ABSTRACT:
A fuse includes at least one ceramic part at least partially surrounded by a sinterable mass coating that is electrically conductive after a sintering process. The sinterable mass coating is disposed in the vicinity of the two remote sides of the first part. The fuse also includes a second part firmly connected to the first part by the mass coating. The second part has an electrically conductive surface and a fuse element. A method for manufacturing a blowout fuse includes fixing a first part of the fuse made from metal or a ceramic material to a second part of the fuse made from metal or a ceramic material using a sinterable mass. This method includes the steps of applying a mass to be fixed by sintering to at least one portion of the surface of the first part and/or one portion of the surface of the second part. The mass acts as an intermediate layer between the two parts to be connected and wholly or partially covers both surfaces. In a heat treatment suitable for sintering, the mass is firmly connected to the portions of the surfaces of the parts to which they are applied.
