Abstract
Abstract A structure for connecting together separate elongated small diameter sonar arrays and nonacoustic modules includes a pair of cylindrical housings which telescope together with a keyway to prevent radial movement and each of which includes means for anchoring a plurality of strength members in the form of ropes of aramid fiber. The outside one of the two telescoping housings includes external threads and an external groove for retaining a seal. The inside cylindrical housing includes two external seals, one of which is in contact with the other housing, and an external groove and shoulder. A sleeve member surrounds the telescoping housing members and includes an internal surface in contact with the other two seals, internal threads engaged with the external threads, and a shallow internal groove carrying a radially expanding retaining ring which, in operation, wedges into the shoulder and against the sleeve to transfer the load from housing to housing. A series of radial passages permits entry of a tool or tools to compress the retaining ring into the external groove on the inside cylindrical housing to permit separation of the cylindrical housing from the sleeve. Multipin electrical connector members are keyed and sealed into each of the cylindrical housings with wiring from the sonar arrays separated into individual conductors and connected to the proper connecting pins with the wires, connections and the pins encapsulated in potting compound.

Claim 1
Independent Claim
374 words
A connector assembly for fastening together two elongated sonar arrays or nonacoustic modules, each of said arrays including a length of flexible hose, hydrophones, wiring, a plurality of strength members, and a hydrocarbon dielectric material in said hose, which arrays are towed through a body of water, said assembly comprising first and second generally cylindrical coupling housings with one said housing including a section which telescopes over the other said housing, said housings including a key and keyway preventing relative radial movement of said housings, each said housing having an internally threaded cylindrical section at its end opposite said key and keyway and one end of a section of flexible hose clamped to the exterior surface of each said internally threaded cylindrical section, strength member retaining means threadedly engaged with the internal threads of each said cylindrical coupling housing, electrical plug members carried internally of each of said cylindrical coupling housings with female electrical connecting pins in one said plug member and male connecting pins in the other said plug member, a plurality of electrical wires connected to said pins, and potting compound within said coupling housings enclosing said wires and portions of said pins, fluid seal means adjacent each said plug member for effecting a fluid seal between each said plug member and the internal surface of its cylindrical coupling housing, and a coupling sleeve member carried on the one of said coupling housings which slips inside the other, said sleeve member having internal threads engaged with external threads on the other said coupling housing, and a shallow annular groove on the inside surface of said sleeve member, liquid seal means between each of said cylindrical coupling housings and said coupling sleeve member, a groove and a shoulder on the surface of said one coupling housing, a retaining ring in said shallow annular groove which in operation is wedged into said shoulder to prevent tensile forces on said assembly from separating said cylindrical coupling housings, and radial passageways in said coupling sleeve member communicating with said shallow annular groove such that means exerting force through said passageways can compress said retaining ring into said groove on said one coupling housing to permit separation of said coupling sleeve member from said one coupling housing.
