     BACKGROUND 
     This relates generally to electronic devices, and, more particularly, to electronic devices having electrical components mounted to fabric. 
     Fabric can be provided with metal wires and other conductive fibers. These fibers can be used to carry signals for electrical components. An electronic device can be formed from a fabric that contains electrical components. 
     Challenges may arise when mounting electrical components to fabric. If care is not taken, stresses on the fabric will tend to dislodge the electrical components. Short circuits can develop if signal paths are not properly isolated. Overly prominent mounting arrangements may be unsightly. 
     It would be desirable to be able to address these concerns by providing improved techniques for mounting electrical components to fabric for an electronic device. 
     SUMMARY 
     An electronic device may include fabric formed from intertwined fibers. Electrical components may be mounted to the fibers. The fibers may include conductive fibers that convey signals between the electrical components and control circuitry in the electronic device. 
     Component contacts may be formed on a package for a component. Each component may be coupled to fibers in the fabric using electrical connections. The fabric may be a woven fabric having warp and weft fibers or other suitable fabric. 
     A first electrical connection may be formed between a first contact and a first fiber. A second electrical connection may be formed between a second contact and a second fiber. Optional additional connections may also be made with one or more other fibers. The connections may be formed using different types of connection materials and/or different types of connection structures. 
     Fabric configurations may also be used in which fibers in the fabric overlap the component to help hold the component in place.

     The fabric to which the electrical components have been mounted may form all or part of an electronic device, may form all or part of a housing wall for an electronic device, may form internal structures in an electronic device, or may form other fabric-based structures. The fabric-based device may be soft (e.g., the device may have a fabric surface that yields to a light touch), may have a rigid feel (e.g., the surface of the device may be formed from a stiff fabric), may be coarse, may be smooth, may have ribs or other patterned textures, and/or may be formed as part of a device that has portions formed from non-fabric structures of plastic, metal, glass, crystalline materials, ceramics, or other materials. 
     In the illustrative configuration of  FIG. 1 , device  10  has portions that may be formed from fabric such as upper face  12 - 1  and sidewalls  12 - 2 .

The illustrative layout of components  20  of  FIG. 1  and the illustrative shape of device  10  of  FIG. 1  are merely provided as examples. 
     A schematic diagram of an illustrative electronic device that may include fabric to which one or more components  20  have been mounted is shown in  FIG. 2 . As shown in  FIG. 2 , device  10  may include input-output devices  26 . Devices  26  may include components  20 .

Devices  26  may, for example, include solenoids, vibrators, or other components that provide physical feedback (e.g., vibrations) to a user in conjunction with a button press, touch input, or other user activity. Changes in fabric attributes such as fabric temperature, texture, size, and shape may also be produced using devices  26  to convey output to a user. 
     Illustrative equipment of the type that may be used in mounting one or more electrical components to fabric for device  10  is shown in  FIG. 3 . As shown in  FIG. 3 , the equipment of  FIG. 3  may be provided with fibers from fiber source  28 . The fibers provided by fiber source  28  may be single-strand filaments or may be threads, yarns, or other fibers that have been formed by intertwining single-strand filaments. Fibers may be formed from polymer, metal, glass, graphite, ceramic, natural materials such as cotton or bamboo, or other organic and/or inorganic materials and combinations of these materials. Conductive coatings such as metal coatings may be formed on non-conductive fiber cores. Fibers may also be formed from single filament metal wire or stranded wire. Fibers may be insulating or conductive. Fibers may be conductive along their entire length or may have conductive segments (e.g., metal portions that are exposed by locally removing polymer insulation from an insulated conductive fiber). Threads and other multi-strand fibers that have been formed from intertwined filaments may contain mixtures of conductive fibers and insulating fibers (e.g., metal fibers or metal coated fibers with or without exterior insulating layers may be used in combination with solid plastic fibers or natural fibers that are insulating). 
     The fibers from fiber source  28  may be intertwined using intertwining equipment  30 . Equipment  30  may include weaving tools, knitting tools, tools for forming braided fabric, or other equipment for intertwining the fibers from source  28 . Equipment  30  may be automated. For example, equipment  30  may include computer-controlled actuators that manipulate and intertwine fibers from source  28 . 
     Components  20  may be attached to fibers in the fabric formed with equipment  30 . For example, computer-controlled equipment such as pick-and-place tool  32  may be used to attach components  20  to the fibers. Components  20  may have conductive contacts (e.g., contacts formed from metal or other conductive material). Equipment  32  may attach each conductive contact in a component  20  to a respective conductive fiber using conductive connections such as solder joints, conductive adhesive connections (e.g., conductive epoxy connections), welds, crimped connections, spring contacts, connections formed using clamps, fasteners, or other structures to press metal contacts against conductive fibers, etc. Arrangements in which equipment  32  uses solder to attach components  20  to fibers from source  28  that are being formed into fabric by tool  30  are sometimes described herein as an example. This is, however, merely illustrative. In general, any suitable conductive attachment mechanism may be used to electrically couple one or more terminals in each component  20  to a respective conductive fiber in a fabric for device  10 . Adhesive and other attachment mechanisms may also be used to attach insulating fibers to component  20 . 
     After using intertwining tool  30  and pick-and-place tool  32  to form fabric and other structures  34  with embedded components  20 , additional processing steps may be performed using equipment  36 . Equipment  36  may include equipment for assembling control circuitry  24 , components  26 , and other structures for device  10  with the fabric produced by equipment  32  and  30 , thereby forming all or part of finished device  10 . Equipment  36  may include injection molding tools, tools for applying coatings, cutting and machining equipment, assembly equipment for attaching structures together using fasteners, adhesive, and other attachment mechanisms, equipment for interconnecting connectors on printed circuits and other signal path substrates, etc. 
     If desired, intertwining tool  30  may be a weaving machine. Illustrative weaving equipment is shown in  FIG. 4 . As shown in  FIG. 4 , weaving equipment  30  includes a source of warp fibers such as source  70 . Source  70  may include a drum or other structure such as drum  42  that rotates about rotational axis  44  in direction  46 . Warp fibers  40 - 1  and warp fibers  40 - 2  may be dispensed as drum  42  rotates. 
     Warp fibers  40 - 1  may be positioned using computer-controlled positioner  50 - 1  and needles  48 - 1  or other fiber guiding structures. Warp fibers  40 - 2  may be positioned using computer-controlled positioner  50 - 2  and needles  48 - 2  or other fiber guiding structures. Positioners  50 - 1  and  50 - 2  may travel along vertical axis  52  (e.g. to move warp fibers  40 - 1  down while moving warp fibers  40 - 2  up to swap the positions of fibers  40 - 1  and  40 - 2 ). 
     Shuttle  58  or other weft fiber positioning equipment may be used to insert weft fiber  60  between warp fibers  40 - 1  and  40 - 2  (e.g., by moving weft fiber  60  into the page and out of the page in the orientation of  FIG. 4 . After each pass of shuttle  58 , reed  55  may be moved in direction  56  (and then retracted) to push the weft fiber that has just been inserted between warp fibers  40 - 1  and  40 - 2  against previously woven fabric  62 , thereby ensuring that a satisfactorily tight weave is produced. Fabric  62  that has been woven in this way may be gathered on drum  66  as drum  66  rotates in direction  64  about rotational axis  68 . 
     The equipment of  FIG. 4  may be controlled using computing equipment. For example, computing equipment may control the positions of needles  48 - 1  and  48 - 2  using positioners  50 - 1  and  50 - 2  and computer-controlled positioners may be used in controlling the movement of reed  55 , shuttle  58 , and drums  42  and  66 . The computing equipment may also control equipment for installing components  20  in fabric  62 . With one suitable arrangement, computer-controlled equipment such as pick-and-place machine  32  of  FIG. 3  may be used to solder components  20  to fibers in fabric  62 . 
     An illustrative pick-and-place machine is shown in  FIG. 5 . As shown in  FIG. 5 , pick-and-place machine  32  may include computer-controlled actuators such as computer-controlled positioner  84 . Positioner  84  may be used to position pick-and-place head  82 . Head (nozzle)  82  may include a vacuum suction structure or other gripping device for gripping components such as component  20 . Components  20  may be fed into machine  32  on a reel of tape or other suitable component dispensing structure. 
     When it is desired to mount component  20  to a fiber in fabric  62  such as fiber  74  (e.g., a warp fiber or a weft fiber in a woven fabric), head  82  may be positioned so that conductive material  76  is interposed between component  20  and fiber  74 . Fiber  74  may be a bare metal wire, a metal-coated insulating fiber, a metal wire or metal-coated insulating fiber with a locally stripped insulating coating, a multi-strand fiber that contains at least one metal fiber or metal-coated fiber, or other conductive fiber. Component  20  may have metal contacts such as contact  78 . Conductive material  76  may be solder, conductive adhesive, or other conductive material for connecting contact  78  to conductive fiber  74  and thereby electrically and mechanically joining component  20  to fiber  74 . Conductive material  76  such as solder may be dispensed in the form of solder paste that is heated (reflowed) using a heating element in head  82  and/or using an external source of heat. Solder paste  76  may be carried with components  20  on the tape reel in machine  32 , may be applied as part of the process of attaching component  20  to fiber  74 , and/or may be applied to fiber  74  before mounting component  20 . If desired, different types of solder may be used in forming joints for different contacts  78  on a single component. For example, solders that melt (flow) at different temperatures may be used to form different connections. 
       FIG. 6  is a top view of an illustrative fabric having fibers  74  to which components  20  may be mounted using pick-and-place tool  32 . In the example of  FIG. 6 , fabric  62  is a woven fabric that has a plain weave and includes warp fibers  40 - 1  and  40 - 2  and weft fibers  60 . In general, fabric  62  may include any intertwined fibers  74  (woven, knitted, braided, etc.). The plain weave fabric of  FIG. 6  is merely illustrative. Fabric  62  may contain conductive fibers and/or may contain a mixture of conductive and insulating fibers. The contacts  78  of components  20  may be electrically coupled to the conductive fibers in fabric  62 . 
     Illustrative soldering locations  86  of the type where contacts  78  of components  20  may be soldered to fibers  74  are shown in  FIG. 6 . Components  20  may have two or more terminals (contacts  78 ), three or more terminals, four or more terminals, or other suitable number of terminals. In configurations in which components  20  each have a pair of terminals, one terminal may be coupled to a conductive warp fiber and another terminal may be coupled to a conductive weft fiber, first and second terminals may be coupled to a common conductive warp fiber or to two different conductive warp fibers, or first and second terminals may be coupled to a common conductive weft fiber or to two different conductive weft fibers. In configurations in which components  20  each have three or more terminals, additional combinations of warp and weft fibers may be coupled to the terminals. A pair of soldering locations  86  for a component may be located on horizontally adjacent fibers  74 , may be located on vertically adjacent fibers  74 , may be located along a diagonal line that runs across fabric  62 , may be formed on fibers  74  that are separated by intervening insulating fibers  74  or other fibers  74  to which connections are not made, or may be located on any other suitable first and second respective positions on fibers  74 . 
       FIG. 7  is a perspective view of an illustrative electrical component of the type that may be attached to fibers  74  in fabric  62 . In the example of  FIG. 7 , component  20  has a package such as package  90 . Package  90  may be formed from plastic, ceramic, or other materials. Component  20  may include one or more electrical devices such as device  92 . Devices such as device  92  may include one or more semiconductor dies or other circuits. For example, device  92  may be a silicon integrated circuit, a silicon-based microelectromechanical systems device such as a sensor, a capacitor, inductor, or resistor, a compound semiconductor die that forms a light-emitting diode or light detector, a semiconductor substrate that is configured to form a membrane for a microphone or a diving board structure for a sensor or other component, or semiconductor switch or driver circuit, or other suitable electrical device. Devices  92  may be shielded using conductive shield structures and may be encased within an enclosure such as package  90 . If desired, a printed circuit board or other substrate with traces may be enclosed within package  90  (e.g., devices  92  may be mounted to a printed circuit before encasing the printed circuit and devices  92  within a plastic package body using injection molding techniques). Signal lines in component  20  may be formed from metal traces  94  on a printed circuit or other structures in component  20 . Metal traces  94  may be used to couple the terminals of electrical device  92  or other circuitry to component contacts in component  20 . 
     If desired, package body  90  may be provided with fiber guiding structures that receive and hold fibers  74 . The guiding structures may include posts, walls, or other protrusions, flat sided and curved recesses forming grooves, combinations of protrusions and recesses, or other structures that receive fibers  74  and help prevent fibers  74  from slipping off of body  90 . In the illustrative example of  FIG. 7 , package body  90  has grooves such as grooves  96  and  96 ′. The upper surface of body  90  has parallel grooves and the lower surface of body  90  has a perpendicular groove. 
     Contacts for component  20  may be formed in these grooves or elsewhere on the exterior of body  90 . For example, a first contact such as contact  78 A may be formed on a first of grooves  96  and a second contact such as contact  78 B may be formed on a second of grooves  96 . Contacts  78 A and  78 B may be formed from a solder-compatible metal. Traces  94  may couple contacts  78 A and  78 B to respective electrical terminals of device  92  and/or other circuitry in package body  90 . If desired, component  20  may have additional contacts. For example, an additional contact may be formed in groove  96 ′ and may be soldered to another conductive fiber. Insulating fibers and other fibers may also be mounted in groove  96 ′ using adhesive (e.g., to provide structural support without providing any electrical signal path). The arrangement of  FIG. 7  is merely illustrative. 
     In the example of  FIG. 7 , component  20  has an elongated shape that extends along longitudinal axis  100 . Contact  78 B extends along the groove in package  90  that runs parallel to axis  100 . Contact  78 A extends along the groove in package  90  that runs along perpendicular axis  102 . When installed within fabric  62 , axis  100  may be aligned with weft fibers  60  and axis  102  may be aligned with warp fibers  40 - 1  and  40 - 2  (or vice versa). As shown in  FIG. 8 , for example, contact  78 B may be a weft fiber contact that is soldered to weft fiber  60  with solder  76 B and contact  78 A may be a warp fiber contact that is soldered to warp fiber  40 - 1  with solder  76 A. Warp fiber  40 - 2  may be an insulating fiber that is attached to package  90  with adhesive but that is not electrically coupled to a contact in component  20  or warp fiber  40 - 2  may be a conductive fiber that is soldered to a contact in groove  58 ′. 
     If desired, solder  76 B and solder  76 A may be formed from different types of solder and may exhibit different melting temperatures. This may facilitate attachment of component  20  to fabric  62  using pick-and-place equipment  32  as fabric  62  is woven using equipment  30 . 
     Illustrative steps involved in mounting component  20  to fabric  62  during weaving operations are shown in  FIGS. 9, 10, 11, 12, 13, and 14 . 
       FIG. 9  is a diagram of a portion of weaving machine being used to produce fabric  62 . As shown in  FIG. 9 , woven fabric  62  includes weft fibers  60 ′ intertwined with warp fibers  40 - 1  and  40 - 2 . Using equipment of the type shown in  FIG. 4 , a weft fiber such as weft fiber  60  may be inserted between warp fibers  40 - 1  and warp fibers  40 - 2 . 
     Following insertion of weft fiber  60 , a pick-and-place machine such as pick-and-place machine  32  of  FIG. 3  may bring component  20  into alignment with weft fiber  60 , as shown in  FIG. 10 . 
     Pick-and-place machine  32  may then solder contact  78 B of component  20  to weft fiber  60  using solder  76 B, as shown in  FIG. 11 . Solder  76 B may have a first melting temperature T 1  (e.g., 180° C. or other suitable temperature). 
     After component  20  has been soldered to weft fiber  60  using contact  78 B, reed  55  may be moved (e.g., rotated) in direction  56  to press weft fiber  60  in place between warp fibers  40 - 1  and  40 - 2 , as shown in  FIG. 12 . As reed  55  moves, component  20  may rotate freely in response to any rotation of the weft fiber  60  to which component  20  is attached. 
     As shown in  FIG. 13 , reed  55  may then be moved in direction  57  and needles  48 - 1  and  48 - 2  may be moved to switch the locations of warp fibers  40 - 1  and warp fibers  40 - 2 . As the warp fibers swap locations, the warp fibers adjacent to component  20  are received within warp fiber grooves  96  and  96 ′ on the upper surface of package  90 , thereby locking component  20  in place within fabric  62 . To secure component  20  and complete the electrical coupling process, pick-and-place machine  32  may solder contact  78 A to the warp line in groove  96  using solder  76 A (and, if desired, may form a solder connection to the warp line in groove  96 ′ using a real contact or a dummy contact at the opposing end of package  90 ). Solder  76 A may have a second melting temperature T 2  (e.g., 160° C. or other suitable temperature). Melting temperature T 2  may be lower than melting temperature T 1 , so the soldering operations used in forming the second solder joint for the warp fiber(s) do not disrupt the previously formed solder joint for the weft fiber. 
     Once warp fiber soldering operations have been completed, weaving can continue by passing weft fiber  60  back through warp fibers  40 - 2  and  40 - 1 , as shown in  FIG. 14 . 
     Any suitable number of components  20  may be soldered to fabric  62  using pick-and-place machine  32  (e.g., one, two or more, ten or more, one hundred or more, one thousand or more, less than 5,000, 1000-100,000, more than 500,000, etc.). The components that are soldered to fabric  62  may all be of the same type or a mixture of different types of components may be used. 
     Illustrative steps involved in forming fabric  62  using operations of the type shown in  FIGS. 9, 10, 11, 12, 13, and 14  are shown in the flow chart of  FIG. 15 . 
     At step  120 , weft fiber  60  may be inserted between warp fibers  40 - 1  and  40 - 2  using shuttle  58  in weaving machine  30 . 
     At step  122 , pick-and-place machine  32  may solder component  20  to weft fiber  60  using solder  76 B and contact  78 B (i.e., so that longitudinal axis  100  of package  90  runs parallel to weft fiber  60 ). 
     At step  124 , reed  55  pushes weft fiber  60  into place. Component  20  may rotate freely with any rotation of fiber  60 . 
     At step  126 , the positions of warp fibers  40 - 1  and  40 - 2  are swapped. As part of this process, one or more of the warp fibers are received within the groove structures or other guiding structures formed in package  90  of component  20 . Pick-and-place machine  32  solders one or more warp fibers to component  20 . For example, the warp fiber  40 - 1  in groove  96  may be soldered to contact  78 A using solder  76 A. Solder  76 A may have a lower melting point than solder  76 B, so that the solder joint that was formed with solder  76 B will not be disrupted while forming the solder joint with solder  76 A. 
     Weaving may then continue, as illustrated by line  128  of  FIG. 15 . 
     If desired, other arrangements may be used for securing conductive fibers in fabric  62  to contacts in component  20  (e.g., crimped metal tabs, holes lined with metal contacts, grooves that run across package  90  diagonally or with other configurations, mating parts in package  90  that clamp onto conductive fiber, etc.). Some fibers may overlap package  90  and may help to hold package  90  and components  20  in place within fabric  62 . A configuration that may be used for package  90  in this type of arrangement is shown in  FIG. 16 . 
     Package  90  of component  20  of  FIG. 16  has first groove  96 - 1  and second groove  96 - 2 , each of which may have a respective electrical contact for component  20 . Grooves  96 - 1  and  92 - 2  may be parallel grooves or other fiber guiding structures that are formed on opposing ends (sides) of component  20  and that are configured to receive respective conductive fibers in fabric  62  (e.g., warp or weft fibers). 
       FIG. 17  is a top view of electrical component  20  of  FIG. 16  in an illustrative configuration in which a first warp fiber  40 A among warp fibers  40  has been soldered to a contact in groove  96 - 1  and a second warp fiber  40 B has been soldered to a contact in groove  96 - 2 . Three warp fibers  40 E overlap package  90 . If desired, one warp fiber  40 E may overlap package  90  or more than two fibers  40 E may overlap package  90 . Warp fibers  40 E lie between fibers  40 A and  40 B and run parallel to fibers  40 A and  40 B. Fibers  40 E may be insulating fibers or conductive fibers. 
       FIG. 18  is a cross-sectional side view of component  20  of  FIG. 17  taken along line  130  and viewed in direction  132 . As shown in  FIG. 18 , warp fibers  40 E may help hold component  20  in place on top of weft fiber  60  in fabric  62  by forming a retention pocket for package  90 . 
     In general, components  20  may be embedded into fabric  62  during any suitable fiber intertwining operations (e.g., during weaving, knitting, braiding, etc.) using any suitable type of component mounting equipment and fiber intertwining equipment. The mounting equipment may include heating elements for melting solder, forming welds, curing adhesive, molding package  90 , etc., and/or may include mechanical equipment for screwing screws into package  90 , for crimping metal tabs, and otherwise mechanically processing components  20  (e.g., to form electrical connections with fibers). The mounting equipment may also include equipment for dispensing adhesive, for applying light (e.g., laser light), for manipulating fibers, etc. 
     As shown in the schematic diagram of  FIG. 19 , component  20  may have one or more contacts  78  that are electrically connected to one or more fibers  74  using one or more respective electrical connections  134 . Component  20  may have a body with any suitable shape (circular, oblong, spherical, box-shaped, pyramidal, etc.), may have a body formed from any suitable material (plastic, glass, ceramic, crystalline material, metal, fiber-based composites, etc.), and may contain any suitable electronic device or devices such as light-emitting components, integrated circuits, light-emitting diodes, light-emitting diodes that are packaged with transistor-based circuitry such as communications circuitry and/or light-emitting diode driver circuitry that allows each component to operate as a pixel in a display, discrete components such as resistors, capacitors, and inductors, audio components such as microphones and/or speakers, sensors such as touch sensors (with or without co-located touch sensor processing circuitry), accelerometers, temperature sensors, force sensors, microelectromechanical systems (MEMS) devices, transducers, solenoids, electromagnets, pressure sensors, light-sensors, proximity sensors, buttons, switches, two-terminal devices, three-terminal devices, devices with four or more contacts, etc. Electrical connections  134  may be formed using solder, conductive adhesive, welds, molded package parts, mechanical fasteners, wrapped fiber connections, press-fit connections, and other mechanical connections, or using any other suitable arrangement for forming an electrical short between conductive structures. 
     As shown in  FIG. 20 , component  20  may have a circular body that is connected to one or more fibers  74 . 
       FIG. 21  is a diagram of an illustrative component with a C-shape body that is coupled to fibers  74 . 
       FIG. 22  shows how body  90  of component  20  may have a square shape. 
       FIG. 23  shows how body  90  of component  20  may have a cross shape. 
       FIG. 24  shows how body  90  of component  20  may have a trapezoidal shape. 
     In the example of  FIG. 25 , body  90  has a shape with a combination of curved and straight edges. 
     Other shapes may be used for body  90  if desired. The examples of  FIGS. 20, 21, 22, 23, 24, and 25  are merely illustrative. Moreover, any number of fibers  74  may be coupled to any of these body types and/or components  20  of other shapes (e.g., one warp fiber and one weft fiber, two warp fibers and one weft fiber, two weft fibers and one warp fiber, multiple warp fibers, multiple weft fibers, three or more fibers of any time, fibers in a knitted or braided fabric, etc.). 
       FIGS. 26, 27, 28, 29, 30, 31, 32, and 33  are side views of illustrative components  20  (or portions of components  20 ) showing various connection arrangements (e.g., examples of connection  134  of  FIG. 19 ). 
       FIG. 26  is a side view of component  20  in a configuration in which contact  78  is formed of metal (e.g., a bendable metal tab) or other conductive material that forms a crimped electrical connection to fiber  74 . 
       FIG. 27  is a side view of component  20  in a configuration with a pair of crimped fiber connections are being made to fibers  74  and in which body  90  has a rounded edge profile. 
       FIG. 28  is a side view of an illustrative electrical component having a press-fit fiber connection. In this type of arrangement, fiber  74  is forced through narrow opening  160 , which causes portions  162  of body  90  to temporarily spread outward. When portions  162  relax in directions  164 , fiber  74  is pressed against contact  96 . 
     As shown in  FIG. 29 , body  90  may have two portions that are coupled using adhesive  140 , thereby trapping fiber  74  against contact  78  (i.e., component  20  may form a clamped-fiber connection to fiber  74 ). 
       FIG. 30  shows how body  90  may be molded around contact  78  and fiber  74  (e.g., using plastic molding equipment). Contact  78  may be, for example, a metal structure that is crimped onto fiber  74  during the fabric formation process. Molded connections of the type shown in  FIG. 30  may be formed by molding plastic in body  90  around fiber  74  or by otherwise using heat to cause plastic or other material to mold into a desired shape to form an electrical connection with fiber  74 . 
     As shown in  FIG. 31 , fasteners such as screw  142  may be screwed into body  90  to hold fiber  74  against contact  78 . 
     As shown in  FIG. 32 , laser light  146  or heat from another source may be used to weld fiber  74  (e.g., a metal fiber) onto contact  78 . Welded connections may be formed without using solder or may be combined with solder-based connection arrangements or other electrical connections. 
     In the illustrative arrangement of  FIG. 33 , one or more loops of fibers  74  are wrapped around body  90  against contact(s)  96 , thereby forming a wrapped-fiber electrical connection between fiber(s)  74  and component  20 . 
     If desired, additional types of connections may be used in coupling fibers  74  to components  20 . The arrangements of  FIGS. 26, 27, 28, 29, 30   31 ,  32 , and  33  are merely illustrative.
