Description

本発明は、配線用遮断器などを対象とする回路遮断器に追加装備してその本体ケースの内部に格納するカセット式の内部付属装置の構造に関する。   The present invention relates to a structure of a cassette-type internal accessory device that is additionally provided in a circuit breaker intended for a wiring breaker and the like and is stored inside the main body case.

周知のように頭記の回路遮断器には、仕様変更に対してフレキシブルに対応させるように補助スイッチ，警報スイッチ，電圧引外し装置，不足電圧引外し装置などの各種付属装置が用意されている。 また、前記の内部付属装置を遮断器の本体ケースに後付けして搭載するために、本体ケースの内方にはポケット状の付属品収納部を画成しておき、ここに付属装置をカセット式に格納した上で、付属装置のリード線を本体ケースから外部に引き出して盤内に配備した回路遮断器の動作表示部，制御部などに配線するようにしている。
次に、前記の補助スイッチと警報スイッチを組合せた付属装置を例に、付属装置の従来構造および該付属装置を搭載する回路遮断器の本体ケースの構造を図５〜図８に示す。まず、図５は回路遮断器（配線用遮断器）の外観図で、１は遮断器本体のケース、２はカバー、３はカバー２の上面に付設した開閉式のトップカバー、４は開閉操作ハンドルであり、図示してないが本体ケース内にはＲ，Ｓ，Ｔ相の各相に対応する主回路接点、開閉機構、過電流引外し装置などの機能部品を装備している。 As is well known, the circuit breakers mentioned above are equipped with various auxiliary devices such as auxiliary switches, alarm switches, voltage trip devices, undervoltage trip devices, etc., so as to respond flexibly to specification changes. . In addition, in order to retrofit and mount the internal accessory device on the main body case of the circuit breaker, a pocket-shaped accessory storage part is defined inside the main body case, and the accessory device is cassette-type here. Then, the lead wire of the accessory device is pulled out from the main body case and wired to the operation display unit, control unit, etc. of the circuit breaker installed in the panel.
Next, taking as an example an accessory device in which the auxiliary switch and the alarm switch are combined, the conventional structure of the accessory device and the structure of the main body case of the circuit breaker mounting the accessory device are shown in FIGS. 5 is an external view of a circuit breaker (wiring breaker). 1 is a case of a circuit breaker body, 2 is a cover, 3 is an openable top cover attached to the upper surface of the cover 2, and 4 is an opening / closing operation. Although not shown, the main body case is equipped with functional parts such as a main circuit contact corresponding to each of the R, S, and T phases, a switching mechanism, and an overcurrent trip device.

また、図６に示す付属装置５は、カセット構造のベース（樹脂成形品）６に補助スイッチ，警報スイッチに対応する２個のマイクロスイッチ７を並置して組み込み、かつベース６の一端側に係合爪を兼ねた把手６ａを、他端側には補助スイッチの操作レバー８および警報スイッチの操作レバー９を組み付けた上で、各スイッチの端子に半田付け接合したリード線１０をベース６の上面側から引き出した構造になる。
一方、上記付属装置５を搭載する遮断器本体ケースのカバー２には、図７で示すようにハンドルの装着位置を挟んでその両サイドにポケット状の付属品収納部２ａが画成されており、付属装置５をこの収納部２ａに上方から挿入セットし、図８に示した組み込み位置で前記した操作レバー８，９を遮断器本体の開閉機構にそれぞれ連繋させて遮断器のＯＮ，ＯＦＦ状態，およびトリップ動作状態を検知するようにしている。なお、図８においてトップカバー３は一端をカバー２にヒンジ結合しており、通常の使用状態では図５のようにトップカバー３を閉じて前記付属装置５を覆っている。 In addition, the attachment device 5 shown in FIG. 6 includes two micro switches 7 corresponding to auxiliary switches and alarm switches arranged in parallel on a cassette-structure base (resin molded product) 6 and is connected to one end of the base 6. A handle 6a that also serves as a catch is assembled with an operation lever 8 for an auxiliary switch and an operation lever 9 for an alarm switch on the other end, and a lead wire 10 soldered to a terminal of each switch is connected to the upper surface of the base 6. The structure is drawn from the side.
On the other hand, as shown in FIG. 7, the cover 2 of the circuit breaker body case on which the accessory device 5 is mounted has pocket-shaped accessory storage portions 2a on both sides of the handle mounting position. The accessory device 5 is inserted and set into the storage portion 2a from above, and the operation levers 8 and 9 are connected to the open / close mechanism of the circuit breaker at the assembly position shown in FIG. , And trip operation status are detected. In FIG. 8, one end of the top cover 3 is hinged to the cover 2, and the top cover 3 is closed to cover the attachment device 5 as shown in FIG.

また、付属装置５を遮断器本体に組み込んだ状態では、図６に示したリード線１０を本体ケースのカバー２とトップカバー３との間に形成されているリード引き出し用の隙間を通じてケース外方に引き出して配線するようにしているが、この場合にリード線１０が外力を受けて付属装置の接続部（半田付け）から離脱しないようリード線１０を結束した状態で遮断器の本体ケース側に保持する必要があり、この結束保持手段として遮断器ケースの左右側壁部分に独立部品になるリード線保持具を着脱可能に装着し、この保持具に嵌挿して付属装置に接続したリード線をケース外方に引き出すようにした構成のものが知られている（例えば、特許文献１参照）。
特許第３４８２３０２号公報 Further, in the state where the accessory device 5 is incorporated in the circuit breaker body, the lead wire 10 shown in FIG. 6 is placed outside the case through the lead lead-out gap formed between the cover 2 and the top cover 3 of the body case. In this case, the lead wire 10 is bound to the main body case side of the circuit breaker in a state in which the lead wire 10 is bound so that the lead wire 10 is not detached from the connecting portion (soldering) of the accessory device due to external force. It is necessary to hold the lead wire holder as an independent part on the left and right side wall parts of the circuit breaker case as detachable holding means, and the lead wire inserted into this holder and connected to the accessory device is attached to the case. The thing of the structure made to pull out outward is known (for example, refer patent document 1).
Japanese Patent No. 3482302

前記特許文献１に開示されているリード線保持具を用いることにより、図８のように遮断器ケースカバー２の左側収納部，右側収納部に収納したいずれの付属装置に対しても同じ部品のリード線保持具で対応できる利便性がある反面、リード線保持具が独立した小型部品であることからユーザーサイドで付属装置を後付けする場合に部品を紛失したりするおそれがあって保管管理が煩わしいほか、付属装置とは別に前記リード線保持具を遮断器ケースに装着するために手間がかかる。また、付属装置のリード線は付属装置のセット位置により遮断器ケースから左右サイドに引き出すほか、仕様によっては遮断器ケースの電源側サイドに引き出して配線する場合もあるが、前記したリード保持具は遮断器ケースの側壁に取り付けるため、このような配線には対応できない問題もある。
本発明は上記の点に鑑みなされたものであり、その目的は前述のように独立部品になるリード線保持具を用いることなく、遮断器ケースに付属装置を装着した状態でリード線を結束保持して左右，電源側のいずれのサイドへの引き出しにも対応できるようにして配線作業の利便性を高めた回路遮断器の内部付属装置を提供することにある。 By using the lead wire holder disclosed in Patent Document 1, the same components can be used for any accessory device stored in the left storage portion and the right storage portion of the circuit breaker case cover 2 as shown in FIG. While it is convenient to handle with the lead wire holder, the lead wire holder is an independent small part, so there is a risk of losing the part when attaching the attached device on the user side, and storage management is troublesome In addition, it takes time to mount the lead wire holder on the circuit breaker case separately from the attached device. In addition to pulling out the lead wire of the accessory device from the circuit breaker case to the left and right sides depending on the set position of the accessory device, depending on the specifications, the lead wire may be pulled out and wired to the power supply side of the circuit breaker case. Since it attaches to the side wall of a circuit breaker case, there also exists a problem which cannot respond to such wiring.
The present invention has been made in view of the above points, and the object thereof is to hold the lead wires in a state where the accessory device is mounted on the circuit breaker case without using the lead wire holder which becomes an independent part as described above. Accordingly, it is an object of the present invention to provide an internal auxiliary device for a circuit breaker that can be pulled out to either the left or right side or the power source side, thereby improving the convenience of wiring work.

上記目的を達成するために、本発明によれば、遮断器の本体ケース内部に画成したポケット状の付属品収納部に格納して遮断器本体の開閉機構に連繋させたカセット式の内部付属装置で、そのベースに組み込んだ機能部品に接続したリード線を結束して前記本体ケースの外方に引き出して配線するようにしたものにおいて、
前記ベースの左右側壁面に、機能部品のリード線を嵌挿して結束状態に保持するリード線保持部を設けるものとし（請求項１）、そのリード線保持部は具体的に次記のような態様で構成する。
（１）前記のリード線保持部がベース側壁から突き出したＴ字形のアームとし、該アームの両サイドからアームとベース側壁との間の隙間にリード線を嵌入して結束状態に保持するようにする（請求項２）。
（２）前項（１）において、Ｔ字形アームの先端部にリード線の抜け止め防止用の突起を設ける（請求項３）。
（３）前記のリード線保持部に保持したリード線を内部付属装置のベース側壁面に沿って電源側に引き出すようにする（請求項４）。 To achieve the above object, according to the present invention, a cassette-type internal accessory housed in a pocket-shaped accessory storage section defined in the main body case of the circuit breaker and linked to the opening / closing mechanism of the circuit breaker main body. In the device, in which the lead wire connected to the functional component incorporated in the base is bundled and pulled out to the outside of the main body case for wiring,
Provided on the left and right side wall surfaces of the base are lead wire holding portions for inserting and holding the lead wires of the functional parts in a bundled state (Claim 1), and the lead wire holding portions are specifically as described below. It is comprised in an aspect.
(1) The lead wire holding portion is a T-shaped arm protruding from the base side wall, and the lead wire is inserted into the gap between the arm and the base side wall from both sides of the arm so as to be held in a bundled state. (Claim 2).
(2) In the preceding item (1), a protrusion for preventing the lead wire from coming off is provided at the tip of the T-shaped arm.
(3) The lead wire held in the lead wire holding portion is pulled out to the power supply side along the base side wall surface of the internal accessory device.

上記の構成によれば、付属装置に対して機能部品を組み付けたベースの左右側壁面にリード線保持部としてＴ字形のアームをあらかじめ設けたことにより、特許文献１に開示されている構成のように、付属装置と別個の独立部品になるリード線保持具を必要とせずに、付属装置に設けたリード線保持部を選択することで、遮断器ケースから左右，あるいは電源側サイド方向へのリードの引き出しにも対応してリード線を結束した状態に保持することができる。また、ベース６の両側壁に沿ってリード線を引き外すため、付属装置の外形寸法が大型化することもない。これにより、ユーザーサイドで付属装置を遮断器に後付けする場合でも、リード線の配線作業を簡単に行うことができて利便性が向上する。   According to the above configuration, the T-shaped arm as the lead wire holding portion is provided in advance on the left and right side wall surfaces of the base in which the functional parts are assembled to the accessory device, so that the configuration disclosed in Patent Document 1 is obtained. In addition, by selecting the lead wire holder provided in the accessory device without the need for a lead wire holder that is an independent component separate from the accessory device, the lead from the circuit breaker case to the left or right or the power supply side The lead wire can be held in a bundled state corresponding to the drawing of the wire. In addition, since the lead wires are pulled off along both side walls of the base 6, the external dimensions of the accessory device are not increased. Thus, even when the user attaches the attached device to the circuit breaker, the lead wire can be easily wired and the convenience is improved.

以下、本発明の実施の形態を図１〜図４に示す実施例に基づいて説明する。なお、実施例の図中で図５〜図８に対応する部材には同じ符号を付してその詳細な説明は省略する。
まず、先記した図６の付属装置と同様に付属スイッチと警報スイッチを組み合わせてユニット化した付属装置を例に、本発明の実施例による付属装置の構造を図１（ａ）に示す。すなわち、図示実施例の付属装置は図６の構成と基本的に同様であるが、補助スイッチ７ａ，警報スイッチ７ｂに対応する機能部品を組み付けたモールド樹脂製のベース（カセット容器）６には、その左右の側壁面から側方に張り出したリード線保持部６ｃが一体成形されている。このリード線保持部６ｃはＴ字形のアームになり、そのアームとベース側壁面との間にはアームの中央脚部6c−２を境にしてその両側に、リード線１０をアームの先端側から嵌挿して結束状態に保持するよう両端が開放した隙間が画成されている。また、アームの先端には前記隙間を狭めてリード線外れを防止する抜け止め突起６ｃ−１が形成されている。なお、６ｂはリード線１０の押え板を兼ねたベース６の上蓋である。 Embodiments of the present invention will be described below based on the examples shown in FIGS. In addition, in the figure of an Example, the same code | symbol is attached | subjected to the member corresponding to FIGS. 5-8, and the detailed description is abbreviate | omitted.
First, FIG. 1A shows the structure of an accessory device according to an embodiment of the present invention, taking as an example an accessory device in which an accessory switch and an alarm switch are combined into a unit in the same manner as the accessory device in FIG. That is, the attached device of the illustrated embodiment is basically the same as the configuration of FIG. 6, but the base (cassette container) 6 made of molded resin assembled with functional parts corresponding to the auxiliary switch 7 a and the alarm switch 7 b is Lead wire holding portions 6c projecting laterally from the left and right side wall surfaces are integrally formed. The lead wire holding portion 6c is a T-shaped arm, and between the arm and the base side wall surface, the lead wire 10 is provided from both ends of the arm at the central leg portion 6c-2. A gap with both ends open is defined so as to be inserted and held in a bundled state. Also, a retaining protrusion 6c-1 is formed at the tip of the arm to narrow the gap and prevent the lead wire from coming off. Reference numeral 6b denotes an upper cover of the base 6 which also serves as a holding plate for the lead wire 10.

上記の構成で、付属装置５の付属スイッチ７ａおよび警報スイッチ７ｂの端子に半田接合したリード線１０を、図中の矢印Ｐ方向から見てベース６の右側面に設けたリード線保持部６ｃのＴ字形アームに保持するには、図示のように合計６本のリード線１０をスイッチ別に３本ずつグループ分けした上で、補助スイッチ７ａのリード線１０ａを矢印Ｐと同じ方向から１本ずつ前記隙間に押し込んで嵌挿する。また、警報スイッチ７ｂのリード線１０ｂは矢印Ｐと反対方向から嵌挿する。これにより、Ｔ字形アームの中央支脚６ｃ−２を境に左側にリード線１０ａが、右側にはリード線１０ｂがそれぞれ保持される。
また、前記のリード線１０を図１（ａ）とは反対側のサイドに引き出す場合には、図２のように補助スイッチ７ａ，警報スイッチ７ｂにそれぞれ接続したリード線１０ａ，１０ｂをグループ分けした上で、図示矢印Ｐ方向から見てベース６の左側面に設けたリード線保持部６ｃのＴ字形アームとベース側壁との間の隙間に嵌挿して保持する。 With the above configuration, the lead wire 10 soldered to the terminals of the accessory switch 7a and the alarm switch 7b of the accessory device 5 is connected to the lead wire holding portion 6c provided on the right side surface of the base 6 when viewed from the direction of arrow P in the figure. In order to hold the T-shaped arm, a total of six lead wires 10 are grouped in groups of three for each switch as shown in the figure, and the lead wires 10a of the auxiliary switch 7a are one by one from the same direction as the arrow P. Push into the gap and insert. The lead wire 10b of the alarm switch 7b is inserted from the direction opposite to the arrow P. As a result, the lead wire 10a is held on the left side and the lead wire 10b is held on the right side with the center support leg 6c-2 of the T-shaped arm as a boundary.
When the lead wire 10 is pulled out to the side opposite to FIG. 1A, the lead wires 10a and 10b connected to the auxiliary switch 7a and the alarm switch 7b are grouped as shown in FIG. Above, it is inserted and held in the gap between the T-shaped arm of the lead wire holding portion 6c provided on the left side surface of the base 6 and the side wall of the base 6 when viewed from the direction of the arrow P.

そして、上記のような手順でリード線１０をリード線保持部６ｃに結束保持した付属装置５を、そのリード線１０の引き出し方向に合わせて遮断器ケースのカバー２の左右両サイドに画成したポケット状の付属品収納部（図７参照）に収納してセットする。図１（ｂ）は２組の付属装置５を左右に分けて遮断器ケースのカバー２に収納セットした状態を表しており、各付属装置５のリード線１０はそれぞれカバー２とトップカバー３との間の隙間を通じて本体ケースの左右サイドから側方に引き出されている。
次に、遮断器ケースに搭載した付属装置５について、補助スイッチ７ａ，警報スイッチ７ｂのリード線１０を本体ケースの電源側サイド（図５参照）に引き出す配線について説明する。この場合には図３で示すように、補助スイッチ７ａのリード線１０ａは矢印Ｐ方向から見てベース６の右側面のリード線保持部６ｃに嵌挿保持した上で、ベース６の側面に沿って引き出し、警報スイッチ７ｂのリード線１０ｂは前記と反対側のリード線保持部６ｃに嵌挿保持して引き出すようにする。図４はこのようにして遮断器ケースのカバー２に搭載した付属装置５のリード線１０を電源側サイドに引き出した状態を表している。この場合でも、付属装置５から引き出したリード線１０はリード線保持部６ｃに保持されているので、外部からリード配線を引っ張ってもリード線が抜けるおそはない。また、ベース６の両側壁に沿ってリード線を引き外すため、付属装置の外形寸法が大型化することもない。なお、図示実施例では補助スイッチと警報スイッチを組み合わせた付属装置について述べたが、電圧引外し装置，不足電圧引外し装置などの付属装置についても同様に実施できることは勿論である。 Then, the accessory device 5 in which the lead wire 10 is bound and held by the lead wire holding portion 6c in the above-described procedure is defined on both the left and right sides of the cover 2 of the circuit breaker case in accordance with the lead-out direction of the lead wire 10.

Lead wires 10 of the attachment devices 5 are respectively connected to the cover 2 and the top cover 3. It is pulled out to the side from the left and right sides of the main body case through a gap between them.
Next, with regard to the accessory device 5 mounted on the circuit breaker case, wiring for drawing out the lead wires 10 of the auxiliary switch 7a and the alarm switch 7b to the power supply side of the main body case (see FIG. 5) will be described. In this case, as shown in FIG. 3, the lead wire 10 a of the auxiliary switch 7 a is fitted and held in the lead wire holding portion 6 c on the right side surface of the base 6 when viewed from the direction of the arrow P, and then along the side surface of the base 6. The lead wire 10b of the alarm switch 7b is inserted and held in the lead wire holding portion 6c on the opposite side to the above to be pulled out. FIG. 4 shows a state in which the lead wire 10 of the accessory device 5 mounted on the cover 2 of the circuit breaker case is pulled out to the power supply side. Even in this case, since the lead wire 10 pulled out from the attachment device 5 is held by the lead wire holding portion 6c, the lead wire is not likely to come out even if the lead wiring is pulled from the outside. In addition, since the lead wires are pulled off along both side walls of the base 6, the external dimensions of the accessory device are not increased. In the illustrated embodiment, an auxiliary device combining an auxiliary switch and an alarm switch has been described. Needless to say, the auxiliary device such as a voltage trip device and an undervoltage trip device can be implemented in the same manner.
