Abstract
Various embodiments of a downhole tool with a telescoping conductor member are provided. In one aspect, a downhole tool is provided that includes and a mandrel telescopically positioned in the housing. The mandrel and the housing define a pressure compensated substantially sealed chamber containing a volume of a non-conducting fluid. A conductor member is positioned in the housing for providing an electrically conducting pathway. The conductor member has a first segment and a second segment. The first segment is moveable with the mandrel and relative to the second segment. A portion of the conductor member is electrically insulated from an ambient fluid by the non-conducting fluid. A first biasing member is provided for maintaining a conducting pathway between the first segment and the second segment. The tool provides for electrical transmission in a telescoping tool.
