Cable connectors with internal fluid reservoirs
Cable terminations, junctions, or connectors having a cable affixed therein are provided, which include an internal cavity that is capable of (1) holding a selected volume of remediation fluid and (2) supplying it to the cable. Several embodiments of the cavity are capable of holding the remediation fluid under pressure for prolonged periods of time and through various environmental conditions such as temperature, moisture and sun exposure. Several embodiments of the internal cavity are divided into two or more chambers that are in physical communication through the opposition of pressure but which are chemically isolated. In several embodiments, an actuation device, such as a spring or compressed gas, pressurizes the fluid. Throughout the embodiments, individual access port(s) provide controlled access to the various internal chambers.

7. The cable connector of claim 4 , wherein the actuator chamber contains fluid under pressure.
8. The cable connector of claim 1 , wherein the auxiliary chamber is exposed to externally applied pressure for driving fluid from the auxiliary chamber into the primary chamber.
9. The cable connector of claim 8 , wherein the externally applied pressure is regulated.
10. The cable connector of claim 1 , wherein the auxiliary chamber is exposed to internal pressure for driving fluid from the auxiliary chamber into the primary chamber.
11. The cable connector of claim 1 , further comprising a valve conditionally placing the auxiliary chamber in fluid communication with the primary chamber.
12. The cable connector of claim 11 , wherein the valve is operable to permit passage of liquid in one direction between the auxiliary chamber and the primary chamber.
13. The cable connector of claim 12 , wherein the valve is further operable to prohibit passage of gas between the auxiliary chamber and the primary chamber.
14. A cable connector for introducing fluid to a cable affixed in a first chamber internal to the cable connector, the cable connector comprising:
an injection port exposed to at least one exterior surface of the cable connector, the injection port being connected in fluid communication with the first chamber internal to the cable connector for supplying fluid thereto;
a second chamber internal to the cable connector, the second chamber connected in fluid communication with the first chamber; and
means for driving fluid disposed in the first chamber into the cable affixed therein.
15. A cable connector for introducing fluid to a cable affixed in a first chamber internal to the cable connector, the cable connector comprising:
an injection port exposed to at least one external surface of the cable connector, the injection port connected in fluid communication with the first chamber internal to the cable connector; and
a second discrete fluid chamber having a variable volume, the second chamber connected in fluid communication with the first chamber.
16. The cable connector of claim 15 , further comprising a third chamber fluidly isolated from the first and second chambers, wherein the third chamber applies pressure on fluid disposed in the second chamber for forcing the fluid in the second chamber into the first chamber.
17. The cable connector of claim 15 , wherein the variable volume of the second chamber is dependent on operational parameters of the cable connector.
18. A cable connector for introducing fluid to a cable affixed in a first chamber internal to the cable connector, the cable connector comprising:
an injection port exposed to at least one exterior surface of the cable connector, the injection port being connected in fluid communication with the first chamber internal to the cable connector for supplying fluid thereto; and
means for driving fluid disposed in the first chamber into the cable affixed therein.
19. A cable connector, comprising:
a housing including a fluid chamber;
a cable section disposed within the fluid chamber; and
pressurized fluid disposed within the fluid chamber.
20. The cable connector of claim 19 , further comprising a biasing device for pressurizing the fluid present in the fluid chamber.
21. A cable connector for introducing fluid to a cable affixed in a first chamber internal to the cable connector, the cable connector comprising:
a second chamber internal to the cable connector, the second chamber fluidly isolated from the primary chamber; and
a pressure generator disposed in the second chamber, wherein the pressure generator applies pressure against fluid occupying the first chamber.
