Description

本発明は複数の端子を有するコネクタに関する。 The present invention relates to connectors having multiple terminals.

近時、例えば、映像および音声の再生並びに通信等の機能を有する複合装置に対し、複数の信号の高速伝送を一括して行う技術が求められている。このような技術の分野において、複数対の差動信号の並列伝送を行うことができるコネクタが知られている。差動信号を伝送するためには、互いに隣接する一対の信号端子と、当該一対の信号端子の両側に配置された一対のグランド端子とからなる端子群をコネクタに設けることが望ましい。複数対の差動信号の並列伝送を行うことができるコネクタには、このような端子群が複数設けられている。例えば、下記の特許文献１には、このような構成を有するコネクタが記載されている。 2. Description of the Related Art In recent years, there has been a demand for a technique for collectively performing high-speed transmission of a plurality of signals for a multifunction device having functions such as video and audio reproduction and communication. Connectors capable of parallel transmission of a plurality of pairs of differential signals are known in such a technical field. In order to transmit differential signals, it is desirable to provide a connector with a terminal group consisting of a pair of signal terminals adjacent to each other and a pair of ground terminals arranged on both sides of the pair of signal terminals. A connector capable of parallel transmission of a plurality of pairs of differential signals is provided with a plurality of such terminal groups. For example, Patent Document 1 below describes a connector having such a configuration.

特開２０１５－１５８９９２号公報JP 2015-158992 A

上記特許文献１に記載のコネクタには、同文献の図５に示されているように、互いに隣接する一対の信号コンタクトと、当該一対の信号コンタクトの両側に配置された一対のグランドコンタクトからなるコンタクト群が複数設けられており、当該コネクタにより複数対の差動信号を伝送することができる。 As shown in FIG. 5 of the document, the connector described in Patent Document 1 includes a pair of signal contacts adjacent to each other and a pair of ground contacts arranged on both sides of the pair of signal contacts. A plurality of contact groups are provided, and the connector can transmit a plurality of pairs of differential signals.

しかしながら、このコネクタにおいては、同文献の図２および図４に示されているように、コネクタの後部において、それぞれのコンタクト群を構成する複数本のコンタクトの後端側が狭い間隔をもって配置されている。この結果、一対の差動信号を伝送する信号コンタクトの対と、他の一対の差動信号を伝送する信号コンタクトの対とが互いに接近している。このため、コネクタの後部において、複数対の差動信号間のクロストークが発生し易いという問題がある。 However, in this connector, as shown in FIGS. 2 and 4 of the same document, the rear ends of the multiple contacts forming each contact group are arranged at narrow intervals at the rear of the connector. . As a result, a pair of signal contacts transmitting a pair of differential signals and a pair of signal contacts transmitting another pair of differential signals are close to each other. Therefore, there is a problem that crosstalk between a plurality of pairs of differential signals is likely to occur at the rear of the connector.

また、特許文献１に記載のコネクタにおいては、複数本のコンタクトの後端に設けられた端子部（コンタクトを基板の回路に接続する部分）が狭い間隔をもって配置されている。この結果、一対の差動信号を伝送する端子部の対と、他の一対の差動信号を伝送する端子部の対とが互いに接近している。それゆえ、このコネクタが実装される基板においては、コネクタのそれぞれの端子部に接続される複数の回路パターンが狭い間隔をもって配置されることとなり、一対の差動信号を伝送する回路パターンの対と、他の一対の差動信号を伝送する回路パターンの対とが互いに接近することとなる。このため、基板の回路において、複数対の差動信号間のクロストークが発生し易くなるという問題がある。 Further, in the connector described in Patent Document 1, terminal portions (portions for connecting the contacts to the circuit on the substrate) provided at the rear ends of the plurality of contacts are arranged at narrow intervals. As a result, a pair of terminal portions for transmitting a pair of differential signals and a pair of terminal portions for transmitting another pair of differential signals are close to each other. Therefore, on the board on which this connector is mounted, a plurality of circuit patterns connected to the respective terminal portions of the connector are arranged with narrow intervals, and a pair of circuit patterns for transmitting a pair of differential signals is arranged. , and another pair of circuit patterns for transmitting differential signals are brought closer to each other. Therefore, there is a problem that crosstalk between a plurality of pairs of differential signals is likely to occur in the circuit on the board.

本発明は例えば上述したような問題に鑑みなされたものであり、本発明の課題は、複数対の差動信号のクロストークを抑制することができるコネクタを提供することにある。 SUMMARY OF THE INVENTION An object of the present invention is to provide a connector capable of suppressing crosstalk between a plurality of pairs of differential signals.

As a result, the first terminal group G1 and the second terminal group G2 are largely separated from each other at the rear portion of the connector 1 or the rear end side of the terminals 11-18. Therefore, at the rear portion of the connector 1 or on the rear end side of the terminals 11 to 18, the first high-speed differential signal transmitted by the first terminal group G1 and the second high-speed differential signal transmitted by the second terminal group G2 It is possible to suppress the occurrence of crosstalk with the differential signal. In addition, crosstalk is likely to occur at portions where the terminals 11 to 18 are bent and the extension direction changes from the front-rear direction to the vertical direction. Therefore, by separating the first terminal group G1 and the second terminal group G2 at the portions where the terminals 11 to 18 are bent, the effect of suppressing crosstalk can be enhanced.

また、第１の端子群Ｇ１の各端子１１～１４の接続部３２の群と、第２の端子群Ｇ２の各端子１５～１８の接続部３２の群とが互いの大きく離れているので、基板９１の回路において、第１の高速差動信号を伝送する回路パターンと、第２の高速差動信号を伝送する回路パターンとを互いに離すことができる。これにより、基板９１の回路において、第１の高速差動信号と第２の高速差動信号との間のクロストークを抑制することができる。 In addition, since the group of connection portions 32 of the terminals 11 to 14 of the first terminal group G1 and the group of connection portions 32 of the terminals 15 to 18 of the second terminal group G2 are far apart from each other, In the circuit of the substrate 91, the circuit pattern for transmitting the first high-speed differential signal and the circuit pattern for transmitting the second high-speed differential signal can be separated from each other. Thereby, crosstalk between the first high-speed differential signal and the second high-speed differential signal can be suppressed in the circuit of the substrate 91 .

また、コネクタ１において、第１の端子群Ｇ１の後端側と第２の端子群Ｇ２の後端側との間には、他の端子と比較して左右方向の寸法が大きく、電源端子または電源用のグランド端子として好適に用いることができる端子１９、２２が配置されている。第１の端子群Ｇ１と第２の端子群Ｇ２との間に、左右方向の寸法が大きい電源供給用の端子を配置することで、第１の端子群Ｇ１により伝送される第１の高速差動信号と、第２の端子群Ｇ２により伝送される第２の高速差動信号との間のクロストークを抑制することができる。すなわち、上記特許文献１に記載のコネクタにおいては、コネクタの後部（各端子の後端側）において高速差動信号を伝送する信号コンタクトの対同士が細い１本または２本のグランドコンタクトのみを挟んで配置されている。これに対し、本発明の実施形態のコネクタ１では、コネクタ１の後部（各端子１１～２２の後端側）において、第１の高速差動信号を伝送する一対の端子１２、１３と、第２の高速差動信号を伝送する一対の端子１６、１７とが、左右方向に寸法の大きい電源供給用の端子１９、２２を含む端子群等を挟んで配置されている。これにより、本発明の実施形態のコネクタ１によれば、上記特許文献１に記載のコネクタおよびそれと同様の端子配置構造を有するコネクタと比較して、高速差動信号間のクロストークの抑制効果を高めることができる。 Further, in the connector 1, the distance between the rear end side of the first terminal group G1 and the rear end side of the second terminal group G2 is larger than the other terminals in the horizontal direction. Terminals 19 and 22 that can be suitably used as ground terminals for power supply are arranged. By arranging a power supply terminal having a large lateral dimension between the first terminal group G1 and the second terminal group G2, the first high-speed difference transmitted by the first terminal group G1 can be obtained. Crosstalk between the dynamic signal and the second high-speed differential signal transmitted through the second terminal group G2 can be suppressed. That is, in the connector described in Patent Document 1, a pair of signal contacts for transmitting high-speed differential signals sandwich only one or two thin ground contacts at the rear portion of the connector (on the rear end side of each terminal). are placed in On the other hand, in the connector 1 according to the embodiment of the present invention, a pair of terminals 12 and 13 for transmitting a first high-speed differential signal and a second A pair of terminals 16 and 17 for transmitting two high-speed differential signals are arranged across a terminal group including terminals 19 and 22 for power supply, which are large in size, in the left-right direction. As a result, according to the connector 1 of the embodiment of the present invention, the effect of suppressing crosstalk between high-speed differential signals is greater than that of the connector described in Patent Document 1 and a connector having a similar terminal arrangement structure. can be enhanced.

また、コネクタ１において、第１の端子群Ｇ１の各端子１１～１４の上下伸長部３３には左傾斜部３６が形成され、第２の端子群Ｇ２の各端子１５～１８の上下伸長部３３には右傾斜部３７が形成され、各端子１１～１４の左傾斜部３６と各端子１５～１８の右傾斜部３７とは互いに平行ではない。これにより、コネクタ１内において、第１の高速差動信号の伝送経路と第２の高速差動信号の伝送経路とを部分的にでも非平行とすることができ、第１の高速差動信号と第２の高速差動信号との間のクロストークを抑制することができる。 In the connector 1, the vertically extending portions 33 of the terminals 11 to 14 of the first terminal group G1 are formed with left inclined portions 36, and the vertically extending portions 33 of the terminals 15 to 18 of the second terminal group G2 are formed. A right slanted portion 37 is formed in the terminal 11-14, and the left slanted portion 36 of each of the terminals 11-14 and the right slanted portion 37 of each of the terminals 15-18 are not parallel to each other. As a result, the transmission path of the first high-speed differential signal and the transmission path of the second high-speed differential signal can be partially made non-parallel in the connector 1, and the first high-speed differential signal and the second high-speed differential signal can be suppressed.

また、コネクタ１においては、コネクタ１が有する１２本のすべての端子１１～２２の接続部３２が左右方向に一列に配置されている。これにより、各接続部３２の基板９１の回路へのはんだ付けを容易かつ確実に行うことができる。また、はんだ付け作業後に行う、はんだ付けの良否の検査を容易化することができる。 Further, in the connector 1, the connecting portions 32 of all the twelve terminals 11 to 22 of the connector 1 are arranged in a row in the horizontal direction. This makes it possible to easily and reliably solder each connecting portion 32 to the circuit of the substrate 91 . In addition, it is possible to facilitate inspection of the quality of soldering performed after the soldering work.

また、コネクタ１によれば、第１、第２および第３の端子群Ｇ１～Ｇ３の各端子１１～２２において、接続部３２の左右方向の寸法を接触部３１の左右方向の寸法よりも小さくしたことにより、隣接する接続部３２間の間隔を十分に確保することができる。これにより、はんだフィレットを考慮したインピーダンス設定を行うことができる。 Further, according to the connector 1, in each of the terminals 11 to 22 of the first, second and third terminal groups G1 to G3, the lateral dimension of the connection portion 32 is smaller than the lateral dimension of the contact portion 31. By doing so, it is possible to sufficiently secure the interval between the adjacent connecting portions 32 . Thereby, the impedance can be set in consideration of the solder fillet.

また、コネクタ１においては、第３の端子群Ｇ３の各端子１９～２２の接触部３１が第１および第２の端子群Ｇ１、Ｇ２の各端子１１～１８の接触部３１よりも上方に位置し、第３の端子群Ｇ３の各端子１９～２２の上下伸長部３３が第１および第２の端子群Ｇ１、Ｇ２の各端子１１～１８の上下伸長部３３よりも後方に位置し、第１の端子群Ｇ１の各端子１１～１４の左傾斜部３６が各端子１１～１４の上下伸長部３３に形成され、第２の端子群Ｇ２の各端子１５～１８の右傾斜部３７が各端子１５～１８の上下伸長部３３に形成されている。これにより、例えば上記特許文献１に記載のコネクタと比較して、コネクタ１の前後方向の寸法を小さくすることができる。すなわち、上記特許文献１に記載のコネクタでは、同文献の図５に示すように、各コンタクトの交差部（傾斜部）が、コンタクトにおいてＸ方向（前後方向）に伸長している部分に形成されている。コンタクトにおける端子部を接触部よりもＹ方向（左右方向）のいずれか一方にずらすためには、交差部の長さをある程度長くしなければならない。交差部の長さが長くなると、コネクタがＸ方向に大きくなる。このため、特許文献１に記載のコネクタはコネクタの前後方向の寸法を小さくすることが難しい。これに対し、本発明の実施形態のコネクタ１によれば、左傾斜部３６および右傾斜部３７が形成されている箇所が各端子１１～１８の上下伸長部３３であるので、左傾斜部３６および右傾斜部３７が長くなったとしても、それによりコネクタ１の前後方向の寸法は大きくならない。 In the connector 1, the contact portions 31 of the terminals 19 to 22 of the third terminal group G3 are positioned above the contact portions 31 of the terminals 11 to 18 of the first and second terminal groups G1 and G2. The vertically extending portions 33 of the terminals 19 to 22 of the third terminal group G3 are located behind the vertically extending portions 33 of the terminals 11 to 18 of the first and second terminal groups G1 and G2. The left inclined portions 36 of the terminals 11 to 14 of the first terminal group G1 are formed on the vertically extending portions 33 of the terminals 11 to 14, and the right inclined portions 37 of the terminals 15 to 18 of the second terminal group G2 are formed on the respective terminals. It is formed in the vertically extending portion 33 of the terminals 15-18. As a result, the dimension of the connector 1 in the front-rear direction can be reduced as compared with the connector disclosed in, for example, Japanese Unexamined Patent Application Publication No. 2002-200000. That is, in the connector described in Patent Document 1, as shown in FIG. 5 of the document, the crossing portion (inclined portion) of each contact is formed at the portion of the contact extending in the X direction (front-rear direction). ing. In order to shift the terminal portion of the contact from the contact portion in either direction in the Y direction (horizontal direction), the length of the crossing portion must be increased to some extent. The longer the intersection length, the larger the connector in the X direction. For this reason, it is difficult to reduce the dimension of the connector in the front-rear direction of the connector described in Patent Document 1. In contrast, according to the connector 1 of the embodiment of the present invention, the left inclined portion 36 and the right inclined portion 37 are formed in the vertically extending portion 33 of each of the terminals 11 to 18. Therefore, the left inclined portion 36 And even if the right inclined portion 37 is lengthened, the length of the connector 1 in the front-rear direction is not increased.

また、コネクタ１では、第３の端子群Ｇ３において、各端子１９、２０の接続部３２が右方に変位し、各端子２１、２２の接続部３２が左方に変位していることにより、第３の端子群Ｇ３の最左の端子１９の接続部３２の左面と第３の端子群Ｇ３の最右の端子２２の接続部３２の右面との間の距離が縮小している。これにより、第３の端子群Ｇ３を第１の端子群Ｇ１と第２の端子群Ｇ２との間に配置することによるコネクタ１の左右方向の寸法の増加を抑えることができる。 In the connector 1, in the third terminal group G3, the connection portions 32 of the terminals 19 and 20 are displaced rightward, and the connection portions 32 of the terminals 21 and 22 are displaced leftward. The distance between the left surface of the connection portion 32 of the leftmost terminal 19 of the third terminal group G3 and the right surface of the connection portion 32 of the rightmost terminal 22 of the third terminal group G3 is reduced. As a result, it is possible to suppress an increase in the dimension of the connector 1 in the left-right direction due to arranging the third terminal group G3 between the first terminal group G1 and the second terminal group G2.

また、コネクタ１において、第１の端子群Ｇ１の後端側と第２の端子群Ｇ２の後端側との間には第３の端子群Ｇ３の後端側が配置されている。これにより、第１の端子群Ｇ１の後端側と第２の端子群Ｇ２の後端側との間の空間を利用して、低速高速信号の伝送または電源の供給を行うことができる。したがって、二対の高速差動信号および一対の低速差動信号の伝送と電源供給とを一括して行う小型のコネクタを実現することができる。 In the connector 1, the rear end side of the third terminal group G3 is arranged between the rear end side of the first terminal group G1 and the rear end side of the second terminal group G2. As a result, the space between the rear end side of the first terminal group G1 and the rear end side of the second terminal group G2 can be used to transmit low-speed high-speed signals or supply power. Therefore, it is possible to realize a compact connector that collectively performs transmission of two pairs of high-speed differential signals and pair of low-speed differential signals and power supply.

また、コネクタ１においては、嵌合部４３が前方視略台形状に形成され、第１および第２の端子群Ｇ１、Ｇ２の各端子１１～１８の接触部３１が嵌合部４３の下底側に配置され、第３の端子群Ｇ３の各端子１９～２２の接触部３１が嵌合部４３の上底側に配置され、第１の端子群Ｇ１における最左の端子１１の接触部３１が第３の端子群Ｇ３における最左の端子１９の接触部３１よりも左方に位置し、第２の端子群Ｇ２における最右の端子１８の接触部３１が第３の端子群Ｇ３における最右の端子２２の接触部３１よりも右方に位置し、第３の端子群Ｇ３における最左および最右の端子１９、２２の接触部３１の左右方向の寸法が、端子１１～１８、２０、２１のうちのいずれの端子の接触部３１の左右方向の寸法よりも大きい。この構成により、コネクタ同士の誤嵌合を防止可能な形状を有する嵌合部４３に、二対の高速差動信号の伝送および電源の供給等を行うための複数の端子の接触部３１を効率よく、コンパクトに配置することができる。 In the connector 1, the fitting portion 43 is formed in a substantially trapezoidal shape when viewed from the front, and the contact portions 31 of the terminals 11 to 18 of the first and second terminal groups G1 and G2 are located at the bottom of the fitting portion 43. The contact portions 31 of the terminals 19 to 22 of the third terminal group G3 are arranged on the upper bottom side of the fitting portion 43, and the contact portion 31 of the leftmost terminal 11 in the first terminal group G1 is located to the left of the contact portion 31 of the leftmost terminal 19 in the third terminal group G3, and the contact portion 31 of the rightmost terminal 18 in the second terminal group G2 is located farthest in the third terminal group G3. The contact portions 31 of the leftmost and rightmost terminals 19 and 22 in the third terminal group G3 are positioned to the right of the contact portions 31 of the right terminals 22, and the lateral dimensions of the contact portions 31 of the terminals 11 to 18 and 20 , 21 is larger than the lateral dimension of the contact portion 31 of any terminal. With this configuration, the contact portions 31 of a plurality of terminals for transmitting two pairs of high-speed differential signals, supplying power, etc., are efficiently attached to the fitting portion 43 having a shape capable of preventing erroneous fitting of connectors. Can be placed well and compactly.

また、コネクタ１においては、第１および第２の端子群Ｇ１、Ｇ２の各端子１１～１８の接触部３１、および第３の端子群Ｇ３において最左および最右の端子１９、２２を除く各端子２０、２１の接触部３１の左右方向の寸法がそれぞれ等しい。この構成により、コネクタ１の組立時に、各端子１１～１８、２０、２１をハウジング４１に組み入れる際の押圧力を略均一化することができ、コネクタ１の組立作業を簡素化することができる。 In the connector 1, the contact portions 31 of the terminals 11 to 18 of the first and second terminal groups G1 and G2, and the leftmost and rightmost terminals 19 and 22 of the third terminal group G3 are The lateral dimensions of the contact portions 31 of the terminals 20 and 21 are equal. With this configuration, when the connector 1 is assembled, the pressing force applied when the terminals 11 to 18, 20, and 21 are assembled into the housing 41 can be made substantially uniform, and the assembly work of the connector 1 can be simplified.

また、コネクタ１においては、第１および第２の端子群Ｇ１、Ｇ２のそれぞれの端子１１～１８の接触部３１がそれぞれ等しい間隔を置いて配置され、第３の端子群Ｇ３において中央に配置された端子２０、２１の接触部３１が、端子１１～１８の接触部３１の間隔と等しい間隔を置いて配置され、第３の端子群Ｇ３における最左および最右の端子１９、２２のそれぞれの左右方向の寸法が各端子１１～１８の接触部３１の左右方向の寸法の２倍の値に、それぞれの端子１１～１８の接触部３１の間隔の大きさを加えた値と略等しい。この構成により、上下方向に向かい合う端子の位置を揃え、各端子１１～２２を整然と配置することができる。したがって、コネクタ１の組立時において、各端子１１～２２をハウジング４１に組み入れる工程を簡素化することができる。 In the connector 1, the contact portions 31 of the terminals 11 to 18 of the first and second terminal groups G1 and G2 are arranged at equal intervals, and are centrally arranged in the third terminal group G3. The contact portions 31 of the terminals 20 and 21 are arranged at intervals equal to the intervals of the contact portions 31 of the terminals 11 to 18, and the leftmost and rightmost terminals 19 and 22 in the third terminal group G3 are spaced apart from each other. The horizontal dimension is approximately equal to twice the horizontal dimension of the contact portions 31 of the terminals 11 to 18 plus the distance between the contact portions 31 of the terminals 11 to 18 . With this configuration, the positions of the terminals facing each other in the vertical direction can be aligned, and the terminals 11 to 22 can be arranged in order. Therefore, when assembling the connector 1, the process of incorporating the terminals 11 to 22 into the housing 41 can be simplified.

なお、上記実施形態のコネクタ１では、第１および第２の端子群Ｇ１、Ｇ２を嵌合部４３の下段に配置し、第３の端子群Ｇ３を嵌合部４３の上段に配置したが、これらの配置を上下逆にしてもよい。 In the connector 1 of the above embodiment, the first and second terminal groups G1 and G2 are arranged below the fitting portion 43, and the third terminal group G3 is arranged above the fitting portion 43. These arrangements may be turned upside down.

Only the portion 32, only the connection portion 32 of the terminals 13 and 14, or only the connection portion 32 of the terminals 12 to 14 may be displaced leftward. Similarly, instead of displacing the connection portions 32 of all the terminals 15 to 18 of the second terminal group G2 to the right, only the connection portions 32 of the terminal 15, or only the connection portions 32 of the terminals 15 and 16, or Only the connecting portions 32 of the terminals 15 to 17 may be displaced leftward.
