Description

本発明は、分岐コネクタに関し、より詳細には、本線ケーブル（主ケーブル）に対して分岐ケーブルを電気的に分岐接続するための分岐コネクタに関する。 The present invention relates to a branch connector, and more particularly to a branch connector for electrically branching and connecting a branch cable to a main line cable (main cable).

工場の生産ラインにおいて、ロボット、工作機械等の各種生産機器を集中管理するために設けられるＦＡ（ＦａｃｔｏｒｙＡｕｔｏｍａｔｉｏｎ）ネットワークにおいては、マスタユニットと称されるネットワーク全体を統轄する機器と複数の周辺機器とを通信ケーブルを介して信号を伝送可能に接続し、マスタユニットと当該複数の周辺機器との間で周辺機器を制御するための信号の送受信が行われている。上記のようなＦＡネットワークにおいては、特許文献１にも記載されているように、マスタユニットから延びる通信ケーブルにスレーブモジュールと称される機器が複数接続され、さらに、このスレーブモジュールに、ロボット、工作機械等におけるロボットコントローラ、スイッチ、センサ、ランプ、バルブ等の周辺機器が接続されることで、当該スレーブモジュールを介して各種周辺機器の制御が行われるように構築されている。 In the FA (Factory Automation) network provided for centralized management of various production equipment such as robots and machine tools in the factory production line, a master unit and a plurality of peripheral equipment Are transmitted via a communication cable so that signals can be transmitted and received between the master unit and the plurality of peripheral devices. In the FA network as described above, as described in Patent Document 1, a plurality of devices called slave modules are connected to a communication cable extending from a master unit. By connecting peripheral devices such as robot controllers, switches, sensors, lamps, bulbs and the like in machines, various peripheral devices are controlled through the slave module.

上記のようなＦＡネットワークにおいて使用される、電源の供給を行うための電源供給ケーブルや信号の送受信を行うための通信ケーブルは、例えば、図８に示すようなＡＳ−ｉケーブルと称されるようなものがある。図８に示すように、ＡＳ−ｉケーブル（以下、「ケーブル５０」という。）は、底辺側の長さが短い全体として断面非対称の略台形の段付き形状をなしている。ケーブル５０は、その内部にいずれも断面円形の導体５１および導体５２が設けられて極性を有している。正の直流電圧が供給される導体５１は、絶縁体５３によってその周囲が同心円状に被覆されている。一方、負の直流電圧が供給される導体５２も同様にして、絶縁体５４によってその周囲が被覆されている。そして、絶縁体５３，５４に被覆された導体５１，５２は略台形の絶縁性を有するシース５５によって略平行に並んだ状態に保持されている。このようなケーブル５０の非対称な段付き形状により、ケーブル５０の極性を誤ることなく所定の機器に取り付けることができる。 A power supply cable for supplying power and a communication cable for transmitting and receiving signals used in the FA network as described above are referred to as, for example, an AS-i cable as shown in FIG. There is something. As shown in FIG. 8, the AS-i cable (hereinafter referred to as “cable 50”) has a substantially trapezoidal stepped shape with an asymmetric cross section as a whole having a short bottom side. The cable 50 is provided with a conductor 51 and a conductor 52 each having a circular cross section, and has a polarity. The conductor 51 to which a positive DC voltage is supplied is covered with an insulator 53 concentrically around the periphery. On the other hand, the conductor 52 to which a negative DC voltage is supplied is similarly covered with an insulator 54. The conductors 51 and 52 covered with the insulators 53 and 54 are held in a substantially parallel state by a sheath 55 having a substantially trapezoidal insulating property. Due to the asymmetric stepped shape of the cable 50, the cable 50 can be attached to a predetermined device without mistaken polarity.

上記のような断面非対称の形状からなるケーブル５０のスレーブモジュールへの電気的な接続の一例を図８に示している。図示のように、ケーブル５０を受容可能なスレーブモジュール９０の受容部９１に、スレーブモジュール９０，９０´によって挟持されるような状態にケーブル５０が受容される。スレーブモジュール９０´からは、先端に尖鋭な圧接部が形成された２本の圧接端子３５，３６（圧接ピン）が下方に突出している。ケーブル５０を挟持するスレーブモジュール９０，９０´がねじ９２，９２によって締結されるときには、これら圧接端子３５，３６がスレーブモジュール９０，９０´により押圧されて、シース５５および絶縁体５３，５４を通してそれぞれ導体５１，５２内に挿入される。このとき、圧接端子３５および３６が、各々導体５１および５２に当接して接続され、スレーブモジュール９０，９０´内部と導体５１，５２が圧接端子３５，３６を介して導通される。このように、ケーブル５０のスレーブモジュール９０への電気的な接続は、スレーブモジュール９０，９０´のねじ止めにより簡単に行うことが可能である。また、圧接端子３５，３６が圧接接続された後は、シース５５および絶縁体５３，５４の弾力により、圧接端子３５，３６によって空けられた穴が閉塞するので、ケーブル５０の絶縁性が保持される。
特開２００１−９２５１７号公報 FIG. 8 shows an example of electrical connection of the cable 50 having an asymmetric cross section as described above to the slave module. As shown in the figure, the cable 50 is received in a state where it is sandwiched by the slave modules 90 and 90 ′ in the receiving portion 91 of the slave module 90 that can receive the cable 50. From the slave module 90 ′, two press contact terminals 35 and 36 (press contact pins) each having a sharp press contact portion formed at the tip protrude downward. When the slave modules 90 and 90 ′ holding the cable 50 are fastened by the screws 92 and 92, the press contact terminals 35 and 36 are pressed by the slave modules 90 and 90 ′ and are passed through the sheath 55 and the insulators 53 and 54, respectively. It is inserted into the conductors 51 and 52. At this time, the press contact terminals 35 and 36 are in contact with and connected to the conductors 51 and 52, respectively, and the inside of the slave modules 90 and 90 'and the conductors 51 and 52 are conducted through the press contact terminals 35 and 36. Thus, the electrical connection of the cable 50 to the slave module 90 can be easily performed by screwing the slave modules 90 and 90 '. In addition, after the press contact terminals 35 and 36 are press connected, the holes formed by the press contact terminals 35 and 36 are closed by the elasticity of the sheath 55 and the insulators 53 and 54, so that the insulation of the cable 50 is maintained.

ところで、上記のようなケーブル５０に別のケーブル６０を分岐させるようにして接続させる分岐接続は、従来では、例えば図９に示すようなケーブル５０およびケーブル６０の各々の絶縁被覆５３，５４および６３，６４をケーブルの端面から一部取り除いて導体５１，５２および６１，６２を露出させた上で、露出した導体５１および導体６１同士と、導体５２および導体６２同士を各々半田付けして接続させる（結線部を斜線で示す）方法により行われていたため、ケーブルを分岐接続させる作業が面倒であった。また、上述したようにケーブル５０（ケーブル６０）は、極性を有しているために２本の導体のうち、同じ極性の導体同士を接続させなければならないが、上記のように導体を露出させて半田付けして接続させる方法によると、作業の煩わしさから異なる極性の導体同士を誤って接続させる可能性があった。 By the way, conventionally, the branch connection in which another cable 60 is branched to the cable 50 as described above is conventionally performed by, for example, the insulation coatings 53, 54 and 63 of the cable 50 and the cable 60 as shown in FIG. , 64 are partially removed from the end face of the cable to expose the conductors 51, 52 and 61, 62, and then the exposed conductor 51 and the conductor 61 are connected to each other by soldering the conductor 52 and the conductor 62 to each other. Since it was performed by the method (the connection portion is indicated by diagonal lines), the work of branching the cables was troublesome. Moreover, since the cable 50 (cable 60) has polarity as described above, it is necessary to connect conductors of the same polarity among the two conductors, but the conductor is exposed as described above. According to the method of soldering and connecting, there is a possibility that conductors of different polarities are erroneously connected due to the troublesome work.

以上のような問題に鑑みて、本発明では簡単にしかも接続方法を誤ることなくケーブルの分岐接続をさせることのできる分岐コネクタを提供することを目的とする。 In view of the problems as described above, it is an object of the present invention to provide a branch connector that can make a branch connection of a cable easily and without erroneous connection.

When the cover block 20 is attached to the base block 10, the inner surfaces of the engaging legs 23, 23 are guided along the inclined locking surfaces formed on the front surfaces of the locking protrusions 13, 13. Since the engaging leg portions 23, 23 move downward while spreading in the left-right direction of the cover block 20, the engaging leg portions 23, 23 can be smoothly engaged with the locking projections 13, 13.

カバーブロック２０がベースブロック１０に取り付けられると、カバーブロック２０から露出している圧接端子３１および圧接端子３２の尖鋭な両端部３１ａ，３１ｂ，３２ａ，３２ｂは、各々絶縁体５３，６３，５４，６４内に挿入される。この状態では、カバーブロック２０をベースブロック１０に被せる際に受ける押圧力により、圧接部３１ａが主ケーブル５０内の第１導体５１に当接し、同様に押圧力を受ける圧接部３２ａが主ケーブル５０内の第２導体５２に当接する。一方、圧接部３１ｂが分岐ケーブル６０の第１導体６１に当接し、圧接部３２ｂが分岐ケーブル６０内の第２導体６２に当接する。この状態で、圧接ねじ８１，８１（図４参照）をカバーブロック２０の圧接ねじ取付孔２２，２２に挿通させた上で、さらにベースブロック１０の孔１２，１２に挿通させて各々を図示しないナットで螺合させ、カバーブロック２０とベースブロック１０とを締結させる。このようにして、主ケーブル５０の第１導体５１と分岐ケーブル６０の第１導体６１とが圧接端子３１を介して、また、主ケーブル５０の第２導体５２と分岐ケーブル６０の第２導体６２とが圧接端子３２を介して接続され、主ケーブル５０の第１導体５１と主ケーブル５０に対して左方に分岐された分岐ケーブル６０の第１導体６１とが、また、主ケーブル５０の第２導体５２と分岐ケーブル６０の第２導体６２とがそれぞれ導通可能となる。 When the cover block 20 is attached to the base block 10, the sharp end portions 31 a, 31 b, 32 a, and 32 b of the press contact terminal 31 and the press contact terminal 32 that are exposed from the cover block 20 are made of the insulators 53, 63, 54, respectively. 64. In this state, the pressure contact portion 31a abuts on the first conductor 51 in the main cable 50 due to the pressing force applied when the cover block 20 is put on the base block 10, and the pressure contact portion 32a receiving the pressing force is similarly connected to the main cable 50. It contacts the second conductor 52 inside. On the other hand, the press contact portion 31 b contacts the first conductor 61 of the branch cable 60, and the press contact portion 32 b contacts the second conductor 62 in the branch cable 60. In this state, the pressure contact screws 81 and 81 (see FIG. 4) are inserted into the pressure contact screw mounting holes 22 and 22 of the cover block 20 and further inserted into the holes 12 and 12 of the base block 10, respectively. The cover block 20 and the base block 10 are fastened by screwing with a nut. In this way, the first conductor 51 of the main cable 50 and the first conductor 61 of the branch cable 60 are connected via the press contact terminal 31, and the second conductor 52 of the main cable 50 and the second conductor 62 of the branch cable 60. Are connected via the pressure contact terminal 32, and the first conductor 51 of the main cable 50 and the first conductor 61 of the branch cable 60 branched to the left with respect to the main cable 50 are also connected to the first conductor 61 of the main cable 50. The two conductors 52 and the second conductor 62 of the branch cable 60 can be electrically connected to each other.

以上の説明では、本発明に係るコネクタ１を用いて主ケーブル５０に対して主ケーブル５０の第１導体５１の側に分岐ケーブルを分岐接続させる（主ケーブル５０に対して左方に分岐させる）場合について説明したが、コネクタ１を用いて主ケーブル５０に対して主ケーブル５０の第２導体５２の側に分岐ケーブルを分岐接続させる（主ケーブル５０に対して右方に分岐させる）ことも可能である。このような場合には、図５に示すように、左方に分岐させた場合と同様の形状を有するベースブロック１０と、一対のＬ字形の右方分岐用圧接端子３１´，３２´からなる圧接端子３０´（例えばピアス端子）と、当該右方分岐用の圧接端子３１´，３２´を取付可能なようなＬ字形の圧接端子固定穴２５´，２６´が設けられた右方分岐用のカバーブロック２０´と、主ケーブル５０から右方に分岐されるように分岐ケーブル７０を分岐接続させることを意味する「Ｒ」という表示が描かれている端子カバー４０´とを使用する。 In the above description, the branch cable is branched and connected to the main cable 50 on the first conductor 51 side using the connector 1 according to the present invention (branched to the left with respect to the main cable 50). Although the case has been described, it is also possible to branch and connect the branch cable to the second conductor 52 side of the main cable 50 with respect to the main cable 50 using the connector 1 (branch to the right with respect to the main cable 50). It is. In such a case, as shown in FIG. 5, the base block 10 having the same shape as that branched to the left side and a pair of L-shaped right branching press contact terminals 31 ′ and 32 ′ are formed. For right branching provided with L-shaped pressure contact terminal fixing holes 25 ', 26' to which the pressure contact terminal 30 '(for example, a pierce terminal) and the right branch pressure contact terminals 31', 32 'can be attached. Cover block 20 'and terminal cover 40' on which "R" indicating that the branch cable 70 is branched and connected so as to branch rightward from the main cable 50 are used.

図６の上段には、上記のような構造のコネクタ１により主ケーブル５０とこの主ケーブル５０に対して左方に分岐させた状態に接続させた分岐ケーブル６０とを模式的に示している。一方、主ケーブル５０に対して分岐ケーブル６０を右方に分岐接続させるため、コネクタ１の前後の向きを変えて主ケーブル５０および分岐ケーブル６０をコネクタ１に取り付けると、図６の中段に示す図のようになる。この状態では、分岐ケーブル６０の第１導体６１と主ケーブル５０の第２導体５２とが接続され、分岐ケーブル６０の第２導体６２と主ケーブル５０の第１導体５１とが接続されて、極性が入れ替わって異なる極性同士が接続されてしまう。 The upper part of FIG. 6 schematically shows the main cable 50 and the branch cable 60 connected to the left side of the main cable 50 by the connector 1 having the above structure. On the other hand, when the main cable 50 and the branch cable 60 are attached to the connector 1 by changing the front-rear direction of the connector 1 in order to branch-connect the branch cable 60 to the right with respect to the main cable 50, the diagram shown in the middle stage of FIG. become that way. In this state, the first conductor 61 of the branch cable 60 and the second conductor 52 of the main cable 50 are connected, the second conductor 62 of the branch cable 60 and the first conductor 51 of the main cable 50 are connected, and the polarity Are switched and different polarities are connected.

これを解決するため、上述したように圧接端子３１，３２とは向きの異なった形状の右分岐用の圧接端子３１´，３２´を備えたコネクタ１´を用いて、主ケーブル５０に対して右方に分岐させた状態に分岐ケーブル７０を接続させた様子を図６の下段に示す。この図に示すように、右分岐用のコネクタ１´を用いれば、右方分岐用の分岐ケーブル７０の第１導体７１と主ケーブル５０の第１導体７１とが接続され、分岐ケーブル７０の第２導体７２と主ケーブル５０の第２導体５２とが接続されて、極性が入れ替わることなく正しく分岐ケーブル７０を接続させることができる。 In order to solve this problem, as described above, the connector 1 ′ having the right branch pressure contact terminals 31 ′ and 32 ′ having a shape different from the direction of the pressure contact terminals 31 and 32 is used. A state where the branch cable 70 is connected in a state branched to the right is shown in the lower part of FIG. As shown in this figure, when the right branch connector 1 ′ is used, the first conductor 71 of the branch cable 70 for right branch and the first conductor 71 of the main cable 50 are connected, and the first conductor 71 of the branch cable 70 is connected. The two conductors 72 and the second conductor 52 of the main cable 50 are connected, and the branch cable 70 can be correctly connected without changing the polarity.

具体的には図５に示すように、端子カバー取付部２４´の底面には、左方分岐用のカバーブロック２０とは異なり、コネクタ１の前後の方向に対して圧接端子取付穴２５，２６とは対称的にカバーブロック２０´の右方側にＬ字型に延びる圧接端子取付穴２５´，２６´が設けられている。圧接端子３１´，３２´も、この圧接端子取付穴２５´，２６´に各々嵌挿可能なように各々Ｌ字形に延びている。そして、このような形状の圧接端子３１´，３２´を各々カバーブロック２０´の圧接端子取付穴２５´，２６´に挿入して、端子カバー４０´を端子カバー取付部２４´に装着する。 Specifically, as shown in FIG. 5, unlike the left branch cover block 20, the bottom surface of the terminal cover mounting portion 24 ′ has pressure contact terminal mounting holes 25, 26 in the front-rear direction of the connector 1. In contrast, pressure contact terminal mounting holes 25 ′ and 26 ′ extending in an L shape are provided on the right side of the cover block 20 ′. The press contact terminals 31 ′ and 32 ′ also extend in an L shape so that they can be inserted into the press contact terminal mounting holes 25 ′ and 26 ′, respectively. Then, the press contact terminals 31 ′ and 32 ′ having such shapes are respectively inserted into the press contact terminal mounting holes 25 ′ and 26 ′ of the cover block 20 ′, and the terminal cover 40 ′ is mounted on the terminal cover mounting portion 24 ′.

そして、主ケーブル５０をベースブロック１０の主ケーブル取付溝１４に受容させ、分岐ケーブル７０を分岐ケーブル取付溝１５´に受容させる。この状態で、カバーブロック２０´をベースブロック１０に被せて、カバーブロック２０´をベースブロック１０に固着させる。このとき、圧接部３１ａ´がカバーブロック２０´に押圧されて主ケーブル５０内の第１導体５１に当接し、圧接部３２ａ´が主ケーブル５０内の第２導体５２に当接する。一方、圧接部３１ｂ´がカバーブロック２０´に押圧されて分岐ケーブル７０の第１導体７１に当接し、圧接部３２ｂ´が分岐ケーブル７０内の第２導体７２に当接する。このようにして、主ケーブル５０の第１導体５１と分岐ケーブル７０の第１導体７１とが圧接端子３１´を介して、また、主ケーブル５０の第２導体５２と分岐ケーブル７０の第２導体７２とが圧接端子３２´を介して接続され、主ケーブル５０の第１導体５１と主ケーブル５０に対して右方に分岐された分岐ケーブル７０の第１導体７１とが、また、主ケーブル５０の第２導体５２と分岐ケーブル７０の第２導体７２とがそれぞれ導通可能となる。 The main cable 50 is received in the main cable mounting groove 14 of the base block 10, and the branch cable 70 is received in the branch cable mounting groove 15 '. In this state, the cover block 20 ′ is put on the base block 10, and the cover block 20 ′ is fixed to the base block 10. At this time, the pressure contact portion 31 a ′ is pressed by the cover block 20 ′ and comes into contact with the first conductor 51 in the main cable 50, and the pressure contact portion 32 a ′ comes into contact with the second conductor 52 in the main cable 50. On the other hand, the pressure contact portion 31 b ′ is pressed by the cover block 20 ′ and comes into contact with the first conductor 71 of the branch cable 70, and the pressure contact portion 32 b ′ comes into contact with the second conductor 72 in the branch cable 70. In this way, the first conductor 51 of the main cable 50 and the first conductor 71 of the branch cable 70 are connected via the press-contact terminal 31 ′, and the second conductor 52 of the main cable 50 and the second conductor of the branch cable 70. 72 is connected via a pressure contact terminal 32 ′, and the first conductor 51 of the main cable 50 and the first conductor 71 of the branch cable 70 branched rightward with respect to the main cable 50 are also connected to the main cable 50. The second conductor 52 and the second conductor 72 of the branch cable 70 can be electrically connected to each other.

なお、本発明の範囲は必ずしも上述した実施形態に限定されるものではない。例えば、第２実施形態として、図７の模式図に示すようにしてコネクタ１の圧接端子３３，３４（例えばピアス端子）を構成することもできる。このような場合においては、カバーブロックをベースブロックに被せたときにカバーブロックにより圧接端子３３および圧接端子３４が押圧されると、圧接端子３３先端部の圧接部３３ａが分岐ケーブル６０内の第１導体６１に、圧接部３３ｂが分岐ケーブル７０内の第１導体７１に当接する。一方、圧接端子３４先端部の圧接部３４ａが分岐ケーブル６０の第２導体６２に、圧接部３４ｂが分岐ケーブル７０内の第２導体７２に当接する。このようにして、分岐ケーブル６０の第１導体６１および分岐ケーブル７０の第１導体７１が圧接端子３３介して接続され、分岐ケーブル６０の第２導体６２および分岐ケーブル７０の第２導体７２が圧接端子３４を介して接続されて、分岐ケーブル６０と分岐ケーブル７０とを主ケーブル５０を跨ぐようにして導通接続（いわゆる十字接続）させることができる。 Note that the scope of the present invention is not necessarily limited to the above-described embodiment. For example, as the second embodiment, the press contact terminals 33 and 34 (for example, pierce terminals) of the connector 1 can be configured as shown in the schematic diagram of FIG. In such a case, when the pressure contact terminal 33 and the pressure contact terminal 34 are pressed by the cover block when the cover block is put on the base block, the pressure contact portion 33a at the tip end of the pressure contact terminal 33 becomes the first in the branch cable 60. The pressure contact portion 33 b abuts on the conductor 61 and the first conductor 71 in the branch cable 70. On the other hand, the press contact portion 34 a at the tip end of the press contact terminal 34 contacts the second conductor 62 of the branch cable 60, and the press contact portion 34 b contacts the second conductor 72 in the branch cable 70. In this way, the first conductor 61 of the branch cable 60 and the first conductor 71 of the branch cable 70 are connected via the press-contact terminal 33, and the second conductor 62 of the branch cable 60 and the second conductor 72 of the branch cable 70 are press-contacted. Connected via the terminal 34, the branch cable 60 and the branch cable 70 can be connected to each other so as to straddle the main cable 50 (so-called cross connection).
