  • 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.

  • Publication number: 20120044038
    Abstract: Disclosed are a small fuse and a method of manufacturing the same. A cover made from thermosetting resin is coupled with is a base to receive a fusing element therein. The fusing element does not cause damage to the cover even if the fusing element makes contact with an inner wall of the cover due to size reduction of the cover.

  • Publication number: 20120032774
    Abstract: Disclosed are a thermal fuse resistor having a case injection-molded by using thermosetting resin having heat resistance less than that of 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, even if the case has a lighter weight and a thinner thickness by changing the material of the case as compared with those of a case according to the related art, the case is not easily broken, so that the case is suitable for the lightness and slimness of an electronic appliance employing the thermal fuse resistor. Since only the thickness of the case of the thermal fuse resistor is reflected to the thickness of the electronic appliance employing the thermal fuse resistor, the thermal fuse resistor is suitable for the slimness of the electronic appliance.

  • Publication number: 20100060406
    Abstract: A small-sized surface-mounted fuse and a method of manufacturing the same. A fusing element, separated from a winding member, is connected to lead wires by arc welding instead of soldering. Consequently, the present invention has the effect of improving fusing characteristics and productivity while reducing the defective rate and manufacturing costs.

  • Patent number: 7221253
    Abstract: A fusible resistor and method of fabricating the same is provided. The fusible resistor has a very low resistance of 20 to 470 m?. by depositing thin films as a fusible element made of a material with low resistivity such as copper having a temperature coefficient of over 2,000 ppm/° C. The fusible resistor comprises a resistor body, a fusible element layer formed to surround the resistor body, caps formed to surround ends of the fusible element layer, lead wires attached to the caps, and an insulating layer for insulating the fusible element layer and the caps from outside. The thus-fabricated fusible resistor performs all functions of a use without generating excessive heat.
