Definitions

  • the invention relates to an arrangement for electrically connecting a first and a second connection means.
  • the invention relates to an automation device according to the preamble of claim 8 and further relates to an assembly according to the preamble of claim 15, which is suitable for connection to such an automation device.
  • an automation device which has a plurality of modules and a rack.
  • the rack is provided for receiving the modules and for supplying them with an operating voltage, wherein the modules can be plugged into slots of a backplane bus, via which the modules are interconnected.
  • Each slot of the rack has three parallel arranged and provided with a ground potential spring contacts on one edge, which are electrically connected to a terminal of a plug-in module.
  • the present invention has for its object to provide an arrangement of the type mentioned, which allows improved contacting of the connection means. Furthermore, an automation device of the aforementioned Specify type with an improved contacting of the module with an electrical potential of the rack of the programmable controller. In addition, an assembly of the aforementioned type is to be created, which is suitable for use in such an automation device.
  • the bristle connection means are designed as brushes which in various forms, for. B. in the form of round, pot or cone brushes, or may be formed in any other suitable form.
  • a simple or in the case of a wave-shaped formation of the bristles a very good contact with regard to the number of possible contact points is achieved. If the connection means are put together, the bristles interlock and hook one another.
  • the bristles are formed like velcro, whereby the contacting of the bristles is further improved.
  • the bristles of both connection means have to check at their ends, the when mating the connection means interlock.
  • the ends of the bristles of only one connection means with hooks and the ends of the bristles of the second connection means can also be provided with loops.
  • the first and / or the second connection means are formed as a bristle rail.
  • a bristle rail is suitable for use in a rack of an automation device as ground potential rail.
  • connection means for protecting the bristles is provided with a protective casing or a protective housing, prevents the bristles are bent too much. In addition, it is ensured that the risk of injury to a user is essentially excluded.
  • the protective cover of the connection means is designed to be axially movable with respect to the bristles. If the connection means plugged in, the protective sheath moves against the direction of insertion. Upon release of the connection means, the protective sheath shifts over the bristles, whereby the bristles, which have bent too much during the insertion, essentially bend straight again.
  • FIG. 5 a known subrack 1 of an automation device is shown.
  • Components of this subrack 1 are an aluminum support 2, two mounted on this support 2 bus circuit boards 3 and a plastic support 4, through the openings 5 plug-in terminals 6 of the bus circuit boards 3 to the connection side of the rack 1 protrude.
  • only one assembly 7 is shown, which is mounted on one of the plug-in terminals 6.
  • the aluminum support 2 is provided with two ground potential rails 8, to which electrically conductive, resilient contact parts 9 are mounted, which are guided through further openings 10 of the plastic carrier 4. These contact parts 9 contact with connection means of the inserted module 7, whereby this module 7 is connected to the ground potential.
  • a bristle rail 11 ( FIG. 1 ) has a plurality of electrically conductive bristles 12, which are contacted with a likewise having a plurality of electrically conductive bristles 13 having brush 14 of a module.
  • the bristle rail 11 need not necessarily be formed with standing bristles; it is also possible to design these as bristle braid 17 ( FIG. 2 ).
  • the bristle rail 11 and the brush 14 have protective sheaths 15, 16, of which the Protective cover 15 of the brush rail 11 rigid and the protective cover of the brush 14 is designed to be movable ( FIGS. 3 and 4 ).
  • the protective sheath 16 shifts in the opposite direction.
  • the protective cover 15 limits the bending of the bristles 12, 13 at right angles to the sliding direction.
  • the protective cover 16 pushes back over the bristles 13 of the brush 14, whereby the bristles 13 are not accessible to a user and thus the risk of injury is largely excluded.
  • connection means 11, 14 are formed with a plurality of electrically conductive bristles 12, 13. In the event that the requirements for good contact are not so high, it is sufficient to provide only one connection means with a plurality of bristles.
  • the other connection means may in this case be a metallic rail, an inclined wall or a tube.
