New description: [New technical field] This creation is about a flexible flat cable structure, especially for a flexible flat cable structure that can prevent damage to the hub. [Prior Art] Flexible Flat Cable, referred to as flexible cable or FFC, is a data cable 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, short, and small direction, in order to accommodate the miniaturization of portable electronic devices, the lateral width of the flexible cable must be reduced in size. Therefore, the manufacturer has developed a cable structure as shown in the first figure, which uses a cutter to cut the middle section of the split flexible cable 1 to form a plurality of split lines 11, which are bent and overlapped in parallel to form Since the line portion 12 can reduce the original lateral width W1 of the flexible cable 1 to W2, the conventional softness can be solved, and the problem that the line cannot be crowded into a small size space can be solved. The line portion 12 formed by the dividing line 11 of the dividing line I must be fixed to prevent the line points 11 fc from being dissipated. A conventional method is wound around the line portion 12 by the tape 2 . To achieve the purpose of timeline 11. Therefore, the flexible cable 1 having the concentrating portion 12 can solve the problem that the S-force flexible cable can not be used for small size space, but the concentrating portion 12 is generally assembled in a hinge or a hinge. In the slender accommodating space, when the frame is subjected to the repeated switch sway test, the occlusion portion 12 is usually subjected to the influence of the repeated action of the torsion and is likely to cause partial line breakage 11 damage, thus causing the customer to sue. The problem arises. [New content] The soft cable of the S U line does not have the structure of the buffer protection line. Therefore, when the line part is subjected to the influence of the repeated action of the torque, it is easy to cause partial line damage, which leads to the problem of the lawsuit. This creation provides a type of secret structure, including - a flexible line and at least a cladding layer, the t flexible line has a buffer between the two sets of lines and the green part of the set, each of the line parts is A plurality of bars = formed by overlapping each other in parallel. The cladding layer surrounds the two hub portions, and the cladding layer covers the plurality of branch lines of each of the cluster portions. The flexible flat line county structure provided by this creation deliberately splits the secret part of H into two line parts, and adds a buffer part between the two sets of M443918 to use this buffer part to achieve buffering. The influence of the large torsion effect of the original strip line part can solve the problem that the prior art is prone to partial line damage, so as to avoid the problem of customer complaints. [Embodiment] Please refer to the second and third figures. The flexible flat cable structure of the present invention is respectively cut through a dividing line and bent and folded. The flexible flat cable structure comprises a flexible cable 3, which is composed of a plurality of metal wires 31 arranged in parallel and an insulating layer 32 covering the metal wires 31, wherein the insulating layer 32 comprises the metal layer. An insulating layer 321 and a lower insulating layer 322 are disposed on the upper surface of the upper surface of the wire 31. The flexible cable 3 is extended along the axial direction of the metal wire 31 by a plurality of slits 30 to cut the flexible cable 3 into a plurality of lines. The first dividing line 33 and the plurality of second dividing lines 34 form a buffer portion 35 between the plurality of first dividing lines 33 and the second dividing line 34. The first and second partial lines 33, 34 include a plurality of metal wires 31, and the metal wires 31 are divided into a signal line and a ground line according to a function definition. The plurality of first partial lines 33 and the second partial lines 34 are respectively superposed in parallel to each other to form a first line portion 36 and a second line portion 37. The buffer portion 35 is disposed at the first line portion 36 and the second line portion 37. between. In this embodiment, the buffer portion 35 is a non-separation region in which no branch line is disposed, and the first hub portion 36 and the second hub portion 37 are respectively provided with 5 M443918 having a plurality of first branch lines 33 and The split line area of the dichotomy line 34. However, the buffer portion 35 may be a branch line region in which the first branch line 33 or the second branch line 34 is provided, but the buffer portion 35 is a non-separated area. The effect is good and the automatic bending and folding process is easy. In this embodiment, the first line portion 36 is formed by stacking a plurality of first line 33s, and the second line portion 37 is formed by stacking a plurality of second lines 34 on each other, each of the first lines. The width of 33 is equal to the width of each second branch line 34, and the height of the first line portion 36 is equal to the height of the second line portion 37, which is like deliberately separating the length of the original single strip. The two shorter lengths of the line portion are then provided with a buffer portion 35 between the two line portions, and the buffer portion 35 is used to buffer the influence of the large torsion of the original single line portion, thereby solving the problem. Conventional technology is prone to the problem of partial line damage, in order to avoid the problem of customer complaints. However, the other is that, as shown in the fourth figure, the width of each of the first partial lines 33 may not be equal to the width of each of the second partial lines 34, such that the height of the first line portion 36 is not equal to The height of the second line portion 37 is used to match the height and width of the space design of the product. At this time, the buffer portion 35 functions as a first branch line 33 and a second branch line 34 which separate the two different widths in addition to the effect of the buffering torque. The cladding layer 4 surrounds the first and second line portions 36 and 37, wherein the cladding layer 4 is used to cover and fix the first and second lines of the first and second current lines 6 and 36. 33, 34, to avoid the first, the second line 33, 34 loose and scattered. In this embodiment, the cladding layer 4 includes a first cladding layer 41 and a second cladding layer 42. The first package covers and fixes the first line portion 36, and the second cladding layer (10) = Fixing the second hub portion 37<) can be understood that it can be additionally increased by two! a coating layer (not shown) of the third cladding layer simultaneously: covering the first cladding layer and the second cladding layer to form the first and second collecting portions 36, 37 and Buffer portion 3; fixed body. However, the present invention is not limited to this. Alternatively, the first line portion % and the buffer portion % first line portion 37 may be coated and fixed at the same time with only one package::4, so that the first and second line portions are %, The π and the buffer portion 35 are fixed, that is, the cladding layer 4 can replace the first cladding layer 4 - the combination of the second cladding layer 42 and the third cladding layer. In the present embodiment, the 'the first and second line portions 36 and 37 are respectively formed on the two sides of the buffer portion 35. The first line portion 36 is bent to the left with respect to the buffer portion 35. The second line portion 37 is opposed to the second line portion 37. The buffer portion is bent to the right, and the longitudinal direction of the first and second collecting portions 36, 37 and the width direction of the buffer portion 35 are parallel to each other, that is, the first and second collecting portions 36, 37 are opposed to the buffer portion. 35 bends 9 degrees. In addition, the flexible cable 3 has a front-side plug end 38 and a rear plug-in end (10), and a first hub portion 36, a buffer portion 35 and a first portion are formed between the front plug-in end 38 and the rear plug-in end 39. The second collecting portion 37, the first and second collecting portions 36, 37 are close to the side of the buffer portion 35 except that the third system is separated from each other, and the other is that the first and second collecting lines can also be used. The portions 36, 37 are stacked on each other close to one side of the buffer portion 35. It is worth mentioning that the spacing between the metal wires 31 is reduced to less than the width of the metal wires 31 due to the effect of the reduction. Therefore, the cutting seams 30 can be directly disposed in the metal wires 31. On the grounding line, the problem of the drop rate of the cutting line of the prior art can be effectively solved. In this embodiment, the cladding layer 4 is a conductive cloth, and the conductive cloth surrounds the ground lines of the first and second partial lines 33 and 34 when surrounding the first and second collecting portions 36, 37. The electrical conduction is formed, so that the purpose of preventing electromagnetic interference (EMI) can be achieved. In addition, a connector connector (not shown) may be additionally disposed at the plug end 38 or the rear plug end 39 before the flexible cable 3, the connector connector includes a lower housing and an upper housing, and the flexible cable 3 The ends of the metal wires 31 are exposed on the insulating layer 32 to form a plurality of conductive contacts. The ends of the flexible wires 3 are interposed between the lower case and the upper case and expose the conductive contacts to form a line end connection. Device. In summary, the flexible flat cable structure of the present invention deliberately splits the original single line portion into two collecting portions, and adds a buffer portion between the two collecting portions, and uses the buffer portion to achieve buffering. The influence of the large torsion effect of the original strip line part can solve the problem that the prior art is prone to partial line damage, so as to avoid the problem of customer complaints.
