Abstract (en)
An electric conductor assembly comprising: an electrically conductive contact having a i constituent comprising a non-alloying material and further comprising silver; and an electrically conductive contact carrier comprising a predominance by weight of nonferrous material, mechanically joined together at a particular location by the application of ultrasonic energy, brazing material being disposed between the contact and the carrier at the location where they are joined. The brazing material comprises at least two materials, with elemental copper being the largest single constituent of the brazing material, and the contact comprises serrations in the surface joined to the brazing material, said serrations being filled with excess silver from the contact, the brazing material forming a layer overlapping the serrations. <IMAGE>
