  • Publication number: 20090189730
    Abstract: A fuse is disclosed, the fuse made of a first metal, such as copper, and having a notched portion with an alloying element, such as tin, deposited in the notch. The alloying element helps to lower the voltage drop across the notch, allowing the fuse to generate less heat during operation without affecting its ability to protect a circuit to which it is connected. The fuse may also include a housing and terminals to connect into a circuit.

An element 3 is securely held between the two lengthwise ends of a tubular fuse casing 2 and a pair of metal plates 4 having a melting point of more than 1000° C. The ends of the fuse casing 5 are respectively pushed into caps 5 so that the caps are fitted to the fuse casing 2 in such a manner as to cover the metal plates 4. The metal plates 4 protect the caps 5 from direct exposure to an arc discharge, which occurs when the element 3 fuses due to an overcurrent. Even if the fuse casing is made small, the metal plates 4 reliably interrupt overcurrent by absorbing the energy of an arc discharge.

  • Patent number: 6710696
    Abstract: An improved fuse housing includes a main body and a cover and is configured to receive a fuse. The main body includes a plurality of fins that are configured to increase the surface area of the fuse housing in order to enhance heat dissipation. The main body is formed with a cavity for the fuse and a pair of conductors extending between the interior of the fuse housing and the exterior thereof for connection with the fuse. The cavity is configured to minimize the quantity of air between the fuse and the fuse housing to facilitates heat transfer. Each conductor includes excess studs for connection with the fuse to enhance heat conduction from the fuse. The cover is fastened to the main body with sufficient fasteners to permit the cover to be a stressed member to resist fracturing of the fuse housing from magnetic and other forces from the conductors.
