Definitions
- the present invention relates to a high-speed data cable.
- Typical data transmission cables are more or less rigid coaxial cables, in which an inner conductor is surrounded by a cylindrical outer conductor, and more flexible, differential (symmetrical) cables, in which positive and negative wires are laid parallel to one another.
- the wires can be a solid single conductor or strands of several conductors. The wires are separated from each other by an insulating material. In a strand, the conductors can be loosely next to each other or twisted.
- the differential pair may itself (sheathed) form a cable or form a cable with several other differential pairs in a bundle.
- the WO2009129028 describes a conductor comprising a central element having a length, a plurality of insulated strands disposed about the central element in at least a first and a second concentric layer, and a layer of dielectric material having a propagation velocity around the plurality of isolated strands is arranged around.
- Each of the plurality of insulated strands has a conductive element and a layer of insulating material disposed about the conductive element and a length approximately equal to an inverse of the propagation velocity of the associated dielectric materials multiplied by the product of the length of the central element and the number one hundred.
- the object of the present invention is to provide an improved high-speed data cable, which allows a high-rate (high-frequency) data transmission.
- the core idea of the present invention is to have realized that it is possible to more efficiently enable high-frequency data transmission in a high-speed data cable, resulting in lower attenuation, especially at high frequencies.
- the high-speed data cable comprises at least one pair of wires, with a conductive shield surrounding the wires.
- the conductive shielding results in an increased immunity to interference of the cable, which, inter alia, a faster data transmission is possible.
- An insulating cable sheath encloses the conductive shield and protects the cable from mechanical stress and corrosion, among other things.
- Each of the wires comprises at least three electrical conductors insulated from one another, wherein the conductors are arranged to extend in an equidistant manner to a longitudinal central axis of the respective core.
- the skin effect refers to the narrowing of the signal current in ever smaller space (near or at the conductor surface) at higher frequencies. Effectively, the conductor cross-section available for the current transport decreases or the ohmic resistance increases with increasing frequency. The skin effect thus leads to a high signal attenuation, especially at high frequencies.
- Fig. 1 shows a cross-section of an embodiment of a high-speed data cable 100, hereinafter also referred to as cable 100.
- the cable 100 includes at least one wire pair 102. It is exemplarily designed as a differential (symmetrical) cable in which the two wires 104a, 104b of the wire pair 102 are parallel to one another in an axial direction.
- the two wires 104a, 104b of the wire pair 102 have a differential push-pull impedance and a common mode impedance.
- the transmission of a useful signal takes place in that the difference between the two wires 104a, 104b represents the useful signal.
- a useful signal In contrast, in the case of asymmetrical cables, transmission takes place by means of a useful signal whose value changes with respect to a reference potential (ground).
- the useful signal may have a voltage potential and / or a current strength.
- the useful signal In symmetric signal transmission, the useful signal, especially in the high frequency range, less prone to interference on a transmission link. At high frequencies disturbances interfere more easily, because eg the screen attenuation decreases. Asymmetric cables can not compensate for this.
- the coupling of interference in practice is still reduced by the earth unbalance attenuation. Earth imbalance damping indicates the deviation from the theoretically ideal equality of the positive and negative wires.
- the disturbing influences for example due to capacitive or inductive couplings on the transmission path, are approximately equal in the case of the symmetrical signal transmission on both cores 104a, 104b, so that the disturbance almost disappears during the subtraction of the two signals of the cores 104a, 104b.
- a conductive shield 108 longitudinally surrounds the wires 104a, 104b and forms a Faraday cage around the wires 104a, 104b.
- the wires 104a, 104b may each be surrounded in pairs by a common conductive shield 108. Alternatively, an individual shield per vein or a plurality of veins would be possible together.
- the cores 104a, 104b are protected against external alternating electromagnetic fields by the Faraday cage. That capacitive or inductive couplings of interference to the cable 100 are prevented or at least reduced.
- the Faraday cage of the shield 108 prevents the cores 104a, 104b from transmitting AC electromagnetic fields, thereby further protecting the cores 104a, 104b of the cable 100 and the environment of the cable 100 from electromagnetic emission.
- the conductive shield 108 may be made of any conductive material.
- the conductive shield 108 is metal clad Plastic film or formed from non-insulated metal wires.
- the conductive shield 108 may each at least one wire pair 102 in any form, for example. Wrapped or braided surrounded.
- the conductive shield 108 is a wire mesh in which individual, mutually non-insulated metal wires are overlaid or a plastic-laminated metal foil which is wound around the wires 104a, 104b.
- the conductive shield 108 is fabricated depending on the desired mechanical flexibility and / or the required electrical shielding characteristic of the cable 100.
- the conductive screen 108 may be fabricated as a closed / solid shell or as a combination of the previously described elements.
- the wires 104a, 104b may be twisted together, i. the wires 104a, 104b are twisted in the longitudinal direction about a common axis.
- the twisting of the wires 104a, 104b favors the symmetrical properties of the cable 100. Interferences which act on the wires 104a, 104b from a certain direction, for example, are impressed identically on both wires 104a, 104b of the wire pair 102.
- the individual wire pairs 102 in the cable 100 can be twisted to different degrees with each other. As a result, coupling in of interference of the wire pairs 102 with one another is reduced.
- An insulating sheath 106 encloses the conductive shield 108 and forms the surface of the cable 100.
- the insulating sheath 106 may be made of, for example, polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), or other insulating material.
- the insulating sheathing 106 completely encloses the conductive shield 108 and prevents electrical connection between the conductive shield 108 and the environment of the cable 100.
- the insulating sheath 106 protects the cable 100 from chemical or mechanical influences that may result in damage to the cable 100 , For example, the insulating sheath 106 may be extruded onto the conductive shield 108.
- Fig. 1 shows a first implementation form of a wire 104a, 104b, which comprises three electrical conductors 110.
- the conductors 110 may be made of any electrically conductive material.
- the electrical conductors 110 are made of metal, such as copper or aluminum or copper or aluminum alloys. Copper and aluminum have a low electrical resistivity, which makes them particularly suitable as electrical conductors.
- copper and aluminum have a low electrical resistivity, which makes them particularly suitable as electrical conductors.
- aluminum exhibits a low mass density and thus a low specific weight, whereby the weight of the cable 100 can be kept low.
- the conductors 110 are arranged equidistant (with the same distance) to a longitudinal central axis 118 of the respective wire 104a, 104b.
- a circular arrangement of the conductors 110 around a center of the wires 104a, 104b or the centers of the wires 110 are arranged on a circle around the longitudinal central axis 118.
- the conductors 110 are twisted in each strand 104a, 104b or arranged twisted around the longitudinal center axis 118. Twisting the conductors 110 increases the flexibility of the wires 104a, 104b, i.
- the more twisted the conductors 110 in the wire 104a, 104b the more flexible the wire 104a, 104b can bend, allowing smaller bend radii with the wire 104a, 104b without breaking the wires 110 in the wire 104a, 104b.
- the same electrical (environmental) conditions are achieved for all conductors. However, a stronger twisting leads at the same time to a greater effective conductor length with the same outer length of the cable.
- the individual conductors 110 of a wire are each short-circuited. This can e.g. done by soldering or crimping.
- a plurality of conductors 110 may be arranged equidistantly in the wire 104a, 104b.
- a wire comprises 3 to 18 conductors 110.
- Each conductor 110 adjoins on its outer surface at least one insulating material, in which the conductors 110 of the respective core 104a, 104b run separately from one another.
- the insulating material encloses the conductor 110 and prevents electrical currents between the conductors 110.
- the insulating material between the conductors 110 reduces the influence of the skin effect.
- the skin effect occurs when an electrical conductor with a higher-frequency alternating current flows through it.
- the current density inside the conductor is lower than at the surface.
- the displacement of the current to the surface increases with increasing frequency. This leads to unwanted attenuation of an electrical cable.
- the insulation of the individual conductors against each other increases the effective surface area while maintaining the same cross section. Instead of a single conductor are several small electrical conductors available, creating a larger surface. This leads to an effectively higher conductor cross section at high frequencies. This results in a lower damping in the respective wire 104a, 104b.
- the conductors 110 of the wires 104a, 104b may be adjacent to different insulating materials.
- the conductors 110 are at least partially embedded in insulating material.
- the insulating material forms a wire jacket 116 and may be made of, for example, polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE) or other insulating material.
- the materials may be present as solid or with a gas, eg air, foamed substances.
- the core jacket 116 keeps the wire 104a, 104b mechanically stable.
- the center of the wire 104a, 104b may be recessed from insulating material such that in the center, for example, air as an insulating material adjoins the outer surface of the conductors. Air isolates the conductors 110 from each other and keeps the weight of the wires 104a, 104b low.
- the conductors 110 of the wires 104a, 104b are arranged equidistant from the longitudinal central axis 118 of the wires 104a, 104b.
- all conductors 110 of the wires 104a, 104b have the same overall length.
- the insulating material which surrounds the conductors 110 an exchange of the useful signal between the conductors 110 is not possible.
- conductors can be twisted in multiple layers. This leads in particular to longer cables with insulated individual wires to runtime differences of the useful signal, whereby the maximum signal transmission of the desired signal and thus the maximum transmission rate is restricted.
- all conductors 110 are the same length regardless of the total length of the cable 100, whereby no delay differences of the useful signal in the individual conductor 110 arise.
- Fig. 2 shows a cross-section of a wire 204 of a high-speed data cable according to another embodiment of the present invention.
- wire 204 differs from the wires 104a, 104b in FIG. 1 inter alia, by an insulating coating 212, which encloses each conductor 210 of the wire 204 as an insulating material.
- the insulating coating 212 is designed to completely enclose each conductor 210 laterally, ie on the surface of the longitudinal side.
- the insulating coating 212 allows the conductors 210 and their insulating coating 212 to abut each other without short circuits occurring between the conductors 210. It is thereby a denser arrangement of the conductors 210 in the wire 204 possible, whereby a total of a larger conductor cross-section is ready for the useful signal.
- the adjoining conductors 210 increase the stability of the cable.
- the insulating coating 212 may be, for example, a lacquer layer or a plastic, as used, for example, for the core or the cable sheath.
- the advantage of a resist layer is that a thin-walled and inexpensive insulating coating 212 is possible, wherein the wall thickness of the insulating coating 212 may preferably be in a range of less than 10 ⁇ m to 80 ⁇ m.
- the ratio between the wall thickness of the insulating coating 212 and the radius of the conductor 210 is preferably in the range 0.015 to 0.42. Since the voltage potentials between the conductors 210 of the wires 202 are small, thin-walled insulation is sufficient.
- the Durscherfestmaschine the paint layer insulation is eg in the range of 2kV / mm.
- the potential difference may be 40V. All conductors 210 of a wire 202 carry the same signal, so that, for example due to local differences in transit time, the potential differences remain very small.
- the thin-walled insulation results in a smaller volume and weight of the conductors 210.
- the conductors 210 with the insulating coating 212 are enclosed by the core jacket 216.
- FIG. 2 shown wire 204 of the in FIG. 1 shown cores 104a, 104b by an insulator core 214, which along the longitudinal central axis 118 of the wire 204 is arranged and to which the conductors 210 of the wire 204 can abut.
- the conductors 210 are thus arranged in a circle around the insulator core 214.
- the insulator core 214 holds the conductors 210 and the conductors 210 with the insulated coating 212 at a certain distance from the longitudinal central axis 118 of the core 204, the distance corresponding to the radius of the insulator core 214.
- the conductor centers are at a distance, radius of the insulator core 214 + radius of the conductor 210 with insulating coating 212, away from the longitudinal central axis 118 of the wire 204.
- the insulator core 214 may be made of a more or less flexible material.
- the insulator core 214 in the center of the wire 204 and the insulated coating conductors 210 disposed therealong have the same diameter.
- the insulated coating conductors 210 are adjacent to each other as well as to the insulator core 214.
- Other ratios may be selected between insulative conductor diameter 212 and insulator core 214.
- the diameters of the conductors 210 and the insulator core 214 are selected so that the conductors 210 cover the surface of the insulator core 214 once. That is, the conductors 210 with the insulating coating 212 on the insulator core 214 and against each other. This feature keeps the arrangement mechanically stable.
- the diameter of the insulator core 214 can be selected to be slightly larger, so that when stranded (if necessary) the insulated conductors 210 press into the insulator core 214 and thus forms a closed arrangement of the conductors 210 around the insulator core 214.
- the material of the insulator core 214 is preferably softer than the material of the insulating coating 212.
- the situation may arise that the conductors 210 to one small insulator core 214 are pressed against each other and the insulating coating 212 is damaged.
- the insulator core 214 non-conductive core
- the laminar surface of the insulator core surface (core surface) with conductor 210 with insulated coating 212 ensures that all conductors 210 are the same length, thus eliminating tread differences in the useful signal.
- the insulator core 214 (non-conductor) inside the core 204 (assembly) and the insulating coating 212 also reduces the proximity effect.
- the proximity effect in electrical engineering refers to the effect of current confinement or current displacement between two closely adjacent conductors under the influence of alternating currents due to the stray magnetic flux between them caused by rectified currents in the conductors 210. Similar to the skin effect, the rectified current has in the neighboring ladder the "urge" to prevent the flow of current at the surface. The electricity is forced into a smaller cross section. By keeping the adjacent conductor at a distance, its influence can be reduced.
- the insulator core 214 is preferably made of an insulating material and thus the electrical current is not conductive. Suitable materials for the insulator core 214 are, for example, plastics or rubber. Particularly preferably, the insulator core 214 is made of polypropylene, polyamide or polyethylene. The material may e.g. solid, foamed or processed as a monofilament.
- the weight of the cable is reduced by the replacement of conductors 210 by non-conductors as the insulator core 214.
- the Indian FIG. 2 shown insulating coating 212 and the insulator core 214 are two independent features and can also individually on the in FIG. 1 shown embodiment or be transferred to other embodiments shown.
