Abstract
A fuse employing a plurality of tuning fork terminal configurations with an improved current capacity within a smaller footprint and a housing design to provide the terminals with insert protection and strain relief.
Claims20
A fuse comprising:
- a plurality of terminal portions, each of said terminal portions having first and second prongs and a gap disposed therebetween, wherein the gap narrows from a first width adjacent an upper end of said first and second prongs to a second width adjacent a lower end of said first and second prongs, said gap configured to receive terminals therein;
- and
- a fusible link disposed between said plurality of terminal portions, said fusible link configured to interrupt current flowing between said plurality of terminal portions upon certain high current conditions;
- wherein each of the plurality of terminal portions has a first thickness T1 measured in a direction perpendicular to the first and second widths and the fusible link has a second thickness T2 measured in a direction perpendicular to the first and second widths, where T1 is greater than T2.

A fuse comprising:
- a housing having a first and second halves;
- a strain relief assembly centrally disposed within at least said first half;
- and
- a fusible member having first and second terminal portions and a fusible link connected between said first and second terminal portions, each of said first and second terminal portions having first and second prongs with a gap disposed therebetween, wherein the gap narrows from a first width adjacent an upper end of said first and second prongs to a second width adjacent a lower end of said first and second prongs, said fusible member disposed within said housing when said first and second halves are coupled together such that an upper portion of each of said first and second first and second terminal portions engages said strain relief assembly when a receiving terminal is inserted into said gap;
- wherein each of the plurality of terminal portions has a first thickness T1 measured in a direction perpendicular to the first and second widths and the fusible link has a second thickness T2 measured in a direction perpendicular to the first and second widths, where T1 is greater than T2.

A fuse comprising:
- housing having a first and second outside walls;
- and
- a fusible member having first and second terminal portions and a fusible link connected between said first and second terminal portions, each of said first and second terminal portions having first and second prongs and a gap disposed therebetween, wherein the gap narrows from a first width adjacent an upper end of said first and second prongs to a second width adjacent a lower end of said first and second prongs, said gap configured to receive terminals therein, said fusible member disposed within said housing such that said first prong of each of said terminals engages a respective one of said outside walls when a receiving terminal is inserted into said gap;
- wherein each of the plurality of terminal portions has a first thickness T1 measured in a direction perpendicular to the first and second widths and the fusible link has a second thickness T2 measured in a direction perpendicular to the first and second widths, where T1 is greater than T2.
