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.
Claims19
A fuse comprising:
- a housing having an upper portion and a lower portion;
- a plurality of terminal portions disposed in the lower portion of the housing, 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;
- a fusible link disposed in the upper portion of the housing and 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;
- and
- a partition extending from said upper portion of said housing into said lower portion of said housing, wherein a distance between each of the second prongs and the partition increases from a first end of each of the second prongs proximate the upper portion to a second end of each of the second prongs distal from the upper portion for allowing the second ends to be displaced a distance toward the partition before engaging the partition.
2 more elements
A fuse comprising:
- a housing having a first and second halves and defining an upper portion and a lower portion;
- 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;
- a partition extending from said upper portion of said housing into said lower portion of said housing, wherein a distance between each of the second prongs and the partition increases from a first end of each of the second prongs proximate the upper portion to a second end of each of the second prongs distal from the upper portion for allowing the second ends to be displaced a distance toward the partition before engaging the partition.
2 more elements
A fuse comprising:
- housing having first and second outside walls and defining an upper portion and a lower portion;
- 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;
- and
- a partition extending from said upper portion of said housing into said lower portion of said housing, wherein a distance between each of the second prongs and the partition increases from a first end of each of the second prongs proximate the upper portion to a second end of each of the second prongs distal from the upper portion for allowing the second ends to be displaced a distance toward the partition before engaging the partition.
