Embodiment

Please refer to Fig. 1 to Fig. 3, the utility model provides a kind of flexible flat pattern cable, and this flexible flat pattern cable 1 comprises flexible flat cable 2 and stiffening plate 3.Flexible flat cable 2 comprises an insulation material 22 and is arranged in the insulation material 22 and a plurality of plain conductors 24 that are arranged in parallel, those plain conductor 24 1 ends expose to the end of flexible flat cable 2 to form complex conduction contact 242, stiffening plate 3 is located on end one side of flexible flat cable 2, mechanism's intensity when being used for the conducting terminal overlap joint of reinforcement conductive junction point 242 and butt connector (not illustrating), and stiffening plate 3 is provided with a mark 32.

Insulation material 22 comprises that insulating barrier 222 reaches insulating barrier 224 on one, and this plain conductor 24 is coated between insulating barrier 222 and the following insulating barrier 224.Mark 32 on the stiffening plate 3 is an obvious visual straight line mark, this straight line mark is perpendicular to the length direction of flexible flat cable 2, and extend on the two short lateral margins 38 of stiffening plate 3, so when the user is plugged in butt connector with flexible flat pattern cable 1, this straight line mark can be aligned in arbitrary precalculated position on butt connector outer rim or the circuit board, use the flexible flat pattern cable 1 that shows the insertion butt connector and put in place, make the conductive junction point 242 and the conducting terminal (not illustrating) of butt connector form electrically overlap joint.

Stiffening plate 3 can be pi (PI) or the made light-permeable thin slice of polyethylene terephthalate (PET), and mark 32 has the color different with stiffening plate 3, makes stiffening plate 3 one side of taking up an official post all can obviously pick out the position of mark 32.Modes such as the generation type of mark 32 can be 3 integrally formed with stiffening plate, dyeing, drafting or attaching are reached.

Stiffening plate 3 also can be a double-colored stiffening plate, and it comprises the first area 34 and the second area 36 of different colours, so can form mark 32 on the boundary line between first area 34 and the second area 36, so is not limited thereto.The another kind of selection is, stiffening plate 3 can be designed to cloudy surface portion with first area 34, and the mode that second area 36 forms bright face forms a clearly visible boundary line, be enough to offer the operator and discern the mark 32 that aligns as the location, that is in the utility model, be not restricted to the generation type of mark 32, as long as whether the mark 32 on the stiffening plate 3 can discern positioned in alignment for operator, can be applied in the utility model.

Aforementioned known mark 32 is an obvious visual straight line mark, and its bearing of trend is vertical mutually with the length direction of flexible flat cable 2.And in other changed, as shown in Figure 4, straight line mark can be incoherent being arranged on the stiffening plate 3, but must extend at least on the two short lateral margins 38 of stiffening plate 3.Therefore during the flexible flat pattern of practical operation cable 1,, promptly represent flexible flat pattern cable 1 to insert enough degree of depth and not crooked as long as when mark 32 positions on the two short lateral margins 38 overlap with the precalculated position.What deserves to be mentioned is that straight line mark also can utilize empty notch geometry to reach except being the real lines shape.

In sum, flexible flat pattern cable of the present utility model is to utilize to be provided with one in order to the mark as aligning on stiffening plate, utilize this mark to aim at butt connector outer rim or other position again, with flexible flat pattern cable location is gone up in position with butt connector in conducting terminal electrically contact, solve traditional flexible flat cable the dark or shallow excessively problem of inserting is arranged easily, therefore the utility model not only can not expend man-hour and increase manufacturing cost, more can reach to promote yield and the purpose that reduces manufacturing cost.

In addition, as long as flexible flat pattern cable of the present utility model is at the soft line stiffening plate with mark that is sticked that comes of tradition, so just can form and have the flexible flat pattern cable of aiming at positioning function, because it is very simple on the structure, be easy to utilize the zygonema processing procedure to reach automation and produce in a large number, so can effectively reduce the time and the cost of the manufacturing.

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.
