Abstract
A magnetically conductive electrically insulating (MCEI) trough for an inductive coupler in a drill pipe, drill string, and other downhole tools. The MCEI trough may be a ring or two or more ring segments. The trough may comprise interior side and bottom walls forming an open channel. The interior walls may comprise one or more axial flutes. An exterior wall may be spaced apart from the interior walls. The spaced apart interior and exterior walls may form a top surface. The exterior wall may comprise one or more flutes. The flutes may protrude from the respective wall surfaces, or the flutes may protrude into the wall surfaces. A wire coil may be laid within the open channel. The wire coil may comprise axial corrugations. The axial corrugations may couple with the axial flutes of the interior side walls. The wire coil may comprise wire strands laid within the trough.
