Description

[0001] The present invention relates to a modular mounting panel system for an electrical distribution board.

[0002] Modular devices or installation devices, such as miniature circuit breakers, residual current devices, time switches, D and DO fuses, DO switch-fuse units, built-in switches, and built-in sockets, are designed for installation in electrical distribution boards or service distribution boards. These distribution boards can be found in virtually every electrified building today.

[0003] Conventional DIN rail-mounted devices are specifically described by the German standard DIN 43 880. These devices, with standardized sizes, are mounted on DIN rails in a distribution cabinet. Power is tapped from the devices conventionally via screw or spring-loaded terminals.

[0004] US 3,213,403 A1 also discloses a busbar system comprising multiple busbars within a housing. Plug-in openings are provided along the housing so that the fingers of a plug-in unit can be inserted into the housing to tap off power.

[0005] DE 10 2019 109 638 B4 also discloses a switch cabinet arrangement with a multi-pole touch protection module, in which several busbars are accommodated in a touch-safe manner and accessible via contact openings for device adapters. The touch protection module has a modular housing with at least one central module or several identical central modules arranged in series.

[0006] Other similar devices are known from US 11 784 468 B2 and DE 20 2013 003 925 U1.

[0007] Based on this prior art, it is an object of the present invention to provide a device carrier module for a mounting panel system for an electrical distribution board and a mounting panel system for an electrical distribution board in order to improve the user-friendliness taking into account the desired applications.

[0008] This object is achieved by a device carrier module according to claim 1, a mounting panel system according to claim 14, and a mounting panel system according to claim 17. Claims 2 to 13 relate to particularly advantageous implementations of the device carrier module according to claim 1. Claims 15 and 16 relate to particularly advantageous implementations of the mounting panel system according to claim 14.

[0009] According to the present invention, a device carrier module for a mounting panel system for an electrical distribution board comprises a first side wall and a second side wall, which are arranged on opposite sides of the device carrier module and each extend at least partially or completely in a longitudinal direction or substantially in a longitudinal direction of the device carrier module. The device carrier module can be made at least partially or completely from an electrically insulating material (e.g., from a plastic). The device carrier module comprises one or more conductor insertion tracks, which extend in the longitudinal direction or substantially in the longitudinal direction of the device carrier module and are designed for inserting and / or releasably fastening one or more conductor rails.If the device carrier module comprises at least two conductor insertion tracks, each two adjacent conductor insertion tracks are separated from each other by an electrically insulating separating track. However, it is also possible for the device carrier module to comprise only one conductor insertion track, so that there are no two adjacent conductor insertion tracks of the device carrier module and the above feature is therefore not present. For example, the device carrier module comprises two conductor insertion tracks for inserting two conductor rails of a single-phase connection, four conductor insertion tracks for inserting four conductor rails corresponding to the neutral conductor N and the three outer conductors L1, L2, L3 of a three-phase connection, or a multiple of three conductor insertion tracks for inserting a multiple of three conductor rails, each corresponding to the outer conductors L1, L2, L3 of a three-phase connection. The conductor rails can in particular be electrical conductors, preferably copper conductors.Alternatively or additionally, the one or more conductor insertion paths can be configured for the insertion and / or releasably securing of one or more other lines, in particular signal lines or data lines. The signal lines or data lines can be inserted, in particular, into the free conductor insertion paths, i.e., into the conductor insertion paths into which no conductor rails are inserted. This allows the functionality of the distributor to be expanded and its user-friendliness to be further increased.

[0010] The device carrier module further comprises one or more electrically insulating covers for covering, preferably for covering in a touch-safe manner, the one or more conductor insertion tracks or the one or more conductor rails inserted into the one or more conductor insertion tracks.

[0011] In addition, the device carrier module comprises one or more first slots; and one or more second slots, which are arranged at a predetermined distance in the longitudinal direction from the one or more first slots. In particular, each second slot can be arranged at a predetermined distance in the longitudinal direction from a corresponding first slot. The predetermined distance between a first slot and a second slot can in particular correspond to a height of a DIN rail mounted device module, which can be inserted into an operating position between a first connection module and a second connection module, which can each be plugged into the first or second slot on the device carrier module. In the operating position, the DIN rail mounted device can be fastened to a device carrier module or to the mounting panel system or locked to it. The number of first orThe number of second slots can correspond to a number of installation rows of the electrical distribution board and, in particular, can be equal to a number of DIN rails to which the device carrier modules can be latched, as described in more detail below. For example, each device carrier module can comprise three first and three second slots, four first and four second slots, five first and five second slots, or six first and six second slots, corresponding to three, four, five, or six parallel DIN rails.

[0012] The device carrier module further comprises one or more first transverse connecting elements and one or more second transverse connecting elements which are designed such that the device carrier module and a first further device carrier module can be detachably fastened or latched or automatically latched to one another via the one or more second transverse connecting elements of the device carrier module and the one or more first transverse connecting elements of the first further device carrier module, so that: the first further device carrier module is arranged offset or shifted relative to the device carrier module in a transverse direction, wherein the transverse direction runs perpendicular or substantially perpendicular to the longitudinal direction, and a conductor insertion track of the device carrier module and an adjacent conductor insertion track of the first further device carrier module are separated from one another by an electrically insulating separating track.At least part of this electrically insulating partition wall can be formed by at least part of the second side wall of the device carrier module and at least part of the first side wall of the first additional device carrier module; alternatively, this electrically insulating partition wall can comprise at least part of the second side wall of the device carrier module and at least part of the first side wall of the first additional device carrier module. When the device carrier module and the first additional device carrier module are fastened to one another, the second side wall of the device carrier module can at least partially or completely abut the first side wall of the first additional device carrier module.

[0013] The device carrier module according to the invention enables flexible, simple, safe, and lightning-fast assembly of an electrical distribution board or a mounting panel for an electrical distribution board. Depending on the desired application, one or more device carrier modules can be provided, each with a corresponding number of conductor insertion tracks. In the case of multiple device carrier modules, these can be fastened to one another using the corresponding cross-connection elements. Subsequently, for example, one or more connection modules can be plugged into the one or more first or second slots on the respective device carrier modules, and one or more DIN rail device modules can be inserted into their respective operating positions by moving them relative to the one or more plugged-in connection modules along an insertion direction toward the device carrier modules.Using the plug-in connection modules, the DIN rail device modules can be electrically connected to other DIN rail device modules, to conductor rails inserted into the device carrier module, or to a neutral conductor rail arranged in or on a device carrier module, as described in more detail below. This allows the electrical distribution board to be installed flexibly, easily, safely, and quickly, without the need for special installation tools or special installation skills. In particular, no power taps via screw or spring-loaded terminals and no complicated conductor routing between different DIN rail devices are required, as is the case with conventional electrical distribution boards. The electrical distribution board can therefore be installed without any problems, even by a layperson or user of the electrical distribution board.Furthermore, an electrical distribution board assembled in this way can be expanded as needed by attaching additional equipment carrier modules and / or reduced in size by removing already attached equipment carrier modules. This improves user-friendliness while taking the desired applications into account. Furthermore, the equipment carrier module according to the invention can be manufactured industrially, meaning that the pre-assembly of the electrical distribution board can be industrialized. This makes the electrical distribution board more cost-effective, as the user only needs to assemble the modules.

[0014] In a preferred embodiment, the one or more first slots and the one or more second slots each comprise one or more device carrier plug-in elements, each of which is arranged in or on a separating strip. The one or more first slots and / or the one or more second slots or the one or more device carrier plug-in elements can be designed as plug-in recesses or plug-in holes into which corresponding connecting plug-in elements of a connecting module, which are designed as plug-in projections, can be inserted. The plug-in recesses or plug-in holes are preferably L-shaped. Conversely, however, the connecting plug-in elements of the connecting module can also be designed as plug-in recesses or plug-in holes and the slots or device carrier plug-in elements of the device carrier module can be designed as plug-in projections.The arrangement of the device carrier plug-in elements in or on a separating strip enables a particularly secure, compact, and space-saving structure of the device carrier module. The L-shape of the plug-in recesses allows, for example, the connecting plug-in elements of a connecting module, which are designed as plug-in projections, to be inserted into the respective L-shaped plug-in recesses using an L-shaped movement. For example, the connecting module can first be inserted along the insertion direction and then shifted or moved along the longitudinal or transverse direction relative to the device carrier module. This enables particularly simple, stable, and secure attachment of the connecting module to the respective device carrier module.

[0015] In a preferred embodiment, the one or more first transverse connecting elements comprise one or more projections and the one or more second transverse connecting elements comprise one or more recesses. Alternatively or additionally, the one or more first transverse connecting elements comprise one or more recesses and the one or more second transverse connecting elements comprise one or more projections. In particular, the one or more first transverse connecting elements can be arranged on the first side wall and / or the one or more second transverse connecting elements can be arranged on the second side wall. Preferably, the one or more projections are T-shaped. Thus, the first further device carrier module can be fastened to the device carrier module, e.g.by arranging the first additional device carrier module offset in the transverse direction relative to the device carrier module and displacing or moving it relative to the device carrier module along the insertion direction, so that in the fastened state, the one or more projections engage in the one or more recesses. Due to the T-shape of the one or more projections, in particular, the first additional device carrier module can be fixed relative to the device carrier module in the longitudinal direction and in the transverse direction, so that a secure attachment of the first additional device carrier module to the device carrier module is achieved.

[0016] The device carrier module preferably comprises one or more first longitudinal connecting elements and one or more second longitudinal connecting elements, which are designed such that the device carrier module and a second further device carrier module can be detachably fastened or latched or automatically latched to one another via the one or more second longitudinal connecting elements of the device carrier module and the one or more first longitudinal connecting elements of the second further device carrier module, so that the second further device carrier module is arranged offset in the longitudinal direction relative to the device carrier module. Particularly preferably, the one or more first longitudinal connecting elements are arranged on a first edge section, e.g. on a lower edge section, of the device carrier module, and the one or more second longitudinal connecting elements are arranged on a second edge section opposite the first edge section, e.g.on an upper edge section of the device carrier module. The device carrier module and the second further device carrier module can in particular be fastened to one another in the longitudinal direction in such a way that the conductor insertion tracks of the device carrier module are extended or continued in the longitudinal direction by the conductor insertion tracks of the second further device carrier module. Thus, the conductor rails arranged in the conductor insertion tracks of the device carrier module and the conductor rails arranged in the conductor insertion tracks of the second further device carrier module can also be fastened to one another and / or brought into contact with one another in order to form conductor rails extended in the longitudinal direction. Thus, several device carrier modules can be fastened to one another in the longitudinal direction and electrically connected in order to enlarge the resulting mounting panel of the electrical distributor and, depending on the desired application, e.g.Mount a larger number of connection modules and / or DIN-rail device modules on the mounting panel. This allows for flexible and individually adaptable installation of the electrical distribution board.

[0017] For example, the one or more first longitudinal connecting elements can comprise one or more fastening pins or pin elements, and the one or more second longitudinal connecting elements can comprise one or more fastening slots or openings. Alternatively or additionally, the one or more first longitudinal connecting elements can comprise one or more fastening slots or openings, and the one or more second longitudinal connecting elements can comprise one or more fastening pins or pin elements. When the device carrier module and the second additional device carrier module are fastened to one another, the one or more fastening pins can preferably engage in the one or more fastening slots in a form-fitting manner. In this way, a particularly simple, stable, and secure assembly of several device carrier modules to one another in the longitudinal direction is achieved.

[0018] In a preferred embodiment, the one or more electrically insulating covers comprise one or more coding elements which are arranged and / or shaped and / or dimensioned such that they each code a corresponding DIN rail mounted device module from one or more different DIN rail mounted device modules and / or an orientation of a corresponding DIN rail mounted device module, wherein the one or more coding elements are preferably designed as one or more projections for engaging, in particular positive engagement, in one or more recesses of the corresponding DIN rail mounted device module or as one or more recesses for engaging, in particular positive engagement, one or more projections of the corresponding DIN rail mounted device module.Alternatively or additionally, the one or more coding elements can be configured to each encode a current or a voltage of a corresponding DIN rail device module.

[0019] The one or more coding elements can in particular be arranged and / or shaped and / or dimensioned such that: if the DIN rail device module has a first orientation relative to the device carrier module, the DIN rail device module can be inserted into the operating position and can preferably be locked to the device carrier module in the operating position; and if the DIN rail device module has a second orientation relative to the device carrier module that is different from the first orientation, the DIN rail device module cannot be inserted into the operating position. The second orientation of the DIN rail device module can in particular be rotated by 180° about the insertion direction relative to the first orientation.This means that the DIN rail device module having the second orientation can be rotated by 180° around the insertion direction relative to the DIN rail device module having the first orientation, in particular such that the input and output contacts of the DIN rail device module are arranged interchangeably. This ensures that the DIN rail device module can only be inserted into the operating position when it has the correct orientation relative to the device carrier module, so that in particular the desired connection of the input or output contacts of the DIN rail device module can be established, e.g. with conductor elements of the respective connection modules. This provides protection against incorrect insertion of the DIN rail device modules, in particular an anti-twist device. This prevents damage to the DIN rail device system due to inadvertent insertion of the DIN rail device module with an incorrect orientation.This is particularly advantageous when the DIN rail device system is installed by a layperson or user of the DIN rail device system. This further increases the user-friendliness of the DIN rail device system. The coding elements described above for different currents and voltages also ensure that only suitable DIN rail device modules, especially DIN rail device modules with a suitable current and voltage, can be installed at each position on the mounting panel system. Incorrect installation of unsuitable switching devices or DIN rail device modules can thus be completely eliminated, further increasing user-friendliness and safety.

[0020] Alternatively or additionally, the one or more coding elements can be arranged and / or shaped and / or dimensioned such that: the DIN rail device module can be inserted into the operating position and can preferably be locked to the device carrier module in the operating position; a further DIN rail device module can be inserted into a further operating position; however, the DIN rail device module cannot be inserted into the further operating position (of the further device carrier module) and / or the further DIN rail device module cannot be inserted into the operating position (of the device carrier module). This ensures that each DIN rail device module can only be inserted into its corresponding operating position (or into one of several corresponding operating positions) and cannot be accidentally inserted into the operating position of another DIN rail device module.This provides protection against incorrect insertion of the DIN rail device modules, particularly preventing them from being mixed up. This prevents damage to the DIN rail device system due to incorrect arrangement of the DIN rail device modules during installation. This is particularly advantageous when the DIN rail device system is installed by a layperson or user of the DIN rail device system. This further increases the user-friendliness of the DIN rail device system.

[0021] In a preferred embodiment, the center lines of any two adjacent conductor insertion tracks of the device carrier module are equally spaced from each other. The distance can be, for example, 18 mm, corresponding to the pitch unit according to the DIN 43 880 standard. In this respect, the mounting panel system according to the invention can be compatible with conventional distribution boards and, for example, can be installed in existing control cabinets. However, the distance can also be greater than 18 mm, for example 27 mm, to provide more space for mounting larger DIN rail-mounted devices, depending on the desired application, or less than 18 mm to enable a more compact and space-saving distribution board. The equal distance between the center lines of the device carrier module simplifies the production of the device carrier module and reduces the cost of the distribution board.If different distances between centerlines are required depending on the desired application, this can still be achieved, e.g. by attaching one equipment carrier module with a first distance between the centerlines and another equipment carrier module with a second distance between the centerlines that is different from the first distance, as described in more detail below.

[0022] The mounting panel system can further comprise a plurality of conductor rails. The plurality of conductor rails are preferably plate-shaped and / or strip-shaped. Thus, the conductor rails can be inserted or secured particularly securely into the conductor insertion tracks and can be contacted particularly securely by the conductor ends of the conductor elements of the connection modules. Furthermore, the plate-shaped conductor rails can be produced efficiently and cost-effectively.

[0023] Preferably, the mounting panel system further comprises one or more conductor elements or tapping springs or contact fingers, each having a first conductor end and a second conductor end, wherein the one or more conductor elements are fastened to the one or more conductor rails, in particular to one or more notches in the one or more conductor rails, such that the second conductor ends contact the one or more conductor rails and the first conductor ends protrude from openings in the one or more covers. In particular, the one or more conductor elements can be arranged so as to be rotatable relative to the one or more conductor rails, in particular so as to be rotatable about the respective second conductor ends.

[0024] Particularly preferably, the one or more conductor elements are arranged so as to be elastically deformable relative to the one or more conductor rails and can assume respective rest positions, so that when the one or more conductor elements are moved, in particular rotated, out of their respective rest positions, a restoring force acts on the one or more conductor elements, which moves, in particular rotates, the one or more conductor elements back into their respective rest positions. Alternatively or additionally, the one or more conductor elements can be spring-loaded with respect to the one or more conductor rails, wherein the spring force corresponds to the restoring force. Preferably, the one or more conductor elements are perpendicular to the one or more conductor rails in their respective rest positions. The conductor elements can, for example,When plugging a feed-in module onto the device carrier module, the connectors are inserted into the connection housing of the feed-in module, so that the first conductor ends of the conductor elements can be contacted through corresponding openings in the connection housing. Since the conductor elements are arranged so they can rotate relative to the corresponding conductor rails about the second conductor ends, the first conductor ends can also be preloaded against one or more contacts of a DIN rail device module by means of spring forces, as described in more detail below.

[0025] Preferably, the plurality of conductor rails each have a fastening section for fastening the conductor rail to a corresponding conductor insertion track, e.g., by means of a locking or snap-in connection, and a contact section for contacting the second conductor end of a corresponding conductor element. The conductor rails can have different thicknesses; however, in order for the conductor rails to be used with uniform device carriers and with uniform conductor elements of a predetermined height, for each conductor rail, a bottom side of the fastening section, with which the conductor rail is fastened to the conductor insertion track, and a top side of the contact section, to which the corresponding conductor element is fastened, must have a predetermined distance from one another.By using conductor rails of smaller thickness, material and costs can be saved, while by using conductor rails of greater thickness, the stability and current-carrying capacity of the conductor rails can be improved.

[0026] In a preferred embodiment, the device carrier module comprises one or more locking units for locking or automatically locking the respective device carrier module to one or more parallel top-hat rails, preferably in such a way that the one or more top-hat rails run parallel or substantially parallel to the transverse direction. This allows the mounting panel system to be attached to the top-hat rails particularly easily, quickly, and securely. Furthermore, the connection modules and the DIN rail-mounted device modules, which are plugged or inserted onto the device carrier modules, do not themselves need to be attached to the top-hat rails, thereby further simplifying the assembly of the electrical distribution board. The locking units can, in particular, be designed and dimensioned such that the device carrier modules can be inserted into existing control cabinets with top-hat rails, e.g.to several, in particular three, parallel DIN rails of 35 mm width with a rail-to-rail center distance of 150 mm.

[0027] Preferably, the one or more locking units each comprise a first locking element; a second locking element that is arranged to be movable back and forth relative to the first locking element along the longitudinal direction of the device carrier module between an arrangement position for arranging the device carrier module relative to a top-hat rail, so that the top-hat rail can be positioned between the first locking element and the second locking element, and a clamping position for clamping or clamping the top-hat rail between the first locking element and the second locking element; and a locking spring element that is configured to preload the second locking element in the direction of the first locking element, preferably preloading the second locking element in any position in the direction of the first locking element. The locking spring element can be formed integrally with the second locking element and, for example, made of plastic in order to save manufacturing costs.This means that the mounting panel system can be attached to the DIN rails particularly easily, quickly and securely, which further increases user-friendliness.

[0028] According to the present invention, a mounting panel system for an electrical distribution board comprises the device carrier module and the first further device carrier module, wherein the device carrier module and the first further device carrier module are releasably fastened to one another via the one or more second cross-connecting elements of the device carrier module and the one or more first cross-connecting elements of the first further device carrier module.

[0029] In a preferred embodiment, a distance between centerlines of two adjacent conductor insertion tracks of the device carrier module is different from a distance between centerlines of two adjacent conductor insertion tracks of the first additional device carrier module. This allows DIN rail device modules of a first width to be mounted on the device carrier module, and DIN rail device modules of a second width to be mounted on the first additional device carrier module, wherein the second width is different from the first width. Alternatively, the distance between centerlines of two adjacent conductor insertion tracks of the device carrier module can be equal to the distance between centerlines of two adjacent conductor insertion tracks of the first additional device carrier module. Thus, the electrical distributor can be flexibly assembled from the same or different modules, depending on the desired application.

[0030] In a preferred embodiment, the number of conductor insertion tracks of the device carrier module is different from the number of conductor insertion tracks of the first additional device carrier module. This allows DIN rail device modules with a total of a first number of poles to be mounted on the device carrier module, and DIN rail device modules with a total of a second number of poles to be mounted on the first additional device carrier module, wherein the second number of poles can be different from the first number of poles. Alternatively, the number of conductor insertion tracks of the device carrier module can be equal to the number of conductor insertion tracks of the first additional device carrier module. Thus, the electrical distributor can be flexibly assembled from the same or different modules depending on the desired application.Particularly preferably, the number of conductor insertion paths of the device carrier module multiplied by the distance between center lines of two adjacent conductor insertion paths of the device carrier module is equal to the number of conductor insertion paths of the first additional device carrier module multiplied by the distance between center lines of two adjacent conductor insertion paths of the first additional device carrier module. Thus, the device carrier module and the first additional device carrier module can have the same dimension in the transverse direction, making the production, storage, and transport of the device carrier modules more efficient and cost-effective.

[0031] According to the present invention, a mounting panel system for an electrical distribution board comprises the device carrier module and the second additional device carrier module, wherein the device carrier module and the second additional device carrier module are releasably fastened to one another via the one or more second longitudinal connecting elements of the device carrier module and the one or more first longitudinal connecting elements of the second additional device carrier module. Preferably, the distance between centerlines of two adjacent conductor insertion tracks of the device carrier module is equal to the distance between centerlines of two adjacent conductor insertion tracks of the second additional device carrier module, and preferably, the number of conductor insertion tracks of the device carrier module is equal to the number of conductor insertion tracks of the second additional device carrier module.Thus, the one or more conductor insertion tracks of the device carrier module can be extended or continued in the longitudinal direction by the one or more conductor insertion tracks of the second additional device carrier module. Thus, the one or more conductor rails arranged in the one or more conductor insertion tracks of the device carrier module and the one or more conductor rails arranged in the one or more conductor insertion tracks of the second additional device carrier module can be fastened to one another and / or brought into contact with one another to form conductor rails extended in the longitudinal direction. In particular, the mounting panel system can comprise the device carrier module, the first additional device carrier module, and the second additional device carrier module. Thus, the electrical distributor can be flexibly mounted depending on the desired application.

Fig. 4A shows a view from the bottom direction in Fig. 2 of the modular DIN rail mounted device system and the modular mounting panel system. Fig. 4B shows a view from the upper direction in Fig. 2 of the modular DIN rail mounted device system and the modular mounting panel system. Fig. 5A and Fig. 5B each show a perspective view of the modular DIN rail device system and the modular mounting panel system with the DIN rail device modules 1 removed. Fig. Figure 5C shows a top view of the modular DIN rail device system and the modular mounting panel system with the DIN rail device modules 1 removed.

[0034] In this embodiment, the modular mounting panel system comprises three equipment carrier modules 3: one in Fig. 2 left-hand device carrier module 3 (hereinafter referred to as “left device carrier module 3”), a Fig. 2 centrally arranged equipment carrier module 3 (hereinafter referred to as “central equipment carrier module 3”) and a Fig. 3 right-hand device carrier module 3 (hereinafter referred to as “right device carrier module 3”). The left and central device carrier modules 3 as well as the central and right device carrier modules 3 are each arranged in the transverse direction (horizontal direction in Fig. 2) are attached to each other to form a mounting panel or mounting panel system for an electrical distribution board. The device carrier modules 3 each contain three locking units for attaching the mounting panel to three parallel DIN rails 7.

[0035] In this embodiment, the modular DIN rail device system further comprises three installation rows, with an upper and a middle (in Fig. 2) Installation row with one fuse switch module 1a, one residual current device module 1b and six single-pole circuit breaker modules 1c as well as a lower (in Fig. 2) Installation row with a fuse switching device module 1a, a residual current device module 1b and a three-pole DIN rail mounted device module 1d are shown. The DIN rail mounted device modules 1 are each inserted in their respective operating positions between two connection modules 2 which are plugged onto the device carrier modules 3. In this embodiment, each of the three installation rows contains four connection modules 2: an infeed module 2a which is mounted or plugged onto the left device carrier module 3, a first transverse displacement module 2b which is mounted on the left and central device carrier modules 3, a second transverse displacement module 2b which is mounted on the central and right device carrier modules 3, and an output module 2c which is mounted on the right device carrier module 3.

[0036] In this embodiment, the left device carrier module 3 and the central device carrier module 3 each comprise four conductor insertion tracks 31, while the right device carrier module 3 comprises six conductor insertion tracks 31. The conductor insertion tracks 31 each extend in the longitudinal direction (vertical direction in Fig. 2). The distance between the center lines of two adjacent conductor insertion tracks 31 is, for example, 27 mm for the left device carrier module 3 and the central device carrier module 3 and 18 mm for the right device carrier module 3. In this case, each of the three device carrier modules 3 has the same dimension in the transverse direction, namely 4 × 27 mm = 6 × 18 mm = 108 mm.

[0037] Four conductor rails 5 are arranged in the four conductor insertion tracks 31 of the left device carrier module 3, corresponding to the neutral conductor N and the three phase conductors L1, L2, and L3 of a three-phase connection. The conductor rails 5 are covered by electrically insulating covers 36 and are therefore Fig. 1A to 5B not visible (but see Fig. 22A and Fig. 22B, where the electrically insulating covers 36 are removed). The power is transmitted to the conductor rails 5 via a power feed block with four input terminals (clamping screws) 8, which in this embodiment is mounted on an upper section of the left device carrier module 3 (in Fig. 2 top left). For each installation row, the current is conducted from the conductor rails 5 via conductor elements 23, which are fastened to the conductor rails 5 and arranged in the feed-in module 2a, through the fuse switching device module 1a to the first transverse displacement module 2b. The first transverse displacement module 2b conducts the current further along the transverse direction (perpendicular to the longitudinal direction) from the left device carrier module 3 to the central device carrier module 3. From there, the current is conducted through the residual current device module 1b to the second transverse displacement module 2b. The second transverse displacement module 2b conducts the current further along the transverse direction from the central device carrier module 3 to the right device carrier module 3. From there, the current is conducted through the DIN rail installation device modules 1 installed on the right device carrier module 3 (i.e. the six miniature circuit breaker modules 1c of the upper or middle installation row orThe three-pole DIN rail device module 1d of the lower installation row is routed to the respective output module 2c and from there via output terminals 9 to the consumer devices. The right device carrier module 3 further comprises output conductor elements, which each connect the consumer devices to a neutral conductor bar 6 in order to close the circuit between the distributor and the consumer devices. The neutral conductor bar 6 can be arranged at least partially within the output module 2c, as described in more detail below (see ). Fig. 22A to 23D). Alternatively, the neutral conductor rail 6 can also be inserted into a corresponding neutral conductor insertion track of a device carrier module 3, which runs in the transverse direction.

[0038] In Fig. 5A to 5C it can also be seen that the connection modules 2 have coding pins 27 for engaging in corresponding coding slots 15a, 15b of the DIN rail device modules 1a to 1d (see Fig. 27A and 27D to 27F). As in Fig. 5C by dashed arrows, the coding pins 27 of two opposite connection modules 2 (each plugged into a first slot 35a and a corresponding second slot 35b) for the central device carrier module 3 are arranged relative to each other in the longitudinal direction (from top to bottom in Fig. 5C: vertical pins) are arranged to code the residual current device module 1b; for the left device carrier module 3 relative to each other in a diagonal direction (from top left to bottom right in Fig. 5C: diagonal pins) to code the fuse switch module 1a; and for the right device carrier module 3 in an opposite diagonal direction (from top right to bottom left in Fig. 5C: counter-diagonal pins) are arranged to code the miniature circuit breaker modules 1c and the three-pole DIN rail-mounted device module 1d, respectively. When the respective DIN rail-mounted device module 1a to 1d is in the operating position, the coding slots 15a, 15b are arranged in the longitudinal direction, the diagonal direction, or the opposite diagonal direction, as shown in Fig. 27A and 27D to 27F. Furthermore, Fig. 5A to 5C that the electrically insulating covers 36 may contain coding elements 361. Specifically, the electrically insulating cover 36 shown in Fig. 5A to 5C, two coding elements 361 are arranged at the bottom right to code the additional DIN rail mounted device 1d. These are shown as two in the top view of Fig. 5C, rectangular projections are formed for engaging corresponding recesses of the further DIN rail device module 1d. However, the coding elements can have shapes other than rectangles in plan view, e.g., squares, triangles, circles, and ellipses, in order to code corresponding DIN rail device modules or their orientations in the operating position.

[0039] Fig. Figure 6A shows a cross-sectional view along AA in Fig. 2. Fig. 6B shows the enlarged section X from Fig. 6A. Fig. 6C shows the enlarged section Y from Fig. 6B. The DIN rail device module 1 comprises a DIN rail device functional unit (arranged inside the DIN rail device module 1, not shown), an electrically insulating DIN rail device housing 11, one or more first contacts 13a, which are arranged on a first side (right side in Fig. 6A, Fig. 6B) of the DIN rail device module 1, and one or more second contacts 13b, which are arranged on a second side (left side in Fig. 6A, Fig. 6B) of the DIN rail device module 1, which is opposite the first side (see also Fig. 27A, Fig. 27B and Fig. 27C). The connection module 2 comprises an electrically insulating connection housing 21, one or more connection plug-in elements 22 for plugging or detachably fastening the connection module 2 onto the mounting panel or onto one or more device carrier modules 3 and for detaching the connection module 2 from the mounting panel or from the one or more device carrier modules 3, as well as one or more conductor elements 23, each having a first conductor end 231a and a second conductor end 231b, wherein the first conductor end 231a and the second conductor end 231b can each be contacted via a corresponding opening in the connection housing 21 (see Fig. 17A to Fig. 19D).

[0040] Fig. 6A further shows a touch protection cover 182 (or cover hood 182 or panel 182) of a switch cabinet in which the DIN rail device system is installed. In this case, the touch protection cover 182 rests on the hook elements 18 or on corresponding support surfaces of the hook elements 18 of the DIN rail device modules 1. The touch protection cover 182 has openings from which the DIN rail device modules 1 protrude in their respective operating positions, as shown in Fig. 6A. The openings of the touch protection cover 182 have the same or essentially the same size and shape as the cross-sections (in plan view) of the corresponding DIN rail device modules 1. The DIN rail device modules 1 can be dimensioned such that they can be installed in conventional switch cabinets with conventionally dimensioned touch protection covers 182. If, however, the DIN rail device modules 1 have different dimensions, the dimensions of the openings of the touch protection cover 182 can be adapted to the dimensions of the DIN rail device modules 1, so that the DIN rail device modules 1 can be installed in the switch cabinet with the adapted touch protection cover 182. Please note that in the remaining figures, except Fig. 6A the contact protection cover 182 was omitted.

[0041] In Fig. 6A and Fig. 6B, in particular, a feed-in module 2a and a transverse displacement module 2b are shown, each of which is plugged onto the mounting plate as described above, as well as a DIN rail device module 1, which is arranged to be movable relative to the two connection modules 2 along an insertion direction and can be inserted into an operating position by moving along the insertion direction towards the mounting panel and can be removed from the operating position by moving along the insertion direction away from the mounting panel. In this embodiment, the insertion direction (vertical direction in Fig. 6A, Fig. 6B) perpendicular to the mounting panel. In this embodiment, the DIN rail device module 1 is inserted between the feed-in module 2a and the transverse displacement module 2b and is locked in the operating position with the two connection modules 2, so that the first contacts 13a (e.g., input contacts) of the DIN rail device module 1 contact the first conductor ends 231a of a conductor element 23 arranged in the feed-in module 2a, and the second contacts 13b (e.g., output contacts) of the DIN rail device module 1 contact the first conductor ends 231a of a conductor element 23 arranged in the transverse displacement module 2b. The feed-in module 2a is an example of the connection module 2, and the transverse displacement module 2b is an example of the further connection module 2.

[0042] In this embodiment, the feed module 2a comprises first contact spring elements 26a which are configured such that when the DIN rail device module 1 is in the operating position (as in Fig. 6A, Fig. 6B), the first contacts 13a of the DIN rail device module 1 and the first conductor ends 231a of the conductor elements 23 of the feed-in module 2a are prestressed against each other by means of spring forces of the first contact spring elements 26a. In this embodiment, the first contact spring elements 26a are fastened on the one hand to the connection housing 21 and on the other hand to the first conductor ends 231a of the conductor elements 23 of the feed-in module 2a. The spring forces of the first contact spring elements 26a in this embodiment are perpendicular to the insertion direction (i.e. the spring forces act in Fig. 6A, Fig. 6B in the horizontal direction). Furthermore, the transverse displacement module 2b comprises second contact spring elements 26b, which are configured such that, when the DIN rail device module 1 is in the operating position, the second contacts 13b of the DIN rail device module 1 and the first conductor ends 231a of the conductor elements 23 of the transverse displacement module 2b are biased against each other by means of spring forces of the second contact spring elements 26b. In this embodiment, the second contact spring elements 26b are fastened on the one hand to the connection housing 21 and on the other hand to the first conductor ends 231a of the conductor elements 23 of the transverse displacement module 2b. The spring forces of the second contact spring elements 26b are also perpendicular to the insertion direction. Fig. 6B and Fig. 6C also shows the locking projection 233 formed on the first conductor end 231a of the conductor element 23 and the locking recess 212 formed on the connecting housing 21. The locking projection 233 is designed as a locking hook in this case. The locking recess 212 is designed as an opening (locking opening) in the connecting housing 21. The locking projection 233 is designed to lock into the locking recess 212, so that the spring force of the contact spring element 26b prevents the conductor element 23 or the first conductor end 231a from slipping out of the connecting housing 21 when the DIN rail device module 1 is removed from the operating position.

[0043] The DIN rail device module 1 further comprises a first side surface 17a and first hook elements 18a, each of which is arranged on the first side (right side in Fig. 6A, Fig. 6B) of the DIN rail device module 1, wherein the first hook elements 18a each have a first end portion 181a which is spaced from the first side surface 17a. The feed-in module 2a has projection elements 28 in this embodiment. When the DIN rail device module 1 is in the operating position (as in Fig. 6A, Fig. 6B), the projection elements 28 of the feed module 2a are arranged between the first side surface 17a and the first end sections 181a of the first hook elements 18a and are actuated by means of the spring forces of the snap spring elements 25 (see Fig. 10 and corresponding description) and / or by means of the spring forces of the first contact spring elements 26a against the first end sections 181a of the first hook elements 18a. Furthermore, the DIN rail-mounted device module 1 has a second side surface 17b and second hook elements 18b, each of which is arranged on the second side (left side in Fig. 6A, Fig. 6B) of the DIN rail device module 1, wherein the second hook elements 18b each have a second end portion 181b that is spaced from the second side surface 17b. In this embodiment, the transverse displacement module 2b has projection elements 28. When the DIN rail device module 1 is in the operating position, the projection elements 28 of the transverse displacement module 2b are arranged between the second side surface 17b and the second end portions 181b of the second hook elements 18b and are pretensioned against the second end portions 181b of the second hook elements 18b by means of the spring forces of the second contact spring elements 26b.

[0044] Fig. Figure 7A shows a cross-sectional view along BB in Fig. 2. Fig. 7B shows the enlarged section I from Fig. 7A. In Fig. 7A and Fig. 7B are in particular a first transverse displacement module 2b (left in Fig. 7A and Fig. 7B) and a second transverse displacement module 2b (right in Fig. 7A and Fig. 7B), each of which is plugged onto the mounting plate, as well as a DIN rail device module 1, which is inserted into the operating position between the first transverse displacement module 2b and the second transverse displacement module 2b. The first transverse displacement module 2b is an example of the connecting module 2, and the second transverse displacement module 2b is an example of the further connecting module 2.

In Fig. 8A and Fig. 8B shows, in particular, a transverse displacement module 2b and an output module 2c, each plugged onto the mounting plate, as well as a DIN rail device module 1 inserted into the operating position between the transverse displacement module 2b and the output module 2c. The transverse displacement module 2b is an example of the connection module 2, and the output module 2c is an example of the further connection module 2.

[0046] Fig. 9 shows a cross-sectional view along DD in Fig. 2. In this embodiment, the device carrier module 3 comprises three locking units for locking onto three parallel top-hat rails 7. The locking units each comprise a first locking element 38a; a second locking element 38b which is arranged to be movable back and forth relative to the first locking element 38a along the longitudinal direction between an arrangement position for arranging the device carrier module 3 relative to a top-hat rail 7, such that the top-hat rail 7 can be positioned between the first locking element 38a and the second locking element 38b, and a clamping position for clamping or clamping the top-hat rail 7 between the first locking element 38a and the second locking element 38b; and a locking spring element 39 which is configured to preload the second locking element 38b in the direction of the first locking element 38a in each position. Fig. 9 shows, in particular, three locking units: in the central and right-hand locking units, the second locking element 38b is in the arrangement position, while in the left-hand locking unit, the second locking element 38b is in the clamping position. The second locking element 38b further comprises an engagement element 381 into which a user can engage with a tool, e.g., a screwdriver, to move the second locking element 38b from the clamping position to the arrangement position against the spring force of the locking spring element 39 in order to release the device carrier module 3 or the mounting panel from the top-hat rail 7.

[0047] Fig. 10 shows a cross-sectional view along EE in Fig. 2. In this embodiment, the respective right-hand connection module 2a comprises one or more snap projections 24, which are designed as snap hooks 24, and one or more snap spring elements 25, and the DIN rail device module 1 has one or more snap recesses 14 or undercuts 14. When the DIN rail device module 1 is in the operating position, as in Fig. 10, the one or more snap projections 24 engage positively in the one or more snap recesses 14 and are pre-tensioned by means of spring forces of the one or more snap spring elements 25 in the direction of the DIN rail device module 1. In this embodiment, the spring forces are perpendicular to the insertion direction, ie parallel to the mounting panel (horizontal in Fig. 10).

[0048] Fig. 11A and Fig. 11B each show a perspective view of a device carrier module 3 with plugged-on connection modules or, more precisely, feed-in modules 2a and with a power feed-in block arranged on an upper section of the device carrier module 3; this device carrier module 3 corresponds to the left device carrier module 3 in Fig. 2; Fig. 12A shows a side view from the right side of this equipment carrier module 3; Fig. 12B shows a top view of this equipment carrier module 3; and Fig. Figure 12C shows a side view of the left side of this equipment carrier module 3. Fig. 13A and Fig. 13B each show a perspective view of a device carrier module 3 without plugged-on connection modules 2 and without power feed block; this device carrier module 3 corresponds to the central device carrier module 3 in Fig. 2; Fig. 14A shows a side view from the right side of this equipment carrier module 3; Fig. 14B shows a top view of this equipment carrier module 3; and Fig. 14C shows a side view of the left side of this equipment carrier module 3. In the following, the left equipment carrier module 3 (from Fig. 11A to 12C) and the central device carrier module 3 (from Fig. 13A to 14C) are described together, since they essentially only differ in the power supply block of the left device carrier module 3.

[0049] The device carrier module 3 comprises a first side wall 33a and a second side wall 33b, which are arranged on opposite sides (left side and right side in Fig. 12B or 14B) of the device carrier module 3 and are each arranged in the longitudinal direction of the device carrier module 3 (vertical direction in Fig. 12B and 14B, respectively. In this embodiment, the device carrier module 3 comprises three first slots 35a and three second slots 35b, each comprising a plurality of device carrier plug-in elements 351, wherein the second slots 35b are each arranged at a predetermined distance in the longitudinal direction of the device carrier module 3 from the first slots 35a. The predetermined distance between a first slot 35a and a second slot 35b corresponds to a height of a DIN rail device module 1, which can be inserted into an operating position between a first connection module 2 and a second connection module 2, which can each be plugged onto the first slot 35a and second slot 35b, respectively.

[0050] In this embodiment, the device carrier plug-in elements 351 are designed as plug-in recesses into which corresponding connecting plug-in elements 22 of a connecting module 2, which are designed as plug-in projections, can be inserted. In particular, the device carrier plug-in elements 351 are designed as plug-in recesses that are L-shaped. Thus, the connecting plug-in elements 22 of a connecting module 2, which are designed as plug-in projections, can be inserted into the respective L-shaped plug-in recesses 351 by an L-shaped movement. This L-shaped movement is in Fig. 13A, Fig. 13B, Fig. 14B and Fig. 23A are marked by dashed arrows. The connecting module 2 is first inserted along the insertion direction (direction perpendicular to the plane of the paper in Fig. 14B) is moved toward the device carrier module 3 so that the connecting plug-in elements 22 are inserted into the device carrier plug-in elements 351. The connecting module 2 is then moved along the longitudinal direction of the device carrier module 3. In this way, the connecting module 2 is fastened to the device carrier module 3. Two opposing connecting modules 2, which are plugged into a first slot 35a or second slot 35b, are moved away from each other in opposite directions along the longitudinal direction of the device carrier module 3. In order to detach the two connecting modules 2 from the device carrier module 3 again, the connecting modules 2 must first be moved toward each other along the longitudinal direction and then moved away from the mounting panel along the insertion direction.However, if a DIN rail device module 1 is inserted in the operating position between the two connecting modules 2 and locked to the two connecting modules 2, the connecting modules 2 cannot be moved toward each other without first removing the DIN rail device module 1 from the operating position. This ensures particularly simple, stable, and secure attachment of the connecting modules 2 and the DIN rail device modules 1 to the device carrier modules 3.

[0051] In this embodiment, the device carrier module 3 comprises four conductor insertion tracks 31, which extend in the longitudinal direction of the device carrier module 3 and are designed for inserting and / or releasably fastening four conductor rails 5, wherein two adjacent conductor insertion tracks 31 are separated from each other by an electrically insulating separating track 32. In this embodiment, in the left device carrier module 3 (shown in Fig. 11A to 12C), a conductor rail 5 is inserted into each of the four conductor insertion tracks 31. However, the conductor insertion tracks 31 and conductor rails 5 are covered by the electrically insulating covers 36 and are therefore not visible; however, see Fig. 22A and Fig. 22B.

[0052] In this embodiment, the device carrier module 3 further comprises six first transverse connecting elements 34a, which are arranged on the first side wall 33a (left side wall in Fig. 12B or 14B) of the device carrier module 3, and six second cross-connecting elements 34b, which are arranged on the second side wall 33b (right side wall in Fig. 12B or 14B) of the device carrier module 3. The device carrier module 3 (e.g. the left device carrier module 3 in Fig. 2) and a first additional device carrier module 3 (e.g. the central device carrier module 3 in Fig. 2) can be releasably fastened to one another via the second transverse connecting elements 34b of the device carrier module 3 and the first transverse connecting elements 34a of the first further device carrier module 3, so that the first further device carrier module 3 is arranged offset in the transverse direction relative to the device carrier module 3. In this embodiment, the first transverse connecting elements 34a are designed as projections and the second lateral connecting elements 34b are designed as depressions, wherein the projections 34a are T-shaped (see in particular Fig. 12B and Fig. 14B, in which the T-shape is visible in the top view).

[0053] Furthermore, the device carrier module 3 in this embodiment comprises two first longitudinal connecting elements 37a, which are arranged at the lower edge section in Fig. 12B and 14B of the device carrier module 3, and two second longitudinal connecting elements 37b, which are arranged on the upper edge section in Fig. 12B of the device carrier module 3, wherein the device carrier module 3 and a second further device carrier module 3 can be releasably fastened to one another via the second longitudinal connecting elements 37b of the device carrier module 3 and the first longitudinal connecting elements 37a of the second further device carrier module 3, so that the second further device carrier module 3 is arranged offset relative to the device carrier module 3 in the longitudinal direction of the device carrier module 3. The first longitudinal connecting elements 37a are in Fig. 11A to 14C are concealed by covers and therefore not visible; however, see Fig. 22A and Fig. 22B. In this embodiment, the first longitudinal connecting elements 37a are designed as fastening pins and the second longitudinal connecting elements 37b as fastening slots. The fastening pins and the fastening slots are arranged parallel to or along the separating tracks 32 of the device carrier module 3. When the device carrier module 3 and the second further device carrier module are fastened to one another, the fastening pins of the device carrier module 3 engage in the fastening slots of the second further device carrier module, as described below in connection with Fig. 28 and Fig. 29A to 29C.

[0054] Fig. 15A and Fig. 15B each show a perspective view of a device carrier module 3 with plugged-on output modules 2c; Fig. 16A shows a side view of the right side of the equipment carrier module; Fig. 16B shows a top view of the device carrier module; Fig. Figure 16C shows a side view of the left side of the equipment carrier module; this equipment carrier module 3 corresponds to the right equipment carrier module 3 in Fig. 2. The right device carrier module 3 from Fig. 15A to 16C differs from the central device carrier module 3 essentially only by the additional coding elements 361 on the lower cover 36, which have already been described in connection with Fig. 5A to 5C. However, the coding elements 361 can be arranged at any position on the covers 36 of the one or more device carrier modules 3. In Fig. 15A, Fig. 16B and Fig. Figure 16C also shows the neutral conductor rail 6, which is described in more detail below.

[0055] Thus, identical or substantially identically designed device carrier modules 3 can be used to attach the power feed block with the input terminals 8, the conductor rails 5 and the feed module 1a for the power input (as in the case of the left device carrier module 3 in Fig. 2), or to attach the neutral conductor rail 6 and the output module 1c for the current output to it (as in the case of the right device carrier module 3 in Fig. 2), or to attach only connection modules 2b for the transverse displacement of the current on the mounting panel (as in the case of the central device carrier module 3 in Fig. 2). One and the same device carrier module 3 can thus be used (depending on the arrangement of this device carrier module 3 within the modular mounting panel system or depending on the combination of this device carrier module 3 with other modules) for the power supply, the transverse displacement of the power on the mounting panel, or the power output. This enables particularly efficient and cost-effective production of the device carrier modules and the electrical distribution board.

[0056] Fig. 17A shows a view from the lower direction in Fig. 2 of a connecting module 2, more specifically a transverse displacement module 2b, which in Fig. 1A, Fig. 1B is mounted on the left and central equipment carrier module. Fig. 17B shows a cross-sectional view along II in Fig. 17A. Fig. Figure 17C shows a cross-sectional view along I1-I1 in Fig. 17A. Fig. 17D shows a perspective view of the connection module 2, 2b from Fig. 17A. Fig. 17E shows a perspective view of the conductor elements 23 of the connection module 2, 2b from Fig. 17A.

[0057] The transverse displacement module 2, 2b from Fig. 17A to 17E comprises four conductor elements 23, each having a first conductor end 231a and a second conductor end 231b, wherein the first conductor ends 231a and the second conductor ends 231b can each be contacted via a corresponding opening in the connection housing 21. The four conductor elements 23 correspond to the three outer conductors L1, L2, L3 and the neutral conductor N. Each conductor element 23 can thus electrically connect a first contact 13a (or second contact 13b) of a DIN rail device module 1 to a first contact 13a (or second contact 13b) of another DIN rail device module 1, wherein the two DIN rail device modules 1 are arranged in their respective operating positions in the same installation row. The connection module 2, 2b from Fig. 17 therefore conducts the current transversely along the installation row (in the transverse direction) and is therefore also referred to as the transverse displacement module 2, 2b.

[0058] The openings of the connection housing 21, through which the first conductor ends 231a and the second conductor ends 231b of the conductor elements 23 can be contacted, are designed and dimensioned such that the first conductor ends 231a and the second conductor ends 231b cannot be contacted by a test finger according to the standard DIN EN 60529. The connection housing 21 thus has an electrically insulating contact protection 211, by which the first conductor ends 231a and the second conductor ends 231b are partially covered, as shown in Fig. 17A and Fig. 17D. In this embodiment, the contact protection 211 includes, in particular, an electrically insulating wall with sufficiently narrow openings for contacting the conductor ends 231a, 231b, so that a user cannot touch the contacts through the openings.

[0059] The conductor elements 23 of the connection module 2, 2b are also plate-shaped, as in Fig. 17E. The conductor elements 23 each have a connecting portion 232 which connects the respective first conductor end 231a to the respective second conductor end 231b, wherein the connecting portions 232 of the plurality of conductor elements 23 extend in the transverse direction (horizontal direction in Fig. 17A) and are arranged offset from each other in the transverse direction. Furthermore, the connecting portions 232 of the plurality of conductor elements 23 are in the insertion direction (vertical direction in Fig. 17A and Fig. 17E) spaced apart from each other.

[0060] In Fig. 17B also shows the contact spring elements 26 of the connection module 2, 2b, as described above. Furthermore, the connection module 2, 2b comprises grooves 29 into which the guide elements 19 of the DIN rail device module 1 (see Fig. 27A and Fig. 27D to 27F) can engage (or edges 29 against which the guide elements 19 can rest) in order to move the DIN rail device module 1 relative to the connection module 2 along the insertion direction. Furthermore, the connection module 2, 2b comprises connecting plug-in elements 22, which in this embodiment are designed as plug-in projections, as described above. Furthermore, in Fig. 17A and Fig. 17D the coding pins 27 can be seen.

[0061] Fig. 18A shows a view from the upper direction in Fig. 2 of a connecting module 2, more specifically a transverse displacement module 2b, which in Fig. 1A, Fig. 1B is mounted on the central and right equipment carrier modules. Fig. 18B shows a top view of the connection module 2, 2b from Fig. 18A. Fig. Figure 18C shows a cross-sectional view along JJ in Fig. 18A. Fig. Figure 18D shows a cross-sectional view along KK in Fig. 18A. Fig. 18E shows a perspective view of the connection module 2, 2b from Fig. 18A. Fig. 18F shows a perspective view of the conductor elements 23 of the connection module 2, 2b from Fig. 18A.

[0062] The transverse displacement module 2, 2b from Fig. 18A to 18F has similar features to the transverse displacement module 2, 2b from Fig. 17A to 17E. However, the transverse displacement module 2, 2b comprises Fig. 18A to 18F show three conductor elements 23, each having a first conductor end 231a, a second conductor end 231b, and a third conductor end 231c, wherein the first conductor ends 231a, the second conductor ends 231b, and the third conductor ends 231c can each be contacted via a corresponding opening in the connection housing 21. These three conductor elements 23 correspond to the three outer conductors L1, L2, L3. Each of these three conductor elements 23 can electrically connect a first contact 13a (or second contact 13b) of a DIN rail device module 1 to a first contact 13a (or second contact 13b) of another DIN rail device module 1 and to a first contact 13a (or second contact 13b) of yet another DIN rail device module 1, wherein the three DIN rail device modules are located in their respective operating positions in the same installation row. The connection module 2, 2b from Fig. 17 therefore also conducts the current transversely along the installation row. Furthermore, the transverse displacement module 2, 2b contains Fig. 18A to 18F a further conductor element 23 (fourth conductor element 23 from the right in Fig. 18A, Fig. 18B, Fig. 18E and Fig. 18F), the second conductor end 231b of which can be connected to the neutral conductor rail 6 via a fastening element 52, as described below in connection with Fig. 22A to 23D.

[0063] In Fig. 18C also shows the contact spring element 26 of the connection module 2, 2b, as described above. Fig. 18D further shows the snap projection 24 and the snap spring element 25. When a DIN rail device module 1 is in the operating position, a snap projection 24 engages in a corresponding snap recess 14 of the DIN rail device module 1 and is biased toward the DIN rail device module 1 by a spring force of the snap spring element 25. The snap projection 24 further comprises an engagement element 241 into which a user can engage with a tool, e.g., a screwdriver, to move the snap projection 24 in the opposite direction (away from the DIN rail device module 1) against the spring force of the snap spring element 25. In this way, the locking between the DIN rail device module 1 and the connection module 2 can be released, and the DIN rail device module 1 can then be removed from the operating position and moved away from the mounting panel along the insertion direction.In this embodiment, in particular the connection modules 2, which are plugged onto first slots 35a, have snap projections 24 and snap spring elements 25 (see . Fig. 10).

[0064] Fig. Fig. 19A shows a view from the bottom direction of a connection module 2, more specifically an output module 2c, which is in Fig. 1A, Fig. 1B is mounted on the right equipment carrier module 3. Fig. 19B shows a cross-sectional view along LL in Fig. 19A. Fig. 19C shows a top view of the connection module from Fig. 19A. Fig. 19E shows a perspective view of the connection module from Fig. 19A.

[0065] In this embodiment, the output module 2, 2c comprises six conductor elements 23, each with a first conductor end 231a and a second conductor end 231b. The first conductor ends 231a can each contact a contact 13 of a DIN rail device module 1 (see in particular Fig. 19B). The second conductor ends 231b are each configured to connect a consumer device, e.g., via a respective output terminal 9 (see Fig. 19C). Furthermore, the output module 2, 2c comprises six output conductor elements 23' (not fully shown), each having a first output conductor end 231a' and a second output conductor end 231b'. The first output conductor ends 231a' can each contact the neutral conductor rail 6, which is arranged at least partially within the output module 2c, as shown in Fig. 19A to 19D. The second output conductor ends 231b' are each configured to connect a consumer device, e.g., via a respective output terminal 9 (see Fig. 19C). Thus, each consumer device can be connected both to the second conductor end 231b of a conductor element 23 (corresponding to an outer conductor L1, L2, L3) and to the second output conductor end 231b' of an output conductor element 23' (corresponding to the neutral conductor N), thus closing the circuit between the distributor and the consumer device. In this embodiment, for example, six single-pole or two three-pole consumer devices can be connected to the output module 2c. The remaining properties of the output module 2, 2c are similar to those of the transverse displacement module 2, 2b as described above.

[0066] Fig. 20A shows a cross-sectional view along FF in Fig. 2. Fig. 20B shows the enlarged section K from Fig. 20A. Fig. 20C shows the enlarged section J from Fig. 20A. In Fig. 20A and Fig. 20B, in particular, a connection module 2 can be seen, which is plugged into a second slot 35b of a device carrier module 3. The connecting plug elements 22 of the connection module 2, which are designed as plug projections, are plugged into the device carrier plug elements 351 of the device carrier module 3, which are designed as plug recesses. In Fig. 20A and Fig. 20C also shows how two adjacent equipment carrier modules 3 are fastened to each other via the corresponding cross-connecting elements 34a, 34b.

[0067] Fig. 21A shows a cross-sectional view along GG in Fig. 2. Fig. 21B shows the enlarged section M from Fig. 21A. These figures particularly show a connection module 2, which is plugged into a first slot 35a of a device carrier module 3. The connecting plug elements 22 of the connection module 2, which are designed as plug projections, are plugged into the device carrier plug elements 351 of the device carrier module 3, which are designed as plug recesses.

[0068] Fig. 22A shows a perspective view of the modular mounting panel system with inserted conductor rails 5 and neutral conductor rails 6, wherein the covers 36 of the device carrier modules 3 have been removed. Fig. 22B shows a top view of the modular mounting panel system of Fig. 22A. These figures show in particular: the four parallel conductor insertion tracks 31 of the left and central device carrier module 3 and the separating tracks 32 arranged therebetween; the six parallel conductor insertion tracks 31 of the right device carrier module 3 and the separating tracks 32 arranged therebetween; the four conductor rails 5 inserted into the four conductor insertion tracks 31 of the left device carrier module 3; the associated four clamping screws 8 for supplying current to the conductor rails 5;the associated four conductor elements 23 per installation row, the second conductor ends 231b of which each contact the conductor rails 5 and which, when plugging the feed-in module 2, 2a onto the left device carrier module 3, can be inserted into the connection housing 21 of the feed-in module 2, 2a, so that the respective first conductor ends 231a can contact corresponding contacts 13 of the DIN rail devices 1 through corresponding openings in the feed-in module 2, 2a; the device carrier plug-in elements 351, which are arranged in or on the isolating strips 32; the neutral conductor rails 6, which are contacted by corresponding conductor elements 23 of the connection modules 2, 2b (see ; Fig. 18A to 18F, as well as the following Fig. 23A to 23D); the first side walls 33a and the second side walls 33b of the device carrier modules 3, wherein each two adjacent side walls 33a, 33b of two mutually fastened device carrier modules 3 form an electrically insulating separating strip 32; the first longitudinal connecting elements 37a (designed as fastening pins or pin elements) and the second longitudinal connecting elements 37b (designed as fastening slots or openings) of the device carrier modules 3; and marked with dashed arrows are the L-shaped and mutually opposite plug-in movements of two connection modules 2, which are each plugged into a first plug-in location 35a and a second plug-in location 35b. In Fig. 22B further shows that the center lines of two adjacent conductor insertion tracks of the left device carrier module are spaced apart by d1, the center lines of two adjacent conductor insertion tracks of the central device carrier module are also spaced apart by d1, and the center lines of two adjacent conductor insertion tracks of the right device carrier module are spaced apart by d2. For example, d1 can be 27 mm and d2 can be 18 mm, as described above.

[0069] In Fig. 23A to 23D, the neutral conductor rail 6 for the upper installation row can be seen in particular. The neutral conductor rail 6 is arranged at least partially within the corresponding output module 2, 2c, which is plugged into a second slot 35b of the right-hand device carrier module 3. The neutral conductor rail 6 is further connected via a fastening element 52 to a second conductor end 231b of a conductor element 23 of a connection module 2, 2b, which is plugged into the opposite first slot 35a.

[0070] Fig. 24A shows an embodiment of a conductor rail 5 and conductor elements 23 attached thereto. Fig. 24B shows the enlarged section W from Fig. 24A. The conductor rail 5 is plate-shaped or strip-shaped. The conductor elements 23 each have a first conductor end 231a and a second conductor end 231b and are each fastened to the conductor rail 5, in particular to the notch 51 of the conductor rail 5, by means of a fastening element 52 such that the second conductor end 231b contacts the conductor rail 5 and the conductor element 23 is arranged so as to be rotatable relative to the conductor rail 5 about the second conductor end 231b. If no external force acts on the conductor element 23, the conductor element 23 is perpendicular to the corresponding conductor rail 5, as shown in Fig. 24A, B. The conductor elements 23 can be inserted into the connection housing 21 of the feed-in module 2, 2a when plugging a feed-in module 2, 2a onto the device carrier module 3, so that the first conductor ends 231a of the conductor elements 23 can be contacted through corresponding openings in the connection housing 21. Since the conductor elements 23 are arranged so as to be rotatable about the second conductor ends 231b relative to the corresponding conductor rails 5, in this case the first conductor ends 231a can be pre-tensioned against the contacts 13 of a DIN rail device module 1 by means of the spring forces of the contact spring elements 16, 26. The conductor elements 23 can alternatively be designed in terms of their position and orientation direction of the conductor ends 231b on the conductor rail 5 such that a feed-in of the DIN rail device module 1 (shown in Fig. 24A) from below as well as from above. In particular, identically designed conductor rails 5 can be used for both the embodiment in Fig. 1A, Fig. 1B (power supply from above) as well as for the version in Fig. 30 (power supply from below) can be used; for the version in Fig. 30, the conductor rails 5 only have to be the other way round (compared to the embodiment in Fig. 1A, Fig. 1B) are inserted into the conductor insertion tracks 31. It should be noted that in alternative embodiments, the output terminals 9 can also be arranged in the opposite direction (i.e., on the first side of the DIN rail device modules 1 instead of on the second side of the DIN rail device modules 1 or on the lower side of the device carrier modules 3 instead of on the upper side of the device carrier modules 3). The arrangement (top or bottom) of the input terminals 8 can be adapted to the arrangement (top or bottom) of the output terminals 9 and / or to the number of device carrier modules 3 in the transverse direction in order to achieve the desired switching arrangement of the distributor. Since the conductor rails 5 do not have to be replaced for this purpose, but only have to be inserted into the conductor insertion tracks 31 in the appropriate orientation, flexibility and user-friendliness are further increased.

[0071] Fig. 25A shows an embodiment of a conductor rail 5 and conductor elements 23 attached thereto. Fig. 25B shows the enlarged section V from Fig. 25A. The conductor rail 5 from Fig. 25A and Fig. 25B has a greater thickness than the conductor rail 5 made of Fig. 24A and Fig. 24B. The conductor elements 23 in Fig. 25A and Fig. 25B are, however, identical to the conductor elements 23 in Fig. 24A and Fig. 24B trained.

[0072] Fig. 26A-C show three different embodiments of the conductor rail 5. The conductor rails 5 each have a fastening section 53 for fastening the conductor rail 5 to a corresponding conductor insertion track 31 of the device carrier module 3, as well as a contact section 54 for contacting the second conductor end 231b of a corresponding conductor element 23. The contact section 54 has, in particular, the notches 51 to which the second conductor ends 231b of the conductor elements 23 can be fastened. The three conductor rails 5 in Fig. 26A-C each have different thicknesses, with the conductor rail 5 in Fig. 26A the smallest thickness and the conductor rail 5 in Fig. 26C has the highest thickness. Nevertheless, the three conductor rails 5 can be used with identical device carrier modules 3 and with identical conductor elements 23, because for each conductor rail 5, a bottom side of the fastening section 53, with which the respective conductor rail 5 is fastened to the conductor insertion track 31, and a top side of the contact section 54, to which the corresponding conductor element 23 is fastened, have the same predetermined distance from each other. In the conductor rail 5 in Fig. 26C, this predetermined distance is equal to the thickness of the conductor rail 5.

[0073] Fig. 27A shows a perspective view of a DIN rail mounted device module 1, more specifically a fuse switching device module 1a. Fig. 27B shows a top view of the DIN rail device module 1 from Fig. 27A. Fig. Figure 27C shows a cross-sectional view along RR in Fig. 27B. In this embodiment, the DIN rail device module 1, 1a has four first contacts 13a and four second contacts 13b, each designed to contact the neutral conductor N and the three outer conductors L1, L2, L3. In particular, the first contacts 13a and the second contacts 13b are plate-shaped. Furthermore, the DIN rail device module 1 comprises guide elements 19 for engaging in grooves 29 or for contacting edges 29 of a connecting module 2 and for moving the DIN rail device module 1 relative to the connecting module 2 along the insertion direction. Fig. 27A also shows the first coding slots 15a, which are arranged on the first side of the DIN rail device module 1, and the second coding slots 15b, which are arranged on the second side of the DIN rail device module 1. When the DIN rail device module 1 is in the operating position, the coding slots 15a, 15b extend along the insertion direction. The first coding slots 15a and the second coding slots 15b of the fuse switch module 1, 1a are arranged diagonally relative to each other, so that the fuse switch module 1, 1a can only be inserted onto the left device carrier module 3 in Fig. 5C, but not on the central device carrier module 3 or the right device carrier module 3.

[0074] Fig. 27D shows a perspective view of a DIN rail mounted device module 1, more specifically of an RCD module 1b. Fig. 27E shows a perspective view of a DIN rail mounted device module 1, more specifically a circuit breaker protection device module 1c. Fig. Figure 27F shows a perspective view of another DIN rail device module 1d. The DIN rail device modules 1b, 1c, 1d from Fig. 27D to 27E each have similar features to the fuse switching device module 1a from Fig. 27A to 27C. However, in this embodiment, the circuit breaker protection module 1c has only one first contact 13a and one second contact 13b, each for contacting one of the three outer conductors L1, L2, L3 (i.e., it is a single-pole DIN rail-mounted device module 1c), and the further DIN rail-mounted device module 1d has three first contacts 13a and three second contacts 13b for contacting the three outer conductors L1, L2, L3 (i.e., it is a three-pole DIN rail-mounted device module 1d). The first coding slots 15a and the second coding slots 15b of the residual current device module 1b are arranged relative to one another in the longitudinal direction, so that the residual current device module 1b can only be connected to the central device carrier module 3 in Fig. 5C, but not on the left device carrier module 3 or the right device carrier module 3. The first coding slots 15a and the second coding slots 15b of the circuit breaker protection module 1c and the further DIN rail mounted device module 1d are arranged relative to each other in an opposite diagonal direction, so that the circuit breaker protection module 1c and the further DIN rail mounted device module 1d can only be plugged onto the right device carrier module 3 in Fig. 5C, but not on the left device carrier module 3 or the central device carrier module 3. In Fig. 27F also shows rectangular recesses of the DIN rail device module 1d, into which the coding elements 361 positively engage when the DIN rail device module 1d is in the operating position in order to prevent incorrect insertion of the DIN rail device modules 1, as described above.

[0075] Fig. 28 shows a perspective view of one embodiment of a modular DIN rail device system and one embodiment of a modular mounting panel system. Fig. Figure 29A shows a plan view of the modular DIN rail device system and the modular mounting panel system of Fig. 28. Fig. Figure 29B shows a cross-sectional view along OO in Fig. 29A. Fig. 29C shows the enlarged section P from Fig. 29B.

[0076] In this embodiment, two device carrier modules 3 are fastened to each other in the longitudinal direction via the corresponding longitudinal connecting elements 37a, 37b. In particular, the Fig. 29A top left arranged device carrier module 3 and the Fig. 29A, the further device carrier module 3 arranged at the bottom left is fastened to one another in the longitudinal direction such that the conductor insertion tracks 31 of the device carrier module 3 are extended or continued in the longitudinal direction by the conductor insertion tracks 31 of the further device carrier module 3. Thus, the conductor rails 5 arranged in the conductor insertion tracks 31 of the device carrier module 3 and the conductor rails 5 arranged in the conductor insertion tracks 31 of the further device carrier module 3 can be fastened to one another and brought into contact in order to obtain conductor rails 5 extended in the longitudinal direction. Thus, only a power supply via the clamping screws 8 of the Fig. 29A top left arranged device carrier module 3 is required, while the clamping screws 8 of the Fig. 29A, the bottom left-hand side of the device carrier module 3 are used to fasten and / or connect the conductor rails 5 in the device carrier module 3 with the conductor rails 5 in the further device carrier module 3. This embodiment of the mounting panel system can also be fastened to six parallel top-hat rails 7. It should be noted that one and the same connection of a device carrier module 3 or one and the same clamping screws 8 can thus be used for the power supply (as in the case of the device carrier module 3 shown in Fig. 29A top left arranged device carrier module 3) or for connecting another device carrier module 3 (as in the Fig. 29A, located at the bottom left, can be used with the device carrier module 3). This allows for individual and flexible installation, increasing user-friendliness depending on the desired application.

[0077] Fig. Figure 30 shows a perspective view of an embodiment of a modular DIN rail device system and an embodiment of a modular mounting panel system. In this embodiment, the power is supplied to the conductor rails 5 by a power feed block, which is mounted on a lower portion of the left device carrier module 3 (in Fig. 30 bottom left), i.e. at an opposite section compared to the embodiment described above (cf. Fig. 1A, Fig. 1B).

[0078] Fig. 31A shows a cross-sectional view of one embodiment of a modular DIN rail device system and one embodiment of a modular mounting panel system. Fig. 31B shows the enlarged section Q from Fig. 31A. In this embodiment, the DIN rail device module 1 (instead of the connection module 2 in the Fig. 6A and Fig. 6B) first contact spring elements 16a which are configured so that when the DIN rail device module 1 is in the operating position (as shown in Fig. 31A, Fig. 31B), the first contacts 13a of the DIN rail device module 1 and the first conductor ends 231a of the conductor elements 23 of the Fig. 31B right connection module 2, 2a are pre-tensioned against each other by means of spring forces of the first contact spring elements 16a. In this embodiment, the first contact spring elements 16a are fastened on the one hand to the DIN rail device housing 11 and on the other hand to the first contacts 13a of the DIN rail device module 1. The spring forces of the first contact spring elements 16a are perpendicular to the insertion direction (ie they run horizontally in Fig. 31A, B). The same applies to the second contact spring elements 16b and the second contacts 13b of the DIN rail device module 1 as well as the Fig. 31B left connection module 2, 2b.

[0079] Fig. Figure 32 shows a cross-sectional view of an embodiment of a modular DIN rail device system. In this embodiment, the DIN rail device module 1 comprises the contact spring elements 16, and the spring forces of the contact spring elements 16 are perpendicular to the insertion direction (ie, they run horizontally in Fig. 32).

[0080] Fig. Figure 33 shows a cross-sectional view of an embodiment of a modular DIN rail device system. In this embodiment, the connection module 2 or the device carrier module 3 comprises the contact spring elements 26, and the spring forces of the contact spring elements 26 run parallel to the insertion direction (ie, they run vertically in Fig. 33). The contact spring elements 26 are fastened on the one hand to the connection housing 21 or to the device carrier module 3 and on the other hand to the conductor ends 231 of the conductor elements 23 of the connection module 2. Alternatively, the DIN rail device module 1 can also comprise the contact spring elements 16 and the spring forces of the contact spring elements 16 can run parallel to the insertion direction; in this case, the contact spring elements 16 can be fastened on the one hand to the DIN rail device housing 11 and on the other hand to the contacts 13 of the DIN rail device module 1. This means that the springing can take place in the device carrier module 3 as in Fig. 33 or vice versa from the DIN rail mounted device module 1. It should be noted that in this embodiment the DIN rail mounted device module 1 is fixed relative to the connection module 2 by a snap connection, so that there is a balance of forces when the DIN rail mounted device module 1 is in the operating position.

[0081] Fig. Figure 34 shows a perspective view of an embodiment of a modular DIN rail device system.
