Definitions

  • the present invention relates to an arrangement of a first busbar and a second busbar for electrically connecting electrical conductors and/or assemblies.
  • the present invention also relates to a method for electrically connecting at least two such busbars.
  • a generic arrangement is from DE 699 06 233 T2 known.
  • the technological background is also the DE 10 2009 018 945 A1 and the DE 10 2012 212 907 A1 called.
  • Busbars are used to connect electrical conductors and/or assemblies. At the connection points of the busbars to each other and to the conductors and/or assemblies, the electrical contact must be permanently and reliably ensured. Depending on the area of application, for example in the manufacturing industry, the connection should also be able to be carried out quickly and easily in order to enable the assemblies and systems to be quickly retrofitted.
  • Busbars are regularly screwed, welded or riveted to one another. Attention must be paid to the materials used, in particular the screws and/or sleeves, so that contact is guaranteed over the long term with possibly different materials despite different temperature and corrosion behavior. The contact to electrical conductors is often made by means of a crimp connection. Screwing, welding or riveting are relatively expensive connection techniques.
  • the pamphlet DE 20 2013 103 444 U1 shows, for example, a W-shaped contact element whose three contact tulips are provided for the electrical connection of busbars of a bus system, in particular that is routed externally.
  • the print DE 20 2013 104 785 U1 is an approximately S-shaped clamping spring for electrically connecting busbars used in particular externally guided bus system with series modules of a series module arrangement.
  • springs can be assembled and detached more quickly than a screw connection, but in the event of a particularly significant vibration load, they can possibly become detached automatically over the long term. Depending on the area of application, it is not always necessary for the connection to be detachable.
  • the object of the present invention is therefore to provide an arrangement and a method with which busbars can be connected to one another permanently, easily, quickly and reliably.
  • the conductor rails of this arrangement can be produced very inexpensively from flat strip material as a stamped and bent component.
  • a sheet of copper or aluminum is preferably used for this.
  • embossing can be carried out very quickly and easily using an embossing tool.
  • the busbars are not detachably connected to one another in a non-destructive manner.
  • the preferred choice of busbars of the same material ensures long-term contact.
  • the contact head of the contact receptacle of the busbars is longer in the joining direction than the contact head of the contact tab of the busbars.
  • the contact tab can be moved in and against the joining direction before the busbars are stamped together. This enables tolerance compensation in the joining direction when the busbars are assembled with one another.
  • the contact lugs of the busbars are preferably designed to correspond to the contact receptacles of the busbars.
  • the contact lugs of the busbars each have a contour that is designed to correspond to the contour of the contact receptacles. This allows the contact tab of a Busbar are inserted, inserted or snapped into the correspondingly designed contact receptacle of the other busbar.
  • the busbars are constructed in the same way. However, it is also preferred that busbars that have a different cross section and/or the number of contact lugs and/or contact receptacles are different are combined with one another.
  • the first busbar has only one or more contact receptacles, with the second busbar having only one or more contact lugs.
  • the busbars are each flat, linear or L-shaped, S-shaped or U-shaped in cross section. In the case of an L-, S- or U-shaped cross-section, the busbars have at least two surfaces which can be used for arranging at least one contact tab and/or at least one contact receptacle.
  • the flat, linear, L-shaped, S-shaped or U-shaped busbars can be combined with one another as desired.
  • a width of the contact tab is preferably almost the same as or only slightly smaller than a width of the contact receptacle, at least at points or in certain areas. As a result, the contact tab fits almost exactly into the contact in this area. During embossing, the mechanical form fit and electrical contact are established at least in this area. In this way, in particular two contact points or contact areas lying opposite one another can be specifically defined. The current path is then routed from one busbar through defined contact points or areas to the second busbar.
  • the contact tab and/or the contact receptacle of the busbars each have a contact neck on which the contact head is arranged.
  • the contact tab When the contact tab is pushed in, inserted or snapped into place in a joining direction in the contact receptacle, the contact tab snaps into the contact receptacle due to the contour tapering on the contact neck. It is then held captive without already being embossed and cannot automatically become detached from the contact in the opposite direction to the joining direction.
  • the busbars each comprise two surfaces on which at least one contact lug, preferably two contact lugs, and/or in which at least one contact receptacle, preferably two contact receptacles, are arranged. It is also preferred that the at least one contact tab and/or the at least one contact receptacle of one of the two surfaces is offset in the longitudinal direction relative to the at least one contact tab and/or the at least one contact receptacle of the other of the two surfaces. This allows multiple busbars to be nested.
  • a U-shaped configuration of the busbars is particularly preferred. Two U-shaped busbars can then be arranged one above the other. An interior space surrounded by the busbars is preferably used for electrically contacting attachment of electrical conductors.
  • a possible conductor rail for such an arrangement has at least one surface that extends in a longitudinal direction and in a direction of extension. Furthermore, it has at least one contact tab extending from an edge of the surface and/or at least one contact receptacle arranged in the surface.
  • the contact lug and/or the contact receptacle of the busbar are provided for embossing with a contact receptacle and/or a contact lug of another corresponding busbar.
  • busbars can be detached and connected to one another very quickly and inexpensively, without destroying them. If the same material is used for both busbars, the electrical contact between the busbars is permanently ensured due to the same temperature behavior and the same corrosion behavior of the busbars.
  • the embossing of claim 8 can be carried out advantageously and simply with an embossing stamp which is placed onto the contact tab perpendicular to the surface of the contact tab and widens it radially so that it is radially inward the inner circumference of the contact creates, which can be held down accordingly.
  • Fig.1(a) shows an arrangement 10 of a first busbar 1 and a second busbar 1 'of a first embodiment according to the invention in an unassembled state U.
  • the busbars 1, 1' are U-shaped in cross section. They extend in a longitudinal direction 31 and surround an interior space 100 which can be used for arranging electrical conductors (not shown) so that they make electrical contact.

  • the conductor rails 1, 1' are formed in one piece as a stamped and bent component from sheet metal.
  • the leg surfaces 12, 12', 13, 13' are formed by bending the metal sheet at approximately a right angle (not shown) relative to the connecting surface 11, 11'. Therefore, the leg surfaces 12, 13, 12', 13' are each connected to the connecting surface 11, 11' at a bending edge 171, 172, 171', 172', which extends in the longitudinal direction 31.
  • a contour of the contact lugs 15 ′ of the second busbar 1 ′ is designed to correspond to a contour of the contact receptacles 14 of the first busbar 1 , so that the contact lugs 15 ′ each fit into the contact receptacles 14 .
  • the contact receptacles 14 each extend from the bending edge 171, 172 into the leg surface 12, 13 of the first busbar 1.
  • the contact receptacles 14 of the opposing leg surfaces 12, 13 each have the same distance A1, A2 from one another.
  • the contact receptacles 14 of one of the two leg surfaces 12, 13 are offset in the longitudinal direction 31 relative to the contact receptacles 14 of the other of the two surfaces 12, 13 by an offset ⁇ A relative to one another.
  • two contact lugs 15' are arranged in an analogous manner.
  • the contact tabs 15' also have the same spacing A1', A2' from one another on the leg surfaces 12', 13'.
  • the contact tabs 15' of one of the two leg surfaces 12', 13' are offset in the longitudinal direction 31 relative to the contact tabs 15' of the other of the two surfaces 12', 13' by an offset ⁇ A' relative to one another.
  • the offset ⁇ A, ⁇ A' is the same for both busbars 1, 1'.
  • the busbars 1, 1' can be arranged one above the other.
  • they can also be nested with one another, so that they are arranged diagonally one below the other.
  • further busbars (not shown) can also be connected to these two busbars 1, 1'. Only the contact tabs 15' of one of the two leg surfaces 12', 13' of the second busbar 1' are connected to the contact receptacles 14 of one of the two leg surfaces 13, 12 of the first busbar 1.
  • busbars 1, 1' of different widths and/or lengths can also be connected to one another, as long as the spacing A1, A2, A1', A2' of the contact lugs 15' and the contact receptacles 14 is designed to match one another, and the contours of the contact lugs 15 'And the contacts 14 correspond to each other.
  • both the contact tabs 15' and the contact receptacles 14 each have a contact head 152', 142 and a contact neck 151', 141.
  • the contact neck 151', 141 is narrower than the contact head 152', 142 in each case.
  • the contact tab 15 ′ has a smaller contour overall than the contact receptacle 14 , so that it can be inserted or snapped into the contact receptacle 14 .
  • the contact tab 15' After the contact tab 15' has been inserted or engaged in the contact receptacle 14, the contact tab 15' can no longer slip out of the contact receptacle 14 counter to the joining direction 30 due to the narrowing of the contact receptacle 14 at its contact neck 141.
  • the second busbar 1' is then fastened to the first busbar 1 in a captive manner even without being stamped.
  • Fig.1(b) shows the arrangement 10 of Fig.1(a) during assembly.
  • the contact lugs 15 'of the second busbar 1' are engaged in the contact receptacles 14 of the first busbar 1.
  • a first of the two contact lugs 15 ′ of one of the two leg surfaces 13 ′ of the second busbar 1 ′ is shown in the contact receptacle 14 of the first busbar 1 .
  • the contact tab: 15' has not yet been embossed with the contact receptacle 14, so that the busbars 1, 1' on this contact tab 15' and contact receptacle 14 are not yet mechanical are connected to one another in a form-fitting manner and also not yet defined in an electrically contacting manner.
  • the second section (II) shows the first of the two contact tabs 15' and their contact receptacle 14 during stamping with a stamping tool 2.
  • a counter tool (not shown) is arranged in the interior 100 (not visible here) that holds the contact tab 15' in the contact receptacle 14.

  • FIG. 2 shows in (a) a further embodiment of an arrangement 10 according to the invention in the connection state V and in (b) an enlarged detail from (a). It can be seen that the extension 143 of the contact head 142 of the contact receptacle 14 of the first busbar 1 is significantly larger than in FIG Fig. 1 (d) . As a result, the contact lug 15' of the second busbar 1' can be displaced significantly further in or against the joining direction 30.
