Description

本発明は、たとえば分電盤内等に設置される回路遮断器に関するものである。 The present invention relates to a circuit breaker installed in, for example, a distribution board.

従来、たとえば単相三線式電路に使用される回路遮断器では、電源側端子を所謂プラグイン方式の端子として構成することがある。また、そのような回路遮断器としては、電源側端子における端子金具の位置を、本体ケース外から変更可能としたものが考案されている（たとえば特許文献１）。 BACKGROUND ART Conventionally, for example, in a circuit breaker used for a single-phase three-wire electric circuit, a power supply side terminal is sometimes configured as a so-called plug-in type terminal. Moreover, as such a circuit breaker, one in which the position of a terminal fitting on a power supply side terminal can be changed from outside the main body case has been devised (for example, Patent Document 1).

そして、上述したような端子金具１０Ａ、１０Ｂのスライド構造の組み立て及び本体ケース２への取り付けにあたっては、端子金具１０Ａを取付台１３Ａに、端子金具１０Ｂを取付台１３Ｂに夫々取り付けるとともに、リンク部材１２Ａを介して操作部材１１Ａと取付台１３Ａとを、リンク部材１２Ｂを介して操作部材１１Ｂと取付台１３Ｂとを夫々連結する。また、端子金具１０Ａ、１０Ｂが後方を向く姿勢で取付台１３Ｂの上面に取付台１３Ａを載置するとともに、操作部材１１Ａの右隣に操作部材１１Ｂを位置させて両操作部材１１Ａ、１１Ｂの軸孔１８、１８同士を一致させる。さらに、当該状態のまま軸孔１８、１８に軸部材１９を挿通させて、本体ケース２内に設けられている軸支部２６、２６に軸部材１９を軸支させるとともに、取付台１３Ａ、１３Ｂの左側面を案内凹部２３内に嵌め込み、且つ、ガイド部１６、１６の前面をガイドリブ２４の後面に当接させれば、端子金具１０Ａ、１０Ｂのスライド構造の組み立て及び本体ケース２への取り付けは完了となる。 In assembling the sliding structure of the terminal fittings 10A and 10B as described above and attaching them to the main body case 2, the terminal fittings 10A and 10B are respectively attached to the mounting base 13A and the mounting base 13B, and the link member 12A is attached to the mounting base 13B. The operating member 11A and the mounting base 13A are connected through the link member 12B, and the operating member 11B and the mounting base 13B are connected through the link member 12B. In addition, the mounting base 13A is placed on the top surface of the mounting base 13B with the terminal fittings 10A and 10B facing backward, and the operating member 11B is positioned to the right of the operating member 11A, and the shafts of both operating members 11A and 11B are The holes 18 and 18 are made to coincide with each other. Furthermore, in this state, the shaft member 19 is inserted into the shaft holes 18, 18, and the shaft member 19 is pivotally supported by the shaft supports 26, 26 provided in the main body case 2, and the mounting bases 13A, 13B are By fitting the left side surface into the guide recess 23 and bringing the front surfaces of the guide parts 16, 16 into contact with the rear surface of the guide rib 24, assembly of the sliding structure of the terminal fittings 10A, 10B and attachment to the main body case 2 are completed. becomes.

また、上述の如くして端子金具１０Ａ、１０Ｂのスライド構造を本体ケース２へ取り付けることで、本体ケース２の上面に開設されている操作窓２７内に操作面１７Ａ、１７Ｂの一部が露出する。したがって、操作窓２７を介して操作面１７Ａ、１７Ｂを操作し、左右方向を軸として操作部材１１Ａ、１１Ｂを回転させることにより、本体ケース２外から端子金具１０Ａ、１０Ｂの位置を上下方向へ変更することができる。なお、端子金具１０Ａ、１０Ｂの上下方向へのスライドは、案内凹部２３及びガイドリブ２４に案内される。 Furthermore, by attaching the sliding structure of the terminal fittings 10A and 10B to the main body case 2 as described above, a portion of the operation surfaces 17A and 17B are exposed within the operation window 27 provided on the upper surface of the main body case 2. . Therefore, by operating the operating surfaces 17A, 17B through the operating window 27 and rotating the operating members 11A, 11B about the left and right directions, the positions of the terminal fittings 10A, 10B can be changed in the vertical direction from outside the main body case 2. can do. The sliding of the terminal fittings 10A and 10B in the vertical direction is guided by the guide recesses 23 and the guide ribs 24.

端子金具１０Ａ、１０Ｂの位置調整について具体的に説明すると、入力電圧が２００Ｖである場合には、中央の端子口Ｐ２と下側の端子口Ｐ３とに端子金具１０Ａ、１０Ｂが配されている必要がある。そこで、操作部材１１Ａ、１１Ｂを回転操作して、操作面１７Ａ、１７Ｂの回転方向での中央部分が前方を向くような姿勢（操作部材１１Ａは第２回転姿勢にあり、操作部材１１Ｂは第４回転姿勢にある）とすればよい。すると、端子金具１０Ａが端子口Ｐ２の前側（第２位置）に、端子金具１０Ｂが端子口Ｐ３の前側（第３位置）に夫々配され、導電バーの端子口Ｐ２及び端子口Ｐ３への差し込みに伴い導電バーと回路遮断器１との電気的な接続が可能となる（図４、図５）。また、当該状態において取付台１３Ｂは、保持突起１４が保持凹部２５に係止しているとともに下面が本体ケース２の底面に当接した状態にある。さらに、取付台１３Ａは、保持突起１４が保持凹部２５に係止しているとともに下面が取付台１３Ｂの上面に当接した状態にある。したがって、両取付台１３Ａ、１３Ｂは、端子口Ｐ２の前側及び端子口Ｐ３の前側で夫々位置ずれすることなく保持される。また、取付台１３Ａの端子口Ｐ２を超えての下方への移動は規制される。 To specifically explain the position adjustment of the terminal fittings 10A and 10B, when the input voltage is 200V, the terminal fittings 10A and 10B must be placed between the center terminal port P2 and the lower terminal port P3. There is. Therefore, the operating members 11A and 11B are rotated so that the center portions of the operating surfaces 17A and 17B face forward (the operating member 11A is in the second rotational attitude, and the operating member 11B is in the fourth rotational attitude). (in a rotating position). Then, the terminal fitting 10A is placed in front of the terminal port P2 (second position), the terminal fitting 10B is placed in the front side of the terminal port P3 (third position), and the conductive bar is inserted into the terminal port P2 and the terminal port P3. Accordingly, electrical connection between the conductive bar and the circuit breaker 1 becomes possible (FIGS. 4 and 5). In addition, in this state, the holding protrusion 14 of the mounting base 13B is engaged with the holding recess 25, and the lower surface of the mounting base 13B is in contact with the bottom surface of the main body case 2. Furthermore, the mounting base 13A is in a state in which the holding protrusion 14 is engaged with the holding recess 25 and the lower surface is in contact with the upper surface of the mounting base 13B. Therefore, both the mounting bases 13A and 13B are held without shifting on the front side of the terminal port P2 and the front side of the terminal port P3, respectively. Further, downward movement of the mounting base 13A beyond the terminal port P2 is restricted.

また、入力電圧が１００Ｖであり、上側の端子口Ｐ１と下側の端子口Ｐ３とに導電バーが差し込まれる場合には、操作部材１１Ａ、１１Ｂを回転操作して、操作面１７Ａの回転方向での中央部分が後斜め上方を向き（操作部材１１Ａは第１回転姿勢にある）、且つ、操作面１７Ｂの回転方向での中央部分が前方を向くような姿勢（操作部材１１Ｂは第４回転姿勢にある）とすればよい。たとえば図４に示すような状態にあったとすると、操作部材１１Ａのみを回転操作することになる。すると、端子金具１０Ａが端子口Ｐ１の前側（第１位置）に、端子金具１０Ｂが端子口Ｐ３の前側（第３位置）に夫々配され、導電バーの端子口Ｐ１及び端子口Ｐ３への差し込みに伴い導電バーと回路遮断器１との電気的な接続が可能となる（図６）。また、当該状態において取付台１３Ｂは、保持突起１４が保持凹部２５に係止しているとともに下面が本体ケース２の底面に当接した状態にある。さらに、取付台１３Ａは、保持突起１４が保持凹部２５に係止しているとともに上面が本体ケース２の上面に当接した状態にある。したがって、両取付台１３Ａ、１３Ｂは、端子口Ｐ１の前側及び端子口Ｐ３の前側で夫々位置ずれすることなく保持される。 In addition, when the input voltage is 100V and a conductive bar is inserted into the upper terminal port P1 and the lower terminal port P3, the operating members 11A and 11B are rotated to rotate the operating surface 17A in the rotational direction. The central part of the operating surface 17B faces diagonally upward rearward (the operating member 11A is in the first rotational position), and the central part of the operating surface 17B in the rotational direction faces forward (the operating member 11B is in the fourth rotational position). ) can be used. For example, if the state is as shown in FIG. 4, only the operating member 11A will be rotated. Then, the terminal fitting 10A is placed in front of the terminal port P1 (first position), the terminal fitting 10B is placed in the front side of the terminal port P3 (third position), and the conductive bar is inserted into the terminal port P1 and the terminal port P3. Accordingly, electrical connection between the conductive bar and the circuit breaker 1 becomes possible (FIG. 6). In addition, in this state, the holding protrusion 14 of the mounting base 13B is engaged with the holding recess 25, and the lower surface of the mounting base 13B is in contact with the bottom surface of the main body case 2. Furthermore, the mounting base 13A is in a state in which the holding protrusion 14 is engaged with the holding recess 25 and the upper surface is in contact with the upper surface of the main body case 2. Therefore, both the mounting bases 13A and 13B are held without shifting on the front side of the terminal port P1 and the front side of the terminal port P3, respectively.

また、入力電圧が１００Ｖであり、上側の端子口Ｐ１と中央の端子口Ｐ２とに導電バーが差し込まれる場合には、操作部材１１Ａ、１１Ｂを回転操作して、操作面１７Ａ、１７Ｂの回転方向での中央部分が後斜め上方を向くような姿勢（操作部材１１Ａは第１回転姿勢にあり、操作部材１１Ｂは第３回転姿勢にある）とすればよい。たとえば図４に示すような状態にあったとすると、両操作部材１１Ａ、１１Ｂを回転操作することになる。すると、端子金具１０Ａが端子口Ｐ１の前側（第１位置）に、端子金具１０Ｂが端子口Ｐ２の前側（第２位置）に夫々配され、導電バーの端子口Ｐ１及び端子口Ｐ２への差し込みに伴い導電バーと回路遮断器１との電気的な接続が可能となる（図７）。また、当該状態において取付台１３Ｂは、保持突起１４が保持凹部２５に係止した状態にある。さらに、取付台１３Ａは、保持突起１４が保持凹部２５に係止しているとともに下面が取付台１３Ｂの上面に当接した状態にある。したがって、両取付台１３Ａ、１３Ｂは、端子口Ｐ１の前側及び端子口Ｐ２の前側で夫々位置ずれすることなく保持される。また、取付台１３Ｂの端子口Ｐ２を超えての上方への移動は規制される。 In addition, when the input voltage is 100V and a conductive bar is inserted into the upper terminal port P1 and the center terminal port P2, the operating members 11A and 11B are rotated to rotate the operating surfaces 17A and 17B. The central portion thereof may face diagonally upward rearward (the operating member 11A is in the first rotational attitude, and the operating member 11B is in the third rotational attitude). For example, if the state is as shown in FIG. 4, both operating members 11A and 11B will be rotated. Then, the terminal fitting 10A is placed in front of the terminal port P1 (first position), the terminal fitting 10B is placed in the front side of the terminal port P2 (second position), and the conductive bar is inserted into the terminal port P1 and the terminal port P2. Accordingly, electrical connection between the conductive bar and the circuit breaker 1 becomes possible (FIG. 7). Further, in this state, the mounting base 13B is in a state where the holding protrusion 14 is locked in the holding recess 25. Furthermore, the holding protrusion 14 of the mounting base 13A is engaged with the holding recess 25, and the lower surface of the mounting base 13A is in contact with the upper surface of the mounting base 13B. Therefore, both the mounting bases 13A and 13B are held without shifting on the front side of the terminal port P1 and the front side of the terminal port P2, respectively. Further, upward movement of the mounting base 13B beyond the terminal port P2 is restricted.
