Definitions

  • the invention relates to a data line with the features of the preamble of claim 1, in particular for use in a motor vehicle and a method for producing such a data line.
  • coaxial cable data line is for example from the US Pat. No. 7,084,343 B1 refer to.
  • the coaxial cable described therein has a central inner conductor, an insulation surrounding this as a dielectric, a multi-layered shielding as an outer conductor and an outer sheath.
  • the multi-layered shield is formed from a longitudinally folded screen foil and a screen braid mounted above it.
  • the coaxial cable is comparatively stiff.
  • this is designed in the manner of a corrugated pipe, as is known in the case of the so-called semi-rigid cables.
  • such a cable is less suitable for use in the automotive sector for cost reasons, especially because of the multi-layer shield structure.
  • One of the biggest cost and time factors is namely the formation of the shield. It is technically used to keep away from the trapped inside the coaxial line disturbing radiation and also for bundling and guiding a propagating field.
  • the shielding is usually made of a braid, more rarely also of a helical shield or a foil screen. In a number of lines, there are also combinations of different umbrella structures. With a braid shield, only slow velocities can be rearranged during production, which lead to a very large machine park on braided machines, which naturally requires a lot of staff, space and energy.
  • Semi-rigid cables are coaxial cables whose outer conductor consists of a closed tube. These lines have excellent electrical properties but are difficult to manufacture, expensive and almost inflexible.
  • a coaxial cable formed in the manner of a semi-rigid cable for use as a transcontinental telephone cable having a corrugated outer conductor formed as an inherently rigid self-supporting tube which encloses an air space to the inner conductor.
  • the outer conductor is multi-layered for cost reasons with a thick steel band and a thin copper band.
  • the ribbed tubular outer conductor has a longitudinal soldering seam.
  • the shield is formed from a longitudinally folded screen foil, which in turn is helically surrounded by ground wires.
  • the screen film itself is two- or three-layered with a plastic carrier film with metal layer applied thereon. This shield construction is relatively expensive to manufacture.
  • From the EP 0 301 859 A is to take a special screen, in which the conductive layer is mounted offset on a support layer, so that the edge part of the conductive layer protrudes beyond the support layer and is folded around this. During wrapping, this folded-over region then comes into surface contact with an end region of the conductive layer in an overlapping region, so that a closed shield layer is formed.
  • the present invention seeks to provide a cost-effective to produce shielded data line with good shielding effect and a method for their preparation.
  • the data line includes a longitudinally extending lead core having at least one conductor surrounded by insulation and surrounded by a multilayer screen foil.
  • the shielding foil is finally surrounded by an outer sheath.
  • the shielding film has a non-conductive layer and a conductive layer, wherein in an overlapping region a free end edge of the shielding film overlaps a further subregion of the shielding film. In the overlapping area, an electrically conductive connection of the conductive layer to the front edge is now formed with the conductive layer in the partial area. The conductive layer is therefore connected at the front edge with the further portion of the conductive layer. As a result, despite the non-conductive layer, a completely circumferential conductive connection is formed within the conductive layer, so that a transverse current flow perpendicular to the longitudinal direction is made possible.
  • the shielding film Due to the multi-layered design of the shielding film, a layer sequence between the conductive layer and the non-conductive layer is given in the case of conventional films in the overlapping region. As a result, interfering high-frequency radiation can occur between the conductive layers due to the non-conductive layer of the screen foil. Due to the configuration with the conductive connection of the free end edge with the other flat partial area, the shielding of the cable is therefore improved compared to a normal overlapping shielding foil.
  • the shielding film is not folded in the overlapping area, ie, in the overlapping area, the ends of the shielding foil lie flat on one another and without folding. In the edge area is therefore no bending or folding the shielding film (by about 180 °) required, which would usually be complicated and thus expensive to implement in the production.
  • This multilayer screen foil is a conventional screen foil having a plastic carrier layer as a non-conductive layer, in particular a PET carrier layer. On this an electrically conductive coating is applied at least on one side. Suitable materials are electrically conductive metals and optionally also electrically conductive carbon compounds. Preferably, a copper layer is used as the conductive layer. Depending on the application, the surface of the copper layer is additionally functionally adapted to desired application conditions of the data line by additional layers, such as tin, silver or even nickel.
  • a three-layered screen film with a central carrier layer is used as the non-conductive layer, on each of which a metallic coating is applied on both sides.
  • a merely two-layered screen foil with a non-conductive layer and a conductive layer can also be used.
  • the individual layers are attached to each other over the entire surface, in particular by a laminating process.
  • the conductive layer therefore covers the non-conductive layer over the entire area and completely.
  • a short-circuit bridge is formed between the front edge and the further subregion. This is formed in particular by a mounted in the region of the front edge conductive strip. This is expediently formed by applying a conductive material by means of a suitable application method, such as, for example, spraying, printing or brushing on. Alternatively, the conductive strip can also be glued on.
  • the outer jacket is applied by means of a (shell) extruder in an extrusion process.
  • this extrusion process is now modified in such a way that the conductive strip is applied immediately before the application of the outer jacket by means of the jacket extruder.
  • a conductive liquid is applied in this case. This has a sufficiently high viscosity that it does not flow off. Additionally or alternatively, it has corresponding fast-drying properties.
  • the applied conductive material is for example a conductive ink, conductive silver or a conductive adhesive.
  • Such methods are used, which allow a continuous order, in particular in the context of a continuous extrusion process.
  • so-called printing wheels are used, the so-called pad printing process or spray and dispensing method used.
  • the conductive strip is applied directly in the extrusion in front of an extrusion head, with the outer jacket is applied in the overlap region.
  • the desired short-circuit bridge is formed by the conductive strip from the front edge to the further flat partial region of the conductive layer.
  • the screen foil itself is modified to form the electrically conductive connection in the overlapping region, specifically such that the conductive layer projects beyond the nonconductive layer at the end edge.
  • a direct contact and thus electrical contact between the projecting portion of the conductive layer and the other portion of the same conductive layer is achieved.
  • the screen foil is beveled at the front edge at an angle. Therefore, in terms of production technology, a conventional, standard-produced film merely needs to be bevelled at an edge region.
  • the oblique front edge is formed for example by a cutting tool, in particular a knife, when cutting the film.
  • the knife is therefore slanted at the desired angle with respect to the film.
  • This angle is - based on a surface normal of the film - preferably more than 30 ° and in particular more than 45 °. Conveniently, the angle is at least 60 °, so that therefore the free end edge is oriented at this angle with respect to one of the surface normals of the screen foil.
  • the chamfering can also be achieved by grinding or scraping initially vertical cutting edges. Improvements in screen attenuation, which are in the range of approximately 5 dB, are to be expected with such oblique front geometries.
  • This method with the beveled on the front edge end foil can be used in principle for all shielded types, ie both for banded shielding foils, which are helically wound around the lead core, as well as for longitudinally applied screen foils, in which the overlap region is parallel to the longitudinal direction.
  • the screen foil is formed as a longitudinally folded film in which the end edge extends parallel to the longitudinal direction.
  • the design is to be preferred in view of high process speeds in the production, as in wound screen films by the winding process is a slowing down of the manufacturing process, which adversely affects the manufacturing cost.
  • the longitudinally folded shielding film and the simultaneous omission of further shield layers, in particular braided shields in addition to the electrically conductive connection on the front edge, the advantages of a tube-like shielding in a semi-rigid cable, with those of a braid shield associated with low production costs.
  • Because of the longitudinally applied film results a closed surface comparable to that of a semi-rigid cable.
  • high flexibility is ensured by the use of a screen foil, which makes the data line suitable for applications with flexural stresses or for applications in which high bending flexibility is desired.
  • the conductive layer of the screen film has a total thickness of preferably less than 50 .mu.m and is in particular in the range of 3 .mu.m to 35 .mu.m. It preferably has a thickness in the range of 20-30 ⁇ m. In principle, thicker conductive layers can also be used, for example up to 100 ⁇ m or up to 200 ⁇ m. However, this increasingly leads to an undesirable stiffening.
  • the thicknesses of the individual layers of the shielding film are usually approximately comparable, wherein often the thickness of the non-conductive plastic carrier layer is greater than the applied by a metal layer conductive layer. The thickness of this metal layer is as mentioned preferably in the range between 20-30 ⁇ m.
  • the total thickness of the shielding film is then preferably about 40 ⁇ m to 80 ⁇ m for a two-layered shielding foil with only one conductive layer and about 50 to 100 ⁇ m for a three-layered shielding foil with two conductive layers.
  • the shielding film is adhesively bonded to the insulation surface, so that therefore the insulation is peripherally completely connected to the shielding film.
  • an adhesive layer is formed, which is formed as an adhesive layer and especially as a hot-melt adhesive layer.
  • this adhesive layer is applied to the screen foil.
  • the adhesive layer is applied to the insulation on the outside. In order to enable this full-surface bonding in terms of manufacturing technology, the adhesive layer is preferably applied during the production process only immediately before the attachment of the screen foil.
  • a heat-activatable hot-melt adhesive layer is applied.
  • This alone by the in the subsequent coat extrusion introduced heat is activated, ie the screen foil is glued to the insulation.
  • the bonding is therefore carried out directly during the extrusion process.
  • the screen foil is reliably fixed in the desired position.
  • Another advantage is the fact that just the overlap point at which the individual portions of the film rest against each other, are fixed together.
  • the electrical contacting of the screen foil with a contact element is not readily possible due to the low rigidity of the screen foil.
  • Conventional contacting operations such as crimping, can not be used.
