Sealing arrangements for electrical connectors providing electric power for oil operations and methods of manufacture

An electrical connector, comprising:

• a first conductor for receiving electrical power from and being connected to an electrical power source;
• an insulating body coupled to the first conductor, the insulating body having an electrical terminal that establishes electrical connections between the first conductor and a plurality of electrical terminal pins;
• a downhole cable coupled to a first electrical terminal pin of the plurality of electrical terminal pins, the first electrical terminal pin establishing an electrical connection between the electrical terminal and the downhole cable to provide the electric power to the downhole cable;
• and
• a plurality of sealing members each comprising a substantially cylindrical body having a plurality of peripheral ridges, having a semi-circular profile, protruding outward from the substantially cylindrical body, the plurality of sealing members protecting the electrical connections used to deliver the electrical power from the first conductor to the downhole cable, wherein:
• an interior of the substantially cylindrical body of the plurality of sealing members each further comprising two or more cylindrical sections connected to each other by a tapered cylindrical section tapering inward towards an axial center of the substantially cylindrical body, and
• the peripheral ridges and tapered cylindrical sections are separate and distinct from each other.

A method of manufacturing an electrical connector, comprising:

• providing a first conductor for receiving electrical power from and connecting to an electrical power source;
• coupling a first seal to the first conductor for protecting the first conductor;
• positioning the first conductor in an insulating body, the insulating body having an electrical terminal that establishes electrical connections between the first conductor and a plurality of electrical terminal pins;
• coupling a downhole cable to a first electrical terminal pin of the plurality of electrical terminal pins;
• establishing an electrical connection between the first electrical terminal pin and the downhole cable to provide the electric power;
• and
• protecting the downhole cable with a second seal coupled to the downhole cable,
• wherein:
• the first seal and the second seal each comprise a substantially cylindrical body and a plurality of peripheral ridges having semi-circular profile, protruding outward from the substantially cylindrical body,
• an interior of the substantially cylindrical body of the first seal comprising two or more cylindrical sections connected to each other by a tapered cylindrical section tapering inward towards an axial center of the substantially cylindrical body, and
• the peripheral ridges and tapered cylindrical sections are separate and distinct from each other.
