Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
This utility model embodiment provides a kind of waterproof fingerprint recognition module, as Figure 1-Figure 5, including fingerprint recognition key
Cap 01, fpc02, fingerprint recognition keycap 01 is fixed on fpc02, and fingerprint recognition keycap 01 bottom surface contacted with fpc02 is provided with
Groove 11, is provided with fluid sealant 03 in groove 11.
The waterproof fingerprint recognition module that this utility model embodiment provides, because at the fingerprint recognition keycap contacted with fpc
Bottom surface is provided with groove, and is provided with fluid sealant in a groove, and therefore the space between fingerprint recognition keycap and fpc can be passed through
Fluid sealant seals, and is thus possible to prevent the conducting liquids such as water to immerse solder joint, causes short circuit.So just can reach relatively
Good waterproof effect.
Further, groove 11 is the groove along fingerprint recognition keycap 01 1 circle, groove 11 shape and fingerprint recognition keycap
01 shape is consistent.So, fingerprint recognition keycap 01 bottom surface contacted with fpc arranges a circle groove, and sets in a groove
Put fluid sealant, so that the gap that contacts with fpc of fingerprint recognition keycap 01 is filled with fluid sealant, thus stop water
Enter on fpc by these gaps, cause fpc short circuit, well protect fpc.
Specifically, by mode for dispensing glue, glue can be filled in groove 11, because glue has mobility, so
May be in irregular shape after glue curing, so by the regular shape of glue by the way of mould is die-cut.Fpc can set
That puts is larger than fingerprint recognition keycap 01, and wherein, Fig. 1 and Fig. 2 is two of the most die-cut front waterproof fingerprint recognition module and cuts open
Face structural representation, at this moment, it is larger than fingerprint recognition keycap that fpc is arranged.So, mould is die-cut when, can be by
Glue is die-cut together with fpc, in order to both regular shape, keeps consistent.Wherein, Fig. 4-Fig. 5 be carry out mould die-cut after
The cross-sectional view of two angles of waterproof fingerprint recognition module.
Further, as it is shown on figure 3, fingerprint recognition keycap 01 bottom surface is provided with protruding 12, protruding 12 for being known by fingerprint
Other keycap 01 is fixed in casing.So so that fingerprint recognition keycap is well fixed in casing by protruding 12, anti-
Only fingerprint recognition keycap 01 is run out of from casing, and this mode realizes simply, and cost is relatively low.
Specifically, projection can be designed as shirt rim, and has the circular arc shirt rim consistent with keycap two ends circular arc, with side
Will pass through shirt rim to be fixed in casing by fingerprint recognition keycap 01.
It should be understood that the embodiment of the present invention is not limited to this shape, protruding shape and pattern can also be
Other shapes, as long as the effect being fixed in casing by fingerprint recognition keycap 01 can be played.
Further, protruding 12 is two, lays respectively at fingerprint recognition keycap 01 two ends.This fixed form is more firm
Gu, and be easily achieved.
It should be understood that the protruding quantity in the embodiment of the present invention is also not limited to 2, it is also possible to for multiple,
As long as the effect being fixed in casing by fingerprint recognition keycap 01 can be played.
Further, also include that strengthening course 04, fpc02 another side are fixed on strengthening course 04.Strengthening course 04 acts primarily as benefit
Strong effect, plays a supporting role to fpc, is used for protecting fpc.
Strengthening course 04 can use metal material to make, and specifically can also make of steel disc.
It should be understood that the embodiment of the present invention is not limited to metal material to the material of strengthening course 04, as long as permissible
Play and support the material of strengthening action all within protection scope of the present invention.
Further, also include that conductive base 05, conductive base 05 are fixed on the back side of strengthening course 04.
On the other hand, this utility model embodiment also provides for a kind of waterproof mobile terminal, including above-mentioned waterproof fingerprint recognition
Module.
Wherein, Fig. 6 is the waterproof fingerprint recognition module in waterproof mobile terminal and fixing structure for machine shell schematic diagram, such as Fig. 6
Shown in, waterproof fingerprint recognition module 1 is fixed in casing 2 by the projection 12 arranged on fingerprint recognition keycap.In casing 2
Being correspondingly arranged fluted (not shown), groove coordinates so that waterproof fingerprint recognition module and casing are fixed on one with protruding 12
Rise.
Wherein, the quantity of groove keeps consistent with protruding quantity, in order to preferably both be fixed together.
The waterproof mobile terminal that this utility model embodiment provides, because in the fingerprint recognition keycap bottom surface contacted with fpc
Being provided with groove, and be provided with fluid sealant in a groove, therefore the space between fingerprint recognition keycap and fpc can be by sealing
Glue seals, and is thus possible to prevent the conducting liquids such as water to immerse solder joint, causes short circuit.So just can reach preferable
Waterproof effect.
The above, detailed description of the invention the most of the present utility model, but protection domain of the present utility model does not limit to
In this, any those familiar with the art, in the technical scope that this utility model discloses, can readily occur in change
Or replace, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with described power
The protection domain that profit requires is as the criterion.
