Retractable electrical/optical connector

摘要

A down-hole tool includes a first and second portion that are moveable relative to one another, but are electrically coupled together. A rigid tube formed into a helical coil extends between the first and second portions. The helical coil is expandable and compressible in response to movement between the first and second portions. A conductor is positioned within the helically wound tube and is adapted to pass electrical signals between the first and second portions.
