Definitions

  • the invention relates to a method for producing adhesive-free flat-conductor ribbon cable as well as flat conductor ribbon cable produced in this way.
  • Flat conductor ribbon cables are widely used in the electrical and electronics industry. They can be used for example for connecting electrical components, as control signal or energy transport lines or as flexible heating elements.
  • Flat conductor ribbon cables have a plurality of conductor tracks, which are spaced apart from each other and arranged parallel to each other in a plane.
  • the tracks are embedded in a polymer that isolates the tracks from each other and against the environment while protecting against damage.
  • Flat conductor ribbon cables are mainly used for the transmission of electrical energy and / or data in the form of electrical signals.
  • the uses of a ribbon cable are largely determined by the properties of the polymer used for the isolation and by the method by which the tracks are embedded in the polymer.
  • the properties of the polymer in particular its temperature resistance, dynamic bending fatigue strength, its buckling behavior, its tear and tear propagation resistance, its burning behavior, its resistance to media and hydrolysis, and its dielectric strength are therefore subject to special requirements, depending on the particular application of the cable.
  • the process used to make the ribbon cable has a significant influence on its characteristics.
  • the dielectric strength of the flat conductor ribbon cable is determined not only by the electrical breakdown strength of the polymer, but also by the method used.
  • Flat conductor ribbon cables are usually produced by sealing the parallel conductor tracks in the polymer, for example polyethylene terephthalate, with the aid of an adhesive.
  • FFC Flexible Flat Cabels
  • the parallel conductor tracks are laminated with polymer films in such a way that the conductor tracks are located between the polymer films.
  • FPC Flexible Printed Circuit
  • the printed conductors are vapor-deposited on a polymer film or applied by means of a galvanic process. A second polymer film is coated on the first polymer film thus obtained, wherein both polymer films are bonded together with an adhesive previously introduced between the two polymer films.
  • thermoplastics consist of monomers containing aromatic or heteroaromatic groups.
  • Flat conductor ribbon cables were made according to the examples only with insulation of polyethersulfone, polysulfone and polyetheretherketone. These polymers were used in the form of films. For this purpose, for example, a granulate is melted in an extruder, the melt is extruded through a die and then cooled the melt in a water bath or on a casting roll. Two of the films thus obtained are then pressed to produce flat conductor ribbon cables with the conductor tracks. However, in this way no complete and uniform covering of the interconnects can be ensured since the formation of cavities can not be completely ruled out.
  • a serious problem of this method is that required for hot pressing heat in the conductor tracks is removed from these, so that in the immediate vicinity of the interconnects no optimal bonding of the films to the conductors can be achieved.
  • capillary forces thus media can penetrate into the cable and the tracks to damage. Consequently, the flat conductor ribbon cables produced by this method do not exist the so-called capillary test.
  • EP 0 938 099 discloses a method for producing flat cables.
  • parallel conductors are guided with a rectangular cross-section to a crosshead of an extruder and there extrusion-coated with a thermoplastic resin having a flexural modulus of 800 to 2400 MPa.
  • Suitable thermoplastic resins include polyamide resins, polyolefin resins, and sea-island structure polymers.
  • this method is not suitable for producing flat conductor ribbon cables, the polymeric insulation of which meets high demands on the dielectric strength and dimensional stability.
  • the adhesive-free flat conductor ribbon cable according to the prior art thus do not meet the high demands that are made especially in recent years on flat conductor ribbon cables in the industry, for example in the automotive industry.
  • the object of the invention is to eliminate the disadvantages of the prior art.
  • a method for producing adhesive-free flat-conductor ribbon cable with high dimensional stability and thus high electrical withstand voltage is to be specified.
  • a device for producing such a flat conductor ribbon cable and a flat conductor ribbon cable with high dimensional stability and thus high electrical voltage resistance should be specified.
  • step (d) the plasticized polymer and the parallel flat conductors are passed together through a die of the tool, whereby the parallel flat conductors are completely embedded in the plasticized polymer to form an insulating layer which sheathes the leads.
  • the method is a method for the continuous production of flat conductor ribbon cables.
  • the invention is thus based on the finding that the production of a constant volume flow, with which the plasticized polymer is supplied to the tool, leads to a polymeric insulation of the leads, which is much smaller in size compared to the prior art.
  • the higher dimensional stability which in itself is a significant advantage of the method according to the invention, moreover leads to better properties of the flat conductor ribbon cable, in particular to a better electric voltage resistance.
  • the flat conductor ribbon cables produced in this way thus meet the requirements that have been considerably tightened in the last two years, for example the automotive industry to the flat-conductor ribbon cable she uses.
  • the flat conductors used should have a rectangular cross-section.
  • the flat conductors may be metallic conductor tracks, which are formed for example from copper.
  • trace and “flat conductor” are used interchangeably.
  • providing the extrudable polymer comprises drying the polymer.
  • the drying time may be between 30 minutes and 4 hours and the drying temperature between 50 and 160 ° C.
  • any polymer which is extrudable can be used in the process according to the invention.
  • the polymers polyethersulfone, polyetherimide, polyethylene naphthalate, polypropylene and derivatives of these polymers or blends containing these polymers and / or derivatives of these polymers are preferred. It is particularly preferable to use polyethersulfone as the polymer.
  • the constant volume flow of the plasticized polymer can be adjusted with a melt pump. With the aid of this melt pump, the discontinuous ("pulsating") volume flow is converted into a constant volume flow.
  • the constancy of the volume flow can be checked by means of pressure measurements. At a pressure of the volume flow of the plasticized polymer leaving the extruder of 50 MPa the pulsating pressure differences are ⁇ 5 MPa. If this volume flow were used directly to coat the conductor tracks, insulation with a small dimensional stability would be obtained, and in the case of polymers such as polyethersulfone even an insulation surface with a flaky character (so-called melt fracture) would be obtained. The electrical withstand voltage of this flat conductor ribbon cable is accordingly low.
  • the volume flow is constant, with the exact parameters depending on the melt pump used. "Constant" in this context means that the volume of the continuous volume flow, which is supplied to the tool, varies by a maximum of ⁇ 2.5% per unit time.
  • the performance of the extruder can be controlled by a suitable pressure control, which has a sensor between the outlet of the extruder and the melt pump.
  • Merging the constant volume flow of the plasticized polymer with the parallel flat conductors in step (d) should involve adjusting the location of the tracks in the polymer.
  • the conductor tracks are guided vertically in the tool.
  • the flat-conductor ribbon cables obtained in step (d) should be cooled after leaving the tool in which the plasticized polymer and the conductor tracks are brought together. This can be done for example by the flat-ribbon cable is passed through a temperature-controlled water bath and / or a cooling medium.
  • This device is particularly suitable for carrying out the method according to the invention.
  • the means for providing an extrudable polymer comprises a dryer for drying the extrudable polymer.
  • the wire guide preferably leads the parallel flat conductors vertically through the tool.
  • the vertical guide of the flat conductor has the particular advantage that the effects of gravity on the insulating material are avoided, the horizontal guide, as described in the cited prior art, to different thickness of the insulation on the top and bottom of the flat-ribbon cable leads.
  • the device expediently comprises means for cooling the flat conductor ribbon cable obtained in the tool.
  • This device may be a tempered water bath and / or a cooling medium.
  • the apparatus for the continuous production of flat conductor ribbon cables with high dimensional accuracy comprises an extruder 5, in which the extrudable polymer is plasticized.
  • the plasticized obtained in this way Polymer is fed with a volume flow through a screen changer 7 to a melt pump 8.
  • screen changer 7 impurities are removed from the plasticized polymer.
  • melt pump 8 With the melt pump 8, a constant volume flow is produced from the pulsating volume flow of the plasticized polymer leaving the extruder 5.
  • This constant volume flow of the plasticized polymer impinges in the tool 9 on the conductor tracks 2 which are guided parallel to one another and pass vertically through the tool 9 (FIG. 2).
  • the vertical direction of the flat conductor is achieved by means of deflection roller 8, which is arranged above the tool 9.
  • the conductor tracks 2 in wire guide 11 are continuously guided (Fig. 3).
  • the plasticized polymer enters the tool 9 via the material inlet 15 (FIG. 4). From there, the plasticized polymer is conducted via a material deflection 14 (so-called deflection device) into the polymer guide 16, where it meets the conductor tracks, as shown in detail A of FIG. 3. Subsequently, the conductor tracks encased in the polymer leave the tool 9 via the outlet nozzle 12 (FIG. 2, FIG. 4) and are passed through a water bath 10.

  • the cross section of the guide channel 111 narrows from the inlet opening 112 in the direction of the outlet opening 113.
  • the arrangement of the outlet openings 113, in particular their distance from one another, is determined by the intended arrangement of the flat conductor 2 in the flat-ribbon cable 1 to be produced.
