At this time, the self-movable contact 1B) is urged by the tensile force of the tension spring and is separated to a position where it abuts the opening edge Vc of the bottom opening IB (18a) of the movable frame H. The buckle (4) is also biased by the tensile force of the bow 1 tension spring, and is stopped at the position where the groove (4b) is engaged with the protrusion. Also, one bit of the torsion spring is the handle (4
) is suppressed by the outer w4 surface of the torsion spring −O
The other end is stored at the point t1 of the contact piece (6) of the latch plate (b), and the empty space F! Intervening within s. 6th
The figure shows a sectional view taken along the line X-X in Figure 5, and if you look at the figure, you can see that the center IIC19m of the rotating shaft - and the pin 4 of the movable arm are being pulled together by the tension h-. Figure 1 shows the state when the circuit breaker is on, and in this state ν is the movable contact (6).
is energized by the tensile force of ha, and the town To! lII
: The handle (4), which is stopped at the position where the L garden is pressed against the fixed contact, is also biased by the tensile force of the tension spring, and the operating part of the handle (4) is pressed against the casing J. )(L)(ms) and stops at the position where it is in contact with h. In this way, the direction in which the movable wJ contactor (6) ν and the operation part of the handle (4) are biased is due to the tension spring. WA@
The axis as OrjiA is designed to reverse at the point where it crosses the center of rotation P. However, in the ON state of the circuit breaker, one end of the K torsion spring t4'co as shown in FIG. The other end s of the torsion spring t4I is no longer pressed against the outer peripheral surface of the hashidle (4).
The pressure contact force is weaker than in the state when #i is OFF, and a desired force is applied to the contact piece. Therefore, if the side of the bimetal is deformed by the over-ia flow and presses the abutting one-sided contact, or if the three-way plate 03 is magnetized by the short-circuit current flowing through the bimetal (1@) and attracts the magnetic attraction piece I, The latch W@ is designed to rotate around the shaft support pin, and this causes the locking step part (44 and the locking part 14 to become uncoupled), causing the splice to extend. , the movable frame + 11 is adapted to rotate about the rotation center P of the rotation axis -. Since the movable frame (1) is pressed by the spring and rotates, the movable contact (6) is forced by the opening edge of the bottom opening (18a) of the movable frame (+). It is designed so that it is driven in the contact opening direction.

When the movable contact 1B) is opened by a predetermined distance, it is further driven in the direction of opening the button contact by the tensile force of the tension arm, and finally the movable arm aη comes into contact with the shaft support bis GIK and is movable. The arm (17+) stops, and the hashidle (4) moves into the groove (
4b) is adapted to stop at a position where it is engaged with the protruding part @ of the movable frame On. At this time, since the movable frame O is tilted, the operation section of the hash door (4) stops approximately at the center between the OFF position and the OFF' position, indicating that a trip operation has been performed. When such a tripping operation is performed, the handle (4) as shown in FIG.
Once returned to the off position, the locking step part (goods) and the locking part (c)
If Hasidor (4) is stopped in the Oshi position of Confucianism, it will not be possible to perform Seven unless the union is restored. Furthermore, as is clear from a comparison of Fig. 5 and Fig. 7, the opening of the bottom opening (18 m) of the movable frame 1 (IIj) is formed to be longer than the opening/closing stroke of the movable contact (6). Therefore, when tripping is not performed as in manual opening/closing operation, the VcFi movable contact (6) is activated by a spring or a contact breaking mechanism such as the movable frame OT4 or M5. In this embodiment, one end of the screw spring is separated from the hash door (4), so that when the latch plate 6η is turned off, the abutment part of the latch plate 6η is strongly Since it is pressed, it is possible to reduce the possibility that the locking step portion 144) and the locking portion (49) will become disengaged due to vibration when manually opening and closing the hashidor.
