Problems solved by technology
Although this structure provides the correct connection of flexible multi-core cables, the use of connectors not only increases the unit cost of the product, but also requires an interface corresponding to the connector
[0011] In addition, the manufacturing process becomes cumbersome because it is necessary to form locking portions for fastening the connectors at the opposite ends of the flexible multi-core cable
In addition, the locking part tends to tilt to one side during its formation, thereby increasing the defect rate of the final product while interfering with the continuous production of flexible multi-core cables

Embodiment Construction
[0024] Hereinafter, typical embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[0025] In the drawings, the same components are denoted by the same reference numerals, and well-known functions and structures will be omitted for brevity.
[0026] refer to Figure 2 to Figure 5 , a flexible multi-core cable 100 for an optical disc drive according to an embodiment of the present invention is formed by inserting a plurality of flat wires 130 between an upper film 110 and a lower film 120, and the flexible multi-core cable 100 is based on the flexible multi-core cable 100 The folded middle part is centered and divided into a fixed part 100a and a moving part 110b. Here, the fixed part 100a is directly connected to a printed circuit board (PCB) 210 in the main body 200 of the optical disc drive by soldering, and the moving part 100b is connected to the interface 250 of the tray 230, which can be slid in and out in response...

The present invention relates to a flexible multi-core cable for an optical disk drive. In the flexible multi-core cable, one end of a fixing part is provided with a fixing alignment membrane, and oneend of a moving part is provided with a moving alignment membrane. The fixing alignment membrane is connected to the lower side end of a flat conductor wire; the lower side end is exposed by removingthe end of the upper membrane and the end of the lower membrane to ensure the contact so that the flat conductor wires are aligned and are directly connected to a pattern of PCB of the main body by welding mode. The moving alignment membrane is connected to the other lower side end of the exposed flat conductor wire so that the flat conductor wire can be fixedly aligned and is directly welded onthe interface of the tray capable of responding to the operation of the user to slidingly pass in and out.
Description
technical field [0001] The present invention relates to a flexible multi-core cable for an optical disc drive, and more particularly, to a flexible multi-core cable for an optical disc drive having a plurality of flat wires ( flat conductive wire), the plurality of flat conductive wires are aligned to allow precise soldering instead of connectors to connect the flexible multi-core cable, thereby reducing defective connections of the flexible multi-core cable and reducing manufacturing costs. Background technique [0002] As is well known in the art, a flexible multi-core cable (FFC) is made by thermally bonding a plurality of flat wires (copper wires) arranged at regular intervals on a substrate made of polyester (PET) or polyimide by using a thermal bonding (thermal bonding) device. It is made of amine (PI) between the flexible heat-resistant films on the upper side and the lower side of the flexible multi-core cable (ie, the opposite side of the flexible multi-core cable)....
