Description

Die Erfindung betrifft ein Kabel zur Übertragung von elektrischen Signalen nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zur Herstellung eines solchen Kabels nach Anspruch 14.The invention relates to a cable for the transmission of electrical signals according to the Preamble of claim 1 and a method for producing such a cable according to claim 14.

Für die Anbringung von Steckverbindern an die Adern von elektrischen Kabeln ist es erforderlich, die Adern freizulegen. Hierbei ist es häufig nicht zu vermeiden, daß bei der Entfernung des Kabelmantels auch die innen liegenden Adern beschädigt werden.It is for attaching connectors to the wires of electrical cables required to expose the veins. It is often unavoidable that the Removal of the cable jacket also damage the internal wires.

Zur Entfernung des Kabelmantels ist es bekannt, ein radial einschneidendes Werkzeug zu verwenden, welches den Kabelmantel sowie eine ggfs. vorgesehene Abschirmvorrichtung des Kabels durchtrennt. Schwierigkeiten können noch dadurch entstehen, daß ein unterhalb des Schirmes befindlicher Innenmantel sich nicht leicht entfernen läßt, da dieser mit den Adern verklebt ist.To remove the cable sheath, it is known to use a radially cutting tool use the cable sheath and any shielding device provided of the cable is cut. Difficulties can arise from the fact that a inner sheath located below the screen cannot be easily removed because this is glued to the wires.

Aus der DE 298 08 657 U1 ist ein elektrisches Signalübertragungskabel bekannt, bei welchem die nebeneinander liegenden Adern von einer Polyesterfolie umgeben sind. Über der Polyesterfolie ist ein Innenmantel aus leicht extrudierbarem Polyvinylchlorid vorgesehen. Ein Schirmgeflecht ist ringförmig um den Innenmantel herumgelegt, welches wiederum von einem Außenmantel umgeben ist.An electrical signal transmission cable is known from DE 298 08 657 U1, at which the adjacent wires are surrounded by a polyester film. There is an inner jacket made of easily extrudable polyvinyl chloride over the polyester film intended.

Dieses bekannte Kabel ist mit einigen schwerwiegenden Nachteilen behaftet. Die Polyesterfolie verhindert, daß der Innenmantel die Zwickel zwischen den Adern ausfüllt. This known cable has some serious disadvantages. The Polyester film prevents the inner sheath from filling the gusset between the wires.

Dadurch kann es u. U. zu einer Veränderung der Lage der Adern zueinander und somit zu einer Veränderung der Übertragungseigenschaften kommen. Darüberhinaus muß diese Trennfolie nach dem Entfernen des Innenmantels zeitaufwendig entfernt werden.As a result, it can U. to a change in the position of the wires to each other and thus change in the transmission properties. In addition, must this release film can be removed time-consuming after removing the inner jacket.

Ein weiterer Nachteil besteht darin, daß als Material für den Innenmantel Polyvinylchlorid verwendet wird, welches bekanntlich aus Gründen der Umwelt nicht unproblematisch ist.Another disadvantage is that polyvinyl chloride is used as the material for the inner jacket is used, which is known to be not without problems for reasons of the environment.

Ein gravierender Nachteil ist jedoch, daß der Schirm durch ein Geflecht gebildet ist. Die Aufbringung eines Geflechtes in der Kabeltechnik ist ein zeitaufwendiger Vorgang, wodurch sich die Herstellung eines Kabels verteuert.A serious disadvantage, however, is that the screen is formed by a braid. The Applying a braid in cable technology is a time-consuming process making the production of a cable more expensive.
