Technical Field

[0001] This utility model relates to the field of circuit breaker technology, specifically to a circuit breaker assembly. Background Technology

[0002] Currently, there are two types of holding mechanisms for DC fast circuit breakers in China: mechanical holding and electrical holding. Traditionally, mechanical holding mechanisms are used, which are relatively complex, require high-precision machining and assembly processes, and are prone to failure due to mechanical wear after a period of operation. Electrical holding mechanisms, on the other hand, require connecting a magnetic latching relay inside the circuit breaker via wires, increasing the circuit connection steps and increasing the risk of loose connections. Therefore, a circuit breaker assembly is designed to address these issues. Utility Model Content

Figure 1 , 3 As shown, two sets of first copper clips 311 are correspondingly snapped into the partition 712 in the middle. A connector 911 can be assembled between the extension pieces 3114 of the two first copper clips 311 that extend from each other. A connector 211 is further provided on the connector 911, so that the connector 211 can be electrically connected to the two first copper clips 311. The connector 211 is used to connect an external communication DTU data transmission unit.
