Definitions
- the invention relates to a flat conductor cable, a so-called FFC with a longitudinal rectangular Cross section, consisting of two essentially parallel, the long sides of the rectangle corresponding surfaces and two corresponding to the short sides of the rectangle Edges and with at least one flat conductor made of electrically insulating plastic is enveloped.
- FFCs have replaced the usual twisted ones in recent years Round cables more and more, especially in the automotive industry. The reasons are mainly in the better handling of the FFC by machines compared to the Round cables.
- this goal is achieved in that in a two-stage extrusion process in the first step, the conductor tracks are covered by the extrudate and that in one second step applied the shield and, if necessary, extrudate is enveloped.
- the two process steps take place in a single one Extrusion head instead, so that the connection is created in the two steps Layers, especially promoted.
- Both individual wires and a braid of wires can be used as shielding a thin film of electrically conductive material can also be used.
- the braid the mechanical connection of the individual layers is particularly good with the film can, if a coated film is used, on the application of the outer extrudate layer to be dispensed with.
- Fig. 1 shows, purely schematically and in section normal to the longitudinal axis, the structure of a FFC 1 according to the invention:
- Individual flat conductors 2 are encased in an extrudate 3 and are held in position by the one hand and electrically by one another on the other hand and isolated from the environment.
- a large number of individual wires 8 form in in its entirety a screen 4, which is both above and below the area of the FFC 1 is located, in which the conductor tracks 2 are arranged.
- the individual wires 8 are essentially parallel to each other and Networking, especially one, is of course not a network loose networking possible.
- the individual wires 8 lie essentially on the surface of the extrudate 3 and the entirety defined in this way is along the entire circumference with an outer extrudate 5 covered.
- This outer extrudate in turn serves for mechanical cohesion and the electrical insulation of the screen 4 and can be the same or different Material exist, like the extrudate in area 3.
- FIG. 2 A variant of an FFC according to the invention is shown in Fig. 2, with the same parts are provided with the same reference numerals, analog parts as in Fig. 1 are the same Reference numerals and a "'": Again, several conductor tracks are 2 in an extrudate mass 3 held on the top and bottom of the blank thus formed is a screen 4 'in the form of an electrically conductive film, for example one Copper foil or an aluminum foil is applied and is in this position by a outer extrudate layer 5 fixed and protected.
- a screen 4 ' the form of an electrically conductive film, for example one Copper foil or an aluminum foil is applied and is in this position by a outer extrudate layer 5 fixed and protected.
- FIG. 3 Another variant by which the versatility of the invention is explained is in FIG. 3 shown: For reasons of clarity, there is an FFC 1 "with only two conductor tracks 2, which are embedded in an extrudate 3. This unit is now in one electrical conductive extrudate, for example PTFE with carbon and a drain 7 made of electrically conductive Material, for example constructed similarly to one of the conductor tracks 2, is enveloped. Around this extrudate 6 there is a plastic sheathing 5 analogous to the embodiments applied to the embodiments according to FIGS. 2 and 2.
- Plastics with a low specific electrical resistance are state of the art known. There can be a variety of technically commonly used plastics be used as starting material, here are only: ABS, EP, EVA, PA, PBTP, PC, PE, PS, POM, PP, PET, PBT, TPU, modified PPO, PPS, PBI, PVC, SB. In these plastics become conductive substances such as: conductivity black, graphite, iron oxide, Copper or aluminum particles or flakes, metallized glass balls or fibers, Stainless steel fibers, carbon fibers, semiconducting tin or antimony oxide on mica or ceramic needles. Other examples are conductive silicone rubber, PPY, PAC, PANI, PPP, PFU, PPV, PT, etc.
- the invention is not limited to the exemplary embodiments shown, but rather can be modified in various ways. So it is possible instead of the film 4 'with the outer extrudate layer 5 to use a plastic-coated film on one side, wherein the plastic layer points outwards and thus the need for a further extrudate layer avoids.
- a film like the film shown in FIG. 2, can be made in one piece envelop the entire inner structure previously formed to avoid any problems with the Avoid capacity of the two separate shielding surfaces 4 '.
- a conductive connection is highly recommended, for example by turning it over and compressing the two foils in their edge area, possibly connected with the addition of heat.
- extrusion heads are of course complex for the extrudates shown, However, it is entirely manageable for the expert on the extrusion structure. It is of course, it is also possible to carry out the two extrusions spatially at a separate location, which on the one hand has the advantage that each of the two spray heads is simpler than a common one, but has the disadvantage that also no matter how close the surface of the extrudate 3 with at least one is covered by a monomolarular air film, which affects the cohesion of the layers becomes.
- the advantage here is, however, the easier possibility of the individual wires 8 or the film 4 'around all four sides, thus also forming the narrow sides and for the favorable electrical connections between the individual parts of the To worry about.
- FIG. 4 An example of the shield application when the shield consists of single wires is in Fig. 4 shows:
- the shielding wires 8 are parallel to the flat conductors 2 via a so-called special wire guide 10 passed through the head.
- the easy-flowing mass 11 is guided over a quill 12 and the head housing 13 and penetrates between the individual Wires 8 through and also penetrates between the conductor 2.
- the outer shape gets the shielded conductor 1 from the nozzle 14.
- the shield 4 'of flat conductors 5 shows:
- the shielding conductors 4 are connected via an outer sleeve 12, which has the necessary recesses, and a so-called special wire guide 10 led.
- the middle insulation layer is introduced via the inner sleeve 15 and further over the special wire guide 10 between the flat conductor 2 and the screen 4 ' guided, the external shaping is carried out as explained above.
- a conductive polymer If a conductive polymer is used, it can be fed through an outer sleeve a special wire guide guides the flat conductors and brings the mass flows of the conductive polymer (inside) and the insulating polymer (outside) together.
- the outer quill similar to that of FIG. 5, naturally has none in this case Openings for the shield conductors.
- the invention is not restricted to the exemplary embodiments shown and described, but can be modified in various ways. So in the embodiment 3 no drain may be provided if the conductivity of the conductive Extrudates are sufficient, the shapes and the number of flat conductors can be different than shown be, combinations of the variants shown can be created and the like more.
