Definitions
- the invention relates to a signal cable, namely a coaxial cable or a balanced signal cable having the features of the preamble of claim 1.
- the invention further relates to the use of such a signal cable for high-frequency signal transmission.
- Coaxial cables are often used as signal cables for transmitting high-frequency signals, for example in the GHz range. Due to their special construction with a central inner conductor designed as a signal conductor, with the dielectric as well as with a hollow-cylindrical outer conductor formed by one or more shield layers, the interference-free transmission is also made possible by high-frequency, broadband signals. In the case of external interference fields, these are shielded from the shielding layer and do not affect the signal transmission at the inner conductor.
- symmetrical signal cable are used for signal transmission. These consist of at least one pair of stranded, insulated signal conductors that form a stranded composite. This is surrounded by a shield (Paartubung).
- the two signal conductors of the pair are driven symmetrically with the signal to be transmitted, in which one signal conductor the original signal and in the other signal conductor an inverted (phase-shifted by 180 °) signal is fed.
- the level difference between the two signal conductors is evaluated. In the case of an external noise level, this likewise affects the two signal levels in the signal conductors, so that the difference signal remains unaffected.
- Typical such data cables have, for example, four or more
- CONFIRMATION COPY jointly managed pairs of wires.
- Such cables are used, for example, in computer networks as Cat 5 or Cat 6 cables.
- the so-called crosstalk is known as a disturbing effect, in which the signal transmission in the one pair of wires affects the signal transmission in the other pair of wires.
- US Pat. No. 6,318,062 B1 discloses a stranding machine with which a variation of the lay length of a wire pair can be made.
- the present invention seeks to provide a signal cable, namely a coaxial cable or a balanced cable with improved properties, especially in the transmission of high-frequency data signals.
- the signal cable is designed and intended as a high-frequency signal cable for transmitting signals with a frequency in the gigahertz range, in particular up to about 100 gigahertz.
- the signal cable is designed either as a coaxial cable or as a balanced signal cable.
- the coaxial cable generally has a signal conductor designed as an inner conductor, which is surrounded by a dielectric and then by an outer conductor, which is usually formed as a braided shield, which in turn is surrounded by a cable sheath.
- the symmetrical signal cable has at least one stranded pair of wires, which is formed from two insulated signal conductors and which is surrounded by a shield.
- the shield surrounds exactly one pair of wires, each pair of wires of the cable is therefore surrounded directly by a Paartransportung.
- the so-called quad-stranding in the case of a symmetrical signal cable is known, in which two pairs of wires forming a signal pair are stranded together.
- This four-stranded composite is also directly surrounded by a shield.
- the four individual signal conductors are in a square arranged, wherein the diagonally opposite signal conductors each form a signal pair for transmitting a respective data signal.
- the signal conductor is formed as a stranded conductor consisting of a number of individual stranded wires and the stranded wires are stranded together under a varying lay length.
- the signal conductors are stranded together at a varying pitch length in a symmetrical signal cable.
- This embodiment is based on the knowledge that even the strictly homogeneous constructed signal cables, as they are already used today for the transmission of signals, for example up to 100 megahertz, for higher-frequency signals, for example greater than 500 megahertz, and especially in the single-digit gigahertz range only still conditionally suitable. Investigations have shown that, despite an exactly homogeneous design of the coaxial cable without form errors, as described for example in DE 19 43 229, a return loss occurs at defined frequencies.
- these disturbances are caused by the basic stranding periodicity of the stranded components, that is, either the stranded individual stranded wires of the signal conductor designed as a stranded conductor or by the signal conductors stranded together in a symmetrical cable.
- the varying lay length is selected, whereby the return loss occurring at a defined frequency range is reduced or distributed over a larger frequency band.
- This embodiment with the varying lay length is thus based on the knowledge that periodic structures are introduced directly due to the stranding or Verlitzreaes, despite the homogeneous, trouble-free design of the signal cable without form error in a surprising manner for a high-frequency data transmission, a periodically recurring, regular disturbance represents.
- These disturbances lead to an increase in the return loss, ie at least one frequency-fixed signal component is increasingly reflected and fed to thrown back and thus reduces the transmitted signal power.
- Return loss is generally understood to mean the ratio of transmitted to reflected power or of injected energy to backscattered energy. The return loss is therefore a measure of backscatter effects in signal propagation in the signal cable. The backscatter effects occur at impurities in the transmission path.
- the periodic structure introduced by the lay length therefore leads selectively within the signal to a high, peak-like return loss at a defined frequency (wavelength). Due to the varying lay length, this peak is reduced at a defined frequency, so that overall the return loss is reduced at this critical frequency. Due to the variation of the lay length, the return loss as a whole is distributed over a wider frequency range as a result of the disturbances introduced by the stranding. This gives the possibility, for the individual frequencies, the maximum allowable return loss even with high frequency data signals.
- lay length of a stranded conductor is generally understood to mean the length that a single stranded wire requires due to stranding to complete full wrap (360 degrees) in the longitudinal direction about a strand center. Under varying lay length is therefore understood that the length of distance, which requires a respective individual stranded wire for a 360 degree rotation over the length of the stranded conductor changes. Accordingly, the lay length of the stranded composite also means the length which the individual insulated signal conductor requires for complete wrapping.
- stranded conductors are preferably referred to as so-called concentric stranded conductors, in which the individual stranded wires have a precisely defined position, so that a regular structure is ensured.
- one or more layers of individual stranded wires are generally stranded around a strand center.
- the Litzen scholar itself is usually also a Litzendraht.
- the central stranded wire is surrounded by six further stranded wires.
- the stranded conductors can alternatively also be designed as so-called bundle strands. In these multiple individual wires or bundles of wires are ver chandeliergt. In contrast to concentric strands, the individual wires do not assume a precisely defined position within the strand, and there is no fixed order in the position of the individual strands relative to one another.
- symmetric signal cables are meant cables with at least one conductor pair of isolated signal conductors, which are jointly provided for the transmission of a signal by feeding an original signal and an inverted signal thereto.
- the conductor pair forms the stranded compound which is surrounded by the shielding.
- quad stranding in particular the Sternvie- rer known in which each two cores (isolated signal conductor), the star quad, the diagonally opposite signal conductors, the respective pair of conductors.
- the four stranded together in the quad stranding signal conductors form the Verseilverbund, which is surrounded by the shield.
- the signal cable has a plurality of stranded connections surrounded by a shield, for example a plurality of shielded pairs or star quads or combinations thereof, which are usually surrounded by a further overall shielding.
- the lay length varies with a predetermined difference value by an average lay length.
- the beat length therefore varies within a bandwidth formed by the difference value about an average value up and down.
- the mean stroke length plus the difference value therefore gives a maximum stroke length and the mean stroke length minus the difference value indicates the minimum stroke length. Intermediate values are taken between the maximum and the minimum lay length.
- the difference value is in the range of 5 to 25 percent and in particular in the range of 10 to 20 percent of the average lay length.
- the resulting stroke length therefore varies between 80 and 90 percent of the mean stroke length as minimum stroke length up to 110 to 120 percent of the mean stroke length as maximum stroke length.
- the lay length oscillates about the average lay length, thus increasing alternately continuously up to a maximum lay length and up to a minimum lay length.
- the change of the lay length is preferably continuous and continuous.
- the increase and decrease follows in particular a, for example, sinusoidal wave motion.
- the variation of the lay length can be particularly easy to realize in terms of manufacturing technology.
- electronically controlled Verlitz- or stranding machines this is done, for example, by a variation of the rotational speed of the so-called Strike when stranding and / or a variation of the take-off speed in the longitudinal direction.
- a varying lay length can be achieved by means of eccentrically mounted wheels within a drive gear.
- the lay length therefore changes in particular arbitrarily, preferably randomly. This is achieved, in particular in the case of electronically controlled stranding machines, preferably by a corresponding uneven activation of the stranding machine.
- the lay length is specified via a random number generator.
- the average lay length is preferably in the range of 1 to 40 mm, in particular in the range of 5 to 40 mm. Conveniently, the average lay length is generally about 3 to 50 times the diameter of the signal conductor. Due to this selected bandwidth of the average lay length in combination with the selected average lay lengths, a stranded conductor with good return loss properties is achieved, even at high frequencies, starting from the current conventional stranded conductors with the usual lay lengths.
- the varying stroke length can be characterized by an envelope, which thus indicates the increase or decrease of the stroke length.
- the envelope itself has a length in the range of a few meters.
- the envelope may have a maximum length of up to 50 meters but preferably has a significantly shorter length, for example, of only 0.3 meters. In principle, therefore, there is the possibility that, following this length or periodicity of the envelope, a respective lay length is repeated, that is to say repeated with a periodicity which corresponds to the periodicity of the envelope.
- the selected length of the envelope in the range of a few meters is achieved that at typical cable lengths for which the signal cables are usually used, at most only a few lay lengths repeat identically. Overall, this effectively avoids a high return loss peak.
- Such signal cables are used, for example, as so-called patch cables in networks. In general, the cable lengths are in the range of a few meters, for example, at a maximum of 30 m and in particular at a maximum of about 15 m.
- the length of the envelope is characterized by the distance between two zero crossings through the average lay length with increasing lay length.
- the length of the envelope in a wave-shaped envelope therefore corresponds to the length of the overall wave, for example a sinusoidal wave.
- the envelope is preferably in each case a symmetrical, for example sinusoidal or serrated wave. This is therefore preferably only stretched. Your maximum and minimum values remain the same.
- the variation of the length of the envelope is comparatively small and is for example only 5 to 10 percent of an average length of the envelope.
- Such a varying adjustment of both the lay lengths and the envelope of the lay lengths can be achieved in a particularly simple manner by means of an electronically controlled stranding machine, in particular the take-off speed. Overall, therefore, such a Verseilverbund process technology comparatively easy to produce.
- the variation of the envelopes can be described by a total envelope.
- This is preferably likewise defined, for example, by a shaft.
- the length of the envelope varies continuously around an average value.
- the length of the total envelope is preferably in the range of several 10 meters and in particular in the range of, for example, 20 to 30 meters. This measure ensures that within the usual cable lengths, for which the present signal cables are used, a repetition of a lay length with the same periodicity is excluded.
- a uniform variation of the lay length is set by the varying envelopes as well as by the total envelope, which is technically easy to handle.
- the resulting envelope in particular the total envelope, preferably has no periodicity.
- the maximum or minimum beat length within two successive envelopes i. the maxima or minima of the envelopes assume different values.
- the slope of successive envelopes varies. It may also be provided that the degree of increase is different from the degree of decrease within one envelope. The increase or decrease of the lay length between two maxima or minima thus varies.
- the stranding concept described here with the varying lay length for avoiding or at least reducing the return loss is used according to a first embodiment in coaxial conductors, which have a stranded conductor as a signal conductor.
- a stranded conductor preferably a single-layer stranded conductor is used, in which therefore only one layer of stranded wires are used, which are stranded for example around a central stranded wire.
- the stranding of the stranded conductor takes place in a one-step stranding process, since this is particularly cost-effective.
- the individual layers preferably each have the same direction of impact and lay length.
- the stranded conductor is conveniently prepared in a single-stage stranding process for cost reasons.
- the individual stranded wires therefore generally run parallel to one another and therefore each have the same lay length.
- a stranded conductor is not limited to the application of coaxial cables, but is preferably also used in other high-frequency signal cables with stranded conductors, especially in symmetrical signal cables.
- the stranding concept described here with the varying lay length is used according to the second embodiment in the stranding of symmetrical signal cables.
- Such symmetrical signal cables each have a signal pair or a stamper surrounded by a shield. By shielding a reliable protection against disturbing external effects such as the crosstalk is already ensured.
- Such pairs of wires surrounded by a pair shield are used, for example, in network cables according to Cat 7, Cat 7a and higher.
- the signal conductors with a variable the stroke length stranded as stated above.
- different interference effects namely interference from the outside or interference problems on the one hand and the return loss problem on the other hand are avoided by two different measures, namely the shielding on the one hand and the varying stroke length on the other hand.
- the individual signal conductors of the stranded composite consist of stranded conductors and both the signal conductors and the individual stranded wires are formed with varying lay length. To reduce the return loss therefore a double stranding optimization is provided.
- a symmetrical signal cable in the assembled state, it is connected in each case to a feed device and to an evaluation device, wherein an origin signal to be transmitted is fed via the feed device into one signal conductor and an inverted signal into the other signal conductor.
- the evaluation device is designed to evaluate the level difference between these two signals. This also eliminates additional interfering influences from the outside, since they typically act simultaneously on both signal parts and thus leave the level difference uninfluenced.
- the shielding in both a coaxial cable and a balanced signal cable is usually formed as a shielding braid.
- the braid is generally a longitudinally extending hollow body formed by the regular meshing of a plurality of braid strands.
- the mesh strands themselves consist of a plurality of individual fine strands. Usually, the individual mesh strands are also intertwined under a fixed lay length.
- the braid or the shield is generally designed such that a particularly uniform shielding takes place to the outside or to the inside. Accordingly, the shield is formed homogeneously and has a constant screen attenuation.
- double shielded shields which are typically formed of two shielding layers, wherein the one layer is formed for example from the shielding braid and the other layer of a metal foil.
- the lay length of the individual mesh strands of such a shielding braid varies over the length of the Ablegeflechts.
- an uneven variation is also preferably provided here.
- the design of the shielding braid with varying lay length is also possible and provided irrespective of the configuration of the stranded conductor and / or the stranded composite with varying lay length.
- the signal cable is therefore designed in an expedient embodiment as a high-frequency cable for the transmission of data with a frequency in the gigahertz range, in particular up to about 100 gigahertz.
- FIGS. show in schematic representations:
- FIG. 3 shows a sectional view through a symmetrical signal cable with a paired pair of conductors
- Fig. 4 is a highly simplified representation of a device for data transmission with a balanced signal cable
- FIG. 5 shows a side view of a shielding braid of the coaxial cable
- FIG. 6 shows a uniformly varying course of the lay length
- Fig. 7 is a varying envelope of the lay length
- Fig. 8 shows a greatly unevenly varying course of the lay length 9A is a qualitative representation of the course of the return loss compared to the frequency of a signal in a stranded conductor with a constant lay length and
- Fig. 9B shows the qualitative course of the return loss versus the frequency of a signal in a stranded conductor with variable lay length.
- the coaxial cable 2 a has a central inner and signal conductor designed as a stranded conductor 4 a, which is surrounded concentrically by a dielectric 6 and then by an outer conductor which is formed by a shield 8 formed by a shielding braid. This is in turn surrounded by a cable sheath 9.
- the stranded conductor 4 a has a plurality of individual stranded stranded wires 10 stranded together.
- the individual stranded wires 10 are stranded together so that they each extend along a helix in the longitudinal direction 12 of the stranded conductor 4a.
- a lay length s is defined by the length in the longitudinal direction 12 that a litz wire 10 requires for a full 360 degree turn.
- FIG. 3 different lay lengths s of the stranded conductor 4 a are shown schematically. Emphasized here is a maximum lay length s max and a minimum lay length s min . As can be seen from the side view of FIG. 2, the lay length s changes over the length of the stranded conductor 4a.
- the symmetrical signal cable 2b has a conductor pair consisting of two insulated signal conductors 4b.
- the signal conductors 4a are formed from a line core 14 and an insulation 16 surrounding it.
- the line core 14 is preferably a full conductor designed as a wire, alternatively a stranded conductor optionally with a constant or variable lay length.
- the conductor pair is surrounded by a shield 8 and this in turn by a cable sheath 9.
- the conductor pair forms a stranded composite.
- a so-called auxiliary wire 18 is additionally arranged, which is not absolutely necessary.
- the signal cable 2b consists in the embodiment of the shielded and surrounded by the cable sheath 9 Verseilverbund. In alternative embodiments, several such units are combined to form a total cable and in particular surrounded by a total shield and a total cable sheath.
- the signal conductors 4b of the stranding composite are stranded together with a varying lay length s.
- the situation shown in Fig. 2 therefore applies equally to the stranded composite.
- a signal to be transmitted is fed into the signal cable 2b as shown in FIG. 4 with the aid of a feed device 20 and decoupled and evaluated again with the aid of an evaluation device 22.
- an originating signal D is fed into the one signal conductor 4b and an inverted signal D ', ie phase-shifted by 180 °, is fed into the other signal conductor.
- the evaluation device the level difference between the signal levels of these signals D, D 'is evaluated.
- FIG. 5 schematically shows a side view of the shielding 8 formed by a shielding braid.
- the shield 8 in this case consists of a plurality of intertwined braid strands 24. These are also in turn entangled with one another under a lay length s, as shown schematically in Fig. 3.
- the term impact length s is understood to be the length which a respective braid strand 24 requires in order to perform a complete winding (360 °).
- FIGS. 6 to 8 show different courses of the varying lay length s. These apply equally to the stranding of the stranded conductor 4a, the stranded composite and the Ablegeflechts.
- FIG. 6 first of all a uniform variation of the lay length s is illustrated. This shows on the X-axis the lay length s, which is plotted against the propagation in the x direction and thus in the direction of the longitudinal direction 12.
- the stroke length s oscillates by an average stroke length So, and in each case by a difference value As.
- the stroke length s decreases continuously up to the minimum stroke length s m i n , and then increases again up to the maximum stroke length s max .
- the lay length s therefore oscillates around the mean lay length s 0, in particular uniformly and wavily, as shown by way of example in FIG. 4.
- the frequency of this oscillating variation is preferably not a multiple of the stranding speed.
- stranding speed is understood in particular to be the number of revolutions per unit time of the wire or conductor to be stranded during the stranding process.
- the varying stroke length s is characterized by an envelope E, which is shown in the embodiment in the manner of a sine curve.
- the envelope E preferably increases in a straight line or falls off in a straight line, is therefore formed approximately zigzag-shaped. Due to the uniform variation of the lay length s shown in FIG. 6, the envelope has a fixed periodicity.
- the envelope E itself varies so that identical lay lengths within different envelopes E are not arranged one below the other at the same periodicity.
- the length L of the envelope E preferably varies continuously.
- two envelopes with two different lengths Li, L 2 are shown.
- the variation of the envelope itself also has a period again, so that after a total length L ges again begins the first envelope with the length Li.
- the variation of the individual lengths L, L 2 of the envelope E can in turn be represented by a total envelope not shown here. Their total length corresponds to the illustrated total length L ges - This total length Lges is preferably in the range of 0.3 to 50 meters, whereas the length L of the envelope E is typically in the range of a few meters, for example about 3 meters.
- the variation of the envelope E is in the range of preferably 5 to 10 percent of the length L of the envelope.
- This variation of the lay length s with the variation of the length of the envelope E shown in FIG. 7 is overall technically easy to implement due to the uniform successive variation of the lay length and is therefore preferred.
- non-uniform variation of the lay length s is provided in alternative embodiments, as shown by way of example in FIG. 8.
- the lay length s preferably varies randomly or chaotically.
- the degree of increase or decrease of the lay length s changes over the length x of the signal conductor 2 in the longitudinal direction 12, the degree of increase or decrease of the lay length s. In the illustration according to FIG. 8, this corresponds to the slope of the curve representing the lay length s.
- Per defined length unit of the signal conductor 2 thus varies the increases or decreases of the lay length s, and in particular in each case based on a predetermined defined absolute value of the lay length s. Therefore, the increasing or decreasing areas between two turning points are always compared.
- the intensity of the course of the stroke length s shown that is to say the respective maximum values s max and minimum values s m i n , also varies.
- the envelope of the maximum values shown in dashed lines is therefore not a straight line but a curve which, in particular, does not follow any given function.
- the stranded conductor 4a has a diameter d.
- the average lay length So typically lies in the range of 3 to 50 times the strand diameter d.
- the lay length is in the range of about 1 mm to 40 mm.
- the same characteristic numbers preferably also apply to the stranded composite in the case of the symmetrical signal cable 2b.
- the middle Shock length thus, it is also preferred that approximately in the range of 3 to 50 times the diameter of the respective signal conductor 4b.
- FIG. 8A shows the situation by way of example with a stranded conductor 4a (or stranded composite) with a constant, uniform lay length s.
- the profile of the return loss at a frequency f 0 shows a peak which exceeds an allowable value for the return loss.
- the peak at the critical frequency f 0 is significantly reduced and distributed over a broad frequency band, in the event that the lay length s in the stranded conductor 4a or in the stranded composite is varied. This situation is qualitatively illustrated in Fig. 8B.
- the signal cable 4a, 4b is particularly suitable for high-frequency data transmissions, in particular also in the gigahertz range and preferably up to about 100 gigahertz.
