1. A method of manufacturing an electrical power contact for the passage of direct currents greater than 10 Amps, consisting of two separate solid conductive parts made from metal, namely a connecting part and a connection terminal for connecting the electrical power contact to a conductor, a first of the two conductive parts being provided with a shoulder and a protruding portion with respect to the shoulder, a second of the two conductive parts comprising a wall having a bearing face bearing against the shoulder and a free face opposite the bearing face, the wall being passed through by a cylindrical through-hole having an open end on the bearing face and an opposite end open on a counterbore constituting a recess in the free face, the protruding portion passing through the cylindrical through-hole, wherein the protruding portion has a flared free end forming a head housed in the counterbore, the head having a cross-section greater than a passage section of the cylindrical through-hole, forming a connection that cannot be disassembled between the two conductive parts, and the counterbore comprising a frustoconical face directly adjacent to the cylindrical through-hole, the method of manufacturing comprising:
forming the head by cold deformation, that provides a contact interface between the head and the counterbore without welding or brazing.
