     BACKGROUND 
     The amount of data transferred between and among electronic devices has increased tremendously. Applications such as high-definition video require huge amounts of data to be transferred at very high data rates. Unfortunately, high-speed communications between electronic devices have become so fast that simple cables consisting of two inserts connected by wires are no longer suitable. These simple cables degrade signals and cause skews such that high-speed data communication is not reliable. 
     Accordingly, new cables are needed. These cables may be active in that they include active electronic components, such as integrated circuits. These circuits consume power and thus create heat. This heat can degrade reliability of the cable and its circuitry, and can also be unpleasant for a user to touch. 
     These cables may experience forces and mechanical stress during use. Given their complexity, it may be useful to provide cables having increased strength. Also, given their complexity, problems with manufacturability may be a concern. 
     Thus, what is needed are circuits, methods, and apparatus for high-speed cables that can reliably convey signals in high-speed communications. The cable inserts may be able to transfer heat in a way to improve user experience and cable reliability. The cables may have increased strength. The cables and connector inserts may be arranged in such a way as to provide improved manufacturability. 
     SUMMARY 
     Accordingly, embodiments of the present invention may provide high speed connector inserts and cables having improved heat conduction, high strength, and may be manufactured in a reliable manner. 
     An exemplary embodiment of the present invention may provide a connector insert having improved heat conduction. This connector insert may include several paths by which heat may be removed from circuitry in the cable insert. In one example, heat may be removed from one or more circuits by forming a thermal path between the circuit, which may be an integrated circuit or other device, and a shield of the connector insert. This path may include a thermally conductive material to further reduce its thermal resistance. Another example may include one or more pads on a side of an integrated circuit board. These pads may be soldered directly to the shield, or otherwise thermally connected to the shield. 
     To improve heat conduction in another example, braiding surrounding a cable may be soldered or otherwise thermally connected to the shield. This connection may be covered by a cap to avoid electromagnet interference (EMI) leakage. This cap may be crimped to provide a robust mechanical connection. This crimping may be accomplished by applying force to the cap in multiple directions. In one specific embodiment of the present invention, force may be applied to the cap in four directions during crimping. The cap may be soldered to portions of either or both the connector insert and cable for improved heat conduction and mechanical reliability. 
     Another exemplary embodiment of the present invention may provide a cable having a high strength. To provide this increased strength, a braiding surrounding the cable or one or more of its conductors may include one or more types of fibers. For example, aramid fibers may be included in the braiding around the cable. To simplify soldering of the braiding, the aramid or other fibers may be bunched or grouped, such that they may be pulled out of the way. In various embodiments of the present invention, these fibers may be pulled out of the way using static electricity, or by other mechanisms. A specific embodiment of the present invention may use a braiding formed of counter-rotating spirals to assist in the separation of the aramid fibers. 
     Another exemplary embodiment of the present invention may provide for a reliable manufacturability. One specific example may align several pairs of twisted pairs of conductors in the cable using a wire comb. Specifically, a wire comb having a plurality of openings may be used to hold twisted pairs in an aligned manner. This may allow soldering of the cables to a printed circuit board or other appropriate substrate. In various embodiments of the present invention, this soldering may be accomplished in a reliable manner using a solder bar. 
     Various embodiments of the present invention may incorporate one or more of these and the other features described herein. A better understanding of the nature and advantages of the present invention may be gained by reference to the following detailed description and the accompanying drawings.

     DESCRIPTION OF EXEMPLARY EMBODIMENTS 
       FIG. 1  illustrates a side view of a connector plug according to an embodiment of the present invention. This figure, as with the other included figures, is shown for illustrative purposes and does not limit either the possible embodiments of the present invention or the claims. 
     Again, this plug may be part of an active cable for high-speed data communications. As such, it may include active circuitry, such as chip  140 , which consumes power and generates heat. This heat can reduce the reliability of the active circuitry and make for an unpleasant user experience if it becomes excessively hot. Thus, it is desirable to remove heat from this connector plug. Accordingly, embodiments of the present invention may provide several low thermal resistance paths to dissipate this heat. 
     This connector plug includes plug connectors  110 , which may mate with conductors of a connector receptacle (not shown). Plug connectors  110  may mechanically attach to printed circuit board  120 . These plug connectors  110  may electrically connect to chip  140  using traces on printed circuit board  120 . Plug connectors and chip  140  may connect to wires and cable  130  via traces on printed circuit board  120 . Housing  170  may be used to surround shield  150 . 
     Chip  140  may be an example circuit of many circuits that may generate the majority of heat in this plug. Again, embodiments of the present invention may employ several paths by which heat can be dissipated. In the first, heat can be removed from chip  140  directly to shield  150 . Accordingly, a thermal conductor layer  160  may be used to provide a thermal path from chip  140  to shield  150 . In a second path, chip  140  may attach to printed circuit board  120 , thereby allowing heat to flow into printed circuit board  120 . A solder area  180 , which may be on the side, bottom, or top of printed circuit board  120 , may be soldered to a portion of shield  150 , thereby creating a low thermal resistance path from the printed circuit board to the shield for heat dissipation. From the shield, head can dissipate out through the cable. In a specific embodiment of the present invention, a side of the printed circuit board  120  is plated and soldered to the shield. The heat thus travels from the chip to the printed circuit board, then to the shield via the edge plating, then to the cable via cable braiding. 
     In a third path, the cable (not shown) also provides a path for heat to leave this plug. As will be seen below, a braiding or other layer of the cable may be soldered or otherwise attached to shield  150 . This may allow head to dissipate through the cable. In other embodiments of the present invention, a low thermal path, which may include liquid, metal, or other material, may be included in the cable. 
     Plug conductors  110  may also provide a heat path into a device receptacle. The device receptacle may be designed to provide low thermal resistance paths to further aid in the dissipation of heat in the plug. 
     Again, much of the heat generated by active circuitry in the connector insert can be removed via conduction through the cable. An example of how this is done is shown in the following figures. 
       FIG. 2  illustrates a side view of a connection between cable  230  and connector insert shield  250 . Cable braiding  234  may be pulled away from cable  230  and soldered to shield  250  at solder locations  236 . Conductors (not shown) in cable  230  may connect to circuitry inside shield  250 . Housing  270  may surround portion of shield  250  to provide thermal insulation and the location for a user to grasp the connector insert. 
     As cable braiding  234  is separated from cable  230 , one or more openings  238  may form. For example, shield  250  may have a width greater than its height. Some or all of cable braiding  234  may attach to shield  250  along the width of shield  250 , thereby leaving opening  238  along the height (or side) of shield  250 . Opening  238  may provide a path for electromagnetic interference to be emitted from the cable conductors (not shown). Accordingly, embodiments of the present invention may employ a cap or other structure over the opening  238 . An example is shown in the following figure. 
       FIG. 3  illustrates a cap  339  that may be located over solder locations  236  between a cable braiding  234  and connector insert shield  250  consistent with embodiments of the present invention. Cap  339  may be formed of metal such as aluminum, stainless steel, or other material. During manufacturing, cap  339  may be placed over solder locations  236  and crimped to be held in place. Cap  339  may also be soldered to provide additional shielding and mechanical support. 
     Conventional techniques used to crimp caps, such as cap  339 , often smash the cap and distort it, thereby possibly damaging the cable. Accordingly, embodiments of the present invention may crimp cap  339  by applying forces in multiple directions. An example is shown in the following figure. 
       FIG. 4  illustrates a crimping technique employed by various embodiments of the present invention. In this particular example, force is applied in four directions by tool die  410  on cap  439 . These forces may crimp cap  439  in a highly symmetrical manner for improved yield, improved EMI isolation, and mechanical stability. Also, this technique may reduce asymmetric forces that cable  330  would otherwise experience, thereby reducing the chance of damage to interior conductors (not shown) in cable  330  during manufacturing. 
     In this particular embodiment of the present invention, force may be applied to cap  439  in four directions, though in other embodiments of the present invention, force may be applied in other numbers of directions, such as two, three, or more than four directions. 
     Again, embodiments of the present invention may provide a cable having a high strength. To provide this increased strength, a shield or braiding surrounding the cable or one or more of its conductors may include one or more types of fibers. For example, aramid fibers may be included in a shield or braiding around the cable. Unfortunately, aramid fibers may interfere with the soldering process outlined above. To simply soldering of the braiding, the aramid or other fibers may be bunched or grouped in the cable shield or braiding, such that they may be pulled out of the way during soldering. In various embodiments of the present invention, these fibers may be pulled out of the way using static electricity, or by other mechanisms. An example of such a cable is shown in the following figure. 
       FIG. 5  is a cross-section of a high-speed cable according to an embodiment of the present invention. This cable may include four twisted pairs  520  and four single wires  530 . Twisted pairs  520  may be used to carry differential signals, multiple single ended signals, power, ground, bias, control, status, or other types of signal, power, status, or control lines. Single wires  530  may be used to convey single ended signals, one side of a differential signal, power, ground, bias control, status, or other types of signal, power, status, or control lines. In other embodiments the present invention, cables consistent with embodiments of the present invention may include other numbers of twisted pairs and single wires. 
     In this example, twisted-pairs  520  and single wires  530  surround a nylon core  560 , which is used for mechanical support. In other embodiments of the present invention, nylon core  560  may be substituted by a wire, one or more fiber-optic lines, or other conductor or fiber. These connectors may be bound by shield tape  580 . 
     Shield braid  540  may surround the cable. Jacket  570  may surround shield braid  540  and provide mechanical support for the cable. Again, aramid fibers  550  may be dispersed or grouped in shield braid  540 . Shield braid  540  may be a conventional interwoven braiding, shield braid  540  may be formed of one or more counter-rotating spirals, or shield braiding  540  may be formed in other various ways. 
       FIG. 6  is a more detailed view of twisted pair  520  according to an embodiment of the present invention. Twisted pairs  520  may include two conductors  610  surrounded by insulation layer  630 . Spiral shield  620  may surround twisted-pair  520  and provides shielding against electromagnetic interference. Spiral shield  620 , like shield braid  540 , may be formed of braiding, one or more counter-rotating spirals, or other ways. Copper Mylar tape layer  670  may bind and provide mechanical support for spiral shield  620  and conductors  610 . 
     Again, embodiments of the present invention may employ one, two, or more counter-rotating spirals as a shield. An example is shown in the following figure. 
       FIG. 7  illustrates a side view of a portion of the cable according to an embodiment of the present invention. This figure illustrates a cable surrounded by jacket  710 . Jacket  710  has been cut away to reveal a first counter-rotating spiral  720  and a second counter-rotating spiral  730 . The first of these spirals may have an angle approximately equal to phi  740 . In a specific embodiment of the present invention, phi may be equal to 17 degrees. In other embodiments of the present invention, other angles may be used. The second of these may have approximately the same relative angle, shown here as negative phi  742  to indicate a different absolute direction. 
     In this way, during manufacturing, the wires in the counter-rotating spirals  720  and  730  may be easily peeled away, straightened, and soldered or otherwise electrically connected to locations in a connector plug. 
     Utilizing counter-rotating spirals  720  and  730  may also improve flexibility of the cable. For example, when the cable is twisted in a first direction, counter-rotating spiral  720  may tighten while counter-rotating spiral  730  may loosen. The tightening of counter-rotating spiral  720  may protect the internal conductors. Similarly, when the cable is twisted in a second direction, counter-rotating spiral  730  may tighten while counter-rotating spiral  720  may loosen. The tightening of counter-rotating spirals  730  may protect the internal conductors. 
     Again, one or more different types of fibers may be employed by embodiments of the present invention. These fibers may be interspersed singly or in groups in one or more of the counter-rotating spirals  720  and  730 . These fibers may be included for various reasons. 
     In a specific embodiment of the present invention, aramid fibers may be included for additional strength. Again, aramid fibers may interfere with soldering of the counter-rotating spirals  720  and  730  to locations such as a shield of, or pads in, a connector insert. Accordingly, in various embodiments of the present invention, these fibers may be pulled away from the wires in the counter-rotating spirals  720  and  730  by static electricity, air movement, or other methods. 
     The cable shown here may be made in a number of ways. In one, the wires and twisted pairs are pulled from spools and then wrapped in various layers for mechanical support. To improve reliability of the cable and reduce the chance of damage when the cable is used, the spools holding the wires and twisted pairs may be rotated during cable manufacturing. An example is shown in the following figure. 
       FIG. 8  illustrates the construction of a cable according to an embodiment of the present invention. In this example, a number of spools  810  may each hold one of the conductors  820 . As the cable is formed, spools  810  may rotate, thereby individually twisting the wires. Also, spools  810  may twist as a group, thus twisting the wires as a group. For example, spools  810  may twist one-half turn, one turn, two turns, or other fractions or numbers of turns per length of cable. This combined twisting action may be referred to as planetary wire feeding, or as a planetary twist. In other embodiments of the present invention, other types of assembly may be used. For example, a back twist, or no twist, may be used. The various conductors may be bound together, for example using tape  825 . A jacket may be extruded at  830 , thus sealing the wires. 
     Spools  810  may hold various types of conductors or groups of conductors. For example, they may hold single conductors, coaxial cables, twisted pairs or shielded twisted pairs, or other types of conductors or groups of conductors. In a specific embodiment of the present invention, the conductors on one or more spools  810  are grouped in pairs, referred to as twinaxial, or twinax cables. 
     Again, cables according to embodiments of the present invention may include a number of twisted pairs  520  and single wires  530 , as shown in  FIG. 5 . The wires may connect to a printed circuit board in a connector insert, such as printed circuit board  120  in  FIG. 1 . However, twisted pairs  520  may emerge from an end of the cable in any orientation. As such, it may be difficult to solder the twisted pairs  520  to printed circuit board  120 . Accordingly, embodiments of the present invention may employ a wire comb to align the twisted pairs  520  in order to simplify soldering to printed circuit board  120 . Use of such a comb may improve the manufacturability of connector inserts according to embodiments of the present invention. An example of such a wire comb is shown in the following figure. 
       FIG. 9  illustrates a wire comb  910  that may be used to align twisted-pairs emerging from a cable according to an embodiment of the present invention. Wire comb  910  may include a plurality of non-circular openings  920  and circular openings  930 . Twisted pairs  520  may be untwisted to the point where they fit in openings  920 , then passed through openings  920 . Single wires  530  may be passed through openings  930 . In this way, connectors from a cable may be aligned as they emerge from wire comb  910 . This allows the conductors to be soldered to printed circuit board  120 , as shown in the following figure. 
       FIG. 10  illustrates a plurality of conductors  1010  that may be soldered to solder pads  1040  and  1070  on a printed circuit board, such as printed circuit board  120 . Specifically, connectors  1010  are covered by jacket  1020 . Jacket  1020  may be removed thereby exposing braiding or shield layers  1030 . Shield layers  1030  may be soldered to pads  1040 . An internal isolation layer  1050  may be stripped away leaving connector terminals  1060 , which may be soldered to pads  1070 . 
     Once conductors  1010  are aligned, it may be desirable to be able to solder shield layers  1030  to pads  1040  and connectors  1060  to pads  1070  in a reliable manner. Accordingly, embodiments of the present invention may employ a shaped solder bar during the soldering process. An example is shown in the following figure. 
       FIG. 11  illustrates a method of soldering conductors to a printed circuit board according to an embodiment of the present invention. In this example, twisted-pair conductors  1120  are to be soldered to pads on a printed circuit board  1130 . A shaped solder bar  1140  may be placed over connectors  1120 . Hot bar  1110  may be heated, for example by passing a current from one end to another. Hot bar  1110  may be lowered such that solder bar  1140  is heated and flows, thereby soldering a shield layer of twisted pair is  1120  to pads on printed circuit board  1130 . In this example, hot bar  1110  may include recesses  1150  such that solder bar  1140  is evenly heated. This configuration may provide a reliable solder connection between a shield braid of twisted-pair  1120  and a pad on printed circuit board  1130 . 
       FIG. 12  illustrates a connector insert according to an embodiment of the present invention. This connector insert includes an insert portion  1210  to fit in a compliant connector receptacle. Housing  1220  may be included such that a user can manipulate the connector insert. Stress relief and cable  1230  are also included for illustrative purposes. 
       FIG. 13  illustrates an exploded view of a connector insert according to an embodiment of the present invention. Conductors of cable  1305  pass through wire comb  1140  as described above. These conductors attach to printed circuit board  1350 . One or more circuits  1355  may be located on printed circuit board  1350 . Contacts  1365  may be supported by structure  1360 , and attach to printed circuit board  1350 . Frame portions  1310  and  1312  may encapsulate printed circuit board  1350  and active circuitry  1355 . Housing portions  1332  and  1320  may form a housing around the connector insert. A dust shield  1370  may be provided to protect the connector insert during transport and shipment. 
     The above description of embodiments of the invention has been presented for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form described, and many modifications and variations are possible in light of the teaching above.
