BACKGROUND
The number and types of electronic devices available to consumers have increased tremendously the past few years, and this increase shows no signs of abating. Devices such as portable computing devices, tablet, desktop, and all-in-one computers, cell, smart, and media phones, storage devices, portable media players, navigation systems, monitors and other devices have become ubiquitous.
These devices often receive and provide power and data using various cable assemblies. These cable assemblies may include connector inserts, or plugs, on one or more ends of a cable. The connector inserts may plug into connector receptacles on electronic devices, thereby forming one or more conductive paths for signals and power.
The connector receptacles may be formed of housings that typically at least partially surround and provide mechanical support for contacts. These contacts may be arranged to mate with corresponding contacts on the connector inserts or plugs to form portions of electrical paths between devices. The connector receptacles may further include features to help to provide an initial resistance to the insertion of a connector insert. Features to provide retention to prevent inadvertent removal of a connector insert may also be included.
These connector receptacles may be attached or otherwise fixed to device enclosures that surround an electronic device. These enclosures may be highly stylized for both aesthetic and functional reasons. For example, portions of the device enclosures may be sloped, curved, or have other non-orthogonal shapes. These enclosures may also be thin or narrow.
The curvature or size of these enclosures may make it difficult to fit a connector receptacle to the enclosure. Moreover, a resulting connector receptacle may be difficult to assemble.
Also, these connector receptacles consume space inside the electronic device. This consumed space may mean that the device may become larger, some functionality may be lost, or that some tradeoff may have to be made. These losses may be mitigated by further contouring or reducing the size of the connector receptacle.
Thus, what is needed are connector receptacles that are contoured or reduced in size to fit in these stylized enclosures, avoid internal circuitry, provide a desired level of retention for a connector insert, and are relatively easy to assemble.
SUMMARY
Accordingly, embodiments of the present invention may provide connector receptacles having a contoured or reduced size form factor that allows use in stylized enclosures. These receptacles may also be contoured or reduced in size to avoid circuitry internal to the device enclosure. The contoured or reduced size form factor may also simplify the assembly of the connector receptacle. These connector receptacles may also include a latch piece to provide insertion resistance and retention features. This latch may provide both resistance to the insertion of a connector inserts and to prevent their inadvertent or accidental removal.
An illustrative embodiment of the present invention may provide a connector receptacle that may be contoured or reduced in size to fit in a curved device enclosure. To enable this fit, the connector receptacle may have an opening on a bottom of a housing. This opening may allow the insertion of contacts into place in the housing during assembly, thereby simplifying the assembly of the connector receptacle.
An illustrative embodiment of the present invention may provide a connector receptacle having a housing. The housing may have a front opening to accept a connector insert. The housing may have a bottom opening. The housing may further have first and second fastener openings, into which fasteners may be placed to fix the connector receptacle to a device enclosure. The housing may be plastic or other nonconductive material.
During assembly, contacts may be inserted into the housing through an opening in a bottom of the housing. These contacts may include a beam portion. The beam portion may be that part of a contact that is arranged to form an electrical connection with a corresponding contact on a connector insert when the connector insert is inserted into the connector receptacle. The contacts may further include a surface mount contact substantially in line with the beam portion, where the surface mount contacts are arranged to be soldered to a flexible circuit board, printed circuit board, or other appropriate substrate. The contacts may each further include a mechanical stabilizing portion substantially orthogonal to the beam portion. The mechanical stabilizing portion may be inserted into slots in the housing during assembly.
To protect these contacts after assembly, a piece of tape or other cover may be placed over at least a portion of the opening in the bottom of the housing.
The connector receptacle may further include a latch or ground piece. The latch or ground piece may include contacts at each end, which are joined by a back piece. The contacts may be placed in the housing through a back opening such that ground contacts on sides of a connector insert are in electrical contact with the contacts.
The contacts on the latch or ground piece may further provide retention features for the receptacle. The retention features may provide a resistance to the insertion of a connector insert into the connector receptacle. The retention features may further provide a holding force to help keep the connector insert in place and reduce or prevent the inadvertent removal of the connector insert. However, during assembly, the contacts on the ground piece may be spread apart. This may also occur during insertion of a connector inserts. This spreading may reduce the retention force provided by the ground piece contacts, which may also lead to a reduced reliability for the ground contacts. To reduce this loss in retention the ground piece may be annealed. To provide a further reduction in loss, the ground piece may further be hardened, though the annealing step may be omitted. In other embodiments of the present invention, one or more annealing, hardening, and other processing steps may be used.
The connector receptacle may further include a bracket. The bracket may include a first fastener opening and a second fastener opening. The first fastener opening may align with the first fastener opening in the housing, while the second fastener opening may align with the second fastener opening in the housing. Again, fasteners may be placed in the fastener openings in order to attach or fix the connector receptacle to a device enclosure. The bracket may include tabs arranged to fit in cutouts on the housing to secure the bracket to the housing. Either or both the ground piece or bracket may include tabs, which may be soldered to ground paths on a flexible circuit board, printed circuit board, or other appropriate substrate, though one or more of these tabs may be included on the ground piece or other portion of the connector receptacle. The contacts, latch or ground piece, ground contacts, shield, and bracket may be formed of plastic, metal, ceramic, or other materials. For example, they may be formed of stainless steel, such as stainless steel (304), stainless steel (301), or low carbon steel (1010), titanium, brass, gold-plated brass, or other appropriate material.
Another illustrative embodiment of the present invention provides a method of assembling a connector receptacle. This method may include receiving a housing. The housing may be contoured to fit in a stylized enclosure. The housing may have a front opening, a bottom opening, and a back opening. Contacts may be placed into the housing through the bottom opening. The contacts may include beam, surface mount, and mechanical stabilizing portions. The mechanical stabilizing portions may be inserted into slots in the housing. A first piece of tape may be placed over the bottom opening in the housing. In other embodiments of the present invention, a shield portion, or plastic portion, may be used in place of the tape.
A latch or ground piece including ground contacts may be inserted into the back opening of the housing. A tab on the housing may fit in a notch in the ground piece to hold the ground piece in place. A second piece of tape, which may be two-sided, may be placed over a back portion of the ground piece. A bracket may be fixed to the housing and held in place by the second piece of tape. The bracket may include tabs that fit into cutouts in the housing to hold the bracket in place. Fasteners may be placed through fastener openings in the housing and bracket to attach the connector receptacle to a device enclosure. These enclosures may be enclosures for portable computing devices, tablet, desktop, and all-in-one computers, cell, smart, and media phones, storage devices, portable media players, navigation systems, monitors and other devices.
Other embodiments of the present invention may provide connector receptacles having additional structures for waterproofing or to increase water resistance. In various embodiments of the present invention, connector receptacles may include seals or plugs may be used to prevent or limit the ingress of water or other fluids or liquids into an electronic device.
Another illustrative embodiment of the present invention may provide a connector receptacle. This connector receptacle may include a plurality of contacts, each contact including a beam portion and a mechanical stabilizing portion substantially orthogonal to the beam portion. The connector receptacle may further include a housing having a front opening and a top opening allowing access to a number of slots in the housing, where the mechanical stabilizing portion of each of the plurality of contacts is inserted in a slot. A cap may at least substantially cover the top opening in the housing. A gasket may be placed between the cap and the housing. The receptacle may also include a latch piece including a left arm and a right arm, the left arm and the right arm joined by a back piece, the left arm and the right arm terminating in side contacts located on sides of the front opening of the housing. The left arm and the right arm may be inserted in right and left openings in a rear of the housing. A seal, such as a piece of Mylar or Mylar tape, may cover the right and left openings in a rear of the housing. Instead of a seal, other embodiments of the present invention may employ plugs to seal right and left openings in a rear of the housing.
In various embodiments of the present invention, the components of the connector receptacles may be formed in various ways of various materials. For example, contacts and other conductive portions may be formed by stamping, metal-injection molding, machining, micro-machining, 3-D printing, or other manufacturing process. The conductive portions may be formed of stainless steel, steel, copper, copper titanium, phosphor bronze, or other material or combination of materials. They may be plated or coated with nickel, gold, or other material. The nonconductive portions, such as the receptacle housings, seals, gaskets, and other portions, may be formed using injection or other molding, 3-D printing, machining, or other manufacturing process. The nonconductive portions may be formed of silicon or silicone, Mylar, Mylar tape, rubber, hard rubber, plastic, nylon, elastomers, liquid-crystal polymers (LCPs), ceramics, or other nonconductive material or combination of materials.
Embodiments of the present invention may provide connector receptacles that may be located in, and may connect to, various types of devices, such as portable computing devices, tablet computers, desktop computers, laptops, all-in-one computers, wearable computing devices, cell phones, smart phones, media phones, storage devices, portable media players, navigation systems, monitors, power supplies, adapters, remote control devices, chargers, and other devices. These connector receptacles may provide pathways for signals that are compliant with various standards such as Universal Serial Bus (USB), High-Definition Multimedia Interface® (HDMI), Digital Visual Interface (DVI), Ethernet, DisplayPort, ThunderboltTM, LightningTM, Joint Test Action Group (JTAG), test-access-port (TAP), Directed Automated Random Testing (DART), universal asynchronous receiver/transmitters (UARTs), clock signals, power signals, and other types of standard, non-standard, and proprietary interfaces and combinations thereof that have been developed, are being developed, or will be developed in the future.

Specifically, mechanical stabilization portions 917 may be inserted into slots in housing 920. Once these contacts are in place, tape or cover 960 may be used to cover this opening and protect contacts 910 and 915.
Again, latch or ground piece 930 (or 130 or the other ground pieces included below) may have contacts 932 spread apart during assembly, and again during insertion of connector inserts. This may permanently work the ground contacts 932 apart, reducing ground contact reliability and reducing retention force. The latch or ground piece 930 is shown in more detail in the following figure.
FIG. 11 illustrates front and rear oblique views of latch or ground piece 930 according to an embodiment of the present invention. Again, the distance W1 between contacts 932 of latch or ground piece 930 may increase due to stresses from assembly and insertion of connector inserts. This increase in W1 may lead to reduced retention force and reduced ground contact reliability.
To mitigate, reduce, or eliminate this increase, latch or ground piece 930 (and 130) may undergo various processing steps. For example, latch or ground piece 930 may be annealed. After annealing, latch or ground piece 930 may further be hardened.
