Description

Es ist bekannt, auch Feinsicherungen (Glasrohrschmelzeinsätze) mit einem Unterbrechungsmelder zu versehen. Diese Unterbrechungsmelder müssen trotz der kleinen Abmessungen deutlich erkennbar sein, dürfen die Kontaktflächen des Schmelzeinsatzes für den Stromübergang nicht einengen, die Länge des Schmelzeinsatzes nicht verringern und die Verwendbarkeit der Schmelzeinsätze in den dafür üblichen Sicherungshaltern nicht beeinträchtigen. Diese Forderungen werden von den bekannten Bauarten nur teilweise erfüllt.It is known to also use fine fuses (glass tube melting inserts) to be provided with an interruption indicator. These interrupt alarms must despite Due to the small dimensions, the contact surfaces of the fuse link may be clearly recognizable Do not constrict for the current transfer, do not reduce the length of the fuse link and the usability of the fuse links in the usual fuse holders not affect. These requirements are only partially met by the known designs Fulfills.

Die vorliegende Erfiftdung betrifft eine Bauart von Schmelzeinsätzen für Feinsicherungen, die den angegebenen Forderungen voll entspricht. Das Wesentliche der Erfindung besteht darin, daß, wie in der "Zeichnung dargestellt, das Gehäuse des Unterbrechungsmelders r in seinem Durchmesser gegenüber der Metallkappe 2 des Schmelzeinsatzes verjüngt und dieser vorgesetzt ist. Dabei wird der kegelige Übergang zur Verbesserung der Kontaktgabe in dem Sicherungshalter verwendet.The present invention relates to a type of fuse link for microfuses that fully meet the specified requirements. The essentials the invention consists in that, as shown in the "drawing, the housing of the interruption detector r in its diameter compared to the metal cap 2 of the Fusible link tapered and this is set in front. Thereby the tapered transition used to improve the contact in the fuse holder.
