Definitions
- the invention relates to a method for producing adhesive-free flat conductor ribbon cables and flat conductor ribbon cables produced in this way.
- Flat conductor ribbon cables are used extensively in the electrical and electronics industry. They can be used, for example, to connect electrical components, as control signal or energy transport lines or as flexible heating elements.
- Flat conductor ribbon cables have several conductor tracks, which are spaced apart from one another and are arranged parallel to one another in one plane.
- the conductor tracks are embedded in a polymer that insulates the conductor tracks from one another and from the environment and at the same time protects them from damage.
- Flat conductor ribbon cables are mainly used to transmit electrical energy and / or data in the form of electrical signals.
- the possible uses of a flat conductor ribbon cable are largely determined by the properties of the polymer used for insulation and by the method by which the conductor tracks are embedded in the polymer.
- the properties of the polymer especially its temperature Resistance to turbulence, dynamic flexural fatigue strength, its kinking behavior, its resistance to tearing and tear propagation, its burning behavior, its resistance to media and hydrolysis and its dielectric strength must therefore be subject to special requirements depending on the particular application of the cable.
- the process used to manufacture the flat conductor ribbon cable significantly affects its properties.
- the electrical dielectric strength of the flat conductor ribbon cable is determined not only by the dielectric strength of the polymer, but also by the method used.
- Flat conductor ribbon cables are usually produced by sealing the parallel conductor tracks into the polymer, for example polyethylene terephthalate, using an adhesive.
- the conductor tracks arranged in parallel are laminated with polymer films in such a way that the conductor tracks are located between the polymer films.
- the conductor tracks are vapor-deposited on a polymer film or applied by a galvanic process.
- a second polymer film is layered on the first polymer film obtained in this way, the two polymer films being connected to one another with an adhesive which was previously introduced between the two polymer films.
- thermoplastics disclosed in DE 42 00 311 consist of monomers which contain aromatic or heteroaromatic groups.
- Flat conductor ribbon cables were produced according to the examples only with insulation made of polyether sulfone, polysulfone and polyether ether ketone. These polymers were used in the form of films.
- a granulate is melted in an extruder, the melt is extruded through a nozzle and the melt is then cooled in a water bath or on a casting roll. Two of the foils obtained in this way are then pressed with the conductor tracks to produce flat conductor ribbon cables.
- a complete and uniform covering of the interconnects cannot be ensured in this way, since the formation of cavities cannot be completely ruled out.
- a serious problem of this method is that the heat required for hot pressing in the area of the conductor tracks is dissipated from them, so that in the immediate vicinity of the conductor tracks it is not possible to optimally bind the films to the conductor tracks. Due to capillary forces, media can penetrate the cable and the cables damage the tracks. The flat conductor ribbon cables produced using this method therefore do not pass the so-called capillary test.
- EP 0 938 099 discloses a method for producing flat cables. Parallel conductors with a rectangular cross-section are guided to a crosshead of an extruder and extrusion-coated there with a thermoplastic resin with a bending modulus of 800 to 2400 MPa. Suitable thermoplastic resins are polyamide resins, polyolefin resins and polymers with a sea-island structure. However, this method is not suitable for producing flat conductor ribbon cables, the polymer insulation of which meets high requirements for electrical dielectric strength and dimensional stability.
- the object of the invention is to eliminate the disadvantages of the prior art.
- a method for the production of adhesive-free flat conductor ribbon cables with high dimensional stability and thus high electrical dielectric strength is to be specified.
- a device for the production of such a flat conductor ribbon cable and a flat conductor ribbon cable with high dimensional stability and thus high electrical dielectric strength are to be specified.
- a method for producing flat conductor ribbon cables consisting of several parallel flat conductors, which are embedded in a polymer, is provided that the steps
- step (b) plasticizing the extrudable polymer provided in step (a); (c) setting a constant volume flow of the plasticized polymer obtained in step (b) and
- step (d) the plasticized polymer and the parallel flat conductors are passed together through a nozzle (exit nozzle) of the tool, as a result of which the parallel flat conductors are completely embedded in the plasticized polymer with the formation of an insulating layer which encases the flat conductors.
- the process is a process for the continuous production of flat conductor ribbon cables.
- the invention is therefore based on the knowledge that the production of a constant volume flow, with which the plasticized polymer is fed to the tool, leads to polymeric insulation of the flat conductors, which is considerably more dimensionally stable than in the prior art.
- the higher dimensional stability which is an essential advantage of the method according to the invention, also leads to better properties of the flat conductor ribbon cable, in particular to a better electrical dielectric strength.
- the flat conductor ribbon cables manufactured in this way therefore meet the considerably more stringent requirements in the past two years, which, for example, tomobilindustrie to the flat conductor ribbon cables it uses.
- the flat conductors used should have a rectangular cross-section.
- the flat conductors can be metallic conductor tracks, which are formed, for example, from copper.
- the terms “conductor track” and “flat conductor” are used synonymously.
- the provision of the extrudable polymer expediently comprises drying the polymer.
- the drying time can be between 30 min and 4 h and the drying temperature between 50 and 160 ° C.
- any polymer that is extrudable can be used in the process according to the invention. Because of their properties, however, the polymers polyether sulfone, polyether imide, polyethylene naphthalate, polypropylene and derivatives of these polymers or mixtures which contain these polymers and / or derivatives of these polymers are preferred. Polyether sulfone is particularly preferably used as the polymer.
- the constant volume flow of the plasticized polymer can be adjusted with a melt pump. With the help 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 low dimensional stability would be obtained, and in the case of polymers such as polyether sulfone, even an insulation surface with a flaky character (so-called melt fracture). The electrical dielectric strength of these flat conductor ribbon cables is accordingly low.
- the volume flow is constant, whereby the exact parameters depend on the melt pump used. In this context, “constant” means that the volume of the continuous volume flow that is fed to the tool varies by at most + 2.5% per unit of time.
- the output of the extruder can be regulated by means of 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 include adjusting the position of the conductor tracks in the polymer.
- the conductor tracks are preferably 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 passing the ribbon cable through a tempered water bath and / or a cooling medium. According to the invention, a device for producing flat conductor ribbon cables is also provided
- This device is particularly suitable for carrying out the method according to the invention.
- the device for providing an extrudable polymer expediently comprises a dryer for drying the extrudable polymer.
- the tool for bringing together the constant volume flow of the plasticized polymer with the parallel flat conductors expediently consists of
- the wire guide preferably guides the parallel flat conductors vertically through the tool.
- the vertical routing of the flat conductors offers the particular advantage that influences of gravity on the insulating material are avoided, which, with horizontal guiding, as described in the state of the art, leads to different thicknesses of the insulation on the top and bottom of the flat conductor ribbon cable leads.
- the device expediently comprises a device for cooling the flat conductor ribbon cable obtained in the tool.
- This device can be a tempered water bath and / or a cooling medium.
- Show 1 shows a top view of an embodiment of the device according to the invention for producing a flat conductor ribbon cable
- FIG. 1 is an illustration of the side view of the embodiment shown in FIG. 1,
- FIGS. 1 and 2 are a longitudinal sectional views of a tool of the embodiment shown in FIGS. 1 and 2 with wire guide, deflection and outlet nozzle,
- FIG. 4 is a cross-sectional view of the tool shown in FIG. 3;
- Fig. 7 is a sectional view of a ribbon cable
- FIG. 8 shows a representation of measured values which have arisen from the evaluation of micrographs of a flat conductor ribbon cable produced according to the invention.
- the device for the continuous production of flat conductor ribbon cables with high dimensional accuracy has an extruder 5 in which the extrudable polymer is plasticized.
- the plastifi- graced polymer is fed with a volume flow via a screen changer 7 to a melt pump 8.
- impurities are removed from the plasticized polymer.
- the melt pump 8 With the melt pump 8, a constant volume flow is produced from the pulsating volume flow of the plasticized polymer which leaves the extruder 5.
- This constant volume flow of the plasticized polymer meets in the tool 9 with the conductor tracks 2, which run parallel to one another and pass through the tool 9 vertically (FIG. 2).
- the vertical running direction of the flat conductor is achieved by means of a deflection roller 8, which is arranged above the tool 9.
- the conductor tracks 2 are guided continuously in the wire guide 11 by the tool 9 (FIG. 3).
- the plasticized polymer enters the tool 9 via the material inlet 15 (FIG. 4). From there, the plasticized polymer is guided into the polymer guide 16 via a material deflection 14 (so-called deflection device) and meets the conductor tracks there, as is shown in section A of FIG. 3.
- the conductor tracks coated with the polymer then leave the tool 9 via the outlet nozzle 12 (FIG. 2, FIG. 4) and are guided through a water bath 10.
- the wire guide 11 is arranged in a carrier element 17 (FIGS. 3 and 4).
- the wire guide 11 has a separate, vertical guide channel 111 for each flat conductor with an inlet opening 112 and an outlet opening 113 on.
- 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 spacing from one another, is determined by the arrangement of the flat conductors 2 provided in the flat conductor ribbon cable 1 to be produced.
- the tool 9 and consequently the wire guide 11 are continuously run through by the flat conductors 2.
- the wire guide 11 In the outer surface of the wire guide 11 there is preferably a horizontal cutout 114 which runs around the entire wire guide. Together with the carrier element 17, this recess 114 forms the material deflection 14. The recess 114 completely surrounds the wire feed 11. The recess 114 is closed at the top, while at the bottom a gap 115 is formed between the support element 17 and the wire guide 11. Gap 115, like the cutout 114, can completely encircle the wire feed 11, but this is not necessary.
- the carrier element 17 has a channel-like feed 171 for the plasticized polymer, which forms the material inlet 15.
- the material inlet 15 is arranged at the level of the recess 114 of the carrier element 17, so that the plasticized polymer reaches the material deflection 14 via the material inlet 15. From there, the plasticized polymer is pressed into the gap 115.
- the outlet nozzle 12 is arranged at the lower end of the wire guide 11.
- the outlet nozzle 12 has a nozzle gap 121 which is opposite the outlet opening 113 of the wire guide tion 11 is arranged.
- a gap 122 is provided between the outlet nozzle 12 and the lower end of the wire guide 11.
- Gap 122 communicates with gap 115 via polymer guide 16. The plasticized polymer thus passes through gap 115 and polymer guide 16 into gap 122
- Polymer guide 16 is formed below the recess 114 between the outer surface of the wire guide 11 on the one hand and the support element 17 and the outlet nozzle 12 on the other hand and completely surrounds the wire guide 11.
- the outer surface of the lower part of the wire guide 11 is expediently designed such that it tapers in the direction of the outlet openings 113.
- the lower part of the wire guide 11 is preferably shaped as a truncated cone with a rectangular base area, the outlet openings 113 being arranged in the rectangular truncated pyramid area with the smaller area.
- the spaced-apart outlet openings 114 are arranged on a line which runs parallel to the longer parallel side edges of the rectangular truncated pyramid surface with the smaller surface area.
- the plasticized polymer can be transported in a directed manner to the nozzle gap 121 of the outlet nozzle 12.
- the plasticized polymer meets the flat conductors 2, which emerge from the outlet opening 113 of the wire guide 11.
- the plasticized polymer is pressed out of the nozzle gap 121, whereby it encases the flat conductor 2 and forms an insulating layer 3.
- the cross section of the nozzle gap 121 is shown in FIG. 5 in the event that three individual flat conductors 2 are continuously guided through the tool 9.
- the nozzle gap 121 has a cross-sectional enlargement 123 for each flat conductor 2. Through this cross-sectional enlargement 123, the respective flat conductor 2 is guided in the center. Because the flat conductors 2 are guided centrally through the cross-sectional enlargements 123, the flat conductors 2 are completely covered with the polymer in the nozzle gap 121.
- the cross-sectional constrictions 124 formed between two adjacent cross-sectional enlargements 123 form the later tapering 4 of the insulating layer 3 (shown in FIG. 7 for a flat conductor ribbon cable with five parallel flat conductors).
- the wire guide 11 can be formed in two parts. 6 shows a first sub-element 116 of the wire guide 11. The second sub-element (not shown) is mirror-symmetrical to the first sub-element.
- a flat conductor ribbon cable 1 obtained with the aid of the method according to the invention is shown schematically and greatly enlarged in cross section in FIG. 7.
- the ribbon cable 1 has conductor tracks 2 which are embedded in an insulating layer 3.
- the height of the cable 1 tapers between the conductor tracks 2.
- the width and height of the conductor tracks 2, their spacing from one another, the thickness of the polymeric insulation layer 3 on the conductor tracks 2 and between the conductor tracks 2 can be changed depending on the intended use of the flat conductor ribbon cable.
- micrographs of the cross section of the flat conductor ribbon cable were made.
- the micrographs were measured using an optical measuring device (DE MEET 220, NL).
- the dimensional accuracy of the polymeric covering was rated as very good if the measured dimensions were within the ranges shown in FIG. 8.
- test specimen with a length of 700 mm was produced from the flat conductor ribbon cables produced in Examples 1 to 4. 10 mm were stripped at each end of the test specimen.
- the test specimen was immersed in a 5% NaCl solution in such a way that the stripped ends of the test specimen protruded from the NaCl solution.
- a voltage of 1.5 kV alternating current, 50 Hz, was applied between all conductor tracks and the NaCl solution, it being ensured that no voltage flashover could occur over the air.
- the samples then had to withstand the applied voltage for 1 minute. After this time, the voltage was increased until the breakdown.
- the test was carried out for three test specimens each.
- test specimen with a length of 700 mm was produced from the flat conductor ribbon cables produced in Examples 1 to 4. 10 mm were stripped at each end of the test specimen.
- test specimen was clamped in a device for testing the flexural fatigue strength.
- the stress test was then carried out under the following conditions:
- test specimen with a length of 50 mm was produced from the flat conductor ribbon cables produced in Examples 1 to 4.
- test specimen was placed vertically in a test medium (70% water, 30% ethanol and dye). The immersion depth was 10 mm. After a dwell time of 5 minutes, the test specimen was removed and the ascent height of the medium was measured using an optical measuring device. The test piece was rated "passed” if no test medium had penetrated the test piece.
- Example 1 describes a method according to the invention for producing an extruded three-core flat conductor ribbon cable.
- Granulated polyether sulfone BASF, DE
