Definitions

  • the present invention relates to an electronic identification device, in particular intended for controlling access to an enclosed space.
  • the present invention relates to a key comprising an electronic unit and at least one external electrical contact pad electrically connected to this electronic unit.
  • This key is intended to be associated with an electronic lock comprising at least one electrical contact terminal arranged so that this terminal is in contact with the external electrical contact pad of the key when the latter is inserted in the electronic lock.
  • the object of the invention is to provide an identification device comprising a conductive body having first and second substantially parallel faces, an electronic identification unit and an external electrical contact pad provided on each of the first and second faces, these two external electrical contact pads having substantially the same electrical potential and being connected jointly to the electronic identification unit.
  • Another object of the invention is to provide such an identification device which can easily be integrated into a key and which has good resistance to mechanical stresses, in particular to mechanical stresses generated on either of the electrical contact pads. external.
  • the intermediate wall ensures the positioning of the first and second plates and guarantees great strength in the assembly of the various elements necessary for the identification function of the identification device according to the invention. It will also be noted that a particular advantage of the invention results from the fact that no protuberance or projection is generated by the identification device, which is particularly advantageous for a key.
  • FIGS. 1 to 4 an embodiment of an identification device according to the invention will be described below.
  • This device is formed by a key 1 intended to be associated with an electronic lock (not shown) known to those skilled in the art.
  • the key 1 is shown quite schematically without boss or recess provided on its two faces and without teeth provided on the periphery of this key. However, it should be noted that such an arrangement is without other possible together with the various elements necessary for the identification function integrated in the key 1 which will be described below.
  • the key 1 comprises an electronic identification unit 2 and at least two external electrical contact surfaces 4 and 6, these two contact surfaces 4 and 6 being electrically connected to each other and jointly with the electronic unit 2 as will be described more precisely below.
  • the key 1 comprises a first recess 8, a second recess 10 and an opening 12 connecting the two recesses 8 and 10.
  • the opening 12 is arranged in an intermediate wall 14 separating the two recesses 8 and 10.
  • the intermediate wall 14 belongs to the body 16 of the key 1, this body 16 having a first face 18 and a second face 20 parallel to one another. It will be noted that the recesses 8 and 10 are arranged one opposite the other.
  • the opening 12 is provided in the central region of the intermediate wall 14.
  • the key 1 further comprises a first conductive part 22, comprising a plate 24 and a stud 26, and a second conductive part 28 comprising a plate 30 and a projection 32 extending from the central region of the plate 30 in the direction of the plate 24
  • a blind hole 34 is arranged in the part 28 so that the projection 32 has substantially the shape of a ring.
  • the plates 24 and 30 are respectively arranged in the recesses 8 and 10.
  • the stud 26 is forced out into the blind hole 34 through the opening 12. It will be noted more precisely that the projection 32 engages in the opening 12 without being in contact with the side wall thereof and that the stud 26 passes right through this opening. It results from the assembly described above that the conductive parts 22 and 24 are electrically connected to each other.
  • the identification device also includes a plate 38 formed of a non-conductive material and located between the first plate 24 and the intermediate wall 14.
  • This plate 38 has in its central part an opening 40 through which the stud 26 passes.
  • the plate 38 has substantially the radial dimensions of the recess 8. As a result, it positions the part 22 and also the part 28 together with the intermediate wall 14. It will be noted that the opening 40 is substantially aligned with the opening 12 provided in the body 16.
  • the parts 22 and 28 are arranged in the body 16 so that it has no points of electrical contact with this body 16.
  • a first conductive pad 48 arranged in the peripheral zone of this face 46.
  • the pad 48 is held by pressure in abutment against the intermediate wall 14 and therefore in electrical contact with the latter.
  • a second conductive pad 50 In the central zone of the face 46 of the plate 38 is provided a second conductive pad 50, this second pad 50 extending continuously from this central zone into the opening 40 and on the second face 52 of the plate 38.
  • the second pad 50 is held by pressure in abutment against the plate 24 of the part 22 and therefore in electrical contact with this plate 24.
  • the pad 50 is arranged on the face 46 of the plate 38 so that '' it has no point of electrical contact with the intermediate wall 14.
  • the track 50 is arranged on the face 52 of the plate 38 so that it is without electrical contact with the side wall of the recess 8.
  • the plate 38 forms the substrate of a double-sided printed circuit .
  • the electronic unit 2 is arranged on the face 46 of the plate 38, a housing 56 being provided between the plate 38 and the plate 30 for this electronic unit 2.
  • This housing 56 is formed by a through opening provided in the intermediate wall 14 .
  • the electronic unit 2 is electrically connected by electrical connection means 58 to the conductive surface 48 and by electrical connection means 60 to the conductive surface 50. It will be noted that the electronic unit 2 and the electrical connection means 58 and 60 are wrapped in resin 62.
  • FIG. 5 shows an alternative embodiment of the identification device described above. The references already described previously will not be described again here.
  • This variant differs from the embodiment described above by the fact that there is provided an insulating part 66 having substantially the shape of a ring, this insulating part 66 being arranged between the side wall 68 of the plate 24 and the wall side 70 of the recess 8. Similarly, an insulating part 72 is also provided between the lateral surface 74 of the plate 30 and the lateral surface 76 of the recess 10. This insulating part 72 is formed in one piece with the insulating layer 44. According to this variant, the electrical insulation of the conductive parts 22 and 28 is perfectly ensured and the conductive pads 48 and 50 are protected.
  • the insulating parts 66 and 72 may have a certain elasticity so as to absorb mechanical stresses exerted on the faces. 4 and 6 of the plates 24 and 30, while ensuring the maintenance of the electrical contacts described above.
