Electrical signal interconnection coupler

摘要

A conductor for transmitting an electrical signal from a signal generator on a rotating member to a signal detector on a relatively stationary member across the motion interface between the two members comprises at least one solid carbon graphite ring mounted coaxially between the two members and having a first annular surface in intimate contact with a mating conductive surface on the signal generator and having a second annular surface in intimate contact with a mating conductive surface on the stationary member that is electrically connected to the signal detector, said carbon graphite ring functioning as an electrical interconnection between the two members.
