BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ear microphone of a mobile communication terminal, and more particularly, to an ear microphone incorporating a SIM card which enables the terminal to be miniaturized by installing a SIM card connector of a GSM terminal in a microphone portion of the ear microphone.

In the GSM terminal, which is a mobile communication terminal mainly used in Europe, as shown in FIG. 1, a SIM card 1 recording user's registration information is installed in the terminal 9 and used in many GSM terminals. A SIM card holder is installed inside the pack (2) installation place.

In the GSM terminal having such a structure, it is difficult to reduce the area of the PCB by installing a connector for connecting the SIM card to the PCB, and it is difficult to reduce the volume of the terminal because the SIM card and the connector must be installed in the terminal.

An object of the present invention is to provide a GSM terminal that can be installed to use the SIM card outside the terminal body, that is, the ear microphone in order to reduce the volume of the GMS terminal and allow room for the component mounting area of the PCB.

The present invention forms a SIM card installation slot in the ear microphone of the GSM terminal, and installs a connector for connecting the ear microphone and the main body of the terminal so that the SIM card and the main body installed in the ear microphone can exchange signals.

The ear microphone incorporating the SIM card of the GSM terminal of the present invention is a composite connector having a connection point necessary for transmitting and receiving an audio signal and a SIM card signal with a terminal body, and an audio connected to a terminal to which an audio signal of the composite connector is applied. And a SIM card signal line connected to a signal line, a terminal to which the SIM card signal of the composite connector is applied, a SIM card receptacle connected to the SIM card signal line, and an earphone and a microphone connected to the audio signal line.

The composite connector comprises a conventional earphone plug and / or connector and terminals of a plurality of male and / or connectors formed around the plug and / or connector.

The present invention is also provided with a corresponding composite connector that can be combined with the composite connector, the terminal can be set to enable the call processing the SIM card signal when the ear microphone is connected.

An embodiment of the present invention will be described in detail with reference to the drawings.

The present invention is an ear microphone having a SIM card used in a GSM terminal, and a terminal having a corresponding composite connector corresponding to a composite connector of the ear microphone in order to connect a signal of the SIM card to the terminal.

First, the ear microphone for the GSM terminal is a terminal to which the composite connector 13 having a connection point necessary for transmitting and receiving an audio signal and a SIM card signal with the terminal body 100 and a terminal to which the audio signal of the composite connector 13 is applied. The audio signal line connected to the SIM card signal line connected to the terminal to which the SIM card signal of the composite connector 13 is applied, the SIM card receptacle 11 connected to the SIM card signal line, the earphone 20 and the microphone connected to the audio signal line ( 19) and a SIM card 12 connected to the SIM card signal line.

The composite connector 13 includes a conventional earphone plug 15 and / or connector 16 and a plurality of male terminals 17 and / or connectors 18 formed around the plug 15 and / or the connector 16. It includes terminals.

In general, mechanical connectors have one or more connector elements, which are designed to connect or disconnect the flow of an electrical signal as the two contacts are in contact with or separated from each other.

The plurality of male terminals 17 of the composite connector are pin-shaped, and the connector 18 is tubular and / or cylindrically shaped to receive and wrap the pins. You can install five. Then, the two audio signal lines of the earphone plug can be used for the SIM signal, which can be a total of seven SIM signal lines. As another example, seven cancer means may be used instead of five.

The male terminal 15 may be the same as the earphone plug and connector that are commonly used, and the connector and male terminal for SIM card signal transmission are in any form of a pin that is normally used and a structure suitable for being transferred to this pin. Also available.

In addition, a composite connector can be used in various forms as long as it has a connection terminal, even if the structure is not described above. These connectors are widely used in various types of connectors to connect various components in the field of computer hardware. These connectors may be used. In the embodiment shown in the present invention, the connector element is illustrated or described as a pin or a male terminal, a female terminal in the form of a tube, and the like, but this is only one example and various existing connector elements, for example, a computer or an electronic or electric device. Of course, all of the widely used connectors can be used.

Since the composite connector of the present invention has the same thing as the existing earphone connector in the center, it is also convenient to use by simply plugging in the earphone plug.

The SIM card receptacle 11 is installed at a suitable place among the conductors between the earphone 20 and the composite connector 13 of the ear microphone. In the illustrated example, the SIM card receptacle 11 is installed, which is connected to the SIM card signal line. It is connected. The SIM card 12 usually has seven signal line terminals, and the SIM card receptacle has receiving terminals in contact with the terminals of the SIM card, which are connected to the SIM card signal line. Of course, the SIM card receptacle (11) also has a locking function to hold the SIM card 12 is not easily escaped when inserted.

The terminal body should be provided with a corresponding composite connector 14 corresponding to the composite connector at an appropriate location. This mating composite connector 14 has a connector and / or a plug corresponding to the plug and / or connector of the ear microphone 8.

In the embodiment shown in Figure 3b, the composite connector installed in the ear microphone is an earphone plug 15 and five connectors 18 are formed around the corresponding connector, the corresponding composite connector 14 formed on the terminal body is composed of a composite connector Earphone connector 16 is installed in the center so as to correspond to the five male terminals 17 are formed around it.

When the ear microphone of the present invention is connected to the terminal, and the SIM card connector is inserted into the SIM card receptacle of the ear microphone, it is locked and installed. The registration is made so that communication is possible.

The contact terminals of the composite connector shown in FIG. 3A and the wires connected thereto are A for Audio terminals, B for Ground, C for Vcc, D for Vpp, E for Clock, F for Data (In / Out), and G for RST. It can be used.

The configuration of such a connector is a pin, ie, male, on one side thereof; The corresponding side is a female in the form of a hole.

As described above, the present invention provides a SIM card and a connector thereof to be built in the terminal, thereby providing a large effect in miniaturizing the size of the terminal. In addition, SIM cards can be replaced without removing the battery pack, making it easy to use.
