Definitions
- the invention relates to a high-frequency cable according to the Preamble of claim 1.
- 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 from an inner conductor, an insulation, an outer conductor and a jacket.
- the outer conductor which is also called an umbrella works to put together from several layers. From the It is known to practice on a longitudinal, to a closed Pipe shaped metal foil additionally a braid to be applied from individual shield wires. Doing so the shield wires at a regular distance from each other over the Extend the scope of insulation. The wires run on parallel to each other, in two groups that cross each other, and helical around the insulation or the inner conductor. Similar run single braidings or double braidings, so-called false braids.
- shields or outer conductors are conditional through its relatively slow manufacturing process, such as braiding or spiders, expensive to manufacture. Also are so-called optimized braids required to get a good one Shielding effect over a certain, relatively narrow frequency range to achieve.
- the invention is based on the endeavor to use a high-frequency cable to be trained so that it can be produced quickly and easily is.
- the shielding effect is said to be about be effective over a wide frequency range.
- the invention solves this problem, starting from one Cable according to the preamble of claim 1, by the features in the characterizing part of claim 1.
- Advantageous further developments are characterized in claims 2 to 3.
- the Invention is basically in all electrical and optoelectric Cables and wires applicable when on a good shielding effect arrives over a wide frequency range.
- the new HF cable achieves a surprisingly good shielding effect: Remains in a particularly wide frequency range the shielding effect is practically constantly good. Broadband Faults are therefore better shielded. For example, Effects from the ignition system of an internal combustion engine avoided. Interference emissions through signal transmissions minimized (EMC), which e.g. with a radio telephone in one Motor vehicle is particularly cheap. Furthermore, it is further process new arrangement very well, in particular to contact electrically. In particular, when stripping the film is removed and the longitudinal wires are intact available for contacting. The number, distribution and thickness of the individual wires are depending on the requirements in individual cases, also in relation to the film thickness, vote.
- the inner conductor 1 is a single wire made of copper with a Diameter of max. 0.26 mm.
- E-CU F21-V1 is selected according to DIN 40500 T5.
- the insulation 2 is made 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 (shield) consists of axially parallel to the Inner conductor 1 running shield wires 3, about 18 on the Number. Material and single wire diameter correspond to that Inner conductor 1.
- the outer conductor (screen) also includes a conductive parallel to the inner conductor 1 Foil 4.
- Foil 4 consists of an aluminum and PVC layer and is 15 mm wide and 0.05 mm thick.
- the aluminum layer is facing the shield wires 3 and forms a closed Pipe.
- 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 5.0 +/- 0.2 mm.
- the jacket is 5 due to the heat of extrusion firmly connected to the PVC layer of film 4.
- the one described Line serves as an electrical vehicle line, namely as antenna cable for a car radio. It has a temperature resistance (3000 h) from -25 ° C to + 90 ° C. she is easy to connect to the antenna and a connector and has the following electrical characteristics: Capacity: 32 +/- 2 pF / m. Attenuation: greater than 60 dB. Through loss (100MHz): less than 15 dB / 100m.
