Abstract
The invention discloses a kind of electric elements and mobile terminal, for providing electrostatic defending for the electric elements in mobile terminal.Described electric elements include Electrostatic Discharge Sensitive and for described Electrostatic Discharge Sensitive provides the electrostatic protection apparatus of electrostatic defending, and described electrostatic protection apparatus is connected with described Electrostatic Discharge Sensitive.In the present invention, mobile terminal need not the structure of mobile terminal itself is carried out big change, simple.
Description
Technical field
The present invention relates to a kind of mobile terminal structure, particularly to a kind of electric elements and mobile terminal.
Background technology
ESD(Electro-Static discharge) the meaning be " Electro-static Driven Comb ", electrostatic Producing reason has
A variety of, including contact, separation or phase mutual friction etc..Electrostatic has long-time accumulation, high voltage, low electricity
The feature that amount, small area analysis and action time are short.Electrostatic can be described as ubiquitous in our daily life,
With surrounding just with the highest electrostatic potential, several kilovolts of even several ten thousand volts on our body.These electrostatic are the most right
Human influence is little, but for some electric elements to electrostatic sensitive, it the most directly can be made to lose itself
Due normal performance, even completely loses normal function.Most of mobile terminal (the examples commonly used due to us
Such as mobile phone, panel computer) in, there are a lot of this kind of electric elements, so when manufacturing and designing, ESD prevents
Protect the most extremely important.
For the consideration of electrostatic defending, the Air Filter of the sender of mobile terminal the most all uses non-metallic material
Matter, in order to the discharge path of electrostatic isolation, but the hardness of non-metallic material is inadequate, easily subsides, deforms,
Cause bad order.
And present smart mobile phone is substantially all equipped with proximity transducer, its major function is can be in call
Time human body proximity mobile phone detected, thus close screen power saving.The position of proximity transducer is general and receiver is tight
Neighbour, therefore when the sender Air Filter of metal material must be used in order to add strong hardness, proximity transducer
Electrostatic defending just become a difficult problem, in the case of especially structure can not significantly be changed, especially difficulty.

Detailed description of the invention
Embodiments provide a kind of electric elements and mobile terminal, in order to the electrical equipment in mobile terminal
Element provides electrostatic protection.
Based on above-mentioned purpose, as the example of an optional realization, as it is shown in figure 1, the embodiment of the present invention is first
Providing a kind of electric elements, described electric elements include Electrostatic Discharge Sensitive 2 and for electrostatic sensitive unit
Part 2 provides the electrostatic protection apparatus 3 of electrostatic defending, wherein, electrostatic protection apparatus 3 and Electrostatic Discharge Sensitive
2 are connected.
The present embodiment is when implementing, and electrostatic protection apparatus 3 is by the way of electric, as passed through power line
Set up with Electrostatic Discharge Sensitive 2 and be connected, or, electrostatic protection apparatus 2 is by the way of physics, such as colloid
The mode of bonding is set up with Electrostatic Discharge Sensitive 2 and is connected.
This example is by arranging electrostatic protection apparatus to Electrostatic Discharge Sensitive, so that at Electrostatic Discharge Sensitive
When around having Electro-static Driven Comb, the electrostatic around Electrostatic Discharge Sensitive can be completely cut off or release by electrostatic protection apparatus
It is put into certain (as on the ground), thus reaches Electrostatic Discharge Sensitive is provided the purpose of electrostatic defending.
In this example, electrostatic protection apparatus 3 is the most multiple, such as electrostatic discharge protection circuit or/and insulator etc.
There is the device of antistatic protection function；
When electrostatic protection apparatus 3 is electrostatic discharge protection circuit, electrostatic protection apparatus 3 and Electrostatic Discharge Sensitive 2
The mode being connected can be: the input of electrostatic discharge protection circuit at least with a pin of Electrostatic Discharge Sensitive 2
It is connected；
The present embodiment is when implementing, and the input of electrostatic discharge protection circuit can have one or more pin, respectively
Pin can be connected respectively in the way of correspondence and one or more pin of Electrostatic Discharge Sensitive 2 are by power line,
Here, the outfan of electrostatic discharge protection circuit can control, in order to this electrostatic discharge protection circuit as a certain equipment,
During such as mobile phone, the outfan of this electrostatic discharge protection circuit can be received a certain datum line in mobile phone, as
On ground wire, so, when having Electro-static Driven Comb around Electrostatic Discharge Sensitive, this electrostatic discharge protection circuit can be by quiet
Around electric sensitive element, the Electro-static Driven Comb of release is on the ground, reaches Electrostatic Discharge Sensitive is carried out electrostatic protection
Purpose.
Electrostatic discharge protection circuit described in this example can by one or more transient supression diode TVS or/and
The electrostatic protection devices such as varistor are constituted,.
When electrostatic protection apparatus 3 is insulator, electrostatic protection apparatus 3 is connected with Electrostatic Discharge Sensitive 2
