Abstract
Description
The present invention relates to a USB OTG memory device, and more particularly, to a USB OTG memory device capable of charging a smart phone.
BACKGROUND ART [0002] With the recent increase in data stored in a smart phone, a USB (Universal Serial Bus) on-the-go (OTG) memory device is increasingly used as an external memory.
USB OTG is a modified universal serial bus (USB) standard that can be operated between portable devices such as personal digital assistants (PDAs), MP3 players, and mobile phones without the involvement of a host computer.
In other words, the USB OTG standard provides a Host Negotiation Protocol (HNP) that allows each device to perform host functions within a limited range to allow point-to-point communication between peripherals, Two protocols have been added to the existing USB 2.0 standard: Session Request Protocol (SRP), which maintains connections only when requested. The transmission speed of USB OTG is used only in LS (low speed) mode (1.5 Mbps), FS (full speed) mode (12 Mbps) and not in HS (high speed) mode (480 Mbps). Also, the cable and connector are 5 pins with an additional ID pin to select the host or slave.
When connecting the memory supporting the USB OTG standard to the charging port of a portable device such as a smart phone, it is possible to use a variety of external devices such as a mouse, a keyboard, a USB memory, and an external hard disk supporting USB, It can be used like a small notebook.
1 and 2 show a conventional USB OTG memory device.
The conventional USB OTG memory device shown in FIGS. 1 and 2 is an external memory improved to operate between a portable device such as an MP3 player and a smart phone without a host PC, and is a portable device (MP3 player, smartphone, Tablet PC) to recognize the USB memory and use it to store data.
In the conventional USB OTG memory device, a micro USB terminal for connecting to a portable device is attached to one side of a printed circuit board (not shown) mounted inside the main body, and a micro USB terminal for connecting to a computer USB terminal is attached. However, the conventional USB OTG is merely an external memory for reading and writing data stored in a smartphone and a computer, respectively, connected to a smartphone and a computer, and functions as a charging function of a smart phone or a data communication And so on.
SUMMARY OF THE INVENTION The present invention provides a USB OTG memory device capable of charging a smartphone when a smartphone and a computer are connected at the same time.
The present invention also provides a USB OTG memory device capable of simultaneously recognizing an OTG memory and a smartphone memory as external hard drives in a computer, and transmitting or backing up data simultaneously with charging of the smart phone.
A USB memory device according to an aspect of the present invention includes a first connector connected to a portable electronic device and a second connector connected to the computer.
The first connector includes a power supply pin to which a power supply voltage is supplied, first and second data pins to which data is transmitted, and a ground pin to which a ground voltage is supplied, And a ground pin to which a ground voltage is supplied,
At this time, the power pin of the first connector and the power pin of the second connector are electrically connected.
Also, the first and second data pins of the first connector may be electrically connected to the first and second data pins of the second connector, respectively.
The USB OTG memory device according to the embodiment of the present invention can provide a function of charging the smartphone when connecting the smartphone and the computer at the same time.
In addition, the USB OTG memory device according to the embodiment of the present invention provides a function of recognizing the OTG memory and the smartphone memory as an external hard disk at the same time in the computer, and can transmit or backup data simultaneously with charging of the smart phone.

2 is a diagram showing a USB OTG memory device mounted on a smartphone.
3 is a diagram illustrating a USB OTG memory device according to a first embodiment of the present invention.
4 is a diagram illustrating a USB OTG memory device according to a second embodiment of the present invention.
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The present invention may be embodied in many different forms and is not limited to the embodiments described herein.
In addition, since each configuration shown in the drawings is arbitrarily shown for convenience of explanation, the present invention is not necessarily limited to those shown in the drawings
3 is a diagram illustrating a structure of a USB OTG memory device according to a first embodiment of the present invention.
According to the first embodiment of the present invention, a first connector for connecting to a portable device is formed on one side of the USB OPG memory, and a second connector for connecting to a computer is formed on the other side of the USB OPG memory.
The first connector of the USB OTG memory includes a power pin Sv to which a power voltage is supplied, first and second
Meanwhile, according to the first embodiment of the present invention, the power pin (Sv) of the first connector of the USB OTG memory and the power pin (Sv) of the second connector are electrically connected through a wire.
Therefore, when the USB OTG memory according to the first embodiment of the present invention is simultaneously connected to the portable device and the computer through the first connector and the second connector, the power pins of the first connector and the second connector of the USB OTG memory Since the power pins are electrically connected, the portable device can be charged using the power of the computer in the same manner as the portable device is charged using the power of the computer through the conventional USB.
4 is a diagram illustrating a structure of a USB OTG memory according to a second embodiment of the present invention.
According to the second embodiment of the present invention, similarly to the first embodiment of the present invention, the first connector of the OTG memory includes a power supply pin Sv to which a power supply voltage is supplied, first and second data pins And a ground pin GND to which a ground voltage is supplied. The second connector also includes a power pin Sv, first and second
According to the second embodiment of the present invention, the power pin Sv and the first and second
Thus, according to the second embodiment of the present invention, when the USB OTG memory is simultaneously connected to the portable device and the computer through the first connector and the second connector, as in the first embodiment, Since the power pin and the power pin of the second connector are electrically connected, the portable device can be charged using the power of the computer.
According to the second embodiment of the present invention, when the USB OTG memory is simultaneously connected to the portable device and the computer through the first connector and the second connector, the data pins (
Thus, according to the second embodiment of the present invention, data can be transferred or backed up simultaneously with charging of the portable device.
While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, And all changes to the scope that are deemed to be valid.
