Specific embodiment
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below in conjunction with this reality
With the attached drawing in new embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that
The described embodiments are only a part of the embodiments of the utility model, instead of all the embodiments.Based on the utility model
In embodiment, those of ordinary skill in the art's every other implementation obtained without making creative work
Example, fall within the protection scope of the utility model.
Embodiment one
The utility model embodiment provides a kind of electrostatic protection apparatus, is applied to terminal.Fig. 1 is the utility model implementation
A kind of structural schematic diagram one for electrostatic protection apparatus that example provides.As shown in Figure 1, the electrostatic protection apparatus 1 includes:
Cosmetic sheet 10 and grounding elastic slice 11, cosmetic sheet 10 are arranged around the camera 12 of terminal, and the first of grounding elastic slice 11
End 110 is contacted with cosmetic sheet 10, and second end 111 is connect with grounding point；Wherein, 10 surface of cosmetic sheet is covered with insulating layer, insulation
The thickness of layer is greater than the first preset threshold, and the shortest distance less than the second preset threshold, between cosmetic sheet 10 and camera 12
Greater than third predetermined threshold value.
It should be noted that cosmetic sheet 10 is made of metal material in the utility model embodiment, specific metal material
Material the utility model embodiment is not construed as limiting.
It should be noted that 10 surface of cosmetic sheet carried out insulation processing in advance in the utility model embodiment, thus
It is covered with insulating layer on 10 surface of cosmetic sheet, also, the thickness of insulating layer is limited, and needs to meet certain condition, that is,
The thickness of insulating layer is greater than the first preset threshold, and less than the second preset threshold.Insulation processing specifically is carried out to cosmetic sheet 10
Method the utility model embodiment is not construed as limiting.
Illustratively, in the utility model embodiment, insulated paint is sprayed to 10 surface of cosmetic sheet in advance, the insulation sprayed
It paints thickness and is greater than the first preset threshold, and less than the second preset threshold.
It should be noted that the shortest distance between cosmetic sheet 10 and camera 12 needs in the utility model embodiment
It meets some requirements, i.e., the shortest distance between cosmetic sheet 10 and camera 12 is greater than third predetermined threshold value.
Illustratively, in the utility model embodiment, third predetermined threshold value 0.1cm, then cosmetic sheet 10 and camera
The shortest distance between 12 is greater than 0.1cm.
It should be noted that it is pre- that the thickness of 10 surface insulation layer of cosmetic sheet is greater than first in the utility model embodiment
If threshold value, and less than the second preset threshold, the shortest distance between cosmetic sheet 10 and camera 12 is greater than third predetermined threshold value, can
So that cosmetic sheet 10 is not turned on over the ground after electrostatic gets to cosmetic sheet 10, the power of the antenna of terminal configuration is not had an impact, and
And for electrostatic, it is easy to directly climb on camera 12 across the insulating layer of cosmetic sheet 10, that is, releasing electrostatic
Path clustering is the insulating layer across cosmetic sheet 10, is directed on the ground by grounding elastic slice 13, avoids electrostatic and directly climb to camera shooting
First 12, interference is generated to camera 12.Specific first preset threshold, the second preset threshold and third predetermined threshold value sheet are practical new
Type embodiment is not construed as limiting.

Threshold value needs to be configured according to the specific material of cosmetic sheet 10 and insulating layer, and different materials is default there are different first
The value of threshold value, the second preset threshold and third predetermined threshold value.
Illustratively, in the utility model embodiment, 10 surface insulation layer of cosmetic sheet with a thickness of H1, cosmetic sheet 10 with
The distance between camera 12 is H2, and the first preset threshold is A1, and the second preset threshold is A2, third predetermined threshold value A3, H1
Greater than A1 and it is less than A2, H2 is greater than A3.After electrostatic gets to cosmetic sheet 10, although cosmetic sheet 10 is connect with grounding elastic slice 13,
But since there is the insulating layer with a thickness of H1 on surface, also can not just be connected over the ground, therefore, the efficiency of terminal antenna will not generate
Interference.Also, electrostatic pass through with a thickness of H1 insulating layer than being directly easier by the camera 12 that air climbs to distance H2, it is quiet
Electricity is directed at directly through the insulating layer with a thickness of H1 in grounding elastic slice 11, is led on the ground by grounding elastic slice 11.
It is understood that in the prior art, not carrying out insulation processing to cosmetic sheet surface, therefore, cosmetic sheet is such as
Fruit is directly grounded, although electrostatic can be guided, largely influences whether the efficiency of terminal antenna, and if taking the photograph
As copper foil is sticked in head front, draw to electrostatic is guided on shielding case, productibility is poor, is easy to keep camera eccentric, generates matter
Amount problem.That is, can be guided without a kind of preferable method in the case where not increasing production difficulty in the prior art
The electrostatic of cosmetic sheet, and the efficiency of antenna can not be influenced.And in the utility model embodiment, it is pre- to 10 surface of cosmetic sheet
