The present embodiments relate to mobile terminal 100 can be it is any possess communication and store function equipment, such as：
Tablet personal computer, mobile phone, electronic reader, remote control, personal computer (Personal Computer, PC), notebook computer,
Mobile unit, Web TV, wearable device etc. have the smart machine of network function.
Fig. 1 to Fig. 3 is refer to, example of the embodiment of the present invention one provides a kind of mobile terminal 100, including connection component 10, even
Connected components 10 include metal device 1, circuit board 3, fastener 5, housing 4 and connector 2, metal device 1, connector 2, circuit board
3 and housing 4 splice successively, fastener 5 sequentially passes through metal device 1, connector 2, circuit board 3 and housing 4 and connect with housing 4
Ground stud 41 is fastened together, in this way, metal device 1 and circuit board 3 then are kept into tight with the grounding screw 41 on housing 4
Solid connection, ensure that three has good ground connection, to reduce metal device 1 to the internal antenna devices 20 of mobile terminal 100
Influence.
In the present embodiment, metal device 1 is that the metal insert on loudspeaker is hardware inserts on loudspeaker box.Metal
Device 1 opens up the second through hole 1a, so that fastener 5 passes through.The metal device 1 is set close to the antenna assembly 20 of mobile terminal 100
Put, wherein, because metal device 1 is made up of metal material, therefore the radiation signal of the antenna assembly 20 of mobile terminal 100 can be made
Into interference, the reliability of mobile terminal 100 is influenceed.Certainly, in other embodiments, metal device 1 also can be other have by
Component made of metal material, such as metal clips etc..
In the present embodiment, the housing 4 has grounding screw 41.Specifically, housing 4 is the fore shell of mobile terminal 100, should
Housing 4 is mainly used in carrying the mainboard of mobile terminal 100.The opening position that the setting of metal device 1 is corresponded on housing 4 forms ground connection spiral shell
Post 41, the grounding screw 41 are substantially the part hardware insert of housing 4.It should be understood that the material of the hardware insert is closed for magnesium
Gold.
In the present embodiment, circuit board 3 opens up third through-hole 3a.Specifically, circuit board 3 is flexible PCB.On circuit board 3
Third through-hole 3a pass through for fastener 5.
In the present embodiment, connector 2 is used to be folded between metal device 1 and circuit board 3, and connector 2 includes top 21
