A fuse component (1) has a fuse element (2). The fuse element (2) is located inside an isolating body (3) and the fuse element (2) extends between the two end faces of the isolating body (3). Each of the end faces of the isolating body (3) are closed by electrical conductive end caps (4) and the end caps (4) are in electrical contact with the fuse element (2). The isolating body (3) includes at least two shells (5a, 5b); at least in the region of the end caps (4), and the shells (5a, 5b) in the assembled state form a channel (6) to receive the fuse element (2).

Provided herein are protection devices, such as fuses. In some embodiments, a fuse may include a hollow body having first and second ends, each of the first and second ends having an end surface and a side surface extending from the end surface. The fuse may further include a fusible element disposed within a central cavity of the hollow body, the fusible element extending between the first and second ends. The fuse may further include an inner cap formed over at least one of the first and second ends. The inner cap may include a center portion in contact with the fusible element, and a plurality of spring legs extending from the center portion, wherein the plurality of spring legs is in contact with the side surface of the first and/or second ends. The fuse may further include endcaps surrounding the first and second ends.

Hollow bodies and hollow body fuses are disclosed. Furthermore, methods to provide hollow bodies and hollow body fuses are disclosed. In one implementation, a hollow body includes a center portion and an end portion. An endcap may be coupled to the end portion. A cavity is formed between an inside surface of the endcap and an outer periphery of the end portion. A fusible element may be disposed within the hollow body, the fusible element may be further disposed within the cavity formed between the inside surface of the endcap and the outer periphery of the end portion, the fusible element traveling a substantially diagonal path through a center of the cavity.

A sealed fuse in accordance with the present disclosure may include a tubular fuse body, a trench formed in an exterior of the fuse body, and an electrically conductive endcap that fits over an end of the fuse body and is fastened to the fuse body by an electrically conductive material having a lip portion that extends into the trench to provide a barrier that extends between the fuse body and the endcap. In an embodiment, the trench may be formed in an end face of the fuse body and may extend entirely around an opening in the end of the fuse body. In another embodiment, the trench may be formed in an outwardly-facing surface of a sidewall of the fuse body and may extend entirely around the fuse body.

A fuse includes a fuse body, two terminals, and a termination reinforcement. The fuse body surrounds a fusible element. The first terminal is located at one end of the fuse body and the second terminal is located at the other end of the fuse body. The fusible element is mechanically connected to the first and second terminals. The termination reinforcement is located at one end of the fuse body.

The present disclosure describes an electric fuse, comprising a melting member contained within an insulated cylindrical casing, which is sealed at each end by an electrically conductive cover electrically connected to said melting member. On each end of the fuse casing, between said casing and said cover, is installed an electrically conductive and plastically deformable separating barrier. On the side of separating barrier facing the interior of the casing is affixed a layer of an elastic and electrically insulating material. The melting member is on each end portion of said fuse electrically connected with each cover via said separating barrier and proceeds through said electrically insulating layer. Within said layer the melting member has at least one bend, by which it is anchored therein and secured against being pulled out.

Embodiments of the fuse include a fuse body having a first end and a second end. A fuse element is disposed within a cavity of the fuse body, an end of the fuse element extending beyond an edge of the fuse body. An arc disc is disposed on the edge of the fuse body, and includes a notch such that the end of the fuse element extends to an outer surface of the arc disc. The end of the fuse element is configured to be folded over the outer surface of the arc disc. An end cap is disposed over the end of the fuse body and the arc disc, and the end cap includes a hole at a top surface. Solder deposited within the hole provides an electrical connection between the arc disc, the fuse element, and the end cap.
