Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that described embodiment is the utility model part of the embodiment, rather than whole implementation
Example.Based on the embodiment in the utility model, those of ordinary skill in the art are obtained under the premise of creative work is not made
The every other embodiment obtained, belong to the scope of the utility model protection.
The utility model embodiment provides a kind of sealing combination structure, as shown in Figure 3 and Figure 4, including：Body construction
301 and sealing structure 302, the sealing structure 302 be moulded in the outer surface of the body construction 301.Wherein, the body construction 1
For metal body structure or plastic body structure, sealing structure 2 is plastic cement sealing structure or silica gel sealing structure.
Specifically body construction 301 to be fixed on to position appropriate in injection mould for insert in advance, modeling is then reinjected
Glue or silica gel are simultaneously molded, and sealing structure 302 is cooled after die sinking solidifies and pack tightly above-mentioned body construction 301.
Above-mentioned insert injection moulding technology is applied in mobile terminal structure, can be that mobile terminal brings more benefits, such as
USB metal consents or the body construction outer surface of earphone socket in the terminal is molded one layer of sealing structure, it is possible to increase
The waterproof and anti-dust performance of USB socket or earphone socket, prevent liquid type or dust class material from passing through USB socket or earphone socket
Enter inside mobile terminal, corrode the internal components of mobile terminal.
As shown in Figure 3 and Figure 4, in the utility model embodiment, formed with multiple holes on the outer surface of body construction 301
3011, multiple small holes 3012 are formed on the inwall in each hole 3011；It is in sealing structure 302, outer with body construction 301
The one side of surface fitting is extended in the hole 3011 and small hole 3012, and embedding with the hole 3011 and small hole 3012
Close connection.So, the connection between body construction 301 and sealing structure 302 is just not limited only to the plane connection of horizontal direction, also
Aperture connection with vertical direction, can make to connect even closer between body construction 301 and sealing structure 302, extraneous
Liquid type or dust class material be difficult then that sealing group is entered by the gap between body construction 301 and sealing structure 302
The inside of mobile terminal where conjunction structure, so that the waterproof of sealing combination structure and anti-dust performance are more superior.It is in addition, logical
Cross and this some holes 3011 and small hole 3012 are set, moreover it is possible to increase the contact area of body construction 301 and sealing structure 302, carry
The firmness connected between high body construction 301 and sealing structure 302, the stabilizing quality of lift-off seal combining structure.
Further, in the utility model embodiment, the outer surface of body construction 301 is to carry out coarse PROCESS FOR TREATMENT
Rough surface, it is embodied in：Formed with multiple holes 3011 on the outer surface of body construction 301, on the inwall in each hole 3011
Form multiple small holes 3012.
Wherein, rough surface can effectively strengthen the adhesion between body construction 301 and sealing structure 302, therefore only
The sealing structure 302 that layer need to be molded in the outer surface of body construction 301 can meet the needs of bond strength, so as to
The enough thickness for effectively reducing sealing combination structure, advantageously realizes miniaturization and contracting in sealing combination structure (such as USB socket)
Macro, reduce the inner space for taking mobile terminal.
Wherein, the rough surface of body construction 301 is acid treatment surface, i.e. the rough surface of body construction 301 can pass through
Acid treatment is formed.In the specific implementation, the concentration and proportioning of acid solution are controlled, the outer surface of body construction is eroded, makes this
The outer surface of body structure 301 forms satisfactory hole 3011 and small hole 3012.In addition, the coarse table of body construction 301
Face can also be that frosted handles surface, i.e. the rough surface of body construction 301 can be formed by frosted processing or blasting treatment.One
As in the case of, this some holes 3011 and small hole 3012 are nanoscale structures, very small, will not cause body construction 301
Damage, do not interfere with the outward appearance of body construction 301 yet.
Wherein, this some holes 3011 in the utility model embodiment and small hole 3012 are generally irregular shape, when
Can also be so regular shape, specifically depending on the pore-forming technique taken.In the utility model embodiment, it is desirable to Mei Gekong
The span in 3011 aperture is 20nm~150nm, preferably 100nm~140nm；The aperture of each small hole 3012
Span is 20nm~60nm, preferably 25nm~40nm.
Further, in the utility model embodiment, body construction 301 is：USB socket or earphone socket etc..By
The outer surface of USB socket or earphone socket forms multiple micro holes formed with multiple holes 3011 again on the inwall in each hole 3011
Hole 3012 so that USB socket or earphone socket be connected with sealing structure 302 it is even closer, so, extraneous liquid type or
Dust class material is difficult then to enter USB socket or ear by the gap between USB socket or earphone socket and sealing structure 302
The inside of mobile terminal where machine transplanting of rice seat, so that the waterproof and anti-dust performance of USB socket or earphone socket structure are more excellent
More.
Further, in the utility model embodiment, sealing structure 302 is nanometer injection molding.
Nanometer injection refers to a nanometer forming technique (Nano Molding Technology), is metal with plastic cement with nanometer
The technique that technology combines, metal surface after nanosizing is handled, by plastic cement direct injection in metal surface, is being allowed into gold
Category and plastic cement can be not only able to take into account metal appearance texture, can also be simplified the design of product construction part with integrally formed, allow product
It is lighter, thin, short, small.
In summary, in the sealing combination structure that the utility model embodiment provides, shape on the outer surface of body construction 301
Into having multiple holes 3011, on the inwall in each hole 3011 and form the modes of multiple small holes 3012, this some holes 3011 with
It is even closer that small hole 3012 makes body construction 301 be connected with sealing structure 302, so as to improve the anti-of sealing combination structure
Water and anti-dust performance.
The utility model embodiment additionally provides a kind of mobile terminal, including：Seal combination described in above-described embodiment
Structure.
Sealing combination structure in the mobile terminal that the utility model embodiment provides, including body construction 301 and injection
Sealing structure 302 in the outer surface of body construction 301.Wherein, formed with multiple holes on the outer surface of body construction 301
3011, form multiple small holes 3012 again on the inwall in each hole 3011, sealing structure 302 is outer with body construction 301
The one side of surface fitting is extended in the hole 3011 and small hole 3012, and embedding with the hole 3011 and small hole 3012
Close connection.It is even closer that this some holes 3011 and small hole 3012 make body construction 301 be connected with sealing structure 302, so as to
The waterproof and anti-dust performance of sealing combination structure are improved, also further increases the waterproof and anti-dust performance of mobile terminal, favorably
Usage experience in lifting user to mobile terminal.
