본 고안에 따르면, 휴대형 단말기의 SD/MMC 접속부를 배터리부에 위치시켜 SD/MMC 카드를 배터리부에 장착하게 된다.According to the present invention, the SD / MMC connection part of the portable terminal is placed in the battery part to mount the SD / MMC card in the battery part.
이하, 본 고안의 바람직한 실시 예를 첨부한 도면에 의거하여 설명하면 다음과 같다.Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows.
도 2는 본 고안에 따른 SD/MMC 접속부를 가지는 배터리부와 단말기부를 도시한 것으로서, 기존 휴대형 단말기기의 배터리 부에 SD/MMC 접속부가 추가되고 단말기부에는 배터리 접속용 연결부에 SD/MMC 신호를 연결하는 부분만 추가된 형태를취한다.2 illustrates a battery unit and a terminal unit having an SD / MMC connection unit according to the present invention, wherein an SD / MMC connection unit is added to a battery unit of an existing portable terminal device, and the terminal unit supplies an SD / MMC signal to a battery connection unit. Only the parts that connect are taken.
도 3은 본 고안에 따른 SD/MMC 접속부를 가지는 휴대형 단말기의 단면을 도시한 것으로서, 기존의 휴대형 단말기용 배터리에서 가지고 있는 배터리 셀과 전원접속부(7)를 그대로 가지면서 SD/MMC 접속부(6)가 추가된 형태로 구성되어 진다. 전원 접속부(7)의 신호 구성은 배터리 충방전을 위한 BATT신호와 배터리 온도를 나타내는 TEMP와 Ground로 구성되어 지며, 휴대 단말기의 SD/MMC 신호 연결부(5)와 배터리의 SD/MMC 신호 연결부(6)는 도 4의 SD/MMC 신호(15)로 구성되어 진다.3 is a cross-sectional view of a portable terminal having an SD / MMC connection according to the present invention, the SD / MMC connection 6 having the battery cell and power supply connection 7 which are present in a conventional portable terminal battery. Consists of the added form. The signal structure of the power connection unit 7 is composed of a BATT signal for battery charging and discharging, TEMP and ground indicating the battery temperature, and the SD / MMC signal connection unit 5 of the mobile terminal and the SD / MMC signal connection unit 6 of the battery (6). ) Is composed of the SD / MMC signal 15 of FIG.
도 4는 SD/MMC 카드와 신호 규격을 도시한 것으로서, 9개의 신호선을 가지며, MMC Card는 SD Card가 가지는 신호선에서 일부(6개의 신호)만을 사용하게 된다. 1번 핀의 경우 4비트로 동작하는 SD 카드에서만 사용하게 되며 4비트의 데이터 가운데 Data3을 의미한다. 2번 핀은 SD 카드와 MMC 카드에서 모두 사용하는 신호로 명령어를 주고 받으며, 명령어에 대한 응답을 전달하는 신호선이다. 3번 핀과 6번 핀은 SD/MMC 카드와 제어부의 Ground를 연결하는 신호이며, 4번 핀은 전원 공급을 위한 VCC 신호선이다. 5번 핀은 SD/MMC 카드와 제어부의 동기를 맞추기 위한 클럭 신호이며, 7번 핀은 데이터를 주고 받는 Data0 신호이다. 8번과 9번 핀은 SD Card에서만 사용하며, 1비트로 동작하는 경우는 인터럽트와 ReadWait신호로 사용되고 4비트로 동작하는 경우는 데이터의 1번 비트와 2번 비트로 사용되어 진다.4 shows a signal standard with an SD / MMC card, and has nine signal lines, and the MMC card uses only a part (six signals) in the signal line of the SD card. Pin 1 is used only in SD card which operates with 4 bits, which means Data3 among 4 bits of data. Pin 2 is a signal used by both SD card and MMC card to send and receive commands, and it is a signal line that transmits a response to the command. Pins 3 and 6 are signals connecting SD / MMC card and ground of controller, and pin 4 is VCC signal line for power supply. Pin 5 is the clock signal to synchronize SD / MMC card and the controller. Pin 7 is the Data0 signal to send and receive data. Pins 8 and 9 are used only in SD card. When it works with 1 bit, it is used for interrupt and ReadWait signal, and when it works with 4 bit, it is used as 1 bit and 2 bit of data.
도 5는 본 고안에 따라 제작된 휴대형 단말기와 SD/MMC 접속부를 가지는 배터리의 동작을 도시한 것으로서, 휴대형 단말기부에는 SD/MMC 접속 규격을 지원하는 제어부가 존재하며 배터리부에는 SD/MMC의 접속을 위한 커넥터(소켓)가 위치하게 된다. SD/MMC 카드(14)를 SD/MMC 커넥터(10)에 삽입한 후 단말기부와 배터리 부를 결합하면 SD/MMC 카드를 단말기부의 SD/MMC 제어부(13)에서 제어할 수 있게 된다.FIG. 5 illustrates the operation of a battery having a portable terminal manufactured according to the present invention and an SD / MMC connection unit. The portable terminal unit includes a control unit supporting an SD / MMC connection standard and a battery unit connected to the SD / MMC unit. Connector (socket) is located. When the SD / MMC card 14 is inserted into the SD / MMC connector 10 and the terminal unit and the battery unit are combined, the SD / MMC card can be controlled by the SD / MMC control unit 13 of the terminal unit.
이러한 SD/MMC 접속부를 가지는 배터리는 휴대용 단말기에만 적용되는 것은 아니며, 캠코더, 디지털 카메라 등 SD/MMC 접속방식을 가지는 기기에서도 사용이 가능하다.The battery having the SD / MMC connection is not only applicable to a portable terminal, but can be used in a device having an SD / MMC connection such as a camcorder or a digital camera.
이상에서와 같이 본 고안에 의하면, SD/MMC 커넥터를 배터리부에 위치시켜 휴대형 단말기의 부피를 줄일 수 있도록 하며, SD/MMC 접속부가 필요한 경우에만 선택적으로 사용할 수 있는 장점을 가지게 된다.According to the present invention as described above, it is possible to reduce the volume of the portable terminal by placing the SD / MMC connector in the battery unit, and has the advantage that can be selectively used only when the SD / MMC connection is required.
