Description
Technical field
The utility model relates to fingerprint identification device, particularly a kind of waterproof fingerprint identification device for mobile phone.
Background technology
At present, have three anti-mobile phones are with fingerprint recognition and compatible major key, if hand is moistening in use for user, water on hand likely infiltrates interior of mobile phone by the gap of key and handset front case and causes the situations such as short circuit.
Chinese patent (publication number CN 202523077U) discloses a kind of installation sleeve structure for laying fingerprint identification module, comprise installation sleeve, described installation sleeve is provided with the container cavity for placing fingerprint identification module, the fingerprint Identification sensor of the corresponding fingerprint identification module in container cavity front is provided with window, and the container cavity back side is opened wide.This kind of installation sleeve can make firm being arranged in container cavity of fingerprint identification module, and the corresponding fingerprint Identification sensor of installation sleeve offers window, and fingerprint Identification sensor extends in window, thus improves the discrimination to fingerprint.Water-proof rubber sleeve is provided with between described fingerprint Identification sensor and the window of container cavity, thus when avoiding the finger touch fingerprint Identification sensor of wet water, moisture content enters in container cavity through gap between fingerprint Identification sensor and window, to affect normal use and the life-span of fingerprint identification module.
Although this technical scheme can prevent moisture content from infiltrating, waterproof and structural design more complicated, need independent design waterproof construction nested.Fingerprint recognition and major key are made of one by the design also had, and are locked on fore shell, realize water-proof function with waterproof gum, and this design shortcoming is exactly complex procedures and cost is higher.
Utility model content
The technical problems to be solved in the utility model is to overcome prior art complex structure, defect that cost is higher, provides a kind of structure simpler and the waterproof fingerprint identification device for mobile phone that cost is lower.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of waterproof fingerprint identification device for mobile phone, it includes a fingerprint recognition module and a flexible PCB, described fingerprint recognition module is electrically connected with the mainboard of described flexible PCB and described mobile phone respectively, its feature is, described fingerprint recognition module is electrically connected with described flexible PCB by a connector;
The fore shell of mobile phone is provided with one for being installed with the first groove of described flexible PCB;
Described flexible PCB pads in described first groove to be located at immediately below described fingerprint recognition module;
Described fore shell is also provided with one for being installed with the second groove of described connector, fill out in described second groove and be provided with Waterproof glue line, described Waterproof glue line covers described connector.
Preferably, one is provided with in described first groove for wearing the through hole of connection line between described flexible PCB and described mainboard;
Marine glue point closes a side of the close described mainboard of described through hole.
Preferably, described flexible PCB is fixed in described first groove by marine glue.
Positive progressive effect of the present utility model is: stacked flexible PCB and the fingerprint recognition module of arranging is in the first groove, and the connector Waterproof glue line of the two is covered, make only to need to carry out simple change to the part-structure of fore shell can realize fingerprint identification device and possess water-proof function, reduce cost.

Fig. 1 is the explosive view of the waterproof fingerprint identification device for mobile phone of the present embodiment, Fig. 2 is the stereogram of the waterproof fingerprint identification device for mobile phone of the present embodiment, Fig. 3 is first groove of the present embodiment and the structural representation of the second groove, as shown in Figures 1 to 3, the waterproof fingerprint identification device for mobile phone that the present embodiment relates to includes fingerprint recognition module 5 and a flexible PCB 3, fingerprint recognition module 5 is connected with flexible PCB 3, the mainboard electrical connection of flexible PCB 3 and mobile phone, fingerprint recognition module 5 is electrically connected with flexible PCB 3 by connector 7.The fore shell 2 of mobile phone is provided with one for being installed with the first groove 4 of fingerprint recognition module 5 and flexible PCB 3.
The fore shell 2 of mobile phone is specification conventional in prior art, can be coordinated by fastener with the miscellaneous part of mobile phone body.In addition, mobile phone screen 1 also in a conventional manner with fore shell 2 split.
Flexible PCB 3 pads and is located at immediately below fingerprint recognition module 5 in the first groove 4.Fore shell 2 is also provided with one for be installed with connector 7 the second groove 6, second groove 6 in fill out and be provided with Waterproof glue line, Waterproof glue line covering connector 7.
Wherein, owing to also there being part circuit between the first groove 4 and the second groove 6, be therefore provided with connectivity slot 8 accordingly and be communicated with the first groove with the second groove and be installed with the circuit being connected connector and flexible PCB 3 (i.e. FPC plate).
One is provided with for wearing the through hole 9 of connection line between fingerprint recognition module 5 and mainboard in first groove 4.
Marine glue point closes a side (not shown) of the close mainboard of through hole 9.
Fingerprint recognition module 5 and flexible PCB 3 are fixed in the first groove 4 by marine glue, realize fixing by putting marine glue on four angles of square fingerprint recognition module 5 in the present embodiment, because fingerprint recognition module 5 is built on flexible PCB 3, therefore flexible PCB is also fixed.
In the present embodiment, what Waterproof glue line and the marine glue for shutoff through hole 9 adopted is nano-silicon marine glue, nano-silicon marine glue resistance to water, weatherability, excellent durability, and nontoxic, tasteless, environment friendly and pollution-free, and coating entirety is also without seam.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that this only illustrates, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
