一般に、分電盤内の例えば三相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設けられる配線用遮断器（MCCB：Molded Case Circuit Breaker）の２次側とその配下に接続される電磁開閉器（Electromagnetic Contact）の１次側とを直線的に並べて分電盤内に配置しておいて電線を使って両者を端子接続して接続し、負荷側の電気機器に電気を供給することが知られている。   Generally, the secondary side of a circuit breaker (MCCB) provided in the electrical line on the electrical load side connected under the main circuit breaker of, for example, three-phase 200V in the distribution board The primary side of an electromagnetic switch (Electromagnetic Contact) connected underneath is placed in a distribution board in a straight line, and both terminals are connected using an electric wire to connect them. It is known to supply electricity to equipment.

また、主配線用遮断器において、複数の負荷側の電気ラインに分電するための給電分岐配線には母線バーを備えて、この母線バーは導体金属を板棒状に加工して例えば三相分を所定の間隔空けた状態で前述の負荷側の配線用遮断器の１次側に端子接続されたりするように、機器間を導体金属で加工した導体バーで接続する構成が知られている（例えば、特許文献１参照）。   Further, in the main circuit breaker, a power supply branch wiring for distributing power to a plurality of load-side electrical lines is provided with a bus bar, and the bus bar is formed by processing a conductor metal into a plate bar shape, for example, for a three-phase distribution line. Are connected to each other with a conductor bar processed with a conductive metal so that terminals are connected to the primary side of the load-side circuit breaker described above with a predetermined gap therebetween ( For example, see Patent Document 1).

またその他に、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Ｉ字型の連結銅バーで三相分を一本ずつ独立して接続するための電力導線である導体バーも知られている（例えば、特許文献２参照）。   In addition, a conductor that is a power conductor for independently connecting three-phase components one by one with an I-shaped connecting copper bar to a plurality of branch circuit breakers in a distribution board and a bus bar Bars are also known (see, for example, Patent Document 2).

特開平７−２９８４２６号公報（図２、図３、図４）Japanese Patent Laid-Open No. 7-298426 (FIGS. 2, 3, and 4) 特開２００９−１１０４７号公報（図１、図２、図３）JP 2009-11047 A (FIGS. 1, 2, and 3)

A bent portion 32b bent in a substantially crank shape on the proximal end side of the presser portion 32a, and a holding portion bent from the proximal end side to the distal end side of the bent portion 32b and in contact with the lower surface side of the flat portion 31c of the lower clamping member 31 32c is provided. Note that a through window 32e through which the lower holding member 31 is inserted is provided in the vertical portion 32d of the bent portion 32b of the upper holding member 32 (see FIG. 7A).

また、配線用遮断器１０の接合面部１３と対向する前面すなわち上面８０の前面側垂直面８０ｂに、プラグイン端子金具３０のばね力を解除する解除部材（ドライバやピン等）の挿入孔部８２が設けられている。この挿入孔部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の屈曲部３２ｂを押すことによって母線バー８のプラグ端子８ａの接続が解除されるようになっている。   An insertion hole 82 for a release member (driver, pin, etc.) for releasing the spring force of the plug-in terminal fitting 30 is provided on the front surface facing the joining surface portion 13 of the circuit breaker 10 for wiring, that is, the front surface vertical surface 80b of the upper surface 80. Is provided. The connection of the plug terminal 8a of the bus bar 8 is released by inserting a release member such as a driver or a pin into the insertion hole 82 and pushing the bent portion 32b of the plug-in terminal fitting.

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、それぞれ下端部にクランク状に垂下する板状のプラグ端子８ａを具備している。なお、プラグ端子８ａは必ずしもクランク状に垂下する板状である必要なく、例えばケーブル，棒状端子であってもよい。また、複数の母線バー８は、図３に示すように、合成樹脂製の板状絶縁体８ｂを介在させて水平方向に重ね合わされており、全ての母線バー８は断面略コ字状の合成樹脂製の絶縁カバー８ｃによって上面及び左右両側面が被覆されている。このように、複数の母線バー８間に絶縁体８ｂを介在させて重ね合わせると共に、全ての母線バー８を絶縁カバー８ｃによって上面及び左右両側面を被覆することにより、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。   A 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 are plate-like plug terminals each hanging in a crank shape at the lower end. 8a. The plug terminal 8a does not necessarily have a plate shape that hangs down in a crank shape, and may be, for example, a cable or a rod-shaped terminal. Further, as shown in FIG. 3, the plurality of bus bars 8 are overlapped in the horizontal direction with a synthetic resin plate insulator 8b interposed therebetween, and all the bus bars 8 are combined with a substantially U-shaped cross section. The upper surface and both left and right side surfaces are covered with a resin insulating cover 8c. In this way, the insulator 8b is interposed between the plurality of bus bars 8 so as to overlap each other, and all the bus bars 8 are covered with the insulating cover 8c on the upper surface and both the left and right side surfaces, so that the space insulation distance of the bus bar 8 is increased. Is not required, and a protective structure against electric shock is not required.

このように配線用遮断器１０の上面８０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 of the wiring breaker 10, the structure of the joint surface portion 13 of the wiring breaker 10 can be simplified. After joining the circuit breaker 10 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に接続される電磁開閉器２０について説明する。図４に示すように電磁開閉器２０の前方接合面部２１における下端部側には、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の狭持部材３１，３２間に挿入係合する第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。このプラグ端子部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とを接合する際に、棒端子片２２ａが弾性力に抗してプラグイン端子金具３０の挟持部材３１，３２間に挿入係合されるようになっている。   Next, the electromagnetic switch 20 connected to the wiring breaker described above will be described. As shown in FIG. 4, on the lower end side of the front joint surface portion 21 of the electromagnetic switch 20, an insertion member is interposed between the holding members 31 and 32 of the first plug-in terminal fitting 30 provided in the circuit breaker 10 for wiring. A plug terminal portion 22 which is a first plug terminal portion to be combined is provided. The plug terminal portion 22 has a plate-like bar terminal piece 22a. When the circuit breaker 10 for wiring and the electromagnetic switch 20 are joined, the bar terminal piece 22a is plugged in against the elastic force. It is inserted and engaged between the holding members 31 and 32 of the terminal fitting 30.

また、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状の筒体２２ｂが突設されている。この筒体２２ｂは配線用遮断器１０に設けられたプラグイン端子金具３０を収容凹部１６内に着脱可能に嵌挿されるように形成されており、配線用遮断器１０と電磁開閉器２０が接合された状態で、収容凹部１６内に筒体２２ｂが嵌挿されて、配線用遮断器１０と電磁開閉器２０の接合を強固にしている。   Further, a rectangular cylindrical body 22b that surrounds and protects the plug terminal portion 22 protrudes from the front joint surface portion 21 of the electromagnetic switch 20. The cylindrical body 22b is formed so that the plug-in terminal fitting 30 provided in the wiring circuit breaker 10 is detachably inserted into the housing recess 16, and the wiring circuit breaker 10 and the electromagnetic switch 20 are joined. In this state, the cylindrical body 22b is fitted in the housing recess 16 to strengthen the connection between the circuit breaker 10 for wiring and the electromagnetic switch 20.

この場合、プラグ端子部２２は、電磁開閉器２０内に配設される電磁コイル２３の通電による励磁によって作動する可動接点２４ａと電気的に接続する固定接点２４ｂ，２４ｃの内の一方の固定接点２４ｂに設けられている。他方の固定接点２４ｃは、電磁開閉器２０の背面部すなわち後方接合面部２１Ａに設けられた第２のプラグイン端子部である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に設けられたプラグイン端子金具３０と同様に構成されているので、同一部分には同一符号を付して説明は省略する。また、プラグイン端子金具３０Ｂは、第１のプラグ端子部２２が配置される前方接合面部２１の位置と対向する後方接合面部２１Ａの同一位置に設けられている。なお、プラグイン端子金具３０Ｂのばね力を解除する解除部材（図示せず）の挿入孔部８２が設けられている。この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）参照）。なお、電磁開閉器２０の上面部には電磁コイル２３の端子２５が設けられている。 In this case, the plug terminal portion 22 is one of the fixed contacts 24b and 24c that are electrically connected to the movable contact 24a that is activated by excitation by energization of the electromagnetic coil 23 disposed in the electromagnetic switch 20. 24b. The other fixed contact 24c is connected to a plug-in terminal fitting 30B, which is a second plug-in terminal portion provided on the back surface portion of the electromagnetic switch 20, that is, the rear joint surface portion 21A. Since the second plug-in terminal fitting 30B is configured in the same manner as the plug-in terminal fitting 30 provided in the wiring breaker 10 described above, the same portions are denoted by the same reference numerals and description thereof is omitted. Further, the plug-in terminal fitting 30B is provided at the same position of the rear joint surface portion 21A facing the position of the front joint surface portion 21 where the first plug terminal portion 22 is disposed. An insertion hole 82 for a release member (not shown) that releases the spring force of the plug-in terminal fitting 30B is provided. Terminals or electric wires 60A of other electric devices (not shown) are electrically connected to the plug-in terminal fitting 30B (see FIG. 7B). A terminal 25 of the electromagnetic coil 23 is provided on the upper surface of the electromagnetic switch 20.

このようにプラグイン端子金具３０Ｂをプラグイン端子金具３０と対向する同一位置に配置することにより、電磁開閉器２０内部の構造をシンプル化することができ、電磁開閉器２０の大きさを小さくすることができる。   Thus, by arranging the plug-in terminal fitting 30B at the same position facing the plug-in terminal fitting 30, the structure inside the electromagnetic switch 20 can be simplified, and the size of the electromagnetic switch 20 can be reduced. be able to.

また、図４に示すように、電磁開閉器２０の内部には、電磁開閉器２０が通電された際に電磁コイル２３の励磁によって作動する可動接点２４ａが設けられている。可動接点２４ａは、縦向きに配設された電磁コイル２３の鉄芯２３ａの端部に配置され、電磁開閉器２０に対して垂直方向に移動して固定接点２４ｂ，２４ｃと接続されることで、電磁開閉器２０が通電されるように構成されている。   As shown in FIG. 4, a movable contact 24 a that is activated by excitation of the electromagnetic coil 23 when the electromagnetic switch 20 is energized is provided inside the electromagnetic switch 20. The movable contact 24a is arranged at the end of the iron core 23a of the electromagnetic coil 23 arranged in the vertical direction, moves in the vertical direction with respect to the electromagnetic switch 20, and is connected to the fixed contacts 24b and 24c. The electromagnetic switch 20 is configured to be energized.

このように可動接点２４ａが電磁開閉器２０に対して鉛直方向に移動するので、分電盤内に電気的な問題が生じた場合に、固定接点２４ｂ，２４ｃと可動接点２４ａとの接続を容易に解除することができ、安全性を向上させることができる。   Since the movable contact 24a moves in the vertical direction with respect to the electromagnetic switch 20 in this way, it is easy to connect the fixed contacts 24b, 24c and the movable contact 24a when an electrical problem occurs in the distribution board. It is possible to improve the safety.

また、図５に示すように、配線用遮断器１０の接合面部１３と電磁開閉器２０の前方接合面部２１部における上端部側には、配線用遮断器１０と電磁開閉器２０とを係脱可能に係合（連結）する係止部４１と係止受け部４２とからなる係止部材４０が設けられている。この場合、係止部４１は、例えばばね性を有する鋼板にて形成されており、電磁開閉器２０の前方接合面部２１の上端部に電磁開閉器２０の筐体と同様の材質で一体化、又は溶着される矩形状の固定片４３と、この固定片４３の前辺の両端から前方側に向かって水平に突出する一対の係止片４４と、両係止片４４の先端部に穿設される横長のスリット状係止孔４５とで構成されている。また、係止受け部４２はスリット状係止孔４５より若干小さく形成されると共に、係止部４１と対向する面に傾斜面４６を有する断面略三角形状に形成されており、配線用遮断器１０の上面の接合面部１３部側の左右２箇所に止着されている。   Further, as shown in FIG. 5, the circuit breaker 10 and the electromagnetic switch 20 are engaged and disengaged on the upper end side of the joint surface portion 13 of the circuit breaker 10 and the front joint surface portion 21 of the electromagnetic switch 20. A locking member 40 including a locking portion 41 and a locking receiving portion 42 that can be engaged (connected) is provided. In this case, the locking portion 41 is formed of, for example, a spring steel plate, and is integrated with the upper end portion of the front joint surface portion 21 of the electromagnetic switch 20 with the same material as the casing of the electromagnetic switch 20. Alternatively, a rectangular fixing piece 43 to be welded, a pair of locking pieces 44 protruding horizontally from both ends of the front side of the fixing piece 43 toward the front side, and drilled at the distal ends of both locking pieces 44 And a horizontally long slit-like locking hole 45. Further, the latch receiving portion 42 is formed to be slightly smaller than the slit-like latch hole 45 and is formed in a substantially triangular shape having an inclined surface 46 on the surface facing the latch portion 41, and is a circuit breaker for wiring. 10 are fixed at two left and right positions on the side of the joint surface portion 13 on the upper surface.

このように構成される係止部材４０は、配線用遮断器１０と電磁開閉器２０とを接合する際に、係止部４１の係止片４４が弾性変形して係止受け部４２の傾斜面４６を乗り越えて、スリット状係止孔４５が係止受け部４２に係合することで、いわゆるスナップ係合によって係止部４１のスリット状係止孔４５と係止受け部４２とが係合して配線用遮断器１０と電磁開閉器２０とを接合（連結）する。また、配線用遮断器１０と電磁開閉器２０との接合（連結）を解除する場合は、係止部４１の係止片４４を上方に移動させてスリット状係止孔４５と係止受け部４２との係合を解除することができる。   In the locking member 40 configured in this manner, when the circuit breaker 10 for wiring and the electromagnetic switch 20 are joined, the locking piece 44 of the locking portion 41 is elastically deformed and the locking receiving portion 42 is inclined. The slit-like locking hole 45 engages with the locking receiving portion 42 over the surface 46, so that the slit-like locking hole 45 of the locking portion 41 and the locking receiving portion 42 are engaged by so-called snap engagement. In addition, the circuit breaker 10 for wiring and the electromagnetic switch 20 are joined (connected). Further, when the connection (connection) between the circuit breaker 10 for wiring and the electromagnetic switch 20 is released, the locking piece 44 of the locking portion 41 is moved upward so that the slit-shaped locking hole 45 and the locking receiving portion are moved. The engagement with 42 can be released.

なお、前記説明では、電磁開閉器２０に係止部４１を設け、配線用遮断器１０に係止受け部４２を設けたが、逆にしてもよい。すなわち、配線用遮断器１０の接合面部１３部の上端部に係止部４１を設け、電磁開閉器２０の前方接合面部２１の上端部に係止受け部４２を設けてもよい。また、係止部材４０を配線用遮断器１０と電磁開閉器２０の接合面部１３，２１部の上下端部の両方に設けてもよい。これにより、配線用遮断器１０と電磁開閉器２０の接合（連結）を更に強固にすることができる。   In addition, in the said description, although the latching | locking part 41 was provided in the electromagnetic switch 20, and the latching receiving part 42 was provided in the circuit breaker 10 for wiring, you may make it reverse. That is, the locking portion 41 may be provided at the upper end portion of the joint surface portion 13 of the circuit breaker 10 for wiring, and the locking receiving portion 42 may be provided at the upper end portion of the front joint surface portion 21 of the electromagnetic switch 20.
