Abstract
Abstract Connections to one or more wires of a flat cable are made with connectors having contact elements each with two bifurcate contact members extending to different heights and at right angles to each other from a common base. One contact member contacts a wire of the cable. The other member penetrates the cable parallel to that wire and contacts a connecting wire. Cutting means for severing the cable wire may be included.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
54 words
A connector comprising an insulating base, an insulating cover, and, fixed in said base, folded bi-level twin spring compression reserve U-contact elements having their two bifurcate contact members extending to different lengths in the same direction and from the same edge of a folded base and in planes at right angles to each other.
Claim 2
Dependent Claim
54 words
A connector comprising an insulating base, an insulating cover, and, fixed in said base, folded bi-level twin spring compression reserve U-contact elements having their two bifurcate contact members extending to different lengths in the same direction and from the same edge of a folded base and in planes at right angles to each other.
Claim 3
Dependent Claim
22 words
Connector of claim 1 wherein each of said base and cover is channeled to provide L-shaped cavities for receiving said contact elements.
Claim 4
Dependent Claim
23 words
Connector of claim 2 wherein the top legs of said L-shaped cavities are respectively disposed transversely and longitudinally of said base and cover.
Claim 5
Dependent Claim
27 words
Connector of claim 3 wherein said cover is further channeled to provide centrally of each of said longitudinally disposed legs a transverse channel extending across said cover.
Claim 6
Dependent Claim
29 words
Connector of claim 4 wherein the walls of each said transverse channel are extended inwardly, and the depth of the channel is increased, near each end of the channel.
Claim 7
Dependent Claim
14 words
Connector of claim 1 wherein said base and cover include centrally disposed wire-severing means.
Claim 8
Dependent Claim
14 words
Connector of claim 5 wherein said base and cover include centrally disposed wire-severing means.
Claim 9
Dependent Claim
61 words
Connector of claim 2 wherein said cavities are disposed along the centerlines of said base and cover with the legs of the L each at 45 degrees to said centerline, and wherein each said base and cover includes guide means for permitting the placing of each said base and cover across a flat cable segment at an angle of 45 degrees.
Claim 10
Dependent Claim
63 words
Method of connecting a wire to an individual conductor of a flat cable comprising forcing a folded bi-level twin spring compression reserve U-contact element against said cable with the shorter U-contact making electrical contact with said conductor and the longer U-contact penetrating the cable insulation parallel to said conductor and making electrical contact with said wire lying transversely of and against said cable.
Claim 11
Dependent Claim
63 words
Method of connecting a wire to an individual conductor of a flat cable comprising forcing a folded bi-level twin spring compression reserve U-contact element against said cable with the shorter U-contact making electrical contact with said conductor and the longer U-contact penetrating the cable insulation parallel to said conductor and making electrical contact with said wire lying transversely of and against said cable.
