Description

The operating means that has integral spring element of dust catcher
Technical field
The present invention relates to a kind of as claim 1 dust catcher that has the operating means that is used to activate electric component as described in the preamble.
Background technology
By EP 1047333 B1 a kind of dust catcher that has the operating means that can enter from hull outside is disclosed, this operating means control connection/off switch and potentiometer.Disposed a common action button at this for described connection/off switch and potentiometer, it axially-and the rotation be arranged in movingly on the housing of dust catcher, wherein connect/operation of off switch, adjust the operation of the potentiometer that is designed to rotating potentiometer by rotatablely moving of action button by the axial motion adjustment of action button.Be provided with the action bars that separates with action button and be used for position the resetting to high position of action button from depressing.Action bars there is arranged on the plastic fixtures, and this plastic fixtures is bearing on the wiring board of electric component of dust catcher.But shortcoming in this case is, spring force can import wiring board by the elasticity pretension of action bars.The spring force that imports may cause material stress in wiring board, this material stress may cause the solder joint fracture of printed conductor or electric component.Consequence is the operating trouble that produces dust catcher.
Summary of the invention
Task of the present invention is to design a kind of as before chatting the described dust catcher of part reliably.
This task solves thus according to the present invention, and flexible member and operating means are one, and the free end of this flexible member is bearing on the circuit orbit on the abutment wall of housing parts slidably.
By the supporting of free end on the abutment wall of housing parts of described flexible member, the spring force that is caused by flexible member is directed in the housing, and the stress that causes with regard to the spring force that does not have flexible member imports in the wiring board like this.Owing to do not have undesirable power to import in the wiring board, the reliability when just having avoided the functional fault of dust catcher and having improved the dust catcher operation.The design of flexible member and operating means one is additional advantages of the present invention, and dust catcher can be produced in the mode of cost economy thus.Be molded in other words on the operating means because flexible member has been constructed, just cancelled the installation step that is used for fixing flexible member separately between operating means and housing.By the sliding bearing of free end on the abutment wall of housing parts of flexible member, axial pretightning force is imported in the operating means reliably, although the flexible member of moulding is wherein arranged, the performance that rotatablely moves of operating means still keeps fully.
In a kind of preferred design of the present invention, flexible member is the leaf spring that arches in the plane parallel with the pivot center of operating means.The flexible member of this leaf spring shape has free end at this, this free end can be designed to the form of slide block, import in the housing parts of dust catcher by flexible member in the power that axially imports in the operating means so on the one hand, simultaneously on the other hand the free end of the slide block shape of flexible member when operating means rotates above a bottom surface of housing parts on a circuit orbit along slip, the rotatable motility of operating means can be not restricted because of flexible member like this.The orientation that described leaf spring arches in the plane parallel with pivot center has caused, the elastic movement of flexible member always with the tangent plane of rotatablely moving of operating means in carry out.The structure of arching of described flexible member realizes by at least one curved stretch section at an angle.The described flexible member that arches can be designed to have a sweep, has so just produced the flexible member of a U-shaped structure.The replacement scheme of the track that arches of described flexible member also can realize having on the track of flex point, that is to say, at least twice counter-rotating is set, and so just produces a S shape or Z-shaped structure.Also be enough in a kind of simple structure of described flexible member, a straight ligulate leaf spring promptly only is set, the bottom surface of the relative housing parts of this spring is extended distribution at an angle, realizes spring with the bending by the ligulate leaf spring.
The abutment wall of described flexible member can be installed with operating means advantageously by the bottom surface formation of a cup-shaped support on the housing parts in this bearing.Basically the cylindrical configuration of operating means is significant to glitch-free the rotatablely moving property of operating means.Needn't necessarily have the cylindrical outer surface of sealing at this operating means, but that a central axis segment of operating means has disposed the end face of two circles is just enough, on the circular periphery edge of described end face, can have obtained the supporting of rotatable motion.Bearing on the housing parts should be designed to cup-shaped to be used for the coupling of columniform operating means.The housing parts structure of preferred hollow cylinder in cup-shaped can especially accurately be installed ordinatedly at columniform operating means described in this structure.Cup-shaped support and columniform operating means have constituted the guiding of operating means in housing parts at this and have supported in other words, like this operating means around it central axis rotationally and axially slidably the supporting.Described cup-shaped support needn't necessarily be designed to the cylinder that seals at this, but breach or perforation can be set.Bearing on the housing parts of the bearing pedestal shape of at least two annulars is also enough, and this bearing at least surrounds the circle ring disk of end face with supporting.Concerning cup-shaped support, needn't there be abutment wall separately the bottom surface of cup-shaped support that housing parts preferably is set so again as the free-ended abutment wall of flexible member between bearing and operating means.
In a kind of preferred design of cup-shaped support, this bearing has the columniform side wall sections that has inwardly outstanding projection, operating means about it profile and the arresting disc of described columniform side wall sections coupling resting in this above projection when installing with the position, angle of correct stagger angle position deviation, when installing, then slip over this projection with correct stagger angle position.Said arresting disc is preferably designed to disc and is provided with a breach in certain position.Inwardly stretch out an outstanding projection to cup-shaped support from the inboard of the cylindrical side wall of cup-shaped support.Breach on the shape of described outstanding projection and the arresting disc of operating means mates on shape and size.If operating means is to pack in the cup-shaped support with the position, angle of correct stagger angle position deviation, then the outward flange of circular arresting disc slides along the cylindrical side wall of cup-shaped support, above arresting disc is accommodated to inwardly outstanding projection.In the stagger angle position of such mistake, this operating means can not fully axially be inserted into its service position in cup-shaped support.Has only operating means like this after the axis rotation around it, be after the outstanding projection of cylindrical side wall of breach and the cup-shaped support of arresting disc is aimed at, arresting disc could be crossed inwardly outstanding projection along cylindrical side wall and continue to slip in the cup-shaped support, reaches its service position with its correct stagger angle position up to operating means.If second electric component is designed to the value that each turned position of rotating potentiometer and operating means must dispose a definite rotating potentiometer, the position of then described correct stagger angle will be paid special attention to.Be that operating means can only be pulled down from cup-shaped support in its position of correct stagger angle equally according to inwardly outstanding projection of the present invention and another advantage of the breach on the arresting disc.Guaranteed that thus although pulled down operating means, second electric component rotating potentiometer in other words still occupies its correct installation site, also can meet again in the cup-shaped support of packing into functionally at this position operation device.
Described preferred embodiment in, arresting disc is designed to disc and has a breach with projection coupling.Except with unique breach of unique projection coupling, also can be provided with evenly a plurality of or be distributed in the breach projection on the cylindrical side wall of cup-shaped support in other words on the circumference of arresting disc unevenly.
In the friendly scheme of a kind of special assembling of the present invention, cup-shaped support can have at least one grab, and this grab tightens the arresting disc of operating means in the installation site.Can slip over grab when operating means is axially packed cup-shaped support into, operating means can reach the grab back with having no problem and occupy its predefined installation site like this.Be fixed at least one grab back then, operating means can not take out from cup-shaped support when not unclamping in advance or damaging grab more like this operating means chucking.At least one grab axially being arranged vertically on the cylindrical side wall of cup-shaped support is preferred in other words selects like this for arresting disc, i.e. flexible member or at every turn all do not have pretension is in the cup-shaped support of perhaps always seamlessly packing under very little pretension.Basically should stop at this, operating means can produce undesirable knocking noise like this axially there not being spring pretension and fixing with a gap.To avoid on the other hand, be under the tangible pretension in the resting position of operating means with operating means design all-in-one-piece flexible member.The too high elasticity pretension that especially when plastic material is used in the design of flexible member and operating means one, should stop flexible member in the resting position of operating means.A high elasticity pretension that continues to exist on plastic resilient elements will continue to cause the fatigue of flexible member, and the elasticity pretension of operating means will run off along with the time like this.Therefore the upright position of the physical dimension of flexible member and arresting disc and grab is harmonious so mutually is favourable, although promptly operating means is essentially no fixing with gap, flexible member remains under the as far as possible little elasticity pretension in the resting position of operating means on the other hand.
In a preferred embodiment of the present invention, arresting disc has and is used to operate the end face of first electric component and the axial journals that is used to operate second electric component.Be preferably designed to connection/off switch at this first electric component, second electric component is designed to rotating potentiometer.But according to the applicable cases and the structure of dust catcher, it also is significant that a plurality of in other words switching stages of connection/closing function obtain by rotary switch, and this rotary switch links to each other with the axial journals that is used to operate second electric component.For example the axial operation by operating means also can realize the function that will control continuously, for example power adjustments of dust catcher in another flexible program.So for example can be by button of following press operation of operating means, this button links to each other with an electronic controller, and described electronic controller continues to improve the power of dust catcher when button down, decontrol again up to operating means.The downward adjusting of dust catcher power for example can be regulated by the drawing on operating means, and by the drawing operation another one button of operating means, this button links to each other with electronic controller and also correspondingly regulates the power of dust catcher downwards for this reason.The connection of dust catcher/for example close and to obtain by the rotary switch of axial journals operation that utilizes operating means by the rotatable adjustment of operating means with a definite angle.
In a kind of mode of the production abnormal cost economy to dust catcher, flexible member, arresting disc and/or axle journal are molded on the operating means made from plastic injection-moulded method.By the moulding of flexible member, arresting disc and/or axle journal one, reduced the part diversity on the one hand, simplified assembling on the other hand, because cancelled the installation step of separating that is used for fixing flexible member, arresting disc and/or axle journal.
Flexible member can have at least one punctured position, is used for its variable adjustment from operating means removal or spring force.Said punctured position can be preferably forms in the stiff end of flexible member and the transitional region between the shaping position on the operating means.In order to remove flexible member from operating means, described punctured position is so-called theoretical fracture position.Crossover position place between flexible member and operating means, the cross section of working of plastics has been reduced, that is to say, it has carried out the attenuate of a material thickness, like this when the crooked elastic characteristic that surpasses it of flexible member, flexible member preferably this theoretical fracture position in other words punctured position disconnect from operating means.If flexible member should have the stronger pretightning force or the life-span of raising in a kind of flexible program of dust catcher, then the flexible member of moulding for example is significant from the removal on the operating means.Then just can, the preformed flexible member of one on operating means that is provided with in basic flexible program is by a flexible member that separates, for example a metal coil spring (Federwendel) is replaced.For what separate, preferable alloy is helical spring fixing, on operating means moulding bearing, metal coil spring can be inserted in above it when assembling.One is separated, and the preferable alloy helical spring not only can use with substitute mode after removing the moulding plastics spring, and can be additional to integrated spring and be installed on the operating means.Described punctured position not only can be as the theoretical fracture position of removing the flexible member of moulding from operating means.Punctured position for example also can be used for the adjustment of setting of spring force of the flexible member of moulding.This moment, the spring force of flexible member was not that shape, structure and position by the free element of flexible member produces basically, but produced by the rigidity of punctured position, and it is similar to a film hinge and works at this.When the punctured position attenuate, reduce spring force, and when punctured position thickens, produced the spring performance of stronger flexible member.The present invention describes by unique flexible member.But also two or more flexible members can be set on operating means.
