  • Patent number: 4204739
    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.

  • Patent number: 4053196
    Abstract: A plurality of separate electrical power supply lead wires each have an exposed end portion projecting from a surrounding insulation. The end portions are slidably received within corresponding collett-like socket members supported by an insulator plug disposed within a bore formed within a submersible electrical motor housing. A strain relief washer engages the socket members and supports a resilient gland member which has corresponding bores for slidably receiving the insulation on the lead wires. A bushing and tubular nut surround the lead wires and project into the upper end of the bore to provide for compressing the gland member axially within the bore for producing a fluid-tight seal between the insulation on each lead wire and the housing and to press the strain relief washer against the socket members for gripping the lead wires.
