USB modem device {USB MODEM DIVICE}

The present invention relates to a USB modem device capable of two-axis rotation, and more particularly, it is possible to improve the reception rate by easily changing the position of the wireless transmission and reception module through two-axis rotation around the USB port provided in the computer, The present invention relates to a USB modem device that allows for relatively efficient use of adjacent USB ports.

The rapid technological development of IT is equipped with an environment in which desired information can be easily accessed through new products such as mobile terminals or digital appliances. In particular, with the convergence of various services based on digitalization and the Internet, the technology of the network has become very important in the trend of broadband and ultra-high speed services.

With the development of such network technology, not only simple text information can be obtained through a network, but also voice and video can be simultaneously transmitted in real time. In addition, new means of communication, such as integrated services digital networks or cable modems, have been developed to transmit vast amounts of information.

Also proposed as the next generation technology is the DSL or Asymmetric Digital Subscriber Line.

In using such communication means, a cable modem is expensive to install and use, and a wireless modem has been developed to compensate for this. Also, as the user's working environment changes, the development of wireless modems is accelerating as more and more users use laptop computers from traditional desktop computers.

Here, the term "wireless modem" refers to a device for wirelessly connecting to the Internet using a laptop computer or a personal portable terminal and transmitting or receiving data or making a call through a wireless public network. The wireless modems are mainly in the form of PCMCIA (PC card) and CF, which are supplied to laptop computers or PDAs.

In accordance with this trend, conventional wireless modem devices have been generally installed to install a wireless modem using a universal serial bus (USB) for convenience of portability and installation. Here, the conventional wireless modem device in more detail as follows. 1 is a perspective view showing a conventional wireless modem device.

As shown here, the USB modem device 10 is composed of a USB pin 11 and the housing 12. At this time, the USB pin 11 is inserted and connected to the USB port of the computer, and has a wireless modem (not shown) inside the housing 12 to allow the computer to transmit and receive data wirelessly.

Here, USB is a device that allows a peripheral device to be connected to a computer. In recent years, USB is widely used in that a plurality of peripheral devices can be connected than a serial port and data transmission and reception speed is high.

In addition, due to these advantages, in the case of a laptop computer or a desktop computer, a plurality of USB ports are formed adjacent to each other so as to easily connect a plurality of peripheral devices, thereby facilitating connection and management of external devices.

However, the conventional USB modem device has the following problems.

First, there is a problem that it is difficult to change the direction of the USB modem device in order to improve the reception rate.

Secondly, when a conventional USB modem device is connected to a USB port of a computer, there is a problem in that it cannot use an adjacent USB port due to its size, or it is inconvenient to install and use.

Third, there is a problem that the location itself of the laptop computer, UMPC or desktop computer to which the USB modem device is connected is improved in order to improve the reception rate in a place where reception rate is lowered or in a shaded area.

One object of the present invention for solving the above problems is to provide a USB modem device that is easy to change the direction of the USB modem device to improve the reception rate.

Another object of the present invention is to provide a USB modem device that can change the orientation of a housing so that an adjacent USB port can be used when connected to a USB port of a computer.

It is still another object of the present invention to provide a USB modem apparatus that can relatively improve a reception rate without changing a location of a laptop computer, a UMPC, or a desktop computer to which a USB modem device is connected in a place where a reception rate is lowered or in a shaded area.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, a USB modem device is a wireless transmission and reception module for transmitting and receiving data wirelessly through a digital subscriber line (DSL), to form a hollow first shaft on one side And a USB connector forming a USB pin to be connected to a USB port of a computer on the other side, a cable connecting the transceiver module and the USB pin, and accommodating the wireless transceiver module therein to form a second through hole.

That is, when the USB connector connected to the rotating unit 200 rotates in the direction of the housing 100, the USB pin 310 is disposed in the inward direction of the accommodating part 110 and the accommodating part ( 115, the USB pin 310 is accommodated.

In this case, one surface of the accommodating part 115 that faces the accommodating part 110 may have a curved shape similar to one surface of the accommodating part 110 in which the second through hole 102 is not formed. do. In addition, the accommodating part 115 has a shape in which a part of the housing 100 is recessed to prevent the USB pin 310 from rotating more than a predetermined level. That is, the accommodating part 115 may be provided to serve as the first adjusting part 330 described above.

Next, as shown in Figure 9, the USB modem device further comprises a third adjusting unit 230 for adjusting the rotation angle of the rotating unit 200 in a step, the third adjusting unit 230 And a gear member 105 and an elastic member 205.

The gear member 105 is formed in the inner surface of the second through hole 102 to have a valley and the floor in the sawtooth shape in the radial direction, the elastic member 205 is relative to the outer peripheral surface of the second shaft 201 Protruded to have a predetermined elasticity in the radially outward direction of the second shaft 201, and is formed in a shape corresponding to the shape of the gear member 105.

That is, when the second shaft 201 is inserted into and connected to the second through hole 102, the virtual circle formed by the floor of the gear member 105 and the second shaft 201 are formed. The outer circumferential surface is corresponding, and the elastic member 205 is inserted into the bone, so that the rotary unit 200 is rotated only when a predetermined or more force is applied to the rotary unit 200 with respect to the elasticity. There is an effect that can prevent the rotation of the rotating unit 200 is not.

In addition, since the third adjusting unit 230 serves to adjust the rotation speed of the rotating unit 200, it may perform a function similar to the second adjusting unit (not shown).

In the present embodiment, the third adjusting unit 230 is provided as being formed in the second through hole 102 and the second shaft 201, but the present invention is not limited thereto or limited thereto. 202 and the connection portion of the first shaft 301, it is also possible to adjust the relative rotation of the rotary unit 200 and the USB connector 300 in stages.

In addition, in the present exemplary embodiment, the first adjusting unit 330 and the third adjusting unit 230 are provided to be independent of each other, but are not limited thereto or limited thereto. For example, the third adjusting unit 230 may be provided at the same time as the first adjusting unit 330. In detail, the gear member 105 of the third adjusting unit 230 may be provided. ) Is provided as a whole radius in the radial direction of the second through hole 102, but it is formed so that only a predetermined angle, for example, an angle of 180 degrees in the radial direction of the first through hole 202. In addition, the elastic member 205 may be disposed on the first shaft 301 so that the USB connector 300 rotates only by the angle at which the gear member 105 is formed, thereby limiting the rotation angle. .

That is, the angle formed by the gear member 105 of the third adjusting part 230 serves as the blocking member 203, and the elastic member 205 serves as the locking member 303. And, accordingly, by appropriately changing the third control unit 230, it is also possible to make the role of the first control unit 330 in parallel.
