Abstract
A connector of electromagnetically insulative material includes a shaft section on a drive shaft end and a matching probe section on an eddy current probe mating to the shaft section with face to face contact surfaces to prevent electromagnetic fields from propagating along the surfaces. The connector includes upper and lower portions with power line connecting pins and matching sockets in the upper portions of the sections and communication line connecting pins and matching sockets in the lower portions of the sections. The pins and sockets are fitted within electrically nonconductive inserts within probe and shaft section bores, the inserts having magnetic permeabilities less than those of the probe and shaft sections. The section matching surfaces at the power line upper portion are spaced apart longitudinally from the section matching surfaces at the communication line lower sections by a planar ledge on each of the upper and lower sections which ledges rest in mutual face to face contact when the union is connected. A plug extends from a shaft section outside corner into a trepan at a probe section inside corner to further impede electromagnetic field leakage.
