For the utility model that achieves the above object provides a kind of flexible flat cable, formed by a plurality of plain conductors that are arranged in parallel and the insulating barrier that coats those plain conductors, the end of those plain conductors exposes to this insulating barrier to form the complex conduction contact, and this flexible flat cable comprises:
Contact site before one is arranged at this flexible flat cable front end, and this preceding contact site is provided with those conductive junction points; And contact site after two, being arranged at this flexible flat cable rear end, this two backs contact site is provided with those conductive junction points, and this two backs contact site is to misplace each other to separate.
For the utility model that achieves the above object provides a kind of flexible flat cable, more comprise: one first winding displacement part is arranged between this preceding contact site and this back contact site; And one second winding displacement part, be arranged between this preceding contact site and another this back contact site, form a joint-cutting between this first winding displacement part and this second winding displacement part, this joint-cutting is to extend towards this preceding contact site from this flexible flat cable rear end.
For the utility model that achieves the above object provides a kind of flexible flat cable, wherein this first winding displacement part is uneven in length in the length of this second winding displacement part.
For the utility model that achieves the above object provides a kind of flexible flat cable, wherein this first winding displacement part and this second winding displacement part are to utilize the hot pressing processing procedure to be integrally formed as this flexible flat cable earlier, the rear end that utilizes this joint-cutting to cut to wear this flexible flat cable to be forming this two backs contact site, and this joint-cutting is that front end along the axis direction of this plain conductor towards this flexible flat cable extends to this preceding contact site to form this first winding displacement part and this second winding displacement part.
For the utility model that achieves the above object provides a kind of flexible flat cable, wherein should be provided with a preset clearance between those conductive junction points of preceding contact site, this preset clearance is corresponding to this joint-cutting setting.
Compare with conventional art, the utlity model has following beneficial effect: flexible flat cable provided by the utility model, it is to utilize cutter cutting itemize on the rear end of flexible flat cable with contact site after forming two, contact site after these two is assembled two different connectors respectively, so can form a pair of two contact form, can't be matched with the miniaturization of mobile electronic device and the problem of Portable spatial design to solve known flexible flat cable.In addition, flexible flat cable of the present utility model need just can not reach the purpose that two back contact sites misplace each other and separate by the mode of folding.

Embodiment
See also Fig. 1 and shown in Figure 2, flexible flat cable 1 of the present utility model comprises by a plurality of plain conductors 11 that are arranged in parallel and the insulating barrier 12 that coats those plain conductors 11 and being formed that the end of those plain conductors 11 exposes to insulating barrier 12 to form complex conduction contact 111.
Contact site 13 before flexible flat cable 1 comprises one, two back contact sites 14, one first winding displacement part 15 and one second winding displacement part 16, preceding contact site 13 is arranged at flexible flat cable 1 front end and is provided with those conductive junction points 111, two back contact sites 14 are arranged at flexible flat cable 1 rear end and are provided with those conductive junction points 111, first winding displacement part 15 is arranged between preceding contact site 13 and the back contact site 14, second winding displacement part 16 is arranged between preceding contact site 13 and another back contact site 14, and form a joint-cutting 17 between first winding displacement part 15 and second winding displacement part 16, this joint-cutting 17 is contact site 13 extensions forward from flexible flat cable 1 rear end.
In the present embodiment, because being uneven in length in the length of second winding displacement part 16 of first winding displacement part 15 makes that two back contact sites 14 are can misplace each other to separate, therefore just do not need again to reach not isometric purpose by the mode of folding.In addition, first winding displacement part 15 and second winding displacement part 16 are to utilize the hot pressing processing procedure to be integrally formed as flexible flat cable 1 earlier, the back rear end that utilizes joint-cutting 17 to cut to wear flexible flat cable 1 forming two back contact sites 14, this joint-cutting 17 be before the front end along the axis direction of this plain conductor 11 towards flexible flat cable 1 extends to contact site 13 to form first winding displacement part 15 and second winding displacement part 16.
What deserves to be mentioned is, be provided with a preset clearance L1 between those conductive junction points 111 of contact site 13 before this, this preset clearance L1 is provided with corresponding to joint-cutting 17, spacing L2 in first winding displacement part 15 and second winding displacement part 16 between adjacent two plain conductors 11, the size of this preset clearance L1 is greater than spacing L2, so can make flexible flat cable 1 can provide enough headspaces to cut to joint-cutting 17 and use to form first winding displacement part 15 and second winding displacement part 16.
In sum, flexible flat cable of the present utility model, it is to utilize cutter cutting itemize on the rear end of flexible flat cable with contact site after forming two, contact site after these two is assembled two different connectors respectively, so can form a pair of two contact form, can't be matched with the miniaturization of mobile electronic device and the problem of Portable spatial design to solve known flexible flat cable.In addition, flexible flat cable of the present utility model need just can not reach the purpose that two back contact sites misplace each other and separate by the mode of folding.
Above-mentioned detailed description is at a kind of preferable possible embodiments explanation of the utility model, but this embodiment is not in order to limit claim of the present utility model, all other do not break away from the equalization of being finished under the skill spirit that the utility model discloses to be changed and modifies change, all should be contained in the claim that the utility model contains.
