Verfahren zum Anschweissen eines flexiblen Leiters an einen Kontaktfinger, und Kontaktfinger.

摘要

Method for making a welded connection between a braid (20) and a contact finger (10) comprising two elementary thin plates (12, 14) stacked face to face. The first thin plate (12) is provided with a half-open recess (24) interacting with the juxtaposed plane face of the second thin plate (14) in order to define a housing (25) for accommodating one compacted end (21) of the braid (20), the said end undergoing hot incrustation in the housing (25) by means of pressure welding, without local deformation of the thin plates (12, 14). The second thin plate (14) comprises a backflow opening (26) disposed at right angles to the recess (24) for allowing transfer of molten copper during the welding operation, the surface of the opening (26) being less than that of the recess (24). The connection is carried out in a single operation without braze feed. ……
