Description:
CROSS REFERENCE TO RELATED APPLICATION 
       [0001]    This application is related to U.S. Design Patent Application No. ______, titled UNIVERSAL SERIAL BUS (USB) PLUG SYSTEM and filed simultaneously herewith; the disclosure of which is incorporated herein by reference in its entirety. 
     
    
     FIELD 
       [0002]    Embodiments described herein relate to electrical connectors. More particularly, embodiments described herein relate to micro universal serial bus (USB) plugs and systems. 
       BACKGROUND 
       [0003]    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. 
         [0004]    Micro USB plugs and ports, such as micro USB version 2 and 3 plugs and ports, has a dimension smaller than other USB types of plugs and ports. More particularly, a micro USB is a newer generation specification of mini USB having a dimension reduced by about 60% when compared to mini USB. Such size and dimension can be beneficial for use in small electronics and computing devices. 
         [0005]    Micro 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 micro USB plug and port systems of varying shapes and sizes for different applications.

       [0029]    The presently disclosed subject matter is described with specificity to meet statutory requirements. However, the description itself is not intended to limit the scope of this patent. Rather, the inventors have contemplated that the claimed subject matter might also be embodied in other ways, to include different steps or elements similar to the ones described in this document, in conjunction with other present or future technologies. Moreover, although the term “step” may be used herein to connote different aspects of methods employed, the term should not be interpreted as implying any particular order among or between various steps herein disclosed unless and except when the order of individual steps is explicitly described. 
         [0030]      FIGS. 1-8  illustrate different views of an example micro USB plug system  100  in accordance with embodiments of the present disclosure. Particularly, the figure shows a micro-B USB version 2 plug system. Referring to  FIGS. 1-8 , the system  100  includes a housing  102  having sides  104 A- 104 F. The sides of the housing  102  form an interior  800  therebetween. The housing  102  may be made of a suitable plastic or other type of rigid material as will be understood to those of skill in the art. In this example, the housing  102  is generally an elongated cube in shape; however, it should be understood that the housing  102  may be any suitable shape depending on the application. The housing  102  may be suitably sealed for preventing entry of moisture or contaminants within the interior defined by the sides  104 A- 104 F and shown in  FIG. 8 , which illustrates a cross-sectional, side view of the system  100 . 
         [0031]    An opening  106  is defined within side  104 A of the housing  102  for receipt of a micro USB connector, such as a mating micro USB plug. A slot  108  formed in the interior of the housing  102  and extends from the opening  106  towards the interior. The slot  106  is structured to receive a micro USB version 2 connector. In an alternative example, for example, the opening  106  and slot  108  may be sized and shaped to receive another suitable type of connector. The slot  108  can function as a constraint feature that prevents engagement with non-micro USB version 3 equipment. 
         [0032]    Multiple micro USB pins  110  are positioned within the slot  108  and arranged to be operably connected to a USB version 2 connector. Alternatively, the pins may be arranged to operably connect to any type of micro USB version connector. Pins  110  may include, but not limited to, a V CC  pin, a transmit pin, a receive pin. In addition, a ground pin  112  and a power pin  114 . The ground pin  112  extends further from the interior than the power pin  114 .
