Description

この発明は、回路遮断器、特に１極分の開閉機構および過電流引き外し素子を具備した単極用遮断器を複数個積層した多極用遮断器の側面に、該多極用遮断器のトリップ動作に連動し、このトリップ動作したことを外部に知らしめる外付形付属器を配設した回路遮断装置に関し、詳しくはこの回路遮断装置に漏電トリップ機能、あるいは漏電検出機能を付加したものである。   The present invention provides a circuit breaker, in particular, a multipole circuit breaker on the side of a multipole circuit breaker in which a plurality of single-pole circuit breakers equipped with a switching mechanism for one pole and an overcurrent tripping element are stacked. In connection with the trip operation, the circuit breaker is equipped with an external attachment that informs the outside of the trip operation. Specifically, this circuit breaker is equipped with a leakage trip function or leakage detection function. is there.

配線用遮断器や漏電遮断器などの回路遮断器には、この回路遮断器に具備されたハンドルを操作することにより電路を開閉する機能、すなわちスイッチ機能だけではなく、過電流が流れることによる電線や負荷機器の焼損、さらには漏電電流が流れることによる感電や火災を未然に防止するために電路を遮断するという大きな役目を担っている。この電路の遮断は、回路遮断器のハンドルの位置、あるいは回路遮断器から突出した漏電表示ボタンで判別可能であるほか、当該回路遮断器に内蔵された警報接点を活用し、例えば集中監視室でブザーあるいはランプなどで知り得ることができるようになっている。   Circuit breakers such as circuit breakers for circuit breakers and earth leakage circuit breakers have a function to open and close an electric circuit by operating a handle provided in the circuit breaker, that is, not only a switch function but also an electric wire caused by an overcurrent flowing. It plays a major role of interrupting the electrical circuit to prevent electric shocks and fires caused by the burnout of the load equipment, and the leakage current. This circuit breaker can be identified by the position of the handle of the circuit breaker or the leakage indication button protruding from the circuit breaker, and by utilizing the alarm contact built into the circuit breaker, for example, in a centralized monitoring room You can get to know with a buzzer or a lamp.

ところで、この回路遮断器には、用途、あるいは通電能力に応じて大小さまざまな外形を有していることは周知の通りであるが、特に家庭用の分電盤に使用される小形の回路遮断器においては、限られた外形寸法の中に、前述したスイッチ機能に係る開閉機構部や、過電流を検出してこの開閉機構部を作動させる、例えば電磁石装置、さらには接点を開離することによって発生するアークを裁断する消弧装置など、回路遮断器として必要不可欠な装置を最優先で搭載せねばならず、前述した警報接点を内蔵できにくいのが実情である。そこで、回路遮断器とは別体の筐体Ａに警報接点を具備させ、これを当該回路遮断器の側面に配設し、当該回路遮断器の開閉機構部と連結させることが知られている（例えば、特許文献１参照）。なお、本明細書では、この「別体の筐体Ａ」を、これ以降「外付形付属器」と呼ぶこととする。   By the way, it is well known that this circuit breaker has various sizes of large and small depending on the application or current-carrying capacity, but it is particularly small circuit breaker used for domestic distribution boards. In the case, the opening / closing mechanism part related to the switch function described above or the opening / closing mechanism part is operated by detecting an overcurrent, for example, an electromagnet device, and further, the contact is opened in a limited external dimension. In reality, it is difficult to incorporate the above-mentioned alarm contact, because it is necessary to mount a device that is indispensable as a circuit breaker, such as an arc extinguishing device that cuts off the arc generated by the above. Therefore, it is known that an alarm contact is provided in a casing A that is separate from the circuit breaker, which is disposed on the side surface of the circuit breaker and connected to the opening / closing mechanism of the circuit breaker. (For example, refer to Patent Document 1). In the present specification, the “separate casing A” is hereinafter referred to as an “external attachment”.

一方、前述した漏電電流を遮断する漏電遮断器は、配線用遮断器と同一外形、すなわち配線用遮断器に漏電機能を内蔵しながら、なおかつ外形寸法が配線用遮断器と同じであることが、最近の技術革新により各社とも一般的であるが、ここでも、小形の回路遮断器においては、前述と同様の理由で、やはり内蔵できにくいのが実情である。そこで、零相変流器など主回路に係る部品は、回路遮断器の負荷側に配置させた漏電検出ユニットに、また、引き外し素子など主回路には直接係らない部品は、回路遮断器の側面に配置させた漏電引外しユニットに、それぞれ内蔵させ、漏電検出ユニットと漏電引外しユニットを導体で接続させるとともに、当該回路遮断器の開閉機構部と漏電引外しユニットとを連結させることが知られている（例えば、特許文献２参照）。   On the other hand, the leakage breaker that cuts off the leakage current described above has the same outer shape as the wiring breaker, that is, the leakage breaker is built in the wiring breaker, and the outer dimensions are the same as the wiring breaker. Although it is common for each company due to recent technological innovations, it is still the case that small circuit breakers are still difficult to incorporate for the same reason as described above. Therefore, components related to the main circuit such as a zero-phase current transformer are connected to the leakage detection unit arranged on the load side of the circuit breaker, and components not directly related to the main circuit such as a tripping element are connected to the circuit breaker. It is known that each earth leakage trip unit placed on the side is built in, the earth leakage detection unit and the earth leakage trip unit are connected by a conductor, and the circuit breaker switching mechanism is connected to the earth leakage trip unit. (For example, refer to Patent Document 2).

なお、この特許文献２で開示された漏電遮断器では、回路遮断器の負荷側に漏電検出ユニットを配設することから、特に分電盤の寸法に制約がある場合においては好ましくないため、漏電引外しユニットに漏電検出ユニットを構成する部材を内蔵、すなわち、回路遮断器の側面のみに、漏電検出に必要な部材を全て内蔵させた別体の筐体Ｂを配置させ、漏電遮断器として形成されているものも知られている。なお、本明細書では、この「別体の筐体Ｂ」を、これ以降「漏電検出ユニット」と呼ぶこととする。   In the earth leakage breaker disclosed in Patent Document 2, since the earth leakage detection unit is disposed on the load side of the circuit breaker, it is not preferable particularly when the size of the distribution board is limited. Built-in member that constitutes a leakage detection unit in the trip unit, that is, a separate case B that contains all the members necessary for leakage detection is arranged only on the side of the circuit breaker to form a leakage breaker What is being known is also known. In the present specification, this “separate case B” will be referred to as “leakage detection unit” hereinafter.

家庭用の小形回路遮断器は、その外形の小ささ故に、過電流遮断に係る機能以外、つまり、これまで説明したように、警報接点や漏電遮断に係る機能は、当該回路遮断器の側面に配設されることが一般的であった。このことは、例えば受配電盤や動力分電盤に使用される比較的外形の大きい回路遮断器に比べて、その回路遮断器が持ち得る機能の組み合わせに制約を受ける大きな要因となっていた。すなわち、一例を挙げると、家庭用の小形の漏電遮断器では警報接点を出力させることが極めて困難であり、使用者の要求に応えることができなかったのが実情であった。   Small circuit breakers for home use have small external dimensions, so that functions other than those related to overcurrent interruption, i.e., the functions related to alarm contacts and earth leakage interruption, are described on the side of the circuit breaker. It was common to arrange. This is a major factor that is restricted by the combination of functions that the circuit breaker can have, compared to a circuit breaker having a relatively large outer shape, which is used for, for example, a distribution board or a power distribution board. That is, for example, it is extremely difficult to output an alarm contact in a small-sized earth leakage breaker for home use, and the actual situation is that the user's request could not be met.

この発明は、上述のような課題を解決するためになされたもので、漏電検出機能を搭載した漏電検出ユニットを回路遮断器の側面に配設し、当該回路遮断器に漏電遮断機能を持たせながら、この回路遮断器が遮断したことを外部に知らしめる警報接点となる外付形付属器をも、当該回路遮断器の側面に配設可能とした回路遮断装置を得ることを目的とするものである。   The present invention has been made to solve the above-described problems, and a leakage detection unit equipped with a leakage detection function is disposed on the side of a circuit breaker so that the circuit breaker has a leakage blocking function. However, the purpose is to obtain a circuit breaker that can also be provided on the side of the circuit breaker with an external attachment that serves as an alarm contact that informs the outside that this circuit breaker has broken. It is.

実施の形態１．
図１はこの発明の実施の形態１における回路遮断装置の正面図、図２は図１を各ユニット毎に分解した外観斜視図である。また、図３は、図１において、漏電検出ユニットのみの、特にその内部の配線状態を破線にて示した正面図である。さらに、図４および図５は、回路遮断器および外付形付属器のそれぞれカバーを外し、図１紙面上、Ａ方向から見た内部構造図、また、図６は、漏電検出ユニットのカバー３３の一部を切り欠き、図１紙面上、Ｂ方向から見た内部構造図である。なお、図４〜図６における（ａ）および（ｂ）は、それぞれ（ａ）が（漏電）トリップ状態、（ｂ）がＯＮ状態である。 Embodiment 1 FIG.
1 is a front view of a circuit breaker according to Embodiment 1 of the present invention, and FIG. 2 is an external perspective view of FIG. 1 disassembled for each unit. FIG. 3 is a front view of only the leakage detection unit in FIG. 4 and FIG. 5 show the internal structure of the circuit breaker and the external attachment, respectively, with the cover removed from the direction A in FIG. 1, and FIG. 6 shows the cover 33 of the leakage detection unit. FIG. 2 is an internal structure diagram seen from the B direction on the paper surface of FIG. In FIGS. 4 to 6, (a) and (b) show that (a) is a (leakage) trip state and (b) is an ON state, respectively.

図１に示すように、回路遮断装置１０１は、単極用回路遮断器１を複数個積層（この場合は４個）したもの（以下、これを回路遮断器１と称す）の紙面上、右側面に警報接点となる外付形付属器２を、さらにこの外付形付属器２の紙面上、右側面に漏電検出機能を持たせた漏電検出ユニット３を配設することで構成されている。回路遮断器１のハンドル１１と外付形付属器２のハンドル２１は図示しないピンなどによって連結されており、ハンドル１１の手動によるＯＮ（紙面上、下側から上側）およびＯＦＦ（紙面上、上側から下側）操作にハンドル２１が連動している。一方、漏電検出ユニット３のハンドル３１は、このハンドル３１に具備された係合部３１ａによってハンドル２１の紙面上、上側と係合している。すなわち、ハンドル３１をＯＦＦ方向に操作したときは、ハンドル１１（および２１）も連動するが、ハンドル１１のＯＦＦ操作では、ハンドル３１は連動せず、ＯＮ位置に静止したままとなる。然るに、この図１の状態では、漏電遮断あるいはハンドル３１にてＯＦＦ方向に操作（模擬漏電遮断に相当）したことを示している。なお、このことから、回路遮断器１の外部端子１４ａ、１４ｂは１４ａが電源側、１４ｂが負荷側となるのは周知の通りである。また、３３ａは、漏電検出機能が正常に動作し得るかどうかを確認する、やはり周知の漏電テストボタンである。   As shown in FIG. 1, a circuit breaker 101 includes a plurality of single-pole circuit breakers 1 (in this case, four pieces) laminated (hereinafter referred to as circuit breaker 1) on the right side of the drawing. An external attachment 2 serving as an alarm contact is provided on the surface, and a leakage detection unit 3 having a leakage detection function is provided on the right side of the external attachment 2 on the paper surface. . The handle 11 of the circuit breaker 1 and the handle 21 of the external attachment 2 are connected by a pin or the like (not shown), and the handle 11 is manually turned on (on the paper, from the bottom to the top) and off (on the paper, the top). The handle 21 is interlocked with the operation from the lower side. On the other hand, the handle 31 of the leakage detection unit 3 is engaged with the upper side of the handle 21 on the paper surface by an engaging portion 31 a provided on the handle 31. That is, when the handle 31 is operated in the OFF direction, the handle 11 (and 21) is also interlocked. However, when the handle 11 is OFF, the handle 31 is not interlocked and remains stationary at the ON position. However, the state shown in FIG. 1 indicates that the leakage is interrupted or the handle 31 is operated in the OFF direction (corresponding to the simulated leakage interrupt). From this, it is well known that the external terminals 14a and 14b of the circuit breaker 1 have the power supply side 14a and the load side 14b. 33a is a well-known leakage test button for confirming whether or not the leakage detection function can operate normally.

続いて回路遮断装置１０１の組立手順を説明する。図２に示すように、回路遮断器１と外付形付属器２は、外付形付属器２の筐体を成すベース２２に設けた爪２２ｂにより固定され、前述したとおり図示しないピンなどでハンドル１１、２１同士が連結されるが、このとき、回路遮断器１の後述する開閉機構部の動きを外付形付属器２に伝達させるため、ベース２２に設けた連結孔２２ａにトリップカム４１を嵌入しておく。すると、連結孔２２ａに相対向する位置に、回路遮断器１のカバー１３の図示しない連結孔（ベース１２の連結孔１２ａ（ただし、この連結孔１２ａはこの実施の形態では使われないので塞がれている）と同じものがカバー１３側にも設けられている）が設けられていることから、トリップカム４１がこの連結孔を通じて回路遮断器１の開閉機構部と係合する。これにより、回路遮断器１がトリップしたとき、外付形付属器２より警報接点を出力させることができる。   Next, the assembly procedure of the circuit breaker 101 will be described. As shown in FIG. 2, the circuit breaker 1 and the external attachment 2 are fixed by a claw 22 b provided on the base 22 that forms the housing of the external attachment 2. The handles 11 and 21 are connected to each other. At this time, the trip cam 41 is inserted into the connection hole 22a provided in the base 22 in order to transmit the movement of an opening / closing mechanism section, which will be described later, of the circuit breaker 1 to the external attachment 2. Insert. Then, a connection hole (not shown) of the cover 13 of the circuit breaker 1 (the connection hole 12a of the base 12 (however, this connection hole 12a is not used in this embodiment, so that it is blocked) at a position opposite to the connection hole 22a. Is provided on the cover 13 side), the trip cam 41 is engaged with the opening / closing mechanism of the circuit breaker 1 through this connection hole. Thereby, when the circuit breaker 1 trips, an alarm contact can be output from the external attachment 2.

回路遮断器１と外付形付属器２を固定したものに、漏電検出ユニット３のベース３２に設けた爪３２ｂにより、この漏電検出ユニット３をさらに固定することになるが、この漏電検出ユニット３は外付形付属器２と違い、主回路も接続する必要がある。すなわち、漏電検出ユニット３のベース３２より延在する端子カバー部３２ｃによって、その露出が覆われる導体３６の先端３６ａを、回路遮断器１の外部端子１４ｂに端子ネジ１４ｂ１（図４参照）によって締め付ける。この導体３６は、図３に示すように、先端３６ａ以外は、その接触による相間短絡を防ぐために、例えば絶縁チューブで被覆されており、４本まとめてベース３２の側面より挿通し、略９０度、紙面上、上方向に折り曲げたのちＵターンさせ、この電路の漏電電流を検出する周知の零相変流器３７を貫通後、外部端子３４に接続させている。図２に示すように、ベース３２には、外付形付属器２と同様、連結孔３２ａが設けられており、この連結孔３２ａにトリップカム４２を嵌入することで、漏電検出ユニット３の後述する開閉機構部の動き、すなわち、漏電動作を外付形付属器２の開閉機構部に伝達する。この伝達は、連結孔３２ａと相対向する位置に、外付形付属器２のカバー２３の図示しない連結孔（ベース２２の連結孔２２ａと同じものがカバー２３側にも設けられている）が設けられることで行われるのは、前述した回路遮断器１と外付形付属器２間の伝達と同様である。   The earth leakage detection unit 3 is further fixed to the fixed circuit breaker 1 and the external attachment 2 by a claw 32b provided on the base 32 of the earth leakage detection unit 3. The earth leakage detection unit 3 Unlike the external attachment 2, the main circuit must be connected. That is, the tip 36a of the conductor 36 whose exposure is covered by the terminal cover portion 32c extending from the base 32 of the leakage detection unit 3 is fastened to the external terminal 14b of the circuit breaker 1 by the terminal screw 14b1 (see FIG. 4). . As shown in FIG. 3, the conductor 36 is covered with, for example, an insulating tube except for the tip 36a in order to prevent a short circuit between the contacts. Then, after bending upward on the paper surface, it is U-turned, and is connected to the external terminal 34 after passing through a known zero-phase current transformer 37 that detects the leakage current of this electric circuit. As shown in FIG. 2, the base 32 is provided with a connection hole 32 a as in the external attachment 2, and the leakage cam detection unit 3 will be described later by inserting a trip cam 42 into the connection hole 32 a. The movement of the opening / closing mechanism, that is, the electric leakage operation is transmitted to the opening / closing mechanism of the external attachment 2. In this transmission, there is a connection hole (not shown) of the cover 23 of the external attachment 2 (the same as the connection hole 22a of the base 22 is also provided on the cover 23 side) at a position opposite to the connection hole 32a. What is performed by being provided is similar to the transmission between the circuit breaker 1 and the external attachment 2 described above.

然るに、この回路遮断装置１０１を使用するにあたり、使用者は回路遮断器１の外部端子１４ａに例えば電源側バーを、漏電検出ユニット３の外部端子３４に例えばフレキシブルな負荷側電線をそれぞれ接続し、例えば電灯などの負荷に給電を開始することになる。この給電状態において、何らかの原因で過電流、あるいは短絡による事故電流が流れた場合、回路遮断器１にて電路を遮断するとともに、この遮断したことを外付形付属器２に伝達させ、この外付形付属器２の開閉機構部が作動することで、外部端子２４に接続された、例えばこの回路遮断装置１０１から遠隔地に設置された図示しないブザーやランプが応動することで、使用者はその電路の異常を掴むことができる。また、この電路で漏電が発生した場合は、漏電検出ユニット３の開閉機構部が動作し、この動きが外付形付属器２、さらには回路遮断器１に伝達され、過電流発生時と同様に、回路遮断器１にて電路を遮断するとともに、外付形付属器２から警報を出力させる。なお、この実施の形態１では、回路遮断装置１０１はＲＣＢＯｓ（ｒｅｓｉｄｕａｌ ｃｕｒｒｅｎｔ ｏｐｅｒａｔｅｄ ｃｉｒｃｕｉｔ−ｂｒｅａｋｅｒｓ ｗｉｔｈ ｉｎｔｅｇｒａｌ ｏｖｅｒｃｕｒｒｅｎｔ ｐｒｏｔｅｃｔｉｏｎの略、すなわち過電流素子を備えた漏電遮断器）、外付形付属器２についてはＡＬ（ａｌａｒｍ ｓｗｉｔｃｈの略）とそれぞれ呼称されている。また、請求項で述べている「第一、第二の連結部材」とは、それぞれトリップカム４１、４２のことである。 However, in using this circuit breaker 101, the user connects, for example, a power supply side bar to the external terminal 14a of the circuit breaker 1, and a flexible load side wire, for example, to the external terminal 34 of the leakage detection unit 3, For example, power supply to a load such as an electric light is started. If an overcurrent or an accidental current due to a short circuit flows for some reason in this power supply state, the circuit breaker 1 cuts off the electric circuit, and transmits this interruption to the external attachment 2 to By operating the opening / closing mechanism of the shaped appendage 2, for example, a buzzer or a lamp (not shown) connected to the external terminal 24, which is installed at a remote location from the circuit breaker 101, responds. You can grasp the abnormality of the electric circuit. In addition, when a leakage occurs in this electric circuit, the opening / closing mechanism of the leakage detection unit 3 operates, and this movement is transmitted to the external attachment 2 and further to the circuit breaker 1, which is the same as when an overcurrent occurs. In addition, the circuit breaker 1 cuts off the electric circuit and outputs an alarm from the external attachment 2. In accordance with this embodiment 1, the circuit breaking apparatus 101 is RCBOs (r esidual c urrent operated circuit- b reakers with integral o vercurrent protection substantially, i.e. earth leakage breaker with an overcurrent device), external auxiliary unit 2 are respectively referred to as AL (abbreviation of al arm switch). The “first and second connecting members” described in the claims refer to the trip cams 41 and 42, respectively.

前述した各ユニット間での「伝達」が本発明の要部であるため、図４〜６に基づきさらに詳しく説明する。図４（ａ）において、ハンドル１１を紙面上、時計方向に回動することで力線を越え、開閉機構部１５を構成するラッチ１５１およびアーム１５２がラッチピン１５３を回動中心として、紙面上、反時計方向への回動することに伴い、図４（ｂ）に示すように、可動接触子１６１が固定子１６２に接触し負荷へ給電可能となることは周知の通りである。この閉状態で過電流が発生すれば、詳述しないが、バイメタル１７あるいは電磁石装置１８が作動し、開閉機構部１５および可動接触子１６１が、図４（ａ）に示す位置となる。したがって、トリップカム４１の回路遮断器１側に嵌入された先端４１ａが、（ａ）と（ｂ）の位置の違いで明らかなように、ＯＮ⇔トリップ間で移動することになる。なお、図４（ｂ）、すなわち、ＯＮ状態から、ハンドル１１を紙面上、反時計方向に回動させたＯＦＦ状態も図４（ａ）と同じであるが、前述した先端４１ａの移動速度に差異が現れることになる。   Since “transmission” between the units described above is a main part of the present invention, it will be described in more detail with reference to FIGS. In FIG. 4 (a), the handle 11 is exceeded clockwise by rotating the handle 11 in the clockwise direction, and the latch 151 and the arm 152 constituting the opening / closing mechanism unit 15 have the latch pin 153 as the rotation center on the paper surface. As shown in FIG. 4B, it is well known that the movable contact 161 comes into contact with the stator 162 and can supply power to the load as it rotates counterclockwise. If an overcurrent occurs in this closed state, although not described in detail, the bimetal 17 or the electromagnet device 18 operates, and the opening / closing mechanism 15 and the movable contact 161 are in the positions shown in FIG. Therefore, the tip 41a fitted on the circuit breaker 1 side of the trip cam 41 moves between ON and ⇔ trips as is apparent from the difference in position between (a) and (b). 4B, that is, the OFF state in which the handle 11 is rotated counterclockwise on the paper surface from the ON state is the same as FIG. 4A, but the moving speed of the tip 41a described above is the same. Differences will appear.

この移動により、外付形付属器２側に嵌入された先端４１ｂも、図５（ａ）および（ｂ）に示すように、この外付形付属器２の開閉機構部２５を構成するラッチ２５１およびアーム２５２の間で同様に移動する。その結果、この外付形付属器２に内蔵されたスイッチ２６を構成する可動接触子２６１が回動、すなわち、それまで固定子２６２との導通から固定子２６３との導通へと切り換わることで、これら固定子２６２、２６３に接続された外部端子２４の負荷となる、例えばランプの点灯パターンが変更となる。なお、この実施の形態では、外部端子２４は、いわゆる１ｃ接点を構成しているため３個具備されているが、この３個に限定されるわけではなく、１ａ接点、もしくは１ｂ接点となる２個であっても構わない。また、スイッチ２７は、回路遮断器１の開閉状態に連動した、いわゆる補助接点（ＡＸ（ａｕｘｉｌｉａｒｙ ｓｗｉｔｃｈの略）と呼称される）であり、ＯＦＦ操作、あるいはトリップ動作の如何に拘わらず、可動接触子１６１の接離にあわせて切り換わる。前述したように、回路遮断器１のハンドル１１の位置だけでは、この回路遮断器１がＯＦＦ操作されたのか、電路で過電流が発生したかはわからないが、このように外付形付属器２に、ＡＬおよびＡＸを混載させることで、回路遮断器１の状態、ひいては電路の状況をより正確に掴むことができる。ただし、このＡＸについては、本発明とは直接、関係ないので、前述した先端４１ａの移動速度の差異ともども、その詳しい説明は省略する。 As a result of this movement, the tip 41b fitted on the external attachment 2 side also has a latch 251 that constitutes the opening / closing mechanism 25 of the external attachment 2 as shown in FIGS. 5 (a) and 5 (b). And move similarly between the arms 252. As a result, the movable contact 261 that constitutes the switch 26 built in the external attachment 2 rotates, that is, switches from conduction with the stator 262 to conduction with the stator 263 until then. The load pattern of the external terminal 24 connected to the stators 262 and 263, for example, the lamp lighting pattern is changed. In this embodiment, three external terminals 24 constitute so-called 1c contacts, but are provided with three external terminals 24. However, the number of external terminals 24 is not limited to three, and is 2a which is 1a contact or 1b contact. It may be individual. The switch 27 is interlocked with the opening and closing state of the circuit breaker 1, so-called an auxiliary contact (AX (a u x iliary switch Abbreviation) to be referred), irrespective of the OFF operation or tripping , Switching according to the contact and separation of the movable contact 161. As described above, it is not known from the position of the handle 11 of the circuit breaker 1 whether the circuit breaker 1 has been turned OFF or an overcurrent has occurred in the electric circuit. Moreover, by mounting AL and AX together, the state of the circuit breaker 1 and thus the state of the electric circuit can be grasped more accurately. However, since this AX is not directly related to the present invention, a detailed description thereof will be omitted even with the above-described difference in the moving speed of the tip 41a.

一方、図６（ｂ）において、漏電電流が発生した場合は、この漏電電流による導体３６を流れる電流の不平衡を零相変流器３７で検出し、この信号を電子回路部３８に送る。電子回路部３８では、この信号を増幅、およびその高さ・幅を基準レベルと比較し、漏電を検出すべくレベルと判断すれば、引き外しコイル３９を励磁させる。この励磁により、引き外しコイル３９のプランジャー３９ａが紙面上、右方向に吸引され、開閉機構部３５がこの図６（ｂ）の閉状態（漏電検出ユニット３自体は接点を具備していないが、回路遮断器１および外付形付属器２と合わせるため、便宜上、閉状態または開状態と呼ぶこととする）から（ａ）の開状態へ移行することになる。すると、この開閉機構部３５に嵌入されたトリップカム４２の先端４２ｂがこの移行に追従することになる。   On the other hand, in FIG. 6B, when a leakage current is generated, an unbalance of the current flowing through the conductor 36 due to the leakage current is detected by the zero-phase current transformer 37, and this signal is sent to the electronic circuit unit 38. The electronic circuit unit 38 amplifies this signal, compares its height and width with a reference level, and if it is determined to be a level for detecting electric leakage, the trip coil 39 is excited. By this excitation, the plunger 39a of the tripping coil 39 is attracted rightward on the paper surface, and the opening / closing mechanism 35 is in the closed state shown in FIG. 6B (although the leakage detection unit 3 itself has no contact). For the sake of convenience, the circuit breaker 1 and the external attachment 2 are referred to as a closed state or an open state) to shift to the open state of (a). Then, the tip 42b of the trip cam 42 fitted in the opening / closing mechanism 35 follows this transition.

このトリップカム４２は、外付形付属器２側に嵌入された先端４２ａを有しているため、前述したトリップカム４２の移動に伴い、外付形付属器２も先述した過電流によるトリップ動作と同様、閉状態（図５（ｂ））から開状態（図５（ａ））へ移行し、スイッチ２６（および２７）が切り換わる。とともに、この外付形付属器２の開閉機構部２５のトリップ動作がトリップカム４１を介して回路遮断器１側に伝達され、回路遮断器１がトリップ、すなわち、漏電遮断を行うことができる。   Since the trip cam 42 has a tip 42a fitted on the external attachment 2 side, the external attachment 2 is also tripped by the overcurrent described above with the movement of the trip cam 42 described above. In the same manner as the above, the closed state (FIG. 5B) is changed to the open state (FIG. 5A), and the switch 26 (and 27) is switched. At the same time, the trip operation of the opening / closing mechanism 25 of the external attachment 2 is transmitted to the circuit breaker 1 side via the trip cam 41, so that the circuit breaker 1 trips, that is, the earth leakage is interrupted.

このように、過電流発生による回路遮断器１のトリップ動作が、トリップカム４１を介して外付形付属器２を作動、また、漏電発生による漏電検出ユニット３のトリップ動作が、トリップカム４２を介して外付形付属器２を作動、さらにトリップカム４１を介して回路遮断器１を作動させることで、過電流時および漏電時とも、電路遮断と警報出力を同時に行うことができる。これは、各開閉機構部（１５、２５、３５）をトリップカム４１、４２で連結させたこともさることながら、このトリップカム４１、４２を複雑な形状にすることなく、また容易に嵌入できるよう、各開閉機構部の構成を近似させたことが大きい。さらに詳述すると、外付形付属器２の開閉機構部２５を中心に、回路遮断器１の開閉機構部１５と、漏電検出ユニット３の開閉機構部３５を、それぞれ、左右にほぼ等間隔に配置されるよう、各ユニット、特に漏電検出ユニット３の構成を工夫したことが前述した効果につながっている。このことにより、家庭用の小形の漏電遮断器であっても、その遮断による警報出力を得ることができ、遠方からの監視が必要となる、例えば重要回路の選定にあたり、制約を減らすことが可能となる。   Thus, the trip operation of the circuit breaker 1 due to the occurrence of overcurrent operates the external attachment 2 via the trip cam 41, and the trip operation of the leakage detection unit 3 due to the occurrence of leakage causes the trip cam 42 to By operating the external appendage 2 via the circuit and further operating the circuit breaker 1 via the trip cam 41, it is possible to simultaneously cut off the electric circuit and output an alarm in both cases of overcurrent and electric leakage. In addition to connecting the opening / closing mechanism portions (15, 25, 35) with the trip cams 41, 42, the trip cams 41, 42 can be easily fitted without making them complicated. Thus, the configuration of each opening / closing mechanism is approximated. More specifically, the opening / closing mechanism 15 of the circuit breaker 1 and the opening / closing mechanism 35 of the leakage detection unit 3 are arranged at substantially equal intervals on the left and right, respectively, with the opening / closing mechanism 25 of the external attachment 2 as the center. The arrangement of each unit, in particular, the leakage detection unit 3 so as to be arranged leads to the effect described above. This makes it possible to obtain an alarm output even when using a small earth leakage breaker for home use, and it is necessary to monitor from a distance. For example, it is possible to reduce restrictions when selecting important circuits. It becomes.

実施の形態２．
実施の形態１で述べた回路遮断装置は、例えば、漏電で遮断した場合、この回路遮断装置が具備された現場に出向けば、各ハンドル（１１、２１、３１）がＯＦＦ位置にある（図１参照）ことで、使用者は回路遮断装置が漏電で動作したことを知り得ることができる。一方、外付形付属器２に接続された、例えばブザーの作動だけでは、その電路の遮断が、過電流が起因なのか、漏電が起因なのか、見分けることはできないが、少なくとも、その電路の漏電遮断に対する警報出力に特化してもよい、という場合においては、前述した「伝達」方法を工夫することで可能となる。これを実施の形態２として説明する。なお、図７は、この実施の形態２をわかり易く説明するために、トリップカムと各開閉機構部のラッチ間の係合を模式化した図であり、（ａ）は比較のための前述の実施の形態１を、（ｂ）はこの実施の形態２を、それぞれ示し、（ｃ）および（ｄ）については、後述する実施の形態３を示す。 Embodiment 2. FIG.
For example, when the circuit breaker described in the first embodiment is cut off due to electric leakage, each handle (11, 21, 31) is in the OFF position when going to the site where the circuit breaker is provided (see FIG. 1), the user can know that the circuit breaker has been operated due to electric leakage. On the other hand, the operation of the buzzer connected to the external attachment 2 alone, for example, cannot distinguish whether the electric circuit is interrupted due to overcurrent or electric leakage, but at least the electric circuit In the case where it is possible to specialize in alarm output for electric leakage interruption, it is possible by devising the aforementioned “transmission” method. This will be described as a second embodiment. FIG. 7 is a diagram schematically showing the engagement between the trip cam and the latch of each opening / closing mechanism for the sake of easy understanding of the second embodiment, and FIG. (B) shows this Embodiment 2, and (c) and (d) show Embodiment 3 described later.

図７（ａ）に示すように、実施の形態１、すなわち、過電流でも漏電でも警報出力を得るには、外付形付属器２の開閉機構部２５を構成する部材の一つである、ラッチ２５１に第一の受け部２５１ａ、第二の受け部２５１ｂ、および伝達部２５１ｃが必要となる。一方、この実施の形態２では、図７（ｂ）に示すように、第一の受け部２５１ａを除去させている。このことにより、漏電時においては、漏電検出ユニット３のラッチ３５１に連動したトリップカム４２の動きが第二の受け部２５１ｂに伝達されてラッチ２５１が動き、このラッチ２５１の動きにより伝達部２５１ｃを介してトリップカム４１が連動することで、回路遮断器１のラッチ１５１が作動し電路を遮断する。逆に、過電流時においては、ラッチ１５１が作動することで電路を遮断するものの、このラッチ１５１の動きにトリップカム４１が連動するだけで、外付形付属器２のラッチ２５１は静止したままである。   As shown in FIG. 7 (a), in order to obtain an alarm output in the first embodiment, that is, overcurrent or electric leakage, it is one of the members constituting the open / close mechanism 25 of the external attachment 2. The latch 251 requires the first receiving part 251a, the second receiving part 251b, and the transmission part 251c. On the other hand, in the second embodiment, as shown in FIG. 7B, the first receiving portion 251a is removed. Thus, at the time of electric leakage, the movement of the trip cam 42 interlocked with the latch 351 of the electric leakage detection unit 3 is transmitted to the second receiving portion 251b and the latch 251 moves, and the movement of the latch 251 causes the transmission portion 251c to move. When the trip cam 41 is interlocked with each other, the latch 151 of the circuit breaker 1 is operated to interrupt the electric circuit. On the contrary, in the case of an overcurrent, the electric circuit is cut off by operating the latch 151, but the trip cam 41 is interlocked with the movement of the latch 151, and the latch 251 of the external attachment 2 remains stationary. It is.

すなわち、漏電による電路遮断では、ラッチ２５１が作動することで警報出力が行われるが、過電流による電路遮断では、ラッチ２５１は作動しないので警報出力は行われない。このことにより、使用者は外付形付属器２に接続された例えばブザーの応動が、漏電遮断であると素早く確定させることができるので、点検、あるいは復旧作業が効率よく行われる。この漏電遮断に連動させた外付形付属器２は、実施の形態１で説明したＡＬに対してＥＡＬ（ｅａｒｔｈ ａｌａｒｍ ｓｗｉｔｃｈの略）と呼称されており、これらＡＬ、あるいはＥＡＬを、その電路の事情などを鑑み、使用者側にて適宜選択すればよい。なお、ＥＡＬを装着させた場合には、回路遮断器１のハンドル１１と外付形付属器２のハンドル２１を連結させるピンは不要である。 That is, in the electric circuit interruption due to electric leakage, an alarm is output when the latch 251 is activated, but in the electric circuit interruption due to an overcurrent, the latch 251 is not activated and no alarm output is performed. As a result, the user can quickly determine that the response of, for example, the buzzer connected to the external appendage 2 is an electric leakage interruption, so that the inspection or the recovery work can be performed efficiently. The ground fault interrupter external auxiliary unit 2 which is interlocked in is called EAL (an abbreviation of e arth al arm switch) against AL described in the first embodiment, these AL, or EAL, the In view of the circumstances of the electric circuit, etc., the user may select as appropriate. In addition, when EAL is mounted, a pin for connecting the handle 11 of the circuit breaker 1 and the handle 21 of the external attachment 2 is unnecessary.

実施の形態３．
続いて、図７（ｃ）および（ｄ）を実施の形態３として説明する。この実施の形態３の特長は漏電発生時、電路の遮断はさせないことである。まず、図７（ｃ）では、伝達部２５１ｃを除去させている。このことにより、漏電時においては、漏電検出ユニット３のラッチ３５１に連動したトリップカム４２の動きが第二の受け部２５１ｂに伝達されてラッチ２５１は動くが、このラッチ２５１の動きは伝達部２５１ｃがないことによりトリップカム４１には伝達されない。すなわち、漏電が発生しても、外付形付属器２から警報出力が行われるだけで電路遮断は行わない。なお、ラッチ２５１の第一の受け部２５１ａが具備されていることから、過電流遮断によっても警報出力は行われる。 Embodiment 3 FIG.
Subsequently, FIGS. 7C and 7D will be described as a third embodiment. The feature of the third embodiment is that the electric circuit is not interrupted when a leakage occurs. First, in FIG.7 (c), the transmission part 251c is removed. As a result, at the time of electric leakage, the movement of the trip cam 42 interlocked with the latch 351 of the electric leakage detection unit 3 is transmitted to the second receiving portion 251b and the latch 251 moves, but the movement of the latch 251 is transmitted to the transmitting portion 251c. No transmission is made to the trip cam 41 due to the absence. That is, even if a leakage occurs, only an alarm is output from the external attachment 2 and the circuit is not interrupted. In addition, since the first receiving portion 251a of the latch 251 is provided, the alarm output is performed even when the overcurrent is interrupted.

すなわち、この図７（ｃ）は、実施の形態１と同様、警報出力が過電流（遮断）が起因なのか、漏電（非遮断）が起因なのかは特定することができない、いわゆるＡＬを搭載した回路遮断装置となる。一方、図７（ｄ）では、ラッチ２５１にはこれまで説明した各部材、つまり、第一の受け部２５１ａ、第二の受け部２５１ｂ、および伝達部２５１ｃは備えているものの、トリップカム４１が具備されていない。このことにより、回路遮断器１の遮断動作が外付形付属器２には伝達されないので、警報出力は漏電（非遮断）のみに起因していると即断できる、いわゆるＥＡＬを搭載した回路遮断装置となる。いずれにしろ、上述した通り、漏電では警報出力のみで、電路の遮断は行わないことより、この実施の形態３、つまり、図７（ｃ）および（ｄ）の回路遮断装置１０１はＭＣＢｓ（ｍｉｎｉａｔｕｒｅ ｃｉｒｃｕｉｔ ｂｒｅａｋｅｒｓの略）と呼称されている。このＭＣＢｓは、例えば、漏電が発生しても、負荷、特に機械装置などが安全な位置にあることを確認したのち、回路遮断器１のハンドル１１をＯＦＦ操作し、その電路の点検などを行いたいとき、つまり、早急な漏電遮断では不都合がある場合などに効果的である。 That is, FIG. 7C is equipped with a so-called AL that cannot specify whether the alarm output is caused by an overcurrent (cutoff) or a leakage (non-cutoff), as in the first embodiment. Circuit breaker. On the other hand, in FIG. 7D, the latch 251 is provided with each member described so far, that is, the first receiving portion 251a, the second receiving portion 251b, and the transmitting portion 251c, but the trip cam 41 is provided. It is not equipped. As a result, since the breaking operation of the circuit breaker 1 is not transmitted to the external attachment 2, a circuit breaker equipped with a so-called EAL that can immediately determine that the alarm output is caused only by a leakage (non-breaking). It becomes. In any case, as described above, in the case of electric leakage, only the alarm output is performed and the electric circuit is not interrupted, so that the circuit interrupter 101 in FIG. 7 (c) and FIG. 7 (d) has MCBs ( m It has been referred to as the abbreviation) of iniature circuit b reakers. For example, after confirming that a load, especially a mechanical device, etc. is in a safe position even if a leakage occurs, the MCBs turns off the handle 11 of the circuit breaker 1 and checks its electric circuit. This is effective when there is an inconvenience, such as when there is an inconvenience in the case of an immediate ground fault interruption.

以上、これまで説明した実施の形態１〜３より、外付形付属器２のラッチ２５１の各部材の機能は以下の通りとなる。
第一の受け部２５１ａ：回路遮断器１の過電流遮断を受ける
第二の受け部２５１ｂ：漏電検出ユニット２の漏電動作を受ける
伝達部２５１ｃ ：漏電動作によるラッチ２５１の動きを回路遮断器１に伝える
また、上記の各部材、あるいはトリップカム４１の有無により以下の製品群を構築することが可能となる。
ＡＬ付きＲＣＢＯｓ ：図７（ａ）に該当（実施の形態１）
ＥＡＬ付きＲＣＢＯｓ：図７（ｂ）に該当（実施の形態２）
ＡＬ付きＭＣＢｓ ：図７（ｃ）に該当（実施の形態３）
ＥＡＬ付きＭＣＢｓ ：図７（ｄ）に該当（ 同上 ）
すなわち、実施の形態１で説明した各開閉機構部（１５、２５、３５）を等間隔に配置したことによる漏電検出と警報出力の両立に加え、外付形付属器２の開閉機構部２５の構成部品などを工夫し、使用者のニーズに応じた外付形付属器２をそれぞれ用意することで、家庭用の小形回路遮断器であっても、受配電盤や動力分電盤に使用される比較的外形の大きい回路遮断器相当の機能を提供することが可能となる。 As mentioned above, from Embodiment 1-3 demonstrated so far, the function of each member of the latch 251 of the external attachment 2 is as follows.
First receiving portion 251a: receiving overcurrent interruption of circuit breaker 1 Second receiving portion 251b: receiving leakage operation of leakage detection unit 2 Transmission portion 251c: movement of latch 251 due to leakage operation to circuit breaker 1 In addition, the following product groups can be constructed depending on the presence or absence of the above-described members or the trip cam 41.
RCBOs with AL: Corresponds to FIG. 7A (Embodiment 1)
RCBOs with EAL: Corresponds to FIG. 7B (Embodiment 2)
MCBs with AL: Corresponds to FIG. 7C (Embodiment 3)
MCBs with EAL: Corresponds to Figure 7 (d) (Same as above)
In other words, in addition to the compatibility of leakage detection and alarm output by arranging the opening / closing mechanism sections (15, 25, 35) described in the first embodiment at equal intervals, the opening / closing mechanism section 25 of the external attachment 2 is provided. Even if it is a small circuit breaker for home use, it can be used for power distribution boards and power distribution boards by devising components and preparing external attachments 2 according to the needs of users. A function equivalent to a circuit breaker having a relatively large outer shape can be provided.

実施の形態４．
回路遮断装置１０１の組立手順は既に述べたが、この漏電検出と警報出力を両立させた回路遮断装置１０１を得るにあたっては、従来の回路遮断装置、すなわち、図１３で示すＡＬ付きＭＣＢｓ、および図１４で示すＲＣＢＯｓの、それぞれＭＣＢｓを共用して単にドッキングさせる、つまり、図８に示すように、回路遮断器１と漏電検出ユニット３のどちらか一方をスライドさせ、空いた空間に外付形付属器２を装着させることが、特に使用者側の既存の各ユニットを有効活用する意味でも好ましい。このドッキングにあたっては、特に、回路遮断器１の外部端子１４ｂと漏電検出ユニット３の導体３６との接続を考慮する必要があり、この点を実施の形態４として説明する。なお、図９はこの発明の実施の形態４における回路遮断器１の下面図、図１０は外部端子（１４ｂ）の外観斜視図である。また、図１１および図１２はこの発明の実施の形態４の変形例を示す漏電検出ユニットの下面図および外観斜視図である。 Embodiment 4 FIG.
Although the assembly procedure of the circuit breaker 101 has already been described, in order to obtain the circuit breaker 101 that achieves both leakage detection and alarm output, the conventional circuit breaker, that is, the MCBs with AL shown in FIG. The RCBOs shown in Fig. 14 are simply docked while sharing the MCBs, that is, as shown in Fig. 8, either the circuit breaker 1 or the leakage detection unit 3 is slid and attached to the open space. It is preferable that the device 2 is mounted particularly in the sense of effectively utilizing each existing unit on the user side. In this docking, it is particularly necessary to consider the connection between the external terminal 14b of the circuit breaker 1 and the conductor 36 of the leakage detection unit 3, which will be described as a fourth embodiment. 9 is a bottom view of the circuit breaker 1 according to Embodiment 4 of the present invention, and FIG. 10 is an external perspective view of the external terminal (14b). 11 and 12 are a bottom view and an external perspective view of a leakage detecting unit showing a modification of the fourth embodiment of the present invention.

図１０に示すように、外部端子１４ｂを構成するソルダレス端子１４ｂ２の紙面上、下部に位置する電線受け部１４ｂ２ａは平坦形状であるため、図９に示すように、漏電検出ユニット３の導体３６を紙面上、左右方向に移動させて端子ネジ１４ｂ１で締め付けることが可能である。すなわち、図９紙面上、導体３６を、ＲＣＢＯｓのときは実線の位置に、一方、本発明である回路遮断装置１０１、つまり、外付形付属器２を挿入したときは一点鎖線の位置に、それぞれ配されるよう、漏電検出ユニット３を適宜スライドさせればよい。このことにより、例えばＲＣＢＯｓからＥＡＬ付きＲＣＢＯｓへの急な仕様変更にも対応することができる。   As shown in FIG. 10, since the wire receiving portion 14b2a located on the lower side of the solderless terminal 14b2 constituting the external terminal 14b has a flat shape, the conductor 36 of the leakage detection unit 3 is arranged as shown in FIG. It is possible to move in the left-right direction on the paper and tighten with the terminal screw 14b1. That is, on the paper surface of FIG. 9, the conductor 36 is at the position of a solid line when RCBOs, while the circuit breaker 101 according to the present invention, that is, when the external attachment 2 is inserted, What is necessary is just to slide the leakage detection unit 3 suitably so that it may each be arranged. Accordingly, it is possible to cope with a sudden specification change from RCBOs to RCBOs with EAL, for example.

回路遮断装置１０１の定格電流がアップすると、言うまでもなく、導体３６の線径もアップする。然るに、ある定格電流以上では、導体３６の線径とソルダレス端子１４ｂ２の開口寸法の関係上、漏電検出ユニット３のスライドが困難なことも予想される。このような場合は、図１１に示すように、導体３６の一部に可撓部３６ｂを設けておけば、やはり漏電検出ユニット３のスライドが可能となるので、さらに使い勝手のよい、つまり定格電流の大小に左右されない回路遮断装置１０１を提供することができる。なお、この場合の、漏電検出ユニット３のベース３２より延在する端子カバー部３２ｃは、図１２に示すように、外付形付属器２の有無による、使い分け（（ａ）、３２ｃ⇔３２ｃ´）、または伸縮自在なスライド式（（ｂ）、３２ｃ´´）にしておけばよい。   Needless to say, when the rated current of the circuit breaker 101 increases, the wire diameter of the conductor 36 also increases. However, it is expected that the leakage detection unit 3 is difficult to slide above a certain rated current due to the relationship between the wire diameter of the conductor 36 and the opening size of the solderless terminal 14b2. In such a case, as shown in FIG. 11, if the flexible portion 36b is provided in a part of the conductor 36, the leakage detection unit 3 can be slid again. It is possible to provide the circuit breaker 101 that is not affected by the size of the circuit breaker 101. In this case, the terminal cover portion 32c extending from the base 32 of the leakage detection unit 3 is selectively used depending on the presence or absence of the external attachment 2 as shown in FIG. ), Or a slide type that can be expanded and contracted ((b), 32c ″).
