Optical disc drive and flexible cable assembly therein
View Patent ↗An optical disc drive including a chassis, a circuit board and a traverse is provided. The traverse includes a carrier, a pick-up head module, a spindle motor module and a flexible flat cable. The carrier has an opening. The pick-up head module is movably disposed in the opening. The spindle motor module disposed on the carrier is located at one side of the pick-up head module. The flexible flat cable disposed in the opening has two connection ends respectively connected to the pick-up head module and the circuit board. The pick-up head module located at a first position enables the flexible flat cable to have a bending portion protruding towards a direction opposite to the position of the spindle motor module. The pick-up head module located at a second position extends the bending portion. The first position is closer to the spindle motor module than the second position is.
1. An optical disc drive, comprising:
a chassis;
a circuit board disposed on the chassis and having a connector; and
a traverse disposed in the chassis, wherein the traverse comprises:
a carrier having an opening;
a pick-up head module movably disposed in the opening and having a connector positioned above a bottom of pick-up head module; and
a spindle motor module disposed on the carrier and located at one side of the pick-up head module, wherein the spindle motor module is used for carrying an optical disc above the pick-up head module; and
a flexible flat cable disposed in the opening and having two connection ends connected to the connector of the pick-up head module and the connector of the circuit board, respectively, wherein a portion of the flexible flat cable other than the connection end connected to the connector of the pick-up head module is fixed to the bottom of the pick-up head module;
wherein the pick-up head module located at a first position enables the flexible flat cable to have a bending portion, the bending portion protrudes towards a direction opposite to the position of the spindle motor module, the pick-up head module located at a second position extends the bending portion, and the first position is closer to the spindle motor module than the second position is.
2. The optical disc drive according to claim 1 , wherein the pick-up head module comprises a connection port, a direction of a slot of the connection port is perpendicular to the circuit board, and the connection end connected to the pick-up head module is inserted into the slot of the connection port.
3. The optical disc drive according to claim 1 , wherein the flexible flat cable is folded to form a folded edge.
4. The optical disc drive according to claim 3 , wherein portions of the flexible flat cable located at two sides of the folded edge are mutually fixed.
5. The optical disc drive according to claim 1 , comprising:
a reinforcement board, wherein at least a portion of the flexible flat cable is fixed on the reinforcement board.
6. The optical disc drive according to claim 5 , wherein the reinforcement board and the flexible flat cable are folded together to form a folded edge.
7. The optical disc drive according to claim 6 , wherein the folded edge is located around an edge where the reinforcement board and the flexible flat cable are mutually fixed, and the folded edge faces the direction opposite to the position of the spindle motor module.
8. The optical disc drive according to claim 6 , wherein the folded edge is located at a position where the flexible flat cable is not overlapped with the reinforcement board and the folded edge faces the position of the spindle motor module.
