Description

本発明は、分電盤に搭載され、端子部を銅バー等で接続されるプラグイン式配線用遮断器に関するものである。   The present invention relates to a plug-in type circuit breaker mounted on a distribution board and connected to a terminal portion with a copper bar or the like.

従来技術におけるプラグイン式配線用遮断器では、可動端子は上下にスライド移動可能に設けられ、可動端子を下側に押し込んで位置を変え、電圧切り換えをするものであった。   In the plug-in type circuit breaker in the prior art, the movable terminal is provided to be slidable up and down, and the voltage is switched by pushing the movable terminal downward to change the position.

しかしながら、上記プラグイン式配線用遮断器では、省スペースではあるが、２００Ｖに設定した場合の絶縁距離が１００Ｖに設定した場合の絶縁距離に比べて小さくなり、十分な絶縁距離がとれているとは言え、可能な限り端子を離しておきたいという要望があった。   However, in the above plug-in type circuit breaker, although the space is saved, the insulation distance when set to 200V is smaller than the insulation distance when set to 100V, and a sufficient insulation distance is taken. Nevertheless, there was a desire to keep the terminals as far as possible.

そこで、プラグイン式配線用遮断器の可動端子を１８０度回転させて２００Ｖと１００Ｖとの設定を変更することができる。
特開２０００−２２２９９７号公報 特開２００２−１９９５１４号公報 Therefore, the setting of 200 V and 100 V can be changed by rotating the movable terminal of the plug-in type circuit breaker by 180 degrees.
JP 2000-2222997 A JP 2002-199514 A

特開２００２−１９９５１４号では、可動端子を１８０度回転させて電圧の変更を行うため、１００Ｖの場合に比べて２００Ｖの場合には絶縁距離が大きく取れるが、端子部に可動端子を回転させるだけのスペースが必要となり、端子部が大きくなるという欠点がある。   In Japanese Patent Laid-Open No. 2002-199514, since the voltage is changed by rotating the movable terminal by 180 degrees, the insulation distance can be increased in the case of 200 V compared with the case of 100 V, but only the movable terminal is rotated in the terminal portion. Space is required, and there is a disadvantage that the terminal portion becomes large.

本発明は、省スペースで電圧切り換えが容易であるプラグイン式配線用遮断器を提供することを目的とし、その構造は、遮断器短手側面に端子が設けられ、該端子は前記側面の略中央部に固定端子を、該固定端子の上方に可動端子を設けると共に、該可動端子は回転軸を中心に回動可能であり、前記固定端子の回転軸を中心として反対側と、その位置から９０度回転した位置とで固定可能であることを特徴とする。   An object of the present invention is to provide a plug-in-type circuit breaker that is space-saving and can be easily switched in voltage, and has a structure in which a terminal is provided on the short side of the circuit breaker, and the terminal is an abbreviation of the side. A fixed terminal is provided at the center, and a movable terminal is provided above the fixed terminal. The movable terminal is rotatable about a rotation axis. From the position opposite to the rotation axis of the fixed terminal and the position thereof. It can be fixed at a position rotated by 90 degrees.

本発明のプラグイン式配線用遮断器は、可動端子を９０度回転させることで電圧の切り換えができ、容易であると共に、端子部の配置が省スペースでありながら、十分な絶縁距離も確保できるという利点がある。   The plug-in type circuit breaker according to the present invention can easily change the voltage by rotating the movable terminal by 90 degrees, and can easily secure a sufficient insulation distance while the space for the terminal portion is small. There is an advantage.

電圧の切り換え作業が容易であり、端子を省スペースに配置するという目的を、最小の部品点数で、絶縁距離を確保したまま実現した。   The voltage switching operation is easy and the purpose of arranging the terminals in a space-saving manner has been realized with a minimum number of parts and an insulation distance.

本発明に係るプラグインイン式配線用遮断器の実施例を図１〜図２の添付図面に基づいて説明する。   An embodiment of a plug-in type circuit breaker according to the present invention will be described with reference to the accompanying drawings of FIGS.

単相３線式の分電盤においては、主幹銅バーが３本敷設され、３本の主幹銅バーのうちのいずれか２本を選択することのより、２００Ｖもしくは１００Ｖの電圧の切り換えを行う。   In the single-phase three-wire distribution board, three main copper bars are installed, and switching between 200V and 100V is performed by selecting any two of the three main copper bars. .

プラグイン式配線用遮断器１の短手側面の端子部２に端子３を設ける。端子３は、主幹銅バー４が挿入可能である挿入孔５を設け、挿入孔５奥には受け刃６を備える。端子３は、端子部２の略中央部に固定される固定端子３ａと、回動動作により位置が変更可能である可動端子３ｂとを設ける。端子部の前面カバー７は取り外し可能であり、可動端子３ｂを回転させるときには取り外す。可動端子３ｂは、回転軸を中心に上方から側方へ移動できる。   The terminal 3 is provided in the terminal part 2 of the short side surface of the circuit breaker 1 for plug-in wiring. The terminal 3 is provided with an insertion hole 5 into which the main copper bar 4 can be inserted, and a receiving blade 6 is provided behind the insertion hole 5. The terminal 3 is provided with a fixed terminal 3a fixed to a substantially central portion of the terminal portion 2 and a movable terminal 3b whose position can be changed by a rotating operation. The front cover 7 of the terminal portion is removable, and is removed when the movable terminal 3b is rotated. The movable terminal 3b can move from the upper side to the side around the rotation axis.

３本の主幹銅バー４のうち２本は水平に、１本は垂直に敷設する。固定端子３ａには水平に配置された主幹銅バー４ａを挿入する。固定端子３ａに挿入された主幹銅バー４ａとは別の主幹銅バー４ｂに可動端子３ｂを接続するために、可動端子３ｂは、回転軸８を中心に固定端子３ａと反対側の位置に固定する。電圧が高くなるほど、絶縁距離を多く取った方がより安全であるため、遠くの端子を接続したとき、例えば、固定端子３ａに下部銅バー４ａを、可動端子３ｂは上方に固定し上部銅バー４ｂを接続すると２００Ｖとなる。   Of the three main copper bars 4, two are laid horizontally and one is laid vertically. A main copper bar 4a arranged horizontally is inserted into the fixed terminal 3a. In order to connect the movable terminal 3b to the main copper bar 4b different from the main copper bar 4a inserted into the fixed terminal 3a, the movable terminal 3b is fixed at a position opposite to the fixed terminal 3a around the rotation shaft 8. To do. As the voltage increases, it is safer to increase the insulation distance. Therefore, when connecting a distant terminal, for example, the lower copper bar 4a is fixed to the fixed terminal 3a, and the movable terminal 3b is fixed to the upper copper bar. When 4b is connected, it becomes 200V.

可動端子３ｂを下部銅バー４ｂに対向させてプラグイン式配線用遮断器１の下側に固定した状態から、可動端子３ｂは固定位置を変更することができる。前面カバー７を外し、上部に水平に配置されていた可動端子３ｂを９０度回転させ垂直に配置された銅バー３ｃに対向させる。固定端子３ａに下部銅バー４ａを、可動端子３ｂは中間位置に固定し中間銅バー４ｃを接続すると１００Ｖとなる。   From the state in which the movable terminal 3b is fixed to the lower side of the plug-in wiring circuit breaker 1 so as to face the lower copper bar 4b, the fixed position of the movable terminal 3b can be changed. The front cover 7 is removed, and the movable terminal 3b arranged horizontally at the upper part is rotated 90 degrees so as to face the copper bar 3c arranged vertically. When the lower copper bar 4a is fixed to the fixed terminal 3a and the movable terminal 3b is fixed at an intermediate position and the intermediate copper bar 4c is connected, the voltage becomes 100V.

また、本発明に係るプラグイン式配線用遮断器は、上記配置に限定されるものではなく、本発明の趣旨を逸脱しない範囲において適宜変更可能である。   Further, the plug-in type circuit breaker according to the present invention is not limited to the above arrangement, and can be appropriately changed without departing from the gist of the present invention.

図３に示すように、特に端子部の省スペースを図りたい場合には、固定端子９ａに下部銅バー１０ａを、可動端子９ｂは中間位置に固定し中間銅バー１０ｃを接続すると２００Ｖに、また、固定端子９ａに下部銅バー１０ａを、可動端子９ｂは上方に固定し上部銅バー１０ｂを接続すると１００Ｖになるようにしてもよい。   As shown in FIG. 3, particularly when it is desired to save space in the terminal portion, the lower copper bar 10a is fixed to the fixed terminal 9a, the movable terminal 9b is fixed at an intermediate position, and the intermediate copper bar 10c is connected to 200V. The lower copper bar 10a may be fixed to the fixed terminal 9a, the movable terminal 9b may be fixed upward, and the upper copper bar 10b may be connected to be 100V.

例えば、図４に示すように、主幹銅バー１１のうち下部銅バー１１ｂと中間銅バー１１ｃと垂直に、上部銅バー１１ａは水平に配置し、それに対向させて端子１２を配置する。固定端子１２ａを垂直に、可動端子１２ｂは上部に配置するときには水平に、電圧切り換えにより９０度回転させたとき、垂直になるように配置する。   For example, as shown in FIG. 4, among the main copper bars 11, the upper copper bar 11a is disposed horizontally, perpendicularly to the lower copper bar 11b and the intermediate copper bar 11c, and the terminals 12 are disposed opposite thereto. The fixed terminal 12a is arranged vertically, and the movable terminal 12b is arranged horizontally when arranged at the top, and arranged vertically when rotated 90 degrees by voltage switching.

また、図５に示すように、主幹銅バー１３のうち下部銅バー１３ａと上部銅バー１３ｂとを垂直に、中間銅バー１３ｃ配置し、それに対向させて端子１４を配置する。固定端子１４ａは下部に垂直に、可動端子１４ｂは上部に固定される場合には垂直に、電圧切り換えにより９０度回転させたとき、水平になるように配置する。   Further, as shown in FIG. 5, the lower copper bar 13 a and the upper copper bar 13 b of the main copper bar 13 are arranged vertically, the intermediate copper bar 13 c is arranged, and the terminals 14 are arranged so as to face each other. The fixed terminal 14a is vertically arranged at the bottom, and the movable terminal 14b is vertically arranged when it is fixed at the top, and is arranged so as to be horizontal when rotated 90 degrees by voltage switching.

また、図６に示すように、主幹銅バー１５のうち下部銅バー１５ａと上部銅バー１５ｂとを水平に配置し、中間銅バー１５ｃは垂直に配置する。それに対向させて端子１６を配置する。固定端子１６ａを上部に水平に配置し、上部に可動端子１６ｂを水平に配置する。可動端子１６ｂを電圧切り換えにより９０度回転させたとき、垂直になるように配置する。   Further, as shown in FIG. 6, the lower copper bar 15 a and the upper copper bar 15 b of the main copper bar 15 are arranged horizontally, and the intermediate copper bar 15 c is arranged vertically. The terminal 16 is arranged to face it. The fixed terminal 16a is horizontally arranged at the top, and the movable terminal 16b is horizontally arranged at the top. When the movable terminal 16b is rotated 90 degrees by voltage switching, it is arranged so as to be vertical.

端子部を可動にすることによって、容易に電圧の切り換えが行え、しかも、回転角度も９０度で良いので、省スペースを図ることができる。   By making the terminal portion movable, the voltage can be easily switched and the rotation angle can be 90 degrees, so that space can be saved.
