Abstract
An electric submersible pump is provided having a pothead connector for use to connect a downhole cable to an electric motor of the submersible pump. The pothead connector has a tubular housing having an upper and a lower end. The downhole cable has electrical conductors which are separately covered by insulation layers. Lead sheaths separately extend around each of the insulation layers to encase each of the electrical conductors. The downhole cable extends through the rearward end and into the tubular housing, and then is electrical connected to the electric motor through the lower end of the tubular housing. An insulating block is provided in the lower end of the tubular housing for separating electrical conductors in alignment for mating with a connector mounted to the electric motor. A conductor pin is secured to the insulating block and to each of the conductors. The conductor pin abuts against an internal shoulder within a bore of the insulating block. An insulating sleeve, which slides over each conductor pin and into the bore of the insulating block, is threadedly connected to the insulating block urging the conductor pin against the internal shoulder. A lead based alloy s…
