Electrically insulated connector bands for Downhole Electrical Disconnect Tools provide power and/or data communication downhole are made from metal having sufficient strength and corrosion resistance to eliminate the need of any vacuum and sealed pressure compensation assembly while being exposed to wellbore fluids. The electrical insulation is achieved by having portions of the connector bands coated with electrically insulating material. An uncoated section of each connector band will provide the electrical path between the male and female mandrels.
