Embodiment Construction

[0026] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings, in which the same symbols represent the same parts.

[0027] figure 1 It is a three-dimensional exploded view of the moving contact assembly of an electrical switch of the present invention, which includes a moving contact 20 and a pair of support members 10, and the pair of support members 10 realize the alignment of the moving contact through the mutual connection structure. 20 for solid assembly. Each support 10 has a bottom surface 12 at the bottom and a support body 11 . The bottom surface 12 is disc-shaped, usually disc-shaped for the convenience of manufacture, and the bottom surface 12 has a complementary and radially symmetrical connecting piece 122, which provides conditions for the connection of multiple groups of movin...

Abstract

A movable contact assembly for an electrical switch includes a movable contact and a pair of supports, each support including a bottom face and a support body perpendicular thereto. Each support body includes: a cavity for holding the movable contact disposed symmetrically at each end of a diameter of the bottom face, an inner and outer hook pair extending along the axis of the support body and being disposed symmetrically to the two sides of the diameter; and a projecting tongue and recess pair extending along the axis of the support body and being disposed symmetrically to the two sides of the diameter. The movable contact-holding cavity can hold the movable contact, the two supports can engage with each other in the direction of the axis, and the pair of the supports and the movable contact are assembled together to form the movable contact assembly.

Description

technical field [0001] The invention relates to a moving contact assembly of an electric switch, in particular to a moving contact assembly which can be connected in series. Background technique [0002] In electrical switching devices, moving contact components are usually used to realize the connection and disconnection of circuits through the connection and disconnection between the moving and static contacts. In order to realize the firm installation of the moving contact, there are two commonly used methods at present, one is to connect the two supports through threads, or to use more complicated components. The disadvantages of these two methods are many parts, complex structure, high cost and low efficiency. Contents of the invention [0003] The invention aims to provide a moving contact assembly, which can realize the assembly of the moving contact with fewer parts, and has a simple structure and convenient installation. [0004] Another object of the present in...
