New Description: [New Technology Field] This creation is about a flexible flat cable, especially for a flexible flat cable that can reduce the width. [Prior Art] According to 'Flexible Flat Cable' (Flexible Flat Cable), referred to as flexible cable or FFC, is a kind of PET insulation material and very thin tinned flat copper wire through the high-tech automation equipment production line Data cable. The flexible cable is a component for signal transmission, and has the advantages of arbitrarily flexing and high signal transmission capability, and is widely used in many electronic products. ^ The general flexible cable is subdivided into a three-layer structure, which is a stacking method of the upper insulating layer, the wiring layer and the lower insulating layer from top to bottom. The plurality of flat copper wires in the wire layer are separated from each other and partially exposed. The two ends of the flexible cable 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 electrically contacted with one of the systems, and the receiving point is received by each guiding point. The signal is transmitted to the corresponding guiding point on the other end of the flexible cable and transmitted to another system for 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 design of mobile electronic devices. Therefore, it is necessary to reduce the lateral width dimension of the flexible cable, and the wire layer of the __ __ is composed of a plurality of parallel-lined tin-plated copper wires, so the lateral width of the wire is necessary - (4) The distance of the distance, when the soft cable is to be assembled in the small cypress narrow and long space (four), because the lateral width of the (four) sex cable can not be properly bent, so it will often produce a smooth and flexible cable. The problem of the small-footed narrow green Γ [New content] The horizontal width of the conventional soft cable is necessary to have a __ fixed distance size' because the horizontal width of the flexible cable cannot be appropriately reduced and reduced. Frequently, there is a problem that the flexible cable cannot be smoothly inserted into a narrow space of a small size. The present invention provides a flexible flat cable comprising: a flexible cable and a plurality of strips, wherein the flexible cable is composed of a plurality of circular wires arranged in parallel and an insulating layer covering the circular wires. The _-shaped wire has a circular cross section, and each end of the round wire has a flat guiding surface exposed on the insulating layer. The plurality of strips are cut by a plurality of slits along the axial direction of the circular wires to form 'the slits are located between any two round wires, and the plurality of strips in the pot have a plurality of strips Folded, the splicing materials are parallel to each other, and the width of the folded portions as a whole is smaller than that of the soft splicing line. The tying type wire gauge is bent by the cutter at the soft strip portion f: 77, called In the case of a plurality of strips, the length of the strip is two = stack structure, and the degree of solution can be smoothly and effectively reduced due to the structure of the fold, so that the empty block can not be smoothly inserted into the small size. The narrow and long cut is made as a chapter = material 'soft line with 81-shaped wire is in progress:: industry time, due to the large spacing between adjacent two circular wires, it can be & Rate, such as reducing the production cost. [Embodiment] Referring to the first figure, the flexible flat wire winding 1 of the present invention includes a flexible cable 2 and a plurality of recording strips 3, wherein the shaft strip portion 3 is provided a plurality of folded portions 31, the folded portions 31 are overlapped with each other in parallel, and the folded portions 31 are The width W1 is smaller than the width W2 of the hard-to-wire line f. ', for the convenience of explaining the structure of the flexible flat cable 本 of this creation, please refer to the second figure to the fifth figure, which is the first figure. The flexible cable 2 of the flexible flat cable 1 has not been cut into the original structure of the plurality of strips 3, a partial exploded view, a partially enlarged view, and a partial cross-sectional view. The line 2 is composed of a plurality of circular wires η arranged in parallel and an insulating layer 22 covering the circular wires 21, the circular wires 21 having a circular cross section 23, each of the circular wires 21 The end has a flat guiding surface 24 exposed on the insulating layer 22. The insulating layer 22 M419202 is composed of an upper insulating layer 221 and a lower insulating layer 222, and is disposed on the upper surface of the insulating layer 221 above the flexible wiring 2. An upper metal layer (not shown) is disposed on the lower surface of the insulating layer 222 under the flexible wiring 2, so that a better electromagnetic wave interference prevention effect can be obtained. The width D1 of the flat guiding surface 24 is greater than the diameter D of the circular section 23 2 size, so as to facilitate the connection of the flexible flat cable 1 and the mating connector (not shown). The reinforcing plate 4 is disposed at one end of the flexible cable 2, wherein the flat guiding surface 24 is disposed at The reinforcing plate 4 is configured to increase the strength when the flat guiding surfaces 24 are butted. Each of the circular wires 21 includes one abutting portion 211 having a flat guiding surface 24 and one body portion 212 having a circular cross section 23. 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 on the insulating layer 22, so that the flat guiding can be smoothly formed during the calendering process of the butting portion 211. In the present embodiment, the underside of the abutting portion 211 and the buffer portion 213 is a hollow state in which the lower insulating layer 222 is not retained. In order to increase the strength at the time of docking, the abutting portion 211 and the buffer portion 213 are disposed on the reinforcing plate. Alternatively, the lower insulating layer 222 may be left under the abutting portion 211 and the buffer portion 213, and the reinforcing plate 4 may be disposed under the lower insulating layer 222. In addition, the second spacing P2 between the adjacent two body portions 212 is greater than the first spacing P1 between the adjacent two abutting portions 211, and the larger second 6 M419202 spacing P2 is advantageous for the subsequent cutting and slitting operations to be reduced. Process yields due to poor cutting are reduced. Please refer to the sixth figure and the first figure, which is a schematic view of the flexible cable 2 of the flexible flat cable 1 which is cut into a plurality of secret parts 3 and a top view after being bent and folded. . The flexible cable 2 is cut into a plurality of strips 3 along the axial direction of the circular wires 21 by a plurality of slits 3, and each of the slits 30 is located on any two circular wires 21 In the present embodiment, the towel-per-long strip portion 3 includes four circular wires 2, but is not limited thereto, and may be designed to include other numbers of round wires 21 'substantially mother-long strip portion 3 The more the number of round wires μ included, the larger the width of the folded portion 31 formed. The female long strip portion 3 has a first fold line 32 and is bent along the first fold line in a first direction to form a folded portion 3. The long strip portion 3 has a second fold line 33 and is bent along the twisted line 33 in the second direction. A fold portion 3 is formed between the first fold line and the second fold line 33. In the present embodiment, the length of the folded portion 31 of each strip portion 3 is close to the axis of the circular wire 21 perpendicular to the flexible cable 2. The direction is not limited to this, and other tilt angles can also be used. The plurality of strips 3 are provided with a plurality of folds 31, and the folds 31 are overlapped with each other in parallel such that the width W1 of the folds can be much smaller than the original width ψ2 of the flexible cable 2, thereby achieving The purpose of reducing the lateral width of the flexible cable 2 is reduced. 7 In the present embodiment, for mosquitoes, (four) or adjusting the electrical impedance: as shown in the seventh figure, a bag of coffins 5 is also provided to surround the two, the portion 31' wherein the wrapping material 5 is an insulating material For example, the vinegar k cloth is not limited thereto, and the wrapping material 5 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. In summary, the flexible flat cable of the present invention uses a cutter to cut a strip on a flexible wire to form a plurality of strips, and then folds the strips to form a folded structure. The folding structure can achieve the purpose of reducing the lateral width of the flexible cable, so that the problem that the conventional flexible cable cannot be smoothly plugged into a small size (four) can be solved. In addition, the flexible cable with round wire, the row knife D'j operation 4, due to the large spacing between adjacent two circular wires', can make the size of the space available to the cutter cutting strip = formation a plurality of strips, and the circular surface of the circular wire facilitates the combination of the heat between the upper insulating layer and the lower insulating layer, so that the production yield is reduced due to poor cutting.
