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.

High breaking capacity fuses with metal reinforcements

Provided are circuit protection devices. In some embodiments, a protection device may include a set of leads extending though a socket body, wherein the socket body includes a first side opposite a second side, and a third side opposite a fourth side, wherein the third and fourth sides extend between the first and second sides, and wherein the third side includes a thermal vent. The protection device may further include a fusible element surrounding a central shaft, wherein the fusible element is connected with the set of leads.

Protection device with wall vent for breaking capacity improvement

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.

Protection device including radial lead fuse

A surface mount fuse including a fuse body having a base including a floor and a plurality of adjoining sidewalls defining an interior cavity, wherein top edges of the sidewalls define a recessed shoulder bordering the interior cavity, and a cover including a main body disposed on the recessed shoulder and enclosing the interior cavity, first and second terminals extending through opposing sidewalls of the base, the first and second terminals extending around the opposing sidewalls and the cover and disposed in abutment therewith to secure the cover to the base, and a fusible element extending through the interior cavity and connected to the first and second terminals.

Surface mount fuse

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.

Hollow fuse body with notched ends

Provided herein are protection devices, such as fuses, including a set of trenches or pockets for retention of solder therein. In some embodiments, a fuse includes a body including a center portion extending between a first and second end portions. The first end portion includes a first trench formed in a first end surface, and the second end portion includes a second trench formed in a second end surface. The fuse may further include a first and second endcaps surrounding respective first and second end portions. The fuse may include a fusible element disposed within a central cavity of the body, the fusible element extending between the first end surface and the second end surface. In some embodiments, solder may be disposed within the first trench and the second trench, wherein the solder is in contact with the fusible element, the first endcap, or the second endcap.

Hollow fuse body with trench

Provided herein are improved electrical circuit protection devices for protection against electrostatic discharge (ESD), the devices including a first support substrate, a first electrode and a second electrode formed on the first support substrate, wherein the first electrode and the second electrode are formed from a conductive material. The devices further include a first bonding pad disposed on the first and second electrode, the first bonding pad having a first cavity formed therein; a second support substrate disposed on the first bonding pad, the second support substrate having a second cavity formed therein, and a voltage variable material disposed within the first cavity and the second cavity and electrically connected to the first electrode and the second electrode. The devices further include a second bonding pad disposed on the second support substrate, and a third support substrate disposed on the second bonding pad.

Surface-mountable electrical circuit protection device

An improved fuse including a fuse body formed of an electrically insulative material. The fuse body defines a cavity which extends from a first end of the fuse body to a second end of the fuse body. A fusible element is disposed within the cavity and extends from a first end face of the first end of the fuse body to a second end face of the second end of the fuse body. Insulated plugs are disposed within the cavity at the first and second ends of the fuse body wherein the plugs adhere to an interior surface of the fuse body and form seals that close the internal cavity. The fuse may further include end terminations that are applied to the ends of the fuse body in electrical contact with the fusible element.

Fuse with insulated plugs

A surface mount fuse in one embodiment includes an insulative body, first and second conductive and caps attached to the insulative body, each end cap defining an aperture, and a fuse element extending (i) through the insulative body and the apertures and (ii) along outside surfaces of the first and second conductive end caps in such a way that solder used to attach the first and second conductive end caps to an external medium also fastens the fuse element to the first and second end caps.
