Abstract
An in-line connector for electrical cables used to conduct power to submersible pumps located down-hole in oil wells. The cable may be divided into lengths or sections a few hundred meters long, joined in series by the connectors, so that defective sections of cable can be replaced at the well site. Such cables typically comprise three heavy gauge conductors with high-temperature insulation and an outer wrapping of interlocking steel armor. The novel connectors are smooth in profile and sealed against the entry of fluids. The cable armor is preferably soldered into the ends of the connectors.
