Description

[0001] The invention relates to a mounting device for attaching an electrical component to an object. The invention further relates to a set for forming such a mounting device.

[0002] In electrical installation technology, various mounting solutions exist for attaching electrical components to designated mounting surfaces and structures. For example, so-called DIN rail adapters can be used to attach electrical assemblies to DIN rails. Furthermore, distribution modules or terminal blocks, for instance, can be fixed to mounting plates to enable compact arrangement within an installation environment.

[0003] To reduce installation effort and assembly time, it is desirable in practice to provide mounting systems that are characterized by user-friendly application, a simple and robust design, and cost-effective manufacturing. Furthermore, due to the wide variety of electrical components, it is desirable to be able to use flexibly applicable mounting systems in order to keep as few different mounting models as possible on hand.

[0004] Against this background, the invention aims to create an improved mounting device and a set for forming such a mounting device, which, with flexible application possibilities and economical manufacturability, enables simple and reliable attachment of an electrical component to an object.

[0005] The problem is solved by a mounting device according to claim 1 and by a set for forming a mounting device according to claim 21. Advantageous embodiments are disclosed in the dependent claims, the description, and the figures.

[0006] According to the features of independent claim 1, a mounting device for attaching an electrical component to an object is proposed, wherein the mounting device has a base module with first connecting elements, a first holding module with second connecting elements and a counter bearing attached to the base module, wherein the first holding module with its second connecting elements can be connected to the base module with the first connecting elements and can be fixed at a variable position on the base module selectable by the user, and wherein a receiving space is formed between the first holding module and the counter bearing in which the electrical component to be attached can be at least partially received and fixed between the first holding module and the counter bearing on the mounting device.

[0007] The mounting device, as proposed, offers the advantage that the first mounting module, which can be variably positioned on the base module, allows the space between the first mounting module and the counter bearing to be adapted to the electrical component being mounted. This enables electrical components of varying sizes to be attached to a single object using the mounting device. Furthermore, the modular design allows for differently shaped first mounting modules to be attached to the base module, thus enabling flexible and customized mounting solutions. The mounting device has a simple structure consisting of a base module, a first mounting module, and a counter bearing, making it easy to handle and cost-effective to manufacture.The first connecting elements of the base module and the second connecting elements of the first holding module allow the first holding module to be securely positioned on the base module, so that the electrical component can be reliably received and held in the receiving space.

[0008] A mounting device can be understood as a mechanical functional unit designed for the form-fitting and / or force-fit fixing of an electrical component. The mounting device can be arranged on an object, such as an electrical device or an electrical installation unit, and optionally attached to it. The base module can, for example, be designed as a mounting plate that can be arranged on the object and can serve as a support for the counter bearing and the first mounting module. The base module can have a mounting surface from which a receiving section of the counter bearing and a receiving section of the first mounting module connected to the base module, between which the receiving space can be formed, project, in particular, substantially perpendicularly.The receiving space formed between the first mounting module and the counter bearing can be further limited by the mounting surface of the base module. The electrical component to be mounted can be at least partially contained within the receiving space, meaning that the electrical component does not have to be completely contained within the receiving space formed between the first mounting module and the counter bearing, but can project out of the receiving space in at least one spatial direction into the surrounding area of ​​the mounting device.

[0009] According to one embodiment, the first holding module can be guided in a first spatial direction by guide elements formed on the base module and fixed at a variable position. This enables safe and intuitive handling of the holding device when positioning the first holding module. The guide elements can, for example, be configured to allow linear guidance of the first holding module along the base module. The first holding module can, for example, be slid onto the base module and moved along the guide elements to a freely selectable position along the base module. It is also conceivable, in principle, to clip the first holding module onto the base module at a freely selectable position. Subsequent repositioning after clipping is not precluded.The guide elements of the base module can be geometrically aligned with a guide contour of guide sections of the first holding module, enabling positive-locking guidance of the first holding module along the base module. The guide elements can, for example, be designed as guide grooves, and a guide contour of the first holding module can engage in such a guide groove in a pin-like, dovetail-like, or mushroom-like manner. As will be explained in more detail below, it is particularly conceivable that the guide elements can be designed as a step on an outer contour of the base module that can be gripped by the first holding module. In principle, the base module can also have guide elements for realizing non-linear guidance of the first holding module along the base module, for example, in the form of cam guides that allow relative displacement of the first holding module along the base module in more than one spatial direction.

[0010] According to one embodiment, the guide elements can form the first connecting elements or at least a part of the first connecting elements. This allows the guide elements to perform a dual function for connecting and guiding the first holding module, resulting in a compact and simple design for the holding device. The guide elements of the base module and the guide sections of the first holding module can, for example, interlock in a form-fit and force-fit manner, so that the first holding module is securely held to the base module. In particular, it is conceivable that the first holding module can only be moved along the base module after a predefined minimum force has been applied by a user, for example, by creating an interference fit between the guide elements and the guide sections or by generating a spring-like preload on the guide sections relative to the guide elements.Accordingly, the first holding module can be self-retainingly arranged on the base module until the predefined minimum force is exceeded, at which point the first holding module can be displaced along the base module. Alternatively or additionally, it is conceivable, for example, to provide locking structures on the guide elements and corresponding counter-locking structures on the first holding module, by means of which the first holding module can be locked in place at various positions along the guide elements.

[0011] According to one embodiment, the counter bearing can be fixedly arranged on the base module, for example by forming the counter bearing integrally with the base module or by connecting it to the base module via fasteners, either detachably or permanently. This allows for a simpler design of the mounting device.

[0012] According to one embodiment, the counter bearing can be designed as a second holding module that can be fixed to the base module at a variable position selectable by the user. This further increases the modularity and flexibility of the mounting device, allowing it to be adapted even more versatilely and precisely to the electrical component being mounted.

[0013] The user can arrange the first and second holding modules even more freely on the base module and, for example, has further scope to arrange differently shaped or differently dimensioned electrical components on the holding device when the first and second holding modules have differently designed receiving sections to form the receiving space.The second holding module can have at least one of the features described above for the first holding module, for example, being guided in a spatial direction by guide elements formed on the base module and being fixable at a variable position, being slid onto the base module and being movable along the guide elements to a freely selectable position along the base module or being clipped on at a freely selectable position, having guide sections geometrically matched to the guide elements of the base module and / or being set up for a self-holding arrangement on the base module by means of a form-fit and / or force-fit connection with the guide elements.

[0014] According to one embodiment, the second holding module can have second connecting elements via which it can be connected to the first connecting elements on the base module. This allows the second holding module to be reliably connected to the base module. The second connecting elements can, for example, be formed by guide sections of the second holding module that interact positively and / or non-positively with the guide elements of the base module, thereby enabling a secure arrangement of the second holding module on the base module.

[0015] According to one embodiment, the guide elements can be designed as steps on opposite sides of the base module, with the second connecting elements of the first and / or second holding module being designed as fastening tabs that engage the steps. The steps provide a simple guide along which the first and / or second holding module can be guided reliably and intuitively. The step can also be referred to as a shoulder or shoulder and can be formed by a recess on a side surface of the base module. The side surface of the base module can form part of its outer contour. The steps create a guide and fastening edge that can be engaged by the fastening tabs, allowing the first and / or second holding module to be guided securely along the base module and fixed to it.The mounting tabs can, for example, have a stepped projection that rests against a step surface of the respective step and slides along it. This stepped projection can form a sliding surface, facilitating the movement of the first and / or second mounting module along the base module. The mounting tabs can be made spring-elastic, for example, through appropriate material selection and shaping, to allow for preloading of the mounting tabs against the steps. This allows the first and / or second mounting module to be self-retainingly fixed to the base module until a predefined minimum force applied by the user causes the first and / or second mounting module to shift along the base module.The fastening tabs of the first and / or second holding module can be arranged on opposite sides of the first and / or second holding module in order to grip the steps arranged on opposite sides of the base module.

[0016] According to one embodiment, the first and / or second holding module can have a release element for separating the respective holding module from the base module in a second spatial direction that differs from the first. This allows the first and / or second holding module to be easily detached directly from the base module without having to, for example, slide it along the base module. For instance, the second connecting elements of the respective holding module, which can be designed as fastening tabs, can have a tool receptacle for prying the second connecting element out of engagement with a first connecting element of the base module. The tool receptacle can, for example, be designed as a pocket into which the tip of a screwdriver can be inserted, so that leverage can be exerted on the second connecting element with the screwdriver.

[0017] According to one embodiment, the first and / or second holding module can be fixed at discrete, spaced-apart detent positions via a toothed connection between the first and / or second holding module and the base module. This allows the first and / or second holding module to be fixed to the base module with particular reliability and precision, the toothed connection securing the first and / or second holding module against unintentional displacement. The toothed connection can, in particular, create a detent connection that enables a positive-locking and force-fit fixing of the first and / or second holding module to the base module. The base module can, for example, have pocket-shaped detent tooth receptacles into which at least one elastic detent tooth of the first and / or second holding module can engage in a detent-like manner.The elastic locking tooth can be displaced between the pocket-shaped locking tooth receptacles by a force applied by the user to the respective holding module and holds the respective holding module securely in the selected position after the displacement force is removed.

[0018] According to one embodiment, the first and / or second holding module can be fixed relative to the base module in the second and third spatial directions via the guide elements, and in the first spatial direction via the toothing. This allows the first and / or second holding module to be securely and precisely attached to the base module in three dimensions. For example, the guide elements, designed as steps that can be gripped by mounting tabs, can predefine the height and width positions of the respective holding module on the base module, while the user can define the length position of the respective holding module via the freely selectable detent position on the toothing.

[0019] According to one embodiment, the tooth spacing of the locking mechanism can be adapted to the pitch of the electrical component being mounted. This allows the position of the first and / or second holding module to be very precisely aligned with the dimensions of the electrical component, thus reliably ensuring a secure hold of the component in the mounting device. A tooth spacing can refer to the average distance between successive locking teeth. A pitch can, for example, be the distance between adjacent electrical terminals of the component.Often, the overall extent, for example a width, of an electrical component corresponds to a multiple of such a pitch distance, so that a receiving space with a distance between receiving sections of the first and / or second holding module, precisely adapted to the overall extent of the electrical component, can be set via a tooth spacing matched to this.

[0020] According to one embodiment, the base module can have a first gear arrangement with a first gear spacing and a second gear arrangement with a second gear spacing. A gear spacing can refer to an average distance between successive detent tooth receptacles. The first retaining module can be configured to engage with at least one elastic detent tooth in the first gear arrangement or in the second gear arrangement. The second retaining module can be configured to engage with at least one elastic detent tooth in the first gear arrangement or in the second gear arrangement.Accordingly, depending on which gear arrangement is to be used for the respective holding module, a first or second variant of the first holding module and / or a first or second variant of the second holding module can be arranged on the base module and defined by the gearing. The second gear spacing of the second gear arrangement can, for example, be a smaller gear spacing than the first gear spacing of the first gear arrangement. The selectable gear arrangement with a first or second gear spacing further increases the range of available detent positions and enables very precise alignment of the first holding module and the counter bearing relative to each other.The first and second gear arrangements can, for example, have pocket-shaped locking tooth receptacles arranged in a row, into which at least one elastic locking tooth of the first and / or second holding module can engage. The locking tooth receptacles can also be arranged in two rows, and the first and / or second holding module can have two elastic locking teeth designed to engage the locking tooth receptacles, thus enabling a more stable locking of the respective holding module to the base module.In the case of double-row locking tooth receptacles of the first and second gear arrangements, it can be provided, for example, that the double-row locking tooth receptacles of the first gear arrangement are arranged essentially centrally next to each other on the base module, and that the double-row locking tooth receptacles of the second gear arrangement flank the locking tooth receptacles of the first gear arrangement on their outer sides, i.e., are spaced apart from each other by the locking tooth receptacles of the first gear arrangement. This ensures a symmetrical positioning of the pocket-shaped locking tooth receptacles, which facilitates the arrangement and locking of the first retaining module and / or the second retaining module on the base module.

[0021] According to one embodiment, the first retaining module can have a locking tooth for engaging with the first gear assembly. Alternatively or additionally, the second retaining module can have a locking tooth for engaging with the second gear assembly. This allows for a stable locking of the first retaining module in the first gear assembly and / or the second retaining module in the second gear assembly. The locking tooth can, for example, be an elastic locking tooth. The locking tooth of the first retaining module can be designed to match the first gear assembly, enabling a clear assignment of the locking tooth of the first retaining module to the first gear assembly. The locking tooth of the second retaining module can be designed to match the second gear assembly, enabling a clear assignment of the locking tooth of the second retaining module to the second gear assembly.

[0022] According to a further development, the first holding module can have two locking teeth spaced apart by a first locking tooth spacing, while the base module has two first gear arrangements spaced apart by an arrangement spacing corresponding to the first locking tooth spacing. This allows for a geometrically unambiguous assignment of the locking teeth of the first holding module to the first gear arrangements. In other words, the locking teeth of the first holding module are designed to match the two first gear arrangements by virtue of the matching spacing between the locking teeth and the gear arrangements.

[0023] According to a further development, the second retaining module can have two locking teeth spaced apart by a second locking tooth spacing that differs from the first locking tooth spacing, wherein the base module has two second gear arrangements spaced apart by an arrangement spacing corresponding to the second locking tooth spacing. This allows for a geometrically unambiguous assignment of the locking teeth of the second retaining module to the second gear arrangements. In other words, the locking teeth of the second retaining module are designed to match the two second gear arrangements by virtue of the matching spacing between the locking teeth and the gear arrangements.

[0024] According to one embodiment, the first and second holding modules can have symmetrically designed receiving sections to form the receiving space. This allows for particularly simple and intuitive handling, as the holding modules can be arranged on the base module independently of a predefined orientation. Such an embodiment can be particularly suitable for mounting electrical components that have a substantially symmetrical outer contour and do not require differently designed receiving sections on different sides.

[0025] According to one embodiment, the first and second holding modules can have asymmetrically designed receiving sections to form the receiving space. This allows asymmetrically contoured electrical components and / or electrical components requiring a specific orientation relative to the base module to be arranged in the receiving space. According to another embodiment, the first and / or second holding module can have a coding element to indicate their mounting orientation on the base module. The coding element, for example, an optical marker or a positive-locking guide element, ensures the correct arrangement and orientation of the first and second holding modules on the base module.

[0026] According to one embodiment, the electrical component can be clamped in the receiving space between the first holding module and the counter bearing. This ensures secure retention of the electrical component in the receiving space. For example, the first holding module can be positioned on the counter bearing via the aforementioned toothing such that an electrical component positioned between the first holding module and the counter bearing is pressed against the counter bearing under preload by the first holding module. If the counter bearing is designed as a second holding module, the positioning can also be achieved by the second holding module in the direction of the first holding module or by positioning both holding modules towards each other.

[0027] According to one embodiment, the first holding module and / or the counter bearing can have a fixing element for securing the electrical component in the receiving space. This ensures that the electrical component is securely held in the holding device. Such a fixing element can, for example, be a detent unit such as an elastic detent hook that can engage a detent edge of the electrical component. However, other mechanical fixing elements, such as tension springs or screw holes, are also conceivable. The fixing element can be designed, in particular, for tool-free fixing of the electrical component, as is the case, for example, with a detent unit. The fixing element can also be designed, in particular, for non-destructive re-fixing of the electrical component.

[0028] According to one embodiment, the mounting device can be designed to secure a distribution module as an electrical component. Distribution modules can have very different external geometries depending on their intended use and their specific electrical distribution arrangement, making a flexibly adjustable mounting device advantageous for such electrical components. The simple design and ease of use of the described mounting device reduce the time and cost involved in installing distribution modules.

[0029] According to one embodiment, the base module can have fastening elements with which the mounting device can be attached to the object. This allows the base module to be securely fixed to a designated mounting surface. The fastening elements can be designed, for example, as screw holes for passing screws, as snap-in elements, or a combination thereof.

[0030] The invention also relates to a set comprising a base module and a first holding module for forming a mounting device according to one of the features described above. The proposed set also offers the advantages described above of simple and flexible attachment of an electrical component to an object. In particular, the set can further comprise a second holding module for forming a counter-bearing.

[0031] In general, in connection with this application, the words "ein / eine" are not to be understood as numerals, unless expressly defined otherwise, but as indefinite articles with the meaning of "at least one".

[0032] The invention allows for various embodiments and is explained in more detail below with reference to exemplary embodiments and the accompanying drawings. These show, in schematic form: Fig. 1 - a mounting device with a first and a second mounting module according to a first embodiment in a perspective side view; Fig. 2 - a mounting device with a first and a second mounting module according to a second embodiment and an electrical component in a perspective side view; Fig. 3 - the mounting device according to Fig. 1 in an exploded view; Fig. 4 - the first holding module according to the first embodiment with a first locking tooth variant; Fig. 5 - the first holding module according to the second embodiment with a second locking tooth variant; Fig. 6 - the mounting device according to Fig. 1 in a supervisory role; Fig. 7 - the mounting device according to Fig. 6 in a sectional view along the in Fig. 6 shown section line BB; Fig. 8 - a basic module of the mounting device according to Fig. 1 in a supervisory role; Fig. 9 - the basic module according to Fig. 8 in a sectional view along the in Fig. Section line CC shown in section 8.

[0033] Fig. Figure 1 shows a mounting device 1 for attaching, for example, a Fig. The electrical component 2 shown is attached to an object not shown in detail, such as an electrical installation unit. The mounting device 1 has a base module 3 on which a first mounting module 5 and a second mounting module 8 forming a counter bearing 7 are arranged. A receiving space 9 is formed between the first mounting module 5 and the second mounting module 8, in which the electrical component 2 to be attached, such as in the following, is placed. Fig. 2 shown is at least partially recognizable and can be fixed to the mounting device 1.

[0034] The base module 3 has first connecting elements 4, which simultaneously form guide elements 10 of the base module 3. The first holding module 5 and the second holding module 8 can be guided along the base module 3 in a first spatial direction x and fixed at a variable position on the base module 3, selectable by the user. This provides a modular mounting device 1 with flexible application possibilities and high adaptability to the electrical components 2 to be mounted. Alternatively, the counter bearing 7 can also be designed as a counter bearing 7 fixedly connected to the base module 3 instead of a movable second holding module 8. The first connecting elements 4, designed as guide elements 10, enable safe and intuitive handling and positioning of the first holding module 5 and / or the second holding module 8.The guide elements 10 form a linear guide for the first holding module 5 and / or the second holding module 8, which can be slid laterally onto the base module 3 and moved along the guide elements 10. Alternatively or additionally, the first holding module 5 and / or the second holding module 8 can be clipped onto the base module 3 at any position. Subsequent repositioning after clipping is not excluded.

[0035] According to the in Fig. In the embodiment shown in Figure 1, the first connecting elements 4 are designed as steps on opposite sides 11a, 11b of the base module 3. The first retaining module 5 and the second retaining module 8 each have second connecting elements 6 for connecting the first retaining module 5 and the second retaining module 8 to the base module 3 via the first connecting elements 4. According to the illustrated embodiment, the second connecting elements 6 are designed as fastening tabs that engage the first connecting elements 4, which are designed as steps. By means of the fastening tabs, the first retaining module 5 and the second retaining module 8 can be fixed to the base module 3 in a form-fit and force-fit manner. The fastening tabs can, in particular, be designed to be spring-elastic in order to generate a preload in the direction of the steps.This allows the first holding module 5 and the second holding module 8 to be positioned self-retainingly on the base module 3 and, in particular, to only be moved along the base module 3 by the application of a predefined minimum force by a user. The first connecting elements 4 and the fastening tabs forming the guide elements 10 can be geometrically coordinated. Due to the reduced degrees of freedom of the first holding module 5 and the second holding module 8 resulting from the connection between the first connecting elements 4 and the second connecting elements 6, these are fixed relative to the base module 3 in a second spatial direction z and in a third spatial direction y, but movable along the first spatial direction x. As shown in the further... Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 to Fig. As explained in more detail in section 9, the first holding module 5 and the second holding module 8, according to the illustrated embodiments, can be fixed at discrete, spaced-apart detent positions via a toothing 13 acting between the respective holding module 5, 8 and the base module 3, so that a user-selectable detent position in the first spatial direction x can be defined via the toothing 13. For this purpose, the base module 3 can have detent tooth receptacles 13a into which at least one, for example, in the Fig. 4 and Fig. 5 visible elastic locking tooth 13b of the first holding module 5 and / or of the second holding module 8 can engage in a locking manner.

[0036] The first holding module 5 and the second holding module 8 each have a release element 12 for separating the respective holding module 5, 8 from the base module 3 in the second spatial direction z, so that the first holding module 5 and / or the second holding module 8 can be directly detached from the base module 3 without having to move them along the first spatial direction x. According to the illustrated embodiment, the release elements 12 are designed as tool receptacles in the form of pockets into which, for example, the tip of a screwdriver can engage and lever the second connecting elements 6, designed as fastening tabs, out of engagement with the first connecting elements 4, designed as steps.

[0037] As in Fig. As shown in Figure 1, the base module has 3 fastening elements 16 with which the mounting device 1 can be attached to an object. According to the illustrated embodiment, the fastening elements 16 are designed as screw holes for receiving fastening screws.

[0038] In Fig. As can be seen from Figure 1, the first holding module 5 and the second holding module 8 have asymmetrically designed receiving sections 14 to form the receiving space 9, in order to accommodate suitable external geometries of electrical components 2. In particular, a coding element (not shown in detail) may be provided to indicate the mounting orientation of the respective holding module 5, 8 on the base module 3.

[0039] In contrast, in Fig. Figure 2 shows an embodiment in which the first holding module 5 and the second holding module 8 have symmetrically designed receiving sections 14 for forming the receiving space 9. In this embodiment, the holding modules 5, 8 can be arranged essentially freely on the base module 3. As shown in Fig. As shown in Figure 2, an electrical component 2, here in the form of a distribution module 2a, can be arranged in the receiving space 9 and attached to an object using the mounting device 1. The electrical component 2 can be positioned as shown in Figure 2. Fig. 2. The electrical component 2 is evidently projecting beyond the receiving space 9 formed between the receiving sections 14 of the first holding module 5 and the second holding module 8 into the vicinity of the holding device 9, so that the electrical component 2 is partially contained within the receiving space 9. The electrical component 2 can be clamped, in particular, within the receiving space 9 between the first holding module 5 and the second holding module 8, for example, by moving the first holding module 5 and the second holding module 8 relative to each other in such a way that a clamping force can be exerted from the receiving sections 14 onto the electrical component 2 in the direction of the other holding module 5, 8 acting as a counter-bearing 7.

[0040] What's next in Fig. As can be seen in Figure 2, the electrical component 2 can have a defined pitch a. T have, where the division distance a Ta distance between adjacent electrical terminals of electrical component 2. It can be advantageous if a gear spacing a Z the toothing 13 to the pitch distance a T is adapted, as this allows the position of the first holding module 5 and the second holding module 8, and thus the resulting receiving space 9, to be precisely adapted to the dimensions of the electrical component 2.

[0041] The first holding module 5 and the second holding module 8 each have a fixing element 15 for fixing the electrical component 2 in the receiving space 9 to ensure a secure hold of the electrical component 2 on the holding device 1. According to the illustrated embodiment, the fixing element 15 is designed as an elastic locking hook that can engage behind a locking edge of the electrical component 2, thereby providing a non-destructive and tool-free actuating fixing option.

[0042] Fig. Figure 3 shows the mounting device 1 according to Fig. 1 in an exploded view. At the same time illustrates Fig. 3 A set 20 comprising a base module 3, a first holding module 5, and a second holding module 8 for forming a holding device 1 according to a further aspect of the invention. It is evident that the holding device 1 has a simple structure and is easy and intuitive to use. The base module 3 is designed as a mounting plate, which can be attached, for example, via the fastening elements 16 to a mounting surface of an object and serves as a support for the first holding module 5 and the second holding module 8.

[0043] As already explained, the first holding module 5 and the second holding module 8, according to the illustrated embodiments, can be fixed at discrete, spaced-apart detent positions via a toothing 13 acting between the respective holding module 5, 8 and the base module 3. This allows the holding modules 5, 8 to be positioned on the base module 3 with particular precision and security and to be locked in the selected position. The toothing 13 can be considered a detent connection for creating a force-fit and form-fit connection between the holding modules 5, 8 and the base module 3. To create the toothing 13, the base module 3 can have pocket-shaped detent tooth receptacles 13a into which elastic detent teeth 13b of the holding modules 5, 8, as are found, for example, in the Fig. 4 and Fig. 5 are visible, can intervene continuously.

[0044] As in Fig. As can be seen from Figure 3, the basic module 3 can have a first gear arrangement 13' and a second gear arrangement 13". Furthermore, as can be seen in conjunction with the Fig. 8 and Fig. As can be seen in Figure 9, the first gear arrangement 13' has a first gear spacing a Z1 and the second gear arrangement 13" has a second gear spacing a Z2 This allows for even freer and more precise positioning of the first holding module 5 and the second holding module 8 on the base module 3. For this purpose, first holding modules 5 and / or second holding modules 8 can be provided with different locking tooth variants, as shown by the Fig. 4 and Fig. 5 is explained in more detail below. The first gear arrangement 13' is formed by double rows of centrally arranged, adjacent locking tooth receptacles 13a. The second gear arrangement 13" is formed by rows of locking tooth receptacles 13a flanking the first gear arrangement 13' on the outside. Such an arrangement of the first gear arrangement 13' and the second gear arrangement 13" enables symmetrical gearing 13 of the retaining modules 5, 8 with the base module 3.

[0045] Fig. Figure 4 shows a first holding module 5 according to the first embodiment with asymmetrically designed receiving sections 14. Fig. As shown in Figure 4, the first holding module 5, according to a first locking tooth variant, has two centrally arranged, and in particular elastically designed, locking teeth 13b. These are designed to engage with the centrally arranged double-row locking tooth receptacles 13a of the first gear arrangement 13' of the base module 3 and can thus fix and lock the first holding module 5 onto the base module 3 at a user-selectable position in the first spatial direction x. As shown in Fig. As can be seen in section 4, the two locking teeth 13b are spaced apart from each other by a first locking tooth spacing 13c. The first locking tooth spacing 13c can be described in Fig. The spacing 13'c shown in Figure 8 between the first two gear arrangements 13' of the basic module 3 corresponds to this. This allows for a unique geometric assignment of the detent teeth 13b to the first gear arrangements 13' of the basic module 3. Fig. Figure 5 shows a first holding module 5 according to the second embodiment with symmetrically designed receiving sections 14. Fig. As can be seen in Figure 5, the first retaining module 5, according to a second locking tooth variant, has two locking teeth 13b, which are designed to be particularly elastic and are spaced further apart than the locking teeth 13b according to the first locking tooth variant. The locking teeth 13b are designed to engage with the externally arranged locking tooth receptacles 13a of the second gear arrangement 13'' of the base module 3 and can thus fix and lock the first retaining module 5 onto the base module 3 at a user-selectable position in the first spatial direction x. By providing at least two elastic locking teeth 13b on the first retaining module 5, the first retaining module 5 can be locked onto the base module 3 particularly securely and stably. As shown in Fig. As can be seen in section 5, the two locking teeth 13b are spaced apart by a second locking tooth spacing 13d, which differs from the first locking tooth spacing 13c and is larger in this case. The second locking tooth spacing 13d can be described as follows: Fig. The spacing 13''d shown in Figure 8 between the two second gear arrangements 13'' of the basic module 3 corresponds to this. This allows a unique geometric assignment of the detent teeth 13b to the second gear arrangements 13' of the basic module 3.

[0046] In principle, a second holding module 8 can be constructed analogously to the first holding module 5. In particular, the second holding module 8 can, for example, have two detent teeth 13b with a second detent tooth spacing 13d, where the second detent tooth spacing 13d corresponds to the arrangement distance 13''d between the two second gear arrangements 13'' of the base module 3. This allows the detent teeth 13b of the first holding module 5 and the second holding module 8 to be differentiated from one another and assigned to the respective first and second gear arrangements 13', 13''.

[0047] Furthermore, in the Fig. 4 and Fig. 5 can be seen that the second connecting elements 6, designed as fastening tabs, have step-shaped projections 17 which rest against a respective step surface of the first connecting elements 4, designed as steps, and can slide along them.

[0048] In principle, the second holding module 8 can also be used in accordance with at least one of the above in connection with the Fig. 4 and Fig. The 5 explained features of the first holding module 5 must be implemented.

[0049] The Fig. 6 and Fig. Figure 7 shows again the mounting device 1 according to the first embodiment in a top view and in a sectional view. The top view further illustrates the asymmetrical design of the receiving sections 14. In addition, the Fig. 6 and Fig. Figure 7 illustrates the formation of the receiving space 9 between the receiving sections 14 of the first holding module 5 and the second holding module 8. As shown by the toothing 13 in Fig. As can be seen in Figure 7, according to the illustrated embodiment, a first holding module 5 and a second holding module 8 with the first locking tooth variant were selected, in which the centrally adjacent elastic locking teeth 13b of the holding modules 5, 8 engage in the first tooth arrangement 13' of the base module 3. In principle, it is also conceivable to use a first holding module 5 and a second holding module 8 with the second locking tooth variant, in which the spaced-apart elastic locking teeth 13b of the holding modules 5, 8 engage in the second tooth arrangement 13' of the base module 3, or to combine a first holding module 5 with the first locking tooth variant and a second holding module 8 with the second locking tooth variant, or vice versa.

[0050] The Fig. 8 and Fig. Figure 9 shows again, in isolated views, the basic module 3 of the mounting device 1 in a top view and in a sectional view. The sectional view, in particular, clearly shows that the first gear arrangement 13' has a first gear spacing a. Z1 and the second gear arrangement 13'' a second gear spacing a Z2 has, where the second gear spacing a Z2 is smaller than the first gear spacing a Z1 Thus, the user can freely select the degree of accuracy for the positioning of the first holding module 5 and / or the second holding module 8. Furthermore, in Fig. Figure 8 shows that two first gear arrangements 13' can be provided, which have a first arrangement distance 13'c from each other. The first arrangement distance 13'c can be assigned to a Fig. The first tooth spacing 13c shown in Figure 4 corresponds to the tooth spacing between the teeth 13b of the first retaining module 5. Furthermore, as shown, two second gear arrangements 13'' can be provided, which have a second spacing 13''d from each other. The second spacing 13''d can correspond to a Fig. 5 shown second locking tooth spacing 13d between the locking teeth 13b of the first holding module 5 or of an analogously constructed second holding module 8 correspond.
