Position cannot be exchanged with limited post 1243, otherwise can be caused in practical disassembly process, circuit board is difficult to dismantle.
Further, since the height of limited post 1243 is higher, after positioning column 1242 and the disengagement of strip hole 1123, limit
Position column 1243 is not disengaged with strip hole 1123 yet, movement of the limited post 1243 still to circuit board 110 on first level direction
Play good guiding role.
Further, in liquid crystal display device, the thickness of circuit board 110 is generally 1.6mm or so, therefore limited post 1243
Thickness use 1.5~2.5mm, illustratively, the height of limited post 1243 is 2.0mm.
The thickness of positioning column 1242 is 0.6~1.0mm, if the thickness of positioning column 1242 is higher than 1.0mm, in dismounting, is needed
Keep the deflection of circuit board 110 larger, the dismounting of circuit board could be completed；If the thickness of positioning column 1242 is less than 0.6mm, electricity
Road plate 110 is slightly distorted, and positioning column 1242 can be disengaged with circuit board 110, cannot play preferable position-limiting action, exemplary
, the thickness of positioning column 1242 is 0.8mm.
Further, groove is additionally provided on backboard supporting part, groove limits bullet for being abutted with elastic clamping hook
The displacement of property hook in vertical direction.
In actual manufacturing process, the structure for the unified specification that elastic clamping hook designs for production firm, i.e. elastic clamping hook
It can mostly just coordinate with the loading plate (or supporting part) of specific thicknesses and abut；Thus in actual bearer harden structure, surface
The wall thickness of the supporting part of setting usually is difficult to be effectively matched with the elastic clamping hook of regulatory specifications；When as smaller such as the thickness of supporting part,
So that elastic clamping hook be inserted into after card slot can not with the inner wall of the supporting part being arranged on loading plate against.
In order to avoid the generation of this problem, the embodiment of the present invention be arranged on supporting part abutted against with elastic clamping hook it is recessed
Slot, by the way that the groove is arranged to supplement corresponding fit dimension, the connection to ensure elastic clamping hook and card slot is reliable, solid to make
Determine structure more to stablize.
Illustratively, as shown in figures 13a andb, groove 1214 is set on supporting part 121, when circuit board 110 is fixed on
When on loading plate 120, hook 1111 is connected on the groove 1214 of supporting part 121, and corresponding cooperation is supplemented by groove 1214
Size, to ensure that elastic clamping hook 1111 and the connection of card slot 1211 are reliable, to make fixed structure more stablize.
