーブルの中心導体及び外側導体が夫々接続される、互いに絶縁されたコンタクト部材及びグラウンドコンタクト部材を備えて成り、他のコネクタ装置である相手方コネクタ装置に機械的かつ電気的に連結される同軸コネクタ装置に関する。   In the invention described in the claims of the present application, the center conductor and the outer conductor of the coaxial cable in which the center conductor and the outer conductor surrounding the center conductor are covered with the outer insulator are connected to each other. The present invention relates to a coaxial connector device that includes a contact member and a ground contact member that are insulated from each other and is mechanically and electrically connected to a mating connector device that is another connector device.

複数の電気部品，電気装置あるいは電子機器間等における高周波信号の伝送には、外部ノイズの影響を受けにくい信号伝送路を形成する、中心導体とそれを内部絶縁体を介して包囲する外部導体とが外部絶縁体により被覆されて成る同軸ケーブルが用いられることが多い。例えば、同軸ケーブルが高周波信号を扱う回路基板に接続されて、当該回路基板からその外部への同軸ケーブルを通じた高周波信号の伝送、あるいは、当該回路基板への外部からの高周波信号の同軸ケーブルを通じた伝送が行われる。   For transmission of high-frequency signals between multiple electrical components, electrical devices, or electronic devices, a central conductor and an outer conductor that surrounds it through an internal insulator, forming a signal transmission path that is not easily affected by external noise. In many cases, coaxial cables are used that are covered with an external insulator. For example, when a coaxial cable is connected to a circuit board that handles high-frequency signals, the high-frequency signal is transmitted from the circuit board to the outside through the coaxial cable, or from the outside to the circuit board through the coaxial cable of the high-frequency signal. Transmission takes place.

同軸ケーブルが回路基板に接続される際には、同軸ケーブルの中心導体が接続されるコンタクト部材と同軸ケーブルの外部導体が接続されるグラウンドコンタクト部材とを備えた同軸コネクタ装置が同軸ケーブルの一端に装着され、その同軸コネクタ装置が、例えば、回路基板において扱われる高周波信号が供給される中心コンタクトと中心コンタクトを包囲して配されてグラウンド電位が与えられる環状グラウンドコンタクトを備えて回路基板に取り付けられた相手方コネクタ装置に機械的かつ電気的に連結される。このような同軸コネクタ装置が相手方コネクタ装置に機械的かつ電気的に連結される状態は、例えば、同軸コネクタ装置のグラウンドコンタクト部材が相手方コネクタ装置の環状グラウンドコンタクトに嵌合接続されるもとで、同軸コネクタ装置のコンタクト部材が相手方コネクタ装置の中心コンタクトに接触接続されることによりとられる。   When the coaxial cable is connected to the circuit board, a coaxial connector device having a contact member to which the central conductor of the coaxial cable is connected and a ground contact member to which the outer conductor of the coaxial cable is connected is connected to one end of the coaxial cable. The coaxial connector device is attached to the circuit board, for example, provided with a center contact to which a high-frequency signal to be handled in the circuit board is supplied and an annular ground contact which is arranged to surround the center contact and to which a ground potential is applied. Mechanically and electrically connected to the mating connector device. The state in which such a coaxial connector device is mechanically and electrically coupled to the counterpart connector device is, for example, that the ground contact member of the coaxial connector device is fitted and connected to the annular ground contact of the counterpart connector device. The contact member of the coaxial connector device is contacted and connected to the center contact of the counterpart connector device.

斯かる同軸コネクタ装置の相手方コネクタ装置との機械的かつ電気的な連結が行われるにあたっては、回路基板に取り付けられた相手方コネクタ装置が、例えば、それにおける中心コンタクトと環状グラウンドコンタクトとを回路基板における部品等搭載面の上方に向かわせるものとされ、その相手方コネクタ装置に対して、同軸ケーブルの一端に装着された同軸コネクタ装置が、回路基板における部品等搭載面の上方からその部品等搭載面に向かう方向をもって係合せしめられて、同軸コネクタ装置のグラウンドコンタクト部材が相手方コネクタ装置の環状グラウンドコンタクトに嵌合接続されるとともに、同軸コネクタ装置のコンタクト部材が相手方コネクタ装置の中心コンタクトに接触接続される。従って、相手方コネクタ装置が取り付けられた回路基板上において、同軸コネクタ装置は、回路基板における部品等搭載面から突出するものとなる。   When mechanical and electrical connection of the coaxial connector device to the counterpart connector device is performed, the counterpart connector device attached to the circuit board has, for example, a center contact and an annular ground contact in the circuit board. The coaxial connector device attached to one end of the coaxial cable is directed from above the component mounting surface on the circuit board to the component mounting surface. The ground contact member of the coaxial connector device is engaged and connected to the annular ground contact of the counterpart connector device, and the contact member of the coaxial connector device is contact-connected to the center contact of the counterpart connector device. . Therefore, on the circuit board to which the counterpart connector apparatus is attached, the coaxial connector apparatus protrudes from the mounting surface of the parts and the like on the circuit board.

上述のようにして、同軸コネクタ装置が相手方コネクタ装置に機械的かつ電気的に連結されたもとにあっては、同軸コネクタ装置の相手方コネクタ装置との機械的かつ電気的な連結が不所望に解除されてしまう事態の発生が回避されることが望まれる。そのため、従来においては、同軸コネクタ装置とそれが機械的かつ電気的に連結される相手方コネクタ装置とに、同軸コネクタ装置の相手方コネクタ装置との機械的かつ電気的な連結をその不所望な解除を回避すべく維持するためのロック機構（係止機構）を設けることが提案されている（例えば、特許文献１参照。）。   As described above, when the coaxial connector device is mechanically and electrically connected to the counterpart connector device, the mechanical and electrical connection of the coaxial connector device with the counterpart connector device is undesirably released. It is hoped that the occurrence of the situation will be avoided. Therefore, in the related art, the mechanical and electrical connection between the coaxial connector device and the counterpart connector device to which the coaxial connector device is mechanically and electrically connected is undesirably released. It has been proposed to provide a lock mechanism (locking mechanism) for maintaining to avoid (see, for example, Patent Document 1).

特許文献１に開示されている同軸コネクタ装置（同軸コネクタ(10)) 及びそれが機械的かつ電気的に連結される相手方コネクタ装置（相手コネクタ(60)) にあっては、同軸コネクタ装置が、同軸ケーブル（ケーブル(C))の中心導体（芯線(C1)) との接続がなされるコンタクト部材（端子(13)) と同軸ケーブルの外側導体（シールド線(C2)) との接続がなされるグラウンドコンタクト部材（外部導体(11)) とが、絶縁ハウジング部材（誘電体(12)) によって相互絶縁状態をもって保持されて構成されたものとされ、また、相手方コネクタ装置が、回路基板における信号端子部に接続されたシグナルコンタクト部（中心導体(62)) とシグナルコンタクト部の接触接続部（接触部(62A))を包囲するグラウンドコンタクト部（外部導体(61)) とが、絶縁ハウジング部材（誘電体(63)) によって相互絶縁状態をもって保持されて構成されたものとされる。そして、同軸コネクタ装置が相手方コネクタ装置に機械的かつ電気的に連結される際には、同軸コネクタ装置のグラウンドコンタクト部材における嵌合筒状部(14)が相手方コネクタ装置のグラウンドコンタクト部に嵌合接続されるとともに、同軸コネクタ装置のコンタクト部材における接触部(25)が相手方コネクタ装置のシグナルコンタクト部における接触接続部に接触接続される。   In the coaxial connector device (coaxial connector (10)) disclosed in Patent Document 1 and the mating connector device (mating connector (60)) to which it is mechanically and electrically connected, the coaxial connector device includes: The contact member (terminal (13)) that is connected to the central conductor (core wire (C1)) of the coaxial cable (cable (C)) is connected to the outer conductor (shield wire (C2)) of the coaxial cable. The ground contact member (external conductor (11)) is held by the insulating housing member (dielectric (12)) in a mutually insulated state, and the mating connector device is connected to the signal terminal on the circuit board. The signal contact portion (center conductor (62)) connected to the contact portion and the ground contact portion (outer conductor (61)) surrounding the contact connection portion (contact portion (62A)) of the signal contact portion are insulated housing members ( dielectric The body (63)) is held in a mutually insulated state. When the coaxial connector device is mechanically and electrically connected to the mating connector device, the fitting cylindrical portion (14) in the ground contact member of the coaxial connector device is fitted into the ground contact portion of the mating connector device. In addition to being connected, the contact portion (25) in the contact member of the coaxial connector device is contact-connected to the contact connection portion in the signal contact portion of the counterpart connector device.

斯かるもとで、同軸コネクタ装置のグラウンドコンタクト部材における嵌合筒状部は、金属板が湾曲せしめられて環状を成すものとして形成されていて、その内面部に周方向に延びる略環状の突条部(14B) がロック部を成すものとして設けられたものとされており、また、相手方コネクタ装置のグラウンドコンタクト部は、円筒状を成していて、その外面部に環状のロック溝(61A) が形成されたものとされている。斯かるもとで、同軸コネクタ装置のグラウンドコンタクト部材における嵌合筒状部の内面部に設けられた突条部(14B) の内径寸法が、その外面部にロック溝(61A) が形成された相手方コネクタ装置のグラウンドコンタクト部の外径寸法より小となるように設定されている。   Under such circumstances, the fitting cylindrical portion of the ground contact member of the coaxial connector device is formed as a ring formed by bending the metal plate, and a substantially annular protrusion extending in the circumferential direction on the inner surface thereof. The strip portion (14B) is provided as a lock portion, and the ground contact portion of the mating connector device has a cylindrical shape, and an annular lock groove (61A) is formed on the outer surface portion thereof. ) Has been formed. Under such circumstances, the inner diameter of the protrusion (14B) provided on the inner surface of the fitting cylindrical portion of the ground contact member of the coaxial connector device is the same as that of the outer surface, and the lock groove (61A) is formed. It is set to be smaller than the outer diameter of the ground contact portion of the mating connector device.

そして、同軸コネクタ装置が相手方コネクタ装置に機械的かつ電気的に連結されるにあたり、同軸コネクタ装置のグラウンドコンタクト部材における嵌合筒状部が相手方コネクタ装置のグラウンドコンタクト部に嵌合接続されたときには、同軸コネクタ装置のグラウンドコンタクト部材における嵌合筒状の内面に設けられた突条部(14B) が、相手方コネクタ装置のグラウンドコンタクト部の外面部に形成されたロック溝(61A) に係合し、それにより、同軸コネクタ装置のグラウンドコンタクト部材における嵌合筒状部の相手方コネクタ装置のグラウンドコンタクト部に対する嵌合が不所望に解除される事態が阻止されるようになされている。   And, when the coaxial connector device is mechanically and electrically connected to the counterpart connector device, when the fitting cylindrical portion of the ground contact member of the coaxial connector device is fitted and connected to the ground contact portion of the counterpart connector device, The protrusion (14B) provided on the inner surface of the fitting cylindrical shape in the ground contact member of the coaxial connector device engages with the lock groove (61A) formed in the outer surface portion of the ground contact portion of the counterpart connector device, Thereby, the situation where the fitting of the fitting cylindrical portion of the ground contact member of the coaxial connector device to the ground contact portion of the mating connector device is undesirably released is prevented.

突条部(14B) がロック溝(61A) に係合する際には、先ず、同軸コネクタ装置のグラウンドコンタクト部材が具える弾性が生かされたもとで、グラウンドコンタクト部材における嵌合筒状部が一時的に拡大変形せしめられて当該嵌合筒状部の内面部に設けられた略環状の突条部(14B) の内径寸法が一時的に拡大されて、突条部(14B) が相手方コネクタ装置のグラウンドコンタクト部の外面部に当接する状態がとられる。続いて、突条部(14B) が相手方コネクタ装置のグラウンドコンタクト部の外面部に沿って移動せしめられて当該外面部に形成されたロック溝(61A) に係合し、それにより、一時的に拡大された突条部(14B) の内径寸法が元に戻される状態がとられる。   When the protrusion (14B) engages with the lock groove (61A), first, the elasticity of the ground contact member of the coaxial connector device is utilized, and the fitting cylindrical portion of the ground contact member temporarily moves. The inner diameter of the substantially annular ridge (14B) provided on the inner surface of the fitting cylindrical portion is temporarily enlarged, and the ridge (14B) is temporarily connected to the mating connector device. The state of contacting the outer surface portion of the ground contact portion is taken. Subsequently, the protrusion (14B) is moved along the outer surface portion of the ground contact portion of the mating connector device to engage with the lock groove (61A) formed in the outer surface portion, thereby temporarily A state is taken in which the inner diameter dimension of the enlarged protrusion (14B) is restored.

このようなもとで、同軸コネクタ装置のグラウンドコンタクト部材における嵌合筒状部の内面部に設けられた突条部(14B) と相手方コネクタ装置のグラウンドコンタクト部の外面部に形成されたロック溝(61A) とは、同軸コネクタ装置のグラウンドコンタクト部材における嵌合筒状部の相手方コネクタ装置のグラウンドコンタクト部に対する嵌合が不所望に解除される事態を阻止して、同軸コネクタ装置の相手方コネクタ装置との機械的かつ電気的な連結をその不所望な解除を回避すべく維持するためのロック機構を構成していることになる。   Under such circumstances, the protrusion (14B) provided on the inner surface portion of the fitting cylindrical portion of the ground contact member of the coaxial connector device and the lock groove formed on the outer surface portion of the ground contact portion of the mating connector device. (61A) is to prevent a situation in which the fitting of the fitting cylindrical portion of the ground contact member of the coaxial connector device to the ground contact portion of the counterpart connector device is undesirably released, and the counterpart connector device of the coaxial connector device The lock mechanism is configured to maintain the mechanical and electrical connection with the main body so as to avoid undesired release thereof.

上述の従来提案されている同軸コネクタ装置及びそれが機械的かつ電気的に連結される相手方コネクタ装置においては、同軸コネクタ装置のグラウンドコンタクト部材における嵌合筒状部の内面部にロック部を成す略環状の突条部(14B) が設けられるとともに、相手方コネクタ装置の円筒状を成すグラウンドコンタクト部の外面部に環状のロック溝(61A) が形成され、略環状の突条部(14B) の内径寸法が、ロック溝(61A) が形成された外面部を有する円筒状を成すグラウンドコンタクト部の外径寸法より小となるように設定されたもとで、同軸コネクタ装置が相手方コネクタ装置に機械的かつ電気的に連結されるときには、同軸コネクタ装置のグラウンドコンタクト部材における嵌合筒状部が、一時的に拡大変形せしめられつつ相手方コネクタ装置のグラウンドコンタクト部に嵌合接続され、突条部(14B) がロック溝(61A) に係合する状態がとられるが、その際に、次のような突条部(14B) の内径寸法の選定に伴う不都合がもたらされる。   In the above-described conventionally proposed coaxial connector device and the mating connector device to which it is mechanically and electrically connected, a lock portion is formed on the inner surface of the fitting cylindrical portion of the ground contact member of the coaxial connector device. An annular protrusion (14B) is provided, and an annular lock groove (61A) is formed on the outer surface of the cylindrical ground contact portion of the mating connector device, and the inner diameter of the substantially annular protrusion (14B) The coaxial connector device is mechanically and electrically connected to the mating connector device when the size is set to be smaller than the outer diameter size of the cylindrical ground contact portion having the outer surface portion where the lock groove (61A) is formed. Are connected to each other, the fitting cylindrical portion of the ground contact member of the coaxial connector device is temporarily expanded and deformed while the counterpart connector device When the ridge (14B) is engaged with the round contact and engaged with the lock groove (61A), select the inner diameter of the ridge (14B) as shown below. The inconvenience associated with is brought about.

即ち、突条部(14B) の内径寸法がそれより大とされるグラウンドコンタクト部の外径寸法との差が比較的大となるように選定されたときには、内面部に突条部(14B) が設けられた同軸コネクタ装置のグラウンドコンタクト部材における嵌合筒状部を、一時的に拡大変形させつつその内面部に設けられた突条部(14B) を相手方コネクタ装置のグラウンドコンタクト部の外面部に当接させて当該グラウンドコンタクト部に嵌合させ、その後、突条部(14B) を相手方コネクタ装置のグラウンドコンタクト部の外面部に形成されたロック溝(61A) に係合させるにあたり、当該嵌合筒状部に対する相当に大なる操作力が要されることになるという不都合を招き、また、逆に、突条部(14B) の内径寸法がそれより大とされるグラウンドコンタクト部の外径寸法との差が比較的小となるように選定されたときには、同軸コネクタ装置のグラウンドコンタクト部材における嵌合筒状部が相手方コネクタ装置のグラウンドコンタクト部に嵌合接続されたもとでの、突条部(14B) のロック溝(61A) との係合が緩やかなものとされて、同軸コネクタ装置のグラウンドコンタクト部材における嵌合筒状部が、不所望に一時的な拡大変形を生じて相手方コネクタ装置のグラウンドコンタクト部に対する嵌合を解除してしまう状態が生じ易いことになるという不都合を招くことになる。   That is, when the inner diameter of the protrusion (14B) is selected so that the difference from the outer diameter of the ground contact portion that is larger than that is relatively large, the protrusion (14B) The protruding cylindrical portion (14B) provided on the inner surface of the fitting cylindrical portion of the ground contact member of the coaxial connector device provided with the outer surface portion of the mating connector device is temporarily expanded and deformed. In contact with the ground contact portion and then engaging the protrusion (14B) with the lock groove (61A) formed in the outer surface portion of the ground contact portion of the mating connector device. This causes the inconvenience that a considerably large operating force is required for the combined cylindrical part, and conversely, the outer diameter of the ground contact part in which the inner diameter of the protrusion (14B) is larger than that. The difference from the dimension is When selected to be relatively small, the locking of the protruding portion (14B) with the fitting cylindrical portion of the ground contact member of the coaxial connector device being fitted and connected to the ground contact portion of the mating connector device The engagement with the groove (61A) is made loose, and the fitting cylindrical portion of the ground contact member of the coaxial connector device undesirably temporarily expands and deforms relative to the ground contact portion of the counterpart connector device. This causes a disadvantage that a state where the fitting is released is likely to occur.

そして、コネクタ本体が、それにおけるグラウンドコンタクト部材が、相手方コネクタ装置のグラウンドコンタクト部に嵌合接続される環状嵌合部とそれから屈曲可能に伸びてコンタクト部材との接続がなされた中心導体を有した同軸ケーブルの外側導体との接続がなされるシェル部とを有し、環状嵌合部が、その仮想中心軸方向に沿う方向に延びるスリットが形成されるとともに、その内面部に、環状嵌合部が嵌合接続される相手方コネクタ装置のグラウンドコンタクト部における外面部に設けられた被係合部に係合する係合部が設けられたものとされる。また、係止部材が、コネクタ本体におけるグラウンドコンタクト部材の環状嵌合部における外周面部に着脱可能に係合せしめられるものとされ、斯かる係止部材には、グラウンドコンタクト部材の環状嵌合部における外周面部に係合せしめられたとき当該外周面部の周囲を廻る移動が可能とされて配される係止係合部が設けられていて、係止係合部は、グラウンドコンタクト部材の環状嵌合部をそれに形成されたスリットを部分的に塞ぐ位置をもって外側から係止して、当該環状嵌合部についてのそれに形成されたスリットを拡幅させる変形を規制する役割を果たす。   The connector main body has an annular fitting portion in which the ground contact member is fitted and connected to the ground contact portion of the mating connector device, and a center conductor that is bent and extends from the center conductor and connected to the contact member. A shell portion that is connected to the outer conductor of the coaxial cable, and the annular fitting portion is formed with a slit extending in the direction along the virtual central axis direction, and the annular fitting portion is formed on the inner surface portion thereof. Is provided with an engaging portion that engages with an engaged portion provided on an outer surface portion of the ground contact portion of the mating connector device to which the connector connector is fitted and connected. In addition, the locking member is detachably engaged with the outer peripheral surface portion of the annular fitting portion of the ground contact member in the connector main body, and such a locking member is provided in the annular fitting portion of the ground contact member. A locking engagement portion is provided that is arranged so as to be able to move around the outer peripheral surface portion when engaged with the outer peripheral surface portion, and the locking engagement portion is an annular fitting of the ground contact member The part is locked from the outside at a position where the slit formed in the part is partially closed, and the role of expanding the slit formed in the annular fitting part is regulated.

このようなもとで、グラウンドコンタクト部材の環状嵌合部が相手方コネクタ装置のグラウンドコンタクト部に嵌合接続されたとき、環状嵌合部における内面部に設けられた係合部が、相手方コネクタ装置のグラウンドコンタクト部における外面部に設けられた被係合部に係合する。そして、例えば、グラウンドコンタクト部材の環状嵌合部が相手方コネクタ装置のグラウンドコンタクト部に嵌合接続されて、環状嵌合部における内面部に設けられた係合部が相手方コネクタ装置のグラウンドコンタクト部における外面部に設けられた被係合部に係合し、グラウンドコンタクト部材のシェル部が環状嵌合部に対して屈曲せしめられたもとで、係止部材が、グラウンドコンタクト部材の環状嵌合部における外周面部に係合せしめられ、係止部材に設けられた係止係合部が、環状嵌合部の外側において当該環状嵌合部に形成されたスリットを部分的に塞ぐ位置をとるものとされる。   Under such circumstances, when the annular fitting portion of the ground contact member is fitted and connected to the ground contact portion of the counterpart connector device, the engaging portion provided on the inner surface portion of the annular fitting portion is the counterpart connector device. It engages with the engaged portion provided on the outer surface portion of the ground contact portion. For example, the annular fitting portion of the ground contact member is fitted and connected to the ground contact portion of the counterpart connector device, and the engaging portion provided on the inner surface portion of the annular fitting portion is the ground contact portion of the counterpart connector device. The engaging member is engaged with the engaged portion provided on the outer surface portion, and the outer peripheral portion of the ground contact member in the annular fitting portion is bent with the shell portion of the ground contact member bent with respect to the annular fitting portion. The locking engagement portion that is engaged with the surface portion and is provided on the locking member takes a position that partially closes the slit formed in the annular fitting portion outside the annular fitting portion. .

上述のようにして、グラウンドコンタクト部材の環状嵌合部の外側において当該環状嵌合部に形成されたスリットを部分的に塞ぐ位置をとるものとされた係止部材の係止係合部は、相手方コネクタ装置のグラウンドコンタクト部における外面部に設けられた被係合部に係合した係合部を内面部に設けられたものとして伴った環状嵌合部に、相手方コネクタ装置のグラウンドコンタクト部との嵌合接続状態を解除させてグラウンドコンタクト部から離隔させようとする不所望な外力が作用するとき、環状嵌合部をその外側から係止して、当該環状嵌合部についてのそれに形成されたスリットを拡幅させる外方への拡大変形を規制する。環状嵌合部は、相手方コネクタ装置のグラウンドコンタクト部との嵌合接続状態を解除してグラウンドコンタクト部から離隔するときには、その内面部に設けられて相手方コネクタ装置のグラウンドコンタクト部における外面部に設けられた被係合部に係合した係合部を被係合部から外すべく、それに形成されたスリットを拡幅させる外方への拡大変形を生じることが必要とされるが、斯かる拡大変形が係止部材に設けられた係止係合部によって規制されることにより、環状嵌合部が、その内面部に設けられた係合部が相手方コネクタ装置のグラウンドコンタクト部の外面部に設けられた被係合部に係合した状態を継続するものとされる。   As described above, the locking engagement portion of the locking member that takes the position of partially closing the slit formed in the annular fitting portion outside the annular fitting portion of the ground contact member, The ground contact portion of the counterpart connector device is connected to the annular fitting portion that is engaged with the engaged portion provided on the outer surface portion of the ground contact portion of the counterpart connector device as provided on the inner surface portion. When an undesired external force is applied to release the fitting connection state of the ring contact portion and separate from the ground contact portion, the annular fitting portion is locked from the outside and formed on the annular fitting portion. Regulates outward expansion deformation that widens the slit. The annular fitting portion is provided on the inner surface portion of the mating connector device when the mating connection state with the ground contact portion of the counterpart connector device is released and separated from the ground contact portion, and is provided on the outer surface portion of the ground contact portion of the counterpart connector device. In order to disengage the engaging part engaged with the engaged part from the engaged part, it is necessary to generate an outward expansion deformation that widens the slit formed therein. Is controlled by the locking engagement portion provided on the locking member, and the engagement portion provided on the inner surface portion of the annular fitting portion is provided on the outer surface portion of the ground contact portion of the counterpart connector device. The state engaged with the engaged portion is continued.

従って、グラウンドコンタクト部材の環状嵌合部は、それに相手方コネクタ装置のグラウンドコンタクト部との嵌合接続状態を解除させてグラウンドコンタクト部から離隔させようとする不所望な外力が作用するときにおいても、その内面部に設けられた係合部が相手方コネクタ装置のグラウンドコンタクト部における外面部に設けられた被係合部に係合した状態を継続するものとされて、相手方コネクタ装置のグラウンドコンタクト部との嵌合接続状態を維持することになる。   Therefore, even when an undesired external force is applied to the annular fitting portion of the ground contact member to release the fitting connection state with the ground contact portion of the mating connector device and to separate it from the ground contact portion, The engagement portion provided on the inner surface portion continues to be engaged with the engaged portion provided on the outer surface portion of the ground contact portion of the counterpart connector device, and the ground contact portion of the counterpart connector device and The fitting connection state is maintained.

グラウンドコンタクト部材の環状嵌合部の相手方コネクタ装置のグラウンドコンタクト部との嵌合接続状態が意図的に解除されるときには、環状嵌合部が相手方コネクタ装置のグラウンドコンタクト部との嵌合接続状態におかれたもとで、例えば、係止部材の環状嵌合部における外周面部との係合が解除されて環状嵌合部から取り外された後、環状嵌合部にそれを相手方コネクタ装置のグラウンドコンタクト部から離隔させるための適切な外力が作用せしめられる。それにより、環状嵌合部が、それに形成されたスリットを拡幅させる外方への拡大変形を一時的に生じ、その内面部に設けられた係合部を相手方コネクタ装置のグラウンドコンタクト部における外面部に設けられた被係合部から外れるものとして、相手方コネクタ装置のグラウンドコンタクト部との嵌合接続状態を解除する。   When the mating connection state of the annular fitting portion of the ground contact member with the ground contact portion of the mating connector device is intentionally released, the annular fitting portion enters the mating connection state with the ground contact portion of the mating connector device. For example, after the engagement with the outer peripheral surface portion of the annular fitting portion of the locking member is released and removed from the annular fitting portion, the ground contact portion of the counterpart connector device is connected to the annular fitting portion. Appropriate external force is applied to separate from. Thereby, the annular fitting portion temporarily causes outward expansion deformation to widen the slit formed therein, and the engaging portion provided on the inner surface portion is the outer surface portion in the ground contact portion of the counterpart connector device. The mating connection state with the ground contact part of the mating connector device is released as a part that is disengaged from the engaged part provided in the connector.

このような本願発明に係る同軸コネクタ装置にあっては、回路基板に装着された相手方コネクタ装置に機械的かつ電気的に連結されるにあたり、コネクタ本体におけるグラウンドコンタクト部材の環状嵌合部が相手方コネクタ装置のグラウンドコンタクト部に嵌合接続されて、コネクタ本体と別体に形成された係止部材が環状嵌合部における外周面部に係合せしめられ、係止部材に設けられた係止係合部が環状嵌合部の外側において当該環状嵌合部に形成されたスリットを部分的に塞ぐ位置をとるものとされることにより、相手方コネクタ装置のグラウンドコンタクト部に嵌合接続された環状嵌合部に、相手方コネクタ装置のグラウンドコンタクト部との嵌合接続状態を解除させてグラウンドコンタクト部から離隔させようとする不所望な外力が作用しても、環状嵌合部における外周面部に係合せしめられた係止部材に設けられた係止係合部が、環状嵌合部についてのそれに形成されたスリットを拡幅させる外方への拡大変形を規制するので、それにより、環状嵌合部に相手方コネクタ装置のグラウンドコンタクト部との嵌合接続状態を維持させることができる。その結果、同軸コネクタ装置の相手方コネクタ装置との機械的かつ電気的な連結が、その不所望な解除が回避されて、確実に維持されることになる。   In such a coaxial connector device according to the present invention, when mechanically and electrically connected to the mating connector device mounted on the circuit board, the annular fitting portion of the ground contact member in the connector body is the mating connector. A locking engagement portion provided on the locking member is engaged with and connected to the ground contact portion of the apparatus, and a locking member formed separately from the connector main body is engaged with the outer peripheral surface portion of the annular fitting portion. An annular fitting portion that is fitted and connected to the ground contact portion of the mating connector device by taking a position that partially closes the slit formed in the annular fitting portion outside the annular fitting portion. In the mating connection with the ground contact portion of the mating connector device, and undesirably Even if the action is applied, the locking engagement portion provided on the locking member engaged with the outer peripheral surface portion of the annular fitting portion outwardly widens the slit formed in the annular fitting portion. Therefore, the annular fitting portion can maintain the fitting connection state with the ground contact portion of the mating connector device. As a result, the mechanical and electrical connection of the coaxial connector device with the counterpart connector device can be reliably maintained while avoiding undesired release.

斯かるもとで、係止係合部が設けられた係止部材が、例えば、屈曲加工された板材あるいは切削加工が施された金属材料によって一体に形成されて、グラウンドコンタクト部材における環状嵌合部の外周面部に着脱可能に係合せしめられるものとされ、係止部材における係止係合部が、係止部材が環状嵌合部における外周面部に係合せしめられたとき当該外周面部の周囲を廻る移動が可能とされて配される構成は、比較的簡単な構成とされる。また、係止部材における係止係合部に環状嵌合部の外側において当該環状嵌合部に形成されたスリットを部分的に塞ぐ位置をとらせるにあたっては、係止部材を、環状嵌合部の外周面部に係合させて、当該外周面部に沿って移動させるだけの、比較的大なる操作力が要されることのない、簡単な操作のみで足りる。   Under such circumstances, the locking member provided with the locking engagement portion is integrally formed of, for example, a bent plate material or a cut metal material, and is annularly fitted in the ground contact member. When the locking engagement portion of the locking member is engaged with the outer peripheral surface portion of the annular fitting portion, the periphery of the outer peripheral surface portion is assumed to be detachably engaged with the outer peripheral surface portion of the portion. The arrangement that is allowed to move around is relatively simple. Further, when the locking engagement portion of the locking member has a position where the slit formed in the annular fitting portion is partially closed outside the annular fitting portion, the locking member is connected to the annular fitting portion. It is only necessary to perform a simple operation that does not require a relatively large operating force, and is only required to be engaged with the outer peripheral surface portion and moved along the outer peripheral surface portion.

これよりして、本願発明に係る同軸コネクタ装置によれば、同軸ケーブルの中心導体が接続されるコンタクト部材と、同軸ケーブルの外側導体が接続されるグラウンドコンタクト部材と、コンタクト部材とグラウンドコンタクト部材とを相互絶縁状態をもって支持する絶縁ハウジング部材とを含んで構成されるコネクタ本体と、コネクタ本体とは別体に形成されてコネクタ本体のグラウンドコンタクト部材に装着される係止部材とを含んで成るもとで、回路基板に取り付けられた相手方コネクタ装置に機械的かつ電気的に連結されて用いられるにあたり、比較的簡単な構成をもって、比較的大なる操作力を要することなく、相手方コネクタ装置との機械的かつ電気的な連結をその不所望な解除を回避すべく確実に維持することができることになる。   Thus, according to the coaxial connector device according to the present invention, the contact member to which the central conductor of the coaxial cable is connected, the ground contact member to which the outer conductor of the coaxial cable is connected, the contact member and the ground contact member, A connector main body including an insulating housing member that supports each other in a mutually insulated state, and a locking member that is formed separately from the connector main body and is attached to the ground contact member of the connector main body.

本願発明を実施するための形態は、以下に述べられる本願発明についての実施例１及び実施例２をもって説明される。   The form for implementing this invention is demonstrated with Example 1 and Example 2 about this invention described below.

図１は、本願発明に係る同軸コネクタ装置の第１の例を成す同軸コネクタ装置１０を示す。図１に示される同軸コネクタ装置１０は、コネクタ本体１１とコネクタ本体１１とは別体に形成された係止部材１２とを備えて構成されている。   FIG. 1 shows a coaxial connector device 10 constituting a first example of a coaxial connector device according to the present invention. A coaxial connector device 10 shown in FIG. 1 includes a connector main body 11 and a locking member 12 formed separately from the connector main body 11.

コネクタ本体１１は、同軸ケーブルの一端部に装着されて用いられるものとされている。コネクタ本体１１が一端部に装着される同軸ケーブル１３は、後述される図４に示されるように、中心導体１４と、中心導体１４を密着包囲する内部絶縁体１５と、内部絶縁体１５を密着包囲する外側導体１６と、外側導体１６を密着包囲する表皮絶縁体１７とを有している。斯かる同軸ケーブル１３におけるコネクタ本体１１が装着される一端部は、表皮絶縁体１７が部分的に切除されて外側導体１６が露出するとともに、その外側導体１６及び内部絶縁体１５の夫々が部分的に切除されて中心導体１４が露出する状態におかれる。   The connector body 11 is used by being attached to one end of a coaxial cable. As shown in FIG. 4 to be described later, the coaxial cable 13 to which the connector body 11 is attached at one end is in close contact with the central conductor 14, the internal insulator 15 that tightly surrounds the central conductor 14, and the internal insulator 15. It has an outer conductor 16 that surrounds it and a skin insulator 17 that tightly surrounds the outer conductor 16. At one end of the coaxial cable 13 to which the connector main body 11 is attached, the skin insulator 17 is partially cut away to expose the outer conductor 16, and the outer conductor 16 and the inner insulator 15 are partially exposed. And the central conductor 14 is exposed.

斯かるもとで、コネクタ本体１１は、図２に示されるように、主要構成要素として、弾性導電性材料により形成されて、同軸ケーブル１３の中心導体１４との電気的接続がなされるものとされたコンタクト部材２０と、弾性導電性材料により形成されて、同軸ケーブル１３の外側導体１６との電気的接続がなされるものとされたグラウンドコンタクト部材２１と、合成樹脂材等の絶縁材料により形成されて、コンタクト部材２０とグラウンドコンタクト部材２１とを相互絶縁状態をもって支持する絶縁ハウジング部材２２とを備えている。   Under such circumstances, as shown in FIG. 2, the connector main body 11 is formed of an elastic conductive material as a main component and is electrically connected to the central conductor 14 of the coaxial cable 13. The contact member 20 is made of an elastic conductive material, and is made of an insulating material such as a synthetic resin material, and a ground contact member 21 that is electrically connected to the outer conductor 16 of the coaxial cable 13. In addition, an insulating housing member 22 that supports the contact member 20 and the ground contact member 21 in a mutually insulated state is provided.

絶縁ハウジング部材２２は、コンタクト部材２０を保持した基部２３を有している。そして、基部２３には、コンタクト部材２０に接続される同軸ケーブル１３の中心導体１４を支持する中心導体支持部２４が設けられており、また、基部２３の一端からは、折曲可能とされて、折り曲げられたときコンタクト部材２０に押圧当接する状態をとる折曲当接部２５が伸びている。   The insulating housing member 22 has a base 23 that holds the contact member 20. The base 23 is provided with a center conductor support 24 that supports the center conductor 14 of the coaxial cable 13 connected to the contact member 20, and can be bent from one end of the base 23. The bent contact portion 25 is in a state of being pressed against the contact member 20 when bent.

グラウンドコンタクト部材２１は、絶縁ハウジング部材２２の基部２３を包囲する環状嵌合部２６を有している。環状嵌合部２６は、その仮想中心軸が図２に示される仮想中心軸線Ｃｘをもってあらわされる筒状体を成していて、この仮想中心軸線Ｃｘに沿う方向にのびるスリット２７（後述される図６及び図１０等に現れている。）が形成されたものとされている。そして、スリット２７が形成された環状嵌合部２６は、それが具える弾性をもって、一時的にスリット２７を拡幅させて内径を増大させる外方への拡大変形及び斯かる拡大変形を生じた状態から元の状態に戻る縮小変形を生じ得るものとされている。また、環状嵌合部２６には、図１に示されるように、その内面部に形成されて内側に突出する突起部を成す係合部２８が設けられている。このような絶縁ハウジング部材２２の基部２３とそれを包囲するグラウンドコンタクト部材２１の環状嵌合部２６とは、コネクタ本体１１における嵌合連結部を構成しており、同軸ケーブル１３の一端部に装着されたコネクタ本体１１は、斯かる嵌合連結部をもって、相手方コネクタ装置に嵌合連結される。その際、環状嵌合部２６は、相手方コネクタ装置のグラウンドコンタクト部に嵌合接続される。   The ground contact member 21 has an annular fitting portion 26 that surrounds the base portion 23 of the insulating housing member 22. The annular fitting portion 26 forms a cylindrical body whose virtual center axis is represented by the virtual center axis Cx shown in FIG. 2, and a slit 27 (described later) extending in the direction along the virtual center axis Cx. 6 and FIG. 10 etc.) are formed.

そして、コネクタ本体１１におけるグラウンドコンタクト部材２１の環状嵌合部２６についての相手方コネクタ装置４０におけるグラウンドコンタクト部５０との嵌合接続状態が意図的に解除されるときには、環状嵌合部２６が相手方コネクタ装置４０におけるグラウンドコンタクト部５０との嵌合接続状態におかれ、係止部材１２が環状嵌合部２６における外周面部に係合せしめられて係止作用位置におかれたもとで、係止部材１２が、係止作用位置から非係止作用位置へと環状嵌合部２６に対して回動せしめられた後、環状嵌合部２６における外周面部から取り外される。そして、グラウンドコンタクト部材２１の環状嵌合部２６にそれを相手方コネクタ装置４０のグラウンドコンタクト部５０から離隔させるための適切な外力が作用せしめられ、それにより、環状嵌合部２６が、一時的に、それに形成されたスリット２７を拡幅させて内径を増大させる外方への拡大変形を生じ、その内面部に設けられた係合部２８を相手方コネクタ装置４０におけるグラウンドコンタクト部５０の外面部に設けられた被係合部５２から外れるものとして、相手方コネクタ装置４０におけるグラウンドコンタクト部５０との嵌合接続状態を解除する。   And when the fitting connection state with the ground contact part 50 in the other party connector apparatus 40 about the annular fitting part 26 of the ground contact member 21 in the connector main body 11 is intentionally cancelled | released, the annular fitting part 26 is the other party connector. The locking member 12 is placed in a fitting connection state with the ground contact portion 50 in the device 40 and the locking member 12 is engaged with the outer peripheral surface portion of the annular fitting portion 26 and placed in the locking action position. However, after being rotated with respect to the annular fitting portion 26 from the locking action position to the non-locking action position, it is removed from the outer peripheral surface portion of the annular fitting portion 26. Then, an appropriate external force is applied to the annular fitting portion 26 of the ground contact member 21 so as to separate it from the ground contact portion 50 of the counterpart connector device 40, whereby the annular fitting portion 26 is temporarily Then, the slit 27 formed therein is widened to cause outward expansion deformation to increase the inner diameter, and the engaging portion 28 provided on the inner surface portion is provided on the outer surface portion of the ground contact portion 50 in the mating connector device 40.

同軸コネクタ装置６０を構成するコネクタ本体６１の同軸ケーブル６３の一端部への装着は、前述の同軸コネクタ装置１０を構成するコネクタ本体１１の同軸ケーブル１３の一端部への装着と同様に行われるものとされる。   The connector main body 61 constituting the coaxial connector device 60 is attached to one end of the coaxial cable 63 in the same manner as the connector main body 11 constituting the coaxial connector device 10 is attached to one end of the coaxial cable 13. It is said.

図１９は、同軸ケーブル６３の一端部に装着されたコネクタ本体６１が、回路基板７１における部品等搭載面７２上に固定された相手方コネクタ装置７０に機械的かつ電気的に連結された状態を、コネクタ本体６１が備えるグラウンドコンタクト部材２１の環状嵌合部２６における外周面部に着脱可能に係合せしめられる係止部材６２と共に示す。図１９に示されるようなコネクタ本体６１が相手方コネクタ装置７０に機械的かつ電気的に連結された状態がとられる際には、コネクタ本体６１におけるグラウンドコンタクト部材２１の環状嵌合部２６が相手方コネクタ装置７０のグラウンドコンタクト部５０に嵌合接続され、それに伴って、グラウンドコンタクト部材２１の環状嵌合部２６における内面部に設けられた係合部２８が、グラウンドコンタクト部５０における外面部に設けられた被係合部５２に係合した状態におかれ、それにより、グラウンドコンタクト部材２１の環状嵌合部２６のグラウンドコンタクト部５０との嵌合接続状態が安定したものとされる。   FIG. 19 shows a state in which the connector main body 61 attached to one end of the coaxial cable 63 is mechanically and electrically connected to the mating connector device 70 fixed on the component mounting surface 72 of the circuit board 71. It is shown together with a locking member 62 that is detachably engaged with the outer peripheral surface portion of the annular fitting portion 26 of the ground contact member 21 provided in the connector main body 61. When the connector main body 61 as shown in FIG. 19 is mechanically and electrically connected to the counterpart connector device 70, the annular fitting portion 26 of the ground contact member 21 in the connector main body 61 is connected to the counterpart connector. The engagement portion 28 provided on the inner surface portion of the annular fitting portion 26 of the ground contact member 21 is provided on the outer surface portion of the ground contact portion 50. Thus, the engaged state of the annular contact portion 21 of the ground contact member 21 with the ground contact portion 50 is stabilized.

その後、上述のようにしてコネクタ本体６１におけるグラウンドコンタクト部材２１の環状嵌合部２６が相手方コネクタ装置７０のグラウンドコンタクト部５０に嵌合接続されたもとにおいて、図２０〜図２２に示されるように、係止部材６２が、コネクタ本体６１におけるグラウンドコンタクト部材２１の環状嵌合部２６における外周面部に着脱可能に係合せしめられる。斯かる際には、グラウンドコンタクト部材２１の環状嵌合部２６が、係止部材６２に設けられた係止係合部６４における相互対向する一対の係止端部６４ａの間が成す係合開口部を通過する状態がとられて、係止部材６２がグラウンドコンタクト部材２１の環状嵌合部２６に取り付けられるものとされ、係止部材６２に設けられた係止係合部６４が、グラウンドコンタクト部材２１の環状嵌合部２６における外周面部の周囲を廻る移動が可能とされて配されるとともに、係止部材６２に設けられた平板状部６５が、屈曲せしめられたグラウンドコンタクト部材２１のシェル部２９の外側において当該シェル部２９に近接もしくは当接するものとされる。このとき、係止部材６２は、非係止作用位置におかれたものとされている。   Thereafter, as described above, with the annular fitting portion 26 of the ground contact member 21 in the connector main body 61 being fitted and connected to the ground contact portion 50 of the mating connector device 70, as shown in FIGS. The locking member 62 is detachably engaged with the outer peripheral surface portion of the annular fitting portion 26 of the ground contact member 21 in the connector main body 61. In such a case, the annular fitting portion 26 of the ground contact member 21 has an engagement opening formed between a pair of locking end portions 64 a opposed to each other in the locking engagement portion 64 provided in the locking member 62. The locking member 62 is attached to the annular fitting portion 26 of the ground contact member 21, and the locking engagement portion 64 provided on the locking member 62 is connected to the ground contact. The annular contact portion 26 of the member 21 is arranged so as to be movable around the outer peripheral surface portion, and the flat plate portion 65 provided on the locking member 62 is bent in the shell of the ground contact member 21. It is assumed that the shell portion 29 approaches or comes into contact with the outside of the portion 29. At this time, the locking member 62 is placed in the non-locking action position.

続いて、非係止作用位置におかれた係止部材６２が、例えば、平板状部６５に設けられた溝部６８に所定の冶具が係合して回動することにより、係止係合部６４にグラウンドコンタクト部材２１の環状嵌合部２６における外周面部の周囲を廻る移動をさせつつ、グラウンドコンタクト部材２１の環状嵌合部２６に対して回動せしめられ、その結果、図２１及び図２２に示されるような、係止作用位置におかれたものとされる。このようにして、係止部材６２が係止作用位置におかれたもとにあっては、係止部材６２に設けられた係止係合部６４が、グラウンドコンタクト部材２１の環状嵌合部２６に形成されたスリットを部分的に塞ぐ位置をもって、環状嵌合部２６をその外側から係止して、環状嵌合部２６についてのスリットを拡幅させる外方への拡大変形を規制する。   Subsequently, the locking member 62 placed in the non-locking position is rotated by engaging a predetermined jig with a groove 68 provided in the flat plate portion 65, for example. 64 is rotated with respect to the annular fitting portion 26 of the ground contact member 21 while moving around the outer peripheral surface portion of the annular fitting portion 26 of the ground contact member 21, and as a result, FIGS. 21 and 22. As shown in FIG. Thus, when the locking member 62 is in the locking position, the locking engagement portion 64 provided on the locking member 62 is connected to the annular fitting portion 26 of the ground contact member 21. At a position where the formed slit is partially blocked, the annular fitting portion 26 is locked from the outside, and the outward expansion deformation that widens the slit of the annular fitting portion 26 is restricted.

係止部材６２がグラウンドコンタクト部材２１の環状嵌合部２６に対して回動せしめられ、それに伴って係止部材６２に設けられた係止係合部６４がグラウンドコンタクト部材２１の環状嵌合部２６における外周面部の周囲を廻る移動を行うときには、係止部材６２における連結部６６に設けられたストッパー部６７が、グラウンドコンタクト部材２１の一部である、例えば、特に図２２に示されるように、グラウンドコンタクト部材２１におけるシェル部２９に設けられた第１の折曲係合部３１に当接し、それによって係止係合部６４の過剰な移動を阻止する状態をとる。   The locking member 62 is rotated with respect to the annular fitting portion 26 of the ground contact member 21, and accordingly, the locking engagement portion 64 provided on the locking member 62 is connected to the annular fitting portion of the ground contact member 21. When the movement around the outer peripheral surface portion in 26 is performed, the stopper portion 67 provided in the connecting portion 66 in the locking member 62 is a part of the ground contact member 21, for example, as shown in FIG. Then, the ground contact member 21 is brought into contact with the first bent engagement portion 31 provided in the shell portion 29, thereby preventing excessive movement of the locking engagement portion 64.

このようにして、同軸ケーブル６３の一端部に装着されたコネクタ本体６１におけるグラウンドコンタクト部材２１の環状嵌合部２６が、相手方コネクタ装置７０のグラウンドコンタクト部５０に嵌合接続されるとともに、係止部材６２が、コネクタ本体６１におけるグラウンドコンタクト部材２１の環状嵌合部２６における外周面部に係合せしめられて係止作用位置におかれたもとにあっては、前述の同軸コネクタ装置１０の場合と同様にして、コネクタ本体６１における絶縁ハウジング部材により支持されて、その中心導体接続部に同軸ケーブル６３の中心導体が接続されたコンタクト部材における、絶縁ハウジング部材内を相互対向して伸びる一対の弾性舌片部の夫々が、相手方コネクタ装置７０のシグナルコンタクト部における円柱状部を成す接触接続部に接触接続されたものとされる。それにより、同軸ケーブル６３の中心導体が、コネクタ本体６１におけるコンタクト部材及び相手方コネクタ装置７０のシグナルコンタクト部を通じて、回路基板７１の部品等搭載面７２に設けられたシグナル端子に連結され、また、同軸ケーブル６３の外側導体が、コネクタ本体６１におけるグラウンドコンタクト部材２１及び相手方コネクタ装置７０のグラウンドコンタクト部５０を通じて、回路基板７１に設けられた接地端子に連結された状態が得られる。   In this manner, the annular fitting portion 26 of the ground contact member 21 in the connector main body 61 attached to one end portion of the coaxial cable 63 is fitted and connected to the ground contact portion 50 of the mating connector device 70 and is locked. When the member 62 is engaged with the outer peripheral surface portion of the annular fitting portion 26 of the ground contact member 21 in the connector main body 61 and placed in the locking action position, the same as in the case of the coaxial connector device 10 described above. Thus, a pair of elastic tongues extending in opposite directions in the insulating housing member in the contact member supported by the insulating housing member in the connector body 61 and having the central conductor connecting portion connected to the central conductor of the coaxial cable 63. Each of the portions is a cylinder in the signal contact portion of the mating connector device 70 Parts are those contacts connected to the contacting portion forming the. As a result, the central conductor of the coaxial cable 63 is connected to the signal terminal provided on the mounting surface 72 such as the component of the circuit board 71 through the contact member in the connector main body 61 and the signal contact portion of the counterpart connector device 70, A state in which the outer conductor of the cable 63 is connected to the ground terminal provided on the circuit board 71 through the ground contact member 21 in the connector main body 61 and the ground contact portion 50 of the counterpart connector device 70 is obtained.

そして、このとき、同軸コネクタ装置１０の場合と同様の態様をもって、コネクタ本体６１におけるグラウンドコンタクト部材２１の環状嵌合部２６についての相手方コネクタ装置７０におけるグラウンドコンタクト部５０との嵌合接続状態が安定に維持され、それにより、同軸コネクタ装置６０の相手方コネクタ装置７０との機械的かつ電気的な連結が、その不所望な解除が回避されて、確実に維持されることになる。   At this time, in the same manner as in the case of the coaxial connector device 10, the fitting connection state with the ground contact portion 50 in the mating connector device 70 with respect to the annular fitting portion 26 of the ground contact member 21 in the connector main body 61 is stable. Thus, the mechanical and electrical connection of the coaxial connector device 60 with the mating connector device 70 is reliably maintained while avoiding its undesirable release.

上述のような本願発明に係る同軸コネクタ装置の第２の例を成す同軸コネクタ装置６０によれば、回路基板７１に装着された相手方コネクタ装置７０に機械的かつ電気的に連結されるにあたり、コネクタ本体６１におけるグラウンドコンタクト部材２１の環状嵌合部２６が相手方コネクタ装置７０のグラウンドコンタクト部５０に嵌合接続されて、係止部材６２が環状嵌合部２６における外周面部に着脱可能に係合せしめられて係止作用位置におかれるものとされることにより、相手方コネクタ装置７０におけるグラウンドコンタクト部５０に嵌合接続された環状嵌合部２６に、相手方コネクタ装置７０におけるグラウンドコンタクト部５０との嵌合接続状態を解除させてグラウンドコンタクト部５０から離隔させようとする不所望な外力が作用しても、係止作用位置をとるものとされた係止部材６２における係止係合部６４が、環状嵌合部２６をそれに形成されたスリットを部分的に塞ぐ位置をもって外側から係止して、環状嵌合部２６のスリットを拡幅させる外方への拡大変形を規制して、環状嵌合部２６に相手方コネクタ装置７０におけるグラウンドコンタクト部５０との嵌合接続状態を維持させることができ、その結果、同軸コネクタ装置６０の相手方コネクタ装置７０との機械的かつ電気的な連結が、その不所望な解除が回避されて、確実に維持されることになる。   According to the coaxial connector device 60 constituting the second example of the coaxial connector device according to the present invention as described above, the connector is mechanically and electrically connected to the mating connector device 70 mounted on the circuit board 71. The annular fitting portion 26 of the ground contact member 21 in the main body 61 is fitted and connected to the ground contact portion 50 of the mating connector device 70, and the locking member 62 is detachably engaged with the outer peripheral surface portion of the annular fitting portion 26. The engagement with the ground contact portion 50 in the mating connector device 70 is fitted into the annular fitting portion 26 that is mated and connected to the ground contact portion 50 in the mating connector device 70. An undesired external force that releases the joint connection state and separates it from the ground contact portion 50 Even if it uses, the latching engagement part 64 in the latching member 62 which took the latching action position latches the annular fitting part 26 from the outside with the position which partially closes the slit formed in it. Then, the outward expansion deformation that widens the slit of the annular fitting portion 26 is restricted, and the annular fitting portion 26 is maintained in the fitting connection state with the ground contact portion 50 in the mating connector device 70. As a result, the mechanical and electrical connection of the coaxial connector device 60 with the mating connector device 70 can be reliably maintained while avoiding the undesirable release.

それに加えて、係止部材６２における連結部６６に、各々が連結部６６からその外方に突出する一対のストッパー部６７が設けられていることにより、コネクタ本体６１のグラウンドコンタクト部材２１の環状嵌合部２６における外周面部に係合せしめられた係止部材６２が係止作用位置をとるべく回動せしめられ、それに伴って係止部材６２に設けられた係止係合部６４がグラウンドコンタクト部材２１の環状嵌合部２６における外周面部の周囲を廻る移動を行うとき、ストッパー部６７がグラウンドコンタクト部材２１の一部に当接し、それによって係止係合部６４の過剰な移動が阻止される。   In addition, the coupling portion 66 of the locking member 62 is provided with a pair of stopper portions 67 each projecting outward from the coupling portion 66, so that the ground contact member 21 of the connector main body 61 is annularly fitted. The locking member 62 engaged with the outer peripheral surface portion of the joint portion 26 is rotated to take the locking action position, and accordingly, the locking engagement portion 64 provided on the locking member 62 is a ground contact member. When the movement around the outer peripheral surface portion of the annular fitting portion 26 of 21 is performed, the stopper portion 67 abuts a part of the ground contact member 21, thereby preventing excessive movement of the locking engagement portion 64. .

斯かるもとで、係止部材６２が、例えば、金属材料に切削加工が施されて一体に形成され、コネクタ本体６１におけるグラウンドコンタクト部材２１の環状嵌合部２６における外周面部に着脱可能に係合せしめられて、係止作用位置と非係止作用位置とを選択的にとるものとされる構成は、比較的簡単な構成とされる。また、係止部材６２をコネクタ本体６１におけるグラウンドコンタクト部材２１の環状嵌合部２６における外周面部に着脱可能に係合させて係止作用位置におくにあたっては、係止部材６２を、それに設けられた係止係合部６４が形成する係合開口部を利用してグラウンドコンタクト部材２１の環状嵌合部２６に取り付け、環状嵌合部２６に対して回動させるだけの、比較的大なる操作力が要されることのない、簡単な操作のみで足りる。   Under such circumstances, the locking member 62 is integrally formed, for example, by cutting a metal material, and is detachably engaged with the outer peripheral surface portion of the annular fitting portion 26 of the ground contact member 21 in the connector main body 61. A configuration in which the locking action position and the non-locking action position are selectively taken together is a relatively simple structure. Further, when the locking member 62 is detachably engaged with the outer peripheral surface portion of the annular fitting portion 26 of the ground contact member 21 in the connector main body 61 and placed in the locking action position, the locking member 62 is provided on the locking member 62. A relatively large operation that is simply attached to the annular fitting portion 26 of the ground contact member 21 using the engagement opening formed by the locking engagement portion 64 and rotated relative to the annular fitting portion 26. A simple operation that does not require force is sufficient.

以上のような本願発明に係る同軸コネクタ装置は、同軸ケーブルの中心導体が接続されるコンタクト部材と、同軸ケーブルの外側導体が接続されるグラウンドコンタクト部材と、コンタクト部材とグラウンドコンタクト部材とを相互絶縁状態をもって支持する絶縁ハウジング部材とを含んで構成され、回路基板に取り付けられた相手方コネクタ装置に機械的かつ電気的に連結されて用いられるにあたり、比較的簡単な構成をもって、比較的大なる操作力を要することなく、相手方コネクタ装置との機械的かつ電気的な連結をその不所望な解除を回避すべく確実に維持することができるものとして、各種の電子機器等に広く適用され得るものである。   The coaxial connector device according to the present invention as described above includes a contact member to which a central conductor of a coaxial cable is connected, a ground contact member to which an outer conductor of the coaxial cable is connected, and a contact member and a ground contact member that are mutually insulated. And a relatively large operating force with a relatively simple configuration when used mechanically and electrically connected to a mating connector device attached to a circuit board. And can be widely applied to various electronic devices and the like as being able to reliably maintain the mechanical and electrical connection with the counterpart connector device so as to avoid undesired release thereof. .
