Definitions

  • the present invention relates to a cable, in particular an audio cable, according to the preamble of claim 1 and an audio cable arrangement according to the preamble of claim 8.
  • the present invention is based on the object, a cable, in particular specify an audio cable, and an audio cable arrangement that is simple, cost-effective structure, especially for the transmission of audio signals or for connecting speakers are suitable
  • an intermediate layer is provided between a conductor and an electrical insulation, which is made of hollow filaments or tubing and / or apertures and / or contains such a proportion of air, that the desired low capacitance, in particular a dielectric constant ⁇ r of the entire cable of less than 2.0 is achievable.
  • the intermediate layer is formed as a braid of tubes or Schlaumaterial. This results in a simple and inexpensive construction with significantly improved transmission properties over the prior art.
  • An audio cable arrangement according to the invention is characterized in particular by this from that a sheath is provided, in which the cables in two at least one spacer separated groups are performed.
  • the cladding is elastic and reticulated in which as pipes or hoses trained spacers are used. This leads to a simple construction with very good transmission properties.
  • Another The advantage is that a modular design is made possible, ie individual Cable and spacers used as needed and by the preferred elastic sheath are held together. So becomes a universal Usability and adaptability to the particular circumstances allows.
  • the cable 1 shown in Fig. 1 is in particular a Audio cable, preferably for connection not shown speakers or dg1.
  • the cable 1 can basically also be used for other purposes become.
  • the cable 1 has a conductor 2, which is preferably designed as a stranded wire is and consists at least essentially of copper
  • the cable 1 further has an associated insulation 3, in particular is made of a suitable plastic and preferably by extrusion is made.
  • the intermediate layer 4 has Openings 5 and is made of hollow filaments or tubing. 6 produced.
  • the intermediate layer 4 is formed as a braid.
  • the intermediate layer 4 serves a certain distance from particular Ensure at least 1 to 3 mm between the conductor 2 and the insulation 3. In this case, the intermediate layer 4 supports the insulation 3 at least in substantially uniformly and extends along the insulation 3,
  • the openings 5 are preferably diamond-shaped in the illustrated example formed and in particular have a size in the range of 1 to 5 mm, preferably 2 to 4 mm.
  • the optical coverage of the conductor 2 through the intermediate layer 4 is at Representation example less than 50%, preferably less than 40%, in particular less than 30%, and more preferably is substantially 25% or less.
  • the intermediate layer 4 is preferably made of a material with a dielectric constant ⁇ r smaller than 2.5 and is preferably made of plastic, in particular Pernuoralkoxy polymer (PFA) or polyethylene.
  • PFA Pernuoralkoxy polymer
  • Hose material 6 is particularly thin-walled, hollow and / or flexible. In the illustrated example, it has a diameter of 0.5 to 3 mm, preferably less than 2 mm, in particular less than 1.5 mm and very particularly preferably of substantially 1.1 mm or less
  • the insulation 3 is directly extruded on the intermediate layer 4 or in otherwise suitably applied. It is preferably continuous, especially coat-like, formed and consists of a suitable Plastic.
  • the cable 1 is not shielded.
  • a shield not shown, may be provided, possibly with a second intermediate layer between the insulation 3 and then externally applied, not shown shield.
  • the proposed cable 1 is due to the flexible intermediate layer 4th overall very flexible and therefore easy to lay and easy to handle.
  • Fig. 2 shows a schematic representation of a proposed audio cable arrangement 7, the multiple cables 1 in a common enclosure. 8 having.
  • the envelope 8 is formed like a net in the representation example. she can However, for example, also hose-like or in any other suitable manner be educated.
  • the envelope 8 is preferably flexible and / or elastic. She For example, Teflon or other suitable material.
  • the audio cable assembly 7 further comprises at least one, preferably also in the enclosure 8 arranged spacers 9 to the cables 1 in at least two separate groups 10 to lead.
  • spacers 9 to the cables 1 in at least two separate groups 10 to lead.
  • the spacer 9 is preferably tubular or tubular, in particular thin-walled, hollow and / or flexible. In the illustrated embodiment, it consists of a material with a dielectric constant ⁇ r less than 2.5, in particular of plastic, such as perfluoroalkoxy polymer or polyethylene.
  • the spacer 9 extends along the cable 1 in the enclosure 8 and ensures that the two groups 10 of the cables 1 remain disconnected. Especially for this purpose, a plurality of spacers 9 are received by the enclosure 8.
  • the envelope 8 holds the cable 1 and spacers 9 preferably non-positively due to their inherent elasticity together. This will be a simple one Mounting the audio cable assembly 7 allows.
  • the serving can 8 as needed also consistently or, closed, possibly even as Heat shrink tubing or the like., Be formed.
  • the enclosure 8 allows a particularly simple installation and adjustment to the respective circumstances.
  • a modular construction of the audio cable assembly 7 with the appropriate number of cables 1 and spacers 9 allows, in addition, also different sizes - In particular in terms of length and diameter - of wrappings. 8 can be used.
  • the cables 1 are preferably each clearly identified to confusion when connecting to avoid.
  • the cable 1 according to the illustration example has an overall dielectric constant ⁇ r less than 2.0, preferably less than 1.8 and in particular less than 1.6. The same applies to the cables 1 in the audio cable arrangement 7.
  • the enclosure 8 of the flat cable assembly or audio cable assembly 7 is preferably woven to achieve the desired inherent elasticity in the transverse direction Longitudinal extension of the cable 1 and 9 spacers to achieve.
  • the individual threads or the like run at least substantially vertically and parallel to said longitudinal extent.
  • Fig. 2 are the threads or the like. Shown only obliquely for purposes of illustration.
  • the spacers 9 only to simplify the Representation about unspecified end sections or terminators 8 serving.
  • the spacers 9 end within the enclosure 8 or in the end pieces, in particular such can be closed, that the spacers 9 do not slip out unintentionally can.
