Further, two or more of the components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components, without departing from the concepts of the present disclosure.

Referring preferably to fig. 1-2 or 6-7, the circuit breaker includes a housing 1, a handle 2, a stop 3, and an anti-false close button 4. Wherein the housing 1 can be an outer housing 1 of the whole circuit breaker, and the handle 2, the stopper 3, the anti-false closing button 4 and other circuit breaker components can be accommodated in the housing 1, or partially accommodated in the housing 1.

The handle 2 is movably mounted in the housing 1 and can be switched between an open position and a closed position to place the circuit breaker in an open state or a closed state.

The false closing prevention button 4 is movably installed in the housing 1 and can be switched between a locking position and a releasing position.

The stopper 3 is movably mounted in the housing 1 and has a first engagement portion 31 and a second engagement portion 32. Wherein the first engaging portion 31 is engaged with the erroneous closing prevention button 4 regardless of the states of the handle 2, the stopper 3, and the erroneous closing prevention button 4, respectively. The second engagement portion 32 is selectively engageable with the handle 2 to lock or release the handle 2 depending on the situation, as will be described below.

According to the disclosure, the handle 2, the stopper 3 and the false-closing prevention button 4 are installed in a specific manner to achieve the purpose of false-closing prevention. When the anti-false-closing button 4 is in the locking position, the second engaging portion 32 of the stopper 3 engages the handle 2 in the opening position, so that the handle 2 cannot be switched from the opening position to the closing position. When the false closing prevention button 4 is in the release position, the second engagement portion 32 of the stopper 3 is disengaged from the handle 2, so that the handle 2 can be switched between the open position and the closed position. In actual operation, it may be set such that the false closing prevention button 4 is placed in the locking position when the circuit breaker is not correctly installed in the cabinet, and such that the false closing prevention button 4 is placed in the releasing position when the circuit breaker is correctly installed in the cabinet. Thus, when the circuit breaker is correctly installed in the cabinet, since the anti-misclosing button 4 is placed in the release position, the second engagement portion 32 of the stopper 3 is disengaged from the handle 2, and the handle 2 is released by the stopper 3, so that the handle 2 can be switched between the open position and the closed position. When the circuit breaker is not correctly installed in the cabinet, the second engagement portion 32 of the stopper 3 locks the handle 2 at the opening position since the anti-misclosing button 4 is placed at the locking position, so that the handle 2 cannot be switched to the closing position. In this way, the dangerous operation of false closing in case of a correct installation of the circuit breaker is avoided.

According to the present disclosure, the housing 1 has an opening 11, and the anti-false-closing button 4 has a pressing portion 41. The pressing portion 41 is located near the opening 11, when the false closing prevention button 4 is in the locking position, the pressing portion 41 of the false closing prevention button 4 protrudes through the opening 11 of the housing 1, and when the false closing prevention button 4 is in the releasing position, the pressing portion 41 of the false closing prevention button 4 does not protrude from the opening 11.

By such a scheme, the state switching of the false closing prevention button 4 can be realized by pressing the pressing part 41. For the circuit breaker installed to the distribution cabinet, whether the control handle 2 can be switched on or not can be realized according to the installation state of the circuit breaker. Specifically, when the circuit breaker is not correctly installed, the pressing portion 41 of the anti-false-closing button 4 protrudes through the opening 11 of the housing 1, the anti-false-closing button 4 is in the locking position, and the handle 2 is clamped and cannot be closed. Once the circuit breaker is correctly installed, the pressing part 41 of the anti-misoperation closing button 4 is pressed into the shell 1 by the cabinet body, so that the anti-misoperation closing button 4 is in a release position, the handle 2 is not clamped any more, and closing or opening can be performed.

According to the present disclosure, the circuit breaker may further have an elastic member (not shown in the drawings) that biases the mis-closing prevention button 4 toward the opening 11. Thus, when no external force is applied, the false closing prevention button 4 is in the locked position, and the pressing portion 41 thereof protrudes out of the housing 1 through the opening 11 of the housing 1. As an exemplary embodiment, the elastic member may be a spring, one end of which is mounted to the housing 1 and the other end of which is mounted to the anti-false-closing button 4, and is configured to bias the anti-false-closing button 4 toward the opening 11. The present disclosure does not limit the specific structure and installation manner of the elastic member, as long as it makes the false-closing prevention button 4 be in the locking position by default.

Fig. 3 shows an exemplary block diagram of the handle 2 of the circuit breaker.

Wherein the handle 2 may be rotatably mounted to the housing 1. In particular, the handle 2 may comprise a handle base 21 rotatably mounted to the housing 1. The handle base 21 may be disc-shaped.

Wherein the handle 2 may further comprise a handle operating part 22 extending from the handle base part 21. The handle operating part 22 can be manually operated to conveniently switch the handle 2 between the open position and the closed position, thereby switching the circuit breaker to the open state or the closed state. Wherein, the main structure of the handle 2 is positioned in the shell 1, but the handle operating part 22 is positioned outside the shell 1 for convenient operation.

Wherein the handle 2 further comprises a snap-in part 211 on said handle base 21, said snap-in part 211 having a shape matching the second engagement portion 32 of said stop 3. Here, the present disclosure does not limit the specific shape of the engaging portion 211, as long as it is suitable for engaging with the stopper 3.

Fig. 4 shows an exemplary structure diagram of the stopper 3 of the false closing prevention mechanism of the circuit breaker.

Wherein the stopper 3 may have a lengthwise structure, which may be rotatably mounted to the housing 1 at an intermediate position, and the first and

second engagement portions

31 and 32 of the stopper 3 are located at both ends of the stopper 3, respectively.

Wherein the second engagement portion 32 of the stop member 3 is in the shape of a tapered wedge. When the stopper 3 is engaged with the handle 2, the wedge-shaped second engaging portion 32 may be engaged in the engaging portion 211 of the handle 2, respectively.

Wherein the first engaging portion 31 of the stopper 3 is tapered and provided with an arc-shaped profile 311 at a distal end, the arc-shaped profile 311 being engaged in the false closing prevention button 4. In particular, the arcuate profile 311 may be a generally cylindrical structure. In particular, it can engage in a receiving slot 42 of the false-close prevention button 4. The arcuate profile of the arcuate profile 311 is adapted to remain engaged and not damaged when the stopper 3 and the anti-close button are dynamically actuated.

Fig. 5 shows a structure diagram of the false closing prevention button 4 of the false closing prevention mechanism of the circuit breaker.

Wherein the pressing part 41 of the anti-false closing button 4 has an inclined surface so that the position of the anti-false closing button 4 can be switched by the inclined surface.

The provision of this inclined surface helps to smoothly depress the said pressing portion 41 of the anti-false-closing button 4 by the corresponding structure of the cabinet when the circuit breaker is loaded into the cabinet.

Wherein the anti-false-closing button 4 has a lever 43, one end of the lever 43 is rotatably mounted to the housing 1, and the other end is provided with the pressing portion 41 and a receiving groove 42 for receiving the first engaging portion 31 of the stopper 3. In this way, the false closing prevention button 4 has an easy-to-manufacture and compact structure.

The present disclosure also relates to a 5G power distribution cabinet, the 5G power distribution cabinet includes the cabinet body and is located the internal circuit breaker of cabinet, wherein, when the circuit breaker is installed in place in the cabinet body of this 5G power distribution cabinet, the press part 41 of circuit breaker is pressed down by the corresponding part of the cabinet body, and the anti-false-closing button 4 is placed in the release position, and at this moment the second engaging part 32 of stopper 3 with handle 2 declutches, handle 2 is not locked by stopper 3, thereby handle 2 can switch between the break-brake position and the close brake position. The false close prevention button 4 is placed in a locked position by default when the circuit breaker is not properly installed in the cabinet. At this time, the second engaging portion 32 of the stopper 3 engages the handle 2 in the opening position. So that the handle 2 is caught by the stopper 3 and cannot be switched from the open position to the closed position. Thus, it is possible to avoid erroneous closing when the circuit breaker is not correctly mounted.
