Abstract

Receptacle connectors and male plug connectors having a reduced size in at least one direction can be provided. One example reduces height by not including a center contact tab or tongue, but instead places contacts on an insulator that is adjacent to a bottom portion of the receptacle. Another example may reduce width by reducing contact pitch, and may use a particular shape of contact to achieve god signal quality. Receptacle connectors and male plug connectors can also provide support for one or more new high-speed communication standards, such as USB 3.0 and DisplayPort. Methods can provide one or more standardized connector components to speed connector design and manufacture of new electronic devices such as media players, thus reducing their time to market.

Claims

1. A connector comprising:

a housing designed to accommodate a plurality of contacts, the housing including a plurality of contact locations for locating the plurality of contacts,

wherein the plurality of contact locations include a first set of contact locations designated for USB 3.0 signals and a second set of contact locations designated for DisplayPort signals.

2. The connector of claim 1, wherein the plurality of contact locations are spaced apart in a row.

3. The connector of claim 2, wherein the first set of contact locations designated for USB 3.0 signals are located along the row before the second set of contact locations designated for DisplayPort signals.

4. The connector of claim 1, further comprising signal contacts disposed at the first and second set of contact locations.

5. The connector of claim 4, wherein the plurality of contact locations are spaced apart in a row, and wherein a contact for carrying ground is disposed between at least some of the signal contacts for carrying USB 3.0 signals and all of the signal contacts for carrying DisplayPort signals.

6. The connector of claim 5, wherein a level of crosstalk between data signals on the signal contacts is less than 3%.

7. The connector of claim 5, wherein an impedance of the signal contacts for carrying USB 3.0 signals is 90 Ohms plus or minus 10%, and wherein an impedance of the signal contacts for carrying DisplayPort signals is 100 Ohms plus or minus 10%.

8. The connector of claim 4, wherein the signal contacts for carrying USB 3.0 signals for transmitting are located next to each other on a substrate, and wherein the signal contacts for carrying USB 3.0 signals for receiving are located next to each other on a substrate.

9. The connector of claim 1, wherein the connector is a male plug connector for connecting to a corresponding female receptacle connector.

10. The connector of claim 1, wherein the connector is a female receptacle connector for connecting to a corresponding male plug connector.

11. An electronic device comprising the female receptacle connector of claim 10.

12. A connector comprising:

an insulator surface designed to accommodate a plurality of contacts, the insulator surface including a plurality of contact locations for locating the plurality of contacts;

a plurality of power contact locations on the insulator surface, the power contact locations designated for power signals; and

a plurality of ground contact locations on the insulator surface, the ground contact locations designated for ground,

wherein the power and ground contact locations lie in a single row on the insulator surface, and

wherein a first power contact location is next to a first ground contact location, and wherein a second power contact location is next to a second ground contact location.

13. The connector of claim 12, further comprising:

a power contact at each of the plurality of power contact locations; and

a ground contact at each of the plurality of ground contact locations;

14. The connector of claim 12, wherein every power contact location on the insulator surface is next to a ground contact location on the insulator surface.

15. The connector of claim 12, wherein the connector is a male plug connector for connecting to a corresponding female receptacle connector.

16. The connector of claim 12, wherein the connector is a female receptacle connector for connecting to a corresponding male plug connector.

17. An electronic device comprising the female receptacle connector of claim 16.

18. A connector comprising:

a housing designed to accommodate contacts in sequentially numbered contact locations, the housing including;

a first set of contact locations designated for DisplayPort signals, wherein the first set of contact locations includes two auxiliary contact locations for a DisplayPort auxiliary channel, the two auxiliary contact locations being in consecutively numbered contact locations.

19. The connector of claim 18, wherein the first set of contact locations further include:

a hot plug detect contact location that is at a contact location consecutive with the two auxiliary contact locations, the hot plug detect contact location designated for a hot plug detect signal.

20. The connector of claim 19, further comprising a contact at the hot plug detect contact location, the contact for carrying the hot plug detect signal, wherein the hot plug detect signal is used as an interrupt request.

21. The connector of claim 20, wherein the interrupt request is configured to enable a source device to detect when a sink device is attached.

22. The connector of claim 18, further comprising:

contacts at the first set of contact locations designated for carrying DisplayPort signals.
