    摘要: An inductive coupling system including a mandrel and an inner sleeve and outer housing that surround and rotate relative to the mandrel the system also includes a mandrel electronics system and a housing electronics system that communicate electronically using a mandrel inductive coupler and a housing inductive coupler. The mandrel electronics system may also communicate with equipment on the surface. Alternatively, the system may include a mandrel and first and second mandrel electronics systems in different mandrel sections. The first and second mandrel electronics systems communicate electronically using a mandrel inductive coupler. Also alternatively, the system may include a mandrel and an inner sleeve and outer housing that surround and rotate relative to the mandrel. The system also includes a mandrel electronics system and a housing electronics system that communicate electronically using a housing inductive coupler.

    摘要: An apparatus includes a pair of connectors, two or more conductive paths formed in each connector in the pair of connectors, and a shroud encompassing at least a portion of the pair of connectors. The pair of connectors includes a first connector and a second connector. The first connector is substantially more flexible than the second connector, and each connector in the pair of connectors includes a bulkhead. Each of the two or more conductive paths in each connector in the pair of connectors is electrically isolated from all other conductive elements in the pair of connectors. The shroud is located between the bulkheads and disposed about the pair of connectors when the pair of connectors are coupled together electrically.
