[0004] Description

[0005] Technical field

[0006] The invention relates to a conductor carrier for the electronic supply of an electronic device, a carrying device for attaching the electronic device and a system

[0007] background

[0008] From WO 2022 / 188955 Al, a support device, preferably implemented as a shelf rail, for the mechanical fastening of an electronic device, particularly preferably for fastening an electronic display unit, is known. The support device has a first boundary wall, in particular a reference or...A positioning-plane defining reference wall on which, or adjacent to which, the electronic device, in particular with its rear wall, can be positioned on the support device, and a second boundary wall oriented at an angle to the first boundary wall, wherein the first boundary wall and the second boundary wall, in particular only on two sides, define a receiving area for receiving the electronic device, and a conductor carrier that carries conductor tracks for the electronic supply of the device, wherein the conductor carrier projects into the receiving area from the second boundary wall at a distance from the first boundary wall, in particular parallel to the first boundary wall. According to a preferred embodiment, the conductor carrier is inserted in a T-shaped receiving shaft.To position the cable carrier within the support device, the cable carrier is inserted into the receiving shaft at the end of the support device and pushed along its length into the receiving shaft. This insertion process along the receiving shaft has proven to be cumbersome, as considerable frictional resistance must be overcome. Furthermore, jamming can occur, which slows down the workflow. The support device is typically installed in commercial or similar locations to provide product and / or pricing information. This information is displayed on electronic devices. Together with a power supply unit and the electronic device, the support device forms a system. A large number of these support devices are usually installed.Therefore, there is a desire for a system that is easy and quick to install, in order to mount as many electronic devices as possible in the business environment with minimal time expenditure. Thus, there remains a need to reduce the installation time and / or the manufacturing time of the system or the mounting device.

[0009] The invention therefore aims to provide a conductor carrier, a support device and a system that enable simple and rapid operational readiness of the system.

[0010] Summary of the invention

[0011] This problem is solved by a conductor carrier according to claim 1. The subject matter of the invention is therefore a conductor carrier for the electronic supply of an electronic device, wherein the conductor carrier has conductor tracks for the electronic supply of the electronic device, and wherein the conductor carrier has a connecting device for connecting the conductor carrier to a support device, preferably implemented as a shelf rail, wherein the support device for the mechanical fastening of the electronic device is preferably designed for supporting the electronic device alone, characterized in that the connecting device for connecting the conductor carrier is designed by means of a snap connection.

[0012] This problem is further solved by a support device according to claim 18. The invention therefore relates to a support device, preferably implemented as a shelf rail, for the mechanical fastening of an electronic device, particularly preferably for fastening an electronic display unit, wherein the support device has a support-connection device for connecting the support device to a conductor carrier, wherein the conductor carrier has conductor tracks and is designed for electronically supplying the electronic device, characterized in that the support-connection device is designed for connecting the support device by means of a snap connection.

[0013] This problem is further solved by a system according to claim 34. The invention therefore relates to a system for supplying power to an electronic device, wherein the system comprises a carrying device and a cable carrier according to the invention.

[0014] The measures according to the invention offer the advantage of providing a system that can be installed quickly and easily. Unlike the method proposed in WO 2022 / 188955 Al, the cable carrier does not need to be laboriously pushed into the receiving shaft from the end. Instead, the cable carrier can simply be connected to the support device using the snap connection. This allows many cable carriers to be connected to support devices in a short time. This can be done during the manufacturing of the support device, so that the support device can be delivered with the cable carrier already installed. This reduces manufacturing time. However, because the snap connection allows for easy installation, the cable carrier can also be offered and provided separately from the support device or in an unconnected state. Thus, for example, a business operator, e.g.An operator of a retail business can simply attach the cable carrier to the support device himself during the installation of the support device.

[0015] Further, particularly advantageous embodiments and developments of the invention will result from the dependent claims and the following description.

[0016] As mentioned, the carrying device is preferably designed solely for supporting the electronic device. The carrying device is therefore preferably designed such that it can support the electronic device independently of the presence of the conductor carrier. The conductor carrier can thus be designed to make contact with the electronic device via the conductor tracks without mechanically supporting it. The conductor carrier is therefore preferably free of structures for supporting the electronic device or parts thereof.

[0017] In general, the carrying device may be designed differently from WO 2022 / 188955 Al. According to a preferred embodiment, the carrying device, unless otherwise defined, is designed in accordance with WO 2022 / 188955 Al, which is incorporated by reference.

[0018] As discussed at the outset, it has proven advantageous that the support device, preferably implemented as a shelf rail, for the mechanical fastening of an electronic device, particularly preferably for the fastening of an electronic display unit, has a first boundary wall, in particular a reference wall defining a reference or positioning plane, on or adjacent to which the electronic device, in particular with its back wall, can be positioned on the support device, and has a second boundary wall oriented at an angle to the first boundary wall, wherein the first boundary wall and the second boundary wall, in particular only on two sides, define a receiving area for receiving the electronic device.

[0019] According to one aspect of the invention, the system comprises a supply unit, wherein the supply unit is designed such that it can be coupled to a side or end section of the support device, which side or end section is designed or provided for receiving the supply unit, wherein the supply unit is designed to transmit information signals and / or information data and / or a power supply to the conductor tracks of the conductor carrier. Thus, a system is provided which is generally easy and quick to assemble.

[0020] The supply facility is preferably designed in accordance with WO 2022 / 188955 Al, which is incorporated by reference.

[0021] The system can be configured to automatically determine the position of at least one electronic device (or shelf rail device) attached to the support device (designed as a shelf rail), as disclosed in WO 2022 / 189314, which is incorporated by reference. The system preferably forms a bus system, in particular a bus system according to WO 2022 / 188956, which is incorporated by reference.

[0022] According to one aspect of the invention, the system further comprises the electronic device.

[0023] Examples of electronic devices include, but are not limited to, sensor units or sensors such as motion sensors, temperature sensors, light sensors and cameras; input devices such as buttons, touch sensors, touch screens; output devices such as lights, speakers, printers, e.g. thermal printers; and electronic display units, such as those implemented using liquid crystal display (LCD) screens, organic light emitting diode (OLED) screens, etc., or e-paper displays or electrophoretic displays.

[0024] Preferably, the electronic device is designed as an electronic price label, known under the electronic name Electronic Shelf Label, or ESL for short.

[0025] The system can also incorporate different electronic devices. For example, the carrying device can support an ESL and a camera.

[0026] According to one aspect of the invention, the system preferably includes an energy storage unit, in particular designed as a battery unit. This further simplifies the installation of the system, since no cables, for example from a wall socket and / or a power supply, need to be laid to the system components.

[0027] The energy storage unit can be designed according to WO 2022 / 188955 Al. Particularly preferred is the energy storage unit designed according to EP23154358.8, which is incorporated by reference, where the energy storage device is referred to as an energy storage device. The energy storage device is therefore preferably designed for the electrical supply of a power supply unit located at least partially on the rear of the support device or carrier rail, which is intended for the electrical supply of at least one electronic device or electronic apparatus that can be attached to the front of the carrier rail. The energy storage device has a first coupling device designed for the direct, i.e., cable-free, electrical and mechanical coupling of the energy storage device to the power supply unit.

[0028] In general, it has proven advantageous for the cable support to be designed as a cable support plate. Using a plate shape allows for a space-saving yet stable design of the cable support. This enables the provision of a compact support device which, together with the cable support, can securely hold the electronic devices and supply them with power and information.

[0029] Furthermore, it has proven advantageous for the conductor carrier to comprise an electrically insulating material, in particular an electrically insulating polymer, and for the conductor tracks to be partially embedded in the insulating material. This allows for simple and rapid production of the conductor carrier. For example, the conductor carrier can be easily produced by extrusion, with the conductor tracks being embedded in the insulating material during the extrusion process.

[0030] The conductive pathways can, for example, have a round, triangular, or rectangular cross-section. A wire, for instance, can be used as a conductive pathway.

[0031] The conductor track, which can also be referred to as the conductor structure, can also be formed by a conductor strip or a conductor foil. It has proven particularly advantageous for the cross-sectional shape of the conductor strip or foil to be arc-shaped, whereby, viewed along the cross-section, the conductor strip or foil is partially connected to the conductor carrier and, in other areas, freely accessible from outside the conductor carrier to allow for contact for the transmission of power and / or information.

[0032] A conductor carrier with such a conductive foil or conductor strip as a conductor track is disclosed in PCT / EP2023 / 080665, and this application is hereby incorporated by reference. In PCT / EP2023 / 080665, the conductor carrier is referred to as a device. According to a preferred embodiment, the conductor carrier thus comprises, on the one hand, the connection device for connecting the conductor carrier by means of a snap connection and, on the other hand, the conductor tracks designed as a conductor strip according to PCT / EP2023 / 080665. This allows for the cost-effective provision of an easy-to-install conductor carrier, making the entire system more affordable.

[0033] According to a further aspect of the invention, it has proven advantageous for the connecting device to extend over at least a portion of the longitudinal extent of the conductor carrier, in particular over at least 25% of the longitudinal extent, preferably over at least 50% of the longitudinal extent, more preferably over at least 75% of the longitudinal extent, and most preferably over the entire longitudinal extent of the conductor carrier. The longitudinal extent of the conductor carrier is here defined as its longest dimension. Preferably, the conductor carrier has a vertical extent and a horizontal extent, which define a cross-sectional area normal to the longitudinal extent. The conductor carrier is particularly preferably defined to a large extent by an extrusion of this base area along the longitudinal extent.

[0034] The conductor tracks are preferably located on one side, and in particular exclusively on one side, of the conductor carrier. This allows the electronic device to press against the conductor tracks and make full contact without loosening other conductor tracks, since they are all located on the same side of the conductor carrier. This ensures a reliable power supply to the electronic devices.

[0035] Preferably, the conductor tracks extend along the longitudinal axis of the conductor carrier. This allows for flexible arrangement of the electronic device along the conductor carrier, because the conductor tracks are available along its entire length. It also makes it easy to supply multiple electronic devices through a single conductor carrier.

[0036] Furthermore, it has proven advantageous for the support-connecting device to extend over at least a portion of the longitudinal extent of the support device, in particular over at least 25% of the longitudinal extent, preferably over at least 50% of the support device, more preferably over at least 75% of the longitudinal extent, and most preferably over the entire longitudinal extent of the support device. The longitudinal extent of the support device is here defined as its longest dimension. Preferably, the support device has a vertical extent and a horizontal extent, which define a cross-sectional area normal to the longitudinal extent. The support device is most preferably defined to a large extent by an extrusion of this base area along the longitudinal extent.

[0037] The connecting device, which extends over at least part of the longitudinal extent of the conductor carrier, and the supporting connecting device, which extends over at least part of the longitudinal extent of the supporting device, offer the advantage that a particularly stable and at the same time easy-to-connect coupling between the two components can be provided, because a large contact area is thus provided.

[0038] Furthermore, the conductor carrier and / or the support device can be manufactured easily and inexpensively using, for example, extrusion or pultrusion, so that the connecting device or the support-connecting device is created directly in the extrusion or pultrusion process.

[0039] Furthermore, it has proven advantageous that the connecting device of the conductor carrier is designed to enter into a snap connection with the support device by means of a pivoting movement about an axis parallel to the longitudinal extent of the conductor carrier and / or by means of a bending about an axis parallel to the longitudinal extent of the conductor carrier.

[0040] Accordingly, the support-connection device is preferably designed to enter into a snap connection with the conductor carrier by means of a pivoting movement about an axis parallel to the longitudinal extent of the conductor carrier and / or by means of a bending about an axis parallel to the longitudinal extent of the support device.

[0041] During connection, part of the connecting device is moved around the support-connecting device, and / or part of the support-connecting device is moved around part of the connecting device. This preferably occurs around an axis parallel to the longitudinal extent of the cable carrier or the support device. This allows for a large gripping area, which in turn leads to a stable hold.

[0042] In principle, the carrying-connecting device of the carrying device can be designed to grip or snap around the connecting device of the conductor carrier, and the connecting device of the conductor carrier can be designed to be gripped or snapped around by the carrying-connecting device of the carrying device.

[0043] Preferably, the connecting device of the conductor carrier is designed to grip or snap around the carrying-connecting device of the carrying device, and the carrying-connecting device of the carrying device is preferably designed to be gripped or snapped around by the connecting device of the conductor carrier.

[0044] The following description for the preferred embodiment, in which the connecting device of the conductor carrier encompasses the support-connecting device of the support device, can, however, also be adapted by a person skilled in the art in reverse, i.e., so that the support-connecting device of the support device encompasses the connecting device of the conductor carrier.

[0045] A double snap connection can also be used, wherein the connecting device of the conductor carrier can be designed to grip or snap around the carrying connection device of the carrying device, and wherein the carrying connection device of the carrying device can be designed to grip the connecting device of the conductor carrier.

[0046] Multiple connecting devices or support-connecting devices can also be arranged side by side. The adjacent connecting devices or support-connecting devices can be identical, e.g., both snap-on or both snap-on, or different, e.g., one snap-on and one snap-on.

[0047] According to the preferred embodiment, it has therefore proven advantageous that the connecting device is designed to grip the support device, in particular a support-connecting device of the support device, preferably a snap-fit ​​connecting spring of the support-connecting device of the support device. This has the advantage that both the support device and the cable carrier can have a simple shape to manufacture. For example, both parts can be easily produced by continuous casting or extrusion. In other words, the complexity of the cross-section of the support device is reduced by designing the cable carrier to grip. However, because the cable carrier has few other requirements regarding its shape (only the conductor tracks need to be in the correct position), the complexity of the cross-section of the cable carrier is not significantly increased by this measure.This makes both components easier to manufacture and less prone to errors.

[0048] The connecting device of the conductor carrier preferably snaps around the support connecting device of the support structure and holds it in place. The support connecting device is preferably designed as a snap-fit ​​spring or has a snap-fit ​​spring. The snap-fit ​​spring is elongated and preferably extends along the longitudinal axis of the conductor carrier. The connecting device preferably has a snap-fit ​​groove for receiving the snap-fit ​​spring. In the snapped-in state, the snap-fit ​​spring is located in the snap-fit ​​groove and is held by it.

[0049] Accordingly, the carrying-connecting device of the carrying device is preferably designed to be gripped by a connecting device of the conductor carrier.

[0050] The carrying device's connecting element preferably has a snap-fit ​​spring or is designed as a snap-fit ​​spring. A snap-fit ​​spring is a spring in the sense of a tongue-and-groove connection, which also has a shape that allows it to snap into place, so that in the snapped-in state, a positive locking mechanism prevents the snapped-in parts from separating.

[0051] To provide this positive locking, it has proven advantageous for the carrying-connecting device to have a waist.

[0052] Preferably, the snap-fit ​​spring has a tapered cross-section, particularly in the cross-section normal to the longitudinal extent of the support device. The tapered area of ​​the snap-fit ​​spring can be gripped by the gripping elements of the cable carrier. This provides a stable connection between the support device and the cable carrier. The gripping elements can be held securely within the tapered section.

[0053] The waist is preferably designed without steps. This allows the gripping elements to slide continuously over the carrying / connecting device without any jumping. The release / holding angle of the snap-connection spring is preferably not 90°. Preferably, the release / holding angle of the snap-connection spring is less than 90°.

[0054] The gripping elements are preferably connected to each other, preferably by a material bond, and in particular made of a single material. This allows for particularly simple manufacturing of the conductor carrier.

[0055] Preferably, the connecting device of the conductor carrier has gripping elements that provide the snap-fit ​​groove for receiving the support device, in particular the support-connecting device of the support device. A snap-fit ​​groove is a groove in the sense of a tongue-and-groove connection, which simultaneously has a shape that allows it to snap into place, so that in the snapped-in state, a positive locking mechanism prevents the snapped-in parts from separating.

[0056] The snap-fit ​​spring can, for example, be solid, so that the snap-fit ​​groove deforms when connected or snapped into place, while the snap-fit ​​spring remains largely undeformed. Alternatively, the snap-fit ​​spring can have a gap and / or be segmented and / or slotted, so that it deforms, especially compresses, when connected. The snap-fit ​​groove can be rigid relative to the snap-fit ​​spring, meaning that essentially only the snap-fit ​​spring deforms when connected. However, the snap-fit ​​groove and the snap-fit ​​spring can also be designed so that both deform when connected.

[0057] Preferably, at least the snap-fit ​​groove is designed in such a way that it, or the gripping elements, deform or deform during connection.

[0058] Furthermore, the gripping elements are preferably designed in such a way that they have an Omega profile in the cross-section of the conductor carrier in its longitudinal extension, i.e., are shaped like a “Q” (capital letter of the Greek letter Omega).

[0059] It has proven advantageous that the connecting device of the conductor carrier has a bending groove that is distinct from the snap-in connection groove, wherein the gripping elements are bendable around the bending groove.

[0060] The bending groove allows for simple and defined deformation of the connecting device. This simplifies and speeds up the installation and assembly of the cable carrier with the support device. It also reduces the risk of damage during assembly because the stresses occurring in the material of the cable carrier and the support device are reduced and / or distributed.

[0061] Preferably, the snap-fit ​​groove transitions into the bending groove. Particularly preferably, the bending groove forms a groove within the snap-fit ​​groove. The bending groove preferably has a smaller average radius of curvature than the snap-fit ​​groove.

[0062] It has proven advantageous for the bending groove to extend over the longitudinal extent of the conductor carrier, in particular over at least 25%, preferably over 50%, preferably over 75%, and most preferably over the entire longitudinal extent of the conductor carrier.

[0063] According to one aspect of the invention, the support-connecting device of the support assembly has a rounded and / or pointed end region in cross-section, particularly in cross-section normal to the longitudinal extent of the support assembly. This end region is designed to spread the gripping elements of the cable carrier. Thus, the cable carrier can be easily pressed against the end region of the support-connecting device with its gripping elements, causing the gripping elements to spread and engage the support-connecting device. This prevents, for example, misalignment when joining the cable carrier and the support assembly, thereby further simplifying the installation process and preventing damage.

[0064] According to a further aspect of the invention, the support-connecting device of the support device is designed as a snap-fit ​​spring and has an asymmetrical cross-section, particularly in the cross-section normal to the longitudinal extent of the support device. Accordingly, the snap-fit ​​groove of the conductor carrier is preferably designed for planar contact with the asymmetrical snap-fit ​​spring via its side surfaces. On the one hand, this provides a stable connection between the support device and the conductor carrier because they are connected over a large area. On the other hand, the asymmetrical cross-section allows the support device and the conductor carrier to be easily separated from each other by tilting the two parts relative to one another.

[0065] It has proven advantageous for the connecting device of the conductor carrier to have an opening, in particular an opening between two gripping elements. The opening is designed to receive the support device, in particular the support-connecting device of the support device. The opening is preferably inclined in cross-section perpendicular to the longitudinal extent of the conductor carrier, in particular at an angle between 15° and 45°, preferably 30°, to a transverse extent of the conductor carrier and / or a transverse axis of the conductor carrier and / or inclined relative to a conductor track wall to which the conductor tracks are attached.

[0066] The conductor rail wall is a wall to which the conductor rails are attached. Generally, several conductor rail walls can be provided, e.g., on opposite sides of the conductor support. However, as mentioned, preferably all conductor rails are located on one side and, in particular, on a single conductor rail wall. The conductor support therefore preferably has exactly one conductor rail wall.

[0067] The opening thus connects the area surrounding the conductor carrier to the snap-fit ​​groove. In this context, "oblique" means that an arrow pointing from the center of the snap-fit ​​groove towards the center of the opening runs at an angle (other than 0°) to the transverse dimension of the conductor carrier and / or its transverse axis and / or the conductor track wall. This angle is preferably between 15° and 45°, particularly preferably 30°. The transverse dimension of the conductor carrier, its transverse axis, and the conductor track wall preferably run parallel to each other.

[0068] The angled opening ensures a stable hold when the cable carrier is connected to the support device because the opening is located laterally, preventing the support device from being easily pulled off, for example, along its transverse axis. At the same time, however, the cable carrier can be easily detached from the support device by additionally tilting it around its longitudinal axis.

[0069] Furthermore, it has proven advantageous that the connecting device has an asymmetrical cross-section perpendicular to the longitudinal axis of the cable carrier. This measure also results in a stable hold and simultaneously allows for easy release by means of a tilting motion. Due to the asymmetrical shape, one side is more easily detached than the other. Thus, the cable carrier can be easily removed by a movement that releases this more easily detached side. The asymmetrical shape therefore defines a removal direction and / or a removal movement that allows for easy removal. At the same time, the shape counteracts removal when the cable carrier is under load, in a different direction or movement. The hold between the cable carrier and the support device is thus improved.This is preferably used in conjunction with the slanted opening.

[0070] Furthermore, it has proven advantageous for the connecting device to have at least two, preferably exactly two, gripping elements, wherein at least one first gripping element is longer than a second gripping element. This results in one gripping element, usually the longer one, being more easily elastically deformed than the other. Simultaneously, this results in the gripping elements contacting the support device at different heights when connected. If the conductor carrier connected to the support device is tilted relative to the support device, this allows the longer first gripping element to pivot around the contact area of ​​the second gripping element with the support device. In this process, both gripping elements typically deform elastically, causing both gripping elements to detach from the support device.The geometry thus defines a path that the first gripping element follows as a result of a tilting movement to detach the cable carrier from the support device. This enables rapid uninstallation or dismantling of the cable carrier. Reassembly of the cable carrier with the support device is also accelerated by this measure, as a movement along this path in the opposite direction to the removal movement allows for particularly easy installation.

[0071] Furthermore, it has proven advantageous that the connecting device has a hook-shaped gripping element with a curved holding surface. This allows the cable carrier to be pulled off the support device, particularly during a tilting motion, without causing damage. On the one hand, the curved holding surfaces allow for easy sliding. On the other hand, the shape avoids mechanical stress concentrations in the material. The curved holding surfaces also increase the grip when connected, as a larger area contacts the support device compared to flat holding surfaces.

[0072] The holding surface is the area designed and configured to contact the support device or its connecting device when connected. The holding surface is therefore the area capable of absorbing holding forces. The holding force is the force acting on the snap-fit ​​connection device to hold it in place, as defined, for example, in guideline DVS 2242-1.

[0073] Furthermore, it has proven advantageous for the connecting device to include a gripping element, wherein the gripping element has a hook-shaped section. The hook-shaped section has a release / holding angle other than 90°, preferably a release / holding angle less than 90°, particularly preferably a release / holding angle between 60.0° and 87.5°, and especially preferably a release / holding angle between 75° and 85°, and in particular a release / holding angle of 80°. While a 90° holding angle provides a strong connection between the cable carrier and the support device, separating them is either impossible or results in extreme stress on the materials of the cable carrier and the support device because the geometry resists separation. In contrast, this measure allows for easy removal of the cable carrier from the support device without causing damage.At the same time, however, a sufficiently strong connection is provided to supply the electronic devices with power and / or information.

[0074] The release or holding angle corresponds to the holding angle according to guideline DVS 2242-1. However, the lever arm is preferably not straight or only straight in sections, in particular along a section in front of the hook-shaped section.

[0075] In this context, it has proven advantageous that the carrying device is designed to absorb the weight of the carried electronic device. The cable carrier is preferably designed such that it does not absorb any weight of the carried electronic device, or at least no component of the weight of the carried electronic device in the vertical direction. Thus, the connection device of the cable carrier and the carrying device's connection device can be designed so that they can be separated from each other with relatively little force. This allows the cable carrier to be easily detached from the carrying device. At the same time, many and / or heavy electronic devices can be carried without the cable carrier unintentionally detaching from the carrying device, since the weight of the electronic devices is not transmitted to the carrying device via the cable carrier.

[0076] The hook-shaped section preferably forms the end section of the gripping element. This allows for a compact design.

[0077] According to one aspect of the invention, it has proven advantageous for the connecting device to be shaped such that, in the state connected to the support device, rotational movements of the conductor carrier relative to the support device are prevented. Preferably, the connecting device is shaped at least such that, in the state connected to the support device, rotational movements of the conductor carrier relative to the support device are prevented without deformation of the connecting device. Accordingly, the support-connecting device is preferably shaped such that, in the state connected to the conductor carrier, rotational movements of the conductor carrier relative to the support device are prevented.

[0078] This allows the cable carrier and mounting bracket to be quickly connected without the need for any further measures to provide a stable hold for the electronic devices. The cable carrier and mounting bracket thus ensure a secure hold for the electronic device. The electronic device can therefore make contact with the conductor tracks via its spring contacts without causing the cable carrier to move in a way that could result in insufficient contact between the spring contact and the conductor track.

[0079] According to a further aspect of the invention, it has proven advantageous that the support-connection device is positioned such that, when connected to the conductor carrier, a receiving area for the electronic device is formed. This further simplifies installation and provides optimal positioning of the conductor tracks because the electronic device, in particular a part of the electronic device containing the spring contacts, can be positioned in the receiving area specifically provided for this purpose. Thus, the conductor carrier and the support device can, for example, form enclosing walls that encompass the device and hold it in position. The enclosing walls can therefore, on the one hand, provide a structure for mechanical coupling and / or define its position. On the other hand, the enclosing walls define the position of the conductor tracks.

[0080] Preferably, the support device has a first boundary wall, wherein the support-connecting device is positioned such that the receiving area is spanned between the boundary wall and the conductor carrier in the connected state. The boundary wall and the conductor carrier thus form enclosing walls, from which the aforementioned advantages arise.

[0081] Furthermore, it has proven advantageous that the support and connection device is positioned and designed such that, when connected, the conductor tracks of the cable carrier protrude into the receiving area. This provides particularly good protection for the cable carriers against environmental influences such as splashing water or contact. Thus, damage to the conductor tracks and the entire system is prevented. It has also proven advantageous that the support device has a first boundary wall, with the support and connection device positioned such that, when connected, the cable carrier is parallel to this boundary wall. This allows for particularly simple and therefore quick positioning of the electronic devices in the support device, as they only need to be slid in a straight line parallel to the boundary wall and the support device to the desired position.This prevents, for example, misidentification.

[0082] According to another aspect, it has proven advantageous that the support device has a second boundary wall, the second boundary wall being connected to the support connection device and the first boundary wall. Thus, the support device and the boundary walls enclose a supported electronic device on three sides in certain areas, thereby providing comprehensive protection against environmental influences.

[0083] Preferably, the second boundary wall extends over the entire longitudinal extent of the support device. This provides particularly good protection because the electronic device is thus partially enclosed at any position within the support device.

[0084] The first and / or second boundary wall is preferably designed in accordance with WO 2022 / 188955 Al.

[0085] In one respect, it has proven advantageous that the first boundary wall has recesses, particularly recesses arranged in a grid, designed for positive and / or force-fit coupling with fastening elements of an electronic device. The recesses are easy and inexpensive to manufacture. This allows for the provision of a simple-to-manufacture support structure, enabling quick and easy installation of the electronic devices. Thus, the entire system can be deployed rapidly.

[0086] The recesses are preferably designed according to WO 2022 / 188955 Al. The electronic device can thus be held in place by the recesses. The electronic device can thereby contact the conductor tracks of the conductor carrier without having to physically grip the electronic device itself. The electronic device can therefore be free of structures for mechanical gripping by the electronic device, in particular free of recesses and / or projections. The conductor carrier is therefore preferably free of recesses and / or projections.

[0087] It should be noted that the carrying device is designed for connection with the conductor carrier according to the invention.

[0088] The conductor carrier is accordingly designed for connection with the support device according to the invention.

[0089] Finally, it should be mentioned generally that the electronic entities discussed (the electronic device, the power supply unit, etc.) naturally contain electronics. These electronics can be discrete, integrated, or a combination of both. Microcomputers, microcontrollers, and application-specific integrated circuits (ASICs) may also be used, possibly in combination with analog or digital electronic peripherals. Many of the devices' functionalities are implemented—possibly in conjunction with hardware components—using software running on a processor within the electronics. Devices designed for radio communication typically include an antenna configuration for transmitting and receiving radio signals as part of a transceiver module.The electronic devices can also have an internal power supply, which can be implemented, for example, with a replaceable or rechargeable battery. Alternatively, the devices can be powered via a wired connection, either through an external power supply unit or via Power over LAN.

[0090] These and other aspects of the invention will become apparent from the figures discussed below.

[0099] Description of the exemplary implementations

[0100] Figure 1 shows a support device 1 realized as a shelf rail 1, as known from WO 2022 / 188955 Al, and an electronic device 20 compatible with the support device 1, exemplified as an electronic display unit 20, in a lateral view, wherein the shelf rail 1 can be seen in a section along a section surface adjacent to the display unit 20.

[0101] The shelf rail 1 has a first boundary wall 2 (reference wall 2), which is shown vertically in the figure.

[0102] At its upper end, the first boundary wall or reference wall 2 transitions into a second boundary wall 3. In this embodiment, the second boundary wall 3 and the reference wall 2 are made of steel as a single piece.

[0103] Between the reference wall 2 and the second boundary wall 3 there is a receiving area 4, bounded on two sides by these walls 2 and 3, for receiving the display unit 20.

[0104] On the side of the display unit 20, i.e., measured within the spatial area of ​​the recording area 4, an acute angle 8 of approximately 53° is formed between the reference wall 2 and the second boundary wall 3. The second boundary wall 3 has a receiving slot 7 in which a conductor carrier 5, designed as a conductor carrier plate, is inserted. The conductor carrier 5 is adapted to the shape of the receiving slot 7 on the side that is inserted into it, i.e., it is essentially T-shaped. The conductor carrier 5 can be moved within the receiving slot 7 perpendicular to the plane of Figure 1, either in or out of it, in order to insert or remove it.

[0105] The conductor carrier 5 carries three conductor tracks 6. The conductor tracks 6 are each made of a single-core copper wire 6 and are designed without an insulating layer. More than 50% of the cross-section of the wires 6, approximately two-thirds of the radial dimension, is embedded in the conductor carrier 5. The wire 6 closest to the second boundary wall 3 is the power supply line, the middle conductor track 6 is the signal supply line, and the conductor track 6 furthest from the second boundary wall 3 is the reference potential line. The wires 6 are arranged on the side of the conductor carrier 5 facing the reference wall 2.

[0106] The conductor support 5 and the reference wall 2 each have a first dimension (longitudinal extent) that represents the length measured out of or into the plane of the image, respectively, where in this embodiment both are the same size and, for example, approximately 1.5 m long. However, other lengths can also be provided for the shelf rail 1.

[0107] The conductor support 5 has a second dimension 9 (height), which represents the vertical extent of the conductor support 5 in Figure 1. Correspondingly, the reference wall 2 has a third dimension 10 (height), which indicates the vertical extent of the reference wall 2 in Figure 1. In this embodiment, the second dimension 9 of the conductor support 5 is approximately 40% of the third dimension 10 of the reference wall 2. For example, the second dimension 9 in this embodiment is approximately 3 cm.

[0108] In this embodiment, the conductor carrier 5 is manufactured from insulating polypropylene using an injection molding process, wherein the wires 6 were already embedded during the manufacturing process of the conductor carrier 5.

[0109] The second boundary wall 3 has a nose- or hook-shaped edge area 12 at its end, which, when the display unit 20 is inserted, prevents it from being moved away from the reference wall 2 in the normal direction relative to the reference wall 2.

[0110] The reference wall 2 has recesses 13 arranged in a grid, which serve to attach the display unit 20.

[0111] The boundary wall 2 has a structure of boundary wall ribs 56 and intervening boundary wall grooves 57 in an area spanned by the conductor carrier 5. This structure is designed to interact with a structure of housing ribs 54 and intervening housing grooves 55 of the housing 21 of the display unit 20 in order to establish a desired orientation of the electronic device 20 when the electronic device 20 is inserted into the support device 1 as intended.

[0112] The display unit 20 is positioned in Figure 1 so that it can be inserted into the shelf rail 1 from below in a straight-line movement parallel to the reference wall 2 in the direction of the second boundary wall 3.

[0113] The display unit 20 comprises a housing 21 with a rear panel 22. The rear panel 22 represents the part of the housing 21 that, as shown in Figure 2, is closest to the reference wall 2 when inserted into the shelf rail 1. Opposite the rear panel 22 is a front panel 23, which includes a screen 24. The front panel 23 has a step at its upper end, designed to receive the edge section 12 of the shelf rail 1. A side panel 25 forms the housing 21 between the front panel 23 and the rear panel 22. The side panel 25, which runs along the top of the display unit 20, has a cable carrier groove 26, the vertical walls of which run substantially parallel to the rear panel 22. The cable carrier groove 26 is designed to receive the cable carrier 5 and is dimensioned to accommodate it.

[0114] The housing 21 has openings on its rear side in the conductor carrier groove 26 through which contacts 27 protrude from the housing 21 into the conductor carrier groove 26. The contacts 27 are implemented by a group of metallic contact strips 27.

[0115] The display unit 20 has a mounting mechanism 32 which is designed in one piece and has two mounting hooks 33 and an associated knob 34. The mounting mechanism 32 is also in contact with a spring element 35 designed as a coil spring.

[0116] Figure 2 shows the electronic device 20 inserted into the shelf rail 1.

[0117] The conductor carrier 5 shown in Figures 1 and 2 can, as mentioned, be inserted laterally into the receiving shaft 7. However, this is time-consuming and can lead to damage to the conductor carrier 5 and / or the receiving shaft 7. These problems are overcome by a support device 100 according to the invention, as shown in Figure 3.

[0118] Figure 3 shows a carrying device 100 according to the invention, which carries a conductor carrier 500 according to the invention. The carrying device 100 and the conductor carrier 500 together form a system 1000 for supplying an electronic device 20. The carrying device 100 largely corresponds to that of Figures 1 and 2, but instead of the receiving shaft 7, it has a carrying-connecting device 70 for carrying the conductor carrier 500 or for connecting it to the conductor carrier 500. The carrying-connecting device 70 is designed as a snap-fit ​​connection spring, i.e., for forming a tongue-and-groove connection with a snap connection.

[0119] The support device 100 has a first shelf connector 512a for connecting the support device 100 to a shelf. This differs from a second shelf connector 512b as shown in Figures 1 and 2. It should be noted that the support device 100 of Figure 3 can also be equipped with the second shelf connector 512b. However, the first shelf connector 512a has spring arms extending away from the first boundary wall 2, which facilitates easier connection to the shelf. Furthermore, the first shelf connector 512a has shelf connector hooks that provide improved support.

[0120] The conductor carrier 500 is constructed largely like the conductor carrier 5 of Figures 1 and 2, but has a connecting device 501 for connecting the conductor carrier 500 to a support device 100, wherein the connecting device 501 is designed by means of a snap connection. The connecting device 501 extends over the entire longitudinal extent of the conductor carrier 501, i.e., in the direction normal to the cross-section shown in Figure 3. The connecting device 501 is designed to engage the support device 100, specifically the snap-connection spring of the support-connection device 70 of the support device 100.

[0121] The conductor carrier 500 is designed as a conductor carrier plate.

[0122] The conductor carrier is largely made of an electrically insulating material, specifically an electrically insulating polymer. The conductor tracks 6 are partially embedded in the insulating material.

[0123] The conductor tracks 6 extend along the longitudinal extent of the conductor carrier. In Figure 3, the conductor tracks 6 therefore run perpendicular to the image plane.

[0124] The conductor support 500 has a conductor rail wall 506 to which the conductor rails 6 are attached. Specifically, the conductor support 500 has a single conductor rail wall 506, so that all conductor rails 6 are located on one side, namely on the side of the conductor support 500 facing the receiving area 4.

[0125] The connecting device 501 has an asymmetrical cross-section perpendicular to the longitudinal extent of the conductor carrier 500 and comprises gripping elements 503, specifically a first gripping element 503a and a second gripping element 503b, wherein the first gripping element 503a is longer than the second gripping element 503b. The gripping elements 503 provide a snap-fit ​​groove 502 for receiving the support device 100, specifically the support-connecting device 70 of the support device 100. The snap-fit ​​groove 502 transitions into a bending groove 504. The bending groove 504 adjoins the cross-section of the snap-fit ​​groove 502 at the point where, without the bending groove 504, mechanical stress peaks would occur in the material upon deformation of the gripping elements 503. The rounded shape of the bending groove 504 and the smaller radius compared to the snap-fit ​​groove 502 prevent these mechanical stress peaks and ensure a defined stiffness.A defined distribution of the stiffness of the connecting device 501 is provided. This enables the gripping elements 503 to be moved relative to each other in a material-friendly manner, thus enabling a material-friendly and at the same time stable gripping of the carrying device.

[0126] The connecting device 501 has an opening 505 between the two gripping elements 503a and 503b. The opening 505 is designed to receive the connecting device 70 of the support device 100 and, in the cross-section shown here, is located perpendicular to the longitudinal extent of the conductor carrier 500, obliquely to a transverse extent of the conductor carrier 500 and to a transverse axis of the conductor carrier 500, and obliquely relative to the conductor track wall 506, to which the conductor tracks 6 are attached.

[0127] Figure 4 shows a detailed view of the conductor carrier 500 connected to the support device 100. As shown in Figure 4, the opening 505 is skewed in cross-section perpendicular to the longitudinal extent of the conductor carrier 500, at an angle, here designated as the opening position angle 507, between 15° and 45°, preferably 30°, to a transverse dimension of the conductor carrier 500, indicated by a dashed line 508. The opening position angle 507 is defined by the dashed line 508 and an arrow 509. The arrow 509 extends from the centroid of the opening shape, perpendicular to the longitudinal extent of the conductor carrier 500, through the center of the opening 505, i.e., through the center of the section between the gripping elements 503 in cross-section.

[0128] Both the first gripping element 503a and the second gripping element 503b of the connecting device 501 are each hook-shaped and have a curved holding surface. The holding surface is the surface that the carrying-connecting device 70 contacts for holding it or for stopping against it.

[0129] The first gripping element 503a and the second gripping element 503b each have a hook-shaped section 510, wherein the hook-shaped section has a release or holding angle 511 other than 90°.

[0130] The release or holding angle 511 is preferably less than 90°, particularly preferably between 60.0° and 87.5°, and especially preferably between 75° and 85°. In the specific embodiment, the release or holding angle 511 of the first gripping element 503a is approximately 80°.

[0131] The connecting device 501 is shaped such that, when connected to the support device 100, rotational movements of the conductor carrier 500 relative to the support device 100 are prevented. The conductor carrier 500 can therefore not swing freely about an axis parallel to its longitudinal extent. Only by applying a defined force can the connecting device 501 be (elastically) deformed and the conductor carrier 500 tilted away from the first boundary wall 2 of the support device and removed.

[0132] The carrying-connecting device 70, specifically the snap-connecting spring, of the carrying device 100 has a stepless waist 71 in cross-section normal to the longitudinal extent of the carrying device 100. The waist 72 separates a section 72 of the carrying-connecting device 70, which appears convex in cross-section, from the second boundary wall 3. The convex section 72 is adapted to the shape of the gripping elements 503.

[0133] The carrying-connecting device 70 has an end region 73 that is rounded in cross-section normal to the longitudinal extent of the carrying device 100.

[0134] The cable carrier 500 and the support device 100 can be quickly and securely connected using the aforementioned methods. To do this, the cable carrier 500 simply needs to be pressed against the support device 70 with the connecting device 501 facing it. The cable carrier 500 is designed to engage the snap connection with the support device 100 by means of a pivoting movement about an axis parallel to its longitudinal extent and / or by means of a bending movement about an axis parallel to its longitudinal extent. The gripping elements 503 thus deform elastically, so that the opening 505 enlarges and the support device 70, in particular the bulbous section 72, fits through the opening 505. The gripping elements 503 then snap shut, so that their hook-shaped sections 510 engage in the waist 71 of the support device 70.

[0135] The shape of the support-connection device 70 and the connection device 501 prevents rotational movement of the conductor carrier 500 relative to the support device 100. When the electronic device 20 is inserted (as described in Figures 1 and 2), it can make contact with the conductors without them shifting. This provides a mechanically stable connection. At the same time, the connection device 501 remains unaffected by the weight of the electronic device 20, as it is fully supported by the support device 100. For this purpose, the support device 100 has the recesses 13 and the nose- or hook-shaped edge region 12. The electronic device 20 engages in the recesses and is held by the nose- or hook-shaped edge region 12. The conductor carrier 500 is therefore free of any structures for supporting the electronic device 20.This provides a System 1000 which is particularly quick to install or set up and reliably supplies the electronic device.

[0136] Preferably, the system 1000 further comprises a supply device 40 for transmitting information signals and / or information data and / or a power supply to the conductor tracks 6 of the conductor carrier 500, as shown in Figures 5 and 6.

[0137] Figure 5 shows the system 1000 comprising the carrying device 100, the cable carrier 500 and the power supply unit 40. The system 1000 supplies two of the electronic devices 20.

[0138] Figure 6 shows the rear side of the system 1000 shown in Figure 5. The power supply unit 40 provides the electronic devices 20 with data and / or power according to WO 2022 / 188955 Al. It should be noted again that the figures described in detail above are only exemplary embodiments, which can be modified in various ways by a person skilled in the art without departing from the scope of the invention. For the sake of completeness, it should also be noted that the use of the indefinite articles "a" or "an" does not preclude the possibility that the features in question may be present multiple times.
