Description

The present invention relates to an installation system with an insertion mechanism. Furthermore, the invention relates to a telecommunication system.

In order to achieve the desired high data transmission rates in Germany and worldwide in the future, a fiber optic network is to be built right into individual buildings. For this purpose, an empty pipe network made of so-called microducts is generally installed first. Such pipes have an outer diameter of approx. 7 to 20 mm and each run continuously from a junction box to the respective building. The ends of such a microduct are sealed with an end cap or a single pass seal. After the completion of this laying work, the fiber optic cables are blown into the individual pipes using compressed air at 10 to 15 bar, either immediately or at a later date. For this, the executing company needs an employee at the distribution box, from which the cable is blown into the pipe using a blowing device, as well as another employee in the respective building where the pipe ends. The employee there removes the pipe plug, accepts the blown-in cable and splices individual fibers in the connection box. The annular space between the pipe and the cable is then sealed pressure-tight in the building. The corresponding fibers must then be connected to the backbone cable at the distribution box. This process is often divided into two dates, with a team of employees taking over the blowing in and only later splicing the fibers in the building and at the distributor, i. H. be connected.

The disadvantage of the above-described technique is that during the period in which the cable is being blown into the pipe, all residents must allow access to their respective buildings. If access to a building is not possible, blowing in has to be carried out at considerable additional cost. In addition, depending on the procedure, an employee has to enter the building at a later point in time to splice the cable.

This is where the invention comes in, which has set itself the task of overcoming the above-described disadvantages of the prior art and providing an installation system with which a telecommunications cable can be blown into the cable duct quickly, error-free and inexpensively in one operation. leading to the respective building is possible. In addition, the installation system should have a simple structure, be inexpensive to provide, and be easy and safe to handle when installing the telecommunications cable.

A further object of the invention consists in specifying and providing a telecommunications system which can be installed with such an installation system. The first task is solved by the subject matter of claim 1.

It was recognized within the scope of the present invention that an installation system for establishing a data transmission connection between a first station and a second station by means of a telecommunications cable, in particular by means of a fiber optic cable, completely solves the task if it is provided that the installation system is an installation box Cable duct having a first end and a second end, an auxiliary duct having a first auxiliary duct end and a second auxiliary duct end, a telecommunications cable having a first telecommunications cable end (121) and a second telecommunications cable end, the cable duct (130) having its second end connected to the installation box and wherein the auxiliary pipe is fluid-tightly connected at its second auxiliary pipe end to the cable pipe at its end portion at the second end, and comprises an insertion mechanism, wherein the telecommunication cable with a length L in the installation box and an end portion at the first telecommunications cable end protrudes into the duct by an insertion length L(E), the insertion mechanism comprising a driver and a trigger, the insertion mechanism being in frictional engagement with the telecommunications cable.

The above-described object according to claim 1 of the present invention makes it possible to set up a telecommunications system in a simple manner using the installation system, this being possible in a simple, fast, error-free, cost-effective manner and with a minimum of personnel.

In particular, a single person can install one or a plurality of second stations, for example associated with or located in different buildings, the telecommunications systems to the stations without requiring access to the buildings.

Especially when setting up the supply of telecommunications services in new areas with a large number of newly built residential buildings, the technology according to the invention is far superior to the work processes previously carried out for this purpose, in terms of simplicity, speed, accuracy and the personnel required for installation sonal use and the associated installation costs.

In particular, it is possible with the present invention to enable the telecommunications cable to be safely blown into the cable duct, since the blowing-in process is supported by the insertion mechanism, so that even under difficult conditions, such as e.g. B. a winding route, as mentioned above as disadvantages of the known technology, the injection process can be done easily, safely and professionally.

The present invention can be designed in a particularly advantageous manner such that the installation system is characterized in that the insertion mechanism comprises an insertion roller set and/or an insertion push belt set.

By providing that the insertion mechanism includes an insertion roller set and/or an insertion push belt set, the process of blowing the telecommunications cable into the cable duct can be supported by actively inserting the telecommunications cable into the cable duct, so that the telecommunications cable can be safely and professionally blown into the cable duct.

In a particularly advantageous further development of the present invention, it can be provided that the installation system is designed in such a way that the insertion mechanism is driven electrically and/or by spring force and/or by fluid pressure.

This measure makes it possible for the insertion mechanism to be driven in a simple manner, which is beneficial to the safety of the drive, the required speed of insertion and the cost minimization of the system.

With particular advantage, the present invention can be designed in such a way that in the installation system the trigger of the insertion mechanism is a pressure switch that switches when the pressure is increased.

The design of the installation system in such a way that the trigger of the insertion mechanism is a pressure switch, which switches when the pressure increases, makes it possible to start the drive of the insertion mechanism in a targeted manner when the blowing-in process takes place, i.e. compressed air is present in the auxiliary pipe and in the cable duct and thus a pressure increase is triggered there.

This allows the telecommunications cable to be blown into the cable duct more easily, since the insertion mechanism is only put into operation when the blowing-in process starts, so that the insertion mechanism supports the blowing of the telecommunications cable into the cable duct, thus ensuring safe blowing-in.

In a particularly favorable embodiment of the present invention, it can be provided that in the installation system the auxiliary pipe is connected to the cable pipe in a fluid-tight manner by a T-piece.

A T-piece is readily available, inexpensive, and can be connected to pipes quickly and safely in a fluid-tight manner, thereby enhancing the installation system according to the invention.

It can prove particularly advantageous in the present invention if it is provided that the installation system is designed in such a way that the second telecommunications cable end of the telecommunications cable is connected to the second station for data transmission.

As a result of this measure, it is not necessary to carry out connection work in the building, which in turn would necessitate a time-consuming and cost-intensive deployment of personnel.

It can be provided with great advantage in the present invention that the installation system is designed in such a way that the length L of the telecommunications cable is greater than the length of the cable duct from its first end to its second end.

This means that there is always a sufficient reserve of cable length for the telecommunications cable during the installation work so that the connection work can be carried out quickly and safely even in complex construction conditions in buildings at the second station, but also at the first station, without problems caused by cable lengths that are too short comes.

In the context of the invention, it can be very favorable if the installation system is designed in such a way that the insertion length L(E) of the end section of the telecommunications cable at the first telecommunications cable end is approximately 30 to 120 cm.

This enables the telecommunications cable to be safely blown into the cable duct, which allows for quick, safe and cost-effective installation.

In a preferred further development of the present invention, it can be provided that the installation system is designed in such a way that the cable duct is connected to the first station at its first end.

This measure allows the use of the telecommunication cable to be started immediately.

It can prove to be extremely advantageous in the present invention if the installation system is designed in such a way that the installation box and/or the cable duct and/or the auxiliary pipe and/or the T-piece consists of or contains a polymer material.

Here, the polymeric material may be a thermoplastic, and in particular a reinforced thermoplastic.

A polyamide is preferred here, in particular a polyamide that is glass fiber reinforced, since this is particularly tough.

Thermoplastics from the group of polyolefins, polyethers, polycarbonates and polyesters are also preferred.

This measure allows a particularly stable and durable installation system to be provided.

The installation system is to be designed in such a way that a sealing element seals the cable duct against the installation box.

This ensures that the telecommunications cable is pulled out of the installation box through the sealing element and into the cable duct. The sealing element prevents compressed air from penetrating the installation box and thus not being available for the blowing-in process, but allows the telecommunications cable to enter the cable duct largely unhindered.

Furthermore, the installation system provides for the auxiliary pipe to be connected in a fluid-tight manner with its second auxiliary pipe end to the cable pipe at its end section at the second end.

In the case of the present invention, it can be found to be very favorable if the installation system is designed in such a way that the installation box and/or the cable duct and/or the auxiliary pipe and/or the T-piece are produced by a molding process, in particular by an injection molding process and/or or through an extrusion process and/or through an additive manufacturing process, such as a 3D printing process.

Due to the production in an injection molding process, the installation box and/or the T-piece can be provided in large quantities, reproducibly and with dimensional accuracy, which means that the costs for this can be reduced.

The cable duct and/or the auxiliary duct can be easily manufactured in an extrusion process.

Manufacturing in a generative manufacturing process, such as a 3D printing process, can significantly reduce manufacturing costs, especially for small quantities, and technical changes can also be made immediately in this way.

In particular, provision can be made for the installation box and/or the cable duct and/or the auxiliary pipe and/or the T-piece to be produced entirely or partially using an additive manufacturing process, for example a 3D printing process.

For this purpose, a three-dimensional model that can be read by a data processing machine can advantageously be used for the production.

The invention also includes a method for generating a data processing machine-readable three-dimensional model for use in a manufacturing method for an installation box and/or a cable duct and/or an auxiliary pipe and/or a T-piece. In this case, the method also includes, in particular, entering data representing an installation box and/or a cable duct and/or an auxiliary pipe and/or a T-piece into a data processing machine and using the data to create an installation box and/or a cable duct and/or to represent an auxiliary pipe and/or a T-piece as a three-dimensional model, the three-dimensional model being suitable for use in the manufacture of an installation box and/or a cable duct and/or an auxiliary pipe and/or a T-piece. Also included in the method is a technique in which the data input to one or more 3D scanners, which operate either on touch or without contact, with the latter applying energy to an installation box and/or a cable duct and/or an auxiliary duct and/or a T-piece is emitted and the reflected energy is received, and wherein a virtual three-dimensional model of a service box and / or a cable duct and / or an auxiliary pipe and / or a T-piece is created using computer-aided design software.

The manufacturing process can be a generative powder bed process, in particular selective laser melting (SLM), selective laser sintering (SLS), selective heat sintering (SHS), selective electron beam melting (Electron Beam Melting - EBM / Electron Beam Additive Manufacturing - EBAM) or solidification of powder material by means of binders (binder jetting). The manufacturing process can be a generative free space process, in particular build-up welding, wax deposition modeling (WDM), contour crafting, metal-powder application processes (MPA), plastic-powder application processes, cold gas spraying, electron beam melting (electron beam welding - EBW) or melt layering processes such as fused deposition Modeling (FDM) or Fused Filament Fabrication (FFF). The manufacturing process can include a generative liquid material process, in particular stereolithography (SLA), digital light processing (DLP), multi-jet modeling (MJM), polyjet modeling or liquid composite molding (LCM). Furthermore, the manufacturing method can include other generative layer construction methods, in particular Laminated Object Modeling (LOM), 3D screen printing or light-controlled electrophoretic deposition.

The second object of the present invention, the specification of a telecommunications system, is solved by the subject matter of claim 5.

It was recognized within the scope of the present invention that a telecommunications system comprising a data transmission connection between a first station and a second station by means of a telecommunications cable, which is installed with an installation system as described above, rises above the prior art and the advantages described above can use positively.

The installation with the installation system according to the invention takes place as follows: A first station is to be provided, which is a distribution station, for example, in order to supply a certain number of buildings with telecommunications services from there. In the simplest case, a trench is to be dug from the first station to a building into which the duct and auxiliary pipe are to be laid, the duct extending from the first station to the building and then ideally into it. The auxiliary pipe is ideally laid in the same way.

A T-piece is to be installed in the building near the second end of the cable duct, which is to be connected fluid-tight to the second end of the auxiliary duct.

An installation box is installed in the building at the second end of the conduit and populated with a length L of telecommunication cable.

Such an installation box can be a closed box with a base plate and a cover, but such an installation box can also just be a base plate that is equipped with the telecommunications cable.

The telecommunications cable is then to be arranged in such a way that an end section at the first telecommunications cable end protrudes into the cable duct with an insertion length L(E). The second end of the telecommunication cable is to be connected to the second station in the building.

By blowing compressed air into the first auxiliary pipe end of the auxiliary pipe, which should be located at or at least close to the first station, the compressed air flows through the auxiliary pipe to the second auxiliary pipe end and there through the T-piece into the cable duct.

The insertion mechanism included in the installation system includes an insertion roller set and/or an insertion push belt set. The insertion mechanism is driven electrically and/or by spring force and/or by fluid pressure. The drive of the insertion mechanism is set in motion by a trigger, the trigger being a pressure switch which switches when the pressure increases. The insertion mechanism is in frictional engagement with the telecommunications cable whereby driving the insertion mechanism inserts the telecommunications cable into the duct.

Due to air friction on the end section of the first telecommunications cable end protruding into the cable duct, which is inserted into the cable duct with an insertion length L(E), this is also carried along in the direction of the first end of the cable duct, in particular by the support provided by the insertion mechanism. The compressed air can escape at the first end of the cable duct.

The telecommunications cable has been pulled out of the installation box through the sealing element. The sealing element prevents compressed air from penetrating the cable duct into the installation box and thus not being available for the blowing-in process, but allows the telecommunications cable to enter the cable duct largely unhindered.

When the first telecommunications cable end arrives at the first end of the cable duct, it can be accepted there by the installation personnel and connected to the local telecommunications infrastructure in the first station.

The blowing of the compressed air is then to be stopped, which also stops the operation of the insertion mechanism.

Since the second end of the telecommunications cable is already connected to the second station, the telecommunications system is then immediately operational.

In an alternative laying technique, it can be provided that the cable duct is routed directly past the building to another remote station or to a selected remote end point. At the building, the duct is cut, two connections are made and the connection is made in the house as described above, with an end portion at the first telecommunications cable end protruding into the duct with an insertion length L(E).

The telecommunications cable can then be blown in by supplying compressed air from the end of the cable duct at the other station or at the chosen end point, after which its end can be closed with a cap, for example.

This also creates a backup situation if the building needs to be retrofitted with additional telecommunications cables, which can then be positioned in the cable duct from the other station or from the selected endpoint.

The advantage of the present invention is, in particular, that the structural measures described above make it easier to handle when installing a telecommunications cable, because a house connection can be established quickly, safely and inexpensively with a minimum of personnel, which greatly facilitates the work of the installing personnel .

Further important features and advantages of the invention result from the dependent claims, from the figures and from the associated description of the figures.

It goes without saying that the features mentioned above and those still to be explained below can be used not only in the combination specified in each case, but also in other combinations or on their own, without departing from the scope of the present invention.

A preferred embodiment of the invention is shown in the figures and is explained in more detail in the following description.

• 1 eine schematische Darstellung eines ersten Installationssystems;
• 2 eine schematische Darstellung eines zweiten Installationssystems;
• 3 eine schematische Darstellung eines Telekommunikationssystems.

For this show:

• 1 a schematic representation of a first installation system;
• 2 a schematic representation of a second installation system;
• 3 a schematic representation of a telecommunications system.

In the 1 a first installation system 100 is shown.

The installation system 100 for establishing a data transmission connection between a first station 210 and a second station 220 by means of a telecommunications cable 120, in particular by means of a fiber optic cable, comprises an installation box 110, a cable pipe 130 with a first end 131 and a second end 132, an auxiliary pipe 140 with a first auxiliary pipe end 141 and a second auxiliary pipe end 142, and a telecommunications cable 120 having a first telecommunications cable end 121 and a second telecommunications cable end 122.

The telecommunications cable 120 is accommodated in the installation box 110 with a length L.

An end section 125 at the first telecommunications cable end 121 with an insertion length L(E) protrudes into the cable duct 130 .

The cable duct 130 is connected to the installation box 110 with its second end 132 , a sealing element 138 sealing the cable duct 130 against the installation box 110 .

The auxiliary pipe 140 is connected in a fluid-tight manner with its second auxiliary pipe end 142 to the cable pipe 130 at its end section 133 at the second end 132 .

The installation system 100 also includes an insertion mechanism 150, which is designed here as an insertion roller set. Two counter-rotating rollers are designed for this purpose, which are set in motion by a drive 152 when the trigger 153 provided on the cable duct 130 starts the drive 152 by increasing the pressure in the cable duct. An existing signal connection between the trigger 153 and the drive 152 is in the 1 not shown, but this signal connection can take place in the form of a pulse through a cable or through an electromagnetic signal or through an optical signal. The drive 152 then drives the insertion roller set to frictionally insert the telecommunications cable 120 into the duct. To do this, the rollers of the infeed roller set rotate in such a way that the 1 shown upper roller rotates clockwise while the lower roller rotates counter-clockwise. The drive 152 functions electrically, with a battery or an accumulator and an electric motor being provided for this purpose. After the telecommunications cable 120 is installed in the conduit 130, the insertion mechanism 150 can remain in the installation box or can be removed and reused at any time as needed.

Because insertion occurs only when pressure is applied, the insertion mechanism 150 does not consume power when at rest. It can thus be equipped with a battery which still has the full or nearly full capacity for the insertion of the telecommunications cable 120 even after several months, for example if there are delays in construction or installation. There is therefore no need for a building-side power connection, which in most cases could not be made available.

In the 2 a second installation system 100 is shown.

The reference symbols in 2 correspond to those from 1 .

The installation system 100 differs from that in FIG 1 illustrated and described in that a reel 115 is installed in the installation box 110, on which a section of the telecommunications cable 120 is wound.

The second telecommunications cable end 122, which ends on the reel 115 in the installation box 110, has a plug connection at its end.

After installation, ie the blowing of the telecommunications cable 120 into the cable duct 130 - its principle in the 3 is shown - the connection of the second telecommunication cable end 122 with the plug connection attached there can easily be made with the aid of a connecting cable 128 to the second station 220, in that the connecting cable 128 is connected to the plug connection - for example by means of a plug which is complementary to the plug connection.

The installation system 100 also includes an insertion mechanism 150, which is designed here as an insertion push belt set. For this purpose, two push belts running in opposite directions are formed, which are set in motion by a drive 152 when the trigger 153 provided on the cable duct 130 starts the drive 152 by increasing the pressure in the cable duct. An existing signal connection between the trigger 153 and the drive 152 is in the 1 not shown, but this signal connection can take place in the form of a pulse through a cable or through an electromagnetic signal or through an optical signal. The driver 152 then drives the insertion pusher band set to frictionally insert the telecommunications cable 120 into the duct. For this purpose, the bands of the insertion push band set move in such a way that the 1 the upper band shown rotates clockwise, while the lower band rotates counter-clockwise. The drive 152 functions electrically, with a battery or an accumulator and an electric motor being provided for this purpose. After the telecommunications cable 120 is installed in the conduit 130, the insertion mechanism 150 can remain in the installation box or can be removed and reused at any time as needed.

In the 3 a telecommunications system 200 is shown, which using the installation system 100 from the 1 has been installed.

The reference signs in the 3 correspond to those from the previous figures.

The telecommunications system 200 is installed using the in the 1 shown first installation system 100 has been constructed.

It is understood for the person skilled in the art that even with the 2 A telecommunications system 200 can be installed in the second installation system 100 shown, but this is not further shown here.

By blowing compressed air into the first auxiliary pipe end 141 of the auxiliary pipe 140, the compressed air at the second auxiliary pipe end 142 reaches the cable duct 130 via the T-piece 135 and, due to air friction, it reaches the end section of the first telecommunications cable end 121 that protrudes into the cable duct 130 and is equipped with a Insertion length L(E) is introduced into the cable duct 130, this is taken along in the direction of the first end 131 of the cable duct 130, where the compressed air can escape.

The telecommunications cable 120 has been pulled out of the installation box 110 through the sealing element 138 and into the cable duct 130 . The sealing element 138 prevents compressed air from entering the installation box 110 and thus not being available for the blowing-in process, but allows the telecommunications cable 120 to enter the cable duct 130 largely unhindered.

When the first telecommunications cable end 121 is at the first end 131 of the conduit 130 arrives, it has been accepted there by the installing staff and connected to the local telecommunications infrastructure in the first station 210, at the same time the compressed air supply is terminated.

The insertion mechanism 150 comes to a standstill because the trigger 153 no longer transmits a signal to the drive 152 .

Since the second telecommunications cable end 122 is already connected to the second station 220, the telecommunications system 200 is then immediately ready for operation.
