Disclosed are various protection devices and associated methods. In some embodiments, a protection device may include a fuse assembly having a fusible link extending between a first lead end and a second lead end, and a first lead extending from the first lead end and a second lead extending from the second lead end. The protection device may further include a body including a first section coupleable with a second section, wherein the first and second sections define a central cavity housing the fusible link. The first section may include an interior face operable to engage an opposite interior face of the second section, an engagement member extending away from the interior face towards the second section, and an engagement channel adjacent the engagement member, the engagement channel operable to receive a corresponding engagement member of the second section.

An easy-to-assemble fuse has a fusible body, a socket, and a cover. The fusible body is engaged with the socket. The cover is covered on the socket and the fusible body and is engaged with the socket. By the engagement between the fusible body and the socket and the engagement between the socket and the cover, the fuse achieves the purpose of fast alignment and positioning. The fuse can be quickly assembled during the manufacturing process, thereby simplifying the manufacturing process, and reducing the production cost.

A fuse assembly includes a fuse element and a terminal vent channel. The fuse element is located between a first terminal and a second terminal. The fuse element breaks in response to an overcurrent event. The terminal vent channel is located in the first terminal and provides a path for the outgassing of debris during the overcurrent event.

The present utility model relates to a fuse, a vehicle circuit for an electric vehicle, and an electric vehicle. The fuse has a longitudinal direction and a transverse direction, and includes: a bushing, having a through-hole cavity extending in the longitudinal direction and for accommodating quartz sand and two end surfaces in the longitudinal direction; a fuse body, accommodated in the through-hole cavity; and two contact blades, positioned at two ends of the through-hole cavity and conductively joined to the fuse body. At least one of the contact blades comprises a first section coming into direct sealing contact with one of the end surfaces of the bushing by covering the through-hole cavity, and an overhanging arm section extending from the first section. The overhanging arm section includes a second section extending, in a direction perpendicular to the longitudinal direction, out of the bushing.

A fuse assembly including a fuse connected to two busbars, an injection molded base and an injection molded cover. The busbars are powder-coating with a powder-based adhesive or adhesion promoter, then cured in an oven. The busbars are then placed in the cavity image of an injection molding apparatus. Plastic is heated to a liquid form and injected into the cavity image. The resulting injection molded base is resistant to both dust and water, protecting the fuse inside.
