US Patent 10230222 Injection electrical connector

An insert for constructing a cable accessory used to inject a fluid into a cable. The cable accessory has an outer body defining an interior configured to house a conductor of the cable. The outer body includes an injection port with an internal channel configured to receive the fluid. The insert has first and second portions. The first portion is configured to line a portion of the interior of the cable accessory. The first portion has a first through-channel configured to allow the conductor of the cable to pass at least partway therethrough. The second portion is configured to line the internal channel of the injection port. The second portion has a second through-channel in fluid communication with the first through-channel. The insert is less permeable to the fluid than the outer body of the cable accessory. The insert may be molded into the outer body.
