Description

Use of a junction box

The present invention relates to the use of a junction box for installation in the ground.

As will become clear below in detail, the connection housing can be used specifically on the last section of a data cable network, namely when it is connected to a data cable branching point. The latter can, in particular, be a branch from a strand that runs, for example, along a road in the ground.

The present invention is based on the technical problem of specifying an advantageous use which has a connection housing as its subject.

This is achieved according to the invention with the use according to claim 1. Here i) the connection housing is installed in a base in such a way that the housing interior remains accessible from above via the opening in the connection housing; ii) a data cable is laid in the floor to the connection housing, that is to say in its housing interior; iii) the data cable laid in the housing space is connected to a radio module with an antenna unit; iv) at least the antenna unit is mounted on the connection housing in such a way that it is arranged above the housing interior and is supported by the connection housing as a base.

If the radio module is, for example, a WLAN module, a WLAN network, for example, can be advantageously used with the present subject matter. B. build in public space. By having the junction box built into the ground there is a cavity in the floor structure with the interior of the housing, which opens up various possible uses. This is discussed in the following paragraphs using the example of the development of a district or street with a data connection; further advantages arise below.

The data connection can be, for example, a fiber optic connection, so the data cable can in particular be a fiber optic cable. Regardless of whether it is a connection to a new development area or an existing development, a cable harness is laid in the ground along the road, from which there are branches to the individual connected buildings (the cable harness can in particular be an empty pipe string act, whose conduits are then occupied with the data cables). After laying this cable harness and the branches, the corresponding trench can be filled, i.e. the floor structure can be created. In the case of the road, this can be, for example, several layers of gravel, which is then followed by a surface layer, for example asphalt or slabs or paving stones.

According to the present subject matter, for example, in the course of such a development, additionally to create a public WLAN network, the data cable from the data cable branch point (e.g. branch from the line) is not routed directly to the radio module, but via the connection housing built into the floor. This can open up the possibility of moving it forward, so the later installation of a radio module for public WLAN can be installed in the course of developing the district / street by positioning the connection housing. The effort for this is, since road or earthworks are not carried out without any problems, as described above, than if a subsequent decision to set up the public WLAN network has to be dug up again (tearing open the surface layer, etc.).

With the connection housing built into the floor, there is therefore the possibility of moving forward (in the context of this disclosure also as "pre-assembly") designated. In the course of the development, the data cable itself can also be laid in the connection housing and (temporarily) stored there. On the other hand, this step according to point ii) can also only take place in the course of final assembly, i.e. in the example here when the public WLAN network is actually being built. In general, the connection housing is preferably connected to the data cable branch point via an empty pipe, through which the data cable can then be laid. This data cable routing through the conduit can take place in the course of the pre-assembly (temporary storage of the data cable in the connection housing) or not until the final assembly, i.e. in the course of the erection of the antenna unit according to section iv).

Further preferred embodiments, in particular possible applications and their advantages, emerge from the dependent claims and the entire disclosure, although a distinction is not always made between the different claim categories in the presentation of the features. If, for example, the advantages of an object are described in a specific application, this is to be understood at the same time as a disclosure of a corresponding use. Furthermore, the assembly steps claimed and described in the context of a use should also be disclosed in the form of a corresponding assembly method.

The procedure according to the main claim can be advantageous not only in the case of a move forward, but also, for example, in the case of a public radio network, in particular WLAN, expansion that has already been decided. For a public WLAN network, radio modules that are spatially distributed at many different locations and converge at a higher-level node may be necessary. A distribution box (with splice boxes) or a splice sleeve, for example, can be arranged at the higher-level node. The laying of data cables, in particular fiber optics, is usually carried out from this superordinate node. It can be advantageous to blow in the data cables through empty pipes laid in the ground, for which purpose special tools in the form of a blowing device must be provided at the node. If, according to the main claim, a connection housing is placed in the floor for each point at which a radio module is later to be arranged, the data cables can be laid from the node into the individual connection housing in one operation (each connection housing is via an empty pipe connected to the node). At the junction, the corresponding special tool, for example the blowing device and / or a splicing system for connecting fiber optic cables, only has to be kept available for a comparatively shorter period of time. The actual assembly of the radio modules and positioning of the antenna units, etc. can take time and would delay the laying of the data cables from the node accordingly. The technician at the node would have to wait with his special tool until another technician had connected and installed the radio module. With the procedure according to the invention, on the other hand, after the data cable has been laid in one connection housing, this other technician can immediately go to the next connection housing, so the work is more closely interlinked. The radio modules can then be installed on the individual connection housings one by one.

The multiple use of the connection housing can also be advantageous regardless of such logistical possibilities which the connection housing built into the floor with the housing interior opens up. The connection housing is namely then also used as a base according to item iv), which in the fully assembled state carries the radio module or at least its antenna unit. To put it simply, the connection housing can initially represent storage space or an optional connection (pre-assembly), but at the same time fulfills a supporting function as a base after final assembly. This means that, for example, there is no need to dig up again in order to create a base for the antenna unit and / or the connection of the radio module or antenna unit is also arranged in a comparatively protected manner (in some cases another cable does not have to be laid to the outside, etc.) ). As discussed in detail below, after step iv) the entire radio module can be arranged above the interior of the housing or only its antenna unit. A logic unit of the radio module can therefore also be accommodated in the interior of the housing (which can provide protection, for example). Information given below on the “antenna unit”, for example relating to its positioning, etc., should always be read on the radio module as a whole without expressly specifying the contrary.

As already mentioned, the radio module can preferably be a WLAN module, ie a local radio network module, preferably according to a standard of the IEEE 802.11 family (e.g. IEEE 802.11b, IEEE 802.11g, IEEE -802.11n, IEEE-802.11a, IEEE-802.11ac, IEEE-802.11ax). The bandwidth of the radio module can be, for example, 20 MHz, 22 MHz, 40 MHz, 80 MHz or 160 MHz. The maximum data transmission rate (gross) of the radio module can, for example, be at least 10 Mbit / s, 50 Mbit / s, 100 Mbit / s, 150 Mbit / s, 200 Mbit / s, 250 Mbit / s or 300 Mbit / s, with possible (independent) upper limits at, for example, at most 5000 Mbit / s, 4000 Mbit / s, 3000 Mbit / s, 2500 Mbit / s, 2000 Mbit / s, 1500 Mbit / s or 1000 Mbit / s.

After the step according to item i) and also after the step according to item iv), the connection housing is built into the floor, that is to say lies vertically within the floor structure. Depending on the placement of the connection housing, the latter can be, for example, the road structure or, in the garden / park area, also the soil, e.g. a topsoil / humus layer, or bulk material such as gravel, etc. In the fully installed state there is a The upper edge of the connection housing is preferably essentially flush with an upper edge of the floor structure, e.g. offset vertically by less than 10 cm, 8 cm, 6 cm, 4 cm or 2 cm (within the scope of the usual technical accuracy, an exactly flush installation is preferred, 0 cm). In general, the present subject matter preferably relates to outdoor applications, that is to say the connection housing is placed in an uncovered area in the ground. The antenna unit arranged above the interior of the housing after step iv) is placed above the upper edge of the floor structure, for example at a distance of at least 5 cm, 10 cm, 15 cm, 20 cm, 25 cm or 30 cm (vertically as the smallest distance taken). Possible upper limits can be, independently of these lower limits, for example at most 200 cm, 180 cm, 160 cm, 140 cm or 120 cm. In principle, the antenna unit could also be arranged above the interior of the housing, but not vertically aligned with it (that is, horizontally offset a little, for example on a T-beam). However, after step iv) it is preferably arranged vertically in alignment with the housing interior above this.

As already mentioned, the connection housing is preferably connected to the data cable branch point via an empty pipe. The data cable can then be laid through this conduit later, even if the floor structure has already been restored. The empty pipe can, for example, have an outer diameter of at most 30 mm, 25 mm, 20 mm or 15 mm (a possible lower limit can be at least 7 mm or 10 mm, for example). With a wall thickness of 1-2 mm, an internal cross-section is available in which the data cable is routed well. The empty pipe is preferably made of a plastic material. If the floor structure is produced, the floor material is preferably placed directly on an outer jacket surface of the empty pipe, i.e. it touches it.

The empty pipe can generally, for example, also be laid into the interior of the housing (for example through an opening in a bottom or side wall of the connection housing). It is preferably placed on a side or bottom wall of the connection housing in such a way that it ends there and opens into the interior of the housing. On or in the corresponding wall of the connection housing, for example, a fitting can be arranged, which is attached to the empty pipe. Regardless of the type of attachment, several conduits laid in the floor can also be connected to the connection housing, i.e. at least two and, for example, no more than 10, 8, 6 or 4 conduits. Regardless of the number in detail, for example, an empty pipe can also be installed a cable for the power supply of the radio module can be connected (this can generally also be done via battery or accumulator, for example).

The connection housing can have a total of, for example, a vertical height of at least 40 cm or 50 cm, with possible (independent) upper limits at z. B max. 80 cm or 70 cm. The interior of the connection housing, which is horizontally bounded by the side wall of the connection housing, can, for example, have an internal volume of at least 20 I, 30 I, 40 I or 50 I, with possible upper limits (independent of this) at, for example, a maximum of 100 I, 90 I , 80 I,

70 I or 60 I. Preferably, there can also be a bottom wall that delimits the interior of the housing vertically downwards (but this is not absolutely necessary). In the context of this disclosure, “vertical” and “horizontal” refer to the orientation of the connection housing in the state installed in the ground, ie to the surface of the earth as a reference point (vertical means perpendicular to this, horizontal means parallel to it).

The side wall laterally (horizontally) delimiting the interior of the housing can be composed in relation to the vertical direction; the connection housing can therefore be constructed from a lower part and an attached upper part.

One or more connection points for the empty pipe (s) can then be provided on the former, for example, which can be formed by plug-in fittings, for example. An upper part, for example a street cap, is then placed on such a lower part. On the other hand, the connection housing can also consist of the same material, that is to say monolithically, over its vertical extension. In particular, it can be a continuous injection-molded part. On the side wall of the connection housing specifically the outer wall surface, lies in the course of the installation of the connection housing in the ground z. B the soil material, such as bulk material such as gravel etc.

According to a preferred embodiment, the opening of the connection housing is temporarily closed between the pre-assembly and the final assembly, preferably with a reversibly insertable and removable dis- disgust (in general, a monolithically molded blind closure would also be possible, which is then knocked out, for example). For the final assembly, to which step iv) belongs in any case, the opening of the connection housing is opened, so preferably the reversibly insertable and removable cover is excluded. The "being or remaining accessible" of the housing interior according to item i) naturally means apart from any cover or part otherwise inserted into the opening (but the opening should not be covered with soil material, for example).

In a preferred embodiment, the connection of the empty pipe to the connection housing is also part of the pre-assembly. Depending on the procedure, the laying of the data cable through the empty pipe can on the one hand also be part of the forward laying. The data cable can therefore be laid through the empty pipe into the interior of the housing and stored there (for the time being); the opening of the connection housing is or will then be temporarily closed and opened for final assembly. On the other hand, the data cable can also only be laid in the course of the final assembly. The connection housing can therefore be opened, in particular the cover can be removed from the opening and then the data cable can be laid through the empty pipe into the connection housing.

According to a preferred embodiment, steps ii) and iii) take place in the course of the pre-assembly, in which case the data cable is laid into the interior of the housing and the radio module is already connected. The radio module is then not fully assembled, so the radio module as a whole, or at least the antenna unit thereof, is not placed above the interior of the housing. Instead, the radio module is housed in the interior of the housing and this is closed with the cover. If the radio network, for example the public WLAN network, is then to be set up later, the connection housing can be opened, that is to say the cover can be removed and the radio module or antenna unit can be removed. This can, for example, open up an approach based on the division of labor in that a specialized technician can work the radio module or modules at the different points, i.e. at can connect to the various junction boxes. Then another technician can take over the final assembly without any further special work on the data cable network or the connection to it being necessary.

In an alternatively preferred embodiment, the connection of the radio module is part of the final assembly, so the connection housing is opened and then the radio module is connected. Such a procedure can be of interest, for example, in the case of a forward shift as described at the beginning. As described above, the laying of the data cables can already have taken place in the course of the pre-assembly or can only be done during the final assembly.

The antenna unit or the radio module is preferably mounted on the connection housing via a carrier element. In general, this could also be, for example, a strut that extends into the housing interior and is supported on the housing bottom. The carrier element is preferably arranged in the opening of the connection housing, namely it sits on a support formed on the opening. The support could generally also be formed by a pin inserted into the housing wall; it is preferably a step formed by the connection housing itself. An inner wall surface of the connection housing, which horizontally delimits the housing interior, is thus horizontally offset outwards at the upper end, so that there is a step there. The mounting of the carrier element over the support or the step can result in a stable structure, that is to say hold the antenna unit or the radio module reliably in position.

In a preferred embodiment, the support, in particular the step, carries the cover between pre-assembly and final assembly. This in turn results in an advantageous multiple use, the support holds the cover before final assembly z. B. enters position, then it allows the stable assembly of the support element. The cover is preferably seated on the support, in particular the step, in such a way that its upper edge is flush with an upper edge of the side wall of the connection housing. In general, the cover that closes the connection housing between the pre-assembly and final assembly can also be used as a carrier element. It can, for example, have a strut that extends vertically downwards on its underside (based on the orientation before final assembly) and can be placed upside down in the course of final assembly so that the strut extends upwards. This strut can then carry the antenna unit or the radio module. On the other hand, the cover and the carrier element can also be under different parts, which z. B. can enable optimization for the respective application. In the course of final assembly, the cover is preferably exchanged against the carrier element.

In a preferred embodiment, a housing attachment is then placed in step iv), in which the antenna unit or the radio module is then arranged. The housing attachment is a flea body, for example in the form of a tube, preferably a tube closed at one of its two ends. A flea post closed at one end can therefore be provided, for example. Such a housing attachment can then simply be slipped over, that is to say pushed onto the antenna unit or the radio module from above (the closed end of the housing attachment is at the top).

The connection housing then preferably also carries this housing attachment as a base, ie the latter is or is at least indirectly fastened to the connection housing. The carrier element, which holds the antenna unit or the radio module above the housing interior, then preferably carries the housing attachment at the same time. The carrier element can, for example, form a circumferential contact surface for the housing attachment on which the latter rests. The contact surface can, for example, point radially outward, so that the housing attachment is in contact with an inner wall surface facing radially inward. The contact surface can, however, also be oriented vertically so that the housing attachment is seated with a contact surface directed vertically downwards. The relative fixation of the housing attachment and the carrier element can, for example, take place with screws, but alternatively or additionally, for example, a tensioning strap can also be applied. This can generally create a positive fit with respect to the vertical. The housing attachment can, for example, be provided at its lower end with a flange, via which the housing attachment is mounted on the connection housing, preferably via the carrier element. This flange is preferably combined with a flange of the carrier element, which results in a flat and therefore stable contact. Particularly preferably, the two flanges can then be connected in a vertically form-fitting manner with a tension band. For this purpose, the tensioning band can encompass the two flanges vertically at the top and bottom, that is to say, for example, made of metal with flanged edges.

Regardless of the type of relative fastening of the housing attachment and connection housing or carrier element in detail, this fastening is preferably locked in a tamper-proof manner. This can be done, for example, with a lock that blocks the tensioning lever of the tensioning strap. In the case of a screw connection, the shaft of the screw head can be opposite to the screw head, for example with a hole through which, for example, a wire lock or a (small) padlock is set. In the variant with the flanges placed next to one another, these can also be connected to one another directly via a lock, for example. B. a padlock. When screwing, for example. Also screws with non-standard screw head profile can be provided, which accordingly can only be operated with a special tool. The protection against manipulation is preferably achieved via active locking, for example a lock.

According to a preferred embodiment, the antenna unit or the radio module is arranged in a sealing container. A cup-shaped sealing container is preferred, ie it has a side wall and a bottom wall and an open side opposite the bottom wall. The bottom and side walls are preferably in one piece (cannot be separated without being destroyed), particularly preferably monolithic thisch (consistently made of the same material), e.g. as a thermoformed or injection molded part.

The antenna unit or the radio module is arranged in the sealing container, preferably following step iv) (generally also in the course of a pre-assembly). In particular, the pot-shaped sealing container can simply be slipped over the antenna unit or the radio module, which creates a certain level of protection (e.g. also in the case of a housing attachment when rainwater drips into it). The sealing container can, for example, have an internal volume of at least 0.5 l, 1.0 l or 1.5 l, with possible (independent) upper limits of, for example, a maximum of 5 l, 4 l or 3 l For example, have an internal volume of at least 6 I, 7 I or 8 I, with possible (independent) upper limits at z. B. at most 30 I, 20 I or 15 I (this should also be disclosed regardless of whether a sealed container is provided or not).

According to a preferred embodiment, the connection housing is at least partially concreted in during installation in the ground. In other words, concrete thus forms at least part of the floor structure; it can, for example, enclose an upper section of the connection housing. In principle, the connection housing can also be set in concrete over its entire vertical fleas, but a section of it can preferably also remain free of concrete. If, for example, the upper section remains free of concrete, a layer corresponding to the rest of the floor structure can enclose the connection housing there, for example a covering layer (road), gravel / gravel or topsoil / flumus layer.

As already mentioned, the data cable laid in step ii) then extends in a preferred embodiment from a data cable junction point to the connection housing, the data cable junction point being on an empty pipe run. The conduit is laid in the ground, for example along a road. There are preferably a large number of data cable branch points along the empty conduit, for example at least 5, 10, 15 or 20 (possible upper limits can be a maximum of 1000, 500, 200 or 150). Preferably, not only several connection housings with radio modules, but also buildings, i.e. residential and / or commercial or office buildings, are then connected via the conduit section, i.e. the higher-level node (distribution box / splice sleeve). Connection housings with radio modules are then connected via part of the data cable branch points, and a building is connected via another part.

The invention also relates to a radio unit which results as the subject of a use described here, that is to say has a connection housing built into the floor, which carries at least the antenna unit of a radio module as a base.

In the following, the invention is explained in more detail with the aid of exemplary embodiments, wherein the individual features within the framework of the independent claims can also be essential to the invention in other combinations.

Preferred embodiment of the invention

FIG. 1 shows a structure 1 with a connection housing 2, which is composed of a lower part 3 and an upper part 13. The upper part 13 is a street cap, the lower part 3 is discussed in detail with reference to FIGS. 7-13. The connection housing 2 delimits a housing interior 4, which is subdivided into a lower section 4.1 and an upper section 4.2 according to the division into lower and upper part 3, 13. On the upper side, the connection housing 2 has an opening 5, via which the housing interior 4 is accessible, and which in the present case is closed with a cover 6.

The connection housing 2 is equipped with connection points 7.1, 7.2. An empty pipe 8.1 is attached to the connection point 7.1, which extends from an empty pipe run to the connection housing 2. At the connection point 7.2, depending on the application and procedure in detail, an empty connection pipe 8.2 is attached, which then connects the connection housing 2 with the distributor / user, for example a building.

In this example, the connection housing 2 is placed in the layer structure 10 of the street 15 (see also Figure 2) so that an upper edge 2.1 of the connection housing 2 is flush with an upper edge 9 of the layer structure 10, which is sketched in the left half of the figure. An upper layer 10.1 can be, for example, the paving layer (sidewalk) or asphalt surface layer (road), the layer 10.2 underneath can accordingly be a bed or a binder layer. The underlying layers 10.3, 10.4 represent support layers. If the connection housing 2 is positioned, the position of the upper edge 9 is already known (determined), even if the layer structure 10 is sometimes not created until much later. FIG. 2 illustrates in a plan view how the connection housing 2 is placed on an empty pipe section 23, from which an empty pipe 8 is branched off at a data cable junction point 24 and laid to the connection housing 2. In the present example, the conduit 23 runs along a road 15, specifically below the sidewalk 22 arranged next to the roadway 27. The reference symbol 26 marks a boundary between the road 15 and an adjacent property 25, which is, for example, a Private property or public space, such as a park, etc. can act. In the example shown, the connection housing 2 is placed in the area of the walkway 22. Alternatively, however, it can also be arranged on the property 25, for example, see also FIG. 5 and the comments on the installation in the floor.

The empty conduit 23 extends from a junction 29, there can be arranged, for example, a distribution box or a splice sleeve (an entire local area or entire street can be connected via this). From the empty pipe strand 23 at other data cable junction points, an empty pipe in each case also goes off, in the manner according to the invention to a connection housing arranged there or, for example, also directly to a respective building (residential building or office building).

As shown schematically in FIG. 2, a radio module 30 is connected via the connection housing 2, that is to say via the data cable branch point 24 to the node 29. In the present case, it is a WLAN module and a public WLAN network is made available .

FIG. 3 illustrates the corresponding structure in detail; the connection housing 2 built into the base 35 with the attached empty pipes 8.1, 8.2 can be seen. One of the empty tubes 8.1, 8.2 connects the connection housing 2 to the data cable branch point 24, the other to a power supply. In the same way as in FIG. 1, the floor 35 can be the layer structure 10 of a road, but likewise, for example, gravel and gravel or earth can also form the layers 35.1, 35.2, 35.3. As can be seen from FIG. 3, which schematically partially shows a section, the radio module 30 with its antenna unit 30. 1 is arranged above the housing interior 4 of the connection housing 2. Starting from the assembly situation according to FIG. 1, that is to say the connection housing 2 built into the base 35, the opening 5 of which is closed by the cover 6, the cover 6 is first removed to position the situation according to FIG. Then from the node 29 via the data cable branch point 24 a data cable 31 is blown through the empty pipe 8.1, while a power supply cable 32 is passed through the empty pipe 8.2 into the connection housing. The data cable 31 is connected to the radio module 30; the same applies to the power supply cable 32.

The connection housing 2 is then used as a base 33, namely it carries the radio module 30. A carrier element 34 is provided for this purpose, which is inserted into the opening 5 instead of the cover 6. The completely installed arrangement then forms a radio unit 300.

In the schematic illustration according to FIG. 3, a housing attachment 36 can also be seen, in the interior 37 of which the radio module 30 is then arranged. The housing attachment 36 is attached to the carrier element 34, see Figure 5 in detail. Furthermore, an optionally provided sealing container 38 can be seen, which is additionally placed on the radio module 30 and protects it. FIG. 4 shows the sen pot-shaped sealing container 38 in a detailed view obliquely from below, the radio module 30 is placed in the interior 39 (the sealing container 38 is placed).

FIG. 5 shows in a detailed view how the carrier element 34 sits in the opening 5 of the connection housing 2, specifically how it sits on a step 50. The cover 6 is previously seated on this step 50. Furthermore, the figure illustrates the attachment of the housing attachment 36 to the carrier element 34, which in the present case takes place by screwing, with a contact surface 51 creating stability. In the illustration according to FIG. 5, the connection housing 2 is partially concreted in, so concrete 55 forms part of the Bottom 35. This creates stability, especially with regard to a tilting moment of the housing attachment 36.

FIG. 6 shows a structure that is comparable with regard to the connection housing 2, in which, however, the carrier element 34 and the housing attachment 36 are designed differently in detail. The connection housing 2 is divided analogously to FIG. 1 into an upper part and a lower part, the upper part being a height-adjustable street cap 60. An assembly situation analogous to FIG. 3 is shown, the cover 6 has thus been removed and replaced by the carrier element 34. This has a support strut 34 on which the radio module 30 is or is mounted. Furthermore, the Trä gerelement 34 has a flange 61, via which the housing attachment 36 is fastened with a tightening strap 62.

FIG. 7 illustrates this fastening in a detailed view; the housing attachment 36 also has a flange 70. This is arranged at the lower end of the housing attachment 36 and sits on the flange 61 of the carrier element 34. A sealing element 62 is arranged in between. The tension band 62 engages around the two flanges 61, 70 and holds them together vertically. In FIG. 7, a lower flange 75 of the carrier element 34 can also be seen, with which the latter is seated on the step 50. Holes 76 are provided in the flange 75, and the support element 34 is fastened to the connection housing 2, that is to say to the street cap 60, by means of screws (not shown here).
