Abstract
The utility model discloses a safety breaker. The breaker comprises a moving leaf, a fixed leaf, a rotating shaft, a conductor one, a conductor two, a moving connection sheet, and a fixed connection sheet. The moving leaf is movably arranged on the fixed leaf via the rotating shaft, and the moving connection sheet is fixedly arranged on the surface of the rotating shaft. The fixed connection sheet in an arc shape is arranged on the periphery of the rotating shaft, and includes a connection sheet one, a connection sheet two, and an insulation sheet disposed between the connection sheet one and the connection sheet two. Together the connection sheet one, the connection sheet two and the insulation sheet form an arc with an inner surface radius not greater than an outer surface radius of the moving connection sheet. The connection sheet one is led out via the conductor one, and the connection sheet two is led out via the conductor two. The breaker can automatically cut off a circuit when an electrical equipment door is opened, so that an operator is prevented from electric shock, and the safety of operation is ensured.
