Description

[0001] CABLE GUIDE DEVICE WITH CABLE TIES

[0002] The invention relates to a cable guide device, in particular an energy guide chain, for guiding lines, such as cables, hoses or the like, between two connection points that are movable relative to one another, wherein the cable guide device comprises a single link plate strand with link plates that are articulated to one another and can be bent relative to one another. The invention further relates to a link plate strand for the cable guide device according to the invention, a link plate for the link plate strand or the cable guide device, and a method and use of the link plate.

[0003] Cable guide devices with a single link plate strand are known, with such cable guide devices having two crosspieces attached to at least one side in the edge regions of the link plate. The crosspieces are essentially rigid and can be connected to one another at their free ends by a likewise rigid connecting piece.

[0004] Such cable routing systems are suitable for normal to high loads and travel speeds, but are relatively heavy and feature a complex construction. Chain plates of various heights and crosspieces of various lengths are available for different numbers of cables and different cable cross-sections. If the cross-section of a space for accommodating the cables needs to be changed, the chain plates and / or crosspieces must be replaced.

[0005] A further development of such cable guide devices is disclosed in WO 02 / 25790 A1. One embodiment of the energy guide chains disclosed therein comprises a single link strand with link plates that are connected to one another in an articulated manner and can be bent relative to one another and are provided with a cable tie.

[0006] Cable ties are well known and are a widely used means for holding objects together and securing them, in particular lines such as cables or the like. A cable tie usually comprises a locking head and a locking band on the locking head. The locking band is flexible and / or elastic. The locking band can be brought into engagement with the locking head at the end to close the cable tie, thereby forming a loop. For this purpose, the locking head often has a locking tongue which can be brought into engagement with and locked into corresponding and regularly arranged locking elements of the locking band.

[0007] One of the chain links according to the embodiment disclosed in WO 02 / 25790 A1 has a passage. The cable tie is fastened to the chain link by guiding its fastening strap through openings in the chain link, whereupon the cable tie is closed to form a loop. The loop provides a space on the chain link for accommodating cables. By tightening the loop and the resulting reduction in the cross-section of the space, cables arranged in the space can be fastened or lashed to the chain link. This enables the cables to be fixed section by section to the chain link for guiding the cables.

[0008] The cable guide device disclosed in WO 02 / 25790 A1 represents a simple and adaptable solution compared to conventional cable guide devices and makes it possible to accommodate different numbers of cables and different cable cross-sections. However, it has been found that guiding the cable tie through the chain link and closing it is comparatively laborious and prone to errors. Furthermore, after closing, the locking head is usually arranged at a randomly selected location on the held cables on a side opposite the chain link. This leaves the locking head unprotected and / or puts strain on the held cables. This can lead to damage to both the locking head and the cables, and can even lead to failure of the cable tie.

[0009] GB 2 200 716 A describes a link chain for guiding cables and hoses using endless belts to attach the cable / hose to the body of a link of the link chain.

[0010] The object according to a first aspect of the present invention is therefore to provide a cable guide device or a suitable link plate for a cable guide device that at least partially eliminates at least one of the aforementioned disadvantages. In particular, the invention is intended to enable the provision of a robust and easy-to-handle cable guide device.

[0011] According to the invention, this object is achieved in one aspect by a cable guide device according to claim 1. One aspect of the invention is the special design of the chain link. The cable guide device according to the invention comprises in particular a single link chain strand with chain links which are connected to one another in an articulated manner and can be angled relative to one another, and at least one cable tie with a locking head and a locking strap on the locking head. At least one, several of the chain links or all of the chain links of the strand each have a passage through which the locking strap can be or is passed through at least a section in such a way that the cable tie can be closed to form a loop, forming a space on the chain link for receiving the cables. For closing, in particular a section of the locking strap passed through the passage is fastened to the locking head.Cables in the room can preferably be secured by lashing the cable tie to the respective chain link.

[0012] The chain link, which has the passage, comprises a holding receptacle for holding the closure head, wherein the holding receptacle is arranged at one end of the passage. At the respective end of the passage, the closure band can be pushed into or out of the passage. The passage is preferably integrated into the link body of the chain link as a type of channel. The closed cable tie is reliably held on the chain link by the passage. Generally speaking, the passage and holding receptacle interact in such a way that movement of the closed cable tie relative to the chain link is largely prevented.

[0013] The design according to the invention firstly provides a predefined location for arranging the locking head and secondly facilitates closing the cable tie by holding the locking head in a position suitable for closing. For closing, it is no longer necessary to temporarily fix the cables, cable tie and chain link relative to one another, since the cable tie can be actuated like an integral part of the chain link. The cables can thus be positioned on an upper side of the chain links, after which a precise positional fixation of the cables relative to the chain link or to the cable guiding device is ensured by closing the cable tie and reducing the cross-section of the space provided by the loop. The cables do not have to be lifted off again to close the cable tie.

[0014] Preferably, the retaining receptacle is accessible from several, in particular two, sides of the link plate, in particular from a side facing the cables during operation of the cable guide devices and a side perpendicular thereto. This enables easy handling of a closure head held by the retaining receptacle and, in particular, easy release from the retaining receptacle, while preventing accidental release.

[0015] The cable guide device according to the invention is particularly suitable for movement on a horizontal support. The chain links then rest with their undersides on the support. The cables can then be easily placed on the upper side of the respective chain link, which then faces upwards. When the cable tie is closed, it fits tightly, possibly under pretension, around the circumference of the inserted cable harness.

[0016] Preferably, the retaining receptacle is designed to fix the cable tie relative to the chain link by holding the closure head before the fastener band is passed through the passage. In particular, the retaining receptacle is arranged relative to one end of the passage such that the cable tie can be fastened to the closure head arranged in the retaining receptacle by continuing a passage movement performed when the fastener band is passed through the passage.

[0017] Preferably, the holding receptacle for holding a locking head of a cable tie is designed such that the locking head is held in the holding receptacle in a form-fitting and / or force-fitting manner such that, on the one hand, the cable tie remains held securely on the tab when the locking head is held in the holding receptacle, but on the other hand, the locking head can be removed from the holding receptacle by hand, e.g. for the purpose of replacing cables during maintenance and the associated replacement of the cable ties. This can be achieved in particular by suitable dimensioning and / or design of the holding receptacle in relation to commercially available sizes of cable ties.

[0018] In order to enable the closure head to be arranged at any end of the passage, the chain link can comprise a further holding receptacle arranged at the other end of the passage. The chain link therefore preferably has a holding receptacle at each end of the passage for holding the closure head. The closure head can therefore be arranged optionally in one of the holding receptacles of the chain link. In particular, the cable tie can therefore be guided from one end of the passage to the other end of the passage to the closure head or from the other end of the passage to one end of the passage to the closure head.

[0019] Particularly for guiding longer, stiffer and / or heavier cables in longer cable guide devices, it can be expedient to design a plurality of chain links of the link chain strand as described above. According to one embodiment, several, in particular all, of the chain links therefore have a passage through which the fastening strap of a cable tie can be passed such that the cable tie can be closed into a loop, forming a space on the respective chain link for receiving the cables. In this embodiment, these chain links each have a holding receptacle arranged at one end of the passage for holding a locking head of a cable tie. Generally speaking, the cable guide device preferably comprises a plurality of cable ties for the respective chain links.

[0020] The invention further relates to a link plate strand, in particular for a cable guide device. The link plate strand comprises link plates which are connected to one another in an articulated manner and can be angled relative to one another, at least one link plate of which has a passage through which a fastening strap of a cable tie can be passed such that the cable tie can be closed into a loop, forming a space on, in particular an upper side, of the link plate for receiving cables, the link plate having a holding receptacle arranged at one end of the passage for holding the locking head. Preferably, at least half of the link plates or all of the link plates of the strand each have a holding receptacle for holding a locking head of a cable tie.

[0021] The individual link plates of the link chain strand can each have features which are disclosed herein in connection with the cable routing device according to the invention. In a particularly simple embodiment, the link chain strand comprises at least three link plates, of which at least the middle link plate, i.e. the link plate which is articulated to the other two link plates and can be angled relative to each of them, has the described passage and the described holding receptacle. Generally speaking, the link plate preferably comprises two hinge regions, each of the hinge regions being articulated to a hinge region of another link plate in order to arrange a plurality of link plates to form the link chain strand. The hinge regions are preferably designed as overlap regions, i.e. when link plates are connected, they overlap with overlap regions of adjacent link plates.If the link plate forms an end link of a link strand designed for connection to one of the connecting areas, this link plate can have only one joint area instead of both joint areas. For all embodiments, the passage and / or retaining receptacle are preferably arranged next to the respective joint area, thereby avoiding excessively tight bending radii when routing cables.

[0022] According to a preferred embodiment, the link plates are designed to be offset. For this purpose, each link plate has a region that is offset outwards with respect to the passage and an inwards, wherein the offset regions each have connecting means for the articulated connection of the link plate to adjacent link plates. If link plates are joined together to form a link chain, the inwards offset region of an adjacent link plate rests on the inside of the outwards offset region of one of the link plates.

[0023] Preferably, the passage for the cable tie and in particular the respective holding receptacle is arranged between the two cranked areas of the chain plate, which is structurally advantageous for holding cables.

[0024] The simple construction can also be achieved if, for the articulated connection of the chain plates to one another, pins are provided in one joint area and corresponding openings are provided in the other joint area of ​​each or the respective chain plate.

[0025] A link plate according to the invention can thus preferably have a pin in one joint area and corresponding openings in the other joint area for the articulated connection of link plates to one another. In particular, the link plates can thus be designed identically and assembled in any desired arrangement to form a link plate strand.

[0026] In one embodiment, a locking connection is provided between the pins and openings of the link plates. This is preferred because it allows for a simple, articulated connection of the link plates to form a link chain.

[0027] The invention particularly relates to a chain link plate. The chain link plate is preferably suitable for a cable guide device according to the invention and / or a link plate strand according to the invention.

[0028] The chain link according to the invention comprises a passage through which a closure strap of a cable tie can be passed such that the cable tie can be closed into a loop, forming a space on the chain link for receiving cables. The chain link has a holding receptacle arranged at one end of the passage for holding a closure head of the cable tie.

[0029] The link plate may comprise further features described in connection with the cable guide device according to the invention or the link plate strand according to the invention. For example, the link plate preferably has two joint regions for articulated connection to a further link plate, in particular as described above. Furthermore, the link plate may have a pin and a corresponding opening in each joint region.

[0030] In general, the chain link particularly preferably comprises a guide section for guiding the fastener tape relative to the passage. The guide section ensures that a section of the fastener tape passed through the passage is guided relative to the closure head for easy closing of the cable tie and / or for guiding a section of the fastener tape away from the closure head after closing. The guide section is preferably arranged completely outside the passage. In one embodiment, the holding receptacle is arranged at least partially between the passage and the guide section. As a result, the passage and holding receptacle can be arranged at a distance from one another. In particular, the holding receptacle extends from the passage to the guide section in order to ensure particularly reliable guidance of the fastener tape. In general, the holding receptacle, passage and guide section are preferably arranged one behind the other.This allows a section of the closure band emerging from the passage to be closed with the closure head without further deflection. At the same time, even with a simple design, proper functionality of the retaining device is ensured.

[0031] In one embodiment, the chain link comprises a further holding receptacle arranged at the other end of the passage. The further holding receptacle can have features described in connection with the first-mentioned holding receptacle. It is designed essentially mirror-symmetrically to the first-mentioned holding receptacle and makes it possible to close a cable tie alternatively at the other end of the passage, wherein its closing head can be held by the holding receptacle at the other end of the passage. A further guide section can be provided accordingly. In particular, the passage runs between the holding receptacles, i.e. essentially from one holding receptacle to the other.

[0032] Generally, the respective retaining receptacle is preferably designed to delimit a receiving space in which the locking head of a cable tie can be arranged such that the retaining receptacle encloses the locking head from several sides to hold the locking head in the receiving space. The retaining receptacle can be designed as a recess in a link plate body of the chain link. For better handling, the recess can be designed to be open on one side with a wider cross-section.

[0033] Particularly preferably, the respective retaining receptacle or retaining means is arranged in an edge region of the link plate. The respective edge region extends along the narrow sides of the respective link plate. The passage is preferably arranged centrally between the edge regions, which enables symmetrical load distribution.

[0034] To provide improved protection for the cable tie and the connection it provides during movement, the link plate can be designed such that the passage ends toward the top of the link plate, where the space for accommodating the cables is formed. The passage is thus accessible from the top at the end. If the link plate is used for movement on a horizontal base, contact between the cables and cable ties and the base, thus preventing potential damage, is avoided.

[0035] According to a preferred embodiment, the passage has, between its open ends, a particularly elongated opening to the underside of the link plate. The ends of the passage and the opening are therefore preferably located on opposite sides of the link plate, namely the ends on the top side and the opening on the underside. This simplifies the manufacture of the link plates. The link plates according to the invention are generally preferably made of plastic, in particular of tribologically optimized plastic. Link plates are preferably manufactured by injection molding. By providing the openings described, undercuts can be largely avoided during the construction of the link plate, which avoids long cycle times and the need for complex tools, particularly in injection molding processes.The opening preferably extends over at least 20%, in particular a maximum of 90%, in particular 30% to 100%, of the length of the passage.

[0036] According to an independent second aspect, special designs of a chain plate, in particular designed with features according to the first aspect, are proposed, whereby increased fatigue strength is ensured without over-dimensioning or the need for a stronger design using additional material. In addition, the possibility should be opened up for further weight savings by reducing the wall thicknesses or the plastic mass in the chain plate. Such a chain plate has a pin, in particular as described above, in a joint area. The pin can be connected to a corresponding opening in a further chain plate for the articulated connection of the chain plate to the further chain plate.

[0037] As long-term studies in the applicant's test laboratory have shown, link plates can fail even at conventional rounded cross-sectional transitions, such as those along the link plate's pivot and at the transition between the pivot and the link plate body, presumably due to residual stress concentrations or material stresses, after a high limit of load cycles. This also occurs at loads far below the static strength or load-bearing capacity and sometimes before other sharp-edged transitions in the force flow fail. Accordingly, the usual circular radius transitions do not appear to be optimal.

[0038] To reduce or eliminate these disadvantages, according to one aspect of the invention, a specially shaped cross-sectional transition is provided on the pin. It is proposed that this selected cross-sectional transition be defined by an enveloping transition curve with a special profile, the cross-sectional area of ​​the cross-sectional transition decreasing continuously along the transition curve from the start point to the end point, in particular decreasing monotonically (in the sense of the corresponding curve function). The profile of the transition curve according to the invention is set such that for a selected starting point of the transition curve in or on the first partial surface, which lies at a distance A to the imaginary intersection curve of the first partial surface with the second partial surface, the curve end point is in or on the first partial surface.on the second partial surface at a predetermined, greater distance Z to this intersection curve, namely a distance Z with 1,7 • A < Z < 4,0 • A, in particular with 2,3 • A < Z < 3,4 • A.

[0039] In short, the transition in the cross section of such a tenon is designed according to a monotonically falling curve, which is selected or constructed in such a way that its end point distance Z to the intersection curve of both adjacent surfaces is significantly greater than its corresponding starting point distance A, namely in particular in the range 1.7 < Z / A < 4.0.

[0040] Such a cross-sectional transition is

[0041] Fatigue damage, particularly local stress concentrations or stress peaks caused by force flow, is significantly more advantageous than conventionally designed quarter-circle fillet radii. The cross-sectional transition can be scaled to suit any design space or boundary conditions. For flat surfaces, the intersection curve, for which the distance between the start and end points is considered, corresponds to a straight line. For a cylindrical journal surface or a transition surface of the journal that is curved in the plane of the tab, however, the intersection curve is not a straight line. The enveloping transition curve is preferably constant along the cross-sectional transition, at least in some areas or predominantly, i.e. an envelope or enveloping curve to the outer surface of the cross-sectional transition.

[0042] It is particularly advantageous if the transition curve corresponds, in terms of functional analysis or mathematically, to a smooth or continuously variable and strictly monotonically decreasing curve. The radius of curvature can be constant, at least in some areas along the curve. A partially or completely curvature-continuous curve with a starting point distance A and an end point distance Z in the ratio range 1.7 < Z / A < 4.0 can also be used.

[0043] Irrespective of the distance ratio Z / A, a cross-sectional transition is also proposed which is defined by a transition curve which is smooth (continuously) and strictly monotonically decreasing and which is characterized by special properties of its curve tangent or curve gradient (or first derivative or differential quotient) relevant for the force flow along its course. A transition curve is selected whose curve tangent at the starting point (in extreme case) intersects the first surface at an angle of approximately 45° + / - 10°, in particular + / - 5°, and whose curve tangent rotates progressively or monotonically along the course of the curve in a direction parallel to the second surface and at the end point is preferably almost (+ / - 10°, preferably + / - 5°) or technically parallel to the second surface.

[0044] The transition curve can comprise several continuously merging, for example straight sections, which are constructed, for example, according to a method suitable for relieving notch stresses,

[0045] The risk of incipient cracks under dynamic loading at cross-sectional transitions is significantly reduced with the proposed transition contour. As is known from metal materials science, such incipient cracks could also occur in comparatively more flexible polymer plastics under alternating loads and grow until they reach residual fracture. Accordingly, the use of cross-sectional transitions shaped as described enables the production of operationally durable chain links without additional material expenditure. Material savings can also be achieved, particularly compared to existing chain link designs, by avoiding or specifically eliminating unnecessary oversizing.

[0046] Particularly in the case of link plates designed for one-sided overlap only, such as offset link plates, experience has shown that critical areas are where forces flow from an area primarily extending in the main plane of the link plate to an area predominantly extending perpendicular to it. The teachings described with regard to the design of the pin can be applied accordingly. Thus, a transition curve is preferably placed with its starting point on or in a first partial surface perpendicular to the main plane of the link plate, and correspondingly, the end point in a second partial surface parallel to the main plane of the link plate body.

[0047] Preferably, the link plate is articulated to adjacent link plates by a locking connection between the pin and the opening. In one embodiment, the pin has a bead for engaging behind the corresponding opening during the locking connection. The cross-sectional transition to the bead can be designed according to the above-mentioned teaching.

[0048] To form the bead according to this teaching, the pin has a cross-sectional transition between two outer partial surfaces, which is rounded or broken between a first partial surface and a second partial surface running at an angle to this, wherein the cross-sectional transition is limited by an enveloping transition curve with a course such that for a starting point of the transition curve on the first partial surface, which is at a distance A to the intersection curve of the first partial surface with the second partial surface, the end point of the transition curve on the second partial surface is at a distance Z to this intersection curve, with 1.7 • A < Z < 4.0 • A, in particular with

[0049] 2, 3 • A < Z < 3, 4 • A, and that the cross-sectional area of ​​the cross-sectional transition decreases continuously along the transition curve from the starting point to the end point, whereby in particular the transition curve corresponds to a smooth or stepless and strictly monotonically decreasing curve.

[0050] The invention also relates to a method for producing a cable guide device, in particular according to the invention, in particular an energy guide chain according to the invention. The invention also relates to the use of a link plate strand according to the invention and / or a chain plate according to the invention for the cable guide device. The method or use comprises the steps of arranging a closure head of a cable tie in a holding receptacle of the chain plate; preferably guiding a closure strap of the cable tie through a passage of a chain plate; and closing the cable tie to form a loop for holding cables in a space formed by the loop on the chain plate. The cable tie is particularly preferably closed to form a loop by attaching the closure strap to the closure head with a section passed through the passage.The closure head is preferably arranged in the holding receptacle, which facilitates closing.

[0051] Further advantageous features and effects are explained below, without limiting the generality of the foregoing, using preferred embodiments with reference to the accompanying drawings. Herein:

[0059] Fig. 1A shows a perspective view of an exemplary embodiment of a chain plate 1 according to the invention with the upper side facing towards the user. Fig. 1B shows a perspective view of the same exemplary embodiment with the upper side facing away. The chain plate 1 is made in one piece, which is generally preferred. The chain plate 1 comprises two joint regions and, between them, a region in which a passage 11 is arranged. The passage 11 is thus arranged centrally, which is generally advantageous. A fastening strap of a cable tie (not shown) can be passed through the passage 11. The chain plate 1 is provided with holding receptacles 12a, 12b at both ends of the passage 11.

[0060] The holding receptacles 12a, 12b are each arranged in an edge region of the chain plate 1, wherein the respective holding receptacle 12a, 12b widens towards the narrow side of the chain plate 1, which is not necessary, but is generally advantageous due to improved handling. The holding receptacles 12a, 12b are each designed as a recess let into the plate body of the chain plate 1, which recess partially encloses a locking head of a cable tie inserted from above into the respective holding receptacle 12a, 12b and thus holds it in position perpendicular to it. The holding receptacles 12a, 12b are modeled on the cross-section of a locking head of a cable tie.

[0061] On the opposite side of the link plate 1 (see Fig. 1B), the passage 11 is opened by an elongated opening 112, which simplifies the manufacture of the link plate 1. Despite the opening 112, a fastening strap of a cable tie running in the passage can be sufficiently protected, since a fastening strap arranged in the passage 11 would always be spaced from the outside of the link plate.

[0062] Fig. 2A shows a plan view of a narrow side of the exemplary embodiment shown in Figs. 1A and 1B. Fig. 2B shows a sectional view based on the plan view of Fig. 2A. The section line on which the sectional view of Fig. 2A is based is marked in Fig. 2A. Furthermore, in Fig. 2A a section X of the chain plate 1 is marked by a dashed ellipse. The section X is shown schematically in Fig. 3B.

[0063] The passage 11 runs in a straight line between the holding receptacles 12a, 12b, with its ends 111a, 111b directly adjoining the holding receptacles 12a, 12b. The opening 112 extends along the entire length of the passage 11, thereby ensuring that the chain link can be manufactured as an injection-molded part without an undercut. The holding receptacles 12a, 12b are each open towards an opposite narrow side of the chain link 1 and towards a common side. In this way, a locking head of a cable tie can be inserted into the respective holding receptacle 12a, 12b and held by it. The locking strap of the same cable tie can be inserted into the passage 11 on the opposite side, guided through the passage 11 and closed with the locking head. A possibly...Excess section of the fastener tape can be moved beyond the respective holding receptacle 12a, 12b in the direction of the respective narrow side. The chain plate 1 is cranked. With regard to the centrally arranged passage 11, an outwardly cranked region 31 and an inwardly cranked region 32 are provided. With such a design, several chain plates can be arranged essentially flush next to one another and connected in an articulated manner. For this purpose, the chain plate has a joint region with a pin 33 and an opening 34 in each of the cranked regions 31, 32, which is advantageous. Other design variants of such joint regions are, however, known. Opening 34 and pin 33 are designed to correspond, and can therefore be plugged into a corresponding opening 34 or a corresponding pin 33 of an adjacent chain plate for connection to further chain plates 1.A locking connection is then formed between the opening 34 and the pin 33 of adjacent link plates. To enable a reliable locking connection, the pin 33 has a bead at its end for engaging behind the respective corresponding opening.

[0064] The stud 33 has a specially shaped cross-sectional transition, which is designed according to a monotonically decreasing curve. This curve is selected or constructed such that its endpoint distance from the intersection curve of both adjacent surfaces is significantly greater than its corresponding starting point distance. This helps prevent stress peaks. Further details on the cross-sectional transition can be found in Figs. 3A and 3B.

[0065] Fig. 3A shows a section X from Fig. 2A of the pin of the corresponding embodiment. Fig. 3B shows a schematic representation of a transition curve C associated with the cross-sectional transition of the pin 33.

[0066] The pin 33 has at one end a

[0067] Cross-sectional transition Q between a first partial surface Fl and a second partial surface F2 which is angled to this. The pin is designed in such a way that the course of the cross-sectional transition Q can be represented by an enveloping transition curve C. The transition curve C has a course such that for a starting point PS of the transition curve C on the first partial surface Fl, which lies at a distance A to the intersection curve of the first partial surface Fl with the second partial surface F2, the end point PE of the transition curve C on the second partial surface F2 lies at a distance Z to this intersection curve. The distance Z is approximately 2.5 • A. The course of the transition curve follows a radius of curvature R. The cross-sectional area of ​​the cross-sectional transition Q decreases continuously along the transition curve C from the starting point PS to the end point PE.

[0068] Fig. 4 shows a perspective view of the exemplary embodiment, wherein the cable tie 2 is guided through the passage 11 and shown closed. The cable tie 2 is thus shaped into a loop by means of its bent-over fastening band 22 and delimits a space on the chain link 2 for receiving cables. Such a cable tie 2 can be purchased commercially in various sizes. The fastening head 21 of the cable tie 2 is arranged in one of the holding receptacles 12a, 12b and is held thereby. The fastening band 22 is guided through the passage 11 to the fastening head 21 and closed therewith by one of several rib-like locking elements of the fastening band engaging a locking tongue of the fastening head. A section of the fastening band 21 projects beyond the chain link 1 and protrudes. This section can be cut off for easier handling.

[0069] Fig. 5 shows a perspective view of a section of an embodiment of an energy guide chain 100 according to the invention with cables 101 guided through the energy guide chain 100. The energy guide chain 100 has a single link plate strand 10 with link plates 1 which are connected to one another in an articulated manner and can be angled relative to one another and which are each designed as described above. A cable tie 2 is provided for and connected to each link plate 1 of the link plate strand 10. For the sake of clarity, only one of the link plates 1 and only one of the cable ties 2 is provided with a reference symbol in Fig. 4. Each of the link plates 1 is designed according to the invention. This is advantageous, but not necessary. For the purpose of the invention, it is sufficient, for example, if, with the number of link plates 1 of the link plate strand 10, several link plates 1 spaced apart by link plates are designed according to the invention.For example, every second of the chain plates 1 can be designed according to the invention, while the remaining chain plates connect the chain plates 1 according to the invention in an articulated manner without any cable fastening.
