Underwater mateable and un-mateable electrical connector

A connector for sealably engaging and disengaging contacts therein, the connector comprising:

• a first unit having one or more first contacts, each first contact including an elongated shaft with a conductive tip;
• and
• a second unit having:
• one or more closed inner chambers therein, each inner chamber containing fluid, at least one of the one or more inner chambers being configured to contain one or more second contacts, each second contact being configured to engage one of the first contacts, each inner chamber corresponding to at least one end-seal configured to permit one of the first contacts to (i) sealably penetrate into the inner chamber and engage one of the second contacts within the inner chamber, and (ii) be subsequently sealably withdrawn from the inner chamber, at least a portion of each inner chamber being configured to be movable with respect to another portion of the inner chamber to permit balancing of pressure within the inner chamber to pressure outside of the inner chamber;
• and
• a closed cavity at least partially in contact with each inner chamber, the closed cavity containing an easily deformable material, the easily deformable material being an elastomeric gel, at least a portion of the closed cavity being configured to be movable with respect to another portion of the closed cavity to permit balancing of pressure of the easily deformable material within the closed cavity to pressure outside of the closed cavity.
