Description

Die Erfindung bezieht sich auf eine Anordnung gemäß dem Oberbegriff des Patentanspruchs 1. Eine solche Anordnung geht aus der US 2002/112320 A1 hervor.The invention relates to an arrangement according to the preamble of claim 1. Such an arrangement is apparent from the US 2002/112320 A1 out.

Zum Anschluß von elektrischen Stromverbrauchern eines Kraftfahrzeugs, bei welchem es sich um einen Personenkraftwagen (PKW) oder um einen Lastkraftwagen handeln kann, an eine in demselben vorhandene Batterie als Spannungsquelle, werden in bekannter Technik sogenannte Kabelbäume eingesetzt. In solchen Kabelbäumen ist eine mehr oder weniger große Anzahl von elektrischen Leitungen zu einer Einheit zusammengefaßt. Je nach Größe der zu überbrückenden Entfernungen zwischen Batterie und/oder Steuergeräten einerseits und Stromverbrauchern andererseits können die Leitungen unterschiedliche Längen haben. Je mehr Stromverbraucher anzuschließen sind, desto aufwendiger werden die Kabelbäume mit entsprechend aufwendiger Montage. Der Einfachheit halber wird im folgenden statt des Wortes "Kraftfahrzeug" die Abkürzung "PKW" verwendet.To connect electrical power consumers of a motor vehicle, which may be a passenger car or a truck, to a battery in the same as a voltage source, so-called harnesses are used in a known technique. In such harnesses a more or less large number of electrical lines is combined into one unit. Depending on the size of the distances to be bridged between battery and / or control devices on the one hand and power consumers on the other hand, the lines may have different lengths. The more power consumers are connected, the more expensive the harnesses are with correspondingly complex installation. For the sake of simplicity, the abbreviation "PKW" will be used in the following instead of the word "motor vehicle".

In einem PKW vorhandene Stromverbraucher sind beispielsweise die Glühlampen in Scheinwerfern und Rückleuchten, Motoren zur Spiegelverstellung, zum Öffnen und Schließen von Fenstern und zur Sitzverstellung, Sitzheizungen, eine Lenkradheizung, Beleuchtungen des Armaturenbrettes und der Kennzeichen, Sensoren und Steuergeräte. Solange die Stromverbraucher an oder in der Karosserie eines PKWs montiert sind, ergeben sich keine besonderen Probleme. Das ist anders, wenn die Stromverbraucher sich an oder in einem beweglichen Teil des PKWs befinden. "Bewegliche Teile" sind dabei alle Türen des PKWs, ganz besonders aber eine als Heckklappe ausgeführte Tür. Der Einfachheit halber wird im folgenden statt der Worte "bewegliches Teil" das Wort "Tür" verwendet. Jede Tür ist um eine Drehachse schwenkbar mit der Karosserie des PKWs verbunden. Die zu den an oder in der Tür angebrachten Stromverbrauchern führenden Leitungen werden bei jeder Bewegung der Tür hin- und hergebogen. Sie werden also dauernd mechanisch belastet und können daher leicht beschädigt werden.In a car existing power consumers are, for example, the bulbs in headlights and taillights, motors for mirror adjustment, opening and closing windows and seat adjustment, seat heaters, a steering wheel heating, lighting the dashboard and the license plates, sensors and control units. As long as the power consumers are mounted on or in the body of a car, there are no special problems. This is different if the power consumers are located on or in a moving part of the car. "Moving parts" are all doors of the car, but especially a designed as a tailgate door. For the sake of simplicity, the word "door" will be used hereinafter instead of the words "movable part". Each door is pivotally connected about an axis of rotation with the body of the car. The leads leading to the power consumers mounted on or in the door are bent back and forth with each movement of the door. So they are constantly mechanically loaded and therefore can be easily damaged.

Aus der JP 08048146 A geht eine Anordnung zur Stromversorgung von in einem Kraftfahrzeug angebrachten Stromverbrauchern hervor, bei welcher eine der Anzahl der Stromverbraucher entsprechende Anzahl von elektrischen Leitungen in zwei miteinander verbundenen Einheiten zusammengefaßt ist, die einerseits an eine im Kraftfahrzeug befindliche Spannungsquelle und andererseits an die Stromverbraucher angeschlossen sind. Die Stromverbraucher sind sowohl an der Karosserie des Kraftfahrzeugs als auch an einem beweglichen Teil desselben angebracht, der um eine Drehachse schwenkbar mit der Karosserie verbunden ist. Außerhalb der Drehachse ist eine in Windungen verlaufende oder als Bifilarwickel ausgebildete elektrische Leitung mit Kontaktelementen angebracht, die einer Schwenkbewegung des beweglichen Teils folgen kann und an deren Kontaktelemente einerseits die mit der Spannungsquelle verbundenen Leitungen und andererseits die zu den Stromverbrauchern des beweglichen Teils führenden Leitungen elektrisch leitend angeschlossen sind.From the JP 08048146 A shows an arrangement for the power supply of mounted in a motor vehicle power consumers, in which one of the number of power consumers corresponding number of electrical lines in two interconnected units is summarized, which are connected on the one hand to a voltage source located in the motor vehicle and on the other hand to the power consumers. The power consumers are mounted on both the body of the motor vehicle and on a movable part thereof, which is pivotally connected to the body about a rotation axis. Outside the axis of rotation is a winding running or bifilar winding formed electrical line with contact elements, which can follow a pivotal movement of the movable part and on the contact elements on the one hand connected to the voltage source lines and on the other hand electrically conductive to the power consumers of the movable part lines are connected.

Bei der bekannten Anordnung nach der eingangs erwähnten US 2002/112320 A1 ist der Kabelbaum ebenfalls in zwei Teile aufgeteilt, von denen einer an der Karosserie eines PKWs und der andere an einer Tür desselben angebracht ist. Innerhalb eines Scharniers dieser Anordnung ist ein Kabelbaum vorhanden, der im Bereich der Drehachse des Scharniers innerhalb eines Rohres parallel zu derselben verläuft. Die Leitungen dieses Kabelbaums sind an beiden Enden an als Stifte ausgeführte Kontaktelemente von Steckverbindern angeschlossen, die im Scharnier selbst befestigt sind. Auf die Kontaktelemente können Gegenkontakte aufgesteckt werden, die an den Enden der beiden Teile des Kabelbaums angebracht sind.In the known arrangement according to the above-mentioned US 2002/112320 A1 the wiring harness is also divided into two parts, one of which is attached to the body of a car and the other to a door thereof. Within a hinge of this arrangement, a wire harness is provided which extends in the region of the axis of rotation of the hinge within a tube parallel to the same. The leads of this harness are connected at both ends to pins made of pins contact elements of connectors which are mounted in the hinge itself. On the contact elements mating contacts can be attached, which are attached to the ends of the two parts of the wiring harness.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs geschilderte Anordnung so zu gestalten, daß die beiden Einheiten des Kabelbaums auf einfache Weise miteinander verbunden werden können.The invention has for its object to make the above-described arrangement so that the two units of the wiring harness can be easily connected to each other.

Diese Aufgabe wird entsprechend den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst.This object is achieved according to the characterizing features of claim 1.

In dieser Anordnung sind die Leitungen des Kabelbaums eines PKWs im Schwenkbereich zwischen Karosserie und Tür in zwei Teile aufgetrennt, die jeder an die Kontaktelemente des dort befindlichen Kontaktträgers angeschlossen und dadurch miteinander verbunden sind. Der Kabelbaum bzw. seine Leitungen werden durch die Schwenkbewegung der Tür also nicht mehr mechanisch belastet. Jedes Kontaktelement ist als Spirale mit mindestens einer Windung ausgeführt. Die Spirale stellt sicher, daß die Enden eines Kontaktelements ohne bleibende Verformung desselben um Winkel bis etwa 150° hin und her bewegt werden können, wenn die Tür vollständig geöffnet und wieder geschlossen wird. Der Kontaktträger ist dadurch so aufgebaut, daß er bzw. seine Kontaktelemente die Schwenkbewegung der Tür mitmachen kann bzw. können. Er ist für diesen speziellen Einsatzzweck konzipiert, so daß er seine Funktion als drehbarer bzw. schwenkbarer Verbinder auf Dauer erfüllen kann. Dabei bleibt die Lage der Anschlußstellen bzw. Enden der Kontaktelemente, mit denen die Leitungen der beiden Teile des Kabelbaums verbunden sind, in jeder Stellung der Tür unverändert, so daß die Leitungen auch an diesen Anschlußstellen durch die Schwenkbewegungen der Tür nicht mechanisch beansprucht werden. Durch die bei dieser Anordnung gegebene Aufteilung des Kabelbaums kann die jeweilige Tür vorverkabelt werden, so daß die in der Tür befindlichen und mit den entsprechenden Stromverbrauchern verbundenen Leitungen nach Montage der Tür an der Karosserie des PKWs nur noch an den Kontaktelementen der ebenfalls vormontierbaren Kontaktträger angeschlossen zu werden brauchen.In this arrangement, the lines of the wiring harness of a car in the swivel range between the body and door are separated into two parts, which are each connected to the contact elements of the contact carrier located there and thereby connected to each other. The wiring harness or its lines are therefore no longer mechanically stressed by the pivoting movement of the door. Each contact element is designed as a spiral with at least one turn. The spiral ensures that the ends of a contact element can be reciprocated without permanent deformation of the same by angles up to about 150 °, when the door is fully opened and closed again. The contact carrier is thereby constructed so that he or his contact elements can join the pivotal movement of the door or can. It is designed for this special purpose, so that it can fulfill its function as a rotatable or swiveling connector permanently. In this case, the position of the connection points or ends of the contact elements, with which the lines of the two parts of the wiring harness are connected, unchanged in any position of the door, so that the lines are not mechanically stressed at these connection points by the pivoting movements of the door. By given in this arrangement division of the wiring harness, the respective door can be vorverkabelt, so that the door located in the door and connected to the corresponding power consumers connected after mounting the door to the body of the car only to the contact elements of the likewise preassembled contact carrier will need.

In Fig. 1 ist ein PKW 1 schematisch in einer Seitenansicht dargestellt, der in diesem Ausführungsbeispiel mit vier Türen 2 und einer als Heckklappe ausgeführten Tür 3 ausgerüstet ist. Teile und Ausrüstungen des PKWs 1, die zu seinem Betrieb erforderlich sind, werden hier nicht weiter erläutert. Sie sind grundsätzlich bekannt. Ebenso ist es bekannt, daß Stromverbraucher, wie beispielsweise Scheinwerfer und Rückleuchten, über sogenannte Kabelbäume mit Strom versorgt werden. Auch der Aufbau eines Kabelbaums, in dem eine der Anzahl der Stromverbraucher entsprechende Anzahl von elektrischen Leitungen zu einer Einheit zusammengefaßt ist, wird daher nicht beschrieben.In Fig. 1 is a car 1 is shown schematically in a side view, which is equipped in this embodiment with four doors 2 and a designed as a tailgate door 3. Parts and equipment of the car 1, which are necessary for its operation, will not be further explained here. They are known in principle. It is also known that power consumers, such as lights and taillights, are supplied via so-called harnesses with electricity. Also, the structure of a wire harness, in which one of the number of power consumers corresponding number of electrical lines is combined to form a unit is therefore not described.

Die Tür 3 ist schwenkbar mit der Karosserie 4 des PKWs 1 verbunden, und zwar beispielsweise über in einer Drehachse 5 vorhandene Scharniere. Sie kann aus der in Fig. 1 dargestellten Schließstellung in gestrichelt eingezeichnete Offenstellungen um die Drehachse 5 geschwenkt werden. Ein an oder in der Tür 3 angeordneter Stromverbraucher 6 ist zu seiner Stromversorgung über einen mit elektrischen Leitungen ausgerüsteten Kabelbaum mit der Batterie des PKWs 1 verbindbar. Diese Verbindung muß ungestört erhalten bleiben, auch wenn die Tür 3 sehr oft in Richtung des Doppelpfeils 7 um die Drehachse 5 geschwenkt wird.The door 3 is pivotally connected to the body 4 of the car 1, for example via existing in a rotation axis 5 hinges. She can get out of the Fig. 1 shown closed position in dashed open positions are pivoted about the axis of rotation 5. A arranged on or in the door 3 power consumers 6 is connected to its power supply via a cable harness equipped with electrical lines with the battery of the car 1. This connection must remain undisturbed, even if the door 3 is very often pivoted in the direction of the double arrow 7 about the axis of rotation 5.

Der Kabelbaum ist bei der Anordnung nach einer Ausführungsform der Erfindung in dem hier interessierenden Bereich in zwei Einheiten K1 und K2 aufgeteilt. Die Einheit K1 des Kabelbaums ist an der Karosserie 4 des PKWs befestigt. Sie enthält eine Anzahl von elektrischen Leitungen, die an einem Ende beispielsweise mit der Batterie des PKWs verbunden sind. Die Einheit K2 des Kabelbaums ist in der Tür 3 montiert. Sie hat mit Vorzug eine Anzahl von elektrischen Leitungen, welche der Anzahl der in oder an der Tür 3 vorhandenen Stromverbraucher entspricht. Eine dieser Leitungen ist an den Stromverbraucher 6 angeschlossen.In the arrangement according to one embodiment of the invention, the cable harness is divided into two units K1 and K2 in the area of interest here. The unit K1 of the wiring harness is fixed to the body 4 of the car. It contains a number of electrical lines, which are connected at one end, for example, with the battery of the car. The unit K2 of the wiring harness is mounted in the door 3. It has with preference a number of electrical lines, which corresponds to the number of existing in or on the door 3 power consumers. One of these lines is connected to the power consumer 6.

Zwischen den beiden Einheiten K1 und K2 des Kabelbaums ist mindestens ein Kontaktträger 8 mit Kontaktelementen 9 angeordnet, an welche die Leitungen der Einheit K1 des Kabelbaums einerseits und dessen Einheit K2 andererseits angeschlossen sind. Der Kontaktträger 8 bzw. seine Kontaktelemente 9 sind derart aufgebaut, daß er bzw. sie eine Schwenkbewegung der Tür 3 auf Dauer unbeschadet mitmachen kann bzw. können. Dazu ist der Kontaktträger 8 in der Drehachse 5 montiert, und zwar mit Vorteil an einem der dort befindlichen Scharniere.Between the two units K1 and K2 of the wiring harness at least one contact carrier 8 is arranged with contact elements 9, to which the lines of the unit K1 of the wiring harness on the one hand and the unit K2 on the other are connected. The contact carrier 8 and its contact elements 9 are constructed such that he or she can join a pivoting movement of the door 3 in the long run without damage or can. For this purpose, the contact carrier 8 is mounted in the axis of rotation 5, with advantage on one of the hinges located there.

Jedes Kontaktelement 9 ist gemäß Fig. 6 als Spirale mit mindestens einer Windung ausgeführt. Die Spirale stellt sicher, daß die Enden eines Kontaktelements 9 ohne bleibende Verformung desselben um Winkel bis etwa 150° hin und her bewegt werden können, wenn die Tür 3 vollständig geöffnet und wieder geschlossen wird. Je mehr Windungen die Spirale hat, desto günstiger wird dieser Effekt. In Fig. 6 sind drei Windungen dargestellt. Die Anzahl der Windungen ist aber wegen der möglichst kleinen Abmessungen des Kontaktträgers 8 begrenzt.Each contact element 9 is according to Fig. 6 designed as a spiral with at least one turn. The spiral ensures that the ends of a contact element 9 can be reciprocated without permanent deformation of the same by angles up to about 150 °, when the door 3 is fully opened and closed again. The more turns the spiral has, the cheaper this effect will be. In Fig. 6 three turns are shown. However, the number of turns is limited because of the smallest possible dimensions of the contact carrier 8.

Der Kontaktträger 8 besteht mit Vorteil aus einem mechanisch stabilen Kunststoff, wie beispielsweise Polybuthylenterephthalat (PBT) oder Polycarbonat (PC). Er ist mit einer Anzahl von gegeneinander isolierten Kontaktelementen 9 bestückt. Es sollen mindestens zwei Kontaktelemente 9 sein. Der Kontaktträger 8 ist in den dargestellten Ausführungsbeispielen aus mehreren aus Isoliermaterial bestehenden Scheiben 10 aufgebaut, die axial nebeneinander liegend beispielsweise auf einer Achse 11 angebracht sind. Je eine Scheibe 10 trägt vorzugsweise ein Kontaktelement 9.The contact carrier 8 is advantageously made of a mechanically stable plastic, such as polybutylene terephthalate (PBT) or polycarbonate (PC). He is equipped with a number of mutually insulated contact elements 9. There should be at least two contact elements 9. The contact carrier 8 is constructed in the illustrated embodiments of several consisting of insulating discs 10, which are mounted axially adjacent to each other, for example, on an axis 11. Depending on a disc 10 preferably carries a contact element. 9

Die Kontaktelemente 9 bestehen aus einem gut leitenden Metall, wie beispielsweise Edelstahl, Bronze, Messing, Kupfer oder einer Kupferlegierung. Sie sind drahtförmig ausgebildet und haben federnde Eigenschaften. Nach Montage des Kontaktträgers 8 weisen die Kontaktelemente 9 einerseits in Richtung der Einheit K1 des Kabelbaums und andererseits in Richtung der Einheit K2 desselben.The contact elements 9 are made of a highly conductive metal, such as stainless steel, bronze, brass, copper or a copper alloy. They are wire-shaped and have resilient properties. After mounting the contact carrier 8, the contact elements 9 on the one hand in the direction of the unit K1 of the wiring harness and on the other hand in the direction of the unit K2 thereof.

Um eine Bewegung der Kontaktelemente 9 im Kontaktträger 8 zu ermöglichen, können die Scheiben 10 gemäß Fig. 3 zumindest in einem der Bereiche, an denen die Enden der Kontaktelemente 9 aus dem Kontaktträger 8 herausragen, mit in Umfangsrichtung verlaufenden Schlitzen 12 versehen sein. Die Scheiben 10 können aber auch selbst in Umfangsrichtung um die Achse 11 drehbar im Kontaktträger 8 angeordnet sein. Schlitze 12 sind bei dieser Ausführungsform nicht erforderlich. Die Enden der Kontaktelemente 9 ragen gemäß den Fig. 3 und 4 auf zwei unterschiedlichen Seiten so weit aus dem Kontaktträger 8 heraus, daß sie zur elektrischen Kontaktierung zur Verfügung stehen.In order to enable a movement of the contact elements 9 in the contact carrier 8, the discs 10 according to Fig. 3 at least in one of the areas where the ends of the contact elements 9 protrude from the contact carrier 8, be provided with extending slots 12 in the circumferential direction. The discs 10 may also be arranged in the circumferential direction around the axis 11 rotatably in the contact carrier 8. Slits 12 are not required in this embodiment. The ends of the contact elements 9 project according to the 3 and 4 on two different sides so far out of the contact carrier 8 that they are available for electrical contact.

Dazu sind die Enden der Kontaktelemente 9 als Steckerstifte geformt bzw. ausgebildet.For this purpose, the ends of the contact elements 9 are formed or formed as plug pins.

Zum Aufstecken von Gegensteckern auf die Kontaktelemente 9, die an den Leitungen der Einheiten K1 und K2 des Kabelbaums angebracht sind, können die aus dem Kontaktträger 8 herausragenden Enden der Kontaktelemente 9 in bekannter Technik von einem Steckergehäuse 13 bzw. 14 umgeben sein, das mit zum Kontaktträger 8 gehört und einen feuchtigkeitsdichten Abschluß für die Kontaktelemente 9 garantiert. Die Steckergehäuse 13 und 14 weisen mit Vorteil auch Elemente auf, wie Vorsprünge oder Vertiefungen, durch welche die Gegenstecker der anzuschließenden Leitungen des Kabelbaums zugentlastet festzulegen sind.For attaching mating connectors to the contact elements 9, which are attached to the lines of the units K1 and K2 of the wiring harness, the protruding from the contact carrier 8 ends of the contact elements 9 may be surrounded in a known technique of a connector housing 13 and 14, which with the Contact carrier 8 belongs and guarantees a moisture-tight seal for the contact elements 9. The plug housings 13 and 14 advantageously also have elements, such as projections or recesses, by means of which the mating plugs of the lines to be connected of the cable harness are to be secured with strain relief.

Zur Fertigstellung der elektrisch leitenden Verbindungen zwischen den Leitungen der Einheiten K1 und K2 des Kabelbaums wird zunächst der Kontaktträger 8 in der Drehachse 5 des PKWs montiert. Danach werden die Gegenstecker der Leitungen des Kabelbaums auf die Kontaktelemente 9 aufgesteckt. Dabei können mit Vorteil beide Einheiten K1 und K2 des Kabelbaums bereits vormontiert sein, so daß zur Herstellung der elektrisch leitenden Verbindungen nur noch die Gegenstecker in die Steckergehäuse 13 bzw. 14 eingesteckt zu werden brauchen. Sie sind dann in den Steckergehäusen 13 und 14 zugentlastet festgelegt. Die Möglichkeit der Vormontage bzw. Vorverkabelung wirkt sich besonders vorteilhaft für die Tür 3 aus.To complete the electrically conductive connections between the lines of the units K1 and K2 of the wiring harness, the contact carrier 8 is first mounted in the axis of rotation 5 of the car. Thereafter, the mating connector of the wires of the wiring harness are attached to the contact elements 9. In this case, both units K1 and K2 of the wiring harness can be preassembled with advantage, so that need only be plugged into the connector housing 13 and 14 for the preparation of electrically conductive connections only the mating connector. They are then set in the plug housings 13 and 14 strain relieved. The possibility of pre-assembly or pre-wiring has a particularly advantageous effect for the door 3.

Die Anordnung nach der Erfindung ist im Vorangehenden für die Tür 3 (Heckklappe) des PKWs erläutert. Sie ist analog dazu auch bei jeder anderen Tür des PKWs einsetzbar.The arrangement according to the invention is explained in the foregoing for the door 3 (tailgate) of the car. It can be used analogously to any other door of the car.
