Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention.
Preferred embodiment one:
The open a kind of backlight module of this preferred embodiment.As shown in Figures 2 to 6, this backlight module at least includes glue frame 1, backboard 2 and is arranged on the optical element group in glue frame 1 and backboard 2 limited area.Wherein, in the middle part of the sidewall of glue frame 1, it is provided with grab 11, backboard is provided with hole clipping 21, grab 11 and hole clipping 21 suitable.
The fastening structure utilizing grab 11 and hole clipping 21 makes the middle part of glue frame 1 can be fitted tightly on backboard 2, solves glue frame 1 because of the problem that crimp causes in the middle part of it and between backboard 2, gap is excessive, enhances the bulk strength of shell.
The concrete shape of grab 11 is not limit, it is possible to be fastened on backboard 2 at the middle part of glue frame 1.Preferably, the cross section of grab 11 is L-shaped, and the free end of grab 11 is connected in hole clipping 21.It is low that the grab 11 of this structure processes simplicity, cost, and the operation that grab 11 snaps in hole clipping 21 is very convenient.
In order to retain now chlamydate advantage, the sidewall of glue frame 1 is also provided with projection 12, backboard 2 is provided with through hole 22, projection 12 and through hole 22 suitable.Utilize the fit structure of projection 12 and through hole 22 to limit glue frame 1 in the vertical direction position.
