other Embodiment approach

[0038] In other embodiments, the rotating member 7 can also be coaxially and fixedly connected with the transmission member 9, and the fixed connection can be selected from other anti-rotation connection methods such as clamping connection to synchronize with the transmission member 9 turn.

[0039] The rotating member 7 is provided with a driving portion 72 for driving the linkage member 3 . The driving portion 72 is a protruding structure extending radially along the pivoting portion.

[0040] As a preferred embodiment, the pivoting part is also provided with a radially extending limiting projection 73, and the housing 1 is provided with a corresponding limiting boss, such as figure 1 As shown, the cooperation of the limiting protrusion 73 and the limiting boss can limit the rotation range of the pivoting part in the clockwise direction.

[0041] Under the action of the rotating member 7, the linkage member 3 can rotate around the third rotation axis. The linkage 3 is syn...

Abstract

The invention provides a circuit breaker. The circuit breaker comprises a shell, a contact system, a transmission system, a tripping system, a driving motor and an operating handle, wherein the transmission system comprises a driving piece, a transmission piece, a rotating piece and a linkage piece; an elastic piece is arranged between the transmission piece and the shell; the stripping system comprises a stripping shaft; and a trigger part for pressing the tripping shaft is arranged on the transmission piece or the rotating piece. When a user is in arrearage, the driving motor drives the transmission piece to overcome the elastic force of the elastic piece to rotate to a set angle, the stripping shaft is pressed, and the contact system is switched off; after the user pays the fee, the driving motor continues to rotate, the stripping shaft is not pressed any longer, the transmission piece is detachably matched with the driving piece, the transmission piece turns round under the elastic force effect of the elastic piece, and the linkage piece is driven through the rotating piece, so that the contact system is switched on. Therefore, before the user continues to pay the electric charge, the user cannot get the electricity automatically due to the fact that the stripping system is at a trigger state and the operating handle can automatically reset to a switch-off position even if the operating handle is artificially pulled to be switched on.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances. Specifically, a circuit breaker. Background technique [0002] Miniature circuit breakers, also known as miniature circuit breakers, are suitable for overload and short circuit protection of AC 50-60Hz rated voltage 230-400V, rated current up to 63A, and can also be used for infrequent operation of the line under normal conditions. It is mainly used in various places such as industry, commerce, high-rise buildings and residential buildings. [0003] According to the requirements of the State Grid, in the line of the prepaid meter, the lower end of the smart meter needs to be installed with a smart circuit breaker. When the user's meter is in arrears, the smart circuit breaker can automatically disconnect the line. After the user renews the fee, the smart circuit breaker will automatically reclose, close the circuit, and supply power. [0004] In the prior art, the Chinese Paten...
