Abstract
A high pressure connector for connecting an insulated electrical conductor or wire (24) to a recessed electrical contact (16) in a plug housing (10). The connector has a diameter smaller than the diameter of the plug housing (10) and is positioned within the plug housing (10) to electrically connect the wire (24) and the recessed electrical contact (16) without permitting high pressure well fluids from entering plug housing (10). A locking retainer (34) tightens a ferrule or seal (32) to provide a metal-to-metal seal that prevents pressurized well fluid from intruding into the plug housing (10). An electrical contact such as connector (44) engages conductor (30) of wire (24) and electrical contact (16) while permitting relative axial movement therebetween to facilitate tightening of locking retainer (34) to plug housing (10). Other retainers (76) and seals (72,80) can provide a metal-to-metal connection to prevent the well fluid from contacting the interior of plug housing (10). A test apparatus (84) can be adapted to test seals before the connector is installed downhole in the well."
