Abstract : Sonar array cable is typically provided in lengths comprising hydrophone arrays and associated electronics and transmitter can components, each cable length or section having one of each of these components housed therein. These sections are relatively stiff and unbendable, requiring that they be connected with relatively bendable intermediate segments. These intermediate segments are susceptible to excessive bending that can lead to failure of thc wiring provided therebetween. The wiring in these intermediate bendable segments is provided in the form of a coil, each of which coils is rigidly connected to the transmitter and electronics in one cable section, and the other end of the coil being connected electrically to the wiring associated with the hydrophone array in an adjacent cable section. Each coil is encased in relatively soft urethane material, preferably in one portion of the bendable segment, another portion of the bendable segment having the coil connected at its other end to a relatively stiff urethane material associated with the transmitter can and associated electronics.
