New description: [New technical field] This creation is about a flexible flat cable structure, especially for a flexible flat cable structure that has both electromagnetic wave interference prevention and aesthetic appearance. [Prior Art] Flexible Flat Cable (Flexible Flat Cable), referred to as flexible cable or FFC, is a data line that is pressed together with a high-tech automation equipment line using PET insulation and extremely thin tin-plated flat copper wire. Cable structure. The flexible cable is a component for signal transmission, and has its own advantages of arbitrarily flexible and high signal transmission capability, and thus is widely used in many electronic products. Generally, the flexible cable is divided into three layers, and the upper layer is sequentially stacked with the upper insulating layer, the wire layer and the lower insulating layer. The plurality of flat copper wires are arranged in parallel in the wire layer, and the ends are exposed to softness. The front and rear ends of the cable are used to form a guiding point. As consumer electronics continue to evolve in a light, thin, and short direction, in order to accommodate the miniaturization and thinning of portable electronic devices, the lateral width of the flexible cable must be reduced in size. Therefore, some operators have developed a tool to cut the middle section of the flexible cable to form a plurality of long cables, and the long cables are bent and stacked to form a beam line structure, because the beam line structure makes the flexible cable originally The lateral width is reduced, so that the problem that the general flexible cable 3 M441914 cannot be inserted into a small size space can be solved. The wire harness structure must be fixed to prevent looseness of the plurality of long wires. Conventional practice is to use a tape wrapped around the wire harness structure to achieve the purpose of fixing a plurality of long cables. However, such a flexible cable having a wire harness structure can solve the problem that the conventional flexible cable cannot be inserted into a small-sized space, but since it is not provided with any protective structure for preventing electromagnetic interference (EMI), it is easily exposed to electromagnetic waves. Interference causes adverse effects, which in turn leads to customer complaints. In addition, a part of the wire harness structure is exposed to the outside of the product structure during use, and the exposed portion usually causes an unattractive appearance of the product. [New content] It is known that the flexible cable with the beam-line structure does not have a protection structure for preventing electromagnetic interference, so it is easily affected by electromagnetic interference and causes adverse effects, resulting in customer complaints. In addition, some of the wire-wound structures are exposed outside the product structure during use, and the exposed parts often cause unsightly appearance. The present invention provides a flexible flat cable structure comprising a flexible cable and a conductive layer, wherein the flexible cable has a plurality of partial wires, each of the plurality of wires comprising a plurality of metal wires arranged in parallel and covering the metal wires An insulating layer, the partial lines are stacked on each other to form an overlapping portion, and the overlapping portion includes a bending portion. The conductive layer surrounds the overlap portion, and the conductive layer corresponds to the bend region as a black conductive layer. 4 The flexible flat cable structure provided by the present invention uses a surrounding-conductive layer to surround the periphery of the overlapping portion and the conductive layer corresponds to a red-conducting f-folding area-black conductive layer. The purpose of preventing electromagnetic interference is 'and at the same time has an aesthetically pleasing effect to solve the problem of customary complaints. In addition, since the cutting seam is directly formed on the grounding wire, 'they* will be reduced by the f-planting of the plurality of flat copper wires in the dragon-off line, so that the cutting line can be turned into a poor yield. The problem. [Embodiment] Please refer to the first and second diagrams for the perspective view and cross-section of the flexible flat wire structure. The third and fourth figures show a schematic view of the flexible flat wire mirror structure of the present invention, which is sequentially folded and folded and wound around the conductive layer.

In the present embodiment, the flexible cable 1 has a front connecting portion 14, a rear connecting portion 15, and a main body portion 16 between the front connecting portion 14 and the rear connecting portion 15, and the front connecting portion 14 and the rear connecting portion 15 A plurality of contacts (not shown) are respectively disposed on the upper portion 16 , and the partial wires 13 and an aluminum foil layer 17 are disposed on the main body portion 16 . The front connecting portion 14 is provided with a casing 2 to form a wire end connector. The casing 2 is provided with a plurality of grounding elastic pieces 21 for overlapping with the aluminum enamel layer 17 on the body portion 16. A reinforcing plate 3 is provided on the rear connecting portion 15. It is worth mentioning that, since the size of the gap between the plurality of metal wires 11 is reduced to be smaller than the width of the metal wires 11 due to the effect of the reduction, the present invention directly places the slit 10 in the metal wires 11. On the grounding conductor, rather than the insulating layer 12 of the prior art where the gap region of the metal wire 11 is not provided, the problem of the poor cutting yield of the prior art can be solved. Each of the sub-lines 13 includes a plurality of metal wires 11 arranged in parallel and an insulating layer 12 covering the metal wires 11 . The metal wires 11 include a plurality of signal wires and ground wires (not labeled). After the ground wires are cut by the cutter Exposed to the insulating layer 12, the partial lines 13 are bent and then stacked on each other to form an overlapping portion 18. As shown in the third figure, the remaining edges 13' located on the two sides of the dividing lines 13 can be arbitrarily selected. In the present embodiment, it is selected to directly cut off the remaining edge 13' and leave only a plurality of partial lines 13, the width of the overlapping portion 18 is smaller than the width of the flexible cable 1, so that the smooth The overlapping portion 18 is assembled in an elongated accommodating space such as a hinge or a hinge. In addition, the overlapping portion 18 includes a bending portion 181 which is outside the product mechanism and must be subjected to a rocking test of repeated bending. As shown in the fourth figure, the conductive layer 4 is surrounded by In the present embodiment, in the embodiment, since the bending region 181 is exposed to the structure of the hinge, the conductive layer 4 corresponds to the bending region 181 as a black conductive layer 41 for the purpose of aesthetic appearance, and the conductive layer 4 is a silver conductive layer 42 corresponding to the bend region 181. However, the conductive layer 4 may be a black conductive layer 41 corresponding to the bend region 181, that is, the entire conductive layer 4 is a black conductive layer. 41. Alternatively, the black conductive layer 41 may be replaced by a dark conductive layer, which may also be aesthetically pleasing. In this embodiment, the black conductive layer 41 is made of a black conductive cloth. The silver conductive layer 42 is made of a silver conductive cloth, and the black conductive layer 41 and the silver conductive layer 42 are each a separate element, and the black conductive layer 41 is Adjacent to the silver conductive layer 42 and contacting the silver conductive layer 42 to form electrical conduction. The conductive layer 4 surrounding the overlapping portion 18 is electrically connected to the grounding wire and the aluminum foil layer 17 which are exposed outside the respective branch lines 13, thereby achieving the purpose of preventing electromagnetic interference and improving the control capability of the impedance (Impedance). . In addition, a conductive paste is disposed between the conductive layer 4 and the overlapping portion 18, and the conductive adhesive electrically conducts the conductive layer 4 and the grounding wires of the respective sub-lines 13 and the aluminum foil layer 17.
