  • Multiple channel rotary electrical connector
    Patent number: 10060216
    Abstract: A multiple channel rotary electrical connector can include multiple first contacts which are radially spaced apart from each other, and multiple second contacts which electrically contact respective ones of the first contacts while there is relative rotation between the first and second contacts. The second contacts may be radially spaced apart from each other. A well tool can include one section which rotates relative to another section of the well tool, and a multiple channel rotary electrical connector which includes multiple annular-shaped contacts that rotate relative to each other. A method of operating a well tool in a subterranean well can include producing relative rotation between sections of the well tool, and communicating multiple channels of electrical signals between the sections while there is relative rotation between the sections. The communicating can include electrically contacting multiple annular-shaped contacts with each other.
