Abstract
Abstract A high tension feeding cable, includes: a body of cable which has a high tension core for supplying a high tension current, and an inner covering layer provided on the outer surface of said high tension core, cylindrical terminals, attached to said cable body, for connecting the high tension core to mating electrical apparatus, said cylindrical terminal having a connecting section which connects the inside and outside of the cylinder, said cylindrical terminal being attached to said cable body so as to have the connecting section positioned in the neighborhood of the end surface position of said cable body, and terminal caps, provided on the end sections of the body of cable with the cylindrical terminal, for protecting said cylindrical terminals and further for connecting the high tension feeding cable mechanically to mating electrical apparatus. The terminal caps have (i) a surrounding section that surrounds at least a part of said cylindrical terminal and cable body, and (ii) a projected section that projects from the outside surface to the inside surface of the cylinder through the connecting section in said cylindrical terminal. The high tension feeding cable eliminates positional slippage of the connecting terminal and the terminal caps with respect to the cable body.
