Description

Portable Device Accessories {Accessory for Mobile Phone or PMP}

The present invention relates to accessories used for mobile communication terminals such as PCS, mobile phones, and MP3 players. In particular, portable devices that can be connected to a portable device and used as a necklace or a string to charge or transmit and receive data as necessary It is about accessories.

The number of mobile phone subscribers such as PCS and mobile phones has increased at a high rate all over the world, and the number of mobile phone subscribers has surpassed the number of wireline subscribers in Korea. . In addition, portable multimedia player (PMP) devices, such as portable MP3 players, are gradually expanding into the market. In the case of a mobile communication terminal or a portable multimedia player, power is supplied from a lithium-ion, lithium-cadmium, lithium-hydrogen battery, etc., which are coupled to the main body, and charged using a separate charging cradle, a charger, and the like.

In addition, these mobile communication terminals or PMPs are recently made small and light, and are frequently used in the form of hanging around the wrist using a string or the like using neckbands to listen to music or make a phone call.

Universal Serial Bus (USB), on the other hand, is a standard for computer peripheral connectivity developed by major computer vendors such as Intel, Compaq, Hewlett-Packard, Lucent, Microsoft, NEC, and Philips. USB provides a way for computer users to easily connect peripherals using external ports without opening the chassis of the system. USB simultaneously supports a large number of peripherals connected to a single USB port, allowing multiple peripherals such as printers, scanners, digital cameras and speakers to be used simultaneously from a single computer. 1 illustrates an example in which various devices are connected using USB. In this example, various devices such as a computer 111, a USB hub 112, 113, a phone 114, a printer 115, a camera 116, a touch pad 117, and the like are connected to a USB network. Connected via

USB also automatically detects and installs devices, allowing users to easily add devices using the Plug and Play method. That is, users can easily connect with each other as long as the device supports USB. USB also makes it easy to expand the number of ports using a USB hub so that device usage is not limited by the limited number of ports.

2 shows a USB cable. The USB cable consists of four wires, which supply power to the device through the power line (VBUS) and ground (GND). VBUS is + 5V at the source. Data is conveyed by serial transmission of the differential signals of D + and D-.

According to the USB 1.1 specification, the USB full-speed transfer rate is 12Mbps and the low-speed transfer rate is 1.5Mbps. In addition, according to the popular USB 2.0 specification, the data transfer speed is 480Mbps, which is 40 times higher than the USB 1.1 specification. Because USB 2.0 has backward compatibility, you can use the same cables, connectors, and software as in the USB 1.1 specification.

Most recently released PCs and notebook computers are equipped with USB ports, and the number of devices supporting the USB port is increasing.

At present, despite the development of battery technology, the charging time of a battery used in a mobile communication terminal and a portable multimedia player has some limitations, and the charging of such a mobile terminal and a portable multimedia player is limited. It is true that there are many inconveniences. In particular, as today, various forms of media are spread, such media are played, and various functions are used in one device, and thus power consumption increases, and a method for easily recharging a battery is being devised.

Looking at the conventional charging method of such a device can be considered how to use a dedicated charging device provided by each device manufacturer and how to charge using a cigarette jack (Cigar Jack) in the car.

When a mobile communication terminal or a PMP is purchased, manufacturers provide a charger exclusively for the corresponding device, but this has the following disadvantages. First, these chargers are less portable due to their volume. Therefore, in general, these chargers are usually fixed at home or at work. For this reason, if the battery of the device is exhausted in a place without such a charger, there is a disadvantage in that the device cannot be used eventually. Secondly, current devices often receive their source from a computer and use it in connection with a computer for backup purposes. USB cables for computers are widely used for this purpose. There was an inconvenience to carry.

On the other hand, even in the case of the charging method using a cigar jack in the car, it is difficult to charge the car without the car because it must be charged.

The present invention is intended to solve this inconvenience, the purpose is to provide a charging function using a necklace string or a cell phone string that almost all mobile communication terminals or PMP is spread as a basic specification.

Another object of the present invention is to enable simple charging and data communication wherever a computer is located even without carrying a separate device.

The present invention to achieve this purpose

A terminal connector having a UART connector connected to a UART port of the portable device at one side and a female terminal connected to a communication / charging cable connection at the other side; and

A communication / charging cable connector having one end coupled to the female terminal and having a screw thread on an outer circumferential surface thereof, and a USB terminal connector connected to a USB terminal of a computer at the other side, and a main body to which the UART connector is fitted at an upper side of the USB terminal connector; Wow

One side provides a string for use in a portable device with a coupling that is rotatably coupled to the thread of the communication / chargeable cable connection.

The main body unit may have a communication conversion chip for performing a UART to USB communication conversion.

The main body may include a power conversion unit for receiving power from a computer and converting the power into a power suitable for a wireless terminal, a charging state display unit for displaying a charging state of the portable device, and converting the data from a computer to provide the portable device. It may include a data interface unit.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 3 is a complete view of a portable device accessory according to an embodiment of the present invention, Figure 4 is an exploded view of the accessory of Figure 3, when assembled as a necklace or string of a typical portable device in one state, the need for charging If possible, disconnect the terminal connector from the body (1).

The main body part is a terminal connector and the main body is fitted to the bar, when the first body portion and the second main body 12, which is coupled to the separation, the first main body 11 is a communication port of the mobile phone device on one side, For example, having a UART connector 13 connected to the UART port, the cover 15 is formed on the other side, the second body portion is shown on one side USB terminal connector 14 which can be connected to the USB terminal of the computer, the other side is communication The cable part, the cord coupling part, and the cord 2 coupled to the cord coupling part remain.

When the cover formed on the opposite side of the UART connector of the first body part is removed, the female terminal 16 to which the communication / charging cable connection port is connected comes out.

In this state, when the user rotates the cord coupling part to which the cord is connected, the cord and the first cord coupling part connected to the cord may be separated from the second body part and the second coupling part may be connected to the female terminal formed on the first body part. The male terminal 17 is formed, and the user inserts the male terminal into the female terminal.

In this state, when the user plugs the USB connector into the USB port of the computer, it is charged.

As described above, the present invention converts the power provided from the computer into a power suitable for a wireless terminal and provides a data service connection and charging device installed in a PC that receives data from the computer and converts the data. It is possible to simultaneously perform data service connection and charging of a wireless terminal without a separate connection cable.
