Referring to fig. 1 to 8, the present utility model provides a circuit breaker, which includes an accessory integrated module 1. Referring to fig. 2 to 4, the accessory module 1 includes a mounting member 11, an alarm micro switch 12, and an alarm auxiliary push rod 14. The mounting piece 11 is provided with a mounting position 1111 for mounting the auxiliary micro switch 13, the alarm micro switch 12 is arranged on the mounting piece 11, the alarm auxiliary push rod 14 slidably penetrates through the mounting piece 11, a contact of the alarm micro switch 12 is positioned on a moving path of the alarm auxiliary push rod 14, and the alarm auxiliary push rod 14 is used for triggering the alarm micro switch 12 and the auxiliary micro switch 13. When the alarm auxiliary push rod 14 slides to the contact of the alarm micro switch 12, the contact is pressed down to trigger the contact, and when the alarm auxiliary push rod 14 leaves the contact of the alarm micro switch 12, the contact is reset by itself; thus, the trigger state of the contacts of the alarm microswitch 12 can be controlled by sliding the alarm auxiliary push rod 14.

Because the accessories such as the mounting piece 11, the alarm micro-switch 12, the alarm auxiliary push rod 14 and the like are integrated in the accessory integrated module 1, and the auxiliary micro-switch 13 can be mounted on the mounting position 1111 of the mounting piece 11, the accessory integrated module 1 has higher integration level and more compact structure, thereby leading the circuit breaker to have higher integration level, compact structure and smaller volume.

Referring to fig. 3 and 4, in some embodiments, the accessory integration module further includes an auxiliary micro switch 13 disposed at the mounting location, and a contact of the auxiliary micro switch 13 is located on the moving path of the alarm auxiliary push rod 14. The contact of the auxiliary microswitch 13 is triggered by pressing down the contact when the auxiliary push rod 14 slides to the contact, and is reset by itself when the auxiliary push rod 14 leaves the contact of the auxiliary microswitch 13. Thereby, the trigger state of the contacts of the auxiliary micro switch 13 can be controlled by sliding the warning auxiliary push rod 14.

Referring to fig. 3 and 4, the circuit breaker further includes a shunt trip unit 15, and the shunt trip unit 15 includes a shunt trip 151 and a trip signal micro switch 152. The shunt release 151 is mounted on the mounting member 11 and has a magnetic flux pusher 1511 for effecting release of the circuit breaker. The trip signal micro switch 152 is arranged on one side of the mounting piece 11 far away from the alarm micro switch 12 and is used for transmitting a brake separating signal, and a contact of the trip signal micro switch 152 is positioned on the moving path of the magnetic flux push rod 1511. Thus, the release can be realized by the magnetic flux push rod 1511 of the release 151, and the release signal is transmitted by the release signal microswitch 152.

Specifically, when the circuit breaker is in a closed state or a normal open state, the magnetic flux pushrod 1511 is not in contact with the trip signal micro switch 152; when the circuit breaker is switched from a closed state to an abnormal open state, the magnetic flux push rod 1511 contacts the trip signal micro switch 152, and the trip signal micro switch 152 is triggered by the magnetic flux push rod 1511.

It should be noted that, in some embodiments, because the shunt release 151, the auxiliary micro switch 13, the alarm micro switch 12, the alarm auxiliary push rod 14, the trip signal micro switch 152 and other accessories are all integrated on the accessory integrated module 1, and the trip signal micro switch 152 and the two auxiliary micro switches 13 are all installed on the same side of the mounting piece 11, the integration level of the accessory integrated module 1 is significantly improved, and the structure is very compact, so that the integration level of the circuit breaker is significantly improved, the structure is very compact, and the volume is very small. Moreover, the accessory integration module 1 of the embodiments can be reduced in cost and is also convenient to install compared to scatter purchasing and installing the shunt release 151, the auxiliary micro switch 13, the alarm micro switch 12, the alarm auxiliary push rod 14, and the release signal micro switch 152.

For convenience of the following description, the coordinate systems in fig. 1 and 3 are used when directions are described below, and the coordinate systems in fig. 1 and 3 are aligned.

Specifically, referring to fig. 1, the rotation axis of the moving contact 3 is along the X direction, and the driving member 2 drives the moving contact 3 to rotate clockwise or counterclockwise. The alarm auxiliary push rod 14 is positioned in the +Z direction of the transmission member 2 and is abutted against the transmission member 2. The accessory integrated module 1 comprises an elastic reset piece 16, and the elastic reset piece 16 is arranged on the moving path of the alarm auxiliary push rod 14. When the breaker is opened, the transmission part 2 drives the moving contact 3 to rotate anticlockwise, and in the process, the transmission part 2 jacks up the alarm auxiliary push rod 14, and the elastic reset part 16 is compressed. When the breaker is switched on, the transmission part 2 drives the moving contact 3 to rotate clockwise, and the elastic reset part 16 stretches and pushes the alarm auxiliary push rod 14 to move towards the-Z direction.

It can be understood that an operating mechanism can be arranged in the circuit breaker, the operating mechanism is used for operating the transmission piece 2 to rotate, the operating mechanism comprises a lock catch, a trip button and a traction rod, when the traction rod triggers the lock catch and the trip button to release the lock catch, the circuit breaker trips, and the moving contact and the fixed contact are driven to be separated to realize trip and opening, which is the prior art in the field.

Referring to fig. 6 in combination with fig. 3 to 5, in some embodiments, two auxiliary micro switches 13 are provided, so that the alarm auxiliary push rod 14 can trigger the two auxiliary micro switches 13, the two auxiliary micro switches 13 are distributed in an L shape, and the contacts of the two auxiliary micro switches 13 face the moving path of the alarm auxiliary push rod 14. In other embodiments, the number of the auxiliary micro switches 13 may be more than two, the auxiliary micro switches 13 enclose an avoidance space for the auxiliary alarm push rod 14 to pass through, and the contacts of the auxiliary micro switches 13 face the avoidance space, so that the auxiliary alarm push rod 14 presses down the contacts of the auxiliary micro switches 13 when passing through the avoidance space.

In some embodiments, along the direction of the alert micro-switch 12 toward the mounting location 1111 (i.e., the +z direction), there is a first position, a second position, and a third position in sequence on the active path of the alert assist push rod 14. When the breaker is switched on, the alarm auxiliary push rod 14 is positioned at a first position, and at the moment, the alarm auxiliary push rod 14 is separated from the alarm micro switch 12 and the auxiliary micro switch 13, and the micro switches do not transmit signals; when the breaker is normally opened, the alarm auxiliary push rod 14 is positioned at the second position, and at the moment, the alarm auxiliary push rod 14 presses a contact of the auxiliary micro switch 13 and is separated from the alarm micro switch 12, the auxiliary micro switch 13 transmits a signal, and the alarm micro switch 12 does not transmit a signal; when the circuit breaker is abnormally opened, the alarm auxiliary push rod 14 is positioned at the third position, at the moment, the alarm auxiliary micro switch 13 presses the contact of the alarm micro switch 12 and the contact of the auxiliary micro switch 13, the alarm micro switch 12 and the auxiliary micro switch 13 both transmit signals, and the circuit breaker alarms. Thus, the first position, the second position and the third position on the moving path of the alarm assisting push rod 14 correspond to three working states of the circuit breaker respectively: the switching-on state, the normal switching-off state and the abnormal switching-off state, so that the alarm micro switch 12 and the auxiliary micro switch 13 are respectively in different trigger states to prompt a user of the working state of the circuit breaker. The normal brake release means that the breaker is released by manually rotating an operating rod of the breaker, and the abnormal brake release means that the traction rod is triggered by a magnetic flux push rod 1511 to release the snap fit, so that the breaker is tripped, and the breaker is released.

Referring to fig. 1, as mentioned above, when the breaker is opened, the driving member 2 drives the moving contact 3 to rotate counterclockwise, and in this process, the driving member 2 jacks up the auxiliary alarm push rod 14, and the elastic reset member 16 is compressed. It will be appreciated that the angle by which the movable contact 3 rotates during normal opening is smaller than during abnormal opening.

Referring to fig. 3 and 6, when the alert assist push rod 14 is in the first position, the first ramp 143 faces the contacts of the alert micro switch 12 and the second ramp 144 faces the contacts of the assist micro switch 13. In the process of pressing the microswitches by the alarm auxiliary push rod 14, the contacts of the microswitches are contacted with the inclined planes, and the inclined planes gradually press down the contacts of the microswitches along with the movement of the alarm auxiliary push rod 14 towards the +Z direction, so that the microswitches are triggered.

Referring to fig. 7 in combination with fig. 6, for the embodiment in which the auxiliary micro switch 13 is provided with two, the alarm auxiliary push rod 14 may further be provided with a third inclined surface 145, and when the alarm auxiliary push rod 14 is in the first position, the second inclined surface 144 and the third inclined surface 145 respectively face the contacts of one auxiliary micro switch 13.

When the alarm assisting push rod 14 is at the first position, the first abutting part 141 abuts against the stop part 1121; when the warning support push rod 14 is in the third position, the second contact portion 142 contacts the mounting plate 111. Thereby, the stroke of the auxiliary alarm push rod 14 can be limited, ensuring that the auxiliary alarm push rod 14 is only moved between the first position and the third position.

Referring to fig. 3 and 4, the elastic restoring member 16 is disposed between the mounting member 11 and the second abutment 142, so that the alarm assisting push rod 14 can be returned to the first position by the elastic restoring member 16. In order to ensure that the alarm assisting push rod 14 can reach the third position, the elastic restoring member 16 is provided with a hollow structure, and the elastic restoring member 16 is provided with a through hole along the Z direction for the second abutting portion 142 of the alarm assisting push rod 14 to pass through. When the alarm assisting push rod 14 is at the first position, the elastic reset piece 16 is released downwards, and the first abutting part 141 abuts against the stop part 1121; when the warning assisting push rod 14 is in the third position, the elastic restoring member 16 is compressed upward, and the second abutting portion 142 abuts against the mounting plate 111.

Thus, the cover 112 and the attachment 11 protect the shunt release 151, and the possibility of failure of the shunt release 151 due to external factors can be reduced.

Preferably, referring to fig. 2, the alarm micro switch 12 is disposed on a side of the cover 112 facing away from the accommodating space 1122. Thus, shunt release 151 is spaced from alert micro-switch 12, which is advantageous in avoiding magnetic flux pushrod 1511 and alert auxiliary pushrod 14 interfering with each other.

Referring to fig. 4, the cover 112 is provided with a avoiding groove 1123, the magnetic flux push rod 1511 passes through the avoiding groove 1123, and the groove wall of the avoiding groove 1123 is in profiling fit with the part of the magnetic flux push rod 1511 passing through the avoiding groove 1123.

Thus, the trip signal micro switch 152 and the auxiliary micro switch 13 can be fixed and protected.

In some embodiments, the cover 17 and the mounting member 11 are detachably connected together by a screw connection, a clamping connection, or the like. Three clamping grooves are formed in one side, facing the mounting piece 11, of the cover body 17, and the alarm auxiliary push rod 14 and the two auxiliary micro switches 13 are respectively clamped in one clamping groove. Thus, when the user only needs one auxiliary micro switch 13, the cover 17 can be detached, and any auxiliary micro switch 13 can be detached from the cover 17; when the user does not need the auxiliary micro-switches 13, the cover 17 can be detached, and both the auxiliary micro-switches 13 can be detached from the cover 17. Of course, in other embodiments, the three clamping grooves may be formed on a side of the mounting member 11 facing the cover 17, and the cover 17 and the mounting member 11 may be connected together by other detachable connection manners.

Referring to fig. 2 to 4, the accessory integrated module 1 includes a communication terminal 18, the communication terminal 18 being used to transmit signals to implement a remote breaking circuit breaker. In order to reduce the volume of the accessory integrated module 1, the accessory integrated module 1 is also mounted on the side of the mounting member 11 remote from the alarm micro switch 12.
