The flexible Flat Cable is called as Flexeble Flat Cable for short FFC. The novel data cable is formed by laminating a PET (polyethylene terephthalate) insulating material and an extremely thin tinned flat copper wire through a high-tech automatic equipment production line, and has the advantages of softness, random bending and folding, thin thickness, small volume, simplicity in connection, convenience in disassembly, easiness in solving of electromagnetic shielding (EMI) and the like. The number and the spacing of the wires can be selected at will, so that the connection is more convenient, the size of an electronic product is greatly reduced, the production cost is reduced, the production efficiency is improved, and the wire is most suitable for being used as a data transmission cable between a mobile part and a main board, between a PCB and the PCB and in miniaturized electrical equipment.

Electromagnetic interference emi (electromagnetic interference) includes both conducted interference and radiated interference. Conducted interference refers to coupling (interfering) a signal on one electrical network to another electrical network through a conductive medium. Radiated interference refers to interference sources coupling (interfering) their signals through space to another electrical network. In the design of high-speed PCB and system, high-frequency signal lines, pins of integrated circuit, various connectors and the like can become radiation interference sources with antenna characteristics, and can emit electromagnetic waves and influence the normal work of other systems or other subsystems in the system.

In order to reduce electromagnetic interference, some electronic products utilize a grounding technology to eliminate the electromagnetic interference, but at present, a transmission line used for a grounding circuit board generates the electromagnetic interference in the transmission process, the transmission efficiency is higher, the interference is smaller, but a wire taken as the existing transmission line is arranged in two layers of insulating films, the loss is larger in transmission, and therefore the transmission efficiency is low, and the interference is larger.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a rational in infrastructure simple, the practicality is strong, and the transmission energy consumption is little, produces the little transmission line of being applied to ground circuit board of electromagnetic interference.

In order to achieve the above purpose, the utility model provides a following technical scheme:

a transmission line applied to a grounding circuit board comprises an upper layer insulating film and a plurality of conductors

Detailed Description

Embodiments of the present invention are further described with reference to fig. 1 to 2.

The embodiment has the specific structure that: including upper insulating involucra 1, plural root wire 3, lower floor's insulating involucra 2 and stiffening plate 4, plural root wire 3 is parallel to be set up side by side, and upper surface and the laminating of upper insulating involucra 1 mutually, the laminating of lower surface and lower floor's insulating involucra 2 mutually.

Its epidermis is rejected on 1 surface of upper insulating involucra, and it has a plurality of square pieces 11 to constitute, and wire 3 in the square piece 11 is visible outward, and the distance between two adjacent square pieces 11 equals, and the quantity that stiffening plate 4 corresponds square piece 11 is pasted and is established on the surface of lower floor's insulating involucra 2, and the outer wire 31 that sets up according to its length still is rejected on 1 surface of upper insulating involucra, and outer wire 31 is visible outward.

The arrangement of the plurality of exposed visible lead 3 areas reduces the energy consumption in the transmission process with the grounding circuit board, improves the transmission efficiency, and further reduces the electromagnetic interference, particularly, the arrangement of the exposed outer lead 31 enables the lead 3 in each square block 11 to be quickly conducted, and reduces the electromagnetic interference.

The outer conductor 31 is the third up to down conductor 3. The third conductor 3 is used as the outer conductor 31 for convenience of molding.

When the distance between two adjacent square blocks 11 is 35mm, the generated energy consumption ratio is relatively low and high.

If the ratio of the length of the reinforcing plate 4 to the length of the square block 11 is greater than 1.2-1.4, the reinforcing plate 4 is too long, and the energy consumption ratio and the production cost are increased.

If the ratio of the length of the reinforcing plate 4 to the length of the square block 11 is less than 1.2-1.4, the reinforcing plate 4 is too short, so that the wire 3 in the square block 11 cannot be supported, and the square block 11 is easily deformed, thereby affecting the transmission efficiency.

In summary, when the ratio of the length of the reinforcing plate 4 to the length of the square 11 is 1.2-1.4, the reinforcing plate 4 can support the square 11 most effectively. The optimal ratio for this example is 1.3.

The distances from the two ends of the square block 11 to the two ends of the reinforcing plate 4 are equal. The middle position of the reinforcing plate 4 is arranged in the square plate, and the wire 3 in the square block 11 is well protected.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and the skilled in the art can carry out the common changes and replacements within the technical solution of the present invention.
