A slim optical disk drive includes a lower housing, a tray, a protection plate, a flexible cable and an isolated part. The tray is supported by two slide rails for sliding in or sliding out of an opening of the lower housing. The protection plate is for covering a bottom of the tray. The flexible cable includes a plurality of wires. The flexible cable extends toward the opening and is stuck on the lower housing. A curved area is formed by bending the flexible cable near the opening. The flexible cable is accommodated between the protection plate and the lower housing when the tray is slid inside the lower housing. The isolated part is disposed on the protection plate. The isolated part is for shielding predetermined wires of the plurality of the wires to reduce noise of signals.

Slim optical disk drive capable of reducing noise of signals

An ESD protection device for a disk drive comprises a guide at two inner sides of the disk drive. A conductive sponge, one end contacting the case and the other protruding end contacting one of two conductive rails, is disposed in one guide. A hook is formed at one end, jutting out of the disk drive, of the rail. The rails support two sides of the tray, having electric elements disposed thereon and its bottom being covered by a conductive traverse cover, sliding. A conductive elastic stopper disposed at the bottom tray has an indentation formed at the front end to position the hook on the indentation's moving path, a contact part bent to electronically connect to the cover next to the indentation, and a sliding part formed at the rear end by protruding upwards to electronically connected to the rail, to electronically connect to the cover and the rail.

Electrostatic discharge protection device for optical disk drive

The invention provides a protection device for protecting a flat cable in an optical disk drive. The protection device includes a casing, whereon a main board is fixed inside the casing, and an opening is formed at a front edge of the casing. The protection device further includes a tray disposed inside the casing in a slidable manner, a circuit board disposed on a bottom of the tray, the flat cable connected to the main board and the circuit board, a cover disposed on the bottom of the tray, and a support frame connected to the cover and protruding towards a rear of the casing. The support frame is disposed on the bottom of the tray and adjacent to a position, where the flat cable is connected to the circuit board, for holding the flat cable and preventing the flat cable from dropping.

Protection device for protecting a flat cable

An electrostatic discharge protection device for an optical disc drive is provided. A rail disposed on the casing of the disc drive has an opening. A guide bar is slidable disposed on the rail. A conductive elastic plate is fixed around the opening on the rail. The elastic plate has an elastic-pressing end leaning against the guide bar through the opening, and a protrusion electrically contacting the casing. A tray supported by the guide bar to move in and out of the casing has an underside covered by a protection bottom plate. A conductive strip-shaped elastic element is fixed on the tray by a fixing screw, which fastens the protection bottom plate on the tray. As such, the elastic element is in contact with the protection bottom plate; besides, the elastic element also leans against the guide bar, so as to dissipate electrostatic discharge by the guide bar.
