First binding block 220 and first pin 140 binding is simultaneously after the second wiring board of reflexed 240, at the first through hole 212 outside
Air-extractor is connect, negative pressure can be formed between 210 and second wiring board 240 of first line plate during air-extractor is evacuated, and
The adsorption capacity to the second wiring board 240 is generated, so as to so that the second wiring board 240 is flat as far as possible with first line plate 210
Row, prevents the second wiring board 240 from tilting.Also it is ensured that being aligned between the second wiring board 240 and touch control conductive film 100 accurate
Degree, and then the reliability bound between flexible PCB 200 and touch-control conductive film 100 is improved, ensure the smooth transmission of signal.
In combination with Fig. 8, in the present embodiment, the second wiring board 240 is exposed to the region of touch control conductive film frontside edge
On offer the second through hole 242, when the first binding block 220 binds block 250 respectively opposite with touch control conductive film 100 two with second
When face is bound, orthographic projection of second through hole 242 on first line plate 210 is spaced with first through hole 212.
The design of second through hole 242 can further improve adsorption capacity of the air-extractor to the second wiring board 240, so that
It is more smooth to obtain the second wiring board 240.Moreover, the second through hole 242 is staggered with first through hole 212 and belongs to fool-proof design, energy
Enough avoid air-extractor invalid to the suction-operated of the second wiring board 240.
Further, in the present embodiment, first through hole 212 is equipped with multiple, is disposed side by side on first line plate 210.
Multiple first through hole 212 can increase the bleed-off passage of air-extractor, increase the adsorption area to the second wiring board 240, into one
Step improves the precision aligned between the second binding block 250 and second pin 170.
In addition, the second through hole 242 can also be equipped with it is multiple, be disposed side by side on the second wiring board 240, and when first binding
Block 220 and the second binding block 250 be when the two sides opposite with touch control conductive film 100 is bound respectively, and the second through hole of each two 242 is the
First through hole 212 there are one being set between orthographic projection on one wiring board 210.Namely second through hole 242 interlock with first through hole 212
Arrangement, this also belongs to fool-proof design.
In the present embodiment, connecting plate 230 is in rectangular-shape, in order to produce.In other embodiments, connecting plate
230 can also be arch, in order to overturn the second wiring board 240.
For different types of touch control conductive film 100, position and second of first pin 140 on first surface 112
Position of the pin 170 on second surface 114 is there are many situation, so as to which the first binding block 220 and second binds block 250 in touch-control
Binding position on conductive film 100 is also not quite similar.
