Abstract
Abstract A tape cable structure includes several sets of twisted wire pairs which are laminated so that the twist points are in a fixed phase relation with each other. In one embodiment, even twist length ratios between the adjacent twisted pairs are used. The relationship between the twist points can be adjusted to permit mass termination of the cable. When severed as by a heat knife along a transverse section of the tape at which the twists of all pairs are in phase, the two tape sections are drawn apart to expose substantially parallel bare wires ready for connection.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
103 words
A tape cable comprising: a longitudinally continuous insulative compliant tape medium; a plurality of plastic insulated conductor pairs attached along generally parallel paths to said medium, each pair having a predetermined different twist length, the twist lengths being selected to create at periodic transverse positions along said medium an in-phase relationship among all said twisted pairs; said medium being capable of being severed along any one of said transverse sections and the severed parts drawn apart with the tape medium and said plastic conductor insulation mutually adhering, thereby to expose a zone of bare wires spaced apart, substantially parallel and ready for connection.
Claim 2
Dependent Claim
103 words
A tape cable comprising: a longitudinally continuous insulative compliant tape medium; a plurality of plastic insulated conductor pairs attached along generally parallel paths to said medium, each pair having a predetermined different twist length, the twist lengths being selected to create at periodic transverse positions along said medium an in-phase relationship among all said twisted pairs; said medium being capable of being severed along any one of said transverse sections and the severed parts drawn apart with the tape medium and said plastic conductor insulation mutually adhering, thereby to expose a zone of bare wires spaced apart, substantially parallel and ready for connection.
Claim 3
Dependent Claim
25 words
A tape cable pursuant to claim 1 wherein said tape medium comprises first and second sheets laminated together with said plurality of pairs sandwiched thereinbetween.
Claim 4
Dependent Claim
26 words
A tape cable pursuant to claim 2 wherein said tape medium further comprises edge notches placed at the positions of said transverse sections for identification thereof.
Claim 5
Dependent Claim
31 words
The apparatus of claim 1 in combination with a connector element comprising a row of spaced upright metallic pins, the spaced-apart conductors of each said pair straddlIng a respective said pin.
Claim 6
Dependent Claim
30 words
A tape cable pursuant to claim 1, wherein said in-phase relationship is represented by a maximum mutual separation between the conductors of each pair occurring concurrently at said transverse positions.
