摘要： A tri-joint coupling for enabling the streaming and retrieving of a towed ray system having a single towcable and multiple towed array lines without disconnecting the lines from the towcable. The system is capable of being used on state-of-the-art inboard submarine handling systems. The tri-joint coupling is circular in cross-section at the single towcable end and elliptical in cross-section at the multiple towed array line end. The elliptical end of the coupling has three coupling inserts that are circular in cross-section and have electrical/optical connectors that connect individual electrical/optical conductors on the cable side to individual electrical/optical conductors on the multiple array side.
