[0001] Electrical module for connection to a mounting rail and contacting element for this

[0002] Description:

[0003] The present invention relates to an electrical module according to the preamble of claim 1, which is intended to be coupled to a mounting rail, wherein the mounting rail has a mounting rail profile with two side walls and at least one busbar arranged in the mounting rail profile with contactable lines. The module according to the invention can be, for example, a light, a camera, or a sensor unit, or generally a unit intended for use in a strip lighting system. Furthermore, the present invention relates to a corresponding contacting element for such an electrical module.

[0004] Support rails with a support rail profile and a busbar held in the support rail profile are known from the prior art and are used, for example, to create elongated so-called continuous lighting systems. One known continuous lighting system is marketed by the applicant under the name "TECTON" and is characterized by the fact that luminaires or other electrical loads can be flexibly positioned on the support rail along the entire length of the system. This is made possible by the fact that, thanks to a special mounting of the busbar cables, they are accessible to the loads along essentially the entire length of the continuous lighting system, so that contact with the cables can be made not only at fixed positions, but at any location. WO 2001 / 091250 Ai, for example, shows such a continuous lighting system.

[0005] In the "TECTON" system mentioned above, two busbars are arranged opposite each other on the inside of the two side walls of a downwardly open, U-shaped support rail profile. The contact between the busbar cables is achieved by the luminaire or load having a rotatable contact element, which is inserted into the support rail from below and then rotated by approximately 45°. 0is twisted. The contacts arranged on the contacting element are designed in such a way that they are pivoted out sideways when twisted and ultimately contact the conductors of the busbars when twisted. In addition to the electrical contacts, locking projections are also pivoted out sideways, which also mechanically fasten the contacting element to the support rail. A carrier element is also coupled to the contacting element, to which, for example, in the case of a light fixture, the lamps and, if applicable, other electronic components for operating the lamps are attached.

[0006] These rotating contact elements, often referred to as rotary taps, are typically arranged on both sides of the load to be connected to the mounting rail for stability reasons in the mounting rail systems described above. This applies particularly to elongated luminaires, but also to shorter units such as spotlights, sensors, and the like. Typically, only one of the two rotary taps serves both for mechanical fastening and electrical contact with the busbar cables; the second rotary tap at the opposite end is used solely for stability reasons and provides mechanical locking to the mounting rail.

[0007] However, this approach limits the possibilities for free arrangement on the mounting rail, particularly with shorter units such as spotlights or sensors. The reason for this is that at the front end and at the opposite end of the mounting rail, the contactable cables of the busbars do not extend to the very end, as measures must be taken here for the feed-in and for the termination of the mounting rail or, if necessary, for the connection to another mounting rail. If two such rotary taps are used for a relatively short load to be connected, they are inevitably located at the beginning and end of the load, which in turn means that the load can only be arranged at a certain minimum distance from the beginning or end of the mounting rail system.

[0008] A similar problem arises when only a single rotary tap is used. In this case, it is again located off-center and thus closer to the end of the associated load, since the electrical components to be supplied with power are usually located centrally, and the required cable routing then requires the rotary tap to be offset from the electrical components. This also results in uneven load distribution, which is also detrimental to the mounting of the load to the mounting rail.

[0009] The present invention is based on the object of offering an improvement that makes it possible to further minimize the above-described restrictions on the positioning of electrical modules on a support rail.

[0010] The object is achieved by an electrical module having the features of claim i, as well as by a contacting element for an electrical module according to claim 10. Advantageous developments of the invention are the subject of the dependent claims.

[0011] According to the present invention, the contacting element is modified in such a way that a channel for passing through cables or wires is available in the rotational axis around which the contacting element can be rotated. In the case of an electrical module, it is then provided that, starting from one of the connection contacts, at least one cable is guided through this channel and a correspondingly aligned through-opening in the carrier element of the electrical module to the side of the carrier element opposite the contacting element, in order to supply an electronic component of the module. This opens up the possibility, for example,For relatively short electrical modules, only a single contacting element can be used, which can now be positioned centrally. Due to the advantageous cable routing, the electronic component to be supplied, such as the spot or sensor, is then positioned directly beneath the contacting element. This not only results in a central power flow, which enables the use of a single contacting element, but also, due to the fact that the contacting element is no longer located at the end or edge of the electrical module, but instead is located centrally, has the advantage that the electrical module can now be arranged right up to the outermost edge of the mounting rail, despite any measures for feeding the busbars or for terminating the mounting rail system.

[0012] According to the present invention, an electrical module for connection to a mounting rail, which has a mounting rail profile with two side walls and at least one busbar, which is arranged on one of the two inner sides of the side walls of the mounting rail profile and provides electrically contactable lines, is proposed,

[0013] • wherein the electrical module comprises a contacting element which can be inserted into the mounting rail profile and has connecting contacts which are intended to come into contact with lines of the busbar when the contacting element is inserted into the mounting rail profile,

[0014] • wherein the contacting element is mounted so as to be rotatable about a rotation axis relative to a carrier element of the electrical module between an open position, in which insertion and removal of the contacting element from the support rail profile is possible, and a contacting position, in which the connection contacts contact lines of the busbar, and

[0015] • wherein the contacting element has a cable guide channel running substantially along the axis of rotation, which is aligned with a through-opening in the carrier element, and at least one cable is guided from one of the connection contacts through the cable guide channel and the through-opening to the side of the carrier element opposite the contacting element in order to supply an electronic component of the module.

[0016] Furthermore, a contacting element for an electrical module for connection to a mounting rail, which has a mounting rail profile with two side walls and at least one busbar, which is arranged on one of the two inner sides of the side walls of the mounting rail profile and provides electrically contactable lines, is proposed,

[0017] • wherein the contacting element can be inserted into the mounting rail profile and has connecting contacts which are intended to come into contact with lines of the busbar when the contacting element is inserted into the mounting rail profile,

[0018] • wherein the contacting element is mounted so as to be rotatable about an axis of rotation relative to a carrier element of the electrical module between an open position, in which insertion and removal of the contacting element from the support rail profile is possible, and a contacting position, in which the connection contacts contact lines of the busbar, and • wherein the contacting element has a cable guide channel running substantially along the axis of rotation and at least one cable is guided through the cable guide channel starting from one of the connection contacts in order to supply an electronic component of the module.

[0019] Preferably, the contacting element comprises a base body rotatably received in the support element of the electrical module, as well as a contact holding body that holds the connection contacts and is arranged on the base body and rotates with it. Both the base body and the contact holding body have openings that together form the central cable routing channel. This enables the realization of a particularly advantageous development of the solution according to the invention, in which the contacting element is designed in such a way that it is prevented from being rotated too early during insertion into the support rail, which prevents individual contacts of the contacting element from inadvertently contacting the wrong lines of the busbars.In this particularly advantageous development, the contact holder body of the contacting element is mounted adjustably relative to the base body along the rotational axis of the contacting element, specifically between a) a locking position in which rotation of the contacting element is blocked, and b) a release position in which rotation of the contacting element is possible, wherein the contact holder body is preferably elastically prestressed into the locking position and particularly preferably the contacting element has a spring, in particular a spiral spring, which is effective between the base body and the contact holder body.

[0020] The contact holder body preferably has contact surfaces designed to interact with the mounting rail profile such that the contact holder body is moved toward the release position upon insertion of the contacting element into the mounting rail profile. Preferably, the release position is only reached when the electrical module is fully seated against the mounting rail. During the connection of the electrical module to the mounting rail, the contact holder body is moved from the locked position toward the release position by corresponding interaction with the mounting rail profile, counter to the preferably present spring force. This position is only reached when the module is in the appropriate position.

[0021] In this case, it can preferably also be provided that the contact holder body has blocking elements which, in the locked position of the contact holder body, interact with the carrier element in such a way that rotation of the contacting element is blocked. In the release position of the contact holder body, however, these blocking elements then engage in recesses or undercuts in the carrier element in such a way that rotation of the contacting element is now possible.

[0022] Preferably, it can further be provided that the contacting element has an additional mechanical locking part, which is arranged as a separate component on the base body and rotates with the base body. This locking part is then designed such that, in the contacting position of the contacting element, it effects a mechanical locking between the mounting rail profile and the carrier element, wherein the additional locking part is preferably arranged as an insert between the base body and the contact holder body. In comparison to the base part and the contact holder body, which are generally made of plastic, the additional locking part can be made of a different, in particular a more stable, material. For example, the additional locking part can be designed as a sheet metal part or a metal part.This locking part significantly increases the force absorption, so that even a single contacting element is sufficient to securely lock an electrical module with a relatively high weight to the mounting rail.

[0023] Locking with the aid of the additional locking part is preferably achieved in that it has two outward-facing arms, which, in the contacting position of the contacting element, effect the mechanical locking between the support rails and the support element. In particular, it can be provided that end regions of the two arms each engage behind both the support rail and the support element, with the end regions particularly preferably being C-shaped and engaging behind the support rail from above on one side and the support element from below on the other. This enables particularly stable fastening of even very heavy electrical modules or luminaires to a support rail.

[0024] Overall, the inventive design of the contacting element means that it now also serves as the sole fastening component for reliably mounting electrical modules on a mounting rail. Due to the resulting advantageous positioning of the contacting element on the electrical module, the flexibility regarding the arrangement of such a module on a mounting rail is further increased.

[0025] The invention will be explained in more detail below with reference to the accompanying drawings. They show:

[0026] Figure 1 shows an exploded view of an electrical module according to the invention with a corresponding contacting element;

[0027] Figure 2 shows a partial section through the contacting element;

[0028] Figure 3 shows the arrangement of the contacting element within a schematically indicated mounting rail;

[0029] Figures 4 - 7 show various possibilities for arranging electronic components on the underside of the electrical module opposite the contacting element according to the invention and

[0030] Figures 8 and 9 show views of an electrical module with a contacting element according to the prior art.

[0031] As already mentioned, the present invention represents, for example, a further development of the known “TECTON” system. Before the solution according to the invention is described in more detail, the basic design of such a support rail system will therefore first be explained below with reference to Figures 8 and 9.

[0032] Figure 8 shows a view of the mounting rail in which the busbars are arranged, which are contacted by an electrical module—here, a luminaire. Figure 9, in turn, shows the design of a luminaire to be connected to this mounting rail system with a contacting element provided for this purpose.

[0033] It can be seen here first of all that the known support rail system 100 uses an elongated support profile rail 101 with a U-shaped cross-section and open downwards, which, with its two side walls 102 and 103 as well as the upper connecting wall 104, delimits an elongated receiving space that is accessible from the underside via an elongated coupling opening. In the case shown, a so-called busbar 120 or 130 is arranged on the inner sides of both side walls 102, 103, each of which has a plurality of wires or conductors 121, 131 running in the longitudinal direction, which are arranged in elongated channels or grooves of a cable receiving structure 125, 135 made of an insulating material. The channels ensure secure storage of the conductors 121, 131 such that they cannot be accidentally touched.At the same time, however, the channels are each designed to be open towards the interior of the support profile rail 101, so that contacting of the conductors 121, 131 is possible.

[0034] A luminaire 140 to be connected to this support rail system 100 then has at least one rotatably mounted contacting or tapping element 145, as can be seen in particular in Figure 9, which is arranged on an elongated support element 142 of the luminaire 140. To connect the luminaire 140, it is attached from the underside to the elongated support profile rail 101, wherein the contacting element 145 is inserted into the support profile rail 101 via the elongated coupling opening and then rotated by approximately 45 0is rotated. Contacts 146 arranged on the contacting element 145 are designed such that they are pivoted laterally by the rotation and then - as can be seen in particular in Figure 8 - engage in the receiving channels of the two busbars 120, 130 in order to contact the corresponding conductors 121, 131.

[0035] In the illustrated case, contacts 146 are arranged on both sides of the contacting element 145 in order to contact the busbars 120, 130 positioned on both side walls 102, 103 of the support profile rail 101. Because the contacts 146 can be moved vertically with an associated contact holder part relative to a contact holder body 148 of the tapping element 145, they can be arranged according to the position of a desired conductor 121, 131 in order to then contact this corresponding conductor as desired. This provides the option of selecting the phase and the neutral conductor for the power supply. Depending on the number of conductors provided by the busbars 120, 130, these can also be used for other purposes, such as communication.This makes it possible to combine the luminaire units connected to the support profile rail 101 into a larger light strip system and to control the luminaires centrally from a central control unit.

[0036] Rotating the contacting element 145 to pivot out the contacts 146 also causes locking or latching projections 149 arranged on the contact holder body 148 to pivot outward. These latching projections 149 are also designed such that they do not initially hinder insertion of the contacting element 145 into the support profile rail 101. However, if the contacting element 145 is then in the rotated contacting position, these latching projections 149 also protrude outward and, in particular, overlap inward-facing lower profile regions 105 of the support profile rail 101, thereby providing a mechanical fastening of the luminaire 140.

[0037] In addition to the luminaire unit shown in Figures 8 and 9, other electrical units can also be connected to the trunking system. Sensors such as presence or brightness sensors, which support automated operation of the lighting system, are particularly suitable. Units that enable communication or data transmission for other purposes independent of the lighting control system would also be conceivable as useful units to be connected to the trunking system. Finally, a wide variety of luminaire types—such as spotlights, suspended luminaires, and the like—are also conceivable. These can be connected together to the trunking rail and thus fulfill different lighting technology tasks.

[0038] In addition to the contacting element 145 shown in Figure 9, loads to be connected to a mounting rail system generally also have a second, identically constructed contacting element, which, however, serves only to mechanically lock the load to the mounting rail. This second contacting element therefore does not have any connection contacts that contact the conductors of the busbars after the contacting element is rotated. Instead, the aforementioned locking projections are simply pivoted outward to overlap corresponding profile areas of the mounting rail. To achieve even load distribution, the two contacting elements are arranged, if possible, on opposite sides of the electrical module to be connected.

[0039] If the electrical module to be connected is an elongated luminaire, the two contact elements can still be arranged at a certain distance from the ends on the luminaire's support element. This distance can be dimensioned in such a way that it bridges the necessary infeed and outfeed measures at the beginning and end of a mounting rail system, thus making it possible to arrange luminaires so that they extend to the very end of the mounting rail.

[0040] However, if the units to be connected are shorter, as may be the case with spotlights, sensors, or similar components, the contacting elements must be positioned closer to the edge, which limits the options for arranging such a load at the beginning or end of a mounting rail. At the same time, the use of two rotary taps leads to increased material costs.

[0041] With the inventive solution described below, these problems can be avoided, so that the possibilities for variable design of a light strip system are further increased.

[0042] Figures 1-3 show an electrical module 1 designed according to the invention, which is characterized in particular by the special design of the contacting element. The other components of the electrical module 1 are not shown here for reasons of clarity.

[0043] The support element 30 of the electrical module 1 according to the invention is again designed in the form of a profile part, which is attached to the support rail profile and locked to it. Typically, the support element 30 is a correspondingly formed, elongated sheet metal part, which then supports the other components of the module 1. It is also known from the prior art to use a circuit board used for mounting LEDs directly as a support element and then deform it accordingly. This would of course also be conceivable within the scope of the present invention for the realization of shorter luminaires.

[0044] According to the illustrations, the support element 30 has a horizontal transverse web 31, which is delimited on both longitudinal sides by corresponding lateral regions 32 and 33. These, together with the transverse web 31, form a receiving region 5 extending in the longitudinal direction L, which serves in particular to receive at least the lower part of the contacting element 10. In particular, this contacting element 10 is received in the receiving region 5 in such a way that it can be rotated relative to a vertically extending axis I, specifically between an open position on the one hand and a contacting position on the other.

[0045] In the illustrated embodiment, the rotation of the contacting element 10 can only occur when it is fully inserted into the support rail 60—which is schematically indicated in Figure 3. This is made possible by the fact that the contacting element 10 is formed from essentially two components: a base body 15 on the one hand and a contact holder body 20 on the other. Both components 15, 20 are coupled to one another in such a way that they can only be rotated together relative to the axis I. They therefore have a fixed relationship to one another with respect to this axis I.

[0046] Furthermore, a relative displacement can occur between the base body 15 and the contact holder body 20 along the rotation axis I, as shown by the double arrow, wherein, with the aid of a spiral spring 19 supported on both elements, the contact holder body 20 is initially pressed, in the unloaded state, into a position remote from the base body 15, which represents a so-called locking position. In this locking position, blocking elements 25 and 26 provided in the lower region of the contact holder body 20 are located at the level of inwardly projecting projections 32a, 33a of the side wall regions 32 and 33, respectively, of the carrier element 30, so that pivoting of the contacting element 10 from the open position into the contacting position is not possible.Only when the contact holder body 20 is pressed downward relative to the base body 15 against the spring force 19 does both blocking elements 25 and 26 move further downward, so that they are now located at the level of undercuts 32b, 33b of the side wall regions 32, 33 of the carrier element 30. In this case, rotation of the contacting element 10 about the axis I is then possible, since the blocking elements 25 and 26 can now engage in these undercuts 32b, 33b.

[0047] The contact holder body 20 is pressed down into the release position automatically when the electrical module 1 is attached to a support rail 60, such that the release position is reached the moment the electrical module 1 has been fully attached to the support rail 60. For this purpose, the contact holder body 20 has corresponding contact surfaces which interact with the profile of the support rail 60 in such a way that when the electrical module 1 is attached to the support rail 60, the contact holder body 20 automatically moves against the spring force in the direction of the carrier element 30 until it is in the release position when the module 1 is fully attached to the support rail 60. Only then can the contact holder body 20 be rotated, which causes the previously blocked contacting elements to pivot sideways in order to contact the lines of the busbars.

[0048] At the same time, first locking elements 22 are also provided on the contact holder body 20, which in turn overlap corresponding parts of the mounting rail profile in such a way that, in addition to the electrical contacting, a (first) mechanical locking of the electrical module 1 on the mounting rail 60 is achieved.

[0049] In addition, the mechanical fastening is further improved by the use of an additional, separate locking part 40, which is arranged as an insert between the base body 15 and the contact holder body 22. This locking part 40 is preferably a metal part, for example, a sheet metal or die-cast aluminum part, although other materials are also conceivable. In particular, however, the locking part 40 should be made of a more stable material than the contact holder body 20.

[0050] The locking part 40 is mounted in such a way that it rotates together with the base body 15 and the contact holder body 20. The C-shaped end regions 45 of the locking part 40, in the contacting position of the contacting element 10, engage over projections of the support rail profile, analogous to the locking elements 22 of the contact holder body 20, and simultaneously engage under projections of the support element 30. The assembled combination consisting of support rail profile and support element 30 is thus engaged from both the top and the bottom, which ultimately results in an extremely stable attachment of the electrical module 1 to the support rail 60, even in the case of modules that have a higher weight.

[0051] In principle, the use of a single contacting element 10 for the reliable mounting of electrical modules 1 on mounting rail profiles would be conceivable, although this would then pose the problem that the electrical components of the module must be connected in a suitable manner to the connection contacts of the contacting element 10.

[0052] For this purpose, the invention provides that - as shown in Figure 2 - a channel 50 extending along the axis of rotation I is formed within the contacting element 20 and is aligned with a circular opening 35 in the carrier element 30. The channel 50 is formed by corresponding openings in the contact holder body 20 and the base body 15. The circumferential web 36 provided at the opening 35 in the carrier element 30 also serves to center the contacting element 10, as can be seen in Figure 2, since a correspondingly circular flange region 16 of the base body 15 engages in the opening formed by the web 36.

[0053] What is crucial, however, is that the channel 50 and the opening 35 of the carrier element 30 aligned therewith create a passage to the underside of the carrier element 30 opposite in the contacting element 10, through which a power supply or other electrical connection of a consumer located at this position can be established.

[0054] As can be seen in Figure 3, it is therefore provided that, starting from the connection contacts 24, corresponding cables or lines 55 are introduced into the channel 50 from the top side and then extend through the channel 50 and the through-opening 35 in the support element 30 to the bottom side, so that the arrangement and power supply of a consumer can take place directly here.

[0055] This design makes it possible to position both the contacting element 10 and the load to be supplied centrally on the support element 30 with respect to the longitudinal direction. This was not possible until now, since the cable connecting the connection contacts 24 to the load was routed through the support element 30 via an opening offset laterally to the contacting element 10 in the longitudinal direction. This solution required at least one of the two components - contacting element 10 or unit to be supplied - to be positioned off-center. Ultimately, this led to previous solutions in which the unit to be supplied was arranged centrally on the underside of the support element 30, but then off-center, and corresponding contacting elements 10 were positioned on either side.

[0056] However, as already mentioned, the present invention now creates the possibility of positioning both components centrally on the support element 30 while still achieving a suitable electrical connection. This applies to a wide variety of loads arranged on the underside of the support element 30, with Figures 4-7 showing various examples.

[0057] Figure 4, for example, shows, as a first exemplary embodiment, an electrical module 1 which includes a sensor 70 on the underside of the carrier element 30. This sensor 70 can, for example, be a brightness and / or presence sensor. It is housed in a cylindrical housing 72, which, however, is significantly shorter than the longitudinal extent of the carrier element 30. A central arrangement of the sensor 70, viewed in the longitudinal direction, is advantageous here for aesthetic reasons. However, due to the possibility of also arranging the contacting element (not shown) centrally, the use of a single contacting element for the electrical coupling to the busbar(s) and for the mechanical fastening to the mounting rail is now sufficient.

[0058] Figure 5 shows the possibility of arranging a box 75 centrally below the – partially indicated – contacting element 10, into which the electrical connection of a load is then made. This variant is suitable, for example, for lights that are then suspended from the box 75 via a cable. Again, the length of the support element 30 can be relatively short, although the central arrangement of both the box 75 and the contacting element 10 enables balanced force transmission.

[0059] In a similar manner, the connection of a radiator or a sensor can also be achieved using a tube 80 extending downward from the underside of the support element 30, as shown in Figure 6. The actual consumer 82 is then positioned on the underside of the tube 80 and thus spaced from the support element 30.

[0060] Finally, Figure 7 shows the basic possibility of positioning a universally usable adapter 85 below the through-opening 35 of the support element 30, which adapter then serves to hold, for example, different spotlights or the like.

[0061] In all of the variants presented, the electrical module can now be attached to the mounting rail, as well as electrical contacting and power supply, using a single contacting element 10. One consequence of this is that—as indicated in Figure 1—the support element 30 projects a certain distance d on both sides of the contacting element 10 in the longitudinal direction L. This distance is ideally dimensioned to bridge corresponding coupling and decoupling measures at the end region of the mounting rail, so that even modules with a relatively short length can now be positioned right up to the outermost end of a mounting rail.

[0062] Finally, it should be noted that the measures described above with regard to securing against premature, unintentional twisting of the contacting element, as well as the use of the additional locking element, represent particularly advantageous developments of the invention. In principle, however, it would also be conceivable to dispense with these measures and thus simplify the design of the contacting element, provided that it continues to have the channel according to the invention, which enables the particularly advantageous cable routing and thus the connection of the electrical load.
