Abstract
A vibration-proof reinforced lampholder, which is essentially characterized by the existence of a cylindrical tubular piece of porcelain or similar material, which has a base or base, as well as a notch diametrically reaching the said bottom, the terminals being arranged , with its screws for the fastening of the flexible, inside the aforementioned notch and diametrically opposed; one of the aforementioned terminals, through a metal piece that is fixed on the bottom by means of a screw and nut, establishes electrical communication with a metal piece forming a spring destined to receive the end of the lamp, while the other terminal, a Through another metal piece, it establishes electrical communication with a leg or fin of a threaded sleeve intended to receive the lamp cap, which sleeve is fixed on the bottom by screws that pass through its two fins and, in that, in said threaded sleeve, notches are provided along which pass wires that, constituting a spring, prevent the unscrewing of the lamp, wires that, by their bent ends, are retained in longitudinal grooves provided in the tubular part cylindrical porcelain or other insulating material.
