Description

Die Erfindung betrifft eine lösbare Steckvorrichtung für Datenkabelverbindungen mit einer Magnetcodierung.The invention relates to a detachable connector for data cable connections with a magnetic coding.

Steckvorrichtungen oder Steckverbinder sind weithin bekannt. Bei den bekannten Steckverbindern besteht jedoch die Problematik, daß entweder eine Verpolungssicherung nicht gewährleistet ist oder diese durch mechanische Maßnahmen gewährt wird. Durch Einsatz von übermäßiger Kraft ist es aber möglich, dennoch den Stecker in den Steckverbinder einzubringen. Hierdurch wird zumeist der Steckverbinder beschädigt.Connectors or connectors are well known. Both known connectors, however, there is the problem that either a Reverse polarity protection is not guaranteed or this by mechanical Measures are granted. By using excessive force, however, it is possible to nevertheless insert the plug into the connector. Hereby the connector is usually damaged.

Andererseits ist bekannt, daß oftmals Schäden an Datenkabelverbindungen vorkommen, welche lösbar sind, da durch unsachgemäßes Lösen oder Herstellen der Verbindung Schäden hervorgerufen werden. Es ist dann insbesondere häufig der Fall, daß das Kabel ab Gehäuse eines Gerätes abreißt, das Gerät vom Aufstellungsort gerissen wird, etc. In Call-Centern kommt es oft vor, daß ein Nutzer eines Head-Sets im "Eifer des Gefechtes" von der Verkabelung des Head-Sets stranguliert wurde, da sich die Kabelverbindung nicht gelöst hat. Außerdem ist es auch schon zu Beschädigungen an den Head-Sets gekommen, da beim Verbinden der Head-Sets unsachgemäß und/oder verpolt der Stecker in der Buchse geführt wurde.On the other hand, it is known that data cable connections are often damaged occur, which are solvable, because of improper loosening or Establishing the connection can cause damage. It is then especially often the case that the cable from the housing of a device tears off, the device is torn from the installation site, etc. In call centers it often happens that a user of a headset in the "zeal of battle" of the wiring of the headset was strangled because the Has not loosened the cable connection. Besides, it's already closed Damage to the head sets came because when connecting the head sets improper and / or polarity reversed the plug was inserted into the socket.

Außerdem ist bei optischen Kabeln, wie Glasfaserkabeln bzw. POF's (Plastic Optical Fibre) und den zugehörigen Steckverbindern eine exakte mechanische Führung notwendig. In addition, an exact mechanical guide is in optical cables, such as fiber optic cables or POFs (P lastic O ptical ibre F) and the associated connectors necessary.

Aufgabe der Erfindung ist es, eine Steckvorrichtung derart auszugestalten, daß eine Verpolungssicherung gegeben ist, sowie eine mechanische Beschädigung des Steckers beim Einstecken in die Buchse oder beim Lösen aus der Buchse vermieden.The object of the invention is to design a plug device such that reverse polarity protection is provided, as well as mechanical damage of the plug when plugging into or out of the socket avoided.

Diese Aufgabe wird durch die Merkmale des Anspruches 1 und 8 gelöst. Vorteilhafte Ausgestaltungen der Erfindung ergeben sich durch die abhängigen Ansprüche sowie die weitere Beschreibung.This object is solved by the features of claims 1 and 8. Advantageous embodiments of the invention result from the dependent Claims and the further description.

Die erfindungsgemäße Steckvorrichtung besteht aus einem Stecker und einer zugehörigen Buchse. Der Stecker weist mindestens eine magnetische Codierung in Form von Dauermagneten auf, welche zueinander eine unterschiedliche magnetische Polung haben. Dies bedeutet, daß mindestens ein Dauermagnet magnetischen Nordpol, der andere magnetische Südpol aufweist.
Zentral im Stecker ist ein Kontaktfeld angeordnet. Dieses Kontaktfeld weist Kontaktstifte auf. Jeder Kontaktstift ist über eine Feder gelagert. Beim Einsetzen in die Buchse werden die Kontaktstifte des Kontaktfeldes des Steckers durch die Federn in die zugehörigen Kontaktmulden des Gegenkontaktfeldes der Buchse gedrückt. Die Kontaktstifte können in bzw. auf den Federn in vorteilhafter Weise derart gelagert sein, daß diese bei der Kontaktierung eine leichte Rotationsbewegung um die eigene Längsachse ausführen und hierdurch ein Selbstreinigungseffekt zwischen den Kontaktstiften und den Kontaktmulden zustande kommt. Dies erhöht langfristig die Kontaktierungssicherheit.
The plug device according to the invention consists of a plug and an associated socket. The plug has at least one magnetic coding in the form of permanent magnets, which have a different magnetic polarity to one another. This means that at least one permanent magnet has a magnetic north pole and another magnetic south pole.
A contact field is arranged centrally in the plug. This contact field has contact pins. Each contact pin is supported by a spring. When inserted into the socket, the contact pins of the contact field of the plug are pressed into the associated contact recesses of the mating contact field of the socket by the springs. The contact pins can advantageously be mounted in or on the springs in such a way that they make a slight rotational movement about their own longitudinal axis when making contact and this results in a self-cleaning effect between the contact pins and the contact recesses. This increases contact security in the long term.

Auf diese Weise ist ein leichter kontaktbehafteter Steckverbinder, der magnetisch gehalten wird und bei dem die Abreißkraft der magnetisch gehaltenen Verbindung zwischen einer Quelle zu Senke (Stecker zu Buchse) um eine Größenordnung geringer ist als die Ausrißkraft der an Quelle und/oder Senke angebrachten Kabelverbindung. Hierdurch wird erreicht, daß die Verbindung jederzeit durch Zug am Kabel ohne Zerstörung ortsfester oder beweglicher Einrichtungen möglich ist. Die Verbindung wird hierdurch, in eingeschränktem Maße, zerstörungssicher (vandalensicher).In this way, a light contact connector is the is kept magnetic and in which the tearing force of the magnetic held connection between a source and sink (plug to socket) is an order of magnitude less than the pull-out force of the source and / or Sink attached cable connection. This ensures that the Connection at any time by pulling on the cable without destroying it stationary or moving devices is possible. The connection is hereby, in limited, non-destructive (vandal-proof).

Der bewegliche Teil (Senke) ist leicht und ohne spitze Kanten ausgeführt, dass durch ihn, auch bei hohen Beschleunigungswerten, wie sie etwa in einem Fahrzeug oder durch Zug am Kabel auftreten können, keine Verletzungen an mitreisenden Personen verursacht werden. Die Größe der Steckverbindung ist hierbei jenseits der für Kleinkinder verschluckungsgefährichen Grenze gewählt.The moving part (sink) is light and executed without sharp edges that through it, even with high acceleration values, such as those in a Vehicle or by pulling on the cable, no injuries accompanying persons are caused. The size of the connector is chosen here beyond the limit that can be swallowed by small children.

Durch gepolte Magnete alleine oder in Verbindung mit rotationssymmetrischen Ausformungen an der Oberfläche wird eine eindeutige Orientierung und Positionierung der Verbindung erzwungen. Die Ausformung der Oberfläche jedoch beeinflußt die Haltekraft der Verbindung nicht wesentlich.By means of polar magnets alone or in connection with rotationally symmetrical ones Formations on the surface become a clear orientation and Forced positioning of the connection. The shaping of the surface however, does not significantly affect the holding force of the connection.

Die Signalkopplung zwischen Buchse und Stecker erfolgt entweder mittels Übertragerspulen, folglich kontaktlos, oder mittels gefederter Kontakte.The signal coupling between socket and plug is done either by means of Transmitter coils, consequently contactless, or by means of spring-loaded contacts.

Bei galvanisch getrennter Übertragung kann das Informationssignal in einer der bekannten analogen oder digitalen Modulationsverfahren auf einer Trägerschwingung aufgebracht sein. Zur Demodulation und Signalverstärkung sind dann dedizierte Baugruppen erforderlich, die ihre Versorgungsspannung aus dem Trägersignal gewinnen.In the case of electrically isolated transmission, the information signal can be in one of the known analog or digital modulation methods on a Carrier vibration can be applied. For demodulation and signal amplification Dedicated modules are then required that match their supply voltage gain from the carrier signal.

In einer besonders vorteilhaften Ausgestaltung der Erfindung ist bei einer eindeutigen Positionierung und Orientierung der beiden Übertragerhälften zueinander auch eine direkte Signalübertragung - ohne Modulation - von mehreren getrennten Signalen mit reduziertem Übersprechen möglich.In a particularly advantageous embodiment of the invention, one clear positioning and orientation of the two transmitter halves to each other also a direct signal transmission - without modulation - from multiple separate signals with reduced crosstalk possible.

Die Buchse weist die gleiche Anzahl an magnetische Codierungen wie der Stecker auf. Beim Zusammenfügen von Stecker und Buchse kommen die magnetischen Codierungen aufeinander zu liegen. Die magnetischen Codierungen der Buchse sind zu den magnetischen Codierungen des Steckers entgegengesetzt gepolt.
Die magnetische Codierung des Steckers weist beim richtigen Zusammenfügen des Steckers eine umgekehrte Polung auf als die zugehörige magnetische Codierung der Buchse.
Die magnetische Codierung ist jeweils als ein Dauermagnet ausgestaltet, welcher mit seiner Nord- oder Südpolung die Oberfläche des Steckers abschließt.
Auf diese Weise wird der Stecker, durch die magnetischen Kräfte der Dauermagneten nur in einer definierten Position einrasten. Zugleich ist gewährleistet, daß durch die Anziehungskraft der entgegengesetzt gepolten Dauermagneten in Buchse und Stecker sich diese anziehen und, insbesondere bei galvanischer Konatktierung, verpolungssicher Stecker und Buchse kontaktieren.
Im weiteren wird die Erfindung anhand einer galvanischen Kontaktierung ausführlich beschrieben.
Die Buchse weist ein Kontaktfeld auf, welches auf die Form des Kontaktfeldes des Steckers und den zugehörigen Kontaktstiften in der Formgebung paßt.
The socket has the same number of magnetic codes as the plug. When the plug and socket are put together, the magnetic codes come to rest on one another. The magnetic codings of the socket are opposite to the magnetic codings of the connector.
When the plug is assembled correctly, the magnetic coding of the plug has an opposite polarity than the associated magnetic coding of the socket.
The magnetic coding is designed as a permanent magnet, which closes the surface of the plug with its north or south polarity.
In this way, the plug will only snap into a defined position due to the magnetic forces of the permanent magnets. At the same time, it is ensured that the attraction of the oppositely polarized permanent magnets in the socket and the plug attract them and, in particular in the case of galvanic contacting, contact the plug and the socket with reverse polarity.
The invention is described in detail below with the aid of galvanic contacting.
The socket has a contact field which fits the shape of the contact field of the plug and the associated contact pins in the shape.

Beim Lösen der Verbindung muß lediglich die magnetische Anziehungskraft der Magneten überwunden werden, so daß das Lösen der Verbindung ohne mechanische Schäden erfolgt.When loosening the connection, only the magnetic attraction of the Magnets can be overcome, so that the connection without loosening mechanical damage occurs.

Im weiteren wird die Erfindung anhand eines konkreten Ausführungsbeispieles näher erläutert.Furthermore, the invention is based on a specific embodiment explained in more detail.

It shows:

FIG 3
is a schematic representation of the mating contact field of the socket.

Die Steckvorrichtung 1, gemäß FIG 1, besteht aus einem Stecker 2 und einer Buchse 3. Der Stecker 2 weist ein Kontaktfeld 4 auf. Das Kontaktfeld 4 ist in einer Vertiefung auf der Oberfläche des Steckers eingearbeitet. Im weiteren ist in die Oberfläche des Steckers eine magnetische Codierung 6, 7 eingearbeitet. Bei der magnetischen Codierung 6 handelt es sich beispielsweise um einen Dauermagneten, der mit seiner Nordpolung die Oberfläche zum Stecker 2 abschließt. Bei der magnetischen Codierung 7 handelt es sich beispielsweise um einen Dauermagneten mit Südpolung, der mit seiner Südpolung die Oberfläche zum Stecker 2 abschließt. Der Stecker 2 ist aus elektrisch nicht leitenden Kunststoff hergestellt. Das Kontaktfeld 4 besteht aus mehreren einzelnen Kontaktstiften 10, welche aus dem Kontaktfeld 4 herausragen. Die Kontaktstifte 10 lagern jeweils auf einer Feder 11, welche die Kontaktstifte 10 aus der Ebene des Kontaktfeldes 4 herausstehen lassen.
Zugleich ist hierdurch gewährleistet, daß die Kontaktstifte 10 über die zugehörigen Federn 11 stets mit einer definierten Kraft beim Zusammenfügen von Stecker 2 und Buchse 3 in die Kontaktmulden 12 des Gegenkontaktfeldes 5 der Buchse 3 gehalten werden.
The plug device 1, according to FIG. 1, consists of a plug 2 and a socket 3. The plug 2 has a contact field 4. The contact field 4 is worked into a recess on the surface of the plug. Furthermore, a magnetic coding 6, 7 is incorporated into the surface of the plug. Magnetic coding 6 is, for example, a permanent magnet which, with its north polarity, closes off the surface of connector 2. Magnetic coding 7 is, for example, a permanent magnet with south polarity, which with its south polarity closes off the surface of connector 2. The connector 2 is made of electrically non-conductive plastic. The contact field 4 consists of several individual contact pins 10 which protrude from the contact field 4. The contact pins 10 each rest on a spring 11, which let the contact pins 10 protrude from the plane of the contact field 4.
At the same time, this ensures that the contact pins 10 are always held in the contact recesses 12 of the mating contact field 5 of the socket 3 with a defined force via the associated springs 11 when the plug 2 and socket 3 are joined together.

Die Buchse 3 besteht aus einem Gegenkontaktfeld 5, welches erhaben auf der Oberfläche der Buchse 3aufgesetzt ist. Im weiteren sind magnetische Codierungen 8, 9 vorgesehen. Bei der magnetischen Codierung 8 handelt es sich beispielsweise um einen Dauermagneten, der mit seiner Süddpolung die Oberfläche zur Buchse 3 abschließt. Bei der magnetischen Codierung 9 handelt es sich beispielsweise um einen Dauermagneten mit Südpolung, der mit seiner Südpolung die Oberfläche zur Buchse 3 abschließt.
Das Gegenkontaktfeld 5 der Buchse 3 mit den Kontaktmulden 12 ist auf die Formgebung und die Kontaktstifte 10 des Kontaktfeldes 4 des Steckers 2 angepaßt. Beim Zusammenfügen von Stecker 2 und Buchse 3 erfolgt durch die gegenpolige Codierung der magnetischen Codierungen 6 und 7 des Steckers 2 zu den Codierungen 8 und 9 der Buchse 3 eine magnetische Anziehung des Steckers 2 in die Buchse 3. Hierdurch wird gewährleistet, daß der Stecker durch die magnetische Kraft in einer definierten Position mit der Buchse 3 zusammengeführt wird. Ein Verdrehen ist vermieden, da dann die magnetische Codierung des Steckers 2 und der Buchse 3 nicht übereinstimmt und die magnetischen Codierungen 6, 7 des Steckers 2 sich von den magnetischen Codierungen 8, 9 der Buchse 3 abstoßen. Der Stecker 2 kann dann nicht in die Buchse 3 gesteckt werden.
The socket 3 consists of a mating contact field 5, which is raised on the surface of the socket 3. Magnetic codes 8, 9 are also provided. The magnetic coding 8 is, for example, a permanent magnet which, with its south polarity, closes the surface to the socket 3. Magnetic coding 9 is, for example, a permanent magnet with south polarity, which with its south polarity closes the surface of socket 3.
The mating contact field 5 of the socket 3 with the contact recesses 12 is adapted to the shape and the contact pins 10 of the contact field 4 of the plug 2. When joining plug 2 and socket 3, the opposite polarity coding of the magnetic codes 6 and 7 of the plug 2 to the codes 8 and 9 of the socket 3 results in a magnetic attraction of the plug 2 in the socket 3. This ensures that the plug is through the magnetic force is brought together in a defined position with the socket 3. Twisting is avoided since the magnetic coding of the connector 2 and the socket 3 then does not match and the magnetic codes 6, 7 of the connector 2 repel the magnetic codes 8, 9 of the socket 3. The plug 2 can then not be inserted into the socket 3.

In einer vorteilhaften Ausgestaltungsform der Erfindung ist die Buchse 3 in einen Sitz in einem Fahrzeug integriert. Der Stecker 2 ist an einem Kopfhörer angeschlossen. Durch die magnetische Codierung kann ein Laie den Stecker 2 nur in einer, der codierten Form, in die Buchse 3 einführen.In an advantageous embodiment of the invention, the socket 3 is in integrated a seat in a vehicle. The connector 2 is on a headphone connected. The layman can use the magnetic coding to plug 2 insert only in one, the coded form, into the socket 3.

Andererseits ermöglicht die erfindungsgemäße Ausgestaltungsform, daß bei versehentlichem Lösen der Kabelverbindung, über den Stecker 2 und die Buchse 3, sich die Steckverbindung für den Nutzer verletzungssicher und komfortabel trennt und zugleich eine mechanische Beschädigung an Stecker 2 und/oder Buchse 3 vermeiden wird.On the other hand, the embodiment according to the invention enables that at accidental loosening of the cable connection, via connector 2 and Socket 3, the connector for the user safe and injury disconnects easily and at the same time mechanical damage to connector 2 and / or socket 3 will be avoided.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung dient der Stecker 2 und die Buchse 3 zur Verbindung von Glasfasern bzw. Plastic Optical Fibres. Durch die magnetischen Codierungen 6, 7, 8, 9 im Stecker 2 und in der Buchse 3 und der mechanischen Ausgestaltung des Steckers 2 und der Buchse 3 ist eine hochpräzise mechanische Passgenauigkeit gegeben. Diese ist bei einer Steckvorrichtung zur Verbindung von zwei Plastic Optical Fibres notwendig, da jede Ungenauigkeit zu Leistungsverlusten des im Kabel zu übertragenden Signals führt. Zur weiteren exakten Passgenauigkeit der zu koppelnden Plastic Optical Fibres sind im Gegenkontaktfeld 5 die Kontaktmulden 12 in Vertiefungen geführt, in welchen die Plastic Optical Fibres mit liegen. Aus dem Kontaktfeld 4 des Steckers 2 ragen die Plastic Optical Fibres um den Wert heraus, welcher der Vertiefung im Gegenkontaktfeld 5 entspricht, dies beträgt jedoch maximal einen Millimeter. Die Plastic Optical Fibres im Stecker 2 stellen folglich die Kontaktstifte dar und auf diese Weise ist eine exakte mechanische Koppelung möglich.
Auf diese überraschend einfache Weise ist es möglich mehrere Plastic Optical Fibres mit einer erfindungsgemäßen Steckvorrichtung 1 zu koppeln.
In a further advantageous embodiment of the invention, the plug 2 and the socket 3 serve to connect glass fibers or plastic optical fibers. The magnetic codings 6, 7, 8, 9 in the connector 2 and in the socket 3 and the mechanical design of the connector 2 and the socket 3 provide a high-precision mechanical fit. This is necessary in the case of a plug-in device for connecting two plastic optical fibers, since any inaccuracy leads to a loss in performance of the signal to be transmitted in the cable. For further exact fitting accuracy of the plastic optical fibers to be coupled, the contact troughs 12 are guided in recesses in the counter-contact field 5, in which recesses the plastic optical fibers lie. The plastic optical fibers protrude from the contact field 4 of the plug 2 by the value which corresponds to the depression in the counter-contact field 5, but this is a maximum of one millimeter. The plastic optical fibers in connector 2 thus represent the contact pins and in this way an exact mechanical coupling is possible.
In this surprisingly simple way, it is possible to couple several plastic optical fibers with a plug device 1 according to the invention.
