Summary of the invention
The purpose of this utility model is to provide a kind of flexible flat cable, improves its characteristic impedance controllability and shield effectiveness.
The purpose of this utility model is achieved through the following technical solutions.
A kind of flexible flat cable, comprising: plain conductor, lower floor's insulating coating and high frequency absorbing material layer;
Described lower floor insulating coating fits in the two ends of the lower surface of plain conductor, and described high frequency absorbing material layer fits in the lower surface of plain conductor and its two ends and cover the part outer surface of described lower floor insulating coating.
Wherein, also comprise stiffening plate; Described stiffening plate fits in one end of the lower surface of plain conductor, and between described lower floor insulating coating and high frequency absorbing material layer, between the now length that is shorter in length than lower floor's insulating coating of described stiffening plate, and described lower floor insulating coating, stiffening plate, high frequency absorbing material layer three, be in contact with one another.Or stiffening plate fits in one end of the lower surface of described plain conductor, and be positioned at the skin of lower floor's insulating coating and high frequency absorbing material layer.
Wherein, described plain conductor includes complex root and discharges side by side formation parallel lines structure.
Wherein, also comprise upper strata insulating coating, fit in the upper surface of described plain conductor.
Wherein, the upper surface of one end that is fitted with stiffening plate of described plain conductor is exposed to outside outer, the other end is exposed to completely.
Wherein, described plain conductor is cylindrical metal wire, flat plain conductor or metallic cable.
Wherein, described plain conductor is specially copper cash.
Wherein, described upper strata insulating coating and lower floor's insulating coating are PET material.
Compared with prior art, beneficial effect is the utility model:
The utility model embodiment, by the lower surface laminating high frequency absorbing material layer at plain conductor, has strengthened characteristic impedance controllability and the shield effectiveness of FFC greatly; Simultaneously, between plain conductor and high frequency absorbing material layer, set up one deck insulating coating and stiffening plate, avoid stiffening plate or high frequency absorbing material layer to be directly attached on plain conductor, there will not be and peel off or other anomalies, ensured the stability of product structure.
Brief description of the drawings
Fig. 1 is the structural representation of traditional FFC;
Fig. 2 is the structural representation of FFC in the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to shown in Fig. 2, in the present embodiment, FFC comprises: upper strata insulating coating 21, complex root plain conductor 22, lower floor's insulating coating 23, stiffening plate 24, high frequency absorbing material layer 25.
Complex root plain conductor 22 side by side discharge forms parallel lines structure, its upper surface and upper strata insulating coating 21 fit and two ends exposed, one end of lower surface fit successively lower floor's insulating coating 23 and stiffening plate 24, high frequency absorbing material layer 25 fits in the lower surface of complex root plain conductor 22 and its two ends and covers the part outer surface of stiffening plate 24.
Wherein, upper strata insulating coating 21 and lower floor's insulating coating 23, play the effect of insulating protection.Plain conductor 22, is specifically as follows cylindrical copper, flat copper cash or copper stranded conductor, plays conducting effect.Stiffening plate 24, plaing a part increases terminal intensity, is convenient to FFC and pegs graft, and can adopt common stiffening plate, also can adopt high temperature resistant stiffening plate, and the cost of certain high temperature resistant stiffening plate is higher.High frequency absorbing material layer 25 can be controlled winding displacement characteristic impedance for one, has the high-frequency insulation material of shield effectiveness simultaneously.
Because insulating coating is high temperature resistant, larger with adhesion strength after plain conductor 22 laminatings, can directly be attached to above plain conductor 22; And stiffening plate 24 and high frequency absorbing material layer 25 non-refractory are less with adhesion strength after plain conductor 22 laminatings, should not directly be attached to above plain conductor 22.Lower floor's insulating coating 23 and stiffening plate 24 so the present embodiment is first fitted at the two ends of the lower surface of plain conductor 22, then the high frequency absorbing material layer 25 of fitting, avoid occurring peeling off or other anomalies, ensured the stability of product structure.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
