Known, this release mechanism is hidden by housing, so that the mechanism that protection is in wherein is not subjected to external action.These rotor cases are often made integratedly, so that the lowland keeps expense and the complexity that housing is made as far as possible.Yet for example known from DE 198 36 754 A1, use manifold rotor case around this release mechanism.As from known the above-mentioned document, in this manifold housing, for example use hood-like solid, described hood-like solid is fixed to one another and surround described release mechanism.
The disadvantage of known rotor case is that it is being restricted aspect its complexity when single part is made.Two-part if desired housing, that just must guarantee the supporting of enclosure interior and the locking of housing with expending.Not only need extra installation steps for this reason, and for the structural design of each casing member, also need higher complexity.
Summary of the invention
The objective of the invention is, in electric switch equipment, eliminate the aforesaid drawbacks of known rotor case at least in part.Task particularly of the present invention is, a kind of this in other words electric switch equipment of rotor case, this switching device of the release mechanism that is used for the switching device that electric switch equipment uses and the method that is used for installation switching device are provided, and described rotor case, switching device, electric switch equipment and method are tied a kind of possibility of multipart case and compact as far as possible make in mode cost economy and simple.
Aforementioned purpose is by realizing by rotor case of the present invention, the switching device with the described feature of claim 12, the method that has the electric switch equipment of the described feature of claim 14 and have a described feature of claim 15 by claim 1 is described.Further feature of the present invention and details are by obtaining in dependent claims, specification and the accompanying drawing.This in conjunction with by the described feature of rotor case of the present invention and details certainly also in conjunction with by method of the present invention, be suitable for by electric switch equipment of the present invention and by switching device of the present invention and correspondingly vice versa, thereby cross-reference in other words can cross-reference all the time about the disclosure of relevant single inventive aspect.
Be provided for release mechanism on the switching device that electric switch equipment uses by rotor case of the present invention.Particularly described electric switch equipment is a circuit breaker compact circuit breaker in other words.Have first casing member and second casing member by rotor case of the present invention, described first casing member and second casing member are formed for admitting the housing inner room of release mechanism each other.Described housing inner room be formed in the complete closed that this not only is understood as this inner room.Or rather, also leave opening in other words in one of casing member between described casing member after constituting the housing inner room, for example the joint of described release mechanism or mechanical component can pass or guide described opening.
Be characterised in that by rotor case of the present invention Connection Element makes two casing members fixed to one another partly.Connection Element has the axle section of at least a portion that is used for supporting rotatably release mechanism.In other words, cause the combination of at least two kinds of functions by rotor case of the present invention.Therefore, described Connection Element has also satisfied a kind of subfunction except its elementary task that casing member is coupled together, that is to say at least a portion that supports described release mechanism rotatably.These two kinds of functions must also produce by corresponding independent member apart from each other and thus for known rotor case, and to have saved structure space and member by mode of the present invention by the combination of these two kinds of functions and also to have provided cost savings thus.
" fixed to one another partly " is understood as about described two casing members, and these casing members can not separate owing to described Connection Element again.
Certainly, for example can also realize that two casing members rotate relative to one another, yet described relative rotation for example can stop the stopper section in other words by extra bearing-surface.Preferably, it is fixed to one another that described Connection Element is used in axial direction making two casing members.Further preferably, described casing member also stops by Connection Element with the moving of mode of translation each other.Particularly preferably, described two casing members for example are connected fixed to one another partly along all direction of relative movement by the form fit connection by described Connection Element in other words by power transmission.
The axle section that is used for swivel bearing is preferably designed to axle and therefore has circular circular basically in other words cross section.Described axle section is used for supporting rotatably at least a portion of described release mechanism.Particularly on described axle section in direct mode or support the cable bridge of described release mechanism rotatably in indirect mode.For this reason, described Connection Element, particularly a section are preferably made by the respective material with necessary mechanical stability.It for example can be metal, especially steel.Therefore for example can use stainless steel or common steel with corresponding corrosion-inhibiting coating.
The advantage of the combination results by described Connection Element and rotational supporting structure is, the mechanical stability that is used for necessity of rotational supporting structure simultaneously also can be for use as for being used to make described casing member connection stability factor fixed to one another partly.Thus with for example by means of the interlock-setting element that is made of plastics fixed to one another, known multipart case element compare, can also obtain higher mechanical stability, and not produce surcharge.Even complexity and manufacturing cost have been reduced.
Certainly, also can consider plural casing member within the scope of the invention, it is fixed to one another partly that described casing member particularly all, the picture of can saying so passes through described Connection Element along pearl chain.Described fixing realizes by described Connection Element directly preferably that for two outmost casing members the casing member that is between it is then fixed to one another partly by Connection Element indirectly by adjacent casing member.
In addition, maybe advantageously, for described Connection Element, to note corresponding match materials with the part that is rotated supporting of described release mechanism.For this reason, for example the part of described Connection Element, especially described axle section can be provided with corresponding fine surface structure, wear and tear in other words so that reduce this lip-deep frictional force.
Maybe advantageously, in pressing rotor case of the present invention, described Connection Element particularly has first supporting device and second supporting device on its opposed end.These two supporting devices are configured to described rotor case is bearing in first bearing and second bearing of described switching device rotatably.This swivel bearing for example can by will insert as the axle journal of supporting device in the described switching device corresponding groove in other words recess realize in the peviform structure in other words.In other words, by this execution mode, in by rotor case of the present invention, provide the third function by described Connection Element.Except linkage function be used for the elementary supporting functions of a part of release mechanism, provide extra in this embodiment, can say so secondary, be used for of the supporting of whole rotor case to external switching device.Supporting about the parts of described release mechanism also can be referred to " interior support ", and the supporting in switching device also can be referred to " external support " about described rotor case.This complexity and while of further having reduced the design of described rotor case especially provides higher flexibility higher in other words function concentration degree in by rotor case of the present invention in Connection Element.Supporting device is for example as head or be formed on as bolt on one or two ends of Connection Element.Especially at this axial projection that relates to described Connection Element member of axle journal shape in other words.On the end that especially is arranged on Connection Element, reduced by the power that causes in the supporting structure, particularly support moment.In addition, can keep the necessary structure space that is used for this Connection Element especially compactly.
