Description:

     BACKGROUND 
     This relates generally to electronic devices and, more particularly, to connectors such as radio-frequency connectors for use in electronic devices. 
     Electronic devices often contain connectors. For example, electronic equipment may contain coaxial cable connectors that mate with coaxial cables. Coaxial cables are often used to convey radio-frequency signals such as video signals. 
     Components in electronic devices such as radio-frequency circuits may use electromagnetic interference (EMI) shielding structures. Electromagnetic interference shielding structures may help prevent radio-frequency signals that are generated by one component from disrupting the operation of another component that is sensitive to radio-frequency interference. Electromagnetic shielding structures may be formed from metal shielding cans soldered to printed circuit boards. 
     It can be challenging to mount connectors in electronic devices. Connectors that are not mounted to printed circuit boards are often cumbersome, because they may need to be secured to device housings using fasteners such as nuts and may require that solder connections be formed following attachment of the connector to the housing. Space is often at a premium in electronic devices, so mounting arrangements in which shielding structures and connectors compete for space on a printed circuit or in which connectors are bulky may not be acceptable. 
     It would therefore be desirable to be able to provide improved connectors for use in electronic devices. 
     SUMMARY 
     An electronic device may have electrical components mounted on a printed circuit board. The printed circuit board may be mounted within a housing. A connector may be mounted to an edge of the printed circuit board using solder, so that a portion of the connector protrudes through an opening in the housing. 
     The protruding portion of the connector may be formed from a threaded barrel mounted in a connector body member. The threaded barrel may have a first threaded portion that is configured to mate with a coaxial cable connector. The threaded barrel may also have a second threaded portion that screws into a threaded opening in the connector body. A threadless portion of the threaded barrel between the first and second threaded portions may be aligned with the housing. 
     The connector body member may be covered with the metal shell. A portion of the metal shell may form an electromagnetic interference shielding cavity in which the electrical components are housed. By covering the electrical components with the electromagnetic interference shielding cavity formed from the metal shell, the metal shell may serve both as a portion of the connector and as an electromagnetic interference shielding structure for the electrical components. 
     The metal shell and the connector body may have aligned openings configured to receive a threaded set screw. The threaded barrel may have a flat area aligned with thread initiation and termination points. When the set screw bears against the flat area, the threaded barrel may be rotationally aligned so that the thread initiation and termination points are located out of view on the lower side of the threaded barrel. 
     Further features, their nature and various advantages will be more apparent from the accompanying drawings and the following detailed description of the preferred embodiments.

     DETAILED DESCRIPTION 
     An electronic device may be provided with electronic components such as integrated circuits. These components may be mounted on a printed circuit board. Connectors may also be mounted on the printed circuit board. For example, a coaxial cable connector or other connector for mating with an external cable may be mounted on an edge of a printed circuit board. The connector may include integral electromagnetic interference shielding structures for shielding some of the electronic components on the printed circuit board. As an example, an amplifier integrated circuit that is used in amplifying signals passing through the connector may be shielded using the integral electromagnetic interference shielding structures. The connector may also have features to minimize size and improve device aesthetics. 
     An illustrative electronic device of the type that may be provided with a printed circuit board connector is shown in  FIG. 1 . Electronic device  10  of  FIG. 1  has openings  14  in housing  12 . Openings  14  form connector ports for connectors such as Ethernet plugs, Universal Serial Bus connectors, power connectors, audio jacks, connectors for coaxial cables for television signals and other signals, and other connectors. Housing  12 , which may sometimes be referred to as an enclosure or case, may be formed of plastic, glass, ceramics, fiber composites, metal (e.g., stainless steel, aluminum, etc.), other suitable materials, or a combination of any two or more of these materials. Housing  12  may be formed using a unibody configuration in which some or all of housing  12  is machined or molded as a single structure or can be formed using multiple structures (e.g., an internal frame structure, one or more structures that form exterior housing surfaces, etc.). 
     Electronic device  10  of  FIG. 1  may be a set-top box, a wireless access point, a router, a storage device, a device for providing still and moving images to an attached display such as a television or computer monitor, a cellular telephone, a handheld portable device such as a media player, a somewhat smaller portable device such as a wrist-watch device, a pendant device, other wearable or miniature device, gaming equipment, tablet computer, notebook computer, desktop computers, television, computer monitor, a computer integrated into a computer display, a hybrid device that includes the functionality of two or more devices such as these, or other electronic equipment. The use of a set-top box form factor of the type shown in the example of  FIG. 1  in implementing device  10  is merely illustrative. 
     Device  10  may include internal structures such as printed circuits. Electrical components may be mounted on the printed circuits and may be electrically connected through conductive paths in the printed circuits and in external cables. Printed circuits in device  10  may include rigid printed circuit boards (e.g., printed circuits formed from fiberglass-filled epoxy or other rigid substrate material) and/or flexible printed circuits (e.g., printed circuit substrates formed from flexible polymer layers such as sheets of polyimide). 
     Components that may be mounted on the printed circuits include power supply components, inductors, capacitors, resistors, integrated circuits such as amplifiers and other integrated circuits, switches, connectors, sensors, wireless circuits, and other electrical components. Some of these components and the printed circuits on which the components are mounted may be mounted within the interior of a shielding enclosure that is formed as part of a connector. The connector may be, for example, be a printed circuit board connector that is mounted on the edge of one of the printed circuit boards in device  10 . With one suitable configuration, which is sometimes described herein as an example, the connector may be a coaxial cable connector such as connector  16  of  FIG. 1   
     Coaxial cable connector  16  may be a female coaxial cable F connector or other connector suitable for coupling to external cables such as coaxial cable  26 . Cable  26  may be terminated in a male coaxial cable F connector  22  or other suitable male cable connector. Connector  22  may have a threaded grounded body  24  that surrounds central positive signal pin  20 . Signal pin  20  in male connector  22  may be a protruding center conductor associated with coaxial cable  26 . Threaded male connector body  24  may screw onto mating threads in a threaded barrel in connector  16  (see, e.g., the protruding cylindrical portion of connector  16  that protrudes through the circular opening  14  in housing  12  in the  FIG. 1  example). When male connector  22  is installed on female connector  16  of device  10  in this way, male connector pin  20  will be received within center conductor  18  of female connector  16 . 
     A top view of an interior portion of electronic device  10  is shown in  FIG. 2 . As shown in  FIG. 2 , printed circuit board  28  may be mounted in the cavity formed in the interior of housing  12 . Electrical components  30  may be mounted on printed circuit board  28 . Electrical components  30  may include integrated circuits, discrete components such as resistors, capacitors, and inductors, switches, application-specific integrated circuits, processor circuits, storage, video processing circuitry, wireless transceiver circuitry, and other circuitry. Components  30  may be interconnected with each other and connectors such as connector  16  using wires, metal traces in printed circuit board  28 , flexible printed circuit cables, coaxial cables, and other signal path structures. For example, a microstrip transmission line or other transmission line formed from metal traces on printed circuit board  28  such as transmission line path  32  may be used to route signals between the circuitry of components  30  and connector  16 . 
     Connector  16  may have a portion such as portion  34  that protrudes from housing  12 . Portion  34  may include the tip of a threaded barrel. Connector  16  may also have a portion such as portion  36  (sometimes referred to as a connector body assembly) that is mounted on printed circuit  28  and that is housed within the interior of housing  12 . 
       FIG. 3  is a perspective view of an edge portion of printed circuit board  28  showing how connector  16  may be mounted to printed circuit board  28 . Printed circuit board  28  may be formed from a rigid printed circuit board substrate material such as fiberglass-filled epoxy. Metal traces in printed circuit board  28  such as metal traces  32 A and  32 B may be used to form transmission lines and other signal paths. In transmission line path  32 , for example, metal trace  32 A may form a positive transmission line conductor and metal trace  32 B may form a ground transmission line conductor (as an example). Metal trace  32 A and other positive signal conductors associated with connector  16  may be coupled to positive connector center contact  18 . Metal trace  32 B and other ground signal conductors associated with connector  16  may be coupled to metal threads  44  in portion  34  of connector  16 . 
     Body assembly (body structures)  36  of connector  16  may include a body member such as body  40  (e.g., a cast or machined member formed from stainless steel, brass, or other metal) covered with a stamped metal shell such as stainless steel shell  38  or a metal shell formed from other metals. Metal trace  32 B may be shorted to metal shell  38  in connector body assembly  36  using solder pad portion  32 B′ of metal trace  32 B and solder  42 . The solder joint formed from solder  42  may attach connector  36  to printed circuit board  28 . Attachment mechanisms such as screws or other fasteners, welds, mounting brackets, adhesive, and other mounting structures may be used, if desired. By attaching connector  16  to board  28  prior to insertion of printed circuit board  28  into housing  12 , potentially cumbersome operations associated with wiring a separate connector to traces  32 A and  32 B after board installation can be avoided. 
       FIG. 4  is a top interior view of a corner portion of electronic device  10  showing how portion  34  of connector  16  may extend through opening  14  in the wall of housing  12  to expose threads  44 . Threads  44  may lie within protruding threaded portion  70 . Threadless portion  72  of connector  16  may be aligned with opening  14  in housing  12  (i.e., threadless portion  72  overlaps the wall in housing  12 ). Conductive paths such as ground conductive path  32 B″ may couple threads  44  of connector  16  to metal shell  38  and other grounded elements. Conductive paths such as positive signal path  32 A″ may be coupled to center conductor terminal  18  (i.e., the positive terminal of connector  16 ). 
     The signals on positive line  32 A″ and ground line  32 B″ may be routed to respective positive signal path  32 A and ground path  32 B via one or more electrical components  30 ′. Electrical components  30 ′ may be mounted on printed circuit board  28  under a portion of metal shell  38 . Electrical components  30 ′ may include amplifier circuitry, filter circuitry, and other circuitry for enhancing signal strength and quality. Electrical components  30 ′ may, for example, include one or more integrated circuits (e.g., amplifier integrated circuits) and discrete components such as capacitors, inductors, and resistors. 
     The circuitry formed from electrical components  30 ′ may produce electromagnetic interference signals that have the potential to interfere with other components  30  in device  10  such as other components  30  on printed circuit board  28 . There is also a potential for electromagnetic signal interference that is generated by components  30  to interfere with the operation of electrical components  30 ′. By mounting components  30 ′ under metal connector shell  38 , metal connector shell  38  may serve as an electromagnetic interference shielding structure that helps shield components  30 ′ from interference from components  30  and that helps shield components  30  from interference from components  30 ′. 
       FIG. 5  is an exploded perspective view of connector  16 . As shown in  FIG. 5 , connector  16  may include threaded barrel  68 . Barrel  68  may be formed from metals such as brass or stainless steel (as examples). Barrel  68  may be provided with threads such as threads  44  to mate with threaded connector member  24  in cable connector  22  ( FIG. 1 ). For example, threads  44  may be configured to form a female coaxial cable F connector that mates with a corresponding male coaxial cable F connector. Barrel  68  may also be provided with threads  78  that mate with a threaded cylindrical opening in connector body  40 . Threaded barrel  68  may have portions with different outer diameters. Threaded portion  70  may, for example, have a larger diameter than threaded portion  78 . 
     A portion such as threadless portion  72  may be formed between threaded portions  70  and  74 , if desired. When mounted in device  10 , portion  72  may be aligned with the wall of housing  12 . By ensuring that portion  72  is bare of threads, tight tolerances (small gaps) may be established between barrel  68  and the opening (opening  14 ) in housing  12  through which barrel  68  passes. 
     Threaded barrel  68  may have an opening such as opening  76  into which center contact components  56  are mounted. Components  56  may include metal center contact pin  58 , hollow metal rod  60 , springs  62  and  64 , and hollow dielectric cylinder (sheath)  66 . When assembled, springs  62  and  64  may be inserted into opposing ends of hollow metal rod  60 . Spring  62  receives one end of metal pin  58 . The opposing end of metal pin  58  may form positive signal path  32 A″ of  FIG. 4 . When connector  22  is screwed onto threads  44  of connector  16 , center conductor  20  of connector  22  will be received within spring  64 . Dielectric cylinder  66  shields the center conductor contact of connector  16  from the ground contact formed from barrel  68 . 
     When assembled to form a completed connector, components  56  and threaded barrel  68  are mounted in connector body  40 . Body  40  may be formed from a brass member, a stainless steel member, or other metal structure (as examples). Threaded barrel  68  may be held in place within body  40  using set screw  54 . 
     Metal shell  38  may have a portion such as portion  50  that is configured to receive metal body  40 . Metal shell  38  may also have portion  52  that serves as an electromagnetic interference shield that overlaps and shields electrical components  30 ′ on printed circuit board  28 . In region  52 , the lower edge of shell  38  may have a straight surface to facilitate formation of solder joints such as solder joint  42  of  FIG. 3 . In the illustrative example of  FIG. 5 , shell  38  has optional prong  48 . Prong  48  may be received within a mating hole in printed circuit board  28 . In configurations in which prongs such as prong  48  are provided on shell  38 , the prongs may help secure connector  16  to printed circuit board  28 . If desired, the lower edge of shell  38  in region  52  may be provided with protrusions  46  (e.g., castellation features) as shown in the example of  FIG. 5  to help reduce solder wicking. 
       FIG. 6  is a partially exploded top perspective view of connector  16 . As shown in  FIG. 6 , threads  78  of reduced diameter portion  74  of threaded barrel  68  may be received by corresponding threaded cylindrical opening  80  in body  40  of connector body assembly  36 . Set screw  54  may be used to secure threaded barrel  68  after threaded barrel  68  has been screwed into opening  80 . Because the diameter of internal threaded portion  74  of connector  16  is smaller than the diameter of external threaded portion  70  of connector  16 , the volume of body member  40  that is required to form threaded cylindrical opening  80  in body  40  can be reduced, thereby helping to ensure that connector  16  is not overly bulky. The diameter of external threaded portion  70  may be configured to mate with ground connector portion  24  of connector  22 . For example, if connector  22  is a male cable F connector, threaded portion  70  may be sized to form a mating female F connector. 
       FIG. 7  is a top perspective view of connector  16  of  FIG. 6  following assembly of connector  16  by screwing threaded barrel  68  into opening  80  in the front face of body  40  and after screwing set screw  54  into a corresponding threaded opening in the lower surface of body  40 . 
       FIG. 8  is a partially exploded bottom perspective view of connector  16  showing how opening  82  of connector body assembly  36  may be formed by aligned circular openings in shell  38  and connector body  40 . Set screw  54  may have threads that are received by corresponding threads within body assembly opening  82  (i.e., threads formed on the inner walls of the cylindrical opening in body  40 ). Threaded barrel  68  may have a flattened portion such as flat area  84  in reduced-diameter threaded region  74 . Set screw  54  may bear against flat portion  84  of threaded barrel  68  when barrel  68  is screwed into connector body assembly  36 . This helps ensure that barrel  68  is assembled with a desired rotational orientation with respect to rotational axis  86  of barrel  68 . 
       FIG. 9  is a bottom perspective view of connector  16  of  FIG. 8  following assembly of connector  16 . In the configuration of  FIG. 9 , threaded barrel  68  has been screwed into threaded opening  80  in connector body assembly  36  ( FIG. 6 ) and set screw  54  has been screwed into set screw opening  82  in connector body assembly  36  ( FIG. 8 ). As shown in  FIG. 9 , stamped metal shell  38  contains portions such as shielding portion  52  with sidewalls  93  and upper wall  95  that define an internal electromagnetic interference shielding cavity (cavity  91 ) for receiving and shielding components  30 ′ on printed circuit board  28 . Cavity  91  may have a rectangular box shape (e.g., in arrangements of the type shown in  FIG. 9  in which shell  38  forms an upside-down open box) or may have other shapes (e.g., shapes with curved edges, shapes with more than one cavity height above printed circuit board  28 , etc.). The configuration of  FIG. 9  is merely illustrative. 
     As shown in  FIG. 10 , external threaded portion  70  of threaded barrel  68  may have threads  44 . Threads  44  may start and end at locations such as locations  88  and  90 . Locations  88  and  90  may sometimes be referred to as thread initiation and termination discontinuities, thread discontinuities, thread endpoints, or thread initiation and termination points. For example, location  88  may be referred to as a thread initiation discontinuity (i.e., a point at which threads  44  start along the length of barrel  69  parallel to rotational axis) and location  90  may be referred to as a thread termination discontinuity (i.e., a point at which threads  44  finish). 
     The presence of thread initiation and termination points in threads  44  may be unsightly to a user of device  10 . As shown in  FIG. 11 , thread initiation and termination points  88  and  90  may be hidden from view by locating thread initiation and termination points  88  and  90  on the underside of threaded barrel  68  in alignment with flat area  84 . When set screw  54  bears against flat area  84 , the rotational orientation of threaded barrel  68  about rotational axis will be established so that thread initiation and termination points  88  and  90  will be located on the underside of barrel  68  and connector  16 , hidden from view. 
     The foregoing is merely illustrative and various modifications can be made by those skilled in the art without departing from the scope and spirit of the described embodiments. The foregoing embodiments may be implemented individually or in any combination.
