Abstract
The utility model discloses an installing structure of a contact rotating shaft of a circuit breaker, which comprises a contact rotating shaft and a casing, wherein both ends of the contact rotating shaft are installed in pin holes on the casing through shaft pins, annular bulges are arranged along the peripheries of the pin holes on an inner wall of the casing and the end face of the contact rotating shaft is provided with flutes which are matched with the annular bulges. Since the contact surface between the contact rotating shaft and the casing is only limited at the contact parts between the contact rotating shaft and the annular bulges, the contact area is small and the frictional force is lowered. The utility model also discloses another installing structure of the contact rotating shaft of the circuit breaker, which comprises a contact rotating shaft and a casing, wherein both ends of the contact rotating shaft are installed in pin holes on the casing through shaft pins, the end face of the contact rotating shaft is provided with annular bulges which are coaxial with the shaft pins and an inner wall of the casing is provided with flutes which are matched with the annular bulges.
Description
Technical field
The utility model relates to a kind of contact rotating shaft with circuit breaker and is installed in mounting structure on the housing.
Background technology
In some circuit breakers, movable feeler lever in the contact system is mounted in the rounded contact rotating shaft, the two ends of contact rotating shaft are installed in rotation on the housing, the contact rotating shaft also is connected with operating mechanism, under the drive of operating mechanism, the contact rotating shaft is rotated and moving contact separated or closure with fixed contact.In existing circuit breaker, the whole end face of contact rotating shaft contacts with the inwall of housing, and contact-making surface is very big, and frictional force is also big, and the operating physical force that needs operating mechanism to apply during divide-shut brake is bigger, so the divide-shut brake underaction.
The utility model content
The technical problems to be solved in the utility model provides a kind of mounting structure of contact of breaker rotating shaft, and the frictional force of this mounting structure is little, can make the divide-shut brake of circuit breaker more flexible.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of mounting structure of contact of breaker rotating shaft, comprise contact rotating shaft and housing, the two ends of contact rotating shaft are installed in the pin-and-hole on the housing by pivot pin, wherein the periphery of inner walls upper edge pin-and-hole is provided with annular projection, and the end face of contact rotating shaft is provided with the groove that cooperates with annular projection.
In the utility model, the contact rotating shaft only is confined to the position that annular projection contacts with the contact rotating shaft with the contact-making surface of housing, and contact area is very little, greatly reduces frictional force.
As the preferred version of technique scheme, be matched in clearance between the periphery of annular projection on the housing and contact rotating shaft groove.Make like this between contact rotating shaft and the housing relatively rotate more flexible.
In order to solve the problems of the technologies described above, the utility model can also adopt another technical scheme: a kind of mounting structure of contact of breaker rotating shaft, comprise contact rotating shaft and housing, the two ends of contact rotating shaft are installed in the pin-and-hole on the housing by pivot pin, wherein the end face of contact rotating shaft is provided with the annular projection coaxial with pivot pin, and inner walls is provided with the groove that cooperates with annular projection.
As the preferred version of technique scheme, be matched in clearance between the annular projection on the described contact rotating shaft end face and the periphery of the groove on the inner walls.Make like this between contact rotating shaft and the housing relatively rotate more flexible.
