Definitions

  • the invention relates to an electrical line, in particular a data line, with a transmission core surrounded by a shield, the transmission core being concentrically surrounded by a cable jacket.
  • a data transmission cable with a shield is from the publication WO 2013/159824 A1 known.
  • a shield also serves to shield from the outside, so that no interference fields escape from the transmission core into the environment.
  • Such shields are also required especially for cables for power transmission, especially for high-voltage cables, for example.
  • the shielding is usually designed as an electrically conductive element which surrounds the line core.
  • a wide range of shield variants are available, such as foil shields, braided shields (C shields) or helical shields (D shields) or combinations thereof.
  • C shields braided shields
  • D shields helical shields
  • the shielding it is necessary that the shielding has a high conductivity and, in a connection area, where the electrical line is connected to an electrical component such as a plug or an electrical device, to a reference potential, for example ground potential is electrically contacted. This is associated with increased effort during assembly.
  • a shield that is not or not optimally contacted with the reference potential only shows a poor shielding effect or even leads to additional interference compared to an unshielded line.
  • unshielded data lines are also known for data lines.
  • twisted wire pairs without shielding are often provided, which are used for symmetrical data transmission (so-called unshielded twisted pair, UTP).
  • unshielded data lines are used especially in low-cost applications, for example in the automotive sector, and in those applications in which there are no excessively high demands on the data transmission quality and in particular speed (frequency of the transmitted data signals).
  • Symmetrical data lines are often used for symmetrical data transmission.
  • a signal is transmitted over a first wire and the inverted signal is transmitted over a second wire, and both signals are evaluated together.
  • Two wires form a respective wire pair for symmetrical data transmission.
  • the invention is based on the object of specifying an electrical line with a shield which can be manufactured inexpensively and at the same time achieves an improved shielding effect compared to the conventional lines.
  • the object is achieved according to the invention by an electrical line with the feature of claim 1.
  • the electrical line has a transmission core which is surrounded by a shield.
  • the transmission core as a whole is concentrically surrounded by a cable jacket.
  • the cable sheath itself is now formed in two layers and has an outer layer made of an electrically insulating plastic and a second layer arranged underneath made of a semiconducting material.
  • This embodiment is basically based on the consideration that interference currents caused by external interference fields are diverted via the shielding in the longitudinal direction of the line.
  • a reliable discharge of the interference currents and, in particular, good contacting of the shield with reference potential, for example with ground potential in the area of a connection (plug or device), is conventionally required.
  • the particular advantage of the measure presented here with the second layer made of a semiconductive material is that instead of such a dissipation of the interference currents, they are at least partially already attenuated within the second layer due to its low conductivity.
  • the energy of the interference currents is therefore at least partially and preferably completely consumed in the second layer. This therefore forms a "swamp" for interference fields, in particular external RF interference fields.
  • the outer, conventional insulating layer serves to isolate it from the environment.
  • the second semiconducting layer therefore improves the overall shielding effectiveness compared to conventional unshielded lines. At the same time is one such a second layer of semiconducting material can be applied inexpensively and in a simple manner.
  • the second layer is applied by extrusion, in particular by hose extrusion, onto the transfer core or also onto a shielding layer surrounding the core.
  • the semiconductive jacket has a wall thickness that is particularly constant around the circumference of the transmission core.
  • the wall thickness is expediently in the range between 0.05 mm to 1.2 mm and in particular in the range from 0.1 mm to 0.3 mm.
  • a wall thickness of 0.2 mm is chosen in the case of an extruded semiconducting jacket, for example.
  • the semiconductive jacket has a particularly tape-wound film and / or a fleece and / or individual wires, in particular applied in the manner of a winding, with correspondingly low conductivity.
  • the wall thickness is typically somewhat below the 0.2 mm specified above.
  • a suitably slotted film in particular a metal-clad plastic film, is used. The low conductivity is set through the slots.
  • the outer layer made of the insulating plastic is preferably also applied by extrusion.
  • the two layers are applied in particular by coextrusion.
  • the cable jacket and the second layer extend continuously over the entire length of the cable.
  • the outer layer is in particular an outer jacket of the electrical line that is not concentrically surrounded by any other jacket.
  • the transmission core is generally an electrical transmission core, which is preferably designed for data transmission or, alternatively, for the transmission of electrical power.
  • semiconducting material is generally understood to mean a material whose conductivity is significantly lower than that of metals, as is the case with conventional shielding layers.
  • the conductivity is at least a factor of 10, preferably at least a factor of 100 or even 1000 up to a factor of 10 6 lower than the conductivity of pure copper (in each case at 20 ° C).
  • the cable jacket has a conductive layer below the second layer, that is to say in the direction of the transmission core, which rests on the second layer in an electrically contacting manner.
  • This refinement is based on the consideration that, especially in the case of higher-frequency interference fields, these can penetrate the cable jacket and also the second layer, that is to say that they are only partially attenuated in the second layer. These components of the interference fields then hit the conductive layer and generate interference currents in it. Due to the skin effect, these run on the outside of the conductive layer and therefore penetrate again into the second layer and are further attenuated there. Overall, the energy introduced via the interference fields is used up as completely as possible in the second layer.
  • This conductive layer is expediently designed as a film that is inexpensive to manufacture and apply. If a conductive layer is used here, this is generally understood to mean a conductivity in the area of metals.
  • the conductive film is typically a conventional shielding film, which is often designed as a metal-clad plastic film, specifically an aluminum-clad plastic film, or as a copper film is.
  • the aluminum layer can be applied to one or both sides of the carrier film.
  • the total thickness of such a film is typically in the range between 20 and 100 ⁇ m, the thickness of the at least one metal layer being at least about 7 m or at least 10 ⁇ m and for example up to 30 or even up to 50 ⁇ m.
  • Such comparatively thin metal layers in the range from 7 to 20 ⁇ m are sufficient for the application aimed at here.
  • An electrical line of this type therefore consists of the transmission core, a foil which may surround it as a conductive layer, the second layer made of semiconducting material and the outer insulating layer.
  • Such a line is used in particular to replace previously unshielded data lines, for example unshielded twisted data lines (UTP lines).
  • unshielded twisted data lines UTP lines.
  • the shielding effect of the second layer of semiconducting material that is extruded on and the associated damping of undesired interference currents result in a considerable improvement in data transmission.
  • the introduced interference energy is preferably used beforehand within the second layer.
  • the particular advantage is additionally achieved that for the desired shielding effect - unlike conventional shields - no contacting of the shielding is required in the connection area.
  • the shielding is not electrically contacted, for example not connected to a ground potential.
  • the shielding is due to the second layer in combination with the layer below conductive layer formed.
  • the components are in particular contact plugs or also directly consumers that are directly connected to the line.
  • These data lines are, in particular, symmetrical data lines with at least one wire pair via which a symmetrical signal is transmitted during operation.
  • this is a twisted pair of wires.
  • quad configurations such as the so-called star quad twisting system, are alternatively used as the transmission core.
  • the cable sheath with the semiconducting second layer is used for conventional, shielded cables, especially for coax cables.
  • the transmission core is at least surrounded by a shielding layer, around which the cable jacket is then applied, in particular extruded.
  • this shield layer is connected in particular via a shield contact in the area of the component and connected to reference potential.
  • Such a shield layer forms in particular an outer conductor of a coax line.
  • the shielding layer is a conventional, also multilayered shielding layer, for example as a braided shield (C shield) as a wire wrapping formed screen (D screen or spiral screen) is formed.
  • C shield braided shield
  • D screen or spiral screen wire wrapping formed screen
  • foil shields or a combination of these types of shields are used for a multilayer structure.
  • the special cable jacket structure with the semiconductive second layer achieves an improved shielding effect due to the attenuation of the interference currents in the second layer.
  • the previously described effect is used that interference currents, due to the higher-frequency fields and the skin effect, spread on the outside of the shield layer and are thereby attenuated by the second layer.
  • the cable shielding is formed exclusively by the cable jacket, namely exclusively the second semiconducting layer or, if necessary, also in interaction with the conductive layer .
  • the (overall) shielding is formed by the second layer of the cable jacket (possibly with the additional conductive layer) in combination with the shield layer.
  • the specific resistance of the semiconducting material is generally preferably greater than 1 ohm * mm 2 / m and preferably greater than 10 ohm * mm 2 / m.
  • the specific resistance is typically higher by at least two powers of ten, for example compared to the specific resistance of copper (based on an ambient temperature of 20 ° C.).
  • the specific resistance is preferably less than 1000 Ohm * mm 2 / m and in particular less than 100 Ohm * mm 2 / m.
  • the specific resistance is thus well below the resistance of typical insulation materials.
  • the specific resistance therefore lies in the range between 10 to 100 ohm * mm 2 / m. This ensures good damping.
  • the semiconducting material is, for example, a conductive plastic, that is to say a plastic with intrinsic conductivity.
  • the low conductivity is formed by an insulating plastic with conductive particles embedded therein.
  • the particles are in particular carbon or soot particles, or else carbon nanoparticles. This includes so-called nanoflakes and nanotubes, etc.
  • the desired conductivity is achieved through the carbon particles.
  • the proportion of the particles is selected in such a way that the above desired conductivity or the desired specific resistance is set.
  • the degree of filling of the particles is, for example, in the range between 8 and 55% by volume and in particular in the range between 10 and 40% by volume, based on the total volume of the second semiconducting layer.
  • no metal particles and / or no magnetic, in particular no ferromagnetic or magnetizable particles are used for the semiconducting material.
  • Such comparatively hard metal particles would lead to tool wear during extrusion. Therefore these particles are not used.
  • the semiconductive second layer is arranged directly around the transmission core formed by the wires. It is designed in particular in the manner of an (extruded) hose.
  • an intermediate jacket is arranged between the transmission core, which has exactly one wire pair or also several wire pairs, and the semiconducting jacket, so that the semiconducting jacket has a (minimum) distance from the wire pair. This is at least about 0.5 mm and in particular is a maximum of 1.5 mm. The distance is understood here to mean the smallest distance to a respective wire.
  • the intermediate jacket itself expediently consists of a particularly solid insulating material such as polypropylene.
  • the intermediate jacket therefore forms a suitable dielectric, which has a positive effect on the transmission of the, in particular, symmetrical signal.
  • the data line is surrounded by a further outer jacket made of an insulating material.
  • This can be a solid coat or a foamed coat.
  • Spacer elements can also be provided so that data lines that are adjacent to one another are kept at a defined distance from one another.
  • Such a data line therefore preferably has a (single) pair of wires overall, the pair of wires being formed by two wires, consisting of a conductor, in particular a stranded conductor made of individual strands stranded together and made of a conductive material, in particular copper, a copper alloy or aluminum, a Aluminum alloy etc.
  • the conductor is surrounded by a core insulation.

  • the two wires are stranded together and surrounded by the intermediate jacket. This typically has a diameter that corresponds to twice the core diameter plus plus the minimum wall thickness of the intermediate jacket of preferably 0.5 mm.
  • the diameter of the intermediate jacket is therefore around 2.4 mm.
  • This is then surrounded by the semiconducting jacket, which has a wall thickness of about 0.2 mm, so that this semiconducting jacket has an outside diameter of preferably about 3 mm.
  • this is also surrounded by an outer jacket, which in turn has a wall thickness of, for example, 0.5 mm to 1.5 mm.
  • the line is a symmetrical data line in which the transmission core is formed by at least one pair of wires for the transmission of a symmetrical data signal.
  • the transmission core is preferably formed by at least one stranded pair or also by several stranded pairs or also a four-strand arrangement, etc.
  • no pair shielding is provided. With this symmetrical data line, no shield contact is preferably made in the connection area to a component.
  • the electrical line can be designed as a supply line for supplying a consumer with electrical power in the range of, for example, at least several 10 W or 100 W or also in the KW range.
