A safety fuse for use in a motor vehicle includes which fuse comprises a first contact metal portion, a second contact metal portion and a melting metal section connecting the first contact portion to the second contact portion. The melting section is enclosed by a casing made from a non-conductive material and includes two hollow half-shells provided with mutual coupling elements, each half-shell having an inner surface facing the melting section and an outer surface facing outside of the fuse. At least one of the half-shells is provided on at least part of the inner surface of an alveolar structure with open cells in the direction of the melting section. The alveolar structure is formed by a plurality of walls protruding from the inner surface and intersected with each other.

Provided is a fuse device used for high rating and high current applications excellent in impact resistance at the time of current interruption, and capable of preventing falling off of the case. The fuse device includes: a base member; a cover member fitted to the base member and covering a surface of the base member; and a fuse element mounted on the surface of the base member; wherein one of the base member and the cover member is provided with a side wall intersecting with the plane of the surface of the base member and including an opening formed therein, and the other of the base member and the cover member is provided with a fitting projection projecting outward from a plane intersecting with the plane of the surface of the base member and fitted into the opening of the side wall.

A current-limiting fuse for an electronic apparatus, such as, for example, a transformer. The fuse can be withdrawable under a liquid insulating medium, such as oil, and is capable of being replaceable in the field. The fuse can include a fuse element that is encased within an electrically insulative sheath. Additionally, a plurality of contact blades can extend from a lower portion of the fuse and be securely engaged with contact clips that are in electrical communication with one or more components of the electronic apparatus. The contact blades can be positioned within a dielectric insulating medium while a reminder of the fuse between the contact blades and the enclosure can be positioned within an air gap. Further, the contact blades can accommodate seating of the fuse within the enclosure and/or an associated canister.

Exemplary embodiments of the present disclosure of a fuse may include a fuse body having a first portion and a second portion. The first and second portions may be configured to mate together thereby forming an internal cavity. A first inner termination and a second inner termination may be at least partially attachable to the first and second portions of the fuse body at respective first and second ends. A fusible element may be disposed in the cavity of the fuse body and extendable from the first inner termination at the first end of the fuse body to the second inner termination at the second end of the fuse body. The fusible element may be attachable to the first inner termination at a first connection and the second inner termination at a second connection. The first and second connections may be inspectable when the fuse is in an assembled state.

A fuse including a fuse body, a fusible element disposed within the fuse body providing an electrically conductive pathway extending between a first end of the fuse body and a second end of the fuse body, and a heat shield disposed within the fuse body intermediate an interior surface of the fuse body and an exterior surface of the fuse body for mitigating heat flow therebetween.

A sub-structure element support system is disclosed. The sub-structure element support system includes a novel molded structure designed to support an electrical element, such as a fuse. The molded structure is a protective and insulative sleeve for the electrical element and reduces forces on the electrical element during free-fall and operation conditions. The molded structure also facilitates automation during manufacturing and reduces cost.

A power distribution box assembly can include a power distribution box housing, a fuse block, and a plurality of eyelet terminals. The fuse block can include a stamped busbar assembly, a plurality of studs, and a housing. The stamped busbar assembly can include a main power supply portion, a plurality of fuse elements, and a plurality of terminal connecting portions coupled to the plurality of fuse elements. Each of the plurality of terminal connecting portions can: (i) extend from its respective fuse element in a terminal direction that is orthogonal to both directions that the main power supply portion and the fuse elements extend.

Provided is a battery that may include a first terminal or cable, a second terminal or a cable, a thermal fuse configured to connect to the first terminal or cable and the second terminal or cable, a first sleeving layer that is disposed on the thermal fuse, and that is configured to muffle an arc explosion of the thermal fuse and encapsulate molten material generated by the arc explosion of the thermal fuse, and a second sleeving layer that is disposed on the first sleeving layer, and that is configured to encapsulate the molten material generated by the arc explosion of the thermal fuse that penetrates the first sleeving layer. An overcurrent protection system and a sleeving are also provided.
