Abstract
An electrical cable connector, such as a pothead for a submergible motor, employs a fluid sealing system that provides for passage of electrical conductor members through tubular bodies while preventing passage of fluid therethrough. The fluid sealing system includes semi-rigid elastomeric packing discs and gland discs. Each packing disc has flexible annular lips that seal upon either an internal surface of a tubular body or an external surface of a conductor member extending through the packing disc. Each lip has a tapered surface engaged with a corresponding annular chamfer on a gland disc; the angles or contours of the lip surfaces and the chamfers being mismatched so as to apply a radial compressive force to each lip. A compression disc is urged into engagement with a gland disc by springs surrounding a portion of the compression disc by a nut or retainer ring. Terminal structures at ends of the electrical conductor members include sleeves which are sealed to the insulation of the conductor members to prevent fluid passage within the conductor members.
