Abstract

La résistance selon l'invention comprend une fine feuille de résistance collée à un substrat rigide beaucoup plus épais, avec un trajet résistif entre des patins d'extrémités défini dans la feuille. Elle comprend en outre, à l'intérieur des limites de chaque patin, au moins une ouverture qui traverse l'épaisseur totale de la feuille et un conducteur de connexion plat en cuivre reposant sur et couvrant une partie de chaque patin et soudé par points à la feuille du patin. Les problèmes de soulèvement des patins à l'écartement du substrat à la suite de la constitution par soudure par points de la résistance sont élimintés.The resistor according to the invention comprises a thin resistor sheet bonded to a much thicker rigid substrate, with a resistive path between end pads defined in the sheet. It further comprises, within the boundaries of each pad, at least one opening which passes through the full thickness of the foil and a flat copper connecting conductor resting on and covering a portion of each pad and spot-welded to the sheet of the skate. The problems of lifting the pads away from the substrate as a result of the resistance spot welding is eliminated.
