Definitions

  • the invention concerns a conductor rail, comprising a bearing structure, an insulator and a conductor or conductors.
  • the invention also concerns the method of producing the conductor rail.
  • One already-known electricity rail or electrical current rail described in the FI lay-open publication 69730, comprises a metal rail, U-shaped in cross-section, to which two electrical current conductors are attached by means of plastic holding strips in the longitudinal direction.
  • Another already known conductor rail or contact rail consists of a supporting rail, made from extruded aluminium for example, and longitudinal insulation strips attached to each side wall of the rail, containing grooves into which e.g. copper conductors are sunk.
  • the current-collecting rail has two comb-shaped insulation parts facing each other n which the electrical conductor rails are held in the correct form.
  • an earth conductor is placed in the cu rent rail .
  • Another already-known rail solution is described in the FI patent publication 65874 in which the rail is formed from a duct channel made e.g. from anodized aluminium by press casting. Extending through this rail is an insulation container, inside of which the conductors are placed.
  • the conductor rail consists of an insulator, which acts as the bearing structure and is made by the pultrusion method, and a conductor or conductors set in place in connection with the pultrusion.
  • the purpose of the present invention is to achieve a conductor rail solution which allows the bending of the rail.
  • the extrusion method is applied in the conductor rail solution used in this invention.
  • the extrusion method means such a method by which continuous plastic products are produced in a longitudinal direction, for example by heating a thermoplastic material until it becomes soft, pressing it into a dense mass and forcing it through a nozzle which gives it a desired form.
  • the purpose of the invention is to achieve a conductor rail, produced by the extrusion method, in which the conductor or conductors are inserted after extrusion, thus allowing the bending of the rail in any direction whatsoever (creating the possibility of making three- dimensional forms without additional pieces) prior to inserting the conductors, or also after it, as will later be explained.
  • a conductor rail according to the invention is that linking pieces are not needed, as the conductors may be inserted afterwards (e.g. in order to join two conductor rails together it is necessary only to attach the rails end-to- end on a base, and to insert the conductors, e.g. directly from a reel, into the grooves in the insulator) .
  • the use of linking or additional pieces is possible with a conductor rail according to the invention, if required.
  • Another advantage of the solution according to the invention is that a switch or switches may easily be installed in the conductor rail at any point whatsoever, because the conductors may also be easily inserted as many separate pieces.
  • Additional reinfo cements may also be easily installed on a conductor rail according to the invention, if required.
  • the conductor rail according to the invention may be shaped into any desired form for various purposes, such as for attachment mechanisms, channel for cables or for attachment to another rail.
  • a conductor rail according to the invention is easily dismantled and the conductors may be easily removed, whence the rail may be reformed, if required.
  • the rail is completely recyclable.
  • a conductor rail according to the invention may also be made directly, in that the conductors are placed in their grooves automatically after extrusion.
  • a conductor rail according to the invention can be made in such a way that the grooves formed in the rail for the conductors are very slightly too large for the conductors to be used.
  • a conductor rail made according to the invention may easily be bent even when the conductors are already set in place. The conductors will then be able to adapt to the bending of the rail by sliding a little in their grooves in a longitudinal direction, and will thus not essentially prevent bending.
  • Figure 1 shows schematically a conductor rail according to the invention which is rectangular in its cross-section.
  • Figure 2 shows schematically a conductor rail according to the invention which is oval in its cross-section.
  • Figure 3 shows schematically a conductor rail according to the invention which is round in its cross-section.
  • Figure 4 shows schematically a conductor rail according to the invention which is triangular in its cross-section.
  • Figure 5 shows schematically a conductor rail according to the invention which is equipped with a protective cover .
  • Figure 6 shows an example of one bending possibility with a conductor rail solution according to the invention.
  • Figure 7 shows schematically the linking of two conductor rails .
  • Figure 8 shows schematically the positioning of separate conductor lengths .
  • Figure 9 shows schematically a conductor rail according to the invention which is equipped with additional reinforcement.
  • the conductor rail 10 shown in Figure 1 consists of a bearing structure 13 and an insulating structure 11.
  • the conductors 12 are inserted after the insulating structure 11 is made.
  • the conductors 12 are located in grooves in the insulation stucture 11, as shown in Figure 1.
  • Figure 2 shows a conductor rail 10 whose bearing structure 13 is oval in its cross-section. Grooves for the conductors 12 are formed in the insulating structure 11.
  • Figure 3 shows a conductor rail 10 which is round in cross- section and contains conductors 12 in grooves in the insulating part 11 of the bearing structure 13.
  • Figure 4 shows a conductor rail 10 which is triangular in cross-section and contains conductors 12 in grooves in the insulating part 11 of the bearing structure 13.
  • the conductor rail 10 shown in Figure 5 has the same structure as the conductor rail shown in Figure 1, but is equipped with a protective cover 14.
  • Figure 6 shows a conductor rail 10 corresponding in structure to the conductor rail 10 shown in Figure 1, but bent by way of example in all three dimensions, at 90 degree angles from each othe .
  • the conductor rail arrangement shown in Figure 7 consists of two conductor rails 10 linked to each other without a linking piece.
  • the perception of the invention is to join the conductor or conductors to a bearing and insulating structure made by the extrusion method especially after the structure has first been made in the desired form.
  • thermosetting plastics or thermoplasts are softened thermoplastics such as PVC, ABS, polypropylene or polyethylene, all of which are economically priced.
  • polycarbonate and acrylic resins are suitable for the raw material of the conductor rail.
  • thermosetting plastic to use as the raw material of a conductor rail according to the invention is polyester .
  • a conductor rail according to the invention may, if required, use fibres (in separate slivers) such as glass fibre or aramid fibre, i.e. kevla , as a reinforcement.
  • a conductor rail according to the invention may be economically produced and bent into the desired form as shown in Figures 1-8.
  • the conductor rail cross-sections shown in the drawings are mainly symmetrical, a conductor rail may also be produced with an asymmetrical cross-section, for example in that one part of the rail (the gripping part) is considerably thicker than the other part.
  • a conductor rail according to the invention can thus be made advantageously and easily in accordance with safety regulations.
  • all possibly necessary devices for protecting form or access, or any protective covers may be easily shaped if made from plastic, and the plastic is also automatically an insulator, thus giving extra security.

Abstract

Rail conducteur comprenant une structure porteuse (13), un isolateur (11) et un ou des conducteurs (12). La structure porteuse (13) et l' isolateur (11) constituent une même structure fabriquée par extrusion en une seule passe et les conducteurs (12) sont insérés dans le rail après l'extrusion, ce qui permet de cintrer le rail à chaud ou à froid dans toute direction avant ou après insertion des conducteurs (12).
