Description

[0001] manual:

[0002] The invention relates to an electrical module according to the preamble of claim 1, which is to be connected to a support rail, wherein the support rail has a support rail profile with two side walls and at least one busbar with conductive conductors arranged in the support rail profile. The module according to the invention can be, for example, a lighting device, a camera or a sensor unit, or a universal unit designed for a light strip system. The invention also relates to a conductive element for use with such an electrical module.

[0003] Support rails with support rail profiles and busbars held therein are known from the prior art and are used, for example, to realize elongated so-called light strip systems. A known light strip system is marketed by the applicant under the name "TECTON" and is characterized in that lighting devices or other electrical consumers can be flexibly positioned at the support rail along the entire length of the system. This is made possible by the fact that, due to the special arrangement of the conductors of the busbar, these conductors are accessible to the electrical consumers along substantially the entire length of the light strip system, so that the conductors can be switched on not only at fixed predetermined positions, but also at any point. For example, a light strip system of this type is shown in WO 2001 / 091250 A1.

[0004] In the "TECTON" system mentioned above, two busbars are arranged opposite each other on the inner sides of the two side walls of a U-shaped support rail profile that is open downward. The conduction of the busbar conductor is carried out in that the lighting device or electrical appliance has a rotatable conduction element, which is introduced into the support profile from the bottom and then rotated about 45°. The contacts arranged at the conduction element are implemented in this way so that these contacts are turned out laterally by rotation and finally the conductors of the busbar are conducted in the rotated state. In addition to the electrical contacts, the snap-in protrusions are also turned out laterally, with the help of which the conduction element can also be mechanically fixed to the support rail. In addition, the carrier element is also connected to the conduction element. For example, in the case of a lighting device, the light-emitting body and other electronic components that may be used to operate the light-emitting body are connected to the carrier element.

[0005] These rotatable conducting elements are also often called rotary taps. In order to ensure the stability of the above-mentioned support rail system, they are usually arranged at the ends of both sides of the electrical appliances that need to be connected to the support rail. This is especially applicable to long strip lighting equipment, but also to shorter units such as spotlights, sensors, etc. In this case, usually only one of the two rotary taps is used for both mechanical fixation and electrical conduction of the busbar conductor, and the second rotary tap on the other end is only used for stability reasons and to ensure mechanical locking with the support rail.

[0006] However, such a design results in a limited freedom of arrangement on the support rail, especially for shorter units such as spotlights or sensors. The reason for this is that at the front end of the support rail and at the opposite end, the busbar-conducting conductors do not extend to the outermost end, since measures must be taken here to ensure that the feed-in and the end of the support rail are closed or, if necessary, connected to another support rail. If two such rotary taps are used to connect a relatively short load, they have to be located at the beginning and end of the load, which in turn means that the load must be arranged at a certain minimum distance from the beginning or end of the support rail system.

[0007] Similar problems also arise if only one rotary tap is used. In this case, the rotary tap is again offset from the center and is therefore located more in the terminal area of ​​the associated load, since the electrical components to be powered are usually arranged in the center and the rotary tap must be arranged offset to the electrical components due to wiring requirements. This also leads to an uneven load distribution, which is also disadvantageous for the fixing of the load on the support rail.

[0008] The object of the present invention is now to provide a development in this respect, which allows the above-mentioned restrictions to be further minimized when positioning the electrical module on the support rail.

[0009] This object is achieved by an electrical module having the features of claim 1 and by a contact-forming element for an electrical module according to claim 10. Advantageous developments of the invention are the subject matter of the dependent claims.

[0010] According to the design of the invention, the conducting element is adjusted so that a channel for the passage of cables or wires is provided in the rotation axis about which the conducting element rotates. For the electrical module, it is then designed that, starting from one of the connection contacts, at least one cable passes through the channel and the correspondingly aligned through-opening in the carrier element of the electrical module to the side of the carrier element opposite to the conducting element, in order to supply power to the electronic components of the module there. In this way, for example, for relatively short electrical modules, only a single conducting element can be used, which can now be positioned centrally, wherein, due to the advantageous wiring, the electronic components that need to be powered, i.e., for example, spotlights or sensors, can also be positioned directly below the conducting element. This then not only leads to a concentrated power flow, making it possible to use a single conducting element, but also has the advantage that, since the conducting element is no longer positioned at the end or edge region of the electrical module, but is located in the center, the electrical module can still be arranged on the outermost edge of the support rail, although possible measures need to be taken to feed in busbars or to close the end of the support rail system.

[0011] Thus, according to the present invention, an electrical module connected to a support rail is proposed, the support rail having a support 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 support rail profile and provides an electrically conductive conductor,

[0012] ● wherein the electrical module has a conducting element which can be inserted into the support rail profile and has connection contacts which are designed to contact the conductors of the busbar when the conducting element is inserted into the support rail profile,

[0013] The conducting element is rotatably mounted relative to the carrier element of the electrical module about a rotation axis between a disconnected position, in which the conducting element can be inserted into or removed from the support rail profile, and a conducting position, in which the contact contacts are connected to the busbar conductor, and

[0014] ●Wherein, the conducting element has a cable guide channel extending essentially along the rotation axis, which is aligned with the through opening in the carrier element, and at least one cable is led from one of the connection contacts through the cable guide channel and the through opening to the side of the carrier element opposite to the conducting element in order to supply power to the electronic components of the module.

[0015] In addition, a conductive element for an electrical module connected to a support rail is proposed, the support rail having a support 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 support rail profile and provides an electrically conductive wire.

[0016] ● wherein the conducting element can be inserted into the support rail profile and has connection contacts, which are designed to contact the conductor of the busbar when the conducting element is inserted into the support rail profile,

[0017] The conducting element is rotatably mounted relative to the carrier element of the electrical module about a rotation axis between a disconnected position, in which the conducting element can be inserted into or removed from the support rail profile, and a conducting position, in which the contact contacts are connected to the busbar conductor, and

[0018] The conductor-conducting element has a cable guide channel which extends substantially along the axis of rotation, and at least one cable is passed through the cable guide channel starting from one of the connection contacts in order to supply the electronic components of the module with power.

[0019] The conducting element preferably has a base body which is rotatably mounted in the electrical module carrier element, and a contact holder for fixing the connecting contacts, which is arranged on the base body and rotates with it, wherein both the base body and the contact holder have openings which together form a central cable guide channel. This enables a particularly advantageous refinement of the solution according to the invention, wherein the conducting element is designed to avoid premature twisting thereof when inserted into the support rail, thereby preventing individual contacts of the conducting element from accidentally contacting the wrong busbar conductor. In this particularly advantageous refinement, the contact holder of the conducting element is mounted so that it can be adjusted along the axis of rotation of the conducting element relative to the base body, i.e. between the following two positions:

[0020] a) a locked position in which the conducting element is blocked from rotating, and

[0021] b) Between the release positions in which the conducting element can rotate,

[0022] In this case, the contact holder is preferably elastically prestressed in the locked position, and the conduction element particularly preferably has a spring, in particular a helical spring, which acts between the base body and the contact holder.

[0023] Here, the contact holder preferably has a contact surface which is designed to interact with the support rail profile so that when the conducting element is inserted into the support rail profile, the contact holder is moved towards a release position, wherein the release position is preferably reached only when the electrical module is in full contact with the support rail. That is, during the connection of the electrical module to the support rail, the contact holder is moved in the direction of the release position by corresponding interaction with the support rail profile, overcoming the existing spring force, wherein in particular it is moved into the release position only when the module is in a suitable position.

[0024] Preferably, in this case, the contact holder can additionally be designed with locking elements, which in the locked position of the contact holder interact with the carrier element and thus block the rotation of the conducting element. In the release position of the contact holder, these locking elements engage in the recesses or undercuts of the carrier element, so that the conducting element can now be rotated.

[0025] In addition, the conducting element can preferably be designed with an additional mechanical locking element, which is arranged as a separate component on the base body and rotates therewith. The locking element is then designed so that in the conducting position of the conducting element, it produces a mechanical locking effect between the support rail profile and the carrier element, wherein the additional locking element is preferably arranged as an insert between the base body and the contact holder. Compared to the base body and the contact holder, which are usually made of plastic, the additional locking element can be made of other materials, in particular more stable materials. For example, the additional locking element can be designed as a sheet metal part or a metal part. The force-bearing capacity can be significantly increased by means of this locking element, so that only one conducting element is sufficient to reliably lock the relatively heavy electrical module on the support rail.

[0026] A preferred way to achieve locking by means of an additional locking element is that the locking element has two outwardly facing arms, which in the conducting position of the conducting element can produce a mechanical locking effect between the support rail and the carrier element. In particular, the end regions of the two arms can be designed to engage with the rear of the support rail and the carrier element, respectively, wherein the end regions are particularly preferably designed to be C-shaped and engage with the rear of the support rail from the top on the one hand and with the rear of the carrier element from the bottom on the other hand. In this way, even very heavy electrical modules or lighting devices can be fixed on the support rail in a particularly stable manner.

[0027] In summary, the design of the conductive element according to the invention makes it the only fixture that can securely fix the electrical module on the support rail. Due to the advantageous positioning of the conductive element on the electrical module, the flexibility of arranging such modules on the support rail is further improved.

[0028] The present invention will be further explained below with reference to the accompanying drawings, wherein:

[0029] Figure 1 An electrical module according to the invention with corresponding conductive elements is shown in an exploded view;

[0030] Figure 2 A partial cross-sectional view of a conducting element is shown;

[0031] Figure 3 shows the arrangement of the conducting element within a schematically shown support rail;

[0032] Figures 4 to 7 shows various options for arranging electronic components on the bottom side of the electrical module relative to the conductive element according to the invention, and

[0033] Figure 8 and Fig. 9 An electrical module with a conductive element according to the prior art is shown.

[0034] As already explained, the present invention represents, for example, an improvement of the known "TECTON" system. Therefore, before describing the solution according to the present invention in more detail, reference will first be made to Figure 8 and Fig. 9 Explain the basic design of this type of support rail system.

[0035] Figure 8 Here, a view of a support rail is shown, in which busbars are arranged, which are conducted through electrical modules (here through lighting devices). Fig. 9 A design for connecting a lighting device to the support rail system is shown, the lighting device having a conducting element designed for this purpose.

[0036] First of all, it can be seen here that the known support rail system 100 uses an elongated, U-shaped cross-section and downwardly open support profile rail 101, which uses two side walls 102 and 103 and an upper connecting wall 104 to enclose an elongated receiving space, which can be entered from the bottom via an elongated connecting port. In the illustrated case, the inner side of the two side walls 102, 103 is respectively arranged with a so-called busbar 120 or 130, and the busbar 120 or 130 each has a plurality of wires or conductors 121, 131 extending in the longitudinal direction, which are arranged in elongated channels or grooves of the wire receiving structure 125, 135 made of insulating material. Here, these channels can ensure the safe installation of the conductors 121, 131 so that they will not be accidentally touched. However, at the same time, the channels are designed to be open to the inner space of the support profile rail 101, so that the conductors 121, 131 can be conducted.

[0037] The lighting device 140 to be connected to the support rail system 100 has at least one rotatably mounted conducting element or tapping element 145, in particular Fig. 9 As shown, it is arranged on an elongated carrier element 142 of a lighting device 140. In order to connect the lighting device 140, it is attached to the elongated supporting profile rail 101 from the bottom side, and the conducting element 145 is inserted into the supporting profile rail 101 via the elongated connection opening and then rotated by about 45°. The contacts 146 arranged on the conducting element 145 are designed in this case so that they are turned to one side by rotation and then - in particular as shown in FIG. Figure 8 As shown, the busbars 120 and 130 are engaged with each other in the receiving channels so as to conduct the corresponding conductors 121 and 131 .

[0038] As shown, the contacts 146 are arranged on both sides of the conducting element 145 so that the busbars 120, 130 located on the two side walls 102, 103 of the supporting profile rail 101 can be conducted. Since the contacts 146 and the associated contact holders can be vertically moved relative to the contact holder 148 of the tapping element 145, they can be arranged corresponding to the desired positions of the conductors 121, 131 so that these corresponding conductors can be conducted as desired later. On the one hand, there is the possibility of selecting the phase for the power supply and the neutral conductor. However, depending on the number of conductors provided by the busbars 120, 130, these conductors can also be used for other purposes, such as communication. There is the possibility of combining the lighting device units connected to the supporting profile rail 101 into a larger light strip system and centrally controlling these lighting devices from a central control unit.

[0039] In addition, the operation of rotating the conducting element 145 in order to rotate the contact 146 outward also causes the locking or latching projections 149 arranged on the contact holder 148 to be rotated to one side. These latching projections 149 are also designed not to initially prevent the conducting element 145 from being inserted into the supporting profile rail 101. However, subsequently, if the conducting element 145 is in the twisted conducting position, these latching projections 149 also project outward and engage with the (especially inward) lower profile area 105 of the supporting profile rail 101, thereby achieving mechanical fixation of the lighting device 140.

[0040] Apart from Figure 8 and Fig. 9 In addition to the lighting device units depicted in the figure, other electrical units can also be connected to the support rail system. In particular, sensors that support the automated operation of the lighting system, such as presence sensors or brightness sensors, are conceivable here. Units that make communication or data transmission for other purposes independent of the lighting control possible are also conceivable as units to be connected to the support rail system. Finally, of course, different lighting device types are also conceivable (such as spotlights, suspended lighting devices, etc.), which can be connected together to the support profile rail and thereby fulfill different lighting technology tasks.

[0041] Apart from Fig. 9In addition to the conductive element 145 shown in the figure, the electrical load to be connected to the support rail system usually has a second conductive element of the same specifications, but it only serves to mechanically lock it with the support rail. That is, after the conductive element is twisted, this second conductive element does not have a connection contact for the busbar conductor. Instead, only the aforementioned snap-in projection will be turned outwards to engage with the corresponding profile area of ​​the support profile rail. In order to achieve a uniform load distribution, the two conductive elements are arranged as far as possible on opposite sides of the electrical module to be connected.

[0042] If the electrical module to be connected is a long strip lighting device, even if two conducting elements are arranged, they can still maintain a certain distance from both ends of the lighting device carrier element. This distance can be designed in particular to be able to bridge the necessary feed-in and feed-out measures at the beginning and end of the support rail system, so that the lighting device can be arranged to extend to the outermost end of the support rail.

[0043] However, if shorter units such as spotlights, sensors or the like need to be connected, the conducting elements need to be positioned in the edge region, which means that the possibility of arranging such loads at the beginning or end of the support rail is limited. At the same time, the use of two rotary taps leads to increased material expenditure.

[0044] These problems can be avoided by the solution according to the invention described below, thereby again further increasing the possibilities for flexible design of the light strip system.

[0045] to this end, Figures 1 to 3 An electrical module 1 designed according to the present invention is shown, which is characterized by a special design of the conductive element. For the sake of clarity, other components of the electrical module 1 are not shown here for the time being.

[0046] The carrier element 30 of the electrical module 1 according to the present invention is also designed as a profile, which is placed on the support rail profile and interlocked with it. The carrier element 30 is usually a correspondingly shaped long sheet metal part, which is then responsible for carrying other components of the module 1. It is also known in the prior art that a printed circuit board used to support LEDs can be directly used as a carrier element and then subjected to corresponding shaping processing. Of course, within the framework of the present invention, a shorter lighting device can also be realized.

[0047] As shown in the figure, the carrier element 30 has a horizontal cross bar 31, which is bounded on both sides in the longitudinal direction by corresponding side areas 32 and 33. Together with the cross bar 31, they form a receiving area 5 extending in the longitudinal direction L, which is used in particular to receive at least the lower part of the conductive element 10. In particular, the conductive element 10 is mounted in the receiving area 5 in such a way that it can be rotated relative to the vertical axis I, that is, between a disconnected position on one side and a conductive position on the other side.

[0048] For the embodiment shown, the conducting element 10 can only be rotated when it is fully inserted into the support rail 60. Figure 3 The specific implementation is that the conducting element 10 is mainly formed by two components, one is the base body 15, and the other is the contact fixing body 20, wherein the two components 15, 20 are connected to each other so as to be able to rotate only together relative to the axis I. That is, they have a fixed relationship relative to the axis I.

[0049] In addition, as indicated by the double arrow, a relative displacement can occur between the base body 15 and the contact holder 20 along the rotation axis I, wherein the contact holder 20 is initially pressed to a position away from the base body 15 in the no-load state, i.e., the so-called locking position, by means of the helical spring 19 supported on the two elements. In this locking position, the locking elements 25 and 26 are designed in the lower area of ​​the contact holder 20, which are located at the level of the protrusions 32a, 33a protruding inwardly from the side wall area 32 or 33 of the carrier element 30, so that the conducting element 10 cannot be swung out from the disconnected position to the conducting position.

[0050] Only when the contact holder 20 is pressed onto the base body 15 against the spring force 19, the two locking elements 25 and 26 are moved further downwards, so that they are now located at the level of the undercuts 32b, 33b of the side wall regions 32, 33 of the carrier element 30. In this case, the conductive element 10 can be rotated about the axis I, because the locking elements 25 and 26 can now engage in these undercuts 32b, 33b.

[0051] Here, when the electric module 1 is placed on the support rail 60, the contact holder 20 is automatically pressed down to the release position, so that when the electric module 1 is completely placed on the support rail 60, the release position is reached instantly. For this purpose, the contact holder 20 has a corresponding contact surface, which interacts with the profile of the support rail 60, so that when the electric module 1 is placed on the support rail 60, the contact holder 20 automatically moves toward the carrier element 30 against the spring force until the module 1 is completely placed on the support rail 60 and is in the release position. Only in this way can the contact holder 20 be rotated so that the previously locked conducting element is swung out to the side to conduct the busbar wire.

[0052] At the same time, a first locking element 22 is also designed on the contact fixing body 20, which in turn engages with a corresponding part of the support rail profile, so that in addition to electrical conduction, the electrical module 1 is also mechanically locked on the support rail 60.

[0053] In addition, the mechanical fixing effect is further improved by using another separate locking member 40, which is arranged as an insert between the base body 15 and the contact fixing body 22. The locking member 40 is preferably a metal member, such as a sheet metal member or a die-cast aluminum alloy member, and other materials are also conceivable. However, the locking member 40 should be made of a material that is more stable than the contact fixing body 20.

[0054] Here, the locking element 40 is supported in such a way that it rotates together with the base body 15 and the contact holder 20. Here, when the conducting element 10 is in the conducting position, the C-shaped terminal area 45 of the locking element 40 engages with the protrusion of the support rail profile similar to the locking element 22 of the contact holder 20 and engages with the protrusion of the carrier element 30 from the bottom. In this way, the assembly consisting of the support rail profile and the carrier element 30 is engaged both from the top side and from the bottom side, which ultimately allows the electrical module 1 to be fixed to the support rail 60 in a particularly stable manner, even when the module has a large weight.

[0055] In principle, it is therefore conceivable to use a single conducting element 10 to securely fix the electrical module 1 to the support rail profile, but this entails the problem that the electrical components of the module must be connected to the connecting contacts of the conducting element 10 in a suitable manner.

[0056] For this reason, Figure 2 As shown, the present invention is designed to form a channel 50 extending along the rotation axis I inside the conductive element 20, which is aligned with the circular opening 35 of the carrier element 30. Here, the channel 50 is formed by the corresponding openings in the contact fixing body 20 and the base body 15. Figure 2 As shown, the circumferential web 36 formed on the opening 35 of the carrier element 30 also serves to center the lead-through element 10 , since a corresponding circular flange area 16 of the base body 15 engages in the opening formed by the web 36 .

[0057] The key is to establish a channel connected to the bottom surface of the carrier element 30 opposite to the conductive element 10 through the channel 50 and the opening 35 of the carrier element 30 aligned therewith, through which the electrical appliance located at this position can be powered or other electrical connections can be made with the electrical appliance located at this position.

[0058] According to this, if Figure 3 As shown, the design is such that starting from the connection contact 24, the corresponding cable or wire 55 is passed into the channel 50 from the top side and then extends through the channel 50 and the through opening 35 in the carrier element 30 to the bottom side, so that the electrical appliance can be arranged and powered directly there.

[0059] With this design, both the conducting element 10 and the electrical load to be powered can be positioned centrally on the carrier element 30 in the longitudinal direction. This was not possible in the past because the cable connecting the connection contact 24 to the electrical load had to pass through an opening that was offset to one side of the conducting element 10 in the longitudinal direction in order to pass through the carrier element 30. When this solution is adopted, at least one of the two components - the conducting element 10 or the unit to be powered - needs to be positioned off-center. Ultimately, this results in that in the previous solution, the unit to be powered is arranged in the center of the bottom surface of the carrier element 30, but then the respective conducting elements 10 are positioned off-center and are correspondingly located on both sides.

[0060] However, as mentioned above, the present invention now allows both components to be positioned in the center of the carrier element 30 and still achieve a suitable electrical connection. This is applicable to various different electrical appliances that need to be arranged on the bottom surface of the carrier element 30, wherein: Figures 4 to 7 Various examples are shown for this purpose.

[0061] For example, Figure 4 As a first embodiment, an electrical module 1 is shown, which comprises a sensor 70 located on the bottom side of a carrier element 30. The sensor 70 can be, for example, a brightness and / or presence sensor. It is accommodated in a cylindrical housing 72, which is however significantly shorter than the longitudinal extension of the carrier element 30. For aesthetic reasons, a central arrangement of the sensor 70 in the longitudinal direction is advantageous, while at the same time, since a conductive element (not shown) can also be centrally arranged, only one conductive element is required for the electrical connection to the busbar and the mechanical fixing to the support rail.

[0062] Figure 5 The possibility of arranging a terminal box 75 centrally below the partially shown conducting element 10 is shown, in which the electrical connection of the load can then be made. This variant is suitable, for example, for lighting devices, which can then be suspended by cables starting from the terminal box 75. Likewise, the length of the carrier element 30 can be relatively short, wherein both the central arrangement of the terminal box 75 and the conducting element 10 enable a balanced force transmission.

[0063] Similarly, if Figure 6 As shown, a radiator or a sensor can also be connected by means of a pipe 80 extending downward from the bottom surface of the carrier element 30. Then, the actual electrical consumer 82 is positioned on the bottom surface of the pipe 80 and then keeps a certain distance from the carrier element 30.

[0064] at last, Figure 7 The basic possibility of positioning a universal adapter 85 below the through-opening 35 of the carrier element 30 is shown, which can then be used as a holder for various light sources or the like.

[0065] That is to say, in all the variants shown, the electrical module can now be fixed on the support rail and electrically connected and powered by a single conducting element 10. One result of this is that Figure 1 As shown, the carrier element 30 projects a certain distance d on both sides of the lead-through element 10 when viewed in the longitudinal direction L. Ideally, this distance d can now be designed such that corresponding feed-in and feed-out measures can be bridged in the end region of the support rail, so that even such modules of relatively short length can now be positioned to the outermost end of the support rail.

[0066] Finally, it should be noted that the measures described above to prevent premature and unintentional rotation of the conducting element and the use of additional locking elements are particularly advantageous refinements of the invention. However, in principle, these measures can also be omitted, thereby simplifying the structural design of the conducting element, as long as it still has the channel according to the invention, which enables particularly advantageous wiring and thus enables connection to the electrical load.
