Abstract
An electrical component, particularly a fuse for a surface-mount component, is formed by sputtering an aluminum conductor onto a square tube, sleeving the tube into an outer tube, filling the assembly with a room-temperature vulcanizing silicone sealant, cutting the assembly into segments, and metallizing the ends of each segment. In one embodiment, the sleeved tubes are mechanically separated from the surrounding silicone. In another embodiment, the silicone-coated tubes are mechanically separated from the outer tubes. In another embodiment fuses are made by sputtering the conductors onto a thin glass substrate, covering a link portion of the conductors with silicone adhesive, and dicing the substrate.
Claims20
An electric fuse comprising a dielectric sheet having a broad face with a length and breadth, the sheet having a thickness much less than either the length or breadth, an electrical conductor on the broad face of the sheet, the conductor including a fusible link, and a dielectric synthetic polymer adhesive over the link, the adhesive bonding to the link and to the sheet.
An overcurrent protective fuse comprising a conductor including a fusible link part, the conductor being metallized onto a dielectric sheet having a broad face with a length and breadth, the sheet having a thickness much less than either the length or breadth, the conductor being metallized onto the broad face of the dielectric sheet, the fusible link part consisting essentially of a material selected from the group consisting of aluminum and aluminum alloys, and a coating of silicone elastomer in contact with the link part.
An electric fuse comprising a dielectric substrate, an electrical conductor on the substrate, the conductor including a fusible link, and a dielectric synthetic polymer adhesive over the link, the adhesive bonding to the link and to the substrate, the adhesive being the sole barrier between the link and ambient.
