Abstract
A fuse assembly includes a fuse element, a first terminal, a second terminal, a socket, and a capsule. The fuse element is disposed between first and second end bells. The first terminal includes a first bell portion, a first socket portion, and a first capsule portion, the first bell portion being connected to the first end bell. The second terminal includes a second bell portion, a second socket portion, and a second capsule portion, the second bell portion being connected to the second end bell. The first socket portion and the second socket portion are integrated through the socket. The first capsule portion and the second capsule portion are integrated through the capsule. The socket is seated atop the capsule to create an interior chamber inside which the fuse element is disposed.
Claims15
A fuse assembly comprising:
- a fuse element coupled between a first end bell and a second end bell;
- a first terminal comprising a first bell portion, a first socket portion, and
- a first capsule portion, wherein the first bell portion is coupled to the first end bell;
- a second terminal comprising a second bell portion, a second socket portion, and a second capsule portion, wherein the second bell portion is coupled to the second end bell;
- a socket through which the first socket portion and the second socket portion are integrated, the socket comprising an exhaust port disposed between an inside surface of the socket and an outside surface of the socket and providing a plurality of pathways therebetween, the exhaust port providing a pathway for outgassing of debris in response to the fuse element breaking, the exhaust port comprising:
- an entrance at the inside surface of the socket;
- an exit at the outside surface of the socket;
- and
- a plurality of chambers disposed between the entrance and the exit, the plurality of chambers being perpendicular to the plurality of pathways;
- and
- a capsule through which the first capsule portion and the second capsule portion are integrated;
- wherein the socket is seated atop the capsule to create an interior chamber inside which the fuse element is disposed.
A fuse assembly comprising:
- a capsule comprising a first inside surface disposed between a first capsule terminal region and a second capsule terminal region, the first inside surface comprising capsule wedges;
- a socket comprising a second inside surface, the second inside surface comprising socket wedges, wherein the socket is disposed on the capsule to form an interior chamber, the capsule wedges being on a first side of the interior chamber and the socket wedges being on a second side of the interior chamber, wherein the first side is opposite the second side, the socket further comprising an exhaust port comprising a plurality of pathways from the interior chamber to an outside surface of the socket, the exhaust port providing a pathway for outgassing of debris in response to the fuse element breaking, the exhaust port further comprising:
- an entrance leading from the interior chamber;
- an exit at the outside surface;
- and
- a plurality of chambers disposed between the entrance and the exit, the plurality of chambers being perpendicular to the plurality of pathways;
- and
- first and second terminals connecting between a fuse element, the fuse element being in the interior chamber, each terminal comprising a first portion integrated with the capsule and a second portion integrated with the socket.
