AI Technical Summary
Existing FFC products are prone to conductor breakage after multiple bending, resulting in circuit disconnection.
By increasing the number of conductor layers on the structure of existing FFC products, a multi-layer conductor structure is formed to ensure that the circuit can remain conductive even if part of the conductor is broken.
This enhances the FFC product's resistance to conductor bending and breakage, ensuring that the circuit remains conductive even after multiple bends.

[0002] Soft cable (Flexible Flat Cable, hereinafter referred to as FFC) is made into a whole by hot-pressing film 1' and single-layer conductor 2' together through calender, and the cross section of the present FFC product is as shown in the figure Figure 1 The existing product is single-layer conductor, and conductor fracture occurs after multiple bending, so that the circuit is not conductive. SUMMARY
[0003] The utility model aims at providing a FFC multilayer conductor structure to solve at least one of the above problems in the prior art.
[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:
[0005] A FFC multilayer conductor structure comprises a first film, a second film and a multilayer conductor, and the multilayer conductor is hot-pressed and attached between the first film and the second film.
[0006] In the structure of the existing FFC product, the number of layers of the conductor is increased to form a multilayer conductor on a single circuit conductor, and the thickness of the multilayer conductor can remain unchanged or increase. Even if the conductor is fractured after multiple bending of the multilayer conductor, as long as one layer of the conductor is complete, the circuit can still conduct electricity. Even if all the multilayer conductors are fractured, as long as the fracture positions do not all coincide, the corresponding circuit can still be conductive. The technical scheme increases the risk resistance of the FFC series product to conductor bending fracture.
[0007] Further, in order to provide a conductor structure, the multilayer conductor comprises a first conductor and a second conductor attached in an upper and lower manner.
[0008] Further, in order to provide another multilayer conductor structure, the multilayer conductor comprises a first conductor, a second conductor and a third conductor attached in sequence.
[0009] The utility model has the beneficial effects that: in the structure of the existing FFC product, the number of layers of the conductor is increased to form a multilayer conductor on a single circuit conductor, and the thickness of the multilayer conductor can remain unchanged or increase. Even if the conductor is fractured after multiple bending of the multilayer conductor, as long as one layer of the conductor is complete, the circuit can still conduct electricity. Even if all the multilayer conductors are fractured, as long as the fracture positions do not all coincide, the corresponding circuit can still be conductive. The technical scheme increases the risk resistance of the FFC series product to conductor bending fracture. BRIEF DESCRIPTION OF DRAWINGS
