Abstract
The utility model relates to a large-stroke contact structure capable of fast disconnection. The objective of the utility model is to solve a technical problem of influence on the disconnecting capacity of an existing contact mechanism because of the limitation of the structure of an operating mechanism in the disconnecting of the contact mechanism. The contact structure comprises a base, an operating mechanism, a movable contact and a fixed contact; the base is provided with a supporting component; the fixed contact and the movable contact can both rotate by a certain angle; a rotating component is connected with the fixed contact through a transmission component; the rotating component rotates to synchronously drive the fixed contact through the transmission component, such that the fixed contact can rotate to a rotation direction opposite to the rotation direction of the movable contact, and therefore, the fixed contact and the movable contact can be attached to or separated from each other. According to the contact structure of the utility model, a movable contact/fixed contact synchronous action structure distribution mode is adopted, when switching off is performed, the movable contact and the fixed contact rotate to opposite directions synchronously, and therefore, the speed of the disconnecting between the movable contact and the fixed contact can be increased, and maximum contact stroke between the movable contact and the fixed contact can be increased, and as a result, the disconnecting speed of the contact structure can be effectively improved. The large-stroke contact structure capable of fast disconnection is advantageous in simple structure, high reliability, and fast disconnecting speed.
