Operating mechanism and isolating switch

Abstract

Disclosed are an operating mechanism and an isolating switch. The isolating switch includes the operating mechanism. The operating mechanism includes a primary energy storage mechanism and an output shaft, and also a secondary energy storage mechanism. The secondary energy storage mechanism includes a second driving structure and a second energy storage elastic member which are coaxially assembled on the output shaft. The second driving structure includes a fixing member and a locking assembly. The fixing member is provided with two limiting grooves. The primary energy storage mechanism releases energy during an opening process to drive the output shaft to rotate and stores energy for the second energy storage elastic member. After the output shaft drives a locking part of the locking assembly to slide out of one of the limiting grooves and to be unlocked, the second energy storage elastic member releases energy and drives the locking assembly to drive the output shaft to continue rotating to an opening position, and the locking part is driven to slide into the other limiting groove to be locked in a limiting manner. The primary energy storage mechanism and the secondary energy storage mechanism drive the output shaft to rotate twice, such that a contact mechanism can be driven to have a larger opening distance during the opening process, which is conductive to ensuring an electrical performance of the product.
