Abstract: A wired pipe system includes a wired pipe segment having a first end and a second end and a first coupler in the first end and a second coupler in the second end. The system also includes a transmission line disposed in the wired pipe segment between the first and second ends. The transmission line includes an inner conductor, an insulating material surrounding the inner conductor, an outer conductor surrounding the insulating material and the inner conductor for at least a portion of a length of the transmission line, the outer conductor being formed by deforming around the inner conductor a sheet of material into a substantially tubular member.

Abstract: A connector for use in connecting a communication element to a transmission line in a wired pipe segment includes a first female end adapted to surround and make electrical contact with a coupler connection that extends away from a communication element of the coupler; a second female end adapted to receive an inner conductor of a coaxial cable; and an inner connection element formed on an inner surface of the connector adapted to electrically connect the coupler connection and the inner conductor, the inner connection element formed such that it does not completely surround at least one of the inner conductor and the coupler connection.

Abstract: An apparatus for locking a transmission line in a tubular includes a first clamp segment configured to surround at least a portion of the transmission line of the tubular, the transmission line having a longitudinal axis. The apparatus also includes a second clamp segment configured to surround at least a portion of the transmission line, the second clamp segment and the first clamp segment configured to apply radial forces in opposite radial directions when the first clamp segment is engaged with the second clamp segment, the opposite radial directions being perpendicular to the longitudinal axis, the radial forces operating together to maintain the transmission line in a fixed position relative to the tubular and maintain tension in the transmission line.
