The embodiment of the application also provides a residual current circuit breaker, and the schematic cross-sectional view of the residual current circuit breaker is shown in fig. 6.

Referring to fig. 6, the residual current circuit breaker includes a case 3, and at least one electric leakage indicating structure according to an embodiment of the present application mounted in the case 3.

The shell 3 has a partition 31, and a fourth protrusion 311 and a rotating shaft 312 are provided on the surface of the partition 31; the cylinder 11 is sleeved on the rotating shaft 312 and can rotate around the rotating shaft 312; the first end 111 is the end of the cylinder 11 close to the partition plate 31; the second arm portion 23 abuts against the fourth protrusion 311, and the fourth protrusion 311 can give a steering force to the push rod 1 after the leakage indicating structure is assembled. For example, as shown in fig. 6, the fourth protrusion 311 may give the push rod 1 a clockwise rotation force.

Through having adopted electric leakage indication structure for assembly process at this electric leakage circuit breaker is simple convenient.

With continued reference to fig. 6, the surface of the fourth protrusion 311 away from the partition plate 31 is inclined from the high side to the low side, that is, the side of the fourth protrusion 311 away from the partition plate 31 is an inclined surface, and the wall surface of the fourth protrusion 311 adjacent to the low side of the surface abuts against the second arm portion 23.

When the leakage indicating structure is mounted on the spacer 21, since the side of the fourth projection 311 remote from the spacer 31 is a slope, it is convenient to provide a guide for the second arm portion 23 so that the second arm portion 23 can be scratched by the slope to the wall surface adjacent to the lower side of the surface.

For the housing 3, reference is made to fig. 11, which is a schematic illustration of the structure of a partition 31. Referring to fig. 11, the plate surface of the partition plate 31 further has a pressure receiving plate 315, and after the indicating assembly 5 is installed in the housing 3, one end of the second elastic member 53 abuts against the pressure receiving plate 315, and the other end abuts against the cavity wall of the accommodating cavity 521 on the side away from the extension arm 51; the housing 3 has a through hole 32, and when the line leaks electricity, the end of the fixing portion 52 away from the extension arm 51 can extend out of the housing 3 through the through hole 32.

Fig. 8 is a schematic structural diagram of the electrical leakage circuit breaker according to the embodiment of the present application when an electrical leakage occurs in a circuit. Referring to fig. 8, in a possible implementation manner, the residual current circuit breaker further includes an open-side latch 4, and the first arm 16 abuts against a column 41 on the open-side latch 4 when a current leakage occurs in the circuit.

When the line leaks, the pillar 41 contacts both the first sub-arm 161 and the second sub-arm 162 as shown in fig. 8.

Since the open-side lock 4 is located on the side of the plate surface of the partition plate 31 facing away from the fourth protrusion 311, in order to facilitate the movement of the cylinder 41, referring to fig. 11, the cylinder 41 can slide through the sliding channel 313 on the partition plate 31.

Alternatively, the sliding channel 313 may be an arc-shaped channel.

Fig. 12 is a front view of an electrical leakage breaker according to an embodiment of the present application. Referring to fig. 12, the residual current circuit breaker also has a handle 7. The handle 7 may be used, among other things, to indicate line overload, short circuit or leakage. When the handle 7 is tripped to the opening position and the indicating component 5 is not bounced, the overload or short-circuit fault is indicated; when the indicating component 5 is bounced up and the handle 7 is also tripped to the opening position, the leakage fault is indicated.

When the leakage indicating structure and the indicating assembly 5 in the leakage circuit breaker are assembled, the second elastic member 51 may be first placed in the accommodating cavity 521 to form the indicating assembly 5, the indicating assembly 5 is then installed into the housing 3 from the through hole 32, and the extension arm 51 is ensured to enter the guide groove of the guide member 314, and one end of the second elastic member 53 abuts against the pressure receiving plate 315; then, the sleeving part 21 of the first elastic element 2 passes through the limiting channel 13 and is sleeved on the cylinder 11, and the first arm part 22 abuts against the first protrusion 121, so that the cylinder 11 is sleeved on the rotating shaft 312 after the first elastic element 2 and the push rod 1 form a leakage indicating structure; finally, the second arm 17 is abutted against the extension arm 51, and the second arm 23 is pressed to abut against the fourth projection 311.

Based on above-mentioned structure, the theory of operation of the electric leakage circuit breaker that this application embodiment provided does:

when the circuit normally runs, referring to fig. 7, the extension arm 51 of the indication component 5 is limited in the guide groove of the guide part 314 on the partition board 31 and abuts against the second arm 17 of the push rod 1, and the fourth protrusion 311 on the partition board 3 always gives a clockwise rotation force to the push rod 1 through the first elastic part 2, so that the second arm 17 and the extension arm 51 are locked and buckled, and the indication component 5 is always limited in the casing 3.

When the circuit leaks electricity, referring to fig. 8, after the mutual inductor in the leakage circuit breaker detects the leakage, the circuit board judges whether the current value of the leakage reaches the threshold value, and after the threshold value is confirmed to be reached, the circuit board sends a tripping signal to the tripper 6, so that the ejector rod 61 on the tripper 6 acts to push one side of the first arm 16 to move in the direction away from the tripper 6, and further the push rod 1 is pushed to rotate anticlockwise. At this time, on one hand, the other side of the first arm 16 pushes the cylinder 41 on the idle side lock catch 4 to move, so that the idle side lock catch 4 rotates anticlockwise, the circuit is cut off, and the handle 7 returns to the brake separating position; on the other hand, since the second arm 17 is far away from the extension arm 51, the second arm 17 and the extension arm 51 are buckled, and under the elastic action of the second elastic member 53 inside the indication assembly 5, the end of the fixing portion 52 far away from the extension arm 51 pops out of the through hole 32, that is, the leakage indication button of the leakage circuit breaker can be observed by a person from the outside to pop up.

It will be appreciated that when the line fault is cleared, the handle 7 can be returned to the closed position by first snapping the retainer 52 into the housing 3.

The above description is only exemplary of the present application and should not be taken as limiting, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
