No. 12/854,180, filed Aug. 11, 2010, which is a divisional of U.S. patent application Ser. No. 12/571,376, filed Sep. 30, 2009, which are incorporated by reference. 
    
    
     BACKGROUND 
     Data transfers between devices such as computers and peripheral devices, including portable media devices, have become ubiquitous the last several years. Music, phone numbers, video, and other data are moved among these devices, often using universal serial bus (USB), FireWire™, DisplayPort™, or other types of cables. Such cables are used to form electrical pathways for signals that carry this information. 
     These electrical connections are typically formed by inserting connector inserts on each end of a cable into connector receptacles located on the computer and peripheral device. The connector receptacles are often formed using a metal housing to limit the propagation of stray signal components that would otherwise interfere with other signals. 
     The metal housing is typically stamped to form fingers. These fingers are then bent to form finger contacts. These finger contacts form an electrical connection with a shield on the connector insert and hold the connector insert when it is placed in a connector receptacle. However, these finger contacts may have sharp edges or burrs that may result during the stamping process. These edges or burrs can scratch or otherwise mar a connector insert after many insertions into a connector receptacle. Also, it is desirable that these finger contacts provide a secure snap or feel when accepting an insert. This provides the user with a mechanical feedback, letting her know that a connection has been made. 
     These connector receptacles are conventionally made separately, and out of a different material, than the enclosure that otherwise encompasses the computer or portable media player. This results in a seam that is formed near the opening of a connector receptacle at the interface of the receptacle and computer or peripheral device enclosure. These seams can become increasingly pronounced during the lifetime of the device after repeated stresses caused by connector insert insertions and the pulling of cables when inserted into the receptacle. These seams can be an unwanted blemish on an otherwise aesthetically-pleasing device. 
     Thus, what is needed are structures, methods, and apparatus that provide connector receptacles having a reduced tendency to scratch and otherwise cause wear to connector inserts. It is also desirable that such receptacles provide a secure tactile response when an insert is inserted. It is also desirable to provide connector receptacles having a pleasing appearance. 
     SUMMARY 
     Accordingly, embodiments of the present invention provide structures, methods, and apparatus for connector receptacles that have a reduced tendency to scratch and otherwise cause wear to connector inserts, have an improved tactile response when connector inserts are inserted, and have an aesthetically desirable appearance. 
     Various embodiments of the present invention can reduce scratches and wear by utilizing domes, cylinders, spheres, or other structures as receptacle housing finger contacts. A specific embodiment of the present invention may utilize a dome-shaped indentation in a frame of a connector receptacle. The frame may be made of metal or other material. The dome-shaped indentations may be arranged to fit into slots in a connector insert to provide a secure fit between the connector insert and connector receptacle. The domes can provide a surface that is substantially free from edges and burrs that would otherwise scratch or mar the surface of an insert, thereby causing wear. The domes may be located on a flexible frame that can expand to fit over a receptacle housing. These flexible frames may be conductive and grounded to provide electromagnetic impulse (EMI) shielding, thereby protecting circuitry in the computer, peripheral device, portable media player, or other device enclosed within the connector receptacle. The flexible frames may also be further at least partially enclosed by a second conductive frame for further EMI shielding and for overheating and fire reasons. The dome-shaped indentation may be made by stamping or other appropriate process. 
     Another specific embodiment of the present invention reduces scratches by utilizing cylindrical disks as finger contacts. These hockey-puck-shaped disks may be arranged to fit into slots in the connector inserts to provide a secure fit when a connector is inserted into a connector receptacle. The disks can provide a surface that is easily manufactured and reduces marring. The disks can be attached to a flexible frame that can expand to fit over a receptacle housing. As before, the frames can be grounded for shielding and they can be further shielded with a second conductive frame. The disks may be soldered or otherwise affixed to the flexible frame. 
     Another specific embodiment of the present invention reduces scratches and wear by employing spheres as finger contacts. These balls or spheres may be free to rotate when a connector insert is inserted into a connector receptacle. These spheres may be located in openings in a connector receptacle housing that are arranged such that the balls fit into slots in the connector inserts when inserted into a connector receptacle to provide a secure fit. The spheres may be held in place by a flexible frame that can expand to fit over the spheres and receptacle housing. Since the spheres are free to rotate when an insert is inserted, they can provide a low resistance but secure feel to a user. As before, the frames can be grounded for shielding and they can be further shielded with a second conductive frame for further EMI and overheating and fire protection. The spheres may be held in place by a vacuum or other pressure differential, by magnetic fields, or by other means, while the flexible frame is put in place. In other embodiments of the present invention, other shapes besides domes, cylinders, and spheres may be used. For example, other spheroid shapes may be used, and they may be fixed, that is, attached to or formed from a frame. These spheroids may be free to turn, rotate, twist, or otherwise move when a connector insert is inserted in a connector receptacle. 
     Various embodiments of the present invention can provide aesthetically-pleasing receptacle housings by forming receptacle housings using the same type of material, or material having the same or similar color or texture, as is used for the enclosure for the electronic device that includes the receptacle. In one specific embodiment of the present invention, a receptacle housing can be formed using plastic. To reduce EMI interference, the plastic receptacle housing can be at least partially enclosed in a conductive frame. The frame may have the above domes, cylinders, or balls, or other shaped EMI contacts to form an electrical path with a shield on a connector insert that is inserted into the connector receptacle. The frame may be flexible to fit around the receptacle housing. The frame may be enclosed in a second conductive frame for further EMI protection and for heat and fire reasons. The connector receptacle can then be connected to a flexible or printed circuit board and aligned with a matching opening in the electronic device. 
     Other embodiments of the present invention can provide an aesthetically-pleasing receptacle housing by forming receptacle housings that may be, at least in part, contiguous with an enclosure containing an electronic device that also includes the connector receptacle. In a specific embodiment of the present invention, a portion of the connector receptacle near its opening may be formed contiguously with, that is, may be formed as part of, the device enclosure. Other portions away from the opening may be formed separately. As before, at least part of the receptacle housing may be enclosed in a conductive frame. The frame may have domed, cylindrical, spherical, or other shaped finger contacts. The frame may be flexible to fit around the receptacle housing. This frame may be enclosed in a second conductive frame. 
     Other embodiments of the present invention provide an aesthetically pleasing connector receptacle housing by forming receptacle housings that can be contiguous with the enclosure containing the electronic device that also includes the receptacle, that is, they can be formed as part of the enclosure. A specific embodiment of the present invention further forms a tongue as part of the connector receptacle and device enclosure. Conductive contacts may then be placed on the tongue to form electrical paths with contacts in a connector insert. As before, at least part of the receptacle housing may be enclosed in a conductive frame. The frame may have domed, cylindrical, ball, or other shaped EMI contacts. The frame may be flexible to fit around the receptacle housing. This frame may be enclosed in a second conductive frame. 
     In various embodiments of the present invention, the connector receptacle may be a USB, DisplayPort, IEEE 1394 (FireWire), Ethernet, or other type of connector receptacle. The connector receptacle housings can be formed from the same material used to form the enclosure for the device that includes the connector receptacle. These materials can include aluminum, plastic, ceramics, or other material. The frames, disks, spheres, and other components can be formed using conductive or nonconductive materials, such as aluminum, brass, steel, stainless steel, spring steel, palladium nickel alloy, copper, and other materials. These materials may be plated, for example, they may be palladium-nickel plated, or plated with other appropriate materials. For example, the spheres may be palladium-nickel plated. Connector receptacle consistent with embodiments of the present invention may be located on computer enclosures or other enclosures, such as those used for desktop computers, laptop computers, netbook computers, media players, portable media players, tablet computers, cell phone, or other electronic devices. 
     Another embodiment of the present invention may provide a connector receptacle having a simplified housing. Specifically, this connector receptacle may include a housing where a portion of the housing has been omitted to save space. In various embodiments of the present invention, various portions of the housing may be omitted. For example, this portion may be a top of a connector receptacle housing, such that its absence is not particularly noticeable to an observer. Removing the top of the housing may reduce the height of the connector receptacle in order to save space in a device housing the connector receptacle. 
     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 ILLUSTRATIVE EMBODIMENTS 
       FIG. 1  illustrates a computer system that is improved by the incorporation of embodiments of the present invention. This figure shows an example of a computer system  100  that includes computer enclosure  110 , computer monitor  120 , keyboard  130 , and mouse  140 . Monitor  120 , keyboard  130 , and mouse  140  may connect to computer enclosure  110  via cables. For example, computer monitor  120  is shown as being connected to computer enclosure  110  via cable  167 . Keyboard  130 , mouse  140 , and other devices may be connected to computer enclosure  110  via cables such as cable  157 . 
     Cables  157  and  167  can include connector insert housings  155  and  160 . Insert housings  155  and  160  allow a user to hold the end of the cable and insert a connector insert, such as connector insert  150 , into connector receptacle  170  on computer enclosure  110 . 
     Embodiments of the present invention may be employed to improve connector receptacles such as connector receptacles  165  and  170 . These connector receptacles may be compatible with USB, FireWire, DisplayPort, Ethernet, and other types of signaling and power transmission standards. These connector receptacles may be compatible with proprietary signaling and power transmission technologies. Also, as new signaling and power transmission standards and proprietary technologies are developed, embodiments of the present invention may be used to improve connector receptacles consistent with those standards and technologies. The connector receptacles may be located on computer enclosures, such as computer enclosure  110 , or other enclosures, such as those used for desktop computers, laptop computers, netbook computers, media players, portable media players, tablet computers, cell phone, or other electronic devices. 
     These connector inserts are typically shielded with metal for signal integrity purposes. The shielding on the connector inserts make electrical contact with metallic finger contacts on the connector receptacle housing to form an electrical connection. Typically, the connector receptacle housing is connected to ground inside computer enclosure  110 . 
     These conventional connector receptacle finger contacts may have sharp edges or burrs that can scratch or mar connector inserts as they are inserted into a connector receptacle. This can lead to undesirable wear and a diminished appearance. Accordingly, various embodiments of the present invention provide finger contacts that reduce wear on connector inserts. Some examples are shown in the following figures. 
       FIGS. 2A-2C  illustrate top, side, and front views of a frame for a connector receptacle according to an embodiment of the present invention. These figures, as with the other included figures, are shown for illustrative purposes and do not limit either the possible embodiments of the present invention or the claims. 
     These figures show a frame  200  that may be used alone or in conjunction with a connector receptacle housing to form a connector receptacle according to an embodiment of the present invention.  FIG. 2A  illustrates a top view of frame  200 . Frame  200  includes base area  215  that provides mechanical support for fingers  210 . Fingers  210  can each have a dome-shaped finger contact  220 .  FIG. 2B  illustrates a side view, and  FIG. 2C  illustrates a front view of frame  200 . In various embodiments of the present invention, fingers  210  can be made comparatively wide. This reduces series resistance and improves EMI performance. This is particularly true in comparison to conventional stamped fingers. 
     Frame  200  and finger contacts  220  can be formed of metal or other material. Frame  200  and finger contacts  220  can be formed of the same type of metal or other material, or they may be formed of different materials. For example, frame  200  and fingers  210  may be formed of a flexible metal to allow the insertion of connector inserts, while finger contacts  220  may be made of a harder, more durable material. Frame  200  may be formed using steel, stainless steel, aluminum, palladium-nickel alloy, or other material. Frame  200  may also be plated. For example, frame  200 , or portions of frame  200 , such as the finger contacts  220 , may be palladium-nickel plated. Finger contacts  220  may be made by forming divots or depressed areas in fingers  210 . Alternately, they may be formed by attaching dome-shaped protrusions to fingers  210 . Finger contacts  220  may have a dome shape, or they may have other shapes. For example, they may have other rounded or contoured, or other types of shapes. These rounded shapes are substantially free of edges and burrs, and therefore limit the scratches they impart to connector inserts as they are inserted. 
       FIGS. 3A-3B  illustrate the reaction of a receptacle frame  300  consistent with an embodiment of the present invention as an insert  350  is inserted. Specifically, in  FIG. 3A , as connector insert  350  is inserted, fingers  310  deform to provide space in connector receptacle frame  300 . In  FIG. 3B , when connector insert  350  is fully inserted in connector receptacle frame  300 , dome-shaped finger contacts  320  fit into slots  340  in connector insert  350 . This allows fingers  310  of connector receptacle frame  300  to spring back into place. Having finger contacts  320  inside cutouts  340  of insert  350  provides mechanical stability for connector insert  350  and helps to prevent accidental extraction from connector receptacle frame  300 . 
     In this way, as connector insert  350  is inserted into connector receptacle frame  300 , connector insert  350  comes in contact with finger contacts  320 . Since finger contacts  320  are dome-shaped and substantially free from sharp edges or burrs, connector insert  350  can experience less wear and tear than it would with a conventional connector receptacle. 
     Again, frame  300  may be used in conjunction with a connector receptacle housing formed of plastic or other material. The receptacle housing may be a dedicated housing. That is, it may be separate from the device enclosure that contains the connector receptacle. In another embodiment of the present invention, some or all of the receptacle housing may be formed as part of the device enclosure. For example, frame  300  may be used in conjunction with a receptacle housing and tongue that are both formed as part of a device enclosure that contains the connector receptacle. The receptacle housing and device enclosure may be made of plastic, ceramic, aluminum, or other material. One example of how frame  300  may be used in conjunction with a plastic receptacle housing is shown in the following figure. 
       FIGS. 4A-4B  illustrate connector receptacles according to an embodiment of the present invention.  FIG. 4A  illustrates a connector receptacle including a connector receptacle housing  430  that is partially covered by frame  400 . Connector receptacle housing  430  may be formed of plastic, ceramic, or other material. Frame  400  may be made of metal or other material. Frame  400  includes a number of fingers  410 , each having a finger contact  420 . As before, finger contacts  420  may be dome-shaped. In other embodiments of the present invention, they may have other shapes as appropriate to reduce connector insert wear. 
     Again, employing figure contacts  420  reduces wear on connector inserts that otherwise can occur after several insertions into a connector receptacle. This improves the long-term appearance of the connector inserts. It is also desirable to reduce the visible wear that degrades the appearance of the connector receptacle. Accordingly, various embodiments of the present invention provide raised areas in a connector receptacle. These raised areas experience wear instead of the other portions of the connector receptacle housing. Since these raised areas may be set back from the front of a connector receptacle, they may experience wear and protect the front areas of the connector receptacle, thereby improving the long-term appearance of the connector receptacle. In various embodiments of the present invention, the opening of the connector receptacle is made larger to account for the raised areas. In this way, the size of the opening of the connector receptacle can be made compliant with appropriate signal or power transmission standards when the raised areas are employed. 
     These raised areas can be located around the finger contact areas in a connector receptacle, or they may be located in other areas inside a connector receptacle. In a specific embodiment of the present invention, two raised areas are included, one on the top and one on the bottom of the inside of the connector receptacle. Each raised area surrounds two finger contacts. In another embodiment of the present invention, additional raised areas are located on the sides of a connector receptacle. These additional raised areas may also surround finger contacts on the sides of a connector receptacle. The raised areas may be made of the same material as the connector receptacle housing, or they may be made of a different material. 
     In the specific example shown in  FIG. 4A , raised areas  440  are used. These raised areas can wear first, thus protecting the rest of the connector receptacle. 
     Again, as a connector insert (not shown) is inserted into the connector receptacle, fingers  410  deflect or open up, thereby allowing a connector insert to be inserted. Finger contacts  420  mate with cutouts on the connector insert (not shown), allowing fingers  410  to return to position when the insert is fully engaged. Frame  400  and fingers  410  may be formed of a flexible metal or other material having a spring-like quality, such that fingers  410  can deflect and return to their original position. Fingers  410  and finger contacts  420  may be made of the same material or they may be made of different materials. For example, finger contacts  420  may be made of a more durable material than fingers  410  in order to enhance the lifetime of the connector receptacle, while providing fingers  410  having the desired flexibility. 
     In these examples, six fingers  410  are shown. In other embodiments of the present invention, other number of fingers may be used. For example, four fingers may be used, two on a top and two on a bottom of a connector receptacle frame. In some embodiments of the present invention, it may be desirable to provide reinforcement for fingers  410 . For example, such a reinforcement could increase the hold of finger contacts  420 , thereby reducing the likelihood of accidental extraction of a connector insert. Accordingly, in some embodiments of the present invention, a shell is provided around frame  400 . A shell can be used to increase resistance to fire caused by excessive heat buildup at the connector contacts, provide additional electromagnetic interference shielding, and provide additional mechanical support for the connector receptacle. An example is shown in  FIG. 4B . 
       FIG. 4B  illustrates a connector receptacle having an additional shell  450  according to an embodiment of the present invention. Shell  450  may be metallic, ceramic, or formed of other material. In this example, shell  450  includes fingers  435 . These fingers  435  allow movement of fingers  410  on frame  400 , thereby allowing deflection of fingers  410  when a connector insert is inserted and removed. 
     In an embodiment of the present invention, dome-shaped or other shaped finger contacts are used to reduce wear when a connector insert is inserted into a connector receptacle housing. In other embodiments of the present invention, spheres or balls are used as finger contacts. This allows the finger contacts to rotate when an insert is inserted into a connector receptacle. Since these spheres rotate, they present a new surface to the connector inserts as they are inserted. This prevents wear on the spheres that could eventually mar a connector insert. They also provide a smooth feeling to a user when the user is inserting a connector insert. An example is shown in the following figure. 
       FIGS. 5A-5C  illustrate a connector receptacle incorporating finger contact spheres according to an embodiment of the present invention.  FIG. 5A  illustrates a connector receptacle housing  530  having openings or holes  532  into which spheres  520  are placed.  FIG. 5B  illustrates a frame  500  having fingers  510 , each having an opening  522  in which sphere  520  can fit when frame  500  is placed over connector receptacle housing  530 . 
     During assembly, spheres  520  can be held in place in connector receptacle housing  530 , while frame  500  is fitted over connector receptacle housing  530 . For example, spheres  520  can be held in place by a vacuum. In a specific embodiment of the present invention, connector receptacle housing  530  is placed in a quantity of spheres  520 . A vacuum is created in the connector receptacle housing  530 , thereby drawing spheres  520  into openings in connector receptacle housing  530 . While spheres  520  are held in place, frame  500  can be fitted over spheres  520  and housing  530 . Again, openings  522  in fingers  510  of frame  500  fit over spheres  520  holding them in place in connector receptacle housing  530 . In another specific embodiment of the present invention, spheres  520  are held in place during assembly by magnetic attraction. For example, a magnetic field is generated around connector receptacle housing  530 , thereby drawing spheres  520  into openings in connector housing  530 . Spheres  520  are magnetically held in place while frame  500  is placed over connector receptacle housing  530 . 
       FIG. 5C  illustrates top, side, and front views of a connector receptacle employing spheres  520  as finger contacts according to an embodiment of the present invention. Spheres  520  fit into openings in connector housing  530 . Openings  522  in fingers  510  hold spheres  520  in place. Frame  500  and spheres  520  may be formed using steel, stainless steel, copper, palladium-nickel alloy, aluminum, brass, or other material. They may also be plated. For example, they may be palladium-nickel plated. 
       FIGS. 6A-6B  illustrate the reaction of a connector receptacle employing spheres as finger contacts according to an embodiment of the present invention as an insert is inserted. In  FIG. 6A , fingers  610  can deflect or open to allow insert  650  to be inserted into connector receptacle housing  630 . As connector insert  650  is inserted, spheres  620  rotate. This rotation allows a new surface to be presented to connector insert  650 , thereby reducing wear on connector insert  650 . In  FIG. 6B , connector insert  650  is fully engaged in connector receptacle housing  630 . Spheres  620  fit in connector insert cutouts  640 , thereby providing the tactile resistance to the extraction of connector insert  650 . 
     In this example, spheres or balls are used as finger contacts. In other embodiments of the present invention, other shapes, such as cylinders, may be used. A more detailed example illustrating the use of spheres as finger contacts is shown in the following figures. 
       FIGS. 7A-7B  illustrate a connector receptacle employing spheres as finger contacts according to an embodiment of the present invention. In  FIG. 7A , spheres  720  can fit into openings in connector receptacle housing  730 . In  FIG. 7B , a frame  700  can be fitted over connector receptacle housing  730 . Openings in fingers  710  fit over spheres  720 , holding them in place. A flexible circuit board  740  or other connection may be used to form electrical pathways between connector receptacle contacts  750  and other electronic circuitry in the device (not shown.) While in this example a flexible circuit board  740  is shown, in this and the other included examples, connector receptacles according to embodiments of the present invention may be attached to flexible circuit boards, printed circuit boards, or other types of conductive pathways. 
     Again, a connector receptacle housing, such as connector housing  730 , may be a separate piece of material, such as plastic, ceramic, or aluminum, from the enclosure of a device which houses the connector receptacle. In other embodiments of the present invention, all or some of the connector receptacle housing may be formed as part of a device enclosure. These device enclosures can house or enclose desktop, laptop, notebook, netbook, media players, portable media players, cell phones, or other types or electronic devices. Some examples of portions of connector receptacles that are consistent with embodiments of the present invention are shown in the following figures. 
       FIGS. 8A-8C  illustrate examples where a portion of a connector receptacle housing may be formed as part of a device enclosure according to embodiments of the present invention. Incorporating at least a portion of the connector receptacle housing with a device enclosure allows the connector receptacle to visually appear as substantially integrated with the device enclosure and provides an aesthetically pleasing appearance. In  FIG. 8A , a portion  820  of a connector receptacle can be formed with device enclosure  810 . This provides a desired appearance, while being relatively easy to manufacture. 
     In  FIG. 8B , a substantial portion of recess  850 , which may include sidewall  852  and bottom surface  854 , of the connector receptacle housing can be formed with device enclosure  840 .

In  FIG. 8C , connector receptacle housing  880 , which may include sidewall  852 , bottom surface  854 , and connector receptacle tongue  890 , may be integrally formed as part of device housing  870 . In other embodiments of the present invention, other portions of a connector receptacle may be integrally formed with a device enclosure. These three example options are shown in the following figures. 
       FIGS. 9A-9C  illustrate connector receptacle portions that may be integrated with a device enclosure according to embodiments of the present invention. In  FIG. 9A , a front portion  910  of a connector receptacle housing can be formed as a part of a device enclosure. This particular level of integration of connector receptacle housing with the device enclosure can be referred to as partial integration. When viewed from the front of the connector receptacle, the connector receptacle housing appears to be at least partially seamlessly integrated within the device enclosure. This provides an attractive appearance to the device. While a seam or part of a seam between the device enclosure and receptacle housing may be observable in some embodiments with this level of partial integration, this partial integration can be comparatively easy to manufacture. 
       FIG. 9B  illustrates a portion of a connector receptacle housing that may be formed as part of the device enclosure according to an embodiment of the present invention. This embodiment provides a more seamless appearance between the device enclosure (not shown) and connector receptacle housing  920 . 
     In  FIG. 9C , a connector receptacle portion  940  including a tongue (not shown) may be formed in connector receptacle housing  930  as part of a device enclosure (not shown.) Various steps in a manufacturing processes that incorporate the above portions of a connector receptacle housing are shown in the following figures. 
       FIGS. 10A-10C  illustrate a partially-integrated connector receptacle housing according to an embodiment of the present invention at various times during a manufacturing process. In  FIG. 10A , a front portion  1010  of a connector receptacle housing may be formed as part of a device enclosure (not shown.) In  FIG. 10B , a connector receptacle  1020 , which may be the connector receptacle of  FIG. 4B , is provided. In  FIG. 10C , connector receptacle  1020  may be fitted to an opening in connector receptacle portion  1010 . As seen from the front, the connector receptacle housing appears to be at least partially integrated with the device enclosure, thereby providing an improved appearance. 
       FIGS. 11A-11D  illustrate a connector receptacle housing that can be formed with a device enclosure according to an embodiment of the present invention at various times during a manufacturing process.  FIG. 11A  illustrates a connector receptacle housing  1110  that may be formed along with a device enclosure (not shown.) In  FIG. 11B , spherical finger contacts  1120  may be placed in openings in connector receptacle housing  1110 . In  FIG. 11C , a back portion of the connector receptacle including tongue  1170 , contacts  1150 , and frame  1140 , including fingers  1130 , may be assembled. This assembly, in this example, can then be connected to a flexible circuit board  1160 . 
     In  FIG. 11D , frame  1140  may be inserted over connector receptacle housing  1110 . Fingers  1130  deflect over spheres  1120 . Spheres  1120  may be held in place by holes in fingers  1130 . Contacts  1150  can be made available to flexible circuit board  1160  for connection to circuitry inside the device (not shown.) 
       FIGS. 12A-12F  illustrate another connector receptacle housing that may be formed with a device enclosure according to an embodiment of the present invention at various times during a manufacturing process.  FIG. 12A  illustrates a connector receptacle housing  1210  that can be formed as a portion of a device enclosure (not shown.)  FIG. 12B  illustrates a frame  1220  including finger contacts  1225 . The finger contacts  1225  in this example are cylinders. These cylinders may be riveted or otherwise attached to frame  1220 . In other embodiments, other types of finger contacts may be used. For example, domes or spheres may be used. Frame  1220 , in this example, can be designed to spread such that it may be fitted over connector receptacle housing  1210 . As before, finger contacts  1225  may be made of a different material from frame  1220 . For example, finger contacts  1225  may be made of a harder material than that used to form frame  1220 . In  FIG. 12C , frame  1220  can fit over connector receptacle housing  1210 . 
     Again, in some embodiments of the present invention, it is desirable to enclose frame  1220  in a shield. In this example, shield  1230  can be fit over frame  1220  and connector receptacle housing  1210  in  FIG. 12D . 
     In  FIG. 12E , connector receptacle tongue  1240  and contacts  1250  may be connected to a flexible circuit board  1260 . In  FIG. 12F , this assembly may be inserted into connector receptacle housing  1210 , thereby forming the connector receptacle. 
     In various embodiments of the present invention, it is desirable to integrate connector receptacle tongue  1240  as part of connector receptacle housing  1210 . An example of this is shown in the following figure. 
       FIGS. 13A-13D  illustrate a connector receptacle housing and tongue that may be formed with a device enclosure according to an embodiment of the present invention at various times during a manufacturing process.  FIG. 13A  illustrates a connector receptacle  1310  having a back portion  1315  and a tongue (not shown) that are formed as part of a device enclosure (not shown.) In  FIG. 13B , a shield  1330  can be attached via contacts  1335  to a flexible circuit board  1340 . In  FIG. 13C  this assembly may be fit to connector receptacle housing  1310 . Specifically, shield  1330  may be fit over connector housing  1310 .  FIG. 13D  illustrates a front view of the completed connector receptacle housing. 
     In this and the above examples, the finger contacts may have spherical, domed, cylindrical, or other shapes. These finger contacts reduce wear of connector inserts, provide a proper tactile response to the user, and provide mechanical security when connector inserts are inserted. Again, it is also desirable to reduce wear on the connector receptacle itself. As before, various embodiments of the present invention provide connector receptacles having one or more wear surfaces  1370 . 
     These wear surfaces may be used in conjunction with the other embodiments shown above. As described above, the wear surfaces may be slightly raised portions  1370  in the connector receptacle housing. Raised portions  1370  may be formed of the same material as the other portions of connector housing  1310 , or they may be made of a different material. For example, they may be made of a more durable material. Raised portions or surfaces  1370  may be arranged such that they experience the friction imparted by connector inserts as they are inserted into receptacle housing  1310 . In this way, the surface near the front of the connector receptacle housing  1310  can experience less friction and attendant marring, and the look of the connector receptacle can be maintained over time. 
     In various embodiments of the present invention, it is desirable to provide connector receptacle housings for several connectors as a unit. For example, this can provide multiple connector receptacles that are aligned to each other. An example of how this may be done according to an embodiment of the present invention is shown in the following figures. 
       FIGS. 14A-14D  illustrate a number of connector receptacles according to an embodiment of the present invention at various times during a manufacturing process. In  FIG. 14A , a number of connector receptacle housings  1410  may be manufactured as a unit. This unit may be manufactured separately or as part of a device enclosure (not shown.)  FIG. 14B  illustrates an assembly including a number of tongues  1420  and contacts  1430 . In  FIG. 14C , tongue  1420  and contact assembly  1430  are covered with a frame  1440  having a number of fingers  1450 . In  FIG. 14D , this assembly is attached to the number of connector receptacle housings  1410 . 
       FIGS. 15A-15D  illustrate a connector receptacle according to an embodiment of the present invention at various times during a manufacturing process.  FIG. 15A  illustrates a connector receptacle according to an embodiment of the present invention. Connector receptacle  1500  may include housing  1510  and frame  1520 . Housing  1510  may further include tongue  1512 . Contacts  1530  may reside on tongue  1512 . Ground tabs  1522  and keys  1524  may also be included. Bracket  1526  may be attached to frame  1520  to provide a mechanical connection to a device enclosure. 
     Again, it is desirable in some circumstances to provide a connector receptacle having a reduced height. This may allow an electronic device to be thinner and otherwise save space. Accordingly, embodiments the present invention may provide connector receptacles having a housing where one or more sides have been omitted. In this specific example, a top portion of housing  1510  has been omitted. In this way, the omission of the housing portion may not be immediately noticeable to a user. This allows the height of connector receptacle  1500  to be reduced, while a pleasing aesthetic appearance is maintained. 
       FIG. 15B  illustrates a housing for a receptacle according to an embodiment of the present invention. In this figure, housing  1510  of connector receptacle  1500  may have an open area  1514  where a top of housing  1510  is absent or omitted. In other embodiments of the present invention, other portions of the housing, such as the bottom of the housing, may be omitted. 
     In  FIG. 15C , frame  1520  is attached to a back of housing  1510 . In  FIG. 15D , contacts  1512  are inserted into housing  1510 . In this embodiment of the present invention, contacts  1512  are surface mount contacts, though in other embodiments of the present invention, they may be through-hole contacts or other types of contacts. 
     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. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications to thereby enable others skilled in the art to best utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. Thus, it will be appreciated that the invention is intended to cover all modifications and equivalents within the scope of the following claims.
