ABSTRACT:
A housing enclosing an electrical connector has a capable open end through which the connector is received and a closed end having a passage that is sealably mounted in alignment with a through opening in a pressure hull. The connector is isolated from a marine environment by a dielectric liquid that fills the housing and immerses the connector. An end cap closes the open end of the housing to prevent loss and contamination of the liquid and includes a sealable opening through which a first member of the connector is admitted and locked to the housing. A feed-through portion of the connector mates with the cable end portion and is sealably fitted within the passage to provide an electrical connection through the hull. In an embodiment for in-line cable connections, the closed end carries a second member of the connector, corresponding to the first member, which is locked and sealed in the passage. A bleed hole in the housing communicates the environment to the liquid which pressurizes the housing and seals the connector to prevent corrosion. The bleed hole also operates to relieve pressure within the housing caused by expansion and contraction of the liquid due to environmental temperature changes.
