The invention discloses a tripping structure of an over voltage / current protection breaker. The tripping structure comprises an inductive winding, circles of a coil lead are wound around the inductivewinding, a button contact sheet, i.e., a magnetic iron sheet, is arranged over the winding coil lead, and connected with a connecting rod, the upper end of the connecting rod is provided with a button, a button resetting spring is arranged under the button, and sleeves the connecting rod, the lower of the button resetting spring is arranged on a limiting plate, the lower end of the button resetting spring is connected with a dial rod, the dial rod is provided with an ejector pin, a tripping motion assembly is arranged over the ejector pin, and comprises a tripping arch connecting piece, a tripping arch connecting piece torsion spring and a tripping arch connecting piece resetting torsion spring, the lower of an N-pole moving contact support is connected with the tripping dial rod, and anN pole moving contact is connected to the lower of the tripping dial rod. The tripping structure of the over voltage / current protection breaker is simple in structure, high in intensity, and convenient to install, and the two resetting torsion springs are characterized by long service life and high stability.
Description
technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a tripping structure for an overcurrent protection circuit breaker. Background technique [0002] When the human body gets an electric shock or the leakage current of the power grid exceeds the specified value, the residual current operated circuit breaker can quickly cut off the faulty power supply in a very short time to protect the safety of people and electrical equipment. Therefore, special attention should be paid to the working performance of the circuit breaker. Its working performance is mainly related to the tripping structure in the circuit breaker. The traditional tripping structure adopts a single extension spring reset, which will deform after long-term use, and the circuit breaker will work due to shaking. stability is affected. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present i...
