Referring to the second to fifth figures, the flexible cable 2 of the flexible flat cable structure 1 of the first figure has not been cut into the original structures of the line portions 4, 5 and the strip portion 6. A schematic view, a partial exploded view, a partially enlarged schematic view, and a partial cross-sectional view. 5 M425373 The flexible cable 2 is composed of a plurality of pre-processed wires 21 arranged in parallel and an insulating layer 22 covering the pre-processed wires 21. Each of the pre-processed wires 21 includes an abutting portion having a contact surface 23. 211. A body portion 212 having an original width D1 and a buffer portion 213 between the abutting portion 211 and the body portion 212, wherein the abutting portion 211 and the buffer portion 213 are exposed outside the insulating layer 22 to facilitate subsequent abutting portions. 211 is calendered to form the contact surface 23. Each pre-machined wire. '21 before the wire is covered with the insulation layer 22, it will be subjected to one or more times of pre-calendering to form a non-circular cross section, and the pre-processed wire 21 includes an upper portion. The surface 214, the lower surface 215, the left side surface 216 and the right side surface 217, the upper surface 214 and the lower surface 215 are in a planar shape and are disposed in parallel with each other. The left side surface 216 and the right side surface 217 are in a planar shape and are left and right. Symmetrical relative arrangement, the left side surface 216 and the right side surface 217 are respectively connected to the left and right sides of the upper surface 214 and the lower surface 215, and the width of the upper surface 214 is substantially equal to the width of the lower surface 215, and the width of the left side surface 216 is substantially Etc. The width of the right side surface 217, the upper surface 214, the lower surface 215, the left side surface 216 and the right side surface 217 form the outer surface of the pre-machined wire 21. Each of the pre-processed wires 21 has an original width D1, that is, a maximum distance between the left side surface 216 and the right side surface 217. The pre-processed wires 21 are exposed to the insulating layer 22 after the wire is covered with the insulating layer 22. After the re-calendering process, a plurality of contact faces 23 are formed. Each of the contact faces 23 has a contact width D2, and the contact width D2 is greater than 6 the original width D1, so that the contacts S 23 are overlapped with the terminals of the mating connector. The insulating layer 22 is composed of an upper insulating layer 221 and a lower insulating layer 222, and an upper metal layer may be disposed on the upper surface of the insulating layer 221 over the flexible wiring 2, and the insulating layer 222 is disposed under the flexible wiring 2. The lower-surface metal layer is disposed on the lower surface to obtain a better electromagnetic wave interference prevention effect. The reinforcing plate 24 is disposed on the front end surface of the flexible cable 2, and the contact surface 23 is directly disposed on the reinforcing plate 24 to increase the strength when the contact surface 23 is butted. The lower portion of the abutting portion 211 and the buffer portion 213 is not left. In the hollow state, the lower insulating layer 222 may be left under the abutting portion 211 and the buffer portion 213, and the reinforcing plate 24 may be disposed under the lower insulating layer 222. Since the first spacing ^ between the adjacent two body portions 212 is greater than the second spacing P2 between the adjacent two abutting portions 211, the larger first spacing P1 is beneficial to the subsequent cutting and dividing operation, and the cutting failure can be reduced. The resulting process yield is reduced. By the foregoing structural characteristics, the flexible flexible cable 2 of the present invention can cut through the rear end thereof by using all the slits 26, and the slits 26 extend along the axial direction of the pre-processed wires 21 and toward the first group of the line portions 3 to The flexible cable 2 is cut to form a second group of line portions 4 and a third group of line portions 5 which are separated from each other. The slits 26 are located between any two pre-processed wires 21 and are cut through the rear end of the flexible cable 2 while utilizing A plurality of slits 27 extend along the axial direction of the pre-processed wires 21 to cut the flexible wires 2 to form a plurality of strips 6 on the second group of line portions 4 and the second group of line portions 5, Each slit 27 is located between any two pre-processed wires 2i and is not cut through the front and rear ends of the flexible cable 2.

The first group of line portions 3 are clamped. It is disposed between the lower casing 321 and the upper casing 322, so that a connector structure can be formed. However, the first connector joint 32 of other forms can also be applied in the present invention. The number of pre-processed wires 21 of the first set of line portions 3 is equal to the number of pre-processed wires 21 commonly included in the second set of line portions 4 and the third set of line portions 5. In other embodiments, the first set of line portions 3 The number of pre-processed wires 21 may be greater than the number of pre-processed wires 21 commonly included in the second set of line portions 4 and the third set of line portions 5, that is, a portion of the pre-fastened wires 21 are cut at the slits 26. The flexible cable 2 is removed to match the circuit design of the docking end. The slit 26 divides the rear end of the flexible cable 2 into the second group of the line portion 4 and the third road portion 5, and in order to increase the mechanical strength of the separated second group of the line portion 4 and the second group of the line portion 5, At least a portion of the second group of line portions 4 is fixed to the third group of line portions 5 by, for example, tape bonding. The bottom portion of the slit 26 is the first group of line portions 3'. The portion of the second group of line portions 4 adjacent to the bottom of the slit 26 is fixed to the third group of line portions 5, so that the external force can be prevented from being respectively applied to The slits 26 caused by the second group of line portions 4 and the third group of line portions 5 grow and extend into the first group of line portions 3 to cause structural damage of the first group of line portions 3. Please refer to the seventh and eighth figures, which is a schematic view and a top view of the flexible cable 2 of the flexible flat cable structure 1 after the plurality of strips 6 are bent and folded. . Each of the strip portions 6 has a first fold line 61 and is bent along the first fold line 61 in a first direction to form a folded portion 60, each strip portion 6 having a second fold line 62 and bent in a second direction along the second fold line 62 The fold 60 is formed between the first fold line 61 and the second fold line 62. The plurality of strips 6 are folded to form a plurality of folded portions 60, and the folded portions 60 are overlapped with each other in parallel so that the width W1 of the folded portions 60 is smaller than the original width W2 of the flexible cable 2, thereby achieving The purpose of reducing the lateral width of the flexible cable 2 is reduced. In the present embodiment, the longitudinal direction of the folded portion 60 of each strip portion 6 is close to the axial direction of the pre-machined wire 21 perpendicular to the flexible cable 2, although other tilting angles may be used. Each of the strips 6 includes four pre-machined wires 21, and may be designed to include other numbers of pre-machined wires 21, and substantially the number of pre-machined wires 21 included in each of the strips 6 is greater. The width of the formed fold 60 is also increased along with it. In addition, for the purpose of fixing, protecting or adjusting the electrical impedance, a wrapping material 7 is further provided to wrap around the folding portions 60 to fix the folding portions 60 to the M425373, wherein the wrapping material 7 is insulated. The material is made of, for example, an acetate cloth, but is not limited thereto, and the wrapping material 7 can also be made of a metal material such as a conductive cloth, so that the effect of preventing electromagnetic wave interference can be increased. It is worth mentioning that the wrapping material 7 also surrounds the second group of line portions 4 and the third group of line portions 5, thereby fixing the second group of line portions 4 and the third group of line portions 5 together. In addition to enhancing the mechanical strength of the second set of line portions 4 and the third set of line portions 5 separated by the slits 26, the second group of line portions 4 and the third group of line portions can be reduced by wrapping 5 features of the width and size. In this embodiment, the pre-processed wire 21 is a wire structure formed by pre-processing the metal wire, so that the left side surface 216 and the right side surface 217 may have a circular arc shape, and the left side may be in a plane shape. The arc length of the face 216 is substantially equal to the arc length of the right side face 217, and other surface configurations may also occur during the pre-machining process. Since the upper surface 214 and the lower surface 215 of the pre-processed wire 21 are in a planar shape, it is advantageous to bond the upper insulating layer 221 and the lower insulating layer 222 to the pre-processed wire 21 from above and below during the wire bonding process. In order to increase the manufacturing yield of the lower insulating layer 222, the pre-processed wire 21 and the upper insulating layer 221 in the wire bonding process, the ratio of the height Η of the upper surface 214 of the pre-processed wire 21 to the lower surface 215 from the original width D1 is increased. The system is designed to be between 1: 2 and 1: 4, and the ratio of the optimum height Η to the original width D1 is 1:3, which can achieve the purpose of improving the yield of the 10 high-line process and can be beneficial. Subsequent cutting and slitting processing operations. In summary, the flexible flat cable structure of the present invention is formed by cutting a tool at the end of the flexible cable to form two or more circuit portions, and then assembling the circuit portions separately by two or more different types. The connector connector can form a one-to-many connector configuration to solve the problem that the conventional flexible cable cannot be matched with the miniaturization and portable space design of the mobile electronic device. In addition, the flexible cable with pre-machined wires can improve the process yield of forming more than two sets of line parts due to the large spacing between adjacent two pre-machined wires during cutting operations, thereby reducing production costs. Furthermore, the flexible dividing line cuts the dividing line to form a plurality of long strip portions, and the long strip portions are folded and overlapped to form a folded portion structure, and the folding portion structure can reduce the original lateral width of the flexible cable, so that The flexible cable is smoothly inserted into a small and narrow space to meet the needs of the miniaturized space design of the mobile electronic device.
