Definitions

  • the present invention relates to a cable high frequency transmission, of the type comprising individually insulated and assembled electrical conductors in several beams often protected by shielding, and comprising an overall protective outer sheath.
  • Such cables are used in particular in the IT domain for high frequency transmission of data, which can be of the order of 100 MHz. They are often of flat exterior shape.
  • the bundles of insulated conductors can be pairs, thirds or fourths. They can also be assembled in at least a set. Conductors isolated from bundles of the same together are then advantageously assembled with steps different for the constitution of the different bundles of this set.
  • the shield then surrounds each set of bundles.
  • each set can be made by an insulating tape, by example in polyester, the outside of which is metallic.
  • This ribbon is laid lengthwise or helically covering of its edges, around the whole of bundles.
  • Document Wo-A-86/05311 describes a flat cable computer in which isolated conductors individually are assembled in pairs protected by a individual shielding screen, these insulated conductors being all positioned in the same plane.
  • two insulated conductors positioned side by side are assembled in a pair by a first insulating coating extruded around of these two insulated conductors and thus embedded in it.
  • Each pair is protected by a metallic tape of shielding surrounding it.
  • Protected pairs positioned side by side side by side are assembled by a second insulating coating extruded around them, forming the outer sheath of overall cable protection.
  • the first coating is made of polyvinyl chloride, non-adherent on the insulation of the conductors made of polyethylene or propylene.
  • Document US-A-4,755,629 describes an electric cable high frequency transmission.
  • this cable has two pairs of insulated electrical conductors individually, a dielectric rod for joining the two pairs while separating them from each other, a screen of shielding around the rod and a protective sheath outside.
  • This ring is of cross section in the shape of an eight to define two cavities for the two pairs and one spacer between these pairs and has two opposite slots opening along the cavities. These slots allow insertion of the pairs in the cavities and facilitate access to each pair for mounting a connector cable terminal. However, they can lead to deformations of the cavities and then displacements of the pair conductors in place, despite the presence of shield covering the periphery of the rod.
  • the object of the present invention is to produce a cable high frequency avoiding the drawbacks of realizations known above and allowing to reach levels of crosstalk on the order of -40 to -50 dB at 100 MHz.
  • Its purpose is a high transmission cable frequency, with insulated electrical conductors individually and assembled into several bundles themselves assembled in at least one set, a rod dielectric for assembling the bundles of each set and an overall protective outer sheath, said rod dielectric having contiguous tubular portions defining on the one hand longitudinal cavities independent, assigned to the bundles of the same assembly, each section adapted to that of one of the bundles of this set and each provided with a slot on the periphery of the rod for the placement of the beam in the cavity, and on the other hand at least one zone common to the tubular portions and said spacer between the bundles in place in the cavities, characterized in that it comprises a closed holding element of each of said slots of different cavities containing the beams, for a continuity of dielectric material around the beams place in said cavities and a conservation of the geometry of said beams in place.
  • the single figure is a sectional view a high frequency transmission cable, according to the invention.
  • This cable is flat and has two quads 1. Each quart is made up of a twist of four solid conductors 2, in particular copper, each coated with insulation 3 in PE or PP preferably.
  • the dielectric rod 5 has for this purpose two cavities 6 in length receiving these two quarters.
  • Each of these cavities is of circular section, adapted to that of quartets 1. It is opened by a narrow slot 7 on the periphery of the rod, initially or at the installation of the fourth.
  • This slot is wide very weak, a few tenths of a millimeter or more advantageously of the order of a few hundredths of millimeter only, for later closing.
  • This dielectric rod 5 is an extruded profile, produced preferably polyethylene or polypropylene. He's from substantially elliptical section, for a flat shape desired cable, with its two cavities and their slots centered on the major axis of its section. He plays the role spacer for maintaining and separating the two quarters. Her central area between the two cavities is thick minimum of at least 0.2mm and is preferably of the order of 0.3mm for 1.3mm diameter insulated conductors about.
  • the cable further comprises a shielding screen 8, in the form of a ribbon laid lengthwise and overlapping its edges around the dielectric rod and the two fourths as well assembled, and a screen continuity wire 9, interposed between the screen and the dielectric rod.
  • This screen can be metallic or be dielectric and then metallized and in particularly aluminized. It ensures the closed maintenance of slots in the various cavities of the rod it surrounds.
  • This set of two quarters thus protected is covered with an outer sheath 10 of overall protection.
  • This sheath ensures a tight hold of the screen around the rod whose cavities are thus closed. It is extruded directly on the screen as soon as it is installed.
  • She can be made of PE, PP or preferably PVC or other material cladding classic.
  • this cable is quick and simple. She is done on a manufacturing line not shown, comprising means for scrolling the rod, two sets spacers fitting into the slots in the rod cavities for their opening by elastic deformation, means of guidance and insertion of the two quartes into the cavities open rod, means for guiding the continuity wire screen against the rod, guiding and setting means place shielding tape around the rod and a die extrusion end of the outer protective sheath.
  • the rod may have a section other than that substantially elliptical, being without sharp peripheral edge. It can also include more than two longitudinal cavities, each of section adapted to the section of the beam to be mounted, the beams assembled in the rod which can be quads and / or third parties and / or pairs.
  • the slots of the different cavities can be relatively large. They are then closed by a dielectric gasket attached and retained in each of them or by an external dielectric tape surrounding the rod or by the dielectric layer shielding screen of preferably reinforced thickness.
  • This dielectric rod cable for holding and separation of the bundles from each set can also be without shielding screen.
  • the cable may include several rods surrounded or not by their individual screen of shielding and retained side by side in an outer sheath extruded around them.
