Detailed Description
The present utility model will be further described with reference to the following examples and drawings, which are not intended to limit the scope of the utility model.
Examples
As shown in fig. 1-3, this embodiment discloses a flexible flat cable, including conductor 1, stiffening plate 2 and first protection film 3, conductor 1 includes in proper order along its length direction can cut portion 11, welding portion 12 and laminating portion 13, stiffening plate 2 laminating in the up end of can cut portion 11, first protection film 3 laminating in the up end of laminating portion 13, conductor 1 does not laminate and has the exposed position of stiffening plate 2 and first protection film 3 to form welding portion 12, welding portion 12 is used for processing welding. The strength of the conductor 1 is improved by arranging the reinforcing plate 2, the occurrence of PIN tilting or skew in the test process can be prevented, the flexible flat cable can be directly processed and welded after the test is finished by leaving the welding part 12 of the exposed part between the reinforcing plate 2 and the first protective film 3, and the flexible flat cable is further prevented from being bent or deformed by arranging the first protective film 3.
The practical application process of the flexible flat cable of the embodiment is (1) testing, namely directly inserting the cuttable portion 11 and the welding portion 12 into a testing mother seat, and (2) processing and welding, namely cutting the cuttable portion 11 and the reinforcing plate 2 after the testing is completed, and directly welding the welding portion 12 of the exposed portion with an external electronic element.
