Definitions

  • the invention is based on the object of specifying a cable for electrical signal transmission, which is connected to a Stripping and cutting tools can be safely completed in one operation so that the internal wires can be exposed without damage.
  • commercially available stripping tools should be used, the knives of which enable a radial cut around the outer sheath of the cable with an adjustable penetration depth.
  • the object is achieved with a cable specified in claim 1.
  • This has the advantage that the cavities between the usually stranded wires and the cylindrical outer jacket around them are very evenly foamed with a so-called inner jacket made of easily extrudable polyvinyl chloride.
  • This in turn has the consequence that the inner conductors and in particular their wire insulation in all radial and longitudinal regions of the cable lie at a uniform depth below the outside of the outer cable sheath.
  • the penetration depth of radially cutting stripping tools can consequently be set so precisely that the outer jacket regions of the cable can be cut in a single operation without the risk of local damage to wire insulation.
  • Corresponding additives can cause the polyvinyl chloride to form an inner jacket after curing, which has only limited adhesion to the first and any second separating layer that may be present. Such additives can also be used to create an inner jacket which has only limited tensile strength. Finally, by corresponding Additives are caused that the inner jacket has a certain fragility. All of these measures make it possible, in the event that, after the use of an incisive stripping tool, there are still remnants of the inner sheath surrounding the inner wires, to remove these parts without effort and without further use of tools, for example by tearing them off.
  • the cable 1 shown in cross-section in the figure serves for the transmission of electrical signals and for this purpose has at least one pair of wires 11 and 15 lying next to one another.
  • the wires can each be copper stranded wires, which are stranded against each other.
  • Each core 11 and 15 also has a separate core insulation 13 and 15. This can preferably consist of a so-called Zeil - polyethylene dielectric.
  • an inner jacket 9 made of easily extrudable polyvinyl chloride is now extruded around the first separating layer 21 in such a way that a structure with an outer contour that is circular in cross section is produced.
  • the circular shape of the outer contour is extremely precise.
  • the unit made of the pair of wires surrounded by the separating layer 21 is extrusion-coated very uniformly with the inner jacket 9 made of polyvinyl chloride.
  • a screen braid 5 is also preferably made of tinned copper tissue ring-shaped around the inner jacket 9 and finally an outer cable jacket 3 preferably made of polyvinyl chloride ring-shaped around the screen braid 5.
  • the cable 1 can advantageously have a second separating layer 7, which is placed in a ring around the inner jacket 9 and is surrounded by the braided shield 5. This preferably consists of a metallized polyester film.
  • the circumferential cutting line resulting from the use of a radially cutting tool with an optimally set penetration depth of the cutting knife is shown in the form of a dashed circle 23. It can be seen that not only the outer cable jacket 3, the shielding braid 5 and the second separating layer 7 can be completely severed in one operation. Rather, the inner jacket 9 made of easily extrudable polyvinyl chloride can also be cut precisely, particularly at its narrowest web areas 25 and 27. A violation of the underlying wire insulation 13 and 17 in particular is avoided with certainty.
  • the structure of the inner casing 19 has already been weakened by the cuts in the web areas 25 and 27 in such a way that it can be removed in the form of two halves with the least effort. If the polyvinyl chloride of the inner jacket 9 is still mixed with appropriate additives, so that the adhesion of the inner jacket to the first and / or the second separating layer 21, 7 is restricted and the inner jacket 9 has a reduced tensile strength and at the same time increased brittleness, this can be easily removed. With a corresponding setting of the cutting depth of a stripping tool, the case may even occur that the inner sheath falls off automatically after removal of the outer area of the cable and a slight torsion of the wires 12, 15.
  • Another advantage of the cable structure according to the invention is seen in the fact that in practice there are no changes in the so-called “electrical climate” inside the cable according to the invention in comparison to conventional cable structures.
  • the essential electrical characteristic values of the cable such as, for example, Shield, insulation and wave resistance, wave attenuation, operating capacity, earth coupling, operating voltage, test voltage and the like are unchanged in comparison to cables which, instead of an inner jacket made of easily extrudable polyvinyl chloride, have rope-like fillings.

Abstract

Le câble (1) comprend au moins une paire de brins (11, 15) dotés d'une isolation (13, 15). Une première couche de séparation (21) entoure l'isolation. A cet effet, une gaine interne (9) est posée sans espace vide de façon à obtenir une structure dont le contour extérieur en coups transversale a une forme annulaire. Enfin, un tressage de blindage (5) et une gaine externe (3) sont posés en cercle autour de la gaine interne. Ce câble offre l'avantage que les brins puissent être dénudés rapidement et sans dommage à l'aide d'outils coupants par dénudage de la gaine externe, du tressage de blindage et de la gaine interne.
