Description

分岐配線システムBranch wiring system
　本発明は、配線用遮断器とこれに電気的に接続される電磁開閉器等の電気機器とを備えた分岐配線システムに関するものである。 The present invention relates to a branch wiring system including a circuit breaker for wiring and an electric device such as an electromagnetic switch electrically connected thereto.
　一般に、分電盤内の三相２００Ｖの主配線用遮断器の配下に接続される電気的負荷側の電気ラインにおいて、配線用遮断器（MCCB：Molded　Case　Circuit　Breaker）とその配下の電磁開閉器（Electromagnetic　Contact）とを直線的に並べて、配線用遮断器の二次側端子と電磁開閉器の一次側端子とを電線を使って接続し、負荷側の電気機器に電気を供給することが行われている。 Generally, in the electrical line on the electrical load side connected to the 3-phase 200V main circuit breaker in the distribution board, the circuit breaker (MCCB: Molded Case Circuit Breaker) and its electromagnetic switch (Electromagnetic Contact) are arranged in a straight line, and the secondary side terminal of the circuit breaker and the primary side terminal of the electromagnetic switch are connected using electric wires to supply electricity to the load side electrical equipment. It has been broken.
　特開平７－２９８４２６号公報（文献１）には（図２、図３、図４を参照）、三相用の主配線用遮断器と給電バーとを接続する３本の渡りバーを、曲げ加工した導体金属板により形成することが開示されている。 Japanese Patent Laid-Open No. 7-298426 (reference 1) (see FIGS. 2, 3, and 4) discloses that three transition bars connecting a three-phase main circuit breaker and a power feeding bar are bent. It is disclosed that the conductive metal plate is processed.
　特開２００９－１１０４７号公報（文献２）には（図１、図２、図３を参照）、分電盤内の複数の分岐用の配線用遮断器と母線バーとを、３本のＩ字型の連結銅バーで三相の各相を個別に接続することが開示されている。 In JP 2009-11047 A (reference 2) (see FIGS. 1, 2 and 3), a plurality of branch circuit breakers and a bus bar in a distribution board are provided with three I It is disclosed that each phase of the three phases is individually connected with a letter-shaped connecting copper bar.
　上記文献１、２などからもわかるように、主配線用遮断器とその配下の分岐配線用の遮断器までの接続にはいわゆる「母線バー」が用いられている。しかし分岐配線用の遮断器とその配下の電気機器（例えば電磁開閉器）とは、多くの場合電線を用いて接続される。分岐配線用の遮断器およびその配下の電気機器が多数有る場合、あるいは分電盤のサイズが小さい場合には、電線による配線接続の作業が面倒である。また、配線が複雑となるため、配線ミスを招く懸念がある。 As can be seen from the documents 1 and 2 above, so-called “busbars” are used for connection between the main circuit breaker and the branch circuit breaker under it. However, the circuit breaker for branch wiring and the electrical equipment (for example, electromagnetic switch) under the branch circuit are often connected using electric wires. When there are a large number of circuit breakers for branch wiring and electric devices thereunder, or when the size of the distribution board is small, the work of wiring connection by electric wires is troublesome. Further, since the wiring becomes complicated, there is a concern of causing a wiring mistake.
　また、分岐配線用の遮断器及びその配下の電気機器の数が多い場合には、分岐配線用の遮断器及び電気機器の取り付け面積も多く必要であり、分電盤の設置面積及び費用の増加に繋がる。 In addition, when there are a large number of branch circuit breakers and electrical devices under the branch circuit breaker, it is necessary to provide a large area for installing branch circuit breakers and electrical devices.

　図５から図７に示すように、配線用遮断器１０の後方接合面部１３の下端部（図示例では後方接合面部１３の窪みの下端部）の複数箇所例えば３箇所に、互いに水平方向に平行な矩形の凹部１６が設けられている。各凹部１６内にプラグイン端子金具３０が収容されている。プラグイン端子金具３０は、一対の挟持部材３１、３２を具備しており、挟持部材３１、３２がバネ力によりその間に挿入されたプラグ端子部２２を保持する。図７（ａ）に示すように、下側に位置する下部挟持部材３１は、外方先端部に下方に屈曲する傾斜面部３１ａと、傾斜面部３１ａの基端に連なる波形部３１ｂと、波形部３１ｂの基端に連なる平坦部３１ｃとを有している。上側に位置する上部挟持部材３２は、その外方先端部に略半円筒状の押え部３２ａと、押え部３２ａの基端に連なるクランク形の屈曲部３２ｂと、屈曲部３２ｂの基端に連なり先端側に延びる平坦な保持部３２ｃとを有している。保持部３２ｃは下部挟持部材３１の平坦部３１ｃに当接して平坦部３１ｃを支持している。上部挟持部材３２の屈曲部３２ｂの垂直部３２ｄには窓３２ｅが設けられており、窓３２ｅを下部挟持部材３１が貫通している。 As shown in FIG. 5 to FIG. 7, a plurality of, for example, three places on the lower end portion of the rear joint surface portion 13 of the circuit breaker 10 for wiring (the lower end portion of the recess of the rear joint surface portion 13 in the illustrated example) are parallel to each other in the horizontal direction. A rectangular recess 16 is provided. A plug-in terminal fitting 30 is accommodated in each recess 16. The plug-in terminal fitting 30 includes a pair of clamping members 31 and 32, and the clamping members 31 and 32 hold the plug terminal portion 22 inserted between them by a spring force. As shown in FIG. 7A, the lower holding member 31 located on the lower side includes an inclined surface portion 31a bent downward at the outer distal end portion, a corrugated portion 31b connected to the base end of the inclined surface portion 31a, and a corrugated portion.

The upper clamping member 32 located on the upper side is connected to the substantially semi-cylindrical presser portion 32a at the outer distal end thereof, the crank-shaped bent portion 32b connected to the base end of the presser portion 32a, and the base end of the bent portion 32b. And a flat holding portion 32c extending to the distal end side. The holding part 32c is in contact with the flat part 31c of the lower clamping member 31 and supports the flat part 31c. A window 32e is provided in the vertical portion 32d of the bent portion 32b of the upper clamping member 32, and the lower clamping member 31 passes through the window 32e.
　配線用遮断器１０の後方接合面部１３と反対側の前面、具体的には配線用遮断器１０の上面に８０に段差を形成する前面側垂直面８０ｂに、挿入孔部８２が形成されている。挿入孔部８２にドライバやピン等の解除部材を挿入してプラグイン端子金具３０Ａの屈曲部３２ｂを押すことによって、プラグイン端子金具３０Ａのバネ力による母線バー８のプラグ端子８ａの保持を解除することができる。 An insertion hole portion 82 is formed on the front surface of the wiring breaker 10 opposite to the rear joining surface portion 13, specifically, on the front vertical surface 80 b that forms a step on the upper surface of the wiring breaker 10. . By inserting a release member such as a screwdriver or a pin into the insertion hole 82 and pushing the bent portion 32b of the plug-in terminal fitting 30A, the holding of the plug terminal 8a of the bus bar 8 by the spring force of the plug-in terminal fitting 30A is released. can do.
　なお、配線用遮断器１０の上面８０に配設されたプラグイン端子金具３０Ａに接続される複数（例えば３枚）の母線バー８はそれぞれ、逆Ｌ字形の板状のプラグ端子８ａを具備しており、プラグ端子８ａの先端部は垂直に下方に延びている。プラグ端子８ａの形態はこれに限定されるものではなく、例えばケーブル又は棒状端子であってもよい。図３に示すように、水平方向に延びる複数の母線バー８が上下に積層されており、上下方向に隣接する母線バー８同士の間には合成樹脂製の板状絶縁体８ｂが介在している。母線バー８と板状絶縁体８ｂとからなる積層体の上面及び左右両面は、断面略コ字（角括弧）形の合成樹脂製の絶縁カバー８ｃによって被覆されている。このように、母線バー８間に絶縁体８ｂを介在させて重ね合わせると共に、絶縁カバー８ｃによる被覆を行うことにより、母線バー８の空間絶縁距離の確保が不要となり、感電に対する保護構造が不要となる。 The plurality of (for example, three) bus bars 8 connected to the plug-in terminal fittings 30A disposed on the upper surface 80 of the wiring breaker 10 each have an inverted L-shaped plate-like plug terminal 8a. The tip of the plug terminal 8a extends vertically downward. The form of the plug terminal 8a is not limited to this, and may be, for example, a cable or a rod-shaped terminal. As shown in FIG. 3, a plurality of bus bars 8 extending in the horizontal direction are stacked one above the other, and a plate-like insulator 8b made of synthetic resin is interposed between the bus bars 8 adjacent in the vertical direction. Yes. The upper surface and the left and right surfaces of the laminate composed of the bus bar 8 and the plate-like insulator 8b are covered with a synthetic resin insulating cover 8c having a substantially U-shaped cross section. As described above, the insulator 8b is interposed between the bus bars 8 and they are overlapped, and by covering with the insulating cover 8c, it is not necessary to secure the space insulation distance of the bus bars 8, and no protection structure against electric shock is required. Become.
　このように配線用遮断器１０の上面８０側に母線バー用のプラグイン端子金具３０Ａを配設することにより、配線用遮断器１０の接合面部１３の構造をシンプル化することができ、また、配線用遮断器１０と電磁開閉器２０とを接合した後に、配線用遮断器１０に母線バー８を接続することができる。 Thus, by arranging the plug-in terminal fitting 30A for the bus bar on the upper surface 80 side of the circuit breaker 10 for wiring, the structure of the joint surface portion 13 of the circuit breaker 10 for wiring can be simplified. After joining the circuit breaker 10 for wiring and the electromagnetic switch 20, the bus bar 8 can be connected to the circuit breaker 10 for wiring.
　次に、上述した配線用遮断器１０に接続される電磁開閉器２０について説明する。図４及び図５に示すように、電磁開閉器２０の前方接合面部２１の下端部には、第１のプラグ端子部であるプラグ端子部２２が設けられている。プラグ端子部２２は板状の棒端子片２２ａを有しており、配線用遮断器１０と電磁開閉器２０とを連結する際に、棒端子片２２ａが、配線用遮断器１０に設けられた第１のプラグイン端子金具３０の挟持部材３１、３２間に弾性力に抗して挿入される。 Next, the electromagnetic switch 20 connected to the wiring breaker 10 described above will be described.

The first plug-in terminal fitting 30 is inserted between the clamping members 31 and 32 against the elastic force.
　図５に示すように、電磁開閉器２０の前方接合面部２１には、プラグ端子部２２を包囲して保護する矩形の筒体２２ｂが突設されている。電磁開閉器２０を配線用遮断器１０に連結するとき、配線用遮断器１０の後方接合面部１３に形成されたプラグイン端子金具３０を収容している収容凹部１６に、筒体２２ｂが嵌挿される。これにより配線用遮断器１０と電磁開閉器２０の接合が強固になる。 As shown in FIG. 5, a rectangular cylindrical body 22 b that surrounds and protects the plug terminal portion 22 protrudes from the front joint surface portion 21 of the electromagnetic switch 20. When the electromagnetic switch 20 is connected to the wiring circuit breaker 10, the cylindrical body 22 b is inserted into the housing recess 16 that houses the plug-in terminal fitting 30 formed on the rear joint surface portion 13 of the wiring circuit breaker 10. It is. Thereby, joining of the circuit breaker 10 for wiring and the electromagnetic switch 20 becomes firm.
　図４に示すように、電磁開閉器２０内には電磁コイル２３が配設されており、電磁コイル２３を通電（励磁）すると、可動接点２４ａ、２４ａが固定接点２４ｂ，２４ｃに電気的に接続されるようになっている。プラグ端子部２２は、一方の固定接点２４ｂに接続されている。電磁開閉器２０の背面部すなわち後方接合面部２１Ａには、第２のプラグイン端子部であるプラグイン端子金具３０Ｂが設けられている。他方の固定接点２４ｂは、プラグイン端子金具３０Ｂに接続されている。第２のプラグイン端子金具３０Ｂは、上述した配線用遮断器１０のプラグイン端子金具３０と同じ構成を有しており（図７（ａ）、（ｂ）を比較参照）、同一部分に同一符号を付して重複説明は省略する。プラグイン端子金具３０Ｂは、プラグ端子部２２が配置される前方接合面部２１と反対側の後方接合面部２１Ａの同一位置（同じ高さ位置、同じ横方向位置）に設けられている。プラグイン端子金具３０Ｂに他の電気機器（図示せず）の端子又は電線６０Ａが電気的に接続される（図７（ｂ）を参照）。電磁開閉器２０の筐体の上面には電磁コイル２３の端子２５が設けられている。また、図６に示すように、電磁開閉器２０の筐体の底面には、プラグイン端子金具３０Ｂのバネ力による電線６０Ａの保持を解除するために解除部材（図示せず）を挿入するための挿入孔部８２が設けられている。この挿入孔部８２は、配線用遮断器１０の前面側垂直面８０ｂの挿入孔部８２と同じ役割を果たす。 As shown in FIG. 4, an electromagnetic coil 23 is disposed in the electromagnetic switch 20, and when the electromagnetic coil 23 is energized (excited), the movable contacts 24a and 24a are electrically connected to the fixed contacts 24b and 24c.
