  • Patent number: 10158203
    Abstract: A fusible conductive material can be used to electrically connect or join power distribution bus bars that are placed on opposing sides of an electrically insulating bus support. The fusible conductive material can be placed in an opening or hole in the bus support with the bus bars abutting the fusible conductive material on opposing sides. The fusible conductive material can then be ignited, such as by applying a voltage drop, to produce a localized heat source suitable to electrically join the bus bars together. By electrically connecting the bus bars in this manner, the bus bars can better conduct, be less susceptible to separation and require less maintenance with respect to connectivity.

The electrical conductive terminal includes conductive pieces for allowing the pins to be inserted therein and a connecting arm for connecting the conductive pieces. The conductive pieces are arranged to correspond to the through holes. The insulator is fixed to the connecting arm. The light-emitting unit is provided between the insulator and the casing and is electrically connected with the conductive pieces. When the current is overloaded, the connecting arm will be melted to break, so that the light-emitting unit will be lighted up to generate an indicating effect.

  • Patent number: 7663466
    Abstract: A fuse device for fitting over and around a corner of a battery housing has a top wall and two side walls extending downward from the top wall. The side walls are joined at a corner. A battery terminal for mechanical and electrical attachment to a battery post is provided in the top wall. Electrical connectors for connection to terminals on the ends of electrical cables are mounted on the side walls of the fuse device. The electrical connectors are linked through the walls to the battery terminal by fuses. Ribs extending down the side walls from the top wall pass close by each electrical connector to strengthen the structure of the fuse device and prevent rotation of the terminals on the ends of the cables as they are secured to the fuse device. Recessed strengthening ribs in the top wall extend radially outward from the battery terminal.

  • Patent number: 7659804
    Abstract: A fuse for a high voltage/high current application, such as a hydro-electric vehicle (“HEV”) application is provided. The fuse employs a variety of arc quenching features to handle a large amount of arcing energy that is generated when such fuse is opened due to a fuse opening event. In one embodiment, an insulative substrate, such as a melamine substrate, is metallized with a fuse element. The fuse element extends to multiple surfaces of the substrate. A fuse opening portion of the element is located so that the arcing energy is forced to travel along multiple insulative planes, increasing an impedance across the opening of the element and decreasing the likelihood of a sustained arc. Also, the substrate and element are disposed in a sealed housing, which is packed in one embodiment with an arc quenching material, such as sand.

  • Publication number: 20100019879
    Abstract: A fuse module includes a wiring lug. The wiring lug includes a fuse clip member comprising a first pressure plate and a fuse clip, a lug box comprising a second pressure plate, and a securing member operably coupled to the lug box. The securing member operates between a first position and a second position to move the second pressure plate of the lug box with respect to the first pressure plate of the fuse clip member. The first pressure plate and the second pressure plate have a clamping relationship when the securing member is in the first position and have a non-clamping relationship when the securing member is in the second position.

  • Publication number: 20090315664
    Abstract: The present invention relates to a fuse assembly for rapid interruption of a prospective fault current. The fuse assembly includes a plurality of splitter plates. A plurality of foil elements extend between a pair of terminals and are physically supported by the splitter plates. A pair of parallel busbars are in series with the foil elements and generate a magnetic field that is substantially perpendicular to the current flowing in the foil elements. In the presence of a prospective fault current, the foil elements will melt and at arcing inception an electromagnetic force developed as a result of interaction between the magnetic field and the arc current will push the molten foil elements into the splitter plates. This increases the arc length and hence the arc voltage. At least the foil elements and the splitter plates are preferably located in flowing liquid dielectric such as MIDEL 7131, for example.

  • Publication number: 20090040006
    Abstract: A layer of semiconductor material is patterned to form a cathode semiconductor portion, a fuselink semiconductor portion, and an anode semiconductor portion. A first metal layer is deposited on the patterned semiconductor material layer. A dielectric material layer is deposited and lithographically patterned to cover a middle portion of the fuselink, followed by a deposition of a second metal layer. A thin metal semiconductor alloy is formed in the middle of the fuselink and thick metal semiconductor alloy alloys are formed abutting the thin metal semiconductor alloy alloy. The resulting inventive electrical fuse has interfaces at which a thinner metal semiconductor alloy abuts a thicker metal semiconductor alloy in the fuselink. The divergence of electrical current is enhanced at the interfaces due to a sudden change of a cross-sectional area available for current conduction.

  • Publication number: 20090021338
    Abstract: An electrical fuse is formed on a semiconductor substrate and a first dielectric layer is formed over the electrical fuse. At least one opening is formed by lithographic methods and a reactive ion etch in the first dielectric layer down to a top surface of the electrical fuse or down to shallow trench isolation. A second dielectric layer is deposited by a non-conformal deposition. Thickness of the second dielectric layer on the sidewalls of the at least one opening increases with height so that at least one cavity encapsulated by the second dielectric layer is formed in the at least one opening. The at least one cavity provides enhanced thermal isolation of the electrical fuse since the cavity provides superior thermal isolation than a dielectric material.
