1. A method of crimping an electrical contact having a closed-section barrel, which is initially generally convex in shape, onto a cable with multiple conducting strands in order to produce a crimped assembly, wherein the barrel is crimped by deforming a section of the barrel from the initially generally convex shape to a final crimped shape in which the section is compression-necked onto the strands of the cable in such a way that a first portion of the section has, in its thickness, at least two adjacent indentations, said method comprising succesive steps of:
inserting an end of the cable to be crimped into the barrel of the contact;
compression-necking the barrel onto the cable by a die stamping operation so as to impart to the barrel an intermediate necked form that is generally convex in cross section, and
a punching operation, to form the indentations in the barrel, said punching operation being performed after the die stamping operation.
