Abstract

Pass-through for electrical connections, characterized in that it comprises a metallic rod, electrically good conductor; a tubular insulator mounted on said shank, and a resistant bushing externally secured to the tubular insulator, the shank of which is slightly smaller in diameter than the inner one of the tubular insulator and is topped, on the one hand, by an axially grooved or polygonal contoured head and an end connector, while from the opposite end it has a threaded section, the portion being limited between said threaded section and the polygonal head of length equal to or slightly less than the tubular insulator, and whose insulator has internally, at both ends, a central box with a polygonal contour to receive, on the one hand, the grooved head mentioned, and on the other, a ring, also of polygonal or axially grooved contour, to prevent the relative rotation between the rod and the insulator, being mounted in addition on the threaded section from said rod a tightening nut and means or connection elements; the heavy-duty bushing being mounted on the tubular insulator threaded on its outer surface and topped by one of its ends in an external widening.
