  • Flex joint
    Patent number: 5769558
    Abstract: A flex joint is disclosed for connecting two cylindrical instrument housings of a downhole instrument assembly that will bend as required to allow the instrument housings to move through a curved section of a well bore. The joint includes spaced tubular connectors for connecting the joint to the cylindrical housings. The connectors are connected by a flexible cable or thin walled cylindrical tube. One or more helical springs extend between the connectors and are held in compression to urge the connectors toward an in-line position while allowing the joint to bend as required for the cylindrical instrument housings to travel through a curved section of a well bore.
