Detailed Description
For a sufficient understanding of the present invention, the present invention will now be described in further detail by referring to the following specific embodiments in conjunction with the accompanying drawings. The objects, features and functions of the present invention will be apparent to those skilled in the art from the disclosure of the present specification. It is to be noted that the present invention may be implemented or applied in other specific embodiments, and various modifications and changes may be made in the details of the present description based on different viewpoints and applications without departing from the spirit of the present invention. The following embodiments will further explain the related art of the present invention in detail, but the disclosure is not intended to limit the scope of the claims of the present invention. The description is as follows:
as shown in fig. 1 and fig. 2, a flexible flat cable 100 according to an embodiment of the present invention includes: a plurality of conductive lines 1, an upper insulating layer 2, and a lower insulating layer 3.
The plurality of wires 1 are arranged in parallel with each other. The lead 1 is a conductor, and may be a copper wire, a silver wire, or other metal and alloy, preferably a material with good conductivity and ductility. In the present embodiment, the wire 1 is a tin-plated pure copper wire, however, the present invention is not limited thereto.
The upper insulating layer 2 and the lower insulating layer 3 sandwich the conductive wire 1. The upper insulating layer 2 and the lower insulating layer 3 are insulators, and may be collectively referred to as a dielectric layer or an insulating outer layer. The upper insulating layer 2 and the lower insulating layer 3 can be made of any insulating and flexible material, such as insulating plastic.
As shown in fig. 2, the upper insulating layer 2 and the lower insulating layer 3 are provided with a plurality of drilled holes 4, respectively. Since air has a dielectric constant lower than that of a general insulating material, providing a plurality of holes 4 can change the overall equivalent electrical effect of the upper insulating layer 2 and the lower insulating layer 3, improve the quality of the high-frequency signal transmitted by the wire 1, and improve the transmission speed.
Further, in the present embodiment, as shown in fig. 2, the bore 4 penetrates through the upper insulating layer 2 or the lower insulating layer 3. However, the present invention is not limited thereto, and the drilled hole 4 may be a non-through recessed hole.
Further, in the present embodiment, the plurality of bores 4 are arranged equidistantly from each other. However, the present invention is not limited thereto, and the drill holes 4 may be arranged at different distances, for example, densely arranged at a specific position.
Further, in the present embodiment, the plurality of bores 4 are all the same size. However, the present invention is not limited thereto, and each of the drill holes 4 may be a hole having a different aperture.
Further, in the present embodiment, as shown in fig. 2, a shielding layer 6 is further included. The shielding layer 6 covers the outer sides of the upper insulating layer 2 and the lower insulating layer 3. The shielding layer 6 may be made of non-magnetic material such as copper, aluminum, etc. to prevent external electromagnetic waves from interfering with the signal transmission of the wire 1.
The present invention has been disclosed in the foregoing in terms of embodiments, but it will be understood by those skilled in the art that the embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of the invention. It should be noted that all changes and substitutions equivalent to the embodiments are intended to be included within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
