Definitions

  • the invention relates to a flat conductor ribbon cable. It relates in particular to a flat conductor ribbon cable for use in coil spring cassettes, in particular for motor vehicles.
  • a winding spring for motor vehicles is known, the stator and rotor are connected to each other via a flexible circuit board.
  • the flexible printed circuit board consists of a carrier foil, on the front and back side conductor tracks are applied, which are arranged opposite to each other. In this way, the largest possible number of interconnects for power transmission in a small footprint should be provided.
  • the flexible circuit board is produced by double-sided printing of the carrier film with a metal layer and then selective etching. In one embodiment of the flexible printed circuit board, conductor tracks with a larger cross section than on the other side of the carrier film are applied on one side of the carrier film.
  • a ribbon cable is known that has a carrier film which carries on its front and back conductor tracks which are arranged opposite to each other. On the outer sides of the ribbon cable foils are applied to the tracks, which isolate the tracks to the outside and against each other.
  • the printed conductors can be flat conductors or round conductors.
  • US 4,149,026 discloses a multi-conductor cable consisting of two layers of insulating material in which circular conductors are embedded. The layers are interconnected so that the round conductors in the first layer offset from the round conductors in the second layer are arranged. The staggered arrangement of the round conductors should allow a further reduction of the capacitive crosstalk.
  • Another flat cable for telephone applications is off US 4,310,365 known. Described are two levels of flat conductors, which are arranged slightly offset from one another. The two levels of the flat conductors are separated by a central film. The sides of the flat conductors facing away from the central film are each coated with an adhesive layer onto which an outer insulation film is then applied. The central film is not coated on its two surface sides with an adhesive layer. Rather, the outer insulating films are bonded by means of the adhesive layers, which contact the outer surface side of the flat conductor, with the central film. The flat conductors are thus only in contact with an adhesive layer on one of their flat sides. In this way, an exact offset of the leads is required, which is necessary to reduce the crosstalk.
  • US 4,367,585 A discloses a flat cable having flat conductors whose exposed ends undergo a change of direction.
  • WO 01/62551 A1 discloses a flexible circuit board for transmitting power between the stator and the rotor of a coil spring cassette. For this purpose, extensions called reinforcements are required, on which receiving sections are formed. From the Aufhahmeabbalden lead electrical lines to a connector.
  • EP 1 164 661 A2 describes a connection structure for a flat conductor element.
  • the object of the invention is to eliminate the disadvantages of the prior art.
  • a flat conductor ribbon cable is to be specified, which is suitable for use in coil springs and allows improved contact.
  • a flat conductor ribbon cable is provided with a first group of flat conductors parallel to and spaced from each other, a second group of flat conductors parallel to and spaced from each other, and outer sheets of insulating material.
  • the flat conductors of the first and second groups are exposed on at least one end face of the flat conductor ribbon cable.
  • the exposed ends of the flat conductors of the first group are spread apart from the exposed ends of the flat conductors of the second group, whereby an offset between the flat conductors of the first group and the flat conductors of the second group is formed at their exposed ends in the thickness direction of the flat conductor ribbon cable.
  • the course of the exposed ends of the Flat conductor of the second group is not subject to change of direction.
  • the outer foils comprise a first outer foil and a second outer foil.
  • the flat conductors of the first group are arranged between the first outer film and a separating film
  • the flat conductors of the second group are arranged between the second outer film and the separating film.
  • the flat conductor ribbon cable has at least one area where the flat conductors of the first group and the second group are exposed and on which the release film and the second outer film, based on the length direction of the flat conductor ribbon cable, over the first outer film to form a Outstanding offset.
  • the exposed ends of the flat conductors of the first group are spread apart from the exposed ends of the flat conductors of the second group in the thickness direction of the flat conductor ribbon cable.
  • the offset between the exposed ends of the second group lead conductors and the exposed ends of the first group lead conductors should be selected, based on the thickness direction of the ribbon conductor cable, to avoid a short circuit.
  • the offset also depends on the selected voltages, which are transmitted by the flat conductors of the first group and the second group.
  • the course of the exposed ends of the flat conductors of the second group is not subject to any change of direction.
  • a change of direction occurs when the exposed ends of the flat conductor from the plane in which they are between the outer Foils extend, are led out, whereby the offset between the flat conductors of the first group and the flat conductors of the second group is formed at their exposed ends.
  • the leads of the first group extend in a first plane and the leads of the second group, with respect to their longitudinal axes, in a second plane, wherein the first plane of the second plane in the thickness direction ( y) of the flat conductor ribbon cable is spaced. If the exposed ends of the flat conductors of the second group are not subject to a change of direction, they run in the second plane, while the exposed ends of the leads of the first group are led out of the first plane.
  • the first and second planes preferably run parallel to one another.
  • the distance between the first plane and the second plane may be smaller than the extension of the first and second group flat conductors in the thickness direction (y) of the ribbon conductor ribbon cable. There may therefore exist a third plane which lies between the first and second planes and runs parallel to them and runs in the flat conductors of the first and the second group. If a flat conductor of one group is arranged between flat conductors of the other group, the flat conductor should be spaced from the flat conductors of the other group in order to avoid short circuits.
  • the flat conductors of the first group are arranged offset from the flat conductors of the second group in such a way that the flat conductors of the first group and the flat conductors of the second group are not opposite one another. Since the flat conductors of the first group are not covered by the flat conductors of the second group and vice versa, the contact of the flat conductors of a group is not hindered by the flat conductors of the other group.
  • the contacting of the leads of both groups is advantageously carried out by the surface side of the flat conductor ribbon cable, which are the flat conductor of the first group closest, since here the first leads are not glued to the release film.
  • such an offset is not mandatory.
  • the flat conductors of the first group are opposed to the flat conductors of the second group, that the flat conductors of one group are arranged overlapping the flat conductors of the other group, or that a flat conductor of one group is opposed by two or more flat conductors of the other group.
  • two flat conductors of the second group can be opposite to a flat conductor of the first group.
  • the distance between two adjacent flat conductors of the first group can in each case correspond to the spacing between two adjacent flat conductors of the second group.
  • the distance B between adjacent flat conductors of the second group, which are opposite one and the same lead of the first group smaller or larger, preferably smaller, than the distance A between adjacent leads of the second group, the different flat conductors facing the first group.
  • distance A corresponds to the distance between adjacent flat conductors of the first group.
  • the distances A are preferably the same size.
  • the distances B should be the same size.
  • the flat conductors of the first group and the flat conductors of the second group can also lie in a common plane.
  • the flat conductors of the first group, the second group or both groups, with respect to the respective group are equally spaced from each other. It can further be provided that the spacing between adjacent flat conductors of the first group corresponds to the spacing between adjacent flat conductors of the second group.
  • the flat conductors of the first group and the flat conductors of the second group are alternately to each other, based on the width direction of the flat-ribbon cable, arranged. This means that on a flat conductor of a group of flat conductors of the other group follows.
  • the spacing between adjacent flat conductors may be less than 0.5 mm due to the offset between the exposed ends of the second group lead conductors and the exposed ends of the first group lead conductors spread therefrom. It is preferably between 0.1 mm and less than 0.5 mm, more preferably between 0.15 mm and less than 0.5 mm, and even more preferably between 0.2 mm and 0.3 mm. A particularly preferred distance is 0.2 mm.
  • the distance between two adjacent flat conductors refers to the shortest distance between the mutually facing outer edges of the flat conductor.
  • the flat conductor ribbon cable according to the invention can also be referred to as ribbon cable with high density, because a higher conductor density, based on the cross section of the ribbon conductor ribbon cable is achieved. This saves the space required for the cable to be used. Nevertheless, the offset between the exposed ends of the second group lead conductors and the exposed ends of the first group lead leads makes it possible to achieve high withstand voltages. Up to now, at a distance of 0.5 mm, dielectric strengths of only 200 V could be achieved, so that chip strengths of 500 V or more, for example of 1000 V or more, can now be achieved.
  • a separating foil of an insulating material is arranged between the first group of flat conductors and the second group of flat conductors.
  • a first adhesive layer is formed between the release film and the second group of flat conductors, against which the flat conductors of the second group rest with an area side, wherein the flat conductors of the first group bear against the release film with a surface side.
  • the flat conductor ribbon cable according to the invention has such a first adhesive layer, ie an adhesive layer between the flat conductors of the second group and the release film, but not an adhesive layer between the flat conductors of the first group and the release film, this adhesive layer-together with the release film outer films as well as, if present, further adhesive layers which are arranged between the outer foils and the surface sides of the flat conductors facing them - for the necessary stability of the flat conductor ribbon cable.
  • the lack of an adhesive layer between the leads of the first group and the release film facilitates access from one face side of the ribbon cable to the first group leads as well as the second group leads.
  • the lack of this adhesive layer allows the spreading or crimping of exposed ends of the flat conductor of the first group at the end faces of the flat ribbon cable, because the flat conductor of the first group - in contrast to the flat conductors of the second group - are not connected to the release film and therefore can be easily detached from the release film.
  • the term "chipping" is understood to mean in particular the bending away of the exposed ends of the leads of the first group from the exposed ends of the leads of the second group on at least one end face of the ribbon conductor cable, whereby the exposed ends of the leads of the first group of the exposed Ends of the leads of the second group are continued. In this way it is possible to use comparatively simple connectors. The contacting of the conductors of these connectors is simplified.
  • At least one second adhesive layer is formed in each case between the outer films and the surface sides of the flat conductors of the first group and the second group, which faces the outer sides of the flat conductor ribbon cable and, if present, faces away from the separation film.

  • the flat conductors preferably have an approximately rectangular cross-section.
  • the term "approximately rectangular in cross-section" of the flat conductor is intended to denote both flat conductors of rectangular cross-section and flat conductors with a cross-section which deviates from an ideal rectangular cross-section, for example by having rounded corners.
  • the thickness of the flat conductors is preferably 10 or more micrometers, for example 35 micrometers.
  • the flat conductors are preferably spaced from the longitudinal edges of the release film and the outer films. The flat conductors can be exposed on one end face of the flat conductor cable in order to simplify contacting of the flat conductors.
  • the distance between two adjacent flat conductors of a group is preferably determined as a function of the extent of the resistance in the transverse direction to the longitudinal direction of the flat conductors. Furthermore, the fact must be taken into account if the flat conductors of one group should not face the flat conductors of the other group. For example, the extension of the flat conductors of the first group in the width direction of the flat conductor ribbon cable may correspond to the distance between the flat conductors of the second group.
  • the first group of flat conductors should comprise at least two flat conductors, preferably at least three flat conductors.
