ABSTRACT:
An electrical coupling is provided suitable for interconnecting multiple conductors between first and second downhole tools, such as logging tools. The male and female coupling bodies are sealed from the environment such that the mated connector and the conductors within the interior of the mated coupling are sealed from the hostile downhole environment. A threaded ring removably connected to each connector subassembly engages a stop surface on the respective coupling body to limit axial movement of each connector subassembly toward the conductor receiving end of that body. Backup seals provide sealing engagement between each connector subassembly and the respective coupling body, so that fluid cannot be passed along either conductor to the electronics in the adjacent downhole tool housings interconnected with each coupling body if the primary seal between the coupling bodies should fail. According to the method of the present invention, each connector subassembly may be inspected or replaced, if necessary, and the various O-ring seals replaced by removing each connector subassembly from the conductor receiving end of its respective coupling body. The reliability of the coupling is enhanced, the coupling can be easily repaired, no slack need by provided along the length of the conductor, and the mated coupling seals the interior of the coupling and the adjacent electronics from the high pressure downhole fluids.
