Abstract

Such multiple switches, as are used in particular as on-off and/or changeover switches for motor vehicles and the like, must have an adequate life with a high operating reliability, despite the high stresses and load to which they are subjected, for example as a result of a high switching frequency on the one hand and atmospheric influences, such as air humidity, dirt and the like, on the other hand, which adequate life can be achieved in practice only by as little contact erosion as possible. The development of noise during the switching process is a disturbing influence in many cases. This is avoided by the contact surfaces (6, 7) in such a multiple switch being constructed in a straight-line manner, by the contact jacket (3) of the contact roll (2) being capable of being brought into contact with at least two contact surfaces (6, 7) located side-by-side, and by the contact roll (2) being arranged such that it can be deflected in a sprung manner on a guide part (8) which is displaceable in a straight line in the switch housing (1) at right angles to the axis of the contact roll (2) and parallel to the contact surfaces (6, 7), and has bearing journals (9, 10), which project at the ends beyond the contact jacket (3) and by means of which it is guided in a linearly displaceable manner on at least one control track (4) which runs adjacent to the contact surfaces (6, 7) and has a ramp arrangement (5), in such a manner that, in the event of a displacement of the guide part (8) from one of the contact surfaces (6, 7), it lifts on one side. <IMAGE>

Description

Die Erfindung betrifft einen Mehrfachschalter, insbesondere Ein-, Aus- und/oder Umschalter für Kraftfahrzeuge und art­verwandte Anwendung, mit mindestens einer walzenförmigen Kontaktrolle, die unter Federdruck steht und deren Kontakt­mantel mittels Steuerbahnen und Rampenanordnungen von be­nachbarten Kontaktflächen abhebbar und mit diesen in Kon­taktberührung bringbar ist.The invention relates to a multiple switch, in particular on, off and / or changeover switch for motor vehicles and related applications, with at least one roller-shaped contact roller which is under spring pressure and whose contact jacket can be lifted from adjacent contact surfaces by means of control tracks and ramp arrangements and brought into contact with them .

Derartige Mehrfachschalter, wie sie insbesondere als Ein-, Aus- und/oder Umschalter bei Kraftfahrzeugen und derglei­chen eingesetzt werden, müssen trotz der hohen Beanspru­chungen und Belastungen, wie sie einerseits durch hohe Schalthäufigkeit, andererseits aber auch durch atmosphä­rische Einflüsse, wie Luftfeuchtigkeit, Verschmutzung und dergleichen, gegeben sind, bei hoher Betriebssicherheit eine ausreichende Lebensdauer haben, die praktisch nur durch einen möglichst geringen Kontaktabbrand erreicht werden kann. Störend sind vielfach auch Geräuschentwick­lungen beim Schaltvorgang.Such multiple switches, such as those used in particular as on, off and / or changeover switches in motor vehicles and the like, must be used in spite of the high stresses and strains such as that due to high switching frequency on the one hand but also due to atmospheric influences such as air humidity, pollution and the like, are given, with high operational reliability, have a sufficient lifespan that can practically only be achieved by as little contact erosion as possible. In many cases, noise is also disruptive during the switching process.

Der Erfindung liegt die Aufgabe zugrunde, einen Mehrfach­schalter nach dem Oberbegriff des Anspruches 1 so auszubil­den, daß dieser bei hoher Belastbarkeit und einer geringst­möglichen Geräuschentwicklung bei den einzelnen Schaltvor­gängen eine hohe Lebensdauer erreicht und den gestellten Anforderungen hinsichtlich eines geringst möglichen Kontakt­abbrandes genügt.The invention has for its object to form a multiple switch according to the preamble of claim 1 so that it achieves a long service life with high load capacity and the lowest possible noise during the individual switching operations and meets the requirements with regard to the lowest possible contact erosion.

Diese Aufgabe wird bei einem gattungsgemäßen Schalter gemäß der Erfindung dadurch gelöst, daß die Kontaktflächen gerad­linig ausgebildet sind, daß der Kontaktmantel der Kontakt­rolle mit mindestens zwei nebeneinanderliegenden Kontakt­flächen in Kontaktberührung bringbar ist, und daß die Kon­taktrolle an einem im Schaltergehäuse quer zur Achse der Kontaktrolle und parallel zu den Kontaktflächen geradlinig verschiebbaren Führungsteil federnd auslenkbar angeordnet ist und über den Kontaktmantel endseitig hinausragende Lagerzapfen aufweist, mit denen sie auf mindestens einer neben den Kontaktflächen verlaufenden Steuerbahn mit Ram­penanordnung derart linear verschiebbar geführt ist, daß sie bei einer Verschiebung des Führungsteiles von einer der Kontaktflächen einseitig abhebt.This object is achieved in a generic switch according to the invention in that the contact surfaces are linear, that the contact jacket of the contact roller can be brought into contact with at least two adjacent contact surfaces, and that the contact roller in a switch housing transverse to the axis of the contact roller and parallel to the contact surfaces linearly displaceable guide part is arranged to be resiliently deflectable and has end journals projecting beyond the contact jacket, with which it is linearly displaceably guided on at least one control path running alongside the contact surfaces with a ramp arrangement such that it is unilaterally displaced when the guide part is displaced from one of the contact surfaces takes off.

Der erfindungsgemäße Mehrfachschalter hat den Vorteil, daß die elektrisch leitende Verbindung zwischen Stromzuführung und Stromausgang durch ein rollendes Verbindungsteil, näm­lich eine Kontaktrolle, im Zusammenspiel mit einer oder mehreren Rampenanordnungen hergestellt wird. Im ausgeschal­teten Zustand des Schalters ist die Kontaktrolle mindestens einseitig mittels einer Rampe von der Kontaktfläche ge­trennt. Soll der Stromkreis geschlossen werden, bewegt das mechanische Betätigungsteil oder Führungsteil des Schalters die Kontaktrolle vorzugsweise über eine abgeschrägte Fläche der Rampe auf die Kontaktfläche und stellt eine elektrische Verbindung her. Falls der Einsatz von hochwertigem, damit kostspieligem Kontaktmaterial erforderlich oder zweckmäßig ist, kann dieses Kontaktmaterial entsprechend dem Stromfluß auf nur eine von mehreren Kontaktstellen beschränkt werden.The multiple switch according to the invention has the advantage that the electrically conductive connection between the power supply and the current output is established in cooperation with one or more ramp arrangements by means of a rolling connecting part, namely a contact roller. When the switch is switched off, the contact roller is separated from the contact surface at least on one side by means of a ramp. If the circuit is to be closed, the mechanical actuating part or guide part of the switch preferably moves the contact roller over a bevelled surface of the ramp onto the contact surface and provides an electrical one Connect. If the use of high-quality, and therefore expensive, contact material is necessary or expedient, this contact material can be limited to only one of a number of contact points in accordance with the current flow.

Besonders vorteilhaft für die Schalthäufigkeit und damit für die Lebensdauer eines solchen Schalters ist es ferner, daß die Kontaktgabe und die Kontaktunterbrechung stets an einer vorbestimmten Seite des rollenden Verbindungsteiles erfolgt. Entsprechend dem Stromfluß ist eventuell erfor­derliches hochwertiges Kontaktmaterial nur an einer Kon­taktfläche notwendig, wobei es besonders vorteilhaft ist, daß aufgrund von unterschiedlichen Durchmessern des Kon­taktmantels der Kontaktrolle und der nach aussen hervor­stehenden Lagerzapfen in Verbindung mit der jeweiligen Rampe an jeder der beiden Steuerbahnen erreicht wird, daß die Rampe nicht an der gleichen Stelle auf die Kontaktrolle abhebend oder absenkend einwirkt, an der die elektrisch leitende Verbindung hergestellt wird.It is also particularly advantageous for the switching frequency and thus for the service life of such a switch that the contacting and the contact interruption always take place on a predetermined side of the rolling connecting part. Depending on the current flow, any high-quality contact material that may be required is only required on one contact surface, it being particularly advantageous that, due to different diameters of the contact jacket and the outwardly protruding bearing journals in connection with the respective ramp on each of the two control tracks, this is achieved the ramp does not have a lifting or lowering effect on the contact roller at the same point at which the electrically conductive connection is made.

Im übrigen kann das rollende Verbindungsteil bzw. die Kon­taktrolle sowohl ein- als auch mehrstückig ausgeführt sein.Otherwise, the rolling connecting part or the contact roller can be designed in one piece or in several pieces.

Der Mehrfachschalter, der insbesondere als Ein-, Aus- und/­oder Umschalter für Kraftfahrzeuge und artverwandte Anwen­dung bestimmt ist, hat in einem Gehäuse 1 mindestens eine walzenförmige Kontaktrolle 2, die unter Federdruck steht und deren zylindrischer Kontaktmantel 3 mittels Steuerbah­nen 4 und Rampenanordnungen 5 von benachbarten Kontaktflä­chen 6, 7 abhebbar und mit diesen in Kontaktberührung bringbar ist.The multiple switch, which is intended in particular as an on, off and / or changeover switch for motor vehicles and related applications, has in a housing 1 at least one roller-shaped contact roller 2 which is under spring pressure and whose cylindrical contact jacket 3 by means of control tracks 4 and ramp arrangements 5 from adjacent contact surfaces 6, 7 can be lifted off and brought into contact with them.

Die Kontaktflächen 6, 7 des Schalters sind geradlinig aus­gebildet, und der Kontaktmantel 3 der Kontaktrolle 2 er­streckt sich über mindestens zwei nebeneinanderliegende Kontaktflächen 6, 7.The contact surfaces 6, 7 of the switch are straight, and the contact jacket 3 of the contact roller 2 extends over at least two adjacent contact surfaces 6, 7.

Die Kontaktrolle 2 ist an einem im Schaltergehäuse 1 quer zur Achse der Kontaktrolle 2 und parallel zu den Kontakt­flächen 6, 7 geradlinig verschiebbaren Führungsteil 8 fe­dernd auslenkbar angeordnet und weist über den Kontaktman­tel 3 endseitig hinausragende Lagerzapfen 9, 10 auf, die einen geringeren Durchmesser als der Kontaktmantel 3 haben.The contact roller 2 is arranged on a in the switch housing 1 transversely to the axis of the contact roller 2 and parallel to the contact surfaces 6, 7 linearly displaceable guide member 8 and deflects over the contact jacket 3 end projecting bearing pins 9, 10, which have a smaller diameter than that Have contact jacket 3.

Mit diesen endseitigen Lagerzapfen 9, 10 ist die Kontakt­rolle 2 auf mindestens einer neben den Kontaktflächen 6, 7 verlaufenden Steuerbahn 4 mit einer schrägen Rampenanord­nung 5 derart linear verschiebbar geführt, daß sie bei einer Verschiebung des Führungsteiles 8 nur von einer der Kontaktflächen 6, 7 einseitig abgehoben wird.With these end bearing journals 9, 10, the contact roller 2 is guided linearly displaceably on at least one control path 4 running alongside the contact surfaces 6, 7 with an inclined ramp arrangement 5 such that, when the guide part 8 is displaced, only one of the contact surfaces 6, 7 unilaterally is lifted off.

Wie in der Zeichnung weiterhin zu erkennen ist, weisen die beiderseits der beiden Kontaktflächen 6, 7 angeordneten Steuerbahnen 4 jeweils in Verschieberichtung des Führungs­teiles 8 gegeneinander versetzte Rampen 5a, 5b für die La­gerzapfen 9, 10 der Kontaktrolle 2 auf.As can also be seen in the drawing, the control tracks 4 arranged on both sides of the two contact surfaces 6, 7 each have ramps 5a, 5b offset relative to one another in the direction of displacement of the guide part 8 for the bearing journals 9, 10 of the contact roller 2.

In einer ersten Ausgangsstellung von Fig. 1 bis 3 liegt die Kontaktrolle 2 mit ihrem Kontaktmantel 3 auf beiden Kon­taktflächen 6, 7 gleichzeitig auf, um in einer zweiten Zwischenstellung nach geradliniger Verschiebung des Füh­rungsteiles 8 in Längsrichtung der Kontaktflächen 6, 7 zu­nächst durch eine (5a) der beiden Rampen 5a, 5b von der zugehörigen Kontaktfläche 6 schräg abgehoben zu werden und nach einer weiteren geradlinigen Verschiebung des Führungs­teiles 8 durch Auflaufen des gegenüberliegenden Lager­zapfens 10 auf die gegenüber der ersten Rampe 5a linear versetzte Rampe 5b der zweiten Steuerbahn 4 auch von der zweiten Kontaktfläche 7 abgehoben zu werden.In a first starting position from FIGS. 1 to 3, the contact roller 2 rests with its contact jacket 3 on both contact surfaces 6, 7 at the same time, in order in a second intermediate position after a straight displacement of the guide part 8 in the longitudinal direction of the contact surfaces 6, 7, first by a (5a ) of the two ramps 5a, 5b to be lifted obliquely from the associated contact surface 6 and after a further linear displacement of the guide part 8 by running the opposite bearing journal 10 onto the ramp 5b of the second control track 4, which is offset linearly with respect to the first ramp 5a, also from the second Contact surface 7 to be lifted off.

Wie in Fig. 1 bis 3 weiterhin zu erkennen ist, ist die Kon­taktrolle 2 mit ihren Lagerzapfen 9, 10 an dem Führungsteil 8 durch zwei Lagerstücke 11, 12 abgestützt, die quer zur Verschieberichtung des Führungsteiles 8 entgegen der Wir­kung von Schraubenfedern 13 unabhängig voneinander ver­schiebbar sind. Die Lagerstücke 11, 12 sind an dem Führungs­teil 8 in mehreckigen oder ovalen, vorzugsweise achteckig profilierten Führungsbuchsen 14 drehsicher auf und ab ver­ schiebbar geführt und weisen jeweils gabelförmig profilier­te Lagerstege 15 für die Lagerzapfen 9, 10 der Kontaktrolle 2 auf, die die Lagerzapfen 9, 10 beiderseits zwischen dem Kontaktmantel 3 der Kontaktrolle 2 und den außerhalb davon verlaufenden Steuerbahnen 4 und Rampenanordnungen 5 jeweils U-förmig übergreifen. Hierdurch wird eine besonders ruhige und genaue Führung der Lagerzapfen 9 der Kontaktrolle 2 quer zu den Steuerbahnen 4, den Rampenanordnungen 5 und auch gegenüber den Kontaktflächen 6, 7 erreicht ebenso wie eine einfache Montage beim Zusammenbau des Schalters.As can also be seen in FIGS. 1 to 3, the contact roller 2 with its journal 9, 10 is supported on the guide part 8 by two bearing pieces 11, 12 which can be displaced independently of one another transversely to the direction of displacement of the guide part 8 against the action of coil springs 13 are. The bearing pieces 11, 12 are on the guide part 8 in polygonal or oval, preferably octagonal profiled guide bushings 14 up and down ver slidably guided and each have fork-shaped profiled bearing webs 15 for the bearing journals 9, 10 of the contact roller 2, which overlap the bearing journals 9, 10 on both sides between the contact jacket 3 of the contact roller 2 and the control tracks 4 and ramp arrangements 5 running outside thereof in a U-shape. This achieves a particularly quiet and precise guidance of the journal 9 of the contact roller 2 transversely to the control tracks 4, the ramp arrangements 5 and also with respect to the contact surfaces 6, 7, as well as simple assembly when assembling the switch.

Die Kontaktflächen 6, 7 des Schalters sind an parallel zur Verschieberichtung des Führungsteiles 8 für die Kontakt­rolle 2 verlaufenden streifenförmigen Kontaktteilen 16, 17 mit Steckerzungen 18 ausgebildet, und das Führungsteil 8 ist im Schaltergehäuse 1 gegen den Druck einer Schrau­benfeder 19 längsverschiebbar geführt.The contact surfaces 6, 7 of the switch are formed on strip-shaped contact parts 16, 17 with plug tongues 18 running parallel to the direction of displacement of the guide part 8 for the contact roller 2, and the guide part 8 is longitudinally displaceably guided in the switch housing 1 against the pressure of a coil spring 19.

Das Führungsteil 8 hat außerdem einen aus dem Schalterge­häuse 1 hervorstehenden Betätigungsstift 20, der an dem Führungsteil 8 in unterschiedlichen Längsstellungen ein­rastbar angeordnet ist.The guide part 8 also has an actuating pin 20 protruding from the switch housing 1, which is arranged on the guide part 8 in different longitudinal positions.

In Fig. 6 ist schließlich eine Kontaktfläche 6 mit einer geriffelten Plattierung 6a gezeigt, die beispielsweise eine Silberplattierung sein kann und diagonal zur Betätigungs­richtung des Schalters bzw. zur Verschieberichtung der Kontaktrolle 2 angeordnet ist, um bei einem eventuell auf­tretenden Kontaktabbrand auf dieser Kontaktfläche den Kon­takteingriff an der Kontaktrolle 2 ebenfalls zu verlagern und damit bessere Kontakteigenschaften zu erzielen.6 finally shows a contact surface 6 with a corrugated plating 6a, which can be silver plating, for example, and is arranged diagonally to the actuating direction of the switch or to the direction of displacement of the contact roller 2, in order to initiate contact engagement on this contact surface in the event of contact erosion to shift the contact roller 2 and thus to achieve better contact properties.
