Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the application is described in more detail.
The mobile terminal of the button with fingerprint that the application proposes, as it is shown in figure 1, include the plate end connection 16 that fingerprint recognition button 11 is electrically connected with governor circuit by bonded flexible PCB 12, sealing member 14, housing 15, governor circuit (not shown) and with fingerprint recognition.
As in figure 2 it is shown, fingerprint recognition button 11 is connected to one end of flexible PCB 12, the other end of flexible PCB 12 is pasted with a PCB 13 electrically connected with flexible PCB；The first adapter 131 it is pasted with in PCB 13.Visible, above-mentioned constituted a kind of Rigid Flex by fingerprint recognition button 11, flexible PCB 12 and PCB 13.
Offering the first perforate 151 on housing 15, sealing member 14 offers the second perforate 141, one end of plate end connection 16 is pasted with the second adapter 161；Sealing member 14 is placed in outside housing 15, and plate end connection 16 is placed in inside housing 15；First adapter 131 fastens through the second perforate 141 in the first perforate 151 and sealing member 14 with the second adapter 161 on plate end connection 16.
Above-mentioned, the housing shown in figure is the side body of the side body of mobile terminal, such as mobile phone, PAD etc., and accordingly, fingerprint recognition button 11 is then the side button of mobile terminal；Certainly, the embodiment of the present application does not limits for the installation site of fingerprint recognition button, can be fore shell and face-key, it is also possible to be back cover and back side button etc..
In this case, as shown in Figure 1, connecting has the Rigid Flex of fingerprint recognition button 11 to be arranged on outside housing 15, governor circuit and plate end connection 16 are arranged on the inner side of housing 15, during assembling, the sealing member 14 of such as foam rubber is placed on outside housing 15, Rigid Flex is attached at foam rubber 14 assemble, make overlapping with on housing 5, the first adapter 131 is made to enter inside housing 15 through the second perforate 141 and the first perforate 151, fasten with the second adapter 161 on the plate end connection 16 inside housing 15, thus realize the electrical connection of fingerprint recognition button and governor circuit, hardware foundation is provided for realizing fingerprint identification function.
For simplifying the assembling of mobile terminal, it is also possible to adhering in PCB 13 by sealing member 14 in advance, the first adapter 131 passes from the second perforate 141；During assembling, only the Rigid Flex having attached sealing member need to be installed on hull outside so that it is internal that the first adapter 131 stretches into housing 15 through the first perforate 151 on housing 15, fastens with the second adapter 161 on enclosure interior plate end connection 16.
Owing to the PCB 13 in Rigid Flex is hard circuit board, housing 15 is also hard material device, therefore, the sealing member 14 increased between PCB 13 and 15 two hard materials of housing, can firmly be clipped between PCB 13 and housing 15, well realize the sealing effectiveness in structure, the damage of sealing will not be caused because of the flexible generation deformation of structural member.The preferred foam rubber of sealing member.
Design through the structure of housing compared to flexible PCB in prior art, in this case, it is connected one end at flexible PCB 12 with housing and mounts PCB 13, using PCB 13 as signal transfer device, make flexible PCB not directly through housing, but passed housing by PCB with the form of adapter, on the basis of solid structure part, increase sealing member realize sealing structure, solid structure part will not produce deformation as flexible PCB, also sealing would not be caused damage, when solving existing mobile terminal employing fingerprint identification technology, with fingerprint recognition by bonded FPC softer and cannot the technical problem of sealing intact with casing.
And, in this case, in the case of ensureing that sealing member is assemblied between Rigid Flex and housing, the Rigid Flex of hull outside only need to realize assembling by the fastening of the first adapter and the second adapter with the plate end connection of enclosure interior, installation step is simple, play the effect reducing assembling procedure raising assembling work efficiency, and the error assembled is little.
As shown in Figure 3, a kind of decision design for plate end connection 16, the main body of this plate end connection 16 is the second flexible PCB 163, and the second adapter 161 uses SMT(Surface Mount Technology, surface mount process) technique is mounted on a side of the 163 of the second flexible PCB；And it is pasted with the 3rd adapter 162 with another side mounting the second adapter 161 opposite face on this second flexible PCB 163；Visible, the 3rd adapter 162 is mounted on the different sides on the second flexible PCB 163 two sides respectively from the second adapter 161.The circuit board of governor circuit is provided with the 4th adapter, the 3rd adapter and the 4th adapter and fastens the electrical connection realizing plate end connection 16 with governor circuit.In diagram, the second flexible PCB is bent as L-type, and dextrorotation turn 90 degrees use.
The mobile terminal of the button with fingerprint that the application proposes, as a example by mobile phone, when user uses fingerprint identification function, finger pressing fingerprint recognition button, this fingerprint recognition button such as fingerprint inductor, obtain user fingerprints information, be transferred to governor circuit via flexible PCB, PCB, the first adapter, the connection of the second adapter, governor circuit realize fingerprint recognition correlation function.Sealing member between fingerprint recognition button and housing can firmly be clamped between PCB and housing, and the first perforate through the first adapter is played the effect of sealing, and the fingerprint recognition button of whole mobile terminal is played the effect that sealing is waterproof.
It should be noted that; described above is not to restriction of the present utility model; this utility model is also not limited to the example above; change that those skilled in the art are made in essential scope of the present utility model, retrofit, add or replace, also should belong to protection domain of the present utility model.
