Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
176 words
A one-piece electrical contact formed from a blank of sheet material, said blank comprising: first and second contact elements for folding in overlapping relationship with one another about a first axis between said first and second contact elements; said first contact element including first and second contact fingers symmetrically disposed with respect to a second axis extending between said first and second contact fingers for folding into a plane substantially normal to the plane of said sheet material; said second contact element including third and fourth contact fingers symmetrically disposed with respect to a third axis extending between said third and fourth fingers for folding into a plane substantially normal to the plane of said sheet material, a tongue extending between said third and fourth contact fingers for holding said first and second contact elements in closely abutting overlapping relationship; said first and third contact fingers and said second and fourth contact fingers are respectively symmetrically positioned with respect to said first axis; and a flange element for forming a connector to receive an electrical conductor.
Claim 2
Dependent Claim
176 words
A one-piece electrical contact formed from a blank of sheet material, said blank comprising: first and second contact elements for folding in overlapping relationship with one another about a first axis between said first and second contact elements; said first contact element including first and second contact fingers symmetrically disposed with respect to a second axis extending between said first and second contact fingers for folding into a plane substantially normal to the plane of said sheet material; said second contact element including third and fourth contact fingers symmetrically disposed with respect to a third axis extending between said third and fourth fingers for folding into a plane substantially normal to the plane of said sheet material, a tongue extending between said third and fourth contact fingers for holding said first and second contact elements in closely abutting overlapping relationship; said first and third contact fingers and said second and fourth contact fingers are respectively symmetrically positioned with respect to said first axis; and a flange element for forming a connector to receive an electrical conductor.
Claim 3
Dependent Claim
14 words
The structure as in claim 1 wherein said second and third axes are co-linear.
Claim 4
Dependent Claim
20 words
The structure as in claim 1 wherein said second and third axes are in spaced parallel relationship to one another.
Claim 5
Dependent Claim
50 words
The structure as in claim 2 wherein said first contact element further includes first and second projections symmetrically formed with respect to said second axis and the respective free ends thereof are spaced a distance less than the width of said tongue to form an aperture for retaining said tongue.
Claim 6
Dependent Claim
50 words
The structure as in claim 3 wherein said first contact element further includes first and second projections symmetrically formed with respect to said second axis and the respective free ends thereof are spaced a distance less than the width of said tongue to form an aperture for retaining said tongue.
Claim 7
Dependent Claim
186 words
A one-piece electrical contact of the fork-shaped contact type, comprising: first and second contact elements folded in overlapping relationship with one another about a first axis between said first and second contact elements; said first contact element including first and second planar contact fingers symmetrically disposed with respect to a second axis extending between said first and second contact fingers, the respective surfaces of said first and second contact fingers extend substantially normal to the plane of said first and second contact elements; said second contact element including planar third and fourth contact fingers symmetrically disposed with respect to said second axis, the surfaces of said third and fourth contact fingers extend substantially substantially normal to the plane of said first and second contact elements, whereby said first and second and said third and fourth contact fingers are respectively aligned to form opposing arms of said fork-shaped contact, a tongue extending between said opposing arms and overlapping said first contact element for holding said first and second contact elements in said overlapping relationship; and a flange element formEd into a connector to receive an electrical conductor.
Claim 8
Dependent Claim
186 words
A one-piece electrical contact of the fork-shaped contact type, comprising: first and second contact elements folded in overlapping relationship with one another about a first axis between said first and second contact elements; said first contact element including first and second planar contact fingers symmetrically disposed with respect to a second axis extending between said first and second contact fingers, the respective surfaces of said first and second contact fingers extend substantially normal to the plane of said first and second contact elements; said second contact element including planar third and fourth contact fingers symmetrically disposed with respect to said second axis, the surfaces of said third and fourth contact fingers extend substantially substantially normal to the plane of said first and second contact elements, whereby said first and second and said third and fourth contact fingers are respectively aligned to form opposing arms of said fork-shaped contact, a tongue extending between said opposing arms and overlapping said first contact element for holding said first and second contact elements in said overlapping relationship; and a flange element formEd into a connector to receive an electrical conductor.
Claim 9
Dependent Claim
51 words
An electrical contact as in claim 6 wherein said first connector element further includes first and second projections symmetrically formed with respect to said second axis and the respective free ends thereof are spaced a distance less than the width of said tongue to form an aperture for retaining said tongue.
Claim 10
Dependent Claim
19 words
An electrical contact as in claim 7 wherein said respective free ends are folded into engagement with said tongue.
