Abstract
Abstract The high frequency transmission cable comprises insulated conductors assembled together in bundles which are themselves assembled together in at least one unit, and also comprising an outer sheath for overall protection. It further comprises a dielectric rod that is grooved lengthwise for assembling together the bundles in each unit, the grooves of the rod being open via respective slots and serving to hold individual bundles while keeping them apart from one another. The cable is particularly suitable for use as a computer cable.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
102 words
A high frequency transmission cable comprising individually insulated electric conductors assembled together in a plurality of bundles that are themselves assembled together in a unit, together with an overall protective outer sheath, the cable further including a grooved dielectric rod for assembling together the bundles in the unit, the rod being provided with longitudinal, non-communicating grooves each having a cross-section sized to accommodate a cross-section of a corresponding one of the bundles and each being open via a slot to the periphery of the rod, in which the bundles of the unit are held individually while being kept separate from one another.
Claim 2
Dependent Claim
102 words

Claim 3
Dependent Claim
25 words
The cable according to claim 1, wherein said rod is made of a material selected from the group consisting of: polyethylene, propylene, and copolymers thereof.
Claim 4
Dependent Claim
48 words
The cable according to claim 1, wherein said rod is of elliptical right cross-section and includes at least two of said diametrically opposite grooves both centered on the major axis of the elliptical section, with the slots thereof being respectively located at the ends of said major axis.
Claim 5
Dependent Claim
34 words
The cable according to claim 1, wherein said grooves are circular in section, being deformable by opening the slot of each of them, for the purpose of receiving a corresponding one of said bundles.
Claim 6
Dependent Claim
39 words
The cable according to claim 1, wherein said rod has a central zone forming a dielectric spacer between the bundles held in its grooves, and having a minimum thickness lying in the range of 0.3 mm to 0.5 mm.
Claim 7
Dependent Claim
29 words
The cable according to claim 1, wherein said slots are narrow, being of substantially zero width in that the width is less than a few tenths of a millimeter.
Claim 8
Dependent Claim
17 words
The cable according to claim 1, further including an element for closing the grooves containing said bundles.
Claim 9
Dependent Claim
28 words
The cable according to claim 1, wherein the bundles of the unit are constituted by two to four twisted-together conductors that are thus held directly in the grooves.
Claim 10
Dependent Claim
41 words
The cable according to claim 1, further including a screen placed around the unit with the edges of the screen overlapping, wherein the screen surrounds said dielectric rod, and the mutually overlapping margins of said screen are offset from the slots.
Claim 11
Dependent Claim
35 words
The cable according to claim 1, wherein said rod has a central zone forming a dielectric spacer between the bundles held in its grooves, and having a minimum thickness of not less than 0.2 mm.
Claim 12
Dependent Claim
31 words
The cable according to claim 1, wherein said slots are narrow, being of substantially zero width in that a width is on the order of a few hundredths of a millimeter.
