Definitions

  • the invention relates to a band cable, its use and a method for its production.
  • ribbon cables are required that not only have the smallest possible dimensions and high long-term flexibility, but also enable the transmission of very high data rates with minimal runtime differences, for example in the range of 2.5 Gbit / s.
  • Such applications are, for example, mobile telephones, PDAs (Personal Digital Assistant) or small computers called laptops and laptops which have parts which can be folded and / or rotated relative to one another and between which a high-speed data transmission is required. Because of the small dimensions, in particular in the case of mobile telephones and PDAs, such data connections are to be effected via ribbon cables with the smallest possible dimensions, also called micro ribbon cables.
  • a particularly reliable data transmission is obtained with the so-called differential signal transmission, in which the data pulses to be transmitted are transmitted over two signal conductors, over one of the two signal conductors in non-negated form and over the other signal conductor in negated form.
  • a certain data bit is thus transmitted on one of the two signal conductors with high potential and at the same time on the other of the two signal conductors with low potential, falling edges occurring on one of the two signal conductors on falling edges on the other of the two signal conductors and vice versa ,
  • This differential signal transmission with opposite pulse shape over the two signal conductors enables a particularly reliable data transmission.
  • the differential signal transmission filters out common mode interference, eg crosstalk, and significantly reduces interference caused by radiation.
  • a cable For high-speed data transmission, a cable is required that has a very high degree of uniformity with regard to its impedance or its wave resistance.
  • adjacent neighborhood is to be understood in the ribbon cable thickness direction and / or in the ribbon cable width direction.
  • electrical parameters such as those required for electrical cables which are supposed to be suitable for high-speed data transmission, are determined essentially by the distance between the two signal conductors. This is especially true for the impedance or the wave resistance.
  • Conventional ribbon cables are single-ply, ie all of their electrical conductors are on the same level. Conventional examples of this are shown in EP 1 271 563 A1, EP 0 961 298 B1 and EP 0 903 757 B1.
  • the electrical conductors are embedded between two insulating tapes corresponding to the width of the ribbon cable, in the case of EP 0 903 757 B1 a shield is additionally provided, formed by two electrically conductive layers which surround the outer sides of the two insulating tapes.
  • a shield is additionally provided, formed by two electrically conductive layers which surround the outer sides of the two insulating tapes.
  • These cables are only suitable for low frequencies and in the case of a shielded version, the flexibility and packing density required for the applications mentioned at the beginning cannot be achieved.
  • the unshielded versions are often unsatisfactory with regard to EMC (electromagnetic compatibility).
  • Alternative solutions such as shielded flexible printed circuit boards and shielded single-layer ribbon cables do not meet the typical mechanical flex life requirements of several hundred thousand flex cycles, as are common in the devices mentioned above with parts that can move with respect to one another.
  • the invention has for its object to provide a ribbon cable that can be produced with the dimensions of a micro cable.
  • a high impedance and transit time accuracy between adjacent signal conductors of a pair of signal conductors should be made possible with such high uniformity that the ribbon cable can be used for high-speed data transmission.
  • the invention provides a ribbon cable which has at least two conductor levels, in each of which a plurality of electrical conductors running in the longitudinal direction of the ribbon is arranged, the electrical conductors in the ribbon cable thickness direction and / or in the ribbon cable width direction by means of a central insulation layer of predetermined thickness acting as a distance insulator are kept at a defined distance from each other and are electrically insulated and positioned against each other and towards the respective ribbon cable outer side by means of an outer insulation layer.
  • the middle insulation layer is located horizontally and / or vertically between two adjacent conductors. In the case of a vertical center insulation layer arrangement, there is a center insulation layer between a pair of conductors located one above the other and an adjacent pair of conductors located one above the other.
  • a material selection is made such that the central insulating layer material has a greater hardness than the outer insulating layer material, in such a way that when an increasing compressive force acting on the ribbon cable direction is exerted on the ribbon cable, the electrical insulating material is displaced by the electrical conductors 105 much sooner than the central insulating layer material ,
  • the central insulation layer and / or the outer insulation layers of the ribbon cable are formed by ribbon-shaped insulating material. 110
  • the option of producing the ribbon cable by extruding the insulation layers is also possible.
  • all electrical conductors are designed as round conductors. In another embodiment, all conductors are designed as flat conductors. In a further embodiment, some of the conductors are designed as round conductors and the remaining part as flat conductors.
  • the invention provides a ribbon cable in which some of the conductors are designed as narrow conductors and the remaining part as wide flat conductors, two narrow conductors each on the same conductor level form a pair of conductors, and each of these conductor pairs is assigned a wide flat conductor of the other conductor level 150 is, the wide flat conductors each have such a width and position that each of these extends in terms of width across the total width of a respective opposite pair of conductors of the other conductor level.
  • Such a ribbon cable is particularly well suited for differential signal transmission in the high-frequency range.
  • narrow leads are located in one of the two conductor levels.
  • each of the wide flat conductors spans an associated pair of narrow signal conductors on the other conductor level, but does not necessarily tower over them.
  • the distance between the narrow conductors and the wide flat conductors in the direction of the ribbon cable thickness is also determined in this embodiment by the central insulation layer and can therefore be

  • the insulating layers are heated by means of a heated roller arrangement as they pass through the gap between the two rollers to such an extent that they melt and the insulating layers are hot-bonded to one another due to this melting.

Abstract

L'invention concerne un câble plat comportant au moins deux niveaux de conducteurs dotés chacun d'une pluralité de conducteurs électriques (13a à 19b) s'étendant dans le sens longitudinal du câble. Ces conducteurs sont mutuellement espacés par un intervalle défini au moyen d'une couche isolante médiane (21) d'une épaisseur déterminée, dans le sens de l'épaisseur et/ou de la largeur du câble, et ils sont chacun électriquement isolés et placés l'un contre l'autre et relativement à la face externe du câble au moyen de couches isolantes externes (23a, 23b). Les matériaux de la couche isolante médiane (21) et des couches isolantes externes (23a, 23b) sont sélectionnés de telle sorte que celui de la couche isolante médiane est plus dur que celui des couches isolantes externes pour que, lorsqu'une force de pression croissante est exercée sur le câble dans le sens de son épaisseur à partir des conducteurs électriques (13a à 19b), le matériau des couches isolantes externes est comprimé beaucoup plus rapidement que celui de la couche isolante médiane.
