Description

[0001] The invention relates to a device for guiding at least one wire with a base body, wherein at least one eyelet is arranged in the base body, and wherein at least one wire can be guided through each eyelet.

[0002] For example, in electrical engineering, electrical conductors made of thin individual wires, which are therefore easy to bend, are used. These are called stranded wire. Copper is predominantly used as the conductor material, but other materials can also be used. To produce the stranded wire, the individual wires are fed into a stranding machine. In this device, the individual wires are braided together to form the stranded wire.

[0003] In a stranding machine, a predetermined number of wires are stranded at a stranding point, preferably by means of a rotating frame. Stranding devices can be, for example, single-stitch stranding machines with one stranding point or double-stitch stranding machines with two stranding points.

[0004] Often, the wires fed into a stranding machine are drawn to a predetermined diameter using a wire drawing device.

[0005] Such a device, comprising a stranding machine, is part of the prior art (DE 10 2013 004 592 A1). According to this prior art, the stranding device has a rotating bracket or a rotor, which is configured to guide the strand, wherein at least one cross-sectional control device is arranged at an end of the rotating bracket furthest from the stranding point.

[0006] As already explained, at least two wires are fed into the stranding machines in order to produce a strand from these wires.

[0007] However, the feeding of wires also occurs in other fields. The present invention is not limited to stranding machines. The present invention can also relate to machines in the textile industry or to other machines for processing wires, threads, or fibers.

[0008] It is known in practice to guide the wires through a guiding device so that they are fed to the stranding point of the stranding machine at a predetermined angle. As is known in practice, the wires are passed through eyelets in the device.

[0009] Since the wires are deflected within the guide device, they each rest against a specific position on the inner diameter of the eyelets. One eyelet is provided for each wire.

[0010] The manufactured strands have a length of several thousand meters, so the wires must be reliably fed through the eyelets.

[0011] Since the wires always lie at a position of the inner diameter of the respective eyelet, the eyelets wear out particularly quickly at this point.

[0012] In practice, it is known that eyelets need to be replaced when they reach a certain level of wear. This requires cutting the connecting wires. The eyelets are then removed from the holder, which is usually very time-consuming, as they are often glued in place. If the eyelets are glued in, the adhesive must be loosened, for example, by heating. Another common method is to knock the eyelets out of the holder and insert new ones.

[0013] These devices, known from practical experience, have the disadvantage that the eyelets need to be replaced relatively frequently if the eyelet becomes worn in one place.

[0014] Secondly, the eyelets cannot be replaced during operation. This means that the feed wires must be cut to replace the eyelets. This is very time-consuming, as the stranded wire is manufactured in predetermined lengths of, for example, 5,000 or 6,000 meters. If one or more eyelets of the feeder are worn out after, for example, 4,000 meters, this negatively impacts the quality of the stranded wire if the wires have to be cut and then reconnected to replace the eyelets.

[0015] A fairlead for winches is part of the prior art (EP 1 035 068 A2). This fairlead has a component that can be rotated by 90° or other angles when worn. The component is secured with a locking bracket. The locking bracket, in turn, is held in a detent position by a locking bolt connected to the housing. This prior art device is very complex, especially when a large number of components need to be rotated.

[0016] Furthermore, a thread guide is part of the prior art (JP S58 137673 U). This thread guide is also rotatably arranged in a base body. Fixing the thread guide in a predetermined position is not provided, so wear at a defined point cannot be adjusted.

[0017] Furthermore, prior art (US 4,317,549 A) ​​includes a device that can be used for wire production. An eyelet through which the wire is guided can be arranged in various angular positions. This publication discloses a wire guide housing constructed from an elastomer material such that a conventional metallic wire guide can be quickly snapped in and out, thereby significantly reducing maintenance time and costs. The snap-in design allows the metallic guide to creep in the direction of rotation, thus compensating for wear on the wire contact surface of the guide. Arrangement in predetermined angular positions is not provided for in this prior art. For this reason, free creep in the direction of rotation is possible without the eyelet assuming a predetermined position, namely a position that is not yet subject to wear.

[0018] Furthermore, a ceramic yarn guide unit is part of the prior art (CN 112 978 501 A). The ceramic yarn guide seat is rotatably mounted in a plate. A predetermined angular position of the yarn guide seat is not provided for in this prior art.

[0019] The prior art (DE 10 2017 004 271 A1) includes a composite bushing with a wear plate. According to this prior art, a wear insert is provided, which is arranged in a frame. The wear insert is made of a harder material than the frame. The frame can, for example, be made of a polymer, while the wear insert is made of metal or a metal alloy. The wear insert is fixed in the frame, as it snaps into place. This prior art device has the disadvantage that when a part of the wear insert wears out, the entire wear insert must be replaced along with the frame, and that the wear insert does not have a long service life.

[0020] Furthermore, a container for providing cable material is part of the prior art (G 88 04 516 U1). This container is designed to stand or lie next to a workstation. The container's lid should be made of transparent plastic or another material that allows visual inspection of the cable material supply. To prevent excessive wear on the lid, a dispensing opening is provided, in which a lining is securely positioned. This lining protects the opening from the stresses caused by pulling out the cable and absorbs them with virtually no wear. This prior art device provides no guidance on how to increase the service life of eyelets through which a wire is threaded.

[0021] The technical problem underlying the invention is to provide a device for guiding at least one wire, in which, firstly, the service life of the eyelets is increased and, secondly, the device can continue to be operated without cutting the wires when wear occurs. Furthermore, a device is to be provided in which the eyelets or retaining elements of the eyelets can be rotated very easily about their longitudinal axis.

[0022] This technical problem is solved by a device having the features according to claim 1.

[0023] The device according to the invention for guiding at least one wire with a base body, wherein at least one eyelet is arranged in the base body, wherein at least one wire can be guided through each eyelet, wherein the at least one eyelet can be arranged in the base body in at least two angular positions, and wherein the eyelet is detachably arranged in the base body in a form-fit and force-fit manner, or wherein the eyelet is arranged in a retaining element, and wherein the retaining element is detachably arranged in the base body in a form-fit and force-fit manner in at least two angular positions, is characterized in that the retaining element or the eyelet is detachably arranged in the base body with a spring-loaded fastening device or with a magnetic fastening device or with a mechanical fastening device, and that the mechanical fastening device is designed as a wedge and / or as a key and / or as a cone.

[0024] The device according to the invention has the advantage that the at least one eyelet or the retaining element in which the eyelet is arranged can be rotated about its longitudinal axis when a contact surface of the eyelet on an inner diameter of the eyelet has worn down due to the passage of the wire. The at least one eyelet or the retaining element is arranged in the base body in a way that allows it to be fixed in at least two angular positions, so that when a first contact surface of the eyelet wears down, the eyelet or the retaining element with the eyelet is rotated and fixed in a second or further angular position. In this way, the service life of the eyelet can be multiplied. If two angular positions are provided, the service life is doubled. If four angular positions are provided, the service life is quadrupled.

[0025] The device according to the invention has the further advantage that the wires do not need to be cut and removed in order to rotate the eyelets around their longitudinal axis and re-fix them. This means that the production of, for example, a stranded wire is merely stopped. The at least one eyelet or the retaining element with the eyelet is released, rotated by a predetermined angle, and re-fixed. Production can then continue.

[0026] According to the invention, wire is understood to be, for example, a thin and long, flexible material with, for example, a circular cross-section. The material can be, for example, a metal. Other cross-sectional shapes, such as flat, square, or profile cross-sections, can be provided instead of a circular cross-section.

[0027] If the wire is made of metal, it can be made of materials such as iron, copper, brass, aluminum, silver, gold, titanium, or stainless steel, or of alloys, such as a copper alloy. The wire can also be coated with materials such as silver or tin.

[0028] According to the invention, however, wire also includes a plastic wire, for example a polymer monofilament.

[0029] According to the invention, the term "wire" is also understood to include threads or fibers. These threads or fibers can also be made of plastic or metal. The threads or fibers can, for example, be stranded. In the following, the term "wire" is primarily used. However, it always refers equally to wire, thread, fiber, or any other thin and long material.

[0030] The wires, threads, or fibers can also be made of natural materials. For example, they can be made of cotton, silk, or similar materials.

[0031] A combination of materials is also possible.

[0032] According to an advantageous embodiment of the invention, each eyelet is arranged in a retaining element, and the retaining element of the at least one eyelet can be arranged in the base body in at least two angular positions. Advantageously, the eyelet with the retaining element can be fixed in the base body.

[0033] This makes it possible to position the eyelet with the retaining element within the base body. The eyelets can each have the same shape. Only the retaining elements are adapted to the requirements. The retaining elements are designed so that they can be positioned and fixed in the base body at the desired number of angular positions.

[0034] The eyelets can always have the same shape, regardless of the design of the retaining elements.

[0035] The arrangement of the eyelet in a retaining element has the advantage that the eyelet, which is usually circular, can be positioned and fixed in defined angular positions in the base body by the retaining element.

[0036] The eyelets do not need to be arranged in a retaining element. If the eyelets are arranged directly in the base body, they advantageously have a base that deviates from a circle. This allows the eyelets to be arranged in at least two angular positions within the base body without them rotating themselves into a different angular position.

[0037] Advantageously, the base body has at least one receptacle for arranging the eyelet or retaining element. Preferably, a receptacle is provided in the base body for each eyelet or retaining element with eyelet.

[0038] According to the invention, the retaining element or eyelet is detachably arranged in the base body with a spring-loaded fastening device, a magnetic fastening device, or a mechanical fastening device.

[0039] This embodiment has the advantage that the eyelet or the retaining element with the eyelet can be easily detached from the base body, preferably without tools. The eyelet or the retaining element with the eyelet can then be rotated about its longitudinal axis and advantageously reattached to the base body, also without the use of tools.

[0040] In the advantageous embodiment with the spring-loaded fastening device, the eyelet or the retaining element snaps into the base body with the eyelet and is fixed there.

[0041] According to a particularly preferred embodiment of the invention, the spring-loaded fastening device is designed as at least one spring-loaded ball.

[0042] The spring-loaded ball is advantageously arranged within the base body. The eyelet or retaining element with the eyelet has a receptacle, for example, a circumferential groove or recesses or the like, into which the ball can engage. If the eyelet or retaining element with the eyelet is released from the base body, an axially acting force is sufficient to deflect the ball against the spring force out of the groove, recess, or the like. This allows the eyelet or retaining element with the eyelet to be released from the base body.

[0043] It is possible to arrange the ball and spring in a housing, for example, in a cylinder. Advantageously, a cylindrical recess can be formed in this cylinder during the 3D-printing of the base body, in which the cylinder, spring, and ball can be arranged. One or more cylinders with a ball and spring can be provided in a receptacle located in the base body for the eyelet or for the retaining element with the eyelet.

[0044] If at least two cylinders are provided, they are advantageously arranged radially symmetrically in the recess of the base body.

[0045] It is also possible to arrange at least one cylinder with the spring-loaded ball in the eyelet or the retaining element with the eyelet. In this case, a corresponding groove, recess, or similar feature for the engagement of the ball is provided in the base body in the receptacle for the eyelet or for the retaining element with the eyelet.

[0046] Instead of the cylinder, other spring-loaded fastening devices can also be provided. According to another advantageous embodiment, a retaining ring is provided.

[0047] The retaining ring is advantageously arranged in a groove of the base body. When the retaining ring is spread open, the eyelet or retaining element can be positioned in the receptacle. Subsequently, the retaining ring returns to its original shape, advantageously engaging in a groove of the eyelet or retaining element and thus securing it.

[0048] According to another advantageous embodiment of the invention, the spring-loaded fastening device can be designed as an elastic O-ring.

[0049] The O-ring is advantageously arranged in a groove in the base body. When the eyelet or retaining element is inserted axially into the receptacle of the base body, the O-ring yields due to its elasticity. A groove is advantageously provided in the eyelet or retaining element, in which the O-ring is positioned after the eyelet or retaining element is fully inserted into the receptacle. After insertion of the eyelet or retaining element, the O-ring returns to its original shape due to its elasticity, thus securing the eyelet or retaining element.

[0050] According to the invention, the mechanical fastening device is designed as a wedge and / or as a key and / or as a cone.

[0051] This mechanical fastening device can be advantageously manufactured using 3D printing.

[0052] The design as a mechanical fastening device has the advantage of being easy to manufacture. It can be easily disassembled without tools. Attaching the eyelet or retaining element using this fastening device is also straightforward.

[0053] According to a further advantageous embodiment of the invention, a magnetic fastening device is provided. For this purpose, at least one magnet is advantageously arranged in the eyelet or in the retaining element. A force-fit connection can be formed with the base body via the at least one magnet.

[0054] For this purpose, the base body is made, for example, of a ferromagnetic material, such as a metal like iron. It is also possible to arrange a component made of ferromagnetic material within the base body if it is not made of ferromagnetic material. The ferromagnetic component is advantageously located in the area of ​​the receptacle for the eyelet or retaining element and within the magnetic field of the at least one magnet, if the eyelet or retaining element is located in the receptacle. The ferromagnetic component can be, for example, a cylinder, a cube, a cuboid, or the like.

[0055] According to another advantageous embodiment of the invention, the at least one magnet is arranged in the receptacle of the base body, and a component made of a ferromagnetic material is arranged as a counterpart in the eyelet or in the retaining element. According to a further embodiment, the eyelet or the retaining element can be made of ferromagnetic material.

[0056] According to an advantageous embodiment of the invention, the eyelet with the retaining element or the eyelet is designed to be rotatable about a longitudinal axis of the eyelet.

[0057] This design makes it possible to arrange the eyelets in different angular positions in the base body.

[0058] The eyelets or the eyelets with the retaining elements can be rotatably arranged in the base body. However, according to a further embodiment, it is possible to remove the eyelets or the retaining elements from the base body and rearrange them in a different angular position than the previous one. In both cases, the eyelets are rotated about their longitudinal axis. The longitudinal axis corresponds to the axial axis of the eyelet.

[0059] According to a further advantageous embodiment of the invention, it is provided that at least one receptacle is provided in the base body for the arrangement of the at least one retaining element with the eyelet arranged in the retaining element or for the arrangement of the eyelet.

[0060] This embodiment has the advantage that the retaining element of the eyelet or the eyelet itself can be arranged in a corresponding receptacle within the base body. The receptacle and the retaining element are designed such that the retaining element can be arranged in at least two different angular positions within the base body. Likewise, the receptacle and the eyelet can be designed without a retaining element, allowing the eyelet to be arranged in at least two different angular positions within the base body.

[0061] The invention has the advantage that the eyelets or retaining elements with the eyelets can be easily detached from the base body during operation. The wires do not need to be cut for this purpose. The at least one retaining element with the eyelet arranged in the retaining element, or the eyelet itself, is detached from its receptacle in the base body and then rotated by a predetermined angle. Afterwards, the at least one retaining element or the eyelet is reinserted into its receptacle.

[0062] According to a further advantageous embodiment of the invention, it is provided that the at least one retaining element or the eyelet has a cross-sectional profile, and that the base body has at least one receptacle in which the cross-sectional profile of the at least one retaining element or the at least one eyelet can be arranged in a form-fitting and / or force-fitting and / or material-fitting manner.

[0063] A material-bonded connection is characterized by the fact that a component connection is created which, under normal circumstances, can no longer be broken except by destruction.

[0064] As already explained, in the event of local wear of the eyelet, the retaining element or eyelet is rotated by a predetermined angle, for example 90°.

[0065] The retaining element or eyelet advantageously has a cross-sectional profile and the base body has at least one corresponding receptacle in which the cross-sectional profile of the at least one retaining element or eyelet can be arranged in a form-fitting manner.

[0066] The receptacle is designed in such a way that the retaining element or eyelet can be arranged in a form-fitting manner in several angular positions within the receptacle.

[0067] The retaining element or eyelet can also be arranged in the receptacle in a force-fit manner.

[0068] The retaining element or eyelet advantageously has a first cross-sectional profile in the wire feed direction. In the wire exit direction, the retaining element or eyelet advantageously has a second cross-sectional profile. The feed and exit directions can also be reversed with respect to the device.

[0069] The two cross-sectional profiles can be arranged in a form-fitting manner within the base body.

[0070] Both cross-sectional profiles are designed so that the retaining element can be rotated around predetermined angular positions and arranged in the base body in the different angular positions.

[0071] If, for example, the retaining element or the eyelet is to be arranged in the receptacles rotated by 90°, both cross-sectional profiles must be designed in such a way that a 90° rotation and an arrangement of the retaining element or the eyelet in the base body is possible.

[0072] According to an advantageous embodiment of the invention, the cross-sectional profiles are each rotationally symmetrical. Due to this design, it is possible to rotate the at least one retaining element by angles of, for example, 180°, 90°, 60°, 45°, 30° or other angles and to arrange it in the receptacles of the base body.

[0073] According to a further advantageous embodiment of the invention, it is provided that the at least one eyelet is glued and / or screwed and / or pressed in and / or clamped in an annular groove of the retaining element.

[0074] The eyelets are advantageously arranged firmly in the retaining element.

[0075] The secure connection between the eyelet and the retaining element can be created by gluing and / or screwing and / or pressing in and / or with a clamping connection.

[0076] Other fixed connections are also possible.

[0077] It is also possible to use a combination of fastening methods. For example, the eyelet can be screwed into the mounting element and fixed with adhesive.

[0078] Another advantageous embodiment of the device according to the invention provides that the at least one retaining element and / or the at least one eyelet in the retaining element or an eyelet without a retaining element is formed flush with an outer surface of the base body.

[0079] If the retaining element and / or at least one eyelet is flush with the outer surface of the base body, the wires are guided through the eyelets without contacting the base body, thus preventing unwanted contact with the base body. Such contact could damage the wire.

[0080] Another advantageous embodiment of the invention provides that the at least one retaining element of the at least one eyelet or the eyelet has at least one marking to indicate the angular position of the retaining element or the eyelet in the base body.

[0081] The marking has the advantage that, when multiple retaining elements or eyelets are used, it is easy to identify which retaining elements or eyelets have been rotated by a predetermined angular position. The marking also makes it easy to ensure that all retaining elements or eyelets have been rotated by the same angular position and the same number of times as the other retaining elements or eyelets.

[0082] Another advantageous embodiment of the invention provides that the at least one retaining element of the at least one eyelet or the at least one eyelet is rotatably arranged in the base body.

[0083] If a large number of eyelets are arranged in the base body, it is advantageous to twist at least two of the retaining elements or eyelets, or all of them together. It is particularly advantageous to twist all of the retaining elements or eyelets together.

[0084] This design minimizes the effort required to rotate the retaining elements or eyelets. Furthermore, all retaining elements or eyelets are aligned in the same direction. Additionally, much finer angular positions can be set using a motor, and the entire inner circumference of the eyelets can be utilized.

[0085] Advantageously, a gear is provided for rotating the at least one retaining element of the at least one eyelet or for rotating the at least one eyelet in the base body.

[0086] This training makes it possible, especially when a large number of retaining elements or eyelets are provided, to twist all retaining elements or eyelets simultaneously.

[0087] The twisting of the retaining elements or eyelets can be done manually or by motor.

[0088] The transmission can consist of a mechanism made up of gears. For example, the gears can be bevel or spur gears. Racks or worm gears can also be used. A planetary gear system is another possibility.

[0089] According to a further advantageous embodiment, at least one eyelet is made of ceramic.

[0090] The eyelets can be made of materials such as oxide ceramics, nitride ceramics, or carbide ceramics. They can also be made of hard metals or coated metals.

[0091] If the eyelets are made of oxide ceramics, they can be formed from aluminum oxide, zirconium oxide, or titanium oxide. If the eyelets are made of nitride ceramics, they can be made of silicon nitride. If the eyelets are made of carbide ceramics, they can be made of silicon carbide.

[0092] If hard metals are used as materials for the eyelets, tungsten carbide, for example, can be used.

[0093] Another advantageous embodiment of the invention provides that the at least one retaining element and / or the base body are made of a plastic and / or metal.

[0094] The retaining element and / or the base body can be made of, for example, thermoplastic materials such as polylactic acid (PLA), acrylonitrile butadiene styrene copolymer (ABS), acrylonitrile styrene acrylate (ASA), or a composite material such as nylon and polyamide (PA). The retaining element and / or the base body can also be made of a resin, such as synthetic or natural resins, which can be UV-cured. Alternatively, the retaining element and / or the base body can be made of a coated plastic. The coating could be, for example, a resin or lacquer.

[0095] In principle, it is also possible to provide composite solutions for the brackets and / or the base body.

[0096] The retaining element or the base body can also be made of metal, for example steel.

[0097] The base body can also be made of ceramic.

[0098] Another advantageous embodiment of the invention provides that the device is arranged in a device for producing stranded wires and / or in a wire drawing machine. The device for guiding at least one wire is particularly advantageously arranged in a device for producing stranded wires, in which a plurality of wires are generally fed, or, for example, in a wire drawing machine, in which wires are also fed and deflected.

[0099] The present invention may also relate to other machines, for example in the textile industry.

[0101] Fig. 1Figure 1 shows, schematically only, a device 1 for guiding several wires 2, 3, 4. The wires 2, 3, 4 are fed from wire coils 8 through the device 1 to a device 5 for producing a stranded wire. The stranded wire is in Fig. 1 not shown.

[0102] Device 1 is also called Verlitzstern.

[0103] For example, a device 5 for producing the strand has a rotating bracket, so that a strand can be produced from at least two wires 2, 3, 4.

[0104] Fig. 2 The device 1 for guiding the wires is shown. Fig. 2 Only wires 2 and 3 are shown. The device 1 has a base body 6 in which eyelets 7, for example made of a ceramic material, are arranged. The device 1 has a foot 9 which is fixed to a rod 10. The device 1 can be interchangeably positioned on the rod 10. Fig. 2 The basic body 6 is shown only schematically with the eyelets 7.

[0105] Fig. 3 Figure 1 shows the device with the base body 6 and the foot 9. A plurality of through-holes 12 are arranged in the base body 6 for the passage of the wires 2, 3, 4 (in the Fig. 3 (not shown).

[0106] The base body is arranged in the foot 9. The connection between the base body 6 and the foot 9 is also a detachable connection.

[0107] According to the Figs. 4 to 8 The base body has 6 receptacles 13 for retaining elements 14 of eyelets 7, which are located in the Figs. 9 to 11 are shown. The basic body 6 has a multitude of recesses 13. The recesses 13 have setbacks 18 into which projections 17 of the retaining element 14 engage. Through the in Fig. 7In the four recesses 18 shown, a retaining element 14 can be arranged in the receptacles 13 in four different angular positions, each rotated by 90°.

[0108] The Figs. 9 to 11 Figure 14 shows a retaining element 14 in which an eyelet 7 is arranged. The retaining element 14 has three projections 17 which can be arranged in the recesses 18 of the receptacles 13. In the Fig. 9 No projection is provided at the 6 o'clock position shown. This serves as a marker indicating the rotational angle position of the retaining element 14 in the receptacle 13.

[0109] The retaining element 14 has a first cross-sectional profile 15, which is designed as a flange. The projections 17 are arranged on the flange.

[0110] A circumferential groove 40 is arranged in a second cross-sectional profile 16. A ball 41 can engage in this groove.

[0111] The eyelets 7 are glued and / or screwed and / or pressed into the retaining elements 14 and / or clamped in a ring groove of the retaining element 14.

[0112] The retaining elements 14 with the eyelets 7 are fixed in the base body 6 by various fastening devices. These fastening devices are described in detail below. The receptacles 13 have a cross-sectional shape that corresponds to a cross-sectional shape of the retaining elements 14 associated with the base body 6. The retaining elements 14 are arranged in the receptacles 13 in a form-fitting manner.

[0113] As in Fig. 12 The ball 41 is shown to be spring-mounted in a bore 43 by means of a spring 42.

[0114] When the retaining element 14 is positioned in the receptacle 13, the spring 42 presses the ball 41 radially into the groove 40 of the eyelet 7. This secures the retaining element 14 in the receptacle 13 by friction.

[0115] The recesses 18 of the receptacles 13, the projections 17 of the retaining elements 14, the first cross-sectional profile 15 of the retaining element 14 and the receptacle 13 adapted to the cross-sectional profile 15 create a positive fit between the retaining element 14 and the receptacle 13.

[0116] Fig. 13 The image 13 shows the base body 6. An O-ring 44 is arranged in the image 13.

[0117] Fig. 14 The retaining element 14 shows how in the Figs. 9 to 11 described. An O-ring 44 is arranged in the groove 40. The O-ring 44 can be arranged in the receptacle 13 of the base body 6, as described in Fig. 13 The O-ring 44 can also be arranged on the retaining element 14, as shown in Fig. 13 As shown. When the retaining element 14 is positioned in the receptacle 13, the O-ring 44 forms a force-fit fastening device between the retaining element 14 and the receptacle 13.

[0118] The retaining element 14 can be rotated around the longitudinal axis L with the eyelet 7.

[0119] Instead of the O-ring 44, a retaining ring 45, as shown in Fig. 15 The retaining ring 45 is provided as a fastening device. It is arranged in the bore 43 (not shown) of the receptacle 13 and engages in the groove 40 of the retaining element 14.

[0120] According to Fig. 16 The retaining element 14 has a conically tapered cross-sectional profile 16. The receptacle 13 has a correspondingly tapered cross-sectional profile (not shown), so that the retaining element 14 can be arranged in the receptacle 13 in a form-fit and force-fit manner. As shown in Fig. 16The wire guide direction is shown in the direction of arrow A. This presses the retaining element 14, with its cross-sectional profile 16 tapering in the direction of the wire guide, into the receptacle 13 in the direction of arrow A and holds it there. This creates a frictional connection. The retaining element 14 can also be pressed into the receptacle 13 by another external force, which also creates a frictional connection.

[0121] Fig. 17 Figure 1 shows a modified embodiment of a retaining element 14. At least one magnet 46 is arranged on an outer circumference of the retaining element 14. The magnet 46 can be designed as a circumferential ring. However, it is also possible to use a second magnet 47, as shown in Figure 1. Fig. 17 As shown, to be provided. In principle, a magnet 46 is also sufficient.

[0122] If the base body 6 is made of a ferromagnetic material, for example metal, the retaining element 14 is held in the receptacle 13 by means of the magnet 46 and / or 47. If the base body 6 is not made of a metallic material, a metallic body can be arranged in the receptacle 13.

[0123] Fig. 18 Figure 1 shows the base body 6 with the receptacle 13, in which a metal body 48 is arranged in the bore 43. A magnet 49 can also be arranged in the receptacle 13. In this case, a metal body 50 is arranged in the retaining element in the groove 40.

[0124] According to Fig. 19 The retaining element 14 has two different cross-sectional profiles 15, 16.

[0125] Cross-sectional profile 16 is designed as a square cross-sectional profile. Cross-sectional profile 15 has projections 17. Both cross-sectional profile 15 and cross-sectional profile 16 are rotationally symmetrical.

[0126] According to Fig. 19 The retaining element 14 has two different cross-sectional profiles 15, 16 in the axial direction.

[0127] The retaining elements 14 are arranged in the receptacles 13 with the cross-sectional profiles 15, 16 in a form-fitting manner.

[0128] As in Fig. 19 The eyelet 7 and the retaining element 14 are shown to have a longitudinal axis L. The retaining element 14 can be arranged in different angular positions in the base body 6 around this longitudinal axis L.

[0129] The Figs. 20 to 22 show the retaining element 14 with the eyelet 7 arranged in the retaining element 14.

[0130] The wires 2, 3, 4 typically only run along a single point of contact or a narrow contact area of ​​the eyelet 7 during manufacturing. Fig. 7 Wire 2 is shown only schematically. Is wire 2 located in the Fig. 20At the position shown on eyelet 7, eyelet 7 experiences particularly heavy wear at this point.

[0131] If the signs of wear are so extensive that proper guidance of the wire 2 is no longer guaranteed, the eyelet 7 with the retaining element 14 is removed from the receptacle 13, rotated by 90° and placed back in the receptacle 13. The projections 17, which are arranged in the recesses 18 of the receptacle 13, define an angular position of the retaining element 14 in the base body 6.

[0132] After rotation, wire 2 rests against a point on eyelet 7 that previously had little or no contact with the wire. This significantly extends the service life of eyelet 7. The [unclear text] Figs. 19 to 22 The depicted retaining elements 14 allow four different angular positions, as four projections 17 are provided.

[0133] In principle, it is also possible to provide more or fewer projections 17. The recordings 13 then have a corresponding number of retractions 18.

[0134] It is essential that the retaining element 14 has a rotationally symmetrical cross-sectional profile.

[0135] As in Fig. 19 As shown, the eyelet 7 is designed to widen conically. The wires 2, 3, 4 are often not fed into the eyelet 7 parallel to its longitudinal axis L, but at an angle to it. The conical shape of the eyelet 7 reduces the mechanical stress on the wires 2, 3, 4.

[0136] According to Fig. 20 The retaining element 14 has a marking 19. Is the marking 19 in the Fig. 20With the orientation shown in Figure 6 at the top, a user can see that the retaining element 14 is, for example, in a first position. If the retaining element 14 is rotated by 90°, the marker 19 also moves by 90°. If these markers are provided on all elements 14, a user can see which retaining elements 14 are rotated and which are not.

[0137] As in Fig. 22 As shown, the retaining element 14 has four projections 17 which engage in corresponding recesses 18 of the receptacle 13.

[0138] The Figs. 23 to 25Figure 1 shows a modified embodiment of a bracket 14. The bracket 14 has a triangular cross-sectional profile 16 with rounded corners. The cross-sectional profile 15 of the bracket 14 has three projections 17. The projections 17 are arranged in corresponding recesses of the base body 6 (not shown). This bracket 14 can be rotated by 120°. The bracket 14 can be arranged in three angular positions. This triples the service life of the eyelet.

[0139] The bracket 14 also has a marking 19, which is designed as a groove.

[0140] The Figs. 26 to 28Figure 1 shows a further modified embodiment of a bracket 14. The bracket has a hexagonal cross-sectional profile 16. The cross-sectional profile 15 of the bracket 14 has six projections 17. The projections 17 are arranged in corresponding recesses of the base body 6 (not shown). This bracket 14 can be rotated by 60°. The bracket 14 can be arranged in six angular positions. This increases the service life of the eyelet sixfold.

[0141] The retaining element 14 also has a marking 19, which is designed as a groove.

[0142] Fig. 29 Figure 21 shows a planetary gear set with which all retaining elements 14, 14', 14" can be rotated. The drive is, for example, motorized. A manual drive can also be provided.

[0143] A drive ring 22 has an inner gear ring 23 which engages with gear rings 24 arranged on the retaining elements 14.

[0144] The retaining element 14' is rotated via the retaining element 14". The retaining elements 14, 14', 14" are freely rotatable within the base body 6 (not shown). The retaining elements 14, 14', 14" are fixed during operation, i.e., when the wires are inserted, by means of the planetary gear 21.

[0145] The retaining elements 14, 14', 14" can be fixed in any angular position.

[0146] The Figs. 30 to 32 Figure 23 shows an eyelet 23 that is not arranged in a retaining element. The eyelet 23 has a cross-sectional profile 24. The eyelet 23 has a base that is square.

[0147] The eyelet 23 is arranged directly in the base body 6 without being arranged in a holding element.

[0148] Due to the square shape of the base of the eyelet 23, the eyelet 23 can be arranged in the base body 6 in four different angular positions.

[0149] The base can also be shaped differently than a square. For example, if the base is shaped as an equilateral triangle (not shown), the eyelet 23 can be arranged in three different angular positions in a base body with corresponding triangular-shaped receptacles in cross-section.

[0150] The Figures 33 to 35 Figure 25 shows eyelet 25. Eyelet 25 has a substantially square base. One corner 26 of eyelet 25 is truncated, creating a marking. The position of this marking indicates whether all eyelets 25 are arranged at the same angle or at different angles, i.e., in this case, rotated by 90° each.

[0151] The eyelet 25 has a circumferential groove 27.

[0152] The Figures 36 to 38 Figure 1 shows an eyelet 28. The eyelet 28 has an essentially square base. One corner 29 is rounded. This corner 29 serves as a marker to check the angular positions of the individual eyelets 28.

[0153] The eyelet 28 also has a circumferential groove 30.

[0154] The Figs. 39 to 41 Figure 31 shows an eyelet 31. The eyelet 31 has a square base. The eyelet 31 has a notch 32. The notch 32 also serves as a marker for checking the angular position of the eyelet 31. The eyelet 31 also has a circumferential groove 33.

[0155] The Figs. 42 and 43 Figure 36 shows an eyelet with a square cross-section. This eyelet can be rotated by 90° in each direction.

[0156] The Figs. 44 and 45 The figures show an eyelet 37 with a pentagonal base. This eyelet 37 can be rotated by 72° in each direction.

[0157] The Figs. 46 and 47 Figure 1 shows an eyelet 38 with a hexagonal base. This eyelet can be rotated by 60° each time, so that it can be arranged in six angular positions in the base body 6 and the mounting plate 11.

[0158] All eyelets 7, 23, 25, 28, 31, 36, 37, 38 have a through-hole 39 for one or more wires.

[0159] All embodiments shown or mentioned can be designed individually or combined with one another without leaving the scope of protection of the following claims. Reference figures
