In addition, on circuit design, usually can plan the earth point of different functions, be broadly divided into power ground point and data-signal earth point etc.And because the present invention is in order electrostatic discharge protective to be provided, therefore in design, preferably to select to be used as by the power ground point approach of leading off of static discharge, avoid the electronic component on the static discharge damage electronic installation, being chatted first bright at this.
Please refer to Fig. 1, be the block schematic diagram of the embodiment of the electronic installation of tool electro-static discharge protection function of the present invention.As shown in the figure, the electronic installation shown in the present embodiment is to be designed to a battery pack illustrate, and is used for being applied in an application system, and with the power supply source as this application system, it comprises: a conductive shell 1, a circuit board 2 and at least one battery 3.Wherein, conductive shell 1 can directly adopt conductive material (for example metal) to design on actual design, can certainly be to adopt non-conductive material (for example plastics), but form conductive shell 1 by plating or other known technology.
Certainly, electronic installation is except the design form of battery pack, affiliated those skilled in the art can understand, generally be used to provide the electronic installation of specific function in the design of power supply source of supply, also can be divided into the power supply of direct reception battery 3, or adopt the different power supply conversion elements such as voltage regulator, DC-DC converter, AC/DC converter to receive the power supply of external power source (as: universal serial bus (USB), civil power), operate required electric energy to be converted to electronic installation.And no matter under the design form of which kind of power supply source of supply, power ground point 200 all is directly to be used as the required earthed circuit of power supply source of supply by wiring.
The guiding path 21 of having ready conditions further comprises: an electrostatic discharging element 211 and a conducting element 212.Wherein, an end of electrostatic discharging element 211 is to be electrically connected power ground point 200, so with the circuit form of power supply source of supply (negative pole of the battery 3 of present embodiment) formation one earth of electronic installation.On characteristic, when one pre-conditioned (for example being higher than a voltage quasi position) is satisfied with in the voltage difference variation at electrostatic discharging element 211 two ends, electrostatic discharging element 211 conductings; And be not content with this when pre-conditioned when the voltage difference at electrostatic discharging element 211 two ends changes, electrostatic discharging element 211 is to be equivalent to a high-impedance component for power ground point 200.In other words, the conducting short circuit phenomenon of electrostatic discharging element 211 is to follow overdrive voltage to occur.Subsidiary one what carry is that above-mentioned electrostatic discharging element 211 pre-conditioned is that the element characteristic by electrostatic discharging element 211 decides.The pre-conditioned specification that adopts during as for design then is to select different electrostatic discharging element 211 according to actual required electrostatic discharge protective, there is no in the present embodiment and is limited.
One fixed connecting end of conducting element 212 is the other ends that are electrically connected electrostatic discharging element 211, and a contact jaw of conducting element 212 is entity electrical contact conductive shells 1.Thus, allow and have ready conditions guiding path 21 as the conducting path between conductive shell 1 and the power ground point 200.
It should be noted that, if directly conductive shell 1 is connected to the negative pole of battery 3, this design can cause shell conductive shell 1 electronegative, possibly can't meet the safety of product, and causes the problem of fail safe because generation current between different current potential flows to generate heat easily.Because heavily fail safe of battery product head, so the present invention is under take security consideration as prerequisite, aforesaid circuit framework is proposed.Circuit characteristic with regard to this circuit framework, electrostatic discharging element 211 is under preset state, namely the voltage difference at electrostatic discharging element 211 two ends changes and not yet to be satisfied with when pre-conditioned, and electrostatic discharging element 211 is open-circuit conditions of formation one high impedance for power ground point 200.Therefore, by the have ready conditions characteristic of conducting of electrostatic discharging element 211, not yet produce at conductive shell 1 under the state of static discharge, the guiding path 21 of having ready conditions can effectively intercept conductive shell 1 and be connected 200 directly connections with power ground, avoids conductive shell 1 with putting the electrode potential that 200 essence equate with power ground; And produce static discharge phenomenon and when satisfying electrostatic discharging element 211 pre-conditioned with the voltage difference of power ground point 200 when conductive shell 1, the guiding path 21 of having ready conditions can be transmitted to power ground point 200 with the electrostatic charge of accumulating on the conductive shell 1 again effectively, leading off by the negative pole of battery 3, and reach electrostatic discharge protective.
What further specify is that electrostatic discharging element 211 can adopt the element design wherein such as capacitor, rheostat (Varistor) and transient voltage suppresser (Transient Voltage Suppressor, TVS).Right above-mentioned example is not limitation of the present invention, as long as can carry out conditionally as described in the present invention the well known elements of conducting, all can be the present invention and adopts.
Capacitor is by the two ends metal material, and the centre is again every being formed with megohmite insulant (medium), and therefore can allow between conductive shell 1 and the power ground point 200 is to form open circuit.And medium is that its dielectric strength (Dielectric Strength) is arranged, refer to the maximum voltage value that the unit thickness of this medium can bear, so-called breakdown voltage (Breakdown Voltage) namely, being scaled unit of account, namely is the change in voltage (that is aforesaid electrostatic discharging element 211 is pre-conditioned) in the unit interval.So when moment produced static discharge after the conductive shell 1 accumulation electrostatic charge, the voltage that raises suddenly can make the electrostatic charge of accumulating on the conductive shell 1 pass medium, allows capacitor form the phenomenon of conducting.Electrostatic charge with accumulation on the conductive shell 1 conducts to power ground point 200 thus.
Rheostat (claiming again piezo-resistance), when the voltage of accepting is normal (surpass voltage quasi position), rheostat is to have high impedance and be good insulating body, so that formation is opened a way between conductive shell 1 and the power ground point 200.But when moment produced static discharge after the conductive shell 1 accumulation electrostatic charge, the voltage that raises suddenly can allow rheostat collapse (tool Low ESR) and form conducting, and a voltage quasi position of its collapse namely is the pre-conditioned of aforesaid electrostatic discharging element 211.Therefore, the rheostat of conducting this moment can conduct to power ground point 200 with the electrostatic charge of accumulation on the conductive shell 1.
Transient voltage suppresser is a kind of rheostat of tool voltage interdependence, and its principle and rheostat are roughly the same.After voltage is increased to a voltage quasi position (aforesaid electrostatic discharging element 211 pre-conditioned), can cause the impedance fast-descending of transient voltage suppresser, allow the electrostatic charge of accumulation on the conductive shell 1 can be from transient voltage suppresser by being transmitted to power ground end 200.In addition, transient voltage suppresser is to have lower clamping voltage (Clamping Voltage) compared to rheostat, more can promptly electrostatic charge be transmitted to power ground end 200.
On the other hand, 212 of conducting elements are can be such as the design of the organ that adopts one of them or the combination in any such as shell fragment, thimble, screw and spring.One end of conducting element 212 is that firm connection (for example welding) circuit board 2 and electrostatic discharging element 211 are electrically connected, but the contact jaw of conducting element 212 electrical contact conductive shell 1 then.
Certainly, the kind of the above-mentioned electrostatic discharging element of giving an example 211 and conducting element 212 is not limitation of the present invention, and any element with identical characteristics and effect all is to belong to the scope that the present invention protects.

And then, circuit board 2 is again through electronic component assembling technique, surface mount technology technique (SMTProcess) for example, firmly connect respectively (for example welding) in the first affixed point 2011 and the second affixed point 2012 with the two ends with electrostatic discharging element 211, and the fixed connecting end of conducting element 212 firmly is connected in the affixed point 202 of conducting element.Right other known method that electrostatic discharging element 211 and conducting element 212 firmly can be connected in addition all can be the present invention and adopts.
The electronic installation of present embodiment is still and utilizes battery 3 to be used as the power supply source of supply to be illustrated.Affiliated technical field technical staff can understand, and battery 3 is to be connected with circuit board 2 by at present known method (for example welding).In addition, because the present invention leads electrostatic charge off by power ground point 200, so only to indicate power ground point 200 among Fig. 2 are negative poles that correspondence couples battery 3, and as for just no longer other sign and the description of the firm affixed point that connects of anodal institute of battery 3.Certainly, if the power supply source of supply of electronic installation is to adopt the power supply conversion element to accept external power source, just then the power supply conversion element can be finished firm connection by SMT technique.
From the above, architecture design by present embodiment, when electronic installation integral body is finished assembling, the contact jaw of loam cake 11 meeting entity electrical contact conducting elements 212, and by conducting element 212 and electrostatic discharging element 211 formed have ready conditions guiding paths 21 and 200 electric connections of power ground point.Thus, with the design of the electronic installation of finishing tool electro-static discharge protection function of the present invention.
Further the actual form with battery pack illustrates, because in the design of battery pack, insulation is very important, if the conductive shell of battery pack 1 is charged, might causes the situation of short circuit and causes danger.Therefore, by design of the present invention, when the potential difference of conductive shell 1 and power ground point 200 was higher than the accurate position of predeterminated voltage, the guiding path 21 of having ready conditions can form conducting states, in order to effectively leading electrostatic charge off with power supply earth point 200; When this potential difference was not higher than the accurate position of predeterminated voltage, 21 of the guiding paths of having ready conditions can form open-circuit condition, allow conductive shell 1 can be not therefore with the current potential of power ground point 200.Thus, to strengthen the fail safe of battery pack.
What remark additionally is, because the electronic installation of present embodiment is to use conductive shell 1, therefore when electronic installation has that needs are embedded to be installed in application system (for example: above-mentioned battery pack is to be installed in application system inside in use), then can be further carry out electrical contact by conductive shell 1 and a conductive part (not shown) of application system, another that is used as static discharge with the grounding design by application system led approach off.To this, relevant additional design all is the scope that the present invention can be applied.

Then, the guiding path of having ready conditions maintains open-circuit condition, until the voltage difference of conductive shell and power ground point is when being higher than this voltage quasi position, the guiding path of having ready conditions forms a conducting state (S305), conducts to power ground point (S307) with the electrostatic charge of will be accumulated on the conductive shell.
In step (S307) afterwards, the high voltage that moment produces is after the leading off of electrostatic charge, allow the voltage difference of conductive shell and power ground point be lower than voltage quasi position, the guiding path of therefore having ready conditions reverts to default open-circuit condition (S309) because of the characteristic of electrostatic discharging element.At last, repeated execution of steps (S305) and steps flow chart thereafter thereof are to finish present embodiment for means of defence that static discharge was provided.
