Abstract

A connector for current conduction for bridging interruptions in conductance between component parts which are rotatable relative to one another, more especially between steering wheel and steering column, comprising a housing having a stator which includes a conductor output (2) and is mountable on the steering column, and a rotor (3), which is rotatable with the steering wheel and is also provided with a conductor output (4), said component parts defining an annular chamber which surrounds the rotor and serves to accommodate a conductor strip which loops around the rotor in a plurality of windings and terminates in the conductor outputs (2, 4). A plurality of resilient plates (8) are disposed in a radial position in the stator the conductor strip (6), or its windings, being held loosely against the rotor (3) by means of said resilient plates. Two inwardly curved resilient projection members (9) are disposed on the circumference of the housing so that they lie radially opposite each other in identical directions, such resilient projection members applying pressure to the outer winding of the conductor strip (6). <IMAGE>

Description

Die Erfindung geht aus von einem Stromleitungsverbinder gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a power line connector according to the Preamble of claim 1.

Ein Stromleitungsverbinder dieser Art ist beispielsweise aus der US-A-4 722 690 bekannt geworden. Sie werden insbesondere zur Herstel­ lung einer elektrischen Verbindung zwischen einer Stromquelle und der in der Lenkradschüssel angeordneten Gassack-Aufprall-Schutzeinrichtung von Kraftfahrzeugen eingesetzt. Hierbei weist das im Gehäuseraum angeordnete Leiterband eine solche Länge auf, daß sie dem beidseitig etwa drei Umdrehungen betragenden Lenkradausschlag zu folgen vermag, wobei sich die Feder während des Lenkradausschlages aus einer mittleren Lage in der einen Richtung bis zur Anlage an dem stationären Gehäuse nach außen aufweitet und in der anderen Richtung bis zur Anlage an dem Rotor nach innen zusammenzieht.A power line connector of this type is, for example, from the US-A-4,722,690. In particular, they become a manufacturer an electrical connection between a power source and the Airbag impact protection device arranged in the steering wheel bowl used by motor vehicles. This points in the housing room Arranged conductor strip on such a length that it on both sides is able to follow a steering wheel deflection of approximately three revolutions, where the spring during the steering wheel deflection from a middle Position in one direction up to the contact with the stationary housing expands outward and in the other direction to the plant on the The rotor contracts inwards.

Die bekannten Stromleitungsverbinder haben sich in der Praxis im wesentlichen gut bewährt, es wird jedoch als ein Nachteil angesehen, daß das in dem Gehäuse geführte Leiterband einerseits bei der normalen Lenkradbewegung Kratzgeräusche und andererseits bei plötzlichen starken Erschütterungen - etwa in Kurven oder bei Fahren auf unebenem Gelände - starke Klappergeräusche abgeben, die vorwiegend durch das Aufeinander­ schlagen der Windungen des Leiterbandes aneinander verursacht werden.The known power line connectors have in practice well proven, but is considered a disadvantage that the conductor strip guided in the housing on the one hand in the normal Steering wheel movement scratching noises and on the other hand when suddenly strong Shocks - such as in curves or when driving on uneven terrain -  emit strong rattling noises, mainly due to the collision beating of the turns of the conductor tape against each other are caused.

Der vorliegenden Erfindung liegt als Aufgabe die Schaffung eines Stromleitungsverbinders zugrunde, mit dessen Hilfe auf eine einfache Weise die Geräuschentwicklung verhindert werden kann. Diese Aufgabe wird mit einem Stromleitungsverbinder mit den im Patentanspruch 1 wie­ dergegebenen Merkmalen gelöst.The present invention has for its object to provide a Power line connector based, with the help of a simple Way the noise can be prevented. This task is with a power line connector with the in claim 1 as the given features solved.

Durch die Erfindung ist ein Stromleitungsverbinder geschaffen, bei dem die Geräuschentwicklung weitgehend dadurch verhindert ist, daß das Leiterband bzw. dessen Windungen unter leichter Spannung gegen den Deckel gehalten und damit an der Ausführung freier Schwingbewegungen weitgehend gehindert ist, so daß das Entstehen von Klappergeräuschen weitgehend verhindert ist und allenfalls in Extremsituationen befürchtet werden muß. Hierbei hat sich überraschender Weise gezeigt, daß ungeachtet der engen Führung des Leiterbandes mit seinen Kanten auf den metallischen Zungen eine Beeinträchtigung des Leiterbandes nicht zu befürchten ist.The invention provides a power line connector, at which is largely prevented by the fact that the noise Conductor tape or its turns under slight tension against the Cover held and thus on the execution of free swinging movements is largely prevented, so that the development of rattling noises is largely prevented and at most in extreme situations must be feared. Here it has surprisingly been shown that regardless of the tight guidance of the conductor tape with its edges on the metallic tongues do not adversely affect the conductor strip fear.

Der in der Zeichnung wiedergegebene Stromleitungsverbinder zur Überbrückung von Leiterunterbrechungen zwischen einer fahrzeugfesten Lenksäule und einem auf der Lenksäule drehbaren Lenkrad besteht aus dem an der Lenksäule befestigbaren Stator 1 mit Leiterabgang 2 sowie dem mit dem Lenkrad drehbaren Rotor 3, der ebenfalls mit einem Leiterabgang 4 versehen ist. Stator 1 und Rotor 3 bilden ein einen Ringraum 5 umschließendes Gehäuse, das der Aufnahme eines den Rotor in mehreren Windungen umschlingenden, in den Leiterabgängen 2, 4 endenden Leiter­ bandes 6 dient. Hierbei können die Leiterabgänge von einem Kontaktstift gebildet sein, an dem die Enden der Wickelfeder befestigt sind, es kann jedoch auch das Leiterband 6 selbst - etwa durch Umspritzen - durch den Rotor bzw. die Statorwandung sein, so das das Leiterband selbst die Leiterabgänge bildet.
Fig. 4 is a section B-B through FIG. 3
The power line connector shown in the drawing for bridging conductor interruptions between a steering column fixed to the vehicle and a steering wheel which can be rotated on the steering column consists of the stator 1 with a conductor outlet 2 which can be fastened to the steering column and the rotor 3 which can be rotated with the steering wheel and which is also provided with a conductor outlet 4 . Stator 1 and rotor 3 form a housing 5 which encloses an annular space and serves to accommodate a conductor band 6 which wraps around the rotor in several turns and ends in the conductor outlets 2 , 4 . Here, the conductor outlets can be formed by a contact pin to which the ends of the clock spring are fastened, but it can also be the conductor strip 6 itself - for example by extrusion coating - through the rotor or the stator wall, so that the conductor strip itself forms the conductor outlets.

In dem im Beispielsfalle gleichzeitig den Boden des Ringraumes 5 begrenzenden Boden des Stators 1 sind in radialer Lage mehrere Feder­ plättchen 8 angeordnet, mit deren Hilfe das Leiterband 6 bzw. seine Windungen lose gegen die im Beispielsfalle von dem Rotor gebildeten oberen Begrenzungsfläche des Ringraumes 5 gehalten werden. Es sind weiterhin am Umfang des Stators 1 radial gegenüberliegend gleichsinnig zwei nach innen gebogene Federzungen 9 angeordnet, die sich auf der äußeren Windung des Leiterbandes 6 abstützen und dieses damit in einander entgegengesetzter Radialrichtung beaufschlagen, so daß das Leiterband an der freien Ausführung von radialen Bewegungen gehindert ist. Das Entstehen von Klappergeräuschen ist auf diese Weise weiterhin stark behindert.In the example, at the same time delimiting the bottom of the annular space 5, the bottom of the stator 1 , a plurality of spring plates 8 are arranged in a radial position, with the aid of which the conductor strip 6 or its windings are held loosely against the upper boundary surface of the annular space 5 formed by the rotor in the example become. There are further arranged on the circumference of the stator 1 radially opposite the same direction two inwardly bent spring tongues 9, which are supported on the outer turn of the conductor strip 6 and thus apply this in opposite radial direction so that the conductor strip is prevented from free running radial movements is. The creation of rattling noises is still severely hindered in this way.
