Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
174 words
Apparatus comprising: a substantially planar electrical insulator; first and second electrically conductive conductors extending from one side of said insulator, said conductors being spaced and electrically insulated from each other and each of said conductors being adapted to mechanically and electrically engage a fuse clip; first and second electrically conductive fuse clips extending from the other side of said insulator, said fuse clips being electrically connected to each other and to said first conductor; a third electrically conductive fuse clip extending from said other side of said insulator, said third fuse clip being electrically connected to said second conductor, said third fuse clip extending from said insulator relative to said first fuse clip in position to be electrically connected thereto by a fuse; and, a fourth electrically conductive fuse clip extending from said other side of said insulator relative to said second fuse clip in position to be electrically connected thereto by a fuse, said fourth fuse clip being electrically insulated from said first, second and third fuse clips and from said second connector.
Claim 2
Dependent Claim
174 words
Apparatus comprising: a substantially planar electrical insulator; first and second electrically conductive conductors extending from one side of said insulator, said conductors being spaced and electrically insulated from each other and each of said conductors being adapted to mechanically and electrically engage a fuse clip; first and second electrically conductive fuse clips extending from the other side of said insulator, said fuse clips being electrically connected to each other and to said first conductor; a third electrically conductive fuse clip extending from said other side of said insulator, said third fuse clip being electrically connected to said second conductor, said third fuse clip extending from said insulator relative to said first fuse clip in position to be electrically connected thereto by a fuse; and, a fourth electrically conductive fuse clip extending from said other side of said insulator relative to said second fuse clip in position to be electrically connected thereto by a fuse, said fourth fuse clip being electrically insulated from said first, second and third fuse clips and from said second connector.
Claim 3
Dependent Claim
11 words
The apparaTus of claim 1 wherein said conductors are fuse clips.
Claim 4
Dependent Claim
88 words
The apparatus of claim 1 wherein said insulator is a synthetic resin; and, wherein said first and second fuse clips are mechanically and electrically secured to a flat strip of electrically conductive material having an aperture intermediate said first and second fuse clips, said first conductor having a portion extending through an aperture in said insulator and through the aperture in said flat strip, the extremity of said portion overlying said flat strip to mechanically and electrically secure said first conductor to said first and second fuse clips.
Claim 5
Dependent Claim
109 words
The apparatus of claim 1 wherein at least one of said first and second fuse clips and at least one of said third and fourth fuse clips are respectively secured to first and second flat strips of electrically conductive material; and, wherein said first and second conductors include a portion extending respectively through an aperture in said insulator and in one of said flat strips and overlying the respective one of said flat strips to thereby establish an electrical and mechanical connection between said first conductor and one of said first and second fuse clips and between said second conductor and one of said third and fourth fuse clips.
Claim 6
Dependent Claim
26 words
The apparatus of claim 1 wherein said conductors have a generally cylindrical cross-section at the end thereof to mechanically and electrically engage a female fuse clip.
Claim 7
Dependent Claim
88 words
The apparatus of claim 3 wherein said insulator is a synthetic resin; and, wherein said first and second fuse clips are mechanically and electrically secured to a flat strip of electrically conductive material having an aperture intermediate said first and second fuse clips, said first conductor having a portion extending through an aperture in said insulator and through the aperture in said flat strip, the extremity of said portion overlying said flat strips to mechanically and electrically secure said first conductor to said first and second fuse clips.
