Abstract: A spindle motor includes a base plate, a stator, and a rotor. The base plate has a plurality of air-guiding holes. The stator includes a bearing portion and a plurality of coil portions. The bearing portion is fixed on the base plate. The coil portions are connected to and surrounded the bearing portion, and are disposed above the air-guiding holes. The rotor is rotatably mounted to the bearing portion and disposed adjacent the coil portions.

Abstract: A tray of an optical disc drive for loading an optical disc in and out of the optical disc drive includes a depression for disposing the optical disc, a hollow space for providing a space for an optical pickup to access data while the optical pickup moves along a radial direction of the optical disc, a depressed portion formed at the middle portion of a rear end of the tray, and a reinforcement means formed of rigid material and disposed at the depressed portion for enhancing rigidity of the tray. The depression and depressed portion are monolithically formed.

Abstract: A mounting structure of an interface jack includes an insulating housing, multiple electrical wires, a first metallic piece, a second metallic piece, and at least one third metallic piece. The insulating housing has an upper surface, a lower surface, a backside surface, a first lateral wall, a second lateral wall and an entrance. The entrance is communicated with a receptacle disposed within the insulating housing. The backside surface is connected with the upper surface, the lower surface, the first lateral wall and the second lateral wall. The electrical wires are arranged inside the insulating housing and extended out of the backside surface of the insulating housing. The first metallic piece is attached on the bottom surface of the first lateral wall. The second metallic piece is attached on the bottom surface of the second lateral wall. The third metallic piece is attached on the lower surface.

Abstract: A shock absorbing structure includes a cushion having a central longitudinal bore. A joint member is embedded in the central bore of the cushion and has a first part and a second part. The first part abuts against the inner side of the bore of the cushion to fix the cushion. The second part longitudinally from one end of the first part and tapers radially inwardly in the longitudinal direction thereof thus, together with the cushion, defining a progressively increasing gap as vibration space for the cushion.

Abstract: A cover hinge structure having self-protection function, which consists of a cylindrical hinge pin and a hook. The hinge pin and the hook are integrated with a body and a cover, respectively. An engaging groove with an opening narrower than the hinge pin forms at the engaging end of the hook. When the cover is lifted to the limit, the action force acted by the pin on the hook from directs toward the opening of the engaging groove and the direction of the action force is the same as the opening direction of the engaging groove. Thus, the pin detaches from the hook automatically before damage to the hinge structure occurs if great force is applied.
