Abstract

The invention relates to a conductor arrangement (10) between an electric energy accumulator based on lithium ion battery cells and motor vehicle consumers connected by means of electric conductors (14). Said conductor arrangement is characterized in that the electric conductor (14) is accommodated in a cable duct (16) having rigid properties and a rectangular cross-section. The space between the electric conductor (14) and the cable duct (16) is filled with a fire-retardant filling material (12) that holds the electric conductor (14) in place.

Die Leiterführung, bestehend aus einem rechteckigen Kabelkanal, kann den elektrischen Leiter mittig aufnehmen. Dadurch ist gesichert, dass der elektrische Leiter keinen Schaden an seiner Isolation nimmt, der auftreten kann, wenn durch Fahrzeugerschütterungen ein mechanisches Scheuern an der Innenwand des Kabelkanals zugelassen würde. The conductor guide, consisting of a rectangular cable channel, can accommodate the electrical conductor in the middle. This ensures that the electrical conductor does not take any damage to its insulation, which can occur if a mechanical rubbing on the inner wall of the cable duct would be permitted by vehicle vibrations.

Ein Ausführungsbeispiel der Erfindung wird anhand einer Zeichnung erläutert. Dazu wird auf Figur 1 verwiesen. Es zeigt: An embodiment of the invention will be explained with reference to a drawing. Reference is made to FIG. It shows:
Figur 1 einen Querschnitt einer Leiterführung für ein Kraftfahrzeug. 1 shows a cross section of a conductor guide for a motor vehicle.
Figur 1 zeigt eine schematische Schnittansicht durch eine Leiterführung 10, die als Hochvoltpfad geeignet ist. Der mittig gelagerte und nach außen elektrisch isolierte Leiter 14 befindet sich in einem Kabelkanal 16, der hier in einem quadratischen Querschnitt vorliegt. Der Leiter 14 wird von einem Füllmaterial 12 umhüllt und damit in seiner etwa mittigen Lage im Kabelkanal 16 fixiert. Figure 1 shows a schematic sectional view through a conductor guide 10, which is suitable as a high-voltage path. The centrally mounted and outwardly electrically insulated conductor 14 is located in a cable channel 16, which is present here in a square cross-section. The conductor 14 is enveloped by a filling material 12 and thus fixed in its approximately central position in the cable channel 16.
Der Kabelkanal 16 kann aus einem Metall, wie etwa aus Stahlblech gefertigt sein. Das Stahlblech kann eine Dicke im Bereich von 0,1 bis 1 mm, bevorzugt 0,5 mm, aufweisen. In alternativer Ausführung besteht der Kabelkanal 16 aus Kunststoff, insbesondere aus einem hoch schmelzenden, schwer entflammbaren Kunststoff, wie etwa einem Polyamid. The cable duct 16 may be made of a metal such as sheet steel. The steel sheet may have a thickness in the range of 0.1 to 1 mm, preferably 0.5 mm. In an alternative embodiment, the cable channel 16 made of plastic, in particular of a high-melting, flame-retardant plastic, such as a polyamide.
