Definitions

  • the invention relates to an identification device of the type defined in the precharacterizing part of claim 1.
  • a device of this type is disclosed in FR-A-2 297 525.
  • Identification devices of the type mentioned above can be used for sending interrogation pulses to transponders carried for example by animals and receiving data transmitted by the transponders as reaction to the interrogation pulses. Since the range of the signals transmitted by the transponders is not very large the antenna of the identification device is so constructed that it can easily be brought into the vicinity of a transponder to be interrogated. However, this makes the antenna bulky and long, so that the identification device cannot easily be transported. In particular in mobile use, for example by veterinary surgeons or government inspectors, this would however be desirable.
  • the antenna coupling systems available fail due to soiling.
  • the known antenna couplings have a galvanic connection and the plug-type connections used are easily soiled.
  • bending of the connection contacts can easily occur so that the entire identification device then no longer functions.
  • an identification device It is therefore desirable to equip an identification device with a contactless antenna coupling.
  • This can be implemented basically with an antenna coupling with inductive coupling.
  • the particular problem is encountered here of making the inductively coupled antenna coupling mechanically stable and electrically functionable even under rough ambient conditions.
  • the device according to the invention has the advantage that the antenna is always automatically mounted in a position correctly disposed with respect to the transmitter and receiver section.
  • an antenna coupler is obtained which is largely insensitive to soiling. If for example in the disassembled state dirt particles should get into the insert region of the transmitter and receiver section on assembly they are engaged by the front end of the insert member and conveyed into the hollow chamber formed between the insert member and insert region. This makes it possible to prevent dirt particles getting between the diaphragms covering the transformer halves. A penetration of dirt particles during the engaged state is prevented in advantageous manner by the hood provided on the antenna side.
  • E cores may also be employed for the cores.
  • An identification device 10 consists according to the schematic representation in Fig. 1 substantially of a transmitter and receiver section 12 and an antenna 14.
  • the transmitter and receiver section 12 and the antenna 14 are detachably connected to each other via an antenna coupling 16.
  • the antenna 14 is bent at its free end and is preferably connected via the antenna coupling 16 to the transmitter and receiver section 12 in such a manner that the bent portion of the antenna 14 points obliquely downwardly when the identification device 10 is in a horizontal position.
  • the entire identification device 10 may be held at a grip 17.
  • a ring antenna may also be employed.
  • Figs. 2 and 3 the preferred second embodiment of the antenna coupling 16 is shown.
  • an insert region 50 is disposed into which an antenna-side insert member 52 can be inserted.
  • the insert region 50 has a rectangular cross-section, the cross-sectional area being substantially in two stages. In the outer portion of the insert region the cross-sectional area is broader than in the inner portion of the insert region 50, as can be seen in Fig. 3.
  • the insert member 52 is fixed in the insert region 50 by a snap means consisting of projections 56 which are arranged in the insert region 50 and which can enter detent engagement with recesses 58 correspondingly provided in the insert member 52.
  • the first pot core half 20 is disposed in a side wall 54 of the insert region 50 behind the diaphragm 26.
  • the second pot core half 22 is arranged in the insert member 52 in such a manner that in the engaged state of the insert member 52 it lies opposite the first pot core half 20.
  • a projection 64 is formed on the side of the insert member 52 lying opposite the second pot core half 22. Said projection bears in the engaged state on a side wall of the insert region 50, the cross-sectional area of which as described above is small compared with that of the outer insert region.
  • the purpose of reducing the cross-sectional area is for the insert member 52 to be easily insertable in the outer insert region without resistance whilst in the inner insert region it must be fixed in a position in which a defined gap is set between the two pot core halves 20 and 22. This is ensured by bearing of the projection 64 on the wall portion of the insert region 50 corresponding thereto.
  • a gap is formed between the two pot core halves and corresponds substantially to the thickness of the two diaphragms 26 and 28.
  • the embodiment shown in Figs. 2 and 3 is distinguished in particular by its robustness; it withstands mechanical stresses particularly well.
  • This embodiment in particular is made insensitive by a simple constructional form also to soiling which in the region of the antenna coupling 16 can otherwise easily lead to functional disturbance.
  • a protection against soiling is first formed by an antenna-side hood 62 which in the engaged state covers the opening of the insert region 50.
  • a cavity 60 is formed in the engaged state between the insert member 52 and the insert region 50 . The latter serves to receive any dirt particles possibly present in the insert region 50 prior to insertion of the insert member 52, said particles being pushed along the insert region 50 by the inserted insert member 52 into the cavity 60.
  • a pot core transformer is used.
  • an E core transformer may also be employed.
  • Fig. 4 an embodiment of the antenna 14 is shown which is advantageous in particular when the relatively long antenna must be folded into a handy form.
  • the antenna 14 is divided into two parts and can be folded together about a joint 100.
  • a tube member 102 is displaceably arranged in such a manner that in the collapsed antenna it is retracted into a tube member and in the assembled antenna 14 projects into the two antenna tube members so that the latter can no longer be pivoted about the joint 100.
  • the tube member 102 is longitudinally displaceable in the antenna tube in the direction of the arrow a and oppositely to said direction via a stirrup member 104 projecting out of a slot provided in the antenna 14.
