Abstract
A string of earth boring drill pipe has telemetry features. Each section of the drill pipe has a box tool joint on one end and a pin tool joint on the other end, with an insulated wire segment extending through the section. A contact ring is connected to one end of the wire segment and mounted to one of the tool joints. The contact ring has an exposed side. An annular contact member is connected to the other end of the wire segment and has an exposed side for contacting the exposed side of the contact ring when making up with another section. The contact member is laterally flexible and is mounted in an insulating member that is subjected to internal pressure in the drill string for urging the contact member toward the contact ring.
