Description

Modular housing wall for telecommunications equipment

The invention relates to a modular housing wall for facilities of telecommunications and data technology.

Modular housing walls for telecommunications equipment are already known in various commercially available versions of the prior art. For example, DE 19709460 C2 discloses an open-air housing for accommodating electronics, in particular components of telecommunications and data technology, wherein the electronics are hermetically sealed by a first inner housing, and a second outer housing is arranged in the first inner housing a cavity is formed between the housings, wherein the second outer housing is formed by hollow profiled rails, which are releasably secured to the first inner housing, and the hollow profile rails are formed with fastening means by means of which the hollow profile rails suspended from the inner housing and in the assembled state of outside are arranged inaccessible. A disadvantage of this housing wall described in the prior art is that the structure and shape of the hollow profile rails can not be varied arbitrarily. Rather, a specific outer design of the housing wall is already mandatory given by the hollow profile structure. In addition, the hollow profile rails have a rather complex structure, which is why such housing walls are less advantageous as a simple standard version of a housing wall for telecommunications equipment due to the high production costs. Another disadvantage is the fact that usually the assembly of the housing can not be done without tools.

The invention is therefore based on the technical problem of providing an improved modular housing wall for telecommunications equipment.

The solution of the technical problem results according to the invention by the subjects of claims 1 and 20. Further advantageous embodiments of the invention will become apparent from the dependent claims.

The invention is based on the finding that the use of easy-to-manufacture standard components and fasteners substantially increase the versatility of a modular housing wall. This is achieved according to the invention by proposing a modular housing wall for telecommunication and data technology equipment, comprising at least one cover element for forming a flat wall section and at least one latching rail for fixing the at least one cover element, wherein the at least one cover element at least partially has a U-shaped cross-section with a plurality of latching means and the latching rail notches having fasteners, with which the latching means for hooking the cover on the latching rail into engagement are brought. This simple construction allows cost-effective production of both the cover and the locking rail in almost any variety of variants. The modular housing wall according to the invention can then be used in the same way both in horizontal and in vertical orientation as a wall, floor or ceiling surface, but also as a partition. The locking rail is the supporting element of the modular housing wall system and, inter alia, receives the cover by means of snapping. Preferably, at least one pair of locking rails are fastened to at least one housing profile serving for the support. Depending on the length of the cover elements further locking rails may be required at certain intervals for support. The covering element designed as a panel, for example, serves as a housing wall module designed as a flat surface and, because of its U-shaped contour, can be pushed over the fastening means arranged on the latching rail and latched into the notches located there by means of its latching means. In a preferred embodiment, the cover has no holes or slits, whereby the production of the cover is considerably simplified and almost any length can be made because the profile of the cover can be formed in principle in an endless process (eg as extruded or by way of Rollumformverfahren , oa) and then only has to be cut to the desired length for use as part of the modular housing wall. The latching rail is preferably formed as a stamped part made of sheet metal. However, it is also vorstelibar that they as Kunststofftei! cut from a plate or produced as Spritzten. The dimensioning of the cover and the locking rail is determined by the particular application. The cover element can be produced both from plastic (eg by extrusion) and from metal (eg from a belt by roll forming).

In an advantageous embodiment, the latching means are formed as extending in the longitudinal direction inwardly bent edges. This leads to a particularly simple construction of the cover and allows the use of simple and inexpensive manufacturing process while ensuring a tight fit of the cover on the locking rail in the mounted, i. latched state.

In a further advantageous embodiment, at least one locking means as in Longitudinal outwardly bent edge formed. The U-shaped cover member for mounting at least partially surrounds one of the fastening means, while the outwardly bent edge preferably engages in a notch of an adjacent fastener and is engaged with this. This ensures a particularly stable fixation of the cover on the locking rail without adversely affecting the production cost or the simple structure of the modular housing wall.

In a further advantageous embodiment, the fastening means are arranged in periodically recurring spacing grid on the locking rail. In this way, a plurality of cover elements can be hung flush and in abutment next to each other on the locking rail and arranged so as to form a coherent planar housing wall surface in a simple manner.

In a further advantageous embodiment, the cover elements have a width in the transverse direction, through each of which a plurality of the fastening means can be covered, wherein the locking means of the cover are brought into engagement with one of the notches of at least two different fastening means. The smallest possible cover element according to the invention snaps over only one fastening means of the locking rail. The next possible size, according to this advantageous embodiment, then snaps over two fastening means, etc. The maximum possible cover element snaps over "n" fastening means (Module) is in principle freely selectable and is determined by the surrounding housing and its structural design, whereby a nearly limitless versatility of the modular structure of the housing wall is made possible in a simple manner because the system is modular.

In a further advantageous embodiment, the fastening means are designed as tabs arranged on the latching rail, wherein the notches are respectively arranged at the transition between latching rail and lugs. The indentations are arranged at that end of the tabs, which is not freestanding, but is connected to the locking rail and is opposite to a freestanding end of the tabs. For assembly, one of the cover elements can then be pushed over one of the tabs due to its U-shaped contour and with the aid of its locking means in engage one of the notches on the base of the tab. The cover element is preferably "clipped" onto the fastening means of the latching rail designed as tabs without tools, which considerably simplifies the assembly of the modular housing wall.

In a further advantageous embodiment, the tabs have an at least partially rounded outline at their freestanding end. This facilitates the assembly of the modular housing wall enormously, since due to the at least partially rounded outline, the U-shaped cover can be pushed very easily from above over the fastening means designed as tabs, by means of its locking means in each case one of the notches on the base of the tabs for education a stable connection to lock.

In a further advantageous embodiment, at least one U-shaped filling profile is provided and the locking rail has at least one support tab, wherein the filling profile is arranged next to the at least one cover on the locking rail and is brought into positive engagement with the support tab for attachment. The filling profile is preferably clamped without tools next to a cover and this locks against the relevant fastener on the locking rail. The filling profile preferably does not have any perforations or slits, which considerably simplifies the production and allows virtually any length, since the profile can in principle be shaped in an endless process (eg as an extruded profile or in a roll forming process, above) and then for use as a component the modular housing wall only needs to be cut to the desired length. The top of the filling profile preferably closes in the assembled state - but not necessarily - flush with the top of the cover and then results in a nearly flat surface, only interrupted by possibly existing curves at the joints. Lower inwardly directed bends of the side surfaces of the filling profile preferably clamp the filling profile slightly below the locking means of the cover firmly, which in particular provides increased security against unintentional release of the filling profile at vibration and vibration. The bias of the lateral legs of the U-shaped filling profile generated thereby prevents it from leaving its intended end position due to vibrations or shocks. Furthermore, the filling profile locks the respectively adjacent cover against unlocking and still increases the contact pressure between the cover and locking rail. The linear contact surfaces between filling profile and adjacent cover provide at least for a simple sealing effect against dust and water spray and an electrical ground contact with electrically conductive surface. The dismantling of the Filling profiles is then preferably also without tools, especially if the structure of the housing allows that the filling profile can be pushed from its underside with a finger from its positive engagement with the support tab. Otherwise, it may be advisable to use, for example, a simple hook-shaped object (eg, a sturdy, curved paperclip) to help raise the fill profile from one side of its top to grab it.

In a further advantageous embodiment, the filling profile has a plurality of latching means and the at least one support tab has notches at its transition to the latching rail and / or an at least partially rounded outline at its freestanding end. For assembly, the filling profile can then be pushed over the support plate due to its U-shaped contour and engage with the aid of its locking means in each case one of the notches on the base of the support bracket. The at least partially rounded outline of the support tabs on their freestanding end facilitates the assembly of the modular housing wall enormously, since due to this rounded outline the U -shaped filling profile can be easily pushed from above the support tab to lock by means of its locking means in one of the indentations - if any - on the base of the support tabs to form a stable connection or clamp the filling profile by its bias on the support bracket.

In a further advantageous embodiment, in each case one Füllprofäi is arranged between two cover elements. The locking rail has fastening center! for receiving the cover elements and between them supporting straps for supporting the filling profiles. These contours alternate in an almost freely determinable mounting grid (module) on the locking rail. The mounting grid is determined only by the surrounding housing and its structural design. The integer module is composed of the width of the smallest cover element plus the width of a filling profile. For example, for a fictitious module "1" (assuming some exemplary numerical values for the cover element and the filling profile), the following width results: module "1" = 1 x cover element "1" + 1 x filling profile = 35 mm + 15 mm = 50 mm

For larger cover elements, the calculation is analog, with the module always being an integer. Thus, for example, the following width results for the fictitious module "5": module "5" = 1 x cover element "5" + 1 x filling profile = 235 mm + 15 mm = 250 mm From this it can be seen that in the example given, the module chosen is based on a mounting grid of 50 mm, the filling profile here always having a constant width of, for example, 15 mm. The module is thus determining the position of the fastening elements for fixing the cover and the support tabs for fixing the filling profiles on the locking rail. To assemble the filling profile is then pressed with little pressure without tools between two cover elements to the stop on the support tabs of the locking rail. If a filling profile is arranged in each case between two covering elements, the dismantling of covering elements can then likewise be carried out without tools, if the two adjacent filling profiles are removed beforehand and then the covering element is unlocked via the fastening element, for example with the fingers. Otherwise, it is also sufficient to use a simple hook-shaped object to help and lift the filling profile from its top to one side something to then grab it. This is particularly advantageous for retrofits of cover elements, eg. B. when designed as a blanking cover is to be exchanged for a ausgestaltetes example with cable duct panel. This can be done quickly and directly by and at the user without having to move the remaining parts of the modular housing wall. Also internals do not hinder this process, provided that a small minimum distance between cover and internals is respected.

In a further advantageous embodiment, at least the surface of the modular housing wall has electrically conductive properties. This offers the advantage that the modular housing wall can then also be used for applications with special requirements for electromagnetic compatibility (EMC), since parts which are to produce EMC protection must be electrically conductive (eg made of metal ) and or at least have to have a conductive coating. For example, in cable distributors or electrical cabinets are often additional requirements in terms of electromagnetic compatibility (EMC) to meet. For example, housing walls used, for example, for a telecom cabinet are typically required to be provided with EMC protection, i. an EMI-compliant shielding, to provide that prevents, for example, by switching operations in the cabinet caused interference signals can escape through the housing wall from the cabinet.

In a further advantageous embodiment, at intervals between at least two of the cover elements and / or between the at least one cover element and at least one housing profile and / or between the at least one cover and the at least one filling profile and / or between the at least one filling profile and the at least one housing profile each provided at least one seal. The seal increases in particular the tightness of the modular housing wall against water pressing in from the outside or penetrating moisture, which is why the modular housing wall is then particularly suitable for outdoor applications, ie outdoors.

In a further advantageous embodiment, the seal has an inner core made of an elastic material, which is enveloped on the circumference by a conductive fabric structure. Such a seal not only enhances the tightness of the modular housing wall against pressurized water or moisture, but also serves to meet additional electromagnetic compatibility (EMC) requirements of the modular housing, i. At the same time, the seal is also EMC-tight in the frequency range specified for this seal. Accordingly, this embodiment is particularly suitable for EMC-tight applications in the outdoor area. The inner core preferably consists of a soft elastomer core, z. As foam, neoprene, silicone, PVC, an ethylene-propylene elastomer (EPDM) or other plastic with elastic properties. He has for the case of use between two cover preferably a square, more preferably a rectangular cross-section. However, it is also conceivable that the inner core is formed as filled with metal or carbon and thus provided with electrical conductivity elastomer. The conductive fabric is preferably formed from a metal mesh or braid. But it is also conceivable that the fabric structure metaiibeschichtete threads, z. B. silvered nylon threads, including.

In a further advantageous embodiment, the lateral limbs of the U-shaped cross section of the at least one filling profile and / or the at least one covering element are concave. Although already achieved by the outer edges of the filling profile, which contact an adjacent cover, a simple sealing effect, but also serve the concave side surfaces as a space for receiving additional seals, if this is necessary in certain cases.

In a further advantageous embodiment, the lateral limbs of the U-shaped cover member and / or the U-shaped filling profile for the production of Abschirmfederelementen in periodically recurring in the longitudinal direction spacing grid are slotted transversely. Due to the resulting shortened line-shaped, form-fitting Contact surfaces of the cover against the adjacent filling profiles and / or against each other creates an improved protection against penetrating dust or spray, as well as an electrical ground contact with a conductive surface.

In a further advantageous embodiment, the width of the shielding spring elements in the longitudinal direction and the gap length of the slots in each case λ / 10 of the highest frequency to be shielded. In this case, λ corresponds to the wavelength of the electromagnetic waves to be shielded. By virtue of the individual shielding spring elements generated by means of the slots, which contact the adjacent covering elements, an improved EMC protection is achieved. The width of the individual shielding spring elements is determined by the frequency range to be shielded and the upper damping amount, the width preferably having to be smaller than λ / 10 of the highest frequency.

In a further advantageous embodiment, the at least one covering element and / or the at least one filling profile has at least one area which is perforated at regular intervals. Thus, the modular housing wall formed therefrom is also e.g. suitable for use as an air-permeable partition, as e.g. is often required in ventilated or air-conditioned enclosures or cabinets where e.g. separate access or access rights must be established. The cover and / or the filling profile can be perforated with any hole pattern.

In a further advantageous embodiment, the at least one cover element and / or the at least one filling profile is at least partially formed from a wire mesh or mesh. This embodiment also allows the use of the modular housing wall as an air-permeable partition.

In a further advantageous embodiment, the at least one cover element and / or the at least one filling profile has openings for receiving cable bushings. In combination with closed cover elements and / or filling profiles, this makes it easy and inexpensive to produce virtually any combination of user-specific housing walls, which can be used, for example, as wall, floor or ceiling coverings or partitions. The openings serve to receive and fix a cable bushing and a cable to be performed in this way through the modular housing wall. It is also conceivable that the cable bushing used for this purpose has simultaneously electrically conductive properties and thus even without additional shielding elements to be attached as EMC density Shielding is able to serve. For this purpose, for example, an electrically conductive additional material may be introduced into the elastic base material of the cable feedthrough, as a result of which the cable feedthrough has electrically conductive properties. In this case, then at least the edge of the opening in the modular housing wall, ie in the cover or in the filling profile, preferably formed metallic and the cable feedthrough with this then preferably directly and without further aids or accessories in engagement. It is also conceivable that the user can even remove individual closed cover elements and / or filling profiles from the modular housing wall, if necessary, to subsequently introduce openings, ie openings for receiving cable bushings, according to the individual requirements, which in most cases in a simple manner common drilling or punching tools is possible. In this way, it is then not necessary to determine the shape and diameter of the opening in the modular housing wall, in which a specific cable feedthrough is to be positioned, already during the production process of the modular housing wall. Rather, this can be done only during or after installation on site, which increases the versatility of the modular housing wall considerably. The shape of the opening for the cable bushing can then also be almost arbitrary.

The invention will be explained in more detail below with reference to a preferred embodiment. In the accompanying drawings show

Embodiment of a modular housing wall.

Fig. 1 shows schematically a perspective side view of the basic elements of a modular housing wall 1. Separately, ie in the unassembled state, shown are a cover 2 to form a flat wall portion, a filling profile 15 and a locking rail 10 for fixing the cover 2 and the filling profile 15. The cover member 2 partially has a U-shaped cross-section with a plurality of locking means 5, which are formed as extending in the longitudinal direction, inwardly bent edges. At an angle to its base 3, angled bends of the cover element 2 form the lateral limbs 16a of its U-shaped cross-sectional profile. The locking rail 10 comprises fastening means, which are designed as tabs 11 and have notches 13a, with which the locking means 5 for mounting the cover 2 on the locking rail 10 can be brought into engagement. The notches 13 a are each arranged at the transition between locking rail 10 and tabs 11. The tabs 11 have at their free-standing end an at least partially rounded outline 12a. The locking rail 10 also has support tabs 18, with which the filling profile 15 for fastening both positive and preferably non-positively engageable and can be arranged on the locking rail 10. The support tabs 18 have a partially rounded outline 12b at their freestanding end 19. The cover element 2 designed as a panel serves as a housing wall module designed as a flat surface and, because of its U-shaped contour, can slide over the tabs 11 arranged on the latching rail 10 and engage in the notches 13a located there by means of its latching means 5. The filling profile 15 has lower inwardly directed bends 17 of its side surfaces 16b, with which at the support tabs 18, a clamping action can be achieved. The tabs 11 and the support tabs 18 are arranged in periodically recurring spacing grid on the locking rail 10. Between two tabs 11 for receiving the cover 2, a support tab 18 for supporting the filling profiles 15 is arranged in each case. These contours change into an almost freely determinable mounting grid, the so-called module 7, on the locking rail 10 from. The module 7 of the modular housing wall 1 determines the position of the tabs 11 for fastening the cover element 2 and the support tabs 18 for fastening the filling profiles 15 on the latching rail 10. The module 7 corresponds to the distance from center to center of two adjacent tabs 11. The center distance between one of the tabs 11 and the respective adjacent support tab 18 corresponds to half of the module. 8

FIG. 2 schematically shows the cross-sectional views of differently wide cover elements 2, which correspond to different panel sizes. However, the dimensioning of the latching means 5 and the lateral legs 16a of the individual cover elements 2 does not differ. The cover elements 2 have, in their transverse direction, a width B through which either only one of the tabs 11 or a respective plurality of tabs 11 can be covered on the latching rail 10 (see FIG. 1), in the latter case - i.e. for a cover element of the order of magnitude (n> 1), which covers a plurality of tabs 11 - the latching means 5 of the cover elements 2 can be brought into engagement with one of the notches 13a of two different tabs 11. It therefore has the order of magnitude "1." The next possible size then snaps over two lugs 11 and thus has the order of magnitude "2", etc. The largest possible cover element 2 snaps over "N" tabs 11. If b corresponds to the width of the smallest cover element 2 of the order of magnitude "1", then the width B of the cover element 2 which can be latched over "n" tabs 11 results as follows:

B = (n-1) x module + b

This results, for example, for a cover element 2 of the order of n = 5 and a module = 50 mm and a smallest cover element 2 with a width b = 35 mm:

B = (5-1) x 50mm + 35mm = 200mm + 35mm = 235mm

The maximum possible width B of the cover 2 is determined in particular by the material used, the material thickness and the manufacturing process. The mounting grid (ie the module 7) is in principle freely selectable and is determined by the surrounding housing and its structural design. The cover elements 2 can be arbitrarily arranged due to the modular structure of the system as required by the user or even replaced later. If, in each case, a filling profile 15 is arranged between two cover elements 2 (see Fig. 1), the module 7 is seated together from the width b of the smallest cover element 2 plus the width B _{F of} a filling profile. Thus, for example, results for a smallest cover 2 of the width b = 35 mm and a filling profile with the width B _F = 15 mm, the module 7 with the following width:

Module = b + B _F = 35 mm + 15 mm = 50 mm

For larger cover elements 2, the calculation is analogous, the order of the cover elements 2 is always an integer. From this it can be seen that in the exemplary embodiment the selected module 7 is based on a mounting grid of 50 mm, wherein the filling profile 15 here always has a constant width B _F of, for example, 15 mm.

3a and 3b show schematically the assembly and disassembly process of a modular housing wall 1. The locking rail 10 is the supporting element of the modular housing wall system and takes the cover 2 by means of snapping and the filling profile 15. It can be seen that the covering element 2 designed as a panel serves as a housing wall module which has a planar configuration, can be slid over the lugs 11 arranged on the latching rail 10 due to its U-shaped contour and can be moved by means of its latching means 5, which extend in the longitudinal direction of the cover element 2. are formed inwardly bent edges, in the there located notches 13a latching play (see Fig. 3a). To facilitate the assembly process, the tabs 11 at their free-standing end on an at least partially rounded outline 12a. Similarly, the assembly process of the filling profile 15 (see Fig. 3b). For mounting, the filling profile 15 is preferably pressed without tools between two of the cover elements 2 until it stops against one of the support lugs 18 of the latching rail 10. The filling profile 15 is thereby clamped between the two cover members 2 and locks them against the relevant tab 11 on the locking rail IQ. The locking rail 10 has to fasten the filling profile 15, the support tabs 18, wherein the filling profile 15 after successful assembly then each one Covering element 2 is arranged on the locking rail 10 and brought into positive engagement with the support bracket 18 for attachment, and is preferably additionally fixed non-positively by jamming. The support tabs 18 have to facilitate the assembly process at its free-standing end 19 on the partially rounded outline 12b. Due to this rounded outline then the filling profile 15 can be pushed for mounting with its U-shaped contour particularly easily from above the support bracket 18. In this case, the filling profile 15 is preferably "clipped" onto the support lug 18 without tools, in order then to clamp it by its prestress on the support lug 18 to form a stable connection The upper side of the filling profile 15 then preferably terminates flush with the upper side of the cover elements 2 and thereby yields a nearly flat surface, only interrupted by rounding off at the joints. The lower inwardly directed bends 17 of the side surfaces 16b of the filling profile 15 clamp the filling profile 15 slightly below the locking means 5 of the cover 2 fixed, which in particular provides increased security against unintentional release of the filling profile 15 in vibration and vibration. The bias of the lateral legs 16b of the U-shaped filling profile 15 generated in this way prevents it from leaving its intended end position due to vibrations or shocks. Accordingly, the attachment of the filling profile 15 to the support tab 18 is preferably carried out in addition to the positive fixing, which arises due to its U-shaped cross-section, also also frictionally, in particular in the direction indicated by the arrows 14 direction. Furthermore, the filling profile 15 blocks the respectively adjacent cover element 2 against unlocking. The disassembly of the filling profile 15 is then preferably also without tools. The tabs 11 and the support tabs 18 are each arranged in periodically recurring spacing grid on the locking rail 10. Preferably, a filling profile 15 is arranged between each two cover elements 2. If in the mounted state between two cover elements 2 each have a filling profile 15, then the disassembly of the cover 2 can also be done without tools, if you previously removed the two adjacent filling profiles 15 and then unlocks the cover 2 on the tab 11, for example, with your fingers. For this purpose, the adjacent filling profiles 15 - if they are freely accessible from below - with little pressure without tools between the two adjacent cover 2 in the direction of the arrow 14 is pressed and removed. Otherwise, it is sufficient to use a simple hook-shaped object to help and lift the filling profile 15 from its top side on one side something to then grab it. After disassembly of the two adjacent filling profiles 15 then for disassembly of the cover 2 of this first at one end first on one side then unlocked on the other side on the tab 11 by pressure with a finger from below. In the same way, optionally further locking rails at the other end of the modular housing wall 1 is moved. The cover 2 can then be removed. Is a free accessibility from below not given, then this is a simple hook-shaped object to take help and to detent the cover 2 from above point by point to grab it then.

Fig. 4 shows schematically a preferred embodiment of the modular housing wall 1 with two different variants of a filling profile 15. In this case, the first variant shows a filling profile 15 without further sealing elements in the unassembled and in the assembled state. By the four line-shaped, positive contact surfaces 27, which contact the two adjacent cover 2 at least partially, arises already easy protection against dust and splash water. The filling profile 15 protects the adjacent cover 2 against unlocking and also increases the contact pressure between the cover 2 and the locking rail 10. In addition, the surface of the modular housing wall 1, ie at least the cover 2, the filling profiles 15 and the locking rail 10, preferably electrically conductive properties. The modular housing wall 1 could therefore be used in principle for EMC-tight applications. However, contacting the abutment surfaces 27 with the cover elements 2 generally does not alone suffice as EMC protection, since here the possibly partially resulting free gap lengths are to be regarded as non-EMC-tight. Furthermore, the lateral legs 16b of the U-shaped cross section of the filling profile 15 are concave. Although a simple sealing effect is achieved by the outer edges of the filling profile 15 formed as linear contact surfaces 27, which contact the respectively adjacent covering element 2, the concave side surfaces also serve as free space for receiving additional seals. In the second variant of this embodiment, a seal 20b is therefore provided in each case between the cover elements 2 and the filling profile 15. The seal 20b thereby increases the tightness of the modular housing wall 1 against water pressing in from the outside or penetrating moisture. The seals 20b are preferably self-adhesive and applied on both sides on the filling profile 15 on the lateral limbs 16b outside.

5 shows schematically a further preferred embodiment of a modular housing wall, in particular in an EMC-tight variant. The first variant shows a filling profile 15 without further sealing elements in the unmounted as well as in the assembled state. The surface of the modular housing wall 1, ie at least the cover elements 2, the filling profiles 15 and the locking rail 10, preferably has electrically conductive properties. In addition, the lateral legs 16b of the U-shaped filling profile 15 are slotted transversely in the form of slots 23 for generating shielding spring elements 22 in periodically longitudinally recurring spacing grid. By the resulting shortened linear, positive contact surfaces of the cover 2 against the adjacent filling profiles 15 creates an improved protection against dust or splash water, and an electrical ground contact in the case of electrically conductive surface. The width of the shield spring elements 22 in the longitudinal direction and the gap length of the slots 23 is preferably in each case λ / 10 of the highest frequency to be shielded. In this case, λ corresponds to the wavelength of the electromagnetic waves to be shielded. As a result of the individual shielding spring elements 22 produced by means of the slots 23, which contact the adjacent covering elements 2, an improved EMC Protection achieved. The width of the individual shielding spring elements 22 is then determined by the frequency range to be shielded and the upper damping amount, the width preferably having to be smaller than λ / 10 of the highest frequency. Again, the lateral legs 16b of the U-shaped cross section of the filling profile 15 are concave. In the second variant of an EMC-proof embodiment of the modular housing wall 1, in each case one of the seals 20b is provided in interspaces between the cover elements 2 and the filling profile 15. However, the seals 20b also have an inner core of a soft elastomer, preferably neoprene, which is peripherally surrounded by a conductive fabric structure, preferably a metal textile, and has a rectangular cross-section. Thus, the seal 20b also serves to fulfill additional requirements with regard to the electromagnetic compatibility (EMC) of the modular housing, ie the seal 20b is at the same time also EMC-tight in the frequency range specified for this seal 20b. The seals 20b are preferably formed self-adhesive and applied on both sides on the lateral legs 16b of the filling profile 15 outside.

6a and 6b show schematically possibilities of connecting the modular housing wall 1 to a housing profile 25 in two different variants. FIG. 6a illustrates a simple sealing possibility at an initial or end piece of the modular housing wall 1 against the housing to be sealed. In the embodiment shown, a filling profile 15 seals against the housing profile 25 formed, for example, as an extruded aluminum profile. The simple sealing effect is achieved here achieved the deformation and the contact pressure of the pressed on the support tab 18 Füllprofils 15 against the housing profile 25. The two line-shaped, positive abutment surfaces 27 against the housing already creates a simple protection against penetrating dust or water spray and an electrical ground contact with a conductive surface. As EMC protection, however, this contacting is not sufficient, since the possibly partially resulting free gap lengths are to be regarded as non-EMC-tight. Fig. 6b illustrates an improved sealing ability at the beginning or end of the modular housing wall 1, which comprises latched cover 2 or filling profiles 15, against the sealed housing. This seals z. B. the latched onto the tab 11 cover member 2 against an elastic seal 20c, which is introduced into a Ecknut of the trained example, aluminum extruded profile housing profile 25. Compared with FIG. 6a, this seal 20c increases the tightness against water or moisture penetrating from outside to inside. However, the seal 20c also preferably has an inner core of a soft elastomer, preferably neoprene, circumferentially of a conductive fabric structure, preferably one Metal textile, is wrapped. Thus, the seal 20b is also EMC-tight at the same time for the frequency range specified for this seal 20b, whereby an EMC protection is achieved for the modular housing wall 1 with an electrically conductive surface also in conjunction with the housing profile 25.

Fig. 7a and 7b show schematically the frontal connection of the modular housing wall 1 to the housing profile 25 in two different variants. Fig. 7a shows the frontal end of the cover 2 and the filling profiles 15 against the housing profile 25 without additional sealing elements. Due to the manufacturing tolerances can be produced in this way hardly a simple seal against dust or moisture, at best protection against small foreign bodies, e.g. Screws, washers, wire sections, etc. This use is therefore primarily for the indoor area with a low degree of protection. In contrast, Fig. 7b is an end-face sealing possibility of the cover 2 and the filling profile 15 against the housing profile 25 by here in the example formed as an extruded aluminum housing profile 25 an elastic seal 20c is introduced in a Ecknut. This seals the front edges of the cover 2 and the filling profile 15 against dust and moisture and is therefore suitable for outdoor use. The seal 20c is preferably designed to be electrically conductive, for example, by enveloping an elastic inner core with a metal textile, and thus also represents an EMC protection at the same time.

Fig. 8a and 8b show schematically the cross section of each of a housing with a modular housing wall 1 in two different variants. 8a shows an exemplary housing cross-section in plan view, in which a completely closed housing wall 1 of differently sized cover elements 2 and a plurality of filling profiles 15 is shown. It can be seen that the cover elements 2 can be arranged as desired by the user or can also be exchanged later, since the system is modular. FIG. 8 b shows a further exemplary housing cross-section in plan view with a completely closed modular housing wall 1, which comprises differently sized cover elements 2 as well as a plurality of the filling profiles 15. The cover elements 2 and the filling profiles 15 have different openings 30. The openings 30 serve in each case for receiving and fixing a cable bushing and a cable to be performed in this way through the modular housing wall 1.

Fig. 9 shows schematically a perspective cross-sectional view of a housing with two different variants of a modular housing wall 1. Here is a schematic represented spatial entity, for example a vessel, a housing, a cabinet, a container, a cabin, a room, etc., which at least one floor, a ceiling, side walls and an air-permeable partition wall 29 includes. Preferably, this is a housing for telecommunications equipment, such as a control cabinet. It can thus be seen that the modular housing wall 1 according to the invention can also be used for wall, floor and ceiling surfaces in the same way - closed or provided with openings. Even partitions in horizontal or vertical orientation can thus be realized in a simple manner. The cover elements 2 used in the air-permeable partition 29 comprise a region which is perforated at regular intervals. The cover 2 can be perforated with any hole pattern. It is furthermore conceivable that the cover elements 2 in the air-permeable partition wall 29 are at least partially formed from a wire mesh or mesh.

10a and 10b show schematically the cross-sectional view of another preferred embodiment of a modular housing wall 1. In the illustrated variant, the locking principle is reversed, i. the support tabs 18 have notches 13b, with which the folds 17 for attaching the filling profiles 15 on the locking rail 10 can be brought into engagement. The notches 13b are arranged in each case at the transition between locking rail 10 and support tabs 18. The support tabs 18 have at their free-standing end an at least partially rounded outline 12b. The further located on the locking rail 10 tabs 11, with which the cover 2 for fastening both positive and non-positively engageable and engageable on the locking rail

10 can be arranged, however, have no indentations. The tabs

11, however, also have a partially rounded outline 12a at their freestanding end. To assemble the modular housing wall 1, in this case the filling profiles 15 are first latched onto the support lugs 18 on the latching rail 10. Only then are the cover elements 2 pushed over the tabs 11 on the locking rail, whereby they are supported and held in their final position. An advantage of this embodiment is that the cover elements 2 can be taken out or replaced without having to first remove the adjacent filling profiles 15. The sealing and functional principles described above can be used analogously in this embodiment. Fig. 10b illustrates the embodiment shown in Fig. 10a as a variant with additional seals 20a between the cover 2 and the filling profiles 15, which thus provide a higher degree of protection against dust and moisture and possibly in electrically conductive training an additional EMC protection. The seals 20a are preferably in the concave lateral legs 16a of the Cover element 2 arranged instead - as preferably in the previously described variants - on the filling profile 15th

11a and 11b schematically show the cross-sectional view of another embodiment of a modular housing wall 1. In this embodiment, the use of a filling profile is preferably dispensed with. Again, the cover 2 has a substantially U-shaped cross-section and locking means 5, which are formed as extending in the longitudinal direction, inwardly bent edges. In this case, at right angles to the base 3 of the cover 2 angled bends 2 form the lateral legs 16a of its U-shaped cross-sectional profile. However, the lateral legs 16a of the U-shaped profile at the transition to the base 3 horizontal outwardly facing bulges 4. The bulges 4 in the assembled state produce a linear contact between two adjacent cover elements 2 and thus also form a very simple seal against dust and spray water. Since it is preferably dispensed with a filling profile, the locking rail 10 in this case also no support tabs 18, but only in periodically recurring spaced tabs 11 for attachment of the cover 2, wherein the tabs 11 have notches 13 a, with which the locking means 5 for Mounting one of the cover 2 on the locking rail 10 can be brought into engagement. This use is particularly suitable for indoor use and usually does not provide EMC protection. The advantage of this embodiment is that the cover 2 can be removed or replaced independently. Fig. 11b illustrates another variant of the embodiment described in Fig. 11a with additional seals 20a between two adjacent cover elements 2. The seals 20a are positioned on the side legs 16a below the two protrusions 4 of the cover elements 2 and provide a higher degree of protection against dust and humidity and - in electrically conductive design - possibly an additional EMC protection.
