Abstract

An apparatus for transmitting data between downhole tools is disclosed in oneembodiment of the present invention as including an annular core (70) constructed of amagnetically-conductive material. At least one conductor (72), electrically isolated from theannular core, is coiled around the annular core. An annular housing (28) constructed of anelectrically conductive material is used to partially enclose the annular core and theconductive coil. The annular housing is shaped to reside within an annular recess (76)formed into a surface of a downhole tool, and is electrically insulated from the surface.A biasing member (96) is used to effect a bias between the annular housing and the annularrecess, urging the annular housing in a direction substantially perpendicular to thesurface.
