Abstract
Organe de contact composé d'une pièce de contact et d'un support. La réunion des deux parties s'effectue au moyen d'une couche en matériau métallique, sous forme de feuille ou de poudre, qui est transformée sous l'effet d'un sondage sous pression par ondes de fréquence acoustique, cette frequence etant choisie entre 50 hertz et 20 kilohertz. Le matériau métallique d'apport est composé en majeure partie d'aluminium Applications aux contacts électriques.Contact member composed of a contact piece and a support. The two parts are brought together by means of a layer of metallic material, in the form of a sheet or powder, which is transformed under the effect of a pressure sounding by acoustic frequency waves, this frequency being chosen between 50 hertz and 20 kilohertz. The metallic filler material is mainly composed of aluminum. Applications to electrical contacts.
