  • Patent number: 6272000
    Abstract: A fuse includes a housing and terminal blades extending therefrom. Each terminal blade includes a stop face, a stop brace, a hold face, and a hold brace. The stop face and stop brace prevent over insertion of the terminal blade through a circuit board and separate the fuse housing from the circuit board. The stop brace and hold brace position the housing relative to the board and prevent dislodging of the blades from the board during soldering operations.

  • Patent number: 5235306
    Abstract: The improved fuse assembly includes a trigger assembly having an electrically nonconductive barrel for receiving a spring loaded trigger therein and a heater strip disposed along the outer circumferential surface of the barrel with a pair of end flaps. One end flap has a hole therethrough which fits over the end of the trigger adjacent the short circuit element. A second flap fits over the end of the barrel adjacent the end ferrule. The short circuit element, which is electrically and mechanically linked to a ferrule on the opposite end of the tube from the trigger assembly, engages the trigger and heater element in a solder fusing alloy.

  • Patent number: 4517544
    Abstract: A time delay fuse includes a tubular housing of insulative material with first and second open ends. First and second metallic or electrically conductive ferrules are mounted on the first and second ends, respectively, of the tubular housing. A core is positioned within the tubular housing and affixed to the ferrules by electrically conductive material such as solder. At least one short inner wire extends along the core and is electrically and mechanically connected to the solder. A second wire, longer than the first wire, is spirally wound around the core and the first inner wire. The second wire includes first and second ends mechanically and electrically connected to the conductive material such that the first and second wires are electrically parallel.

  • Patent number: RE33137
    Abstract: A subminiature fuse is disclosed comprising two terminals, a substrate, a fusible conductor, and a unitary housing. The unitary housing is sealed and provides increased mechanical strength, thus reducing the risk of a catastrophic failure of the fuse. The upper portion of the fuse terminals are shaped into finger like projections adaptable to mechanically fastening the fusible conductor and the substrate thereto thus facilitating the manufacturing process. In one embodiment the fusible conductor and adjacent portions of the terminals and substrate are coated with a ceramic coating or adhesive. The housing is sealed by utrasonic welding or preferably in an insert molded plastic enclosure which is substantially devoid of air.
