Embodiment

[0053] Hereinafter, embodiments of the flexible flat cable of the present invention will be specifically described.

[0054] The ingredients shown in Table 1 were used as raw materials of the resin composition, and the materials shown in Table 1 were kneaded using a twin-screw kneading extruder or a kneader to obtain the mixing amounts shown in Tables 2 to 4 ( parts by weight), thereby obtaining 12 kinds of resin compositions.

[0062]

[0063] Next, flexible flat cables were produced by extrusion using 12 kinds of resin compositions ( figure 1 model of the section shown). Specifically, six right-angle conductors made of electrical copper having a width Wo of 2.0 mm and a thickness To of 0.15 mm, six right-angle conductors having a width Wo of 2.0 mm and a thickness To of 0.10 mm, or having a width of 2.0 mm Six right-angle conductors of Wo and thickness To ...

Abstract

Provided are a method of manufacturing a flexible flat cable in which a thin flexible flat cable required for use of a narrow cable routing space for automobiles and the like is stably obtained, and a flexible flat cable having higher flexibility than a product in the related art due to the decrease in the thickness. A flexible flat cable configured to have an insulating layer disposed through extrusion in vicinities of a plurality of conductors arrayed in parallel with each other, in which the insulating layer is composed of a vinyl chloride-based resin composition having a die swell ratio of 1.1 or more at a molding temperature during the extrusion.

Description

technical field [0001] The present invention relates to a flexible flat cable, and in particular, to a flexible flat cable manufactured by extrusion. Background technique [0002] A flexible flat cable is used for electrical connection such as a moving part and a fixed part due to its flexibility, is very flexible in shape, requires only a small space, and can be easily wound as needed. Due to the advantages described above, the flexible flat cable has an extremely wide range of use, such as connection between a scanning head, a printer head, etc., and a main body portion as a fixed portion, and a clock spring in an automobile. [0003] Such flexible flat cables are often manufactured using lamination methods. Such methods include the technique proposed in JP-A-10-278206. That is, this technique is a technique of laminating conductors using a composite sheet manufactured by laminating a heat-sealing layer composed of a heat-sealing resin on a base plate composed of a satur...
