  • Patent number: 7331806
    Abstract: 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.

  • Patent number: 6929492
    Abstract: A cable connector, connector apparatus and method for introducing fluid to a cable. The cable connector, connector apparatus and method configured to form an electrically resistive barrier between components internal to the connector and the environment surrounding the connector after the introduction of the fluid. In one embodiment, a connector comprises a chamber adapted to affix a cable internal to the chamber, wherein the chamber is in fluidic communication with an injection port. The connector further comprises a valve operable to restrict fluid from entering the injection port from the chamber when a fluid source discontinues the introduction of fluid into the injection port. In another embodiment, a method of the present invention involves the application of an insulating material into an injection port of a connector following the application of a dielectric fluid, thereby forming an electrically resistive barrier between components internal to the connector and the external environment.
