Abstract
Abstract A connectable and releasable electrical wet connect for transmitting electrical signals in a well drill string includes retrievable coacting telescoping male and female member electrical connectors. The male member includes a support shoulder for supporting the wet connect in the drill string, a passageway for the flow of fluids, an electrical contact, a tapered and insulating seal and a fishing shoulder. The female member includes a telescopically engageable electrical receptacle, and a tapered and insulating female seal. The wet connect telescopically connects and disconnects in the drill string and electrically isolates the electrical signal transmitted through the wet connect from the fluid in the drill string.
