Definitions

  • the invention relates to a cable for power transmission, such as speaker cables for connecting a speaker to an amplifier, with at least one conductor and connection elements.
  • Two-wire cables are generally provided as the connecting cable between, for example, an amplifier and a loudspeaker, the two wires or conductors running parallel to one another.
  • a transmission cable must possibly be able to transmit considerable power.
  • the information to be transmitted for example modulated music
  • the latter can hardly be guaranteed with conventional loudspeaker cables, because on the one hand the two conductors influence each other and on the other hand they are fully exposed to external interference.
  • music transmitted from such a cable and reproduced by the loudspeaker for example, can be falsified, etc.
  • the invention is therefore based on the object of providing a cable of the type mentioned at the outset which eliminates the deficiencies mentioned and in particular permits transmission of information which is modulated as far as possible in an unadulterated manner while permitting high power transmission.
  • a conductor consists of an inner partial conductor and at least one outer coaxial partial conductor surrounding it and separated from it and separated from one another by a dielectric, the inner and at least one outer partial conductor being electrical on the connection elements are interconnected.
  • One ladder may be can also be formed from a plurality of individual strands or as a high conductor enclosing a dielectric.
  • the outer conductor consists of two layers of individual strands. This configuration improves the transmission properties insofar as at least the outer ring conductor is largely flat and not compact, and thus less interference with the individual fields than with a conventional compact extension of a conductor, while at the same time the cross section or the surface of the outer conductor is quite right is large and, as said, allows a large power transmission.
  • the outer partial conductor is designed as a mesh-like braid.
  • the forward and return conductors usually present in a loudspeaker cable are twisted or stranded in order to further eliminate such inductive influences.
  • the cable 1 according to the invention in the embodiment of FIG. 1 has two individual conductors, namely a lead 2 and a counter or return conductor 3, which are each designed as individual cables 4, 6 twisted or stranded together.
  • the structure of a single cable will be explained using the single cable 4.
  • the cable 4 has a central inner partial conductor or inner conductor 7, which is surrounded by an insulating dielectric 8.
  • An outer partial conductor, outer conductor or ring conductor 9, which surrounds the inner conductor 7, is arranged coaxially with the inner conductor 7 and dielectric 8.
  • the entire arrangement 7 to 9 described is surrounded by external insulation 11.
  • the inner and outer partial conductors 7 and 9 are now not electrically separated from one another, but are electrically connected to one another in the region of connection elements 12.
  • the current can flow through both the inner conductor 7 and the outer conductor 9 and thus power can be transmitted through both partial conductors 7, 9, but on the other hand the information to be transmitted, for example the modulated musical information, in particular on the inner conductor, is not disturbed and in none Impaired, so that in the same way an optimal information as well as performance, as is required with such speaker cables, is guaranteed.
