Contact area between shell and sealing ring increases sealing area between front housing and sealing ring, effectively improves waterproof performance.
As shown in figure 3, in the present embodiment, the amount of interference of waterproof foam 50 and rear shell 10 is 0.1mm, i.e. waterproof foam 50
Thickness be greater than the distance between rear shell 10 and connector 30 0.1mm, the thickness of sealing ring 40 is equal to rear shell 10 and connector 30
The distance between.For example, waterproof foam 50 with a thickness of 0.4mm, the distance between rear shell 10 and connector 30 are 0.3mm, close
The thickness 0.3mm of seal 40.
As shown in figure 4, sealing ring 40 includes: fixed part 41 and multiple annulars in one embodiment of the application
Sealing 42.
Fixed part 41 is set on the port of connector 30.
Multiple sealings 42 are arranged on fixed part 41, and are tightly connected respectively with front housing 20 and rear shell 10.
In this embodiment, the sealing 42 Yu front housing 20 of multiple annulars and the multiple waterproofs of formation in sealing contact of rear shell 10
Circle, when sealing 42 on the outermost side is because of aging or damage failure, other sealings 42 still can be realized waterproof action,
So as to improve the waterproof effect of sealing ring 40.Specifically, liquid by sealing on the outermost side 42 and front housing 20 and
Between rear shell 10 behind gap, since other sealings 42 are still tightly connected with front housing 20 and rear shell 10, liquid cannot pass through
The sealing 42, ensure that the waterproof effect of sealing ring 40.
In one embodiment of the application, the surface of sealing ring 40 is rough surface.The cooperation of rear shell 10 and sealing ring 40
Face is rough surface.The mating surface of front housing 20 and sealing ring 40 is rough surface.On the one hand, can increase sealing ring 40 and front housing 20 and
Frictional force between rear shell 10 prevents movement of the sealing ring 40 in use relative to front housing 20 and rear shell 10, so as to
Enough guarantee the reliability that sealing ring 40 uses.On the other hand, the microstructure of rough surface is the injustice with peak valley and protrusion 31
Face, the rough surface peak valley of sealing ring 40 and the protrusion 31 of mating surface cooperate, rough surface protrusion 31 and the mating surface of sealing ring 40
Peak valley cooperation, makes to form occlusion structure between sealing ring 40 and front housing 20 and rear shell 10, so as to increase sealing ring 40 with before
Leakproofness between shell 20 and rear shell 10, can be effectively prevented the entrance of liquid, and then can be improved the waterproofness of product.
As shown in figure 4, in one embodiment of the application, the thickness of sealing ring 40 be greater than front housing 20 and connector 30 it
Between distance.
In this embodiment, make sealing ring since the thickness of sealing ring 40 is greater than the distance between front housing 20 and connector 30
