Abstract

PURPOSE: A fixing device for fixing a flexible print cable to an actuator is provided to improve reliability on a device through fixing a wire withdrawn from a head on a fixing plate through installing a clip after fixing the fixing plate on the actuator. CONSTITUTION: A fixing plate(30) is fixed on a side wall of an actuator for fixing a flexible print cable. A clip(32) is formed on a front end of the actuator for fixing a lead wire connected to a head. Herein, the clip includes a first opening hole(33) of circular shape, and a second opening hole(34) connected to the first opening hole. Moreover, a combining hole(36) is arranged on the fixing plate for a bolt to be coupled thereto. Thus, a short of the lead wire is prevented in driving the actuator at a high speed while preventing the damage of a disk caused by vibration.

An actuator 70 having a head 61 for reproducing, and an interface device for inputting a signal from the actuator 70.

이와 같이 구성되는 HDD에서 액츄에이터(70)는 피봇 축(72)을 중심으로 일측에 헤드(61)를 구비하는 헤드 짐벌(63)이 다수개 설치되고, 타측은 보이스 코일 모타(66)가 설치되며, 상기 보이스 코일 모터(66)의 구동으로 액츄에이터(70)가 피봇 축(72)을 중심으로 회전하면서 헤드(61)가 디스크(60)의 미디어상에 데이타를 기록 또는 재생하게 된다.In the HDD configured as described above, the actuator 70 includes a plurality of head gimbals 63 including a head 61 on one side of the pivot shaft 72, and a voice coil motor 66 on the other side of the actuator 70. As the voice coil motor 66 is driven, the actuator 70 rotates about the pivot axis 72 so that the head 61 records or plays back data on the media of the disc 60.

위와 같이 작동하는 액추에이터에서 헤드를 구동시키기 위한 전기적 신호 및 보이스 코일 모터를 구동하는 전기적 신호는 외부의 회로기판으로 공급되며, 이러한 신호들은 제2도에 도시한 바와 같이 플렉시블 프린트 케이블(20)을 통해 입출력되며, 상기 플렉시블 프린트 케이블(20)의 선단에서 리드선(52)을 통해 헤드(61)에 신호를 입출력하게 되며, 리드선(52)을 통해 보이스 코일 모터(66)를 구동시키게 된다.In the actuator operating as described above, the electrical signal for driving the head and the electrical signal for driving the voice coil motor are supplied to an external circuit board, and these signals are supplied through the flexible printed cable 20 as shown in FIG. Input and output, the signal input and output to the head 61 through the lead wire 52 at the tip of the flexible printed cable 20, and drives the voice coil motor 66 through the lead wire (52).

그러나 위와 같은 종래의 액츄에이터(10)는 고속으로 회동함에 따라 플렉시블 프린트 케이블(20)이 굴신 운동을 하며 이동하게 되는데, 이때 리드선(52)의 단락현상이 자주 발생하게 된다.However, as the conventional actuator 10 rotates at a high speed, the flexible printed cable 20 moves in a bending motion, and a short circuit of the lead wire 52 frequently occurs.

본 발명은 상기와 같은 문제점을 해소하기 위하여 안출한 것으로써, 별도의 플렉시블 프린트 케이블을 고정시키기 위한 고정판을 액츄에이터에 고정시키고, 상기 고정판에 와이어를 협지하기 위한 클립을 형성하여 헤드로 부터 인출되는 와이어를 고정시킬 수 있도록 함으로서, 기기 동작시 신뢰성을 향상시킬 수 있도록 함에 본 발명의 목적이 있다.The present invention has been made in order to solve the above problems, the fixing plate for fixing a separate flexible printed cable to the actuator, and forming a clip for clamping the wire on the fixing plate to the wire drawn out from the head It is an object of the present invention to be able to fix the, to improve the reliability during operation of the device.

상기 목적을 달성하기 위한 본 발명은 액츄에이터의 측벽에 플렉시블 프린트 케이블의 일단을 고정시키기 위한 고정판을 부착하되, 상기 고정판은 헤드 짐벌측으로 신장되며, 끝단에 리드선을 협지하기 위한 클립을 형성하고, 타측은 절곡되어 플렉시블 프린트 케이블이 자연스럽게 굴신 운동을 하도록 구성됨을 특징으로 한다.The present invention for achieving the above object is attached to the fixing plate for fixing one end of the flexible printed cable on the side wall of the actuator, the fixing plate is extended to the head gimbal side, forms a clip for clamping the lead wire at the end, the other side It is bent and characterized in that the flexible printed cable is configured to bend naturally.

이하 본 발명을 구현하기 위한 실시예를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment for implementing the present invention will be described in detail with reference to the accompanying drawings.

우선 제3도 및 제4도를 참조하여 본 발명의 구성을 설명하면, 액츄에이터(10)의 측벽에 고정수단에 의해 고정되며, 플렉시블 프린트 케이블(20)을 고정하기 위한 고정판(30)은 후측이 절곡되어져 플렉시블 프린트 케이블(20)을 유도하며, 선단에는 헤드(61)와 연결되는 리드선(25)을 고정하기 위한 클립(32)을 형성한 것이다. 상기 클립(32)은 원형의 제1개구(33)와, 상기 제1개구(33)와 연통된 제2개구(34)를 포함하여 조립이 용이하게 한다. 아울러, 상기 고정판(30)의 소정위치에는 볼트가 통과하기 위한 체결 구멍(36)이 구비된다.First, the configuration of the present invention will be described with reference to FIGS. 3 and 4, and the fixing plate 30 for fixing the flexible printed cable 20 is fixed to the side wall of the actuator 10 by the fixing means. It is bent to guide the flexible printed cable 20, and the tip is formed with a clip 32 for fixing the lead wire 25 is connected to the head 61. The clip 32 includes a circular first opening 33 and a second opening 34 communicating with the first opening 33 to facilitate assembly. In addition, a predetermined hole of the fixing plate 30 is provided with a fastening hole 36 through which the bolt passes.

이와 같이 구성되는 본 발명의 작용효과는 우선 고정판(30)에 양면 테이프등의 보조부재를 이용하여 플렉시블 프린트 케이블(20)을 가고정한 후, 볼트(15)등의 고정수단을 이용하여 액츄에이터(10)의 측벽에 고정시킨다.The effect of the present invention configured as described above is to temporarily fix the flexible printed cable 20 to the fixing plate 30 by using an auxiliary member such as double-sided tape, and then to the actuator 10 by using fixing means such as a bolt 15. ) On the side wall.

이후, 헤드(61)로 부터 인출되는 리드선(25)을 상기 플렉시블 프린트 케이블(20)에 접속시키게 되는데, 이때 중간부위를 상기 고정판(30)에서 신장된 부위에 형성된 클립(32)에 고정시킬 수 있게 됨에 따라, 액츄에이터(10)가 고속으로 작동하여도 리드선(25)의 단락이 방지된다.Subsequently, the lead wire 25 drawn from the head 61 is connected to the flexible printed cable 20. At this time, the intermediate portion can be fixed to the clip 32 formed at the portion extended from the fixing plate 30. As a result, the short circuit of the lead wire 25 is prevented even when the actuator 10 operates at a high speed.

또한 보이스 코일 모타(66)의 리드선(27)은 바로 하측에서 짧게 연결되므로 영향을 받지 않게 되는 것이며, 상기 고정판(30)의 일측이 약 135°정도 절곡된 절곡부(35)에 의해 플렉시블 프린트 케이블(20)이 자연스럽게 굴곡되어 PCB기판측으로 향하게 되어 액츄에이터 구동시 플렉시블 프린트 케이블이 원활하게 굴신 운동을 할 수 있게 되는 것이다.In addition, since the lead wire 27 of the voice coil motor 66 is shortly connected at the lower side, the lead wire 27 is not affected, and the flexible printed cable is formed by the bent part 35 in which one side of the fixing plate 30 is bent by about 135 °. (20) is naturally bent toward the PCB substrate, so that the flexible print cable can be flexed smoothly when the actuator is driven.

상기한 바와 같이, 본 발명에 의하면 액츄에이터의 고속 구동시에도 리드선의 단락을 방지할 수 있으며, 진동에 의한 디스크의 손상을 미연에 방지하여 접착제의 사용을 배제하여 개스로 인한 디스크 손상 및 경화현상을 방지하여 신뢰성을 향상시킬 수 있게 되는 것이다.As described above, according to the present invention, even when the actuator is driven at high speed, short circuit of the lead wire can be prevented, and damage to the disk due to vibration can be prevented in advance, and the use of adhesive can be eliminated to prevent disk damage and hardening due to gas. It is possible to improve the reliability by preventing.
