Description

The present invention relates to a connection housing device for installation in the floor and providing a data cable connection.

As will become clear in detail below, the present subject is specifically directed to the last section of a data cable network, namely the connection of the user / distributor or building to a data cable junction. This can be, in particular, a branch from a strand that runs, for example, along a road in the ground. In such a situation, the connection housing device discussed here can be placed between the branch and the building, which can simplify its development, that is to say connection to the data cable network. This is part of the subject matter of the invention, but is briefly outlined below, because the function of the connection housing device can be better understood against the background of this application.

In the application, which, as stated, is the subject of the invention, the connection housing device is placed in the floor, for example in the area of a street, in such a way that the interior of the housing is still accessible from above after the floor or street structure has been produced. Before the construction of the ground / road structure, i.e. before the excavation of a trench dug in the course of the data network development, an empty pipe is laid between the data cable branching point and the connection housing. In simple words, the data cable or the empty pipe is therefore not routed directly from the branch to a respective user / distributor, but via the connection housing. Depending on the application, different advantages can result, in the following the development of a residential building in the existing building is discussed as an example.

If the data connection in the inventory is retrofitted, the network can typically be laid for entire streets or parts of towns or cities. The road, for example the sidewalk, is then dug up and z. B. laid a cable harness from which a cable is branched off for each household to be connected (at a respective data cable branching point). The roadside ditch is then filled again and the previously broken cover layer is restored.

The inventors found that, however, usually only the smaller part of the residents or owners immediately decided to retrofit (typically 1/3). Further connections will only be requested later, gradually. For this purpose, it is then necessary to dig up again, in particular to break up the cover layer and to branch off to the respective building, which means considerable effort. The floor structure must then also be restored with each subsequent covering (in particular the top layer / the covering).

In contrast, the procedure according to the invention offers the possibility of placing a connection housing in each of the buildings that have not yet been connected. The data cable can then either already be laid into the connection housing and stored there (for the time being), or the connection housing can at least be connected via the empty pipe. If the building is to be connected later (after the road has actually been opened), depending on the position of the connection housing, at least the sidewalk / street does not have to be dug up, sometimes no digging is necessary (if the connection housing is located directly on the building, see below in detail).

Even if the data cable is not routed straight into the connection housing, but is initially only connected to the data cable junction via the empty pipe, subsequent connection of the building can be significantly simplified. The data cable can then be subsequently inserted or blown through the empty pipe, which is preferably carried out by the data cable branching point or via it.

An object of the present invention is to provide an advantageous connection housing device for such or the applications described below.

This is achieved according to the invention with the connection housing device according to claim 1. As described above, their connection housing delimits a housing interior which is accessible from above via an opening. A lower part of the connection housing has a side wall which horizontally delimits at least a lower section of the housing interior. Furthermore, the connection housing device has a connection point for attaching the empty pipe, which is laid in the ground between the data cable branching point and the connection housing. This connection point is arranged above a lower end of the housing interior. The lower part preferably also has a bottom wall which delimits the interior of the housing vertically downwards.

Put simply, according to the invention, the empty pipe does not open into the interior of the housing from below (not at its lowest point), but somewhat further up. In other words, the interior of the housing goes down a little drawn, which can be advantageous, for example, due to the enlarged interior. This can be divided into vertical areas, for example. B. also open up multiple users / distributors. Another advantage of the connection housing that is pulled down can be that it can then be placed directly on a support plate, for example, so that no additional installation device is required (the positioning of the support plate can be predetermined, for example, for reasons of frost protection, for example be).

The connection housing which is pulled downwards can also be advantageous, for example, in that its standing surface can be placed vertically approximately at the level of the laying depth of the empty pipes. This means that in the area of the connection housing, for example, it does not have to be excavated much further or relined, but the connection housing can be placed together with the empty pipes without further earthwork.

Preferred embodiments are the subject of the dependent claims as well as the entire disclosure, wherein the representation of the features does not always differentiate in detail between device and method or use aspects; in any case, the disclosure is to be read implicitly with regard to all claim categories. If, for example, the advantages of the connection housing device are described in a specific application, this should also be understood as a disclosure of such an assembly method or a corresponding use.

In a preferred embodiment, the connection point on the connection housing is oriented obliquely in such a way that a center axis of the attached empty pipe lies at an angle to the vertical direction in the area of the connection point. The angle included with the vertical direction can be, for example, at least 10 °, further and particularly preferably at least 20 ° or 30 °. Possible upper limits can be, for example, at most 80 ° or 70 °. The smaller of two angles, which the central axis of the empty tube encloses with the vertical direction, is considered in each case.

The oblique, in particular obliquely upward, empty pipe opening into the connection housing can be advantageous, for example, in that the data cable is less easily caught in the connection housing when it is blown in. With a center axis oriented obliquely upwards, it is accordingly steered upwards a little, i.e. in the direction of the opening above. An empty pipe that opens diagonally upwards can, for example, also be advantageous in that the connection point can then be somewhat above the laying depth of the empty pipe and this can already be curved upwards in the ground or floor structure while maintaining a minimum radius. The connection point can thus also be placed at a height, for example, so that it can still be easily accessed from above through the opening of the connection housing.

In general, "vertical" and "horizontal" refer to the orientation of the connection housing device during assembly or in the assembled state. The vertical direction can in particular be perpendicular to a plane in which there is a footprint of the connection housing device, in particular of the lower part (see below). "Top" and "bottom" refer to the vertical direction, and "sideways" refer to the horizontal direction; “Inside” means towards the inside of the housing, “outside” away from it.

According to a preferred embodiment, the bottom and side walls of the lower part are monolithically formed with one another, that is to say they are formed from the same, uninterrupted, continuous material. In general, the lower part could also be formed from metal, wherein the monolithic configuration could be achieved, for example, by deep drawing or metal die casting. A plastic material is preferred; the monolithic lower part can be produced, for example, by injection molding. The plastic lower part is particularly preferably produced by thermoforming, ie it is a thermoformed part. During production, the material is made deformable, for example, by heating and then drawn into the mold by means of excess and / or negative pressure. With this type of production, on the one hand, a molded part with a comparatively large interior space can be created (which is desired in the present case), whereby a stable structure can nevertheless be achieved with a corresponding contouring (in particular with indentation and bulge areas).

In a preferred embodiment, the side wall of the lower part is offset horizontally inwards in an indentation area. This can be advantageous in terms of stability, for example. In the indentation area, the side wall can, for example, be offset inwards by at least 5 mm, 10 mm, 15 mm, 20 mm, 30 mm, 40 mm or 50 mm, with possible (independent of this) upper limits at z. B. at most 150 mm or 120 mm.

In general, the lower part could also limit the entire interior of the housing, that is, the lower part could represent the connection housing. An upper part, in particular a street cap, is or is preferably placed on the lower part, see below in detail. In general, the connection point could also be arranged on the upper part be, it is preferably arranged on the lower part. It is preferably arranged in the indentation area. This positioning can be advantageous, for example, because of the greater stability in the indentation area because of the contouring.

The indentation area preferably extends vertically only over a section of the lower part, that is to say the side wall again runs outwards at the upper end of the indentation area. The connection point is preferably arranged there and thus at the same time positioned in the desired inclined position because the side wall runs obliquely outwards there.

According to a preferred embodiment, the side wall is offset horizontally outwards in a bulge area; with regard to possible quantification, reference is made to the information in the penultimate paragraph. The bottom wall of the lower part preferably forms a standing surface in the bulge area, with which the lower part can be set up or on which it can be placed. Specifically, the outer surface of the bottom wall facing away from the interior of the housing forms the standing surface. With this footprint, the lower part could generally also be placed directly in the floor, for example placed on a ballast bed. The lower part with the base is preferably placed on a support plate (which should also be expressly disclosed with regard to a corresponding use).

For example, a concrete plate can be provided as the support plate, but a plastic support plate is preferred. In particular, it can be an injection molded support plate, that is an injection molded part. Irrespective of this in detail, an advantage of the lower part with a standing surface can be, for example, that it can be put on directly, that is to say no separate installation device is required. Smaller assembly aids, such as washers arranged between the bottom wall and the support plate, are not considered to be set-up devices (they can, for example, allow water to drain from the interior of the housing).

Overall, the connection housing preferably has a (vertical) height of at least 40 cm or 50 cm, with possible (depending on this upper limits at, for example, at most 80 cm or 70 cm. The lower part itself preferably has a height of at least 15 cm or 20 cm and (depending on it) e.g. at most 35 cm or 30 cm.

In a preferred embodiment, the bottom wall of the lower part is provided with a hole in the bulge area. This can be used on the one hand for mounting on the support plate, on the other hand it can additionally or alternatively also serve to drain water that has penetrated into the interior of the housing. Water can penetrate, for example, if a cover closing the top opening is not placed correctly due to an assembly error.

In a preferred embodiment, the bottom wall of the lower part is offset vertically upwards in a central region, ie it is higher there than in the bulge region. This can be advantageous in terms of stability, for example, and / or a more stable position of the lower part can also be achieved with stand areas arranged only in the bulge area (s). In connection with the bottom wall provided with a hole in the bulge area, the elevation in the middle area can support the drainage of the water, for example. The “middle area” can, for example, lie radially within the indentation areas with respect to a vertical axis.

In a preferred embodiment, a plurality of indentation and bulge areas follow one another alternately. In general, a stable position could also be achieved, for example, over two bulge areas, each of which extends over a somewhat larger angular area. There are preferably at least three bulge areas (each of which forms a standing area), possible upper limits can be, for example, at most eight or six bulge areas, four bulge areas are particularly preferred, compare the exemplary embodiment. Furthermore, there is then a number of indentation areas corresponding to the number of bulge areas (at least two or three, no more than eight or six, particularly preferably four).

As already mentioned, in a preferred embodiment, an upper part is placed on the lower part, particularly preferably a street cap. This can be provided, for example, from metal, e.g. B. die casting, or from a plastic material (hard plastic), for. B. polyamide, especially glass fiber reinforced, or from a copolymer material. The connection housing device is then integrated into the floor or road structure such that an upper edge of the road cap lies essentially flush with the upper edge of the layer structure, that is to say with the upper edge of the cover layer in the case of road construction. “Essentially flush” means, for example, an offset of less than 3 cm, 2 cm or 1 cm. Flush installation is preferred (0 centimeters) within the scope of the usual technical accuracy.

On the upper side, the upper part or the street cap has a cover which can be reversibly removed and reinserted. The lid can preferably extend a bit into the opening, which can ensure a secure fit. In particular, it can have a closable lid be provided to prevent unauthorized access to the interior of the housing. The lid can then only be opened with a special key.

According to a preferred embodiment, the lower part is provided at an upper end with a horizontally projecting flange on which the road cap rests. The road cap could, for example, be fastened by means of a clip, preferably it is screwed to the flange. The flange can therefore preferably be provided with one or more holes for introducing screws (these are screwed into the attached connection housing from below).

According to a preferred embodiment, a fitting forms the connection point, ie the buried hollow pipe is or is attached to the fitting. The fitting preferably forms a sealed connection point, that is, it is sealed against the attached empty pipe. For this purpose, it can have a sealing element to which the empty pipe is attached, preferably the empty pipe is inserted. After inserting the empty tube, a lock and thus pull-out protection can be created (screw fitting), for example with a union nut that is screwed on or screwed on. The fitting preferably has a locking ring with ratchet teeth, which engage with the hollow tube and create a pull-out protection. In this case, it is particularly preferred that no additional screwing is necessary (plug fitting).

Regardless of the design in detail, the fitting is preferably inserted into a hole in the side wall of the lower part. As explained above, this hole is preferably arranged in an indentation area, particularly preferably at its upper end, where the side wall runs obliquely outwards.

The hole is preferably contoured in such a way that the fitting rests in a rotationally secure manner (based on a rotation about the central axis of the empty pipe). When viewed in a section perpendicular to the center axis of the empty pipe, the hole has a non-circular shape which takes into account the outer shape of the fitting considered in the same section, preferably being complementary to it. The twist-proof seat of the fitting can, for example, simplify the assembly of the data cable, namely the sealing of the fitting against the data cable passed through. This can preferably be done by tightening a union nut, the connection housing already sitting in the ground and the fitter having to mount the fitting from above through the opening. The twist-proof fitting can then be operated, for example, with only one hand and sealed against the data cable, which can make handling easier.

In general, regardless of the torsion-proof seat, the fitting preferably has a sealing element with which the data cable passed can be sealed against the fitting or the empty pipe inserted into the fitting on the ground side. This sealing element is preferably axially compressed in relation to the center axis of the empty tube, in order to consequently create a radial seal. The axial compression is preferably achieved with a union nut, which is guided on the outside on the housing of the fitting, the force transfer to the sealing element being achieved via an inwardly adjusted collar.

In a preferred embodiment, a guide device is arranged on the union nut, which guides the inserted, in particular blown-in, data cable in the direction of the opening of the connection housing and can thus help prevent tangling, see below in detail. The guide device is preferably a piece of pipe. This is preferably attached to the fitting via an adapter, which is particularly preferably seated on the union nut of the fitting. The adapter preferably has an inner contour that is complementary to the outer contour of the union nut, so that the union nut can be rotated by rotating the adapter. The pipe section which is preferably provided as a guide device is preferably inserted at the axially opposite end of the adapter and held in a form-fitting manner. The pipe section is preferably inserted up to a stop formed in the adapter; this stop is preferably chamfered on the side axially opposite the pipe section. The data cable can then slide easily into the pipe section along this chamfer.

According to a preferred embodiment, the housing interior is subdivided into a lower area and an upper area. In principle, it is also possible to subdivide into more than two vertically consecutive areas, preferably exactly two areas. For example, a removable shelf or a flap that can be opened and closed can be provided between the upper and the lower region. In any case, a certain spatial separation has been created.

This can be advantageous, for example, in that the connection housing can also be used to connect several users or distributors. For example, two neighboring residential buildings can be connected, even if one connection should be made immediately and the other should only be moved forward. The lower area of the housing interior can then be used, for example, in order to implement the immediate connection, that is to say, for example, to implement a plug connection as described below, in particular to accommodate a plug housing. Then the later Relocated the connection of the other building, can be handled in the upper area of the interior of the housing without the risk of impairing the other connection. Alternatively, the lower housing interior can also be used, for example, to (temporarily) store a coiled data cable, for example, a corresponding cassette can be placed there.

The invention also relates to a connection device which is composed of a connection housing device disclosed here and a hollow tube which is placed at the connection point of the connection housing device. In general, the connection housing device can preferably have at least two, more preferably at least three, connection points, with possible upper limits for e.g. B. at most ten, eight or six connection points. Exactly four connection points are particularly preferred, that is to say four hollow tubes are then attached to the preferred connection device.

The invention also relates to a floor element, in particular a road element, in which a connection housing device or connection device is installed in the manner disclosed here.

• - mit der Öffnung nach oben weisend;
• - horizontal im Bereich einer Straße;
• - auf einer vertikalen Höhe, die innerhalb einer fertigen Aufbauhöhe eines Schichtaufbaus der Straße liegt, wobei aber die Öffnung und damit der Gehäuseinnenraum von oben zugänglich bleibt;

bei welchem Verfahren ferner ein Datenkabel oder ein Leerrohr für ein Datenkabel zwischen der Datenkabels-Verzweigungsstelle und dem Anschlussgehäuse verlegt wird, das also die Datenkabels-Verzweigungsstelle mit dem Anschlussgehäuses verbindet.Furthermore, the invention also relates to a method for providing a data cable connection for a data user or distribution point, specifically a connection to a data cable branch point, for which purpose the connection housing of the connection housing device is positioned between the data user or distribution point, specifically

• - with the opening facing upwards;
• - horizontally in the area of a street;
• - At a vertical height, which is within a finished construction height of a layer construction of the street, but the opening and thus the interior of the housing remains accessible from above;

in which method, furthermore, a data cable or an empty pipe for a data cable is laid between the data cable branch point and the connection housing, which thus connects the data cable branch point to the connection housing.

In particular, the invention also relates to the use of a connection housing device disclosed in the present invention.

Further application or process / use details are described below. Reference is made here to a “connection housing”, which in any case has the lower part, preferably has the lower and upper part, in particular a street cap as the upper part.

However, the procedure according to the invention is advantageous not only in the development of existing buildings discussed at the beginning, but also in the new building. In a new development area, it may at first glance appear less complex and less expensive to connect the individual buildings or building base areas directly, i.e. to lay the data cable or empty pipe for this purpose directly from the data cable junction point to the building or its base area. However, the inventors have found that the construction progress on the individual plots can diverge considerably in practice, so that some buildings are already occupied, for example, while others are still in the shell construction stage, if at all. The network operator can therefore not access the entire area in one go, but only gradually.

The procedure according to the invention also opens up the possibility of moving it forward, for example to the respective property. Where the street, in particular the sidewalk, runs later, the connection housings can be placed, for example, on the property boundaries. Regardless of their position in detail, the network operator can then lay the individual data cables (for the individual buildings or building floor areas) in one go up to the connection housing, i.e. in one work cycle (within one working day or several connected ones). This advance to the connection housing can take place, for example, as soon as the first household receives its data connection. If the other households then gradually need their data connection, the effort involved in laying these last meters is significantly less than laying from or via the data cable junction. The latter usually requires at least two technicians; the last few meters can also be installed by a single technician.

In general, the data cables are preferably laid from a node at which several, that is to say the individual data cable junction points converge. As described above, a cable or conduit can extend from this junction along the street (in the ground), with one cable / conduit going off each of the buildings (or users / general dividers in general). A distribution box (splice box) or a splice sleeve, for example, can be arranged at the higher-level node. There can be a certain distance between the node and the individual buildings (users / divider), and the data cables are usually blown into the conduits with a special tool and thus advanced over correspondingly large distances. In this regard, the procedure described above, i.e. the pre-routing of data cables that are initially not required in one work step, can be advantageous in that the corresponding special tool (blowing device) then only has to be provided once at the node. The work at the node may also require special tools with regard to the cable connection / branching there, for example a cable splicer in the case of the preferred glass fiber cables. This also then only has to be provided once, together with appropriately trained personnel, at least at the node (sometimes also in general, see in particular the "Plug" variant below).

In the case of the building, the connection housing arranged on the street is located outside the building's base area, i.e. outside the area occupied by the building including the walls, i.e. the gross base area taken according to the external dimensions. This can be smaller than the built-up area (roof overhang). Although the connection housing is placed outside the base area, it can certainly lie within the built-up area, for example in the case of a connection housing placed directly on the outer wall of the building. The latter is particularly important when retrofitting existing buildings. On the other hand, however, a certain minimum distance from the building floor area can also be preferred.

Due to the placement of the connection housing on the street (in other words: bordering the roadside), in particular the sidewalk, e.g. bordering the property boundary, the sidewalk / street does not have to be dug up again when it is subsequently occupied, e.g. it can be opened or dug laterally from the property to the connection housing. In general, the "horizontal" positioning of the connection housing "in the area of a street" means that the connection housing is vertically aligned with the layer structure of the street. When the road is finished, the connection housing is located in the layer structure of the road (because it is also placed at a vertical height within the finished layer structure height).

The "layer structure" includes in particular a base layer, although several base layers placed on top of each other are also possible. The building material mixture of the base layer can in particular comprise ballast, which is compacted. This is followed by a covering layer, for example asphalt or slabs or paving stones, but in general an unbound covering layer is also possible (a layer of gravel in the case of a gravel path). Placement in the layer structure of the road is advantageous, for example, insofar as this layer (s) is or are compacted, that is to say they offer good mechanical stability. This is of particular importance in the present context because the data cables or the comparatively thin conduits are relatively sensitive to them. The pipes (made of plastic) or data cables can easily bend, whereby the glass fibers can break and lose their function. If you did not place the connection housing in the defined layer structure of the road, but at any place in the ground, it could lead to kinking or other damage to the empty pipe / data cable when settling in the ground. The layer structure of the road, on the other hand, is compacted in a defined manner. B. with a dynamic plate printing device and / or a ram probe (uniformity of compression) can be checked (or checked in road construction).

When assembling or manufacturing the layer structure of the road is then laterally around the connection housing z. B. compacted a gravel layer, for example with a vibrating plate. There are preferably a plurality of gravel layers placed one on top of the other, that is to say one after the other, which are each compressed around the connection housing. The connection housing is then defined and stably installed, especially after the cover layer has been applied.

Due to the necessary coordination with the civil engineering / road construction companies etc., the positioning in the road area may initially appear to be disadvantageous, but the overall advantages outweigh the technical advantages. The term "road" includes both the roadway and the sidewalk, other components can be a bike path and also median or hard shoulder (overland / highway). In principle, the connection housing can be placed in any of the above-mentioned areas (in the area of the roadway or bike path or the median / side lane or the walkway); positioning in the area of the walkway is preferred, particularly in the case of customary development in local / urban areas on the property boundary (on the roadside).

The connection housing can also be placed directly adjacent to the building floor area, for example if the outer wall in the urban area is located directly on the walkway. On the other hand, there may also be a minimum distance of at least 1 m, 2 m or 3 m between the building floor area and the connection housing. Possible upper limits, which also depend on the size of the property, can be, for example, at a maximum of 50 m, 40 m, 30th m, 20 m, 15 m and 10 m.

As already mentioned, the connection housing is placed at a height within the finished layer construction height of the street. This does not mean that in order to fulfill the main claim, the layer structure must also be created (which in practice is usually carried out by other workers and sometimes much later). Once the layer structure has been created, however, the connection housing sits within it. An upper edge of the connection housing is preferably essentially flush with the upper edge of the layer structure (the position of which is known in advance), that is to say with the upper edge of the cover layer.

In view of the preferred fiber optic cables, which have certain minimum bending radii (risk of breakage), an opening with certain minimum dimensions may be preferred. An average opening width, which is the average of the largest and smallest horizontal extension of the opening and, in the preferred case, corresponds to the circular shape to the circular diameter, can be, for example, at least 5 cm, further and particularly preferably at least 10 cm or 12 cm. Possible upper limits (regardless of this) can be, for example, a maximum of 40 cm or 30 cm. The lid is then sized according to the opening.

As explained above, there can be numerous advantages if the “data user or distribution point” is a building, for example an office or residential building, both an apartment building and in particular a single-family house being considered. As mentioned at the beginning, however, the “data user or distribution point” can also be an antenna station or unit, for example for public WLAN. Such an antenna unit can be provided on its own (free-standing), but it can, for example, also be part of a street lamp or traffic light (attached or also structurally integrated).

In the fully assembled state, the antenna unit is then connected to the node by means of the data cable via the data cable branching point, data is transmitted to and from the antenna unit via the data cable, which converts the wired signal into a radio signal. This can also be a mobile radio signal, so the data user or distribution point can also be a mobile radio station (e.g. for 5G). Such a data user or distribution point can also include a technical building through which the data cable is led. The connection housing is then placed outside of this technical building in the area of the street, cf. the above notes.

In principle, the same advantages can arise when using the “antenna unit or station” as described above with reference to the buildings. If, for example, a district or a street is opened up (the road is dug up and an empty pipe run is laid, see the above comments on “existing” in detail), it is not only possible to move the office / residential building forward, but also to build it a public WiFi network. For this purpose, a respective connection housing can be placed, for example, next to a lantern, preferably directly next to the lamppost or a base. The lantern can then later take on a holding function for the antenna unit, and there is also a power connection available there (for the converter or converter). Appropriate placement of connection housings along the street, for example, with each or every nth lantern, allows the establishment of such a WLAN network. Then it does not have to be dug up again later, cf. the above notes. Even if the structure of the WLAN network has already been decided, the connection housings placed next to the lanterns can simplify the procedure. Analogous to the above description, the data cables can be laid in one operation from the node to the individual connection housings, and the actual installation on the individual lanterns can then take place gradually.

In a preferred embodiment, an empty pipe is thus laid between the data cable junction and the connection housing, which can then initially remain unoccupied or can be used to lay the data cable. For example, the empty pipe can 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 well guided.

In general, the empty pipe is laid at a height within the finished layer construction height of the street or floor, i.e. below the top edge of the finished surface layer (paving / slabs or asphalt). For example, it can run at least 10 cm, 20 cm, 30 cm or 40 cm below the latter, with possible upper limits at a maximum of 1.5 m, 1.2 m or 1 m. The empty pipe is preferably in the ground over the entire distance between the data cable junction and the connection housing, that is to say below the upper edge of the layer structure.

As already mentioned, in a preferred embodiment, the data cable is laid with an excess length in the connection housing when the empty pipe is occupied. When fully installed in the connection housing, an end section of the data cable should then have a length of at least 1 m, at least 2 m, 3 m, 4 m, 5 m, 6 m, 7 m, 8 m, 9 m and 10 m are further preferred lower limits. Possible upper limits can at most 30th m, 20 m and 15 m. This length becomes concrete between the entry point at which the Data cable from the empty tube enters the inside of the housing, taken to the end of the data cable (the end that lies outside the empty tube, that is, in a direction from the data cable junction to the connection housing).

In a preferred embodiment, the excess length, that is to say the end section, can then be temporarily stored in the connection housing, that is to say inside the housing. For this purpose, the end section is preferably made in the form of a loop, so that the minimum bending radii cannot be reliably undershot. For example, a cassette can be provided, that is, a storage surface with webs or hooks thereon, the spacing of which from one another determines the size of the loop shape. A suitable holder for the loop can be provided, for example, directly on the inner wall of the housing or as an otherwise integral part of the housing itself, but the cassette can also be provided so that it can be removed and reinserted. The connection housing can then have, for example, a receptacle for hanging or pushing or clipping the cassette.

The opening of the connection housing is preferably closed after the loop-shaped placement of the end section, that is to say the cover is put on or inserted. If the data cable is only stored for a short time and, for example, is moved to the building or user / distributor on the same working day, loop-shaped storage without closing the lid can also offer advantages, since the data cable can be somewhat protected inside the housing.

The connection between the connection housing and the building or user / distributor is preferably also carried out in the ground, particularly preferably an empty pipe (empty connection pipe) is first laid for this purpose, through which the data cable can then be pushed. In the course of subsequent occupancy, excavation has to be carried out again, but only on the property, not in public space (sidewalk / street), which means a correspondingly lower effort. In the case of a building, the connection housing is preferably placed directly on the property boundary.

The data cable or the end section is preferably laid from the connection housing to the building such that the end of the end section is then in the building. So that's where the line technology ends. In this case, the data cable then extends uninterruptedly from this inside the building via the connection housing to the data cable junction (usually beyond this to a node). “Uninterrupted” means without a connection point between them (especially without a splice point). This procedure can be advantageous, for example, insofar as no "more complex" work on the data cable is then required in the connection housing, that is to say, for example, no splicer has to be brought to the connection housing. In addition, the data cable in the connection housing can be somewhat "exposed" to environmental influences, which is why an uninterrupted course can be advantageous there.

In an alternative preferred embodiment, the connection housing is used to establish a connection point there. The data cable, which extends from the data cable junction to the connection housing, can also have a certain excess length there, for example at least 0.5 m, 1 m or 1.5 m, which can simplify the work. However, the excess length will then typically be less than in the previous example. B. be at most 5 m, 4 m, 3 m or 2 m.

If the building or the user / distributor is actually connected, another data cable is then laid between the building (user / distributor) and the connection housing, preferably in an empty connection pipe (see the above comments). This additional data cable is then connected to the data cable (which comes from the data cable junction), which can generally also be done, for example, by splicing. In this context, “connecting” should be read to establish a functional connection point over which data can be transferred. In general, the data in question can be Internet data in particular, which also includes telecommunications data such as e-mail etc. and telephony (VOIP), as well as television or entertainment data in general. As mentioned variously, the data cable is preferably a glass fiber cable, which can have a single or preferably a plurality of glass fibers. When connecting, in the case of several optical fibers, one optical fiber of one data cable is then connected to one optical fiber of the other data cable.

In a preferred embodiment, a connector is provided for connecting the data cable that comes from or via the data cable branching point and that for the building connection. The first-mentioned data cable can then be laid, for example, by the network operator, preferably initially without a plug, which simplifies or enables insertion / blowing. The data cable is then routed through the empty pipe without a plug at the end, preferably via the data cable junction in the direction of the connection housing (in particular by blowing in from a node, see above). The end laid in the connection housing is then prepared for the plug connection, for example a plug is spliced on.

The further data cable that is laid between the connection housing and the user / distributor or building is preferably prefabricated at one or both ends with a plug or attachment for attaching a plug. The connector can then be assembled at a pre-assembled end without any special tools, in particular without a splicer EP 2 482 109 A2 or the product DiaLink from Diamond. The pre-assembled end can be easily routed through the empty conduit without the plug part attached, then the plug part is put on and the plug connection can be made with the data cable (this is, for example, the procedure when inserting the additional data cable from inside the building). However, the additional data cable can also be inserted from the connection housing, the end with the removable and attachable plug part is then pushed into the interior of the building and assembled there. The end arranged in the connection housing can in this case also be equipped with a finished plug.

According to a preferred embodiment, a waterproof plug housing is arranged in the connection housing. To simplify the installation, it can be removable and reinserted, so a corresponding receptacle can be provided in the connection housing. The connection housing can also be designed for different applications, so it can be equipped both with a connector housing and with a cassette for receiving a loop-shaped data cable. Depending on the application, one or the other option can then be used.

Data cable plugs can be plugged together in a sealed manner in the waterproof connector housing. It preferably has an interior space which is sealed off from the outside and in which the data cable plug can be plugged together. In the housing there can be a penetration or entry point for each of the data cables, which, for example, each equipped with a sealing insert, can ensure a watertight entry of the cable into the interior.

An interior divided into at least two chambers can be particularly preferred, the chambers being accessible from the outside in each case via a separate closure. By opening a closure, a chamber can be opened and z. B. the data cable can be inserted, the other chamber can be opened by opening the other lock and the additional data cable can be inserted. The lock (s) can then be locked again. With the separate chambers, it is also possible, in particular if the data cables are installed with a time offset, to determine in whose area of responsibility which processes lie. After laying the data cable or other data cable, the corresponding opening is closed. If, for example, the corresponding opening is not closed properly when the additional data cable is laid, this assembly error can be clearly assigned.

In a preferred embodiment, the empty pipe and / or the building connection empty pipe is sealed towards the interior of the housing. If a data cable is laid through the corresponding empty pipe, a sealing element with a corresponding passage opening can be provided (this seals against the cable and against the empty pipe). If a data cable has not yet been installed, the empty pipe can be closed with a blind plug or closure. Sealing the empty pipes can, for example, prevent water from entering (towards the building or junction) or even be a barrier for creeping gas. Especially in connection with the "pull-out protection" described above, sealing can increase security because it prevents slipping or setting of the empty pipe, which could loosen the seal of the empty pipe. An integration of the empty pipe seal into the connection point can be particularly preferred, i.e. the empty pipe is attached and held there, and at the same time sealed (not or not only on the outer wall surface, but also on the interior).

In a preferred embodiment, the connection housing has a guide device in order to lead a data cable inserted from the data cable junction upwards out of the connection housing through the opening. This guide device connects to the entry point at which the data cable enters the interior of the housing. It is preferably fixed in its position on the connection housing, for example molded on or fastened. It is preferably attached to the connection point to which the empty tube is placed on the outside of the housing. The guide device can delimit a channel in which the end of the data cable is guided upwards when it is inserted into the interior of the housing. This channel can generally also be open, for example a U or. V-shaped, but it can also be formed by a short piece of pipe, for example a piece of corrugated pipe. A guide plate or the like can generally also be provided as the guide device; functionally, the end of the data cable is to be directed upward along the guide device. The guide device can thus prevent the data cable from getting caught in the interior of the housing or opening edge, etc., thus helping to avoid damage. The guide device is preferably plugged onto the fitting of the connection point inside the housing.

As already mentioned, the data cable junction is preferably located on an empty pipe run, namely it forms a branch thereof. The empty pipe string extends along several user or distribution points. In the case of buildings, it extends along several building areas that can already be built on (existing) or built on (new development area). A distance between the data cable branching point and the connection housing can be, for example, a maximum of 15 m, 10 m, 5 m or 3 m. B. are at least 0.5 m or 1 m.

In the existing building, when one or more of the buildings are being developed, an empty pipe can be laid directly from the respective data cable junction to the building, i.e. without a connection housing in between. This can be used for those households or owners who already decide on a corresponding data connection when opening up. In those buildings for which (for the time being) no data connection is desired, a connection housing is placed (and connected via an empty pipe from the data cable junction). In principle, several buildings could also be combined via a common connection housing; each building is preferably assigned its own connection housing. With regard to the options for placing the connection housing (directly on the building floor area or on the property boundary, etc.), reference is made to the above explanations; the same applies to the options for preparing the subsequent assignment (end section held in the form of a loop inside the housing, plug or initially only an empty pipe connection) .

In the new development area, all connections are preferably routed via a connection housing, preferably a separate connection housing is provided for each building. With a view to the subsequent construction work, this is then preferably placed on the property boundary. In principle, all the installation techniques discussed above (between the connection housing and the building then erected) also come into consideration here, in the connection housing the end section can then be placed in a loop or the connection can be prepared via a plug. In any case, the individual data cables can be laid in one operation from the node.

Also to be disclosed is a method for providing a data cable connection for a building (see the previous definitions), namely a connection to a data cable junction (see the previous definitions), wherein a connection housing is provided that has a housing interior , which is accessible from the outside via an opening in the connection housing, the connection housing being positioned between the data cable branching point and the building, specifically outside a building base area (cf. the previous definitions), but close to the building base area, e.g. at a distance of at most 1 m, preferably directly adjacent to it, the connection housing being placed at a vertical height which is within the finished floor structure height, but the opening remains accessible from above. The connection housing is preferably placed in such a way that it borders on an outer wall surface of an outer basement wall of the building.

In contrast to the variant or variants discussed above, in this case the connection housing is not necessarily arranged in the area of the street, that is to say in the layer structure of the street. Positioning in the layered structure of the street is possible (e.g. in the city, outer wall of the building / facade directly on the sidewalk), but not mandatory. The connection housing can, for example, also be laid on a plot of land in the ground, i.e. in the ground. In principle, this could result in the settlement problems described above, but the positioning on the building floor area creates a stabilization, the basement outer wall can therefore have a supporting effect (on the one hand, the connection housing is supported, on the other hand, the soil is also somewhat stabilized (to the side).

Positioning on the building floor area can also be advantageous, for example, to the extent that the connection between the connection housing and the building can then also be made entirely without digging. It is possible to drill through the outer wall of the building; this hole can then be used to route the data cable or other data cable (see above) into the building. For example, the borehole can be made above ground in the outer wall of the building, for example in the case of a basement-less building, or in the case of a building with a basement, also underground, i.e. in the basement outer wall. The (further) data cable can be routed to an above-ground hole, for example in a cable duct along the outer wall surface, and the underground hole can preferably extend directly into the connection housing.

The invention also relates to a use in which a connection housing is placed in a manner discussed above (horizontally in the area of the street, vertically at a height within the finished construction height of the layer structure of the street) and then the layer structure of the street is produced, cf. also the above comments. Part of the use can also be the subsequent opening of the cover (to Assembly purposes), then the opening can be closed again (with the lid).

Preferred embodiment of the invention

1 shows a connector housing device 1 with a junction box 2nd that from a lower part 3rd and a top 13 is composed. With the top 13 it is a street cap, the lower part 3rd is explained in detail using the 7-13 discussed. The connection housing 2nd delimits a housing interior 4th , which is divided into lower and upper parts 3rd , 13 accordingly in a lower section 4.1 and an upper section 4.2 structure. The connection housing is on the top 2nd an opening 5 on which the interior of the housing 4th is accessible, and the present with a lid 6 is closed.

The connection housing 2nd is with connection points 7.1 , 7.2 fitted. To the junction 7.1 is an empty pipe 8.1 scheduled that extends from an empty pipe string to the connection housing 2nd extends. To the junction 7.2 depending on the application and procedure in detail, an empty connection pipe 8.1 attached, which is then the connection housing 2nd connects to the distributor / user, for example a building.

The connection housing 2nd is in the layer structure outside the building 10th the street 15 placed (see also 2nd ) so that an upper edge 2.1 of the connection housing 2nd flush with an upper edge 9 of the layer structure 10th lies, which is sketched in the left half of the picture. An upper layer 10.1 can be, for example, the paving layer (sidewalk) or asphalt surface layer (road), the layer 10.2 underneath can be a bed or a binder course. The layers below 10.3 , 10.4 represent base layers. Will the connection housing 2nd positioned, is the location of the top edge 9 already known (fixed), even if the layer structure 10th is sometimes created much later.

2nd illustrates various options for an application in the inventory. In the situation shown here, a street is opened up by laying glass fibers. Are schematic as data user sites 16 four buildings 20.1-20.4 shown, each on a building floor area 21.1-21.4 stand. For the development of the side walk 22 broken open and a trench is dug, this is not shown in detail in the schematic supervision. An empty pipe string is in the trench 23 relocated, for each building 20.1-20.4 there is a respective data cable junction 24.1-24.4 . For illustration and orientation: in the illustration above the walkway 22 the respective plots extend 25th , in between is the property boundary 26 . In the illustration below the sidewalk 22 the road runs 27 that like the sidewalk 22 Part of the road 15 is.

In the course of the development of this street, only one owner has opted for an immediate connection, this is the building 20.4 . In this case, the data cable junction 24.4 to the building 20.4 directly an empty pipe 28 be relocated. The data cable is then laid through this.

For the buildings 20.1-20.3 , for which (for the time being) no connection is desired, a connection housing is created 2.1-2.3 placed. Furthermore, because the trench is currently being excavated, a respective empty pipe is being built 8.1.1-8.1.3 between the respective data cable junction 24.1-24.3 and the respective connection housing 2.1-2.3 misplaced, cf. also the synopsis with 1 for illustration. The trench can then be heaped up, and so can the layer structure 10th be restored.

Should later go to one of the buildings 20.1-20.3 but a data cable must be laid, at least the sidewalk 22 can no longer be dug up. Through the corresponding empty pipe 8.1.1-8.1.3 can via the respective data cable junction 24.1-24.3 from a node 29 can be blown out of a data cable, the lid can 6 of the connection housing 2nd opened and the data cable can be received there. At the building 20.1 the junction box sits 2.1 directly on the building floor area 21.1 , and not according to the main claim not in the area of the street, but on the property 25th . When placing directly on the building, it is no longer necessary to dig up, but only to drill through the outer wall of the building. With the buildings 20.2 , 20.3 must be a piece on the property for burial 25th be excavated, however, the effort for this is significantly less than for digging the sidewalk 22 .

Because of their positioning in the layer structure 10th the street 15 are the connection housings 2.2 , 2.3 kept stable, they cannot sag or tip over. This can prevent the empty pipes from slipping out 8.1 , 8.2 and thus prevent the data cable from kinking. A simply placed in the ground, not in base layers 10.3 , 10.4 enclosed connection housing 2nd would be unstable, however, especially fiber optic cables would break. The connection housing 2.1 is not in the layer structure 10th the street 15 provided, but due to the positioning directly on the building 20.1 stabilized.

The 3a, b illustrate how a data cable 30th through the empty pipe 8.1 inside the housing 4th is laid, only the top part for the sake of clarity 13 (the street cap) without the lower part 3rd is shown. The laying of the data cable 30th in this case there is an excess length, an end section 30.1 of the data cable 30th has from an entry point 31 inside the housing 4th taken away a length of around 10 m.

3b illustrates how this end section 30.1 then through the pre-or post-installed empty conduit 8.2 forwarded to the data user or distribution point 16, ie in the case of 2nd to the building. The end will be concrete 30.2 of the data cable 30th into the empty pipe 8.2 inserted, in the fully installed state it is then inside the building.

The state according to 3a (Advance to the connection housing 2nd ) according to the situation 2nd for the connection housing 2.1-2.3 can be produced in the same work process as the connection through the empty pipe 28 is placed. So it would be in each of the junction boxes 2.1-2.3 a data cable 30th brought forward, the corresponding end section 30.1 preferably in the form of a loop (risk of breakage). The bottom part 3rd can, for example, create additional space for this or also enable a division into several areas, cf. the introduction to the description. In summary, there is on the one hand the possibility that the connection housing 2.1-2.3 actually already with data cables during the advance 30th be equipped. On the other hand, however, is the positioning and connection alone via the empty pipes 8.1.1-8.1.3 sufficient that the sidewalk no longer has to be dug up.

4th illustrates an application in a new development area. Again, the sidewalk for orientation 22 and the roadway 27 the street 15 drawn in, this when laying the conduit 23 are not yet made. In this case, no buildings have been created (at least not yet completely), which is why only the building floor areas 21.1-21.4 are drawn.

When laying the conduit 23 is at every data cable junction 24.1-24.4 a respective empty pipe 8.1.1-8.1.4 to a respective connection housing 2.1-2.4 relocated. The connection housing 2.1-2.4 in this case are at the property boundaries 26 , but still on the side walk 22 placed. This will make the later construction work on the land 25th not disabled.

Then the first building is completed, for example on the building floor area 21.1 , is between the connection housing 2.1 and this building an empty connection pipe 8.2.1 relocated. From the junction 29 The data cable then comes from the data cable junction 24.1 and the junction box 2.1 relocated to the building. In the course of this, the other junction boxes are also connected 2.2-2.4 already laid the data cables, they can be analog there 3a be filed. It then advantageously only has to be at the node once 29 be handled.

5 illustrates an alternative to the procedure according to the 3a, b , namely the establishment of the user / distributor, in particular building connection via a further data cable 50 . This is in the junction box 2nd with the data cable 30th connected, in the present case by plugging together in a connector housing 51 . This has a sealed interior, in which the data cables 30th , 50 put together. Each of the data cables 30th , 50 enters the connector housing sealed 51 a. In principle, the connector housing can have an access opening; a variant with two separate access openings can be preferred 52.1 , 52.2 be. Every opening 52.1 , 52.2 is provided with its own closure, the opening 52.1 is used to insert the data cable 30th opened, the opening 52.2 to insert the data cable 50 .

6 shows another application, the connection housing 2nd again between a data cable junction 24th and a data user or distributor 16 is placed. Specifically, the latter is a radio unit 60 , namely a WLAN module. This is or will be used to provide a public WLAN network in a lamppost shown schematically here 61 arranged. When opening up the street, i.e. when the sidewalk 22 is dug up and the empty pipe string 23 the connection housing 2nd next to the lamppost 61 placed and over the empty pipe 8.1 with the data cable junction 24th connected.

The rest, along the street 15 arranged (not shown) lamppost is moved in an analogous manner, so it becomes a connection housing 2nd placed (not necessarily on every lamppost, for example every second can also be sufficient for sufficient network coverage). Then later the data cables from the node 29 blown in here, the data cables can be inserted into each connection housing in one work step, as described above (see "New Building") 2nd the connection of the respective radio module 60 can then be done gradually. The connection housing 2nd can also be used with lampposts 61 place if this is not yet with a radio module 60 are or should be equipped. The connection housing 2nd can significantly simplify retrofitting later (no digging up the sidewalk 22 ).

In the variant according to 6 can in the junction box 2nd analogous 5 be moved (plug connection), the variant according to the 3a, b (Looping through an excess length). The connection housing 2nd can be opened for this purpose, for example, and a connection can then be made through a housing wall of the connection housing 2nd and a base wall of the lamppost 61 be drilled. Of course, the variant according to 6 for example also with that according to 2nd can be combined in the development of the street 15 So both on the buildings not connected for the time being 20.1-20.3 as well as on lampposts 61 (or also traffic lights etc.) connection housing 2nd to be placed.

7 shows the lower part 3rd without a street cap, there are a total of four connection points 7.1-7.4 to recognize. An empty pipe can be attached to each of them 8.1-8.4 be set. With an appropriately equipped connection housing, several users / distributors can also be connected, for example, an empty pipe can be used for two buildings 8.1 , 8.3 between the empty pipe string and the connection housing, as well as another empty pipe 8.2 , 8.4 (Empty connection pipe) between the connection housing 2nd and the respective building.

The bottom part 3rd has a bottom wall 80 and a side wall 81 on, also compare the cut according to 8th . The side wall 81 delimits the lower section 4.1 of the housing interior 4th horizontally, i.e. in the horizontal directions 85 . The bottom wall delimits the interior of the housing 4th vertical, i.e. with respect to the vertical directions 86 downward. As with 10th Discussed in detail, fittings form the respective connection point.

On the inside of the housing interior there is a respective adapter piece for the respective fitting 87.1-87.4 also compare the detailed view according to 9 . The respective adapter piece 87.1-87.4 holds a respective guide device 88.1-88.4 , namely an empty pipe connected to the inside of the respective fitting housing. How out 7 as can be seen, these empty tubes extend upwards in a curved manner, the empty tubes end within the connection housing 2nd . Will be via the appropriate junction 7.1-7.4 a data cable from the outside 30th , in particular a fiber optic cable is blown in this in the corresponding guide device 88.1-88.4 up towards the opening 5 of the connection housing 2nd led, it can prevent tangling and thus damage to the glass fiber.

10th shows a fitting 100 that in the side wall 81 is set in one cut. The interior of the housing 4th is arranged on the left in the illustration, from the right is the buried conduit 8th inserted. With the fitting 100 is a plug-in fitting, the empty pipe 8th is secured against being pulled out by a claw after it has been pushed in completely (the empty pipe 8th is not shown in the fully but partially inserted state). The claw can be removed by pressing in a dismantling ring 101 loosen again, such fittings are commercially available in pipeline construction (the dismantling ring 101 presses the claw from the empty pipe 8th path).

The fitting 100 is in the side wall 81 set and based on a contouring of the opening (cf. 11 ) held against rotation. This is especially with a view to the assembly step after blowing in the data cable 30th an advantage if this against the empty pipe 8th is sealed. The fitting points to this 100 a sealing element 102 on that by tightening a union nut 103 axially compressed and thus close to the data cable 30th is pressed. For the sake of clarity, the data cable is 30th only on the left hand side of the fitting 100 shown in dashed lines.

The sealing element settles in the course of the axial compression 102 not just the data cable 30th , but also on an inner wall surface of the housing 104 so that the conduit 8th to the interior of the housing 4th is sealed there. The cap nut 103 is on a (not shown) thread on the outer wall surface of the housing 104 guided. It transmits the force to the sealing element via an inwardly set collar 102 with a washer in between 105 is provided for the distribution of the pressing force.

The housing 104 has, in one to the center axis of the empty tube 8th vertical section considers a contour. This contour is in the contoured hole 116 in the side wall 81 held against rotation. This turns the fitting 100 when tightening the union nut 103 not with what simplifies assembly (a fitter has to enter the connection housing from above 2nd reach in). The fitting 100 is in 10th from the right into the hole 116 in the side wall 81 inserted (without the union nut 103 , this is then screwed on). There are two locking rings as a pull-out protection 106.1 , 106.2 provided, which are clipped on and the fitting 100 so opposite the side wall 81 spread out. The circlips 106.1 , 106.2 are each opened a bit, which according to the oblique view 9 for the circlip 106.1 can be seen.

Like the synopsis of 9 and 10th illustrated, is in the fully assembled state on the respective union nut 103 a respective adapter 87.1-87.4 set (this is in 10th not shown for the sake of clarity). The adapter 87.1-87.4 sits positively on the respective union nut 103 , has one of the cap nuts 103 corresponding inner contour. This can, after blowing in the data cable 30th , by turning the respective adapter 87.1-87.4 the respective union nut 103 rotated and the sealing element 102 be pressed in the manner described above.

11 shows the lower part 3rd in a single representation, i.e. without the fittings. This lower part 3rd is made of plastic by thermoforming. The side wall 81 is viewed in a horizontal section, see also 12th , contoured shaped. It is in indentation areas 110 offset inwards, in bulge areas 111 outward. Relating to a revolution around a vertical axis 115 follow the indentation and bulge areas 110 , 111 alternating with each other, which creates a stable shape.

Also in the indentation areas 110 the connection points 7.1-7.4 placed, namely holes 116 in the side wall 81 provided for inserting the fittings. These are at the top of each indentation area 110 arranged where the side wall 81 at an angle to the vertical axis 115 extends. Accordingly, there is also a central axis 117 of the empty pipe placed on the respective fitting 8.1-8.4 angled to the upward vertical direction 86 (compare 8th , there are two central axes 117 shown).

At the top of the base 3rd runs the side wall 81 in a flange 120 outward. The road cap is placed on this and over holes 121 screwed.

12th shows a horizontal section through the lower part 3rd , only a lower section of it is shown. This again leaves the successive indentation and bulge areas 110 , 111 detect. Furthermore, it can be seen from this illustration that the bottom wall 80 is slightly raised in a middle area, also compare the cut according to 8th . In the bulge areas 111 forms the bottom wall 80 one stand space each 130 , please refer 13 (This illustrates the area with which the lower part 3rd on a Support plate 135 sits on, compare 1 ). In the bulge areas 111 is the bottom wall 80 each with a hole 136 provided that the mounting on the support plate 135 and / or the discharge into the connection housing 2nd water can serve.
