Title:

ROTATING DUAL BREAK POINT CONTACT

Document Type and Number:

WIPO Patent Application WO/2015/043423

Kind Code:

A1

Abstract:

Disclosed is a rotating dual break point contact, comprising: a rotor support (102), a first shaft (103), a second shaft (104), a third shaft (105), a first connecting rod (106), a second connecting rod (107), a contact bridge (108) and a contact spring (109). The contact bridge is provided in the rotor support, the contact bridge rotates relative to the rotor support by means of the first shaft, the second shaft, the third shaft, the first connecting rod, and the second connecting rod, and the contact bridge rotates between an initial pressure position and a maximum expanded position. The number of contact springs is one, which is mounted at one side of the contact bridge, and is located in the rotor support. The rotating dual break point contact has a simple structure, high reliability, and uses the provision of an included angle of a waist-shaped hole and a contact point to keep the pressure of contacts at two sides of a contact bridge balanced, and using a single spring structure makes the structure of the rotating dual break point contact more compact and the volume smaller.
