Patent ID: 8708727

Claim:
A high voltage plug-pin feed-through connector assembly, comprising: an outer shell of a predetermined radius having at least one through bore, a first end configured for exposure to a relatively low pressure environment, a second end configured for exposure to a high pressure subsea environment; at least one electrical feed-through pin extending through the at least one through bore and in sealing engagement with the through bore, the pin having a first end portion extending out of the first end of the shell and a second end portion extending out of the second end of the shell, the first end portion having a first end configured for communication with a respective conductor in a first electrical cable and the second end portion having a second end configured for communication with a respective conductor in a second, subsea electrical cable; the at least one feed-through pin comprising a conductive shaft of one or more pieces extending between the first and second ends of the pin and at least one insulation layer extending along at least a major portion of the length of the conductive shaft, the insulation layer having an enlarged, load-bearing portion located between opposite first and second ends of the insulation layer, the enlarged load bearing portion being of non-circular cross-section and comprising a pair of opposite projections defining a first diagonal dimension of the non-circular cross-section and a pair of connecting portions of reduced thickness extending between the projections and defining a second diagonal dimension of the non-circular cross-section of the pin which is less than the first diagonal dimension; and the at least one through bore having an enlarged portion engaging the enlarged, load bearing portion of the respective pin which is of shape at least substantially matching the shape of the enlarged load bearing portion of the pin.
