Patent ID: 7900968

Claim:
A gap sub assembly comprising: a female conductive component having a threaded connecting end; a male conductive component having a threaded connecting end inserted into the connecting end of the female conductive component, whereby the connecting ends of the male and female conductive components matingly engage with each other; at least one of the male and female conductive components having a cavity in a surface of its connecting end; and an electrical isolator component comprising a substantially dielectric and annular body located between the connecting ends of the male and female conductive components such that the conductive components are mechanically coupled together but electrically isolated from each other at their connecting ends, the annular body having a barrier portion protruding into the cavity of at least one of the connecting ends of the male and female components to impede at least the rotation of the conductive component relative to the annular body; and wherein the annular body is located between and around the threaded connecting ends of the male and female conductive components and the barrier portion is positioned relative to the corresponding conductive component to resist rotation thereof relative to the electrical isolator component.
