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 housing having an upper and a lower end. The downhole cable has electrical conductors which are separately covered by insulation layers. The downhole cable extends through the upper end and into the housing, and then is electrically connected to the electric motor through the lower end of the housing. Two insulating blocks are provided in the lower end of the 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. An elastic sealing ring is disposed within the housing, intermediately between the two insulating blocks. An epoxy layer are disposed within the upper end of the housing.
