  • Patent number: 6269745
    Abstract: The present invention relates to an electrical fuse element (1) which comprises at least one fusible conductor (3) and a carrier (2). The object is to provide a fuse element (1) for all known tripping characteristics in a cost-effective production technique for the middle and low-current range. Furthermore, by means of a small outer geometry, the fuse element (1) is to be adaptable to modem methods of insertion. The way in which this object is achieved according to the invention is that the carrier (2) consists of a material of poor thermal conduction, in particular of a glass ceramic.

  • Patent number: 5926084
    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.

  • Patent number: 5179436
    Abstract: The invention relates to an electric fuse with a fuse element located in a housing which encases a fuse element chamber. The fuse element melts and thus cuts out the fuse under an overcharge, whereby the temperature and pressure in the interior of the casing will abruptly rise. The housing is provided with a pressure relief means through which at least part of the gas volume can be let off to the outside to prevent the housing from destruction if high internal pressure peak values occur on cutting out the fuse.

  • Patent number: 4862134
    Abstract: An electrical fuse comprises a fusible conductor welded or bonded onto separated contact surfaces. The fusible conductor is coated with a metal, selected solely for optimum welding or bonding to contact zones of the contact surfaces. The metallic coating of the fusible conductor is then removed at the fusible portion of the coated fusible conductor by etching after the fusible conductor is welded or bonded to the contact surfaces the contact zones surrounding the point of contact protected by a resin cover resistant to the etchant. The electrical characteristic of the fuse is thus determined solely by the core wire and its properties. The resin cover in the contact zones is preserved between the fusible conductor and each contact surface for improved safety against cracks or micro-cracks and their possible adverse effects.
