## Abstract

An optical disk drive is disclosed to fix a main board in the casing and a second board under the tray. A flat cable on the bottom of the casing connects the main board with one end, and forms a bent portion to connect the connector of the second board at the other end. A cable protection device close to the connector is fixed under the tray to face the bent portion with an incline for preventing the bent portion from bending.

## Claims

### Claim 1

An optical disc drive, comprising:
a casing;
a main board fixed on a back end of the casing;
a tray slidably moving in and out of the casing;
a second board disposed under the tray, a connector being disposed on the second board;
a flat cable fixed on a bottom of the casing, an end of the flat cable being connected to the main board and the other end of the flat cable forming a bent portion to connect with the connector; and
a cable protection device fixed under the tray and close to the connector, the cable protection device comprising an incline facing the bent portion, and a distance between the incline, slanting from an end near the connector toward a rear side of the optical disc drive, and the bottom of the casing being gradually increasing.

### Claim 2 (depends on 1)

The optical disc drive of claim 1, wherein an acute angle is formed between the incline and a rearward direction of the optical disc drive.

### Claim 3 (depends on 2)

The optical disc drive of claim 2, wherein the acute angle is substantially 30 degrees.

### Claim 4 (depends on 1)

The optical disc drive of claim 1, wherein a bottom of the tray and the cable protection device are integrally formed.

### Claim 5 (depends on 4)

The optical disc drive of claim 4, wherein the cable protection device is a step structure protruding from the tray toward the bottom of the casing.

### Claim 6 (depends on 5)

The optical disc drive of claim 5, wherein the cable protection device is connected to a rear terminal end of the tray.

### Claim 7 (depends on 1)

The optical disc drive of claim 1, wherein a bottom of the tray is covered by a metal plate, and a flange of the metal plate is near the connector and protrudes a rearward direction of the optical disc drive to clip the flat cable with the incline, so as to prevent the flat cable from overbending.

### Claim 8 (depends on 7)

The optical disc drive of claim 7, wherein the flange of the metal plate horizontally protrudes along the rearward direction of the optical disc drive.
