Power and data may be provided from one electronic device to another over cables that may include one or more wire conductors, fiber optic cables, or other conductors. Connector inserts may be located at each end of these cables and may be inserted into connector receptacles in the communicating or power transferring electronic devices.
Users may insert these connector inserts into connector receptacles many times. Occasionally, such an insertion may damage a connector receptacle. Such damage to the connector receptacle may reduce the functionality of the electronic device housing the connector receptacle. In a worst-case situation, such damage may render the electronic device inoperable. Accordingly, it may be desirable that these connector receptacles may be reliable and able to withstand a large number of insertions by connector inserts.
Various electronic devices may generate a large demand by consumers. Yield problems may impair a manufacturer's ability to deliver the electronic devices to fill this demand. Accordingly, it may be desirable to provide connector receptacles that may be readily manufactured.
Also, contacts in a connector receptacle may convey high-speed signals along with power supplies and other signals. Connector structure can contribute signal noise, distortion and losses due to the fast rising/falling edges of the high speed signals. At high bit rates, these effects can degrade the electrical signal to the point when errors occur and system or device fails. Also, high-speed signals may generate electromagnetic interference (EMI) and radiation, which may couple to other devices and circuits in or associated with the electronic device. Accordingly, it may be desirable to provide connector receptacles that are less susceptible to EMI and have a high signal quality.
Thus, what is needed are connector receptacles that may be reliable, may readily manufactured, and may provide high signal quality for high speed signals with minimized signal noise, distortion losses, radiation, and interference.
Accordingly, embodiments of the present invention may provide connector receptacles that may be reliable, may readily manufactured, and may provide high signal quality for high speed signals with minimized signal noise, distortion losses, radiation, and interference.
An illustrative embodiment of the present invention may provide a reliable connector receptacle that is less susceptible to damage during an insertion of a connector insert. In some connector receptacles, a contact may lift or separate from a supporting tongue. The contact may then be bent when a front edge of the contact is engaged by a connector insert when the connector insert is inserted into the connector receptacle. Accordingly, embodiments of the present invention may provide connector receptacles that may include a number of contacts having contacting portions to mate with corresponding contacts in a connector insert, where the contacting portions may be formed to be bent or angled at one or more positions along their lengths. For example, a first bend may angle the contacting portion away from a supporting tongue and a second bend may angle the contacting portion towards the tongue. The second bend may be between the first bend and a front of the tongue and connector insert. This double-bend arrangement may increase an angle of the contacting portion relative to the tongue near a front of the tongue. This increased angle may help to prevent the separation of the contacting portion of a contact from a supporting tongue, thereby improving reliability of the connector receptacle. More specifically, the increased angle may provide a pre-bias force on the contacting portion pushing against the tongue. This pre-bias force may help to prevent the contacting portion from separating from the tongue, which may prevent the contacting portion from being bent when a connector insert is inserted into the connector receptacle.
Another illustrative embodiment of the present invention may provide a connector receptacle that is readily manufactured. A connector receptacle may include a housing having a tongue, where the tongue may be formed separately from the housing or as part of the housing. A rear of the tongue may include a number of openings, each for a corresponding one of a number of contacts. The rear openings may have tapered lead-ins to prevent contacting portions of the contacts from stubbing against the rear of the tongue when the contacts are inserted onto the tongue.
Another illustrative embodiment of the present invention may provide a connector receptacle that may provide high signal quality for high speed signals with minimized signal noise, distortion, losses, radiation, and interference. For example, through-hole contact portions of signal contacts may be arranged in lines that are separated from each other by intervening through-hole contact portions of ground contacts. A housing for the connector receptacle may be shielded with a top and a bottom shield. Also, the through-hole contact portions for its contacts may be arranged in an array, where the array has rows of tabs on each for four sides, the tabs connected to the top and bottom shields and arranged to fit in openings in a printed circuit board or other appropriate substrate to form ground connections.
In these and other embodiments of the present invention, power supply and signal contacts may include through-hole contact portions. These through-hole contact portions may fit in openings in a printed circuit board or other appropriate substrate to form electrical connections with traces in the printed circuit board or other appropriate substrate. These through-hole contact portions may also provide mechanical stability for the combined connector receptacle. In other embodiments of the present invention, some or all of the contacts may terminate in surface-mount contacting portions.
While embodiments of the present invention may be useful in HDMI connector receptacles, these and other embodiments of the present invention may be used in other types of connector inserts and connector receptacles for different interfaces.
In various embodiments of the present invention, contacts, shields, EMI or ground contacts, beams, cross-beams, and other conductive portions of a connector receptacle or connector insert 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 housings, rear housings, tongues, and other structures 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, rubber, hard rubber, plastic, nylon, liquid-crystal polymers (LCPs), ceramics, or other nonconductive material or combination of materials. The printed circuit boards used may be formed of FR-4 or other material. Printed circuit boards may be replaced by other substrates, such as flexible circuit boards, in many embodiments of the present invention.
Embodiments of the present invention may provide connector receptacles and connector inserts 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, video delivery systems, adapters, remote control devices, chargers, and other devices. These connector receptacles and connector inserts may provide pathways for signals that are compliant with various standards such as one of the Universal Serial Bus (USB) standards including USB Type-C, High-Definition Multimedia Interface® (HDMI), Digital Visual Interface (DVI), Ethernet, DisplayPort, Thunderbolt™, Lightning™, 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. Other embodiments of the present invention may provide combined connector receptacles that may be used to provide a reduced set of functions for one or more of these standards. In various embodiments of the present invention, these interconnect paths provided by these connector inserts and connector receptacles may be used to convey power, ground, signals, test points, and other voltage, current, data, or other information.
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.
This example illustrates a monitor 130 that may be driven by one of two sources, specifically computer 110 or set-top box 140. Computer 110 may provide video data over cable 120 to monitor 130. Video data may be displayed on the video screen 132 of monitor 130. Computer 110 may similarly include a screen 112. Set-top box 140 may provide video data over cable 150 to monitor 130. Again, this video data may be displayed on screen 132 of monitor 130. In other embodiments the present invention, other types of devices may be included, and other types of data may be shared or transferred among the devices. For example, monitor 130 may be a monitor, an all-in-one computer, tablet computer, or other device having screen 132. In these and other embodiments of the present invention, power may be shared among computer 110, monitor 130, and set-top box 140 over cables 120 and 150.
Cables 120 and 150 may be various types of cables. For instance, they may be HDMI, Thunderbolt, DisplayPort, USB Type-C, or other types of cables. These cables may include connector inserts (not shown) that plug into connector receptacles (not shown) on the computer 110, monitor 130, and set-top box 140.
These connector receptacles may become damaged when connector inserts attached to cables 120 and 150 are inserted into them. For example, an HDMI connector receptacle may include a tongue supporting contacting portions of a number of contacts. One or more of these contacting portions may lift or separate from the supporting tongue. The separated contacting portion may engage a connector insert as it is inserted into the connector receptacle. This may cause the contacting portion to become bent or damaged. This damage may render the device at least partially inoperable. Accordingly, embodiments of the present invention may provide reliable connector receptacles. Examples are shown in the following figures.
Connector receptacle 200 may include a front portion 202 and a rear portion 204. Rear portion 204 may include tabs 252 and through-hole contact portions 234 for mating with a printed circuit board. Front portion 202 of connector receptacle 200 may reside at an edge or in a U-shaped notch in an edge of a printed circuit board. Again, side tab 254 may reside on a surface of a printed circuit board for alignment and mechanical purposes. Side tab 254 may further be soldered to a pad or contact on a surface of a printed circuit board (not shown) for grounding and mechanical support.
While embodiments of the present invention are well-suited to connector receptacles, tongue 220 may be a tongue of a connector insert. Where tongue 220 is a tongue of a connector insert, remaining portions of housing 210 may be omitted.
Bottom shield 350 may be fit over a bottom portion of housing 210. Top shield 250 may be fit over bottom shield 350 and housing 210. Openings 256 on top shield 250 may engage tabs 352 on bottom shield 350 to secure top shield 250 and bottom shield 350 together. Top shield 250 and bottom shield 350 may also be spot or laser welded to each other and to beams 242 and cross bars 246. Contacts 230 may include through-hole contact portions 234 and may be at least partially housed in first rear housing 310. Contacts 231 may similarly include through-hole contact portions 235 and may be at least partially housed in second rear housing 311. Contacts 230 and 231 may be collectively referred to as contacts 230, through-hole contact portions 234 and 235 may be collectively referred to as through-hole contact portions 234, and rear housing portions 310 and 311 may be collectively referred to as housings 310, for simplicity.
Connector receptacle 200 may be manufactured in very large numbers. Accordingly, embodiments of the present invention may provide connector receptacles that may be readily manufactured. Examples are shown in the following figures.

Again, embodiments of the present invention may provide connector receptacles that are reliable and less susceptible to damage. For example, they may be less susceptible to damage that may occur during an insertion of a connector insert into the connector receptacle. One embodiment of the present invention may provide a plurality of contacts where the contacts are less prone to separate from a tongue or other housing portion. Since they are less likely to separate from the tongue or other housing portion, they may be less susceptible to being bent by a connector insert when the connector insert is inserted into the connector receptacle. Examples of such contacts are shown in the following figures.
In various embodiments of the present invention, the bends at locations 1110 and 1120 may have different magnitudes. For example, the first bend at location 1110 may form an angle 1130 of approximately 1, 2, 3, 4, or more than four degrees. The second bend at location 1120 may form angle 1140 that is approximately twice angle 1130. For example, angle 1140 may be approximately 2, 4, 6, 8 or more than 8 degrees. This combination of bends may increase an angle between contacting portion 232 and a tongue or other housing portion of a connector. This is shown in more detail in
Again, embodiments of the present invention may provide connector receptacles that are readily manufactured. In one embodiment of the present invention, openings and a rear of tongues 220 (shown in
Again, it may be desirable that contacts 230 are not damaged when a connector insert is inserted into this connector receptacle. Accordingly, contacts 230 may include a number of bends such that tip 237 of contact 230 is less likely to separate from tongue 220. In this particular embodiment, contacts 230 may include bends at locations 1110 and 1120. The bend at 1110 may be in a downward angle such that contacting portion 232 is further away from tongue 220 at location 1120. The second bend at location 1120 may angle contact 230 such that contact tip 237 may be adjacent to tongue 220. This may provide a pre-bias on contact 230 such that it tends to stay in contact with tongue 220. Contacting portions (not shown) on a top side of tongue 220 may follow a mirror image of contacting portions 232.
It may also be desirable to shield signals on contacts 230 from outside sources. Accordingly, contacting portions 232 may be shielded on a top and sides by top shield 250 and on a bottom and sides by bottom shield 350. Through-hole contact portions 234 may be shielded by tabs 252. Tabs 252 may be formed as part of, or connected to, top shield 250 or bottom shield 350. Tabs 252 may be indirectly connected to a shield through cross beam 242, or tabs 252 may be arranged in lines on each side of an array of through-hole contact portions 234, thereby shielding the array of through-hole contact portions 234.
In other embodiments of the present invention, tongue 220 may be a tongue of a connector insert. For example, contacts 230 may include the same or similar bends as contacts for a connector insert. Also, in other embodiments of the present invention, contacts 230 may be located elsewhere in a connector receptacle or a connector insert. For example, contacts 230 may be located along a top or bottom side of a connector receptacle or connector insert opening. An example is shown in the following figure.
Modern screens, such as screen 132 in
In these and other embodiments of the present invention, power supply and signal contacts may include through-hole contact portions. These through-hole contact portions may fit in openings in a printed circuit board or other appropriate substrate to form electrical connections with traces in the printed circuit board or other appropriate substrate. These through-hole contact portions may also provide mechanical stability for the combined connector receptacle. In other embodiments of the present invention, some or all of the contacts may terminate in surface-mount contacting portions.
While embodiments of the present invention may be useful in HDMI connector receptacles, these and other embodiments of the present invention may be used in other types of connector inserts and connector receptacles for different interfaces.
In various embodiments of the present invention, contacts, shields, EMI or ground contacts, beams, cross-beams, and other conductive portions of a connector receptacle or connector insert 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 housings, rear housings, tongues, and other structures 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, rubber, hard rubber, plastic, nylon, liquid-crystal polymers (LCPs), ceramics, or other nonconductive material or combination of materials.
