Embodiment
The utility model is described in detail with reference to embodiment, embodiment is only of the present utility model preferred real
Mode is applied, is not to restriction of the present utility model.
Fig. 4 to Fig. 8 is referred to, the utility model provides a kind of circuit board fixation structure, and it is used for backlight module, described
Circuit board fixation structure includes：Backboard 1, fixing groove 5, at least a glue post 2, the first groove 6, the fixing groove 5 are formed at described
On backboard 1, for circuit board to be fixed；The glue post 2 is extended vertically in the fixing groove 5, for circuit board to be entered
Row positioning；Glue post 2 can be that cylinder can also be cuboid, but be not limited；First groove 6 is formed at described solid
Determine on groove 5, and positioned at fixing groove 5 and the junction of glue post 2, avoided because mould 11 wears with this, produced at the edge angle 4 of glue post 2
Fillet and interfere with circuit board 3, the problem of influenceing assembly precision, so as to improve yields and efficiency of assembling.
Preferably, the shape of cross section of first groove 6 is square, circular arc or triangle, but is not limited,
Square, circular arc and triangular structure are simple, easily fabricated；Mould 11 does not interfere with assembly precision after wearing.
Further, Fig. 5 and Fig. 6 are referred to, by taking square first groove 6 as an example, when just starting production, its first groove 6
Edge angle 4 is right angle, and after batch production, because mould 11 wears, the abrasion of the edge angle 4 of the first groove 6 is fillet, due to
The place for producing fillet does not coordinate directly with circuit board 3, so not influenceing assembly precision, improves efficiency of assembling.
Further, Fig. 7 and Fig. 8 are referred to, by taking the first groove of triangle 6 as an example, its principle and the square phase of first groove 6
Together, because the place for producing fillet does not coordinate directly with circuit board 3, so not influenceing assembly precision, production efficiency is improved；This
Place is preferably the first groove of circular arc 6, and the first groove of circular arc 6 is readily produced, and cost is low.
Referring to Fig. 4, further, as a preferred embodiment, the side of fixing groove 5 is provided with the second groove
7, the interior extension of second groove 7 extends to fixing groove 5 formed with first buckle of spring-piece type 8, first buckle of spring-piece type 8
It is interior.During assembling, the first buckle of spring-piece type 8 is broken into second groove 7, circuit board 3 is downwardly into, it is fixed by glue post 2
Position, after circuit board 3 is adjacent to backboard 1, circuit board 3 can be fixed by decontroling the first buckle of spring-piece type 8, and packaging efficiency is high, can weigh
Work is good.
Further, the described one end of the first buckle of spring-piece type 8 away from the second groove 7 is more than one close to the second groove 7
End, elasticity and the fixation of accentuator plate 3 of the first buckle of spring-piece type 8 can be improved.
Referring to Fig. 9, further, the opposite side of backboard 1 is provided with two the second buckles 9, will can be arranged on backboard 1
The opposite side of circuit board 3 fix, improve efficiency of assembling.
Further, the junction of 1 and second buckle of backboard 9 is provided with the 3rd groove 10, and the 3rd groove 10 is located at
On backboard 1, while improving assembly precision, the limitation that the displacement of the second buckle 9 and deformation can also be subject to is smaller, is not easy to be broken
It is disconnected.
Further, the 3rd groove 10 and the junction of the second buckle 9 use arc transition, can both avoid the second card
There is stress concentration when by external force at structural mutation in button 9, while arc transition connection is also played at structural mutation
Strengthening action, so as to improve the structural stability of the second buckle 9.
The utility model also provides a kind of display device, including the circuit board fixation structure described in any of the above-described.
Above example only expresses embodiment of the present utility model, and its description is more specific and detailed, but can not
