Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
155 words
A method of preparing the end of shielded flat multiconductor cable for termination, the cable comprising a plurality of side by side insulated conductors in a coplanar array surrounded by a conductive shield which is surrounded by a continuous insulative outside jacket, the cable having opposed side edges and opposed flat external surfaces extending therebetween, the method comprising the steps of, simultaneously cutting the opposed edges of said cable in the plane of the conductors between said end and a predetermined distance therefrom, said cutting being accomplished by a pair of cutting blades which penetrate the outside jacket and said shield, cutting into the opposed flat external surfaces transversely of the cable at substantially the predetermined distance from said end, said cutting substantially penetrating said outside jacket without cutting said shield, removing the outside jacket for said predetermined distance from said end, folding the shield so exposed back against the outside jacket of said cable.
Claim 2
Independent Claim
155 words
A method of preparing the end of shielded flat multiconductor cable for termination, the cable comprising a plurality of side by side insulated conductors in a coplanar array surrounded by a conductive shield which is surrounded by a continuous insulative outside jacket, the cable having opposed side edges and opposed flat external surfaces extending therebetween, the method comprising the steps of, simultaneously cutting the opposed edges of said cable in the plane of the conductors between said end and a predetermined distance therefrom, said cutting being accomplished by a pair of cutting blades which penetrate the outside jacket and said shield, cutting into the opposed flat external surfaces transversely of the cable at substantially the predetermined distance from said end, said cutting substantially penetrating said outside jacket without cutting said shield, removing the outside jacket for said predetermined distance from said end, folding the shield so exposed back against the outside jacket of said cable.
Claim 3
Dependent Claim
31 words
The method of claim 1 wherein the cutting of said opposed edges is accomplished by feeding the end of said cable between a pair of rotary cutting blades having stationary axes.
Claim 4
Independent Claim
150 words
An apparatus for preparing the end of a shielded flat multiconductor cable for termination, the cable comprising a plurality of side by side insulated conductors in a coplanar array surrounded by a conductive shield which is surrounded by a continuous insulative outside jacket, the cable having opposed side edges and opposed flat external surfaces extending therebetween, the apparatus comprising, guide means defining an axial feed path for said cable, said guide means confining said cable against movement transversely of its axis in the plane of the cable, a pair of cutting blades flanking said feed path on opposite sides thereof, said blades being arranged to cut the opposed edges of said cable in the plane of the conductors, said blades being arranged to penetrate said outside jacket and said shield, confining means for restricting said cable against movement transverse to the plane thereof in the vicinity of the cutting blades.
Claim 5
Independent Claim
150 words
An apparatus for preparing the end of a shielded flat multiconductor cable for termination, the cable comprising a plurality of side by side insulated conductors in a coplanar array surrounded by a conductive shield which is surrounded by a continuous insulative outside jacket, the cable having opposed side edges and opposed flat external surfaces extending therebetween, the apparatus comprising, guide means defining an axial feed path for said cable, said guide means confining said cable against movement transversely of its axis in the plane of the cable, a pair of cutting blades flanking said feed path on opposite sides thereof, said blades being arranged to cut the opposed edges of said cable in the plane of the conductors, said blades being arranged to penetrate said outside jacket and said shield, confining means for restricting said cable against movement transverse to the plane thereof in the vicinity of the cutting blades.
Claim 6
Dependent Claim
21 words
The apparatus of claim 3 which further comprises stop means on said feed path a predetermined distance beyond said cutting blades.
Claim 7
Dependent Claim
13 words
The apparatus of claim 3 wherein said cutting blades are rotary cutting blades.
Claim 8
Dependent Claim
31 words
The apparatus of claim 5 wherein said rotary cutting blades have stationary axes, the blades being spaced to impinge the opposed edges of said cable moved therebetween on said feed path.
Claim 9
Dependent Claim
27 words
The apparatus of claim 3 wherein said confining means comprises resilient clamping means which bears against opposed flat surfaces of said cable without preventing axial movement thereof.
