Abstract
An electrical connector for use in downhole environment and methods for use are provided. In one aspect, an electrical connector comprises a substantially cylindrical connector body having a first end and a second end. A groove is formed around an outer surface of the connector body wherein the groove has a first substantially conically beveled surface on a side of the groove proximate the second end. A back-up ring has a second substantially conically beveled surface and is adapted to act cooperatively with an elastomer seal to close an extrusion gap between the connector body and a surrounding surface when the elastomer seal is exposed to a positive differential pressure from the first end to the second end. In another aspect, a conical surface on the connector body is forced to engage a mating surface on a bulkhead, thereby forming a metal to metal seal.
