[0056] Referring to Figures 1 to 6 The embodiment provides a plug-in circuit breaker device, which comprises a plug-in base 100, an indication assembly 300 and a circuit breaker 400.

[0057] Specifically, the plug-in base 100 is provided with a terminal seat 200; the indication assembly 300 comprises a first elastic member 310 and an indication member 320, the first elastic member 310 is arranged between the plug-in base 100 and the indication member 320, the indication member 320 is slidingly arranged in the plug-in base 100, and the indication member 320 comprises an indication part 321; the circuit breaker 400 comprises a shell 410 and a conductive column 420 arranged on the shell 410.

[0058] When the circuit breaker 400 is connected with the plug-in base 100, the conductive column 420 is connected in the terminal seat 200 and abuts against the indication member 320, and the indication part 321 is located in the plug-in base 100; when the circuit breaker 400 is separated from the plug-in base 100, the indication part 321 protrudes out of the plug-in base 100 under the elastic action of the first elastic member 310.

The indicating member 320 is pushed by the conductive column 420, and the indicating part 321 is retracted from outside the plug-in base 100 to inside the plug-in base 100, so as to indicate that the conductive column 420 is inserted into the terminal seat 200, which facilitates the personnel to identify and effectively prevents the line equipment from being damaged due to the high temperature rise of the circuit breaker 400. In addition, when the circuit breaker 400 is pulled out of the plug-in base 100, the indicating member 320 is reset under the elastic action of the first elastic member 310, so that the indicating part 321 protrudes outside the plug-in base 100, which facilitates the indication of the insertion of the conductive column 420.

[0060] Exemplarily, the conductive column 420 can be fixed to the shell 410 by a screwing member.

[0061] In the embodiment, referring to Figures 1 to 3 , the indicating member 320 includes a first column 322 and a second column 323 which are arranged in parallel with each other.

In the embodiment, the conductive column 420 pushes the second column 323, so that the indicating member 320 slides into the plug-in base 100, and the indicating part 321 on the first column 322 is retracted into the plug-in base 100, which is stable and reliable. The arrangement of the first column 322 and the second column 323 can make the structure of the indicating member 320 compact, and make room for the terminal seat 200, so as to avoid the position interference between the indicating member 320 and the terminal seat 200.

[0062] Specifically, the plug-in base 100 is provided with a room hole 121 through which the indicating part 321 is arranged.

[0077] Exemplarily, the first elastic piece 310 can be a spring.

[0078] In the embodiment, referring to Figure 1 , Figure 7 and Figure 10As shown, the conductive column 420 has a plug-in part, the circuit breaker 400 further comprises a signal module 500 and an electromagnetic release (not shown) arranged on the shell 410, the signal module 500 is in communication connection with the electromagnetic release, the signal module 500 comprises a trigger 510 which protrudes out of the shell 410; wherein the circuit breaker 400 has a disconnection position, a breaking position and a conduction position in sequence when being plugged into the plug-in base 100; at the disconnection position, the plug-in part is disconnected from the terminal seat 200, and the trigger 510 is disconnected from the plug-in base 100; at the breaking position, the plug-in part is partially plugged into the terminal seat 200, and the trigger 510 is disconnected from the plug-in base 100; at the conduction position, the plug-in part is plugged into the terminal seat 200, and the trigger 510 abuts against the plug-in base 100. Wherein the disconnection of the trigger 510 from the plug-in base 100 can trigger the signal module 500 to send a tripping signal to the electromagnetic release. It can be understood that the circuit breaker 400 is at the conduction position, i.e. the circuit breaker 400 is plugged into the plug-in base 100 in place. In this embodiment, during the process of pulling the circuit breaker 400 out of the plug-in base 100, when the circuit breaker 400 is pulled to the breaking position, the trigger 510 is disconnected from the plug-in base 100 and triggers the signal module 500 to send a tripping signal to the electromagnetic release, for example, when the circuit breaker 400 is in a closed state, the circuit breaker 400 will trip through the electromagnetic release to ensure that the circuit breaker 400 is disconnected, i.e. under the condition that the circuit breaker 400 is disconnected, the plug-in part can be disconnected from the terminal seat 200, effectively preventing misoperation caused by carelessness and ensuring personal safety.

[0079] Exemplarily, the shell 410 is provided with a receiving groove 411 for accommodating the signal module 500, so as to facilitate the positioning and assembly of the signal module 500 and effectively ensure the compact structure of the circuit breaker 400.

The trigger member 510 is separated from the plug-in base 100 to trigger the micro switch 530 to send a trip signal to the electromagnetic release. It can be understood that the trigger member 510 protrudes from the module housing 520. In this embodiment, during the process of pulling the circuit breaker 400 out of the plug-in base 100, the trigger member 510 slides out of the module housing 520 under the action of the second elastic member 540, so that the trigger member 510 always abuts against the plug-in base 100 before the circuit breaker 400 is pulled to the breaking position, and until the circuit breaker 400 is pulled to the breaking position, the trigger member 510 is separated from the plug-in base 100 and triggers the micro switch 530, which is stable and reliable, so as to ensure that the plug-in part can be separated from the terminal seat 200 only after the circuit breaker 400 is disconnected.

[0081] Exemplarily, the module housing 520 is provided with a connecting lug 521, which can be fixed on the shell 410 by a screwing member, facilitating the assembly and fixation of the module housing 520.

[0082] Specifically, the micro switch 530 comprises a button 531, and the trigger member 510 is provided with a clearance groove 511. When the circuit breaker 400 is in the separation position and the breaking position, the button 531 is located in the clearance groove 511. When the circuit breaker 400 is in the on position, the button 531 is located outside the clearance groove 511 and abuts against the trigger member 510, so as to press the button 531. When the button 531 is released from the pressing of the trigger member 510, the micro switch 530 is triggered, facilitating the triggering of the micro switch 530.

[0083] In a feasible embodiment, the plug-in base 100 is provided with a protruding part 114, and the trigger member 510 can abut against the protruding part 114. Specifically, the protruding part 114 is arranged on the seat body 110. In this embodiment, by arranging the protruding part 114, the activity range of the trigger member 510 can be reduced, that is, after the trigger member 510 is separated from the plug-in base 100, the plug-in part can be separated from the terminal seat 200 more easily during the process of pulling the circuit breaker 400 out of the plug-in base 100.
