Abstract

The system has two coils (2) on separate cores (1) arranged along the direction of an axis. Both cores are in the form of half shells and are arranged so that they can be assembled into a form similar to a shell for the transfer of current. The coils fit inside each other when assembled together.

Description

Es ist bekannt, einen Strom induktiv zwischen zwei getrennten oder trennbaren Geräten oder Geräteteilen zu übertragen, indem zwei Spulen, die sich jeweils auf einem Pilz- oder I-Kern befinden, in Richtung einer Achse ausgerichtet werden, und an der einen Spule Stromimpulse (ggf. Wechselstrom) mit hohen Frequenzen angelegt werden, die nun nach dem Induktionsgesetz übertragen werden.It is known to inductively supply a current between two separate or separable devices or device parts transmitted by two coils, each on a mushroom or I core, in the direction of an axis be aligned, and on one coil current pulses (possibly alternating current) with high frequencies be created, which are now transferred according to the induction law.

Dabei entsteht jedoch aufgrund des starken Streufeldes bzw. der schlechten Übertragung des magnetischen Flusses ein hoher Verlust, eine starke Begrenzung der übertragbaren Leistung und eine Einschränkung der Einsatzmöglichkeiten.However, this is due to the strong stray field or poor magnetic transmission A high loss of flow, a strong limitation on the transferable power and a limitation of the Possible uses.

Der im Patentanspruch 1 angegebenen Erfindung liegen die Probleme des starken Streufeldes bzw. der schlechten Übertragung des magnetischen Flusses zugrunde.The invention specified in claim 1, the problems of the strong stray field or poor transmission of the magnetic flux.

Diese Probleme werden durch ein System mit den im Patentanspruch 1 genannten Eigenschaften gelöst.These problems are solved by a system with the properties mentioned in claim 1.

Eine vorteilhafte Ausgestaltung des Systems ist in den Ansprüchen 2 bis 8 angegeben. Diese ermöglichen eine weitere Reduzierung des Streufeldes bzw. eine Erhöhung des übertragenen magnetischen Flusses (Anspruch 2, 3, 4, 7 und 8), eine Reduzierung der durch die magnetischen Kräfte entstehenden Vibrationen (Anspruch 6 und 8), eine exakte Positionierung und Justierung der beiden Kerne (Anspruch 2 und 6) sowie ein Verhindern der Überhitzung einer Spule bzw. ein Kurzschließen eines Stromkreises beim Trennen der beiden Kerne (Anspruch 5).An advantageous embodiment of the system is specified in claims 2 to 8. These enable one further reduction of the stray field or an increase in the transmitted magnetic flux (claim 2, 3, 4, 7 and 8), a reduction in the vibrations caused by the magnetic forces (claim 6 and 8), an exact positioning and adjustment of the two cores (claims 2 and 6) and a prevention of Overheating of a coil or short-circuiting of a circuit when separating the two cores (claim 5).

Zwei Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt, und werden im Folgenden näher beschrieben.Two exemplary embodiments of the invention are shown in the drawing and are described in more detail below described.
