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.

1. A device for attaching an end of an electric cable to the head of a motor, the electric cable having at least one conductor, the device comprising in combination:a housing; an upper insulating block, contained within the housing, having at least one bore therethrough for receiving a conductor; a lower insulating block, contained within the housing, having at least one bore therethrough for receiving the conductor, and wherein the bores of the upper insulating block and the lower insulating block share the same axis; a seal assembly of an elastomeric material, contained within the housing between the blocks, having at least one passage sharing the same axis as the bores of the upper and lower insulating blocks, the seal assembly having at least one inner lip that while in an undeformed condition has an inner surface that tapers radially inward relative to the axis of the bores of the upper and lower insulating blocks for sealing around the conductor, the seal assembly having an outer periphery that seals against the housing.
