摘要： An electrical device assembly and method to attach an isolated single stud fuse assembly to an electrical device are disclosed. The electrical device assembly consists of multiple studs, one or more of which is replaced with the isolated single stud fuse. A conductive copper landing zone receives an electrically isolated steel stud. When the landing pad assembly is orbital riveted into a plastic housing of the electrical device, the stud is locked into the housing permanently. Electrical devices such as disconnect switches and power distribution modules, both of which include multiple studs, are good candidates for being adapted with the single stud fuse assembly.

摘要： A single bolt fuse assembly and method to connect a single bolt fuse to a circuit or device are disclosed. The single bolt fuse assembly enables the single bolt fuse to be used on any electrical device having a hole suitable for receiving a threaded shaft and connectable to a circuit or device that electrically connects to a female battery or power cable. The apparatus includes a separate high-conductive metal terminal that mates with the stud that mechanically attaches the fuse between the electrical devices. The stud is insulated to avoid becoming part of the electrical circuit and to ensure proper operation of the fuse. By mechanically attaching the stud to the metal terminal, the stud is unlikely to get separated from the fuse.

摘要： To provide a protecting device and a battery pack using the same, which are less likely to cause a spark even when a high voltage is applied and can safely and quickly interrupt the current path. A protecting device includes: an insulating substrate 2; a fuse element 3; a heat-generator 4 which generates heat to blow the fuse element 3; a heat-generator feeding electrode 5 which serves as a power-feeding terminal to the heat-generator 4; an insulating layer 6 which covers the heat-generator 4; and a heat-generator lead-out electrode 7 which is formed along the heat-generator 4 on the insulating layer 6 and holds the melted conductor 3a of the fuse element 3, wherein, when the heat-generator 4 is energized, the heat-generator feeding electrode 5 side thereof works as a high potential portion and the heat-generator lead-out electrode 7 side thereof works as a low potential portion, and in the heat-generator lead-out electrode 7, an overlapping area in which a distal end portion 7a extending in the high potential portion side of the heat-generator 4 overlaps the heat-generator 4 is smaller than an overlapping area in which a proximal end portion 7b extending in the low potential portion side of heat-generator 4 overlaps the heat-generator 4.
