Abstract
The utility model relates to an elastic piece type plastic frame, which is applied to a backlight module and comprises a plastic frame body. The plastic frame body is composed of an integrated plastic frame fixed surface and a lateral wall arranged on the periphery of the plastic frame fixed surface and extending towards one side of the plastic frame fixed surface. A light guide plate placing groove is defined by the lateral wall and the plastic frame fixed surface. Elastic pieces are arranged on the inner sides of the lateral wall close to the light guide plate placing groove and provided with first ends and second ends. The first ends are fixedly connected onto the lateral wall, the second ends are free ends and extend towards the plastic frame fixed surface, and gaps are reserved between the second ends and the plastic frame fixed surface. By means of the elastic piece type design, a light guide plate is tightly clamped by the elastic pieces located all around after the plastic frame is fastened, thereby enabling shaking quantity of the light guide plate to be reduced, capable of meeting location performance of the light guide plate, reducing possibility of generating abrasive lightspots and improving yield of the light guide plate and the backlight module.

Preferably, the cross section of described shell fragment is curved.
Preferably, described shell fragment and described sidewall are integral connecting structure or dismountable free-standing syndeton.
Preferably; Described free-standing syndeton comprises the locating hole that is arranged on described side-walls, the shell fragment plug connector that is fixedly connected with described locating hole; Described shell fragment plug connector comprises reference column; Described shell fragment is fixedly installed on the outer wall of described reference column, and described reference column inserts described shell fragment is fixedly connected in the described sidewall.
Preferably, described locating hole and described reference column interference fit mutually.
Preferably, described locating hole and described reference column are match cylindric, are provided with position-limit mechanism between described locating hole and the described reference column.
Preferably, described position-limit mechanism comprises boss on the outer cylinder that is arranged on described reference column, be opened on the hole wall of described locating hole and the breach that matches with described boss, and described boss snaps in the described breach.
Preferably, first end of described shell fragment is fixedly connected on the described boss, and described breach connects described locating hole and described LGP standing groove.
Preferably, described reference column is the hollow-core construction that end sealing, an end open wide.
Preferably, be provided with described shell fragment on described each circumferential described sidewall of moulding frame.
Because technique scheme utilization; The utility model compared with prior art has advantage: because the utility model adopts the spring-piece type design; Shell fragment reduces LGP rolling momentum tightly clamping of LGP around moulding frame engaging back, can satisfy the LGP polarization; The possibility that reducing friction property bright spot produces has good lifting to LGP and backlight module yield.
