(54) Vlppeafbryder af typen, der er uadskillelig fastgjort til led* ningen.(54) Flip switch of the type inseparably attached to the line.

Opfindelsen angår en vippeafbryder af den i krav lfs indledning angivne art.The invention relates to a rocker switch of the kind specified in the preamble of claim 1.

Det er almindeligt,at afbrydere af denne art monteres i tilslutnings-ledninger for bord- eller gulvlamper eller andet elektrisk lavspmn-dingsudstyr med et forholdsvis beskedent effektforbrug.It is common for circuit breakers of this kind to be mounted in connection wires for table or floor lamps or other low voltage electrical equipment with a relatively modest power consumption.

Q Idet sådanne afbrydere er beregnet til at hæge frit i vedkommende ") ledninger og danne såvel mekanisk som elektrisk forbindelse mellem D ledningsafsnittene på begge sider af af skryderen, er det rigtigt, at afbrydere af drøne art er lette og har ringe omfang. tQ Since such switches are intended to raise freely in the wires concerned and form both mechanical and electrical connection between the D wiring sections on both sides of the bridges, it is true that the switches of the drone type are light and of small size.

Dette gælder især, når afbryderen er af engangstypen, som iwcg i 2 143823 er beregnet til udskiftning, idet den er kombineret med den tilhørende ledning til en fast enhed.This is especially true when the disposable circuit breaker is intended for replacement as it is combined with the associated wiring for a fixed unit.

Kendte afbrydere af den foreliggende art har imidlertid et tværsnit, som er uforholdsmæssigt større end tværsnittet af den tilhørende ledning, hvilket gør kombinationen af afbryder og ledning klodset og uhåndterligt samt giver den et mindre tiltalende udseende. Det store tværsnit bevirker naturligvis også, at afbryderens vægt bliver tilsvarende større.Known switches of the present kind, however, have a cross-section which is disproportionately larger than the cross-section of the associated wire, which makes the combination of switch and wire clumsy and unmanageable and gives it a less appealing appearance. Of course, the large cross section also causes the switch's weight to be correspondingly larger.

Det er derfor formålet med den foreliggende opfindelse at tilvejebringe en vippeafbryder af engangstypen med nedsat omfang og vægt i forhold til kendte konstruktioner.It is therefore the object of the present invention to provide a disposable rocker switch of reduced size and weight in relation to known constructions.

Dette opnås ifølge opfindelsen ved, at den indledningsvis angivne vippeafbryder er ejendommelig ved det i krav l1s kendetegnende del angivne.This is achieved according to the invention in that the rocker switch initially indicated is characterized by the characterizing part of claim 1.

Forbindelsesstykket danner således en elektrisk ledende forbindelse mellem knastens koblingsstykke og strømlederen, som er tilsluttet den ene ledertråd, samtidigt med det sammen med nævnte koblingsstykke og strømleder udgør en meget enkel og ringe pladskrævende smækanordning, som sørger for at knasten altid bringes til en af de to stabile stillinger, og desuden, i modsætning til kendte anordninger til dette formål, muliggør en montering i forlængelse af knastens længderetning, i stedet for på konventionel måde under knasten. Det er klart, at de ovenfor angivne træk gør det muligt at reducere afbryderens tværsnit i væsentlig grad uden en tilsvarende forøgelse af dens længde, således at også afbryderens vægt nedsættes. I denne sammenhæng skal det også påpeges, at det af praktiske og æstetiske hensyn er af største betydning at nedbringe afbryderens dimensioner på tværs af ledningen, da længdedimensionen flugter med den tilsluttede ledning og således ikke er så kritisk.Thus, the connector forms an electrically conductive connection between the cam coupler and the power conductor connected to one conductor, together with the coupler and power conductor, constituting a very simple and low space-demanding slab which ensures that the cam is always brought to one of the two stable positions, and furthermore, contrary to known devices for this purpose, allow an extension in extension of the longitudinal direction of the cam, instead of in conventional manner under the cam. It will be appreciated that the above features enable the cross-section of the switch to be substantially reduced without a corresponding increase in its length, so that the weight of the switch is also reduced. In this context, it should also be pointed out that for practical and aesthetic reasons, it is of the utmost importance to reduce the dimensions of the circuit breaker across the conduit, since the length dimension aligns with the connected conduit and thus is not so critical.

Opfindelsen skal i det følgende nærmere forklares med henvisning til tegningen, hvor: fig. 1 viser vippeknasten med den tilhørende smækanordning for en udførelsesform af en vippeafbryder ifølge opfindelsen, set fra siden, 3 U3S23 fig. 2 viser på lignende måde en anden udførelsesform ifølge opfindelsen, fig. 3 viser på lignende måde en tredie udførelsesform ifølge opfindelsen, og fig. 4 viser den i fig. 3 viste udførelsesform set ovenfra og delvis i snit.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail with reference to the drawing, in which 1 is a side view of the rocker box with the associated tapping device for an embodiment of a rocker switch according to the invention; FIG. 2 similarly shows another embodiment of the invention; FIG. 3 similarly shows a third embodiment of the invention, and FIG. 4 shows the one shown in FIG. 3 as seen from above and partly in section.

I fig. 1 er der vist en vippeknast V med et kontaktstykke K og en smækanordning for en afbryder i henhold til opfindelsen, idet nævnte smækanordning består af en udragende elastisk tunge T fra vippeknastens kontaktstykke K, en strømleder SI med en indbukning H2, samt et stift ledende forbindelsesstykke F i form af en lige stav, hvis ene ende ligger an mod bunden af indbukningen H2, og hvis anden ende er forsynet med et smalt fremspring f, som er ført gennem en gennemgående udskæring Hl i tungen T.In FIG. 1, a rocker V is shown with a contact piece K and a switching device for a switch according to the invention, said slider comprising a protruding elastic tongue T from the rocking contactor K, a current conductor S1 with a bend H2, and a rigid conductive connection piece F in the form of a straight rod, one end of which abuts the bottom of the indentation H2, and the other end of which is provided with a narrow projection f, which is passed through a through-cut H1 in the tongue T.

Knasten er i sin centrale del udstyret med en udskæring U, som er hensigtsmæssigt lejret på en kiletap A og udformet således, at knasten V kan smækkes mellem to stabile stillinger, nemlig en første stilling, som er vist med fuldt optrukne linier i fig. 1 og tilsvarende åben afbryder, samt en anden stilling, som er vist med punkteret linie og svarer til lukket afbryderstilling, idet den fjedrende bagkant af kontaktstykket K kommer til anlæg mod en anden strømleder S2. Strømlederne SI og S2 er tilsluttet hver sin led-ningsende (ikke vist), når afbryderen er monteret i en elektrisk ledning.The cam is in its central part provided with a cutout U, which is conveniently mounted on a wedge pin A and designed so that the cam V can be slammed between two stable positions, namely a first position, which is shown with fully drawn lines in FIG. 1 and corresponding open switch, as well as another position, which is shown in dotted line and corresponds to the closed switch position, with the resilient rear edge of the contact piece K coming into contact with another current conductor S2. The current conductors S1 and S2 are each connected to a wiring end (not shown) when the switch is mounted in an electrical wire.

Det er spændkraften i tungen T, som driver smækningen af knasten mellem de to stabile stillinger og sørger for en vis stabiliseringskraft i disse stillinger samt det nødvendige kontakttryk mod strømlederen S2 i afbryderens lukkede stilling. Nævnte spændkraft vil til enhver tid være rettet langs forbindelsesstykket F for at give spænding mod bunden af indbukningen H2 på den stive strømleder SI. Det vil fremgå af fig. 1, at forbindelsesstykket F er rettet på hver sin side af knastens vippeakse ved spidsen af kileknasten A, i de respektive stabile stillinger.It is the tension force in the tongue T which drives the thrust of the cam between the two stable positions and provides some stabilizing force in these positions as well as the necessary contact pressure against the conductor S2 in the closed position of the switch. Said tension force will at all times be directed along the connecting piece F to provide tension to the bottom of the bend H2 on the rigid current conductor S1. It will be apparent from FIG. 1, that the connecting piece F is directed on either side of the tilt axis of the cam at the tip of the wedge axle A, in the respective stable positions.

Den udførelsesform, som kun i en stilling er vist i fig. 2, adskiller 4 143823 sig kun fra udførelsesformen i fig. 1 ved,at forbindelsesstykket F er forsynet med en elastisk udbukning, som giver yderligere spændkraft i forbindelsesstykkets retning i tilslutning til den elastiske kraft i tungen T. I fig. 2 er tilsvarende dele iøvrigt forsynet med samme henvisningsbetegnelser som i fig. 1.The embodiment shown in one position only in FIG. 2, 4 143823 differs only from the embodiment of FIG. 1 in that the connecting piece F is provided with an elastic deflection which provides additional tension force in the direction of the connecting piece in connection with the elastic force in the tongue T. In FIG. 2, corresponding parts are otherwise provided with the same reference numerals as in FIG. First

I fig. 3 er vist en yderligere udførelsesform med principielt samme virkemåde, men hvori en strømleder er forsynet med en U-formet bladfjeder, som sørger for den nødvendige spændkraft langs forbindelsesstykkets F, som er stift anbragt mellem et ben af bladfjederen og et stift kontaktstykke K, ved hjælp af fremspring fl og f2, som er indført i hver sin gennemgående udskæring Hl og H2 i henholdsvis strømlederen SI og kontaktstykket K. Tilsvarende dele er iøvrigt forsynet med samme henvisningsbetegnelser som i fig. 1 og 2.In FIG. 3, there is shown a further embodiment having basically the same operation, but in which a current conductor is provided with a U-shaped leaf spring which provides the necessary tensioning force along the connection piece F, which is rigidly placed between a leg of the leaf spring and a rigid contact piece K, at by means of protrusions f1 and f2, which are inserted in their respective cut-out H1 and H2 in the current conductor S1 and the contact piece K. The corresponding parts are otherwise provided with the same reference numerals as in fig. 1 and 2.

Fig. 4 viser udførelsesformen i fig. 1 set ovenfra, delvis i snit.FIG. 4 shows the embodiment of FIG. 1 is a top view, partly in section.

Her er det vist,hvorledes den ledning L, som afbryderen er ophængt i, er indklemt mellem afbryderens sidestykker Dl og D2, idet ledningens ydre isolation er svejset til sidestykkerne ved hjælp af tilført ultralydenergi til opvarmning af de flader, som skal sammenføjes. Indvendig i afbryderen er den ene af ledningens to ledere 1 1 og 1 2 afbrudt og dens lederender N afisoleret til fæste henholdsvis til strømlederen SI ved hjælp af en klemanordning C, og til strømlederen S2 (ikke vist i fig. 4). Den anden indvendige leder 1 2 i ledningen L er ført ubrudt og isoleret gennem afbryderen i længderetningen.Here it is shown how the line L in which the switch is suspended is clamped between the switch parts D1 and D2, the outer insulation of the cable being welded to the side pieces by the application of ultrasonic energy to heat the surfaces to be joined. Inside the switch, one of the two conductors 1 1 and 1 2 of the wire is disconnected and its conductor ends N are insulated for attachment to current conductor S1 by means of a clamping device C, and to current conductor S2 (not shown in Fig. 4). The second internal conductor 1 2 of the line L is routed uninterrupted and isolated through the longitudinal switch.

Af fig. 4 fremgår det endvidere, at forbindelsesstykket F, således som tidligere beskrevet under henvisning til de øvrige figurer, er ført mellem forbindelsespunkter henholdsvis på en fjedrende tunge T på vippeknastens koblingsstykke og på strømlederen SI, som er tilsluttet lederenden N for lederen 11. Herunder fremgår det tydeligt, at bredden af forbindelsesstykket F i henhold til opfindelsen er væsentlig mindre end den tilsvarende dimension for ledningen L.In FIG. 4, it is further apparent that, as previously described with reference to the other figures, the connection piece F is passed between connection points respectively on a resilient tongue T of the rocker coupler and on the current conductor S1, which is connected to the conductor end N of the conductor 11. clearly, the width of the connector F according to the invention is substantially smaller than the corresponding dimension of the conduit L.
