Description

[0001] The present invention relates to a cable guiding device and a pre-assembled cable harness with at least a first and a second such cable guiding device.

[0002] When installing electrical systems, such as photovoltaic systems, a large number of cables must be laid. Typically, the cables are routed to a suitable location in a cable duct or tied together with cable ties, possibly permanently. However, if a specific spatial arrangement of the cables must be observed, for example, if individual cables need to be routed out during the installation process, this can typically only be accomplished in a time-consuming and costly manner. Furthermore, such loose cable laying frequently leads to cable twisting, which is detrimental to cable traceability and also to the quality of the cable material.

[0003] However, this cannot usually be achieved satisfactorily, especially with a large number of cables, and cable assembly in the field always proves to be very time-consuming.

[0004] Based on this, the invention proposes a cable routing device having the features of claim 1 and a prefabricated cable harness having the features of claim 26. Advantageous further developments are the subject of the dependent claims.

[0005] The cable guide device according to the invention can be designed, for example, as a modular cable guide for parallel guiding of at least eight or twelve cables of a cable harness of a photovoltaic system.

[0006] The invention is an advantageous embodiment of a cable routing device in which a cable to be routed can be inserted into each of the guide channels. In this way, a spatial structuring of the guided cables can be achieved, which, for example, also enables appropriate labeling. Retention of the structure thus produced, even when force is applied to the cable to be guided, can be ensured by closing the guide channel using the closure element provided according to the invention. Fastening the closure element to the guide element by means of a snap lock enables particularly simple handling. In this way, spatially orderly, clear and traceable cable routing can be achieved even when a large number of cables are to be laid, for example in a multi-strand cable harness.In addition, there are regularly options for the fixed installation of such a cable routing device in the field, for example by means of screws, in particular self-tapping screws, or cable ties, for example on frames of photovoltaic systems.

[0007] The guide channels are open toward the insertion side of the guide element. The guide channels can suitably have a substantially round cross-section. The opening of the guide channels can, for example, be located in a tapered section of the (particularly round) cross-section. The width or diameter of the guide channels can be configured depending on the diameter of a cable to be guided. For example, the maximum width of the guide channels can be 4 mm to 10 mm, in particular 6 mm.

[0008] It is conceivable that the cable routing device is designed such that several, for example, three or four, closure elements can be attached simultaneously, in particular next to one another, to a single guide element. Accordingly, the respective components of the interacting snap-in closure can then be designed for releasable attachment to one another. For example, the guide element comprises three or four times the number of components of the snap-in closure compared to the number of components comprised by the closure element.

[0009] In one embodiment, the guide channels are each open on one side perpendicular to the insertion side. In addition, movement of a cable to be guided toward the side perpendicular to the insertion side can be limited by the closure element when fastened to the guide element. This allows for particularly easy insertion of a cable into one of the guide channels, while still providing sufficiently secure retention of the inserted cable in the channel.

[0010] For example, the snap fastener can be designed as a rotary snap fastener. The components of the snap fastener can be formed on the closure element side as two lugs formed on a shaft, movable through corresponding openings in the guide element, which, after passing through the openings, can be brought into components of the snap fastener on the guide element side, formed as corresponding undercuts, by rotation of the closure element relative to the guide element. A snap fastener designed in this way corresponds to a bayonet lock. In this way, a particularly secure yet easily detachable attachment of the closure element and the guide element to one another can be achieved.

[0011] The lugs can be moved through the openings in two orientations of the closure element relative to the guide element, which allows for simple design of such a rotary snap-in closure. This can be further simplified by allowing the lugs to be moved through the openings only in a first and a second orientation of the closure element relative to the guide element. The second orientation can correspond to a rotation of the closure element by 180 degrees relative to the first orientation.

[0012] To properly secure the closure element to the guide element, the lugs can be moved into the undercuts by rotating the closure element 90 degrees relative to the guide element. This allows for sufficiently secure attachment of the closure element to the guide element.

[0013] The closure element can be rotationally symmetrical about a vertical axis. Alternatively or additionally, the closure element can have a handle.

[0014] As already indicated, the width of the guide channels at the insertion-side opening can be smaller than the width inside the guide channel. In this case, the width of the respective guide channel perpendicular to a width of the guide element is greater than the width of the opening on the insertion side. In other words, the extent of the respective guide channel at the insertion-side opening is then smaller than the maximum extent of the guide channel perpendicular to the width of the guide element, i.e. the maximum extent of the cross-section. For example, in the case of a guide channel with an essentially round cross-section, the width of the guide channel is then smaller than the diameter of the cross-section. The guide element can be formed from a material that offers sufficient flexibility for this purpose.

[0015] Particularly in cases where the diameter of the cable to be routed is larger than the width of the guide channel opening, the cable can be firmly inserted into the guide channel. This allows the cable to be quickly and easily removed from the guide channel without the need for additional tools, at least during the installation of a guide device or during the laying of cables to be routed, thus further simplifying the installation process.

[0016] At least one retaining clip, in particular two retaining clips, can be arranged at the insertion-side opening on at least one, in particular on at least two of the guide channels, for releasably securing the cable to be guided in the respective guide channel. In this case, the retaining clip can additionally be configured such that it limits movement of a cable to be guided toward the insertion side and allows movement of the cable to be guided to a side perpendicular to the insertion side, in particular to the side toward which the guide channels are open, beyond the extent of the retaining clip.In this way, in particular when the guide channel is designed to be open on one side perpendicular to the insertion side, at least during the installation of a guide device or during the laying of cables to be guided, it is possible to quickly and detachably hold the cable within the guide channel without additional tools, which can further simplify the laying.

[0017] The guide element can have four, in particular eight or twelve, guide channels. Such a configuration is particularly suitable for a wide range of applications, such as the installation of cables during the installation of a photovoltaic system. This allows a sufficient number of guide channels to be provided while still keeping the dimensions of the guide device small enough for easy handling.

[0018] Additionally, two guide channels can be arranged directly adjacent to each other. This allows for a spatially close arrangement of two cables to be routed, which is advantageous, for example, when laying cables of different polarity. This allows, for example, when laying a cable harness for a photovoltaic system, the desired spatially close routing of a pair of cables of different polarity to a series arrangement of solar panels to be achieved while maintaining the structured arrangement of other cables to be routed.

[0019] In one embodiment, at least two guide channels run parallel to each other. In particular, it can be provided that all guide channels run parallel to each other. This enables a particularly space-saving design of the guide element and a particularly clear arrangement of the cables to be routed.

[0020] The components of the snap-in closure can be configured as locking lugs arranged on the insertion side on the guide element and as corresponding undercut recesses on the closure element. This enables a connection in the form of a clip closure that is particularly suitable for the detachable attachment of the closure element to the guide element.

[0021] The guide element and the closure element can each have several, for example six, components of the snap-in closure. It is also conceivable for the guide element to have a larger number of components, for example 18, and in particular to be designed for simultaneous connection to several closure elements. Additionally, the components of the guide element and the closure element can each be arranged in two rows. The components of the guide element can be arranged in two rows perpendicular to the width of the guide element, and the components of the closure element can also be arranged in two rows correspondingly.

[0022] In such configurations, a connection can be achieved which is sufficiently flexible but nevertheless sufficiently secure for the detachable fastening of the closure element to the guide element.

[0023] In the guide element, two guide channels can be arranged between the components perpendicular to the width of the guide element. These can, in particular, be two adjacent, possibly parallel, guide channels. The closure element can then be designed accordingly to close these two guide channels.

[0024] The closure element can be designed to close at least two, in particular four, guide channels, in particular to close only two or only four guide channels. In this case, it can be provided that the guide element has more than two guide channels or more than two pairs of guide channels, each of which requires an additional closure element to close. In this way, cables to be routed can be inserted one after the other into the cable device and closed by fastening the closure element, thus effectively securing them against falling out. This additionally simplifies the handling of the cable routing device, in particular when used to lay a large number of cables to be routed or also when prefabricating a cable harness, as will be described below.

[0025] The closure element can have one or more protrusions or projections arranged on a closure side of the closure element for projecting into a guide channel when fastened to the guide element. In particular, it can be provided that the protrusions do not project into the guide channels 210 when the elements are released.

[0026] The closure side is the side of the closure element which, when the closure element is properly attached to the guide element, rests on the insertion side of the guide element and is thus opposite to it.

[0027] In this way, a force-locking connection between a properly secured closure element and a cable inserted in the guide channel can be achieved, and indirectly, via the snap-in closure, with the guide element. This provides strain relief for the cables routed in the cable management device.

[0028] The closure element can have beveled edges in at least one partial area, in particular in two partial areas, of a closure side of the closure element. A corresponding design with such a partial area provides a suitable starting point for the application of force for the purpose of releasing a properly fastened closure element, thereby simplifying the release of the closure element from the guide element.

[0029] In one embodiment, the cable routing device is designed for connection to at least one additional cable routing device for the purpose of a modular extension. This allows, for example, when used to lay a particularly multi-strand cable harness with more cables to be routed than the number of guide channels available in a single cable routing device, the use of multiple, but identical, cable routing devices, thus avoiding individual production for a corresponding use and thus making production particularly efficient. This allows additional guide channels for inserting a respective cable to be routed to be provided in a simple manner as needed.

[0030] In particular, the cable routing devices can be connected to one another in such a way that a plurality of parallel guide channels is provided in a particularly space-saving manner. Accordingly, a connecting region of the guide element can be designed for the attachment of a further guide element. Furthermore, it is possible for the guide element and the further guide element to overlap in the connecting region when properly attached. In addition, the guide element can have a recess in the connecting region for receiving a correspondingly designed projection of the further guide element.

[0031] The guide element and / or the closure element can be made of plastic, such as polycarbonate. This allows for a dimensionally stable and robust, yet lightweight, and, if necessary, transparent, design of the respective elements.

[0032] Furthermore, according to the invention, a prefabricated cable harness with at least one first and one second cable guide device according to the invention is disclosed, which comprises a plurality of cables, wherein each of the cables is inserted into a guide channel of the first cable guide device and the second cable guide device at a predetermined distance along its length. In particular, further cable guide devices can be provided, and each of the cables can be inserted into a guide channel of a plurality of cable guide devices at a predetermined distance along its length.

[0033] For example, the cable harness according to the invention is a cable harness which, depending on the nature of a photovoltaic system to be erected on a frame, for example depending on the position and location of elements of the frame, is pre-assembled in such a way that the cable routing devices can be fastened to elements of the frame along an intended course of the cable harness.

[0034] In this way, a cable harness tailored to the specific requirements of the system, such as the position of suitable attachment points for cable devices, can be provided in the field, regardless of weather conditions, even before the installation of a system. The individual cables can be successively routed from the cable routing device bundle according to a predefined routing plan. By using multiple cable routing devices according to the invention, a spatially organized, clear, and traceable cable routing can be provided even before the actual installation in the field, which can significantly reduce the installation effort.

[0035] Furthermore, a method for guiding a cable through a cable guiding device, in particular according to the invention, is disclosed, comprising the following steps: providing a cable guiding device with a guide element having at least two guide channels, each designed for inserting a cable to be guided, which are open towards an insertion side and extend across a width of the guide element, and a closure element designed to close the guide channel from the insertion side, wherein the guide element and the closure element each have components of a cooperating snap closure for releasable fastening to one another; inserting a cable to be guided into a guide channel of the guide element; and fastening the closure element to the guide element to close the guide channel.

[0036] In addition, a method for prefabrication of a cable harness is disclosed, comprising the following steps: providing at least one first cable guide device according to the invention having a first guide element and a first closure element, and a second cable guide device according to the invention having a second guide element and a second closure element; providing a plurality of cables, each having a length; inserting each of the provided cables at a predetermined distance along its length into a respective guide channel of the first and second guide elements; fastening at least the first closure element to the first guide element and the second closure element to the second guide element to close at least one of the guide channels of the first and second guide elements into which a cable is inserted.

[0037] For a more detailed explanation of further advantageous developments of the method, reference is made to the above-described developments of the cable routing device. The cable routing device can also be developed with further features described in connection with the method.

[0038] The embodiments and configurations described above are to be understood as examples only and are not intended to limit the present invention in any way.

[0039] The invention will be explained in more detail below with reference to advantageous embodiments and examples in the accompanying drawings. They show: Fig. 1 a schematic representation of an embodiment of a cable harness comprising several cable routing devices according to the invention and mounted on a photovoltaic system; Fig. 2-3 schematic representations of an embodiment of a cable guiding device; Fig. 4 a schematic representation of another embodiment of a cable guiding device; Fig. 5-6 are schematic representations of another embodiment of a cable guide device; and Fig. 7 a schematic representation of another embodiment of a cable guiding device.

[0040] In Fig. 1 schematically illustrates an embodiment of a cable harness 10. The cable harness 10 comprises a first and a second cable routing device 20 and a plurality of cables 30. Each of the cables 30 is guided through the first and second cable routing devices 20 and is inserted at a predetermined distance along its width in a guide channel of the first and second cable routing devices 20. The illustrated embodiment is a cable harness 10 of a photovoltaic system which, depending on the nature of the system, in particular the position and orientation of a frame of the system, can be prefabricated prior to assembly of the system such that the cable devices 20 can be fastened to elements of the frame along the intended course of the cable harness 10.

[0041] In the following, embodiments of a cable guide device are described with reference to the illustrations of the Fig. 2 to 7. Fig. 2 is a perspective view of an embodiment of a cable guide device 20 with a guide element 21 and a closure element 22, as also shown in the example of Fig. 1 have already been indicated. Fig. 3 shows a sectional view of this embodiment. In Fig. 4 is a schematic representation of another embodiment of a cable guide device 20. The Fig. 5 and Fig. 6 show another embodiment of a cable guide device 20 in different perspective views. In Fig. 4 is a schematic representation of another embodiment of a cable guide device 20. In the Fig. 2, Fig. 3, Fig. 5 and Fig. 6, the guide element 21 and the closure element 22 are each shown in a released state. Fig. 4 and Fig. 7 each show the elements 21, 22 in the properly fastened state. The guide element 21 and the closure element 22 can, for example, each be made of polycarbonate.

[0042] In the examples of the Fig. 1-4, the guide element 21 has twelve guide channels 210 that extend across a width of the guide element 21. The guide channels 210 are each designed to insert a cable 30 to be guided.

[0043] In the examples of the Fig. 1-4, all guide channels 210 run essentially parallel to one another. Two guide channels 210 are arranged directly adjacent to each other in the guide element 21.

[0044] The guide channels 210 are open toward an insertion side 201 of the guide element 21. Accordingly, the guide channels 210 have an insertion-side opening 211 along the width of the guide element 21. At this opening 211, the width of the guide channels 210 is smaller than in the interior 221 of the respective guide channel 210. The extension of the slot-like opening 211 perpendicular to the width of the guide element 21 is smaller than the maximum extension of the guide channel 210 in this direction.

[0045] The closure element 22 is designed to close four guide channels 210 from the insertion side 201. The closure element 22 has a closure side 202, which is the side of the closure element 22 that rests on the insertion side 201 of the guide element 21 when the closure element 22 is properly fastened to the guide element 21. Accordingly, with such proper fastening, the closure side 202 is opposite the insertion side 201.

[0046] The closure element 22 comprises several, in the example of Fig. 2-4 six protrusions 212 arranged on the closure side 202. When the closure element 22 is properly secured to the guide element 21, the protrusions 212 each protrude into one of the guide channels 210. In two partial areas 222 of the closure side 202, the closure element 22 has beveled edges.

[0047] The guide element 21 and the closure element 22 each have components 51, 52 of a cooperating snap-in closure for releasably securing them together. On the guide element 21 side, the components of the snap-in closure are designed as locking lugs 51 arranged on the insertion side 201. On the closure element 22 side, the components of the snap-in closure are designed as corresponding undercut recesses 52.

[0048] The closure element 22 comprises six recesses 52, and the guide element 21 comprises 18 locking lugs. The locking lugs 51 are arranged in two rows perpendicular to the width of the guide element 21. The recesses 52 are also arranged in two rows correspondingly. Between the locking lugs 51, two directly adjacent guide channels 210 are arranged perpendicular to the width of the guide element 21.

[0049] The Fig. 1-4 is designed in such a way that three closure elements 22 can be fastened next to one another on the guide element 21 by means of a snap-in closure, as is also the case in the examples of Fig. 1 and Fig. 4 - there shown in the properly fastened state.

[0050] The cable guide device 20 is designed to be connected to at least one further cable guide device 20a for the purpose of a modular extension, which in turn comprises a further guide element 21a and a further closure element 22a. A connecting region 40 of the guide element 21 is designed for fastening the further guide element 21a. When properly fastened to one another, as shown in Fig. 4, the guide element 21 and the further guide element 21a overlap in the connecting region 40. The guide element 21 has a recess 42 in the connecting region 40, which is designed to receive a corresponding projection 41a of the further guide element 21a.

[0051] In the examples of the Fig. 5-7, the guide element 21 has eight guide channels 210 that extend across a width of the guide element 21. The guide channels 210 are each designed to insert a cable 30 to be guided. Two guide channels 210 are arranged directly adjacent to each other in the guide element 21.

[0052] The guide channels 210 are open toward an insertion side 201 of the guide element 21. Accordingly, the guide channels 210 have an insertion-side opening 211 along the width of the guide element 21. Additionally, the guide channels 210 are open on a side perpendicular to the insertion side 201.

[0053] In each of the guide channels 210, two retaining clips 241 are arranged at the insertion-side opening 211 for releasably holding the guiding cable 30 in the respective guide channel 210. The retaining clips 241 are designed such that they each limit the movement of a cable 30 to be guided toward the insertion side 201 and each enable the movement of the cable 30 to be guided toward the side perpendicular to the insertion side 201, toward which the guide channels are open.

[0054] The closure element 22 is designed to close at least one of the guide channels 210, in the example shown, from the insertion side 201. The closure element 22 has a closure side 202, which is the side of the closure element 22 that rests on the insertion side 201 of the guide element 21 when the closure element 22 is properly fastened to the guide element 21. Accordingly, with such proper fastening, the closure side 202 is opposite the insertion side 201. The closure element 22 is rotationally symmetrical to a vertical axis and has a handle 232.

[0055] The guide element 21 and the closure element 22 each have components 51, 52 of a cooperating snap-in closure for releasable fastening to one another. In the embodiments of the Fig. 5-7, the snap-in closure is designed as a rotary snap-in closure. The components 51 of the snap-in closure on the closure element 22 side are formed as two lugs 52 formed on a shaft and movable through corresponding openings 231 in the guide element 21. The lugs 52 are movable through the openings 231 only in a first and a second orientation of the closure element 22 relative to the guide element 21, wherein the second orientation corresponds to a rotation of the closure element 22 by 180 degrees relative to the first orientation.

[0056] After passing through the openings 231, the lugs 52 can be brought into components of the snap-in closure, formed as corresponding undercuts 51, on the side of the guide element 21 by rotating the closure element 22 by 90 degrees relative to the guide element 21. In this way, the elements 21, 22 can be transferred from the detached state to the properly fastened state.

[0057] The closure element 22 comprises several, in the examples of Fig. 5-7 two protrusions 212 arranged on the closure side 202. The protrusions 212 are formed on the closure element 22 in such a way that they protrude into the guide channels 210 when the elements 21, 22 are properly fastened to one another, and do not protrude into the guide channels 210 when the elements 21, 22 are released.

[0058] The Fig. 5-7 is designed in such a way that four closure elements 22 can be fastened next to one another on the guide element 21 by means of a snap-in closure, as is also the case in the example of Fig. 7 - there shown in the properly fastened state.

[0059] Analogous to the examples of the Fig. 1-4 is also the cable guide device 20 of the Fig.5-7, the cable guide device is designed for connection to at least one further cable routing device for the purpose of a modular extension, which in turn comprises a further guide element and at least one further closure element. A connecting region 40 of the guide element 21 is designed for fastening the further guide element. When properly fastened to one another, the guide element 21 and the further guide element overlap in the connecting region 40. The guide element 21 has a recess 42 in the connecting region 40, which is designed to receive a correspondingly configured projection of the further guide element. This projection of the further guide element corresponds in its design to the projection 41 of the guide element 21.

[0060] In a method for guiding a cable 30 through a cable guiding device 20, a cable guiding device 20 is first provided with a guiding element 21 having at least two guiding channels 210 each designed to insert a cable 30 to be guided, said guiding channels being open toward an insertion side 201 and extending across a width of the guiding element 21. Furthermore, a closure element 22 designed to close the guiding channel 210 from the insertion side 201 is provided, wherein the guiding element 21 and the closure element 22 each have components 51, 52 of a cooperating snap-in closure for releasable fastening to one another. The cable 30 to be guided is inserted into a guiding channel 210 of the guiding element 21, and the closure element 22 is fastened to the guiding element 21 to close the guiding channel 210.

[0061] In a method for prefabrication of a cable harness, at least a first and a second cable routing device 20, each with a guide element 21 and a closure element 22, are provided, as well as a plurality of cables 30, each of a length. Each of the provided cables 30 is inserted at a predetermined distance along its length into a respective guide channel 210 of the guide elements 21 of the first and second cable routing device 20. One of the closure elements 22 is fastened to the guide element 21 of the first cable routing device 20, and another of the closure elements 22 is fastened to the guide element 21 of the second cable routing device 20, in order to close at least one of the guide channels 210 of the guide elements 21, into which a cable 30 is inserted. These steps are repeated, if necessary, with further cable routing devices, whereby individual cables can be laid according to a predetermined laying plan, i.e.Once a certain length has been reached, it no longer needs to be inserted into the next cable routing device. The cable harness can be conveniently rolled up for easy and space-saving transport to the installation site.
