Abstract

Die Erfindung betrifft einen Polverbinder für Batterien mit einem Stromleiter zwischen zwei endseitigen Kontaktstücken, wobei der Stromleiter aus elektrisch leitfähigem Kunststoff besteht.The invention relates to a pole connector for batteries with a conductor between two end-side contact pieces, wherein the conductor consists of electrically conductive plastic.

Description

Die Erfindung betrifft einen Polverbinder für Batterien mit einem Stromleiter zwischen zwei endseitigen Kontaktstücken.The The invention relates to a pole connector for batteries with a conductor between two end contact pieces.

Es ist bekannt, mehrere Batterien insbesondere von Kraftfahrzeugen und Flurförderzeugen miteinander dadurch elektrisch aneinander anzuschließen, dass die Endpole der Batterien durch Polverbinder miteinander verbunden werden. Hierbei weist jeder Polverbinder ein Kabel als Stromleiter auf, an dessen beiden Enden jeweils ein metallenes Kontaktstück befestigt ist. Das Kabel weist mehrere Litzen/Drähte aus Kupfer und/oder Aluminium auf, die von einem isolierenden Kunststoffmantel umgeben sind. Diese bekannte Konstruktion eines Polverbinders erfordert einen erheblichen Arbeitsaufwand mit mehreren Arbeitsgängen.It is known, several batteries, especially of motor vehicles and industrial trucks thereby electrically connecting to each other, that the end poles of the batteries connected by pole connector become. Here, each pole connector has a cable as a conductor on, attached at its two ends in each case a metal contact piece is. The cable has multiple strands / wires of copper and / or aluminum on, which are surrounded by an insulating plastic sheath. These known construction of a Polverbinders requires a considerable Workload with several operations.

Aufgabe der Erfindung ist es, die Herstellung eines Polverbinders wesentlich zu vereinfachen.task The invention is essential to the manufacture of a Polverbinders to simplify.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Stromleiter aus elektrisch leitfähigem Kunststoff besteht. Hierbei ist von Vorteil, wenn die zwei endseitigen Kontaktstücke auch aus elektrisch leitfähigem Kunststoff bestehen, so dass der Stromleiter mit seien zwei Kontaktstücken aus einem einzigen Teil aus leitfähigem Kunststoff ist.These Task is inventively characterized solved, that the current conductor consists of electrically conductive plastic. in this connection is advantageous if the two end contact pieces as well made of electrically conductive Plastic so that the conductor with two contact pieces are made a single part of conductive Plastic is.

Ein solcher Polverbinder kann besonders einfach insbesondere in einem einzigen Arbeitsgang hergestellt werden. Hierzu bietet sich das 2-Komponenten-Spritzverfahren an, mit dem der Kunststoff-Stromleiter mit seinen zwei Kontaktstücken und seiner isolierenden Kunststoff-Ummantelung in einem einzigen Fertigungsprozess hergestellt wird. Dies führt zu äußerst niedrigen Fertigungskosten und zu einem geringeren Gewicht.One Such pole connector can be particularly simple, especially in one single operation. This offers the 2-component injection molding process with which the plastic conductor with its two contact pieces and his insulating plastic sheath in a single manufacturing process will be produced. this leads to to extremely low Production costs and a lower weight.

Verschiedene vorteilhafte Ausführungen des leitfähigen Kunststoffs sind in den Unteransprüchen aufgeführt.Various advantageous embodiments of the conductive Plastic are listed in the subclaims.

Im Folgenden werden einige Ausführungsbeispiele von Polverbindern beschrieben.in the Following are some embodiments described by pole connectors.

Ein Polverbinder weist einen länglichen Stromleiter auf, an dessen beiden Enden elektrisch leitende Kontaktstücke befestigt sind, die der Befestigung an den Batterie-Endpolen dienen. Der Stromleiter ist über seine Länge von einem Isoliermantel aus nicht leitendem Kunststoff umgeben.One Pole connector has an elongated conductor on, attached to the two ends of electrically conductive contacts which serve the attachment to the battery end poles. The conductor is over his length surrounded by an insulating sheath of non-conductive plastic.

Hierbei bestehen der Stromleiter und seine zwei endseitigen Kontaktstücke aus einem leitfähigen Kunststoff. Im leitfähigen Kunststoff sind als leitfähiger Füllstoff metallische, elektrisch leitende Teilchen in Form von Fasern, Plättchen oder Kügelchen angeordnet. Hierbei können die Fasern, Plättchen oder Kügelchen metallisch beschichtet sein. Vorzugsweise ist das Metall eine Legierung aus Kupfer und Zinn.in this connection consist of the conductor and its two end-side contacts a conductive Plastic. In the conductive Plastic are considered more conductive filler metallic, electrically conductive particles in the form of fibers, platelets or Arranged beads. Here you can the fibers, platelets or globule be metallically coated. Preferably, the metal is an alloy made of copper and tin.

In einer weiteren Ausführung sind im leitfähigen Kunststoff als leitfähiger Füllstoff

  • – Nano-Röhrchen aus Kohlenstoff und/oder
  • – Kohlenstoff-Fasern und/oder
  • – leitfähig beschichte Mineralien oder Keramiken und/oder
  • – Anthrazitkohlenstaub und/oder
  • – Ruß angeordnet.
In a further embodiment are in the conductive plastic as a conductive filler
  • - Nano-tubes made of carbon and / or
  • - carbon fibers and / or
  • - Conductively coated minerals or ceramics and / or
  • - Anthracitkohlenstaub and / or
  • - Soot arranged.

Vorzugsweise wird ein Plastik/Metall Hybrid verwendet, bei dem herkömmliche Thermoplaste oder thermoplastische Elastomere das Matrixmaterial darstellen und metallische Fasern für die elektrische Leitfähigkeit sorgen. Beispielhaft für ein solches Material sind etwa 15 Gewichts-% thermoplastisches Material, 55 Gewichts-% Kupferfaser und 30 Gewichts-% eines niedrig schmelzenden Materials (z. B. Zinn). Dieses Material erreicht spezifische elektrische Leitfähigkeiten in der Größenordnung von 2 × 10^'5 S/m. Kohlenstoff Nano-Tubes als Füllmaterial haben aufgrund ihrer graphitischen Oberflächenstruktur eine hohe elektrische Leitfähigkeit, die der eines Metalls sehr nahe kommt. Wegen der hohen spezifischen Oberfläche wird nur ein geringer Füllgrad der Additive zur Einstellung der elektrischen Leitfähigkeit benötigt. Ein Verbinder aus Plastik/Nano-Tube Hybrid ist hierbei deutlich leichter als ein aus einem Plastik/Metall Hybrid bestehender.Preferably a plastic / metal hybrid is used in which conventional Thermoplastics or thermoplastic elastomers the matrix material represent and metallic fibers for electrical conductivity to care. Exemplary for such a material is about 15% by weight thermoplastic material, 55% by weight of copper fiber and 30% by weight of a low melting point Materials (eg tin). This material reaches specific electrical conductivities in the order of magnitude of 2 × 10 ^ 5 S / m. carbon Nano tubes have as filling material due to their graphitic surface structure a high electrical Conductivity, which is very close to that of a metal. Because of the high specific surface Only a small degree of filling is the Additive to adjust the electrical conductivity needed. A plastic / nano-tube connector Hybrid is much lighter than a plastic / metal one Hybrid existing.

Vorzugsweise wird der Polverbinder in einem einzigen Arbeitsgang im 2-Komponenten-Spritzverfahren hergestellt.Preferably The pole connector is produced in a single operation in a 2-component injection molding process produced.
