Embodiment
Below by drawings and Examples, the technical scheme of the utility model embodiment is described in further detail.
As shown in Figure 1, be the structural representation of the utility model embodiment mobile device, the utility model embodiment mobile device 1 comprises: metal shell 10 is used for electrostatic defending; Internal circuit 11 is placed in the described metal shell; Electrostatic defending module 12 is arranged between described internal circuit and the metal shell, and static and keep the shielding of metal shell to internal circuit is used to release.
As shown in Figure 2, schematic diagram during for the utility model embodiment charging of mobile devices, among the figure solid arrow be electrostatic current to, dotted arrow is the flow direction of leakage current, have a Y electric capacity 20 on the charger 2, mobile device 1 comprises metal shell 10, internal circuit 11, electrostatic defending module 12.
The design work voltage of electrostatic defending module 12 greater than civil power (＞220V), when charging normally by 2 pairs of mobile devices 1 of charger, Y electric capacity 20 electric leakages that 1 conduction is come for charger (＜100V), electrostatic defending module 12 just shows as the lower capacitive reactance characteristic of appearance value and is considered as open circuit, played the effect of isolating between Y electric capacity 20 and metal shell 10 paths, therefore being transmitted to metal shell has only very low floating pressure.Because the ESD circuit serves as electric capacity, itself has slight electric leakage, but the energy that arrives metal shell is also very weak, can not influence user's use.
In addition, when ESD affacted mobile device, static can be propagated by two kinds of channels.A kind of is the atmospherical discharges of induction, if act near the metal shell 10 of mobile device 1, because the shielding action of metal shell 10, static can be released by electrostatic defending module 12, protection internal circuit 11; Another kind is contact discharge, and static touches outer 10 shells of metal, and moment also can release by electrostatic defending module 12.
The leaky of the utility model embodiment metal shell during at charging of mobile devices increases the electrostatic defending module between metal shell and internal circuit earth point, charger is carried out effective isolation to the electric leakage of mobile device.Like this, when charger can produce tens volts the floating pressure that causes because of the Y capacity fall off, after being transmitted to mobile device by cable, owing to the buffer action of electrostatic defending module makes metal shell rise with respect to the current potential that the earth only has several volts, behind the human body touch, do not have tangible sensation, avoid causing the possibility of personal injury.
Among the utility model embodiment, the electrostatic defending module can be gas discharge tube, high-speed bidirectional diode, spark gap or piezo-resistance, directly is serially connected between operating circuit and the shell; Also can be that (Electro-Static Discharge, ESD) inhibitor also are directly to be serially connected between operating circuit and the shell for Transient Voltage Suppressor or low appearance value polymer static discharge; Perhaps being resistance algorithm network or inductance capacitor filtering attenuation network, is directly to be serially connected between operating circuit and the shell equally.As shown in Figure 3, use the structural representation of resistance (R) algorithm network for the utility model embodiment mobile device, R algorithm network 31 comprises the resistance R 1 and the capacitor C 1 of series connection between metal shell 10 and the internal circuit 11, and the two ends of resistance R 1 connect the resistance R 2 and the R3 of ground connection respectively.As shown in Figure 4, use the structural representation of inductance capacitance (LC) algorithm network for the utility model embodiment mobile device, LC algorithm network 32 comprises between metal shell 10 and the internal circuit 11 two capacitor C 1 and the C2 of series connection, connects the inductance L 1 and the L2 of ground connection respectively near the two ends of the capacitor C 1 of described metal shell 10.Certainly (Electromagnetic Interference, EMI) the special protection device also is fine to utilize the ESD/ electromagnetic interference.Static is with to keep metal shell just passable to the shielding of internal circuit as long as can realize releasing.
As shown in Figure 5, structural representation for the utility model embodiment portable electronic system, comprise mobile device 1 and charging device 2, mobile device 1 comprises metal shell 10, internal circuit 11, the Y electric capacity 20 that comprises the conducted interference of the Switching Power Supply itself of charging device when being used for reducing charging in the charging device 2, mobile device 1 also comprises electrostatic defending module 12, when 2 pairs of mobile devices 1 of charging device charge normally, Y electric capacity 20 electric leakages that 1 conduction is come for charging device, electrostatic defending module 12 shows as the lower capacitive reactance characteristic of appearance value to isolate the path of 10 of Y electric capacity 20 and metal shells.
Electrostatic defending module 12 can be for being serially connected in gas discharge tube, high-speed bidirectional diode, spark gap or the piezo-resistance between operating circuit 11 and the shell 10; Or described electrostatic defending module is Transient Voltage Suppressor or low appearance value polymer static discharge inhibitor, and Transient Voltage Suppressor or low appearance value polymer static discharge inhibitor are serially connected between operating circuit 12 and the metal shell 10.Electrostatic defending module 12 also can be for being serially connected in resistance algorithm network or the inductance capacitor filtering attenuation network between operating circuit 11 and the shell 10, the structure of the electrostatic defending module in its structure and the utility model embodiment mobile device is identical, repeats no more.
Therefore, the utility model embodiment is provided with the electrostatic defending module of these kinds between internal circuit and metal shell, can release static and keep the shielding of metal shell to internal circuit, solved of the influence of charging device Y capacity fall off, avoided causing the possibility of personal injury for mobile device.Providing for mobile device is having the ESD requirement of shelter, and a kind of solution route cheaply under can not fine elimination charging device Y capacity fall off situation.And not only mobile device can be dropped to minimumly when charging with charging device to the electric leakage of mobile device shell, and can keep the shielding action of metal shell, play the effect of electrostatic defending the mobile device internal circuit.
It should be noted last that, above embodiment is only unrestricted in order to the technical scheme of explanation the utility model embodiment, although the utility model embodiment is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical scheme of the utility model embodiment, and not break away from the spirit and scope of the utility model embodiment technical scheme.
