Abstract:
A wire end connection construction comprising:an equipment terminal fitting disposed on an equipment and having a free end;a substantially cylindrical terminal chamber wall projecting from the equipment and surrounding the equipment terminal fitting, said cylindrical terminal chamber wall having an inside diameter substantially greater than the equipment terminal fitting such that said cylindrical terminal chamber wall is spaced outwardly from said equipment terminal fitting, said substantially cylindrical terminal chamber wall further having an end projecting beyond said equipment terminal fitting by a selected equipment terminal recess distance;a wire terminal fitting unitarily formed from a conductive metal and having opposed first and second longitudinal ends, the first longitudinal end of the wire terminal fitting defining a substantially cylindrical barrel securely connected to a wire, the barrel having an outside diameter less than the inside diameter of the cylindrical terminal chamber wall, the second end of the wire terminal fitting being formed into a substantially tubular connection portion dimensioned for electrical connection over the equipment terminal fitting, and a tapering guide portion having a small diameter in proximity to the connection portion and a large diameter adjacent the barrel, the large diameter of the tapering guide portion being substantially equal to the outside diameter of the cylindrical barrel, said guide portion being spaced from the second end of the wire terminal fitting by a distance less than the equipment terminal recess distance;a seal member sealably surrounding and engaging portions of the barrel adjacent the first end of said wire terminal fitting and portions of the wire connected with the wire terminal fitting such that the connector portion, the guide portion and portions of the cylindrical barrel of said wire terminal fitting are exposed and project beyond the seal member by a projecting distance approximately equal to the projection of the cylindrical terminal chamber wall from the equipment; anda cylindrical sealing tubular portion projecting unitarily from said seal member a distance greater than the projection of the wire terminal fitting from the seal member, said sealing tubular portion having an inner cylindrical surface defining an internal diameter selected for sealing engagement around said terminal chamber wall;whereby the substantially cylindrical terminal chamber wall is slidable along the tapering guide portion and the cylindrical barrel of the wire terminal fitting for guiding the tubular connection portion of the wire terminal fitting toward the equipment terminal fitting and into mating engagement therewith.
