Seismic streamer connector assembly

A marine acoustical streamer section for an elongated acoustical streamer cable made up of plural sections connected serially together, the streamer section comprising an elongated streamer jacket of generally cylindrical tubular configuration of predetermined diameter including a bundle of signal wires and plurals strain wires extending through the interior thereof and connector couplers at opposite ends thereof adapted to be secured in mated relation without rotation to companion connector couplers of the same construction at the ends of adjacent streamer sections, each coupler comprising an axially elongated coupler body having a fully cylindrical anchoring head portion at an end thereof and an axially elongated half cylindrical segment portion extending integrally from said anchoring head portion having a distal end spaced from the latter, the half cylindrical segment portions of the companion couplers when secured in mating relation collectively forming a cylinder coaxial with said streamer jacket of a diameter substantially corresponding to the streamer jacket diameter, the coupler body defining a partially segmented tubular shell having a concave cavity extending through the length of said segment portion, said anchoring head portion including strain cable anchoring means and means for passing the bundle of signal wires therethrough, the insulator core assemblies removably received in said concave cavities having multiterminal electrical pin and socket type plug panels supported in the concave cavity of the associated coupler body to be disposed in confronting immediately adjacent parallelism with and connected to a mating multiterminal electrical plug panel of a companion coupler to be mated therewith, the insulator core assemblies for each coupler body having resilient means interposed between the core assembly and the surrounding coupler body and between its associated electrical plug panel and the panel-supporting portions of the associated core assembly disposing them in floating relation relative to the coupler body so that deformation of the stress carrying coupler body is not transmitted to its associated electrical plug panel, and assembly means adjacent to the ends of the half cylindrical segment portions of the coupler bodies remote from their anchoring head portions for securing the coupler bodies together with their half cylindrical segment portions mated together, said assembly means comprising a locking ring rotatably supported on the anchoring head portion of its associated coupler body for rotary movement about the axis of the coupler body between angularly spaced locking and unlocking positions and having an interlock portion disposed to overlap and interlock with the distal end portion of the elongated half cylindrical segment portion of the companion coupler when those coupler bodies are mated together and the locking ring is in the locking position.
