Electromechanical source key；[06] it is mobile phone volume key.
As it can be seen that in the prior art, the side housing of mobile phone is necessarily designed to metal shell so that the design cost of mobile phone increases
Add, for the pressure of cost, during by electronic device design into non-metal shell, resulting in fingerprint module ground connection becomes problem.For
Solve the problems, such as this, the utility model embodiment is changing the deployed position of current fingerprint chip, that is, is deployed in electronics
The side of equipment, also changes the structure of current fingerprint module, that is, removes the metal steel disc in fingerprint module.It is primarily due to electronics
The side of equipment is relatively narrow and space is limited, and the metal steel disc in fingerprint module is relatively thick, can influence overall group of electronic equipment
Dress.Meanwhile the utility model embodiment is replaced using the grounding scheme shown in Fig. 3 by using an electrostatic protection component
Metal steel disc, discharges so that the electrostatic on fingerprint chip is directed on circuit main board.
Specifically, by taking mobile phone as an example, the section schematic diagram for the electronic equipment that the utility model embodiment provides, such as Fig. 5 institutes
Show, in Figure 5, [201] are the side housings of mobile phone, and due to using new earthing mode, to side housing material, whether metal does not have
Require.[202] be mobile phone front housing；[203] be mobile phone SIM card/TF card device.[204] be mobile phone fingerprint mould
Group, the becket that fingerprint module body whether there is antistatic do not require.[05] it is cellular phone power supplies key.[206] it is mobile phone volume key.
[207] it is mobile fingerprint module earthing metal ring；[208] be mobile phone LCM；[209] be mobile phone TP.[210] it is mobile phone
Mainboard, mainboard are grounded that conversion shrapnel sticking area leakage copper is convenient and shrapnel earth-continuity in fingerprint module.[211] it is mobile fingerprint
Module ground connection switching shrapnel, shrapnel one end are pressed onto on [207] mobile fingerprint module earthing metal ring, and another side passes through conductive gluing
(mainboard leaks copper in this region) is attached on [210] mainboard, is fixed to finally by [214] mobile phone screw in complete machine.[212] it is glue
Water, is mainly used to fix [204] and [207], prevents two pieces from loosening.[214] it is mobile phone gum, is mainly used to fix Mobile phone screen
Cover, may be otherwise and fixed with glue dispensing.
Wherein, [213] are mobile phone screws, are mainly used to [211] being locked onto [210] cell phone mainboard.Mobile phone spiral shell
The fixed position front schematic view as shown in Figure 6 of silk.
From Fig. 5 and Fig. 6 as it can be seen that fingerprint chip is deployed in the side of electronic equipment, side can use it is nonmetallic can be with, from
And complete machine cost reduction is very much.In addition, fingerprint can be efficiently solved by increasing an electrostatic protection component in complete machine
Problem with grounding, while unnecessary metal steel disc is not required in fingerprint module body, can effectively reduce the overall dimensions of fingerprint module.
Obviously, those skilled in the art the utility model embodiment can be carried out various modification and variations without departing from
The spirit and scope of the utility model embodiment.In this way, if these modifications and variations of the utility model embodiment belong to this
Within the scope of utility model embodiment claim and its equivalent technologies, then the utility model embodiment is also intended to include these
