DESCRIPTION

Conductive bar set

The invention relates to a set of conductive bars according to the preamble of patent claim 1.

In the assembly of exhibitions and scenarios, modular cross-section systems are used to delimit the space, as well as to install lighting, acoustics and media technology. In the Web page
www.traversen- discount.com represents such a system. The crossbar system consists of multiple crossbars, where appropriate, of different lengths that can be assembled, thus making it possible to perform a complete crossbar structure in situ. In this case, the electric lines for lighting and / or acoustics and / or media technology, as well as, where appropriate, the data lines are installed separately by means of cables that are fixed on the crossbars.

The installation of individual cables is expensive and often also insufficient in terms of safety technology. For technical safety reasons, cross-sectional constructions like these are also electrically grounded. Wo 2010/144261 A1 also known as a system of crossbars asf realized.

From US 7 819 676 B1 a current distribution system in the form of a conductive bar is known. Here the housing itself is grounded. This conductive bar is a non-modular but only derivable system that cannot be used in the assembly of exhibitions and shops.

A conductive bar is known from US 5 151 043 which only has pluggable current contact elements.

From the document UK 2 344 001 A a conductive bar is known which has plug ends for the electrical connection and extension of the conductive bar. In this case, the housing is grounded but the system is extensible but not modular.

From DE 692 04 010 T2 a conductive bar with electric lines is known inside a closed housing that extends longitudinally, surrounding the housing to the electric lines and disposing at its ends plug-in contacts. A conductive bar of this type is suitable for mechanical fixation in a set of crossbars such as the one known for the assembly of exposures. For this, this conductive bar includes integrated mechanical fasteners, electrically conductive and grounded, equipped with grounding conductors.

In this regard, the crossings for the assembly of shops and exhibitions are also known by DE 19938970 A1 and DE 20 2004 018 016 U1.

In particular, the mechanical fixing of conductive bars in metal crossings determines, for safety reasons, that they must be grounded.

For this purpose, it is necessary to additionally ground the crossbars or establish an electrically conductive connection and capable of charging a maximum short-circuit current foreseeable to the grounding conductor or to ground. Since this constitutes a separate installation phase, but of considerable importance in terms of security technology, it cannot be forgotten due to human error.

From DE 20 2004 018 016 U1 it is also known the possibility of also integrating a conductive bar inside the crossbar.

In this case, the conductive bar or the set of conductive bars is integrated into one of the so-called belt tubes, so that the belt tube is grooved along the entire length. This known integrated busbar is a major drawback. As a consequence of the longitudinal grooving, the tube is clearly weakened in its static and with it also the crossbar. The invention is based on the task, on the one hand, of considerably simplifying the laying of cables in a set of conductive bars for application in an assembly of exhibitions and shops and, on the other hand, of also considering the technical aspects of security for power distribution and grounding without weakening the static. The proposed task is solved with a conductive bar of the generic type according to the invention by means of the features of claim 1. Other advantageous configurations are indicated in the dependent claims.

The essential idea of the invention is to use the conductive bar in the assembly of exhibitions and shops as an electric line system for a crossbar system composed of assembled crossbars, so that the conductive bar is also modular and can be plugged in as its own traverse system, the electrical plug-in contacts of the conductive bar arranged and fixed in the traverse being approximately in the same plane as the mechanical coupling points of the traverses and that by fixing the conductive bar or the conductive bar housing ( 2) in the traverse (1) a forced earthing of the traverse system is obtained. With the conductive bar or the set of conductive bars according to the invention that develops practically parallel to the crossbar, the statics of the crossbar system are not weakened. Thanks to the arrangement of the plug-in contacts on the front faces, the conductive bar according to the invention is also modular and plug-in just like the crossbar system. However, forced earthing is essential according to the invention of the traverse through the fixing elements between the

conductive bar or the set of conductive bars and the crossbar. The fixing elements are grounded directly inside the busbar housing or through a grounding of the busbar housing itself. Accordingly, the solution of the task results in a modular current distribution system that can be easily installed, as well as a safe grounding of both the conductive bar or the conductive bar housing of the connectable consumer device, as well as the own travesano. In this way, it is never possible to forget the relevant grounding for the safety of the set of crossings.

For the rest, a conductive bar means the arrangement of conductive bars in a housing. Normally these conductive bars are also called current distribution slats and are composed of an elongated housing in which the printed circuits or the conductive bars or the cables that are attached to contacts of plug boxes arranged in the housing of a ribbon are arranged of current distribution of this type. The simplest embodiment of these power distribution slats is the transportable multiple plug box.

In another considerably advantageous configuration it is proposed that each set of busbars of the line system additionally include data lines and that data signal connections are also distributed along its length. That is, data lines are also installed inside this conductive bar. This means another clear increase in functionality. Line connections, as well as now, data connections can be connected in parallel evenly through the plug-in contacts placed on the front side of the busbar to the busbar. Therefore, the system is modular both for the distribution board for strong current, as well as for the distribution box for data signals.

For this reason, in another advantageous configuration it is proposed that the connections for data signals be XLR contacts for DMX signal transmission, or XLR for ADAT transmission or RJ45 network connectors, for example, for Artnet, etc.

Another advantageous configuration is that each conductive bar has at least one signal amplifier or an integrated bus signal amplifier. In this way, a complete and modular integral solution is obtained in which no type of external signal amplifier is necessary anymore. At each point of a crossbar system equipped with these busbars there is also a high level data signal.

In another advantageous configuration it is provided that the dimensions of the conductor bars fixed in the crossbars and of the crossbars themselves are adapted to each other, so that when assembling the crossbars, the pluggable contacts of the conductor bars fit into each other by establishing contact. Thus the busbar system is similarly modular as is the crossbar system.

Inside the conductive bar, single-phase alternating voltage can be developed, but also three-phase alternating voltage. In three-phase solutions, the different phases are distributed in the different low-voltage plug connectors such as plug boxes or connections. Therefore, in this way it is also provided that each busbar of the line system includes low voltage plug connectors distributed along its length as grounded plug boxes or CEE or Powercon or Harting connectors.

In another advantageous configuration it is proposed that each conductive bar include automatic fuses integrated in the conductive bar in addition to the power fuse protection for the individual fuse protection of the low voltage plug connectors or the grounded plug boxes . In this way it can be limited in terms of the load EACH INDIVIDUAL socket, so that it can be guaranteed that the current carrying capacity of the socket itself, as well as the main lines that are developed in the conductive bar itself do not overload as a result of a plurality of actively ACTIONED plug boxes. This total protection is still carried out additionally through the external power fuse protection. This also constitutes a fundamental safety feature, which cannot be found in this way in usual conductive bars.

The above-mentioned embodiment is, therefore, possible, by sizing the protection powers of the automatic fuses respectively so that these are less than or equal to those of the desired current load capacity of the respective strong current connections (plug boxes ). Certainly this seems trivial, but in this case of very special application it is of great importance.

Finally, the system is also configured in accordance with the protection standards, so that the contacts of the line system, as well as the set of conductive bars, are made protected against dust and splash proof in accordance with IP 44.

An exemplary embodiment of the invention is described in the drawing which is described in more detail below.

It is shown in

Figure 1 shows a perspective view on the busbar assembly. The conductive bar includes an elongated housing 2 in which printed circuits are arranged as conductive bars that are not shown here in more detail. In case of 1 phase alternating current, these are phase L, the neutral conductor N and the grounding line.

In the case of 3 phase alternating current, these are phases L1, L2 and L3, as well as the neutral conductor and the grounding conductor. In the case mentioned last, the three phases can be sub-distributed in different sockets. The conductive bar 2 aqm shown is part of a modular system of many conductive bars that are fixed in the manner described first in the crossbars 1 and which are then mounted (assembled) with the crossbars 1 in a crossbar system. In this example, the crossbar is made up of four asf called belt tubes. These are joined by sleepers, for the sake of clarity not represented here in greater detail, or to a kind of lattice and bracing.

The conductive bar 2 at the bottom is practically turned upwards from the position shown theref and pushed between the belt tubes. Then, in a transverse tube 1 'aqm shown, a mechanical connection is established between the fixing element 5 and, at the other end of the conductive bar, the fixing element 4.

Then, the conductive bar 2 is arranged and fixed in the position shown here in stripes inside the crossbar 1. In this case, the electrical plug-in contacts are together in approximately the same plane as the mechanical coupling points of the crossbars .

Here, the conductive bar 2 is connected through the fixing elements 4 and 5 to the respective cross member 1. The fixing elements 4 and 5 are metallic, that is electrically conductive and are connected inside the conductive bar or the busbar housing 2 to the grounding conductor. Since the crossbars are also metallic, the forced earthing according to the invention of the crossbar is therefore obtained. It is connected after installation to the power grid and to a data signal system. Plug-in contacts are arranged on the front face 3. Since according to the invention not only strong current must be distributed, but data signals must also be transmitted from cross-section to cross-section and accessible there in any way, lines are also implemented in the conductive bar of data. These contact the data signal pins 31 on the front face, while the strong current lines are connected to the contact pins 30. In this case, the plug-in contacts 3 are configured as a set of male (male) plug-in contacts. . The complementary plug-in contact (female) 3 'is then placed on the opposite front side of a straight conductive bar like this. Thus, the conductive bars can be plugged directly into each other.

In this case it is important that in this embodiment the contact plane of the conductive rod is approximately equal to the plane of mechanical connection of the traverse 1 so that the movement of mechanical union and the movement of electrical union are so equal that when joining the different Crossbars also connect electrical plug-in contacts at the same time.

The housing of conductive bars includes, for its upper face 2b, the fixing elements 4 and 5 and, for its lower face 2a, the plug boxes 10 and the signal connections 11 distributed.

Figure 2 shows the upper face 2b of the busbar housing 2. Aqm are arranged along the longitudinal extension of the busbar housing, both grounded plug boxes 10 or any form of possible connectors of low voltage plug, as well as data connections or data connection contacts 11. The provision of automatic fuses that separately protect the different plug boxes in the way described above is not shown in greater detail, so as to limit the power connected by a plug box that cannot generate any load of the conductive bar above the limit of current load capacity of the printed circuits or of the conductive bars arranged in the housing of conductive bars.

Inside the busbar housing, data signal lines are also developed that are transmitted from bar to bar through contacts 31.

To refresh data signals, integrated signal amplifiers or signal refreshments are implemented in the conductive bars. If the busbar is mounted on the crossbar, the electrical connections 10 and 11 preferably point upwards, that is, inside the crossbar, according to Figure 1.

Examples for the interconnection of conductive bars are shown in Figure 3. The assembly generally proceeds so that the respective busbar housing 2 is fixed on the respective crossbar 1 through the fixing elements 4, 5. The crossings are then assembled and in a synchronized manner the electrical through connections of the plug connectors 20 and 21. In this case it is especially important that a transconnector like this also includes in a set of plug connectors 20, 21 respectively common, both transconnectors for strong current, as well as for data signals. For the realization of all degrees of freedom of assembly, the plug connectors can be configured both as straight transconnectors, as well as T-connectors.

However, a more efficient and simple interconnection of the busbars 2 is shown in Figure 4. Here the system of plug-in male and female contacts is used. That is, on a straight 1 busbar, by

a front face is a plug-in contact 3 male and on the opposite side a plug-in contact complementary female. Thus ^ it is possible to plug one busbar into the other. In the lower part of the drawing of Figure 4 a conductive bar is shown that develops in a T-shape. In this case, the distribution of female plug-in contacts and male plug-in contacts is carried out so that a connection of the left male plug-in contact, on the right a female plug-in contact connection and in the T-piece also a female plug-in contact connection.

In this way it is possible to carry out the additional connection to other conductor bars or assemblies of crossbars and conductor bars.
