Abstract

A shielded magnetic plug-in lock, for which a connector is plugged into a connector receiving element and held therein by magnetic holding forces or additionally by means of mechanical engagement, is provided. The connector and the connector receiving element are designed in such a way that the connector magnet and the magnet for the connector receiving element are magnetized transversely to the closing direction X, and at least one shielding plate consisting of a ferro-magnetic material is provided on the plug or the plug receiving element. The shielding plate covers the connector magnet and the connector receiving element magnets, and the ferro-magnetic material and the thickness of the shielding plate are selected in such a way as to obtain a magnetic shielding sufficient for a pre-determined use.

Description

Die Erfindung betrifft einen abgeschirmten Magnetverschluss, der magnetisch empfindliche Instrumente oder Gegenstände, wie z. B. Kreditkarten, Herzschrittmacher, Magnet-Datenspeicher oder Tonbänder nicht beschädigt oder ungewünscht beeinflusst und insbesondere einen Magnetsteckverschluss, bei welchem ein Stecker in eine Steckeraufnahme gesteckt wird und darin durch Magnethaltekräfte oder zusätzlich mittels mechanischer Verrastung gehalten wird.The invention relates to a shielded magnetic closure, the magnetically sensitive instruments or objects, such. As credit cards, pacemakers, magnetic data storage or tapes are not damaged or affected undesirable and in particular a magnetic plug in which a plug is plugged into a connector receptacle and is held by magnetic holding forces or additionally by means of mechanical latching.

Eine spezielle Gruppe derartiger Verschlüsse zeichnet sich dadurch aus, dass zum Schließen die beiden Verschlusshälften in einer Schließrichtung zusammengesteckt werden, wobei sich die in den Verschlusshälften angeordneten Magnete gegenseitig anziehen, zum Öffnen aber die beiden Verschlusshälften nicht ruckartig entgegengesetzt zur Schließrichtung wieder auseinandergezogen werden, sondern allmählich seitlich voneinander in einer Öffnungsrichtung abgeschoben werden. Damit wird eine angenehme Haptik erzielt, wobei unter Haptik verstanden wird, wie sich der Verschluss beim Öffnen und beim Schließen für die Person, die den Verschluss betätigt, anfühlt. Diese Eigenschaft ist ein wesentliches Kriterium dafür, ob ein von Hand zu bedienender Verschluss für die Praxis tauglich ist, d. h., ein Verschluss muss sich haptisch angenehm schließen und öffnen lassen.A special group of such closures is characterized in that, for closing, the two closure halves are plugged together in a closing direction, wherein the magnets arranged in the closure halves attract each other, but for opening the two closure halves are not pulled apart jerkily opposite to the closing direction, but gradually be laterally pushed away from each other in an opening direction. This results in a pleasant feel, whereby the feel is understood to mean how the closure feels during opening and closing for the person who actuates the closure. This property is an essential criterion for whether a hand-operated closure is fit for practice, d. h., a closure must be pleasant to close and open.

Um die Probleme der Abschirmung eines Magnetverschlusses anschaulicher darstellen zu können, sind in den Fig. 4a, 4b lediglich die Magnete eines solchen Verschlusses gezeigt, d. h. das Gehäuse für den Stecker und das Gehäuse für die Steckeraufnahme sind nicht gezeichnet. Die Fig. 4a zeigt, dass sich Nord und Südpol gegenüberliegen, sodass eine maximale Anziehung gewährleistet ist. Um den Verlauf der Magnetfeldlinien besser zeigen zu können, ist der Verschluss nicht vollständig geschlossen, d. h. die Magnete sind noch voneinander geringfügig beabstandet. Es ist dargestellt, dass ein Teil der Magnetfeldlinien kreisbogenförmig außerhalb der Magnete verlaufen. Dieser Teil des Magnetfeldes ist auf den Außenseiten des Steckverschlusses, das heißt außerhalb, wirksam und könnte den magnetfeldempfindlichen Teil einer direkt darauf gelegten Kreditkarte beschädigen. Daher muss verhindert werden, dass dieser Teil der Magnetfeldlinien austritt.In order to illustrate the problems of shielding a magnetic closure can be seen in the Fig. 4a, 4b only the magnets of such a closure shown, ie the housing for the plug and the housing for the plug receptacle are not drawn. The Fig. 4a shows that the north and south poles face each other so that maximum attraction is guaranteed. In order to better show the course of the magnetic field lines, the shutter is not completely closed, that is, the magnets are still slightly spaced from each other. It is shown that part of the magnetic field lines extend in a circular arc outside the magnets. This portion of the magnetic field is effective on the outsides of the male fastener, that is, outside, and could damage the magnetic field sensitive portion of a credit card placed directly thereon. Therefore, it must be prevented that this part of the magnetic field lines emerges.

Beim Öffnen des Verschlusses werden die Verschlusshälften zueinander so bewegt, dass die Magnete voneinander abgeschoben werden, siehe Fig. 4b. Weitere Erläuterungen dazu erfolgen in der Beschreibung der Ausführungsformen der Erfindung.When opening the shutter, the shutter halves are moved towards each other so that the magnets are pushed apart from each other, see Fig. 4b , Further explanations will be given in the description of the embodiments of the invention.

Um das Austreten von Magnetfeldlinien, wie in Fig. 4a gezeigt, zu verhindern, können Magnetleitbleche eingesetzt werden. Diese Magnetleitbleche und deren Wirkung sind in Fig. 5 gezeigt und aus dem Stand der Technik bereits bekannt. Wie aus den Figuren 5a und 5b ersichtlich ist, treten weder im geschlossenen Zustand des Verschlusses, noch bei geöffnetem Verschluss nahezu keine Magnetfelder auf den Außenseiten des Verschlusses aus, was für diesen Verschluss wünschenswert wäre. Trotzdem ist diese Art der Abschirmung für Verschlüsse nach Fig. 4 nicht anwendbar. Das hat folgenden Grund:To prevent the leakage of magnetic field lines, as in Fig. 4a can be used to prevent magnetic guide plates can be used. These Magnetleitbleche and their effect are in Fig. 5 shown and already known from the prior art. Like from the FIGS. 5a and 5b it can be seen, occur neither in the closed state of the closure, or open shutter almost no magnetic fields on the outer sides of the closure, which would be desirable for this closure. Nevertheless, this type of shielding for closures is after Fig. 4 not applicable. This has the following reason:

Die Magnetanordnungen nach Fig. 4 verfügen über die Eigenschaft, sich bei einer seitlichen Verschiebung zueinander selbsttätig zurückzustellen. Diese Eigenschaft ist aus dem Stand der Technik bekannt und wird bei einigen Arten von Magnetverschlüssen eingesetzt, um z. B. die Öffnungshaptik zu verbessern. Das soll anhand der Fig. 4b beschrieben werden: Die Pfeile zwischen den zueinander versetzt liegenden Magnetflächen symbolisieren die Rückstellkäfte. Die Pfeile können auch als gedehnte Gummibänder aufgefasst werden, die versuchen, den verschobenen Magneten 2 wieder über den Magneten 1 zurück zuziehen. So wird verständlich, dass beim Öffnen eines solchen Magnetverschlusses eine sanft ansteigende Kraft überwunden werden muss, wodurch eine für die menschliche Hand angenehme Haptik entsteht. Die in Fig. 5 gezeigte Anordnung weist jedoch diese Rückstellkraft nicht auf. Insofern ist einerseits eine Anordnung nach Fig. 5 für vorstehend beschriebene Magnetsteckverschlüsse hinsichtlich ihrer geringen magnetischen Streuwirkung sehr gut geeignet, andererseits ist diese Anordnung wegen der fehlenden Rückstellkraft nicht geeignet. Insofern musste nach weiteren Möglichkeiten zur magnetischen Abschirmung gesucht werden. Eine firmenintern entwickelte, nicht veröffentlichte Lösung ist in den Fig. 3a, 3b gezeigt. Es wird eine Magnetanordnung nach Fig. 4 verwendet. Ein Magnet ist in dem Stecker und der zweite Magnet ist in der Steckeraufnahme angeordnet. Der Stecker wird in der Schließrichtung X in die Steckeraufnahme gesteckt, wobei sich der Südpol des Stecker-Magneten und der Nordpol des Steckeraufnahme-Magneten anziehend gegenüberliegen. Zum Öffnen wird der Stecker seitlich aus der Steckeraufnahme herausgeschoben, sodass sich die Magnete gegeneinander verschieben.The magnet arrangements after Fig. 4 have the property to reset themselves automatically when they shift laterally. This feature is well known in the art and is used in some types of magnetic closures, e.g. B. to improve the opening feel. That should be based on the Fig. 4b are described: The arrows between the mutually offset magnetic surfaces symbolize the Rückstellkäfte. The arrows can also be understood as stretched rubber bands that try to pull the shifted magnet 2 back over the magnet 1. So it is understandable that when opening such a magnetic closure, a gently increasing force must be overcome, creating a pleasant for the human hand feel. In the Fig. 5 However, the arrangement shown does not have this restoring force. In this respect, on the one hand, an arrangement according to Fig. 5 for magnetic tabs described above very well suited for their low magnetic scattering effect, on the other hand, this arrangement is not suitable because of the lack of restoring force. In this respect, further possibilities for magnetic shielding had to be sought. An in-house developed, unpublished solution is in the Fig. 3a, 3b shown. It will after a magnet arrangement Fig. 4 used. A magnet is in the plug and the second magnet is located in the plug receptacle. The plug is inserted in the closing direction X in the connector receptacle, wherein the south pole of the plug magnet and the north pole of the plug-receiving magnet are attractively opposed. To open, the plug is pushed laterally out of the connector receptacle, so that the magnets move against each other.

Zur Vermeidung der in Fig. 4a gezeigten, nach außen wirkenden Magnetfeldlinien, wurden in der Steckeraufnahme Abschirmbleche 5, 5' angeordnet. Dieses Mittel hat sich als geeignet erwiesen, die magnetischen Streulinien nach außen ausreichend abzuschirmen. Bei dieser Konstruktion trat jedoch ein neuer Effekt auf, der beim Einstecken des Steckers die Haptik stark verschlechterte. Der Stecker ließ sich nicht mehr leicht einstecken, sondern blieb am oberen Rand der Steckeraufnahme hängen, was durch eine magnetische Anziehung bewirkt wurde. Das hat folgende Ursache: Entlang den seitlichen Oberkanten der Steckeraufnahme verlaufen auch die Oberkanten der Abschirmbleche. Die Oberkanten der beiden Abschirmbleche 5, 5' sind magnetisch gleichnamig gepolt, da sie beide im Streufeld des Nordpols des Steckeraufnahmemagneten liegen. Daher sind im vorliegenden Beispiel nach Fig. 3 beide Oberkanten N-polig. Wird nun versucht, den Stecker von Hand in die Steckeraufnahme zu stecken, wird der Stecker entweder an den linken oder an den rechten Seitenrand der Steckeraufnahme gezogen, weil im Steckermagnet der Südpol vorn liegt und sich ungleichnamige Pole anziehen.To avoid the in Fig. 4a shown, outwardly acting magnetic field lines, shielding plates 5, 5 'were arranged in the connector receptacle. This agent has proved to be suitable for shielding the magnetic scattering lines to the outside sufficiently. In this construction, however, a new effect occurred, which greatly reduced the feel when plugging in the plug. The plug was no longer easy to plug in, but stuck to the top of the plug receptacle, which was caused by a magnetic attraction. This has the following reason: along the lateral upper edges of the connector receptacle extend the upper edges of the shielding plates. The upper edges of the two shielding plates 5, 5 'are poled magnetically the same name, since they are both in the stray field of the north pole of the plug-receiving magnet. Therefore are in the present example Fig. 3 both upper edges N-pole. If an attempt is now made to insert the plug into the plug receptacle by hand, the plug is pulled either to the left or to the right side edge of the plug receptacle, because in the plug magnet the south pole is at the front and unlike poles are tightened.

Insofern muss sich die Bedienperson stark konzentrieren und auch eine gewisse Kraft aufbringen, um den Stecker zwischen diese magnetischen N-Pole in die Einstecköffnung zu stecken, was als sehr schlechte Haptik empfunden wird.In this respect, the operator must concentrate heavily and also apply a certain amount of force to plug the connector between these magnetic N poles in the insertion, which is perceived as a very bad feel.

Bei einem aus der WO 2008/006354 A2 bekannten Magnetverschluss sind zwei Verbindungsmodule zum Verbinden von zwei Elementen vorgesehen, an denen jeweils eines der Verbindungsmodule befestigbar ist. Jedes der Verbindungsmodule weist wenigstens einen Permanentmagneten auf. An jedem Verbindungsmodul ist ein rohrförmiger oder rinnenförmiger Führungsabschnitt angeordnet, dessen Querschnitt beliebig geformt sein kann. Die Führungsabschnitte sind ineinander steckbar ausgebildet und tragen die Permanentmagnete, wobei in einem ersten Führungsabschnitt ein Permanentmagnet fest und in einem zweiten Führungsabschnitt ein Permanentmagnet so bewegbar angeordnet ist, dass sich der Permanentmagnet beim Schließen selbsttätig in eine Anzugsposition zu dem anderen Permanentmagnet ausrichtet.At one of the WO 2008/006354 A2 known magnetic closure two connection modules for connecting two elements are provided, to each of which one of the connection modules can be fastened. Each of the connection modules has at least one permanent magnet. At each connection module, a tubular or channel-shaped guide section is arranged, whose cross section can be arbitrarily shaped. The guide sections are designed to be plugged into one another and carry the permanent magnets, a permanent magnet being fixed in a first guide section and a permanent magnet being movably arranged in a second guide section such that the permanent magnet automatically aligns with a closing position to the other permanent magnet.

Eine aus der WO 2009/103279 A2 bekannte mechanisch-magnetische Verbindungskonstruktion weist zwei Verbindungsmodule auf, die über eine Verriegelungsvorrichtung zum formschlüssigen Verriegeln und eine Magnet-Anker-Konstruktion mechanisch und magnetisch miteinander verbindbar sind. Am ersten Verbindungsmodul ist eine Verschiebebahn ausgebildet, auf der ein Sperrstück des einen Verbindungsmoduls von einer Schließposition, d. h. einem Verriegelungszustand, in eine Offenposition, d. h. in einen entriegelten Zustand, verschiebbar ist. Beim Öffnen werden die Verbindungsmodule von der Schließposition in die Offenposition auf der Verschiebebahn verschoben, wobei eine magnetische Anziehungskraft der Magnet-Anker-Konstruktion allmählich abgeschwächt und gleichzeitig die Verriegelungsvorrichtung gelöst wird.One from the WO 2009/103279 A2 known mechanical-magnetic connection structure has two connection modules, which are mechanically and magnetically connected to each other via a locking device for positive locking and a magnet-armature construction. At the first connection module, a displacement track is formed, on which a locking piece of the one connection module is displaceable from a closed position, ie a locking state, into an open position, ie into an unlocked state. When opening the connection modules are moved from the closed position to the open position on the sliding track, whereby a magnetic attraction of the magnetic armature construction is gradually attenuated and at the same time the locking device is released.

Bei einem aus der WO 2009/006888 A2 bekannten Magnetverschluss sind ein Magnet und ein Anker so ausgebildet, dass sich zum selbsttätigen Schließen des Magnetverschlusses der Anker und der Magnet gegenseitig anziehen. Zum Öffnen des Magnetverschlusses kann der Magnet gegenüber dem Anker seitlich verschoben oder verdreht werden, wobei der Anker vom Magnet seitlich abgeschoben wird und dadurch auch die Anziehungskraft zwischen Magnet und Anker geringer wird. zur Unterstützung dieses Öffnungsvorgangs ist eine Öffnungsunterstützungsfeder vorgesehen.At one of the WO 2009/006888 A2 known magnetic closure, a magnet and an armature are designed so that attract each other for automatically closing the magnetic closure of the armature and the magnet. To open the magnetic closure of the magnet relative to the anchor can be moved laterally or rotated, the armature is laterally deported from the magnet and thus the attraction between magnet and armature becomes smaller. to assist this opening operation, an opening assist spring is provided.

Es ist demzufolge die Aufgabe der Erfindung, einen Magnetsteckverschluss der eingangs beschriebenen Bauart bereitzustellen, der sowohl eine gute magnetische Abschirmung aufweist, als auch eine gute Haptik 15 beim Schließen und beim Öffnen hat.It is therefore the object of the invention to provide a magnetic plug of the type described above, which has both a good magnetic shielding, as well as a good feel 15 when closing and opening.

Diese Aufgabe wird mit einem Magnetsteckverschluss nach Anspruch 1 gelöst, wobei der Magnetsteckverschluss einen Stecker und eine Steckeraufnahme aufweist. In dem Stecker ist ein Steckermagnet und in der Steckeraufnahme ist ein Steckeraufnahmemagnet angeordnet. Der Stecker und die Steckeraufnahme sind so ausgebildet, dass zum Schließen des Magnetsteckverschlusses der Stecker stirnseitig in die Steckeraufnahme steckbar ist. Die Richtung, in welche der Stecker beim Einstecken bewegt wird, ist die Schließrichtung X. Zum Öffnen des Magnetsteckverschlusses wird der Stecker seitlich zu dieser Schließrichtung X aus der Steckeraufnahme herausgeschoben, d. h. die Öffnungsrichtung ist nicht entgegengesetzt zur Schließrichtung X.This object is achieved with a magnetic plug closure according to claim 1, wherein the magnetic plug closure has a plug and a plug receptacle. In the plug is a plug magnet and in the plug receptacle a plug-receiving magnet is arranged. The plug and the plug receptacle are designed so that the plug can be plugged into the plug receptacle for closing the magnetic plug closure. The direction in which the plug is moved when inserting, is the closing direction X. To open the magnetic plug closure, the plug is pushed laterally to this closing direction X from the plug receptacle, d. H. the opening direction is not opposite to the closing direction X.

Erfindungsgemäß sind der Steckermagnet und der Steckeraufnahmemagnet quer zur Schließrichtung X des Magnetsteckverschlusses magnetisiert. Weiterhin sind der Steckermagnet und der Steckeraufnahmemagnet bezogen auf die Schließrichtung X folgendermaßen positioniert: Im Steckermagnet liegt der Nordpol links und der Südpol rechts. Beim Steckeraufnahmemagnet liegen die Pole vertauscht, sodass sich Stecker und Steckeraufnahme gegenseitig anziehen. Mit anderen Worten, der Steckermagnet und der Steckeraufnahmemagnet liegen sich gegensätzlich polarisiert gegenüber.According to the invention, the plug magnet and the plug-receiving magnet are magnetized transversely to the closing direction X of the magnetic plug closure. Furthermore, the plug magnet and the plug-receiving magnet are positioned as follows with respect to the closing direction X: In the plug magnet, the north pole is on the left and the south pole on the right. At the plug receiving magnet the poles are reversed, so that plug and plug receptacle attract each other. In other words, the plug magnet and the plug receptacle magnet are oppositely polarized.

Es ist für den Fachmann klar, dass durch diese Merkmalskombination eine geringere magnetische Anzugskraft bewirkt wird, als wenn jede der sich gegenüber liegenden Magnetflächen nur je einen Magnetpol aufweist, d. h. die Magnete längs zur Schließrichtung X polarisiert sind und somit die Anzugskraft höher ist.It is clear to those skilled in the art that this combination of features causes a lower magnetic attraction force than if each of the opposing magnetic surfaces only ever has one magnetic pole, d. H. the magnets are polarized longitudinally to the closing direction X and thus the tightening force is higher.

Es soll hervorgehoben werden, dass es für den Fachmann, der einen Magnetsteckverschluss konstruiert, daher keinen Grund gibt, diese Magnetisierungsrichtung zu wählen, weil ihm der Nachteil dieser Anordnung bekannt ist.It should be emphasized that there is no reason for those skilled in the art constructing a magnetic plug-in closure to choose this direction of magnetization because they are aware of the disadvantage of this arrangement.

Zur Erfindung gehören weiterhin ein oder mehrere Abschirmbleche aus ferromagnetischem Material. Diese Abschirmbleche überdecken sowohl den Steckermagneten und als auch den Steckeraufnahmemagneten so weit, dass eine für den jeweiligen Einsatzzweck genügende Abschirmung gewährleistet ist. Dem Fachmann ist klar, dass die Eigenschaften des ferromagnetischen Materials selbst und deren Dicke die Abschirmeigenschaften der Abschirmbleche beeinflussen, sodass der Fachmann bei der Bestimmung der erforderlichen Größe des Abschirmbleches auch das Material und die Dicke berücksichtigt. Insofern ist es auch nicht möglich genau anzugeben, wie groß das Abschirmblech ausgebildet sein muss.The invention further includes one or more shielding plates of ferromagnetic material. These shielding plates cover both the plug magnet and the plug-receiving magnet so far that a sufficient for the particular application shield is guaranteed. It will be understood by those skilled in the art that the properties of the ferromagnetic material itself and its thickness will affect the shielding properties of the shielding plates so that those skilled in the art will also be aware of the material and thickness in determining the required size of the shielding plate. In this respect, it is also not possible to specify exactly how large the shielding plate must be formed.

Diese Anordnung weist gegenüber dem vorstehend beschriebenen Stand der Technik eine für den Bediener des Magnetsteckverschlusses sehr angenehme haptische Eigenschaft auf: Wenn der Stecker von Hand in X-Richtung in die Nähe des Einzugsbereiches geführt wird, bleibt er nicht mehr an der Oberkante der Steckeraufnahme hängen, sondern wird durch eine magnetische Selbstzentrierung in die optimale Einsteckposition zentriert. Dieser Effekt wird nachfolgend erklärt:This arrangement has over the prior art described above, a very pleasant for the operator of the magnetic plug closure haptic property: When the plug is manually guided in the X direction in the vicinity of the catchment area, it does not hang on the top of the connector receptacle but is going through centered a magnetic self-centering in the optimal insertion position. This effect is explained below:

Die Abschirmbleche werden durch den Steckeraufnahmemagneten magnetisch polarisiert. Da der Steckeraufnahmemagnet quer zur Schließrichtung polarisiert ist, sind die Oberkanten der Abschirmbleche ungleichnamig polarisiert. Dadurch erhält der Stecker die vorstehend erwähnte Tendenz zur Selbstzentrierung, wenn er in die Nähe des Einsteckbereichs der Steckeraufnahme gelangt. Im Ausführungsbeispiel werden die magnetischen Kräfteverhältnisse noch näher erläutert.The shielding plates are magnetically polarized by the plug-receiving magnet. Since the plug-receiving magnet is polarized transversely to the closing direction, the upper edges of the shielding plates are polarized unlike. As a result, the plug obtains the above-mentioned tendency for self-centering when it comes close to the insertion area of the plug receptacle. In the embodiment, the magnetic balance of power will be explained in more detail.

Vorstehend wurde nur die Version mit zwei Abschirmblechen beschrieben. Die technische Lehre des angenehmen, selbstzentrierenden Schließens ohne versehentliches Anhaften des Steckers an der Oberkante des Abschirmblechs funktioniert aber auch mit nur einem Abschirmblech auf einer Seite des Verschlusses.Above, only the version with two shielding plates has been described. However, the technical teaching of the pleasant, self-centering closing without accidental sticking of the plug to the upper edge of the shielding plate also works with only one shielding plate on one side of the closure.

Somit ist festzustellen, dass die bei der Konstruktion nach Fig. 3 beschriebenen Probleme bei der Erfindung nicht auftreten. Insofern weist der erfindungsgemäße Verschluss eine deutlich verbesserte Schließhaptik bei gleichzeitig guter Abschirmung des Magnetfeldes auf.Thus, it should be noted that in the construction after Fig. 3 Problems described in the invention do not occur. In this respect, the closure according to the invention has a significantly improved closing feel with at the same time good shielding of the magnetic field.

Nach Anspruch 2 ist die Erfindung so weitergebildet, dass beim Schließen in Schließrichtung X eine Federverrastirng zwischen Stecker und Steckeraufnahme durch die magnetische Anziehung geschlossen wird. Der Verschluss hält dann magnetisch und mechanisch zu. Zum Öffnen wird der Stecker seitlich zur Schließrichtung X verschoben, wobei die Federverrastung seitlich außer Eingriff verschoben wird, ohne dass die Rastfedern zum Öffnen durch eine Kraft aufgespreizt werden müssen. Durch die zusätzliche Anordnung der mechanischen Verrastung entsteht ein Verschluss mit einer stabilen mechanischen Verriegelung, wobei die weiche Haptik erhalten bleibt.According to claim 2, the invention is further developed so that when closing in the closing direction X a Federverrastirng between plug and plug receptacle is closed by the magnetic attraction. The shutter then holds magnetically and mechanically closed. To open the plug is moved laterally to the closing direction X, wherein the spring latch is displaced laterally out of engagement, without the locking springs must be spread to open by a force. The additional arrangement of the mechanical locking creates a closure with a stable mechanical locking, while maintaining the soft feel.

Während bei der vorstehend beschriebenen Weiterbildung die Federn der Federverrastung beim Öffnen nicht aufgespreizt werden, werden bei einer sehr ähnlichen Weiterbildung der Erfindung die Federn aufgespreizt. Dazu wird eine kraftumlenkende Schräge eingesetzt, die beim Öffnen durch Verschiebung seitlich zur Schließrichtung X die Federverrastung während der Verschiebung durch Aufspreizen der Federn allmählich öffnet.While in the development described above, the springs of Federverrastung are not spread when opening, the springs are spread in a very similar development of the invention. For this purpose, a kraftumlenkende bevel is used, which opens when opening by shifting laterally to the closing direction X, the spring latch during the displacement by spreading the springs gradually.

Diese Ausführungsform bedarf eines höheren Kraftaufwands beim Öffnen, da sowohl die Magnete zueinander abgeschert werden müssen und zusätzlich die Rastfeder aufgespreizt werden muss. Dieser Eigenschaft kann aber bei Verschlüssen, die sich nicht versehentlich öffnen dürfen, vorteilhaft sein.This embodiment requires a higher force during opening, since both the magnets must be sheared to each other and in addition the detent spring must be spread. However, this feature can be beneficial for closures that are not allowed to open accidentally.

Nach Anspruch 3 sind zwei seitliche Abschirmbleche zu einem einstückigen Blech verbunden. Damit kann die Magnetfeldstreuung weiter vermindert werden, und es wird die Montage des Abschirmbleches erleichtert. Dies ist in einem Ausführungsbeispiel nach Fig. 6a, 6b gezeigt. Dieses Ausführungsbeispiel unterscheidet sich von dem in Fig 1a, 1b gezeigtem nur dadurch, dass die Abschirmbleche 5, 5' zu einem einzigen, U-förmigen Abschirmblech 5 zusammengefügt sind.According to claim 3, two lateral shielding plates are connected to a one-piece sheet metal. Thus, the magnetic field scattering can be further reduced and the mounting of the shielding plate is facilitated. This is according to an embodiment Fig. 6a, 6b shown. This embodiment differs from that in FIG Fig 1a, 1b shown only in that the shielding plates 5, 5 'are assembled into a single, U-shaped shielding plate 5.

Nach Anspruch 4 ist ebenfalls zusätzlich eine mechanische Federrastverriegelung vorgesehen, bei welcher der Stecker beim Zusammenstecken eine Federrastung beiseite drückt, bis der Stecker einrastet. Die Weiterbildung der Erfindung besteht darin, dass wenigstens ein Abschnitt eines Abschirmblechs als Feder ausgebildet ist. Diese Ausführungsform der Erfindung ist besonders vorteilhaft, da das Abschirmblech gleichzeitig die Funktion der Feder übernimmt. Insofern hat dieses Bauteil eine Doppelfunktion.According to claim 4, a mechanical spring detent lock is also provided in addition, in which the plug pushes a spring catch aside when pushed together until the plug engages. The development of the invention is that at least a portion of a shielding plate is designed as a spring. This embodiment of the invention is particularly advantageous, since the shield simultaneously assumes the function of the spring. In this respect, this component has a double function.

Die Fig. 1a zeigt den erfindungsgemäßen Magnetsteckverschluss in der Vorderansicht und Fig. 1b zeigt eine Schnittansicht B-B. Mit 1 und 2 sind stabförmige Magnete bezeichnet, die sich über die Breite des in Fig. 1a gezeigten Magnetsteckverschlusses erstrecken und in diesem Beispiel einen quadratischen Querschnitt aufweisen. Mit N für Nordpol und S für Südpol ist die Magnetisierung bezeichnet. Die Magnetisierung verläuft quer zur Schließrichtung X, in der der Stecker 3 in die Steckeraufnahme 4 gesteckt wird und dabei die Federverrastung aus den Rastnasen 8a, 8b und den federnden Federrastnasen 6a, 6b einrastet. Die Fig. 2a, b zeigt den zusammengesteckten Zustand, bei dem der Stecker 3 in der Steckeraufnahme 4 eingesteckt ist, wobei die Magnete 1, 2 gegensätzlich polarisiert anziehend beieinander liegen.The Fig. 1a shows the magnetic plug closure according to the invention in front view and Fig. 1b shows a sectional view BB. With 1 and 2 rod-shaped magnets are designated, which extend across the width of the in Fig. 1a shown Magnetsteckverschlusses and in this example have a square cross-section. With N for North Pole and S for South Pole magnetization is designated. The magnetization runs transversely to the closing direction X, in which the plug 3 is inserted into the plug receptacle 4 and thereby the spring latching of the latching lugs 8a, 8b and the resilient spring latching noses 6a, 6b engages. The Fig. 2a, b shows the mated state in which the plug 3 is inserted in the connector receptacle 4, wherein the magnets 1, 2 oppositely polarized attractively lie together.

Das mit der Erfindung gelöste Problem soll zuerst anhand eines firmeninternen, nicht zur Erfindung gehörenden Vergleichsbeispiels nach Fig. 3a, b erläutert werden. Dieser Magnetsteckverschluss ist bis auf einen Unterschied identisch mit der Erfindung. Die Magnetisierung der Magnete ist hier nicht quer, sondern längs zur Schließrichtung, d. h., der im Stecker 3 vom liegende Südpol des Steckermagnets 1 trifft beim Zusammenstecken auf den in der Steckeraufnahme 4 vorn liegenden Nordpol des Steckeraufnahmemagnets 2. An jeder Seite der Steckeraufnahme 4 ist ein 1 mm dickes Abschirmblech 5, 5' aus ferromagnetischem Material, in dem Beispiel Eisen, das eine gute magnetische Leitfähigkeit aufweist, angeordnet. Aufgrund der magnetischen Wechselwirkung mit dem Steckeraufnahmemagnet 2 sind die Oberkanten 5a, 5b der Abschirmbleche jeweils als Nordpol polarisiert. Wenn versucht wird, den Stecker 3 in die Steckeraufnahme 4 einzustecken, nähert sich der Südpol des Steckers den nordpolig magnetisierten Oberkanten 5a, 5b der Abschirmbleche 5. Je nach dem, von welcher Seite die Annäherung erfolgt, bleibt der Stecker an dieser Seite hängen. In Fig. 3b wird der Stecker gemäß der Pfeilrichtung an die linke Oberkante der Steckeraufnahme gezogen. Die Person, die den Verschluss bedient, muss den Stecker ruckartig wieder abreißen und erneut versuchen, den Stecker zentrisch einzuführen. Diese mangelhafte Haptik ist bei der Erfindung beseitigt, was anhand der Fig. 1b erläutert wird. Aufgrund der magnetischen Wechselwirkung mit dem Steckeraufnahmemagnet sind die Oberkanten 5a, 5b der Abschirmbleche 5 unterschiedlich polarisiert. Anhand der eingezeichneten Pfeile, die Anziehung und Absto-βung symbolisieren, ist erkennbar, dass die Magnetkräfte der Oberkanten der Abschirmbleche und des Steckeraufnahmemagnets auf den Stecker eine selbstzentrierende Wirkung ausüben.The problem solved by the invention is first based on a company-internal, not belonging to the invention according to comparative example Fig. 3a , b be explained. This magnetic plug is identical to the invention except for one difference. The magnetization of the magnets here is not transverse, but longitudinal to the closing direction, ie, in the plug 3 from the lying south pole of the plug magnet 1 strikes when mating on the front in the connector receptacle 4 north pole of the connector receptacle magnet 2. On each side of the connector receptacle 4 is a 1 mm thick shielding plate 5, 5 'of ferromagnetic material, in the example iron, which has a good magnetic conductivity, arranged. Due to the magnetic interaction with the plug-receiving magnet 2, the upper edges 5a, 5b of the shielding plates are each polarized as a north pole. If it is attempted to insert the plug 3 into the plug receptacle 4, the south pole of the plug approaches the north pole magnetized upper edges 5a, 5b of the shielding plates 5. Depending on which side the approach takes place, the plug will stick to this side. In Fig. 3b the plug is pulled according to the direction of the arrow to the left upper edge of the plug receptacle. The person operating the shutter must jerk the plug off again and try again to insert the plug centrally. This lack of feel is eliminated in the invention, which is based on the Fig. 1b is explained. Due to the magnetic interaction with the plug-receiving magnet, the upper edges 5a, 5b of the shielding plates 5 are polarized differently. By means of the drawn arrows which symbolize attraction and repulsion, it can be seen that the magnetic forces of the upper edges of the shielding plates and of the plug-receiving magnet exert a self-centering effect on the plug.

Die Fig. 4a zeigen in perspektivischer Darstellung zwei Magnete 1, 2, die in dem nicht zur Erfindung gehörenden Vergleichsbeispiel nach Fig. 3 verwendet werden. Die Pfeile deuten die austretenden Magnetfeldlinien an, die abgeschirmt werden müssen. Fig. 4b zeigt den verschobenen Zustand, d. h. bei dem der Verschluss geöffnet wird. Die Pfeile symbolisieren die Rückstellkräfte zwischen den verschobenen Magneten, d. h., die Magnete stellen sich automatisch in die Position 4a zurück, wenn die Reibungskräfte zwischen den Magneten ausreichend klein sind.The Fig. 4a show in perspective two magnets 1, 2, which in the non-invention according to the comparative example Fig. 3 be used. The arrows indicate the exiting magnetic field lines, which must be shielded. Fig. 4b shows the shifted state, ie at which the shutter is opened. The arrows symbolize the restoring forces between the shifted magnets, ie, the magnets automatically return to position 4a when the frictional forces between the magnets are sufficiently small.

Die Fig. 5a, b zeigen zwei abgeschirmte Magnete, die in der Erfindung nicht verwendbar sind, da diese Konstruktion nicht über die geforderten Rückstellkräfte verfügt.The Fig. 5a, b show two shielded magnets, which are not usable in the invention, since this construction does not have the required restoring forces.

Die Fig. 6a, b zeigen eine Ausführungsform mit einem einstückigen U-förmigen Abschirmblech 5 nach Anspruch 2. Diese Ausführungsform ist besonders einfach zu montieren und schirmt den Verschluss zusätzlich an der Unterseite magnetisch ab. Dieses Ausführungsbeispiel unterscheidet sich von dem in Fig 1a, 1b gezeigten Ausführungsbeispiel nur dadurch, dass die Abschirmbleche 5, 5' zu einem einzigen, U-förmigen Abschirmblech 5 zusammengefügt sind.The Fig. 6a, b show an embodiment with a one-piece U-shaped shielding plate 5 according to claim 2. This embodiment is particularly easy to install and shields the closure in addition to the bottom magnetically. This embodiment differs from that in FIG Fig 1a, 1b shown embodiment only in that the shielding plates 5, 5 'are assembled into a single, U-shaped shielding plate 5.

Die Fig 7a, b zeigen einen erfindungsgemäßen Magnetsteckverschluss nach Anspruch 1, bei dem der Stecker zum Öffnen bogenförmig seitlich nach rechts oder links herausgeschwenkt wird. Die Abschirmbleche 5,5' überdecken die Magnete 1,2 soweit, dass der Magnetsteckverschluss auf den Außenseiten magnetisch abgeschirmt ist. Die Magnete 1,2 sind quer zur Schließrichtung X magnetisiert. Bis auf die variierte Öffnungsrichtung ist die Funktion identisch mit der Ausführung nach Fig 1 a,b, sodass zur weiteren Erklärung auf diese Figuren verwiesen wird.The Fig. 7a, b show a magnetic plug closure according to the invention according to claim 1, wherein the plug for opening arcuately laterally pivoted to the right or left. The shielding plates 5,5 'cover the magnets 1,2 so far that the magnetic plug on the outside is magnetically shielded. The magnets 1,2 are magnetized transversely to the closing direction X. Except for the varied opening direction, the function is identical to the design according to Fig. 1 a, b, so that reference is made to these figures for further explanation.

Die Fig. 8a,b,c,d zeigen eine Magnetsteckschnalle nach Anspruch 3 in verschiedenen Ansichten. Fig 8d ist eine Vergrößerung der Fig 8a. Das Abschirmblech 5 nimmt hier zusätzlich zur Abschirmung eine weitere Funktion ein: Es ist gleichzeitig die Feder eines Federrastverschlusses, der aus den federnden Abschirmblechflügeln 7a,7b, den mit den Abschirmblechflügeln 7a, 7b verbundenen Rastnasen 6a,6b und den Rastnasen 8a, 8b des Steckers gebildet wird. Das Abschirmblech hat somit eine Doppelfunktion, was die Baugröße des Verschlusses minimiert. Beim Einrasten werden Stecker 3 und Steckeraufnahme 4 durch die Magnete 1, 2 zusammengezogen, bis die Rastnasen 6a,6b und 8a,8b federnd ausweichen und schließlich in einen Eingriff einrasten. Zum Öffnen wird die Magnetsteckschnalle dann seitlich zur Schließrichtung X aufgeschoben.The Fig. 8a, b, c, d show a magnetic buckle according to claim 3 in different views. Fig. 8d is an enlargement of the Fig. 8a , The shielding plate 5 takes here in addition to the shield another function: It is at the same time the spring of a spring latch, which consists of the resilient Abschirmblechflügeln 7a, 7b, connected to the Abschirmblechflügeln 7a, 7b latching lugs 6a, 6b and the locking lugs 8a, 8b of the plug is formed. The shield has thus a double function, which minimizes the size of the closure. When locking plug 3 and connector receptacle 4 are contracted by the magnets 1, 2, until the locking lugs 6a, 6b and 8a, 8b resiliently dodge and finally engage in engagement. To open the magnetic buckle is then pushed laterally to the closing direction X.

In den Fig. 1a, 1b, 2a, 2b, 7a, 7b, 8a-d, 9a-g, 10a-e sind Ausführungsbeispiele dargestellt, die eine Federverrastung aus den Rastnasen 8a, 8b und den Federrastnasen 6a, 6b aufweisen. Beim Schließen zieht die Magnetkraft die Federverrastung selbsttätig zu, wobei die Federrastnasen 6a, 6b federnd ausweichen. Beim Öffnen seitlich zur Schließrichtung X wird die Federverrastung umgangen, d.h. die Federrastnasen 6a,6b werden nicht gespreizt. Der Verschluss wird also ebenso leicht geöffnet, als wenn keine Federverrastung eingebaut wäre. Der Verschluss wird nur durch die seitliche Haltekraft der Magnete an einer Öffnung gehindert, d. h. durch die in Fig. 4b gezeigten und erläuterten Rückstellkräfte gegen Verschiebung. Beim Öffnen des erfindungsgemäßen Verschlusses werden die Magnete haptisch angenehm allmählich voneinander abgeschert.In the Fig. 1a, 1b . 2a, 2b . 7a, 7b . 8a-d . 9a-g . 10a-e Embodiments are shown which have a Federverrastung from the locking lugs 8a, 8b and the spring detents 6a, 6b. When closing the magnetic force pulls the spring lock automatically, the spring detents 6a, 6b resiliently dodge. When opening laterally to the closing direction X, the spring locking is bypassed, ie the spring detents 6a, 6b are not spread. The closure is therefore just as easily opened, as if no Federverrastung would be installed. The closure is prevented only by the lateral holding force of the magnets at an opening, ie by the in Fig. 4b shown and explained restoring forces against displacement. When opening the closure according to the invention, the magnets are haptically pleasant gradually sheared off each other.

Alternativ ist in den Fig 11a-g ein nahe verwandtes Ausführungsbeispiel dargestellt, bei dem während des Öffnens durch ein seitliches Verschieben die Federrastnasen 6a,6b allmählich durch kraftumleitende Schrägen 70a, 70b so weit beiseite gedrückt werden, bis die Rastnasen 8a, 8b und die Federrastnasen 6a, 6b außer Eingriff gelangt sind. Dies ist besonders vorteilhaft, wenn eine vorbestimmte Sicherung gegen unbeabsichtigtes Öffnen gewährleistet werden soll. Fig 11a, b,c zeigen in Untenansicht, Seitenansicht und perspektivischer Ansicht den Steckers 3, an dessen Unterkante die Rastnasen 8a,8b und die kraftumleitenden Schrägen 70a,70b liegen. Fig. 11e-g zeigen in Untenansicht, Seitenansicht und perspektivischer Ansicht die Steckeraufnahme 4 mit den Federrastnasen 6a,6b und zwei weiteren kraftumlenkenden Schrägen 71a,71b. In Zeichnung 11d ist in der linken Schnittansicht der verschobene Offnungszustand gezeichnet, bei dem die kraftumleitenden Schrägen 70a,70b die Federrastnasen 6a,6b soweit gespreizt haben, dass die Rastung außer Eingriff gelangt ist. Gleichzeitig wurden die Magnete 1,2 allmählich voneinander abgeschert, d. h. abgeschoben. Die Abschirmbleche 5,5' sind an der Steckeraufnahme angebracht. Sie überdecken im geschlossenen Zustand die Magnete 1,2 so weit, dass der Verschluss so weit wie erforderlich abgeschirmt ist.Alternatively, in the Fig. 11a-g a closely related embodiment shown in which during opening by a lateral displacement the spring detent lugs 6a, 6b are gradually pushed aside by kraftumleitende bevels 70a, 70b as far as the locking lugs 8a, 8b and the spring detents 6a, 6b are disengaged. This is particularly advantageous if a predetermined safeguard against unintentional opening is to be ensured. 11a, b, c show in bottom view, side view and perspective view of the plug 3, at the lower edge of the locking lugs 8a, 8b and the kraftumleitenden bevels 70a, 70b are. Fig. 11e-g show in bottom view, side view and perspective view of the plug receptacle 4 with the spring detents 6a, 6b and two other kraftumlenkenden bevels 71a, 71b. In drawing 11d is drawn in the left sectional view of the shifted opening state in which the kraftumleitenden bevels 70a, 70b the spring detents 6a, 6b have spread so far that the detent has come out of engagement. At the same time, the magnets 1,2 were gradually sheared off from each other, ie deported. The shielding plates 5,5 'are attached to the connector receptacle. When closed, they cover the magnets 1, 2 so far that the closure is shielded as far as necessary.

Auch ohne die Federverrastung ist ein haptisch angenehm zu schließender, wie angenehm zu öffnender Verschluss bereitgestellt, der durch die Abschirmbleche abgeschirmt ist.Even without the Federverrastung is provided a haptic pleasant to close, as pleasant to open closure, which is shielded by the shielding.

Die Figuren 9a-g zeigen ein Ausführungsbeispiel, in dem zwei Abschirmbleche 5,5' am Stecker angebracht sind. Fig. 9a zeigt den geschlossenen Zustand, in dem die Abschirmbleche die Magnete so weit überdecken, dass der Verschluss so weit wie erforderlich abgeschirmt ist. Fig 9c zeigt den offenen Zustand kurz vor Schließung. Hier sind mit Pfeilen die Absto-βungseffekte zwischen den Vorderkanten der Abschirmbleche 5,5', die wie gezeichnet Nord (N) und Süd (S) polarisiert sind, und dem Nord- und Südpol des Steckeraufnahmemagnets 2 gezeichnet. Diese tragen neben den vorhandenen Anziehungskräften zur Selbstzentrierung von Stecker und Steckeraufnahme bei. In Fig. 9e ist eine unerwünschte Position gezeichnet, in der Stecker und Steckeraufnahme ungünstig verhakt sind. Durch die erfindungsgemäß quer zur Schließrichtung x verlaufende Magnetisierung und damit einhergehenden Polarisierungen der Vorderkanten der Abschirmbleche 5,5' entstehen Abstoßungseffekte in dieser unerwünschten Position, d.h. der Verschluss kann sich dort nicht verhaken und der Stecker zentriert sich von selbst in der Steckeraufnahme. Die Fig. 9g zeigt den geöffneten Verschluss in perspektivischer Ansicht. Wie oben beschrieben, besteht eine Federverrastung zwischen den Rastnasen 8a,8b und den Federrastnasen 6a,6b.The Figures 9a-g show an embodiment in which two shielding plates 5, 5 'are attached to the plug. Fig. 9a shows the closed state in which the shields cover the magnets so far that the shutter is shielded as far as necessary. Fig. 9c shows the open state just before closing. Here are the Absto-βungseffekte between the leading edges of the shielding plates 5,5 ', which are polarized as drawn north (N) and south (S) and the north and south pole of the plug-receiving magnet 2 with arrows. In addition to the existing attractions, these contribute to the self-centering of the plug and plug receptacle. In Fig. 9e is an undesired position drawn are hooked unfavorable in the plug and plug receptacle. Due to the inventively transverse to the closing direction x magnetization and associated polarization of the leading edges of the shields 5,5 'arise repulsion effects in this undesirable position, ie the closure can not get caught there and the plug is centered by itself in the connector receptacle. The Fig. 9g shows the opened shutter in perspective view. As described above, there is a spring latching between the latching lugs 8a, 8b and the spring latching noses 6a, 6b.

Im Ausführungsbeispiel nach Fig 10a-e ist sowohl am Stecker 3, wie an der Steckeraufnahme 4 je ein Abschirmblech vorgesehen. Im geschlossenen Zustand nach Fig 10a überdecken diese die Magnete 1,2 so weit wie für eine ausreichende Abschirmung nötig ist. Stecker und Steckeraufnahme sind baugleich ausgeführt - dies ist vorteilhaft, da nur ein Bauteil produziert werden muss. Auch hier sorgt die erfindungsgemäße Polarisierung der Magnete dafür, dass der Verschluss sich zuverlässig selbstzentrierend schließt. Fig 10c zeigt den offenen Zustand und 10e eine perspektivische Ansicht des offenen Verschlusses.In the embodiment according to Fig. 10a-e is provided both on the plug 3, as on the connector receptacle 4 depending on a shield. In the closed state after Fig. 10a These cover the magnets 1,2 as far as necessary for adequate shielding. Plug and plug receptacle are identical in design - this is advantageous because only one component must be produced. Again, the inventive polarization of the magnets ensures that the closure closes reliably self-centering. Fig. 10c shows the open state and 10e a perspective view of the open closure.

Dem Fachmann ist klar, dass nach dieser technischen Lehre eine Vielzahl von abgeschirmten Magnetverschlüssen gebaut werden kann, wobei die Bewegungsrichtung der Module zueinander beim Öffnen auch ein Kippen oder ein Drehen sein kann. Ein optionaler mechanischer Rastverschluss kann entweder seitlich umgangen werden oder die Rastfedern können während der Verschiebung allmählich aufgedrückt werden. Außerdem kann das U-förmige Abschirmblech auch Teil des mechanischen Rastverschlusses sein. Der Verschluss kann als Steckschnalle ausgebildet sein mit Gurtanbindungen, er kann als Taschenverschluss auf einer Seite oder beiden Seiten fest mit Deckel oder Boden der Tasche z.B. durch Aufschweißen verbunden sein. Er kann in Koffern o. a. Behältnissen integriert sein. Diese Aufzählung von Anwendungen schränkt jedoch die Anwendbarkeit der Erfindung nicht ein.It is clear to the person skilled in the art that according to this technical teaching a multiplicity of shielded magnetic closures can be built, wherein the direction of movement of the modules relative to one another during opening can also be tilting or turning. An optional mechanical latch can either be bypassed laterally or the detent springs can be gradually pushed open during the shift. In addition, the U-shaped shield may also be part of the mechanical snap lock. The closure can be designed as a buckle with Gurtanbindungen, he can as a pocket closure on one side or both sides fixed to the lid or bottom of the bag, for. be connected by welding. He can in suitcases o. A. Be integrated into containers. However, this list of applications does not limit the applicability of the invention.
