  • Publication number: 20070236323
    Abstract: A fusible conductor for a fuse element includes an electrically insulating core a fusible wire wound about the core and at least one electrically insulating fiber wound about the core parallel to the fusible wire such that the fusible wire is fixed in position so that a short circuit of adjacent turns of the fusible wire is prevented.

  • Patent number: 7265653
    Abstract: The invention relates to a method for producing a protective component, for example a fuse component or a fusing resistor, including a fusible element and a heating element, which are attached as stacking components to the surface of a substrate. The fusible element is configured in such a way that a current flow between its connections is interrupted, if the fusible component is heated, at least in one fusible region, for a predetermined time period to above a predetermined temperature. The fusible element and the heating element are arranged on the substrate in such a way, that heat created by the heating element is transported to the fusible element and the current flow through the heating element exceeds a threshold value for a predetermined time period. During production, the heating element is positioned next to the fusible element, at a predetermined distance from it.

  • Publication number: 20070132539
    Abstract: A fusible spiral conductor for a fuse component includes an electrically insulating or high resistance core, at least one fusible conductive wire wound around the core, and a temperature-resistant plastic material. The temperature-resistant plastic material applied to the core and arranged such that at least the surface regions of the core exposed between the fusible conductive wire are covered by the plastic material and the interstices defined between the wound fusible conductive wire and the surface of the core are substantially filled with the plastic material.

  • Patent number: 6384708
    Abstract: An electrical fuse element (1), which comprises a substrate (4) with two contacts (2) arranged on opposite end sides (3), terminal areas (7) connected to the contacts and a fusible conductor (10) electrically connected in a conducting manner to the contacts via the terminal areas, is developed for use in higher voltage ranges, with improved breaking capacity and with low production costs, by the terminal areas (7) and the fusible conductor (10) being arranged separated from one another by an insulator (4) and electrically connected to one another via lead-throughs.

  • 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.
