Abstract
A fixture construction for printed circuit board in LCD module comprises a printed circuit board and a back board, wherein the back plate comprises a plurality of back board bosses integrally projecting outwards, and further a dual surface conductive adhesive, with one surface adheres to the printed circuit board, and the other surface adheres to back board bosses. The back plate further comprises at least one positioning convex hull disposed on bottom end of back board, and the printed circuit board is equipped with at least one positioning slot corresponding to the positioning convex hull. The fixture construction of the printed circuit board in the LCD module has advantages of simple construction, capability of fast and conveniently implementing PWB assembly and disassembly in the LCD module, saving time and labor force.
Description
[technical field]
The utility model is the parts fixed sturcture about a kind of liquid crystal display module, is meant the fixed sturcture of printed circuit board (PCB) in a kind of liquid crystal display module especially.
[background technology]
The liquid crystal display module mainly is made up of spare parts such as housing, glue frame, module backlight, driving circuit, glass substrate, control circuits, and module wherein backlight mainly is made up of spare parts such as light source, lampshade, backboard, light guide plate.
Consult shown in Figure 1ly, be illustrated as the rear view of present liquid crystal display module, this figure has mainly showed the combined state of backboard 1 and printed circuit board (PCB) (PWB, Printed wiring board) 2.Please consult shown in Figure 2ly simultaneously, be illustrated as the partial enlarged drawing of Fig. 1.Printed circuit board (PCB) 2 is by the bottom outer surface of screw 3 lockings at backboard 1.Comprise the backboard boss 12 on a plurality of one protrusion backboards 1 surface on the backboard 1, and be arranged on the connector 14 on the backboard 1.Its dorsulum boss 12 is interior hollow structure; thereby be mainly the locking point that supporting printing board 2 is protected the circuit of backboards 1 inboard and screw is provided; be that screw 3 passes printed circuit board (PCB) 2 and backboard boss 12 successively; thereby on backboard 1, connector 14 effects are the signals that receive from customer facility with printed circuit board (PCB) 2 lockings.
See also shown in Figure 3ly, be illustrated as the side isometric view of present liquid crystal display module.Can find out more clearly that printed circuit board (PCB) 2 locks on backboard boss 12 by screw 3.
In sum, PWB in the liquid crystal display module locks on backboard by screw at present, so the PWB of liquid crystal display module assembles and disassembles Shi Junxu and carry out screwing of screw or open pine, waste time and energy, and the screw volume is too little, is easy to lose, and not only further increases the number of working processes, and the increase production cost, so should do corresponding improvement.
[summary of the invention]
Technical problem to be solved in the utility model is to provide a kind of simple in structure, the fixed sturcture that can realize printed circuit board (PCB) in the liquid crystal display module that PWB assembles and dismantle quickly and easily in the liquid crystal display module.
The utility model solves the problems of the technologies described above by the following technical programs: the fixed sturcture of printed circuit board (PCB) in a kind of liquid crystal display module, comprise printed circuit board (PCB) and backboard, described backboard comprises a plurality of backboard boss that are positioned at the bottom and outwards protrude from the backboard one, also comprise two-sided conducting resinl, a glue face adhesion printed circuit board (PCB) of described two-sided conducting resinl, another glue face adhesion backboard boss.
This utility model can further be specially:
Also comprise and protrude at least one the location convex closure that is arranged on the backboard bottom, corresponding to this location convex closure at least one locating slot is set on the described printed circuit board (PCB).
The advantage of the fixed sturcture of printed circuit board (PCB) is in the utility model liquid crystal display module: simple in structure, can realize quickly and easily that PWB assembles and dismantles in the liquid crystal display module, and more save man-hour and save the labour.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
