Abstract
A coaxial wet connector for connecting coaxail conductors of electromechaal ocean cables underwater either by a diver or submersible manipulator. The connector comprises a male section having a male inner conductor extending outwards from a concentric male outer conductor and a female section containing a spring biased shuttle piston for receiving the male inner conductor upon mating. An O-ring wiping seal wipes the male inner conductor clean of water as the male inner conductor drives the shuttle piston rearward within a female housing until electrical interconnection between the male and female sections is completed. A pressure compensating bladder removes water trapped adjacent an interconnection surface during mating and returns the water to the interconnection surface during decoupling thereby preventing a hydraulic lock between the male and female sections. A plurality of latch members pivotably connected to the male section and operable to engage a ridge on the feamle section is provided for transferring the mechanical forces from the female outer conductor to the female housing to the male housing and back to the male outer conductor.
