Abstract
A fuse may include a housing having a cavity. The fuse may also include a fuse element disposed within the cavity; a plurality of terminals extending out of the housing and electrically connected to the fuse element; and porous material disposed in the cavity adjacent to the fuse element, the porous material having a plurality of pores, the porous material further comprising an open pore structure wherein at least some of the pores are disposed on an outer surface of the porous material facing the fuse element.
Claims17
A fuse, comprising:
- 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
- porous material disposed in the cavity, the porous material having a plurality of pores, the porous material further comprising an open pore structure wherein at least some of the pores are disposed on an outer surface of the porous material facing the fuse element;
- wherein the housing comprises a plurality of ribs engaging the porous material, wherein the porous material is in a compressed state when the fuse is assembled.
3 more elements
A method of forming a fuse, comprising:
- providing a fuse structure comprising a fuse element and a first terminal and a second terminal connected to the fuse element;
- providing a first housing part and a second housing part;
- providing a porous material between the fuse element and at least one of the first housing part and the second housing part;
- and
- assembling the first housing part to the second housing part, wherein the first housing part and the second housing part define a cavity retaining the porous material, the porous material having a plurality of pores, the porous material further comprising an open pore structure wherein at least some of the pores are disposed on an outer surface of the porous material facing the fuse element;
- wherein at least one of the first housing part and the second housing part comprises a plurality of ribs, wherein the assembling comprises compressing the porous material against the plurality of ribs.
3 more elements
A fuse, comprising:
- a fuse element;
- a first terminal connected to a first portion of the fuse element;
- a second terminal connected to a second portion of the fuse element;
- a housing defining a first cavity region disposed on a first side of the fuse element and a second cavity region disposed on a second side of the fuse element opposite the first side;
- a first porous piece disposed in the first cavity region;
- and
- a second porous piece disposed in the second cavity region, the first porous piece and the second porous piece comprising a plurality of pores having an open pore structure wherein at least some pores are disposed on a first outer surface of the first porous piece and the second outer surface of the second porous piece, the first outer surface and the second outer surface facing the fuse element;
- wherein the housing comprises a plurality of ribs engaging the first porous piece in the first cavity region and the second porous piece in the second cavity region, wherein the first porous piece and the second porous piece are in a compressed state when the fuse is assembled.
