Device for electrically conductive connection between two parts of motion mechanism, has liquid metal, former part that is moved relative to later part, where former part has wheel rotating at axis

摘要

The device (1) has a liquid metal (7), a part (3) that is moved relative to another part (5). The former part has a wheel (11) rotating at an axis (9) for exercise of a rolling motion of the later part. An electrical connection is formed between the rotating wheel and an element of the former part is non moving around the axis. The rotating wheel is formed as an electrical conductor. The gallium or indium connections or an eutectic made of metal components gallium, indium and tin. An independent claim is also included for a linear motion mechanism, particularly a linear motor, which has a device with a part.
