Definitions

  • the invention relates to a data cable with at least two each stranded cable harnesses, each individually consisting of two Cables are twisted into a cable harness and that of each other be kept spaced.
  • the invention relates to a Method for manufacturing such a data cable.
  • Such a data cable is, for example, from US-A-5,789,711 known and has a star-shaped core element, on which radial a shield and a shield are attached to the outside surrounding outer jacket are provided.
  • the star-shaped Together with the shielding, the core element forms four chambers, in which each have a cable harness made up of two twisted together Single cables are provided.
  • Such a data cable is intended in particular also for modern applications, such as Gigabit Ethernet, be suitable.
  • the invention is based on the basic idea that one generic data cable by sufficient fixation of the stranded cable strands an improvement in the transmission properties can be achieved compared to known data cables.
  • a exact position fixation is, for example, with the previously described Star-shaped core according to the prior art is not possible because the individual cable harnesses in their chambers are relatively free in their position or can choose their position. In particular, this position also by relatively little external intervention, for example when bending the cable, change. As a result, the relative position varies of the wire harnesses to each other, thereby reducing the transmission behavior is adversely affected.
  • the invention strikes Data cable with at least two stranded cable strands each individually in each case from at least two cables to one Harness are stranded and by at least one plastic deformable central element are kept spaced apart.
  • a plastically deformable central element adapts position of the individual cables of each cable harness and can in this way the two stranded cable strands are extremely precise position.
  • the stranded cable strands are basically can include any number of individual cables. Preferably it is a pair or four stranded wires. these can be designed symmetrically. Each of the individual cables is preferably composed made of polymer-insulated copper wires.
  • a data cable according to the invention can, for example, thereby manufacture that first through at least two individual harnesses respective stranding of at least two individual cables generated and along be positioned to each other, then between each A central element is introduced, which during the Positioning the cable strands is plastically deformed.
  • plastic deformation refers to the present Context a material that is at least under in the making occurring conditions is plastically deformable.
  • the central element even under normal Operating conditions of the data cable is plastically deformable. It can for example, find a thermoplastic used in the Cable production is heated accordingly.
  • the central element can be the point in time at which this is plastically deformed and the cable harnesses are positioned appropriately. So can, for example, the central element already when merging the Cable harnesses and the central element in its plastically deformable Condition. Also, the central element can only after the Cable harnesses are positioned on the same, in its plastic state brought, whereby the cable harnesses and the central element reach its final position.
  • the latter Procedure has the advantage that the central element easily in the stranding can be introduced before it is in its plastic Condition and thus becomes unstable.
  • the invention also proposes a data cable at least two stranded cable strands, each individually in stranded from at least two cables to form a cable harness and which are kept apart from each other a central element is provided between the cable harnesses Diameter varies over the cable length and / or which in Cross-section has radial formations, the width of which over Cable length varies.
  • the central element does not necessarily have to be centered between the Cable harnesses should be arranged.
  • several can Central elements are provided.
  • Central element as a dummy element is not an active part of the data cable is.
  • the central element can also have active components, such as conductive properties, a central light guide or the like, exhibit.
  • a core can be provided in the central element.
  • This soul can serve, for example, a strain relief. It is also possible for the soul to be selected such that they include the plastically deformable central element in radial direction stabilized so as to fix its task support.
  • the soul can also serve other purposes and for example also include a light guide.
  • a copper wire can be provided as a core.
  • the data cable can have at least one spacer with exactly two Cable strands are in contact and hold them. Through a or several such spacers can have the positioning effect of the plastically deformable central element. In particular, it is possible to place these spacers in the outer Gussets between two stranded cable harnesses.
  • the Spacers can for example have a circular cross section exhibit. On the other hand, it is also possible to do this essentially To give a gusset shape.
  • the spacers can be rigid on the one hand or elastic or, on the other hand, also plastically deformable his. Because the spacer only has exactly two Cable harnesses in contact, it can determine the exact location of the adapt each individual cable and in this way in excellent Have a stabilizing effect.
  • the central element and / or at least one Spacers can be glued to at least one cable harness.
  • the position of the cable harness can also be fixed become.
  • Such gluing should not be confused with one Connection of the individual cables of a cable harness to each other.
  • an adhesive bond is also independent of the Central element advantageously a fixation of the cable harness or Cable harnesses serves.
  • an im essentially rigid or elastically deformable central element can be used together with an adhesive.
  • central element and / or the or Spacers designed to be conductive or with a conductive layer are provided. This makes it possible, regardless of the others Features of the invention, the quality of a data cable in terms improve its crosstalk behavior and the like.
  • such data cables are surrounded by an outer jacket.
  • an outer jacket which has a cable core made of cable strands and, if appropriate, surrounds central elements or spacers, to be dispensed with.
  • the jacket can be chosen such that he applies the necessary radial internal forces that lead to an inventive Fixation are necessary. This can be especially in the Connection with one or more plastically deformable central elements be beneficial.
  • this outer jacket touches when viewed in cross section none of the assemblies contained in the core are over 90 degrees outgoing angles, like this one with the star-shaped one, above described arrangement according to the prior art is the case in which is spaced 90 degrees apart at an angle of 360 degrees in contact with the jacket. In this way avoid unwanted force compensation according to the invention, and the forces applied by the jacket can be used to fix the Assemblies of the core serve.
  • One or more can be between the outer jacket and the core wound tensioning foils can be provided.
  • Such a winding relatively large radial forces can be applied, by which the assemblies of the core can be fixed. Depending on the specific These forces can be created by the outer jacket forces that can be applied are several times greater.
  • Such Tension film can be a polymer film, for example.
  • such a wound stretch film also regardless of the other features of the data cable advantageous Can be used.
  • such a stretch film also with elastic central elements or only in connection can be used advantageously with spacers.
  • the assemblies used for the core including adhesive as well the tension film can have a lower dielectric constant depending on the requirements have than the outer jacket.
  • the dielectric constant chosen less than 2.3.
  • the Materials are chosen such that migration between them is avoided as far as possible or takes place under controlled conditions.
  • the core can alternatively or cumulatively be provided with a shield his.
  • a shield his can be, for example, a metal foil or a metallic one coated foil or a metal braid. This can e.g. between the core and an outer jacket.
