Description

コネクタ装置connector device
　本開示は、コネクタ装置に関するものである。 The present disclosure relates to a connector device.
　特許文献１には、一対の回路基板に個別に実装される一対のコネクタと、一対のコネクタの間に設けた複数のアダプターとを備えたコネクタ装置が開示されている。コネクタには、内導体と誘電体と外導体とからなる複数の端子部が取り付けられている。アダプターは、内導体と誘電体と外導体とを有する棒状の部材である。複数のアダプターの両端部は、複数の端子部に対して個別に接続されている。内導体から発するノイズの漏れは、外導体によって抑制されている。 Patent Document 1 discloses a connector device including a pair of connectors individually mounted on a pair of circuit boards and a plurality of adapters provided between the pair of connectors. A plurality of terminal portions each including an inner conductor, a dielectric and an outer conductor are attached to the connector.

　上記のコネクタ装置では、回路基板間の距離と、内導体を流れる伝送信号の周波数によっては、内導体から発するノイズによって共振が発生し得る。共振防止の対策としては、回路基板に形成されている伝送路を細くしたり、伝送路を回路基板の裏面側に配置する等の対策が考えられる。しかし、回路基板において共振対策を行おうとすると、回路基板における伝送路の設計の自由度が低下する。 In the above connector device, depending on the distance between the circuit boards and the frequency of the transmission signal flowing through the inner conductor, resonance may occur due to noise emitted from the inner conductor. As countermeasures for preventing resonance, it is conceivable to reduce the thickness of the transmission line formed on the circuit board, arrange the transmission line on the back side of the circuit board, or the like. However, when trying to take measures against resonance on the circuit board, the degree of freedom in designing the transmission line on the circuit board is reduced.
　本開示のコネクタ装置は、上記のような事情に基づいて完成されたものであって、回路基板における設計自由度を低下させることなく、共振を防止することを目的とする。 The connector device of the present disclosure has been completed based on the circumstances as described above, and aims to prevent resonance without lowering the degree of freedom in designing the circuit board.

　アライメント部材６０は、６つのアダプター５１に対し、上方から各貫通孔６４を個別に嵌合させることによって組み付けられている。アライメント部材６０は、段差部５５に対して貫通孔６４の孔縁部を係止させることによって、アダプター５１に対する下方への変位を規制され、所定高さに保持されている。アライメント部材６０は、係止突起５６に貫通孔６４の孔縁部を係止させることによって、アダプター５１から上方へ離脱することを規制されている。６つのアダプター５１は、アライメント部材６０に取り付けられることによって、前後方向及び左右方向へ一体的に揺動し得るように連結されている。 The alignment member 60 is assembled to the six adapters 51 by individually fitting the through holes 64 from above.

Since the conducting contact surface 26 is a two-dimensional plane that extends in the vertical direction and the horizontal direction, even if the alignment member 60 has variations in height, even if the alignment member 60 is displaced in the horizontal direction due to the swinging of the adapter 51, However, the contact state between the contact portion 66 and the conducting contact surface 26 is maintained. In addition, since the elastic arm portion 63 can be elastically deformed in the front-rear direction, even if the alignment member 60 is displaced in the front-rear direction as the adapter 51 swings, the contact state between the contact portion 66 and the conducting contact surface 26 remains unchanged. retained.

　金属部材であるアライメント部材６０を、導電路２８によって第１グランド回路１３に接続すると、アライメント部材６０の基板部６１と庇部６２が、第１グランド回路１３と同電位に保持される。金属材料からなる基板部６１と庇部６２は、６つの中継外導体５４よりも体積が大きいので、第１グランド回路１３及び第２グランド回路３３と同電位の中継グランド回路６７を構成する。中継グランド回路６７は、中継内導体５２からなる伝送路の長さ方向において、第１グランド回路１３と第２グラント回路３３との間に配置される。 When the alignment member 60 , which is a metal member, is connected to the first ground circuit 13 by the conductive path 28 , the substrate portion 61 and the eaves portion 62 of the alignment member 60 are held at the same potential as the first ground circuit 13 . Since the substrate portion 61 and the eaves portion 62 made of a metal material are larger in volume than the six relay outer conductors 54 , they form a relay ground circuit 67 having the same potential as the first ground circuit 13 and the second ground circuit 33 . The relay ground circuit 67 is arranged between the first ground circuit 13 and the second ground circuit 33 in the length direction of the transmission path made up of the relay inner conductor 52 .
　第１グランド回路１３と第２グランド回路３３との間に中継グランド回路６７を介在させると、図３に示すように、第１グランド回路１３と中継グランド回路６７との間の距離Ｌ１、及び第２グランド回路３３と中継グランド回路６７との間の距離Ｌ２が、第１グランド回路１３と第２グランド回路３３との間の距離Ｌ３よりも短くなる。中継内導体５２から発するノイズによって共振が生じるときの伝送信号の周波数である共振周波数は、隣り合うグランド回路１３，３３，６７間の距離Ｌ１，Ｌ２，Ｌ３によって決まる。中継グランド回路６７を介在させて隣り合うグランド回路１３，６７間の距離Ｌ１、及び隣り合うグランド回路３３，６７間の距離Ｌ２を短くすると、共振周波数が中継グランド回路６７を介在させない場合よりも高周波帯域へ遷移する。 If the relay ground circuit 67 is interposed between the first ground circuit 13 and the second ground circuit 33, as shown in FIG. A distance L2 between the second ground circuit 33 and the relay ground circuit 67 is shorter than a distance L3 between the first ground circuit 13 and the second ground circuit 33 . The resonance frequency, which is the frequency of the transmission signal when resonance occurs due to noise emitted from the relay inner conductor 52, is determined by the distances L1, L2, and L3 between the adjacent ground circuits 13, 33, and 67. FIG. If the distance L1 between the adjacent ground circuits 13 and 67 and the distance L2 between the adjacent ground circuits 33 and 67 are shortened by interposing the relay ground circuit 67, the resonance frequency becomes higher than when the relay ground circuit 67 is not interposed. Transition to band.
　第１グランド回路１３と第２グランド回路３３との間に中継グランド回路６７が介在しない場合の共振周波数を、中継内導体５２における信号伝送用の周波数として使用する場合に、中継グランド回路６７を介在させることによって共振の発生を防止することができる。したがって、第１回路基板１１と第２回路基板３１のいずれにおいても共振対策を行う必要がなく、共振対策のために両回路基板１１，３１における回路設計等の自由度が低下することはない。本実施例１によれば、第１回路基板１１及び第２回路基板３１における設計の自由度を低下させることなく、共振の発生を防止することができる。 When using the resonance frequency when the relay ground circuit 67 is not interposed between the first ground circuit 13 and the second ground circuit 33 as the frequency for signal transmission in the relay inner conductor 52, the relay ground circuit 67 is interposed. It is possible to prevent the occurrence of resonance by Therefore, there is no need to take countermeasures against resonance in either the first circuit board 11 or the second circuit board 31, and the degree of freedom in circuit design, etc., for both circuit boards 11 and 31 is not reduced due to the countermeasures against resonance. According to the first embodiment, it is possible to prevent resonance from occurring without lowering the degree of freedom in designing the first circuit board 11 and the second circuit board 31 .
　コネクタ装置は、第１回路基板１１に取り付けられた複数の第１シールド端子１６と、第２回路基板３１に取り付けられた複数の第２シールド端子３６と、複数のアダプター５１とを備えている。複数のアダプター５１は、中継内導体５２と中継外導体５４とを有し、複数の第１シールド端子１６と複数の第２シールド端子３６を個別に接続する。複数のアダプター５１は、アライメント部材６０によって一体的に揺動し得る状態に保持されている。この構成によれば、中継グランド回路６７を構成する共振防止用の金属部材（アライメント部材６０）が、複数のアダプター５１を一体的に揺動し得る状態に保持するアライメント機能を兼ね備えているので、中継グランド回路６７を構成する共振防止用の金属部材と、複数のアダプター５１を一体的に揺動する専用のアライメント用の部材とを、別部材として設ける場合に比べると、部品点数を削減できる。 The connector device includes a plurality of first shield terminals 16 attached to the first circuit board 11, a plurality of second shield terminals 36 attached to the second circuit board 31, and a plurality of adapters 51.

According to this configuration, the resonance-preventing metal member (alignment member 60) constituting the relay ground circuit 67 also has an alignment function of holding the plurality of adapters 51 in a state in which they can be swung integrally. The number of parts can be reduced compared to the case where the metal member for preventing resonance that constitutes the relay ground circuit 67 and the dedicated alignment member for integrally swinging the plurality of adapters 51 are provided as separate members.
　複数のアダプター５１を構成する複数の中継外導体５４同士が、金属部材であるアライメント部材６０によって導通可能に接続されている。複数の中継外導体５４がアライメント部材６０を介して同電位に保持されているので、中継外導体５４によるシールド性能を高めることができる。 A plurality of relay outer conductors 54 constituting a plurality of adapters 51 are electrically connected to each other by an alignment member 60 that is a metal member. Since the plurality of relaying outer conductors 54 are held at the same potential via the alignment member 60, the shielding performance of the relaying outer conductors 54 can be enhanced.

Conductive path 28 includes first fixing member 23 . Since the first fixing member 23 also functions as the conductive path 28 , the first connector 14 does not need to be provided with a component that constitutes the conductive path 28 in addition to the first fixing member 23 .
　アライメント部材６０を第１グランド回路１３に接続することによって中継グランド回路６７を構成した。第１グランド回路１３は、中継外導体５４が接続される回路である。第１グランド回路１３とは別に、アライメント部材６０を接続するためのグランドを第１回路基板１１に設ける場合に比べると、本実施例１のコネクタ装置は、第１回路基板１１における回路構成が複雑になることを回避できる。 A relay ground circuit 67 is configured by connecting the alignment member 60 to the first ground circuit 13 . The first ground circuit 13 is a circuit to which the relay outer conductor 54 is connected. Compared to the case where a ground for connecting the alignment member 60 is provided on the first circuit board 11 separately from the first ground circuit 13, the connector device of the first embodiment has a complicated circuit configuration on the first circuit board 11. can be avoided.
