Abstract

A cartridge retention system includes a cartridge carrying electronic, compressed gas or other components which has a spring-loaded button at one end and which is removably mounted in the breech of an adapter module connected either in a streamer section or between opposing ends of adjacent streamer sections of a towed array. The cartridge is demountably retained within the adapter by providing an adapter housing with a breech which is somewhat longer than the cartridge, and by providing the housing with an overlying two part shell which is rotatable about the housing, with one of the shell parts containing an aperture to accommodate cartridge insertion and with both parts containing an internal circumferential groove adapted to coact with the spring-loaded button on the cartridge to move the cartridge from one end of the breech to the other end upon rotation of the shell. The part of the shell opposite that containing the cartridge insertion aperture is provided with a button retaining aperture such that upon a 180.degree. revolution of the shell, the button is captured in the button retaining aperture to secure the cartridge in the breech such that the cartridge is pressed to the opposing end of the breech and into a connector at the opposing end. When the cartridge is inserted through the shell and into the breech, the button is depressed prior to rotating the shell, with the groove-button camming action forcing the cartridge to the opposite end of the breech.
