Device for protecting CD ROM static electricity

Abstract

The invention discloses a static protection device of a CD-ROM driver. A chute is respectively fixed on two sides of the internal part of the CD-ROM driver, and a conductive foam-cotton is arranged in one chute, one end of which contacts a casing and the other end thereof projects from the chute to contact a guide way, one end of the guide way, which extents out of the CD-ROM driver, is provided with a clamp hook; formed by conductive materials. Two guide ways slide in virtue of salvers supported on two sides. An electronic part is arranged on the salver and a bottom of the salver is covered by a conductive soleplate for protection. A conductive elastic body is arranged on the lower part of the salver, and a braking gap is formed at a front end of the salver and the clamp hook is arrangedon the moving route of the braking gap. A contact end part is bent near the braking gap to contact the protection soleplate. An upward sliding-contact end part projects from the back end of the elastic body to electrically contact the guide ways so as to protect the protection soleplate and guide ways through electrical connections.

Description

technical field [0001] The invention relates to an optical drive, in particular to an electrostatic protection device used in the optical drive to eliminate static electricity charged by an operator to avoid damage to precision electronic parts. Background technique [0002] Since the optical drive contains quite sophisticated electronic components, the user must touch the optical drive during operation. Therefore, the static electricity on the body will accumulate in the conductor, or run around through the conductor in the optical drive. Once it is conducted to the precise electronic components, Very vulnerable to damage. [0003] Such as figure 1 and figure 2 As shown, it is an existing optical drive 10 showing the inside and the back, wherein the metal casing 11 has a hollow area, and fixed plastic sliding grooves 111 are arranged on both sides, each accommodating a metal guide rail 112 Sliding, one end of the guide rail 112 is blocked by the block 113 on the casing ...

AI Technical Summary

Problems solved by technology

However, the circuit of the flexible cable 18 is relatively small. Although it can eliminate a small amount of static electricity, it still cannot be quickly eliminated for a large amount of sudden static electricity, which will cause static electricity to accumulate and cause damage.

In addition, the flexible cable 18 is mainly used for the transmission of signals and data, allowing a large amount of static electricity to pass through the flexible cable 18, which is likely to interfere with the signals and data transmitted at the same time, and affect the reliability of the optical drive signal

Furthermore, when the hook 114 recessed in the guide rail 112 formed by the sheet metal blocks the stopper 122 made of plastic, especially when subjected to a large impact, the stopper 122 is often damaged, causing the tray and the slide rail to be stuck. The tray cannot advance and retreat normally

Therefore, there are still problems to be solved urgently in the static protection device and the braking of the tray in the existing CD-ROM drive.
