Abstract
To mate two complementary insulated electrical connectors while they are bathed in an electrically conductive medium, such as sea water, the two are first brought into mechanical contact with their respective matable electrical parts presented in axial alignment across a chamber defined therebetween. A non-conductive fluid is pumped under pressure through the chamber to flush electrically conductive medium and possible contaminants therefrom. Then an axial force is applied to the matable electrical part of one connector, forcing it axially across the chamber and into mating relation with the matable electrical part of the other connector. By preference, the matable electrical parts are pins and sockets and the interfacial chamber is flushed via ported bores in the sockets, using compressed air or a thick fluid such as hydraulic oil, transformer oil or polybutene. A typical use is to make and break an electrical connection for an electrically operated subsea oil wellhead flow control device.
