Abstract
The invention relates to a long-break-distance contact structure capable of breaking rapidly. The long-break-distance contact structure mainly solves the technical problem that when breaking is performed on an existing contact structure, due to limit of an operation mechanism structure, the breaking capacity of the contact structure is affected. The contact structure comprises a base, an operation mechanism, a moving contact and a fixed contact. A supporting part is installed on the base, the fixed contact and the moving contact can both rotate by a certain angle, a rotating part is connected with the fixed contact through a transmission part, and the rotating part rotates to drive the fixed contact synchronously through the transmission part to rotate in the rotating direction opposite to the moving contact so as to form mutual joint or separation. Due to the fact that the structure distribution mode that the moving contact and the fixed contact move simultaneously is adopted in the contact structure, during opening, the moving contact and the fixed contact rotate in the opposite directions at the same time, the breaking speed between the moving contact and the fixed contact is improved, the maximum contact break distance between the moving contact and the fixed contact can be increased, and therefore the breaking speed of the contact structure is effectively improved. The long-break-distance contact structure has the advantages of being simple in structure, high in reliability and rapid in breaking speed.

Embodiment
For accompanying drawing, embodiments of the invention are described further below:
As shown in the figure, a kind of large opening structure of contact terminal of disjunction fast, comprise pedestal 14, operating mechanism 7, moving contact 6, fixed contact 3 and rotating part 8, described moving contact 6 is installed on rotating part 8, described operating mechanism 7 matches with rotating part 8 and drives moving contact 6 to rotate to an angle, described pedestal 14 is provided with terminal block 1, be flexible coupling 2, described fixed contact 3 by be flexible coupling 2 with terminal block 1 integrally welded, on described pedestal 14, supporter 13 is installed, described fixed contact 3 is articulated with on supporter 13 by axle 12, supporter is fixed by screws on pedestal, what described fixed contact 3 can rotate to an angle is installed on supporter 13, between described rotating part 8 and fixed contact 3, by driving member 10, be connected, described rotating part 8 rotations form bonded to each other or separated by driving member 10 Timing Belt dynamic/static contacts 3 towards the direction of rotation rotation contrary with moving contact 6.The driving member 10 is here connecting rod, one end of described connecting rod is hinged with rotating part 8 by the first jointed shaft 9, the other end of described connecting rod is hinged with fixed contact 3 by the second jointed shaft 11, connecting rod two ends link together with moving contact 6, fixed contact 3 respectively by the first jointed shaft 9 and the second jointed shaft 11, form linkage.During use, circuit breaker is by separating brake during to closing operation, and operating mechanism 7 drives rotating parts 8 rotations, rotating part 8 drives moving contact 6 toward combined floodgate direction rotation, and by connecting rod band dynamic/static contact 3 toward combined floodgate direction rotation, dynamic and static contact rotates simultaneously, finally reaches the effect of breaker closing.Circuit breaker is when closing a floodgate sub-switching operation, and operating mechanism 7 drives rotating parts 8 rotations, and rotating part 8 drives moving contacts 6 rotations, and by 3 rotations of connecting rod band dynamic/static contact, makes dynamic and static contact simultaneously toward contrary direction rotation, makes breaker open operation.
