ABSTRACT:
A connector for a small diameter towed sonar array is used to couple similar sections together. Each section includes a sheath or tubing of flexible plastic material such as polyvinylchloride clamped at each end tightly around a cylindrical metal coupling member having threads extending external of said tubing. Held adjacent the internal surfaces of the coupling members at the outside ends thereof are a pair of connector members which include a plurality of concentric conductor tracks. When adjacent sections are joined, these conductor tracks are pressed tightly together, partly as a result of the force exerted by flexible plastic spacers which abut against internal shoulders of the coupling members and the connector, urging the connector members outwardly against each other. A glass header member with a plurality of conducting pins therethrough is sealed to the inside of the coupling member, and wires therefrom connect with the individual conductor tracks, thereby providing electrical continuity and a high pressure seal across the junction. Also located within each of said coupling members are a pair of mating clamp members which engage a cylindrical collar having a mating wedging surface to capture and retain a plurality of rope members of strong synthetic material. Electrical conductors also pass through passageways in these clamp members and are connected to the conducting pins. The sections are joined by means of a collar having right hand-left hand internal threads engaged with the external threads of the coupling members to thereby pull said coupling members together.
