Abstract
Provided herein are protection devices, such as fuses, including a coiled fusible element. In some embodiments, a fuse includes a body including a center portion extending between a first end and a second end, and a first endcap surrounding the first end and a second endcap surrounding the second end. The fuse may further include a fusible element disposed within a central cavity of the body, wherein the fusible element includes a first coil disposed within the first endcap and a second coil disposed within the second endcap. The fusible element further includes a central wire extending diagonally between the first and second coils.
Claims18
A fuse comprising:
- a body including a center portion extending between a first end and a second end;
- a first endcap surrounding the first end and a second endcap surrounding the second end;
- and
- a fusible element disposed within a central cavity of the body, the fusible element comprising:
- a first coil disposed within the first endcap and a second coil disposed within the second endcap;
- and
- a straight central wire extending diagonally between the first and second coils.
A protection device comprising:
- a body;
- a first endcap surrounding a first end of the body, and a second endcap surrounding a second end of the body;
- and
- a fusible element extending between the first end of the body and the second end of the body, wherein the fusible element is disposed within a central cavity of the body, and wherein the fusible element comprises:
- a first coil disposed within the first endcap and a second coil disposed within the second endcap;
- and
- a straight central wire extending diagonally between the first and second coils.
A fusible device comprising:
- a hollow body;
- a first endcap surrounding a first end of the hollow body, and a second endcap surrounding a second end of the hollow body;
- and
- a fusible element extending between the first end of the hollow body and the second end of the body, wherein the fusible element is disposed within a central cavity of the hollow body, and wherein the fusible element comprises:
- a first coil partially disposed within the first endcap, the first coil having a plurality of loops wound about a central axis;
- a second coil having a plurality of loops wound about the central axis;
- and
- a straight central wire having a first end integrally coupled to the first coil and a second end integrally coupled to the second coil, the straight central wire extending diagonally through the central cavity with respect to the central axis.
