図に示す状態より４上方に上らないようにされている。A conventional example is shown in FIGS. 1 and 2. In the figure, fl) is a movable contact, which is equipped with a movable contact on the upper surface of one end, and a rotating shaft (8) is attached approximately in the center in a direction perpendicular to the longitudinal direction. The two ends of vertically extending elongated holes (@) K provided in the nine pairs of protrusions 9 and 4, which stand upright from the frame (8), are inserted into the sliding contact +1). Not only is it rotatable, but it can also be slid in the vertical direction within the range of the four elongated holes (6). The other end of the movable contactor (1) can be freely engaged with the upper part of a latch lever fI whose center portion is rotatably supported by a shaft C121 on a protruding piece Q4 extending from the frame (8). A coiled AM spring (4) is disposed between the shaft 13) and the other end of the frame (a), and the other end of the movable contact (1) moves upward. The bullet is energized. Qη is fixed through the frame (8) and has a round iron core (
A coil that is a IIK temple turn is heated, one end is connected to the terminal O@,
The other end is connected to the movable contact Tl) via 1Iasn, and the movable contact f1) is connected to its movable contact (2
) and a fixed contact (9) to the terminal -. The lower end of the latch lever II) faces one end of the iron core 914, and is attracted to the iron core O by the magnetic attraction force generated when a large current flows through the coil αη, and the latch lever ( When the hot water) rotates, the latch lever (5)
) and the movable contact (1) become uncoupled and the opening spring (4)
The movable contact (1) rotates when replaced by K, and the fixed contact +9
A (11) is a reset button that disconnects the movable contact (11) from the opening spring (4).
The display button rotates against the latch lever (6) to re-engage with the latch lever (6), and is constantly biased downward by a spring to prevent the movement of the movable contact 11). According to 6
It changes the amount of central output from between the bodies and displays whether it is in an on state or has tripped. *, this display button - is the second
It is designed not to rise 4 degrees above the state shown in the figure.

The rotating shaft (3) is inserted through the elongated hole 1111K so that it can move up and down in the vertical direction, that is, in the operating direction of the contact part. However, in order to ensure this OT, the gap 1 between the rotating shaft (1) and the elongated hole (one end of the hole) that occurs in the closed state is the conventional method.

。従って直流回路において１０００人というような高ア
シペア時の遮断性能がややａｙｓという問題点を有して
いた。In the example, this is a factor that makes it impossible to increase the contact distance l after opening. As shown in Fig. 2, when the contact is opened, the rotating shaft side moves from when it is in the closed-pole layer and is located at one end above the elongated hole (6), which is closer to the fixed contact (9). The contact opening distance l becomes shorter than when the movable contact 11) rotates and trips at the normal position. Therefore, in a DC circuit, there was a problem that the interrupting performance at a high capacity such as 1000 people was ays.

クタを提供するにある。The present invention has been made in view of the above points, and its purpose is to secure OT by supporting the rotary shaft tube with the long hole of the contactor, and to support the rotary shaft through the long hole of the rotary shaft when opening the contacts. To provide a mid-circuit protector which prevents a fixed contact from moving to one end, thereby increasing contact-pole ms and improving breaking performance.

である。Further, the other end of the movable contactor (1) can be freely engaged with the latch lever +il, and an opening spring (4) can be inserted between this other end and the rotating shaft (3) to rotate the contactor t1). It is elastically biased in the direction of opening the pole. And the frame (

大きく保つ亀のである。This stopper (1) is connected to the rotation axis +31 of the movable contact (l).
It comes into contact with the latch lever (the one end of the latch lever that engages with Il), but in the closed state, it does not come into contact with the movable contact +1 as shown in the figure, and the movable contact He maintains a distance between himself and his child (凰). This gap is approximately equal to the gap a between the rotating shaft side and the upper end of the fixed contact (9) of the elongated hole (-), and is to ensure OT, and due to contact wear, the movable contact (1) is in the direction of the arrow l in the figure.
It is possible to move until there is no space left between fc@ and a. However, when it trips and opens, the elongated hole (@)
The stopper (7) is located closer to the opening spring (4) than K.
The upper surface of the movable contactor (1) is still in contact with the upper surface of the movable contactor (1), which prevents the rotating shaft (3) from moving to the upper end of the elongated hole (6) as shown in FIG. Therefore, the center of rotation of the movable contact +11 does not come close to the fixed contact [1]K, and the contact opening distance l is kept large.

のである。As described above, the present invention is equipped with a stopper that restricts the movement of the movable contact only during its opening operation, and it is possible to increase the contact opening distance without causing any OTK failure of the contact. Therefore, it is possible to improve the breaking performance not only in DC circuits but also in AC circuits, and since it is only necessary to add nine stoppers, it can be applied to general circuit breakers, etc. It is something.
