Wear-proof structure for a flexible circuit in an optical disk drive

Abstract

A wear-proof structure for a flexible circuit disposed within a casing of an optical disk drive is provided. The casing has an entrance. A tray is disposed within the casing and its underside is covered by a protection plate. The protection plate has one end bent upwardly to form a tail with an arc-shaped cross-section. The flexible circuit includes a fixed portion and a movable portion. The fixed portion is immovably disposed on the casing. The movable portion is connected to one end of the fixed portion and extended toward the other end of the fixed portion to form a folded end with the fixed portion, and the folded end is immovably disposed near the entrance. A wear-proof layer is covered on the folded end; besides, the wear-proof layer has a wing outstretched the folded end and pasted on the casing to enhance the wear-proof ability of the flexible circuit.
