Embodiment Construction

[0040] The cable 2 shown in the figures has a conductor core 4 directly surrounded by an inner sheath 6 . A heat-resistant film 8 is arranged, in particular wrapped, around the inner sheath 6 . Around the membrane is arranged an outer sheath 10 composed of fluoropolymer. The outer sheath is overextruded onto the inner sheath 6 wrapped with a film 8 by so-called hot extrusion, in particular hose extrusion.

[0041] The conductor core 4 has a plurality of fittings 12 . The fittings are in particular core wires which are each formed by a central conductor 14 , in particular a litz conductor, and a core insulation 16 surrounding the litz conductor. In the exemplary embodiment, a total of five fittings 12 in the form of cores are provided. The fittings are for example twisted together and form a common layer. A further strand, for example a filler strand 18 , around which the fitting 12 designed as a core wire is twisted, is arranged centrally.

[0042] Due to their circular c...

Abstract

The invention relates to a cable having an outer sheath made from fluoropolymer and a conductor core having several individual elements which are surrounded by an inner sheath which penetrates into anintermediate chamber between the individual elements.

Description

technical field [0001] The invention relates to a cable Background technique [0002] Cables (in particular cables used in the industrial field known as industrial cables and which are exposed to aggressive media or are to be subjected to high temperature loads, for example) usually have an outer sheath made of fluoropolymer as the wire The outer sheath of the cable. [0003] However, in such cables with a fluoropolymer-outer sheath, a reliably sealed connection between the outer sheath and the plug housing is difficult because there is usually no connection between the outer sheath and the plug housing. The connection of the material flow is established by melting. In order to achieve a reliable seal between the outer sheath and the plug housing, a so-called crimp connection is usually used, in which the plug housing is crimped or sprayed onto the outer sheath so that a certain plastic deformation of the outer sheath is achieved. In order to achieve a reliable seal and t...
