Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to a circuit breaker which is easy to disassemble and assemble. Background Art

[0002] Circuit breakers are often used to automatically cut off circuits when a distribution system experiences severe overload, ground short circuit, or undervoltage faults. Traditional circuit breakers are mostly installed in an integrated housing structure, requiring technicians to use bolts or screws to fix the circuit breaker as a whole in the installation position. Circuit breakers installed in this way are difficult to disassemble and assemble, and cannot be quickly disassembled and assembled or conveniently repaired.

[0003] In response to the above problem, a Chinese patent announcement with announcement number CN217468311U discloses a circuit breaker that is easy to disassemble and assemble. The technical key points are: a first clamping seat and a second clamping seat are arranged at both ends of the mounting seat to form a clamping position, and the circuit breaker body is adapted to be clamped on the clamping position and locked by a locking seat. Since the locking seat locks the circuit breaker body in normal state (or under reset action), it can be away from and loosened by an external force.

[0004] In actual operation, it is found that the above scheme still has at least the following defects: most circuit breakers have slightly different uses, resulting in inconsistent widths. After replacing a damaged circuit breaker, it is inconvenient to adjust the spacing of the existing circuit breakers, which affects the installation efficiency and aesthetics. Therefore, we propose a circuit breaker that is easy to disassemble and assemble to solve the above problems. Utility Model Content
