Abstract:
1. A pothead connector for connecting a plurality of electrical cables to a terminal block of a submersible motor head, the pothead connector comprising: a housing defining a plurality of passageways extending in a longitudinal direction, each passageway configured to receive one of the electrical cables; wherein each passageway is defined at least partly by a longitudinally extending surface and a tapered surface that extends angularly inwardly relative to the longitudinally extending surface; a plurality of shrouds having first and second ends, wherein the first end of each shroud is disposed in one of the passageways, each shroud configured to encircle the electrical cable received in that one passageway; and a plurality of packing seals, each packing seal disposed in one of the passageways and configured to encircle the cable received in that one passageway, wherein each packing seal is sandwiched between the first end of the shroud and the tapered surface in that passageway; wherein the shroud is biased in the longitudinal direction so as to compress the packing seal outwardly against the tapered surface and inwardly against the electrical cable, to thereby form a liquid impermeable seal between the shroud and packing seal and a liquid impermeable seal between the packing seal and housing.
