Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
86 words
A wire-connector for making solderless connection to wires of a compact flat cable, comprising a contact element having a flat metal plate body having parallel closely spaced sharp-ended prongs extending from one edge, including two outer prongs lying in a common plane and an inner prong lying in a plane parallel to said plane and offset therefrom by no more than twice the thickness of said plate, the ends of said prongs sloping inwardly toward the space between said planes to define a terminal wire-receiving trough.
Claim 2
Dependent Claim
86 words
A wire-connector for making solderless connection to wires of a compact flat cable, comprising a contact element having a flat metal plate body having parallel closely spaced sharp-ended prongs extending from one edge, including two outer prongs lying in a common plane and an inner prong lying in a plane parallel to said plane and offset therefrom by no more than twice the thickness of said plate, the ends of said prongs sloping inwardly toward the space between said planes to define a terminal wire-receiving trough.
Claim 3
Dependent Claim
54 words
Wire-connector of claim 1 including an insulating base for supporting a said cable and containing at least one said contact element in position for making contact with a corresponding wire, and an insulating cover for retaining said cable in position against said base and having pockets for receiving the extended prongs of said elements.
Claim 4
Dependent Claim
29 words
Wire-connector of claim 2 wherein said elements include an extension opposite the extended prongs and passing through at least a portion of said base for providing an external contact.
