Abstract: Each feed-through pin of a multiple-phase, high voltage plug-pin connector comprises at least one conductor having a first insulation layer extending along at least part of its length, the insulation layer having an enlarged, load-bearing portion of non-circular cross-section having oppositely directed projections, configured for engagement in a correspondingly shaped bore portion of the connector shell. The load-bearing portions may be of a rhomboidal cross sectional shape with rounded corners, with a first diagonal length shorter than a second diagonal length. The pins are spaced around the central longitudinal axis of the shell with the shorter diagonal of each load-bearing portion extending radially and the oppositely directed projections extending into the radial spaces in the shell between adjacent pins. This arrangement allows space within a limited diameter feed through hole for the enlarged, load-bearing shoulder portions of the insulation layer.
