Patent ID: 7533461

Claim:
A method for interconnecting electrical conduits in an underground borehole by means of an electrical connector comprising a static and a moveable connector part, which parts comprise pairs of intermeshing electrical contacts that are circumferentially spaced around the periphery of a central throughbore within the static connector part, which method comprises: installing the static connector part substantially coaxially within the borehole or a borehole tubular such that the central throughbore provides a passage for fluid and debris and for access to the section of the borehole beneath the static connector part after retrieval of the moveable connector part; and lowering the movable connector part into the borehole on top of the static connector part such that the pairs of electrical contacts intermesh and that fluid and debris are discharged via the central throughbore into the section of the borehole beneath the static connector part; wherein at least one connector part comprises at least one electrical contact, that is arranged in a sealed chamber comprising a dielectric fluid and an entrance opening which is configured to receive a mating electrical contact and which comprises a seal which is configured to inhibit contact between the dielectric and borehole fluids and to surround the electrical contacts when mated and to remain in sealing contact with the mating electrical contact after the electrical connection has been established by the connector.
