Abstract

The invention relates to a film-insulated flat-strip cable, screened on both sides, having a multiplicity of parallel conductors (1 to 12), lying in a row, which are embedded between two dielectric films (13, 14) onto whose outer sides metal coatings (15, 16) are applied. The metal coatings (15, 16) extend over the dielectric films (13, 14) on at least one side where they make contact with a screening conductor (17) located outside the dielectric films (13, 14), and directed parallel to the conductors (1 to 12). <IMAGE>

Description

Die Erfindung betrifft ein beidseitig-geschirmtes folienisoliertes Flachbandkabel mit einer Mehrzahl paralleler Leiter, die zwischen zwei Isolierstoffolien eingebettet sind, auf deren Außenseiten Metallschichten aufgebracht sind.The invention relates to a double-sided shielded foil-insulated ribbon cable with a plurality of parallel conductors which are embedded between two insulating material films, on the outer sides of which metal layers are applied.

Flachbandkabel dieser Art können in Geräten der Datenverarbeitung zur Signalübertragung verwendet werden. Die Metallschichten wirken dabei als Abschirmfolien für die Abschirmung von Störungen, wenn die zu übertragenden Signale störempfindlich sind.Ribbon cables of this type can be used in data processing devices for signal transmission. The metal layers act as shielding foils for shielding from interference if the signals to be transmitted are sensitive to interference.

Bei den bekannten abgeschirmten Flachbandkabeln ist es schwierig, eine Verbindung mit einer Steckvorrichtung herzustellen. Häufig muß hierzu ein Zwischenstück in gedruckter Leitertechnik vorgesehen werden.In the known shielded ribbon cables, it is difficult to establish a connection with a plug device. Often, an intermediate piece in printed circuit technology must be provided for this.

Der Erfindung liegt die Aufgabe'zugrunde, ein beidseitig-geschirmtes folienisoliertes Flachbandkabel der eingangs genannten Art so auszubilden, daß es direkt mit einer üblichen Steckvorrichtung verbunden und als Meterware bezogen werden kann.The invention is based on the object, a double-sided shielded foil-insulated ribbon cable of the type mentioned in such a way that it can be connected directly to a conventional plug-in device and obtained by the meter.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß die Metallschichten mindestens auf einer Seite über die Isolierstoffolien der Signalleiter hinausragen und dort einen parallel zu den Leitern geführten, außerhalb der Isolierstoffolien liegenden Abschirmleiter berühren. Bei dem erfindungsgemäßen Flachbandkabel ist parallel zu den Signalleitern ein Abschirmleiter geführt und kann daher zusammen mit den Signalleitern in einfacher Weise mit einer handelsüblichen Steckvorrichtung verbunden werden. Ein Zwischenstück ist nicht erforderlich.This object is achieved according to the invention in that the metal layers protrude at least on one side beyond the insulating material foils of the signal conductors and there touch a shielding conductor which runs parallel to the conductors and lies outside the insulating material foils. In the ribbon cable according to the invention, a shielding conductor is routed parallel to the signal conductors and can therefore be connected to the signal conductors in a simple manner using a commercially available plug device. An intermediate piece is not necessary.

Die Erfindung ist nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained below with reference to an embodiment shown in the drawing.

In der Zeichnung ist eine Mehrzahl paralleler Leiter 1 bis 12 dargestellt, die zwischen zwei Isolierstoff-folien 13, 14 eingebettet sind. Auf die Isolierstoff-folien 13, 14 werden auf ihren Außenseiten die Metallschichten 15, 16 als Abschirmfolien aufgebracht, die auf einer Seite über die Isolierstoffolien 13, 14 hinausragen und dort einen parallel zu den Leitern 1 bis 12 geführten, außerhalb der Isolierstoffolien 13, 14 liegenden Abschirmleiter 17 berühren, so daß eine leitende Verbindung entsteht. Die Enden der Leiter 1 bis 12 und des Abschirmleiters 17 können dabei abisoliert und in einfacher Weise mit einer handelsüblichen Steckvorrichtung verbunden werden. Die Metallschichten 15, 16, die z.B.'aus Kupferfolien bestehen können, sind nach außen durch Isolierstoff-folien 18, 19 abgedeckt.In the drawing, a plurality of parallel conductors 1 to 12 are shown, which are embedded between two insulating films 13, 14. The metal layers 15, 16 are applied as shielding foils to the insulating foils 13, 14 on their outer sides, which protrude on one side beyond the insulating foils 13, 14 and there, outside of the insulating foils 13, 14, runs parallel to the conductors 1 to 12 touch the shielding conductor 17, so that a conductive connection is created. The ends of the conductors 1 to 12 and the shielding conductor 17 can be stripped and connected in a simple manner with a commercially available plug device. The metal layers 15, 16, which can be made of copper foils, for example, are covered on the outside by insulating foils 18, 19.

Die Herstellung des dargestellten folienisolierten Flachbandkabels kann in einfacher Weise unter hohem Druck und hoher Temperatur durch Pressen als Meterware erfolgen, wobei sich die einzelnen Schichten miteinander verbinden.The film-insulated ribbon cable shown can be produced in a simple manner under high pressure and high temperature by pressing as yard goods, the individual layers connecting to one another.
