ABSTRACT:
The socket member for electrical connectors is obtained thanks to permanent deformation by twisting of a cylindrical sleeve of suitable metal, provided with through slots (2) arranged on its cylindrical surface and inclined with respect to the longitudinal axis of the sleeve. Each slot, previously to its twisting deformation, presents a transverse profile with sides (102, 202) diverging towards the exterior, and said sides meet at the ends of the slot forming curvilinear edges (302, 402) in such a manner that the vertices of said edges located on the inner surface of the sleeve are nearer to each other with respect to the vertices of the edges located on the outer surface, which are farther from each other. The particular shape of the slots contributes in a determining manner to the correct deformation upon twisting of the sleeve, so that the strips defined by the slots tend to be arranged according to a family of straight generatrices of a hyperboloid of one sheet, taking in consideration the composite stresses of traction-compression and torsion which take place precisely upon twisting of the sleeve. In this manner there is avoided the formation of irregularities, such as sharp edges or warped surfaces, in the areas of contact at the interior of the thus formed socket.
