When upper, due to being provided with protective layer 13 in the outside of shell fragment pad 11, so as to which liquid is blocked in into shell fragment pad 11
Periphery, can effectively prevent shell fragment pad 11 from being contacted with liquid, can avoid or reduce corrosion of the liquid to shell fragment pad 11,
And then the reliability of mobile terminal can be improved, it is possible to extend the service life of mobile terminal.
It is understood that (" root of shell fragment pad 11 " is finger playing piece pad 11 for the root of shell fragment pad 11
Periphery edge) it is the weak part of shell fragment pad 11, the liquid of entrance is easily accumulated in the root of shell fragment pad 11 and easily to shell fragment
Cause serious corrosion in the root of pad 11.Thus, can be with barrier liquid and shell fragment pad by setting above-mentioned protective layer 13
11 root contact, the weak part of protection shell fragment pad 11.Moreover, it is also possible to prevent the root of liquid corrosion shell fragment pad 11
Crept up afterwards along shell fragment 3 and corrode shell fragment 3 itself.Thus, it is possible to improve the life-span of shell fragment 3, it is possible to improve button 2 with
The reliability that circuit main board 1 is connected, so as to improve the reliability of mobile terminal, extends the service life of mobile terminal.
In addition, by setting above-mentioned protective layer 13, being also prevented from due to the corruption that liquid corrosion shell fragment pad 11 is produced
Electromigration occurs on circuit main board 1 and occurs short circuit with the dew copper near shell fragment pad 11 for erosion liquid, so as to improve movement
The reliability of terminal, it is ensured that mobile terminal can be used with moderately good run.
Mobile terminal according to embodiments of the present invention, is protected by being set in the periphery of shell fragment pad 11 corresponding with button 2
Sheath 13, can surround at least a portion of shell fragment pad 11, so as to effectively prevent shell fragment pad 11 and liquid from connecing
Touch, so as to avoid or reduce corrosion of the liquid to shell fragment pad 11, improve the reliability of mobile terminal, it is possible to which extension is moved
The service life of dynamic terminal.
Mobile terminal according to embodiments of the present invention is described in detail referring to Fig. 1-Fig. 4.
Reference picture 1- Fig. 4, circuit main board 1 is located in shell and circuit main board 1 is provided with shell fragment pad 11, and button 2 is located at
On shell, one end (lower end of middle shell fragment 3 referring to Figures 1 and 2) of shell fragment 3 is connected and the other end (reference picture 1 with shell fragment pad 11
With the upper end of shell fragment in Fig. 2 3) it is connected with button 2.Thus, button 2 can be realized with circuit main board 1 by shell fragment 3 and electrically connected.
Referring to Figures 1 and 2, mobile terminal also includes the button circuit board 4 for being used to connect button 2 and shell fragment 3, key circuit
One end (right-hand member of button circuit board 4 in reference picture 1) of plate 4 is connected with button 2 and the other end (button circuit board 4 in reference picture 1
Left end) be connected with the above-mentioned other end (upper end of shell fragment 3 in reference picture 1) of shell fragment 3.Alternatively, button circuit board 4 can be
FPC plates (Flexible printed circuit (board), flexible printed circuit board).
Further, the above-mentioned other end of button circuit board 4 is provided with conductive welding disk 41, and the above-mentioned other end of shell fragment 3 is with leading
Electrical bonding pads 41 are abutted.Thus, abutted by shell fragment 3 with the conductive welding disk 41 on button circuit board 4, button 2 and circuit can be made
Mainboard 1 realizes good electrical connection.
Reference picture 1- Fig. 4, circuit main board 1 is provided with the protective layer 13 for being used for protecting shell fragment pad 11, and protective layer 13 is surrounded
The whole periphery of shell fragment pad 11 is set.Thus, it is possible to which liquid to be preferably blocked in the periphery of shell fragment pad 11, preferably keep away
Exempt from or reduce corrosion of the liquid to shell fragment pad 11.
Alternatively, protective layer 13 can be white oil silk-screen layer.For example, white oil can be coated in into bullet by way of silk-screen
The outside of piece pad 11.As a result, technique is simple, cost is low, and white oil silk-screen layer can barrier liquid and bullet well
Piece pad 11 is contacted.In addition, white oil silk-screen layer also have good insulating effect, can further avoid shell fragment pad 11 with
Neighbouring dew copper short circuit.
Certainly, protective layer 13 is not limited to above-mentioned white oil silk-screen layer, and protective layer 13 can also be insulating trip, such as protective layer
13 can be PC (Polycarbonate, makrolon) piece.PC pieces can be pasted onto the periphery of shell fragment pad 11；Or PC pieces
The through hole with the form fit of shell fragment pad 11 can also be provided with, now PC pieces can directly be set in the whole outer of shell fragment pad 11
In week, facilitate the installation of PC pieces.
Alternatively, reference picture 4, the radial width L of protective layer 13 can be 1.0mm-1.5mm.Thus, protective layer 13 is set
Put in appropriate width, good barrier effect can be played, prevent the contact of liquid and shell fragment pad 11, while can also keep away
Exempt from protective layer 13 to take space more on circuit main board 1 and influence the other elements on circuit main board 1 or wiring.
In some embodiments of the invention, reference picture 3 and Fig. 4, circuit main board 1 is provided with solder mask layer 12, protection
Layer 13 is located on solder mask layer 12.Thus, by setting protective layer 13 on the solder mask layer 12 around shell fragment pad 11,
It can make to be higher by shell fragment pad 11 around shell fragment pad 11, so as to which liquid preferably is blocked in into the outer of shell fragment pad 11
Enclose, more efficiently prevent from the contact of liquid and shell fragment pad 11, can preferably play a part of preventing shell fragment pad 11 from corroding.
Alternatively, the thickness d of protective layer 13 can be 0.01mm-0.1mm.Fitted thus, it is possible to make protective layer 13 be higher by shell fragment pad 11
When distance, so as to which liquid to be effectively blocked in the periphery of shell fragment pad 11, prevent liquid and contact pads.
Wherein, shell fragment pad 11 can include spaced multiple (such as six), now leading on button circuit board 4
Electrical bonding pads 41 are also provided accordingly to six, and above-mentioned one end of each shell fragment 3 is connected with corresponding shell fragment pad 11, each shell fragment
The 3 above-mentioned other end is abutted with corresponding conductive welding disk 41.The periphery of each shell fragment pad 11 is all provided with matcoveredn 13.It is located at every
The protective layer 13 of the individual periphery of shell fragment pad 11, can be set around the whole periphery of shell fragment pad 11, it is possible thereby to so that each
Shell fragment pad 11 is protected well, preferably avoids or reduce corrosion of the liquid to shell fragment pad 11.
Further, the protective layer 13 between two neighboring shell fragment pad 11 can be connected as one.As a result, protection
The setting of layer 13 is more convenient, and can preferably protect shell fragment pad 11, prevents adjacent shell fragment pad 11 from causing phase because of corrosion
The adjacent short circuit of shell fragment pad 11, improves the reliability that mobile terminal uses process.
For example, when protective layer 13 is white oil silk-screen layer, the protective layer 13 for being arranged on multiple peripheries of shell fragment pad 11 can be with
Being by disposable silk-screen can be by white oil silk-screen in precalculated position, so as to be respectively formed in the periphery of each shell fragment pad 11
There is the protective layer 13 being made up of white oil silk-screen layer.For another example when protective layer 13 is PC pieces, can be provided with and multiple bullets on PC pieces
The one-to-one through hole of piece pad 11, disposably directly can be set in multiple peripheries of shell fragment pad 11 by PC pieces.Thus, make
Protective layer 13 setting technique it is simple and anticorrosion ability is good.
