摘要

Protective chain perfected conductive cables and the like, of which they are constituted by a series of pairs of links related to each other, by some reinforcement dice, characterized because their links are formed by two plates, each one of them conforms in reciprocal symmetry and in one from its ends a protrusion, which is provided with an anchor hole and is escorted by two guide recesses, while, at the other end, each of said sheets forms an outward drawing whose surface presents an arched finish. Circumferential at the end, an anchor hole in its central part and paths inside it, in the subsequent confrontation of both semi-links, which give direct contact and can be rigidly joined by riveting or similar, giving place to a plate cavity that is constituted in the accommodation for the other end of the old link; so that, once the anchorage between links is secured by means of a rivet pin that penetrates in both opposing anchoring holes or any analogous solution, the riveted constructions are positioned in the guide recesses, of the adjacent link, thus establishing both embossments in their conjunction with the guide recesses, a perfect guiding action in the inter-link angular displacement, at the same time that the action of one of them delimits this turn in one direction, while the other prevents the turn in the opposite direction and beyond of the alignment between links.
