Description

Technical Field

[0001] The utility model relates to the technical field of dustproof FFC cable, in particular to a dustproof FFC cable. Background Art

[0002] FFC cable, also known as flexible flat cable, can arbitrarily select the number and spacing of wires, making wiring more convenient, greatly reducing the size of electronic products, reducing production costs, and improving production efficiency. It is most suitable for use as data transmission cables between mobile parts and motherboards, between PCB boards, and in miniaturized electrical equipment.

[0003] After searching, a Chinese patent with publication number CN215911700U discloses an FFC cable, and its technical key points are: the utility model discloses an FFC cable, which relates to the field of FFC cables, including an upper insulating layer, a copper wire fixing layer is fixedly connected to the lower surface of the upper insulating layer, a lower insulating layer is fixedly connected to the lower surface of the copper wire fixing layer, a heat dissipation layer is fixedly connected to the lower surface of the lower insulating layer, a splicing layer is fixedly connected to the lower surface of the heat dissipation layer, and a plurality of metal wires are fixedly connected and connected transversely inside the copper wire fixing layer, a first turning wire is fixedly connected to both ends of the metal wire, a vertical bare wire is fixedly connected to the bottom of the first turning wire, a second turning wire is fixedly connected to the bottom of the vertical bare wire, a horizontal bare wire is fixedly connected to the end of the second turning wire away from the vertical bare wire, an arc plate is abutted on the upper surface of the horizontal bare wire, a reinforcing plate is fixedly connected to the middle of the top of the arc plate, and the first turning wire is bent at ninety degrees. The utility model provides a large contact surface for welding by setting the first turning wire, the second turning wire and the horizontal bare wire, thereby ensuring a firm welding.

[0004] The above solution solves the problem that the structure of the bare wire end of the existing FFC cable mostly only allows the end of the bare wire end to be welded to the external interface, which is prone to loose welding. At the same time, the bare wire end is easy to deform and cannot be aligned with the interface to be welded, affecting the welding work and effect. However, this device cannot prevent dust from the FFC cable. Dust is easily accumulated on the FFC cable during use. Long-term accumulation of dust is likely to cause poor contact of the wires, affecting use and increasing the process of cleaning dust.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the above background technology, the prior art has the problem that the FFC cable cannot be dust-proofed.
