摘要

Improvements in the construction of ferrules and lamp holders for incandescent lamps, characterized by making the ferrule of an insulating material with its smooth outer surface, the contacts of this ferrule constituting the same conduction wires that come out of the glass globe of the lamp which, after passing inside the bushing they are folded over the edge thereof and are applied longitudinally in diametrically opposite positions on the outer surface of the bushing, to which they are conveniently fastened, the corresponding lampholder being constituted by a hollow cylindrical body of insulating material, of internal diameter corresponding to the exterior of the bushing and on whose inner surface two metallic sheets to which the conductors of the line are connected are arranged longitudinally and in diametrically opposed positions.
