Abstract
An electrical fuse having an insulator, through which a cavity extends from one end to the facing end and which has a cross-sectionally square or rectangular casing part, is further developed in such a way that in the case of easy manufacture a reliable sealing of the cavity openings and a reliable fixing of the fuse element ends, as well as the connections or terminals to the end portions of the insulator are ensured, particularly in such a way that connections projecting over the insulator profile are avoided. For this purpose the insulator has on at least one side an offset end portion of constant cross-section. The fuse is in each case provided with a solder coating at least covering the ends of the end portions, has electrical connections and also a fuse element, which passes through the cavity and whose ends are in each case conductively connected to the electrical connections. There is also a metal coating, which is directly applied in firmly adhering manner at least to the ends of the end portions of the insulator and to which is fixed the solder coating.
