Antistatic structure for optical disc device
The present invention relates to an antistatic structure for an optical disc device. An optical pick-up unit module of an optical disk device is installed on a chassis and the chassis is movably installed in a lower cover of the device. Furthermore, the antistatic structure includes at least one upper connecting portion capable of contacting with the optical pick-up unit module and at least one lower connecting portion capable of contacting with the lower cover. Whereby, the static electricity generated by the optical pick-up unit module can be conducted to the lower cover through the upper and lower connecting portions so as to attain the antistatic discharge (ESD) protection effectively.
1. An antistatic structure for an optical disk device, said optical disc device having a lower cover and an optical pick-up unit module used to read data stored in an optical disk, said antistatic structure comprising:
a chassis movably installed in said lower cover and said optical pick-up unit module being disposed on said chassis, in which at least one flexible upper connection portion and at least one flexible lower connection portion are provided on said chassis;
wherein said upper connection portion contacts with said optical pick-up unit module and said lower connection portion contacts with said lower cover,
wherein said lower connection portion is a crossbeam on which surface is provided with a protrusion which contacts with said lower cover.
2. The antistatic structure according to claim 1 , wherein said upper and lower connection portions are integrated with said chassis.
3. The antistatic structure according to claim 1 , wherein said upper connection portion is in the form of an arm which has a free end got in touch with said optical pick-up unit module.
4. The antistatic structure according to claim 3 , wherein said free end of said upper connection portion is further bended downward in an angle so as to increase the contact area with said optical pick-up unit module.
5. The antistatic structure according to claim 1 , wherein said lower connection portion is in the form of an arm which has a free end got in touch with said lower cover.
6. The antistatic structure according to claim 5 , wherein said free end of said lower connection portion is further bended upward in an angle to form an inclined guide plane.
7. The antistatic structure according to claim 1 , wherein said protrusion is slightly interfered with a rim of said lower cover.
8. The antistatic structure according to claim 1 , wherein said crossbeam and said protrusion are integrated with said chassis.
9. An antistatic structure for an optical disk device, said optical disc device having a lower cover and an optical pick-up unit module used to read data stored in an optical disk, said antistatic structure comprising:
a chassis slideably installed in said lower cover and said optical pick-up unit module being disposed on said chassis,
wherein an upper connection portion is formed integrated on said chassis to contact with said optical pick-up unit module and a lower connection portion is formed integrated on said chassis to contact with said lower cover,
wherein said lower connection portion is a crossbeam on which surface is provided with a protrusion which contacts with said lower cover.
10. The antistatic structure according to claim 9 , wherein said upper and lower connection portions are flexible.
11. The antistatic structure according to claim 9 , wherein said upper connection portion is in the form of an arm.
12. The antistatic structure according to claim 11 , wherein said arm has a free end being bended downward in an angle so as to increase the contact area with said optical pick-up unit module.
13. The antistatic structure according to claim 9 , wherein said lower connection portion is in the form of an arm.
14. The antistatic structure according to claim 13 , wherein said arm has a free end being bended upward in an angle to form an inclined guide plane.
15. The antistatic structure according to claim 9 , wherein said protrusion is slightly interfered with the rim of said lower cover.
