Description

本発明は伝送ケーブル、特に、差動伝送ケーブルおよびそれを接続する伝送ケーブル用コネクタに関する。   The present invention relates to a transmission cable, and more particularly to a differential transmission cable and a transmission cable connector for connecting the same.

従来、高速信号を伝送する伝送ケーブルとしては、高速信号線の両側にグランド線を平行に並設することにより、電磁ノイズおよびクロストークノイズの影響を抑制している（特許文献１参照）。このため、差動伝送を行う場合も、図６に概略的に図示した伝送ケーブルのように、基材１の上面に平行に並設した一対のグランド線２，２の間に、プラス線３およびマイナス線４を平行に並設するとともに、前記基材１の裏面に形成したグランド層５にバンプ６を介して前記グランド線２，２を接続することにより、ノイズの影響を効果的に抑制している（非特許文献１参照）。

For this reason, even in the case of performing differential transmission, a plus wire 3 is interposed between a pair of ground wires 2 and 2 arranged in parallel to the upper surface of the substrate 1, as in the transmission cable schematically shown in FIG. In addition, the negative wires 4 are juxtaposed in parallel, and the ground wires 2 and 2 are connected to the ground layer 5 formed on the back surface of the substrate 1 via the bumps 6 to effectively suppress the influence of noise. (See Non-Patent Document 1).

しかしながら、前述のような伝送ケーブルでは、グランド配線の巾寸法だけ大きな実装スペースが必要となり、装置の小型化に限界がある。また、前記伝送ケーブルでは、その生産工数が多いだけでなく、前記伝送ケーブルに接続するコネクタの接続端子が多くなり、前記コネクタの部品点数，組立工数および接続工数が多くなるという問題点がある。   However, the transmission cable as described above requires a large mounting space by the width of the ground wiring, and there is a limit to downsizing the device. In addition, the transmission cable not only has a large number of production man-hours, but also has a problem that the number of connection terminals of the connector connected to the transmission cable increases, and the number of parts, assembly man-hours, and connection man-hours of the connector increase.

本発明は、前記問題点に鑑み、小型で実装スペースが小さく、かつ、生産工数が少ない伝送ケーブル、さらに、部品点数、組立工数および接続工数が少ない伝送ケーブル用コネクタを提供することを課題とする。   The present invention has been made in view of the above problems, and it is an object of the present invention to provide a transmission cable that is small in size, has a small mounting space, and has a small number of production steps, and further a transmission cable connector that has a small number of parts, assembly steps, and connection steps. .

本発明にかかる伝送ケーブルは、前記課題を解決すべく、基板の表裏面に上方伝送線および下方伝送線をそれぞれ複数本ずつ並設するとともに、上下で対となるように千鳥状に配置した構成としてある。   The transmission cable according to the present invention has a configuration in which a plurality of upper transmission lines and a plurality of lower transmission lines are arranged in parallel on the front and back surfaces of the substrate, and are arranged in a staggered manner so as to be paired in the upper and lower sides, in order to solve the above-described problem. It is as.

本発明によれば、上下で対となるように上方，下方伝送線を配置してあるので、対とならない隣り合う伝送配線との距離が長くなり、グランド線を設ける必要がない。このため、グランド線の巾寸法だけ小さくでき、実装スペースを節約でき、装置の小型化が可能となるとともに、伝送ケーブルの生産工数が少なくなり、生産コストを低減できる。また、本願発明にかかる伝送ケーブルを接続するためのコネクタもグランド線に接続する接続端子が不要となるので、部品点数、組立工数および接続工数が少なくなる。   According to the present invention, since the upper and lower transmission lines are arranged so as to form a pair in the upper and lower directions, the distance between adjacent transmission lines that are not paired becomes long, and it is not necessary to provide a ground line. For this reason, only the width dimension of the ground wire can be reduced, the mounting space can be saved, the apparatus can be downsized, the number of transmission cable production steps can be reduced, and the production cost can be reduced. In addition, since the connector for connecting the transmission cable according to the present invention does not require a connection terminal for connecting to the ground wire, the number of parts, the number of assembly steps, and the number of connection steps are reduced.

本発明にかかる実施形態としては、上下で対となるように配置した伝送線の水平間距離が、上下で対とならない隣り合う配線間の水平間距離よりも短くしてもよい。
本実施形態によれば、対となる伝送線の水平間距離を短くすることにより、対となる上方伝送線と下方伝送線との結合が強くなる。このため、上方伝送線および下方伝送線に対するノイズの影響にバラツキがあっても、上方伝送線および下方伝送線に対するノイズが均等化され、ノイズの差分にかかる分解能が高まるので、ノイズによる弊害をより一層抑制できる。 As an embodiment according to the present invention, the horizontal distance between the transmission lines arranged in pairs at the top and bottom may be shorter than the horizontal distance between adjacent wirings that are not paired at the top and bottom.
According to the present embodiment, by shortening the horizontal distance between the paired transmission lines, the coupling between the paired upper transmission line and the lower transmission line is strengthened. For this reason, even if the influence of noise on the upper transmission line and the lower transmission line varies, the noise on the upper transmission line and the lower transmission line is equalized and the resolution of the noise difference is increased. It can be further suppressed.

また、本発明にかかる伝送ケーブルに接続するコネクタとしては、伝送ケーブルの上方伝送線および下方伝送線にそれぞれ接続可能な第１接点および第２接点を有する接続端子を、コネクタ本体に所定のピッチで並設した構成としてある。   In addition, as a connector to be connected to the transmission cable according to the present invention, a connection terminal having a first contact and a second contact that can be connected to the upper transmission line and the lower transmission line of the transmission cable, respectively, at a predetermined pitch on the connector body. The configuration is arranged side by side.

本発明によれば、上方伝送線および下方伝送線を同一形状の接続端子で接続できるので、１つの製造金型で対応できるとともに、部品管理が容易になる。   According to the present invention, the upper transmission line and the lower transmission line can be connected with the same shape of the connection terminals, so that it can be handled with a single manufacturing mold and the parts management is facilitated.

本発明にかかる実施形態としては、接続端子の第１接点から接続端部までの沿面距離と、前記接続端子の第２接点から接続端部までの沿面距離とが同一であってもよい。
本実施形態によれば、差動伝送を行った場合におけるプラス信号の伝送時間とマイナス信号の伝送時間とが等しくなり、時間差がなくなる。この結果、ノイズキャンセル効果が高まり、伝送信号の信頼性が向上するという効果がある。 As an embodiment according to the present invention, the creepage distance from the first contact of the connection terminal to the connection end may be the same as the creepage distance from the second contact of the connection terminal to the connection end.
According to the present embodiment, the transmission time of the plus signal and the transmission time of the minus signal are equal when differential transmission is performed, and there is no time difference. As a result, the noise canceling effect is enhanced, and the reliability of the transmission signal is improved.

本発明にかかる実施形態を図１ないし図５の添付図面に従って説明する。
すなわち、本実施形態にかかる伝送ケーブル１０は、コネクタ２０，２０を介してプリント基板５０に接続されている。 Embodiments according to the present invention will be described with reference to the accompanying drawings of FIGS.
That is, the transmission cable 10 according to the present embodiment is connected to the printed circuit board 50 via the connectors 20 and 20.

前記伝送ケーブル１０は、図３に示すように、フレキシブルな帯状シート１０ａの表裏面に上方伝送線１１ａ，１１ｂ，１１ｃおよび下方伝送線１２ａ，１２ｂ，１２ｃをそれぞれ３本ずつ並設するとともに、上下で千鳥状となるように配置することにより、３対のペア配線を設けてある。   As shown in FIG. 3, the transmission cable 10 has three upper transmission lines 11a, 11b, 11c and three lower transmission lines 12a, 12b, 12c arranged in parallel on the front and back surfaces of a flexible belt-like sheet 10a. By arranging in a zigzag pattern, three pairs of wiring lines are provided.

前記コネクタ２０は、図１に示すように、コネクタ本体２１と、前記コネクタ本体２１に所定のピッチで圧入され、前記伝送ケーブル１０の上方，下方伝送線１１ａ〜１１ｃ，１２ａ〜１２ｃにそれぞれ接続可能な接続端子３０と、前記コネクタ本体２１に回動可能に取り付けられる操作レバー４０と、から構成されている。   As shown in FIG. 1, the connector 20 is press-fitted into the connector main body 21 and the connector main body 21 at a predetermined pitch, and can be connected to the upper and lower transmission lines 11a to 11c and 12a to 12c of the transmission cable 10, respectively. And a control lever 40 rotatably attached to the connector main body 21.

前記コネクタ本体２１は、図４に示すように、一方側から伝送ケーブル１０を挿入可能な開口部を有する一方、他方側から複数本の接続端子３０を所定のピッチで挿入，固定するとともに、操作レバー４０を回動可能に組み付けてある。ただし、本実施形態において、操作レバー４０を回動可能に支持し、かつ、脱落を防止するため、前記コネクタ本体２１の両側から一対の弾性腕部（図示せず）が延在している。   As shown in FIG. 4, the connector main body 21 has an opening into which the transmission cable 10 can be inserted from one side, and a plurality of connection terminals 30 are inserted and fixed at a predetermined pitch from the other side. The lever 40 is assembled so as to be rotatable. However, in this embodiment, a pair of elastic arm portions (not shown) extend from both sides of the connector main body 21 in order to rotatably support the operation lever 40 and to prevent the operation lever 40 from falling off.

前記接続端子３０は、図５Ｂに示すように、操作レバー４０を回動可能に支持する挿入支持部３１と、前記挿入支持部３１の水平先端部に位置する回動中心３２から上方側に延在する略Ｔ字形の可動接点片３３と、前記回動中心３２から下方側に延在する係合用固定接点片３４とから構成されている。前記挿入支持部３１は、その上面縁部に後述する操作レバー４０の突条４１を支持する支持凹部３１ａを設けてある。また、前記可動接点片３３は、一方側の水平方向に延在した先端部を可動接点３３ａとする一方、他方側の水平方向に延在した操作腕部３３ｂを有している。さらに、前記係合用固定接点片３４は、上下に分かれた上，下係合舌片３４ａ，３４ｂを前記コネクタ本体２１の係合用舌片２２に係合して抜け止めされるとともに、前記上係合舌片３４ａの上端部を固定接点３４ｃとしてある。   As shown in FIG. 5B, the connection terminal 30 extends upward from an insertion support portion 31 that rotatably supports the operation lever 40 and a rotation center 32 that is positioned at the horizontal tip of the insertion support portion 31. An approximately T-shaped movable contact piece 33 and an engaging fixed contact piece 34 extending downward from the rotation center 32 are formed. The insertion support portion 31 is provided with a support concave portion 31a for supporting a protrusion 41 of the operation lever 40, which will be described later, on an upper surface edge portion thereof. In addition, the movable contact piece 33 has a movable contact 33a having a tip portion extending in the horizontal direction on one side, and an operating arm portion 33b extending in the horizontal direction on the other side. Further, the engaging fixed contact piece 34 is divided into upper and lower parts, and the lower engaging tongue pieces 34a and 34b are engaged with the engaging tongue pieces 22 of the connector main body 21 to be prevented from coming off. The upper end portion of the tongue piece 34a is a fixed contact 34c.

本実施形態では、接続端子３０の回動中心３２から前記可動接点３３ａまでの沿面距離と、前記回動中心３２から固定接点３４ｃまでの沿面距離とは等しい。このため、差動伝送を行った場合におけるプラス信号の伝送時間とマイナス信号の伝送時間とが等しくなり、時間差がなくなる。この結果、ノイズキャンセル効果が高まり、伝送信号の信頼性が向上する。   In the present embodiment, the creepage distance from the rotation center 32 of the connection terminal 30 to the movable contact 33a is equal to the creepage distance from the rotation center 32 to the fixed contact 34c. For this reason, the transmission time of the plus signal and the transmission time of the minus signal are equal when differential transmission is performed, and the time difference is eliminated. As a result, the noise canceling effect is enhanced and the reliability of the transmission signal is improved.

前記操作レバー４０は、その両側を、前記コネクタ本体２１の両側から側方に延在した一対の弾性腕部（図示せず）に回動可能に支持されている。このため、図１および図５Ｂに示すように、接続端子３０の支持凹部３１ａを支点として操作レバー４０を倒して回動させると、その下端部に設けた突条４１を支点として操作レバー４０が回動する。この結果、てこの原理で操作レバー４０の操作爪部４２が可動接点片３３の操作腕部３３ｂの先端部を押し上げ、前記回動中心３２を支点として可動接点片３３が傾く。そして、可動接点３３ａが伝送ケーブル１０の上方伝送線１１ａ，１１ｂ，１１ｃの一端部に圧接するとともに、接続端子３０の固定接点３４ｃが伝送ケーブルの下方伝送線１２ａ，１２ｂ，１２ｃの一端部にそれぞれ圧接する。これにより、３対のペア配線が形成される。   The operation lever 40 is rotatably supported at its both sides by a pair of elastic arm portions (not shown) extending laterally from both sides of the connector main body 21. For this reason, as shown in FIGS. 1 and 5B, when the operation lever 40 is tilted and rotated with the support recess 31a of the connection terminal 30 as a fulcrum, the operation lever 40 has the ridge 41 provided at the lower end thereof as a fulcrum. Rotate. As a result, on the principle of lever, the operation claw portion 42 of the operation lever 40 pushes up the distal end portion of the operation arm portion 33b of the movable contact piece 33, and the movable contact piece 33 tilts with the rotation center 32 as a fulcrum. The movable contact 33a is in pressure contact with one end of the upper transmission lines 11a, 11b, 11c of the transmission cable 10, and the fixed contact 34c of the connection terminal 30 is respectively connected to one end of the lower transmission lines 12a, 12b, 12c of the transmission cable. Press contact. Thereby, three pairs of pair wirings are formed.

前記プリント基板５０は、図１に示すように、所定のピッチで並設した接続パッド５１にコネクタ２０の接続端子３０をそれぞれ接続固定することにより、前記コネクタ２０を電気接続してある。   As shown in FIG. 1, the printed circuit board 50 is electrically connected to the connector 20 by connecting and fixing the connection terminals 30 of the connector 20 to connection pads 51 arranged in parallel at a predetermined pitch.

次に、前述の構成部品の接続方法について説明する。
まず、操作レバー４０を引き起こしてあるコネクタ本体２１の挿入口から伝送ケーブル１０の一端側を挿入して位置決めする。そして、前記操作レバー４０を倒すことにより、操作レバー４０の突条４１を支点として操作レバー４０を回動させる。このため、操作爪部４２が接続端子３０の操作腕部３３ｂの先端部をてこの原理で押し上げる。この結果、可動接点片３３の一端部に位置する固定接点３３ａが伝送ケーブル１０の上方伝送線１１ａ，１１ｂ，１１ｃの一端部にそれぞれ圧接するとともに、係合用固定接点片３４の固定接点３４ｃが伝送ケーブル１０の下方伝送線１２ａ，１２ｂ，１２ｃの一端部にそれぞれ圧接する。 Next, a method for connecting the above-described components will be described.
First, one end side of the transmission cable 10 is inserted and positioned from the insertion port of the connector main body 21 that causes the operation lever 40. Then, by tilting the operation lever 40, the operation lever 40 is rotated with the ridge 41 of the operation lever 40 as a fulcrum. For this reason, the operation claw portion 42 pushes up the tip end portion of the operation arm portion 33b of the connection terminal 30 on this principle. As a result, the fixed contact 33a positioned at one end of the movable contact piece 33 is in pressure contact with one end of the upper transmission lines 11a, 11b, and 11c of the transmission cable 10, and the fixed contact 34c of the engaging fixed contact piece 34 is transmitted. Each of the lower transmission lines 12a, 12b, and 12c of the cable 10 is in pressure contact with each other.

本実施形態によれば、グランド配線を設ける必要がなくなるとともに、ペアとなる伝送線同士の水平間距離、例えば、上方伝送線１１ａと下方伝送線１２ａとの水平間距離を、ペアとならない隣り合う伝送線同士の水平距離、例えば、上方伝送線１１ａと下方伝送線１２ｂとの水平間距離よりも小さくできる。このため、伝送ケーブル１０を小型化できるだけでなく、グランド配線の製造および接続作業をも省略できるという利点がある。   According to the present embodiment, it is not necessary to provide a ground wiring, and the horizontal distance between the paired transmission lines, for example, the horizontal distance between the upper transmission line 11a and the lower transmission line 12a is not adjacent to each other. The horizontal distance between the transmission lines, for example, the horizontal distance between the upper transmission line 11a and the lower transmission line 12b can be made smaller. For this reason, there is an advantage that not only the transmission cable 10 can be miniaturized, but also the production and connection work of the ground wiring can be omitted.

特に、本実施形態によれば、ペアとなる上方伝送線と下方伝送線とをより一層近づけることができる。このため、ペアとなるプラス信号およびマイナス信号の結合を高めることができ、伝送信号の漏れがより一層少なくなるという利点がある。   In particular, according to the present embodiment, the upper transmission line and the lower transmission line that are paired can be made closer to each other. For this reason, it is possible to increase the coupling of the plus signal and the minus signal that form a pair, and there is an advantage that transmission signal leakage is further reduced.

本願発明にかかる伝送ケーブルは、差動伝送だけでなく、他の高速信号伝送にも適用できる。   The transmission cable according to the present invention can be applied not only to differential transmission but also to other high-speed signal transmission.
