- connection systems can be self-locating within certain limits.
- magnets to make a perfect contact in electrical connection systems, especially when it comes to contacting a plug with a socket, is suitable for many applications.
- the US 2002/086559 A1 discloses a safety coupling for a household appliance.
- the DE 101 49 575 A1 discloses a permanent magnetic multiple socket with terminals for multiple cable plugs.

- the present invention is therefore based on the object, an electrical connection system with a contact elements having plug and a mating contact elements having bush further developed so that a magnetic device to connect the plug with the socket magnetically, even in sensitive areas, especially in medical care institutions used can be.
- the magnetic device has at least one connection pair, which can be attracted by a magnet and a magnet, but not itself composed permanent-magnetic link, wherein in each case the magnet of a pair of links in the socket and the non-permanent magnetic link in the plug is arranged.
- a preferable electronic component or electronic device with a socket as part of an electrical connection system results from claim 5.
- a preferable use of an electrical connection system for connecting a plug to a socket of an electronic, medical device or device in a medical supply device in particular

- the plug now has 20.07.2016 LR / ra no magnet on or the plug has no permanent magnetic material which generates a magnetic field which is suitable to disturb medical units, components or other, in particular vital medical, electrical devices. For example, if the plug falls on a patient's chest, an implanted pacemaker will not be adversely affected by the magnetic field. Nevertheless, all the advantages of a magnetic connection between plug and socket can be used by the solution according to the invention.
- connection between the plug and socket can be easily closed due to the magnetic device, with an exact positioning of the plug relative to the socket can be supported by the magnetic device. Furthermore, the magnetic device makes it possible for the connection between plug and socket to be released automatically as soon as a tensile or bending load is applied to the plug, which exceeds a defined extent. This measure can be controlled by the strength of the magnetic device. In conventional connectors can tear out of the socket in an unwanted tensile or bending stress of the plug and cause mechanical damage there. Furthermore, there is a risk that an unwanted tensile or bending load of the plug leads to the device itself being pulled out of its anchorage or its support and falling down, for example, possibly even on the patient.

That is, it is advantageous if the connection between the plug and the socket is realized only by the magnetic device, ie that no additional mechanical connection, for example a plug connection, is provided. As a result, a simple closing and removal of the plug is realized by the socket. Furthermore, it is ensured that the plug detaches itself from the socket even in the case of abuse without the socket or the device being damaged.

Die Erfindung betrifft ferner ein elektronisches Bauteil oder ein elektronisches Gerät nach Anspruch 5 sowie die Verwendung eines elektronischen Verbindungssystems nach Anspruch 6. Ein gattungsgemäßes elektrisches Verbindungssystem ist aus der
Zur einwandfreien Kontaktierung der Kontaktelemente mit den Gegenkontaktelementen sind in dem Stecker und der Buchse aufeinander ausgerichtete Magnete eingesetzt. Die Magnete im Stecker und der Buchse ziehen sich dabei gegenseitig an und sorgen dafür, dass sich der Stecker magnetisch mit der Buchse verbindet und dabei die Kontaktelemente die Gegenkontaktelemente kontaktieren. Im Regelfall sind jeweils zwei Magnete im Stecker und zwei Magnete in der Buchse vorgesehen.The invention further relates to an electronic component or an electronic device according to
For proper contacting of the contact elements with the mating contact elements aligned magnets are used in the plug and the socket. The magnets in the plug and the socket attract each other and ensure that the plug connects magnetically to the socket while the contact elements contact the mating contact elements. As a rule, two magnets are provided in the plug and two magnets in the socket.
Aus dem allgemeinen Stand der Technik ist es ergänzend oder alternativ zu der Verwendung von Magneten und entsprechenden Gegenmagneten auch bekannt, sogenannte Pressbrücken, zum Beispiel ein Silikonkissen, einzusetzen, um die Kontaktelemente elastisch in Richtung auf die Gegenkontaktelemente vorzuspannen.From the general state of the art, it is also known, in addition or as an alternative to the use of magnets and corresponding counter magnets, to use so-called press bridges, for example a silicone pad, in order to prestress the contact elements elastically in the direction of the mating contact elements.
Die Verwendung von Magneten und Gegenmagneten hat sich als besonders geeignet herausgestellt, um einerseits eine sichere Verbindung zwischen den Kontaktelementen und den Gegenkontaktelementen herzustellen, und andererseits den Verbindungsvorgang zu erleichtern. Derartige Verbindungssysteme können innerhalb gewisser Grenzen selbstfindend sein.The use of magnets and counter-magnets has been found to be particularly suitable, on the one hand to produce a secure connection between the contact elements and the mating contact elements, and on the other hand to facilitate the connection process. Such connection systems can be self-locating within certain limits.
Der Einsatz von Magneten, um bei elektrischen Verbindungssystemen eine einwandfreie Kontaktierung herzustellen, insbesondere wenn es sich dabei um die Kontaktierung eines Steckers mit einer Buchse handelt, eignet sich für viele Anwendungsfälle. Es sind jedoch Anwendungsfälle bekannt, insbesondere in medizinischen Versorgungseinrichtungen bzw. in Krankenhäusern, bei denen die Verwendung von Magneten nicht möglich ist, da es dort zu Situationen kommen kann, bei denen die Magnete lebenswichtige medizinische Einheiten, beispielsweise in den Patienten implantierte Herzschrittmacher, stören.The use of magnets to make a perfect contact in electrical connection systems, especially when it comes to contacting a plug with a socket, is suitable for many applications. However, there are known applications, especially in medical facilities or in hospitals, where the use of magnets is not possible, since there may be situations in which the magnets interfere with vital medical units, such as implanted in the patient pacemaker.
Besonders problematisch ist es dabei, wenn sich ein Stecker beispielsweise durch eine versehentliche Zug- oder Biegebelastung aus einer Buchse löst und auf die Brust eines Patienten fällt, wodurch ein implantierter Herzschrittmacher negativ beeinflusst wird.It is particularly problematic when a plug, for example, by an accidental tensile or bending stress from a socket dissolves and falls on the chest of a patient, whereby an implanted pacemaker is adversely affected.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein elektrisches Verbindungssystem mit einem Kontaktelemente aufweisenden Stecker und einer Gegenkontaktelemente aufweisenden Buchse so weiterzuentwickeln, dass eine Magneteinrichtung, um den Stecker mit der Buchse magnetisch zu verbinden, auch in sensiblen Bereichen, insbesondere in medizinischen Versorgungseinrichtungen, eingesetzt werden kann.The present invention is therefore based on the object, an electrical connection system with a contact elements having plug and a mating contact elements having bush further developed so that a magnetic device to connect the plug with the socket magnetically, even in sensitive areas, especially in medical care institutions used can be.
Diese Aufgabe wird hinsichtlich des elektrischen Verbindungssystems dadurch gelöst, dass die Magneteinrichtung wenigstens ein Verbindungspaar aufweist, welches sich aus einem Magneten und einem von dem Magneten anziehbaren, selbst jedoch nicht permanent-magnetischen Verbindungsglied zusammensetzt, wobei jeweils der Magnet eines Verbindungspaares in der Buchse und das nicht permanent-magnetische Verbindungsglied im Stecker angeordnet ist.This object is achieved with regard to the electrical connection system in that the magnetic device has at least one connection pair, which can be attracted by a magnet and a magnet, but not itself composed permanent-magnetic link, wherein in each case the magnet of a pair of links in the socket and the non-permanent magnetic link in the plug is arranged.
Ein zu bevorzugendes elektronisches Bauteil oder elektronisches Gerät mit einer Buchse als Teil eines elektrischen Verbindungssystems ergibt sich aus Anspruch 5. Eine zu bevorzugende Verwendung eines elektrischen Verbindungssystems zum Verbinden eines Steckers mit einer Buchse eines elektronischen, medizinischen Bauteils oder Gerätes in einer medizinischen Versorgungseinrichtung, insbesondere in einem Krankenhaus, ergibt sich aus Anspruch 6. Dadurch, dass die Magneteinrichtung wenigstens ein Verbindungspaar aufweist, welches aus einem Magneten und einem nicht permanent-magnetischen Verbindungsglied zusammengesetzt ist, und dadurch, dass das nicht permanent-magnetische Verbindungsglied im Stecker angeordnet ist, lassen sich die Vorteile einer Magneteinrichtung zur Herstellung einer Verbindung zwischen einem Stecker und einer Buchse auch in sensiblen Bereichen, insbesondere in medizinischen Versorgungseinrichtungen, insbesondere in Krankenhäusern, realisieren. Durch die erfindungsgemäße Lösung weist der Stecker nunmehr 20.07.2016 LR/ra keinen Magneten auf bzw. der Stecker weist kein permanent-magnetisches Material auf, welches ein Magnetfeld erzeugt, das geeignet ist, medizinische Einheiten, Bauteile oder sonstige, insbesondere lebenswichtige medizinische, elektrische Geräte zu stören. Sollte der Stecker auf die Brust eines Patienten fallen, wird beispielsweise ein implantierter Herzschrittmacher nicht negativ durch das Magnetfeld beeinflusst. Gleichwohl können durch die erfindungsgemäße Lösung sämtliche Vorteile einer magnetischen Verbindung zwischen Stecker und Buchse genutzt werden.A preferable electronic component or electronic device with a socket as part of an electrical connection system results from
Die Verbindung zwischen Stecker und Buchse kann aufgrund der Magneteinrichtung einfach geschlossen werden, wobei eine exakte Positionierung des Steckers gegenüber der Buchse durch die Magneteinrichtung unterstützt werden kann. Ferner ermöglicht es die Magneteinrichtung, dass sich die Verbindung zwischen Stecker und Buchse selbständig löst, sobald eine Zug- oder Biegebelastung auf den Stecker aufgebracht wird, die ein definiertes Maß überschreitet. Dieses Maß lässt sich durch die Stärke der Magneteinrichtung steuern. Bei herkömmlichen Steckverbindern kann bei einer ungewollten Zug- oder Biegebeanspruchung des Steckers dieser aus der Buchse ausreißen und dort mechanische Beschädigungen verursachen. Ferner besteht die Gefahr, dass eine ungewollte Zug- oder Biegebelastung des Steckers dazu führt, dass das Gerät selbst aus seiner Verankerung oder von seiner Auflage gezogen wird und beispielsweise herunterfällt, möglicherweise sogar auf den Patienten.The connection between the plug and socket can be easily closed due to the magnetic device, with an exact positioning of the plug relative to the socket can be supported by the magnetic device. Furthermore, the magnetic device makes it possible for the connection between plug and socket to be released automatically as soon as a tensile or bending load is applied to the plug, which exceeds a defined extent. This measure can be controlled by the strength of the magnetic device. In conventional connectors can tear out of the socket in an unwanted tensile or bending stress of the plug and cause mechanical damage there. Furthermore, there is a risk that an unwanted tensile or bending load of the plug leads to the device itself being pulled out of its anchorage or its support and falling down, for example, possibly even on the patient.
Die Verwendung einer magnetischen Verbindung zwischen einem Stecker und einer Buchse reduziert somit Beschädigungen an den mit der Buchse versehenen Geräten und verringert eine Verletzungsgefahr für den Patienten.The use of a magnetic connection between a plug and a socket thus reduces damage the provided with the jack devices and reduces the risk of injury to the patient.
Im Rahmen der Erfindung ist unter einem "nicht permanent-magnetischen Verbindungsglied" zu verstehen, dass dieses kein Dauer- oder Permanentmagnet ist. Es sei darauf hingewiesen, dass magnetisch anziehbare Materialien im Normalfall ihre Magnetisierung zum größten Teil sofort verlieren, wenn das Material aus dem externen Magnetfeld, im vorliegenden Fall dem Magnetfeld des Magneten der Buchse, entfernt wird. Im Allgemeinen bleibt lediglich ein kleiner Restmagnetismus zurück, die sogenannte Remanenz. Es gibt jedoch auch Materialien, bei denen diese Remanenz ziemlich groß ist und eine dauerhafte permanente starke Magnetisierung erreicht wird. Solche Materialien können zu Permanentmagneten magnetisiert werden oder von vornherein als Permanentmagnete existieren, d. h. eine deutlich erkennbare (makroskopische) Magnetisierung dauerhaft annehmen. Dies ist im Rahmen der Erfindung nicht gewünscht, daher fallen Materialien, die, nachdem sie aus dem Magnetfeld des Magneten der Buchse entfernt werden, eine Remanenz aufweisen, die einer dauerhaften (permanenten) starken Magnetisierung entspricht, unter den Begriff Permanentmagnete und nicht unter das Merkmal "nicht permanent-magnetisches Verbindungsglied".In the context of the invention is meant a "non-permanent-magnetic link" that this is not a permanent or permanent magnet. It should be noted that magnetically attractable materials normally lose most of their magnetization immediately when the material is removed from the external magnetic field, in this case the magnetic field of the magnet of the socket. In general, only a small residual magnetism remains, the so-called remanence. However, there are also materials in which this remanence is quite large and a permanent permanent strong magnetization is achieved. Such materials can be magnetized into permanent magnets or exist as permanent magnets from the outset, i. H. permanently adopt a clearly recognizable (macroscopic) magnetization. This is not desired in the invention, therefore, fall materials that, after they are removed from the magnetic field of the magnet of the bush, have a remanence that corresponds to a permanent (permanent) strong magnetization, the term permanent magnets and not under the feature "non-permanent-magnetic link".
Es kommt im Rahmen der Erfindung im Wesentlichen darauf an, dass ein versehentlich oder absichtlich von einer Buchse abgenommener Stecker keine Gefahr für den Patienten oder elektrische, medizinische Geräte und Bauteile wie z. B. Herzschrittmacher darstellt. Daher ist im Rahmen der Erfindung vorgesehen, dass der Stecker über ein zwar magnetisch anziehbares, selbst jedoch nicht permanent-magnetisches Verbindungsglied verfügt, dessen Remanenz so gering ist, dass hiervon keine Gefahr ausgeht.It is within the scope of the invention essentially important that a accidentally or intentionally removed from a socket plug no danger to the patient or electrical, medical devices and components such. B. pacemaker represents. Therefore, it is provided in the invention that the plug via a magnetically attractable, However, it does not have a permanently magnetic link whose remanence is so low that there is no danger.
Von Vorteil ist es, wenn das nicht permanent-magnetische Verbindungsglied ein weichmagnetisches Material ist. Weichmagnetische Materialien werden wieder unmagnetisch, wenn man den Magneten entfernt (gegebenenfalls von einer kleinen Remanenz abgesehen). Im Unterschied hierzu bleiben hartmagnetische Materialien magnetisch, wenn diese lange Zeit neben einem Magneten angeordnet waren.It is advantageous if the non-permanent-magnetic link is a soft magnetic material. Soft magnetic materials become non-magnetic again when the magnet is removed (with the exception of a small remanence). In contrast, hard magnetic materials remain magnetic if they have been placed next to a magnet for a long time.
Von Vorteil ist es, wenn das nicht permanent-magnetische Verbindungsglied durch einen Weicheisenkern gebildet ist.It is advantageous if the non-permanent-magnetic link is formed by a soft iron core.
Allgemein kann das nicht permanent-magnetische Verbindungsglied beispielsweise aus Eisen, Kobalt, Nickel, Gadolinium, Terbium, Dysprosium oder aus geeigneten Legierungen oder Verbindungen bestehen, welche die Eigenschaft erfüllen, selbst dann, wenn diese längere Zeit in einem externen Magnetfeld angeordnet waren, nach dem Entfernen aus dem Magnetfeld keine dauerhafte, permanente, starke Magnetisierung aufzuweisen.In general, the non-permanent magnetic link can be made of, for example, iron, cobalt, nickel, gadolinium, terbium, dysprosium, or suitable alloys or compounds that satisfy the property, even after being left in an external magnetic field for a long time Remove from the magnetic field to have no permanent, permanent, strong magnetization.
Von Vorteil ist es, wenn die Magneteinrichtung zwei oder mehr Verbindungspaare aufweist. Eine Ausbildung von wenigstens zwei Verbindungspaaren hat sich als besonders vorteilhaft herausgestellt, um eine exakte Positionierung des Steckers gegenüber der Buchse zu erreichen.It is advantageous if the magnetic device has two or more pairs of connections. An embodiment of at least two pairs of connections has proven to be particularly advantageous in order to achieve an exact positioning of the plug relative to the socket.
Von Vorteil ist es, wenn der Stecker und die Buchse ausschließlich durch die Magneteinrichtung miteinander verbindbar sind. Das heißt, es ist von Vorteil, wenn die Verbindung zwischen dem Stecker und der Buchse nur durch die Magneteinrichtung realisiert wird, d. h. dass keine zusätzliche mechanische Verbindung, beispielsweise eine Steckverbindung, vorgesehen ist. Dadurch wird ein einfaches Schließen und Entfernen des Steckers von der Buchse realisiert. Ferner wird gewährleistet, dass sich der Stecker selbst im Missbrauchsfall von der Buchse löst, ohne dass die Buchse oder das Gerät beschädigt wird.It is advantageous if the plug and the socket can be connected to one another exclusively by the magnetic device are. That is, it is advantageous if the connection between the plug and the socket is realized only by the magnetic device, ie that no additional mechanical connection, for example a plug connection, is provided. As a result, a simple closing and removal of the plug is realized by the socket. Furthermore, it is ensured that the plug detaches itself from the socket even in the case of abuse without the socket or the device being damaged.
Von Vorteil ist es, wenn die Kontaktelemente derart in den Stecker eingesetzt sind, dass deren Kontaktflächen im Wesentlichen in einer Ebene mit einer der Buchse zugewandten Vorderseite des Steckers angeordnet sind und die Gegenkontaktelemente derart in der Buchse eingesetzt sind, dass deren Gegenkontaktflächen im Wesentlichen bündig in einer Ebene mit einer dem Stecker zugewandten Vorderseite der Buchse angeordnet sind, wobei sich die Kontaktelemente und die Gegenkontaktelemente mit ihren aufeinander ausgerichteten Kontaktflächen bzw. Gegenkontaktflächen flächig kontaktieren, wenn der Stecker magnetisch mit der Buchse verbunden ist.It is advantageous if the contact elements are inserted into the plug in such a way that their contact surfaces are arranged substantially in a plane with one of the jack facing the front of the plug and the mating contact elements are inserted in the socket so that the mating contact surfaces are substantially flush in a plane with a plug facing the front side of the socket are arranged, wherein contact the contact elements and the mating contact elements with their aligned contact surfaces or mating contact surfaces areal when the plug is magnetically connected to the socket.
Diese Ausgestaltung hat sich als besonders geeignet herausgestellt, insbesondere da die Magneteinrichtung eine zuverlässige Kontaktierung ermöglicht. Ein Verbinden des Steckers mit der Buchse und ein Wiederabnehmen ist in einfacher Weise möglich. Unter der Formulierung "im Wesentliche in einer Ebene" ist dabei auch zu verstehen, dass die Kontaktflächen und/oder die Gegenkontaktflächen leicht bzw. geringfügig über die Ebene der Vorderseite des Steckers oder der Buchse überstehen oder leicht bzw. geringfügig zurückversetzt bzw. versenkt sind. Es kann sich dabei insbesondere anbieten, wenn die Kontaktflächen in der Vorderseite des Steckers leicht zurückversetzt sind und die Gegenkontaktflächen leicht über die Vorderseite der Buchse hinausstehen, so dass die Gegenkontaktflächen jeweils in den Kontaktflächen zugeordneten Vertiefungen der Vorderseite des Steckers eindringen, wenn die Buchse mit dem Stecker verbunden wird. Eine derartige Vertiefung kann beispielsweise 1 bis 3 mm aufweisen. Dadurch kann eine verbesserte Verbindung zwischen den Kontaktflächen der Kontaktelemente und den Gegenkontaktflächen der Gegenkontaktelemente erreicht werden. Es wird dadurch eine mechanische Führung für die Gegenkontaktelemente realisiert. Gleichwohl wird dadurch keine mechanische Verbindung zwischen dem Stecker als Ganzes und der Buchse als Ganzes realisiert, die bei einer ungewollten Zug- oder Biegebelastung des Steckers beschädigt werden könnte.This embodiment has been found to be particularly suitable, in particular because the magnetic device allows reliable contact. A connection of the plug to the socket and a Wiederabnehmen is possible in a simple manner. The expression "substantially in one plane" also means that the contact surfaces and / or the mating contact surfaces project slightly or slightly beyond the plane of the front side of the plug or the socket or slightly set back or recessed are. It may be particularly suitable if the contact surfaces in the front of the plug are slightly set back and the mating contact surfaces slightly beyond the front of the socket so that the mating contact surfaces in each case in the contact surfaces associated recesses of the front of the plug penetrate when the socket with the Plug is connected. Such a depression may for example have 1 to 3 mm. As a result, an improved connection between the contact surfaces of the contact elements and the mating contact surfaces of the mating contact elements can be achieved. It is realized by a mechanical guide for the mating contact elements. However, this does not realize a mechanical connection between the plug as a whole and the socket as a whole, which could be damaged in an unwanted tensile or bending load of the plug.
Selbstverständlich kann auch vorgesehen sein, dass die Kontaktflächen der Kontaktelemente leicht über die Vorderseite des Steckers überstehen und entsprechend analog die Gegenkontaktflächen der Gegenkontaktelemente leicht in die Vorderseite der Buchse versenkt bzw. zurückversetzt sind. Beide Lösungen bieten sich gleichermaßen an.Of course, it can also be provided that the contact surfaces of the contact elements easily project beyond the front of the plug and, analogously, the countercontact surfaces of the mating contact elements are easily recessed or set back into the front side of the socket. Both solutions are equally suitable.
Von Vorteil kann es ferner sein, wenn der Stecker und die Buchse eine sogenannte mechanische Kodierung aufweisen, durch welche in bekannter Weise sichergestellt wird, dass der Stecker nur in einer Position auf die Buchse aufgesetzt bzw. mit dieser verbunden werden kann. Die mechanische Kodierung kann beispielsweise durch einen Vorsprung in der Buchse oder dem Stecker realisiert werden, welcher in einen entsprechenden Rücksprung des Steckers bzw. der Buchse eingreift.It may also be advantageous if the plug and the socket have a so-called mechanical coding, by which it is ensured in a known manner that the plug can only be placed in or connected to the socket in one position. The mechanical coding, for example, by a projection in the socket or the Plug can be realized, which engages in a corresponding recess of the plug or the socket.
Von Vorteil ist es, wenn die Magnete in der Buchse und/oder das nicht permanent-magnetische Verbindungsglied in dem Stecker durch Kleben, Klemmen oder Clipsen gehalten sind. Dadurch lässt sich der Magnet und/oder das nicht permanent-magnetische Verbindungsglied besonders einfach anordnen und montieren.It is advantageous if the magnets in the socket and / or the non-permanent-magnetic connecting member are held in the plug by gluing, clamping or clipping. As a result, the magnet and / or the non-permanent-magnetic connecting member can be arranged and mounted particularly easily.
Von Vorteil ist es, wenn die Buchse in einem elektronischen Bauteil oder einem elektronischen Gerät, insbesondere einem medizinischen Gerät, integriert ist.It is advantageous if the socket is integrated in an electronic component or an electronic device, in particular a medical device.
Von Vorteil ist es ferner, wenn der Stecker ein Kugelgelenk und/oder ein Drehgelenk und/oder ein Scharnier aufweist, über welches ein Kabelabgang beweglich mit einem Gehäuse des Steckers verbunden ist.It is also advantageous if the plug has a ball joint and / or a hinge and / or a hinge, via which a cable outlet is movably connected to a housing of the plug.
Aus dem allgemeinen Stand der Technik ist es bekannt, bei Steckern einen sogenannten Knickschutz vorzusehen, d. h. der Stecker weist im Bereich des Kabelabgangs einen Kabelknickschutz auf, durch den vermieden wird, dass Zug- oder Biegebelastungen, die auf das Kabel bzw. den Kabelabgang einwirken, so in das Innere des Kabels übertragen werden, dass dort Beschädigungen auftreten. Ein derartiger Kabelknickschutz kann beispielsweise durch mechanische Vorsprünge und/oder Rücksprünge im Steckergehäuse im Bereich des Kabelabgangs realisiert werden, welche mit entsprechend komplementär ausgebildeten Rücksprüngen und/oder Vorsprüngen im Bereich der Außenseite des Kabelabgangs korrespondieren, so dass eine vorzugsweise formschlüssige mechanische Verbindung zwischen dem Kabelabgang und einem den Kabelabgang umfassenden Bereich des Steckers hergestellt ist.From the general state of the art, it is known to provide a so-called kink protection in the case of plugs, ie the plug has cable kink protection in the region of the cable outlet, which avoids tensile or bending loads acting on the cable or the cable outlet. be transferred to the interior of the cable that there damage occur. Such Kabelknickschutz can be realized for example by mechanical projections and / or recesses in the connector housing in the region of the cable outlet, which correspond with correspondingly complementary recesses and / or projections in the region of the outside of the cable outlet, so that a preferably positive mechanical connection between the cable outlet and the cable outlet comprehensive area of the plug is made.
Die Erfinder haben in einer vorteilhaften Weiterentwicklung der vorliegenden Erfindung erkannt, dass ein ungewolltes Lösen des Steckers von der Buchse dadurch reduziert werden kann, dass der Stecker ein Kugelgelenk und/oder eine Drehgelenk und/oder ein Scharnier aufweist, über welches der Kabelabgang beweglich mit dem Gehäuse des Steckers verbunden ist. Dies führt dazu, dass bei einer Zug- oder Biegebelastung auf das Kabel bzw. den Kabelabgang zunächst das Kugelgelenk und/oder das Drehgelenk und/oder das Scharnier bewegt wird. Dadurch wird zunächst keine Kraft auf den Stecker bzw. die Verbindung zwischen dem Stecker und der Buchse übertragen. Erst wenn das Kugelgelenk, das Drehgelenk oder das Scharnier einen Endanschlag erreicht haben bzw. sich nicht weiter drehen/bewegen können, erfolgt eine Übertragung der Zug- oder Biegebelastung des Kabels bzw. Kabelabgangs auf den Stecker bzw. die Verbindung zwischen dem Stecker und der Buchse. Es lassen sich durch die Ausbildung eines Kugelgelenks und/oder eines Drehgelenks und/oder eines Scharniers auftretende Kräfte zumindest teilweise aufnehmen, so dass die Gefahr eines ungewollten Lösens des Steckers reduziert wird.The inventors have recognized in an advantageous development of the present invention that an unintentional release of the plug from the socket can be reduced in that the plug has a ball joint and / or a hinge and / or a hinge, via which the cable outlet movable with the Housing of the plug is connected. As a result, in the case of a tensile or bending load on the cable or the cable outlet, first the ball joint and / or the rotary joint and / or the hinge is moved. As a result, initially no force is transmitted to the plug or the connection between the plug and the socket. Only when the ball joint, the hinge or the hinge have reached an end stop or can not continue to rotate / move, there is a transmission of tensile or bending load of the cable or cable outlet on the plug or the connection between the plug and the socket , It can be absorbed by the formation of a ball joint and / or a hinge and / or a hinge forces occurring at least partially, so that the risk of unwanted loosening of the plug is reduced.
Durch diese Ausgestaltung wird somit bewirkt, dass sich zunächst das Kabel gegenüber dem Stecker bewegen kann, bevor die Zug- oder Biegebelastung auf die magnetische Verbindung einwirkt. Im Unterschied dazu überträgt sich eine Biege- oder Zugbelastung, die auf einen Kabelabgang oder ein Kabel wirkt, sofort auf die magnetische Verbindung, wenn lediglich eine Knickschutzhülle vorgesehen ist, d. h. eine feste mechanische Verbindung zwischen dem Kabelabgang und dem Stecker.As a result of this configuration, the cable is initially able to move relative to the plug before the tensile or bending load acts on the magnetic connection. In contrast, a bending or tensile load acting on a cable outlet or cable translates immediately to the magnetic connection, if only one Anti-kink sleeve is provided, ie a fixed mechanical connection between the cable outlet and the plug.
Erfindungsgemäß kann auch vorgesehen sein, Stecker für ein elektrisches Verbindungssystem nach einem der Ansprüche 1 bis 4 als Ersatz- oder Zubehörteil einzusetzen. Dabei ist es ebenfalls von Vorteil, wenn der Stecker ein Kugelgelenk und/oder ein Drehgelenk und/oder ein Scharnier aufweist, welches einen Kabelabgang beweglich mit einem Gehäuse des Steckers verbindet.According to the invention can also be provided to use plug for an electrical connection system according to one of
Von Vorteil ist es, wenn ein elektronisches Bauteil oder elektronisches Gerät, insbesondere für medizinische Anwendungen, mit einer Buchse als Teil eines elektrischen Verbindungssystems nach einem der Ansprüche 1 bis 4 ausgestattet ist. Die Buchse kann dabei in bekannter Weise in das Gerät integriert sein. Erfindungsgemäß kann dabei auch vorgesehen sein, dass das elektronische Bauteil oder elektronische Gerät mit mehreren erfindungsgemäßen Buchsen versehen ist.It is advantageous if an electronic component or electronic device, in particular for medical applications, is equipped with a socket as part of an electrical connection system according to one of
Die Verwendung eines elektrischen Verbindungssystems zum Verbinden eines Steckers mit einer Buchse eignet sich besonders für elektronische, medizinische Bauteile oder elektronische, medizinische Geräte, die in medizinischen Versorgungseinrichtungen, insbesondere in Krankenhäusern, zum Einsatz kommen. Hierauf ist die Erfindung jedoch nicht beschränkt. Es sind auch andere Bereiche, die sensibel auf Magnetfelder reagieren, bekannt, bei denen der Einsatz des erfindungsgemäßen elektrischen Verbindungssystems von Vorteil sein kann, beispielsweise in Flugzeugen oder in der Raumfahrt.The use of an electrical connection system for connecting a plug to a socket is particularly suitable for electronic, medical, or electronic medical devices used in medical care facilities, particularly in hospitals. However, the invention is not limited thereto. There are also other areas that are sensitive to magnetic fields, known, in which the use of the electrical connection system according to the invention can be of advantage, for example in aircraft or in space travel.
