Definitions

  • the invention relates to an electrical device having a connection point for an electrical Anschlußlei- ter having conductor track.
  • the invention also relates to a method for connecting an electrical connection conductor to such an electrical device.
  • connection conductor of a module with a conductor track assigned to it must be electrically conductively and mechanically durable connected at a connection point.
  • connection point ie the area in which the electrical connection must take place, is surrounded by an electrically insulating housing which isolates individual interconnects from one another and from the outside.
  • the size of the electrical device and thus the space available for the connection space within the housing is limited for economic reasons.
  • connection of the module or the connecting conductor with the further leading into the device or within the device running track requires sufficient accessibility for the tools required for the preparation of the electrical connection, such as welding electrodes or positioning aids. Due to the limited accessibility of the connection points, it is therefore often necessary to connect the connection conductors to the conductor tracks at a stage of the device assembly in which the accessibility of the connection points is not yet compensated by further components of the electrical connection. device is prevented or impeded. This requires in many cases an expensive construction of the production means.
  • the invention is based on the object to provide an electrical device with a connection point for an electrical connection conductor having conductor, in which a secure electrical and mechanical connection of the conductor to the connection conductor is possible even with limited accessibility of the connection point.
  • the invention is based on the object to provide a method for connecting an electrical connection conductor to a conductor track of such an electrical device.
  • the object of the invention is achieved with the features of claim 1, according to which a connection point of a conductor of an electrical device is formed by a passage, which is introduced into the conductor track.
  • the conductor track and the electrical connection conductor can be exactly fixed by inserting the electrical connecting conductor into the passage to each other and this can be welded to the passage without an additional pressing or pressing of the conductor track and connecting conductor is required. This eliminates the need for complex auxiliary tools for positioning and the welded connection can be easily carried out even with limited space inside the electrical device, in particular with non-contact methods.
  • the bead formed by the passage also the temperature entry during fusion welding is reduced. If a non-contact welding process is used, for example TIG welding, plasma welding or laser welding, a reliable electrical connection is possible even in extremely confined spaces.
  • the assembly can be substantially facilitated if the passage has an insertion aid for the insertion of the electrical connection conductor.
  • the object is achieved with an electrical device having the features of claim 4, according to which the electrical connection conductor is inserted into the passage and welded thereto.
  • connection point electrical trace of an electrical device with an inserted into a passage forming the passage electrical connection conductor before or after the welding
  • an electrical device for example a power contactor
  • a power contactor is generally provided with a plurality of conductor tracks 4, which lead into the interior of the electrical device 2 or extend inside the electrical device 2.
  • the conductor tracks 4, for example flat metal rails or metal sheets, are fixed in the electrical device 2.
  • the conductor 4 For electrical contacting of a lead, for example, to the outside or to another device-internal module connecting lead 6, the conductor 4 has a connection point 8, which by a in the conductor track 4 introduced passage 10 is formed.
  • the passage 10 is produced, for example, in that an opening is made in the conductor track 4 and the edge of the opening is then deformed by a drawing die, so that a sleeve-shaped projection 12 is created.
  • the passage 10 is provided by a chamfer or by a radius with a Ein Industriesschräge or insertion aid 18, which facilitates the insertion of the connecting conductor 6 in the opening formed by the passage 10.
  • the passage 10 and thus the conductor 4 with the connection conductor 6 ellg 20 are connected to each other via a fusion welding.
  • the shape of the passage 10 may be selected, for example, round or rectangular, so that the method of the invention according to FIG. 3 is suitable both for round as well as according to FIG. 4 for square wires 6.
