The applicable property of other techniques and/or the use of other materials.
The fingerprint sensing component for terminal of embodiment according to a first aspect of the present invention is described below with reference to Fig. 1-Fig. 3.
As shown in Fig. 2, the fingerprint sensing component for terminal of embodiment according to a first aspect of the present invention, including：Decoration
Ring 1, fingerprint chip 2 and fluid sealant 3.
Specifically, as shown in Figure 1, the inner ring of rosette 1 limits mounting hole 12, inside the adjacent terminals of rosette 1
There is first annular groove 11, the internal perisporium of first annular groove 11 is (i.e. neighbouring on one side end face (such as inner face shown in Fig. 2)
The perisporium of first annular 11 central axis of groove) opened wide towards mounting hole 12, in other words, internal perisporium is not present in first annular groove 11,
Fingerprint chip 2 is assemblied in mounting hole 12, a side end face inside the adjacent terminals of fingerprint chip 2 (such as it is interior shown in Fig. 2
End face) on there is the second annular groove 21, the periphery wall (week i.e. away from 21 central axis of the second annular groove of the second annular groove 21
Wall) opened wide towards mounting hole 12, in other words, periphery wall, the second annular groove 21 and first annular groove is not present in the second annular groove 21
11 connect to limit annular glue groove jointly.
With reference to Fig. 2 and Fig. 3, fluid sealant 3 is filled in annular glue groove to seal the ring between mounting hole 12 and fingerprint chip 2
Shape gap B, that is to say, that can be by fluid sealant 3 (such as common glue or solidification glue etc.) point in annular glue groove, and ensure
Fluid sealant 3 is full along the circumferential filling of annular glue groove, so that at least by the annular gap B's between mounting hole 12 and fingerprint chip 2
Inner (one end inside adjacent terminals) sealing, thus, positioned at side (the i.e. fingerprint core of the remote terminal inner of fingerprint chip 2
The outside of piece 2) liquid under the barrier effect of fluid sealant 3, it is impossible to the annular gap along between mounting hole 12 and fingerprint chip 2
B flows to the inner side of fingerprint chip 2, so as to avoid the inner leg of liquid corrosion fingerprint chip 2, cause asking for leg short-circuit failure
Topic, and then ensure that fingerprint chip 2 can be with reliably working.
Fingerprint sensing component for terminal according to embodiments of the present invention, by dividing on rosette 1 and fingerprint chip 2
First annular 11 and second annular groove 21 of groove is not processed, to reserve for annular glue groove for dispensing glue, so as in annular glue groove
Interior dot encapsulation glue 3 seals, and then prevents liquid from entering the inner side of fingerprint chip 2, prevents the weldering of the inner side of liquid corrosion fingerprint chip 2
The problem of foot causes fingerprint chip 2 to fail, reaches the final purpose of protection fingerprint chip 2.In addition, by setting annular glue groove simultaneously
Mode for dispensing glue is coordinated to play sealing waterproof action, so as to be effectively reduced the processing of rosette 1 and fingerprint chip 2 and dress
With difficulty, the structure complexity and production cost of fingerprint sensing component are reduced so that the structure of fingerprint sensing component is compacter,
It is exquisite.
In one embodiment of the invention, on the central axis of mounting hole 12, along from the outside of terminal to terminal
Inside direction, the cross-sectional area of mounting hole 12 gradually increases (not shown), and fingerprint chip 2 is formed as and 12 shape of mounting hole
Shape that shape is adapted and it is assemblied in mounting hole 12, thus, rosette 1 can realize that zero clearance is assembled with fingerprint chip 2, from
And the waterproof effect of fingerprint sensing component is further improved, improve the reliability of fingerprint sensing component operation.
In one embodiment of the invention, with reference to Fig. 1 and Fig. 3, the second annular groove 21 by fingerprint chip 2 adjacent terminals
The neighboring of an internal side end face (inner face i.e. shown in Fig. 1) is along the 2A (central axis of i.e. remote second annular groove 21
Edge) be directed away from direction (outside i.e. shown in Fig. 1) recessed formation of terminal.That is, the second annular groove 21 by
The inner neighboring of fingerprint chip 2 is outwardly concaved to be formed along 2A.Thus, the second annular groove 21 is convenient processes, and facilitates dispensing,
Sealing reliability higher for dispensing glue.
Further, with reference to Fig. 1 and Fig. 3, first annular groove 11 is by the side end face inside the adjacent terminals of rosette 1
The inner rim of (inner face i.e. shown in Fig. 1) is directed away from along 1A (edge of the central axis of i.e. neighbouring first annular groove 11)
Direction (outside i.e. shown in Fig. 1) recessed formation of terminal.That is, first annular groove 11 is by the inner of rosette 1
Inner rim is outwardly concaved to be formed along 1A.Thus, first annular groove 11 is convenient processes, and 11 and second annular groove 21 of first annular groove
Connect relatively reliable, more convenient dispensing, sealing reliability higher for dispensing glue.
Preferably, with reference to Fig. 3, bottom wall 21A (the side wall away from terminal inner) and the first ring of the second annular groove 21
The bottom wall 11A (the side wall away from terminal inner) of shape groove 11 is concordant.Thus, dispensing effect is more preferable, waterproof reliability higher.
Further, with reference to Fig. 3, the section of annular glue groove can be rectangle or trapezoidal.Thus, first annular 11 and second annular groove of groove
21 easily facilitate processing, and sealing reliability is more preferable.In some other embodiments of the present invention, the section of annular glue groove
It may be formed as triangle, semicircle or half elliptic etc..Thus, it is same easy to process and fluid sealant 3 can be saved, reduce
Production cost.Here, it is necessary to which explanation, section are referred to along the section obtained by the radial direction truncated annulus glue groove of annular glue groove.
In some embodiments of the present invention, along the extending direction of annular glue groove, i.e., along the circumferential direction of annular glue groove, the section of annular glue groove
Shape and size are identical everywhere, and thus, sealing effect is more preferable, and annular glue groove easily facilitates processing.
The terminal of embodiment according to a second aspect of the present invention is described below.Wherein, terminal can be fixed terminal or shifting
Dynamic terminal, wherein, fixed terminal can be desktop computer, and mobile terminal can be mobile phone, tablet computer or vehicle-mounted computer etc..Under
Face, only illustrates so that terminal is mobile phone as an example, after those skilled in the art have read following technical solution, it is clear that Ke Yili
