Embodiment Construction

Embodiments of the flexible flat cable of the present invention will be described below based on experimental results.

[0039] The inventors of the present application use the above-mentioned conductor 11, the first insulating material 12 and the second insulating material 13, the first non-woven fabric 14 and the second non-woven fabric 15, the first 1 ground foil 18 and second ground foil 19 and first shielding material 23 and second shielding material 24 as Figure 5 flex flat cable shown.

[0040] [Table 1]

[0041] [Table 2]

[0042] Specifically, according to the specifications shown in the above-mentioned Table 1, the flexible flat cable produced in the first embodiment uses a non-woven fabric having a flame retardant impregnated with cellulose as the first non-woven fabric 14 and the second non-woven fabric. Spinning15. In addition, according to the specifications shown in the above-mentioned Table 2, the configuration of the flexible flat cable manufac...

Abstract

Provided is a thin flexible flat cable which can exhibit an excellent flexibility and bending resistance without degrading excellent electric characteristic based on a strip structure and improve thecost performance. The flexible flat cable (1) includes: an air-containing layer which has a width substantially identical to a transmission path width of a cable body (10) having a plurality of conductors (11) arranged at a predetermined pitch and which serves as an insulating member arranged to sandwich the cable body (10) from both sides; and a shield member (23, 24) which covers the surface ofthe air-containing layer and is electrically connected to a ground layer at terminal portions at both ends of the cable body (10). The air-containing layer is formed by nonwoven fabric pieces (14, 15)cut with a width substantially identical to the transmission path width of the cable body (10).

Description

technical field [0001] The present invention relates to a flat cable used as a transmission cable for various parts equipped inside various electronic equipment products. Background technique [0002] Conventionally, in various electronic products such as PCs, flat-screen TVs, printers, and scanners, flat cables have been widely used as relay cables for various internal components. When it comes to flat cables, they are generally products obtained by etching flexible printed circuits. While the cost is high, due to the influence of the production line conditions, the length of the cables produced at this stage can only be less than 1000mm. Therefore, it is difficult to adapt to thin TVs that continue to expand in size. [0003] Therefore, a flexible flat cable manufactured using a so-called rolling method has attracted attention as a substitute for a flexible printed circuit type flat cable. Due to its superior flexibility, the flexible flat cable can be used in movable pa...
