Specific 31 He of the first insulating part that as shown in Fig. 2, in the utility model embodiment, which can also include
Second insulating part 32, the first insulating part 31 are connected to binding area 11 and extend towards screen 20 direction of body, and the second insulating part 32 is connected to
Shield body 20 and extends towards 10 direction of substrate.First insulating part 31 and the second insulating part 32 can dock one by one and have between the two
There is the second gap 42.Second gap 42 is located at two adjacent first conducting ends 111 or two adjacent second conducting ends
Between 21, so that the first gap 41 is mutually staggered with the second gap 42, it is ensured that have between two adjacent first gaps 41 exhausted
Edge object 30.As deformation, the first insulating part 31 and the second insulating part 32 can be mutually staggered without docking, then the first insulating part
31 and second in insulating part 32 should at least one extend beyond the first gap 41, two adjacent the first gaps 41 could be made
Between have insulant 30.
It is practical that when substrate 10 is layered on screen body 20, the first conducting end 111 is generally flush with the second conducting end 21 and docks, the
One insulating part 31 and the second insulating part are also concordant docking.
Along the extending direction of the first conducting end 111, the size in second gap 42 is changed on the size in the first gap 41
It is exhausted that the sum of development length of Yan Zhi, the first conducting end 111 and the second conducting end 21 is greater than or equal to the first insulating part 31 and second
The sum of the development length of edge part 32, so that the docking of the first insulating part 31 and the second insulating part 32 will not interfere with the first conducting end
111 and second conducting end 21 normal docking.

Development length can be 3 times of development length of the second insulating part 32.Certainly, the premise of this example is along the first conducting end
111 extending direction, the extension size of the size in the first gap 41 much smaller than the first conducting end 111 or the first gap
Size just has the first insulating part less than the half of the extension size of the first conducting end 111 so between two first gaps 41
31。
From above-mentioned two example as it can be seen that when the development length of the first conducting end 111 and the second conducting end 21 is equal, first
Gap 41 can be between substrate 10 and screen body 20 at the center of vertical range, i.e. the first gap 41 to substrate 10 and extremely screen
The vertical range of body is equal.Second gap 42 can then be located at 1/3 or 2/3 of vertical range between substrate 10 and screen body 20,
That is the vertical range of the second gap 42 to substrate 10 and the first gap 41 is equal, or to screen body 20 and the first gap 41 it is vertical away from
From equal.Since a part can be connected with each other in the conducting resinl in the first adjacent gap 41 with shortest linear distance, there are also one
Part be then be spilled over to along the first conducting end 111 or the second conducting end 21 substrate 10 or screen body 20 on, therefore substrate 10 or
Accumulation conducting resinl is relatively easy on screen body 20.Therefore, the second gap 42 not only needs phase of keeping at a distance between the first gap 41
Mutually be staggered, can not get too close to substrate 10 or screen body 20, therefore by the second gap 42 setting substrate 10 and screen body 20 it
Between vertical range 1/3 or 2/3 at can more efficiently reduce screen body 20 and substrate 10 on short circuit phenomenon generation.
In the utility model embodiment, appearance should be formed between insulant 30 and the first conducting end 111, the second conducting end 21
Glue distance, the appearance glue distance can accommodate conducting resinl, the conducting resinl overflowed from the first gap 41 enabled to flow to insulation
Between object 30 and the first conducting end 111 and between insulant 30 and the second conducting end 21.In the first adjacent conducting end 111
Between keep interval, also keep interval between the second adjacent conducting end 21, the size of space can be to hold glue apart from the two of size
Times or more, such as three times or four times etc..
