Abstract
The utility model relates to an auxiliary contact switching apparatus of a circuit breaker, wherein the auxiliary contact switching apparatus can be used by cooperation with a universal circuit breaker. The apparatus comprises at least one contact module including a housing; and fitting surfaces that can be cooperated and connected with housings of other contact modules are arranged at the front end surface and the rear end surface of the housing. A module rotating shaft is arranged at the center of the housing and is driven by a central shaft passing through the center of the module rotating shaft. Two pairs of static contacts are arranged at the periphery of the module rotating shaft and are respectively connected with two pairs of wiring terminals arranged at the outer side of the housing. Moving contact sheets that can be rotated with the module rotating shaft are installed on the module rotating shaft; and when the module rotating shaft is rotated, the moving contact sheets enable connection and disconnection switching to be realized between the two pairs of static contacts. According to the utility model, two pairs of contacts that are controlled and switched by a cam are arranged in each contact module; and the structure of the apparatus is compact and the opening and closing can be realized reliably. On the basis of the modular structure, the number of the contacts can be freely expanded; the versatility is strong; and the apparatus can be dismounted easily.
Description
Technical field
The utility model relates to low-voltage electrical apparatus components and parts equipment, is a kind of auxiliary contact switching device shifter that is used with omnipotent breaker, and when breaker closing or separating brake, it exports switching signal.
Background technology
The omnipotent breaker auxiliary contact generally is comprised of the sensitive switch with transfer point at present.The built-in auxiliary contact quantity of circuit breaker, generally be 4 often open 4 normally closed.With the auxiliary contact of transfer point, when the user used, the user only can use a group in one group of sensitive switch often to open or normally closed point, and contact capacity is very little, and it is also very poor to switch simultaneously reliability, does not satisfy more and more higher electricity consumption requirement.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of simple in structure, reliability is high, the auxiliary contact of breaker switching device shifter of highly versatile, easy accessibility.
Auxiliary contact of breaker switching device shifter of the present utility model includes at least one contact module, and described contact module comprises a housing, and the front and rear end of housing is provided with the mating surface that can be connected with the housing of other contact modules; Described housing center is provided with the module rotating shaft, and the module rotating shaft is driven by the central shaft of cross-under at the module spindle central; Module rotating shaft periphery is provided with two pairs of fixed contacts, and two pairs of fixed contacts are connected with two docking line ends of hull outside respectively; Being equipped with in the module rotating shaft can be with the movable contact spring of module rotating shaft rotation, movable contact spring switched conductive or disconnection between two pairs of fixed contacts during module rotating shaft rotation.
The conductive contact surfaces two ends of described fixed contact are provided with lead angle, lead with the incision to movable contact spring.
Described contact module has successively connect a plurality of, and the module rotating shaft cross-under of each contact module is positioned on the outer face of contact module of end and is connected with end cap on same central shaft.
The utility model arranges two pairs of contacts of being switched by cam control in each contact module, compact conformation, deciliter reliable; By the structure of modular, can freely expand number of contacts, its highly versatile, easy accessibility has satisfied the instructions for use of different circuit breakers.
