The mobile terminal structure schematic diagram that Fig. 1-3 is provided by the embodiment of the present invention, the present invention provide a kind of mobile terminal,
Including casing 10, flexible PCB 20 and water repellent component 30.Specifically, casing 10 realizes branch to the electronic component in mobile terminal
It supports and fixed.Flexible PCB 20 completes signal transmission for realizing the electrical connection between each electronic component.Flexible PCB
20 are arranged between casing 10, and the electronic component inside and outside casing 10 is electrically connected to realize electric signal
Therefore water repellent component need to be arranged to prevent junction of 10 external streams of casing through casing 10 and flexible PCB 20 from flowing in transmission
Enter to casing 10, and then the electronic component inside casing 10 is damaged.
In the present embodiment, it refers to shown in Fig. 1,4 and 5, water repellent component 30 includes support base 31 and fixed plate 32.Its
In, to realize that the receiving to water repellent component 30 is assembled, groove 11, the flexibility being connected with water repellent component 30 are set on casing 10
Circuit board 20 is arranged in groove 11, is provided with limit protrusion 12 in groove 11, in 31 assembling groove 11 of support base and is connected to
The limit and supporting role for support base 31 are realized in the surface of limit protrusion 12 by limit protrusion 12.Groove 11 for realizing
Receiving assembly to water repellent component 30 and flexible PCB 20, so that flexible PCB 20 is stretched to through groove 11 positioned at casing 10
It is internal.It optionally in limit protrusion 12 and is supported for the Assembly stability for further improving between support base 31 and casing 10
It is coated with bonded adhesives between seat 31.Optionally, to improve the support strength of support base 31 and fixed plate 32, fixed plate 32 is PET materials
Matter, support base 31 are PC materials.
It refers to shown in Fig. 3 and 4, is arranged with sealing ring 33 on support base 31, the side of sealing ring 33 and support base 31 is equal
It is connected to limit protrusion 12, the limit and support to sealing ring 33 and support base 31 are realized by limit protrusion 12.33 sets of sealing ring
Set on the outer rim of support base 31, the side wall of support base 31 and groove 11 is fitted in inside and outside sealing ring 33 respectively.By sealing
Circle 33 and support base 31 prevent the liquid stream being located at outside casing 10 from being flowed into inside casing 10 through groove 11.Wherein, sealing ring 33
It is elastic conjunction between groove 11.Through-hole 311 is opened up on support base 31, through-hole 311 is for so that flexible PCB 20 is worn
Inside support base 31, the transmission of the electric signal inside and outside casing 10 is completed.
Fixed plate 32 is fixedly installed on the side of support base 31, that is to say, that fitting to fix with 31 side of support base sets
The fixed plate 32 set is connected to one end of through-hole 311, and is collectively formed by fixed plate 32, through-hole 311 and groove 11 for accommodating
The space of flexible PCB 20.Grooving 321 is opened up in fixed plate 32, flexible PCB 20 enters to logical through opened up grooving 321
In hole 311 and groove 11.
Specifically, grooving 321 is extended along the width direction of flexible PCB 20, and grooving 321 is along flexible circuit
Size in the width direction of plate 20（That is length dimension）More than the width dimensions of flexible PCB 20, so that flexible PCB
20 directions through grooving 321 towards limit protrusion 12 are stretched out.Wherein, it refers to shown in Fig. 2 and 5, the width of flexible PCB 20
Degree direction refers to the A in Fig. 2 and 5 to shown.
It is assembled through grooving 321 and fixed plate 32 for convenience of flexible PCB 20, one end of grooving 321 extends to fixation
The end of plate 32, and then the opening being connected with grooving 321 is formed in the outer rim of fixed plate 32 so that flexible PCB 20 passes through
Opening is assemblied in along the width direction of flexible PCB 20 in grooving 321.
To ensure flexible PCB 20 through the stretching of grooving 321 and flexible PCB 20 being avoided to be assembled at grooving 321
It scrapes and squeezes, the width dimensions of the grooving 321 opened up are more than the thickness of flexible PCB 20, wherein please refer to Fig. 2
Shown in 5, the width dimensions of grooving 321 refer to along B to being opened up.Flexible PCB 20 is contained in through grooving 321 by fixed plate
32 and through-hole 311 enclose and set in the accommodation space to be formed.
Optionally, fixed plate 32 can pass through the side of double faced adhesive tape and support base 31（That is the end face of support base 31）It is connected,
It sets to form the accommodation space for accommodating flexible PCB 20 so that fixed plate 32 is enclosed jointly with the through-hole 311 in support base 31.
To further increase the connective stability of fixed plate 32 and support base 31, can through-hole 311 and fixed plate 32 abut against place into
Row dispensing, so improve support base 31 and fixed plate 32 connective stability, further, via through holes 311 to be connected to support
32 dispensing of fixed plate of the side of seat 31, it is ensured that activity space for dispensing glue facilitates dispensing to operate, and then ensures that dispensing is coated with effect
Fruit and connective stability.Furthermore it is attached fixation in the side of fixed plate 32 and support base 31, or in fixed plate 32 and through-hole
311 junction carries out dispensing and fixes, and then realizes that the single side in fixed plate 32 is fixed, sizing material after preventing dispensing from completing
From the another side excessive glue outflow of fixed plate 32, ensure Assembly stability and assembling quality.
To prevent the fit-up gap of the liquid stream through flexible PCB 20 and grooving 321 in 10 outside of casing from flowing into casing 10
It is interior, cause the electronic component being laid on flexible PCB 20 or inside casing 10 to damage, flexible PCB 20 with cut
The fit-up gap of slot 321 is filled with fluid sealant.
In embodiments of the present invention, by limit protrusion 12 on casing 10, be assemblied in groove 11 and support base 31 it
Between sealing ring 33, fixed plate 32 jointly realize prevent the liquid stream inside and outside casing 10 from fleeing, realize to flexible PCB 20
With waterproof efficacy of the casing 10 at assembly, ensure the water resistance of mobile terminal.On the other hand, it is sheathed on flexible PCB 20
On water repellent component 30 by being detachably connected with the groove 11 on casing 10, facilitate and torn open between flexible PCB 20 and casing 10
It unloads and maintenance operation.
