Link module for a downhole drilling network
First Claim
1. A downhole repeater assembly comprising:
- a host drill string pipe comprising a threaded pin end comprising an integal primary and integral secondary shoulder and a threaded box end comprising a primary shoulder and an oversize bore adjacent the primary shoulder;
a cylindrical insert housing, characterized by a proximal end and a distal end, having a substantially cylindrical wall having an outer rounded surface about equal to the oversize bore, the cylindrical wall defining a central bore passing therethrough;
the cylindrical insert housing further formed to define at least one recess in the outer rounded surface of the cylindrical wall;
a repeater circuit located within the at least one recess;
the cylindrical insert housing further comprising a radial annular recess perpendicular to the central bore and formed into at least one of the proximal end and the distal end; and
an axial annular transmission element located in the annular recess, the axial annular transmission element operably connected to the repeater,wherein the cylindrical housing is inserted into the oversize bore and fixed in place using a secondary shoulder insert comprising engagement grooves.

Abstract
A repeater is disclosed in one embodiment of the present invention as including a cylindrical housing, characterized by a proximal end and a distal end, and having a substantially cylindrical wall, the cylindrical wall defining a central bore passing therethrough. The cylindrical housing is formed to define at least one recess in the cylindrical wall, into which a repeater is inserted. The cylindrical housing also includes an annular recess formed into at least one of the proximal end and the distal end. An annular transmission element, operably connected to the repeater, is located in the annular recess. In selected embodiments, the annular transmission element inductively converts electrical energy to magnetic energy. In other embodiments, the annular transmission element includes an electrical contact to transmit electrical energy directly to another contact.
