ABSTRACT:
A plurality of separate electrical power supply lead wires each have an exposed end portion projecting from a surrounding insulation. Each lead wire is crimped onto a corresponding collett-like socket member which is inserted into an insulator sleeve disposed within a bore formed within a submersible electric motor housing. Each socket member receives a conductor prong member which projects into the sleeve and is crimped to a stator lead wire. A tubular bushing, a resilient ring and a tubular nut surround the lead wire and project into the upper end of the bore for producing a fluid-tight seal between the insulation on the lead wire and the housing and to press the socket member axially into the sleeve which cams the socket member firmly against the conductor prong member. The conductor prong member projects through a hole within an annular lightning arrestor electrode which defines an electrical gap surrounding the prong member. The prong member is also sealed to the motor housing by a resilient ring which is compressed axially within the lower end portion of the bore by another tubular bushing and a tubular nut which surrounds the stator lead wire.
