Abstract
This utility model relates to an operating mechanism and a switchgear having the operating mechanism. The operating mechanism controls the closing and opening actions of a moving contact. It includes a force-applying component, a force-transmitting component, and a force-receiving component. The force-applying component is integrally connected to a force-applying part, and the force-transmitting component is integrally connected to a first force-transmitting part. The force-applying part and the first force-transmitting part cooperate to form a force-applying transmission structure. The force-transmitting component is also integrally connected to a second force-transmitting part, and the force-receiving component is integrally connected to a force-receiving part. The second force-transmitting part and the force-receiving part cooperate to form a force-receiving transmission structure. The force-applying component applies an external driving force and drives the force-transmitting component to move via the force-applying transmission structure. The force-receiving component is connected to the moving contact to drive the moving contact to perform closing and opening actions. This utility model forms a force-applying / force-receiving transmission structure between adjacent parts by integrally connecting the force-applying part, the first force-transmitting part, the second force-transmitting part, and the force-receiving part to the force-applying component, the force-transmitting component, and the force-receiving component, respectively. This results in a transmission between parts with fewer parts and more reliable transmission.
