Description

The The invention relates to a fastening device for an assembly on a mounting rail, wherein the mounting rail at least a first Holding leg and the assembly at least one complementary first Has leg receiving, with the first holding leg of the Support rail can be brought into operative connection to form at least one first attachment point between mounting rail and module.

Under Support rail are here in particular DIN rails to understand the usually distributed and used in standardized form. They usually have a base leg on which the at least a holding leg is connected in an L-shape. The DIN rails are mostly about the Base leg on a vertical surface, such as a wall a control cabinet mounted, wherein the first retaining leg so pointing upwards parallel to the wall shows that the thigh seat of the Assembly hung in it can be. Of course fall under the name support rail but also any other Type of supporting structures, the inclusion of the aforementioned assembly, can serve. For the sake of simplicity, however, in the following example, under mounting rail Such a top hat rail described above understood that at a vertical wall is mounted.

Under Assembly here are all Systems, elements and devices understood on such Mounting rails are attachable. In particular, including electronic Components such as safety switches, overcurrent protection switches, terminals, Power supplies, power supplies or similar components subsumed.

such Fasteners for assemblies on a mounting rail are known from the prior art.

That's how it describes DD 1 571 32 a device for quick attachment of electrical switching devices on a mounting rail by means of a guided on a housing bottom of an assembly, spring-mounted fastener in the form of a clamping slide. To set the assembly to the support rail of the clamping slide is pressed from an open position to a closed position, wherein a spring element is brought in the clamping slide on bias and so fixes the assembly to the mounting rail.

Also the DE 20 2004 019 381 U1 shows a device for snap mounting of modules on a mounting rail, wherein the assembly has a fastener with a hook-shaped holder for Üqerbreifen a retaining leg of the support rail and a pivotable lever for locking behind another holding leg of the support rail. This fastener is integrally formed of plastic on a housing of the assembly.

The mentioned fastening devices, however, usually have the disadvantage that they due to their displaceable or pivotable or elastic To make fasteners for a costly, for others but also a frequent one Assembly and disassembly without damage are not up to it. Especially when snapping the aforementioned Fastener on the mounting rail is often used a failure of the elastic fasteners and so to a Failure of the entire fastening device.

Furthermore previously mentioned systems usually require a certain contact pressure during assembly of the assemblies, which is particularly the case of very cramped Space conditions and above In addition, especially in the field of electronics usually very problematic is.

Also Fastening devices with sliding or movable fasteners, such as the above-mentioned clamping slide, are in terms of their installation especially in very confined spaces very disadvantageous because usually the place to operate the fasteners is missing. The same applies to disassembly, as usually under large Space requirements accessibility to the corresponding locking devices and in particular must be ensured mostly from several directions.

There moreover, in the case of the abovementioned "snap-in" fastening devices, just when releasing the assembly of the mounting rail, very high dismantling forces occur it is necessary the mounting rail very stable on a wall or a control cabinet etc. to attach.

present The invention is therefore based on the object, a fastening device of the aforementioned type so that they are the simpler Assembly of an assembly on a mounting rail, in particular also in confined spaces, allows at the same time simpler construction.

These The object is achieved by a fastening device according to claim 1 solved.

In particular, this object is achieved by a fastening device for a module on a mounting rail, the mounting rail wenigs at least one first retaining leg and the assembly has at least one complementary first leg receptacle which is operatively engageable with the first support leg of the support rail to form at least a first attachment point between support rail and assembly and wherein at least one magnetic force connection element is provided to form at least a second Fixing point between the mounting rail and the module.

One Advantage of this fastening device is that a very simple and especially tool-free assembly of modules a support rail possible is. In particular, the combination of a holding leg and a corresponding leg receiving formed first attachment point and a second attachment point formed by magnetic force leads to no sliding, movable or otherwise elastic clamping or locking components must be formed. This increases in crucial Measures the Durability of the fastening device and improves the assembly and disassembly behavior, since the applied forces are reduced. In addition allows the locking by means of magnetic force targeted influencing the locking force by the appropriate choice of the used Magnetic force connecting element.

Preferably the fastening device has at least one in particular releasable fastening element on, on which the leg receptacle and the magnetic force connecting element are arranged. Under fastener here are both solid with the respective assembly connected fasteners, as also detachable Fastening elements subsumed, which are correspondingly complementary to the mounting rail be formed to allow a connection with this. The advantage of such an embodiment lies in the almost every assembly with the fastening device according to the invention can be made compatible by the assembly with the fastener is provided. In this respect, all the following specifications apply the assembly accordingly the connected to the assembly or connectable to this fastener.

Preferably the magnetic force connection element has at least one magnetic element on the module or the fastening element and at least one complementary Magnetic element recording on the mounting rail on. The arrangement of the magnets can over it known adhesive, screw, plug or similar connections made. The choice of the magnet itself can be dependent on the required magnetic connection force, the required height the fastening device etc. are taken. In this context is it u. a. conceivable, depending on the assembly to be attached special To use magnets based on the weight and dimensions of the are matched to corresponding modules. For this purpose, a permanent magnet is preferred used.

With the fastening device according to the invention Is it possible, to assemble the assembly without the use of special locking forces after the formation of the first attachment point, for example the hanging the first leg receptacle in the first holding leg, a fixation the module to the mounting rail at the second attachment point in Essentially through the activation of the magnetic force connection element or the assignment of the magnetic element to the magnetic element holder he follows.

advantageously, the first and the second attachment point are arranged so that the first, in mounting upper attachment point, the introduction permanent Loads in the mounting rail, so in particular the weight of the Assembly serves while the second attachment point of the position fixing of the module the support rail in particular against externally acting forces, vibrations etc. is used. So in the first attachment point is the weight out of the module in a vertical direction downwards into the mounting rail removed, so serves the magnetic force connecting element of the position fixing the assembly substantially in a horizontal direction away from the mounting rail. Naturally can but also forces be removed in the horizontal direction to the mounting rail out by the magnetic force locking element acts as a bearing block of the in particular transfers compressive forces. moreover It is also conceivable, an introduction of force via between the magnetic element and the magnetic element receiving resulting frictional forces.

Preferably The first leg receptacle engages around the first holding leg Formation of a first attachment point hook-shaped, so that the assembly in this first attachment point vertically downwards and horizontally fixed to the mounting rail and away from it in their storage is. Thus, therefore, does not take place in this first attachment point only one weight force derivation in vertical direction downwards, but also in particular a power dissipation due to an acting Exzentrizitätsmomentes. As before, the magnetic force connecting element serves over the resulting Magnetic binding forces the position fixing of the assembly in the horizontal direction at least away from the mounting rail. Naturally but can also as described above forces be removed in the horizontal direction to the mounting rail out.

The magnetic force connection is preferred arranged element in the greatest possible distance from the first hook-shaped attachment point to achieve a particularly effective introduction of force. Of course, however, the use of multiple magnetic force connecting elements is possible, which can be arranged depending on the assembly, load and training of the mounting rail, on the base leg, the holding leg or other holding legs.

Preferably At least the first leg receptacle surrounds the first holding leg forming a first attachment point so that the assembly in this first attachment point only vertically down in her Storage is fixed, wherein also the magnetic force connecting element such is arranged, that the assembly at least horizontally from the Support rail is fixed away in their storage. The fixation horizontal on the mounting rail to then either through the leg receptacle and the corresponding holding leg or via another bearing block, which is designed for this purpose on the mounting rail done. Also, as mentioned above the use of the magnetic force locking element as a bearing block possible. Such an embodiment is particularly advantageous in confined spaces, since they are the linear insertion of the module in or on the mounting rail allowed. There are no pivoting movements needed here in particular the first Form attachment point, so that when mounting the mounting rail, the module simply be moved in a horizontal direction to the mounting rail can until the magnetic force connection element is activated. The first Leg receiving serves essentially during the assembly process as a guide, to ensure a correct fit of the module to the mounting rail. Only after installation, it then serves in addition to the vertical weight dissipation.

Just In addition, due to this linear insertion, none of them are involved Components elastically deformed, for example, as described above, in the form of swivel or Clamping movements etc., what the durability of the fastening device elevated and the requirements for the material used and thus the production costs reduced.

Next the smaller space requirements when inserting the module the mounting rail, the assembly forces are also reduced in this embodiment, So the forces, the necessary are to secure the module to the mounting rail. As before already mentioned, are no elastic deformation work necessary, but it is only one friction occurring in very narrow "fits" between the thigh shots and the thighs overcome to get into the sphere of action of the magnetic force connection element, in which the magnetic force presses the module to the mounting rail.

Around in this embodiment In addition, certainly an eccentricity moment take the assembly, it is recommended that a plurality of Magnetic force to use elements, in which case preferred at least one at the top of the mounting rail, so close to or even can be arranged on the first holding leg, to abort at the aforementioned moment.

in the Generally, a support rail and in particular one of the Known prior art hat rail a second holding leg, essentially parallel to the first holding leg. The assembly or the fastener then preferably also has one second leg receptacle, with the second holding leg under Formation of a third attachment point brought into operative connection can be. Here, as before, the training of this third attachment point conceivable that the assembly against movements perpendicular to above and horizontally fixed to the mounting rail in their storage is. In this way, by the two first and second leg recordings in conjunction with the first and second holding legs a guide for insertion the assembly is formed, so that no mispositioning of the module in vertical direction downwards and upwards relative to the mounting rail, to fear is. About that In addition, the assembly is safe even after completion of assembly this vertical direction, and also both in terms of a Movement kept down as well as up. Here is again the use of one or more magnetic force connection elements for fixing the position of the assembly in the horizontal direction, so that the magnetic force presses the module to the mounting rail.

As a general rule be mentioned that in the fastening device according to the invention the formation of storage areas for positioning the module on the DIN rail in a horizontal position Direction to the mounting rail, both by an appropriate training the magnetic force connecting elements as bearing blocks or even by a appropriate training of the support rail or its holding leg as such bearing blocks can be done. It should also be noted that the respective retaining leg and thighs of course also be able to be trained that an introduction of force either only in a rich direction of said attachment axis or but can be done in both directions, so for example only vertically downwards or downwards and upwards or horizontally away from the mounting rail and / or to this.

Independent of the training of the first attachment point is used, as already mentioned, the second holding leg or the second leg receptacle as a guide at Inserting the module onto the mounting rail. For example the first leg receptacle formed such that it the first Holding leg hook-shaped engages around, so the assembly can first on the first leg receptacle be hooked into the first holding leg, and then stands behind the pivoting of the assembly about this first attachment point with the second leg receptacle on the second holding leg, the causes a position fixation in a vertical upward direction.

There the required position of the respective mounting axles of course depends on the arrangement of the mounting rail in space, these conditions can at changed Arrangement of the mounting rail on a wall, a slope or a blanket, of course, changing, taking According to the invention, the attachment points and the magnetic force connection elements are adaptable thereto.

Preferably is at least one force element between the mounting rail and assembly or spring element arranged such that it is the assembly of the Guide rail away. Even if between the respective holding legs and the leg holders a relative play exists, provides the aforementioned Force element or spring element after the in-effect bring the magnetic force connection element for this, that the module is securely and firmly fixed to the mounting rail. Without the use of such a force element, it might be due to the Game between holding leg and thigh receptacle to a rattle or to a movement of the assembly in its storage. Preferably in this context, the force element is to be arranged close to the position, where such a game has to be compensated, for example near a corresponding leg receptacle and the complementary holding leg. Naturally is also the arrangement of a force element and in particular one Leaf spring in a thigh recording itself conceivable, which then in-operatively bringing the leg receptacle and the retaining leg applies a bias such that a tight fit in interaction ensured with the magnetic force connecting element. Here are all conceivable from the prior art spring structures conceivable.

Preferably has the magnetic force connection element or the magnetic element and / or the magnetic element receiving a preferably resilient game element on, to compensate for inaccuracies between the mounting rail and the assembly. Such a game element is for example off the furniture construction is known and installed there in a so-called magnetic door closer. Accordingly, in the present fastening device, for example the magnetic element one or more axially movable on a thin mounting plate attached to the assembly or the fastener is attached. The complementary Magnetic recording element can then even at meetings in between the module and the mounting rail due to the movably mounted Magnetic element with this in operative connection, so that a firm connection between the two components arises. Again, here is In addition, the use of a force element such as a Spring on the game element conceivable for a solid storage without rattling etc. to guarantee.

Preferably the support rail is at least partially made of a material, that with the magnetic element or the magnetic force connecting element can be brought into operative connection, in particular of a ferromagnetic Material. In this way, a direct operative connection between the magnetic element and the ferromagnetic support rail made become.

Further embodiments The invention will become apparent from the dependent claims.

in the Below, the present invention will be described with reference to exemplary embodiments described, which are explained in more detail with reference to the accompanying drawings. Hereby show:

12 an isometric view of a fastener according to 11 ,

For same and like components will be described in the following description the same reference numbers used.

The 1 and 2 each show an isometric view of a first embodiment of the fastening device according to the invention for an assembly 8th , It shows

1 a front view and 2 a rear view. Shown is the assembly 8th , which is exemplified here as a housing and is representative of all components to be fastened, such as circuit breakers, circuit breakers, coupling and branching components or similar electronic or non-electronic components. The assembly 8th will, as in 2 to recognize, via a fastener 20 on a mounting rail 10 attached. This mounting rail 10 has a main extension axis, which here runs parallel to a horizontal axis A _Z1 -A _Z1 .

The mounting rail 10 itself is here designed as a standard and known from the prior art hat rail, the two holding legs 12 . 16 and a base leg 14 includes, over which the mounting rail 10 on a wall, a control box or similar component (not shown) can be attached. The orientation of the DIN rail shown here 10 corresponds to the orientation when mounted on a vertical wall.

The fastener 20 has a leg receptacle 22 on that the first holding leg 12 so embraces that the fastener 20 and the assembly attached to it 8th both vertically downwards (mounting axis A _Y1 -A _Y1 ) and along a direction substantially orthogonal thereto, namely horizontal and to the mounting rail 10 towards and away from it (fixing axis A _X1 -A _X1 ) are fixed. This so-called first attachment point 1 In this embodiment, therefore, it is essentially the load transfer due to its own weight in the direction of the axis A _Y1 -A _Y1 and due to a force from the eccentricity moment in the direction of the axis A _X1 -A _X1 .

Depending on the design of the retaining leg 12 and the leg receiving around it 22 a frictional force forms, which in turn is the assembly 8th fixed in the direction of the axis A _Z1 -A _Z1 .

In the area of the retaining leg 16 is through the use of a magnetic fastener 30 (please refer 3 and 4 ) a second attachment point 2 educated.

The 3 and 4 show an insertion of the assembly 8th in its storage on the mounting rail 10 using the fastening device according to the invention. The assembly is shown 8th that the fastener 20 has, on which the Schen kelaufnahme 22 is formed, with the holding leg 12 the mounting rail 10 can be brought into operative connection.

Further illustrated is the magnetic force connection element 30 that is a magnetic element 32 and a magnetic element holder 34 includes. The magnetic element 32 is in this embodiment on the fastener 20 arranged while the magnetic element recording 34 integral with the mounting rail 10 is trained. This integral design results from the choice of material of the mounting rail 10 , here as a ferromagnetic mounting rail 10 was trained. After pivoting the magnetic element 32 together with the assembly 8th in the direction of the magnetic element holder 34 affects between the magnetic element 32 and the magnetic element holder 34 a magnetic force that presses the module to the mounting rail. In other words, a magnetic force acts along a magnet mounting axis A -A _{MX MX,} the assembly 8th in their position in the horizontal direction and from the mounting rail 10 fixed away and so a second attachment point 2 the assembly 8th forms. The fixing in position horizontally on the mounting rail also takes place here through the magnetic element 32 , which acts as a bearing block and transmits pressure forces from the module into the mounting rail.

The first attachment point is, as already mentioned, by hooking the retaining leg 12 in the thigh recording 22 educated. Because the thigh receptacle 22 the holding leg 12 engages, form two attachment axes, namely a vertical mounting axis A _Y1 -A _Y1 and a horizontal mounting axis A _X1 -A _X1 , which extends substantially parallel to the magnetic axis A _MX -A _MX .

In this embodiment, the mounting rail 10 arranged so that the weight g the assembly 8th parallel to axis A -A _{y1 y1,} vertically pulls downwards. In this respect, therefore, the primary load dissipation takes place via the first attachment point 1 from the thigh recording 22 over the holding leg 12 in the mounting rail 10 , Of course it is also possible, the mounting rail 10 to arrange so that the weight g acts, for example, in the direction of the axes A _X1 -A _X1 . This would mean that a part of the weight g would have to be removed by the magnetic force along the axis A _MX - _MX . In this respect, here would be only a suitable choice of the magnetic force connecting element 30 to pay attention.

The 5 - 9 Now show further embodiments 2-6 of the fastening device according to the invention.

5 shows a second embodiment of the fastening device according to the invention. Shown is, as in the first embodiment, the fastener 20 and the leg receptacle formed thereon 22 into which the retaining thigh 12 the mounting rail 10 is hooked. In this respect also takes over the combination of retaining leg 12 and thigh recording 22 a 2-axial attachment along the vertical and horizontal axes A _X1 -A _X1 and A _Y1 -A _Y1 . In addition, in this embodiment, two magnetic force connection elements 30 . 30 ' provided, each cause a magnetic force, the assembly 8th to the mounting rail 10 pressed. To ensure a secure fit of these two magnetic force connection elements 30 . 30 ' and to achieve a secure locking effect, the elements also serve as bearing blocks between the fastener 20 and the mounting rail 10 or in this case the base leg 14 the mounting rail 10 , It should be mentioned, of course, an arrangement of the magnetic force connecting elements 30 respectively. 30 ' on the retaining leg or another position of the mounting rail 10 it is possible.

The magnetic force connection elements 30 . 30 ' have a magnetic element as in the first embodiment 32 and a magnetic receiving element 34 with reference to corresponding passages. Also in this embodiment, it is thus so that the weight force g of the assembly to be fastened 8th essentially at the attachment point 1 is received, while in particular from the magnetic force connection elements 30 . 30 ' resulting horizontally acting magnetic forces along the axes A _MX -A _MX or A ' _MX -A' _MX serve only to fix the position, but due to the majority of magnets, but to ensure a more stable positional fixation.

The 6 and 7 each show a third and fourth embodiment of the device according to the invention, wherein the fastener 20 a second leg receptacle 26 is formed, which is substantially parallel to the first leg receiving 22 runs. This second leg intake 26 stands in operative connection with a second holding leg 16 which is attached to the mounting rail 10 is trained. Both components together form a third attachment point 3 , which is designed here as a 1-axial attachment point. This means that only along a vertical axis A _Y3 -A _Y3 a force dissipation from the assembly or the fastener 20 in the mounting rail 10 he follows.

The in the 6 and 7 The embodiments shown are essentially different in that 6 the known from the first two embodiments encompassing, hook-shaped design of leg holder 22 and the holding leg 12 is present. So that means that here too the assembly 8th together with the fastener 20 essentially via a pivoting movement on the mounting rail 10 is attached (see the example of the 3 and 4 ).

In contrast, according to the embodiment. 7 the thigh recording 22 executed only as a cantilevered component, which the holding leg 12 the mounting rail 10 does not surround. As a result, only a force dissipation between fastener takes place here 20 and mounting rail 10 in the vertical direction downwards (in the direction of the attachment axis A _Y1 -A _Y1 ). As already mentioned, the fastener 20 also a second leg receptacle 26 formed substantially parallel to the first leg receiving 22 runs and with the second holding leg 16 the third attachment point 3 forms, and so a power dissipation from the module in the mounting rail 10 vertically upwards (along the axis A _Y3 -A _Y3 ) guaranteed. A position fixation in a horizontal axis orthogonal thereto takes place in this embodiment, the two magnetic force connection elements 30 . 30 ' whose magnetic force runs along two magnetic connection axes A _MX -A _MX and A ' _MX -A' _MX .

The advantage of this embodiment lies in the fact that the insertion and removal of the assembly 8th can be done without a pivoting movement. Rather, it is simply possible, the assembly 8th essentially horizontal, ie parallel to the axis A _MX -A _MX on the mounting rail 10 to move until the magnetic force connecting elements 30 . 30 ' unfold their effect and press the module onto the carrier rail. Since the magnetic force connecting elements 30 . 30 ' are formed according to the embodiments described above, this means that the respective magnetic element 32 with the magnetic element holder 34 is in active connection (see 4 ).

The 8th and 9 show embodiments that, inter alia, a problem of possible manufacturing inaccuracies or. Inaccuracies due to contamination etc. take into account.

8th shows an embodiment in which between the base leg 14 the mounting rail 10 and the fastener 22 a force element or here a spring element 36 is arranged, the additional positional fixation between mounting rail 10 and fastener 22 or assembly 8th serves. Especially with construction inaccuracies in the area of the attachment point 1 , So a game between holding leg and leg receptacle, can through the over the spring element 36 applied spring force along a spring axis A _F -A _F parallel to the magnetic locking force along the axis A _MX -A _MX a safe and especially "damped" seat are ensured so that, for example, the components do not rattle against each other or vibrate uncontrollably said spring element 26 also an adaptation of the locking force that the assembly 8th via the magnetic force connecting element 30 on the mounting rail 10 fixed. Advantageously, in this embodiment shown here, the spring element is arranged close to the position, here the attachment point 1 where there is a game to compensate.

9 on the other hand shows an embodiment in which the at the attachment point 2 arranged magnetic force locking element 30 a game element 38 has, so that between the magnetic element 32 and the magnetic element holder 34 forms a predefined game, in particular to compensate for contact inaccuracies between the mounting rail and the fastener. Through the game element 38 , which in this embodiment in the direction of the horizontal axis A _MX -A _MX slightly from the mounting rail 10 away and can be moved towards this, can, even with any deviations in the dimensions of the mounting rail 10 , the fastener 20 etc. of the full-surface seat between the individual components of the magnetic force fastening element 30 be guaranteed. Of course it is conceivable, even several game elements 38 to be able to provide a compensation even in the case of major inaccuracies or similar inaccuracies. Here are all known from the prior art methods and apparatuses that can serve to compensate for inaccuracies in the meeting or similar inaccuracies.

10 finally shows a partial side view of another embodiment in a detailed representation. Shown is a first attachment point 1 by a first hook leg 12 the mounting rail 10 and a complementary leg receptacle 22 of the fastening element 20 an assembly (not shown) is formed. Further shown is a magnetic force connection element 30 that between the mounting rail 10 and the fastener 20 is arranged. This magnetic force connecting element 30 has, as already described above, a magnetic element 32 on top, that with a magnetic element pickup 34 passing through the ferromagnetic mounting rail 10 is formed, is operatively connected. In addition, the magnetic force connecting element 30 a game element 38 on that over a force element 3G with the magnetic element 34 connected is. In this way, it is possible inaccuracies in the area of the first attachment point, here inaccuracies, for example 1 , compensate, without affecting the operation of the magnetic force connection element 30 is worsened.

The 11 and 12 show a further embodiment of the fastening device according to the invention.

In 11 is a fastener 20 shown that a first hook-shaped leg receptacle 22 and a second only acting as a sliding guide second leg receptacle 2G includes. In this respect, fixing axes A _x , A _y are formed here according to the embodiment 6 out. The fastener shown here 20 is at the assembly 8th fastened by screw or similar connection (not shown).

Between the first leg intake 22 and the second leg receptacle 2G is an intermediate element 39 arranged, in the substantially accurate fit a plurality of magnetic fasteners 30 , here magnetic elements 32 , are inserted. For this purpose, the intermediate element 39 corresponding recesses 37 on, which is a substantially flush and accurate fit recording of the magnetic elements 30 allow. In this embodiment, so are the magnetic elements 32 in direct magnetic interaction with the corresponding magnetic element recordings 34 , here by the ferromagnetically designed holding leg 12 . 16 be formed. Of course it is also possible the magnetic element 32 without the intermediate element 39 on the fastener 20 or even to attach directly to the module (not shown).
