Document Type and Number:
WIPO Patent Application WO/2020/083329
Kind Code:
A1
Abstract:
An electrical component, comprising a housing, a contact assembly provided in the housing, and a limiting structure (130) fixed with respect to the housing. The contact assembly comprises: a static contact (150), a moving contact (120), and a contact support portion for providing support for the moving contact (120); the limiting structure (130) may contact or separate from the moving contact (120); once the moving contact (120) is disconnected from the static contact (150), the moving contact (120) is driven by the contact support portion to move linearly a distance and then contact the limiting structure (130), and rotates under the common action of the limiting structure (130) and the contact support portion. Therefore, a clearance between open contacts of an electrical component of a single break structure can be increased, and the arc-extinguishing capability of the electrical component can be improved.
