Definitions

  • the present invention relates first of all to a metal profile for producing a conductive, for example movable, element of a two-way switch assembly, the movable element being provided with two electrical contact surfaces arranged to cooperate alternately, respectively. with one and the other of two contact surfaces provided respectively on two fixed conductive supports, arranged on either side of the movable element.
  • the present invention aims to further reduce the costs of producing conductive elements of switches, and in particular mobile elements.
  • the present invention relates to a metal profile for the production of a conductive element with double contact face, intended to be cut into pieces, or electrical contacts, characterized in that it is made of a multi-metallic material, that it comprises a base, arranged to bear and be fixed on one face of the conductive element, and a body extending on either side of the base and comprising at least two surface layers of precious metal on which are formed respectively two opposite contact surfaces.
  • the present invention also relates to a method for producing a conductive element with a movable blade and with a double contact face.
  • Document DE-B-1 260 646 already discloses a method for producing a conductive element with a movable blade and with a double contact face, in which a metal piece is cut off, a notch is cut in a blade, at one of its ends, the piece is introduced into the notch of the blade, so that the piece protrudes from the two opposite faces of the blade, and the piece is fixed on the blade.
  • the present invention aims to overcome these drawbacks.
  • the present invention relates to a method of the type mentioned above, characterized in that it is in a prefabricated profile with double contact face and formed in one piece that the piece is cut, and qu 'we put the piece of support on the edges of the notch after having introduced the piece in the notch of the blade and before fixing it on the blade.
  • the present invention finally relates to a conductive element with a movable blade and with a double contact face, characterized in that it is produced according to this method.
  • the section 15 shown in Figure 1 is intended to be cut into pieces that will be fixed, or better welded, on a fixed or mobile element, but preferably mobile, of a two-way switch, which will be discussed below .
  • This profile comprises a central body 1, of substantially rectangular cross section, and a base 2.
  • the base 2 is constituted by two wings 3 and 4, in the extension of one another, and arranged perpendicular to the plane of symmetry 5 of the profile 15, projecting from the side walls 6, 7 of the profile 15.
  • the two contact edges 8 and 9 of the body 1, perpendicular to the walls 6, 7 are substantially curved for reasons discussed below.
  • the two wings 3 and 4 extend at a level of the body 1 located between the two edges 8 and 9 but closer to the edge 8 than the edge 9, so that the difference between the distance, from the edge 9 to the face is wings 3 and 4 facing this edge 9, and the distance from edge 8 to the face of wings 3 and 4 facing this edge 8, is practically equal to the thickness of a conductive element intended to receive a section of the profile 15.
  • the face of the wings 3 and 4, facing the most distant edge 9, comprises at least one welding boss 10, 11.
  • the thickness of the wings 3 and 4 is relatively small to be able to weld them on a conductive element, but nevertheless sufficient to ensure the mechanical connection between a section of profile and this conductive element.
  • the body and the base of the profile 15, which therefore has a substantially cruciform cross section, are formed from a first ordinary metallic material, offering good weldability with the material of the conductive support elements. It can be copper, nickel or any other metal or similar alloy. At least one second metallic material covers, for example following a lamination, and over a very small thickness, the ordinary metal material of the profile 15, at the edges 8 and 9, to form two thin surface layers 12 and 13, intended to ensure the electrical switching contact. These layers 12 and 13 are made of precious metal, or a precious metal alloy, for example silver.
  • Profile 15, as described above, is a bimetallic profile. It should however be noted that the invention relates to a multimetal profile, for example bimetallic or trimetallic. In the case of a trimetallic profile, the surface layers of precious metal may have an even smaller thickness than in the case of a bimetallic profile, of the order of ten microns.
  • FIG. 2 shows a mobile conductive element with double contact face 100 of a two-way switch assembly, further comprising two fixed conductive supports 102 and 103, arranged on either side of the element 100.
  • the element 100 is constituted by a conductive support strip capable of alternately occupying two stable positions bearing against one and the other of the two conductive supports 102 and 103.
  • a notch, or lumen, 105 of width equal to or slightly greater than the width of the body 1 of the profile 15, and of length equal to or greater than the length of the piece 106, previously cut into the profile 15 and received on the blade 100.
  • the notch 105 is preferably arranged fungitudinafement has your blade 100, on either side of the median plane of the blade, and extends from l free end 107 of the blade.
  • the part of the body 109 of the piece 106 comprising the layer of precious metal 13 furthest from the wings 3 and 4 crosses the notch 105, so that the wings 3 and 4 are in abutment against the face 108 of the blade 100 opposite to this layer 13, and that the two parts 109 and 110, projecting respectively from the wings 3 and 4 and from the blade 100, from the body of the piece 106 have the same height, or thickness.
  • the mobile conductive element with double contact, or active double face, of FIG. 2 is produced in the following manner.
  • the piece 106 After cutting the piece 106 in the profile 15 using simple automated equipment, and cutting the notch 105 in the blade 100, the piece 106 is introduced in the notch 105 until the base (2, 3, 4) of the piece 106 comes to bear on the edges of the notch 105 of the blade 100, and the two wings 3 and 4 are preferably fixed on the blade 100 by a double electro-resistive welding , at the welding bosses 10 and 11, to ensure the mechanical and electrical connection of the piece 106 and the blade 100.
  • welded contact pads 20 and 30, respectively On the fixed conductive support elements 102 and 103 are welded contact pads 20 and 30, respectively. They each consist, and in a known manner, of a section of simple profile, for example bimetallic, and slightly curved in their contact part of precious metal, opposite their welding surface, itself provided with welding bosses. (21, 31).
  • the pads 20 and 30 are arranged to cooperate alternately with the layer 12 and the layer 13 of the pad 106 of the movable blade 100.
  • the pads 20 and 30 are arranged orthogonally to the pad 106, so that the three pads in question having curved contact surfaces, their cooperation two by two achieves a point contact of high electrical reliability.
