Abstract

The utility model relates to a backlight source structure of a firmly assembled PCB (printed circuit board). The backlight source structure mainly comprises a light guide plate and a PCB, wherein the light guide plate is provided with a clamping slot and a bayonet; and the PCB is provided with a clamping position corresponding to the position of the bayonet. In assembly, the PCB is embedded in the clamping slot of the light guide plate. When the clamping position and the bayonet are matched for assembly, the whole PCB is embedded in the clamping slot of the light guide plate, then the clamping position on the PCB is matched with the bayonet on the light guide plate, and then a clamping hook position on the PCB is matched with an inverted hook bayonet of the light guide plate, and so the PCB can be firmly clamped. In the backlight source structure, the PCB can be firmly assembled on the light guide plate without dispensing glue, and the assembly is simple and firm.

Description

The back light source structure of a kind of firm assembling PCB

Technical field

The utility model relates to the photovoltaic field, particularly relates to the back light source structure of a kind of firm assembling PCB.

Background technology

At present, it is more that backlight uses in the product of photoelectric field, present backlight; it generally all is to adopt when assembling PCB, the method processing that fastens with glue; but this kind method is pasted not strongly solid in actual applications through regular meeting, and causes scrapping of product easily.

The utility model content

The purpose of this utility model is to provide the back light source structure of a kind of firm assembling PCB, and it can overcome above-mentioned defective, and assembling is firmly simple.

In order to solve the problem that prior art exists, the technical scheme that the utility model adopted is:

The back light source structure of a kind of firm assembling PCB, it mainly comprises LGP and pcb board, wherein: described LGP is provided with draw-in groove and bayonet socket, the position of corresponding described bayonet socket is provided with screens on the described pcb board, during assembling, described pcb board is embedded in the draw-in groove of described LGP, described screens and described bayonet fittings.

Preferably, also be provided with the barb bayonet socket on the above-mentioned LGP, on the described pcb board, be provided with the grab position of matching with described barb bayonet socket with the corresponding position of described LGP.

After adopting said structure, during assembling, the whole piece pcb board is embedded in the draw-in groove of LGP, then, the screens on the pcb board is matched with bayonet socket on the LGP, matched with the barb bayonet socket of LGP in grab position on the pcb board, like this, just can block pcb board very securely, this is novel, do not need a glue that pcb board firmly is assemblied on the LGP, assembling is simple and firm.

The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As shown in Figure 1, 2, the utility model discloses the back light source structure of a kind of firm assembling PCB, it mainly comprises LGP 1 and pcb board 2, wherein:

LGP 1 is provided with draw-in groove 11, bayonet socket 12 and barb bayonet socket 13, the setting of draw-in groove 11, pcb board 2 can be blocked just to be established in it, in the present embodiment, bayonet socket 12 is provided with three, is separately positioned on the both sides and the centre of draw-in groove 11, cooperates shown in Fig. 3,4, barb bayonet socket 13 has two, is located at the both sides, top of draw-in groove 11 respectively.

Cooperate shown in Figure 5ly, the position of the bayonet socket 12 of corresponding LGP 1 and barb bayonet socket 13 is provided with screens 21 and grab position 22 on the pcb board 2.

During assembling, whole piece pcb board 2 is embedded in the draw-in groove 11 of LGP 1, then, screens 21 on the pcb board 2 is matched with bayonet socket 12 on the LGP 1, matched with the barb bayonet socket 13 of LGP 1 in grab position 22 on the pcb board 2, like this, just can block pcb board 2 very securely, this is novel, does not need a glue that pcb board 2 firmly is assemblied on the LGP 1.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
