Description
Technical field
The utility model relates to back light source technique fields, and in particular to a kind of glue iron one suitable for reverse group backlight
Shell.
Background technique
In existing mobile phone development, narrow frame is main developing direction, and whole mobile phone requires frame narrow, i.e. interior of mobile phone
Backlight module similarly narrow frame is needed to be matched.
In the prior art, backlight is usually to carry out shape using whole iron-clad to fix, and in inside, addition various assemblies make
It is integrally flat to obtain backlight.And in this process, the inner end of iron-clad usually requires have a glue position fixed as pasting
Flexible circuit board (FPC) and the light source connected are pasted and are fixed on glue position by double-sided adhesive, so that overall structure is firm by position
Gu stablizing.
But it is more and more narrow now with frame requirement, in the case that overall structure is constant, it is merely able to reduce the width of glue position
Degree to reduce whole border width, if but glue position is too narrow, FPC cannot be fine be fixed, cause integrally-built
Bad stability is easy to happen a series of quality problems such as light leakage either dislocation.
Therefore, research can make the fixed backlight shell pasted and reach narrowed backlight module of FPC be of great significance.
Meanwhile carrying shell of the shell of glue iron one as backlight, it can be improved the producing efficiency of backlight, and enhance backlight
The structural stability in source.
Utility model content
The purpose of this utility model is that in view of the deficiencies of the prior art, providing a kind of glue suitable for reverse group backlight
One body shell of iron.One body shell of glue iron is the backlight shell suitable for reverse group backlight, can effectively shrink backlight source module
Narrow side, to improve the accounting of mobile phone screen.
The purpose of this utility model is achieved through the following technical solutions.
A kind of one body shell of glue iron suitable for reverse group backlight, including ferrous casings and injection molding colloid；The ferricrete
The bottom end setting of body is fluted, and the groove is used to install the FPC in reverse group backlight；The injection molding colloid integrated injection molding
On the ferrous casings.
Preferably, the groove is that the back of the bottom end of the ferrous casings outwardly protrudes the groove to be formed.
Preferably, size of the size of the groove not less than FPC in reverse group backlight.
Preferably, injection molding colloid position of integrated injection molding on the ferrous casings includes the four of ferrous casings
Circumferential edges.
It is furthermore preferred that the edge of the ferrous casings is the edge of inward curl, it is molded colloid integrated injection molding
Inside the edge of the inward curl of ferrous casings.
Still more preferably, the thickness of edge integrated injection molding of the injection molding colloid in ferrous casings is less than
The brim height of ferrous casings edge inward curl.
Still more preferably, injecting hole is all had on the edge of the ferrous casings.
Preferably, the top of the ferrous casings also has polymorphic structure.
It is furthermore preferred that the polymorphic structure includes the through-hole for being provided with the tip edges close to ferrous casings, Huo Zhekai
It is located at the groove structure of the tip edge of ferrous casings.
Still more preferably, the groove structure includes from the tip edge of ferrous casings to the bottom end side of ferrous casings
To recessed groove structure, the edge of groove structure is the edge of inward curl, and the injecting hole on edge is U-shaped breach.
Still more preferably, integrated injection molding of the injection molding colloid in through hole forms protrusion, is used for backlight
Including light guide plate, bright enhancement film and diffusion barrier structure contraposition installation.
Preferably, FPC outlet is offered on the bottom terminal ends edge of the ferrous casings.
Compared with prior art, the utility model is had the following advantages and beneficial effects:
Shell of one body shell of glue iron of the utility model for glue iron integrated injection molding, easy to form, high production efficiency, at
This is cheap；Meanwhile it is fluted in the setting of the bottom end of shell, the installation of the FPC suitable for reverse group backlight makes the backlight of reverse group
FPC can be firmly secured in groove and save adhesive glue position in source, so that glue position be reduced to mention so that frame integrally narrows
The accounting of high mobile phone screen.

Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with specific embodiments and drawings, but this
The protection scope and embodiment of utility model are without being limited thereto.
Embodiment 1
A kind of one body shell of glue iron suitable for reverse group backlight, main view and rearview difference are as depicted in figs. 1 and 2,
Including ferrous casings 1 and injection molding colloid 2；The bottom end setting fluted 3 of ferrous casings 1, groove 3 is for installing reverse group backlight
In FPC；2 integrated injection molding of colloid is molded on the ferrous casings 1；It is also opened on the bottom terminal ends edge of ferrous casings 1
Equipped with FPC outlet 5.
Wherein, as shown in figure 3, the back that groove 3 is the bottom end of ferrous casings 1 outwardly protrudes the groove to be formed, and groove 3
Size of the size not less than FPC in reverse group backlight.By the setting of groove there is the FPC in reverse group backlight specific
Fixed bit, and the FPC of reverse group backlight is mounted in groove, and LED light strip is located above FPC, realizes the reverse group of backlight, from
