A fuse includes a case member that has a rectangular parallelepiped shape and has a space, a lid member that closes an upper opening of the case member and closely adheres to the case member, a fuse-element disposed in the space, and a pair of terminals, whose distal ends are exposed to outside, connected to both ends of the fuse-element. The case member includes a plurality of first engaging projections formed on a first side wall, and a plurality of second engaging projections formed on a second side wall. The lid member includes a plurality of first engagement recesses formed in a first contact wall and fitted respectively to the plurality of first engaging projections, and a plurality of second engagement recesses formed in a second contact wall and fitted respectively to the plurality of second engaging projections.

A fuse includes multiple stacked layers, a first terminal, and a second terminal. The first terminal is connected to one end of a fusible element and the second terminal is connected to the other end. The stacked layers include first and second intermediate layers and a special layer. The first intermediate layer, which has a centrally disposed opening, is stacked on the first terminal and the second terminal. The second intermediate layer, also having a centrally disposed opening is stacked above the first intermediate layer, and the centrally disposed openings define a chamber above the fusible element. The special layer is located between the first intermediate layer and the second intermediate layer and includes one or more geometric elements. The geometric elements divide the chamber into two sub-chambers, the first sub-chamber being above the second sub-chamber.

A reflowable thermal fuse including a fuse body, a conductive composite element disposed within the fuse body, first and second conductive terminals connected to the conductive composite element and extending out of the fuse body, a removable barrier covering a surface of the conductive composite element and in electrical communication with the first and second conductive terminals, and a solvent element disposed on the removable barrier and separated from the conductive composite element by the removable barrier, wherein the removable barrier has a fusing temperature that is greater than a reflow temperature of the reflowable thermal fuse.

Approaches herein provide a fuse assembly including a multi-part symmetrical housing. In some embodiments, the fuse assembly includes a core having a set of fusible elements extending between a first end fitting and a second end fitting, and a housing surrounding the core. The housing may include a first section having a first wall defining a first internal cavity, the first wall including a first slot and a first ridge, and a second section coupled to the first section, the second section having a second wall defining a second internal cavity. The second wall may include a second slot and a second ridge, wherein the first slot engages the second ridge and the second slot engages the first ridge. In some embodiments, the first and second sections define a set of openings for the first and second end fittings to extend therethrough.

A compact, high breaking capacity fuse that includes a top and bottom insulative layer and a single piece fusible element disposed between the top and bottom insulative layer. The top and bottom insulative layers include cavities that are aligned at assembly to form a chamber in which a fusible element portion of the single piece fusible element is disposed. The single piece fusible element additionally includes terminal portions that extend along outer surfaces of the top and bottom insulative layers.

The subsea fuse assembly includes an enclosure filled with a dielectric fluid and provided with an equalization opening, which is sealed with a flexible element. A first electric conductor extends into the enclosure through a first lead-through positioned in a wall of the enclosure. A second electric conductor is attached to an inner surface of a wall of the enclosure. A fuse is connected between the first electric conductor and the second electric conductor within the enclosure. A third electric conductor extends outside the enclosure and is attached to an outer surface of a wall of the enclosure. An electrically conductive path is thus provided between the second electric conductor and the third electric conductor through the electrically conductive enclosure.

A lightweight industrial fuse has a housing and a conductive fuse. The housing has a first plastic half-housing and a second half-housing combined with each other. The conductive fuse is integrally formed and clamped between the first and second half-housing. The conductive fuse has a fusible body and two intermediary portions disposed within the housing, and two electrode portions exposed from two opposite ends of the housing. Thus, an enclosed accommodation cavity of the housing is defined through the combination of the first and second half-housing. A manufacturing process is simplified, and a manufacturing cost is decreased, and further a weight of the industrial fuse is effectively reduced.

The present invention provides a multi-link fuse capable of charging a battery with a configuration simpler than a conventional configuration, and a method for charging a battery by using the multi-link fuse. A multi-link fuse H includes a bus bar body that includes an input terminal, a plurality of external terminals, and a fusion portion provided between the input terminal and the external terminal, and a housing body that covers the bus bar body. The multi-link fuse H includes an extension bus bar for charging a battery by connecting a charging connection terminal. The extension bus bar includes an input extension terminal that overlaps the input terminal and an outer extension portion that extends outward from the bus bar body and connects the charging connection terminal. Both the extension bus bar and the bus bar body are fixed to the housing body in a state where the input extension terminal of the extension bus bar overlaps the input terminal.
