[Prior Art] • Press 'Flexible Flat Cable' (Flexible Flat Cable), referred to as flexible cable or FFC, is a combination of PET insulation material and extremely thin tinned flat copper wire through high-tech automation equipment production line. Data cable. 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. The general flexible cable is subdivided into a three-layer structure, which is a stacking manner of the upper insulating layer, the wire layer and the lower insulating layer from top to bottom, and the flat _ & flat copper wires are separated from each other in the wire layer, and a part thereof Exposed to both ends of the flexible cable to form a guiding point. When the flexible cable is connected between the two systems, the guiding point on either end of the flexible cable is in electrical contact with one of the systems, and each guiding point receives The incoming signal is transmitted to the corresponding guiding point on the other end of the flexible cable, and is transmitted to the other system to achieve the purpose of signal transmission between the two systems. However, as consumer electronics continue to move toward light, thin, short, and small, for example, in mobile electronic devices such as smart phones and tablets, in order to match the miniaturization and portable nature of mobile electronic devices. In design, it is necessary to reduce the lateral width of the flexible cable, and the conductor layer in the general flexible cable is composed of a plurality of tinned flat copper wires arranged in parallel, so the lateral width of the cable is required. Need to have a proper distance size' when the conventional flexible cable is to be assembled in a small-sized narrow shape (four) 'Because the lateral width of the unremovable cable is properly bent (four) small size, (4) often does not work smoothly The problem of plugging a flexible cable into a narrow and small space of a small size. [New content] The horizontal width of the conventional flexible cable is necessarily a certain distance. Because the horizontal width of the flexible cable cannot be appropriately reduced by 2 folds, it is often impossible to make the soft cable into the ground. The problem of small and narrow spaces. The present invention provides a flexible flat type, including a flexible cable, 2 a plurality of wires arranged in parallel, and an insulating layer covering the wires, and the ends of the mother wires are exposed to the insulating layer. Conduction: 'The front end of the soft (4) front end with the exposed guiding surface of the first contact flexible cable is provided with a second contact point of the exposed guiding surface. The wires include at least the first type of line and function Different from the number 』==::= road; wherein the flexible cable is formed by using a plurality of strips, and each slit is located between any one and does not cut through the front and rear ends of the flexible cable. The long strip is folded over the entire line to form at least one first overlapping portion and a second overlapping portion. That is, the first type of line is located at the first overlapping portion, and the second type of line is located at the second overlapping portion, and the sum of the widths of the first overlapping portion and the second overlapping portion is smaller than the original width of the flexible wiring. The flexible flat cable provided by the present invention uses a cutter to cut a strip on a flexible wire to form a plurality of strips, and the strips are folded and overlapped to form at least two overlapping portions, due to overlapping The structure of the part allows the lateral width of the flexible cable to be smoothly and effectively reduced, so that the problem that the conventional flexible cable cannot be smoothly inserted into a narrow space of a small size can be solved. In addition, wire cutters of different functional properties are placed on different overlaps, which reduces the problem of electromagnetic interference between different wires. [Embodiment] Referring to the first to fourth figures, the flexible flat cable 1 of the present invention comprises a flexible cable 2 and a plurality of fixing components 3 for fixing the flexible flexible cable 2 'The flexible cable 2 is composed of a plurality of wires 21 arranged in parallel and an insulating layer 22 covering one of the wires 21. The end of each wire 21 has a conductive surface exposed to the insulating layer 22' The front end of the wire 2 is provided with a first contact portion 24 of the exposed guiding surface 23, and the rear end of the flexible cable 2 is provided with a second contact portion 25 of the exposed guiding surface 23, the first contact portion 24 And the second contact portion 25 is respectively used to overlap with a connector (not shown). 2 rows of 2 series _ a plurality of strips 20 extend along the plurality of turns of the wires to cut the flexible wires 2 to form a complex, 卩 26, each slit 20 is located between any two wires 21 Wear soft, _ line 2 at both ends of the money, so as to maintain the integrity of the overall structure of the flexible cable 2 and provide a certain degree of institutional strength. The long strip portion 26 is folded over the entire line to form a first-overlapping portion 27: a first heavy vertical portion 28, and in the structure of the first overlapping portion 27 and the second overlapping portion 28, the elongated portions 2 The 6 series are overlapped with each other in parallel, and the sum of the widths of the first overlapping portion 27 and the second overlapping portion 28 is smaller than the original width of the flexible wiring 2. In the present embodiment, the wires 21 include a -type-type line 211 and a second type of line 212 having a function different from that of the first type of line 211, wherein the first type of line 211 is located at the first overlapping portion 27, the second The type line 212 is located in the second overlapping portion 28, and the first type, the road 211 is a high frequency signal line 'the second type line 212 is a non-frequency signal line' because the second type line 212 is susceptible to the first type The electromagnetic interference of the line is such that the tm贞 line 211 and the second type line 212 are respectively disposed on the first overlapping portion 27 and the second reddening portion 28, and the first overlapping portion 27 and the second overlapping portion 28 are There is again a separation distance 29 to avoid electromagnetic interference of the second type of line 212 from the first type of line. However, the first type of line 211 is a power line, and the second type line 212 is a signal line. The first type line 211 and the second type line 212 are between M423342.
