This application is based on and claims priority under 35 U.S.C. §119 to a Korean patent application filed on Jan. 4, 2016 in the Korean Intellectual Property Office and assigned Serial number 10-2016-0000335, the disclosure of which is incorporated by reference herein in its entirety.
The disclosure relates generally to a universal serial bus (USB) on-the-go (OTG) device connected between electronic devices to deliver an electric signal between the electronic devices.
USB, short for a universal serial bus, is an industry standard developed by Intel, Microsoft, Compaq, NEC, etc. so as to easily connect peripheral devices to a personal computer and to meet a multimedia environment.
A USB device may have a form of plug connector or receptacle connector, which corresponds to each other. The plug connector has a structure being insertable into the device connector by having a protruding part to be inserted into an insertion hole of the receptacle connector. The receptacle connector has a vertically reversed structure in comparison with the plug connector and thus can be inserted into the plug connector. The plug connector and the receptacle connector may have, at their protruding part, terminals confronting each other and to be in contact with each other. Electric power and data may be delivered through such terminals. In the USB 2.0 standard, terminals are basically formed of four types, i.e., GND, D(+), D(−), and Vcc. Additionally, a certain external devices, such as a mouse, a keyboard, a USB memory, or the like, may be recognized through a USB OTG device including USB micro five pins used in a mobile device.
Unfortunately, the USB OTG device that transmits and receives an electric signal through a printed circuit board (PCB) and cable has several drawbacks, due to use of the PCB and cable, such as an increase in manufacturing cost, a decrease in production rate, a radio frequency (RF) noise caused by soldering between the PCB and cable, and an incomplete prevention of degradation in RF performance.
Various example embodiments of the present disclosure provide a universal serial bus (USB) on-the-go (OTG) device in which at least four pins are arranged, at one ends thereof, in at least parts of a plug connector and also arranged, at the other ends thereof, in at least parts of a receptacle connector.
The USB OTG device according to various example embodiments may include at least four pins for transmitting or receiving an electric signal; a plug connector electrically connected with a USB receptacle connector of a first electronic device through first ends of the at least four pins; and a receptacle connector electrically connected with a USB plug connector of a second electronic device through second ends of the at least four pins. In this USB OTG device, at least portions of the first ends of the at least four pins may be mounted in the plug connector, and at least portions of the second ends of the at least four pins may be mounted in the receptacle connector.
The USB OTG device according to various example embodiments may prevent and/or reduce the occurrence of RF noise and the degradation of RF performance by transmitting and receiving an electric signal through pins integrated between the plug connector and the receptacle connector, rather than using the PCB and cable.
The USB OTG device according to various example embodiments may also prevent and/or reduce the occurrence of RF noise and the degradation of RF performance using a shieldcan integrated with the plug connector and the receptacle connector.
The various example embodiments do not require soldering, thus reducing manufacturing cost and promoting a higher production rate.
The above and other aspects of the disclosure will be more apparent from the following detailed description, taken in conjunction with the accompanying drawings, in which like reference numerals refer to like elements, and wherein:
