Embodiment
Technological means and the effect thereof taked for further setting forth the utility model are described in detail below in conjunction with preferred embodiment of the present utility model and accompanying drawing thereof.
See also Fig. 2 and Fig. 3, the utility model provides a kind of flexible flat-type cable structure, this flexible flat-type cable structure comprises a flexible flat cable 3, it reaches the insulating barrier 32 that coats up and down those plain conductors 31 by several plain conductors 31 that are arranged in parallel and is formed, wherein insulating barrier 32 comprises the upper insulating barrier 321 and lower insulating barrier 322 of the upper and lower surface that is covered in those plain conductors 31, flexible flat cable 3 utilizes several cutting seams 30 to extend so that flexible flat cable 3 cutting separated times are formed several first separated times 33 and several the second separated times 34 along the axis direction of plain conductor 31, is to form a buffer part 35 between several first separated times 33 and the second separated time 34.Comprise many strip metals wire 31 in first, second separated time 33,34, these a little plain conductors 31 are divided into holding wire and earth connection according to functional definition.
Several first separated times 33 and the second separated time 34 are parallel to each other overlapping to form one first line concentration section 36 and one second line concentration section 37 respectively, and buffer part 35 is located between the first line concentration section 36 and the second line concentration section 37.In the present embodiment, this buffer part 35 is not for arranging the non-separated time district of any separated time, and the first line concentration section 36 and the second line concentration section 37 are for being respectively equipped with the separated time district of several first separated times 33 and the second separated time 34.So be not limited to this, the another kind of selection is that this buffer part 35 also is provided with the separated time district of the first separated time 33 or the second separated time 34, bends stacked processing procedure but the buffering effect under take this buffer part 35 as the situation in non-separated time district better and easily carries out automation.
In the present embodiment, the first line concentration section 36 is formed by several the first separated time 33 mutual storehouses, the second line concentration section 37 is formed by several the second separated time 34 mutual storehouses, the width of every first separated time 33 equals the width of every second separated time 34, the height of the first line concentration section 36 equals the height of the second line concentration section 37, so the practice just looks like that the line concentration section that existing single length is long deliberately is divided into the short line concentration section of two length, then between two line concentration sections, have additional buffer part 35, the effect of the larger torsion that the line concentration section that utilizes this buffer part 35 to reach original single of buffering bears, so just can solve prior art and produce easily the problem that the part separated time damages, tell the generation of problem so as to avoiding the visitor.So be not limited to this, the another kind of selection is that as shown in Figure 4, the width of every first separated time 33 can be not equal to the width of every second separated time 34, so so that the height of the first line concentration section 36 is not equal to the height of the second line concentration section 37, so as to the difference of the height width of the spatial design that cooperates product.At this moment, buffer part 35 also can be used as the first separated time 33 of separating two kinds of different in width and the effect of the second separated time 34 except the effect that the buffering twisting force is arranged.
Coating layer 4 be surrounded on the first line concentration section 36 and the second line concentration section 37 around, wherein coating layer 4 gets loose at random in order to first, second line concentration section 36 that is coated and fixed, first, second separated time 33,34 of 37 to avoid first, second separated time 33,34.In the present embodiment, coating layer 4 comprises one first coating layer 41 and one second coating layer, 42, the first coating layers 41 the first line concentration section 36, the second coating layers 42 second line concentration section 37 that is coated and fixed that is coated and fixed.Be understandable that, can set up in addition one the 3rd coating layer (not shown), the 3rd coating layer be coated and fixed simultaneously the first coating layer 41, buffer part 35 and the second coating layer 42, so with first, second line concentration section 36,37 and buffer part 35 be fixed into one.So be not limited to this, the another kind of selection is, also can be separately only with a coating layer 4 just can be coated and fixed simultaneously the first line concentration section 36, buffer part 35 and the second line concentration section 37 with first, second line concentration section 36,37 and buffer part 35 be fixed together, that is this coating layer 4 can replace the combination of the first coating layer 41, one second coating layer 42 and the 3rd coating layer.
In the present embodiment, first, second line concentration section 36,37 is formed at respectively two sides of buffer part 35, the first line concentration section 36 bends to left with respect to buffer part 35, the second line concentration section 37 with respect to buffer part 35 to right-hand bending, and make the Width of first, second line concentration section 36,37 length direction and buffer part 35 parallel to each other, that is first, second line concentration section 36,37 is with respect to buffer part 35 bendings 90 degree.In addition, flexible flat cable 3 has a relative front inserted terminal 38 and a rear inserted terminal 39, between front inserted terminal 38 and rear inserted terminal 39, sequentially form the first line concentration section 36, buffer part 35 and the second line concentration section 37, first, second line concentration section 36,37 is close to a side of buffer part 35, except shown in Figure 3 be separated from each other do not contact, the another kind of selection be, storehouse is together each other for a side that also first, second line concentration section 36,37 can be close to buffer part 35.
It is worth mentioning that, the spacing size that those plain conductors are 31 is because the impact of downsizing is contracted to the width less than plain conductor 31, therefore the utility model can be selected each cutting seam 30 directly is arranged on the earth connection among those plain conductors 31, just can effectively solve the problem that the cutting separated time yield of prior art descends.In the present embodiment, coating layer 4 is a conductive fabric, this conductive fabric be surrounded on first, second line concentration section 36,37 around the time can form and electrically conduct with first, second separated time 33,34 earth connection, so can reach the purpose of prevention Electromagnetic Interference (EMI).
In addition, a connector joint (not shown) can be set in addition in the front inserted terminal 38 of flexible flat cable 3 or rear inserted terminal 39, this adapter connector comprises a lower house and a upper shell, the end of those plain conductors 31 of flexible flat cable 3 exposes to insulating barrier 32 to form several conductive junction points, and the end of flexible flat cable 3 is located between lower house and the upper shell and exposes those conductive junction points and forms a line-end connector.
In sum, the utility model flexible flat-type cable structure will have single line concentration section now and be divided into two line concentration sections, and between two line concentration sections, have additional a buffer part, the effect of the larger torsion that the line concentration section that utilizes this buffer part to reach existing single of buffering bears, so just can solve prior art and produce easily the problem that the part separated time damages, tell the generation of problem to avoid the visitor.
The above; for the person of ordinary skill of the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and technical conceive, and all these changes and distortion all should belong to the protection range of the utility model claim.
