Description

Flexible flat wire Technical Field The utility model relates to the technical field of electronic wires, in particular to a flexible flat wire. Background In the field of electronic wires, flexible flat wires are widely used in high-precision scenes such as signal transmission in equipment and connection of precise electronic components due to their light, thin and flexible characteristics. The conventional flexible flat wire is usually manufactured by laminating an upper layer of Polyethylene (PE) film and a lower layer of PE film on a metal conductor by a hot press molding process. However, the structure has the corresponding defect in practical application that the stitch (namely PIN) at the front end of the golden finger is easy to warp or deform in the process of transporting or frequently plugging the connector due to the insufficient interface bonding strength of the PE adhesive film and the metal conductor. The mechanical damage not only can cause poor contact of the whole circuit, but also can cause difficult repair of defective parts due to irreversible deformation characteristics of PE materials, and finally, the reliability of the product is obviously reduced. Disclosure of utility model The utility model aims to solve the technical problem of providing a flexible flat wire so as to solve the problem that the front-end stitch of a golden finger is easy to warp or deform in the conventional flexible flat wire. In order to solve the technical problems, the flexible flat wire comprises a conductor layer, a glue layer and two layers of insulating layers, wherein the conductor layer comprises a main body part and a bare part which are connected with each other, the two layers of insulating layers are symmetrically coated on the upper surface and the lower surface of the main body part, the bare part comprises a connecting part and a front end part, one end of the connecting part is connected with the main body part, the other end of the connecting part is connected with the front end part, and the glue layer is arranged on the front end part. Further, in the flexible flat cable of the present utility model, the flexible flat cable further includes a reinforcing plate, the reinforcing plate includes a first reinforcing portion and a second reinforcing portion connected to each other, the first reinforcing portion is covered on the insulating layer, the second reinforcing portion is covered on the exposed portion, and the second reinforcing portion is located on a surface of the exposed portion facing away from the adhesive layer. Further, in the flexible flat wire according to the present utility model, the thickness of the first reinforcing portion in the vertical height direction is smaller than the thickness of the second reinforcing portion in the vertical height direction to form a stepped reinforcing plate. Further, in the flexible flat wire according to the present utility model, the thickness of the second reinforcing portion is a sum of the thickness of the first reinforcing portion and the thickness of the insulating layer. Further, in the flexible flat wire according to the present utility model, two reinforcing plates are included, and the two reinforcing plates are symmetrically disposed.
