ABSTRACT:
A connection process by welding a braided strip to a contact finger defined by side by side stacking of two elementary blades. The first blade is provided with a semi-open notch cooperating with the juxtaposed flat face of the second blade to define a housing receiving a compacted end of the braided strip, said end being hot encrusted in the housing by welding under pressure, without local deformation of the blades. The second blade comprises an overspill aperture located facing the notch to enable the molten copper from the compacted end to be transferred during the welding operation, the surface of the aperture being smaller than that of the notch. Assembly is performed in a single operation without addition of solder.
