What is necessary is to solder to the objective lens holder 260 and the PCB wire holder 310, the objective lens holder 260 is fixed by the screw 156 and installed in the correct position by the coil fixing piece 158, The wire holder 310 is installed at the correct position by the center protrusion 312 and the auxiliary protrusion 314 so that the assembly position is accurately maintained when soldering the upper, lower, left, and right 4 wires 290, 292, 294, and 296, and wire insertion is performed. The wire insertion holes 132, 134, 136, and 138 formed in the plate 130 have an inlet extending outward, so that the wires 290, 292, 294, and 296 having a diameter of only 0.15 mm can be easily inserted, thereby simplifying work.

이상 설명한 바와 같이 본 발명은 와이어고정구멍이 천공된 베이스의 일면에 몸체를 설치하고, 몸체의 선단에는 와이어삽입공이 천공된 와이어삽입판을 설치하며, 와이어삽입판과 베이스사이에는 피시비와이어홀더가 설치되는 홀더설치판을 설치하고, 홀더설치판과 베이스사이에는 대물렌즈홀더설치부를 형성시킨 것으로, 본 발명에 의하면 대물렌즈홀더와 피시비와이오홀더가 정확한 위치로 설치되므로써 와이어의 납땜시 조립위치가 정확하게 유지되고, 와이어삽입공의 입구가 외측으로 확장되어 있으므로 와이어의 삽입이 용이하여 작업을 용이하게 할 수 있으며, 베이스와 와이어삽입판에 형성된 와이어고정구멍과 와이어삽입공이 수평으로 일치되어 있으므로 상,하,좌,우에 끼워져 납땜되는 와이어사이의 평행도가 양호하게 되므로써 광 픽업 액추에이터의 조립완료시 트래킹동작 및 포커싱동작을 하게 되는 대물렌즈홀더의 동작이 원활해지게 되는 유용한 효과를 갖는다.As described above, in the present invention, a body is installed on one surface of the base where the wire fixing hole is drilled, and a wire insertion plate having a wire insertion hole is installed at the tip of the body, and a PCB wire holder is installed between the wire insertion plate and the base. The holder mounting plate is installed, and the objective lens holder mounting portion is formed between the holder mounting plate and the base. According to the present invention, the mounting position of the wire is precisely soldered because the objective lens holder and the PCB holder are installed at the correct positions. It is retained and the inlet of the wire insertion hole is extended outward so that the wire can be easily inserted to facilitate the work. , The parallelism between the wires to be inserted and soldered to the left and right is good It has a useful effect the operation of the objective lens holder to which the tracking operation and the focusing operation during assembly of the actuator to be completed to be smooth.
