    Abstract: A fuse holder, particularly for interlocked sockets and electrical apparatuses in general, includes a tray which is inserted in a seat and is adapted to accommodate a fuse. The tray is movable along a rectilinear path, having at least two positions: an active position, in which the fuse is active, and an extracted position, in which the fuse can be removed from the tray. The seat includes two elastic contact members which provide an electrical and mechanical connection of the fuse in the active position.

  • Patent number: 8593790
    Abstract: A device and method of use of a multiple discharge panel for a multiple-discharge, high energy electric device. The device generally uses a panel for a multiple-discharge, high energy electric device that includes a plurality of fuse assemblies constructed in a cascading arrangement in a common panel. Each fuse assembly provides protection from a single high energy discharge pulse and includes a structure defining a cavity. The fuse assembly further contains a resistor made of components that explode when subjected to a large pulse of power to temporarily interrupt and dissipate the large pulse of power. The structure defining the cavity is shaped to deform in response to explosion of the resistor such that a new connection to a remaining one of the plurality of fuse assemblies is established.

  • Patent number: 8547195
    Abstract: A protection element and a secondary battery device employing the protection element are provided for stably retaining a flux on a soluble conductor at a predetermined position, so as to enable appropriate blowout of the soluble conductor in the event of an abnormality. The protection element has a soluble conductor which is disposed on an insulation baseboard, and which is connected to a power supply path of a device targeted to be protected, and which causes a blowout when a predetermined abnormal electric power amount is supplied. A flux is coated on a surface of the soluble conductor, and an insulation cover member is mounted on the baseboard and covers the soluble conductor. The protection element also includes a stepped portion for retaining the flux at a predetermined position in contact with the flux, and the stepped portion is formed opposite to the soluble conductor on an interior face of the insulation cover member.

  • Publication number: 20130200984
    Abstract: A circuit protection device includes a substrate with first and second electrodes connected to the circuit to be protected. The circuit protection device also includes a heater element. A sensing element facilitates an electrical connection between the first and second electrodes. A flux material is provided around the sensing element. In a preferred embodiment, the flux contains a first component that is a polar material and a second component that is a non-polar material. A spring element exerts a force on the sensing element. The sensing element resists the force applied by the spring element. Upon detection of an activation, or fault, condition, the sensing element loses resilience and no longer resists the force exerted by the spring element, resulting in the spring element severing the electrical connection between the first and second electrodes. The flux allows the spring element to sever with electrical connection without dragging the sensing element.

  • Patent number: 8400252
    Abstract: Disclosed is a fuse resistor representing superior manufacturing efficiency and assembling reliability. The fuse resistor includes a resistor, a thermal fuse that is disconnected by heat generated from the resistor, and a case receiving the resistor and the thermal fuse therein and having a space section for transferring radiant heat of the resistor to the thermal fuse. Fillers are not required so that the manufacturing process is simplified. Since the assembling process is completed by covering a body of the case with a cap after the resistor and the thermal fuse have been inserted into the body, the manufacturing efficiency is improved.

  • Patent number: 8400253
    Abstract: Disclosed are a thermal fuse resistor having a case injection-molded by using thermosetting resin having heat resistance less than that of a filler, a manufacturing method of the thermal fuse resistor, and a method of installing the thermal fuse resistor such that a resistor and a thermal fuse are laid down on a printed circuit board. In the thermal fuse resistor, through changing a material of the case, the case has a lighter weight and is not easily broken, so that the thermal fuse resistor is advantageously used for an electronic appliance because of its lightness and slimness. The thickness of the case of the thermal fuse resistor serves as the thickness of the electronic appliance employing the thermal fuse resistor, so that the thermal fuse resistor allows the electronic appliance to have a slim structure.
