Description
Technical field
The present invention relates to a kind of chopper, in particular, relate to a kind of breaker of plastic casing.
Background technology
Breaker of plastic casing can automatically cut off electric current after electric current exceed escape setting, breaker of plastic casing includes the shell that plastic insulation is made and the control assembly being arranged at enclosure, breaker of plastic casing has generally included overload delay protection and short circuit two kinds of functions of instantaneous protection, overload delay protection, namely it is make double, two gold plaque deformation by thermal conductance, when chopper transships, it is overheated so that double, two gold plaque flexural deformations to produce, thus touching draw bar rotation to realize tripping, this tripping mechanism is usually provided with inclined-plane adjusting rod on draw bar, the lateral attitude of adjusting rod is regulated by knob, then also just have adjusted the distance regulated between screw on inclined-plane and bimetal leaf, short circuit instantaneous protection, when being namely short circuit, the electric current uprushed makes the dynamic iron core on draw bar and static iron core be separated, thus disconnecting circuit.
Breaker of plastic casing of the prior art generally only has a draw bar, the top of this draw bar, namely corresponding with regulating screw position is provided with adjustment adjusting rod, the bottom of draw bar is provided with dynamic ferrum core, reason due to this unitary design, moment threads off and the adjustment of delayed releasing can influence each other, when breaker of plastic casing dispatches from the factory debugging, usually instantaneous function debugging accurately rear delay function is just inaccurate, so debugging for breaker of plastic casing is one and bothers very much troublesome process in production process, cause the problem that production efficiency is low, and so it is difficult to ensure that the precision of instantaneous trip and delayed releasing, moment tripping function and delayed releasing function do not mix up the service behaviour when breaker of plastic casing easily affecting the later stage uses.
Summary of the invention
For the deficiency that prior art exists, it is an object of the invention to provide a kind of breaker of plastic casing being provided with time delay draw bar and instantaneous draw bar, described time delay draw bar and instantaneous draw bar are separate, the purpose being independent of each other when reaching to regulate instantaneous trip and delayed releasing function, facilitates the debugging of dispatching from the factory of breaker of plastic casing.
For achieving the above object, the technical scheme is that a kind of breaker of plastic casing, including housing, described enclosure interior is provided with traction component, regulate screw, bimetal leaf and static iron core, described adjustment screw is fixing with bimetal leaf to be connected, described static iron core fixes the lower section being connected and being positioned at bimetal leaf relative to adjustment screw with bimetal leaf, described traction component includes instantaneous draw bar and time delay draw bar, described instantaneous draw bar includes dynamic iron core and fixing axle, the position of described dynamic iron core is corresponding with static iron core, axial restraint between described fixing axle and housing, what described time delay draw bar was movable be arranged on instantaneous draw bar and described time delay draw bar can move along the setting direction of instantaneous draw bar, on described time delay draw bar, the position corresponding to regulating screw is provided with and regulates the inclined-plane that screw interacts.
The present invention is further arranged to: be wholely set slipping part on described fixing axle, described slipping part is positioned at the opposite side of fixing axle relative to dynamic iron core, described time delay draw bar is provided with slide block, arranges in gap between described slide block and time delay draw bar and the thickness of described gap length and slipping part is suitable and described slipping part is embedded in gap.
