Definitions

  • the present invention relates generally to the electrical connections that an electrical device inevitably comprises for its connection, whether it is its external connection or whether it is an internal connection occurring between two of its constituents .
  • connection uses a multi-strand electrical conductor to be connected to a metal part.
  • the metallic core of the electrical conductor is wound, transversely, around a clamping member, such as a rivet or screw, attached to the metallic piece, then clamped axially against the latter by this clamping member.
  • a clamping member such as a rivet or screw
  • the electrical connection provided by such a connected assembly may be more or less faulty, if the electrical conductor is subjected to untimely traction and if other protective measures are not otherwise provided for in this regard.
  • the present invention generally relates to a provision which, while advantageously leading to a particularly economical embodiment of a connected assembly of the kind in question, makes it possible to avoid the above drawbacks.
  • the present invention thus firstly more specifically relates to a connected assembly of the kind comprising a metal part to which is connected the metal core of a multi-strand electrical conductor, this connected assembly being generally characterized in that, the metal part comprising at least locally two sheets superposed on each other and assembled to one another by at least one rivet coming from the same thickness of these sheets, the metallic core of the electrical conductor is pinched between the sheets in line with this rivet, with at least some of its strands which bypass this rivet in a substantially axial plane for this one ; it also relates to the method for producing this connected assembly and any electrical appliance comprising a connected assembly of this type.
  • connection process according to the invention advantageously takes place even during the assembly process of the two sheets belonging to the metal part to be connected or forming it, simultaneously with this assembly process.
  • a connected assembly 10 comprises, overall, a metal part 11 to which is connected the metal core 12 of a multi-strand electrical conductor 13.
  • multi-strand electrical conductor 13 is understood to mean, in the usual manner, an electrical conductor 13, the metallic core 12 of which is formed by a bundle of strands 14, which, in principle, are, at least initially, generally rectilinear and parallel.
  • the metal part 11 comprising, at least locally, two sheets 15A, 15B superimposed on one another and assembled to one another by at least one rivet 16 coming from the same thickness of these sheets 15A, 15B, the metallic core 12 of the electrical conductor 13 is pinched between these sheets 15A, 15B in line with this rivet 16, with some, at least, of its strands 14, if not all of these, which bypass this rivet 16 along a substantially axial plane for the latter.
  • the rivet 16 is formed by two hollow bosses 17A, 17B, of cross-section, for example circular, which, each coming from the sheets 15A, 15B respectively, result from a joint stamping of these sheets 15A, 15B, according to the technique known as "clinching", and which, of complementary shape, and of the same axis A, are sufficiently intimately fitted one inside the other to ensure by mechanical connection the desired assembly for the sheets 15A, 15B.
  • the sheets 15A, 15B are brought closer to each other, according to the arrows F in this FIG. 5, until they are superposed one on the other, and that they are then jointly stamped under conditions leading to the creation, on the hollow bosses 17A, 17B, and as is visible in FIGS. 4 and 5, of an undercut reinforcing the resistance of the assembly along the axis A of the rivet 16 formed.
  • the stripped end of the metallic core 12 of the electrical conductor 13 is inserted, in line with the location chosen for the formation of the rivet 16, as shown schematically by a simple contour 16 'in Figure 5.
  • the two sheets 15A, 15B are simultaneously assembled and the electrical connection of the electrical conductor 13 to the metal part 11 which they form.
  • the connected assembly 10 is formed, in its entirety, of two sheets 15A, 15B, which, in practice, are both simple superimposed metal strips.
  • these two sheets 15A, 15B are assembled by at least one other rivet 16, at a distance from the first.
  • the connected assembly 10 forms, jointly, in a single piece, at a distance from one and the other of the rivets 16, and, more precisely, between these, another constituent 18.
  • this other component 18 comprises at least one cell 19, and, in practice, in alignment with one another, three cells 19, for the constitution of the active part of a socket-outlet. current.
  • Each of the cells 19 results from a local deformation 20A, 20B, in an arc, from one and the other of the sheets 15A, 15B.
  • these cells 19 are suitable for the engagement of the pins 21 of a socket outlet duly matched to the socket socket which thus forms the component 18.
  • the connected assembly 10 according to the invention belongs in this case for example to a power strip.
  • the present invention is moreover not limited to the embodiment described and shown, but encompasses any variant, in particular as regards the cross section of the rivet or rivets intervening between the sheets concerned, this cross section does not not necessarily being circular.
