A pressure-compensated fuse assembly may include a first chamber housing a first fluid and a plurality of solid particles. Additionally, the fuse assembly may include a second chamber housing a second fluid. Further, the fuse assembly may include a pressure compensator disposed between the first chamber and the second chamber. The pressure compensator may be configured to transfer pressure from the second fluid in the second chamber to the plurality of solid particles in the first chamber.

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.

A dual element electrical fuse includes at least one high overcurrent fusible element and a low overcurrent fusible element connected to one another inside a housing. The low overcurrent fusible element includes a single sided circuit board and a releasable conductive element that more simply provides low overcurrent protection and manufacturing efficiency with improved quality.

A fuse unit includes a fuse element which includes a fusible portion, a housing which accommodates the fuse element in a state that the fusible portion is exposed to an outside thereof, and a cover which is attached to the housing so as to cover the fusible portion. The cover includes a pair of side wall portions which is disposed so as to face each other with the fusible portion interposed therebetween, and a connection portion which connects the pair of side wall portions. The housing includes a guide wall which is configured to guide the cover toward the fusible portion when the cover is attached to the housing. The guide wall is inclined to a direction intersecting a separation direction in which the cover is separated from the housing.

The present disclosure includes an insert for a fuse structure. In one approach, a fuse, includes a housing having a cavity, a fuse element disposed within the cavity, a plurality of terminals extending out of the housing and electrically connected to the fuse element, and an insert disposed in the cavity, the insert including a pin extending through an opening of the housing. In some approaches, the insert includes a separating wall defining first and second cavities of the insert.

Therefore, the invention of the present application provides a fuse in which a position and a posture of a fuse element are easily stabilized and which is easily assembled, and a method for manufacturing the fuse. A fuse including a fuse element having a fusing portion; and a casing accommodating the fusing portion; where the fuse element has a long shape extending in a longitudinal direction of the casing and at least two or more fuse elements are provided; the fuse element has one end portion side coupled to each other by a coupling portion; a first holding portion that holds the fuse element is provided in one opening of the casing; and a locking portion that locks the coupling portion of the fuse element is provided in the first holding portion.
