20090066469 | BATTERY FUSE ASSEMBLY - A fuse includes a fusible element and a body member encased within a heat-resistant housing. The fusible element is configured to open an electrical circuit coupled to a storage battery in response to an over-current in the electrical circuit. The housing is configured to contain an arc generated by the fusible element in response to the over-current and to shield the arc and the fusible element from ambient particles. Thus, the fuse is ignition protected. The body member includes an insulating material configured to interrupt the arc. The housing includes an opening configured to receive a terminal of the storage battery or a terminal of a mounting plate. An insulating material disposed about a first end of the mounting plate terminal is configured to electrically isolate the fuse and a power supply cable in the electrical circuit from the mounting plate terminal. | 03-12-2009 |

20100164677 | FUSE - A fuse has a base and multiple wires. The base is an insulator and has a top surface and multiple contact plates. The contact plates are mounted separately on the top surface of the base. The wires are high density conductive alloy including Al 60˜90 wt %, Mg 22˜30 wt %, Si 1˜3 wt % and Cu 1˜3 wt % and connect the contact plates in series. Since the wires are directly heated, response time, sensitivity, power waste and heating resistor damage problems are solved and because the wires are high density conductive alloy that is nearly independent of environmental temperature, the temperature dependency, installation position limitation and leakage current problems are also solved. | 07-01-2010 |
20100207716 | Overcurrent protection structure and method and apparatus for making the same - The overcurrent protection structure according to the present invention mainly comprises a fusible fuse structure unit disposed in a coating, and the both ends of the fusible fuse structure unit extend outwardly beyond the coating and form a first electrode and a second electrode. In the manufacturing process, the gas-assisted injection molding process enables at least one space for accommodating gas disposed between the fusible fuse structure unit and the coating such that the heat generated by the electrically energized the fusible fuse structure unit will not dissipate through the heat conduction of the coating in order to ensure that it will blow at high temperature when reaching a specific current or a specific temperature and the circuit protection effect. | 08-19-2010 |
20100245022 | Electrically activated surface mount thermal fuse - A reflowable thermal fuse includes a conduction element with first and second ends, disposed within a housing. The reflowable thermal fuse also includes an elastic element disposed within the housing and adapted to apply force on the conduction element in an activated state of the reflowable thermal fuse. A restraining element is utilized to secure the elastic element and prevent the elastic element from applying force on the conduction element in an installation state of the reflowable thermal fuse. Application of an activating current through the restraining element causes the restraining element to break and thereby release the elastic element and place the reflowable thermal fuse in the activated state. | 09-30-2010 |
20160064173 | FUSE FOR HIGH-VOLTAGE APPLICATIONS - A current-limiting fuse for use at voltages between 23 kilovolts (kV) and 38 kV includes a body including a sidewall that at least partially defines an interior space; a fuse element in the interior space of the body, the fuse element wrapped around a non-conductive core and connected to first and second electrically conductive plates; and a non-bound particulate material in the interior space of the body, the non-bound particulate material including a plurality of pieces of the material with voids between at least some of the pieces. A fuse holder for use at voltages between 23 kV and 38 kV includes a housing for insertion in a sidewall of a transformer. The housing includes an exterior surface that defines an interior region. A fuse assembly is received in the interior region of the housing, the fuse assembly being configured to be replaced without opening the tank of the transformer. | 03-03-2016 |
20160133423 | FUSE LINK - A fuse link used in alternate current medium- or high-voltage systems with a current frequency of 50 Hz includes a spring-type striker pin and is designed for the protection of electrical devices against consequences of short circuits and overloads. A porcelain housing with a star-core, external end caps closed by plugs, star-core end caps with a ring-shaped first tap designed to ensure electric contact between the star-core end cap and the external end cap of the fuse link is also included. A spring-type striker pin is positioned along the axis of the star-core. Each of the end caps of the star-core is provided with an additional second tap designed to centre the star-core relative to the axis of the fuse link. The spring-type striker pin is centred along the longitudinal axis of the fuse link. | 05-12-2016 |
20160189905 | Protection Device Employing Current Limiting Fuse and Vacuum Fuse - A non-current limiting vacuum fuse employs a fusible assembly having a pair of electrodes and a fusible element that is situated therebetween. The fusible assembly is a rigid, self-supporting unitary structure that is brazed to an envelope when manufactured inside a vacuum furnace. The fuse provides improved interruption capability and/or a higher voltage rating at reduced cost. The fuse may be used individually, or a plurality of the fuses can be connected together in series to provide enhanced interruption capability and/or a higher voltage rating. The fuse can be connected in parallel with a current limiting fuse to form a vacuum current commutating fuse that provides the benefits of both types of fuses. | 06-30-2016 |
