본 고안은 하드디스크 드라이브의 FPC(Flexible Printed Circuit) 커넥터 구조에 관한 것으로, 특히 액츄에이터의 선단부의 헤드와 후단부의 보이스코일모터(Voice Coil Motor: VCM)를 제어하도록 FPC와 PCBA(Printed Circuit Board Ass'y)를 전기적으로 연결하는 하드디스크 드라이브의 FPC 커넥터 구조에 관한 것이다.The present invention relates to the structure of a flexible printed circuit (FPC) connector of a hard disk drive. In particular, the FPC and PCBA (Printed Circuit Board Ass') control the head of the actuator and the voice coil motor (VCM) of the rear end of the actuator. It relates to the structure of the FPC connector of the hard disk drive that electrically connects y).
일반적으로, 하드디스크 드라이브의 기구물 중, HDA(Head Disk Ass'y)내의 FPC(10)상의 신호선은, 제1도에 도시된 바와 같이, 헤드 신호를 전달하는 헤드신호선패턴(11)과 VCM에 제어신호를 전달하는 VCM신호선패턴(12)으로 이루어져 있다.In general, among the mechanisms of the hard disk drive, the signal lines on the FPC 10 in the head disk assembly (HDA) are connected to the head signal line patterns 11 and the VCM that transfer the head signals, as shown in FIG. It consists of a VCM signal line pattern 12 for transmitting a control signal.
이러한 신호선들(11, 12)은, 제2도에 도시된 바와 같이, 베이스(16)에 고정된 커넥터(13)를 통해 HDA밖의 회로물인 PCBA(14)쪽과 전기적으로 연결되어 헤드신호를 헤드로부터 PCBA(14)쪽으로 전달하여 리드(Read)동작을 하거나 PCBA(14)상의 VCM제어회로로부터의 VCM 제어신호를 FPC(10)를 통해 VCM에 전달하여 서보제어동작을 하게 된다.These signal lines 11 and 12 are electrically connected to the PCBA 14, which is a circuit outside the HDA, through the connector 13 fixed to the base 16, as shown in FIG. To the PCBA 14 to perform a read operation or to transfer the VCM control signal from the VCM control circuit on the PCBA 14 to the VCM via the FPC 10 to perform the servo control operation.
이와 같은 전달경로는, PCBA(14)상의 신호패턴, PCBA상의 소켓(15), FPC의 커넥터(13), FPC상의 신호패턴 및 헤드와이어 또는 VCM 코일와이어 등의 순으로 형성되는데 이들 중, PCBA상의 소켓의 홀(15A)과 FPC상의 커넥터의 핀(13A)이 결합하면 PCBA측과 HDA측이 전기적으로 연결된다.Such a transmission path is formed in the order of the signal pattern on the PCBA 14, the socket 15 on the PCBA, the connector 13 of the FPC, the signal pattern on the FPC, and the head wire or the VCM coil wire. When the hole 15A of the socket and the pin 13A of the connector on the FPC are coupled, the PCBA side and the HDA side are electrically connected.
그러나, 이와 같은 FPC의 커넥터의 연결방법은, PCBA측의 소켓과 커넥터의 형상이 복잡하여 제작비가 높으며, 조립시 이들 커넥터와 소켓의 결합이 용이하게 않으며, 장시간 사용에 의하여 소켓 또는 커넥터의 상태가 불량하게 되어 전기적연결이 단절되는 경우가 발생하여 장비의 신뢰도가 낮아지는 문제점이 있었다.However, the connection method of the connector of the FPC has a high manufacturing cost due to the complicated shape of the socket and the connector on the PCBA side, and it is not easy to connect the connector and the socket during assembly, and the state of the socket or the connector is long due to use. There was a problem in that the electrical connection is disconnected to be poor and the reliability of the equipment is lowered.
또한, 서보신호 입력시 HDA만 장비에 장착하여 서보신호를 입력하게 되는 데, 서보신호 입력 장비의 포고핀(POGO PIN) 블럭이 FPC 커넥터 장착 패드에 장착되어 HDA의 밖으로 노출되어 있는 FPC 커넥터상의 핀과 포고핀이 접촉하게 된다. 이 때, 서보신호 입력장비와 HDA와 전기적 연결이 이루어지는 데 FPC커넥터가 핀타입이므로 정확한 접촉이 어렵고 특히, 소형 커넥터를 사용하는 경우에 더욱 자주 그와 같은 문제가 발생하여 서보신호입력이 안되거나 잘못되는 불합리한 점이 있었다.In addition, when the servo signal is input, only HDA is mounted on the equipment to input the servo signal.The pogo pin block of the servo signal input equipment is mounted on an FPC connector mounting pad and is exposed on the outside of the HDA pin. And pogo pin are in contact. At this time, since the FPC connector is a pin type to make electrical connection with the servo signal input device and the HDA, it is difficult to make accurate contact. Especially, when a small connector is used, such a problem occurs more often, and the servo signal input fails or is incorrect. There was an irrational point of becoming.
따라서, 본 고안은 전술한 문제점을 감안하여 이루어진 것으로, 본 고안의 목적은, HDA와 PCBA를 연결을 견고하게 하여 장비의 신뢰성을 향상시키며, 커넥터의 구성을 단순하게 함에 따라 제작을 용이하게 하여 제작비를 낮추는 하드디스크 드라이브의 FPC 커넥터 구조를 제공하는 것에 있다.Therefore, the present invention has been made in view of the above-described problems, and the object of the present invention is to strengthen the connection between the HDA and PCBA to improve the reliability of the equipment, and to simplify the configuration of the connector to facilitate the production cost It is to provide a structure of the FPC connector of the hard disk drive lowering.
