ABSTRACT:
A terminal connector for high-current electrical cables includes an electrically-insulating casing of resin-impregnated glass fibers surrounding an end portion of an electrical cable, and a conductive member connected to the end portion of the cable and extending through an axial end of the casing. The casing has an inner collar which cooperates with two movable nuts to adjustably mount the conductive member in an axial end of the casing, and an outer collar to secure the casing to a base plate. The conductive member is formed with an annular groove which receives a resilient sealing ring. The sealing ring slides along an inner circumferential wall of the casing and seals the interior of the casing from its exterior throughout the entire adjustment range of the conductive member. A protective electrode attenuates electrical fields in this axial end, and an electrically-insulating housing having a fluid medium contained in its interior surrounds the casing.
