Description
Technical field
The utility model relates to a kind of flexible flat cable structure, espespecially a kind of flexible flat cable structure with good rigidity.
Background technology
Flexible flat flat cable (Flex Flat Cable, FFC) is a kind of novel data cable.Generally speaking, it is to adopt PETG (PET) or other insulating material and zinc-plated flat copper wire as thin as a wafer, made through the pressing of high-tech automation equipment.Because it has that core marshalling, transmission quantity are large, the feature such as small and exquisite, the convenient disassembly of flat structure, volume, tool pliability, can be simply and be applied to neatly each electronic product, as the use of data transmission cable.Flexible flat flat cable is particularly useful for the occasion of various high-frequency bendings, for example the connection of moving-member.On connecting, it not only can adopt connector to peg graft, and also can be directly welded on printed circuit board (PCB).
Yet, because the insulating material thermal endurance that flexible flat flat cable adopts is poor, therefore, in its manufacture process, can remove SI semi-insulation material in that one end that need to weld future, make that wire is exposed is beneficial to follow-up welding, and avoid causing other problems because of insulating material poor heat resistance.Please refer to Fig. 1, the decomposing schematic representation of the flexible flat cable structure that Fig. 1 is prior art.As shown in Figure 1, the flexible flat cable structure 10 of prior art includes the material 11 that insulate on, a conductor 12, once insulate material 13, a conductor trench 14 and a stiffener 15.Upper insulation material 11 includes again the material 112 that insulate on insulate on one first material 111 and one second, and lower insulation material 13 includes again one first time insulation material 131 and one second time insulation material 132.Conductor trench 14 includes again one first conductor trench 141 and one second conductor trench 142.In fact, conductor 12 is a plurality of cores that are arranged in parallel, and the first conductor trench 141 and the second conductor trench 142 can be after upper and lower insulation material 11,13 pressings, to be subject to the impression of conductor 12 extruding formation or to set in advance the groove on first time insulation material 131 and second time insulation material 132.
Please also refer to Fig. 2, the top view that the flexible flat cable structure fabrication that Fig. 2 is prior art completes.When making, can utilize auto-stitching equipment, conductor 12 is done to appropriate aiming at the material 112 of insulating on the material 111 of insulating on first, second, first time insulation material 131 and second time insulation material 132, then their are heated and are pressed into as a whole structure.Afterwards, then by stiffener 15 paste to second time insulation material 132, to complete the making of flexible flat cable structure 10.

But, although problem when this kind of structure solved welding, but new problem caused.When electronic product more and more moves towards compact, not only the pitch smaller of conductor 12, the thickness of conductor 12 and width also must diminish, the size diminishing makes the less rigid of conductor 12, without any insulation material in the situation that the conductor 12 of welding region 17 around provides support, conductor 12 is the torsional deformation because being subject to external force easily.When welding processing procedure, also easily there is the problems such as off normal, short circuit in conductor 12, and then affects welding quality simultaneously.
Therefore, how to design the flexible flat cable structure making new advances, solve the problem of structural rigidity deficiency, just become very important problem.
