Technical Field
[0001] This utility model relates to the field of backlight technology, and in particular to an ultra-thin LED backlight module. Background Technology
[0002] Backlight is a light source located behind an LCD display, and its light emission effect directly affects the visual effect of the LCD display module.
[0003] The ultra-thin LED backlight embeds components within a frame, using flexible circuitry to achieve its ultra-thin profile. The backlight has exposed connectors; prolonged disuse can allow dust to accumulate at these connectors, potentially affecting the connection.
[0004] In view of this, we propose an ultra-thin LED backlight module. Utility Model Content
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide an ultra-thin LED backlight module to solve the technical problem that dust at the current plug-in point can affect the connection.

[0007] The outer frame is fitted around the ultra-thin outer shell of the backlight body;
[0008] The outer frame has an opening on one side, and the opening of the outer frame corresponds to the wiring terminal of the backlight body.
[0009] The seal is placed inside an opening on one side of the outer frame;
[0010] The seal is fitted in a closed manner with the terminal block;
[0011] The seal has grooves at both ends, and abutment springs are arranged in the grooves. The abutment springs abut against the abutment grooves on the inner wall of the opening side of the outer frame.
[0012] Preferably, the abutment spring is designed with an arc shape, the arched end of the abutment spring is located outside the groove, and the arched end of the abutment spring is adapted to the arc-shaped abutment groove.
[0013] Preferably, the two ends of the abutting spring are respectively provided with inserts, and the inner ends of the two side walls of the groove are respectively provided with embedding grooves, and the inserts are inserted into the embedding grooves.
[0014] Preferably, the outer side of the outer end of the insert is provided as a slope, and the area of the insert end is smaller than the area of the inlet port of the embedding groove.
[0015] Preferably, guide blocks are fixed on the upper and lower sides of both ends of the seal, and the protruding end of the guide block is matched with the opening end of the outer frame.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. This utility model, by setting an outer frame, sealing strip, abutment spring, and abutment groove, has the advantage of quickly inserting the sealing strip into the opening on one side of the outer frame when not in use for a long time, sealing the wiring terminal and preventing dust from entering. It solves the problem that dust will enter the backlight when it is not used for a long time, and that dust at the plug will affect the connection.

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0032] Example 1: An ultra-thin LED backlight module, see [link / reference] Figures 1 to 5 The backlight body 1 mainly includes a light source, a light guide plate, a reflector, a diffusion film, a brightness enhancement film, circuitry, etc., all housed within an ultra-thin frame shell. It also includes an outer frame 2 and a sealing strip 3. The outer frame 2 is fitted around the ultra-thin shell of the backlight body 1. One side of the outer frame 2 has an opening corresponding to the wiring terminal 101 of the backlight body 1. The sealing strip 3 is positioned within the opening on one side of the outer frame 2. The sealing strip 3 is in a closed fit with the wiring terminal 101. Grooves 301 are respectively provided at both ends of the sealing strip 3, and abutment springs 5 are arranged within each groove 301. When squeezed, the abutment springs 5 can retract into the grooves 301 without affecting the sealing strip 3 being pushed into the opening on one side of the outer frame 2. The abutment springs 5 engage with the abutment grooves 201 formed on the inner wall of the opening side of the outer frame 2.
[0033] This utility model, by setting an outer frame 2, a seal 3, abutment spring 5 and abutment groove 201, has the advantage that when not in use for a long time, the seal 3 can be quickly inserted into the opening on one side of the outer frame 2 to seal the wiring terminal 101 and prevent dust from entering. It solves the problem that dust will enter the backlight when it is not used for a long time, and that dust at the plug will affect the connection.
[0034] Specifically, the abutment spring 5 has an arc-shaped structure design, with the arched end of the abutment spring 5 located outside the groove 301, and the arched end of the abutment spring 5 is adapted to the arc-shaped abutment groove 201. The arc-shaped abutment spring 5 bends better when squeezed, without affecting the sealing strip 3 being pushed into the opening on one side of the outer frame 2.
[0035] Furthermore, inserts 501 are provided at both ends of the abutting spring 5, and embedding grooves 302 are provided at the inner ends of the two side walls of the groove 301, and the inserts 501 and the embedding grooves 302 are inserted and engaged.
[0036] This utility model, by setting the insert 501 and the embedding groove 302, has the advantages of being able to replace the elastically failed abutment piece 5 and reusing the insert 501.
[0037] Furthermore, the outer side of the outer end of the insert 501 is designed as a slope 5011, and the area of the insertion end of the insert 501 is smaller than the area of the inlet port of the embedding groove 302. This makes it easier for the insertion end of the insert 501 to be inserted into the embedding groove 302.
[0038] It is worth noting that guide blocks 4 are fixed on the upper and lower sides of both ends of the seal 3, and the protruding end of the guide block 4 is matched with the opening end of the outer frame 2.
[0039] This utility model, by setting a guide block 4, has the advantage that when the seal 3 is pushed into the opening on one side of the outer frame 2, the guide block 4 contacts the upper and lower sides of the opening end of the outer frame 2 to guide it, so that the seal 3 can be pushed into the opening on one side of the outer frame 2 stably and accurately.
[0040] Working principle: Using the device of this utility model, when the backlight body 1 is not used for a long time, the sealing strip 3 is pushed into the opening on one side of the outer frame 2. The guide block 4 contacts the upper and lower sides of the opening end of the outer frame 2 to guide the pushed sealing strip 3. The sealing strip 3 is pushed in stably and accurately. During the pushing process, the arc-shaped abutment spring 5 is squeezed until the sealing strip 3 is completely pushed into the opening of the outer frame 2. After the arc-shaped abutment spring 5 rebounds, it abuts against the abutment groove 201, positioning the sealing strip 3 in the opening of the outer frame 2 and sealing the wiring terminal 101 to prevent dust from entering.
[0041] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
