Abstract

A device for transmitting current between two terminals of a cassette (K) between which at least one ribbon cable is arranged that extends in turns. The cassette includes a fixed stator and a rotatable rotor between which the ribbon cable is positioned. One of the two terminals is movable relative to the other. The ribbon cable at its ends is located in the area of the terminals. It is brought out of the cassette at the terminals for the connection of continuing cables (17). At least two plate-shaped contact carriers (18, 19) are mounted to the outside of the stator of the cassette. The conductors of the ribbon cable on the one hand and the conductors of a continuing cable on the other hand can be connected to the contact carriers. The contact carriers are connected with one another by elastic snap-in elements to form a unit.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zur Stromübertragung zwischen zwei Endstellen, zwischen denen mindestens eine in einer Kassette untergebrachte, in Windungen verlaufende Flachbandleitung mit mindestens zwei elektrischen Leitern angeordnet ist, deren Länge wesentlich größer als der Abstand der beiden Endstellen voneinander ist, bei welcher die Kassette aus einem feststehenden Stator und einem drehbaren Rotor besteht, zwischen denen die Flachbandleitung angeordnet ist, bei welcher mindestens eine der beiden Endstellen relativ zu der anderen bewegbar ist und bei welcher die Flachbandleitung an ihren im Bereich der Endstellen liegenden Enden aus der Kassette herausgeführt ist (EP 0 834 968 A2).The invention relates to a device for power transmission between two Terminals, between which at least one is housed in a cassette, in Flat ribbon cable with at least two electrical conductors is arranged, the length of which is substantially greater than the distance between the two end points is from each other, in which the cassette from a fixed stator and a rotatable rotor, between which the ribbon cable is arranged, at which at least one of the two end positions is movable relative to the other and in which the ribbon cable at its ends in the area of the end points is led out of the cassette (EP 0 834 968 A2).

Derartige Vorrichtungen werden beispielsweise bei der Stromzuführung für einen Airbag in einem Kraftfahrzeug verwendet. Sie wird bei dieser Anwendung in das Lenkrad des Kraftfahrzeugs eingebaut. Ein wesentliches Problem dabei und bei entsprechenden Vorrichtungen allgemein ist die Stromübertragung zwischen feststehenden und beweglichen Teilen derselben. Dieses Problem tritt bei allen Geräten auf, bei denen zwei relativ zueinander bewegbare Endstellen vorhanden sind, von denen in den meisten Fällen eine als Festpunkt ausgebildet ist. Die für solche Fälle üblichen Schleifkontakte bzw. Schleifringe sind einem Verschleiß unterworfen und insbesondere bei niedrigen Stromstärken wegen der schwankenden Übergangswiderstände nachteilig.Such devices are used, for example, in the power supply for an airbag used in a motor vehicle. You will in this application in the steering wheel of the Motor vehicle installed. A major problem with this and with corresponding Devices in general is the transmission of electricity between fixed and moving parts of the same. This problem occurs on all devices that have two there are relatively movable end points, most of which Cases one is designed as a fixed point. The usual sliding contacts for such cases or slip rings are subject to wear and especially at low Amperages disadvantageous because of the fluctuating contact resistance.

Die bekannte Vorrichtung nach dem DE 91 07 726 U1 kommt ohne derartige schleifende Kontakte aus. Die Stromübertragung erfolgt bei dieser Vorrichtung durch eine zwischen zwei Endstellen nach Art eines Federhauses einer Uhr gewickelte Flachleiter-Bandleitung - im folgenden kurz "FL-BL" genannt. Bei einer relativen Drehbewegung der beiden durch die FL-BL verbundenen Endstellen "atmet" die in einer Kassette untergebrachte FL-BL wie die Feder einer Uhr. Die Windungen der FL-BL werden in der einen Drehrichtung auf einen kleineren Durchmesser zusammengezogen. Sie gehen in der anderen Drehrichtung wieder auf einen größeren Durchmesser auf. Die Enden der FL-BL sind abgeknickt und aus der Kassette herausgeführt. Sie dienen zum Anschluß derselben an eine Stromquelle einerseits und an Steuerelemente andererseits. Die mechanisch empfindlichen Leiter der FL-BL und die Knickstelle sind jeweils mechanisch durch einen dieselbe umgebenden Schutzkörper geschützt. Probleme können sich bei dieser Vorrichtung ergeben, wenn die FL-BL mit einer erhöhten Anzahl von Leitern breiter wird. Ein entsprechend langer bzw. breiter Raum zum Durchführen der vom Schutzkörper umgebenen FL-BL steht meist nicht zur Verfügung.The known device according to DE 91 07 726 U1 comes without such grinding contacts. The power transmission takes place in this device by one wound between two end points like a barrel of a watch Flat conductor ribbon cable - hereinafter referred to as "FL-BL". With a relative Rotational movement of the two end points connected by the FL-BL "breathes" in one Cassette housed FL-BL like the feather of a watch. The turns of the FL-BL are contracted to a smaller diameter in one direction of rotation. They go back to a larger diameter in the other direction of rotation. The The ends of the FL-BL are bent and led out of the cassette. They serve for Connection of the same to a power source on the one hand and to control elements on the other. The mechanically sensitive conductors of the FL-BL and the kink are each mechanically protected by a protective body surrounding it. issues can result in this device if the FL-BL with an increased number of ladders gets wider. A correspondingly long or wide space to carry out the FL-BL surrounded by the protective body is usually not available.

Bei der bekannten Vorrichtung nach der eingangs erwähnten EP 0 834 968 A2 sind die Enden der FL-BL ebenfalls abgeknickt und aus der Kassette herausgeführt. An jedem Ende ist ein die FL-BL und deren Knickstelle umgebender Schutzkörper angebracht, der ebenso wie die FL-BL in mindestens zwei parallel zueinander verlaufende, flache Teilkörper aufgeteilt ist, die in montiertem Zustand mit ihren Flachseiten aneinander liegen. Dadurch bleibt der Schutzkörper als mechanischer Schutz des abgeknickten Teils der FI-BL erhalten. Für die Montage der Kassette an bzw. in Teilen eines Lenkrades eines Kraftfahrzeugs kann die Öffnung zur Durchführung des Schutzkörpers in ihrer Länge bzw. Breite unverändert bleiben. Sie muß nur geringfügig aufgeweitet werden, damit ein aus zwei oder mehr Teilkörpern bestehender Schutzkörper hindurchgeführt werden kann. Die zumindest zweiteiligen Schutzkörper sind getrennt herzustellende zusätzliche Elemente.In the known device according to EP 0 834 968 A2 mentioned at the outset, these are The ends of the FL-BL are also bent and led out of the cassette. On everyone At the end is a protective body surrounding the FL-BL and its kink, the just like the FL-BL in at least two flat ones running parallel to each other Partial body is divided, the assembled with their flat sides together lie. As a result, the protective body remains as mechanical protection of the bent part received the FI-BL. For mounting the cassette on or in parts of a steering wheel Motor vehicle can the opening for carrying the protective body in its length or width remain unchanged. It only has to be expanded slightly so that a protective bodies consisting of two or more partial bodies are passed through can. The at least two-part protective bodies are additional to be manufactured separately Elements.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs geschilderte Vorrichtung so weiterzubilden, daß sie einfacher hergestellt und montiert werden kann.The invention has for its object the device described above to further develop that it can be manufactured and assembled more easily.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst,

  • daß am Stator der Kassette außen mindestens zwei plattenförmige Kontaktträger angebracht sind, die einen Freiraum zur Aufnahme von gegeneinander isolierten elektrischen Kontakten umschließen, an welche einerseits die Leiter der FL-BL und andererseits die Leiter von mindestens einer weiterführenden elektrischen Leitung anschließbar sind, und
  • daß die Kontaktträger sowie gegebenenfalls weitere Kontaktträger huckepackartig durch federnd einrastende Elemente zu einer Einheit verbunden sind.
According to the invention, this object is achieved by
  • that at least two plate-shaped contact carriers are attached to the outside of the stator of the cassette, which enclose a free space for receiving mutually insulated electrical contacts, to which on the one hand the conductors of the FL-BL and on the other hand the conductors of at least one further electrical line can be connected, and
  • that the contact carriers and possibly further contact carriers are piggyback-connected by resiliently engaging elements to form a unit.

Diese Vorrichtung ist weitgehend unabhängig von der Anzahl der Leiter der FL-BL einsetzbar. Die Leiter der FL-BL sind bei fertiggestellter Vorrichtung an die Kontakte von mindestens einem Kontaktträger der Kassette angeschlossen. Wenn beispielsweise zwei mit Kontakten ausgerüstete Kontaktträger eingesetzt werden, können die Enden einer FL-BL entsprechend der Anzahl von Kontakten der beiden unterschiedlichen Kontaktträger aufgeteilt werden. Es können dann aber auch zwei FL-BL eingesetzt werden, deren Leiter getrennt voneinander mit den Kontakten unterschiedlicher Kontaktträger verbunden werden können. Das wird zweckmäßig bereits bei der Konfektionierung der FL-BL vor der Festlegung der Kontaktträger an der Kassette durchgeführt. Die Leiter der FL-BL (eine oder mehr als eine) können mit den Kontakten der Kontaktträger beispielsweise durch Löten oder Schweißen elektrisch leitend verbunden werden. Es kann dann ein erster Kontaktträger mit der Kassette direkt oder mit einem an derselben angebrachten Halter verbunden werden. Alle weiteren Kontaktträger können beispielsweise huckepackartig am ersten bzw. einem jeweils schon montierten Kontaktträger mittels federnd einrastender Elemente angeschnappt werden. Die jeweilige Einheit von Kontaktträgern kann auf einer Stirnfläche der Kassette angebracht sein oder auch an einer Umfangsfläche derselben. Ein wesentlicher Vorteil dieser Vorrichtung besteht auch darin, daß unabhängig von der Anzahl der Leiter der FL-BL und von weiterführenden Leitungen für die Kassette mit Kontaktträgern grundsätzlich der gleiche Aufbau verwendet werden kann. Dabei muß jeweils nur mindestens einer der Kontaktträger zum Anschluß der jeweiligen Leiter mit elektrischen Kontakten ausgerüstet sein. Der zweite oder auch weitere Kontaktträger brauchen nur dann Kontakte zu tragen, wenn eine entsprechend höhere Anzahl von Leitern angeschlossen werden soll. Es werden dementsprechend jeweils nur so viele, relativ teure Kontakte in den Kontaktträgern eingesetzt, wie sie zum Anschließen von Leitern benötigt werden. Es ist also auch möglich, Kontaktträger mit in eine Einheit einzubauen, die keine Kontakte haben. Das äußere Erscheinungsbild der Kassetten ist dann stets gleichbleibend, egal wieviel Leiter ihre FL-BL hat.This device is largely independent of the number of conductors of the FL-BL used. When the device is finished, the conductors of the FL-BL are connected to the contacts of at least one contact carrier of the cassette connected. For example, if two equipped with contacts, the ends of a FL-BL according to the number of contacts of the two different ones Contact carriers can be divided. But then two FL-BL can also be used be, whose conductors are separate from each other with the contacts different Contact carrier can be connected. That is useful already at the The FL-BL is assembled before the contact carrier is attached to the cassette carried out. The conductors of the FL-BL (one or more than one) can use the contacts the contact carrier is electrically conductive, for example by soldering or welding get connected. It can then be a first contact carrier with the cassette directly or be connected to a holder attached to the same. All further Contact carriers can, for example, piggyback on the first or one in each case mounted contact carrier can be snapped by means of resiliently engaging elements. The respective unit of contact carriers can be on an end face of the cassette be attached or on a peripheral surface thereof. A major advantage this device also consists in the fact that regardless of the number of conductors FL-BL and of further lines for the cassette with contact carriers basically the same structure can be used. It only has to at least one of the contact carriers for connecting the respective conductors with electrical Contacts. The second or other contact carrier only need then wear contacts when there is a correspondingly higher number of conductors to be connected. Accordingly, there are only so many, relatively expensive Contacts used in the contact carriers, as required for connecting conductors become. It is also possible to install contact carriers in a unit that does not Have contacts. The outer appearance of the cassettes is then always constant, no matter how many conductors your FL-BL has.

Stellvertretend für beide Ausführungsformen werden im folgenden flache Leiter berücksichtigt. Die Flachbandleitung wird der Einfachheit halber weiter als "FL-BL" bezeichnet. Die Anzahl der in der Kassette in einer oder mehr als einer FL-BL vorhandenen Leiter ist an sich beliebig und nur durch das Fassungsvermögen der Kassette begrenzt. Die Leiter der FL-BL werden auf jeden Fall zu ihrem Anschluß mit den Kontakten mindestens eines Kontaktträgers verbunden.The ribbon cable in the cassette can be made with round or flat conductors be equipped. The following are representative of both embodiments flat ladder considered. For convenience, the ribbon cable is wider than Inscribed "FL-BL". The number of times in the cassette in one or more than one FL-BL existing ladder is arbitrary in itself and only by the capacity of the Cassette limited. The conductors of the FL-BL will definitely be connected to the Connected at least one contact carrier contacts.

    In der folgenden Beschreibung wird für das zu erläuternde Ausführungsbeispiel davon ausgegangen, daß in der FL-BL so viel Leiter vorhanden sind, daß zwei mit elektrischen Kontakten bestückte Kontaktträger eingesetzt werden. Zweckmäßigerweise sind die Kontaktträger gleich aufgebaut, mit einer gleichen Anzahl von Kontakten. Diese müssen in der fertigen Kassette nicht alle belegt sein, wenn beispielsweise weniger Leiter in der FL-BL vorhanden sind als Kontakte zur Verfügung stehen. Es können aber auch Kontaktträger mit einer unterschiedlichen Anzahl von Kontakten verwendet werden. Wenn beispielsweise zwei getrennte FL-BL in der Kassette vorhanden sind, dann können deren Leiter getrennt voneinander jeweils an einen der Kontaktträger angeschlossen werden. Bei nur einer FL-BL wird dieselbe an ihren Enden in zwei getrennte Teile aufgeteilt.In the following description, the embodiment to be explained will be explained assumed that there are so many conductors in the FL-BL that two with electrical Contacts equipped contact carriers are used. These are expediently Contact carrier constructed the same way, with an equal number of contacts. These must not all of them are occupied in the finished cassette if, for example, fewer conductors in the FL-BL are available as contacts are available. But it can also Contact carriers with a different number of contacts can be used. For example, if there are two separate FL-BLs in the cassette, then you can whose conductors are each connected separately to one of the contact carriers become. If there is only one FL-BL, it ends up in two separate parts divided up.

    In Fig. 1 sind schematisch zwei beispielsweise kreisförmig ausgebildete Wandungen 1 und 2 einer Kassette K dargestellt, die beispielsweise zur Stromversorgung für einen Airbag in das Lenkrad eines Kraftfahrzeugs eingebaut werden kann. Zur Stromversorgung einer Elektronik 3 ist dieselbe über eine FL-BL 4 an eine Spannungsquelle 5 des Kraftfahrzeugs angeschlossen. Die Spannngsquelle 5 ist über eine elektrische Leitung 6 mit einer als Festpunkt ausgeführten Endstelle 7 verbunden. Die Elektronik 3 ist über eine elektrische Leitung 8 an eine Endstelle 9 angeschlossen, die in Richtung des Doppelpfeiles 10 bewegbar ist. Zwischen den beiden Endstellen 7 und 9 ist die FL-BL 4 angebracht.1 schematically shows two, for example, circular walls 1 and 2 a cassette K shown, for example for the power supply for one Airbag can be installed in the steering wheel of a motor vehicle. to Power supply for electronics 3 is the same via an FL-BL 4 to one Voltage source 5 of the motor vehicle connected. The voltage source 5 is over an electrical line 6 is connected to a terminal 7 designed as a fixed point. The electronics 3 is connected via an electrical line 8 to a terminal 9 is movable in the direction of the double arrow 10. Between the two end points 7 and 9 the FL-BL 4 is attached.

    Die FL-BL 4 kann gemäß Fig. 1 zwischen den beiden Endstellen 7 und 9 in mehreren Windungen angeordnet sein, nach Art eines Federhauses von Uhren. Obwohl die Anzahl der Umdrehungen eines Lenkrades auf etwa sechs Umdrehungen begrenzt ist, sollen wesentlich mehr als sechs Windungen für die FL-BL 4 vorgesehen sein. Die Drehbewegung der Endstelle 9 macht sich dann für eine einzelne Windung der FL-BL 4 nicht wesentlich bemerkbar. Es wird lediglich der Durchmesser des aus allen Windungen der FL-BL 4 bestehenden Wickels verkleinert bzw. vergrößert.The FL-BL 4 can according to FIG. 1 between the two end points 7 and 9 in several Coils can be arranged in the manner of a barrel of clocks. Although the number the turns of a steering wheel is limited to about six turns Much more than six turns can be provided for the FL-BL 4. The Rotary movement of the end point 9 then makes for a single turn of the FL-BL 4 not significantly noticeable. It will just be the diameter of all the turns of the FL-BL 4 existing coil is reduced or enlarged.

    Die FL-BL 4 kann gemäß Fig. 2 in der Kassette K auch in Windungen angeordnet sein, die in einen äußeren Wickelbereich 11 und einen inneren Wickelbereich 12 unterteilt sind. Die beiden Wickelbereiche 11 und 12 sind durch Klammern gekennzeichnet. Sie können jeweils zwei bis drei Windungen haben. In den beiden Wickelbereichen 11 und 12 haben die Windungen der FL-BL 4 entgegengesetzte Wickelrichtungen. Die Wickelbereiche 11 und 12 sind durch eine etwa U-förmig ausgeführte Umkehrstelle 13 miteinander verbunden.
