Technical Field
The utility model relates to the technical field of backlight sources, in particular to a backlight source capable of preventing FPC from being scratched.
Background
At present, a notch is required to be reserved on an iron frame of a backlight source for a flexible circuit board to extend out of the back face of the iron frame, the flexible circuit board is required to be attached to the back face of the iron frame after extending out, and the flexible circuit board is easily scratched due to burrs on the edges of the notch, so that products are scrapped, and therefore, the backlight source for preventing FPC scratch is provided.
Disclosure of Invention
The utility model aims to solve the technical problems that the prior art is overcome and the backlight source for preventing the FPC from being scratched is provided, so that the problems that a notch is reserved on an iron frame of the backlight source in the prior art for a flexible circuit board to extend out of the back surface of the iron frame, the flexible circuit board needs to be attached to the back surface of the iron frame after extending out, and the flexible circuit board is scratched easily due to burrs on the edges of the notch, so that the product is scrapped are solved.
In view of the above, the utility model provides a backlight source for preventing FPC scratch, which comprises an iron frame, wherein a notch is formed in the back surface of the iron frame near the frame edge, a flexible circuit board is inserted into the inner side of the iron frame through the notch, and a black glue layer extending to the inner part of the iron frame is arranged at the edge of the notch.
Preferably: the thickness of the black glue layer is 0.2-0.4 mm.
Preferably: the notch is arranged in a strip shape.
Preferably: the black glue layer is arranged on one side of the notch far away from the frame edge and covers a part of the area on the back of the iron frame.
Preferably: the width of the black glue layer is larger than that of the flexible circuit board.
From the above technical solutions, the embodiment of the present utility model has the following advantages:
according to the backlight source for preventing the FPC from being scratched, the black adhesive layer is adhered to the edge of the notch, so that burrs are prevented from being exposed, and when the flexible circuit board is required to be adhered to the back surface of the iron frame after extending out, the burrs cannot scratch the flexible circuit board, so that the protection effect of the flexible circuit board is realized.
These features and advantages of the present utility model will be disclosed in detail in the following detailed description and the accompanying drawings.
Drawings
The utility model is further described with reference to the accompanying drawings:
FIG. 1 is a schematic diagram of the structure of the present utility model;
fig. 2 is an enlarged view of fig. 1 at a in accordance with the present utility model.
Reference numerals illustrate: 1. an iron frame; 2. a notch; 3. a flexible circuit board; 4. and a black glue layer.
Detailed Description
The technical solutions of the embodiments of the present utility model will be explained and illustrated below with reference to the drawings of the embodiments of the present utility model, but the following embodiments are only preferred embodiments of the present utility model, and not all embodiments. Based on the examples in the implementation manner, other examples obtained by a person skilled in the art without making creative efforts fall within the protection scope of the present utility model.
The backlight source for preventing FPC scratch according to the embodiment of the utility model is specifically described below with reference to the accompanying drawings.
Examples
In order to facilitate understanding, referring to fig. 1 to 2, an embodiment of a backlight source capable of preventing FPC from being scratched provided by the utility model comprises an iron frame 1, wherein a notch 2 is formed in the back surface of the iron frame 1 near a frame edge, a flexible circuit board 3 is inserted into the inner side of the iron frame 1 through the notch 2, and a black glue layer 4 extending into the iron frame 1 is arranged at the edge of the notch 2.
It should be noted that, at present, a notch is required to be reserved on the iron frame of the backlight source for the flexible circuit board 3 to extend out from the back surface of the iron frame 1, the flexible circuit board 3 needs to be attached to the back surface of the iron frame 1 after extending out, and the black glue layer 4 is attached to the edge of the notch 2, so that burrs are prevented from being exposed, and the protection effect of the flexible circuit board 3 is realized.
In an alternative embodiment: the notch 2 is arranged in a strip shape. The black glue layer 4 is arranged on one side of the notch 2 far away from the frame edge and covers a part of the area on the back of the iron frame 1. The width of the black glue layer 4 is larger than that of the flexible circuit board 3, and the thickness of the black glue layer 4 is 0.2-0.4 mm.
It should be noted that, a better protection effect can be achieved by using a black glue layer 4 with a proper thickness.
Working principle: when the flexible circuit board 3 is used, the flexible circuit board 3 is required to be attached to the back surface of the iron frame 1 after being stretched out, and the black glue layer 4 is attached to the edge of the notch 2, so that burrs are prevented from being exposed, and the protection effect of the flexible circuit board 3 is realized.
The above embodiments are only for illustrating the technical solution of the present utility model, and not for limiting the same; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
