Embodiment approach

[0034] Furthermore, please also refer to image 3 and Figure 4 , as a specific embodiment of the neutral pole mechanism provided by the present invention, the linkage assembly 1 includes a contact support 11 for fixed connection with the linkage shaft 3 of the phase line pole tripping mechanism and a The base 12 of the contact support 11 , the linkage shaft 3 passes through the base 12 and is connected to the contact support 11 . Specifically, the base 12 is used to support the contact support 11, and the contact support 11 is used to connect the movable contact 21 and the linkage shaft 3, and transmit the movement of the linkage shaft 3 to the contact support 11, so that The contact support member 11 can drive the movable contact 21 to move towards the static contact 22 .

[0035] Further, see Figure 4, as a specific embodiment of the neutral pole mechanism provided by the present invention, the base 12 is provided with a long hole 121 for the movement of the linkage sha...

Abstract

The invention provides a neutral pole mechanism and a residual current circuit breaker. The neutral pole mechanism comprises a linkage assembly used for being connected with a phase line pole trippingmechanism and a contact assembly driven by the linkage assembly to move, wherein the contact assembly comprises a moving contact, a static contact and an arc striking plate, the moving contact is driven by the linkage assembly to rotate and drive the moving contact to get close to the static contact, the static contact is fixed to the arc striking plate, and the arc striking plate extends towardsthe side away from the linkage assembly. The neutral pole mechanism is advantaged in that adjacent phase line pole tripping mechanisms are connected with the neutral pole mechanism, the contact assembly is driven by the linkage assembly to link with the phase line pole tripping mechanism, the arc striking plate is directly arranged on one side of the static contact, an electric arc is led to theside away from the linkage assembly, the arc extinguishing effect can be achieved through cooperation of the moving contact and the static contact, the electric arc can be led out quickly, and therebythe electric arc can be extinguished.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to a neutral pole mechanism and a residual current circuit breaker. Background technique [0002] With the increasing number of electrical equipment used by household users, the application of residual current circuit breakers is also increasing. At present, residual current circuit breakers are generally implemented in the way of neutral pole direct connection. Using the breakable structure of residual current circuit breakers, it can When the equipment is powered off, it also provides electrical isolation protection for the neutral pole. In the prior art, a circuit breaker with the same phase line pole is generally used as the protection of the neutral pole, that is, an additional residual current protection module is added. However, after the additional residual current protection module is added, the volume of the entire product occupies a large area. ...
