The present invention relates to a mobile terminal, and more particularly, by having a plug having a protrusion accommodating groove for accommodating the protrusion of the socket cover, the socket cover being torn by the plug even when the plug is connected to the mobile terminal, or separated from the mobile terminal. The present invention relates to a portable terminal having a plug that does not break away.

In general, a mobile terminal is a wireless mobile communication device that can be used indoors or outdoors by the user as well as on the go. The functions previously limited to transmitting and receiving voices perform various functions such as playing games, listening to MP3s, watching the Internet, and watching TV. Is developing into a device.

In particular, with the rapid development of the MP3 function, the user often hears the earphone connected to the mobile terminal, and accordingly, the battery consumption of the mobile terminal increases, thereby charging the battery of the mobile terminal in a car through a battery charging cable or It is becoming increasingly popular to charge the battery while traveling.

In addition, as the storage capacity of the portable terminal increases significantly, the data stored in the PC or the like may be stored in the portable terminal using a USB or the like, or conversely, the downloaded data using the portable terminal may be used using the USB. Increasingly, they are stored on a PC.

Plugs such as earphones, battery charging cables, or USB (USB) is connected to the socket of the portable terminal body to listen to MP3, charge the battery or transmit data.

Hereinafter, with reference to the accompanying drawings will be described the configuration and operation principle of a conventional portable terminal as follows.

1 is a perspective view showing the configuration of a portable terminal according to the prior art, Figure 2 is a plan view showing a state where the earphone is inserted into the portable terminal of FIG.

As shown in FIG. 1 and FIG. 2, the portable terminal 1 according to the related art includes a terminal main body 10 having a socket 13 provided with an electrical terminal (not shown), and a terminal main body 10. Slider 20 is slidably coupled to the front surface and the earphone 30 is provided with a connector terminal 32 inserted into the socket 13 of the terminal body 10 and electrically connected to the electrical terminal.

Here, the terminal body 10, the number input unit 11 is formed on the front of the terminal body 10 to enter a phone number, and the battery 12 is detachably coupled to the back of the terminal body 10 and The socket cover 14 of the flexible material is formed on the side of the terminal main body 10 and connected to the terminal main body 10 so as to open and close the opening of the socket 13 and an electrical terminal provided therein. It consists of.

In this case, the socket cover 14 includes a socket cover body 141, a protrusion 142 protruding from the socket cover body 141 and fitted into the socket 13, and a socket cover body 141. 10 is connected to the connection portion 143, and is formed on one end of the socket cover body 141 is composed of a protrusion piece 144 that the user can hold with a finger.

In addition, the slide unit 20 includes a display unit 21 for displaying information and a button input unit 22 provided at a lower end of the display unit 21 to turn on or off the power or move a menu. It consists of.

In addition, the earphone 30 is an earphone body 31 and a connector terminal 32 protruding from the earphone body 31 and inserted into the socket 13 to be electrically connected to the electrical terminal of the socket 13. , A lead wire 33 extending from the earphone body 31 and a speaker (not shown) formed at an end of the lead wire 33 and inserted into the ear of the user.

The working principle of the portable terminal 1 according to the related art, which is configured as described above, is as follows.

When the user wants to listen to the MP3 using the mobile terminal 1, the user grips the protrusion 144 of the socket cover 14 covering the opening of the socket 13 formed on the side of the terminal body 10 with a finger. When pulled, the socket cover 14 is opened to expose the electrical terminals of the socket 13.

Therefore, when the connector terminal 32 of the earphone 30 is inserted into the socket 13, the electrical terminal of the socket 13 and the connector terminal 32 of the earphone 30 are electrically connected.

Then, the user inserts the speaker of the earphone 30 into the ear and listens to the MP3 using the portable terminal 1.

However, the portable terminal 1 according to the related art, when the socket cover 14 is opened and the connector terminal 32 of the earphone 30 is inserted into the socket 13, Since the protrusion 142 is pushed by the earphone body 31 and a force is applied to the connection part 143 of the socket cover 14, the connection part 143 is broken and is separated from the mobile terminal 1.

In addition, deformation occurs in the socket cover 14 made of a flexible material, thereby drawing the connector terminal 32 of the ear phone 30 from the socket 13 and the protrusion 142 of the socket cover 14 to the socket. If you want to insert in (13) there was a problem that does not fit properly.

The present invention has been made in view of the above-described problems, by having a plug formed with a projection receiving groove for accommodating the projection of the socket cover, the socket cover is torn or torn by the plug even when the plug is connected to the portable terminal It is an object of the present invention to provide a portable terminal which is not separated from the device.

According to an aspect of the present invention, there is provided a portable terminal including a socket having an electrical terminal, the socket cover having a protrusion formed to open and close an opening of the socket, and inserted into the socket to be electrically connected to the electrical terminal. Provided is a portable terminal including a plug having a connector terminal and a protrusion formed with a protrusion accommodating groove into which the protrusion is fitted.

This means that when the connector terminal of the plug is inserted into the socket, the protrusion of the socket cover is inserted into the protrusion accommodating groove formed in the plug, so that the connection connecting the socket cover from the mobile terminal is broken, or deformation occurs in the protrusion of the socket cover. This is to prevent them.

Here, the socket is configured as an earphone socket, and the plug is configured as an earphone, so that when the connector terminal of the earphone is inserted into the earphone socket, the connection portion connecting the earphone socket cover from the mobile terminal is cut off, or the protrusion of the earphone socket cover. The deformation can be prevented from occurring.

In addition, the socket is configured as a USB socket or a battery socket, and the plug is configured as a USB or battery charging connector, thereby inserting the connector terminal of the USB or battery charging connector into the USB socket or the battery socket. In this case, it is possible to prevent the connection portion connecting the USB socket cover or the battery socket cover from the mobile terminal to be broken or to cause deformation of the protrusion of the USB socket cover or the battery socket cover.

Hereinafter, the configuration and operation principle of a mobile terminal according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

However, in describing the present invention, descriptions of well-known functions or configurations will be omitted for clarity.

3 is a perspective view illustrating a configuration of an earphone provided in a portable terminal according to an embodiment of the present invention, FIG. 4 is a plan view illustrating a configuration of the portable terminal into which the earphone of FIG. 3 is inserted, and FIG. Back perspective view of the.
