New Description: [New Technology Field] [0001] This paper is about a flexible flat cable, especially a flexible flat cable with better characteristic impedance. [Prior Art] [0002] Chinese Patent Application No. 20041 0004696. No. 1 discloses a flexible flat cable which has been widely used as an LVDS signal line in a liquid crystal display (LCD Monitor). The impedance is between 85 and 115 Ω. However, the current flexible flat cable has been widely used as an LVDS signal line for LCD TVs, notebooks, printers, "Scanners", etc. For electronic devices: characteristic impedance; to: not exactly the same, so a flexible flat cable with a characteristic impedance between 85-115 Ω may not be applicable to the above various electronic devices. [0003] Therefore, there is a need for an improved flexible sea level _^ with the above-mentioned drawbacks of the prior art. ...' [New Content] " [0004] The main purpose of this creation is to provide a flexible flat cable that adjusts and controls the characteristic impedance through its own structure. [0005] The purpose of the present invention is achieved by the following technical solution: a flexible flat cable comprising: a plurality of transversely parallel spaced conductors and an insulator covering the plurality of conductors, the upper surface of the insulator being provided with a defect The portion of the plurality of conductors in the longitudinal direction is exposed on the upper surface of the insulator, and the flexible flat cable further includes a first form number formed on the upper surface of the insulator Α0101, page 3/10 pages, M413201, an insulating layer, and a second The insulating layer and the metal layer, the first and second insulating layers and the metal layer are sequentially arranged from the inside to the outside, and the material of the first insulating layer is different from the material of the second insulating layer. [0006] Compared with the prior art, the present invention has the following effects: without adjusting the shielding rate of the silver paste, the characteristic impedance of the flexible flat cable is realized by using two insulating layers of different materials, thereby making the flexible flat cable easy to manufacture. . [Embodiment] [0007] Referring to the first to third figures, the flexible flat cable 1 of the present invention includes a plurality of conductors 21 arranged in parallel horizontally spaced apart and an insulator 22 coated on the outside of the plurality of conductors 21. The upper surface 221 of the flexible flat cable 1 insulator 22 is provided with a missing portion 222 such that a portion of the plurality of conductors 21 in the longitudinal direction is entirely exposed on the upper surface of the insulator 22, and the plurality of conductors 21 are on the right side of the base. The insulator 22 is covered. The lower surface 223 of the flexible flat cable 2 insulator 22 is provided with a missing portion 224 for exposing a portion of the plurality of conductors 21 in the longitudinal direction to the lower surface 223 of the insulator 22, and the left free end of the plurality of conductors 21 is also covered by the insulator 22. cover. The two missing portions 222, 224 of the insulator 22 are respectively close to the two free ends of the flexible flat wire 2: [0008] Referring to the third figure, the upper and lower surfaces 221, 223 of the flexible flat cable 1 are respectively The first insulating layer 23, the second insulating layer 24 and a layer of silver paste 25 are sequentially attached inside and outside, and the materials of the two insulating layers 23, 24 are different, and each layer of silver paste 25 is respectively applied to the second insulating layer 24. The outer surface. In addition, a transparent varnish 26 is also shielded from the outer surface of each layer of silver poly 25 for protecting the silver paste 25. The material of the two insulating layers 23, 24 may be polyethylene terephthalate (PET), polyimide or polyolefin resin. Form No. A0101 Page 4 of 10 [0009] It should be noted that since the first and second insulating layers 23, 24 on the flexible flat cable 1 use different materials, the design can adjust and control the flexible flat wire. The characteristic impedance of the cable 1 is between 70 Ω and 130 Ω, so that the flexible flat cable 1 can be applied in different electronic devices.
