Embodiment
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
A kind of module backlight of liquid crystal indicator, shown in module backlight comprise: glue frame 100 and backboard 200.
Buckle 110 is stuck in the through hole 211.
Adopt this kind structure can avoid the use of screw retention backboard and glue frame, the glue frame that has caused when having avoided playing screw is out of shape, thereby avoids the details in a play not acted out on stage, but told through dialogues light leak of liquid crystal indicator, has improved yield rate, has practiced thrift cost
An embodiment of the present invention such as Fig. 2 are to shown in Figure 4.
Bridging 210 is the bridge-type structure towards the protruding bending of glue frame 100 1 sides.
The buckle 110 of glue frame 100 has certain retractility, and buckle 110 is away from the size of the end 112 of the body of glue frame 100 size less than through hole 211.After this end 112 of buckle 110 gets into through hole 211; Press buckle 110 gradually downwards; Because the size of buckle 110 becomes greatly gradually, when the size of buckle 110 during greater than the size of through hole 211, buckle 110 contractions; After moving down certain distance again, the draw-in groove 111A of the lateral ridge 111 of buckle 110 is stuck in through hole 211 edges.Glue frame 100 is fixed on the backboard 200 at this moment.
Adopt this kind mode fixing glue frame 100 and backboard 200, can reduce the deflection of glue frame 100, and can make glue frame 100 and backboard 200 firm cooperating, guaranteed the flatness in glue frame 100 fronts, make it when being assembled into complete machine, alleviate the details in a play not acted out on stage, but told through dialogues light leak greatly.
Preferably, two minor faces and a long limit towards the one side of backboard 200 of glue frame 100 have buckle 110., be furnished with buckle 110 here, be used for backboard 200 fixing on three limits, the back side of glue frame 100.Particularly, the both sides minor face respectively is furnished with the long limit of 3 buckle 110, one sides and is furnished with 4 buckles 110.
Further, also have buckle, cooperate, be used to strengthen fixation with backboard 200 at the side of glue frame 100.
A kind of manufacturing approach of module backlight of liquid crystal indicator is as shown in Figure 5, shown in module backlight comprise: glue frame and backboard.Said manufacturing approach comprises the steps.
Step S100 is provided with buckle at the glue frame towards the one side of backboard.
Step S200 is provided with the bridging of bending at backboard, and the position corresponding with buckle is provided with through hole putting up a bridge.
Step S300 is stuck in buckle in the through hole.
Adopt this method can avoid the use of screw retention backboard and glue frame, the glue frame that has caused when having avoided playing screw is out of shape, thereby avoids the details in a play not acted out on stage, but told through dialogues light leak of liquid crystal indicator, has improved yield rate, has practiced thrift cost;
Preferably, said buckle is set to away from the size of the end of the body of the said glue frame size less than said through hole; Near the size of the end of the body of said glue frame size greater than said through hole.
Preferably, at said buckle lateral ridge is set; Near the end of the body of said glue frame draw-in groove is set at said lateral ridge; Said draw-in groove is stuck in the edge of said through hole.
Preferably, on one side said lateral ridge is stretched out to the body direction of said glue frame from the end of buckle away from the body of said glue frame on one side.
The buckle of glue frame has certain retractility, and buckle is away from the size of the end of the body of the glue frame size less than through hole.This end of buckle press buckle downwards after getting into through hole gradually, because the size of buckle becomes greatly gradually, when the size of buckle during greater than the size of through hole, buckle contraction, after moving down certain distance again, the draw-in groove of the lateral ridge of buckle is stuck in the through hole edge.This moment, the glue frame was fixed on the backboard.
Adopt this kind mode fixing glue frame and backboard, can reduce the deflection of glue frame, and can make firm the cooperating of glue frame and backboard, guaranteed the positive flatness of glue frame, make it when being assembled into complete machine, alleviate the details in a play not acted out on stage, but told through dialogues light leak greatly.
Preferably, on two minor faces and a long limit of glue frame buckle is set towards the one side of backboard.
, be furnished with buckle here, be used for fixing with backboard on three limits, the back side of glue frame.Particularly, the both sides minor face respectively is furnished with 3 buckles, and the long limit of a side is furnished with 4 buckles.
Further, also have buckle, cooperate, be used to strengthen fixation with backboard at the side of glue frame.
The above is merely preferred embodiment of the present invention, is not to be used to limit protection scope of the present invention.All any modifications of within spirit of the present invention and principle, being done, be equal to replacement, improvement etc., all be included in protection scope of the present invention.
