angeordneten Schmelzleiter 2 eingebaut. An den Stirnseiten am Isolierstüek sind die plattenfärmigen Anschlusstücke 4 aufgeklemmt. Diese Anschlusstücke weisen Umbördelungen 4a auf, welche an ihren Rändern in Auskerbungen 5 des Isolierleitera eingerollt sind. Das Anschlusstück und die Umbördelung wird vorteilhaft aus einem Stück gepresst. Die Anschlusstücke weisen Andrehungen 4b auf innerhalb welchen die umgelegten Enden der Schmelzleiter radial angeschweisst oder angelötet sind·arranged fusible conductor 2 installed. The plate-like connection pieces 4 are on the end faces of the insulating piece clamped. These connecting pieces have flanges 4a, which at their edges in notches 5 of the Isolierleitera are curled up. The connection piece and the flange are advantageously pressed from one piece. The connecting pieces have turns 4b within which the folded ends of the fusible conductors are radially welded or soldered are·

Gegen aussen ist der Raum mit den Schmelzleitern der mit Quarzsand ausgefüllt ist und beim Schmelzen der Sicherung einem Ueberdruck ausgesetzt ist, durch einen aufschraubbaren Deckel 6 abgeschlossen·Outside the room with the fusible conductors is the one with Quartz sand is filled and the fuse is exposed to excess pressure when it melts, through a screwable Cover 6 completed

Der Vorteil der erfindungsgemässen Sicherung besteht darin, dass zwischen Anschlusatück und Schmelzleiter infolge des Schweissens oder Lötens keinen Uebergangswiderstand vorhanden ist der, wie bei Schraubenverbindungen druckabhängig sein kann. Dadurch werden zusätzliche Spannungsabfalle die zudem noch sehr unterschiedlich sein können und zusätzliche Erwärmung ergeben t vermieden. Die einzigen möglichen druckabhängigen Kontakte beschränken sich auf den Anschluss der Sicherung wofür Schraubenverbindungen oder Messerkontakte vorgesehen sind. Dadurch, dass die Anschlussplatte mit ihrer Umbördelung, ein durch Pressen herstellbares Stück ist, ergibt sich eine rationelle Herstellungsweiae.The advantage of the fuse according to the invention is that, as a result of the welding or soldering, there is no transition resistance between the connection piece and the fusible link, which, as in the case of screw connections, can be pressure-dependent. This will additional voltage drops which in addition can be very different and additional heating resulting t avoided. The only possible pressure-dependent contacts are limited to the connection of the fuse, for which screw connections or blade contacts are provided. The fact that the connection plate with its flanged edge is a piece that can be produced by pressing results in an efficient production method.

Die Sicherung findet vor allem Anwendung in Halbleitergleichrichteranlagen. Dort wird jeder Gleichrichterzelle eine solche Sicherung vorgeschaltet, wo es sehr wichtig ist, dass minimalste und gleichmässige Widerstandswerte erreicht werden.The fuse is mainly used in semiconductor rectifier systems. Such a fuse is connected upstream of each rectifier cell, where it is very important that achieves minimal and uniform resistance values will.
