Definitions
- the present invention relates to the field of microwave technology. It relates to a microwave cable according to the preamble of claim 1. It further relates to a method for producing and the use of such a microwave cable.
- a telephone cable which in addition to a plurality of inner conductors has two mutually insulated outer conductor, which are constructed as bandings of a metal foil.
- the outer conductors are used for separate transmission of signals.
- US Pat. No. 2,447,168 discloses a high-frequency cable in which two inner conductors are enclosed by a dielectric and two bandings made of metallized paper are applied to one another on the dielectric.
- US Pat. No. 6,201,190 shows a coaxial cable in which the dielectric surrounding the inner conductor is enclosed by two film strips lying one above the other.
- the film strips are designed as aluminum-polyester-aluminum laminates.
- the insertion loss becomes unstable during bending or twisting as the windings of the tape shift or loosen, and a cable attached to the cable end can not be adapted to such a condition because the tape can be detached after stripping the cable end, and therefore no longer fits tightly.
- the microwave cable according to the invention which is provided for a frequency range from 0 Hz to at least some 10 Hz, comprises a central inner conductor, a dielectric concentrically surrounding the inner conductor, an outer conductor concentrically surrounding the dielectric, and a microwave conductor concentrically surrounding the outer microwave cable Sheathing.
- the outer conductor comprises two superposed, electrically conductive banding, that the bandages are each wound in an overlapping manner, and that the bandages are wound progressively in opposite directions.
- the bandings are wound in opposite directions of rotation.
- a concentric wire mesh is disposed between the outer conductor and the sheath.
- a further embodiment of the invention is characterized in that the bandings are each constructed from a metal band.
- the metal bands have the same width and the same thickness.
- an embodiment of the inven tion is advantageous in which the microwave cable has an outside diameter of a few millimeters , in particular about 1, 5 mm, the metal strips each have a width of a few millimeters, in particular about 1, 5 mm, and the thickness of the metal strips each a few 1/1 00 mm, in particular about 0.035 mm.
- Another embodiment of the invention is characterized dad urch that the Metallbän consist of the same material.
- the metal strips are made of copper and are silvered on the surface.
- the metal strips are each wound with an overlap of about 45% and with an offset per revolution of about 0.8 mm.
- the sheathing is made of FEP.
- the method according to the invention for producing a microwave cable according to the invention comprises the following steps:
- An embodiment of the method according to the invention is characterized in that the first banding is applied with a first direction of rotation and that the second banding is applied with a second direction of rotation opposite to the first direction of rotation.
- the microwave cable is used in a connection cable which has a coaxial connector at the ends, wherein its outer conductor is electrically conductively connected to the exposed outer conductor of the microwave cable.
- the outer conductors of the coaxial connectors are each soldered to the outer conductor of the microwave cable.
- FIG. 1 shows the cross section through a M ikrowellen cable according to an embodiment of the invention.
- FIG. 2 shows a connection cable with a microwave cable according to the invention and coaxial connectors attached to the cable ends;
- FIG. 3A-C show various steps in the production of a microwave cable according to an embodiment of the invention
- FIG. 4 shows in a section the parameters which determine banding in the microwave cable according to the invention
- FIG 5 shows the stabilizing effect of the bandages according to the invention during assembly or cutting to length of the microwave cable at both ends.
- Fig. 1 shows the cross section through a microwave cable 1 0 according to an embodiment of the invention.
- a central inner conductor 1 1 is arranged, which may for example consist of a silvered copper wire.
- the inner conductor 1 1 is concentrically surrounded by a dielectric 1 2, for which the usual materials in the H F-technique, for. As PTFE, come into question.
- the dielectric 1 2 is in the radial direction successively concentrically surrounded by a first banding 1 3 and a second banding 1 4, which will be discussed in more detail.
- a concentric wire mesh 1 5 which is constructed for example of silver-plated copper wire.
- This concentric layer arrangement is finally surrounded on the outside by a protective U mmantelung 1 6, which preferably consists of a FEP (Fluorinated Ethylene Propylene).
- FEP Fluorinated Ethylene Propylene
- the bandings 1 3, 1 4 are each composed of a metal strip 2 1, 22 (see FIG. 3).
- the two metal bands 2 1, 22 may be formed fundamentally different in material, thickness and width. However, they preferably have the same width B (see Fig. 4) and the same thickness.
- the metal bands 2 1, 22 also consist of the same material, preferably of copper, which is silvered on the surface.
- the microwave cable 1 0 can have an outside diameter D (see Fig. 2) of a few millimeters, in particular about 1.5 mm.
- the metal strips 21, 22 for the banding 13 and 14 then preferably each have a width B of a few millimeters, in particular about 1, 5 mm.
- the thickness of the metal strips 21, 22 is then each a few 1/100 mm, in particular about 0.035 mm.
- the metal strips 21, 22 in the banding 13 and 14 according to Figure 4 each with an overlap of about 45% (overlap area 23) and with one offset per revolution (step size w) of about 0, 8 mm wound.
- the decisive difference lies in the fact that the overlapping wound stripings 13 and 14 are wound progressively in opposite directions with respect to the cable, as clearly shown in FIG.
- an output arrangement is first provided from the inner conductor 11 surrounded by the dielectric 12 (FIG. 3A), which may have a predetermined length L, which can be, for example, several kilometers, between a first cable end 19 and a second cable end 20 extends;
- the lower first banding 13 is applied to this output arrangement 11, 12 by overlapping the output arrangement 11, 12 with a first metal band 21, beginning at the first cable end 19 and progressively (see directional arrow) to the second cable end 20.
- the sense of rotation when wrapping is in the illustrated example in the direction of arrow counterclockwise.
- the second bandage 14 is applied by overlapping the initial bandage 13, which is provided with the first bandage 13, with a second metal band 21, beginning at the second cable end 20 and advancing (FIG. see direction arrow) to the first cable end 19.
- the direction of rotation when wrapping is seen in the example shown in the arrow direction in clockwise direction.
- microwave cable 10 can be completed by applying further layers (wire mesh 15, sheath 16).
- the metal bands 21, 22 are preferably made of the same material (silvered Cu film), have the same width B and have the same thickness. With an outer diameter D of the microwave cable of a few millimeters, in particular approximately 1.5 mm, the metal strips 21, 22 preferably each have a width B of a few millimeters, in particular approximately 1.5 mm. Their thickness is preferably in each case a few 1/100 mm, in particular about 0.035 mm.
- the microwave cable 10 can be assembled or cut to length at both ends on the basis of the specially wound bandings 1 3 and 1 4 and provided with a connector, without unintentional deterioration of the internal banding 1 3 determining the electrical properties Properties occurs.
- the cable outer conductor consists of two overlapping metal bands, which are not only wound in opposite directions, but are also reversed in the winding direction compared to the prior art.
- the winding of the second banding begins at the cable end of the first band (wound forward / backward).
- the oppositely wound banding (double band) with opposite winding direction bring advantages in the assembly: at both ends of the cable is always a winding self-fixing due to Ü overlapping. In the same winding direction or single band, however, only one end of the cable would be self-fixing. Without this self-fixing, the tape is cut when the cable is cut to length, so the diameter becomes larger. A connector assembly is then possible only under the condition that the cable entry of the connector has a sufficiently large diameter. However, then the centering of the cable in the connector over the tape is no longer given, which can lead to impedance deviations and thus H F reflections. In addition, the larger inner diameter of the absorbed banding is also an electrical H F impurity (impedance deviation), resulting in H F reflections. The relaxed band may also cause insertion loss instabilities. • The double belt also provides much more (mechanical) stability than a polymer skin over the belt.
- the microwave cable can be used for B. in cable assemblies used for test & measurement, especially in the context of multiple coaxial connectors, as described in WO 2009/1 1 1 895 A 1.
- the invention results in an H F coaxial cable with high requirements for stability of the insertion loss, optimum H F adaptation to the connector, economical assembly and very good shielding attenuation.
