Description

Die Erfindung betrifft eine Schalteranordnung mit einem an einer Grundplatte verschieblichen Schleifkontakt, dessen zugehörige Schleiferbahn sich in einer ersten Ebene erstreckt und mit vom Schleifkontakt kontaktierbaren Kontaktstücken in einer Zweiten Ebene gemäß dem Oberbegriff des Anspruches 1.The invention relates to a switch arrangement with a sliding contact that is displaceable on a base plate, the associated sliding path of which extends in a first level and with contact pieces that can be contacted by the sliding contact in a second level.

Eine solche Schalteranordnung ist aus der FR-A-1 362 279 bekannt. Dabei sind die Kontaktstücke eines Stufendrehschalters auf zwei Kontaktträger aufgeteilt, die sich in ungleichen, zur Verdrehrichtung parallelen Ebenen gegenüberstehen. Ein zwischen den parallelen Ebenen angeordneter Schleifkontakt kontaktiert gleichzeitig Kontaktstücke aus beiden Kontaktstück-Ebenen.Such a switch arrangement is known from FR-A-1 362 279. The contact pieces of a multi-stage rotary switch are divided into two contact carriers, which face each other in different planes parallel to the direction of rotation. A sliding contact arranged between the parallel planes simultaneously contacts contact pieces from both contact piece levels.

Derartige Schalteranordnungen sind beispielsweise zur Betätigung der Klimaanlage in Kraftfahrzeugen vorgesehen. Sollen mit einer solchen Schalteranordnung hohe Ströme geschaltet werden, ist einerseits eine hohe Zuverlässigkeit der Kontaktgabe erwünscht. Andererseits sollen, da ein Verschleiß nicht auszuschließen ist, dann wenigstens die verschlissenen Schalterteile leicht austauschbar sein.Switch arrangements of this type are provided, for example, for actuating the air conditioning system in motor vehicles. If high currents are to be switched with such a switch arrangement, a high level of reliability of the contact is desirable. On the other hand, since wear cannot be ruled out, then at least the worn switch parts should be easily replaceable.

Aufgabe der Erfindung ist es, eine Schalteranordnung der eingangs genannten Art vorzuschlagen, bei der eine zuverlässige Kontaktgabe und eine leichte Austauschbarkeit gegeben ist.The object of the invention is to propose a switch arrangement of the type mentioned in the introduction, in which reliable contacting and easy interchangeability is provided.

Nach der Erfindung ist obige Aufgabe dadurch gelöst, daß die Schleiferbahn und die Kontaktstücke an einem Träger gehalten sind, daß der Schleifkontakt über die Schleiferbahn und die Kontaktstücke hinaus verschieblich ist, und daß der Träger neben dem Führungskörper in eine Ausnehmung der Grundplatte lösbar eingesteckt ist und mit Anschlußelementen ausgestattet ist.According to the invention the above object is achieved in that the slider track and the contact pieces are held on a carrier, that the sliding contact is displaceable beyond the slider track and the contact pieces, and that the carrier is detachably inserted next to the guide body in a recess in the base plate and is equipped with connecting elements.

Die Anschlußelemente des Trägers, z.B. Messerkontakte, kontaktieren mit Flachkontakten eines Steckers und stehen somit in Verbindung mit den weiterführenden Anschlußkabeln. Der Stecker ist in eine Ausnehmung des Gehäuses rastend und lösbar eingesteckt. Der Träger und der Stecker können unabhängig voneinander in ihre Ausnehmung im Gehäuse eingesteckt und daraus entfernt werden, ohne daß das jeweilige Gegenstück aus seiner Rastposition bewegt wird. Beim Einstecken des Trägers in seine Ausnehmung kann der selbständig gehaltene Stecker nicht weggedrückt werden und beim Entfernen nicht mitgezogen werden. Beim Einstecken des Steckers in seine Ausnehmung kann der selbständig gehaltene Träger nicht weggedrückt werden und beim Abziehen nicht mitgezogen werden.The connection elements of the carrier, e.g. Knife contacts, make contact with the flat contacts of a plug and are therefore in connection with the connecting cables. The plug is latched and detachably inserted into a recess in the housing. The carrier and the plug can be inserted independently of one another into their recess in the housing and removed therefrom without the respective counterpart being moved out of its latching position. When the carrier is inserted into its recess, the independently held plug cannot be pushed away and cannot be pulled along when it is removed. When the plug is inserted into its recess, the independently held carrier cannot be pushed away and cannot be pulled along when it is removed.

Der Schleifkontakt ist zur Kontaktierung der einzelnen Kontaktstücke zwischen diesen und der Schleiferbahn verschieblich. Er liegt dabei fest an der Schleiferbahn einerseits und an dem betreffenden Kontaktstück andererseits auf. Bei Verschleiß der Kontaktstücke wird der Schleifkontakt über die Schleiferbahn und die Kontaktstücke hinaus verschoben, so daß diese frei sind. Es läßt sich dann der Träger von der Grundplatte abziehen und austauschen.The sliding contact is slidable for contacting the individual contact pieces between them and the sliding track. It lies firmly on the grinding track on the one hand and on the contact piece in question on the other. If the contact pieces wear, the sliding contact is moved beyond the sliding track and the contact pieces so that they are free. The carrier can then be removed from the base plate and exchanged.

Die Schalteranordnung kann als Schiebeschalter bei geradliniger Verschiebung des Schleifkontakts oder als Drehschalter bei kreisförmiger Verschieblichkeit des Schleifkontakts ausgebildet sein.The switch arrangement can be designed as a slide switch when the sliding contact is moved in a straight line or as a rotary switch when the sliding contact is movable in a circular manner.

Ein Drehschalter weist eine Grundplatte 1 auf, an der ein um eine Drehachse 2 drehbarer Drehkörper 3 gelagert ist. Am Drehkörper 3 ist eine Blattfeder 4 befestigt, an deren freien Ende ein Schleifkontakt 5 angeordnet ist. Der Schleifkontakt 5 weist einen S-förmig gebogenen Schleifkopf 6 auf.A rotary switch has a base plate 1 on which a rotary body 3 rotatable about an axis of rotation 2 is mounted. On the rotating body 3, a leaf spring 4 is attached, at the free end of which a sliding contact 5 is arranged. The sliding contact 5 has an S-shaped curved grinding head 6.

An der Grundplatte 1 ist eine Ausnehmung 7 vorgesehen, in die ein Träger 8 eingeschnappt ist. Er sitzt dabei auf einem Steg 9 der Grundplatte 1 auf. Zwischen der Ausnehmung 7 und dem Träger 8 ist eine leicht lösbare Rastverbindung 10 vorgesehen. Beim Lösen der Rastverbindung 10 läßt sich der Träger 8 in Richtung des Pfeiles P nach vorn aus der Ausnehmung 7 herausziehen.A recess 7 is provided on the base plate 1, into which a carrier 8 is snapped. He sits on a web 9 of the base plate 1. An easily releasable latching connection 10 is provided between the recess 7 and the carrier 8. When the locking connection 10 is released, the carrier 8 can be pulled out of the recess 7 in the direction of the arrow P to the front.

Am Träger 8 ist eine Schleiferbahn 11 befestigt, die in einer zur Drehachse 2 senkrechten ersten Ebene 12 verläuft und sich auf einem Teil kreis um die Drehachse 2 erstreckt. An der Schleiferbahn 11 ist als Anschlußelement ein Messerkontakt 13 ausgebildet, der an der der Schleiferbahn 11 abgewandten Seite des Trägers 8 diesen überragt und durch den Steg 9 hindurch den Flachkontakt 22 des Steckers 24 kontaktiert.On the carrier 8, a grinder track 11 is fastened, which runs in a first plane 12 perpendicular to the axis of rotation 2 and extends in a circle around the axis of rotation 2. A knife contact 13 is formed on the grinder track 11 as a connecting element, which protrudes above the carrier 8 on the side facing away from the grinder track 11 and contacts the flat contact 22 of the plug 24 through the web 9.

Am Träger 8 sind mehrere Kontaktstücke 14 befestigt, die sich in einer von der ersten Ebene 12 beabstandeten zweiten Ebene 15 erstrecken, wobei die beiden Ebenen 12 und 15 parallelliegen. Die Kontaktstücke 14 liegen unter der Schleiferbahn 11. Jedes Kontaktstück 14 weist einen Messerkontakt 16 auf, der den Träger 8 an der den Kontaktstücken 14 abgewandten Seite überragt und unterhalb des Steges 9 den Flachkontakt 23 des Steckers 24 kontaktiert.A plurality of contact pieces 14 are fastened to the carrier 8 and extend in a second plane 15 spaced apart from the first plane 12, the two planes 12 and 15 being parallel. The contact pieces 14 lie under the wiper track 11. Each contact piece 14 has a knife contact 16 which projects beyond the carrier 8 on the side facing away from the contact pieces 14 and contacts the flat contact 23 of the plug 24 below the web 9.

Die Grundplatte hat eine weitere Ausnehmung 28, in die ein Stecker 24 eingeschnappt ist. Das Einführen des Steckers in seine Ausnehmung wird ebenfalls durch den Steg 9 begrenzt. Beim Lösen der Rastverbindung 25 zwischen Ausnehmung 28 und Stecker 24 läßt sich der Stecker 24 in entgegengesetzter Richtung des Pfeiles P nach hinten herausziehen.The base plate has a further recess 28 into which a plug 24 is snapped. The insertion of the plug into its recess is also limited by the web 9. When releasing the latching connection 25 between the recess 28 and the plug 24, the plug 24 can be pulled out in the opposite direction of the arrow P to the rear.

Im Stecker 24 kontaktieren ortsfest gehaltene Flachkontakte 22, 23 die jeweiligen, aus dem Träger 8 herausragenden und durch den Steg 9 hindurchgeführten Messerkontakte 13, 16.Flat contacts 22, 23 held in a fixed position in the plug 24 contact the respective knife contacts 13, 16 which protrude from the carrier 8 and pass through the web 9.

Die Flachkontakte 22, 23 sind an ihrem, der Einsteckseite der Messerkontakte 13, 16 abgewandten Ende mit Verbindungshülsen 29 ausgerüstet. Die Verbindungshülse 29 ist so gestaltet, daß ein Kabel 26 ortsfest gehalten wird und elektrisch verbindet.The flat contacts 22, 23 are equipped with connecting sleeves 29 on their end facing away from the insertion side of the knife contacts 13, 16. The connecting sleeve 29 is designed so that a cable 26 is held stationary and electrically connects.

Zwischen der Schleiferbahn 11 und den Kontaktstücken 14 steht der S-förmige Schleifkopf 6 (vgl. Figur 2 und 3). Mittels der Blattfeder 4 ist der S-förmige Schleifkopf 6 so vorgespannt, daß er mit seiner einen Biegung 17 an die Schleiferbahn 11 und mit seiner anderen Biegung 18 an das jeweilige Kontaktstück 14 angedrückt ist.The S-shaped grinding head 6 is located between the grinding track 11 and the contact pieces 14 (cf. FIGS. 2 and 3). By means of the leaf spring 4, the S-shaped grinding head 6 is prestressed in such a way that it is pressed with one bend 17 onto the sliding track 11 and with its other bend 18 against the respective contact piece 14.

Auf den Drehkörper 3 ist entgegen der Richtung des Pfeiles P ein Griffglied 27 aufsteckbar. Der Drehkörper 3 weist an seiner dem Griffglied abgewandten Seite eine Rastverzahnung 19 auf, in die ein Federelement 20 eingreift. Das Zusammenwirken von Rastverzahnung 19 und Federelement 20 ist derart, daß der Schleifkopf 6 das jeweilige Kontaktstück 14 in der angestrebten Arbeitsposition kontaktiert, indem nach Beendigung der äußeren Einwirkung über das Griffglied 27 der Schleifkopf 6 durch die Wirkung des Federelementes 20 solange verschoben wird, bis diese eine Rastposition in der Rastverzahnung 19 einnimmt.On the rotary body 3, a handle member 27 can be plugged against the direction of arrow P. The rotating body 3 has on its side facing away from the grip member a locking toothing 19, in which a spring element 20 engages. The interaction of locking toothing 19 and spring element 20 is such that the grinding head 6 contacts the respective contact piece 14 in the desired working position by the grinding element 6 being displaced by the action of the spring element 20 after the external action has ended via the grip member 27 until the latter takes a locking position in the locking teeth 19.

Am Umfang des Drehkörpers 3 ist eine Führungsnut 21 angeordnet, in die ein nicht näher dargestellter Hebel zur Verstellung eines mittels des Drehkörpers 3 bedienbaren Aggregats eingreift. An die Flachkontakte 23 sind zu schaltende Aggregate angeschlossen.On the periphery of the rotating body 3, a guide groove 21 is arranged, into which a lever (not shown in more detail) engages to adjust an assembly which can be operated by means of the rotating body 3. Units to be switched are connected to the flat contacts 23.

Mittels des Drehkörpers 3 läßt sich der Schleifkopf 6 stufenweise von einem Kontaktstück 14 zum benachbarten Kontaktstück fortschalten. Es ist damit das jeweilige Kontaktstück 14 mit der Schleiferbahn 11 elektrisch verbunden. Durch die Einspannung des Schleifkopfes 6 zwischen der Schleiferbahn 11 und den Kontaktstücken 14 ist ein zuverlässiger Kontakt gegeben. Durch die beschriebene Rastung ist die Kontaktgabe im Hinblick auf das Schaltverhalten verbessert, da die Schaltpositionen am Griffglied 27 erkennbar sind.By means of the rotating body 3, the grinding head 6 can be stepped forward from one contact piece 14 to the adjacent contact piece. The respective contact piece 14 is thus electrically connected to the wiper track 11. The clamping of the grinding head 6 between the grinding track 11 and the contact pieces 14 ensures reliable contact. The latching described improves the contact with regard to the switching behavior, since the switching positions on the handle member 27 are recognizable.

Die Kontaktstücke 14 und die Schleiferbahn 11 bestehen vorzugsweise aus Kupfer. Der Schleifkontakt 5 besteht vorzugsweise aus weniger verschleißanfälliger Bronze. Tritt im Laufe der Zeit ein Verschleiß der Kontaktstücke 14 ein, dann läßt sich der gesamte Träger 8 leicht von vorn austauschen. Es wird hierfür der Drehkörper 3 so weit gedreht, daß der Schleifkopf 6 nicht mehr zwischen der Schleiferbahn 11 und den Kontaktstücken 14 steht. Anschließend wird die Rastverbindung 10 gelöst und der Träger 8 mit der Schleiferbahn 11 und den Kontaktstücken 14 nach vorn gezogen. Es lassen sich dann die Messerkontakte 13 und 16 von den jeweiligen Flachkontakten 22, 23 abziehen, die dann die Messerkontakte 13 und 16 eines neuen Trägers 8 aufnehmen. Schließlich wird der neue Träger 8 in die Ausnehmung 7 eingeschnappt. Der Schleifkopf 6 kann dann wieder zwischen die Kontaktstücke 14 und die Schleiferbahn 11 durch Drehen des Drehkörpers 3 eingeschoben werden.The contact pieces 14 and the slider track 11 are preferably made of copper. The sliding contact 5 is preferably made of less wear-prone bronze. If wear of the contact pieces 14 occurs in the course of time, the entire carrier 8 can easily be replaced from the front. For this purpose, the rotating body 3 is rotated so far that the grinding head 6 is no longer between the grinding track 11 and the contact pieces 14. Then the latching connection 10 is released and the carrier 8 with the sliding track 11 and the contact pieces 14 is pulled forward. Then the knife contacts 13 and 16 can be pulled off the respective flat contacts 22, 23, which then receive the knife contacts 13 and 16 of a new carrier 8. Finally, the new carrier 8 is snapped into the recess 7. The grinding head 6 can then be inserted again between the contact pieces 14 and the grinding track 11 by rotating the rotating body 3.

Nach Abziehen des Steckers 24 kann die Grundplatte 1 insgesamt aus ihrer Position entnommen und nach einer dann einfach zu vollziehenden Bearbeitung wieder angebracht und nach Aufstecken des Steckers 9 wieder in Betrieb genommen werden.After the plug 24 has been removed, the base plate 1 can be removed from its position as a whole and, after processing which is then easy to carry out, can be reattached and put back into operation after the plug 9 has been plugged in.

Mit der Erfindung ist es möglich geworden, nach entsprechender Anpassung auch andere elektrische Verschleißteile oder Elemente mit absehbarer Auswechselerfordernis auf einfache Weise frontseitig auszutauschen.With the invention, it has become possible to replace other electrical wear parts or elements with a foreseeable need for replacement in a simple manner from the front after appropriate adaptation.

Außerdem kann die Erfindung als trennbare elektrische Energieversorgung für frontseitig angeordnete elektrische Verbraucher vorteilhaft eingesetzt werden.In addition, the invention can advantageously be used as a separable electrical energy supply for electrical consumers arranged on the front.
