Abstract

A method for making a wet mate electrical connection in an underground borehole with a static downhole conductor pin that is protected from the borehole environment by a non-sealed shuttle and a moveable mating receptacle/conductor which presses on the outer body of the shuttle thus causing it to move along the conductor pin tube. The conductor pin inserts into the receptacle connector and connects to the contacts. Both connectors are filled with a dielectric fluid for isolation and are pressure balanced to counteract volume variation due to temperature changes. The moveable receptacle connector uses a non-conductive pin which is replaced by the conductor pin and provides a surface for wiper seals. As mating occurs, the conductor pin replaces the non-conductive pin, so no volume change occurs, and pressure change is eliminated. A reverse labyrinth isolates the heavy dielectric of the static connector from borehole fluid.
