Abstract
The utility model relates to a kind of breaker of plastic casing with contact indicating mechanism, comprise the housing be made up of upper cover and base, handle, to be fixed on base and to link the operating mechanism arranged with handle, be arranged on the three groups of contact supportings be connected with operating mechanism in base, be arranged on the moving contact on each contact supporting, corresponding each moving contact place is arranged on the fixed contact on base, described moving contact is hinged on contact supporting, moving contact is provided with spring at pin joint towards between contact supporting side and contact supporting, the pin joint of contact supporting and moving contact is also hinged with connecting rod, the connecting rod other end and indicating arm hinged, on cover corresponding indicating arm formed indicator hole, indicating arm is set in indicator hole.The utility model absorbs the lateral displacement of contact supporting by the swing of connecting rod, guarantees the straight line of indicating arm all the time in indicator hole moves up and down, and improves the accuracy of product.
Description
Technical field
The utility model relates to a kind of breaker of plastic casing, particularly relates to a kind of breaker of plastic casing with contact indicating mechanism.
Background technology
At present, mold cased circuit breaker is for circuit overloads, electric leakage and short-circuit protection, is also applicable to do in alternating current circuit the use that infrequently conversion and motor infrequently start.Existing mold cased circuit breaker in use, whether operator can not differentiate this mold cased circuit breaker easily in running order, only have this residual current circuit breaker of position judgment whether in running order by operating mechanism, if when operating mechanism is malfunctioning, operator is easily misjudgement just, there is potential safety hazard in operation.But, existing mold cased circuit breaker does not possess moving contact deixis mostly, although the circuit breaker of existing transparency cover can see the position of moving contact from the outside, but this circuit breaker is after using for a long time, just have impact on observation, do not see moving contact and fixed contact and whether be in and disconnect or closure state.Although there is part circuit breaker to possess moving contact deixis, there is the too high defect of complex structure, production and processing trouble, cost in its indicating mechanism.
The existing breaker of plastic casing with contact indicating mechanism is generally direct installs an indicating arm on moving contact, indicating arm passes from panel, when this circuit breaker is at separating brake, when stirring handle to open position, the action of handle strip pneumatic operating mechanism, operating mechanism drives moving contact upwards action, realizes separating brake, the indicating arm be connected on contact supporting also moves up with contact supporting, stretches out from indicator hole; When circuit breaker is when closing a floodgate, moving contact moves downward and closes with fixed contact, and indicating arm moves down with contact supporting.In the course of action of whole combined floodgate or separating brake, indicating arm moves up and down with contact supporting, and the movement locus of contact supporting is arc, in the process moved up and down, inevitably there is horizontal movement in indicating arm, can produce certain squeeze and destroy in the process of transverse shifting to housing, and in order to adapt to the transverse shifting of indicating arm, indicator hole can do larger than the diameter of indicating arm, affects the housings close of breaker of plastic casing, also unsightly.
Summary of the invention
The purpose of this utility model is the defect overcoming prior art, provides that a kind of dependable performance, structure are simple, production cost is low, accurately can indicate the breaker of plastic casing of the band contact indicating mechanism of moving contact normal off position.
For achieving the above object, the utility model adopts a kind of breaker of plastic casing with contact indicating mechanism, comprise the housing be made up of upper cover and base, handle, to be fixed on base and to link the operating mechanism arranged with handle, be arranged on the three groups of contact supportings be connected with operating mechanism in base, be arranged on the moving contact on each contact supporting, corresponding each moving contact place is arranged on the fixed contact on base, described moving contact is hinged on contact supporting, moving contact is provided with spring at pin joint towards between contact supporting side and contact supporting, the pin joint of contact supporting and moving contact is also hinged with connecting rod, the connecting rod other end and indicating arm hinged, on cover corresponding indicating arm formed indicator hole, indicating arm is set in indicator hole.
The utility model is set to form guide wall inside described indicator hole further, and guide wall extends inside upper cover.
The beneficial effects of the utility model be indicating arm by rod hinge connection on the contact supporting of breaker of plastic casing, connecting rod two ends respectively with indicating arm and contact supporting hinged, dynamic shake-up combined floodgate and open a sluice gate in process, the lateral displacement of contact supporting is absorbed by the swing of connecting rod, guarantee the straight line of indicating arm all the time in indicator hole moves up and down, transverse shifting can not occur, improve the accuracy of product, contact action instruction is accurate, good looking appearance.
