Definitions
- the invention relates to a high-frequency cable according to the preamble of claim l.
- a high frequency or RF cable of this type is e.g. a so-called antenna line for the transmission of corresponding radio and television signals.
- this line consists of an inner conductor, insulation, an outer conductor and a jacket.
- outer conductor which also acts as a screen
- outer conductor which also acts as a screen
- the wires should extend at regular intervals from one another over the circumference of the insulation.
- the wires run parallel to each other, in two groups, which cross each other, and helically around the insulation or the inner conductor.
- the process is similar for single braiding or double braiding, so-called mock braids.
- Such shields or outer conductors are, however, expensive to manufacture due to their relatively slow manufacturing process, such as braiding or spinning. So-called optimized braids are also required in order to achieve a good shielding effect over a certain, relatively narrow frequency range.
- the invention is based on the endeavor to design a high-frequency cable in such a way that it can be produced quickly and easily.
- the shielding effect should be effective over a wide frequency range.
- the invention solves this problem, starting from a cable according to the preamble of claim 1, by the features in the characterizing part of claim l.
- Advantageous further developments are characterized in claims 2 to 3.
- the invention is fundamentally applicable to all electrical and opto-electrical cables and lines when it comes to a good shielding effect over a wide frequency range.
- the new HF cable achieves a surprisingly good shielding effect: the shielding effect remains practically consistently good in a particularly wide frequency range. Broadband interference is thus better shielded. For example, influences from the ignition system of an internal combustion engine are avoided. Interference emissions through signal transmissions are minimized (EMC), which is particularly favorable, for example, in the case of a radio telephone in a motor vehicle.
- EMC Interference emissions through signal transmissions are minimized
- the new arrangement is very easy to process further, in particular to make electrical contact. In particular, when stripping the film, are removed, and the longitudinal wires are available intact for contacting.
- the number, distribution and thickness of the individual wires must be coordinated depending on the requirements in each individual case, including in relation to the film thickness.
- the inner conductor 1 is a single wire made of copper with a diameter of max. 0.26 mm.
- E-CU F21-V1 according to DIN 40500 T5 is selected as the material.
- the insulation 2 consists of cellular polyethylene, with a wall thickness of 1.25 mm (nominal value) and an outer diameter of 2.9 +/- 0.1 mm.
- the outer conductor (screen) consists of wires 3 running approximately parallel to the inner conductor 1, about 18 in number. The material and the individual wire diameter correspond to the inner conductor 1.
- the outer conductor (shield) also comprises a conductive foil 4 that is parallel to the axis of the inner conductor 1.
- the foil 4 consists of an aluminum and PVC layer and is 15 mm wide and 0.05 mm thick. The aluminum layer faces the wires 3 and forms a closed tube.
- a jacket 5 is extruded onto the film 4.
- Polyvinyl chloride (PVC) is selected as the material. The wall thickness is 0.5 mm (nominal value), the outside diameter is 5.0 +/- 0.2 mm.
- the jacket 5 is firmly connected to the PVC layer of the film 4 by the heat of extrusion.
- the line described serves as an electrical vehicle line, specifically as an antenna line for a car radio. It has a temperature resistance (3000 h) from -25 ° C to + 90 ° C. It can be easily connected to the antenna and a connector and has the following electrical characteristics: Capacity: 32 +/- 2 pF / m. Attenuation: greater than 60 dB. Through loss (100 MHz): less than 15 dB / 100m.
