Woven electronic device cable, braiding machine for woven electronic device cable, and method

Abstract

The present disclosure relates to braided electronic device cables, braiding machines and methods for braiding electronic device cables. The present application relates to cable assemblies having an outer (exterior) layer formed by braiding materials together. To achieve a desired pattern, the machine tool that forms the outer layer is modified in several ways. For a machine tool that includes two tracks (e.g., an inner track and an outer track) with multiple carriers of material to be braided, each carrier position can include multiple spools, with each spool carrying a spooling / turn of material. During a braiding operation performed by the machine tool, each track rotates in opposite directions. In addition, some spools include arms that direct the material in a particular way. For example, during rotation of the tracks, the arms provide a wobbling motion that moves the material carried by the arms in a periodic (e.g., sinusoidal) motion. Additional tracks can be used to direct the arms.

Description

Technical Field

[0001] The embodiments described herein generally relate to cable assemblies or rope assemblies for portable electronic devices. More specifically, the embodiments herein relate to yarn braiding techniques for creating the outer surface of cable assemblies. Background Technology

[0002] Cables may include a sheath or sleeve for bundling multiple wires together. Typically, the sheath is covered by an outer layer of material forming the exterior of the cable, such as a polymer (e.g., polyvinyl chloride). The sheath may include multiple metallic wires, such as copper wires, forming a protective cover for the wires carrying electrical signals. Additionally, the sheath may protect the user relative to the energized wires.

[0003] Machine automation is commonly used in sheath production. Unlike the external, aesthetically pleasing exterior of consumer products, several factors influence the use of sheath pattern designs as internal features. For example, woven sheaths produced by typical machine knitting tools often exhibit inconsistencies in thread angle, coverage percentage, and density. While this may be permissible when the sheath is covered, it becomes a readily detectable problem when the sheath represents the exterior. When machine modifications are employed to improve manufacturing consistency, throughput (i.e., production rate) often decreases, making it less feasible to produce sheath pattern designs as external features. Consequently, manufacturers are typically constrained by design choices. Summary of the Invention

[0004] In one aspect of this disclosure, a machine tool for manufacturing cable assemblies is described. The machine tool may include a first set of spools configured for rotational movement in a first direction. The first set of spools may include a first spool and a second spool. The machine tool may also include a second set of spools configured for rotational movement in a second direction different from the first direction. The second set of spools may include a third spool carrying material. The machine tool may include a track defining a periodic pattern. The machine tool may include an arm coupled to the track. The arm may be configured to actuate the material above the first spool and below the second spool based on the periodic pattern.

[0005] In another aspect of this disclosure, a method for manufacturing a cable assembly is described. The method may include driving a first track in a first direction by a machine tool. The first track may carry a first set of strands. The method may further include driving a second track in a second direction opposite to the first direction by the machine tool. The second track may carry a second set of strands. The method may further include actuating the second set of strands by the machine tool via a plurality of arms as the plurality of arms move along the second direction. In some embodiments, the plurality of arms guide the second set of strands according to a periodic pattern.

[0006] In another aspect of this disclosure, a cable assembly is described. The cable assembly may include a first connector. The cable assembly may also include a second connector. The cable assembly may further include a cord extending between the first connector and the second connector. The cord may include an outer layer. The outer layer may include a first set of strands. The outer layer may further include a second set of strands adjacent to the first set of strands. The outer layer may further include a third set of strands interwoven with the first set of strands and the second set of strands.

[0025] This section describes representative applications of the methods and apparatus according to this application. These examples are provided only to add context and aid in understanding the described embodiments. Therefore, it will be apparent to those skilled in the art that the described embodiments can be practiced without some or all of these specific details. In other instances, well-known processing steps have not been described in detail to avoid unnecessarily obscuring the embodiments. Other applications are possible, such that the following examples should not be considered limiting.

[0026] In the following detailed description, reference is made to the accompanying drawings, which form part of this specification, and specific embodiments according to the described embodiments are illustrated by way of example. While these embodiments are described in sufficient detail to enable those skilled in the art to practice them, it should be understood that these examples are not limiting; other embodiments can be used, and modifications can be made without departing from the spirit and scope of the described embodiments.

[0027] This application relates to cable assemblies having a braided outer layer or braided exterior, and machine tools for forming the braided outer layer. The cable assemblies described herein are used to facilitate power transfer from a power adapter for connection to, for example, a 110-120 volt (“V”) source to electronic devices (e.g., smartphones, desktop computing devices, smartwatches, laptop computing devices, tablet computing devices, etc.). Alternatively or in combination, the cable assemblies described herein are used to facilitate power transfer and / or communication (e.g., data) from one electronic device to another.

[0028] In an exemplary embodiment, the cable assembly includes an outer layer made of multiple strands of yarn woven together. Specifically, the outer layer may include a braided pattern according to the following formula.

[0029] a×bc

[0030] Where 'a' is the number of groups of ply yarns (e.g., yarns) passing above and below the group number of ply yarns (b), and 'c' is the number of ply yarns in each group. For example, a 1×1-2 weave pattern includes one group of ply yarns passing above and below the group number of ply yarns, where each group has two ply yarns. In this way, machine tools can form a 1×1-2 weave pattern by using 2 (or c) spools at each carrier location. In this detailed description, 'a' and 'b' can vary from 1 to 5, while 'c' can vary from 1 to 10.

[0031] To generate the outer layer of a cable assembly, machine tools may include rotary braiding machines with several modifications. For example, a two-track machine tool, each having multiple carriers (or multiple spools at a single carrier position) for holding spools, may include a track with several arms for guiding or directing material strands as they turn off their respective spools. The arms may be passively driven, i.e., connected to an additional track that moves the arms along a path defined by that additional track. In some exemplary embodiments, the additional track includes a periodic pattern, such as a sine pattern. Based on the track's position on the machine tool, actuation of the material strands (guided by their respective arms) moves the strands toward and away from the spool on another track, thereby providing a braiding / interlacing operation. In some exemplary embodiments, the two-track machine tool includes an inner track and an outer track, each track having several carriers. Each spool on the outer track includes an arm that guides the material strands away from the spool in a direction toward the spool on the inner track (and in some cases, radially inside it) and also away from the spool on the inner track (and radially outside it), thereby defining a periodic pattern. As an alternative to a track with a periodic pattern design, a motor can be fitted to each arm to drive the arm in a desired manner, which may include periodic motion.

[0032] Conventional rotary braiding machines for cable assemblies form sheaths to hold the wires of the cable assembly together. These braided sheaths are then covered by an outer layer, making the sheaths invisible. However, the braiding operation described herein is used to generate an outer layer, or outer layer, and therefore factors related to the appearance of the outer layer, and thus to the appearance of the cable assembly, such as strand angles, coverage percentage, and strand density, are relatively more important. In this regard, additional modifications to the machine tool can be used. For example, the machine tool described herein may include a fixing device centrally mounted to the machine tool. The fixing device serves as an initial receiving surface for the outer layer undergoing the braiding operation. The fixing device also includes a hollow cylindrical body defining a through-hole through which internal features of the cable assembly (e.g., the cable core including the wires and other internal features) pass. Additionally, the fixing device may include a tapered body, with a diameter at one end larger than the diameter at the other end. This fixing device is designed to reduce tension on the braided outer layer during manufacturing operations and to keep the braided outer layer temporarily separated from the cable core. Therefore, the braided outer layer experiences less stress and tension, resulting in a more consistent and aesthetically pleasing finish.

[0033] The following is for reference Figures 1 to 15 These embodiments and other embodiments will be discussed herein. However, those skilled in the art will readily understand that the detailed descriptions given herein with respect to the accompanying drawings are for illustrative purposes only and should not be construed as limiting.

[0034] Figure 1An isometric view of an embodiment of cable assembly 100 is shown. Cable assembly 100 (representing other cable assemblies shown and described herein) is designed for use with a variety of electronic devices, including but not limited to smartphones, laptops, desktops, tablets, wireless headsets, and digital styluses. As shown, cable assembly 100 includes connectors 102a and 102b. Each of connectors 102a and 102b may include an electrical connector designed according to industry standards, including but not limited to Universal Serial Bus (“USB”), USB-C, Lightning, Thunderbolt, or MicroUSB.

[0035] Furthermore, the cable assembly 100 includes a cable 104 or rope extending between and connected to connectors 102a and 102b. The cable 104 is designed to cover and carry one or more wires for power transmission and / or data transmission from connector 102a to connector 102b or vice versa, and thus, the cable assembly 100 can provide power transmission and / or data transmission to various electronic devices. As shown in the enlarged view, the cable 104 includes an outer layer 106, also referred to as the outer layer or outer layer. In some embodiments, the outer layer 106 includes several strands of material braided or interwoven together. As a non-limiting example, the material strands may include yarn. The outer layer 106, including its manufacture and design, will be shown and described below.

[0036] Figure 2 A cross-sectional view of the cable assembly 100 taken across line 2-2 is shown, illustrating the various internal features of the cable 104. As shown, the outer layer 106 provides the external structure and surface of the cable 104. Additionally, the cable 104 includes wires 108a, 108b, and 108c, each covered / wrapped by insulators 110a, 110b, and 110c, respectively. Wires 108a, 108b, and 108c provide conductive paths and therefore include conductive metals such as copper. Wires 108a, 108b, and 108c are electrically connected to connectors 102a and 102b (e.g., ...). Figure 1 (As shown). Insulators 110a, 110b, and 110c comprise electrically insulating materials, such as polymers. Additionally, to improve power transmission and / or data transmission, cable 104 may include uninsulated wires 112a, 112b, and 112c, each of which is electrically connected to connectors 102a and 102b. Furthermore, cable 104 may also include a filler material 114, such as nylon. The filler material 114 may generally comprise any material that has flexible properties while providing a certain degree of rigidity.

[0037] Additionally, cable 104 may include a sheath 115 for providing some compressive force to components of cable 104. Furthermore, cable 104 may include a metallic separator 117 designed to provide a certain grounding for static charges. Features and components within the sheath 115 may define the cable core of cable 104 for cable assembly 100.

[0038] Figure 3 A plan view of the outer layer 106 of the cable assembly 100 is shown. As shown, the outer layer 106 is separate from the cable assembly 100 and lies flat. The outer layer 106 includes a plurality of material strands (shown but not labeled) braided or interwoven together. Thus, some material strands pass above some material strands and below others.

[0039] Figure 4 A partial cross-sectional view of outer layer 106 is shown, illustrating the pattern of the material strands in outer layer 106. As shown, outer layer 106 includes strands 116a and 116b extending in the same direction. In other words, strands 116a and 116b are parallel to each other. Outer layer 106 includes additional strands extending in a different direction from strands 116a and 116b and therefore intersecting / crossing with strands 116a and 116b. For example, outer layer 106 includes strands 118a and 118b extending in the same direction, and strands 120a and 120b extending in the same direction. As shown, strands 116a and 116b pass over strands 118a and 118b and subsequently pass under strands 120a and 120b.

[0040] The stock lines can be divided into groups. For example, stock lines 116a and 116b define group 122a of stock lines, stock lines 118a and 118b define group 122b of stock lines, and stock lines 120a and 120b define group 122c of stock lines. In this way, it can be said that group 122a passes above group 122b and then below group 122c. In some implementations (such as...) Figure 4 As shown), groups 122b and 122c are adjacent to each other. For strands, the term "adjacent" or the phrase "adjacent groups" as used in this detailed description and claims can refer to two groups (including their respective strands) that extend in the same direction (i.e., parallel) and are not separated by another group. Furthermore, as shown, group 122a interweaves with adjacent groups, with groups 122b and 122c being representative examples.

[0041] Figure 5A plan view of a machine tool 230 designed for manufacturing an outer layer for a cable assembly, according to some described embodiments, is shown. The machine tool 230 includes multiple carrier positions designed to hold one or more spools or reels loaded with material for generating the outer layer. For example, the machine tool 230 includes spools 232a and 234 at respective carrier positions, each spool representing an additional spool of the machine tool 230. As shown, spools 232a and 234 each provide strands 236a and 236b, respectively. Strands 236a and 236b may comprise one or more material fibers. In this respect, by way of non-limiting example, strands 236a and 236b may comprise yarn. However, various fabrics and synthetic materials are also possible for strands 236a and 236b. Although each of spools 232a and 234 comprises material strands, spools 232a and 234 are located on different tracks. For example, spool 232a and other similar spools are mounted on track 238a, while spool 234 and other similar spools are mounted on track 238b. Tracks 238a and 238b may be referred to as the inner track and outer track, respectively, based on their respective positions.

[0042] To perform the weaving operation, machine tool 230 drives tracks 238a and 238b in opposite directions. For example, track 238a is designed to be driven in the direction indicated by arrow 240a, while track 238b is designed to be driven in the direction indicated by arrow 240b. Although not shown, tracks 238a and 238b can be driven by one or more motors of machine tool 230. The directions indicated by arrows 240a and 240b can represent counterclockwise and counter-clockwise directions, respectively. Typically, machine tool 230 operates by driving each of tracks 238a and 238b in their respective opposite directions as shown. The corresponding strands on the spools on track 238a are woven with the strands on the spools on track 238b.

[0043] Additionally, to further generate the desired finish, the outer layer of the cable assembly, machine tool 230 may include additional modifications to at least some of the spools. For example, machine tool 230 includes a track 238c and an arm 242 connected to the track 238c. The track 238c may define a periodic pattern that repeats at defined intervals. For example, in some embodiments, the track 238c defines a sinusoidal pattern that repeats in each period. Thus, when the track 238b moves in the direction of arrow 240b (i.e., circular motion), the arm 242 connected to the track 238c not only moves with the spool 234 in the direction of arrow 240b, but also oscillates or oscillates in a manner defined by the shape and curvature of the track 238c, i.e., a periodic pattern. Furthermore, the strands 236b (located on the spool 234) are guided / directed by the arm 242, and therefore, the strands 236b also move according to the periodic pattern of the track 238c. As shown in the figure, the additional arm (unmarked) is connected to the spool on the track 238b and is able to guide the corresponding strands on the spool loaded on the track 238b.

[0044] In addition to the periodic pattern, the layout and dimensions of track 238c allow arms 242 and strands 236b to pass between adjacent spools. For example, based on track 238c, arms 242 and strands 236b can pass between spools 232a and 232b, wherein spool 232b is adjacent to spool 232a and on track 238a. For spools, the term "adjacent" or the phrase "adjacent spools" as used in this detailed description and claims can refer to two spools on the same track and not separated by another spool on the same track.

[0045] Figure 6 It shows Figure 5 An enlarged view of the machine tool 230 is shown, illustrating exemplary movements of the spool 234 at various positions during operation. For illustrative and simplicity, some features of the machine tool 230 have been removed. Dashed lines indicate several different positions of the spool 234, arm 242, and strand 236b during operation of the machine tool 230. For example, as the spool 234 travels along track 238b, the arm 242 moves along a periodic pattern defined by track 238c, and thus, although both the spool 234 and the arm 242 move in the direction of arrow 240b, the arm 242 still moves relative to the spool 234. Additionally, the strand 236b is guided by the arm 242 and therefore moves along a periodic pattern defined by track 238c.

[0046] Figure 7An enlarged view of an alternative embodiment of machine tool 330 according to some described embodiments is shown, illustrating multiple spools at a single carrier position. Machine tool 330 may include any features shown and described herein as machine tools. However, machine tool 330 may include two spools at a single carrier position. For example, machine tool 330 includes spools 332a and 332b located at a carrier position on track 338a and carrying strands 336a and 336b respectively. Additionally, machine tool 330 includes spools 334a and 334b ​​located at a carrier position on track 338b and carrying strands 336c and 336d respectively. Furthermore, spools 334a and 334b ​​each include arms 342a and 342b, wherein arms 342a and 342b are used to guide strands 336c and 336d respectively. Spools 334a and 334b ​​are connected to track 338b by support member 344a, while arms 342a and 342b are connected to track 338c by support member 344b. Support members 344a and 344b are respectively positioned in grooves in tracks 338b and 338c.

[0047] Tracks 338a, 338b, and 338c may respectively include similar features and designs for tracks 238a, 238b, and 238c. Figure 5 (As shown in the diagram). Therefore, tracks 338a and 338b can be driven in directions 340a and 340b (i.e., opposite directions), respectively, and track 338c can define a periodic pattern, including a sinusoidal pattern. In this way, during operation, arms 342a and 342b can move relative to spools 334a and 334b, respectively, and simultaneously move / oscillate / oscillate, thereby guiding strands 336c and 336d along the periodic pattern, respectively. The movement of arms 342a and 342b can cause strands 336c and 336d to move radially inside and outside axes 332a and 332b located on track 338a, respectively. In this way, track 338a can include an opening 346 that allows strands 336c and 336d to pass through track 338a.

[0048] Based on the dual-spool configuration, machine tool 330 can form an outer layer with a 1×1-2 braided pattern (previously described). In other words, two strands of a single group (e.g., strands 336a and 336b) can pass above two strands of another single group (e.g., strands 336c and 336d) and below two strands of another group (i.e., another dual-spool at the carrier position on track 338b). In this respect, although not shown, arms 342a and 342b can swing strands 336c and 336d above, respectively, another dual-spool configuration located on track 338a adjacent to spools 332a and 332b. At each carrier position of machine tool 330 ( Figure 7In the case of multiple groups of double spools (not shown), the outer layer can be formed according to a 1×1-2 pattern. Furthermore, although not shown, the "2" in 1×1-2 can be changed (increased or decreased) based on the number of spools at a single carrier position.

[0049] Figure 8 An enlarged view of an alternative embodiment of machine tool 430 according to some described embodiments is shown, illustrating different movements of the arms. Machine tool 430 may include any features shown and described herein as machine tools. For example, machine tool 430 includes spools 432a and 432b on track 438a that respectively carry strands 436a and 436b. Additionally, machine tool 430 includes spools 434a and 434b located at carrier positions on track 438b and respectively carrying strands 436c and 336d. Furthermore, spools 334a and 334b ​​respectively include arms 442a and 442b.

[0050] Tracks 438a and 438b may respectively include similar features and designs for tracks 238a and 238b. Figure 5 (As shown in the diagram). Therefore, tracks 438a and 438b can be driven in opposite directions. To drive arms 442a and 442b, machine tool 430 may also include a motor (e.g., a servo motor) that drives arms 442a and 442b to oscillate / oscillate in the direction indicated by the double arrows 448. In this way, during operation, track 438b moves in the direction of arrow 440, causing spools 434a and 434b and arms 442a and 442b to move relative to track 438b, while arms 442a and 442b additionally oscillate / oscillate, thereby driving strands 436c and 436d respectively along a periodic pattern indicated by arrow 450. The movement of arms 442a and 442b can cause strands 436c and 436d to move above and below spool 432b, respectively. Additionally, track 438a may include openings 446a and 446b, each opening allowing strands 436c and 436d to pass through track 438a.

[0051] Figure 9An isometric view of a fixture 460 designed for use with a machine tool, according to some described embodiments, is shown. The fixture 460 can be mounted to any machine tool described herein. As shown, the fixture 460 defines a cylindrical (or generally cylindrical) body having one end with a diameter 462a, a tapered region 464, and another end with a diameter 462b. The diameter 462a is larger than the diameter 462b due to the tapered region 464. The fixture 460 also includes a through-hole 466 that opens to an opening 468a at one end (i.e., the receiving end) and to an opening 468b at the other end (i.e., the transmitting end). For securing the fixture 460 to the machine tool, a base 470 can be mounted to the machine tool. In this respect, the fixture 460 includes a flange 469 designed to fit into a recess 472 in the base 470.

[0052] The fixing device 460 is designed to reduce tension on the outer layer during the assembly operation of the outer layer. Figure 9 (Not shown in the text). For example, the fixing device 460 may be centrally mounted on the machine tool described herein, and during operation, the strands used to form the outer layer pass above the outer surface of the fixing device 460, while the cable core initially passes through the through hole 474 of the base 470, and then through the through hole 466 by initially passing through the opening 468a and then through the opening 468b.

[0053] Figure 10 A partial cross-sectional view of a fastening device 560 for manufacturing a cable assembly according to some described embodiments is shown. The fastening device 560 may include any features shown and described for the fastening device 460. Figure 9 (As shown in the diagram). During operation, the cable core 574 of the cable assembly and the strands 576 from the various spools of the machine tool are guided to the fixing device 560. The strands 576 are braided to form an outer layer 506 that passes over the outer surface of the fixing device 560, while the cable core 574 passes through a through-hole in the fixing device 560 (not labeled, but similar to...). Figure 9 (Through hole 466 in the middle). Arrow 580 is used to indicate the direction of travel of cable core 574 and outer layer 506 during operation.

[0054] As shown in the figure, the fixing device 560 provides physical separation between the outer layer 506 and the cable core 574 during the formation of the outer layer 506. Therefore, the cable core 574 applies minimal stress (if any) to the outer layer 506. This decoupling between the outer layer 506 and the cable core 574 provides a reduced stress environment for the outer layer 506 and improves the braiding consistency and aesthetics of the outer layer 506. Furthermore, the tapered region (unmarked, but similar) Figure 9 The tapered region 464 in the middle and the reduced end of the fixing device 560 (similar to) Figure 9 The end shown (with a diameter of 462b) provides a smooth transition for the outer layer 506 to slide off the retainer 560 and onto the cable core 574. In this way, the retainer 560 allows the outer layer 506 to transition onto the cable core 574 without the cable core 574 stretching the outer layer 506 in a way that undesirably alters its appearance.

[0055] Figures 11A to 11C A cross-sectional view of an alternative embodiment of the fixing device is shown. Figures 11A to 11C Any of the fixing devices shown and described may replace fixing device 560. Figure 9 and Figure 10 (As shown in the image). Additionally, the fixing devices 460 and 560 can be modified (respectively in...). Figure 9 and Figure 10 (as shown in the image) to include Figures 11A to 11C At least some of the features of the fixing device shown and described.

[0059] Figure 12 A cross-sectional view of strand 932 for forming the outer layer of a cable assembly, according to some described embodiments, is shown. As shown, strand 932 has a diameter 978. The diameter 978 is approximately in the range of 0.1 mm to 1 mm. Additionally, strand 932 is illustrated as having a generally circular cross-section. However, other cross-sectional shapes (including rectangular shapes due to the strand being stretched and under tension) are also possible.

[0060] Figure 13 A plan view of the outer layer 1006 of a cable assembly according to some described embodiments is shown, illustrating the additional relationship of the strands of the outer layer 1006. As shown, the outer layer 1006 includes strands 1032 positioned at an angle α relative to an imaginary vertical line 1082. The angle α may be in the range of approximately 15 degrees to 60 degrees. Moreover, the strands of the outer layer 1006 (including strands 1032) provide basic coverage or a sheath for the cable assembly. However, some gaps or openings may exist between adjacent strands. For example, a gap 1084 is shown between (and defined by) several surrounding strands. Gap 1084 represents an area of ​​the cable assembly not covered by the outer layer 1006, i.e., where no strands of the outer layer 1006 are present. Based on the manufacturing process, the outer layer 1006 is designed to provide coverage in the range of approximately 75% to 95%. Additionally, region 1086 of the outer layer 1006 is shown. Within region 1086 (representing the remaining area of ​​outer layer 1006), the weft per inch (“ppi”) is approximately in the range of 10 to 60 ppi.

[0061] Figure 14 A flowchart 1100 illustrates a method for manufacturing a cable assembly according to some described embodiments. The methods shown and described in flowchart 1100 can be implemented by the machine tools described herein. In particular, flowchart 1100 shows and describes how the machine tools can braid / interlace the outer layer of the cable assembly.

[0062] In step 1102, a first track is driven along a first direction. The first track may carry a first set of strands. For example, the first track may include several carrier positions designed to hold one or more spools. Each spool may include material strands for forming the outer layer of a cable assembly. As a non-limiting example, the material strands may include yarn.

[0063] In step 1104, the second track is driven in a second direction opposite to the first direction. The first and second directions may include opposite directions of rotation. Similar to the first track, the second track may also carry a second set of strands made of a material similar to that of the first set of strands. While the material may be similar, other appearances (e.g., color) may differ. Alternatively, the material (including composition) may differ on different tracks and / or on different spools.

[0064] In step 1106, as the arms move in the second direction, a plurality of arms actuate a second set of strands. For example, in some embodiments, the arms (one arm for each spool on the second track) may guide the second set of strands according to a periodic pattern, which may include a (repeated) sine wave pattern. The machine tool may include a third track defining the periodic pattern. In this way, as the second set of strands and the arms move in the second direction, the arms also guide the material (i.e., the strands) along the periodic pattern. When the first track is inside the second track (or alternatively, the second track is outside the first track), the arms may guide the strands toward the spools on the first track (including their inside) and away from the spools on the first track (including their outside). As an alternative to the third track, each arm may be driven by a motor (e.g., a servo motor) according to the periodic pattern.
