Water Impermeable, Easy Disconnect Electrical Cable Connector for Deep Sea Applications

Williams-Pyro, Inc., proposes to develop a line of robust power and data connectors that are completely water impermeable, even under prolonged exposures to high and varying water pressures (up to 1800 psi) associated with deep-sea applications. In this solution, Williams-Pyro proposes to electrically connect standard Electrical Hull Fittings (EHFs) on Navy submarines to Dry Deck Shelters, Advanced Seal Delivery Systems, or other outboard or peripheral systems using electrical connector technology that is rugged, lightweight, cost-effective, safe, efficient, corrosion-resistant, relatively lightweight (< 1 lb), reliable enough for frequent connection and disconnection, and easy to assemble/connect/disconnect without special tools or training. This solution will encapsulate a hydrophobic gel material within an enclosed connector, such that connector pins are pressed through the gel to mating sockets, repelling away any water in the process. The compartment containing the gel will be separated from the external environment by one or more diaphragms, which will maintain the gel within the connector and serve to wipe water from the pins as they are passed through the diaphragms and into the gel to the sockets. A “grease zerk” reservoir device will be incorporated to replenish any gel lost over time.
