Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] The main structure of the moving contact device provided by the present invention includes a moving contact body 1 , a non-ferrous metal flexible wire 2 and a terminal 3 . Such as figure 1 As shown, the moving contact body 1 is a sheet-shaped conductive material, and its front end is connected to the non-ferrous metal soft wire 2 by welding.

[0025] The material used for the moving contact body is copper, and other materials such as iron can also be used. When other materials are used, a conductive contact with a resistivity lower than that of the movable contact body needs to be connected to the movable contact body, and the non-ferrous metal flexible wire 2 is connected to the conductive contact by riveting or welding. The other end of the non-ferrous metal flexible wire 2 is connected to the terminal 3, and may also be connected to the rear end of the mo...

Abstract

The invention provides a moving contact device of a relay, which has a simple structure, a low cost and a high current carrying capacity, is favorable for splitting heavy currents, and has large open-distance and high working reliability. The moving contact device comprises a moving contact body, wherein the moving contact body is of a strip sheet-shaped structure, a nonferrous metal flexible wire is connected at the front end of the moving contact body, a pivot point is arranged between the middle part and the rear end of the moving contact body, and a strained structure is arranged in front of or at the back of the moving contact body and driven by an external force to rotate the moving contact body around the pivot point.

Description

technical field [0001] The invention relates to a moving contact device, in particular to a moving contact device for a relay, and belongs to the electric field. technical background [0002] The relay plays the role of automatically connecting and disconnecting the circuit. At present, the moving contact device of the single break point relay generally includes the moving contact terminal, the moving reed and the moving contact, wherein the moving reed and the moving contact are riveted or welded on the Together, the moving contact terminal and the moving reed are riveted or welded at the end of the moving contact terminal. This connection point becomes the fulcrum of the moving reed, and the moving reed rotates around this fulcrum when it is stressed to realize the connection and disconnection of the circuit. open. [0003] The moving reed is generally an elastic sheet structure, which acts as a current carrier when the circuit is turned on. When the circuit of the magne...
