Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides the following technical solutions: an explosion-proof and pressure-resistant mobile phone backlight source comprises a rubber frame 1 and a backlight source body 10, wherein the backlight source body 10 is arranged inside the rubber frame 1, an embedding groove 2 is arranged on the inner wall of the rubber frame 1, grooves 4 are uniformly arranged at the bottom inside the embedding grooves 2 on two sides, and the inner parts of the two side caulking grooves 2 are respectively provided with a clamping plate 3, one side of the clamping plate 3 departing from the backlight source body 10 is uniformly fixed with a buffer spring 8, and the splint 3 is provided with a bracket 11 facing the backlight body 10, specifically, the backlight body 10 is clamped from both sides by the movable splint 3 provided with the bracket 11, when the backlight body 10 is pressed from both sides, the buffer spring 8 embedded in the groove 4 and connected with the clamping plate 3 is compressed and contracted, the generated elastic force can effectively buffer the pressure, further, the backlight body 10 can be effectively protected, the backlight body is prevented from being burst and damaged due to pressure, and the service life of the backlight body 10 is prolonged.
