例えば特許文献1及び特許文献2のように、母線側に、回路遮断器の端子と接続する母線を選択的に切替える切替装置を設けたものがある。
As an example of selectively connecting the circuit breaker terminal device and the busbar,
For example, as in Patent Literature 1 and Patent Literature 2, there is a device in which a switching device that selectively switches a bus connected to a terminal of a circuit breaker is provided on the bus.

特許文献1においては、図12に示したように、主電路を形成するブスバー(特許文献1の符号1、2、3)と、回路遮断器の端子に接続されるブスバーの足部(特許文献1の符号101、301、601等)の間に、切替装置を設けて構成している。この切替装置は、該切替装置を構成する接続バー(特許文献1の符号6)に設けられた長穴(特許文献1の符号602)と切替片(特許文献1の符号8)の穴部に共に貫通させた切替ネジ(特許文献1の符号7)の位置を前記長穴の一端もしくは他端に移動させて導通させる導体を選択し回路遮断器の端子に接続される導体を切替えて、回路遮断器に供給する電圧を変更するものである。 In Patent Document 1, as shown in FIG. 12, bus bars (reference numerals 1, 2, and 3 in Patent Document 1) forming a main electric circuit and bus bar feet connected to terminals of a circuit breaker (Patent Document 1) 1 is provided with a switching device between the reference numerals 101, 301, 601 and the like.

The voltage supplied to the circuit breaker is changed.

特許文献2においては、図13に示したように、特許文献1と同じく、主電路を形成するブスバー(特許文献2の符号11、12、13)と、回路遮断器の端子に接続されるブスバーの接続部(特許文献2の符号1301、2001等)の間に、切替装置を設けて構成している。そして切替装置を構成する送り板(特許文献2の符号20)に設けられた長穴部と筒状導体子(特許文献2の符号18)に共に貫通させたねじ(特許文献2の符号17)の位置を前記長穴の一端もしくは他端に移動させて導通させる導体を選択し回路遮断器の端子に接続されるブスバーを切替えて、回路遮断器に供給する電圧を変更するものである。 In Patent Document 2, as shown in FIG. 13, as in Patent Document 1, a bus bar (reference numerals 11, 12, and 13 in Patent Document 2) that forms a main electric circuit and a bus bar connected to a terminal of a circuit breaker Between the connecting portions (reference numerals 1301, 2001, etc. of Patent Document 2).

上述した、母線側に、回路遮断器の端子と接続する母線を選択的に切替える切替装置を設けたものにあっては、次に示したような課題がある。切替装置における切替部を模式的に示した図14を参照して説明するが、切替の状態を表す長穴の部分に位置するねじ頭に着目すると、(a)については、それぞれのねじ頭の並びが規則的であり、回路遮断器に外部の導体のうちどの導体が接続されているのかが一見して把握できる。ここで、一部分の導体について接続を切替えた場合を示した(b)については、図中右側に位置するねじ頭の並び方が左側や中央部分の他のねじ頭の並び方とは変わっており、並び具合を見ることで、選択されている導体が変わっていることが把握できる。ところが、多くの導体について接続を切替えた場合を示した(c)については、ねじ頭の並び方がまちまちで全体的に不規則となり、回路遮断器にどの導体が接続されているのかが非常に把握しづらいものとなる。 In the case where the above-described switching device that selectively switches the bus connected to the terminal of the circuit breaker is provided on the bus side, there are the following problems. The switching unit in the switching device will be described with reference to FIG. 14 schematically showing, but when attention is paid to the screw heads located in the slot portions representing the switching state, (a) The arrangement is regular and it is possible to grasp at a glance which of the external conductors is connected to the circuit breaker. Here, with respect to (b) showing the case where the connection is switched for a part of the conductors, the way of arranging the screw heads located on the right side in the figure is different from the way of arranging the other screw heads on the left side and the central part. By looking at the condition, it can be understood that the selected conductor has changed. However, for (c), which shows the case where connections are switched for many conductors, the arrangement of the screw heads varies widely and overall is irregular, and it is very clear which conductor is connected to the circuit breaker. It will be difficult.

このため、接続する外部の導体のうち、一部分の導体のみ接続を変更した場合には、どの導体を回路遮断器に接続しているのかは容易に把握できるが、接続を変更した導体の数が増えてくると、一転して把握が難しくなり、作業をする者にとっては、接続を行うときや接続後に確認を行う場合において誤解が生じやすくなるおそれがあった。また、回路遮断器に供給される電圧を把握することも容易には行いにくく、回路遮断器に誤った導体を選択して接続した場合には負荷側の電路に不用な電圧が供給されることになり、その場合には負荷側の配線や電気機器に損傷が生じてしまうおそれがある。また、多数のねじの切替を要することから作業性の改善が望まれている。 For this reason, when only a part of the external conductors to be connected is changed, it is easy to determine which conductor is connected to the circuit breaker, but the number of conductors whose connection has been changed As the number increases, it becomes difficult to grasp, and there is a possibility that misunderstandings are likely to occur for those who work, when making a connection or checking after connection. In addition, it is difficult to grasp the voltage supplied to the circuit breaker easily, and when a wrong conductor is selected and connected to the circuit breaker, an unnecessary voltage is supplied to the load-side circuit. In such a case, there is a risk of damage to the load-side wiring and electrical equipment. Further, since it is necessary to switch a large number of screws, improvement in workability is desired.

一方、電圧を変更するときに、切り替えのためのねじを緩めて切替え装置を移動させるときに、ブスバーの足部101、301、ブスバーの接続部2001、1601は回路遮断器に接続されているままなので、不要な力が加えられると、回路遮断器の端子にも力が加わり、端子の緩みや破損、電気的な不良が生ずるおそれがある。 On the other hand, when changing the voltage, when the switching device is moved by loosening the switching screw, the bus bar feet 101 and 301 and the bus bar connection parts 2001 and 1601 remain connected to the circuit breaker. Therefore, if an unnecessary force is applied, a force is also applied to the terminal of the circuit breaker, and there is a risk that the terminal is loosened or damaged, or an electrical failure occurs.

そこで、本発明は、上記問題に鑑みてなされたもので、
回路遮断器における端子装置により母線を選択的に接続する場合や、前記端子装置と母線を接続した後であっても、複数の回路遮断器に対して、どの回路遮断器がどの母線を選択して接続しているのかを回路遮断器の前面側から直接的に把握しやすく、
さらに、接続状態を切替える際に工具を不要として作業性の向上が望め、
回路遮断器に選択的に印加される電圧が端子装置の位置に応じて明確に把握できて、
さらに、回路遮断器の端子部にブスバーの足部や接続部が接続された状態では電圧の変更が行えず、端子部の電気的な不良が発生しにくく、
作業をする者にとって接続母線や供給電圧の誤認を生じさせにくい選択式端子装置を有した回路遮断器の端子構造を提供することを目的とする。
Therefore, the present invention has been made in view of the above problems,
Even when the busbar is selectively connected by the terminal device in the circuit breaker or after the busbar is connected to the terminal device, which circuit breaker selects which bus for the multiple circuit breakers. It is easy to grasp directly from the front side of the circuit breaker,
Furthermore, when switching the connection state, no tools are required and workability can be improved.
The voltage selectively applied to the circuit breaker can be clearly grasped according to the position of the terminal device,
In addition, the voltage of the bus bar cannot be changed in the state where the bus bar foot or the connection part is connected to the terminal part of the circuit breaker, and electrical failure of the terminal part is less likely to occur.
It is an object of the present invention to provide a terminal structure for a circuit breaker having a selective terminal device that is unlikely to cause misidentification of a connection bus or supply voltage for a worker.

本発明に係る回路遮断器の端子構造は、上述の課題を解決すべく構成されたもので、回路遮断器の器体に、分電盤の母線から電気を受電する電源側端子のうち一方の電源側端子について母線との接続位置が可変とされ分電盤の各相の母線のうち所定の母線を選択して接続する可動電源側端子と、母線と電源側端子とが接続されることにより前記分電盤において印加され得る複数の電源電圧を予め表示した電圧表示部とを備えるとともに、前記可動電源側端子と連動される連動部材と係合され、前記可動電源側端子の接続位置の移動に伴って、前記電圧表示部のうち、前記所定の母線と可動電源側端子の接続時において実際には印加されない電源電圧の表示を隠蔽する隠し板とを備え、前記回路遮断器を分電盤から取り外した状態で、前記可動電源側端子を一方の接続位置から他方の接続位置に移動させることに伴い前記隠し板が連動し、前記可動電源側端子の一方の接続位置および他方の接続位置は、回路遮断器の並設方向を器体の幅方向としたとき、該幅方向の一端および他端に設けられ、該可動電源側端子と連動する隠し板が、該可動電源側端子が前記一端に位置するときは前記他端に位置する一方、該可動電源側端子が前記他端に位置するときは前記一端に位置して、前記電圧表示部における所定の母線から回路遮断器に実際に印加される電圧の表示が外部から視認可能に露出することを特徴とした回路遮断器の端子構造を構成するとよい。 The terminal structure of the circuit breaker according to the present invention is configured to solve the above-described problems, and one of the power supply side terminals for receiving electricity from the busbar of the distribution board is provided to the body of the circuit breaker. By connecting the power supply side terminal to the movable power supply side terminal, the position of connection between the power supply side terminal and the busbar is variable, and a predetermined power supply bus is selected from the buses of each phase of the distribution board. A voltage display unit that displays in advance a plurality of power supply voltages that can be applied in the distribution board, and is engaged with an interlocking member that is interlocked with the movable power supply side terminal to move the connection position of the movable power supply side terminal And a concealing plate for concealing the display of the power supply voltage that is not actually applied when the predetermined bus bar and the movable power supply side terminal are connected in the voltage display section. In a state where it is removed from As the source side terminal is moved from one connection position to the other connection position, the hidden plate is interlocked, and one connection position and the other connection position of the movable power supply side terminal are arranged in parallel with each other. Is a width direction of the container body, the hidden plate provided at one end and the other end in the width direction and interlocking with the movable power supply side terminal is the other end when the movable power supply side terminal is located at the one end. On the other hand, when the movable power supply side terminal is located at the other end, the terminal is located at the one end, and the display of the voltage actually applied to the circuit breaker from the predetermined bus in the voltage display unit is externally displayed. A circuit breaker terminal structure may be configured to be exposed so as to be visible.

かかる構成によれば、前記可動電源側端子の移動に伴って隠し板が連動し、可動電源側端子の位置に応じて実際にどの母線が選択されているのか、また、印加される電圧の表示が外部から直接視認可能になるため、作業者にとっては、回路遮断器が接続される母線や供給される電圧値の確認を行いやすい回路遮断器の端子構造を提供できる。 According to this configuration, the hidden plate is interlocked with the movement of the movable power supply side terminal, which bus is actually selected according to the position of the movable power supply side terminal, and the indication of the applied voltage is displayed. Therefore, it is possible to provide a terminal structure for a circuit breaker that makes it easy for an operator to check the busbar to which the circuit breaker is connected and the voltage value to be supplied.

また、前記器体の幅方向の全面に亘って電圧表示部を形成できて、供給電圧を外部から確認するときに視認性が向上できるため、表示される電圧値がより明確に把握しやすい回路遮断器の端子構造を提供できる。 In addition, since a voltage display part can be formed over the entire surface in the width direction of the container and visibility can be improved when the supply voltage is confirmed from the outside, a circuit that makes it easier to grasp the displayed voltage value more clearly A circuit breaker terminal structure can be provided.

以上の如く、本発明によれば、回路遮断器における端子装置により母線を選択的に接続する場合や、前記端子装置と母線を接続した後であっても、複数の回路遮断器に対して、どの回路遮断器がどの母線を選択して接続しているのかを回路遮断器の前面側から直接的に把握しやすく、さらに、接続状態を切替える際に工具を不要として作業性の向上が望め、回路遮断器に選択的に印加される電圧が端子装置の位置に応じて明確に把握できて、さらに、回路遮断器の端子部にブスバーの足部や接続部が接続された状態では電圧の変更が行えず、端子部の電気的な不良が発生しにくく、作業をする者にとって接続母線や供給電圧の誤認を生じさせにくい選択式端子装置を有した回路遮断器の端子構造を提供することができる。 As described above, according to the present invention, even when the busbar is selectively connected by the terminal device in the circuit breaker, or even after the terminal device and the busbar are connected, for the plurality of circuit breakers, It is easy to grasp directly from the front side of the circuit breaker which circuit breaker is selected and which busbar is connected, and further, it is possible to improve workability by eliminating the need for tools when switching the connection state, The voltage selectively applied to the circuit breaker can be clearly grasped according to the position of the terminal device, and the voltage can be changed in the state where the bus bar foot and connection are connected to the terminal of the circuit breaker.

(隠し板の構造)
次に、可動電源側端子部102Bと連動される連動部材と係合され、前記可動電源側端子の接続位置の移動に伴って、前記電圧表示部のうち、前記所定の母線と可動電源側端子の接続時において実際には印加されない電源電圧の表示を隠蔽する隠し板105について説明を行う。
(Hidden board structure)
Next, the predetermined bus and the movable power source side terminal of the voltage display unit are engaged with the interlocking member interlocked with the movable power source side terminal portion 102B, and the connection position of the movable power source side terminal is moved. The hidden plate 105 that hides the display of the power supply voltage that is not actually applied at the time of connection will be described.

隠し板105は、前記器体の前面側に設けられ、該隠し板105の背面側に電圧表示部107が位置する。該隠し板105は、器体の幅方向における長さの略半分の大きさに形成された長四角形状のベースと、該ベースの背面側に設けられた複数の歯を設けたラック105bとを備えている。ラック105bは、ベースに形成した長形状のリブ105b1の端部に、該リブ105b1よりも幅広状に形成されており、該リブ105b1を器体に設けられた開口部101b3に嵌め込み取付けた際に、幅方向に移動させるためのガイド部として働くとともに、前記ラック105bが前面側への抜止めとして働く。 The hidden plate 105 is provided on the front side of the container, and the voltage display unit 107 is located on the back side of the hidden plate 105. The concealing plate 105 includes a long rectangular base formed to be approximately half the length in the width direction of the container, and a rack 105b provided with a plurality of teeth provided on the back side of the base. I have. The rack 105b is formed wider at the end of the long rib 105b1 formed on the base than the rib 105b1, and when the rib 105b1 is fitted into the opening 101b3 provided in the container body, the rack 105b is mounted. The rack 105b functions as a guide for moving in the width direction, and the rack 105b serves as a retaining member to the front side.

前記隠し板105は、後述するピニオン106により、可動電源側端子部102Bの移動と連動して、器体の幅方向における一方の側面寄りと、他方の側面寄りの2箇所の間で連続的に往復移動を行う。そして、それぞれの一方の側面寄りの位置、及び他方の側面寄りの位置において、前記ベースにより、該ベースの背面となる部分に位置する電圧表示部107、即ち、可動電源側端子部102Bが位置しない側における器体の前面a側に設けられた電圧表示部107を隠蔽する。前述のベースの背面となる部分に位置する電圧表示部は、該ベースに隠蔽されて前面側からは視認できず、ベースに隠蔽されない部分に位置する電圧表示部は前面側から視認可能となる。隠蔽される側の電圧値は、実際には印加されない電圧値で、外部に露出する電圧値は実際に印加される電圧値である。 The concealing plate 105 is continuously connected between two positions near the one side surface and the other side surface in the width direction of the body in conjunction with the movement of the movable power supply side terminal portion 102B by the pinion 106 described later. Move back and forth. Then, at each of the positions near one side surface and the other side surface, the voltage display unit 107, that is, the movable power supply side terminal unit 102B located on the back surface of the base is not positioned by the base. The voltage display unit 107 provided on the front surface a side of the container on the side is concealed. The voltage display unit located on the back surface of the base is hidden by the base and cannot be seen from the front side, and the voltage display unit located on the portion not hidden by the base is visible from the front side. The voltage value on the concealed side is a voltage value that is not actually applied, and the voltage value exposed to the outside is a voltage value that is actually applied.

次に、可動電源側端子部102Bと隠し板105とを連動させるピニオン106について説明を行う。
該ピニオン106は、軸106aの周囲に複数の歯を設けて形成されている。該歯は、前記隠し板105に設けられたラック105b、並びに前記可動電源側端子部102Bに設けられたラック102B1と噛み合うように、隠し板105に設けられたラック105bと前記可動電源側端子部102Bに設けられたラック102B1との間に位置するよう配設される。前記ピニオン106は、回路遮断器の器体の前面寄りに、該器体の一部を凹ませて形成した軸受部101dに軸106aが枢支されて配設される。
Next, the pinion 106 that links the movable power supply side terminal portion 102B and the hidden plate 105 will be described.
The pinion 106 is formed by providing a plurality of teeth around the shaft 106a. The teeth are engaged with the rack 105b provided on the hidden plate 105 and the rack 105b provided on the hidden plate 105 so as to mesh with the rack 102B1 provided on the movable power supply side terminal portion 102B. It arrange | positions so that it may be located between racks 102B1 provided in 102B. The pinion 106 is disposed near the front surface of the body of the circuit breaker, with a shaft 106a pivotally supported by a bearing portion 101d formed by recessing a part of the body.

図7に、これら隠し板105とピニオン106と可動電源側端子部102Bとの器体への配置状態を一部断面にて示した。
図7のように、隠し板105と可動電源側端子部102bとの間にピニオン106が配置され、それぞれのラック105b、102B1と、器体により枢支された軸106aが回動することにより、可動電源側端子部102Bを一方の接続位置から他方の接続位置に移動させることに伴い、前記隠し板105が連動する。より詳しくは、該可動電源側端子120Bと連動する隠し板105が、該可動電源側端子102Bが前記一端に位置するときは前記他端に位置する一方、該可動電源側端子102Bが前記他端に位置するときは前記一端に位置し、前記幅方向において、可動電源側端子102Bを移動させる方向とは反対の方向に隠し板105が移動する。
FIG. 7 shows a partial cross-sectional view of the arrangement of the hidden plate 105, the pinion 106, and the movable power supply side terminal portion 102B in the container.
As shown in FIG. 7, the pinion 106 is arranged between the hidden plate 105 and the movable power supply side terminal portion 102b, and the racks 105b and 102B1 and the shaft 106a pivotally supported by the container body are rotated. As the movable power supply terminal portion 102B is moved from one connection position to the other connection position, the hidden plate 105 is interlocked. More specifically, the hidden plate 105 linked to the movable power supply side terminal 120B is located at the other end when the movable power supply side terminal 102B is located at the one end, while the movable power supply side terminal 102B is located at the other end. Is located at the one end, and the hidden plate 105 moves in the direction opposite to the direction in which the movable power supply side terminal 102B is moved in the width direction.

器体の幅方向における両端の周縁部には、前記隠し板105がいずれかの端部に位置したときに当接する壁部101b10、101a10が、器体の前面側に突設形成されている。該壁部101b10、101a10の突設高さは、隠し板105の側面部の厚みと同等に形成されており、隠し板105が当接したときに、該隠し板105の側面が外部に露出しないよう構成されている。 Wall portions 101b10 and 101a10 that contact when the hidden plate 105 is located at one of the end portions in the width direction of the container body are formed on the front side of the container body. The protruding heights of the wall portions 101b10 and 101a10 are formed to be equal to the thickness of the side surface portion of the hidden plate 105, and when the hidden plate 105 contacts, the side surface of the hidden plate 105 is not exposed to the outside. It is configured as follows.

次に、可動電源側端子部102Bの位置を移動する場合について図8を用いて説明を行う。例として、図8(a)は、固定端子部102Aには母線L2が接続され、可動電源側端子部102Bには母線Nと接続される場合(即ち供給される電圧は100V)を示し、図8(b)は、固定端子部102Aには母線L2が接続され、可動電源側端子部102Bには母線L1と接続される場合(即ち供給される電圧は200V)を示す。 Next, the case of moving the position of the movable power supply side terminal portion 102B will be described with reference to FIG. As an example, FIG. 8A shows a case where the bus L2 is connected to the fixed terminal 102A and the bus N is connected to the movable power supply side terminal 102B (that is, the supplied voltage is 100V). 8 (b) shows the case where the bus L2 is connected to the fixed terminal portion 102A and the bus L1 is connected to the movable power supply side terminal portion 102B (that is, the supplied voltage is 200V).

まず、図8(a)は、固定端子部102Aには母線L2が接続され、可動電源側端子部102Bには母線Nと接続される場合であるから、回路遮断器に供給される電圧値は100Vとなる。器体の幅方向において隠し板105は可動電源側端子102Bとは反対側の端部に位置し、可動電源側端子部102Bの位置する側の電圧表示部107には、100Vの文字が外部に露出して表示される。 First, FIG. 8A shows the case where the bus L2 is connected to the fixed terminal portion 102A and the bus N is connected to the movable power supply side terminal portion 102B, so the voltage value supplied to the circuit breaker is 100V. The hidden plate 105 is located at the end opposite to the movable power supply side terminal 102B in the width direction of the body, and the voltage display portion 107 on the side where the movable power supply side terminal portion 102B is located has 100V characters on the outside. It is exposed and displayed.

次に、分電盤から回路遮断器を取り外し、端子に母線が接続されていない状態において、可動電源側端子102Bを(a)の初期位置から(b)の他方の側面側にスライド移動させ始めると、可動電源側端子102Bの前面側に設けられたラック102B1とピニオン106の歯の噛み合いにより、ピニオンは図中において反時計回りに回転を始める。同時に、ピニオン106の歯と噛み合っている隠し板105の背面側に設けられたラック105bに力が伝達され、前記可動電源側端子102Bをスライド移動させる方向とは反対の方向に移動を始める。ラックとピニオンの歯は1対1で対応しているため、隠し板105の移動量と可動電源側端子部102Bの移動量は同じであり、可動電源側端子102Bを他方の側面側に移動させ終えた場合には、隠し板105も初期位置から他方の側面側に移動し終える。 Next, the circuit breaker is removed from the distribution board, and the movable power supply side terminal 102B is slid from the initial position of (a) to the other side surface of (b) in a state where the bus bar is not connected to the terminal. Then, the pinion starts to rotate counterclockwise in the drawing due to the meshing of the teeth of the rack 102B1 provided on the front side of the movable power supply side terminal 102B and the pinion 106. At the same time, a force is transmitted to the rack 105b provided on the back side of the hidden plate 105 meshing with the teeth of the pinion 106, and the movement starts in a direction opposite to the direction in which the movable power supply side terminal 102B is slid. Since the rack and pinion teeth have a one-to-one correspondence, the amount of movement of the hidden plate 105 and the amount of movement of the movable power supply side terminal portion 102B are the same, and the movable power supply side terminal 102B is moved to the other side surface side. When finished, the hidden plate 105 also finishes moving from the initial position to the other side surface.

図8(b)の状態では、固定端子部102Aには母線L2が接続され、可動電源側端子部102Bには母線L1と接続される場合であるから、回路遮断器に供給される電圧値は200Vとなる。可動電源側端子部102Bの位置する側の前面側においては、可動電源側端子部102Bが位置しない側の電圧表示部107は隠し板105のベースにより隠蔽され、可動電源側端子部102Bが位置する側の電圧表示部107が現れている。この場合の電圧表示部107は200Vの文字が表示される。 In the state of FIG. 8B, the bus L2 is connected to the fixed terminal portion 102A, and the bus L1 is connected to the movable power supply side terminal portion 102B. Therefore, the voltage value supplied to the circuit breaker is 200V. On the front side where the movable power supply side terminal portion 102B is located, the voltage display portion 107 on the side where the movable power supply side terminal portion 102B is not located is concealed by the base of the hidden plate 105, and the movable power supply side terminal portion 102B is located. The voltage display 107 on the side appears. In this case, the voltage display unit 107 displays 200V characters.

このように可動電源側端子部102Bと隠し板105とが互いに連動し、可動電源側端子102Bをスライド移動させる方向とは反対の方向に隠し板105が移動されるよう構成したから、作業者は可動電源側端子部の位置を的確に把握しやすく、可動電源側端子部102Bを母線と接続する一方の位置において、常にその前面側に、回路遮断器に供給される電圧値の表示の露出が行える。
他方の位置において回路遮断器に供給される電圧は前記隠し板105の背面側に位置して隠蔽されるよう構成したから、器体の前面側から端子部を臨んだ場合に、接続する母線の違いを、器体の前面に設けられた電圧表示の違い、即ち端子位置の違いとして目視確認することができ、端子装置と母線とを選択的に接続する場合や、端子装置と母線を接続した後であっても、どの回路遮断器がどの母線を選択して接続されているのかが直接的に把握しやすい。器体の端子部における前面側の、隠し板105に隠蔽されない側の略全面を電圧表示部として用いることができるため、電圧表示部を大きくとれ視認性がよく、作業をする者にとって接続母線や供給電圧の誤認を生じさせにくく、配線確認作業性が高い回路遮断器の端子構造を提供することができる。
Since the movable power supply side terminal portion 102B and the hidden plate 105 are interlocked with each other and the hidden plate 105 is moved in the direction opposite to the sliding direction of the movable power supply side terminal 102B, the operator can It is easy to accurately grasp the position of the movable power supply side terminal portion, and at one position where the movable power supply side terminal portion 102B is connected to the bus, the display of the voltage value supplied to the circuit breaker is always on the front side. Yes.
Since the voltage supplied to the circuit breaker at the other position is configured to be concealed by being located on the back side of the hidden plate 105, when the terminal portion is faced from the front side of the container body, The difference can be visually confirmed as the difference in voltage display provided on the front of the vessel, that is, the difference in terminal position. When the terminal device and the bus are selectively connected, the terminal device and the bus are connected. Even later, it is easy to directly grasp which circuit breaker is selected and which bus is connected. Since almost the entire surface of the terminal portion of the body that is not concealed by the concealment plate 105 can be used as the voltage display portion, the voltage display portion can be taken large and has good visibility, and the connection busbar or It is possible to provide a terminal structure for a circuit breaker that hardly causes misidentification of a supply voltage and has high wiring confirmation workability.

なお、可動電源側端子部の刃受と回路遮断器内部の主導体とはより線により接続されており、前記幅方向に連続的に移動するときの妨げにならないよう、移動量分の余裕を持たせた長さとしている。 Note that the blade holder of the movable power supply side terminal portion and the main conductor inside the circuit breaker are connected by a stranded wire, so that there is an allowance for the amount of movement so as not to hinder continuous movement in the width direction. The length is given.

また、前記電圧表示部における電圧の表示は、文字による表示の他、器体の幅方向における略中央部を境に色分けを行ったり、その他接続する母線の種類を記載することにより行ってもよい。色分けは、給電電圧を識別するために赤と白、赤と黒というように、各々で色相を違えたり、また、明度、彩度を違えて構成するとよい。また、母線の種類をL1、Nというように表示したり、色分けと文字による表示を組み合わせて行ってもよい。 Further, the voltage display in the voltage display unit may be performed by color-coding at the substantially central portion in the width direction of the body, or by describing the type of busbar to be connected in addition to the display by characters. . In order to identify the power supply voltage, the color classification may be configured such that red and white, red and black have different hues, and lightness and saturation are different. Also, the bus types may be displayed as L1, N, or a combination of color coding and character display.

また、可動電源側端子102Bの移動に伴い隠し板105の移動が行われる際に、所定の位置に可動電源側端子102B及び隠し板105が到達したことを操作時に伝達すること、また、所定の位置に可動電源側端子102B及び隠し板105が到達しやすくすることを目的として、器体の電源側端子部102Bの前面側と隠し板105の背面側に夫々移動時に乗り越える突起部108a1、108a2、108b、105c1、105c2を設けて構成している。可動電源側端子102Bを器体の幅方向に移動させる場合に連動して移動する隠し板105の背面側の突起が器体の前面側の突起と当接し乗り越えることにより、可動電源側端子102Bを一方の位置から他方の位置に移動させるときに、前記突起を乗り越えることにより適度なクリック感が得られ、作業者は、可動電源側端子部102Bを切替えたことを感覚的に認識することができ、同時に可動電源側端子102B及び隠し板105が所定の位置に到達しやすくなる。 In addition, when the hidden plate 105 is moved along with the movement of the movable power source side terminal 102B, it is transmitted during operation that the movable power source side terminal 102B and the hidden plate 105 have reached predetermined positions. For the purpose of making the movable power supply side terminal 102B and the concealed plate 105 easily reach the positions, the protrusions 108a1, 108a2, which are moved over to the front side of the power supply side terminal portion 102B of the container and the back side of the concealed plate 105, respectively, 108b, 105c1, and 105c2 are provided. When the movable power supply side terminal 102B is moved in the width direction of the container, the protrusion on the back side of the hidden plate 105 that moves in conjunction with the protrusion on the front surface side of the container touches and gets over the movable power supply side terminal 102B. When moving from one position to the other, an appropriate click feeling can be obtained by overcoming the protrusion, and the operator can sensibly recognize that the movable power supply side terminal portion 102B has been switched. At the same time, the movable power supply side terminal 102B and the hidden plate 105 can easily reach a predetermined position.

また、隠し板105の前面側及び背面側には、前記器体の幅方向に溝部105d、105eが設けられている。溝部を設けて、部分的に隠し板の厚みを薄くすることにより、前記突起同士が乗り越える際に、隠し板を弾性的に撓みやすくしている。 Further, on the front side and the back side of the hidden plate 105, grooves 105d and 105e are provided in the width direction of the container. By providing the groove and partially reducing the thickness of the hidden plate, the hidden plate is elastically easily bent when the protrusions get over.

尚、本発明は、上記実施形態に限定されるものではなく、本発明の要旨を逸脱しない範囲で種々の変更が可能である。 In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention.

前述した電圧表示部107は、文字、色彩による表示を行った例を示したが、回路遮断器が配設される分電盤の設置場所によっては薄暗い場所に設置されること可能性がある。このため、電圧表示部や第二の操作部の位置が作業者にとって明確には分かりにくくなる可能性があることに鑑み、回路遮断器1における前記可動電源側端子部102B側の器体内部の導体と前記固定端子部102A側の器体内部の導体とから電源を得る発光手段を器体に配置し、該発光手段の発光により前記電圧表示部や第二の操作部の位置が認識しやすくなるよう構成してもよい。 Although the voltage display unit 107 described above is an example in which characters and colors are displayed, there is a possibility that the voltage display unit 107 may be installed in a dim place depending on the installation location of the distribution board where the circuit breaker is installed. For this reason, in view of the possibility that the positions of the voltage display unit and the second operation unit may be clearly unclear to the operator, the circuit breaker 1 has the inside of the body on the movable power supply side terminal unit 102B side. A light emitting means for obtaining power from a conductor and a conductor inside the container on the fixed terminal portion 102A side is arranged in the container, and the position of the voltage display section and the second operation section can be easily recognized by light emission of the light emitting means. You may comprise.

例えば、図10に示したように、器体の前面側に配置された突部壁面Aに発光手段400を配置して、該発光手段400から器体の電源側端子側を照らすように構成するとよい。これにより、薄暗い場所においても、電源表示部107付近が発光手段400により照らされることにより視認性が向上する。 For example, as shown in FIG. 10, when the light emitting means 400 is arranged on the protrusion wall surface A arranged on the front side of the container, and the power supply side terminal side of the container is illuminated from the light emitting means 400. Good. Thereby, even in a dim place, the vicinity of the power display unit 107 is illuminated by the light emitting means 400, thereby improving visibility.

発光手段400は、前記可動電源側端子部102B側の器体内部の導体と前記固定端子部102A側の器体内部の導体とから電力を得るため、それぞれの導体に接続された整流回路、抵抗回路を介して設けられる。発光手段としては、LEDやELパネルなどを用いるとよい。 The light emitting means 400 obtains electric power from the conductor inside the container on the movable power supply side terminal portion 102B side and the conductor inside the container on the fixed terminal portion 102A side, so that the rectifier circuit and resistance connected to each conductor It is provided via a circuit. As the light emitting means, an LED, an EL panel, or the like may be used.

また、可動電源側端子部102Bの位置に応じて、回路遮断器に供給される電圧が変わることから、供給電圧の違いによって発光手段400が破壊しないよう、定電流回路を設けて構成し、常に発光手段が発光するように構成するとよい。 In addition, since the voltage supplied to the circuit breaker varies depending on the position of the movable power supply side terminal portion 102B, a constant current circuit is provided so that the light emitting means 400 is not destroyed due to a difference in supply voltage. The light emitting means may be configured to emit light.

また、発光手段を複数設けて、回路遮断器に供給される電圧に応じて、電流を供給するLEDを違えるように構成してもよい。LEDの発光色を変えておくことにより、例えば、電圧が100Vのときは白色、電圧が200Vのときは赤色のLEDが発光するように回路を設けてもよい。 Moreover, you may comprise so that LED which supplies an electric current according to the voltage provided with two or more light emission means according to the voltage supplied to a circuit breaker may be changed. By changing the light emission color of the LED, for example, a circuit may be provided so that a white LED emits light when the voltage is 100V and a red LED emits light when the voltage is 200V.

また、この他、電圧表示部107に透過性を持たせて構成し、発光手段を該電圧表示部107の背面側に設けて、該背面側から前面側を照らすことにより、電圧表示部の文字や色彩が前面側から明確に分かるように構成してもよい。 In addition, the voltage display unit 107 is configured to have transparency, and a light emitting means is provided on the back side of the voltage display unit 107 so that the front side is illuminated from the back side. It may be configured such that the color can be clearly seen from the front side.

例えば、電圧表示部107を光の透過性を持たせた樹脂製シートで構成するとよい。 For example, the voltage display unit 107 may be formed of a resin sheet having light permeability.

図11には、第1の形態の回路遮断器を複数並設した場合の図を示している。
いずれの場合においても、可動電源側端子部の位置により回路遮断器に接続する母線の種類や供給する電圧を回路遮断器の前面側から一目瞭然に識別することができる。
このように、個々の回路遮断器に対して、接続する母線の種類や供給する電圧の大きさが識別しやすいことに加え、複数の回路遮断器を並設配置した場合においても、どの回路遮断器がどの母線を選択して接続しているのか、どの回路遮断器にいくらの電圧が供給されているのかが直接的に把握しやすい。
In FIG. 11, the figure at the time of arranging the circuit breaker of the 1st form in parallel is shown.
In any case, the type of bus connected to the circuit breaker and the supplied voltage can be clearly identified from the front side of the circuit breaker by the position of the movable power supply side terminal portion.
In this way, for each circuit breaker, in addition to easy identification of the type of bus to be connected and the magnitude of the supplied voltage, any circuit breaker can be used even when multiple circuit breakers are arranged in parallel. It is easy to directly grasp which bus is selected and connected to the circuit and what voltage is supplied to which circuit breaker.

本発明は、分電盤に設けられる通常の回路遮断器に適用可能であり、2極回路遮断器のほか、例えば、3極回路遮断器などにも適用が可能である。前記共通端子部や可動電源側端子部が複数個設けられている場合には、それぞれの可動電源側端子部が器体の幅方向に移動する形態の他、器体の幅方向の移動に伴い、可動電源側端子部が器体の前面側から背面側の方向に変位するよう、斜め方向に移動できるように移動方向を形成してもよい。 The present invention can be applied to a normal circuit breaker provided in a distribution board, and can be applied to, for example, a three-pole circuit breaker in addition to a two-pole circuit breaker. In the case where a plurality of common terminal portions and movable power supply side terminal portions are provided, each movable power supply side terminal portion is moved in the width direction of the container in addition to the form in which each movable power supply side terminal portion is moved in the width direction of the container. The moving direction may be formed so that the movable power supply side terminal portion can move in an oblique direction so as to be displaced from the front side to the back side of the body.
