Description

[0001] A current tap arrangement for a functional insert for a busbar system, as well as a busbar system itself, are described. Furthermore, a method for electrically contacting a current tap arrangement with a busbar is described.

[0002] This patent application claims priority over German patent application 10 2017 125 214.2.

[0003] EP 0 486 714 A1 discloses a light strip with a current tap arrangement according to the preamble of claim 1. Another luminaire with a current rail having a mounting rail is disclosed in DE 27 00 973 A1.

[0004] DE 196 04 222 A1 discloses a connection and coupling system, which is intended in particular for luminaires with a mounting rail and a light carrier. At least one of the plug contacts arranged on a plug is adjustable in its position so that it can be selectively inserted into different socket contacts.

[0005] It is desirable to provide a current tap arrangement for a functional insert for a busbar system that enables simple and flexible operation. It is also desirable to provide a functional insert for a busbar system that is flexibly deployable. Furthermore, it is desirable to provide a busbar system that enables flexible operation of a functional insert. Finally, it is desirable to provide a method for electrically contacting a current tap arrangement with a busbar that is easy to perform. The invention provides a current tap arrangement according to claim 1, a busbar system according to claim 11, and a method according to claim 14.

[0006] According to the invention, a current tap arrangement for a functional insert for a busbar system is provided. The current tap arrangement serves to electrically connect the functional insert to electrical conductors of the busbar system. For example, the busbar system has a busbar. The busbar has a mounting rail. A conductor holder with electrical conductors is arranged in the mounting rail. The mounting rail serves, for example, to mechanically hold the functional insert. The current tap arrangement serves to electrically connect the functional insert to the electrical conductors of the conductor holder. The current tap arrangement serves, for example, to transmit electrical energy from the busbar to the functional unit. Alternatively or additionally, the current tap arrangement serves to transmit control signals between the busbar and the functional insert.

[0007] According to the invention, the current tap assembly has a housing. The housing is, for example, a plastic part. The housing can be attached to the functional insert.

[0008] According to the invention, the current tap assembly comprises a housing insert. The housing insert is arranged within the housing. In a first state, the housing insert is fixed to the housing. In a second state, the housing insert is displaceable relative to the housing along a first direction. The housing insert is, for example, a plastic part. The housing insert is particularly dimensioned such that it can be arranged within the housing. The housing insert and the housing are displaceable relative to each other along the first direction when the housing insert is arranged within the housing. In the ready-to-use state, the first direction is, in particular, a transverse direction of the functional insert and / or a transverse direction of the busbar.

[0009] According to the invention, the current tap assembly comprises a first current collector. The first current collector is coupled to the housing insert. In the first state, the first current collector is displaceable relative to the housing insert along the first direction. In the second state, the first current collector is fixed to the housing insert. The first current collector serves, for example, for electrical contacting the electrical conductors in the busbar. In the first state, the first current collector is displaceable relative to the housing insert and thus relative to the housing along the first direction. In the second state, the first current collector is immobile relative to the housing insert. In the second state, the first current collector, together with the housing insert, is displaceable relative to the housing.

[0010] According to the invention, the current tap assembly has a second current collector. The second current collector serves, for example, to electrically contact an electrical conductor of the busbar. The second current collector is fixed to the housing insert. In the first state, the second current collector, together with the housing insert, is fixed to the housing. In the second state, the second current collector, together with the housing insert, is displaceable relative to the housing along the first direction.

[0011] In the first state, the first and second pantographs are movable relative to each other along the first direction. In the second state, the second pantograph is fixed relative to the housing, and the first pantograph is movable relative to the second pantograph. In the second state, the first and second pantographs are moved together relative to the housing. In the second state, the first and second pantographs are coupled together, immovably relative to each other, along the first direction.

[0012] In lighting systems that utilize a track system to which functional units such as luminaires are attached, and in linear lighting systems where multiple luminaires are arranged in series, electrical cables can run along the entire length of the track system. This provides an electrical supply, also known as a power bus, along the entire length of the track system. Power can be drawn from various points along the track system to supply the different functional units.

[0013] Additionally, it is possible to run cables along a busbar system that do not serve as power supplies, but rather form, for example, data transmission lines or control lines for control elements or other cables. These control lines provide control information for control elements that, for instance, regulate the brightness and / or the switching on and off of individual lights or light fixtures. For example, the busbar system contains electrical lines for operating current and also for emergency power supply.

[0014] For example, the busbar system includes conductors for the normal power supply L1, L2, L3, and N. Additionally, two emergency power supplies, L' and N' as well as L" and N", are provided. Furthermore, two data lines, such as DALI 1 and DALI 2, may be included. Specifically, the conductors for phases L1, L2, L3, L', and L" are arranged in a common plane. The conductors for DALI selection, i.e., for DALI 1 and DALI 2, are arranged in another common plane. The two planes are spaced apart along the second direction. This allows for a smaller installation space while maintaining all required clearances.

[0015] Phase selection is possible by moving the first and second current collectors relative to the housing. For example, the first current collector can be moved between the three phases L1, L2, and L3 in the first state. The second current collector, for example, is assigned to a neutral conductor N in the first state. Thus, in the first state, the second current collector remains assigned to the same neutral conductor regardless of which of the live conductors L1, L2, and L3 the first current collector is assigned to.

[0016] If the current tap arrangement is assigned to one of the emergency power supplies, the two current collectors can be moved relative to each other in the second state so that they are assigned either to the two conductors L' and N' or to the two conductors L" and N". This eliminates the need to assign the two current collectors to the emergency power supply separately. Operating errors during assignment can be avoided.

[0017] With a consistent power tap configuration, flexible selection of the live conductors for the normal operating power supply and also of the emergency power supply is possible. No additional wiring is required for this. In particular, the selection of which conductors should connect the two current collectors can be made during installation in the busbar system and does not need to be pre-selected during manufacturing. Furthermore, different power tap configurations do not need to be provided for different luminaire inserts.

[0018] The current tap arrangement can be used in the same configuration for various functional inserts. Furthermore, it is possible to design multiple functional inserts, such as lighting inserts, in the same way and to define different operating modes for the different lighting inserts by moving the current taps within the respective current tap arrangement. No different wiring is required for this.

[0019] According to the invention, a current tap assembly for a functional insert for a busbar system comprises a housing and a housing insert. The housing insert is arranged in the housing and is fixed to the housing in a first state. In a second state, the housing insert is displaceable relative to the housing along a first direction. The current tap assembly comprises a first current collector that is coupled to the housing insert and is displaceable relative to the housing insert along the first direction in the first state and fixed to the housing insert in the second state. The current tap assembly comprises a second current collector that is fixed to the housing insert and, together with the housing insert, is fixed to the housing in the first state and displaceable relative to the housing along the first direction in the second state.

[0020] According to at least one embodiment, the housing has a retaining element. In the first state, the retaining element engages with the housing insert to fix the housing insert immovably relative to the housing. The retaining element is, in particular, spring-loaded to disengage in the second state and allow movement. Specifically, the retaining element is spring-loaded transversely to the first direction. For example, the retaining element is deflected from its rest position transversely to the first direction to allow movement of the housing insert relative to the housing.

[0021] According to at least one embodiment, the current collector has an actuating element to move the retaining element out of engagement with the housing insert. For example, the actuating element deflects the retaining element from its rest position when the first current collector assumes a predetermined position in the housing insert. The force used to move the first current collector relative to the housing insert is used to deflect the retaining element and thus release the housing insert for movement relative to the housing.

[0022] According to at least one embodiment, the housing insert has a contact holder to fix the first current collector immovably relative to the housing insert in the second state. The contact holder is resiliently designed to allow movement between the first and second states. For example, the contact holder is resiliently movable transversely to the first direction. By moving the first current collector, the contact holder can be deflected from its rest position. For example, the contact holder engages behind the first current collector when it is arranged in a predetermined position within the housing insert. By engaging behind the first current collector, the contact holder fixes it relative to the housing insert in at least one direction.

[0023] According to at least one further embodiment, the housing insert has a stop for the first current collector. In the second state, the first current collector is held between the collector bracket and the stop. In particular, in the second state, the collector bracket blocks movement against the first direction, and the stop blocks movement of the first current collector in the first direction relative to the housing insert. The stop is, for example, formed on a side of the housing insert facing the second current collector. The collector bracket is, for example, formed along the first direction between the stop and a side of the housing insert facing away from the second current collector.

[0024] According to at least one embodiment, the current tap arrangement has a second housing insert. The second housing insert is arranged within the housing and is displaceable relative to the housing along the first direction. The current tap arrangement has a third and a fourth current collector. The third and fourth current collectors are each fixed to the second housing insert. The third and fourth current collectors, together with the second housing insert, are displaceable relative to the housing along the first direction. The third and fourth current collectors serve, in particular, to contact one of the conductors of the busbar. For example, the third and fourth current collectors are designed to be connected to a data line.For example, by moving the second housing insert, it is possible to select which control lines, data transmission lines, or other lines the third and fourth current collectors are assigned to. For example, a selection between DALI 1 and DALI 2 is possible.

[0025] According to at least one embodiment, the first, second, third, and fourth current collectors are all identical in construction. Regardless of their application, the current collectors can be designed identically. For example, the current collectors are separate components from their respective housing inserts. The current collectors are coupled to the housing inserts for operational readiness. This allows for flexible application of the current collectors.

[0026] According to at least one embodiment, the current tap arrangement has a housing cover. The housing cover is, for example, displaceable along a second direction relative to the housing. The second direction is, in particular, transverse to the first direction, and especially perpendicular to the first direction. By displacing the housing cover along the second direction, the respective contact tips of the current taps can be selectively exposed or concealed.

[0027] According to the invention, a current tap assembly for a functional insert for a busbar system comprises a housing. The current tap assembly has a housing cover that is arranged on the housing. The housing cover is displaceable relative to the housing along the second direction. In a first state, the housing cover conceals at least two current taps. In a second state, in which the housing cover is displaced in the opposite direction, the at least two current taps protrude beyond the housing cover.

[0028] In a state where the current tap assembly is not connected to the busbar, the housing cover is positioned away from the housing to conceal the contact points of the current collectors. This protects the contact points during transport before installation. As the current tap assembly is inserted into the busbar, the housing cover is moved in a second direction, moving closer to the housing. The housing cover is then shifted relative to the current collectors, causing the contact points of the current collectors to protrude beyond the housing cover. This exposes the contact points, allowing them to make contact with the electrical conductors of the busbar.

[0029] According to at least one embodiment, the housing has a structure to define different operating positions for the current collectors. In particular, the structures correspond to the spacing of the conductors in the busbar. For example, the structure has indentations or protrusions to create different resistances when the collectors are moved. Thus, the operating positions are perceptible by touch.

[0030] According to at least one embodiment, the housing cover has a plurality of recesses. The recesses correspond to the structure in such a way that the contact tips are assigned to one of the recesses when the current collectors are in one of the operating positions. This allows the contact tips to pass through the housing cover via the assigned recess when the housing cover is moved along the second direction. Thus, regardless of the conductor being contacted, one and the same housing cover can be used.

[0031] According to at least one embodiment, the current collectors each have a coupling element for attaching the current collector. The coupling element serves to fix the current collector to one of the housing inserts.

[0032] According to at least one embodiment, the current collectors each have an electrically conductive current-carrying element. The current-carrying element is displaceable relative to the coupling body, particularly along the second direction. Specifically, the current-carrying element is displaceable within a range of a few millimeters or less than 1 mm relative to the coupling body. The current-carrying element has a contact tip at one end.

[0033] According to at least one embodiment, each current collector has a spring. The spring is arranged between the coupling body and the current-carrying element. The spring exerts a spring force in the second direction. This spring force pushes the coupling body and the current-carrying element away from each other. Thus, in the assembled state of the current-tapping arrangement, the current-carrying element, and in particular the contact tip, is reliably pressed against the associated conductor in the busbar. Furthermore, small tolerances can be compensated for.

[0034] According to at least one embodiment, the current collectors each have a cable opening for receiving a cable. Each current collector has an electrical connection that is linked to the cable opening. This electrical connection is electrically connected to the current-carrying element via a sliding contact. Thus, an electrical connection from the conductor in the busbar, via the current-carrying element and the sliding contact, to the cable opening is possible. In the ready-to-use state, the cable is electrically connected to the sliding contact. The cable is electrically connected to the functional element to transmit current and / or control signals from the busbar to the functional element.

[0035] According to at least one embodiment, the current tap assembly has an earth contact. During operation, this contact is electrically connected to earth potential. The earth contact is, for example, identical in design to the other current collectors. For instance, the earth contact is positioned so that, when the current tap assembly is mounted in the busbar, it is the first to make contact with the corresponding conductor in the busbar.

[0036] According to at least one embodiment, a functional insert comprises a current tap arrangement according to at least one embodiment. The functional insert includes an electrical functional element that is electrically connected to the current tap arrangement. The functional element is, for example, a luminaire that, during operation, emits light from a light-emitting surface facing away from the busbar. Alternatively or additionally, the functional element is a loudspeaker, a sensor, a fire detector, and / or a motion detector. Different functional elements can be combined in one functional insert. In particular, the functional insert includes one or more light-emitting diodes.

[0037] According to at least one embodiment, a busbar system has a functional insert according to at least one embodiment. According to one embodiment, the busbar system has a busbar extending elongated along a third direction. The busbar includes the mounting rail and the conductor holder with electrical conductors. The mounting rail is, for example, made of a metal and the conductor holder of an electrically insulating plastic.

[0038] According to at least one embodiment, the conductors are arranged side by side along the first direction. In particular, the electrical conductors are formed along a plane that runs parallel to the light-emitting surface of the functional insert. In particular, the conductors are elongated along the third direction. The contact tips can come into contact with the electrical conductors at any position along the third direction and touch the respective associated electrical conductor. The current-carrying elements then extend along the second direction transversely to the conductors up to the sliding contact. The current-carrying elements extend in a straight line along the second direction between the conductors and the functional insert.

[0039] According to at least one embodiment, each current collector is in contact with one of the lines along the second direction to form an electrical connection. Thus, electrical current and / or a data signal can be transmitted from the line to the current collector and the current tap arrangement. According to other embodiments, there are more lines than current collectors. Consequently, according to these embodiments, there are lines that are not contacted by a current collector.

[0040] According to at least one embodiment, some of the lines are electrical power lines and others are data lines. For example, in the operational state, the electrical power lines are connected to one or more electrical power grids. The data lines are, in particular, connected to control devices that, for example, provide control signals or can receive data from the functional unit.

[0041] According to at least one embodiment, by sliding the current collectors along the first direction, it is possible to select which conductor the respective current collector is in contact with in the operational state. Thus, for each functional insert, it is possible to select, for example, which electrical network each functional insert is to be connected to, immediately before installation in the busbar. In particular, no rewiring or similar is necessary for this. Simply sliding one or more current collectors relative to the housing into a predefined position is sufficient to assign the current collector to a conductor.

[0042] According to at least one embodiment, the lines corresponding to the first state are lines of different phases of a general power supply. The lines corresponding to the second state are, in particular, lines of an emergency power supply.

[0043] According to at least one embodiment, a method for electrically contacting a current tap arrangement according to the invention with a current rail extending elongate along a third direction is specified.

[0044] According to at least one embodiment, the current tap assembly is inserted into the busbar. This insertion occurs in a second direction. A housing cover of the current tap assembly is moved in the opposite direction. This exposes a contact tip of the current tap assembly. The contact tip is then pressed against an electrical conductor of the busbar with a force in the second direction. Before the current tap assembly is inserted into the busbar, the contact tip is concealed behind the housing cover and thus protected. As the current tap assembly is inserted into the busbar, the housing cover is moved relative to the contact tip in the opposite direction due to contact with the busbar. This exposes the contact tip, allowing it to come into contact with the electrical conductor and form an electrically conductive connection.The contact tip is pressed against the electrical conductor in the mounting direction of the current tap arrangement and, in particular, in the mounting direction of a functional element that is connected to the electrical conductors by means of the current tap arrangement.

[0045] According to at least one embodiment, the contact tip is moved along a first direction before the current tap assembly is inserted into the busbar. This movement selects one of the busbar's multiple electrical conductors, against which the contact tip is subsequently pressed. This makes it easy to select which electrical conductors the current tap assembly is electrically connected to.

[0046] According to at least one embodiment, a force is exerted on the contact tip in the second direction by means of a spring. The spring presses the contact tip against the conductor to ensure reliable contact between the conductor and the contact tip.

[0047] Further advantages, features, and developments will emerge from the following examples, which are explained in conjunction with the figures. Identical, similar, or equivalent elements can be marked with the same reference symbols across different figures.

[0049] Figure 1 shows a functional insert 101 for a busbar system 103 ( Figure 3The functional insert 101 is, for example, a lamp or other electrical device. The functional insert 101 has, in particular, one or more functional elements 132 ( Figure 3 The functional element is, for example, a luminaire that emits light from a light-emitting surface facing away from a busbar 133 during operation. The functional element could also be a loudspeaker, a sensor, a fire alarm, and / or a motion detector. Different functional elements can be combined in a functional insert. In particular, the functional insert has one or more light-emitting diodes.

[0050] The functional insert 101 is mechanically and electrically connected to the busbar 133 ( Figure 2) connectable. For electrical connection of the functional insert 101 to the busbar 133, a current tap arrangement 100 is attached to a rear side 135 of the functional insert 101. The rear side 135 is, in particular, opposite a light emission side 136. The functional insert 101 extends elongatedly along a third direction 113.

[0051] For mechanical coupling with the busbar 133, for example the mounting systems 137 are provided.

[0052] The current tap arrangement 100 is electrically connected to the functional insert 101 by means of cables not explicitly shown, in order to transmit electrical energy and / or data signals to the functional insert 101.

[0053] Figure 2Figure 1 shows the busbar 133 according to an exemplary embodiment. The busbar 133 has a mounting rail 102. The mounting rail 102 is, for example, made of a metal and serves for the mechanical fixing of the functional insert 101. A cable holder 134 is attached within the mounting rail 102. The cable holder 134 is, in particular, made of an electrically insulating material, for example, a plastic.

[0054] The busbar 133 extends elongatedly along the third direction 113. The conductor holder 134 also extends elongatedly along the third direction 113. In addition, the conductor holder 134 has a transverse extension in a first direction 111. The first direction 111 and the third direction 113 are perpendicular to each other and, in particular, are perpendicular to each other.

[0055] The line holder 134 holds a plurality of lines 138. The lines 138 are specifically designed to transmit electrical current and / or data signals. For example, the lines 138 are connected to a power grid or multiple power grids and to control devices via signal transmission.

[0056] The conductors 138 are held side by side along the first direction 111 by the conductor holder 134. According to exemplary embodiments, the conductors 138 are, for example, held offset from each other along a second direction 112. The three directions 111, 112 and 113 are, in particular, each perpendicular to one another.

[0057] Figure 3 Figure 1 shows the busbar system 103 according to an exemplary embodiment. The functional insert 101 with the current tap arrangement 100 is inserted into the busbar 133 from a side opposite the conductor holder 134. In particular, the installation is carried out along the second direction 112.

[0058] Figure 4 shows in more detail the area of ​​the busbar system 103 in which the electrical connection between the busbar 133 and the functional insert 101 is formed by means of the current tap arrangement 100.

[0059] Figure 5 Figure 1 shows the current tap arrangement 100 according to an exemplary embodiment. The current tap arrangement 100 has a housing 104. The housing is, for example, made of a plastic. The housing 104 is open, in particular, in the second direction 112 towards the top. A housing cover 119 is arranged on the open side of the housing 104. The housing cover 119 is coupled to the housing 104 so as to be displaceable relative to the housing 104 along the second direction 112. Figure 5 shows the housing cover 119 in its position spaced apart from the housing 104. In this position are current-conducting elements 127 ( Figure 6) within the housing 104 and the housing cover 119 and are thus protected. In particular, the current-carrying elements 127 are protected from mechanical impacts and bending or breaking of the current-carrying elements 127 can be avoided.

[0060] The housing cover 119 has a plurality of recesses 125. The current-carrying elements 127 are guided through the recesses 125 when the housing cover 119 is pressed towards the housing 104. Protective elements 139 are provided at each of the recesses 125. The protective elements project, in particular, along the second direction 112. The protective elements 139 serve to guide and stabilize the current-carrying elements 127 and to provide electrical insulation between the current-carrying elements 127.

[0061] The current-tapping arrangement 100 has a plurality of current collectors. A first current collector 106 and a second current collector 107 are accessible along the third direction 113 from one side of the housing 104. From a side opposite along the third direction 113, a third current collector 108 and a fourth current collector 109 are accessible ( Figure 8The first current collector 106 and the second current collector 107 are each coupled either so as to be displaceable relative to the housing 104 and relative to each other along the first direction 111, or so as to be fixed relative to the housing 104 or relative to each other. For example, the first current collector 106 and the second current collector 107 are displaceable relative to the housing 104 along the first direction 111 in order to select which conductor 138 the first current collector 106 makes contact with and which conductor 138 the second current collector 107 makes contact with when the current tap arrangement 100 is located in the conductor rail 133.

[0062] The housing 104 is provided with a receptacle 140. The receptacle 140 has a plurality of fastening hooks 141. The current tap assembly 100 can be connected to the functional insert 101 by means of the fastening hooks 141. For example, the fastening hooks 141 are each spring-loaded and engage a corresponding recess in the functional insert 101.

[0063] Figure 6 shows the current tap arrangement 100 and the cable holder 134.

[0064] The housing 104 of the current tap assembly 100 is coupled to the receptacle 140 by means of locking hooks 142.

[0065] The housing has a structure 124. The structure 124 consists, for example, of grooves or projections on the housing. The first current collector 106 and the second current collector 107 each have, for example, an engagement element 143 that interacts with the structure 124. The structure 124 defines predetermined positions for the first current collector 106 and the second current collector 107.

[0066] The first pantograph 106 is movable along the first direction 111, for example, to be assigned to one of the lines 138, which corresponds, for example, to one of the three phases of a standard power supply. For example, the first pantograph 106 is assigned to the first phase L1, the second phase L2, or the third phase L3. The lines 138 in the line holder 134 are connected to different power networks accordingly. For example, the second pantograph 107 is in a position to be connected to a neutral conductor. Regardless of which phase the first pantograph 107 is assigned to, the second pantograph 107 remains connected to the neutral conductor.

[0067] If the functional unit 101 is to be connected to an emergency power grid, for example, the first pantograph 106 and the second pantograph 107 are moved together further in the first direction 111. Then the second pantograph 107 is also moved to a different position than in Figure 6 The neutral conductor is arranged as shown, in order to be connected to a corresponding emergency power network.

[0068] To facilitate correct insertion of the current tap assembly 100, the conductor holder 134 has a projection 144. The projection 144 is arranged, in particular, along the first direction 111 on one side of the conductor holder 134. The housing 104 has a corresponding recessed area 145 in which the projection 144 is located during operation. On the side opposite the first direction 111, the conductor holder 134 has a recess 146. The housing 104 has a corresponding rib 147. During operation, the rib 147 is located within the recess 146. The projection 144, the recessed area 145, the recess 146, and the rib 147 form, in particular, a mechanical coding that enables correct insertion of the current tap assembly 100 into the conductor holder 104 and prevents incorrect insertion.

[0069] Figure 7Figure 1 shows the current tap assembly 100 and the conductor holder 134 in a position where an electrical connection is established between the conductors 138 and the current collectors 106 and 107. By pressing the current tap assembly 100, the housing cover 100 comes into contact with the conductor holder 134. The housing 104 is pushed further towards the conductor holder 134, thereby displacing the housing cover 119 towards the housing 104. As a result, the current-carrying elements 127 emerge from the protective elements 139 and protrude beyond them. The current-carrying elements 127 then come into contact with the previously selected conductor 138.

[0070] Figure 8 shows one side of the current tap arrangement 100, which is opposite the side that is in Figure 7The third current collector 108 and the fourth current collector 109 are, for example, accessible from this side. The third current collector 108 and the fourth current collector 109 are, for example, immovable relative to each other. The third current collector 108 and the fourth current collector 109 are, in particular, displaceable relative to the housing 104 along the first direction 111. Thus, for example, a data line or signal line can be selected from the lines 138 to which the third current collector 108 is connected. By fixing the two current collectors 108 and 109 to each other, the line 138 to which the fourth current collector 109 is connected is also predetermined. Further current collectors 148 can be provided, which, for example, realize a contact with earth potential. According to the exemplary embodiment, the further current collector 148 is identical in construction to the other current collectors 106 to 109.According to further embodiments, the further current collector 148 is designed differently.

[0071] Figure 9 The current tap arrangement 100 is shown without the housing cover 119.

[0072] The housing 104 has a spring receptacle 149 in which a spring can be arranged. The spring pushes the housing cover 109 away from the housing 104 in the second direction 112.

[0073] A housing insert 105 is arranged within the housing 104. The housing insert 105 is mechanically coupled to the first current collector 106 and the second current collector 107. In a first state, the housing insert 105 is coupled to the housing 104 in a fixed position relative to it. In a second state, the housing insert 105 is displaceable relative to the housing 104 along the first direction 111.

[0074] The first pantograph 106 is movable relative to the housing insert 105 along the first direction 111 in the first state. Thus, in the first state, the assigned line 138 to the first pantograph 106 can be selected by moving it. The second pantograph 107 is fixed immovably to the housing insert 105. Therefore, in the first state, the second pantograph 107 is assigned to one of the lines 138, regardless of how the first pantograph 106 is moved.

[0075] In a second state, the first current collector 106 couples with the housing insert 105 in such a way that the first current collector 106 can only be moved relative to the housing 104 together with the housing insert 105. Thus, in the second state, the first current collector 106 and the second current collector 107 are fixedly connected to the housing insert 105 relative to each other. The first current collector 106 and the second current collector 107, together with the housing insert 105, can be moved relative to the housing 104 along the first direction in order to select the conductor 138 for both the first current collector 106 and the second current collector 107.

[0076] A further housing insert 118 is arranged within the housing 104. The third current collector 108 and the fourth current collector 109 are connected to this further housing insert 118. The third current collector 108 and the fourth current collector 109 are, for example, fixed to the further housing insert 118 so as to be immovable relative to each other. The third current collector 108 and the fourth current collector 109, together with the further housing insert 118, are displaceable along the first direction 111 relative to the housing 104. Displacement of the further housing insert 118 serves to select the conductor for the third current collector 108 and the fourth current collector 109.

[0077] Other types of release of displacements and coupling of displacements of the individual pantographs 106 to 109 are also possible.

[0078] Figure 10Figure 1 shows the housing 104 according to an exemplary embodiment. The housing 104 has a retaining element 110. The retaining element 110 is spring-loaded in the manner of a snap hook. In particular, the retaining element is movable along the second direction 112 on one side.

[0079] Figures 11 and 12 Figure 1 shows the housing insert 105 according to an exemplary embodiment. The housing insert 105 has a recess 150 corresponding to the retaining element 111. When the retaining element 110 is at least partially arranged in the recess 150, the retaining element 110 prevents movement of the housing insert 105 relative to the housing 104 by abutting the retaining element 110 against the boundary walls of the recess 150. When the retaining element 110 is deflected from a rest position and is no longer arranged in the recess 150, movement of the housing insert 105 relative to the housing 104 along the first direction 111 is released.

[0080] The housing insert 105 has a guide 151. The guide 151 is designed, for example, in the form of a bridge and is configured to guide the movement of the housing insert 105 relative to the housing 104 along the first direction 111.

[0081] The housing insert 105 has a first receptacle 152 for the first current collector 106. The housing insert 105 has a second receptacle 153 for the second current collector 107. The first receptacle 152 is designed such that the first current collector 106 is fixed immovably to the housing insert 105 along the second direction 112 and the third direction 113. Movement of the first current collector 106 relative to the housing insert 105 is permitted along the first direction 111 by the shape of the first receptacle 152.

[0082] The second receptacle 153 is designed so that the second pantograph 107 can be firmly connected to the housing insert 105.

[0083] The housing insert 105 has a current collector bracket 115. The current collector bracket 115 is resiliently designed along the second direction 112. The current collector bracket 115 is designed to resist movement of the first current collector 106 along the first direction. The first receptacle 152 has a stop 116 at its end facing the second receptacle 153 along the first direction. The current collector bracket 115 and the stop 116 are positioned relative to each other such that the first current collector 106 can be held between them and fixed relative to the housing insert 105. Movement in the first direction 111 is blocked by the stop 116. The current collector bracket 115 resists movement against the first direction 111.In particular, the resistance between the housing insert 105 and the housing 104 when the housing insert 105 is moved relative to the housing 104 is less than the resistance exerted by the current collector bracket 115. Thus, movement of the housing insert 105 together with the first current collector 106 and the second current collector 107 is possible when the first current collector 106 is held by the current collector bracket 115 and the stop 116. Only when the housing insert 105 re-engages with the retaining element 110 does the resistance to the movement of the housing insert 105 increase, and thus a force opposite to the first direction 111 on the first current collector 106 is redirected into a downward pressure on the current collector bracket 115. This allows movement of the first current collector 106 relative to the housing insert 105 via the current collector bracket 115.

[0084] The first recording 152 and the second recording 153, for example, have locking hooks or other elements to hold the first pantograph 106 and the second pantograph 107.

[0085] Figure 13 Figure 1 shows the housing 104 with the housing insert 105 inserted. The retaining element 110 is arranged in the recess 150 and holds the housing insert 105 along the first direction relative to the housing 104.

[0086] Furthermore, a lid guide 154 is shown. The lid guide 154 directs the movement of the housing lid 119 relative to the housing along the second direction 112.

[0087] Figure 14Figure 1 shows the housing insert 105 in the housing 104 with the first current collector 106 and the second current collector 107 inserted. The housing insert 105 is attached to the housing 104 in such a way that the first current collector 106 and the second current collector 107 are reliably attached to the housing 104. The first current collector 106 and the second current collector 107 are arranged offset from each other along the third direction 113. In particular, the first current collector 106 projects beyond the housing 104 in the opposite direction to the third direction 113. Thus, a point of application for displacement is created. The second current collector 107 is set back.

[0088] Figure 15Figure 1 shows the further housing insert 118 according to an exemplary embodiment. The further housing insert 118 has a third receptacle 155 for the third current collector 108. The further housing insert 118 has a fourth receptacle 156 for the fourth current collector 109. The third receptacle 155 and the fourth receptacle 156 each have locking hooks or similar features to reliably hold the third current collector 108 and the fourth current collector 109, respectively, on the further housing insert 118.

[0089] Figure 16 Figure 1 shows the further housing insert 118 with the third pantograph 108 and fourth pantograph 109 mounted. Pantograph guides 157 are formed on the pantographs 108 and 109 to guide the movement of the pantographs relative to the housing 104 along the first direction 111.

[0090] Figure 17Figure 1 shows a further housing insert 118 mounted in housing 104. This further housing insert 118 securely holds the third current collector 108 and the fourth current collector 109 within housing 104. The third current collector 108 and the fourth current collector 109 each project beyond the housing 104 in the third direction 113. This provides a point of leverage for displacement.

[0091] Figure 18Figure 1 shows a current collector, which can be the first current collector 106, the second current collector 107, the third current collector 108, the fourth current collector 109, or a further current collector. In particular, the current collectors 106 to 109 are identical in construction. The current collector 106 to 109 has a coupling body 126, which is made of a plastic material. The coupling body 126 can be coupled to the housing insert 105 and / or the further housing insert 118. The current collector 106 to 109 has the current-carrying element 127, which is made of an electrically conductive material. The current-carrying element 127 has a contact tip 120. The contact tip serves to contact the conductor 138 and to form an electrical connection between the current collector 106 to 109 and the conductor 138.

[0092] The current collector 106 to 109 has a cable opening 129. The cable opening 129 serves to receive an electrically conductive cable or wire. One end of the electrically conductive cable is inserted into the cable opening 129, for example. The opposite end is electrically connected to the functional insert 101, for example.

[0093] The coupling body 126 has the customer guide 157. Furthermore, the coupling body 126 has a clearance 121. The clearance serves as a counterpart to the receptacles 152, 153, 155, 156.

[0094] The current collector 106 to 109 has an actuating element 114. The actuating element serves to deflect the retaining element 110 from its rest position when the current collector 106 to 109 is arranged in the housing insert 105 against the stop 116. For example, the actuating element 114 is part of a base of the current collector 106.

[0095] Figure 19Figure 1 shows a section view of part of the current-tapping arrangement 100. The first current collector 106 and the second current collector 107 are held in their respective mountings 152 and 153 along the second direction 112 and the third direction 113. As shown in Figure 106, the first current collector 106 and the second current collector 107 are held in their respective mountings 152 and 153 along the second direction 112 and the third direction 113. Figure 19 It is evident that the first pantograph 106 and the second pantograph 107 are arranged offset from each other along the third direction 113. This allows for an increase in the distance between the two current-carrying elements 127 when assembled and ready for operation. The first pantograph 106 and the second pantograph 107 are arranged offset from each other along the second direction 112. In particular, the first pantograph 106 and the second pantograph 107 are arranged offset from each other in the same way as the conductors in the busbar are arranged offset from each other in two planes along the second direction 112.

[0096] Figures 20 and 21Each figure shows a sectional view of the current tap assembly 100 in its assembled, ready-to-use state. A spring 128 is arranged between the coupling body 126 and the current-carrying element 127. The spring exerts a spring force in the second direction 112. The functional insert 101 is mechanically coupled to the mounting rail 102 and is immobile, particularly in the opposite direction 112. Thus, the current tap assembly 100 is also stably mounted in the mounting rail 102. The spring 128 therefore presses the current-carrying element 127 in the second direction 112 against the conductor 138. The housing cover 119 is deflected from its rest position in the opposite direction 112, thus exposing the contact tip 120.

[0097] An electrical connection 130 is provided between the cable opening 129 and the current-carrying element 127. The electrical connection 130 is, for example, made of an electrically conductive material such as a metal and is, in particular, at least partially resilient. A conductor can be inserted into the cable opening 129 along the third direction 113 and is mechanically clamped, for example, by the electrical connection 130. An electrical connection is formed by the contact between the conductor and the electrical connection 130.

[0098] A sliding contact 131 is formed between the electrical connection 130 and the current-carrying element 127. This allows the electrical current or voltage to be transferred from the current-carrying element 127 to the electrical connection 130 and vice versa. The sliding contact 131 enables the movement of the current-carrying element 127 relative to the rest of the current collector 106, and in particular to the electrical connection 130 and the cable opening 129.

[0099] The busbar system 103 comprises the busbar 133 and the functional insert 101 with the current tap arrangement 100. The functional insert 101 is, in particular, a luminaire or a luminaire arrangement that can be used in the busbar system 103. The busbar 133 has the mounting rail 102, to which the functional insert 101 can be attached.

[0100] The busbar 133, which can also have several busbar elements, has electrical and data supply lines running along its entire length. At various points, it is possible to tap power for supplying various electrical components using the current tap arrangement 100. Additionally, it is possible to connect non-power lines 138, such as data transmission lines or control lines, using the current tap arrangement 100. Due to the arrangement of the line holder 134 in the mounting rail 102 such that the lines 138 run along the third direction 113 and are arranged side by side along the first direction 111, it is possible to dispense with a separate channel, for example in the mounting rail or in the functional insert 101, in which the lines are conventionally arranged.

[0101] The conductors 138 of the busbar system 103 can be arranged along their entire length in the conductor holder 134 without additional insulation. This eliminates the need for stripping insulation at the points where the functional insert 101 is to be contacted. Due to the special arrangement of the current collectors 106 to 109 in the housing 104 and the housing cover 119, leakage currents or other interactions between the current-carrying elements 127 are sufficiently prevented without additional insulation. The individual conductors 138 are adequately protected from each other due to their positioning in the conductor holder 137, for example, by the staggered arrangement along the second direction of adjacent conductors 138 relative to each other.

[0102] Furthermore, the busbar system 103 allows for the integration of a variety of lines, for example, for normal power supply, emergency power supply, control lines, or data transmission, while flexibly defining the system's external dimensions. Deviations from the desired dimensions of the mounting rail 103, for example along the first direction 111, are avoidable. The busbar system 133 is specifically designed to meet the emergency lighting standard DIN 6059822 with a luminaire insert that is also suitable for normal operation. Due to the adjustability of the current collectors 106 to 109 relative to the housing 104, the same current tap arrangement 100 and thus the same functional insert 101 can be used as for normal lighting supply.

[0103] The conductors 138 are arranged in the conductor holder 134 such that, while maintaining clearance and creepage distances, the current collectors 106 to 109 can be shifted. Phase selection in the normal network between phases L1, L2, L3 with N is possible. Selection from the emergency power network L', N' and L'', N" is also possible. Furthermore, shifting between DALI 1 and DALI 2 is possible, for example, between two different data networks, control networks, or other networks that do not primarily supply electrical energy. The conductors 138 for phases L1, L2, L3, L', and L" are located in a common plane. The conductors for DALI selection, i.e., for DALI 1 and DALI 2, are located in a separate common plane. The two planes are spaced apart along the second direction 112. This allows, for example, a small installation space while maintaining all clearance and creepage distances.The pantographs 106 to 109 are moved, in particular, by hand without tools.

[0104] The current tap assembly 100 has a plurality of current collectors 106 to 109. Four current collectors can be provided, or more or fewer. The current collectors 106 to 109 are inserted into the base housing 104, and in particular into the housing insert 105 and the further housing insert 118. The receptacles 152, 153, 155, and 156, as well as the collector guide 157 and the clearance 121, serve to receive and guide the current collectors. Each current collector 106 to 109 has a cable opening 129, also called a conductor receptacle. Wiring can be done here. The current guide element 127 serves for electrical contact with one of the conductors 138.

[0105] The protective elements 139 are provided on the spring-loaded housing cover 119 to protect the current-carrying elements 127 and, in particular, the contact tips 120. The protective elements 139 also serve to ensure compliance with the specified clearances and creepage distances and to guarantee correct positioning. The correct positioning of the current tap assembly 100 relative to the conductor holder 134 is further ensured by the projection 144 and the web 147. This also provides 180° rotation protection, preventing incorrect connection.

[0106] For DALI adjustment, the third current collector 108 and the fourth current collector 109 are connected to the additional housing insert 118. The two current collectors 108 and 109 can only be adjusted together. This allows adjustment from D1+ and D1- to D2+ and D2-.

[0107] The first pantograph 106 and the second pantograph 107 are positioned in the housing insert 105. For the selection of the normal operating current network, the second pantograph 107 is positioned so that it always contacts the neutral conductor N. The first pantograph 106 is movable relative to this between phases L1, L2, and L3. For the emergency network selection, the current tap arrangement 100 is designed such that when the first pantograph 106 reaches the position corresponding to L3, a further movement of the first pantograph 106 in the first direction 111 moves the housing insert 105 along with it. Thus, the second pantograph 107 is automatically moved from its position N simultaneously with the first pantograph 106. This moves the first pantograph 106 and the second pantograph 107 from positions L3 and N to L' and N'. Further movement to L" and N" is possible.In the last area, only the movement of the first pantograph 106 and the second pantograph 107 together is possible.

[0108] When the first current collector 106 is moved from the position assigned to L3, the retaining element 110 is pushed forward. This releases the housing insert 105 for movement. It can then be moved to L' and N' and further to L" and N".

[0109] The second pantograph 107 is attached to the housing insert 105. When L' and N' are pushed back to L3 and N, the pantograph bracket 115 serves to hold the first pantograph 106 relative to the housing insert 105. The retaining element 110 requires less force to overcome when moving in the opposite direction 111 than the pantograph bracket 115. This allows the position L3 and N to be reached. To further move the first pantograph 106 from L3 to L2, the pantograph bracket 115 is overcome. The position N of the second pantograph 107 is held. The housing insert 105 is positioned against a side wall 122 in the opposite direction 111. Figure 10 ) of the housing 104. A displacement of the housing insert 105 relative to the housing 104 in the opposite direction 111 is therefore not possible.

[0110] By arranging the conductors 138 in the conductor holder 134 in one plane, it is sufficient to move the current collectors 106 to 109 along a single direction 111 to select the conductor.

[0111] The current tap arrangement 100 enables the use of the function insert 101 for all applications, in particular for standard applications, emergency lighting, and DALI control. No special variants with their own wiring are necessary. This ensures compliance with DIN EN 60598222 using the busbar system 102, without requiring different function inserts 101. This reduces costs and the number of variants. Furthermore, users have complete freedom to choose which function inserts 101 to use.

[0112] Figures 22 to 27 demonstrate the principle of selecting the different lines 138.

[0113] In Figure 22The first pantograph 106 is arranged in a position where it contacts line 138a, i.e., L1. The second pantograph 107 is arranged in a position where it contacts line 138d, i.e., N. The third pantograph 108 and the fourth pantograph 109 can only be moved together and are arranged so that lines 138b and 138c are contacted, i.e., D1+ and D1-.

[0114] Figure 23 This shows the phase selection after the first pantograph 106 has been moved one position. The first pantograph 106 has been moved to the position where it contacts line 138e, i.e., L2. This movement of the first pantograph 106 has not changed the position of the second pantograph 107. The third pantograph 108 and the fourth pantograph 109 were also not moved by this movement.

[0115] Figure 24This shows the phase selection, in which the first pantograph 106 was moved to the position corresponding to L3. The first pantograph 106 now contacts line 138f. Moving the first pantograph 106 did not change the position of the second pantograph 107, the third pantograph 108, or the fourth pantograph 109.

[0116] Figure 25 This shows the phase selection where an emergency power network L' and N' was selected. The first pantograph 106 was moved from position L3 to position L', so that the first pantograph 106 now contacts line 138g. This movement of the first pantograph 106 also leads to a movement of the second pantograph 107, so that it now contacts line 138h. The two pantographs 106 and 107 are now coupled together, so they can only be moved together.

[0117] Figure 26The selection of a further emergency power network L" and N" is shown. Moving the first pantograph 106 to the position corresponding to L" causes the second pantograph 107 to also move. Thus, the first pantograph 106 now contacts line 138i and the second pantograph 107 contacts line 138k.

[0118] Figure 27 This shows the change in selection on the second line level. In particular, this selection, which is achieved by moving the third pantograph 108 and the fourth pantograph 109, is independent of the phase selection. The third pantograph 108 and the fourth pantograph 109 can only be moved together. Thus, moving, for example, D1+ to D2+ also results in D1- being moved to D2-. After moving, the third pantograph 108 and the fourth pantograph 109 therefore contact lines 138m and 138n.
