The utility model content
The purpose of this utility model is to provide a kind of long-term out of doors isolated switch main contact spare of the less circuit breaker combined electrical apparatus of operating physical force when using and using that is suitable for.
To achieve these goals, the isolated switch main contact spare of circuit breaker combined electrical apparatus of the present utility model comprises movable contact assembly and stationary contact spare, and the outside of above-mentioned movable contact assembly is provided with outer cover; The movable contact assembly comprises support, is evenly distributed around the support and is connected a plurality of movable fingertip that the conductive shield of outer cover covers; Between every movable conduction fingertip and outer cover inboard wall of cylinder, be provided with the sheet spring; The static contact finger core of stationary contact spare inserts in the through hole of being made up of described each movable conduction fingertip.
In the technique scheme, evenly be provided with the limit groove that is used for arrangement activity fingertip around the support.
In the technique scheme, the bottom of above-mentioned outer cover conduction cover cap is worker's shape hanging platform, and each movable fingertip of conducting block is hung on described worker's shape hanging platform by its inboard boss in upper end, and described outer cover cover cap is provided with electric-conductor.
In the technique scheme, the outside, the upper end of described movable fingertip is provided with boss, makes its upper end form T shape head, and the outside, lower end of movable fingertip is provided with boss, and above-mentioned spring is arranged between the outside boss of movable fingertip upper and lower end.
In the technique scheme, the end of above-mentioned movable fingertip has the arc transition face; The top end face of static contact finger core is a hemisphere face.
In the technique scheme, support central authorities are provided with the medium pore that can match with described hemisphere face.
Compared with prior art, the utlity model has following good effect: in (1) the utility model, the movable contact assembly and the static contact finger core of isolated switch main contact spare are located in the outer cover, have effectively been slowed down and gone mouldy and generation electric, chemical corrosion; Simultaneously, many in the movable contact assembly evenly are provided with around support movable fingertip and sheet spring, and under the function of current, each movable fingertip shrinks to the center, and the pressure of engagement tabs spring has simultaneously effectively guaranteed contacting of movable fingertip and static contact finger core; On the other hand, also can reduce the pressure requirement of sheet spring, thereby take in sail fingertip and the frictional force of static contact finger core when slide relative, also promptly reduce operating physical force.(2) in the utility model, movable fingertip end is a cambered surface, and the top end face of static contact finger core is a hemisphere face, and be suitable for further taking in sail fingertip and the frictional force of static contact finger core when slide relative can prevent that the two from misplacing simultaneously.
