Wellbore tool swivel connector

摘要

A swivel connector for interconnecting a wireline cable with a logging tool includes an elongated tubular body member having a cavity for supporting one or more slipring assemblies. An elongated shaft is disposed partially in said body member and extends from a lower end thereof and is supported on rolling element bearings. The shaft is connected to the rotors of the slipring assemblies while the stator members of the slipring assemblies are held stationary in relation to the body member by an elongated axial key. Flexible electrical conductors from the wireline cable are connected to the stator and flexible conductors are connected to the slipring rotors and extend through an axial passage in the shaft toward a plug for connecting the conductors to the logging tool.
