New description: [New technical field] - There is a kind of flexible flat cable, especially for flexible flat cable with knife cutting and slitting operation. [Prior Art] The rapid development of Yuezi Technology has become more and more popular in our work and life. In various electronic products, the humanity cable is widely used as a means of signal transmission, body/body, and has the advantages of flexible transmission and high signal transmission capability. Therefore, it is widely used in many electronic products. In the middle, the flexible cable is used in conjunction with the electrical connector to transmit the signal from one end to the other to achieve the purpose of signal transmission. The structure of a general flexible cable includes a lower insulating layer, a plurality of parallel-arranged metal wires, and an upper insulating layer. wherein the metal wires are connected to the cable connector for convenience, the metal wires are subjected to a process step such as calendering. Forming a wearable structure of the metal wire into a flat rectangular shape, the thin rectangular wearing structure can facilitate the bonding of the flexible cable to the conductive terminal of the cable connector. However, the elongated rectangular surface is worn. The metal wire of the structure has a large lateral width, so that when it is pressed between the upper insulating layer and the lower insulating layer, the soft wire which makes the spacing between the metal wires smaller than each other is disadvantageous for subsequent The cutting is divided into M420803 work, which makes it difficult to make the flexible cable to be folded, wound or jumped, which leads to a decrease in production yield. [New content] The width of the metal wires of the conventional flexible cable is large, so that the distance between the metal wires becomes small, so that it is easy to cause a problem that the production yield is lowered due to the work of cutting and slitting. The present invention provides a flexible flat cable comprising a lower insulating layer, an upper insulating layer and a plurality of metal wires, the upper insulating layer is disposed on the lower insulating layer, and the plurality of metal wires are arranged in parallel in the upper insulating layer and the lower insulating layer. Between the layers, each of the metal wires includes an upper surface, a lower surface, a left side surface and a right side surface, and the upper surface, the lower surface, the left side surface and the right side surface form a metal wire outer surface, the upper surface and the lower surface The surface is in a planar shape, and the left side surface and the right side surface are respectively connected to the left side and the right side of the upper surface and the lower surface, and the maximum distance between the left side surface and the right side surface forms a first width, and the metal wire ends are exposed to the upper insulation. The layer is rolled to form a plurality of contact faces, each contact mask having a second width, the second width being greater than the first width. The flexible flat cable provided by the present invention is designed such that the outer shape of the metal wire has a first width, the end contact surface has a second width, and the second width is larger than the first width. The distance between the metal wires can be increased, which is beneficial to the subsequent processing of the cutting and slitting. Compared with the conventional flexible cable, the flexible flat cable provided by the 4th creation can solve the problem that the distance between the metal wires is small (four) the strips are not easy to be reduced and the profit rate is reduced. [Embodiment] - Moonlight ... from the third to the fifth figure, the present invention provides a winding flat cable 'This type of flat type includes - τ insulating layer 2, a plurality of metal wires 3 and an upper insulating layer 4 . The upper insulating layer 4 is disposed on the lower insulating layer 2, and the plurality of metal wires 3 are arranged in a flat arrangement between the upper insulating layer 4 and the lower insulating layer 2, wherein each of the metal wires 3 includes an upper surface 3 and a lower surface 32. a left side surface 33 and a right side surface 34, the upper surface 31, the lower surface, the left side surface 33 and the right side surface 34 form a metal wire 3. The upper surface 31 and the lower surface 32 are planar and vertically parallel. The left side surface 33 and the right side surface 34 are arranged in a planar shape and are disposed symmetrically in a left-right direction. The left side surface 33 and the right side surface 34 are respectively connected to the left and right sides of the upper surface 31 and the lower surface 32, and the left side surface 33 and the right side surface are respectively connected. The maximum distance between the faces 34 forms a first width 35. The ends of the metal wires 3 are exposed to the upper insulating layer 4 and are calendered to form a plurality of contact faces 36, each contact face 36 having a second width 38 and a second width. 38 is greater than the first width 35. In the present embodiment, the height Η between the upper surface 31 and the lower surface 32 is greater than the width W of the upper surface 31. However, the height Η between the upper surface 31 and the lower surface 32 may be equal to the upper surface 31. The width W' can be advantageously increased by the size of the M420803 between the metal wires 3 to facilitate subsequent processing such as cutting and slitting, since the upper surface 31 and the lower surface 32 are vertically symmetrically arranged in this embodiment. Thus, the width W of the upper surface 31 is substantially equal to the width (not labeled) of the lower surface 32, while the width of the left side surface 33 is substantially equal to the width of the right side surface 34. In this embodiment, the ends of the metal wires 3 are exposed to the upper insulating layer 4 and are rolled to form a plurality of contact faces 36. The ends of the metal wires 3 are exposed to the lower insulating layer 2 and are rolled to form a plurality of opposite faces 37, each of which is formed. The contact surface 36 and the opposite surface 37 with respect to the contact surface 36 are vertically opposed to each other and are open and closed. However, the invention is not limited thereto. Alternatively, as shown in FIG. 6, the metal wires 3 may be disposed on the lower insulating layer 2 and covered by the lower insulating layer 2, only above the contact surface 36. Hollow state. It is worth mentioning that, in this embodiment, a deformation zone 39 is formed between the contact surface 36 and the end of the upper insulating layer 4. The contact surface 36 has a long rectangular shape, and the deformation zone 39 has a trapezoidal shape, and the width of the trapezoidal upper bottom is wide. Equal to the first width 35, the width of the trapezoidal lower base is equal to the second width 38. In addition, the second width 38 is sized to be at least three times larger than the first width 35, and the spacing between adjacent two metal wires 3 is greater than the width of the second width 38 to facilitate subsequent cutting and striping operations. Referring to Figures 7 to 8, the present invention provides another flexible flat cable 5 comprising a lower insulating layer 6, a plurality of metal wires 7 and an upper insulating layer 8. 6 The metal wire 7 of the flexible flat cable 5 also includes an upper surface 71, a lower surface 72, a left side surface 73 and a right side surface 74. The upper surface 71 and the lower surface 72 are planar and up and down. Parallelly oppositely disposed, the left side surface 73 and the right side surface 74 are in the form of a circular arc surface and are disposed symmetrically opposite to each other. The width w of the upper surface 71 is substantially equal to the width of the lower surface 72, and the arc length of the left side surface 73 is substantially equal to The arc length of the right side 74. Similarly, the height Η between the upper surface 71 and the lower surface 72 is greater than the width w of the upper surface 71 or the lower surface 72. It can be understood that the arc length of the left side surface 73 or the right side surface 74 is greater than the upper surface 71 distance. The height η between the surfaces π. The difference between the flexible flat cable 5 and the flexible flat cable 前述 described above is that the left side surface 73 and the right side surface 74 of the metal wire 7 are in a circular arc shape rather than a planar shape, and the remaining structural portions are as follows. The first width 75 formed by the maximum distance between the left side surface 73 and the right side surface 74 is also smaller than the second width 78 exposed to the contact surface 76 of the upper insulating layer 8, and therefore will not be described herein. In summary, the flexible flat line of the present invention utilizes the change of the outer shape of the metal wire to make it the first wide product in the middle section, the end contact surface having the second width and the second width being larger than the first width ^ structure. The shape 'in this way can increase the spacing of the metal wires from each other, which is beneficial to the subsequent cutting operation of the cutting strips. Compared with the conventional soft cable, the flexible flat cable provided by this creation can solve the problem of (4) the distance between the metal wires (4) and (4) the reduction of the material content of the material (9) for the extraction - although it is feasible to implement ^ (4) The examples are not intended to be used in the creation of the application. Any changes and modifications that are not included in the spirit of the art disclosed in this work should be included in the scope of the patents covered by this creation.
