This application is related to U.S. Design Patent Application No. ______, titled UNIVERSAL SERIAL BUS (USB) PORT SYSTEM and filed simultaneously herewith, and U.S. Design Patent Application No. ______, titled UNIVERSAL SERIAL BUS (USB) PLUG SYSTEM and filed simultaneously herewith; the disclosures of which are incorporated herein by reference in their entireties.
Embodiments described herein relate to electrical connectors. More particularly, embodiments described herein relate to universal serial bus (USB) port and plug systems.
USB is a connector standard that defines cables, connectors, and communication protocols used in a bus connection, communication, and power supply between computing devices and electronic devices. More particularly, USB is a serial interface that is often used in place of RS232 serial interfaces and parallel interfaces to connect peripheral devices (e.g., mice, keyboards, printers, etc.) to computers (e.g., desktop and laptop computers). Many computers are equipped with multiple USB connectors, each of which is designed to mate with a respective USB plug. A typical USB connector is configured with electrical contacts that are designed to couple to electrical contacts external to the USB connector in order to perform data transfer and power supply functions. Some of the electrical contacts of the USB connector are used to couple electrical contacts of a USB plug to the electrical circuitry of the USB connector, whereas some of the electrical contacts of the USB connector are used to couple the electrical circuitry of the USB connector to conductive traces formed on a motherboard of a computer. Electrical traces on the motherboard route electrical signals between the electrical circuitry of the USB connector and electrical circuitry mounted on the motherboard, such as, for example, a USB controller that is connected to a main processor of the computer.
USB plugs and ports are available in a variety of sizes and shapes. In addition, there are many different electrical and computing applications for USB technologies. For at least these reasons, there is a continuing need for improved USB plug and port systems of varying shapes and sizes for different applications.

In this example, opening 106 is sized and shaped to receive and engage a 12 Volt (V) USB version 2.0 plug. The slot 110 defines a notch 113 or stop component configured to prevent insertion of a 24 V USB plug, while permitting insertion of a 12 V USB plug.
In an alternative example, for example, the opening 106 and slot 110 may be sized and shaped to receive and engage a 24 V USB version 2.0 plug. A slot or other stop component may be formed in the slot 110 to prevent insertion of a 12 V USB plug, while permitting insertion of a 24 V USB plug. In the example above, a USB version 2 plug, a USB version 3 plug, a 12V USB plug, a 24V USB plug are described. In embodiments of the disclosure, however, various versions or types may be applied. Openings 106 and 108 may be sized and shaped to receive and engage any given USB version plug, respectively. Slots 110 and 112 also may be structured to receive and engage any given USB version plug, respectively.
Multiple pads may be positioned within the slot 106 and arranged to be operably connected to a USB version 2.0 plug of 12 V type. Particularly, the slot 106 may form multiple openings 111 wherein the pads may be positioned. Alternatively, the pads may be arranged to operably connect to any type of USB version 2 plug. The pads may be configured for carrying any suitable type of electrical signal including, but not limited to, a ground, a D+ signal, a D− signal, and a VCC signal.
Multiple pads 114 are positioned within the slot 106 and arranged to be operably connected to a USB version 3.0 plug. Alternatively, the pads 114 may be arranged to operably connect to any type of USB version 3 plug. The pads 114 may be configured for carrying any suitable type of electrical signal including, but not limited to, a ground, a D+ signal, a D− signal, a VCC signal, a StdA_SSRX signal, a StdA_SSRX+ signal, a ground drain, a StdA_SSTX+ signal, and a StdA_SSTX-signal. One of the pads 114 may function as a power pad for delivery of power to a USB version 3 device.
The system 100 may include USB version 2 circuitry and USB version 3 circuitry (not shown in the figures) contained within the interior of the housing 102. The circuitry may be operably connected to the pads within the openings 111 and the second pads 114. The circuitry may be configured to suitably connect the pads within the openings 111 and 114 for transmission of the USB version 2 and version 3 signals to and from pins 116 arranged on and extending from the side 104D of the housing 102.
