More Information
Summary:This invention relates to a rolling electrical contact assembly which is very similar to an anti-friction bearing. The contact has an inner and outer race made of a conductive material. A set of conductive rollers roll around in the space between the races. A cage (insulating) keeps the rollers in proper spaced relationship. The outer race is stationary and is composed of segments having V-shaped spaces between the segments and is connected to an electrical cable, and the inner race which rotates on a shaft is connected by a cable carried by the shaft to a suitable current destination. The segments of the outer race are spring loaded to improve the contact conductivity between the rollers and the inner and outer races.
