Description
Technical field
This utility model relates to a kind of waterproof fingerprint module, belongs to technical field of semiconductor encapsulation.
Background technology
Along with the development of development of Mobile Internet technology, security issues become increasingly urgent for mobile Internet terminal user identification information, because of identity identification information is stolen and personation and cause the situation of user's economic loss to appear in the newspapers repeatly end.Conventional password formula identification scheme, also exists that efficiency length low, consuming time, safety be low and the problem such as complex operation, gradually becomes the short slab problem that the development of current development of Mobile Internet technology is universal.Fingerprint identification technology as the unique biological characteristic of user can efficiently solve the problems referred to above.
Prior art fingerprint module is as shown in Figure 1; cover plate 1 is placed in above fingerprint recognition chip 2; fingerprint recognition chip 2 can be protected; there is quoit 6 cover plate 1 side; internal clearance 8 is had between quoit 6 and cover plate 1; quoit 6 opposite side has protection sheet glass 3, has external series gap 9 between quoit 6 and protection sheet glass 3.Due to the existence of internal clearance 8 and external series gap 9, communication apparatus is easily immersed by liquid such as water, causing trouble.
Summary of the invention
This utility model purpose is to provide a kind of waterproof fingerprint module, this waterproof fingerprint module simplifying fingerprint modular structure, makes fingerprint module and protects glass and easily align, it is prevented that offset scrapes hands；Simultaneously, it is possible to play the effect of waterproof and dustproof, reduce fault, effectively protect equipment, thus extending service life.
For reaching above-mentioned purpose; the technical solution adopted in the utility model is: a kind of waterproof fingerprint module; including cover plate, fingerprint recognition chip, protection sheet glass and circuit board; described cover plate is positioned at directly over fingerprint recognition chip; described protection sheet glass has an installation through hole; described cover plate embeds in the installation through hole of protection sheet glass, is filled with glue layer in the gap between this cover plate side outer surface and protection sheet glass inner surface.
In technique scheme, further improved plan is as follows:
1., in such scheme, described installation shape of through holes is circular, square, oval or track type.
2., in such scheme, described cover plate is generally circular in shape, square, oval or track type.
3., in such scheme, described cover plate is sapphire cover plate, glass cover-plate or ceramic cover plate.
Owing to technique scheme is used, this utility model compared with prior art has following advantages and effect:
This utility model waterproof fingerprint module, which omits quoit, simplifies fingerprint modular structure, makes fingerprint module easily align with protection glass, it is prevented that offset scrapes hands；Meanwhile, it is filled with glue layer in the gap between cover plate side outer surface and protection sheet glass inner surface, it is possible to play the effect of waterproof and dustproof, reduce fault, effectively protect equipment, thus extending service life.

Accompanying drawing 2 is this utility model waterproof fingerprint modular structure schematic diagram.
In the figures above: 1, cover plate；2, fingerprint recognition chip；3, protection sheet glass；31, through hole is installed；4, circuit board；5, glue layer；6, quoit；7, gap；8, internal clearance；9, external series gap.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is further described:
Embodiment 1: a kind of waterproof fingerprint module; including cover plate 1, fingerprint recognition chip 2, protection sheet glass 3 and circuit board 4; described cover plate 1 is positioned at directly over fingerprint recognition chip 2; described protection sheet glass 3 has an installation through hole 31; described cover plate 1 embeds in the installation through hole 31 of protection sheet glass 3, is filled with glue layer 5 in the gap 7 between this cover plate 1 side outer surface and protection sheet glass 3 inner surface.
Above-mentioned installation through hole 31 is shaped as ellipse.Above-mentioned cover plate 1 is shaped as ellipse.Above-mentioned cover plate 1 is glass cover-plate.
Embodiment 2: a kind of waterproof fingerprint module; including cover plate 1, fingerprint recognition chip 2, protection sheet glass 3 and circuit board 4; described cover plate 1 is positioned at directly over fingerprint recognition chip 2; described protection sheet glass 3 has an installation through hole 31; described cover plate 1 embeds in the installation through hole 31 of protection sheet glass 3, is filled with glue layer 5 in the gap 7 between this cover plate 1 side outer surface and protection sheet glass 3 inner surface.
Above-mentioned installation through hole 31 is generally circular in shape.Above-mentioned cover plate 1 is generally circular in shape.Above-mentioned cover plate 1 is sapphire cover plate.
When adopting above-mentioned waterproof fingerprint module, which omits quoit, simplify fingerprint modular structure, make fingerprint module easily align with protection glass, it is prevented that offset scrapes hands；Meanwhile, it is filled with glue layer in the gap between cover plate side outer surface and protection sheet glass inner surface, it is possible to play the effect of waterproof and dustproof, reduce fault, effectively protect equipment, thus extending service life.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this.All equivalences made according to this utility model spirit change or modify, and all should be encompassed within protection domain of the present utility model.
