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.

A power fuse assembly includes a fuse mounting, a fuse unit, and a hinge assembly. The fuse unit is configured to carry current from a line connection to a load connection. The hinge assembly is configured to be removeably coupled to the fuse unit and to allow rotation of the fuse unit relative to the fuse mounting. The hinge assembly including: an inlet configured to accept incoming gases produced by the fuse unit in response to an overload event, the inlet having a first orientation; an outlet in fluid communication with the inlet, the outlet having a second orientation that is not equal to the first orientation; and a diverter component disposed between the inlet and the outlet, the diverter configured to guide the flow of the gases between the inlet and the outlet.

A fuse housing for safe outgassing of a fuse is disclosed. The fuse housing features labyrinth walls disposed at opposing sides of the fuse housing. The labyrinth walls feature serpentine paths for the flow of outgassing material. At an end of the serpentine paths which is farthest away from a fuse element are vent channels. The vent channels are narrower in depth than that of the serpentine paths of the labyrinth walls, facilitating a suctioning effect during outgassing. Conductive material deposits along the serpentine paths so that the fuse maintains a high OSR rating. By directing and controlling the outflow of gases, the fuse housing is able to reduce the temperature of the gases produced. The fuse housing is also able to reduce the physical and observable effects of outgassing.

Provided is a protecting device that can prevent damage of the device by releasing the pressure inside the housing by providing openings in the housing and can secure appropriate insulation. The protecting device includes: a meltable conductor 3; first and second external connection terminals 7, 8 connected to both ends of the meltable conductor 3; and a housing 6 having a lower case 4 and an upper case 5, wherein one end of the first external connection terminal 7 and one end of the second external connection terminal 8 are led out from the housing 6, and the housing is provided with a first opening 24 formed facing a front surface of the first external connection terminal 7 and a second opening 25 formed facing a front surface of the second external connection terminal 8.

A fuse module including a mounting block having a through-hole extending therethrough, a fuse including an upper portion disposed on a top of the mounting block and having a through-hole, a lower portion disposed on a bottom of the mounting block and having a through-hole, and a fusible element disposed adjacent a sidewall of the mounting block and connecting the upper portion to the lower portion, the fuse module further including a housing having a main body portion encasing the mounting block and the fuse, the main body portion having apertures in top and bottom surfaces thereof aligned with the through-hole of the mounting block, and a cap portion connected to the main body portion and disposed over the fusible element, the cap portion having surface features extending from an interior surface thereof for absorbing energy upon occurrence of an overcurrent condition in the fuse.

The invention relates to a conducting track fuse (1) for an electrical or electronic device, comprising: a first and a second connection region (2a, 2b); a nonlinearly extending burn-out region (3), which is arranged between the first and second connection regions (2a, 2b); and a covering element (15), which has at least two side walls (9) and a covering face (8), which covering element is arranged over the first and second connection regions (2a, 2b) and over the burn-out region (3), the burn-out region (3) and the covering element (5) being arranged relative to each other in such a way that the area of the covering face (8) covers the burn-out region (3) and a cavity (7) is formed between the burn-out region (3) and the covering face (8) as a result of the height of the side walls (9).

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.
