Abstract

Ein Schmelzleiter für einen elektrischen Sicherungseinsatz enthält einen bandförmigen Grundkörper (2), der mit zumindest einem Verengungsbereich (4) versehen ist. Gemäß der Erfindung nimmt der Grundkörper (2) in einem zumindest an den Verengungsbereich (4) angrenzenden Lotbereich einen Lotauftrag (8) auf, wobei auf der Lotseite des Grundkörpers (2) eine an den Verengungsbereich (4) zumindest angrenzende erste Lotstopschicht (10) versehen ist. Dadurch ist im Ansprechfall des Sicherungseinsatzes ein unkontrolliertes Verlaufen leicht verlaufender Lote über den Verengungsbereich (4) des Schmelzleiters hinweg vermieden, die Reproduzierbarkeit des Abschaltverhaltens des Sicherungseinsatzes gewährleistet und dessen Funktionstüchtigkeit sichergestellt.

Figure 00000001
A fuse element for an electrical fuse link contains a band-shaped base body (2) which is provided with at least one constriction area (4). According to the invention, the base body (2) receives a solder application (8) in a solder area at least adjacent to the constriction area (4), a first solder stop layer (10) at least adjacent to the constriction area (4) on the solder side of the base body (2). is provided. As a result, when the fuse link responds, uncontrolled running of easy-running solders over the constriction area (4) of the fuse element is avoided, the reproducibility of the switch-off behavior of the fuse link is guaranteed and its functionality is ensured.
