The present invention relates to a connection structure of a USB connector and a method of using various memories using the same.

More specifically, in order to reduce the complexity due to the USB hub used to connect multiple devices and the high cost of manufacturing, the connection structure of the USB connector is provided on both sides to control various devices. It relates to the connection structure of the USB connector to enable the use of the various memory using the same.

In general, USB refers to a universal serial bus, which refers to a device that makes it easy to connect a device to a computer without opening a PC. USB uses standard port and plug combinations to connect devices such as printers, modems, scanners and digital cameras. The advantage of this bus is the ability to easily add, delete, or move devices. In order to connect each device currently used (keyboard, joystick, scanner, modem, digitizer, mouse, infrared connection, etc.), an interface between each device must be built in.

As a result, the additional cost is included in the manufacturing cost of the PC, and general-purpose equipment such as a keyboard and a mouse have been used for a long time, and there is no problem in using the interface. You have to consider the matching problem for all systems. As a result, if you are a beginner using a computer, you may not be able to use the equipment at all because of difficulties in connecting new devices or due to hardware compatibility problems.

The emergence of USB (USB) has the great advantage of being able to connect and connect these external devices and the devices developed in the future into a single, simple connection. Of course, plug and play, which is currently being developed and used for easy installation, is included as standard.

Looking at the connection method of the USB (USB), the overall structure is a tree structure. It's like connecting an external SCSI device, similar to an external SCSI device having input and output interfaces at the same time. Thus, there are two ports on the USB device, one to the upper USB port and one to the lower USB port. In this way, 127 devices can theoretically be connected.

As mentioned above, the USB can be connected to 128 devices in one wire in theory. Of course, one connects USB to a PC, so the total number is 127. This is in large part derived from the connection of the SCSI, which is called Daisy Chanin. However, when connecting to a film, a USB hub is used. It has a tree structure branching from one hub, whereas the daisy chain has an annular, straight structure. Thus, the connectivity is relatively convenient, but the structure itself is a bit more complicated.

Referring to Figures 1 and 2 in more detail with respect to the connection structure and hub (USB) of the USB connector (USB), Figure 1 shows a conventional USB connector structure of the USB 1, 2, 3, 4 wires of 4 can be connected to the USB port of the other terminal is located on the inner side of the protective case can be controlled by the hub after connecting various devices as shown in FIG. Has a structure.

However, when using two devices, as described above, a separate USB hub (HUB) is used, but when using a USB hub (HUB), there is a problem in that the unit cost increases and the size of the product increases.

The present invention has been made to solve the problems described above, in order to reduce the complexity due to the US hub (USB) hub and the high cost of production due to the connection structure of the USB connector on both sides by providing a plurality of devices ( Memory (USB) connector to enable the control of (memory),
