Description

Conductive busbar system.

The present invention relates to a system of conductive bars for luminaires according to the preamble of the claim 1, as well as to a connecting element.

Conductive or row bar systems bright find application in many different ways, since in Comparison with fixed or recessed installation luminaires offer a high degree of flexibility for the individual project of lighting structures for specific requirements. The systems Conductive bars are composed of several individual elements that join together according to a modular principle, so that all The training can be adapted to the premises to be illuminated. Luminous row systems are known by which no only two-dimensional structures can be formed but also three-dimensional

The basic structure of a bar system conductors is formed by the mounting strips that are composed  to form the desired structure and that serve to support the power supply and control lines different luminaires For this reason, the mounting strips have of presenting a high level of stability and are generally metallic They can have different forms, for example they are known Mounting strips with Y profile or A profile. But the most extended are the U-shaped mounting strips, which with its central arm are fixed to a support, for example the roof of a local or the wall of a local. The mounting strips are fixed the different luminaire modules, being usually the length of an individual mounting strip a multiple of the Length of the luminaire modules. For example they are offered mounting strips with a length of 3 m or 4.50 m if the modules of the luminaries have a length of 1.50 m. This kind of integer length relationships are chosen to simplify planning during the design of a system luminous rows.

To ensure the power supply for the luminaires the corresponding pipes pass through or inside of the mounting strips. Additionally they can be provided in addition to the power supply lines also other conduits for the transmission of signals from control, thereby obtaining the possibility of being able to control and individually dim the different luminaires if a adequate control system.

In a known luminous row system that distributed by the applicant under the name "System of luminous row ZX ", the pipes pass through the interior of U-shaped mounting strips, such as continuous wiring, with bypass sockets at regular intervals which correspond to the length of the modules of the luminaires The bypass sockets are fixed under pressure in the mounting strips, where some beading fit behind the corresponding projections of the mounting strips, directed inland. At the points provided by the shots of Bypass the luminaire modules can be mounted, placing them for this on the open mounting strip towards below, and fixing them. The establishment of contact with conductors take place through a touchdown element located in the modules of the luminaires, which presents contacts of connection that when placing the luminaire module on the strip mounting fit into holes in the bypass socket, putting thus in contact with the corresponding threads. The modules of the luminaires also have rotating levers that rotate after placing those, thus dealing with mechanical fixation on the mounting strips.

In the busbar system before described the luminaire modules can only be placed in those points that are given by the bypass sockets, since otherwise there is no possibility of establishing a contact electric. To avoid these limitations and obtain with it greater flexibility for the arrangement of the different luminaires, it have developed busbar systems that have a current conductor profile supported by mounting strips. This current conductor profile is made up of bodies elongated of a non-conductive material, usually plastic, for accommodation of threads for feeding current and / or for the transmission of command signals with slots that run in the longitudinal direction of the mounting strips and that are accessible from one side to contact establishment. Since in this case the threads nudes are exposed at least in the length of a individual current conducting profile body, towards the side of contact establishment, can be placed within this field a luminaire at any point, so that there is greater freedom for the project and implementation of the row system bright.

The length of each of the bodies of the current conductor profile is adapted to the length of the mounting strip. This means that when assembling two strips of assembly the two conductive profiles of stream. This connection is problematic since in this area it is It is necessary to ensure that it is not possible to establish a contact involuntary with a thread. The corresponding standard requires  than a 1 mm thick test wire extended in a straight line I can't trip over one of the threads. In a bar system conductive known, the connection therefore takes place in these interfaces using a so-called serial connector, which by itself It offers no possibility to establish a contact. A system corresponding is known for example from DE 195 39 958 A1.

US 3,1818,102 further describes a system of conductive bars that allows the establishment of contact with the current conductor profile by a consumer even at the interfaces between two adjacent mounting strips. For this, the current conductor profile is made with tubular current conductors that on one side have a longitudinal groove through which the consumer contacts can penetrate inside the current conductors. In the interfaces there are special design connection elements, which on the one hand connect the current conductors and on the other hand also allow the establishment of contact. This system therefore allows the free arrangement of consumers in the mounting strips, although the manufacture of tubular current conductors used for this is relatively complex and
expensive.

The objective of the present invention is therefore both facilitate a technique that in a system of conductive bars for luminaires with a current conductor profile allow simple way to establish contact even at the interface between two mounting strips.

This objective is solved by a system of conductive bars that presents the characteristics of the claim 1, or for a joint element according to the claim 13. The connecting element used according to the invention in the busbar system is characterized in that It has grooved recesses that correspond with the grooves of the current conductor profiles, in which is placed in each a metal connector to which they can connect the wires to be connected from both sides each other, and that by means of a groove shaped groove shape an accessible area for contact establishment. He establishment of the contact in the area of the connecting element has therefore place because the connection contacts of a module luminaire to be connected to the busbar system is puts in contact with the upper faces of the connectors metallic that form the contact establishment surface. The joint element consisting of a non-conductive material, with the metal connectors, close the gap between the profiles Current conductors of two mounting strips and ensures that the entire length of the busbar system can be fixed freely a luminaire module, since in the transition zone the metal connectors form the setting surfaces of contact for the contacts of connection of the module of the luminary. The shape of the recesses of the connecting element, at same as the shape of the grooves of the current connector profile, is chosen in such a way that there is protection against required contact.

Some improvements of the invention They are the subject of the subordinate claims.

The metallic connectors can present by example an elongated plate for contact establishment as well as elastic U-shaped elements arranged in both ends of it, by means of which the threads are tightened to the introduce them and compress against the setting plate of Contact. This also ensures that during a thermal expansion of the current conductor profile, which is plastic, the threads do not move bulging and possibly They may even deviate. If the conductive profiles of current are inside the mounting strips in U-shaped, the mechanical connection between two strips of contiguous mounting preferably using a short strip U-shaped joint that fits respectively half by half on the two mounting strips. The element or elements of union are arranged for this in the side arms of the union strip. The union strip can also present, next to one or both ends, elastic tabs that in assembled state fit behind holes provided both in the mounting strips as in the connecting strip. In this way  it is guaranteed that two mounting strips joined together by means of a union strip they are held together in a simple way but releasable, since to release them you simply have to exercise pressure on the elastic tabs.

A refinement of the invention deals with the configuration of the current conductor profile arranged in a individual mounting strip. The plastic bodies that form the Current conductor profile are usually manufactured by extrusion. This procedure has a drawback, since with he can only manufacture plastic parts of a precision limited, since the plastic cools very quickly after out of the extrusion nozzle, and change shape. The consequence of this is that the bodies of the conductive profiles One-piece current can only be manufactured up to one Some degree of complexity. In particular, it is extremely expensive the manufacture of very long bodies.

By refining according to the invention describes a possibility of manufacturing the profile current driver considerably more economically and easily adapt it to the length of a power strip mounting. This is made possible because a conductive profile of current consists of a minimum of two wire support elements assembled together, of a non-conductive material, which present grooves for the accommodation of the threads. The elements of thread clamping are made in its extreme sections of such that when assembling them with protrusions that are in their ends fit together in such an overlapping way that in the area of union between two support elements of the thread form channels corresponding to the grooves, and open to the side of the contact establishment. These channels are accessible only from the side of the contact establishment, but by the rest are enclosed just like the grooves of the support elements of the thread and the connecting element, so that The safety standard is also met in these areas. Of this mode is created along the entire length of a conductive bar a possibility of establishing continuous contact but safe.

Through the modular construction that allows assemble the current conductor profile based on several individual support elements of the threads, you have the possibility of offering mounting strips of the most lengths diverse, for whose provision with a current conductor profile just use support elements of the threads of a single length, since the current conductor profile can be adapted to the length of the mounting strip simply by varying the number of thread support elements. The consequence of this is a noticeably lower production expense. It is also not necessary manufacture long and expensive plastic parts in one piece. The thread support elements can be produced for example by the injected casting process, considerably Easier to master and more economical.

In current conductive profiles based on plastic parts, it should be especially taken into account that they may be exposed to thermal radiation that should not be neglected, especially in the vicinity of reactances for luminaires arranged near or especially within mounting strips. The consequence of this is that the plastic parts expand, or when they are not exposed to radiation, they can contract. For this reason, the fact that the coefficient of expansion of the plastic is approximately 10 times greater than that of the metal is especially problematic, so that the different support elements of the threads can vary significantly in length, while the supported threads instead by the current conductor profile they maintain practically the same length. For this reason, the support elements of the threads can have at their ends locking elements which, when assembling two support elements of the threads, fit together and limit the relative displacement or separation in the longitudinal direction to a predetermined movement clearance. If the support elements of the wires cool and contract, then they are removed to a predetermined maximum distance at which protection against contact still exists; if they get hot, they get closer to each other. In this way, regardless of temperature, a direct current conductor profile is formed. The support elements of the threads preferably have a length of about 500 mm, the allowable clearance being whereby two support elements of the adjacent threads can be moved relative to each other about 8 mm, which is sufficient to the temperature differences that usually appear in bar systems
conductive

Another improvement is that the contact establishment of the wires by a module luminaire inside a U-shaped mounting strip be more simple to perform For this, the luminaire module presents a contact setting item with multiple contacts from connection, the element of establishment of contact on the mounting strip from the open side, to then partially rotate it, preferably about 45 °. Turn the connection contacts into the grooves of the current conductor profile and contact the threads. For this the contact establishment element it may be preferably carried out in such a way that at least one of the connection contacts is height adjustable. Given the the wires arranged at different heights in the conductor profile of current fulfill different functions, you can get a optional contact establishment by scrolling Connection contacts This offers the possibility to assign to the luminaires connected to the busbar system about different functions, for example use some of the luminaires only as emergency luminaires. In the element of contact establishment may also be provided blocking elements that when turning and setting thread contact additionally fit behind parts protruding from the mounting strip, which results possible at the same time mechanical fixation on the power strip mounting. This way it can be done by a simple maneuver, both an electrical contact establishment and also the mechanical fixation of the luminaire module.

Next is about describing with greater detail the present invention using the attached drawing. In this one show:

The basic element of the bar system conductors shown in Figure 1 is a mounting strip 1 U-shaped, metal or sheet, which with its central arm 2 can be fix using fasteners not shown on a support, for example to the ceiling of an enclosure or to a wall of an enclosure. He closing of the open bottom face of the mounting strip 1 se performed using a coating profile 5. In the case represented, this coating profile 5 is part of a luminaire module fixed to the mounting strip, being shown in Figure 1 only the setting element of the luminaire module contact in the form of a control swivel 50, but not its remaining components, for example the luminaire or the corresponding control or operating device, which can be an electronic reactance (EVG). Interior space of the mounting strip 1 serves in this case also as a space of accommodation for the operating equipment of the luminaires Those areas of the mounting strip 1 in which no luminaire modules are located, they can also be closed by aesthetic and safety reasons with a coating profile 5, fixing the cover profile 5 by fitting to pressure or interlocking.

In the present example there are arranged in the inner faces of the two side walls 3a and 3b of the strip assembly 1 some current conductive profiles that are formed by several support elements of the threads 10, of plastic and assembled together, each comprising two wings 10a and 10b with several slots 11 for housing the threads 6. On the right side wing 10a are arranged five 6 threads, while six threads pass on the left side 6.

The threads 6 arranged in the right side wing 10a may have for example the following functions, following the top-down order:

Emergency current 1

Emergency current 2

Neutral conductor of the standard network

D1 = Control conductor for control of lights

D2 = Control conductor for control of lights.

The functions of the threads 6 arranged in the left side wing 10b are for example:

         \ vskip1.000000 \ baselineskip
      

Both the number of threads used and their provision and function has been represented only by way of example and can be adapted to individual needs.

By establishing contact with corresponding threads 6 can be assigned a certain function to the luminaire that is connected, for example the luminaire It can be used as emergency light. Through the use of two control lines for light control you have the possibility of forming a bus system with these two conductors by means of which a plurality of luminaires can be activated using digital command instructions, as already Meet other more complex lighting systems.

Establishing contact with threads 6 takes place through several connection contacts 53 and 54 arranged in the rotating socket 50, which penetrate the corresponding grooves 11 and settle against the threads 6. To allow a simple and variable contact establishment, the connection contact 53 is in the rotating socket 50, so height adjustable by means of a support element 55. By means of a simple displacement of the support element 55 can be assign the desired function to the luminaire connected to the busbar system. For grounding it is planned furthermore a wire element 62 driven by a groove 63 of the swivel socket 50, whose end 62b makes contact with the thread bottom left 6 intended for grounding. The structure detailed and operation of the setting element of Contact 50 will be explained later in more detail. The power supply for the busbar system it can take place for example by means of a rotating socket properly adapted that is positioned in the longitudinal direction in Any point.

The secure hold of the two side wings 10a, 10b of the wire support element 10, takes place by middle of several guide arms 12_ {1} - 12_ {4} that penetrate the corresponding guide grooves 4_ {1} - 4_ {4} of the strip Mounting 1 U-shaped. The various support elements of the 10 wires aligned forming a current conductor profile, introduced during assembly in the longitudinal direction in the mounting strip 2. On the back side of the side wings 10a and 10b, that is on the opposite side to the establishment side contact slots 11 are several support struts 16 that provide stable support for slots 11 within the mounting strip 1, so that when establishing contact these Don't be pushed back. This favors a establishment of secure contact of wires 6.

The union of the two lateral wings 10a and 10b takes place at regular intervals by means of bridges of union 13 which are arranged in the central arm 2 of the power strip assembly 1. The connecting bridges 13 also have arms of support 15 that protrude down and that together with one arm horizontal 14 protruding in the horizontal direction of the lateral wing right 10a form an additional hollow space 8. This hollow space It can be used to accommodate additional cables or conductors. In addition to this, the horizontal arm 14 also has the objective of prevent contact setting element 50 from being placed on mounting strip 1 in an inverted position, as well as It will be explained later.

The shape of the slots 11 of the elements of thread holder 10 has been chosen so that it is guaranteed protection against contact, as will be explained to then using Figure 2. Here it is again represented the mounting strip 1 with a conductive profile of current arranged inside, although now without the socket swivel 50. The aforementioned safety standard provides that wires arranged in the current conductor profile must not be so uncovered that a 1 mm thick test wire 7 can impact straight on a thread 6 under tension. In the representation, the most convenient entry angle for the test wire 7 corresponds to the wire 6 provided below to the left. As shown in Figure 2, the widths, depths and opening ways of the slots 11 are sized in such a way that even with the entry angle more small, test wire 7 cannot establish contact with any of the wires 6. This avoids a involuntary contact with wires 6 and the corresponding one is fulfilled safety standard

Before going on to explain the way of joining according to the invention between two mounting strips and the corresponding current conductive profiles, will be treated previously through Figures 3 to 6 the specific configuration of the support elements of the threads 10 that form the profile current conductor, presenting for this Figure 3 a support element of the threads 10 seen in perspective. The essential elements of the support element of the threads 10 are the two side wings 10a and 10b presenting the slots 11 for the accommodation of the threads. They are linked together by two junction bridges 13. In this way it can be formed additionally, using the horizontal arm 14 and the support arms 15 protruding from the connecting bridges 13, the hollow space 8 before mentioned that can be used for the accommodation of others conductors or cables useful for the lighting system. In both side wings 10a, 10b are also also arms guide 12_ {1} to 12_ {4} which, when placed fit into the recesses 4_ {1} to 4_ {4} of the mounting strip 1. The representations in Figure 3 and in Figure 4 show the wire support element 10 immediately after its manufacturing. To insert the wire support element 10 on the mounting strip 1 the side wings 10a and 10b are lowered around the two folding points A and B, 90º down (see Figure 4), and then slide inside the mounting strip 1, whereby the arrangement is obtained represented in Figures 1 and 2.

The two lateral wings 10a and 10b present in its ends some projections 17 and 22 respectively, with whose help two support elements of the 10 threads that are assembled. At one of the two extremes they have also provided with locking heads 18 that only allow separate two support elements from the threads 10 that are assembled, in the longitudinal direction until a certain separation maximum, so that a current conductor profile composed of several support elements of the threads 10 is flexible in longitudinal direction, and therefore the length variations of the different support elements of the threads 10, which are made of plastic, due to differences in temperature

This should be explained by Figures 5 and 6, which show on a larger scale two support elements of the assembled threads, on the one hand from the establishment side of the contacts (Figure 5) and on the other from the back side opposite (Figure 6). The parts that correspond to the first element of support of the threads 10_ {1} carry the subscript 1 while the elements belonging to the second support element of the threads 10_ {2} present the subscript 2. After assembling the two support elements of the threads 10_ {1} and 10_ {2} these they fit together overlapping in such a way that by means of a projection 17_ {1} of the first thread support element 10_ {1} thus as a projection 22_ {2} of the second support element of the wires 10_ {2} forms a channel 23 that joins the slots 11 together of the two support elements of the threads 10_ {1} and 10_ {2}. Like the slots 11, all channels 23 formed of this mode in the junction zone are only accessible from the side of contact establishment, that is from above, but not from a side. This also ensures protection against contact required in the area of channels 23.

From the representation of Figure 6 you can deduce that the two locking heads 18_ {2} only allow  separate the two support elements from the threads 10_ {1} and 10_ {2} until a maximum separation is given because the locking projections 19_ {2} protruding laterally from the ends of locking heads 18 come to settle against butt walls 20_ {1}. To do this, this maximum separation default, as well as the length of the projections 17 and 22 that they fit together, are sized so that even during maximum separation between the two elements of Thread support 10_ {1} and 10_ {2} are still formed channels 23 described above, and protection against the Contact. Moreover, the ends of the two elements of thread support 10_ {1}, 10_ {2} can approach each other  so much so that its two front faces 21_ {1} and 21_ {2} reach butt facing each other. This means that the two wire support elements 10_ {1}, 10_ {2} can be move relative to each other with some slack, but that contact protection is obtained at all times. From this way the length variations of a certain support element of the threads 10 that expands by example because of a higher temperature, or that contracts in case of lower temperatures. This is especially important. due to the fact that unlike the support elements of threads 10, which are made of plastic, the threads 6 proper that they are housed there cannot make length variations so large, since the temperature coefficient of the metal is only 1/10 of the plastic expansion coefficient. For one length of about 500 mm for an individual support element of the threads 10, the allowable clearance by which you can mutually move adjacent support elements of each other threads 10, can be approx. 8 mm

The support elements of the threads 10 represented can be made of plastic easily by an injected smelting process, with which its manufacture is very economical On the other hand, it is enough to manufacture support elements of the threads 10 in only a single length, since to adapt the current conductor profile thus formed to the different lengths of the conductive bars, it is only necessary to adapt the number of thread support elements 10 used, which in turn significantly reduces the manufacturing cost of all the system. The protrusions that fit together and the elements of Lock may also have different settings.

When using the thread support element described above, you could imagine first riding all mounting strips of a busbar system, and equip them only later with the current conductive profiles necessary, being then possible to establish contact throughout of the entire length of the busbar system. But busbars already finished are usually distributed equip, in which there is already a conductive profile of full current with the threads placed inside.

In accordance with the present invention, it is achieved also in the junction areas between two mounting strips a continuous contact establishment, using the connecting element that has grooves in the form of grooves corresponding to the grooves of the conductive profiles of current and that are additionally accessible from both sides front of the connecting element.

This is first represented in a way schematic in Figure 7. To establish the mechanical bond between two adjacent mounting strips 1, a connecting strip is used 30 cuts, also U-shaped, on which they slide from both sides the mounting strips 1 to be joined together. An improvement that is not represented, ensures that two mounting strips 1 joined together by means of a connecting strip 30 are held together in a releasable way. To do this, each strip of assembly 1 can have one or more on top holes The connecting strip 30 is then also provided with the corresponding holes through which some elastic tabs The elastic tabs fit behind the holes on mounting strip 1 as soon as the connecting strip 30 reached position 1 on mounting strip correspondent. As an alternative to a union separable by both sides, it also fits perfectly the possibility of an embodiment that only present on one side the union described above by elastic tabs, while on the other side of the connection strip 30 a screw connection is provided habitual.

A particularly advantageous variant of this improvement is that the elastic tabs located at each end of the connecting strip 30 are part of a common locking element of the strips, which is located in the central arm of the connecting strip 30, passing the tabs elastic in the upper part of the side walls, laterally through holes. For this the element of locking of the strips is carried out in such a way that the elastic tabs are collected inside the power strip union 30 by the effect of a force exerted from above on the element. Through an additional hole provided in the arm center of mounting strips 1 is easily accessible from above the locking element of the strips, and you can operate for example by means of a screwdriver, so that the union can be released again by a simple maneuver.

The support elements of the threads 10 which in Figure 7 are not represented for reasons of clarity, they are made in the slightly different junction zone in order to take into account the connecting strip 30 additionally arranged in the mounting strip. For example, the support elements of threads 10 do not have support struts in this area 16. To join the conductive current profiles are provided in the arms sides 30a and 30b of the connecting strip 30, two elements of union 31 presenting the recesses 32 mentioned above. Inside of these recesses 32 metal connectors are arranged that join from both sides with the threads that have to be spliced each. The shape of the opening of the recesses 32 is chosen in such a way that they also meet the criteria of security of offering protection against contact. For make the connection with the joining elements 31, the elements of connection 31 of the adjacent support elements of the threads also They have their ends modified.

In the example shown they have arranged to both sides of the connecting strip 30 connecting elements 31 identical, each with six recesses 32. This means that the upper recess 32 of the connecting element 32 located on the side right is free, since the corresponding lateral wing 10a It has only five slots 11 for five-wire support 6. Of course, however, elements of union corresponding to the exact structure of the elements of thread support.

The most detailed form of a joint element 31 is represented in Figure 8. It is composed of a base part shaped like a drawer and open on the underside, where They introduce metal connectors 35 from the inside. recesses 32 of the base part 33 are accessible from both front ends through holes 36 in the form of funnel, where when introducing a thread in a hole in the form of funnel 36, it contacts the metal connector 35. After placing the metal connectors 35 the part is closed base 33 from the underside using a cover plate 34. The establishment of contact by a luminaire module in the area of the connecting element 31 takes place due to the fact that the connection contacts of the contact setting item are compress against the upper face of a setting plate of contact 37 of metal connectors 35. At the ends of the metal connectors 35 this task is assumed again by the threads, so that no gap is produced in which it is not Contact establishment possible.

The most detailed configuration of a connector Metallic 35 is represented in Figures 9a and 9b. It consists of a contact establishment plate 37 elongated and slightly curved down its longitudinal sides, whose mission is to receive the electric current from the wires and broadcast it. At the ends of the plate setting contact 37 an elastic U-shaped element 38 is disposed, represented in detail in Figure 9b, and composed preferably of a chromium-nickel alloy. He elastic element 38 has an elastic tongue 39 bent towards the interior through which a thread inserted into the metal connector 35 being held tightly enough as for the electrical resistance of transition with respect to the contact setting plate 37. This prevents also that when there is a variation in thermal expansion of the current conductor profile the wires can move swelling or deflecting. The setting plate side of contact 37 which is tinned copper, away from the wires, form the contact setting surface for the contacts of the Contact establishment item. To improve contact between the contact setting plate 37 and the wires, the contact setting plate 37 presents on its underside a recess 43 slightly curved or triangular.

Fixing the elastic elements 38 in the ends of the contact setting plate 37 takes place through the recesses 40 located on the side walls of the elastic elements 38, into which the projections 41 of the contact establishment plate 37. The stable arrangement of the metal connectors 35 in the connecting element 31 is seen further reinforced by the fact that on the cover plate 34 are located a plastic spikes 42 that after placing the cover plate 34 pushes from the bottom face against the contact setting plates 37 of the connectors metallic 35. Since the pins 42 also fit into side recesses 43 of the bent longitudinal sides down from the contact setting plates 37, it it also prevents lateral displacement of the metal connectors 35. In addition to this, the pins 42 represent also a barrier that limits the diversion of the threads. The element of union represented here closes the gap between the elements of support of the wires of the current conductor profiles of so that it is possible to assemble busbars 1 already fully equipped with current conductive profiles that You can contact continuously, and you can set the contact also in the areas of union.

The application of this joint element is not limited to the example represented with the support elements of the threads. For example, the joint element shown in the Figures 7 to 9b can also be applied in the light row system initially cited in which current conductive profiles They are manufactured by an extrusion process and are single piece and apply for joining.

As an alternative to the aforementioned employment of a swivel socket adapted for the power supply of the network may also be provided a network connection element that it can be connected on the front side of a conductive bar and that act in conjunction with the metal connectors, by which the wires of the busbar system join with the lines of the network.

Finally it is about explaining by Figures 1 and 10 the detailed structure and operation of the contact establishment element made as a take swivel 50. Figure 10 shows the swivel 50 with a coating profile 5 arranged on its underside, seen in perspective. The essential element of the rotating socket 50 is the contacts 53 and 54 arranged on the outer face of the base body cylindrical 61, which can be adjusted in height to set optionally contact with the various wires 6. Other establishment of grounding contact, which however you cannot choose freely but it comes predetermined, it performed by thread element 62. This thread element 62 goes conducted in a groove 63 provided in the base body 61, being one end 62a of the wire element 62 fixed under pressure by its shape in the cover profile 5 of the luminaire module. He other end 62b protrudes laterally at the height of the thread of grounding. The rotating socket 50 also presents in its part bottom two locking elements 52 protruding sideways.

Establishing contact with threads 6 of the current conductor profile takes place when it is entered the rotating socket 50 connected to a lighting module in the hole bottom of the mounting strip 1. As can be seen in the Figure 1, cylindrical base body 61 has different heights, where the horizontal arm 14 located only on the right side of the mounting strip prevents the setting element of contact 50 can be inserted in mounting strip 1 in inverted position.

After inserting the rotating socket 50, it is rotated this approximately 45 °, whereby the blocking elements 52 arranged laterally fit into parts of the mounting strip 1 or of the current conducting profile that protrude towards the interior, thus performing the mechanical fixation of the module the luminaire At the same time the connection contacts 53 are rotated and 54 inside the slots 11 of the support elements of the wires 10, so that the electrical contact is established wanted. As already mentioned above, some or all contacts can have height adjustment, which in the represented example is performed because the support element 55 of the contact 53 can be moved vertically on the guide rails 56 and 57. Both the support element 55 and the base body cylindrical 61 are made with guide rails 56 and 57 of such so that the support element 55 can easily fit into the positions corresponding to threads 6, which is facilitated the exact positioning of the contact 53.

Slot 63 forms for thread element 62 an eccentric stop, causing the end 62b of the thread element 62 is compressed during rotation of the rotating socket 50 on the lower left thread 6 provided for the land. This establishes an earth connection between the profile of metallic coating 5, which is part of the module of the luminaire, and metal mounting strip 1. To do this it is it is necessary that the thread element 62 has a certain mechanical resistance, so it is preferably made of a galvanized steel wire or a CrNi wire.

The coating profile 5 arranged in the bottom face of the rotating socket, close the mounting strip 1 down, which at the same time prevents the penetration of powder. In the area of the contact setting element 50, the covering profile 5 has an elongated groove in which the rotating lever 58 can be inserted upwards in the locked position, so that below is flush with the coating profile 5. This way a closing is achieved complete of mounting strip 1.

The coating profile 5 is also used in those places where modules are not arranged luminaires In the case of fixing a luminaire module, the profile of coating 5 also constitutes the support for all the elements of the luminaire module, being arranged for example the reactances at the top on the profile of coating 5, thus penetrating into the interior space of the U-shaped mounting strip. The rotating socket 50 that is has described allows you to easily establish contact with the threads, as well as perform a mechanical fixation of the module of the luminaire in the busbar system. The application of rotating socket 50 shown is especially advantageous in the solution presented in which the free establishment of contact along the entire length of the bar system conductive, since it can be used especially flexible and can be removed again.

The present invention therefore describes a high performance busbar system, which for the first once offers the possibility of a contact establishment and arrangement of the luminaire modules totally free. The consequence of this is that the different modules of luminaires do not have to adapt to lengths anymore determined to allow an adequate disposition within the busbar system. The application is not limited to represented example of U-shaped conductive bars. thread support elements can be applied for example also on conductive bars with different profiles, for example A profiles or Y profiles. This is equally applicable to union element described. They can also be significantly reduced manufacturing costs, since the support elements of the threads can be manufactured in a considerably simpler way and faster than in known current conductor profiles. In addition to this, the present invention offers a possibility of circumvent the problems that arise with respect to differences in temperature that give rise to a variation in length and a displacement of plastic parts.
