The circuit breaker with embedded movable conductor J constructed as described above is rotated by a screw 14 rotating on the insulating rod 13. At the time of 13th, 13th, 13th, it can be fixed due to the screwing of the female thread formed on the inner peripheral surface of the hollow portion of the screw rod 14: screw; When Wang Zhi 14 rotates, it is activated. The operating space of the intermediate shaft 11 can be made smaller. Figure 6 shows the state of the connection between the ground and the ground of the circuit breaker. The state of the connection is bad and disconnected. Figure 12 ... When the road is connected The state when the dry thunder m is open, Figure U (c) shows the state when the circuit is grounded. ) As can be seen from the figure, when the insulating rod 13 is rotated, the bolt rod 14 fixed to the end of the insulating rod 13 is not moved in a straight line. The guide core moves to the ground terminal side corresponding to the rotation direction of the insulating rod 13. . On the sub-side, a grounded state and an open state of the circuit can be achieved similarly to the first embodiment. Money-like, angry, and according to this embodiment, the action of the intermediate shaft n can be omitted and simplified.旳 This is more [industrial availability] 315549 14 200522111 According to the present invention, its assembly and adjustment operations are easy, and for a three-point circuit breaker that achieves miniaturization (the connection state, grounding state, and open state of the circuit can be obtained) (Circuit breaker) is very effective.
