    “CHATO ENERGIA CABLE” [1] The invention relates to a flat electrical cable according to the preamble of claim 1.
    [2] The purpose of such flat cables is to conduct at least one core - comprising an electrical conductor isolated by an insulating layer - and, optionally, telecommunication conductors - such as optical fibers - and / or fluid ducts - for example, to transport oil, gas, or water - from supply equipment to a device, for example, a mobile machine. In the present description, optional telecommunication conductors and fluid ducts could be collectively referred to as "lines".
    [3] The flat electric cable is provided with a sheath protecting the at least one core and the optional nails against external influences. On mobile devices, specially designed to perform movements over a large area, the flat cable is divided into an upper portion of an upper length and a portion of a lower length. The lower length portion is arranged on a distribution chute on a distribution surface, while the upper length portion is connected to the lower length portion by means of a folding section. Thus, there is the advantage, compared to a cable guide in a power supply chain, that such a flat cable device is easier and cheaper to manufacture. However, a flat cable does not have the same stability as a power supply chain and is therefore not as resistant to wear. In addition, there is the disadvantage that, compared to a power supply chain, considering the flexibility of the cable, excessive bending in the folding section can occur, endangering the integrity of the cable and possibly causing the two to slip. longitudinal sections, one in contact with another, causing additional friction damage.
    Petition 870190000029, of 01/02/2019, p. 13/32
    2/15 [4] Therefore, it is a problem faced by the invention to develop a flat electric cable in such a way that it has increased stability and resistance to wear.
    [5] Another problem to be considered is the forces of repulsion and attraction, sometimes abruptly, by the mobile device. These forces can endanger the integrity of the cable and shorten its useful life. In the case of repulsion forces, a specific phenomenon called "warping" can occur.
    [6] US 2007/0144376 refers to a device for guiding at least one line that protects it, in the distribution chute, so as to be guided, at least partially, without contact. The cable is surrounded by a sheath, on whose bottom side, facing the distribution surface, a distribution surface magnet is disposed. Facing the magnet on the underside, a distribution surface magnet is disposed on the distribution surface. As a result, the sheath, with the cable wrapped around it, is kept suspended above the distribution surface. The cable is guided by a device carrying magnets. No words are provided about the repulsion / attraction forces exerted on the cable and how to remedy the related problems.
    [7] US 6,405,843 refers to a flat, self-supporting electrical cable, especially for use in linear motion devices. The cable is in the form of a strip with a crowned or curved cross section. The band is self-supporting and is typically used in a loop set. The strip is composed of a Mylar or other plastic or electrically insulating laminate with electrical conductors and reinforcement elements. The reinforcement elements are typically stainless steel. In use, the cable is normally turned over itself by 180 ° to provide a loop configuration with a fixed loop radius where the loop is movable along the direction of travel.
    [8] The cable does not comprise magnetic parts. The feature of
    Petition 870190000029, of 01/02/2019, p. 14/32
    3/15 Self-support is provided by a curved configuration of the cable surface and by the strip over the cable surface. No word is given about the repulsion / traction risk forces exerted on the cable.
    [9] US 6,215,068 refers to a line guide assembly. The line embedding means has on its external side a sliding means as a good sliding capacity. The sliding means prevents friction between an upper length portion and a lower length portion of a set of lines. The thread embedding means may comprise staples and thread spaced in the longitudinal direction of the thread assembly, as the sliding means being disposed on the outside of said thread clamps. The sliding medium consists of a flexurally elastic material, such as steel, or a sliding plastic material, such as polyurethane, polyamide and polytetrafluoroethylene. The sliding medium, then, not only forms a mechanical sliding protection for the cable jacket, but is adapted to maintain the pulling and repelling forces exerted during the reciprocation of the moving honeys, outside the set of lines. When the longitudinal ends of the sliding medium are coupled in such a way to the stationary and mobile means, respectively, a strain relief for the set of lines is also established.
    [10] The set does not include magnetic parts. The cable of the set does not have specific reinforcement elements to protect the cable against forces of attraction and repulsion exerted on it.
    [11] JP 06-078439 refers to a power supply device for a moving part, where a permanent magnet is provided on the side of the moving part in order to prevent the formation of meanders from a flat cable. The cable assembly, moving in a guide box provided with a permanent magnet plate, comprises a flat cable and a magnetic plate positioned on the cable surface inside the loop. Optionally, a ribbon-shaped guide (a resin ribbon) is provided on the cable surface
    Petition 870190000029, of 01/02/2019, p. 15/32
    4/15 facing the guide box to reduce friction.
    [12] The cable is moved on a guide device. The magnet provided with the cable operates with the permanent magnet of the guide device. No words are provided about the repulsion / attraction forces exerted on the cable and how to remedy the related problem.
    [13] The invention provides a flat electrical cable comprising at least one core and at least one sheath provided in a radially external position with respect to said core, comprising:
    - at least one push-pull resistance member extending substantially parallel to at least one core;
    - a connection system connected to the outer surface of the sheath;
    - a plurality of magnets connected to the connection system, the mentioned magnets having parallel magnetic axes commonly guided, directed at right angles to the surface of the sheath.
    [14] Other advantageous developments are subject to subordinate claims.
    [15] The idea behind the invention is the fact that the member of symmetrical intensity provides the flat electrical cable with sufficient rigidity to counteract the phenomenon of wrinkling and adequate tensile strength.
    [16] Advantageously, the member of symmetrical intensity has a design and is made of material adapted to relieve the cable structure, especially the cores, from mechanical forces communicated to the cable by the moving parts, in particular, with a mobile device.
    [17] By providing the flat electrical cable with a plurality of magnets via a connection system with magnetic poles of the same polarity pointing opposite to an upper surface of the sheath, friction and thus wear is reduced when a portion of the cable's upper length
    Petition 870190000029, of 01/02/2019, p. 16/32
    Electric boring 5/15 is moved over the top of lower length portion. It is also possible to keep the upper length portion suspended over the lower length portion, thus reducing friction to a minimum.
    [18] It is preferred that the connection system comprises at least one longitudinal groove, provided on the outer surface of the sheath or in a strip coupled on the outer surface of the sheath. In particular, it is advantageous that the connection system comprises at least two longitudinal grooves arranged on opposite sides of the cable. More preferably, the connection system comprises at least the pairs of longitudinal grooves arranged on opposite sides of the cable.
    [19] The groove or grooves advantageously serve to operationally associate, for example, securing, a plurality of clips to the sheath or the strip. Preferably, the clips being arranged in a row, one after the other, in the longitudinal direction of the flat electrical cable. On the one hand, the clips can help to stiffen the flat electrical cable into sections by forming essentially inflexible sections. In this way, a radius of curvature is defined, which is approximately constant for the entire flat electrical cable, if the clips are arranged at approximately constant intervals from each other. On the other hand, the clips can accommodate the magnets.
    [20] According to a preferred embodiment, the at least one push-pull resistance member is arranged with an axis positioned on a neutral cable folding plane. The neutral folding plane is a plane substantially parallel to the longitudinal direction of the cable in which the cable does not change or only slightly changes its length when being folded.
    [21] Preferably, the at least one pusher-resistant member comprises a central traction support element surrounded by a containment layer. Such a composite design provides the strength member with sufficient tensile strength due to the supporting element
    Petition 870190000029, of 01/02/2019, p. 17/32
    6/15 traction also with sufficient stiffness due to the containment layer. For this purpose, it is preferred that the central traction support element is made of fibrous material selected from aromatic polyamide fibers, carbon fibers, high modulus fibers or a combination thereof. Examples of high modulus fibers are polyamide fibers and aromatic polyamide (aramid) fibers.
    [22] A push-pull resistance member made of glass-reinforced fiber rods (GRP) was tested with negative results: it broke after a number of bending cycles representative of the application in the pressure chamber. This confirms that it is not obvious to design a tensile strength member that is flexible enough to survive repeated bending.
    [23] Preferably, the containment layer comprises an elastomeric layer, for example, comprising a rubber material, such as ethylene-propylene rubber (EPR).
    [24] According to the preferred embodiment, the containment layer comprises two layers, preferably including a shell made of a polymeric material such as pliamide resin, polybutylene, polytetrafluoroethylene. The elastomeric layer has a smaller flexural modulus than that of the shell material. Advantageously, the shell surrounds the elastomeric layer.
    [25] Advantageously, the strip attached to the outer surface of the cable sheath is made of substantially the same polymer material as the sheath, for example, a material belonging to the same family of polymers.
    [26] Optionally, the sheath comprises an inner sheath portion in which the at least one core is embedded and an outer sheath portion surrounding the inner sheath portion.
    [27] Advantageously, a pattern of reinforcement wires or elements
    Petition 870190000029, of 01/02/2019, p. 18/32 / 15 of reinforcement in the longitudinal direction is arranged between the inner and outer sheath in at least a portion. Reinforcement wires or reinforcement elements can also increase the stiffness and tensile strength of the flat electrical cable. For example, reinforcement yarns are made of high modulus fibers, such as polyamide fibers, aromatic polyamide fibers (aramid), carbon fibers, regenerated cellulose fibers (Rayon). For example, the reinforcement elements are made of high modulus fibers, such as polyamide fibers, aromatic polyamide fibers, carbon fibers.
    [28] If the flat electrical cable is provided with a plurality of longitudinal grooves, it is preferred that the grooves are arranged symmetrically with respect to the neutral bending plane and, preferably, symmetrically with respect to a plane perpendicular to the neutral bending plane. Furthermore, according to an advantageous embodiment, at least some of the clips are guided by the groove or grooves to be able to move in the longitudinal direction of the sheath.
    [29] According to a preferred embodiment, a spacer is arranged between two adjacent clips in the row, respectively. Spacers prevent relative movement of the clips or limit such movement. It is possible for the spacers to connect two adjacent clips, respectively, preferably being elastically foldable. Especially, it is possible that the spacer is a helical clip. However, it is also possible for the spacer to comprise a first portion connected to the first clip, a second portion connected to a second clip and a joint connecting the first and second portions, to enable the flat electrical cable to form the folding section between the portion upper and lower length. It is also possible that the spacer comprises a first spacer element connected to a first clip and a second spacer element connected to a second clip, respectively, where the first spacer element is positioned at
    Petition 870190000029, of 01/02/2019, p. 19/32
    8/15 a distance from the second spacer element. In this embodiment, the adjacent clips are not connected to each other, but a minimum distance between the clips is obtained due to the spacer.
    [30] Advantageously, the flat electrical cable according to the invention can contain at least one additional conductor accommodated in at least one sheath, for example, selected from telecommunication conductor, optical conductor, copper pair, control conductor and duct fluid to conduct, for example, water, oils, lubricants, air, compressed air. In the case of an optical conductor, at least one optical fiber is advantageously protected by the polymeric layers surrounding each glass core, both individually and collectively.
    [31] The at least one core and at least one of the additional conductors can run substantially parallel to the longitudinal axis of the cable or can be twisted. The at least one core and the at least one of the optional additional conductors can be provided with their axis arranged in the neutral folding plane of the cable or arranged in an upper or lower plane with respect to said folding plane. For example, a plurality of copper pairs can be provided to surround a pull-push member.
    [32] In another embodiment, several clips, preferably rigid, are posted prominently, spaced apart, in at least one bundle of lines in their longitudinal direction. In this case, a rigid clip should be understood as being a clip which, in the longitudinal direction of the line pack, is not flexible or is only slightly flexible and, as a result, stiffens the line pack by its length. In this case, it is preferred that the clips are arranged and fixed intervals from each other.
    [33] The idea behind the invention is that at least one bundle of lines is stiffened into sections by means of clips and, thus, sections are formed being essentially inflexible. In this way, a radius of
    Petition 870190000029, of 01/02/2019, p. 20/32
    9/15 curvature is defined, being constant for the entire line guiding device, if the clips are arranged and fixed intervals from each other.
    [34] It is particularly preferred that the line guiding device has at least two line bundles that run parallel to each other, in which case each line bundle has at least one flexible line wrapped in a flexible cover and where the bundles of line are connected to each other by means of several clips, preferably rigid, arranged at a distance from each other in the longitudinal direction. In this way, the clips serve not only to stiffen the line bundles in sections, but also to interconnect several line bundles that run parallel to each other. In particular, flat cables, which run close to each other, can be connected to each other so that they can be handled as a single flat cable. In this case, it is preferred that the line packages are structurally the same.
    [35] In order to obtain a reliable fixation of the clips, it is preferred that they surround, at least partially, at least one of the line packages. In order to better define the radius of curvature, sequential clips in the longitudinal direction can be connected together so that they can rotate towards each other, preferably to a limited degree.
    [36] The clips are advantageously affixed to at least one of the thread bundles by means of a tongue and groove joint. In this khan, it is preferred that at least one of the line packages has, at least partially, a longitudinally running groove. The groove can be molded on the cover or, alternatively, a strip, on which the groove is molded, can be connected to the cover. The strip can be extruded together with the cover or be firmly glued to the cover.
    [37] According to another advantageous development of the invention, the clips each have at least one magnet, in which case the magnets are arranged so that the magnetic poles of the same name point
    Petition 870190000029, of 01/02/2019, p. 21/32
    10/15 as opposed to an upper surface of the line pack or line packs. If the line pack is folded as an energy supply chain, so that an upper stringer is arranged over a lower stringer, by bundling the repelling forces line of the magnets, the upper stringer can be held suspended above the bottom stringer. The non-contact guide reduces wear. The magnets can advantageously be kept in accommodation openings in the clips or affixed to the outside of the relevant clip.
    [38] According to an advantageous embodiment, the clips are in one piece. Attachment to the cable bundle can occur through elastic deformation of the clips and locking on the cable bundle. According to another advantageous embodiment, the clips are made up of several parts which are detachable from one another.
    [39] Preferably, at least one line pack has a spring steel rope embedded in the cover, which runs parallel to at least one cable. The spring steel rope stiffens the line pack, but nevertheless allows the line pack to be folded. In this case, it is possible for the clips to grab at least one bundle of thread and be attached to the spring steel rope. As a result, the clips are attached to the most resilient components of the line pack.
    [40] In the following, the invention will be explained in more detail by means of exemplary embodiments shown schematically in the drawings, in which:
    [41] Figure 1 is a line guide device comprising a cable of the invention according to a first exemplary embodiment;
    Figure 2 is a section of Figure 1 with the clip removed;
    Figure 3 is a line guide device comprising a cable of the invention according to a second embodiment
    Petition 870190000029, of 01/02/2019, p. 22/32
    Exemplary 11/15;
    Figure 4 is a cross section of a length portion of the line guide device of Figure 3;
    Figure 5 is a cross-sectional view of a flat electrical cable according to an embodiment of the invention;
    Figures 6a, 6b are a cross-sectional view of a flat electrical cable in accordance with other embodiments of the invention;
    Figure 7 is a schematic view of a cable curve according to a third embodiment, and
    Figures 8a to 8c are schematic views of two adjacent clips with different spacers.
    [42] A line guide device 10 (figures 1, 2) comprises a flat electrical cable 12 according to an exemplary embodiment. The flat electric cable 12 has three cores 14 located next to each other, which are embedded in a sheath 16, and run parallel in the longitudinal direction of the first electric cable 12. A strip 18 extending the entire length of the flat cable 12 is placed on sheath 16 and firmly coupled to sheath 16 by means of vulcanization. Lane 18 has two slots 20 which run parallel in the longitudinal direction. In figure 11, it can be seen that the flat electric cable 12 is folded so as to have a portion of lower length 22, a folding section 24 connected to the portion of lower length 22 and a portion of upper length 26 connected to the folding section 24, in which case the upper length portion 26 can be arranged over the lower length portion 22. In this case, the flat electrical cable 12 can serve as a supply cable that connects power supply equipment to a mobile machine.
    [43] Several single-piece clips 28 can be locked onto the flat electrical cable 12. One of these clips 28 is shown in figures 1 and 2. Clip 28 has a receiver contour 30 for partial cable wrapping.
    Petition 870190000029, of 01/02/2019, p. 23/32
    12/15 flat electric 12, from which a tongue 32 protrudes in order to fit into the groove 20 and to form a tongue-and-groove joint. By means of elastic folding, the clip 28 can be attached to the flat electric cable 12. Since it is essentially rigid in the longitudinal direction, the arrangement of the clips 28 on the flat electric cable 12 produces a sectional stiffening of the flat electric cable 12. In this case, clips 28 are preferably attached to the electrical cable 12 at regular intervals from each other. When the flat electric cable is in use, the clips 28 can move in the longitudinal direction, the tongues 32 being guided in the groove 20. The sectional stiffening of the flat cable 12 results in better handling, since it defines the radius of curvature.
    [44] The line guide device 110 (figures 3 and 4) houses two power cables 112 according to another exemplary embodiment, the mentioned cable 112 having a sheath 116 and cores 114 embedded in sheath 116. Different from the first exemplary embodiment, the grooves 120 are, however, molded directly into the sheaths 116. The tongues 132 of two different types of clips 128, 129 fit into the grooves 120. Outer clips 128 surround an outer part of one of both cables power 112. Internal clips 129 arranged between the flat power cables 112 surround a portion of both flat power cables 112 and, as a result, connect the power cables 112 which run parallel to each other. In this case, the clips are designed in two parts. Both parts of the 1434 clips are screwed together.
    [45] A folding section 124, to which, in turn, an upper length portion 126 is connected, connects to a lower length portion 122 of the flat cables 112 that are connected together. In order to reduce wear, clips 128, 129 have accommodation openings 136 on the upper side of the lower length portion 122 and the lower side of the upper length portion 126, where magnets 136 are placed
    Petition 870190000029, of 01/02/2019, p. 24/32
    13/15 so that the magnetic poles of the upper length portion are opposite the poles of the same name as the lower length portion 122. In this way, the upper length portion 126 is kept suspended above the lower length portion 122. If the flat cables 112 are arranged on a flat floor without bending, the magnetic axes of the magnets 138 are arranged substantially parallel to each other and perpendicular to the upper surfaces of the sheaths 116. The clips 28 of figures 1 and 2 can be equipped in the same way.
    [46] Figure 5 shows a cross section of a flat electrical cable of the invention, which can be used with the line guide devices according to figures 1 to 4. Flat cable 212 comprises three cores 214, each of which cores 214 comprising an electrical conductor 240, for example, a copper conductor formed by a bundle of zinc or pure copper electrical wires braided according to conventional methods. Conductors 240 are surrounded by an internal semiconductor layer 242, which is surrounded by an insulating layer 244, which is surrounded by an external semiconductor layer 246. Cores 214 run parallel to each other in a longitudinal direction of the flat electrical cable 212. O flat electrical cable 212 further comprises a push-pull resistance member 250, which extends parallel to the cores 214 over the entire length of the flat electrical cable 212. The resistance member 250 comprises a centrally pulling support element 252 which is surrounded by a containment layer comprising an inner elastomeric layer 254 and an outer shell 256 made, for example, of a polyamide material. The central support element 252 made, for example, of aromatic polyamide, is positioned with its axis 258 in a neutral folding plane 260 of the flat electric cable 212. The cores 214 and the resistance member 250 are accommodated in a sheath portion outer 216 which has a rectangular cross section with rounded corners. Sheath 216 is made of cured polymeric material,
    Petition 870190000029, of 01/02/2019, p. 25/32
    14/15 for example, reinforced heavy-duty heat-curable elastomer, such as high density polyethylene (HDPE), polychloroprene, polyurethane, or NBR-based compound. The space between cores 214, the resistance member 250 and the outer sheath portion 216 is loaded with an inner sheath portion 262 made of a polymeric material, which is extruded directly onto the longitudinal structural elements 214, 216, 250 of the cable flat electric 212. The sheath 216 is provided on its upper and lower outer sides 264 with a pair of slots 220, respectively. The grooves 220 are positioned symmetrically with respect to the neutral folding plane 260 and with respect to a plane perpendicular to the neutral folding plane 260.
    [47] The methods of making flat electrical cables according to figures 6a, 6b comprise reinforcement wires 270 and reinforcement elements 272, respectively, both running parallel to cores 214 and resistance members 250 and positioned between the outer sheath portion 216 and inner sheath portion 262. In these embodiments, four cores 214 are positioned in the middle of the flat electrical cable 212, where, on the left and right of the cores 214, a push-pull resistance member is positioned 250, respectively.
    [48] Although core 214 and resistance member 250 in the embodiments shown are positioned side by side, it is also possible to arrange cores 214 around one or more resistance members 250. The same applies to additional conductors possibly present in the flat electrical cable of the invention.
    [49] Figure 7 shows a side view of the folding section 24, 124 of a flat electrical cable 12, 112, provided with clips 28, 128, as shown in figures 1 to 4. Between two adjacent clips 28, 128, it is a spacer 280 is positioned, respectively, with its axis in the neutral folding plane of the flat electric cable 12, 112. The spacer holds the clips
    Petition 870190000029, of 01/02/2019, p. 26/32
    Adjacent 15/15 28, 128 at a minimum distance from each other. It can be an elastically collapsible bar, as shown in figure 7 or a helical spring 282, as shown in figure 8a. It may also comprise a first portion 284 and a second portion 286 with a hinge 288 connecting to each other. The hinge can be of a type in which the first and second portions 284, 286 are foldably connected, or, as shown in figure 8b, of a type in which the first and second portions 284, 286 can be separated. It is also possible that the spacer comprises a first spacer element 290 and a second spacer element 292, as shown in figure 8c, the spacer elements 290, 292 being positioned at a distance between them.
