Abstract

A cartridge carrying electronic or other components is removably mounted in the breech of an adaptor module connected either in a streamer section or between opposing ends of adjacent streamer sections of a towed array. The adapter module is provided with channels for loosely guiding all but one strain member, one strain member being clamped to the module, with the longitudinal axis of the module breech being established by the longitudinal axis of the clamped strain member such that alignment of the cartridge is uniquely keyed to the single clamped strain member, the loose mounting of the unclamped strain members preventing differential forces being applied to the adapter module. In one embodiment, a spring-loaded pin and shuttle connector arrangement severs connection for an empty breech and provides for both point contact to an inserted cartridge and relatively long leakage paths so that any entrained sea water will not short out the adapter module or connector system.
