Title:
OPERATING MECHANISM AND ISOLATING SWITCH
Document Type and Number:
WIPO Patent Application WO/2023/226909
Kind Code:
A1
Abstract:
An operating mechanism and an isolating switch. The isolating switch comprises the operating mechanism. The operating mechanism comprises a primary energy storage mechanism and an output shaft, and further comprises a secondary energy storage mechanism, wherein the secondary energy storage mechanism comprises a second driving structure and a second energy storage elastic member which are coaxially assembled on the output shaft; the second driving structure comprises a fixing member and a locking assembly; the fixing member is provided with two limiting grooves; and during switching off, the primary energy storage mechanism releases energy to drive the output shaft to rotate, so as to store energy for the second energy storage elastic member, after the output shaft drives a locked portion of the locking assembly to slide out of one limiting groove to be unlocked, the second energy storage elastic member releases energy to drive the locking assembly to drive the output shaft to continue rotating to a switching-on position, and the locked portion is driven to slide into the other limiting groove to be limited and locked. The primary energy storage mechanism and the secondary energy storage mechanism separately drive the output shaft to rotate, so that a contact mechanism can be driven to have a larger opening distance during switching on, thereby being beneficial for ensuring the electrical performance of a product.
