·'-■ ./' Die EP Q 245 605 beinhaltet ein derartiges induktives Identifikationssystem bestehend aus einem C: de- oder Datenträger, in dem die für die identifikation ve v.vendete Nummer oder Infoftnatios gespeichert ist, einem Lese- oder Sehieib7Lesekopf, der die induktive Datei-Übertragung mit dem Code- oder Datenträger durchführt und einer A^-w^rteeinheit, die die Informationen aufbereitet, die induktive Datenübertragung steuert und vorzugsweise mit einem übergeordneten Rechner kommuniziert. rj
·'-■ ./' EP 0 245 605 contains such an inductive identification system consisting of a code or data carrier in which the number or information used for identification is stored, a read or write head which carries out the inductive file transfer with the code or data carrier and a processing unit which processes the information, controls the inductive data transfer and preferably communicates with a higher-level computer.

Gemäß den verwendeten Code- oder Datenträger sind zwei prinzipielle Systemvarianten möglich, nämlich entweder nur Lesen oder Schreiben Uiid Lesen.Depending on the code or data carrier used, two basic system variants are possible, namely either read only or write Uiid read.

Der Codeträger besteht dabei aus einem Chip und einer Spule, die mit dem Chip über Anschlüsse verbunden ist. Der Codeträger kann dabei sehr klein und in vielen unterschiedlichen Formen verfügbar sein. Dabei kann der CodeträgerThe code carrier consists of a chip and a coil that is connected to the chip via connections. The code carrier can be very small and available in many different shapes. The code carrier can

$ direkt in das oder auf das zu identifizierende Objekt integriert sein. $ be integrated directly into or onto the object to be identified.

Zum Schutz des Codeträgers gegen Kurzschlüsse und Umwelteinflüsse, die zu einer Beeinträchtigung der Funktion des Codeträgers führen könnten, ist es bekannt, denselben in eine Form einzulegen, die mit Gießharz ausgegossen wird.To protect the code carrier against short circuits and environmental influences that could impair its function, it is known to place it in a mold that is filled with casting resin.

• Diese Art des Schutzes des Codeträgers ist jedoch ungenügend. Die Nahtstelle• However, this type of protection of the code carrier is insufficient. The interface

zwischen Form und Gießharz ist nicht absolut wasserdicht oder dicht gegen Fluide; in dieser Grenzzone kann es durch Umwelteinflüsse zur Beschädigungbetween the mould and the casting resin is not absolutely watertight or impermeable to fluids; in this border zone, environmental influences can cause damage

und Ablösung des Gießharzes von der Form kommen, so daß beispielsweise Wasser zum Codeträger gelangen kann, was wiederum zu einem elektrischen Kurzschluß führen kann. Deshalb ist die Versiegelung des Codeträgers innerhalb einer Form mittels eines Gießharzes nicht ausreichend dicht gegen Umwelteinflüsse, wie aggressive fluide oder gasförmige Medien.and detachment of the casting resin from the mold can occur, so that, for example, water can get to the code carrier, which in turn can lead to an electrical short circuit. Therefore, sealing the code carrier within a mold using a casting resin is not sufficiently tight against environmental influences, such as aggressive fluid or gaseous media.

Der Erfindung liegt die Aufgabe zugrunde, einen Codeträger der eingangs genannten Gattung zu schaffen, der gegen wechselnde Umwelteinflüsse wie Feuchtigkeit, Temperatur oder aggressive Medien abgeschirmt ist, der ausreichend dicht gegen Umwelteinflüsse und der insbesondere wasserdicht ist, ohne daß die magnetischen Eigenschaften beeinträchtigt werden.The invention is based on the object of creating a code carrier of the type mentioned at the outset which is shielded against changing environmental influences such as humidity, temperature or aggressive media, which is sufficiently sealed against environmental influences and which is in particular waterproof, without the magnetic properties being impaired.

Die Lösung dieser Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Eine weitere vorteilhafte Ausgestaltung der Erfindung ist im Unteranspruch 2 gekennzeichnet.This object is achieved according to the invention by the features of claim 1. A further advantageous embodiment of the invention is characterized in subclaim 2.

Der Codeträger, der erfindungsgemäß mit einer thermoplastischen oder duroplastischen Umhüllung allseitig und nahtlos versehen ist, besitzt den hervorstechenden Vorteil, daß diese Umhüllung den Codeträger gegen wechselnde Umwelteinflüsse, wie Temperatur, Feuchtigkeit oder aggressive gasförmige oder flüssige Medien vollständig abschirmt, ohne dessen induktive Werte bei der induktiven Übertragung zu beeinträchtigen Insbesondere besitzt der erfmdungsgemäße Codeträger den Vorteil, daß derselbe über lange Zeit wasserdicht und entsprechend dem gewählten thermoplastischen oder duroplaste sehen Kunststoffmaterial auch hitzeunernpfindlich ist und einen erhöhten Druck standzuhalten imstande ist. Zum Beispiel kann nunmehr eiu derartiger Codeträger für Objekte zu deren Identifikation oder Markierung verwendet werden, die in feuchter oder nasser Atmosphäre, unter erhöhter Temperatur und sogar unter erhöhtem Druck zum Einsatz gelangen. Dadurch wird der Anwendungsbereich derartiger Codeträger für ein induktives Identifikations-The code carrier, which according to the invention is provided with a thermoplastic or thermosetting plastic covering on all sides and seamlessly, has the outstanding advantage that this covering completely shields the code carrier against changing environmental influences, such as temperature, humidity or aggressive gaseous or liquid media, without affecting its inductive values during inductive transmission. In particular, the code carrier according to the invention has the advantage that it is watertight for a long time and, depending on the thermoplastic or thermosetting plastic material selected, is also heat-resistant and can withstand increased pressure. For example, such a code carrier can now be used for identifying or marking objects that are used in a moist or wet atmosphere, at elevated temperatures and even under elevated pressure. This expands the area of application of such code carriers for inductive identification.

system erheblich erweitert, deshalb kann nunmehr ein derartiges Identifikationssystem auch bei Objekten angewendet werden, bei denen bisher der Codeträger aufgrund der gegebenen extremen Umweltbeeinflussung am Objekt selbst nicht eingesetzt werden konnte, weil ansonsten der Codeträger bzw. dessen Umhüllung in kürzester Zeit beeinträchtigt oder zerstört worden wäre.system has been significantly expanded, which is why such an identification system can now also be used on objects where the code carrier could not previously be used due to the extreme environmental influences on the object itself, because otherwise the code carrier or its casing would have been impaired or destroyed in a very short time.

Eine derartige Umhüllung des Codeträgers aus einem thermoplastischen oder duropiastischen Kunststoffmateriai wird in Spritzwerkzeugen hergestellt, die je eine Aussparung aufweisen, innerhalb derselben der Codeträger in geeigneter Weise quasi freistehend oder freischwebend für den Umhüllungsvorgang gehaltert ist.Such a covering of the code carrier made of a thermoplastic or duropiastic plastic material is produced in injection molding tools, each of which has a recess within which the code carrier is held in a suitable manner, quasi free-standing or free-floating, for the covering process.

Ein Beispiel der Erfindung ist in der Zeichnung dargestellt und anschließend beschrieben. Dabei zeigen:An example of the invention is shown in the drawing and described below.

Figur 1 einen schematischen Querschnitt durch einen Codeträger mit allseitiger, nahtloser Umhüllung undFigure 1 shows a schematic cross-section through a code carrier with all-round, seamless covering and

Figur 2 einen Codeträger innerhalb eines Spritzwerkzeuges zur Bewerkstelligung des thermoplastischen Umspritzens des Codeträgers.Figure 2 shows a code carrier within an injection molding tool for carrying out the thermoplastic overmolding of the code carrier.

Gemäß der Figur 1 besteht ein Codeträger 1 aus einem Ferritkern 2, der eine Spule 3 aufweist. Auf der der Spule 3 gegenüberliegenden Hauptoberfläche des Ferritkerns 2 ist ein Chip 4 angeordnet, der mit der Spule 3 über (nicht geze:gte) Anschlüsse elektrisch verbunden ist. Der Ferritkern 2, die Spule 3 und der Chip 4 sind nun mittels einer Umhüllung 5 allseitig nahtlos umschlossen, die aus einem thermoplastischen oder duroplastischen Kunststoffmaterial besteht.According to Figure 1, a code carrier 1 consists of a ferrite core 2 which has a coil 3. A chip 4 is arranged on the main surface of the ferrite core 2 opposite the coil 3 and is electrically connected to the coil 3 via connections (not shown ). The ferrite core 2, the coil 3 and the chip 4 are now seamlessly enclosed on all sides by means of a casing 5 which consists of a thermoplastic or thermosetting plastic material.

Zur Herstellung dieser Umhüllung 5 wird gemäß der Figur 2 der Codeträger in ein Spritzwerkzeug eingebracht, welches beispielsweise aus den beiden Teilen 6 und 7 besteht, die jeweils eine einander zugewandte Aussparung 8,9 aufweisen.To produce this casing 5, the code carrier is introduced into an injection molding tool according to Figure 2, which consists, for example, of the two parts 6 and 7, each of which has a recess 8, 9 facing one another.

innerhalb denselben der Codeträger 11 fixiert ist. Diese Fixierung kann in bekannter Weise mittels Fixierstiften 10, 10', 10" geschehen, die den Codeträger 11 in der Mitte der Aussparungen 8,9 plazieren, so daß der Codeträger 11 allseitig innerhalb der Aussparung 8,9 freisteht bis auf die AbstUtzflächen durch die Fixierstifte 10, 10', 10".the code carrier 11 is fixed within them. This fixing can be done in a known manner by means of fixing pins 10, 10', 10", which place the code carrier 11 in the middle of the recesses 8,9, so that the code carrier 11 is free on all sides within the recess 8,9 except for the support surfaces by the fixing pins 10, 10', 10".

Über eine Öffnung 12 innerhalb des Teils 6 des Spritzwerkzeugs kann der iherniöplasiisehe Kunststoff zugeführt werden, der nun den Codeträger &Pgr; allseitig umhüllt. Solange das Kunststoffmaterial noch eine bestimmte Fließfähigkeit besitzt, aber schon so fest ist, daß der Codeträger 11 nicht mehr innerhalb des Werkzeugs zu Boden sinkt, werden die Fixierstifte 10, 10', 10" aus der Aussparung 9 des Werkzeugteils 7 herausgezogen, so daß der fließende Kunststoff den bisherigen Raum der Fixierstifte ausfüllt und den Codeträger 11 nahtlos auch in diesen Bereichen umschließt.The herniated plastic can be fed through an opening 12 within the part 6 of the injection mold, which now envelops the code carrier 11 on all sides. As long as the plastic material still has a certain flowability, but is already so solid that the code carrier 11 no longer sinks to the bottom within the tool, the fixing pins 10, 10', 10" are pulled out of the recess 9 of the tool part 7, so that the flowing plastic fills the previous space of the fixing pins and encloses the code carrier 11 seamlessly in these areas too.

Zur Herstellung einer duroplastischen Umhüllung eines Codeträgers kann ein duroplastisches Kunststoffmaterial gleichzeitig mit dem Codeträger in eine Form entsprechend derjenigen der Figur 2 gebracht und erhitzt werden.To produce a thermosetting plastic covering for a code carrier, a thermosetting plastic material can be formed into a shape corresponding to that shown in Figure 2 and heated at the same time as the code carrier.
