Description

The This invention relates to distributors for any cables, such as copper cables, Fiber optic cables that are easy to install.

• – Primärbereich, d. h. Verkabelung der Gebäude eines Standortes untereinander, auch als Campusverkabelung oder Geländeverkabelung bezeichnet. Der Primärbereich umfaßt den Standortverteiler zur Aussenanbindung des Standortes, die Gebäudeverteiler und die Kabel zwischen den Gebäudeverteilern (Primärkabel) eines LAN. Im Primärbereich sind große Entfernungen, hohe Datenübertragungsraten sowie eine geringe Anzahl von Anschlusspunkten bestimmend. Hier ist bspw. die Glasfaser als Übertragungsmedium wegen ihrer geringen Dämpfung, großen Bandbreite (und damit Einsparung vieladriger Kupferkabel) und der elektromagnetischen Unempfindlichkeit besonders geeignet. Zudem findet eine galvanische Trennung statt und es kann auf einen aufwendigen Potentialausgleich zwischen den Gebäuden verzichtet werden. Ebenfalls praktiziert wird eine Anbindung über die Telefonleitung mit VDSL, sofern eine entsprechende Schaltung möglich ist. Verwendete Kabelarten: Glasfaserkabel, Kupferkabel.
• – Sekundärbereich ist die vertikale Stockwerkverkabelung; die Verkabelung der Stockwerke eines Gebäudes untereinander – auch als Steigbereichverkabelung bezeichnet. Der Sekundärbereich umfaßt die Stockwerkverteiler oder Etagenverteiler (Switches) und die Kabel vom Gebäudeverteiler (Serverraum) zu den einzelnen Stockwerkverteilern (Sekundärkabel). Verwendete Kabelarten sind (nach DIN) meist: Glasfaserkabel.
• – Tertiärbereich ist die horizontale Stockwerkverkabelung, also die Verkabelung innerhalb der Stockwerke eines Gebäudes – auch als Etagenverkabelung bezeichnet. Der Tertiärbereich umfaßt die Kabel vom Stockwerkverteiler zu Sammelpunkten (die Installation mit Sammelpunkt wird auch als vierstufige Verkabelung bezeichnet) oder direkt zur Anschlußdose (Tertiärkabel) die auch ein Teil dieser Tertiärverkabelung ist. Häufig verwendete Kabelarten sind: Twisted-Pair-Kabel, bei Fiber to the Desk auch Glasfaserkabel.

For a better understanding of the invention, first of all its field of application is explained:
In the universal building cabling (European standard EN 50173-1 Application Neutral Cabling Systems (November 2002) of the European Committee for Electrotechnical Standardization (CENELEC) distinguishes between 3 areas:

• - Primary area, ie cabling of the buildings of a site with each other, also referred to as campus cabling or area cabling. The primary area includes the site distributor for external connection of the site, the building distributors and the cables between the building distributors (primary cables) of a LAN. In the primary area, long distances, high data transmission rates and a small number of connection points are decisive. Here is, for example, the glass fiber as a transmission medium because of their low attenuation, large bandwidth (and thus saving vieladrigen copper cable) and electromagnetic immunity particularly suitable. In addition, a galvanic isolation takes place and it can be dispensed with a complex equipotential bonding between the buildings. Also practiced is a connection via the telephone line with VDSL, if a corresponding circuit is possible. Cable types used: Fiber optic cable, copper cable.
• - Secondary area is the vertical floor cabling; the cabling of the floors of a building with each other - also referred to as riser area cabling. The secondary area comprises the floor distributors or floor distributors (switches) and the cables from the building distributor (server room) to the individual floor distributors (secondary cables). Cable types used are (according to DIN) usually: fiber optic cable.
• - Tertiary area is the horizontal floor cabling, ie the wiring within the floors of a building - also known as floor cabling. The tertiary area includes the cables from the floor distributor to collection points (the installation with collection point is also referred to as four-level cabling) or directly to the junction box (tertiary cable) which is also part of this tertiary cabling. Frequently used cable types are: Twisted-pair cable, Fiber to the Desk also fiber-optic cable.

Fixed cabling (BASIC-Link, also referred to as installation cable) is permanently fixed between the floor distributor and the collection point and the shorter loose cabling (CHANNEL link or patching cables) in the tertiary area between the collection points and the workstation boxes. Thus, the Consolidation Point is the connector within an installed link. It can also be provided more collection points, but only so many that the limits of the links are not exceeded. For this purpose exists in the EN 50173 a separate calculation formula. The collection points are strategically placed in the room. Shunting cables can be connected to them as required and workstations connected to the network. In a new, changed distribution of end cables in offices, other / additional work cables are connected to the distributor and routed to the various workstations

Distributor, also called "consolidation point" or consolidation point ( DIN EN 50173-1: 2002 also collection point according to the European standard EN 50173-1 for Application Neutral Cabling Systems (November 2002) of the European Committee for Electrotechnical Standardization (CENELEC), are particularly suitable for so-called structured cabling or zone cabling, also known as Universal Building Cabling. The collection point should be at a central point in a room (distribution box). The EN50173 provides a common set-up diagram for cabling for different services (voice or data). Structured cabling is part of the technical infrastructure of a property and is divided into primary, secondary and tertiary education. The corresponding North American standard TIA / EIA 568 also deals with such cabling. They serve the decentralization of the distribution functions and offer individual solution packages for workplaces through collection point for energy and data network in each room by eg: Installation in the false ceiling; Supply of workplaces via room columns; Wiring via floor outlets or floor tanks. It can be supplied by clustering of workstations, the junction box in room columns or room distributor via patch cables, thereby reducing the cost of cable laying work done.

A "Consolidation Point" is a part of the connection hardware for the connection between the permanently installed horizontal cables from the floor distributor and the movable horizontal cables to the workstation / work station sockets, which are the interface to the universal wiring system If the tanks / cans need to be relocated, only the cable between the collection point and tank / box must be relocated and possibly re-measured who the. A rallying point that represents a central point in a room supplies patch cords. He is, so to speak, a small, subordinate distributor. A collection point should be at least 15 meters from the floor distributor (cable length) to minimize the mutual effects of both elements.

Advantages of the Consolidation Point include:
a transition from fixed to flexible wiring; an application-neutral cabling; Clear installation; Possibility of rapid change of use; needs-based decentralized adaptation of the infrastructure; Reliability; Spare corners can be planned, measuring points close to the workplace are possible.

The Workstation connection box connected to the patchcable should at a location accessible to the user, for example, on the wall, be installed in a duct or floor tank system. Functional A collection point provides a simple means of reorganization horizontal cabling in open-plan offices, to make a connection between the fixed wiring and moving Stations, such as moving office furniture, create. The collection point is not a data management point - this finds in the network distributor, the patch panel, instead of using a fixed Cable is connected to the collection point.

at Office changes will be rewiring frequently one of the big cost factors. Collection points serve to excess To avoid cable lengths. At Sammelpunkteinsatz must significantly less data cables are laid in the tertiary area and thus the effort for laying, track construction decreases and fire protection. Through consistent application of the so-called "cable sharing "can be over the same number of connections Save 20% cable mass in the tertiary area. It is believed, that through collection point concepts about half the investment costs for the electrotechnical infrastructure can be saved, moves can be very time Saved and the work safety can be increased. Finally, the interior design of office space enhanced by avoiding cable lengths lying around. By a flexible and fast adaptation of energy and data cabling with changes in the room layout and the use of space Collection points highly recommended.

In Considering the rapidly advancing technology, constant change requests to existing networks and thus to the requirements of cable networks It is necessary to develop simple collection points which are cost effective and with little effort the connection of communication cables enable.

collection points are fields which are connecting, distributing and maneuvering serve connections. Each distributor contains connection components for incoming and outgoing cables: Each junction box is assigned a separate connector on the distributor. distributor There are different embodiments, they are different in terms of both numbers and facilities for plug-in devices. As a rule, there is a collection point from in-line connection components of the same Category.

A growing importance of the use of optical fibers and also higher quality - d. H. technically better cables in communication, for example in the transmission of broadband Signals, leads to ever more complex cabling. The cabling are often partially implemented in optical fibers, which should be connected to each other. At the same time, though also copper lines available - for example separate telephone networks od. Like.

in the The collection point ends the external cables and are via couplings connected to the workstation cables. Distributors are with many Couplings equipped, which, for example. Connection of several external Fiber optic cables to allow the patch cable.

typically, Offices are executed in a 7.5 × 7.5 m grid and include collection points in housings, for example, in raised floors or suspended ceilings or on the wall hang. The connection components at the collection points allow easy attachment of additional data cables, if that is desired for a job.

Known Distributor, which is a grounded case with a metal bottom plate with cable fastening devices for incoming and outgoing Cable and a coupling device have the disadvantage that when changing the type of cable - eg. At the transition from copper wires to optical fibers - this one Distributor was no longer operational and of a completely new distributor had to be replaced.

Of the Removal of a fully installed distributor is usually not possible without other, in the same area built-in distributor also expand - already the expansion of a panel is very expensive - the Expansion of uninvolved panels leads to further significant Workload and downtime associated with the cable cabinet Network.

This resulted in considerable time losses during installation, the clarity and verifiability of the installation was after assembly of the distributor not given anymore.

It is therefore an object of the invention, an easily accessible Fiber optic distributors to create, post-installation, inspection and repair in a simple manner.

The The object is achieved by a distributor solved with the features of claim 1. advantageous Further developments emerge from the dependent claims.

Thereby, that the distributor is modular and only Einzelmoduln the same are exchanged, if a subsequent installation carried out is providing without dismantling the distributor base components new connection component holder possible.

By The modular structure of the Consolidation Point for a variety of Applications are used, for example, for different protection classes (eg IP); and according to DIN, EN, VDE standards. The structure offers a variety of Anund expansion options, including the Components of the Consolidation Point must be flexible - in Height and width adaptable and screwable. It is important that all parts of the Sammelelpunkes conductive with each other keep in touch.

Prefers is the collection point of a conductive material, such as Metal sheet to perform equipotential bonding and also to have EMF protection against interference fields.

It may be that different types of plugs and cables in the Distributor should be included. In this case, you can several different terminal component holder on the support element be releasably attached. These can, for example, divisible Having connection component holder in the after opening a part of the connection component inserted and then the Holder closed by fastening the connection components becomes. The fact that a simple arrival and replacement of the Connection components on the support element possible It is easy to do without replacing the entire manifold Architecture that houses various types of connecting elements has. Thus, significant conversion measures, the example. For the subsequent installation of mixed networks can be avoided. It is also possible, by simply replacing the holder to install a new system.

Thereby Installation times, which in networks the Most of the costs cause, are significantly shortened.

at In one embodiment, the carrier element is a essentially rectangularly bent flat material blank with a support surface and a mounting surface, a cutout for the connection component holder, one side of which is detachably mounted on the base and its substantially perpendicular to this holding area with facilities for detachable attachment of at least one connection component holder for the same or different connection components, such as plugs, sockets, couplings, is set up.

Typical cable terminal components are selected from the group: RJ45, 2xRJ45, VarioKeystone ^® cable connector, Tera RJ45, 2xRJ45, Tera, EC7, SubD9, SubD15, ML, etc., as well as transition couplings, but by no means limited to these.

If Cables with other technical specifications are required because the network is being retooled or an error in this module present - can the connection components disconnected in the connection component holder, the connection component holder be removed, and by a new connection components be replaced for the other network, due to the Fact that the base is fixed so that the Terminal component holder removable without removing the base is, the base itself remains in place. This may cause a disassembly of the distributor are avoided. Depending on the requirement after removing the terminal component holder with the coupling elements also other coupling elements with appropriately adapted connector component holders be used.

For the mounting on the floor, wall or ceiling is usually the support plate mounted on a base plate, with protection against pressure, humidity and dust a lid can be put on.

If now another cable should be retrofitted, This is also possible in a simple manner. First is the connection component holder after the stuck from the cable dismounted, possibly even the carrier element can be replaced become, whereby the basis does not have to be dismantled itself. As a result, significant installation times, which at Networks cause the bulk of the cost to be shortened.

• – Vorsehen einer Basis;
• – Anbringen eines Trägerelements;
• – Anbringen von Anschlußkomponentenhaltern entsprechend den Anschlußkomponenten der Verkabelung am Montagehalter des Trägerelements;
• – Auflegen der Kabel und Befestigen der Kabelanschlußkomponenten in den Anschlußkomponentenhaltern; und
• – Anstecken der jeweiligen abgehenden Leitungen an die Verbindungselemente des Verbindungselementhalters, und
• – Festlegen der Leitungen an einer Befestigungszone des Verteilers.

A method of installing such a distributor thus includes:

• - Provide a basis;
• - Attaching a support member;
• - Attaching terminal component holders according to the connection components of the wiring to the mounting bracket of the support member;
• - placing the cables and securing the cable connection components in the terminal component holders; and
• - Connecting the respective outgoing lines to the connecting elements of the connecting element holder, and
• - Fix the cables to a mounting zone of the distributor.

there can also terminal components and / or connection component holder be replaced at the distributor. It is also possible, to exchange the carrier itself.

The distributor according to the invention can be installed, for example, by installing the installed connection component holders with their connection components on the mounting section 14 the carrier element 12 be attached - regardless of whether the base 10 now installed in a housing or not. After attaching the installed connector component holder 26 . 28 At the base, the terminal component holder can be used without dismantling the base 20 be reduced. By attaching the connection component holder 26 . 28 in their recesses 17 Connection components of the respective cable of the network can be fixed, a patch cable can be plugged in the usual way.

ever Upon request, after removing the terminal component holder with the coupling elements and other connection components correspondingly adapted connection component holders be used.

If now another cable should be retrofitted, This is also possible in a simple manner. First becomes the terminal component holder after removing the cable couplings dismantled, leaving the base due to the remaining fixture, After that, any existing locking of the at least one Connection component holder solved and the component holder pulled out to the back. You can now by appropriate replaced new connector component holder with new cables become. After installation, if necessary, the carrier element attached to the base, possibly newly locked to the base and the Connection component holder with the corresponding connection components the clutches arranged therein are mounted.
