本発明は電子式配線用しゃ断器に係り、特に、引き外し
機構の自動リセットに好適なリセット機構に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an electronic circuit breaker, and particularly to a reset mechanism suitable for automatically resetting a tripping mechanism.

位置からリセット位置に戻してやらなくてはならない。Generally, the magnetic tripping device used in this type of circuit breaker performs the tripping operation by a weak signal from the overcurrent detection unit, so the magnetic flux of the permanent magnet is used to release the d.
The movable armature is held in the reset position by overcoming the force of the spring, and the magnetic flux generated by the tripping coil cancels the magnetic flux of the permanent magnet to release the movable armature, which is then held by the force of the spring. This device moves the breaker to the tripping position and transmits the movement to the exception member inside the breaker, and unlike the normally used thermal electromagnetic exception device, it is used to make the exception device operable again. In this case, the movable armature must be returned from the exception position to the reset position by an external force.

載されている。Conventionally, the mechanism for resetting the magnetic string removal device is as follows:
As an exception, there is a device in which the movable armature of the magnetic line removal device is moved to the reset position via an actuator in contact with one end of the handle by the reset operation of the breaker operating handle after operation; It is fully described in Publication No. 18861 and Japanese Patent Publication No. 5A-SSOS. There is a device in which the movement of the breaker contact arm to the open position due to the switching operation is transmitted via an actuator to the movable armature of the magnetic line removal device to move it to the reset position. It is described in No. 31JA2A.

性に乏しい。However, with the method of resetting using the handle, the device must work not only in the ON state but also in the OFF state due to the magnetic pull-off, so the slight displacement of the handle between the OFF state and the reset state must be controlled by tJ. The magnetic trip device must be reset. In addition, since the actuator cannot be released after the reset is completed, the actuator interferes with the movement of the movable armature.Also, the method of resetting via the actuator by movement of the contact arm requires the support member of the contact opening/closing mechanism part of the contact arm, the magnetic tripping device, Latch #16 structure is omitted.
Since each of these parts is foamed separately and consists of many parts, precision of the component parts and precision of adjustment work are required. Therefore, when the circuit breaker is opened, closed, or disconnected, the high-speed mechanical operation and overstroke cause deformation of the component parts, resulting in malfunction. In the case of the above-mentioned tokuizawa, it is also unreliable because it uses a slight displacement of an excessive force.

態を経て再び第6図(Alの状態に戻る。At this time, since the pressing force of the hook 5 is no longer applied to the abutting portion 11a of the lever 11, the lever 11 becomes rotatable in the direction of the noon mark F as shown in the 61st FI (Dl), and the restoring force of the compression spring 15 As a result, the reset lever 13 is urged in the direction of the arrow H, and moves to a position where it contacts the stopper 61 while pushing the half plate 7IO with the loose fitting portion 13b.As a result, the movable armature 10 is pushed back to the initial position. , the magnetic flux of the permanent magnet A3 attaches it to the support frame A1 again and returns to the initial state, and the magnetic flux is removed and the device wt9 is reset.After this state, if the circuit breaker is tripped, as shown in Fig. 6. The handle 2 remains at the trip position as shown in Figure 4.The circuit breaker can be reset by returning the handle 2 to the reset position as shown in Figure 4. ) as shown in FIG.
Touch and press the ia diagonally. Since the U-shaped notch 4c of the trip fitting A loosely fits into the support shaft 32, the trip fitting A slides in the direction of arrow C due to the pressing force of the tip 3a of the hook 6, and the hook 5 further moves in the direction of the arrow C. #Engagement part 4 in H direction
Since the reset mechanism is relatched to the point a, the reset mechanism returns to the state shown in FIG. 6 (El) and then back to the state shown in FIG. 6 (Al).

図に示すようにねじつばね50としてもよい。According to this embodiment, during the tripping operation of the magnetic lamp tripping device, the reset lever 13 is on standby at a position greater than the stroke of the bin 10a, and the driving force of the bin 10a is small because it does not hinder the movement of the bin 10a. The device can be made smaller and lighter. In addition, the lever 11 is pressed by the lever 11 during tracking and resetting, but when it is tripped, the suppression is released, and the resulting rotational movement of the lever is used to drive the reset mechanism, so a constant reset force is applied. can get. Since excessive force is not applied to each twisted part, deformation of the parts is less likely to occur, resulting in a long service life. In other embodiments, as shown in FIG. 8, a return spring 15' may be provided on the bottle 10a and the guide may be omitted, since the stroke of the return spring 15' may be small.
There is a margin for the stress of the return spring 15' at the time of resetting. Further, the reset lever biasing means may be a tension spring 15 as shown in FIG. Furthermore, the urging means is
A screw spring 50 may be used as shown in the figure.

According to this, the movement of the reset lever 53 is minimized, and the device is made smaller and can be stored in a narrow space. In addition,
If configured as shown in FIG. 12) (B), the guide 63 may be provided on one side. In this case, the tension spring 14 receives a bending force when passing through the guide plate A2, but since the spring material has elasticity, it does not form a pot shape. In a further different embodiment, as shown in FIGS. 13(A) and 13(B), the reset ports 54 and 5a/ may be provided with an elastic body. According to this, the mechanical part can be simplified, the number of assembly steps can be reduced, and the device can be made smaller and smaller. The elastic body may be a spring or a soft synthetic resin plate. In this case, the mounting portion of the tension spring 14 may be provided with reinforcement (not shown) if necessary.
