Abstract

Lampholder perfected, which is characterized by the upper neck that has the metal dome cap where the bulb is screwed, is located a fitting, whose outer contour offers a pair of projections arranged diametrically opposite, as well as a pair of cavities, which likewise, the coupling is immobilized by adapting to the said protrusions and hollows, by means of the appropriate deformation, the wall of said coupling a hollow stud, whose penetration is limited by one or several deformations made in the lower edge of the fitting and which they affect the filleting of the same, constituting itself as a stop, while in one of the projections that has the outer contour of the fitting, an oblique threaded hole is provided where a screw is located, whose end impinges on the threaded contour of the asparagus previously alluded, therefore, preventing the rotation of the dome cap, while, on the other hand, the lower edge the upper part of the fitting has two descending wings in diametrical opposition, which have been designed so that it can slide along a guide occupying a certain position, being in said position that the cavities made in its outer contour are faced with respect to punches belonging to a clamping device, which makes it possible for the wall of the neck of the dome or socket of the lamp holder to be inserted into said recesses.
