Definitions

  • a coaxial cable As is well known in cable technology, there are coaxial cables that are used when higher-frequency signals are to be transmitted.
  • a coaxial cable according to DE-OS-2.537.873 has an inner conductor and an outer conductor. There is a dielectric between the inner conductor and the outer conductor.
  • the inner conductor is, for example, a tube or a solid wire.
  • the outer conductor is, for example, a tube which is arranged coaxially with the inner conductor.
  • the outer conductor and inner conductor can be made of copper or aluminum, for example.
  • the dielectric can, for example, fill the entire space between the inner conductor and the outer conductor. In this case, the dielectric has the shape of a tubular body.
  • disk-shaped bodies as dielectric which are located on the inner conductor and are arranged at a distance from one another.
  • plastics such. B. polyethylene.
  • the outer conductor is surrounded by an outer jacket or protective jacket.
  • the invention is based on the knowledge that, in the case of known cables, when they are bent, ridges or corrugations arise which have to be smoothed out again when fittings are to be attached.
  • the invention has for its object to provide a coaxial cable which does not have this disadvantage and which avoids the formation of beads. This object is achieved by a coaxial cable with the features of claim 1.
  • the invention is preferably applied to a coaxial cable which has a grid belt to increase the tensile strength, which consists, for example, of glass or glass fiber bundles.
  • FIG. 1 shows a preliminary product of a coaxial cable, which consists of an inner conductor 1, a dielectric 2 and an outer conductor 3.
  • an adhesive layer 4 is applied to the outer conductor 3 of the arrangement of FIG. 1 and then an outer jacket 5 is extruded onto the arrangement of FIG. 2 according to FIG.
  • the adhesive layer 4 ensures that the outer conductor 3 is glued to the outer jacket 5 in the finished coaxial cable of FIG. 3.
  • FIG. 4 shows an exemplary embodiment of the invention, in which a tubular body 7 is produced from an adhesive tape 6 and is then applied to the arrangement in FIG. 1 in accordance with FIG.
  • a grid-shaped, tubular body 8 which is produced from a grid belt, is applied to the tubular body 7 in the same way as the tubular body 7.
  • the tubular body 8, which consists, for example, of glass bundles, increases the Tensile strength of the coaxial cable.
  • FIG. 7 shows the finished coaxial cable with the outer jacket 5, which is extruded onto the arrangement of FIG. 6, for example.
  • the figure's coaxial cable 7 the essential condition is met that the outer jacket 5 passes through the grid body 8 on the adhesive layer.
  • Figures 8 and 9 show a further embodiment of the invention, in which no separate adhesive layer or adhesive body is used, but in which 8 adhesive material is applied to the inner surface of the lattice body provided, so that on a separate adhesive layer on the outer conductor or on a separate adhesive body can be dispensed with in this case.
