Contactless electrical energy transmission arrangement e.g. for transmission between circuit on vehicle body and on vehicle seat, uses data-transmission and power-transmission transformers

摘要

An arrangement for contactless transmission of electrical energy between a fixed vehicle part and a linear movable vehicle part has at least one transformer (1,2) with primary and secondary windings (3,6) positioned in separate pot-type cores (11,12), in which one pot-type core (11) is arranged on a fixed vehicle part and the other (12) is arranged on a movable vehicle part, the cores (11,12) together being conceived along sliding rails forming a closed circuit for the magnetic flux between the windings (3-6). One transformer (1) is used for data transmission and the other (2) for power transmission.
