Preferably this process leaves no lasting traces, so that both components are preferably not changed by the plugging and subsequent peeling.
  • Known examples of such connectors are conventional connectors for connecting and disconnecting electrical lines. In electrical connectors, one distinguishes the male part of a connector (with outwardly facing pins) from the female part (with inwardly facing contact holes) (http://en.wikipedia.org/wiki/Connectors). There are also connectors with plug-in elements of both sexes.
  • the invention provides that the connector according to the invention comprises at least one elastic and electrically conductive fastener
  • an elastic fastening element is to be understood as a structural element of an arrangement according to the invention, which serves for fastening, in particular for improving the holding force and the stability of a plug connection according to the invention, since this fastening element is capable of a reversible change in shape due to its elastic properties the mating of the connector is the construction of a force that prevents the improper disengagement of the connector after mating the connector, or at least makes it difficult.
  • the elastic fastener is constantly under a pressure that continuously sustains the mating of the connector caused reversible deformation of the elastic fastener, whereby the force built upon mating of the connector force after mating the connector continuously prevents the improper disengagement of the connector or at least more difficult.

  • the peg-shaped structure, the hollow structure and the at least one elastic and electrically conductive fastening element are designed such that the elastic and electrically conductive fastening element can be placed when mating the connector between mating walls of the peg-shaped structure and the hollow structure.
  • a peg-shaped structure is to be understood as meaning a raised shape that points outward from the surface of the carrier of this structure and that is designed in such a way that it is peg-shaped Structure is suitable in conjunction with a matching hollow structure to form a connector.
  • a hollow structure fitting to a peg-shaped structure is to be understood as meaning a shape pointing inward into the surface of the support of this structure, preferably a depression, which is designed such that this hollow structure interacts with a peg-shaped one matching to it Structure is suitable for forming a plug connection.

  • At least one sliding contact element is a carbon brush.
  • Carbon brushes preferably graphite-based, are preferred sliding contact elements in many applications, among other reasons because they are significantly softer than metals.
  • the mechanical properties of graphite make this material particularly suitable for a plug connection.
  • the electrical conductivity of this material is also sufficient for numerous applications.
  • an arrangement is provided in which at least one fastening element consists at least partially of an elastic plastic.
  • an elastic plastic is to be understood as meaning an elastic solid whose material is produced at least partially synthetically or semisynthetically preferably from monomeric organic molecules by polymerization of these molecules (so-called polymer plastic or simply "polymer”).
  • Elastic polymers are also referred to as elastomers. By pressure or elongation elastomers can change their shape elastically; Upon completion of compression or stretching, the elastomer quickly regains its original shape (http://en.wikipedia.org/wiki/Plastic_Elastomere).
  • the elastomers include in particular all types of crosslinked rubber.
  • the crosslinking is preferably carried out by vulcanization with sulfur, by means of peroxides, metal oxides or by irradiation.
  • the elastomers are predominantly cross-linked and therefore flexible. They do not soften when heated and are insoluble in most solvents. Therefore, they are used for, for example, hygiene articles or chemical gloves.
  • the rubber compound of car tires is also an elastomer which obtains its properties by vulcanization.
  • elastomers are natural rubber (NR), acrylonitrile-butadiene rubber (NBR), styrene-butadiene rubber (SBR), chloroprene rubber (CR), butadiene rubber (BR) and ethylene-propylene-diene rubber (EPDM ).
  • Elastic plastics may be electrically conductive or made electrically conductive by additives. Plastics are generally considered excellent insulators. That's because polymers are the basic requirement for electrical conductivity, quasi-free electrons, completely missing. By adding substances (doping), which either supply electrons to the chain (reduction) or by means of removal (oxidation) create free sites for the movement of electrons, it is possible to produce electrically conductive polymers. For example, polyacetylene and poly (p-phenylene) become electrically conductive when doped with bromine, iodine or perchloric acid. Other important electrically conductive polymers are polyaniline doped with hydrochloric acid and polypyrrole from anodic oxidation.
  • Conductive polymers also called electrically self-conducting polymers, are plastics with electrical conductivity. This is in contrast to normal polymers that do not conduct electricity. The conductivity of the polymer is achieved by conjugated double bonds, which allow a free mobility of charge carriers. This is in contrast to electrically conductive additives such as aluminum flakes or carbon black, in which the polymer itself does not conduct the electrical current.
  • the structure of the self-conducting polymers (http://de.wikipedia.org/wiki/Leitschreibe_Polymere) is analogous to the conventional plastics highly disordered. They are neither soluble nor decomposable melted. Often, the polymers also deviate from the ideal chemical composition, since in the formation of undesirable side reactions can occur. The structure and thus also the physical properties are strongly influenced by the synthesis conditions. Apart from the monomer used, among other things, the solvent, the conducting salt and the oxidation conditions affect the chemical composition and the morphology of the polymer.
  • the electrical conductivity requires freely movable charge carriers. Therefore, electrically self-conducting polymers have an extended ⁇ -electron system in the form of conjugated double bonds.
  • the charge carriers are hole electrons.
  • An exception is polyacetylene, in which a negatively charged polymer backbone can be produced.
  • anions are incorporated in the polymer. If an electric current flows, the charge carriers must also transfer from one polymer chain to an adjacent one, because the conjugated chains have only a finite length. Therefore, the total resistance is the sum of the resistances in the polymer chains and the resistances between the chains. The greater influence on the electrical conductivity has the higher resistance between the chains. The shorter the conjugated chains, the higher the resistance because the charge carriers must be transferred more often between the chains.
  • the polymer backbone can be reversibly electrochemically oxidized and reduced.
  • the conductivity can be varied from the insulating reduced state to the oxidized conductive state.
  • the oxidation injects holes into the conjugated polymer chains. Initially, the conductivity increases with the number of charge carriers generated. However, overoxidation leads to the irreversible destruction of the conjugation and thus to the loss of electrical conductivity. Since the polymer chains charge positively as a result of the oxidation, anions are incorporated into the polymer layer for charge compensation. During the reduction, they are forced back into the electrolyte solution.
  • the incorporation of cations to maintain the charge neutrality is possible, especially if in the synthesis bulky anions were used, which are stuck in the polymer, for example, polystyrene sulfonate.
  • the term "doping" is also used. This is what the oxidation is called p-doping. However, this is not comparable to the classical doping of inorganic semiconductors. There, foreign atoms are introduced in comparably low concentrations. The oxidation of the polymer backbone, however, generates the charge carriers in a direct way and in a much higher concentration. For thin layers, the color of the conductive polymer depends on the oxidation state.
  • the preparation of electrically self-conducting polymers can be carried out chemically, electrochemically, photoelectrochemically or by CVD (chemical vapor deposition). Apart from different starting compounds that are available, their derivatization or the formation of copolymers allows a broad spectrum of chemical and physical properties to be achieved. Very simple is the electrochemical deposition of thin layers by the oxidation of the monomeric starting material.
  • the self-conducting polymer is produced in the oxidized, conductive state. The positive charges of the polymer backbone are compensated by the incorporation of anions of the conductive salt.
  • Important examples of electrically self-conducting polymers are polyacetylene, polyaniline, polyparaphenylene, polypyrrole and polythiophene.
  • an arrangement according to the invention is provided as part of a power supply to at least one rotating conductor.
