例えば特許文献1及び特許文献2のように,外部の導体側に,回路遮断器の端子に接続する導体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 an external conductor to the terminal device of a circuit breaker,
In circuit breakers that are wiring devices,
For example, as in Patent Document 1 and Patent Document 2, there is a device in which a switching device that selectively switches a conductor connected to a terminal of a circuit breaker is provided on the external conductor side.

特許文献1においては,図22に示したように,外部の導体の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外部の導体の足部(特許文献1の符号101,301601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601)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るものである。 In Patent Document 1, as shown in FIG. 22, a bus bar (reference numerals 1, 2, and 3 in Patent Document 1) that forms a main electric circuit of an external conductor and an external conductor connected to a terminal of a circuit breaker The switching device is provided between the legs (reference numerals 101, 301601, etc. of Patent Document 1). This switching device is provided in a hole of a long hole (reference number 601 of patent document 1) and a switching piece (reference number 8 of patent document 1) provided in a connection bar (reference number 6 of patent document 1) constituting the switching device. A conductor to be connected is selected by moving the position of a switching screw (reference numeral 7 in Patent Document 1) penetrated together to one end or the other end of the elongated hole and switching the conductor connected to the terminal of the circuit breaker. .

特許文献2においては,図23に示したように,特許文献1と同じく,外部の導体の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外部の導体の接続部(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導体を切替えるものである。 In Patent Document 2, as shown in FIG. 23, as in Patent Document 1, a bus bar (reference numerals 11, 12, and 13 in Patent Document 2) that forms the main electric path of the external conductor and a circuit breaker terminal are used. A switching device is provided between connecting portions of external conductors to be connected (reference numerals 1301, 2001, etc. in Patent Document 2). And a screw (reference numeral 17 of patent document 2) which penetrates both a long hole provided in a feed plate (reference numeral 20 of patent document 2) and a cylindrical conductor (reference numeral 18 of patent document 2) constituting the switching device. The conductor connected to the terminal of the circuit breaker is switched by selecting the conductor to be conducted by moving the position to one end or the other end of the elongated hole.

特許文献3においては,図24に示したように,回路遮断器側に,外部の導体を選択的に切替える切替部を設けたものである。特許文献3によれば,可動端子部材を,遮断器本体に対して電気的に脱着自在としたり,遮断器本体に対して回転自在に取り付けることにより,遮断器本体に対する可動端子部材の装着位置を変え,各主幹バーとの接続を切替可能とするものである。また,主幹バー接続用の端子金具を,遮断器本体に対して電気的に脱着自在としたり,遮断器本体に対して回転自在に取り付けることにより,遮断器本体に対する端子金具の装着位置を変え,各主幹バーとの接続を切替可能とするものである。 In Patent Document 3, as shown in FIG. 24, a switching unit for selectively switching external conductors is provided on the circuit breaker side. According to Patent Document 3, the mounting position of the movable terminal member with respect to the circuit breaker body can be determined by making the movable terminal member electrically detachable with respect to the circuit breaker body or being rotatably attached to the circuit breaker body. In other words, the connection with each main bar can be switched. In addition, the terminal bracket for connecting the main bar can be electrically attached to and detached from the circuit breaker body, or attached to the circuit breaker body so that it can be rotated.

上述した,外部の導体側に,回路遮断器の端子に接続する導体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25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。 The above-described apparatus provided with the switching device that selectively switches the conductor connected to the terminal of the circuit breaker on the external conductor side has the following problems. The switching unit in the switching device will be described with reference to FIG. 25 which schematically shows the switching head. 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 regard to (b) showing the case where the connection is switched for a part of the conductor, the arrangement of the screw heads located on the right side in the figure is different from the arrangement of 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, in the case of (c), which shows the case where connections are switched for many conductors, the arrangement of the screw heads varies and is totally 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。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, if only one 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. If an incorrect conductor is selected and connected to the circuit breaker, unnecessary voltage will be supplied to the load-side circuit, which may damage the load-side wiring and electrical equipment. There is. In addition, since a large number of screws need to be switched, improvement in workability is desired.

また,回路遮断器側に,外部の導体を選択的に切替える切替部を設けたものにあっては,次に示したような課題がある。特許文献3においては,回路遮断器に対してどの導体が接続されているのかを,電圧の表示を行うことで把握可能に構成している。
即ち,可動端子部材を,遮断器本体に対して電気的に脱着自在とした例においては,可動端子部材の装着場所が上段であるときには,遮断器本体の上面に設けた表示孔から可動端子部材の上面の色が見え,可動端子部材の装着場所が中段であるときには,可動端子部材の装着部下部隔壁の上面の色が見えることから,それぞれで区別を行い電圧の表示としているものである。
In addition, if the circuit breaker is provided with a switching unit that selectively switches external conductors, there are the following problems. In patent document 3, it is comprised so that it can grasp | ascertain which conductor is connected with respect to a circuit breaker by displaying a voltage.
That is, in the example in which the movable terminal member is electrically detachable from the circuit breaker body, when the movable terminal member is mounted at the upper stage, the movable terminal member is removed from the display hole provided on the upper surface of the circuit breaker body. When the mounting position of the movable terminal member is in the middle, the color of the upper surface of the lower partition wall of the mounting portion of the movable terminal member can be seen.

また,可動端子部材を,遮断器本体に対して回転自在に取り付けた例においては,可動端子部材の端面に電圧表示部を設けておき,可動端子部材の位置により選択された電圧を表示しているものである。 In an example in which the movable terminal member is rotatably attached to the breaker body, a voltage display is provided on the end surface of the movable terminal member to display the voltage selected according to the position of the movable terminal member. It is what.

このように,表示孔から色を識別することにより電圧の表示として接続されている導体を把握したり,また,電圧表示を確認して接続されている導体を把握する場合にあっては,周囲の明るさや暗かったり,部材の色調が似通っている場合にはその色や表示を確認しづらくなることが予想される。 In this way, by identifying the color from the display hole, it is possible to grasp the connected conductor as a voltage display, or when confirming the voltage display and grasp the connected conductor, It is expected that it is difficult to confirm the color and display when the brightness or darkness of the material is similar or the color tone of the members is similar.

特に,可動端子部材の装着位置,及び可動端子金具の装着位置は,切替の前後において遮断器本体の前面側(操作ハンドルが設けられている面)から臨んだ場合に互いに重なるように位置するため,回路遮断器を外部の導体に接続した後にあっては,どちらの導体に接続しているのかは,表示孔から見える色もしくは電圧表示によって把握することとなり,導体と端子との接続具合を直接的に確認把握することができず,接続を変更した導体の数が増えてくるとどちらの導体に接続しているのか,作業をする者にとって容易には把握することがしづらくなり,誤解が生じやすくなるおそれがあった。 In particular, the mounting position of the movable terminal member and the mounting position of the movable terminal fitting are positioned so as to overlap each other when facing from the front side of the circuit breaker body (surface on which the operation handle is provided) before and after switching. After connecting the circuit breaker to an external conductor, the conductor to which it is connected is determined by the color or voltage displayed from the display hole, and the connection between the conductor and the terminal is directly determined. If the number of conductors whose connections have been changed increases, it will be difficult for the operator to easily determine which conductor is connected, and misunderstandings will occur. There was a risk that it would likely occur.

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と外部の導体とを選択的に接続する場合や,端子装置と外部の導体を接続した後であっても,回路遮断器がどの導体を選択して接続しているのかが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,回路遮断器が複数存在する状態であっても,それぞれの回路遮断器に対して接続している導体を直接的に把握しやすく,切替や接続確認における作業性を向上させるとともに,作業をする者にとって誤認を生じさせにくい端子装置を有した回路遮断器を提供することを目的とする。

前記端子部102は,その内部には端子1021を内包しており,外郭1022は端子1021とは電気的に接続されていない非充電部として構成されている。前述した端子部102と接続線104との電気的な接続は,この端子と電気的な接続を行っている。端子部の外郭は,絶縁体で構成してもよいし,また,端子を絶縁物を介して保持することにより,端子とは絶縁を行ったうえで導体で構成してもよい。 The terminal portion 102 includes a terminal 1021 therein, and the outer shell 1022 is configured as a non-charging portion that is not electrically connected to the terminal 1021. The above-described electrical connection between the terminal portion 102 and the connection line 104 is an electrical connection with this terminal. The outline of the terminal portion may be made of an insulator, or may be made of a conductor after being insulated from the terminal by holding the terminal through an insulator.

ここで,端子1021の種類は,IEC947−1の規格やJIS C8201−1の規格に規定されているように,ねじ端子やピラー端子などのねじ式端子や,ねじなし端子の何れで構成してもよい。 Here, the type of the terminal 1021 is configured by any of a screw-type terminal such as a screw terminal and a pillar terminal and a screwless terminal as defined in the IEC947-1 standard and the JIS C8201-1 standard. Also good.

端子部102と器体101との取付けについては,器体101の一部に端子部の移動方向にスリット1011を設けて,該スリット1011を貫通するよう端子部102の外郭1022の器体側に設けた軸1022aを介して取付されている。また,図4に示したように,前記軸1022aの一端には,スリット1011から軸1022aが抜けてしまわないよう軸1022aの外形よりも大きく形成された抜止め部1022bが設けられている。 Regarding the attachment of the terminal portion 102 and the container body 101, a slit 1011 is provided in a part of the container body 101 in the moving direction of the terminal portion, and is provided on the container side of the outer shell 1022 of the terminal portion 102 so as to penetrate the slit 1011. It is attached via a shaft 1022a. Further, as shown in FIG. 4, a retaining portion 1022b formed larger than the outer shape of the shaft 1022a is provided at one end of the shaft 1022a so that the shaft 1022a does not come out of the slit 1011.

なお,器体101への端子部102の取付けにあたっては,器体101の部品の分割構成により適宜変えるとよい。例えば,器体101が前述の幅方向に分割されるような部品構成である場合には,器体101を組み合わせるときに,端子部102の軸1022aを予めスリット1011に沿わせた上で,器体を閉じるとよい。また,器体101が前述の幅方向ではなく,長手方向に分割されるような部品構成である場合には,抜止め部1022bを器体の方向に略クサビ状となるよう形成しておき,スリットに向けてクサビ状の部分を押込むように端子部102を嵌め込んで取付けるとよい。 In addition, when attaching the terminal part 102 to the container body 101, it is good to change suitably according to the division | segmentation structure of the component of the container body 101. FIG. For example, in a case where the container body 101 has a component configuration that is divided in the width direction described above, the shaft 1022a of the terminal portion 102 is placed along the slit 1011 in advance when the container body 101 is combined.

In addition, in the case where the container body 101 has a component configuration that is divided in the longitudinal direction instead of the width direction described above, the retaining portion 1022b is formed in a substantially wedge shape in the direction of the container body, The terminal portion 102 may be fitted and attached so as to push the wedge-shaped portion toward the slit.

また,端子部102における端子1021と,器体内部の導体との電気的な接続は,端子部の移動を妨げないように,例えばより線などの電線を用いて移動自在に接続してもよいし,その他,器体の内部もしくは外部において,スリット1011に沿って導体で形成した摺動部を設けて,この摺動部に圧接する弾性的な圧接部を端子1021に形成し,摺動部と端子とを圧接させて電気的な接続を行ったり,端子1021の一部に摺動部をクランプするクランプ部を形成して摺動部にクランプさせて端子と摺動部とを電気的に接続してもよい。なお,摺動部と器体内部の導体との電気的な接続は,より線などの電線や端子板などの平板を適宜加工して行ってもよい。 In addition, the electrical connection between the terminal 1021 in the terminal portion 102 and the conductor inside the container may be movably connected using an electric wire such as a stranded wire so as not to hinder the movement of the terminal portion. In addition, a sliding portion formed of a conductor is provided along the slit 1011 inside or outside the container body, and an elastic pressure contact portion that presses against the sliding portion is formed on the terminal 1021. Are electrically connected by pressing the terminal and the terminal, or a clamp part for clamping the sliding part is formed on a part of the terminal 1021 to be clamped on the sliding part to electrically connect the terminal and the sliding part. You may connect. The electrical connection between the sliding portion and the conductor inside the container may be performed by appropriately processing a wire such as a stranded wire or a flat plate such as a terminal plate.

このように回路遮断器1を構成することにより,器体1の前面側から端子部102に臨んだ場合に,接続位置の違いを,器体101に対する端子102の位置の違いとして直接的に目視確認することができ,端子1021と外部の導体とを選択的に接続する場合や,端子1021と外部の導体を接続した後であっても,どの導体を選択して接続しているのかが直接的に把握しやすい。 By configuring the circuit breaker 1 in this way, when facing the terminal portion 102 from the front side of the device body 1, the difference in the connection position is directly determined as the difference in the position of the terminal portion 102 with respect to the device body 101. It can be visually confirmed, and even when the terminal 1021 and the external conductor are selectively connected or after the terminal 1021 and the external conductor are connected, which conductor is selected and connected. Easy to grasp directly.

また,端子を内包する非充電部である外郭を把持し,それぞれの接続位置に移動させることにより,切替の際に工具を不要として,切替や接続確認における作業性を向上させるとともに,作業をする者にとって誤認を生じさせにくい回路遮断器1を提供することができる。 In addition, by gripping the outer shell, which is a non-charging part containing the terminal, and moving it to the respective connection position, no tools are required at the time of switching, improving workability in switching and connection confirmation and working. Thus, it is possible to provide a circuit breaker 1 that is less likely to cause misunderstanding for a person.

(第2の実施形態)
次に,第2の実施形態に係る回路遮断器について図5乃至図7を用いて説明する。第1の実施形態との違いは,前面a側からの平面視で前記端子並びに端子を内包する非充電部で形成される端子部202が移動する方向を器体101の幅方向とした場合に,該端子部202の移動軌跡が,それぞれの接続位置の間で器体101の幅の大きさを超えないよう端子並びに端子を内包する非充電部端子を形成していることである。
(Second Embodiment)
Next, a circuit breaker according to a second embodiment will be described with reference to FIGS. The difference from the first embodiment is that the direction in which the terminal portion 202 formed by the terminal and the non-charging portion containing the terminal moves in the plan view from the front surface a side is the width direction of the body 101. , The movement locus of the terminal portion 202 forms a terminal and a non-charging portion terminal that encloses the terminal so that the width of the container body 101 does not exceed the width of each connection position.

即ち,図5乃至図7に示したように,外部の導体とのそれぞれの接続位置において,端子部202の外郭が器体101の幅方向からはみ出ないように,端子部202の外郭は,器体101の幅方向の略半分の大きさに形成されている。 That is, as shown in FIGS. 5 to 7, the outer periphery of the terminal portion 202 does not protrude from the width direction of the container body 101 at each connection position with an external conductor. The body 101 is formed to be approximately half the size in the width direction.

また,器体101に設けられているスリット2011についても,端子部の外郭が器体の幅からはみ出ないような大きさに定められる。より詳しくは,スリット2011を設ける位置を,器体101の幅方向に対して,器体101の一方及び他方の外郭端部から,端子部202に設けられた軸(1022aと同様)の中心と端子部が位置する側の外郭までの距離から軸の外形の半分の大きさを差し引いた大きさだけ内側に設けて,端子部の外郭が器体の幅からはみ出ないように形成している。 Further, the slit 2011 provided in the container body 101 is also sized so that the outline of the terminal portion does not protrude from the width of the container body. More specifically, the position where the slit 2011 is provided is the center of the axis (similar to 1022a) provided on the terminal 202 from one and the other outer edges of the vessel 101 with respect to the width direction of the vessel 101. It is provided inside by a distance obtained by subtracting half the outer shape of the shaft from the distance to the outer shell on the side where the terminal portion is located, so that the outer shell of the terminal portion does not protrude from the width of the body.

このように回路遮断器1を構成することにより,第1の実施形態により得られる効果に加えて,端子並びに端子を内包する非充電部の移動軌跡が器体の幅の大きさを超えないため,回路遮断器を複数併設させて用いる場合においても,接続の切替作業を作業性よく行うことができる。 By configuring the circuit breaker 1 in this way, in addition to the effects obtained by the first embodiment, the movement trajectory of the terminal and the non-charging part containing the terminal does not exceed the width of the device body. Even when a plurality of circuit breakers are used together, the connection switching operation can be performed with good workability.

(第3の実施形態)
次に,第3の実施形態に係る回路遮断器について図8乃至図10を用いて説明する。第1,第2の実施形態との違いは,端子部302の配設位置を器体のより前面側とし,端子部302の裏面側に,端子部受け部1012を設けて器体を構成した点である。該端子部受け部1012は,器体101の側面から端子部302の移動軌跡に重なるように一方向に突出形成されており,回路遮断器の外郭としては,前面側から見て,端子部302が位置しない部分が凹んでいるように構成される。

Is a point. The terminal portion receiving portion 1012 is formed to project in one direction so as to overlap the movement locus of the terminal portion 302 from the side surface of the vessel body 101. As an outline of the circuit breaker, the terminal portion 302 is seen from the front side. It is comprised so that the part which is not located may be dented.

即ち,前面側から見たときに,端子部受け部1012の前面側と,器体101の端子部が設けられる側面と,端子部302の幅方向の側面とにより前面側が開放された凹み部分(図中のd)が形成されるものである。 That is, when viewed from the front side, the front side is opened by the front side of the terminal portion receiving portion 1012, the side surface on which the terminal portion of the vessel body 101 is provided, and the side surface in the width direction of the terminal portion 302 ( D) in the figure is formed.

凹み部分dは,端子部302をそれぞれの接続位置に移動させることにより,器体の幅方向において該凹み部分の現れる位置が変わり,この凹み部分には,端子とは接続されない導体が位置することになる。そして,器体の前面側から凹み部分に位置する導体を臨むことにより,端子とは接続されない導体を直接的に視認することができる。 The position of the recessed portion d is changed by moving the terminal portion 302 to each connection position, and the position where the recessed portion appears in the width direction of the body changes, and a conductor that is not connected to the terminal is located in the recessed portion. become. Then, by facing the conductor located in the recessed portion from the front side of the container, the conductor that is not connected to the terminal can be directly recognized.

また,この凹み部分をそれぞれ色分けすることにより,端子そのものの位置の違いで導体の接続状態を視認することができることに加え,導体の背景となる色合いの違いにより,より導体の接続状態の視認性が向上する。例えば,端子部302が第一の接続位置にあるとき(図11(a)の位置)の凹み部分dを緑色に着色し,第二の接続位置にあるとき(図11(b)の位置)の凹み部分dを赤色に着色する。 Also, by color-coding the dents, it is possible to visually recognize the connection state of the conductor by the difference in the position of the terminal itself, and the visibility of the connection state of the conductor is further improved by the difference in the color of the background of the conductor. Will improve. For example, when the terminal portion 302 is in the first connection position (the position in FIG. 11A), the recessed portion d is colored green and in the second connection position (the position in FIG. 11B). The indented portion d is colored red.

導体21,22と回路遮断器を接続する場合,図11(a),(b)に示したように,接続した側の導体切替前後における凹み部分の色合いが異なることにより,前面側から導体21,22に臨んだときに,接続されていない導体が視認できるとともに,色合いの違いで導体の識別性が向上する。 When connecting the conductors 21 and 22 and the circuit breaker, as shown in FIGS. 11 (a) and 11 (b), the color of the recessed portions before and after the conductor switching on the connected side is different. , 22, the unconnected conductor can be visually recognized, and the distinguishability of the conductor is improved by the difference in color.

着色の方法としては,器体101の所定部分へのシール張付けや,塗料等を塗布することによる着色,その他,器体や端子部に用いる材料に塗料を混合して材料自体に着色を行うことにより着色してもよい。 Coloring methods include sticking a seal to a predetermined portion of the container 101, coloring by applying paint, etc., and mixing the paint with the material used for the container and the terminal to color the material itself. You may color by.

本実施形態では,導体21,22における表示手段として,導体21,22の接続部近傍の表面に文字を刻印して表示手段を構成している。図12(a),(b)のように,端子部302と接続されない側の導体((a)であれば導体21,(b)であれば導体22)に表示した文字((a)であれば文字21a,(b)であれば文字22a)が器体の前面側から明確に視認できる。 In the present embodiment, as the display means in the conductors 21 and 22, the display means is configured by marking characters on the surface in the vicinity of the connection portion of the conductors 21 and 22. As shown in FIGS. 12 (a) and 12 (b), the characters ((a) displayed on the conductor on the side not connected to the terminal portion 302 (conductor 21 for (a), conductor 22 for (b)) are displayed. If there is a character 21a, if it is (b), the character 22a) can be clearly seen from the front side of the body.

表示手段としては,前述したような文字による表示の他,導体毎に図形を違えて表示することによる表示(例えば,図13に示したように,○,△,□など円や多角形による表示)や,これらの文字及び図形を着色し,互いに色を違えて設けてもよい。また,導体自体を着色してもよい。また,前述したそれぞれの凹み部における色と,それぞれの凹み部に位置する導体における文字や図形の色を合わせて着色し,視覚的に判別しやすいように色を統一させて構成してもよい。このように回路遮断器を構成することで,どの回路遮断器がどの導体を選択して接続しているのかが直接的に把握しやすく切替や接続確認における作業性を向上させることができる。 As the display means, in addition to the above-described display by characters, display by displaying different figures for each conductor (for example, display by circles, polygons such as ○, Δ, □, as shown in FIG. 13) ) Or these characters and figures may be colored and provided in different colors. Further, the conductor itself may be colored. In addition, the color of each of the recesses described above may be combined with the color of characters and figures on the conductor located in each recess, and the colors may be unified so that they can be easily visually identified. . By configuring the circuit breaker in this way, it is easy to directly grasp which circuit breaker selects and which conductor is connected, and the workability in switching and connection confirmation can be improved.

(第5の実施形態)
次に,第5の実施形態に係る回路遮断器について図14を用いて説明する。本実施形態は,前記器体101の前面側からの平面視で,端子に接続される外部の導体並びに接続されない外部の導体を直接的に視認する確認手段として,導体における前記端子との接続部近傍の前面側から見たときの裏面側に,該導体の種類を表わす表示手段を設け,器体の前面側からその表示手段を視認可能とする反射手段を設けて確認手段を形成したものである。
(Fifth embodiment)

In the present embodiment, in a plan view from the front side of the container body 101, as a confirmation means for directly visualizing an external conductor connected to a terminal and an external conductor not connected, a connecting portion of the conductor to the terminal Display means indicating the type of the conductor is provided on the back side when viewed from the front side in the vicinity, and a confirmation means is formed by providing reflection means that makes the display means visible from the front side of the container. is there.

図14に示したように,反射手段1013は,表面に光沢めっきを施した部材を端子受け部1012の前面側に,前面に対して所定の角度を持たせて斜めに配設したものである。より詳しくは,図15に示したように,導体31の裏面側に表示した表示手段を反射手段を介して前面側から視認できるよう器体101の側面cと反射面とのなす角度が約150度として構成している。なお,この角度は,導体と器体側面との距離ならびに導体と斜面との距離に応じて適宜変更しても受けるとよい。 As shown in FIG. 14, the reflecting means 1013 is a member in which a surface is subjected to gloss plating and is disposed obliquely on the front surface side of the terminal receiving portion 1012 with a predetermined angle with respect to the front surface. . More specifically, as shown in FIG. 15, the angle formed between the side surface c of the container body 101 and the reflective surface is about 150 so that the display means displayed on the back side of the conductor 31 can be viewed from the front side through the reflective means.

また,反射手段としては,材料に施す光沢めっきの他,鏡など光沢性を持つものを端子受け部1012に張付けて構成してもよい。 Further, as the reflecting means, in addition to the gloss plating applied to the material, a glossy material such as a mirror may be attached to the terminal receiving portion 1012.

このように回路遮断器を構成することにより,導体に回路遮断器を接続する前は,導体を前面側から見ても導体の種類は表示されていないが,接続を行う場合には,端子そのものの位置の違いで導体の接続状態を視認することができることに加え,接続していない導体に表示している表示手段を,器体の前面側から視認できることにより,接続しない側の導体の種類を直接的に確認することができるため接続の誤りを未然に防止でき,接続した後であっても,接続しない側の導体の種類を直接的に確認することができるため確認作業を行いやすく,接続誤りを極力少なくすることが可能である。 By configuring the circuit breaker in this way, before connecting the circuit breaker to the conductor, the type of conductor is not displayed even when the conductor is viewed from the front side. In addition to being able to visually recognize the connection status of the conductors due to the difference in position, the display means displayed on the unconnected conductors can be viewed from the front side of the container, so that the type of conductor on the unconnected side can be determined. Since it is possible to check directly, it is possible to prevent connection errors in advance, and even after connection, the type of conductor on the unconnected side can be checked directly, making it easy to check and connect. It is possible to minimize errors as much as possible.

The position of the terminal is irregular, but the circuit breaker for multiple circuit breakers depends on the display means displayed on the conductor and the position of the terminal part that is approximately half the size of the body. It is easy to directly grasp which conductor is selected and connected by the device. Further, as shown in FIGS. 18 and 19, even when a plurality of electrical acceptances according to the third embodiment are provided, the terminal positions are irregular, but the display means displayed on the conductors It is easy to know which circuit breaker is selected and connected to multiple circuit breakers by the position of the terminal part that is formed to be approximately half the size of the body. .
