Abstract

Abstract This specification discloses a fuse holder for an automotive terminal block for receiving fuses and electrical connections to various electrical components of the automobile. The fuse holder is positioned within the terminal block and is adapted to receive the blade contact of a fuse thereby establishing an electrical connection to the fuse. Typically, the fuse holder has a spring clip with two prongs spring biased against one another so that the blade contact can be resiliently secured between two prongs. The fuse holder can have a pair of attaching prongs to hold a wire providing an electrical connection to the fuse holder. A stop tab is positioned adjacent the attaching prongs so that a wire slipped between the attaching prongs is limited in movement toward the spring clip of the fuse holder so that it does not interfere with entry of the fuse blade between the two prongs.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 299 words
A fuse holder for use in a terminal block for providing connection between an automobile electrical system and fuses used in connection with the automotive electrical system, said fuses being of a miniature nature and having a pair of blade contacts, said fuse holder having a spring clip with a pair of prongs adapted for holding therebetween a blade contact of said fuse and a pair of attachment means for attaching an electrically conductive wire to said fuse holder; said fuse holder further including a stop means longitudinally aligned with the wire to be connected and positioned between the wire and said two prongs of said fuse holder so that portions of said wire do not interfere with said prongs and impede connection to said blade contact of the fuse; said fuse holder includes a plurality of spring clips, each having a laterally extending bus bar portion which together form an elongated bus bar from which said spring clips extend at spaced intervals; said elongated bus bar having a first elongated path and a second elongated path, said first and second paths being generally parallel with spacing therebetween, said first and second elongated paths being connected by spaced reinforcing members extending between said first and second paths; and at least some of said spaced reinforcing members having extending therefrom a pair of attaching prongs for receiving the electrically conducting wire of a lead to be connected to said fuse holder so that when an electrical wire is attached to said fuse holder by said attaching prongs, electrical access to said electrical lead is available both through said first path and said second path, thereby, for a given fuse holder width, increasing the current carrying capacity of said fuse holder in comparison to a fuse holder having a single path.
Claim 2
Dependent Claim 299 words
A fuse holder for use in a terminal block for providing connection between an automobile electrical system and fuses used in connection with the automotive electrical system, said fuses being of a miniature nature and having a pair of blade contacts, said fuse holder having a spring clip with a pair of prongs adapted for holding therebetween a blade contact of said fuse and a pair of attachment means for attaching an electrically conductive wire to said fuse holder; said fuse holder further including a stop means longitudinally aligned with the wire to be connected and positioned between the wire and said two prongs of said fuse holder so that portions of said wire do not interfere with said prongs and impede connection to said blade contact of the fuse; said fuse holder includes a plurality of spring clips, each having a laterally extending bus bar portion which together form an elongated bus bar from which said spring clips extend at spaced intervals; said elongated bus bar having a first elongated path and a second elongated path, said first and second paths being generally parallel with spacing therebetween, said first and second elongated paths being connected by spaced reinforcing members extending between said first and second paths; and at least some of said spaced reinforcing members having extending therefrom a pair of attaching prongs for receiving the electrically conducting wire of a lead to be connected to said fuse holder so that when an electrical wire is attached to said fuse holder by said attaching prongs, electrical access to said electrical lead is available both through said first path and said second path, thereby, for a given fuse holder width, increasing the current carrying capacity of said fuse holder in comparison to a fuse holder having a single path.
Claim 3
Dependent Claim 67 words
A fuse holder as recited in claim 1 further comprising a pair of securing prongs which are positioned on the other side of said second conducting path from said attaching prongs, said securing prongs being aligned with said attaching prongs so that said securing prongs can grasp the insulating material surrounding the wire lead, thereby improving the physical connection between said fuse holder and said wire lead.
Claim 4
Dependent Claim 21 words
A fuse holder as recited in claim 2 wherein said securing prongs, said attaching prongs and said spring clips are aligned.
Claim 5
Dependent Claim 35 words
A fuse holder as recited in claim 3 wherein said stop means is longitudinally aligned with said attaching prongs so that said stop means prevents inadvertent insertion of said wire lead into said spring clip.
Claim 6
Dependent Claim 16 words
A fuse holder as recited in claim 4 wherein only alternate reinforcing members include attaching prongs.
