Definitions

• the invention relates to a shielded magnetic closure, the magnetically sensitive instruments or objects, such.
• magnetically sensitive instruments or objects such.
• 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.
• FIGS. 4a, 4b In order to be able to represent the problems of shielding a magnetic closure more clearly, only the magnets of such a closure are shown in FIGS. 4a, 4b, ie the housing for the plug and the housing for the plug receptacle are not drawn.
• FIG. 4a shows that the north and south poles face each other so that maximum attraction is ensured.
• the shutter 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.
• magnetic guide plates can be used. These magnetic guide plates and their effect are shown in Fig. 5 and already known from the prior art. As can be seen from FIGS. 5a and 5b, neither in the closed state of the closure nor when the closure is open do almost no magnetic fields appear on the outer sides of the closure, which would be desirable for this closure. Nevertheless, this type of shield for closures of Fig. 4 is not applicable. This has the following reason:
• the magnet arrangements according to FIG. 4 have the property of automatically resetting themselves in the event of a lateral displacement.
• This feature is well known in the art and is used in some types of magnetic closures, e.g. B. to improve the opening haptics.
• This will be described with reference to Fig. 4b:
• the arrows between the mutually offset magnetic surfaces symbolize the remindstellkarfte.
• 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.
• the arrangement shown in Fig. 5, however, does not have this restoring force. In this respect, on the one hand, an arrangement according to FIG.
• FIG. 4 A magnet arrangement according to FIG. 4 is 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.
• shielding plates 5, 5 ' were arranged in the plug receptacle.
• This agent has proved to be suitable for sufficiently shielding the magnetic stray lines to the outside.
• 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 according to 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-hand side edge of the plug receptacle, because in the plug magnet the south pole is at the front and unlike poles are tightened.
• a magnetic plug closure according to claim 1, wherein the one plug and a plug receptacle.
• 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.
• 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.
• the plug magnet and the Steckerabilitymag- net 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. When plug-in Magnets are reversed poles, so tighten the plug and plug receptacle each other. In other words, the plug magnet and the plug receptacle magnet are oppositely polarized.
• 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 is clear to the person skilled in the art that the properties of the ferromagnetic material itself and its thickness influence the shielding properties of the shielding plates, so that the expert also takes into account the material and the 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.
• 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.
• the magnetic force relationships will be explained in more detail.
• the closure according to the invention has a significantly improved closing feel with at the same time good shielding of the magnetic field.
• the invention is developed so that when closing in the closing direction X is a spring latching between the plug and plug recording 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.
• the springs of Federverrastung are not spread when opening, the springs are spread in a very similar development of the invention.
• 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.
• This embodiment requires a higher expenditure of force during opening, since both the magnets must be sheared off from one another and, in addition, the detent spring has to be spread open. However, this feature can be beneficial for closures that are not allowed to open accidentally.
• two lateral shielding plates are connected to a one-piece sheet metal.
• the magnetic field scattering can be further reduced and the mounting of the shielding plate is facilitated.
• FIG. 6a, 6b This embodiment differs from that shown in FIGS. 1a, 1b only in that the shielding plates 5, 5 'are assembled into a single, U-shaped shielding plate 5.
• 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.
• FIG. 1a, b show an embodiment of the invention in the open state, wherein the shielding plates are arranged on the connector receptacle.
• Fig. 2a, b show an embodiment of the invention in the closed state.

• 1 and 2 are rod-shaped magnets which extend across the width of the magnetic plug closure shown in Fig. 1a and in this example have a square cross-section. With N for North Pole and S for South Pole magnetization is designated. The magnetization extends transversely to the closing direction X, in which the plug 3 is inserted into the plug receptacle 4 and the spring latching of the latching lugs 8a, 8b and the resilient spring latching noses 6a, 6b engages.
• 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.
• the upper edges 5a, 5b of the shields 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 connector 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 explained with reference to FIG. 1 b.

• FIGS. 7a, b show a magnetic plug-type closure according to the invention according to claim 1, in which the plug is swung out to open in an arcuate manner laterally to the right or left.
• the shielding plates 5,5 ' cover the magnets 1, 2 so far that the magnetic plug closure 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 embodiment according to FIG. 1a, b, so that reference is made to these figures for further explanation.
