Description

Technical Field

[0001] The utility model relates to the technical field of backlight plate structures, and more specifically to a backlight FPC outlet line protection structure. Background Art

[0002] The display device generally includes a backlight module and a display screen. The display screen is a non-luminous display element and needs the backplane of the backlight module to achieve the display function. Among them, power modules such as FPC circuit boards are usually dispersedly arranged on the backplane and electrically connected to the inner panel through the FPC circuit board. However, most backplanes use metal backplanes and have outlets for the FPC circuit board to pass through. Since the FPC circuit board will be repeatedly bent, pulled and rubbed against the metal edge of the outlet, it is easy to cause damage to the line and cause a short circuit, or even expose the cable and cause leakage. In order to avoid damage to the FPC circuit board, such as Figure 1 As shown, the traditional design is to manually stick single-sided tape 103 on both sides of the iron frame opening of the metal backplane 101 to protect the FPC circuit board 102. Manually sticking single-sided tape is inefficient, wastes a lot of time, is not conducive to rapid production, and increases costs. Utility Model Content

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Please refer to Figure 2 The embodiment of the utility model provides a backlight FPC outlet line protection structure, including a metal back plate 1 and at least one FPC circuit board 2. The various components of this embodiment are described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 2 As shown, at least one wire outlet 11 for the FPC circuit board 2 to pass through can be opened on the outer wall of the metal back plate 1, one end of the FPC circuit board 2 is located on the inner side of the metal back plate 1, and the other end of the FPC circuit board 2 passes through the wire outlet 11 to the outside of the metal back plate 1.

[0020] In this embodiment, a first protective portion 12 and a second protective portion 13 may be respectively protruded outwardly from the outer wall edges at both ends of the outlet 11 , and the first protective portion 12 is located close to the side of the FPC circuit board 2 connected to the metal back plate 1 .

[0021] Specifically, in order to prevent the FPC circuit board 2 from twisting at the wire outlet 11 due to size mismatch, the width of the wire outlet 11 may be greater than or equal to the width of the FPC circuit board 2 .

[0022] Preferably, the metal back plate 1 can be preferably set as an aluminum plate. In this embodiment, the metal back plate 1 is stamped with aluminum material to form an integrally formed aluminum plate, which can ensure the structural strength of the metal back plate 1 while reducing the weight of the back plate 1.

[0023] In other embodiments, the FPC circuit board 2 may also be replaced by an FPC line, which is not limited in this embodiment.

[0024] like Figure 3 and Figure 4 As shown, one end of the first protection portion 12 close to the wire outlet 11 can be bent outward, and one end of the second protection portion 13 close to the wire outlet 11 is first folded outward and then bent inward to extend.

[0025] Specifically, the opening shape of the wire outlet 11 can be set to be H-shaped, and the first protection portion 12 and the second protection portion 13 are horizontally spaced between two side edges of the wire outlet 11 .

[0026] In this embodiment, the cross-sectional shape of the second protection portion 13 may be U-shaped or V-shaped.

[0027] Furthermore, the bending parts of the first protection part 12 and the second protection part 13 are both arranged in an arc-shaped transition.

[0028] Among them, when the FPC circuit board 2 is bent and pulled relative to the wire outlet 11, the outward side of the FPC circuit board 2 close to the first protective part 12 can contact the inner curved surface of the first protective part 12, and the inward side of the FPC circuit board 2 close to the second protective part 13 can contact the outer curved surface of the second protective part 12, which can avoid damage to the FPC circuit board caused by direct hard contact or friction with the two ends of the wire outlet when the FPC circuit board is bent and pulled.

[0029] To sum up, compared with the traditional manual single-sided adhesive, the utility model optimizes the wire outlet structure of the metal backplane, can avoid damage to the FPC circuit board caused by direct hard contact or friction with the two ends of the wire outlet when the FPC circuit board is bent and pulled, and also improves production efficiency and reduces costs.
